Description

[0002] Chinese patent application number 202323267577.2 discloses a metal mold processing fixture. A drive motor can drive a bidirectional lead screw to rotate, which can drive two movable plates connected to it to move relative to each other. The movable plates drive the clamping plates to move relative to each other, thereby clamping and fixing the metal mold to be processed between the two clamping plates. It can clamp metal molds of various sizes. A servo motor can drive a drive gear to rotate, which drives a driven gear meshing with it to rotate. The driven gear drives a rotating shaft to rotate, thereby causing the metal mold clamped between the two clamping plates to flip.

[0003] However, when the device grinds the workpiece, because the grinding position is directly above the bidirectional lead screw, a large amount of debris falls onto the bidirectional lead screw. The debris generated by grinding is generally at a high temperature, and once the debris adheres to the surface of the bidirectional lead screw, it is difficult to clean, affecting the subsequent use of the bidirectional lead screw and making it impractical.

[0027] Working Principle: All electrical components mentioned in this application are externally connected to a power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions before use. During use, the servo motor 33 drives the bidirectional lead screw 35 to rotate. The bidirectional lead screw 35 drives the sliding plates 4 and 5 to move towards each other. The workpiece is clamped by the clamping plates 12 and 13. During the movement of the sliding plates 4 and 5, the spring inside the rotating roller 9 winds up the anti-scalding belt 10, keeping it taut. The anti-scalding belt 10 slowly winds up onto the rotating roller 9 as the sliding plates 4 and 5 move, making it parallel to the bidirectional lead screw 35. Then, the workpiece is polished by the grinding machine 3. During the process, the grinding direction of the workpiece is changed by rotating the knob 15. Some of the generated debris falls onto the anti-scalding belt 10, and the other part falls onto the perforated plate 11, which is then collected by the collection box 16. During the grinding process, the motor 19 is started, which drives the reciprocating screw 20 to rotate. The reciprocating screw 20 drives the slide plate 3 22 to move back and forth in the front and back direction. During the movement of the slide plate 3 22, the gear 29 meshes with the rack 23 and rotates. The gear 29 drives the connecting shaft 28 to rotate. The connecting shaft 28 drives the bevel gear 27 to rotate, which meshes with the bevel gear 26 and rotates. The bevel gear 26 drives the connecting shaft 25 and the brush 24 to rotate. The brush 24 rotates while adhering to the perforated plate 11 to clean the debris on the perforated plate 11, which is highly practical.
