The invention discloses a fixing structure for gear hub three-groove milling. Through the fixing structure, the technical problems that an existing gear hub fixing fixture is in a mechanical hard connection mode and cannot be adjusted, accordingly, the transmission precision of a gear hub is affected, and the product quality is reduced are solved. The fixing structure comprises a mandrel, a nut, an open gasket, an elastic damping block, a tooth-shaped positioning block and a positioning plate; the mandrel is provided with a gear hub fixing part, and the position, on one side of the gear hub fixing part, of the mandrel is in threaded connection with the nut which is used for fixing a to-be-machined gear hub; the open gasket is arranged between the gear hub fixing part and the nut; the position, on the other side of the gear hub fixing part, of the mandrel is provided with a positioning boss; the position groove transversely penetrates through the middle of the positioning boss, and thebottom of the positioning groove is provided with the elastic damping block; and the elastic damping block is provided with the tooth-shaped positioning block. Through the fixing structure, the accuracy of transmission between the gear hub and other parts can be effectively ensured, and the quality of a synchronizer and other devices is improved.
Description
technical field [0001] The invention belongs to the production field of metal mechanical parts, and in particular relates to a fixing structure for milling three grooves of a gear hub. Background technique [0002] The gear hub is one of the necessary parts in the structure of the synchronizer and other devices. It is usually a three-slot structure, and the outer ring has teeth. The gear hub is an important part of the synchronizer to adjust the speed and make the gears engage with each other. It is the key to the rapid shifting of the car, so its machining accuracy is also high. [0003] During the processing of the gear hub, the gear hub needs to be fixedly installed and positioned on the mandrel, and then the corresponding tool is used to mill the slot; in this process, the fixed installation and positioning of the gear hub is usually a universal type The structure, that is, a set of fixing fixtures are used for different batches of gear hubs of the same model, and they ...
