Description

Technical Field

[0001] The utility model relates to the technical field of mechanical part processing, in particular to an extrusion device for mechanical part processing. Background Technique

[0002] Publication No. CN218081495U discloses a fixing device for mechanical part processing, including a base. At corresponding positions on both sides of the top of the base, movable seats are slidably connected. Grooves are formed on the surfaces of the opposite sides of the movable seats. By setting the movable seats and the grooves, a limiting position can be provided for the processed mechanical parts. By setting the first limiting seat, the second limiting seat, the movable rod and the connecting plate, a transmission connection effect can be provided for the movement of the movable seats, and they can move simultaneously, facilitating the user to quickly fix multiple mechanical parts at the same time, improving the working efficiency of the fixing device. Then, by setting a spring to provide an elastic rebound effect, the sliding rod can slide inside the sliding sleeve, providing a limiting effect on the connecting plate. And by setting a baffle to limit the sliding rod, preventing the sliding rod from separating from the connecting plate when moving, but the following problems still exist in the actual use of this patent:

[0003] When the above device extrudes and fixes parts of different sizes, the clamping force is completely provided by the spring. Due to the telescopic characteristics of the spring, when the parts vibrate due to processing, it may cause the movable seat to drive the connecting plate to shake up and down through the movable rod, resulting in unstable fixing of the parts. In the existing clamping devices, the movement of the clamping parts is mostly controlled by threaded rods. However, when the clamping parts need to move a relatively large distance each time, it takes a long time to rotate the threaded rods, which is inconvenient to operate.

[0004] An extrusion device for mechanical part processing is proposed to solve the problems mentioned above. Content of the Utility Model
