Description

Technical Field

[0001] The utility model relates to the technical field of MIM related accessories, and particularly relates to a grinding and processing fixing jig for special-shaped structure products. Background Art

[0002] During the production process, due to the presence of two gate positions on the injection blank of the special-shaped structure product, the automatic punching method cannot ensure 100% flat cutting. There will be over-cutting or excessive residue, and manual reprocessing is still required. At the same time, there are unstable factors in manual trimming, and the quality stability and appearance consistency cannot be guaranteed; due to the unstable situation of punching the gate, it cannot well meet the requirements of customers, affecting the product quality, and it is difficult to repair the sintered product, with high costs, which is not conducive to the smooth progress of production.

[0003] Based on the above situation, a grinding and processing fixing jig for special-shaped structure products has been developed and designed. Summary of the Utility Model

[0028] Embodiment 1

[0029] Appendix Figures 1-3 This is a grinding and fixing fixture for a special-shaped structure product according to the present utility model, including a fixing base 1, a pressing plate 2 and a dowel pin 3; the outer shapes of the fixing base 1 and the pressing plate 2 are both diamond-shaped, which can better cooperate with the punching tooling to expose the gate of the product to be processed;

[0030] Both the fixed seat 1 and the pressing plate 2 are respectively provided with mounting holes 4 for installing fasteners, which facilitates the fixing and disassembly of the two and improves the disassembly and assembly efficiency.

[0031] The pressing plates 2 are respectively installed at both ends of the fixed seat 1, and the pressing plates 2 play a role in fixing and limiting, ensuring that the product will not move within the fixed seat 1.

[0032] A fixing groove 5 for placing the product is provided in the middle of the fixed seat 1. The fixing groove 5 is arranged in a stepped manner, which plays a role in accurately positioning and placing the product when placing the product, so that the product will not be disordered.

[0033] The pressing plate 2 is also provided with through holes 6 for installing the insert pins 3; the number of through holes 6 on the pressing plate 2 is at least 2, which is set according to the number of holes on the product with a special-shaped structure. Two through holes can pass through two insert pins 3, ensuring that all products with special-shaped structures within the fixed seat 1 are fixedly installed in the fixing groove 5.

[0034] The insert pins 3 penetrate through the pressing plate 2 at one end of the fixed seat 1, pass through the fixing groove 5, and then extend through the pressing plate 2 at the other end, so as to fix the product with a special-shaped structure and prevent it from shaking during processing, resulting in inconsistent appearance.

[0035] In order to better cooperate with the punching tooling and fix the entire fixture, a magnetic adsorption device is provided at the bottom of the fixed seat 1, which can ensure that the entire fixture is adsorbed and fixed on the grinding machine disk.

[0036] During specific use, first clean the grinding and fixing fixture of the present application, place the sintered product with a special-shaped structure into the fixing groove 5 of the fixed seat 1, use the insert pins 3 and the pressing plate 2 to fix the product with a special-shaped structure, then place the entire grinding and fixing fixture with the fixed product on a clean grinding machine disk, and after adding magnetic fixation, perform the treatment on the grinding gate position.

[0037] For the grinding and fixing fixture for products with special-shaped structures of the present application, through the combined use of the fixed seat 1, the pressing plate 2 and the insert pins 3, the product with a special-shaped structure is fixed and placed through the fixture, so that the gate positions of the products are uniformly placed outside. After punching by the punching tooling, grinding and processing are carried out, fundamentally solving the problem that the instability of the punching tooling causes the gate of the product to be high or low, making the gate position size of the product stable and the appearance consistent, effectively improving the yield rate of the product appearance, and at the same time reducing the steps of manually reprocessing the gate. Although the grinding process is increased, the quality stability of the product is ensured, and the dimensional and appearance yield rates of the product are significantly improved, meeting the requirements of customers and being beneficial to the better development of the enterprise.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
