Description

Technical Field

[0001] The utility model relates to the technical field of chamfering machines, in particular to a pulley chamfering machine. Background Art

[0002] Chamfering refers to the process of cutting the edges and corners of a workpiece into a certain slope. In order to remove burrs on parts caused by machining and to facilitate the assembly of parts, chamfering is generally performed on parts. Chamfering machines are widely used in various processing fields and are very common. For example, they are also commonly used in the processing of pulleys.

[0003] After searching, a utility model patent with publication number (CN209830498U) specifically discloses a pulley chamfering tool, including a chamfering drill bit, which is detachably mounted on a chamfering operating frame, and the chamfering operating frame includes a first rigid rod, and the upper end of the first rigid rod is fixedly connected to one end of a first cross rod. In the prior art, most pulleys need to use a chamfering machine when chamfering. The chamfering machine needs to fix the pulley when chamfering, which is troublesome, and the production cost of the chamfering machine is relatively high. It is not very economical for chamfering a small number of pulleys. When using the utility model, the support ring can be supported on the pulley, and the chamfering drill bit can be inserted into the hole to be chamfered. The pressing block is pressed with the palm of one hand, and the gripping ring is held with the other hand. Then, the gripping ring is rotated with the axis of the chamfering drill bit as the center line, so that the chamfering drill bit is rotated to achieve the chamfering operation of the hole.

[0004] In the above patent, the chamfering operation of the hole is achieved only by supporting the pulley with a support ring and then driving the drill bit to rotate. The fixing effect is poor, and the pulley cannot be fixed stably, resulting in the movement of the pulley during the chamfering process, which will affect the normal chamfering work. The existing chamfering machine relies on the worker to support and press the device with one hand and then perform the chamfering work. This method is relatively laborious. When continuous chamfering is required, the worker will become fatigued, which will affect the chamfering efficiency and increase the labor intensity of the worker. It is less practical.

[0005] Therefore, it is necessary to invent a pulley chamfering machine to solve the above problems. Utility Model Content
