Description

Technical Field

[0001] The utility model relates to the technical field of spare part clamping, in particular to a clamping device for spare part production. Background Technique

[0002] In the production and assembly process of mechanical equipment, some large equipment often requires a lot of small parts for cooperation and connection to obtain a certain relative position relationship between each component and form a whole. And various mechanical parts are small in size and different in shape. Therefore, during the production and processing of mechanical parts, clamping tools are needed for clamping and fixing.

[0003] Publication No.: CN219379856U provides a clamping device for mechanical spare part production that is easy to fix, belonging to the technical field of mechanical spare part production. It includes a base. A sliding groove is provided at the top of the base. A support plate is fixed to the lower wall of one side of the base. A motor is provided at the top of the support plate. One side of the motor is connected to a lead screw inserted into the sliding groove. Symmetrically slidably connected in the sliding groove are sliders through which the lead screw passes. An electric push rod is provided at the top of the slider. A first hollow block is fixed to the top of the left electric push rod. A moving plate is slidably connected in the first hollow block. A first rotating rod is rotatably connected to the side wall of the moving plate. The end of the first rotating rod is fixed to a first clamping plate. A second hollow block is fixed to the top of the right electric push rod. The utility model can flexibly clamp and fix mechanical spare parts of different sizes, avoiding clamping damage to mechanical spare parts; it is convenient to process mechanical spare parts at different angles without frequent disassembly and assembly, and the production efficiency is relatively high.

[0004] The applicant found that there are some deficiencies in use: The device clamps the spare parts through the clamping plate. However, when the spare parts are circular, such as bearing rings, the contact area between the clamping plate and both sides of the circular spare parts becomes smaller, and the clamping stability will be greatly reduced. Moreover, during processing, such as grinding and drilling, debris will be generated. The debris falls into the sliding groove and adheres to the thread, which will affect the transmission between the slider and the thread and is prone to jamming.

[0005] Therefore, the utility model designs a clamping device for spare part production to solve the problems existing in the prior art. Content of the Utility Model

A mounting block 10 is installed in the middle of the outer side wall of the rotating shaft 9. A first clamping plate 11 and a second clamping plate 12 are respectively installed on both sides of the mounting block 10. A telescopic dust-proof cloth 13 is connected between the two connecting plates 5. A dust suction box 14 is provided at one end of the top of the base 1. A plurality of dust suction ports 15 are provided at one end of the dust suction box 14 close to the groove 2. A driving mechanism 16 for adjusting the position of the dust suction box 14 is provided on the top of the base 1. A driving device is installed on one side of the bidirectional lead screw. One end of the rotating shaft is connected to the output end of the stepping motor. A connecting shaft is installed on one side of the U-shaped plate and is rotatably installed on the top plate. One side of the connecting shaft is connected to the output end of the servo motor, and the servo motor rotates forward and backward to avoid winding of the wires of the stepping motor. One end of the dust suction box is communicated with an industrial dust collector through a hose.

[0024] Please refer to Figures 1-4, in this embodiment: The driving mechanism 16 includes a long slot 161 which is opened at one end of the top of the base 1. A screw rod 162 rotatably installed with the base 1 is arranged in the long slot 161. A screw block 163 is slidably installed on the outer side wall of the screw rod 162 through threads. A connecting block 164 is installed on the top of the screw block 163. The connecting block 164 and the bottom of the dust collection box 14 are connected through a folding assembly 165.

[0025] Please refer to Figures 1-3 , in this embodiment: The folding assembly 165 includes a hinge frame 1651 which is installed on the top of the connecting block 164. A rotating block 1652 is installed in the middle of the outer side wall of the pin shaft of the hinge frame 1651.

[0026] Please refer to Figure 1 , in this embodiment: Rubber anti-slip pads are provided on the sides of the first clamping plate 11 and the second clamping plate 12 away from the mounting block 10.

[0027] Please refer to Figure 1 , in this embodiment: A guide rod fixedly connected to the base 1 is arranged in the groove 2, and the guide rod is slidably installed with the wire block 4.

[0028] Please refer to Figure 1 , in this embodiment: Telescopic rods are installed between the two sides of the top of the connecting plate 5 and the two sides of the bottom of the top plate 7.

[0029] Working principle: When the spare part is square, two clamping plates II 12 are used to clamp its two sides. When the spare part is circular, the rotating shaft 9 rotates 180 degrees, causing the mounting block 10 to drive the clamping plate I 11 and the clamping plate II 12 to rotate 180 degrees, and two clamping plates I 11 are used for clamping. This can increase the contact area with the circular spare part and improve the stability of clamping the circular part. The bidirectional lead screw 3 rotates to make the two screw blocks 4 approach each other, causing the connecting plate 5 to drive the top plate 7 to approach each other, so that the two clamping plates I 11 or the two clamping plates II 12 can approach each other to clamp the spare part. After clamping, the electric cylinder 6 drives the top plate 7 to move up and down to adjust the height of the spare part, which is convenient for workers of different heights to process. After adjusting the height, processing can be carried out. The telescopic dust-proof cloth 13 is used to prevent the chips generated during processing from falling into the groove 2 and accumulating on the bidirectional lead screw 3, avoiding jamming of the bidirectional lead screw 3 and the screw block 4. At the same time, the dust suction port 15 can collect a part of the chips, and the other part of the chips will fall on the top of the telescopic dust-proof cloth 13. The screw 162 drives the nut block 163 to move back and forth, which can adjust the position of the dust suction box 14, facilitating adjustment according to the processing position. When the processing is completed, the part is taken away, and then the two connecting plates 5 move away from each other to the maximum distance, stretching the telescopic dust-proof cloth 13. The hinge frame 1651 drives the rotating block 1652 to rotate 90 degrees, causing the dust suction box 14 to rotate to directly above the telescopic dust-proof cloth 13. The dust suction box 14 moves back and forth to collect the chips falling on the top of the telescopic dust-proof cloth 13, reducing the workload of the workers. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
