Description

Technical Field

[0001] The utility model relates to the technical field of trimming machines, in particular to a trimming machine for producing mechanical seals. Background Art

[0002] Seals are materials or parts that prevent fluids or solid particles from leaking between adjacent joint surfaces and prevent foreign matter such as dust and moisture from invading the internal parts of machinery and equipment. After the seals are produced, most of them have a lot of burrs on the outer surface, which need to be polished. However, the existing trimming devices have certain problems when used and still need to be continuously improved;

[0003] For example, a trimming machine for mechanical seal production disclosed in the utility model with authorization announcement number CN216298809U includes an operating platform, which also includes a cleaning structure and a fixing structure. Support legs are arranged around the bottom of the operating platform, and a water tank is arranged at one end of the top of the operating platform. Support plates are arranged on both sides of the top of the operating platform, a top plate is arranged on the top of the support plate, and a cylinder is arranged at the central position of the bottom of the top plate, telescopic rods are arranged on both sides of the bottom of the top plate, a fixing plate is arranged at the bottom of the cylinder, and a motor box is arranged on both sides of the bottom of the fixing plate, a driving motor is arranged inside the motor box, and a grinding wheel is arranged at the output end of the driving motor. Through the cylinder and the grinding wheel, seals of different heights can be processed, thereby improving the practicability of the device.

[0004] When the device is working, the mechanical seal is first limited and fixed, and then the mechanical seal fixed at the upper limit of the fixed structure can be trimmed. Since there is only one set of fixed structures for limiting and fixing the mechanical seal on the operating platform, it needs to be removed manually after trimming, and the debris on its surface needs to be cleaned. Then, the next mechanical seal to be trimmed is placed on the fixed structure before the subsequent mechanical seal trimming work can be carried out, which results in low working efficiency and poor continuity of this setting method, affecting work efficiency.
