Description

Technical Field

[0001] The utility model belongs to the technical field of gear handle machining and positioning, and relates to a gear handle machining and rapid positioning device. Background Art

[0002] A gear shank, also commonly known as a gear shaft or gear handle, is a component in a mechanical device that is primarily used to connect a gear to a drive source, such as an electric motor or a manually operated lever. Its primary function is to transmit torque through rotation, thereby rotating the gear. The design of a gear shank usually takes into account multiple factors, including material selection, size and shape, and how it fits with the gear and other mechanical parts. Gear shanks are heavy and require grinding during manufacturing. During the grinding process of the gear shank, if it cannot be quickly and accurately positioned, a series of problems will arise.

[0003] During the grinding process, accurate positioning is the key to ensuring the quality and performance of the gear shank. If the positioning is inaccurate, the grinding result may not meet the design requirements. For example, key parameters such as the gear tooth shape and pitch may deviate, which will directly affect the transmission efficiency and life of the gear.

[0004] Without the support of rapid positioning, operators may need to rely on more manual operations and experience to judge the position, which not only increases the difficulty of operation, but also may lead to operational errors and even safety accidents, such as collision between tools and workpieces, and workpiece falling off.

[0005] To sum up, the inability to quickly position the gear shank during its grinding process will not only affect production efficiency and processing accuracy, but also increase operating difficulty and processing risks, and will also have an adverse effect on the service life and utilization rate of the equipment. Therefore, there is an urgent need for a gear shank processing rapid positioning device to solve the above problems. Utility Model Content
