Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a drilling and tapping fixture for a driving wheel shaft. Background Technique

[0002] The drive shaft is an important component for transmitting power in the automotive transmission system. Its function is to transmit the power of the engine to the wheels together with the gearbox and the drive axle, enabling the vehicle to generate driving force. When manufacturing the drive shaft, various machining operations on the drive shaft are involved according to design requirements, such as machining external splines on the drive shaft or drilling holes on the end face of the drive shaft. During the drilling and tapping process of the drive shaft, a fixture is required to assist in fixing the drive shaft to facilitate the drilling work.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN206047151U discloses a shaft drilling tooling, including a workbench and a clamping mechanism. The shaft drilling fixture further includes a support seat suspended above the workbench. A notch penetrating in the vertical direction is formed in the support seat. The clamping mechanism includes a first clamping block fixed on the first side wall of the notch and a second clamping block passing through from the second side wall until horizontally passing out from the side of the support seat. The second clamping block can move closer to or away from the first clamping block. Opposite ends of the first clamping block and the second clamping block form a first limiting groove and a second limiting groove respectively. The positions of the first limiting groove and the second limiting groove correspond. The first limiting groove extends from the end face of the first clamping block towards the direction away from the second clamping block and gradually decreases in width to form a V shape. The second limiting groove extends from the end face of the second clamping block towards the direction away from the first clamping block and gradually decreases in width to form a V shape.
