Abstract

The invention relates to devices for securing parts on a table of a milling machine. The aim of the invention is the spread of technological capabilities in the processing of stepped shafts with a large diameter in the middle and smaller diameters at the ends. On the stationary part 1 of the table, there are fixed 4 and mobile 3 centers, and on the rotary part 8, centralizers 6 and 7, mounted with springs 9, are installed. and 4, moreover, the shoulder of the shaft 5 moves the centralizer 7 to the left, compressing the spring 9. The milling cutter 16 processes the keyway when moving the table 2 to the left in the working feed. After machining one end of the shaft 5, the pneumatic cylinder moves the center 3 to the right and the spring 9 retracts the shaft 5 out of contact with center 4. Yes its derivatives turn portion T 8 180 ° and the second end of the shaft 5 enters the treatment area. 2 Il. WITH tNO 00 with

structure, and more specifically to devices for securing parts on the table of a milling machine.

The aim of the invention is to improve the technological potential when machining stepped shafts with a large diameter in the middle and smaller diameters at the ends.

FIG. 1 shows a table, a general view in FIG. 2, section A-A in FIG. one.

A two-turn rotary table contains a fixed base 1, which is attached to table 2 of a milling machine. On the stationary base there is a movable 3 and a fixed 4 centers, which are used to fix the shaft 5 being machined in the centers. For centering the shaft, the right 6 and left 7 centralizers mounted on the rotary part 8 of the table 2 and spring-loaded 9 springs are used

Moving the table of the milling machine to the left and to the right is fixed by stops 10 and 11e, which, when the table is moved, are pressed against buttons 12 and 13. On the rotary part there is a button 14 connected to the pneumatic clamp 15,

The two-position table works as follows

With the help of the robot, the shaft to be machined is mounted on the central cylinders 6 and 7 so that the shoulders of the shaft 5 are located between the central gun, sh. The processed shaft 5 with its surface nalshma et button 14, which enters into operation

Pneumatic clamp 15, and occur

In this case, the left shoulder shaft moves the centralizer 7 to the left, then the engine start is started to move the table 2 to the left at the working feed. At this time, the milling tool 16 processes the groove at one end of the shaft.

only the table reaches the desired place, the support 10 located on the table of the milling flock presses button 12 and the movement of the table stops. When the table is accelerated, the table returns to its original position, and the shaft is expanded.

The left centralizer 7 removes the shaft from the left fixed center 4 and the first rotation of part 8 takes place, the rotation continues until the latter with its abutment presses the button (not shown).

After stopping, the second shaft clamp occurs in the centers. When the engine is turned on, the table moves to the left at the working feed, at which the milling cutter 16 processes the thinnest groove at the other end of the shaft 5, after which the table returns to its original position in an accelerated movement.

The motor stops and turns 6aTfjiBaeMbnt shaft, stuck in the centers, is released from the latch. Then, a reverse rotation of the rotary part of the table occurs, the shaft returns to its original initial position. A common stop occurs and the robot removes the machined part.
