Description

Technical Field

[0001] This utility model relates to the field of cutting devices, specifically a steering shaft cutting device. Background Technology

[0002] The automotive steering system is a crucial system in a vehicle. It typically consists of components such as the steering wheel, steering gear, steering column, steering shaft, and steering gear. To ensure the reliability and safety of the steering system, the connections between these components must be secure and reliable. The steering shaft is one of the most important components of the automotive steering system, serving as the intermediate shaft connecting the steering column and the steering gear. It not only connects and transmits torque but also effectively absorbs the axial and radial impact forces generated on the lower axle during vehicle bumps, preventing premature wear and abnormal noises, thereby improving driving comfort, handling, and safety.

[0003] Currently, the steering shaft needs to be pre-processed, that is, the raw material of the steering shaft needs to be cut. However, while cutting, the raw material of the steering shaft needs to be manually pulled. Now, a cutting device is provided to cut the steering shaft. Utility Model Content

[0004] The purpose of this invention is to provide a steering shaft cutting device to solve the problems mentioned in the background art, which has the advantage of moving the steering shaft while cutting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steering shaft cutting device, including a frame, a fixing member sleeved on the frame, a drive motor disposed in the middle of the frame, a first drive tooth connected to the drive motor, the first drive tooth meshing with two second drive teeth, a third drive tooth fixedly connected to the second drive tooth, and a fourth drive tooth meshing with the third drive tooth, one of the fourth drive teeth passing through a first drive assembly, and the other fourth drive tooth passing through a second drive assembly, the first drive assembly being connected to a cutting block.

[0006] By adopting the above technical solution, the drive motor is started to drive the first drive tooth to rotate, which in turn drives the two second drive teeth to rotate. The rotation of the second drive teeth drives the third drive tooth to rotate, which in turn drives the fourth drive tooth to rotate. The rotation of one of the fourth drive teeth drives the first drive assembly to move, which in turn drives the cutting block to move and cut the steering shaft. During this process, the other fourth drive tooth also rotates synchronously, driving the second drive assembly to rotate. The second drive assembly can drive the rotating shaft to move, so that after moving to one end length, the steering shaft is cut.

[0007] As a further embodiment of this utility model: the fixing member includes a vertical rod fixedly connected to the frame, a fixing rod fixedly connected to the side of the vertical rod, and a circular hole penetrating the fixing rod in the middle of the fixing rod.

[0008] By adopting the above technical solution, the original material of the steering shaft passes through the circular hole, and the circular hole plays a limiting role for the steering shaft.

[0009] As a further embodiment of this utility model: the first drive assembly includes a first drive shaft fixedly connected to the fourth drive tooth, and the first drive assembly also includes a mounting block fixedly connected to the frame. The mounting block is provided with a second drive shaft. The first drive shaft and the second drive shaft are integrally connected to a fixing block on opposite sides. A connecting shaft is provided between the two fixing blocks. A connecting rod is sleeved on the connecting shaft. One end of the connecting rod is rotatably connected to the cutting block.

[0010] By adopting the above technical solution, the fourth drive tooth drives the first drive shaft to rotate, which in turn drives the fixed block to rotate. The rotation of the fixed block drives the second drive shaft to rotate, which in turn drives the connecting rod to move. The movement of the connecting rod drives the cutting block to move, thereby allowing the cutting block to cut the steering shaft.

[0011] As a further improvement of this utility model: the side of the cut block is integrally connected to a limiting plate, and the frame is provided with a limiting groove for accommodating the middle part of the limiting plate.

[0012] By adopting the above technical solution, the limiting plate is always in the limiting groove, which restricts the cutting of the blocks.

[0013] As a further embodiment of this utility model: the second drive assembly includes a third drive shaft connected to another fourth drive tooth, the third drive shaft being sleeved with a first drive roller, and the frame being rotatably connected to a second drive roller located above the first drive roller.

[0014] By adopting the above technical solution, another fourth drive tooth drives the third drive shaft to rotate, which in turn drives the first drive roller to rotate. The first drive roller, in conjunction with the second drive roller, rotates to drive the steering shaft to move.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The start-up drive motor drives the first drive tooth to rotate, which in turn drives the two second drive teeth to rotate. The rotation of the second drive teeth drives the third drive tooth to rotate, which in turn drives the fourth drive tooth to rotate. The rotation of one of the fourth drive teeth drives the first drive assembly to move, which in turn drives the cutting block to move and cut the steering shaft. During this process, the other fourth drive tooth also rotates synchronously, driving the second drive assembly to rotate. The second drive assembly can drive the rotating shaft to move, and after moving to one end of the length, it cuts the steering shaft. Attached Figure Description
