Problems solved by technology
[0006] In order to solve the above technical problems, the present invention provides a gear keyway fixing device to solve the problem that the existing gear keyway fixing device proposed in the above background technology can only be fixed from one direction, and the degree of fixing the gear is insufficient, so it cannot be fixed from one direction to the other. The gear is fixed at multiple angles, which will affect the precision and accuracy of the gear when pulling the key, and the operation and use of the keyway are also inconvenient.

The invention provides a gear broaching groove fixing device. The gear broaching groove fixing device comprises a main frame; a notch is formed in the middle of the front side of the main frame; guiderails are integrally arranged on the two sides of the front side of the main frame, and two sliding blocks are arranged at the tops of the two guide rails in a sliding mode; a pressing and fixing device is arranged on the front side of the main frame in a sliding manner; a transmission rod is rotationally arranged at the top of the main frame through a rotating shaft; a key broaching groove is formed in the notch in the front side of the main frame; by arranging a clamping and fixing device, the pressing and fixing device and the transmission rod, the gear can be fixed from multiple directions and angles, the gear is prevented from moving to the maximum extent, the transmission rod rotates and drives the pressing and fixing device to move towards the inner side, the gear is pressed and fixed to the front side of the main frame, a lead screw drives a connecting rod so as to drive the clamping device to retract, the gear is clamped in the upper direction and the lower direction throughgear grooves formed in a fixing block, the gear is prevented from rotating, and therefore deviation of the gear in the key broaching process is prevented.
Description
technical field [0001] The invention belongs to the technical field of gear production, and more particularly, particularly relates to a gear pull key groove fixing device. Background technique [0002] The shaft hole of the gear is usually provided with a keyway, and the keyway is used to install the key, which plays the role of transmitting torque. In the actual production process, the keyway is usually processed by broaching. The existing keyway processing device includes a frame, a broach, a traction mechanism arranged on the frame for pulling the broach, and an installation part arranged on the frame for installing the gear to be processed. The installation part has a cylindrical structure and is installed. The broach is provided with a broach groove for the broach to pass through. During processing, the gear to be processed is sleeved on the mounting part, and the traction mechanism drives the broach to move so that the broach is broached on the surface of the shaft h...
