Description
Technical Field
[0001] The utility model relates to the technical field of fixtures, and particularly relates to a fixture for processing die-castings. Background Art
[0002] A die-casting is a pressure-cast part. It is made by pouring molten metals such as copper, zinc, aluminum or aluminum alloy heated to a liquid state into the feeding port of a die-casting machine (die-casting press) equipped with a die-casting mold. Through the die-casting process of the die-casting press, copper, zinc, aluminum parts or aluminum alloy parts with shapes and sizes restricted by the mold are cast. Such parts are usually called die-castings. Die-castings may have different names in different places, such as die-cast parts, pressure-castings, etc. The production process of die-castings involves injecting molten or semi-molten metal into a metal mold at high speed and crystallizing under pressure to form a complete part.
[0003] Existing fixtures can usually clamp die-castings with regular shapes. However, there is instability when positioning and clamping irregular die-castings. And a positioning and clamping device that can stably position and clamp irregular die-castings usually cannot rotate them while clamping. Generally, it is necessary to manually disassemble and assemble die-castings frequently for position adjustment, which reduces the processing efficiency of die-castings. Therefore, a stable fixture for processing die-castings is needed. Summary of the Utility Model
[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a fixture for processing die-castings, which can solve the problem that a positioning and clamping device that can stably position and clamp irregular die-castings usually cannot rotate them while clamping, and generally requires manual frequent disassembly and assembly of die-castings for position adjustment, reducing the processing efficiency of die-castings.
[0005] To achieve the above object, the present utility model provides the following technical solutions: A fixture for processing die-castings, comprising a bottom plate, a clamping structure and a rotating structure.

[0021] Please refer to Figures 1-3, the present utility model provides a technical solution: a fixture for processing die-castings, including a bottom plate 1, a clamping structure and a rotating structure. The clamping structure includes a fixed clamping plate 2, a first clamping block 3, a first rotating member 4, a clamping column 5, a spring 6, a fixed block 7, a push rod motor 8, a push rod 9, a sliding clamping plate 10, a second clamping block 18 and a second rotating member 19. The fixed clamping plate 2 is fixedly connected to the top of the bottom plate 1. The first clamping block 3 is rotatably connected to the surface of the fixed clamping plate 2. The first rotating member 4 is fixedly connected to the first clamping block 3. The first rotating member 4 is rotatably connected to the inside of the fixed clamping plate 2. The fixed block 7 is fixedly connected to the inside of the first clamping block 3. The clamping column 5 is slidably connected to the inside of the first clamping block 3. The spring 6 is fixedly connected between the clamping column 5 and the fixed block 7. The number of the clamping columns 5, the springs 6 and the fixed blocks 7 is multiple and they are evenly distributed on the surface of the first clamping block 3. The push rod motor 8 is fixedly connected to the top of the bottom plate 1. The push rod 9 is arranged at the output end of the push rod motor 8. The sliding clamping plate 10 is slidably connected to the top of the bottom plate 1. The sliding clamping plate 10 is fixedly connected to the push rod 9. The second rotating member 19 is rotatably connected to the inside of the sliding clamping plate 10. The second clamping block 18 is fixedly connected to the second rotating member 19. The structure of the second clamping block 18 is exactly the same as that of the first clamping block 3. When clamping a die-casting, place the die-casting between the first clamping block 3 and the second clamping block 18. Start the push rod motor 8 to push the sliding clamping plate 10 to move and drive the second clamping block 18 to move. The positions of the first clamping block 3 and the second clamping block 18 gradually approach and clamp the die-casting in the middle. When the clamping column 5 touches the die-casting, it will cause the spring 6 to contract and move towards the inside of the first clamping block 3. The displacement distances of different clamping columns 5 are different. Through the action of multiple clamping columns 5, stable clamping of irregular die-castings can be achieved, increasing the clamping stability and having a wider range of use.
[0022] Furthermore, the rotating structure includes a mounting plate 12, a motor 13, a first gear 14, a second gear 15, a rotating rod 16 and a rectangular rod 17. The mounting plate 12 is fixedly connected to the top of the bottom plate 1. The motor 13 is fixedly connected to the mounting plate 12. The first gear 14 is fixedly connected to the output shaft of the motor 13. The second gear 15 is meshed with the first gear 14. The rotating rod 16 is fixedly connected to the second gear 15. The rotating rod 16 is rotatably connected to the mounting plate 12. The rectangular rod 17 is slidably connected inside the rotating rod 16 and the second gear 15. The rectangular rod 17 is fixedly connected to the second clamping block 18. During the clamping and positioning process of the die-casting part, the movement of the sliding clamping plate 10 drives the rectangular rod 17 to move inside the rotating rod 16 and the mounting plate 12. After the die-casting part is clamped and positioned, the motor 13 is started to drive the first gear 14 and the second gear 15 to rotate, and drive the rotating rod 16 and the rectangular rod 17 to rotate. Since the rectangular rod 17 is fixedly connected to the second clamping block 18, the second clamping block 18 will be driven to rotate while the rectangular rod 17 rotates, so as to realize the rotation of the die-casting part during the clamping and positioning process. The function is more comprehensive and the use is more convenient. Through the cooperation of the above structures, the problem that a stable positioning and clamping device for irregular die-casting parts usually cannot clamp and rotate them at the same time, and generally requires manual frequent disassembly and assembly of the die-casting parts for position adjustment, reducing the processing efficiency of the die-casting parts, is solved.
[0023] Secondly, a rectangular groove adapted to the rectangular rod 17 is opened inside the rotating rod 16. A receiving groove 20 is opened on the surface of the second rotating member 19. A slot through which the rectangular rod 17 can pass is opened on the surface of the mounting plate 12. A limiting groove 11 for limiting the movement of the sliding clamping plate 10 is opened on the top of the bottom plate 1.
[0024] Working principle: When clamping the die-casting part, place the die-casting part between the first clamping block 3 and the second clamping block 18. Start the push rod motor 8 to push the sliding clamping plate 10 to move and drive the second clamping block 18 to move. The positions of the first clamping block 3 and the second clamping block 18 gradually approach and clamp the die-casting part in the middle. When the clamping column 5 touches the die-casting part, it will cause the spring 6 to contract and move into the first clamping block 3. The displacement distances of different clamping columns 5 are different. The stable clamping of the irregular die-casting part can be realized through the action of multiple clamping columns 5. During the clamping and positioning process of the die-casting part, the movement of the sliding clamping plate 10 drives the rectangular rod 17 to move inside the rotating rod 16 and the mounting plate 12. After the die-casting part is clamped and positioned, the motor 13 is started to drive the first gear 14 and the second gear 15 to rotate, and drive the rotating rod 16 and the rectangular rod 17 to rotate. Since the rectangular rod 17 is fixedly connected to the second clamping block 18, the second clamping block 18 will be driven to rotate while the rectangular rod 17 rotates, so as to realize the rotation of the die-casting part during the clamping and positioning process.
[0025] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
