Description

Technical Field

[0002] When processing the motor cover, a fixture is needed to position it to ensure the stability of the position during processing.

[0003] Utility model patent CN217194812 discloses a motor cover positioning processing fixture, which completes the initial positioning by placing the motor cover on a placement plate; then rotates the first handle to drive four arc-surface clamping blocks to contact the outer wall of the motor cover until the motor cover is clamped; then rotates the second handle to push the two arc-surface ladder blocks to slide outward until the arc surfaces of the two arc-surface ladder blocks contact the inner wall of the shaft avoidance hole on the motor cover.

[0004] The above structure has the following problems: four arc-surface clamping blocks are used to clamp the outer wall of the motor cover inward, and the arc surfaces of two arc-surface ladder blocks are used to clamp the inner wall of the shaft avoidance hole on the motor cover outward. The handle needs to be turned twice, and the clamping force is difficult to control. If the force is too small, the positioning effect of the motor cover will be poor, and if the force is too large, the motor cover may be deformed. Therefore, the positioning accuracy of the motor cover needs to be further improved.

[0005] Based on this, the utility model designs a motor cover processing fixture which is easy to position to solve the above problem. Utility Model Content
