Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a gear processing fixture. Background Art

[0002] Gear machining fixtures are used to fix and clamp gear workpieces so that they can maintain a stable and accurate position during machining. This helps ensure the accuracy and quality of gear machining. Common gear machining fixtures include chucks, fixtures, and collets. In gear machining, the selection and design of fixtures are crucial to machining accuracy and efficiency. The appropriate fixture type is usually selected based on the size, shape, and machining requirements of the gear.

[0003] When using existing gear processing fixtures, they usually clamp and fix the outer side or both ends of the gear. If the clamping force is too large or uneven, it may cause local deformation of the gear workpiece, affecting the geometric accuracy and final rotational accuracy of the gear. For gears that need to switch processing parts multiple times, it is necessary to release the clamping of the gear multiple times to allow the part blocked by the clamping mechanism in the previous step to leak out before processing. There are certain limitations when using it. At the same time, the existing gear processing fixture is not convenient for making the gear rotate when clamping the gear, which adds certain inconveniences. Utility Model Content

[0006] Preferably, the number of the first connecting rods, the second connecting rods and the clamping blocks is the same.

[0007] Preferably, an anti-slip pad is provided on the outer surface of the clamping block.

[0008] Preferably, the driving mechanism is a motor arranged outside the vertical pole, and the output end of the motor is connected to the end of the column to drive the column to rotate.

[0010] Preferably, a limiting plate is provided on the side wall of the clamping block located inside the cavity.

[0011] The beneficial effects of the utility model are:

[0012] When the utility model is in use, the gear is sleeved on the outside of the column, and the driving mechanism is started to extend the output end of the driving mechanism. At this time, the first connecting rod and the second connecting rod rotate at the same time and push the clamping block to clamp the inner hole of the gear, thereby achieving the purpose of clamping the inner hole of the gear and avoiding the problem of affecting the geometric accuracy and final rotation accuracy of the gear when clamping the outer wall of the gear.
