Description

Technical Field

[0001] The utility model belongs to the technical field of parts processing, in particular to an auxiliary tooling for grinding parts made of silicon nitride. Background Art

[0002] Silicon nitride parts refer to functional parts made of silicon nitride material, and silicon nitride parts have excellent high temperature resistance, corrosion resistance and high hardness characteristics; in order to increase the smoothness of the surface of silicon nitride parts, staff need to operate the grinding equipment to grind the surface of silicon nitride parts, and in order to increase the stability of silicon nitride parts during grinding, clamping auxiliary tooling is needed to position the silicon nitride parts, so as to better control the grinding equipment to grind the silicon nitride parts.

[0003] After searching, a patent document with patent announcement number CN220863673U discloses an auxiliary tooling for machining mechanical parts, including: a frame; a transverse telescope, which is fixedly mounted on one side of the frame and is used for telescoping; a rotating device, which is fixedly mounted on the front end of the transverse telescope; and a clamping device, which is fixedly mounted on the front side of the rotating device. The above scheme sets a transverse moving device and a rotating device, so that when machining parts, one side can be clamped by the structure, and then only the rotating device needs to be started when the angle needs to be changed. Then the hydraulic lifter and the support plate will assist the above device to perform auxiliary clamping, making the device more stable, so that there will be no deviation during grinding. When replacing, only the clamping device needs to be loosened, and the part can be rotated between the push plates to a suitable angle for clamping. The above structure greatly facilitates the machining of parts without removing the parts for clamping.

[0004] However, it still has the following disadvantages in actual use:

[0005] The above-mentioned auxiliary tooling for machining mechanical parts has a lateral moving device connected to both the upper and lower sides of the frame, a hydraulic lifter connected to one side of the lateral moving device, and a support plate connected to one end of the hydraulic lifter. The lateral moving device is controlled to adjust the position of the support plate, and the hydraulic lifter is controlled to adjust the distance between the support plate and the workpiece, so as to assist in positioning the workpiece and prevent the workpiece from shifting during the grinding process. However, the support plate can only assist in positioning the workpiece, which is not convenient for grinding the workpiece in the rotating process, and the grinding assembly needs to be controlled separately to grind the workpiece, resulting in the single functionality of the above-mentioned auxiliary tooling for machining mechanical parts.

[0006] 2. The above-mentioned auxiliary tooling for machining mechanical parts has a transverse expander connected to one side of the frame, a rotating device connected to the front end of the transverse expander, and a clamping assembly connected to the front side of the rotating device. The clamping assembly is operated to clamp the workpiece, and then the rotating device is conveniently operated to rotate and adjust the orientation of the workpiece, and different surfaces of the workpiece are ground. However, the clamping assembly blocks the machining surface of the workpiece during the process of clamping the workpiece, and the workpiece needs to be locked again, which complicates the operation steps and increases the workload of the staff.

[0007] To this end, we provide an auxiliary tooling for grinding silicon nitride parts to solve the above problems. Utility Model Content
