Description

Technical Field

[0002] Grinding is a surface modification technology. It generally refers to a processing method that uses rough objects (such as sandpaper containing high-hardness particles) to change the physical properties of the material surface through friction. Its main purpose is to obtain a specific surface roughness. However, with the continuous development of society, the grinding process has become more automated through equipment.

Two clamping plates are arranged opposite each other to clamp the mechanical parts between them. The clamping plates are respectively mounted on two rotary drive devices, which can drive the mechanical parts to rotate under the action of the rotary drive devices. The rotary drive devices are respectively mounted on two clamping adjustment devices. The clamping adjustment devices are all mounted on the grinding table and can adjust the clamping distance between the two clamping plates. This utility model has high grinding efficiency, strong versatility, low noise, and good dust prevention effect.

[0027] By telescopically connecting two clamping blocks 15 to the front of the support block 14, and rotatably connecting an elastic clamping member between the two clamping blocks 15, the clamping device can clamp and fix plate-shaped workpieces and tubular workpieces, increasing the versatility of the device and eliminating the need to use different clamping devices to clamp and fix workpieces of different shapes.

[0028] Working principle: When clamping and fixing a plate-shaped workpiece, the workpiece is first placed on the pad 6. Then, the cylinder lifts the pad 6 so that the workpiece is between the two support blocks 14. Then, the drive motor 2 drives the screw 3 to rotate. The screw 3 drives the two side plates 8 to move relative to each other, so that the support blocks 14 and the clamping blocks 15 move relative to each other. The clamping blocks 15 make pre-contact with the two sides of the workpiece. The guide post 19 extends into the blind hole 27, so that the spring 28 is compressed. The limiting plate 22 and the connecting shaft 29 of the elastic clamping part are stored in the storage groove 20 until the support blocks 14 and the ends of the clamping blocks 15 abut together, thereby completing the clamping and fixing of the plate-shaped workpiece. Then the pad 6 is lowered, and the plate-shaped workpiece can be ground. After the top surface of the plate-shaped workpiece is ground, the drive motor 13 drives the clamping blocks 15 to flip so that the bottom surface of the workpiece faces up, and the bottom surface is ground.

[0029] When grinding a tubular workpiece, first rotate the rotating block 23. The rotating block 23 drives the threaded block 37 to rotate, causing the threaded block 37 to retract from the positioning hole 36 on the fixed plate 25 into the countersunk hole 35 in the fixed block 24. Then, drive the motor 26 to rotate the U-shaped plate 17, causing the two elastic clamping parts to face each other. Then, the rotating block 23 moves the threaded block 37 from the countersunk hole 35 into the corresponding positioning hole 36 on the fixed plate 25. Finally, one end of the tubular workpiece is sleeved onto one of the couplings. The outer edge of the coupling 29, the arc-shaped clamp 21 outside the coupling 29, extends and retracts under the action of the spring and the support rod 30, so that the arc-shaped clamp 21 abuts against the inside of the pipe fitting. Then the two side plates 8 move relative to each other, so that the coupling 29 on the other side is sleeved on the other end of the pipe fitting, so that the two ends of the pipe fitting abut against the two limiting plates 22. At the same time, the clamping block 15 abuts against the support block 14. Then the drive motor 3 18 drives the coupling 29 to rotate, and the coupling 29 drives the pipe fitting to rotate, so that the outside of the pipe fitting can be polished.
