Description

Technical Field

[0001] This utility model relates to a magnetic grinding and polishing device for die-cast parts. Background Technology

[0002] After die casting, the parts need to undergo surface treatments such as deburring and polishing. Traditional magnetic grinding and polishing equipment usually uses clamps to fix the workpiece.

[0003] However, existing fixtures are cumbersome to operate, which affects work efficiency, especially for mass-produced workpieces, where existing fixtures are insufficient to meet production demands. Therefore, it is necessary to design corresponding technical solutions to address these issues. Summary of the Invention

[0004] The purpose of this utility model is to provide a magnetic grinding and polishing device for die castings, which has a reasonable structure, is easy to clamp workpieces, helps to improve work efficiency, and is suitable for mass production.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a magnetic grinding and polishing device for die castings, including a magnetic grinding and polishing device body and a fixture. The magnetic grinding and polishing device body is provided with a grinding cavity, and the top of the magnetic grinding and polishing device body is provided with an opening communicating with the grinding cavity. Two side plates are provided at the opening, and the two side plates are arranged opposite to each other.

[0006] The clamp is disposed between two side plates and includes a flipping mechanism and a clamping mechanism. The flipping mechanism includes a flipping motor, a flipping shaft, and a flipping plate. A connecting plate is provided at the bottom of the flipping plate. The flipping shaft is fixedly inserted through the connecting plate, and both ends of the flipping shaft are rotatably connected to the two side plates respectively. One end of the flipping shaft passes through the side plate and is fixedly connected to the output shaft of the flipping motor. The flipping motor is fixedly connected to the side plate. The clamping mechanism is disposed at the top of the flipping plate and includes a clamping motor, a slide rail, and a lead screw. One end of the lead screw is fixedly connected to the output shaft of the clamping motor. Two clamping plates are slidably connected on the slide rail. The two clamping plates are threadedly connected to the lead screw through threaded holes, and the threads of the threaded holes of the two clamping plates are in opposite directions.

[0007] Preferably, flexible pads are provided on the inner sides of the two clamping plates facing each other.

[0008] Preferably, the flipping motor is fixedly connected to the side plate via a bracket.

[0010] Preferably, both the flipping motor and the clamping motor are provided with protective covers.

[0011] Preferably, both the flipping motor and the clamping motor are servo motors.

[0012] The advantages and beneficial effects of this utility model are as follows: It provides a magnetic grinding and polishing device for die castings, which has a reasonable structure. By setting a flipping mechanism, the clamping mechanism can be rotated through the flipping mechanism, so that the clamping mechanism can be moved out of the grinding chamber, which facilitates the operator to clamp the workpiece. In addition, when using the clamping mechanism, the operator only needs to place the workpiece between the two clamping plates, and the clamping motor drives the two clamping plates to move in opposite directions to achieve the clamping of the workpiece, which further improves the convenience of clamping the workpiece, helps to improve work efficiency, and is suitable for mass production.

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] The specific technical solution of this utility model is as follows:

[0017] like Figure 1 As shown, a magnetic grinding and polishing device for die castings includes a magnetic grinding and polishing device body 1 and a clamp 4. The magnetic grinding and polishing device body 1 is provided with a grinding cavity, and the top of the magnetic grinding and polishing device body is provided with an opening 2 communicating with the grinding cavity. Two side plates 3 are provided at the opening 2, and the two side plates 3 are arranged opposite to each other.

[0018] The clamp 4 is disposed between two side plates 3, and the clamp 4 includes a flipping mechanism and a clamping mechanism. The flipping mechanism includes a flipping motor 5, a flipping shaft 6, and a flipping plate 7. A connecting plate 8 is provided at the bottom of the flipping plate 7. The flipping shaft 6 is fixedly inserted through the connecting plate 8. Both ends of the flipping shaft 6 are rotatably connected to the two side plates 3 respectively, and one end of the flipping shaft 6 passes through the side plate 3 and is fixedly connected to the output shaft of the flipping motor 5. The flipping motor 5 is fixedly connected to the side plate 3. The clamping mechanism is disposed at the top of the flipping plate 7, and the clamping mechanism includes a clamping motor 9, a slide rail 10, and a lead screw 11. One end of the lead screw 11 is fixedly connected to the output shaft of the clamping motor 9. Two clamping plates 12 are slidably connected on the slide rail 10. The two clamping plates 12 are threadedly connected to the lead screw 11 through threaded holes, and the threads of the threaded holes of the two clamping plates 12 are opposite in direction.

[0019] Furthermore, flexible pads 13 are respectively provided on the inner sides of the two clamping plates 12 facing each other.

[0020] Furthermore, the flipping motor 5 is fixedly connected to the side plate 3 via the bracket 14.

[0021] Furthermore, the number of clamps 4 disposed between the two side plates 3 is two.

[0022] Furthermore, both the flipping motor 5 and the clamping motor 9 are provided with protective covers (not shown in the figure).

[0023] Furthermore, both the flipping motor 5 and the clamping motor 9 are servo motors.

[0024] When using the magnetic grinding and polishing device for die-cast parts according to this utility model:

[0025] The workpiece to be processed is clamped and fixed by a fixture. Specifically, the operator places the workpiece between two clamping plates 12. The clamping motor 9 rotates forward and drives the two clamping plates 12 to move towards each other. After the two clamping plates 12 move a set distance, they contact and clamp the workpiece through their respective connected flexible pads 13. Then, the flipping motor 5 drives the flipping plate 7 to rotate 180 degrees, so that the flipping plate 7 moves the clamping mechanism and the workpiece into the grinding chamber for polishing. After completion, the flipping motor 5 drives the flipping plate 7 to rotate 180 degrees again, so that the flipping plate 7 moves the clamping mechanism and the workpiece out of the grinding chamber. Finally, the clamping motor 9 rotates in reverse and drives the two clamping plates 12 to move away from each other, so that the two clamping plates 12 move their respective connected flexible pads 13 to release the workpiece. The operator then removes the polished workpiece.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
