Description

Technical Field

[0001] This utility model relates to a fixture, specifically a fixture for shaft machining, and belongs to the field of machining technology. Background Technology

[0002] Mechanical shafts are a type of connecting component, mainly used to transmit power and torque. For example, a mechanical shaft connected to a gear can transmit the rotational force of the gear to the outside, assisting mechanical components in their operation. In the processing of mechanical shafts, the shaft blank needs to be machined. Through machining, the mechanical shaft can be processed into different working dimensions.

[0003] In the machining of mechanical shafts, the shaft blank needs to be fixed inside a fixture. Fixing both sides of the mechanical shaft with the fixture ensures stability during machining. In existing technology, to facilitate the fixing of different types of fixed shafts, multiple sets of cylinders are set in the fixture to control the angle of the clamping components. When fixing an arc-shaped shaft, the angle of the clamping components can be adjusted to clamp at different positions and angles. However, the above structure requires back-and-forth adjustment of the position of the overall clamping components through fasteners during machining. After machining one section of the arc-shaped shaft, the fixture needs to be moved to fix other positions, requiring readjustment of the position and angle of the clamping components at the bottom. This cannot be adjusted quickly, and the friction between the fasteners will decrease under long-term adjustment and tightening, affecting the stable use of the clamping components. Therefore, we provide a fixture for shaft machining to solve the above problems. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This fixture for shaft machining, through the cooperation of a control mechanism, a threaded rod, and a moving block, allows the moving block to move by rotating the threaded rod. The moving block can then move within the machine frame, enabling rapid adjustment of the left and right positions of fixture one and fixture two. The control mechanism then controls the rotation of the connecting frame, allowing it to rotate circumferentially. The angle of the connecting frame can be adjusted according to different machining positions and fixed angles of the arc-shaped shaft. The entire adjustment process does not require repeated fixing of the clamping components, making it more convenient to use. It achieves the function of rapid adjustment of the angle of the clamping components, facilitating quick adjustment and fixing of different positions of the arc-shaped shaft.
