Description

Technical Field

[0001] The utility model relates to the technical field of gear shaft hole processing, in particular to a gear shaft hole punching and fixing device. Background Art

[0002] The gear shaft hole is a hole on the gear used to install on the shaft for transmission. Usually, the gear shaft hole is a circular hole in the center of the gear, and its diameter matches the diameter of the shaft to ensure that the gear can be properly installed on the shaft and rotate with it. When stamping the gear shaft hole, a corresponding fixture is required. The fixture can be used to clamp and limit the gear to be stamped, which facilitates stable stamping of the gear shaft hole.

[0003] When the gear shaft hole stamping and fixing devices currently on the market are used, the gear with the shaft hole to be processed is generally placed directly on top for processing. The existing gear shaft hole stamping and fixing devices can only process gears within a smaller size range and cannot limit the gear according to the actual size. Therefore, we need to propose improvements to the current gear shaft hole stamping and fixing devices. Utility Model Content

[0014] 1. The gear shaft hole punching and fixing device starts the motor to drive the first bevel gear set and the connecting rod connected to the output end to rotate synchronously. As the connecting rod rotates, the two extension seats on the outer side of the connecting rod can drive the extension seats to move synchronously outward along the active cavity and the installation cavity. At this time, the distance between the two moving extension seats gradually increases until the two extension seats are moved to a position matching the gear. The gear to be punched with the shaft hole can be placed above the support seat for processing. The two limit seats can be moved outward through the mutual cooperation of the first bevel gear set and the connecting rod, so that the gear shaft hole punching and fixing device is convenient for limiting gears of different sizes.

[0015] 2. The gear shaft hole stamping and fixing device has one end of the mounting seat overlapped with the inside of the mounting groove in the initial state, and the connected second bevel gear and the threaded rod are driven to rotate synchronously by turning the knob. As the threaded rod rotates, the mounting seat installed on the outer sleeve can extend outward along the inside of the mounting groove and move to a suitable position, so that the inner side of the mounting seat can fit against the edge of the gear shaft hole stamping device. By turning the knob and cooperating with the second bevel gear set and the threaded rod, the two mounting seats can be moved outward to the required installation width, thereby making the installation range of the gear shaft hole stamping and fixing device wider.
