Abstract

The invention relates to the treatment of curved surfaces and is intended for processing, in particular, automobile brake linings. The purpose of the invention is to simplify the device. The workpiece 19 is placed on the bed 15, which carries clamping levers 18, which are installed in contact with the copiers 20. As they move away from the bed feeder with the levers, they turn and fix the product. At the same time, the infeed is delivered. 4 il. (rig.s

Nzobroveine relates (.: to the area of machining of curved surfaces of the surfaces in particular of automobile brake linings.

The purpose of the invention is to simplify the device by using a single drive for fixing the workpiece and feeding it into plunging.

FIG. 1 shows the device, front view; in fig. 2 is a view A in FIG. in fig. 3 - the mechanism of clamping the product; in fig. 4 - view B on fig.Z.

The device consists of the frame 1, the drive 2, the spindle head 3, the tension mechanism of the abrasive belt 4, the clamping mechanism 5 (fixation), the feed mechanism 6 and the magazine 7. The drive 2 is designed to communicate the rotational movement to the spindle 8 mounted in the spindle head 3.

A contact roller 9 is mounted on the spindle 8. The abrasive tape 10 is put on the pin 9, the tension 11 and the intermediate 1 2 rollers. The abrasive belt tightening mechanism is designed to set, tension and adjust the position of the abrasive belt. The tensioning roller 11 is moved with the help of the pneumatic cylinder 13, the clamping mechanism 5 consists of the pneumatic cylinder 14, on the rod of which the bed 15 is fixed, moving along the columns 16. In the bed 15 nA axes 17 clamping levers 18 are fixed to fix the workpiece 19. Levers 18 are pressed to the planes of the copiers 20 by means of the spring 21. The copiers 20 are fixed on the bed 1 stationary so that the plane of the upper portion of each of the copiers is perpendicular to the generatrix of the contact roller 9. In contact with the product I9, the support plates 22 of the levers 18, located on the right side of the clamping mechanism 5, are spring-loaded with a rubber gasket 23 in order to fix products having width deviations. Plank 24 is designed to switch the limit switches 25 and 26 and is rigidly attached to the bed 15. The feed mechanism 6 of the product 19 consists of a pneumatic cylinder 27, on the stem of which a bracket 28 with spring-loaded levers 29 is fixed, and serves to feed the product 19 from the magazine 7 to the machining zone on the bed 15 along the guides 30. The bar 31, mounted on the bracket 28, controls the operation of the housing / 4032

One of the 1X switches J2 and 33, Tray 34 are prddnl yachek to remove obbtbotlennu. nzde.piy,

, Device 01: The track is scuffed.

The product is loaded into the mat 7, Drive 2 drives the spindle B with the contact roller 9 and, therefore, the abrasive tape 10, the Feed mechanism 6 using the spring-loaded lever op 29 attached to the rod of the pneumatic cylinder 27, through the bracket 28 delivers H ( The previous product is 19 of

Ti magazine 7 on the bed 15 of the mechanism for clamping the product along the guide 30. The plate 31 presses the limit switch 33, which gives a command to return the rod of the pneumatic cylinder 27 to

0 the initial position and at the same time the command to push the pneumatic cylinder 14, and with it the bed 15 with the product 19 upwards. When lifting the levers 18, moving along the bottom

the inclined surface of the fixed copiers 20, clamp the product. When the bed 15 is further raised, when the product 19 has not yet come in contact with the abrasive belt 10, the levers 1-8 exit to the upper straight line section of the copiers 20, expose the side surfaces of the product perpendicularly forming the contact roller 9. With further upward movement

the product 19, clamped by the levers 18, is pressed against the contact roller with an abrasive belt, the embedding process is carried out.

The contact time of the workpiece 19 with the contact roller 9 is set by a time relay. During all this time, bed 15 with the product 19 twilsets up. Plank 24 is on the limit switch 25,

It gives a command to extend the current of the pneumatic module 27 of the mechanism 6, podggschi the product 19, the new product is fed to the bed 15 of the mechanism 5 of the clamp. Served product

pushes the processed product out of the treatment area onto the inclined plane of the tray 34 along which it rolls into the container.
