Technical Field

[0001] This utility model relates to the technical field of end chamfering of automotive steering torsion bars, and in particular to an end chamfering device for automotive steering torsion bars. Background Technology

[0002] The steering torsion bar is a key elastic element in the steering system. Its main function is to transmit steering force through elastic deformation and buffer road impacts, while also helping to restore the steering wheel to the center position.

[0003] In existing automotive steering torsion bar end chamfering devices, such as the pipe end chamfering device disclosed in utility model patent application number 202221706850.X, the utility model uses a pull rod to slide inside the adjusting frame, causing the insert rod to slide inside the adjusting frame, so that the insert rod is pulled out from the slot inside the connecting plate, and then the insert bracket is pulled out from the slot inside the mounting bracket, thereby allowing the mounting bracket and the cutting tool inside the mounting bracket to be removed and replaced.

[0004] However, during the chamfering process at the end of the automotive steering torsion bar, the material needs to be disassembled and re-fixed after each processing step, which reduces processing efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automotive steering torsion bar end chamfering device that automatically fixes and chamfers materials during the chamfering process of automotive steering torsion bars by setting a transport mechanism and a limiting mechanism, thereby improving processing efficiency.

[0006] This utility model discloses a chamfering device for the end of an automotive steering torsion bar, comprising a transport mechanism; and further comprising a limiting mechanism, three sets of clamping mechanisms, a rotating mechanism, a supporting mechanism, and a chamfering mechanism. The limiting mechanism is mounted on the transport mechanism, the three sets of clamping mechanisms are mounted on the limiting mechanism, the rotating mechanism is mounted on the limiting mechanism, the supporting mechanism is mounted on the rotating mechanism, and the chamfering mechanism is mounted on the rotating mechanism.

[0007] The transport mechanism transports materials, the limiting mechanism limits them, the clamping mechanism clamps them, the rotating mechanism rotates them, the supporting mechanism supports them, and the chamfering mechanism chamfers them. By opening the transport mechanism to transport materials, opening the limiting mechanism to limit them, opening the clamping mechanism to clamp them, opening the supporting mechanism to support them, opening the rotating mechanism to rotate them, and opening the chamfering mechanism to chamfer them, the materials can be automatically fixed and chamfered during the chamfering process of the end of the car steering torsion bar, thus improving processing efficiency.

The two sets of sprocket shafts are rotatably mounted on the base frame, and the chain conveyor belt is mounted on the two sets of sprocket shafts. The motor is mounted on the right end of the base frame, and the output end of the motor is connected to the input end of one set of sprocket shafts. By turning on the motor, the sprocket shafts are driven to rotate, and the rotation of the sprocket shafts drives the chain conveyor belt to rotate, thus transporting the materials.

[0009] Preferably, the limiting mechanism includes two sets of movable frames, a bidirectional lead screw, and a second motor. The two sets of movable frames are slidably mounted on the base frame, and the bidirectional lead screw is rotatably mounted on the base frame. The bidirectional lead screw is threadedly engaged with both sets of movable frames. The second motor is mounted on the left end of the base frame, and the output end of the second motor is connected to the input end of the bidirectional lead screw. By turning on the second motor, the bidirectional lead screw is driven to rotate. As the bidirectional lead screw rotates, it engages with the movable frames threadedly, causing the movable frames to move and limit the material movement.

[0010] Preferably, the clamping mechanism includes a cylinder and a clamping plate. The cylinder is mounted on a movable frame, and the clamping plate is mounted on the cylinder. The clamping plate is moved by opening the cylinder to clamp the material.

[0012] Preferably, the support mechanism includes a rotating ring, three sets of support arms, and three sets of rollers. The rotating ring is rotatably mounted on the movable frame, and the three sets of support arms are rotatably mounted on the rotating ring via spiral springs. Each set of support arms is rotatably mounted with a set of rollers. The support arms support the rollers to support and limit the material.

The toothed ring is installed inside the movable frame, the bevel gear is rotatably installed on the rotating frame, and the bevel gear meshes with the toothed ring.
