The invention relates to belt grinding apparatus designs.

The purpose of the invention is to expand those LOOP1 of the device's axial capabilities by providing clamping using both a pneumatic cylinder and a p-drive actuator.

The drawing shows the proposed device.

The device includes a bar 1, a carriage 2 mounted on it. The lever 3 is connected to the carriage 2 through a guide roller (subframe) 4, which is installed in frame 5, rigidly connected via a bracket 6 to the rod 7 of the pneumatic cylinder 8. The bar 1 can rotate around axis aa. The presser iron 9 is installed on the lever 3. The roller 4 is installed in frame 5 and interacts with its sides, the presser surface of the iron 9. The given pressure exerted by the pneumatic cylinder 8 on the presser iron is installed by a pressure reducing valve 10, the pressure is turned on - by valve 11.

VcTpoHCTBj works in the same way.

When supplying air from / to the device, the valve 1I automatically switches the pneumatic cylinder 8 to the raised iron 9. V: this. The position of the workpiece is placed on the machine table and placed under the sanding belt. The pressure reducing valve 10 sets the required, set by the technological mode, the pressing force. The iron manually or other device move reciprocatingly over the processed surface. When the valve 11 is pressed (turned on), the cylinder 8 switches to the belt pressing and through the bracket 6 rotates the rod 1 around the axis A-A, together the frame 5 rotates in it. The frame 5 moves downwards, through the bearing 4 and the market -a 3 moves the iron 9 all the way through the pin belt into the workpiece. The magnitude of the force applied by the grinding belt to the iron 9 to be processed is proportional to the air pressure given by the pressure reducing valve 10.

A sanding belt, driven by an electric motor and pressed against a reciprocating iron, starts surface treatment of the part.

After processing is completed, valve 11 is released (turned off), the cylinder switches to reverse

the frame 5 moves upwards and through the sub-Wheel 4 and the lever 3 lifts the iron 9 above the workpiece. In this position, the part is unloaded from the machine and the processing cycle is repeated.

with the subsequent detail.

The guide roller 4, in contact with each of the ciopoH frame located parallel to the rod 1, provides the transmission of force as from. the rod 7 of the pneumatic cylinder 8, and from the lever 3 when manually acting on the iron 9, thereby ensuring the operation of the clamping device as in the mode of pneumatic pressure with ensuring pressure given by the pressure reducing valve
