Knee-type milling machine – one of the most common types of equipment. The fixture design includes a slide and a working console. The movement of the working part is carried out in three directions: longitudinally, vertically and transversely. Aggregates are divided into fixed models with horizontal, vertical milling machine variations and standard modification. On the basis of the considered equipment are available copy, software managed instances and their options combined.
Below is a General diagram of the device of the equipment:
1 – skeleton (frame).
2 – electrical equipment.
3 – box-shifter.
4 – host speed control.
5 – a slide with a table.
6 console.
7 – power supply.
Knee-type milling machine designed to perform appropriate operations using mechanical, disc, corner, and other cutters. The equipment is available to handle a variety of workpieces suitable size. Material suitable for participation in the working process – cast iron, nonferrous metals, plastic, steel and other alloys.
Analog turntable can handle screw socket on cutting parts of the tool. A universal model is designed for a variety of milling procedures, including boring and drilling work in experimental or single production. Often systems are used in large-scale production of various parts.
This equipment is designed for machining of compact dimensions, mainly from nonferrous metals and their alloys and products made of plastic and plastic. Furthermore, this device is designed for roughing steel, cast iron. The whole process happens in automatic mode for a given cycle.
Knee-type milling machine with a table width of 200 mm is used for machining small parts from steel, cast iron, plastic and nonferrous metals. The production of this equipment is established at the Vilnius plant for production of machine tools. Practiced the release of three models of units: horizontal version 6М80Г universal counterparts 6М10 and copying machines of the type 6П10К.
One More manufacturer of milling machines – Dmitrovsky factory, which produces samples of the series "R". Among them: 6Р81Г, 6Р81Ш, 6Р11. All units are standardized, operate automatically, have a reverse and a standard transmission. Previously, the plant produced the simplified console versions of the series "N" and "G".
Knee-type milling machines of this type are equipped with an electric motor capacity of 5.5 kW with revving 1450 rotations per minute. They are widely used in engineering and industry. The labor movement is transmitted via two types of transmission: 35/27 either 21/41. Diagram of milling machine indicates that the number is notched gear depends on the number of teeth. Thus, the equipment can operate at two different speeds. The right tool depends on constant module coupling gear, which should be stable with a pair of aggregation between the wheels.
The Kinematic diagram of the machine includes structure diagram during rotation of the spindle. The net number of revolutions is related to the number and nominal value of the included gear. The distance between the vertical and horizontal guidelines depends on the chosen scale in the process.
The Intersecting point of vertical and horizontal identical amount of momentum at any stage of the work spindle. Functioning shafts between themselves aggregate by coupling via a toothed wheel (gear). As a rule, the number of these modules is 61 or 62 units.
In the case of transmitting motion from one shaft to another element, there are several stages (2, 3, 4 and more). The final indicator is calculated according to the formula m*n. For example, 2*4 = 8 different speeds.
In the passport console-milling machine indicates that it consists of a frame, electrical parts, feed boxes, console, switch, table and the sled. Managing and configuring the unit via the following elements:
The Node switching speeds multi-purpose knee-type milling machine located in the housing made of cast iron, aggregation with the shaft speed is realized through a flexible coupling. The spindle of the reporting unit – shaft with three point support. Its accuracy is determined by the special bearings. Another item intended to retain the shank of this node.
The Axial clearance is adjusted by grinding the locking rings. The increased backlash can be removed by treatment of the half-rings and locking nuts. For lubrication of the gearbox meets the plunger pump, the performance of which is 2 liters per minute. Other parts of the mechanism receive the lubricant by the method of splashing from the tube, located above the control unit of velocity.
Box of switching of speeds of this model gives an opportunity to choose the desired mode without series of intermediate stages. The working rail is moved using the handle provided. The roller axis is moving after exposure to the plugs and drive controller in the axial direction. Then knee-type milling machine 6Р82 device and circuit of which more will be discussed further, it operates with a bevel gear and pointer speeds. The disc has holes, which engage in pairs with the gear.
Spring is adjustable by means of a tube retainer mounted in the lock by turn with normal force. The handle control mode is fixed by a spring and ball element. In addition, the spike of the handle engages with the groove of the flange. It should be noted that the bevel gear backlash must not exceed 0.2 mm. Disk with this indicator can be rotated by up to 1 millimeter.
This site provides obtaining a working feed and speed of movement of the console, slide and table. When you move the impulses are transmitted to the shaft with safety coupling and sleeve which are joined together by the dowel and the output shaft. The disk friction part of the block aggregates with the bushing and the roller. When activated, Cam clutch, torque is transmitted to the nut, gears, and drives.
Box switch feed universal knee-type milling machines are placed in the frame. The principle of operation of this node is similar to the speed unit. From the axial displacement of the drive is protected with a roller, which is locked by means of a pair of balls and bushings. The locking disk is made by means of identical parts connected with shaft by key.
The following is a schematic vertical knee-type milling machine (box feed) and explanations.
1 – locking roller.
2 – bushing.
3 – annular groove.
4 – a claw clutch.
5 – the handle of the control.
6 – a pair of balls.
7 & 8 – working disks.
9 – control the ball.
10 – disk switch
11 – gear.
12 – pointer speed.
13 – torque shaft.
14 – nut.
15, 16, 17, 18 – snap rings and retainers.
For comparison, consider two of the most popular models of machines. Let's start with the characteristics of the modification 6Р82:
Modification 6Р82Г characterized only by mass (2,83 t), and also limit the distance from horizontal spindle axis to working surface (450 mm).
Technologically, series “R” more refined in terms of the longitudinal stroke of the working table (100 mm). Precise setting of the surfaceproduced by the upgraded attachment of the limbs. In addition, this equipment has the optimum configuration that meets the modern standards of technical aesthetics. All the basic components of the considered machines harmonized with each other.
Additional convenience when operating and managing versions of “M” and “R” is provided by automated cycle and options such as:
Milling machines modifications “M” and “R” adjusting the longitudinal travel of the table is carried out in automatic or semi-automatic mode. At the unit production control feeds manually, including the rapid movement of the table. Mass production involves the use of automatic and semi-automatic ranges. In fact, these modes represent the hopping and the pendulum mode of action.
To configure the process appropriately in a T-shaped groove on the side is the distance between the Cams for a particular indicator. These elements at the right moment act on a test asterisk fast working movements of the table on the shift knob longitudinal feed, which gives the opportunity to ensure equipment operation in a given cycle.
The Main working cycles of milling machine are listed below:
The tuning Process is performed in the following sequence:
Knee-type milling machine price in Russia starts from 120 thousand rubles to help qualitative processing of workpieces of steel, cast iron, plastic and nonferrous metals. The equipment can be used for single or series production. Technique allows one to obtain details on the various configuration slots gears and teeth. In addition, milling may be performed according to the rotation of the table around its own axis by 45 degrees. The accuracy category of the press belongs to the class of «N» (normal). Additional applications of the unit available when operating invoice of the working head, dividing analogues and the rotary working surface.
