Abstract

A transmission shaft end face tooth drill four-hole tooling, including a device body and a drill bit, a base is provided at the bottom of the device body, and a support plate is connected to the right side of the top of the base by welding; the chuck is connected to the The left side of the support plate, and the drive shaft is installed inside the chuck; the left side of the chuck is provided with two hydraulic seats at the front and rear, and the bottom of the hydraulic seat is connected to the top of the base by welding; the top of the hydraulic seat is passed The hydraulic rod is connected with a locking plate, and the locking plate is connected with the hydraulic rod by welding; the fixed support block is installed between the front and rear hydraulic seats, and the middle part of the transmission shaft is placed in the fixed groove of the fixed support block . The setting of the motor box of the present invention is beneficial to the centerline of the motor box and the centerline of the end face gear on the same axis, and the method of drilling four holes at the same time ensures the accuracy of the required drilling and prevents drilling errors. The situation of drilling deviation and drilling crooked occurs.

Description

technical field

[0001] The invention relates to the field of tooling and mechanical technology, in particular to a four-hole tooling for gear drilling on the end face of a transmission shaft. Background technique

[0002] Fixture refers to the process device used to quickly fasten the workpiece during processing to keep the machine tool, tool and workpiece in the correct relative position. That is to say, tooling and fixtures are indispensable parts of machining. Driven by the development of machine tool technology in the direction of high speed, high efficiency, precision, compound, intelligence and environmental protection, fixture technology is moving towards high precision, high efficiency, modularity, combination, general purpose, economic direction.

[0003] The designer found that the existing tooling for drilling four holes on the end face of the transmission shaft has poor positioning accuracy, and drilling errors, deviations, and deviations occur from time to time...
