SU375178A1 - COPIER-MILLING MACHINE FOR TREATING WOODEN BLANKS - Google Patents

Description

The invention can be used in the shoe and woodworking industry.

A copy milling machine for processing wood blanks is known, which includes a frame, a rotary table, knife heads, a mechanism for clamping blanks on a table, switches mounted on a frame and interacting with pressure cylinders.

The purpose of the invention is to provide the possibility of treating wedge-shaped heels and applying heel size to the surface of the workpiece.

This is achieved by the fact that the mechanism for clamping blanks is made with a pressure plate installed rotatably about its vertical axis, and the pressure plate is equipped with a digital mark.

FIG. 1 shows the kinematic diagram of the machine, general view; in fig. 2 - the same view in the place; in fig. 3 - diagram of the mechanism for the installation of blanks.

On the frame on tapered roller bearings mounted rotary table 1, in the center of which is mounted distribution pneumatic crane. In the case of a pneumatic tap consisting of a base 2 and a cover 5, a valve 4 is inserted, lapped to the surface of the cover.

A roller 5 is inserted into the upper slot of the spool having openings for supplying compressed air. The roller is fixed and when the table and the distribution housing rotate.

pneumatic crane keeps the valve in a fixed position. The pneumatic crane's nadzolotnikov cavity is connected through a hole and a 190-groove located in the lower plane along the 190 ° arc in the spool, as well as through holes in the lid with pneumatic cyclides 6 when clamping the blanks. On the lower plane, the valve has a 150 ° arc and a radial groove connecting the pneumatic cylinders through the openings in the lid to the atmosphere when the blanks are released.

On the table there are four mechanisms for setting the blanks. Each mechanism consists of a croisteal 7, rigidly attached to the table. A replaceable copier 8 having the form of a heel and a pressure plate 9, which can rotate about its vertical axis, are attached to the bracket from above, which makes it possible to obtain different rear corners of the heels.

On the mounting plate there is a digital marking machine 10, which, when clamping blanks, applies heel size to their surface.

To the rod of the pneumatic cylinder is attached the bottom pad 11, on which is mounted

stocking. The platform together with: the rod can move vertically.

Cams 12-M are attached to the table to control the supply of close air to the pneumatic cylinders. The rotation of the table is carried out by the electric motor 15 through the V-belt transmission 16 and the worm gear 17.

On the bed, two swinging knife heads 18 and 19 are mounted, which can be pressed to the copiers by means of an air cylinder 20 and 21. The heads are driven from the electric motor 22 via a V-belt drive 23.

On the frame installed pneumatic spreader 24 and switches 25-27.

The machine works as follows. The pressure plates 5 are rotated relative to the axis and the predetermined heel angle is fixed. The workpiece at the loading position is installed on an open platform 11. When the table rotates / rotates, the casing of the distribution pneumatic crane and the roller 5 and the spool 4 remain in a fixed position. In the lid 3, the hole connected to the pneumatic cylinder Ndrom 6 approaches the slot of the zolotka 4. Compressed air is fed into the pneumatic cylinder through the holes in the roller 5 and the valve 4, the workpiece is pressed to the upper platform 9, and heel size. After further rotation of the table, the cam 12 locates on the roller of the switch 25, which through the distribution pneumatichiol from access to compressed air in the pneumatic cylinder 20.

The knife head 18 is pressed against the copier 8, one side of the workpiece is milled. At the end of the milling, the cam 12 comes off the roller of the pneumatic end switch 25, and through the distribution pneumatic inlet, the compressed air enters the other cavity of the pneumatic cylinder, resulting in the knife head moving away from the copier. As the table rotates further, the cam 13 locates the roller of the switch 26, which through the distribution pneumatic hammer allows access to compressed air to the pneumatic cylinder 21 of another knife head 19. The knife head is attached to the copier, and the other side of the workpiece is milled. At the end of the milling, the cam 13 comes off the roller of the end pneumatic switch 26, and through the distribution pneumatic hammer, compressed air enters the other cavity of the pneumatic cylinder, with the result that the knife head moves away from the copier.

With further rotation of the table, the hole in the lid 3, connected to the pneumatic cyclide, approaches the slot of the spool 4 connected to the atmosphere. Compressed air escapes from the pneumatic cylinder to the atmosphere, and the stem depresses the workpiece with a spring. After that, the cam 14 locates a switch 27 on the roller, which provides compressed air to the pneumatic ejection cylinder 24. The treated heel is dropped from the platform.
