Description

Transmission shaft straightening device

Technical Field

The utility model belongs to the field of transmission shaft processing, in particular to a transmission shaft straightening device.

Background Art

The drive shaft is an important component for transmitting power in the automobile transmission system. Its function is to transmit the power of the engine to the wheels together with the gearbox and drive axle to generate driving force for the car. The drive shaft is a rotating body with high speed and few supports, so its dynamic balance is very important. The role of the dynamic shaft in the car is very important, so the quality of the drive shaft needs to be strictly controlled. During the production and processing of the drive shaft, the slender structure of the drive shaft itself will make it easy to cause it to be crooked due to various reasons, so it is often necessary to use a straightening device to straighten the drive shaft;

After searching, the Chinese patent with announcement number: CN219520266U discloses a transmission shaft straightening device, including a support base, support columns are fixedly installed at the four corners of the top of the support base, and a bearing platform is fixedly arranged on the top of the support column. A mounting groove is opened on the top of the bearing platform, and a No. 1 screw is rotatably arranged at the left and right ends of the interior of the mounting groove through a bearing, and mounting seats are symmetrically arranged on the outer surfaces of the No. 1 screw, and an automatic clamping mechanism is arranged on the top of the mounting seat, and an L-shaped support frame is fixedly installed on the front side of the top of the bearing platform, and an electric guide rail is fixedly installed on the rear side of the transverse end of the L-shaped support frame. The automatic clamping mechanism arranged in the transmission shaft straightening device achieves the purpose of automatically clamping the transmission shaft by the device, which is convenient for the staff to operate, improves the staff's work efficiency, and ensures the processing progress of the transmission shaft.

In this patent, after the drive shaft is fixed by the automatic clamping mechanism, the straightener can only straighten the bends in one direction of the drive shaft. However, the actual drive shaft may be bent in multiple directions. Therefore, the staff is required to manually rotate and adjust the drive shaft multiple times to straighten the drive shaft, which increases the labor intensity of the staff and reduces the straightening efficiency.

In summary, the utility model therefore provides a transmission shaft straightening device to solve the above-mentioned problems.
