Description

Technical Field

[0001] The utility model relates to the technical field of shaft part processing, in particular to a single-layer heat treatment bracket for a bicycle axle center. Background Technique

[0002] The bicycle axle center is a crucial component in a bicycle. It plays a key role in connecting and supporting various components. The front-wheel axle center and the rear-wheel axle center can ensure the smooth rotation of the wheels, making the cycling more stable. To facilitate the processing of the bicycle axle center, a single-layer heat treatment bracket for the bicycle axle center is required.

[0003] After retrieval, the Chinese patent publication number is: CN216972624U, which discloses a heat treatment shaft part support frame, including a bottom plate. A frame is fixedly installed at the top edge position of the bottom plate. A plurality of second clamping plates are fixedly installed inside the frame. A movable frame is slidably connected inside the frame. The clamping plates in the second clamping plates and the movable frame clamp a workpiece. A baffle is fixedly installed on one side of the frame. A driving mechanism is installed between the baffle and the movable frame. By rotating a knob, the movable frame moves to the left through the rotation of a threaded rod, so that the gap between the first clamping plate and the second clamping plate increases. Align the bottom of the workpiece with a groove, and the groove supports the bottom of the workpiece to keep the workpiece in a standing state. Rotate the knob in the reverse direction, so that the movable frame moves to the right along the frame, so that the first clamping plate and the second clamping plate respectively clamp both sides of the workpiece, making the workpiece heat more evenly during the heat treatment process. However, when the device is actually used, it drives the frame to fix the workpiece by rotating the knob. Since the device will be heated and cooled simultaneously with the workpiece during operation, the high temperature during operation will heat the knob, making it difficult to operate in a short time, thus reducing the convenience of the device.

Depending on the movement of the moving frame 5 along the positioning frame 4, the workpiece in the installation groove 3 can be fixed. Moreover, due to the interval between the first bevel gear 8 and the second bevel gear 9, the rotating rod 7 can be isolated from the frame body 1, thereby reducing the high temperature it bears during operation;

[0048] After stacking multiple devices up and down, relying on the elastic potential energy of the spring telescopic rod 201, the block 202 can be pushed to engage with the knob 6. During the assembly process, the movement of multiple moving frames 5 can be adjusted synchronously. The block 205 can be driven to move through the expansion, contraction and rotation of the telescopic plate 204.
