Description

Technical Field

[0001] The utility model belongs to the technical field of bushing processing, in particular to a bushing cutting device. Background Art

[0002] Bushing processing usually refers to the process of processing bearings, shafts and other parts in the field of mechanical manufacturing. A bushing is a component that is sleeved on a shaft or in a seat hole to reduce friction and wear and improve the durability of parts. Bushing processing is a common process in manufacturing, and its quality is directly related to the performance and life of mechanical parts.

[0003] A Chinese patent with publication number CN107695692A discloses a bushing processing equipment, including a base, a base top, a planetary gear mechanism, a chassis, a hollow disk, a drilling mechanism, a cutting mechanism, and a transmission mechanism. The planetary gear mechanism is arranged on the base, the drilling mechanism is arranged on the base top, the chassis is arranged on the planetary frame, the chassis top is rotatably connected to the base top, the hollow disk is rotatably connected to the drilling mechanism, one end of the transmission mechanism is connected to the hollow disk, and the other end is connected to the cutting mechanism. When the drilling mechanism drills a hole in the bushing, it drives the cutting mechanism to cut the bushing. The device has multiple cutting mechanisms to cut the bushing at the same time, which can play a clamping role. The planetary gear mechanism can enable the cutting mechanism to cut annular grooves on the bushing. The device can drill holes and cut annular grooves on the bushing at the same time, and does not require a clamping part, so the bar material can be fully processed to reduce material waste.

[0004] As mentioned above, the patent provides a bushing processing equipment, which eliminates the clamping part and adopts a multi-cutting mechanism to cut and clamp the bushing. This method is likely to cause the bushing to deviate sideways, and multiple cutting components cut at the same time, which is likely to cause the temperature to rise instantly during cutting. Overheating will cause deformation of the cutting head and the cutting surface of the bushing, resulting in a significant impact on the processing accuracy. In addition, each cutting component needs to be equipped with a working motor. Although this can reduce material waste, the processing cost is significantly increased and the adaptability of use is not high.

[0005] Therefore, a bushing cutting device is proposed to solve the above problems. Utility Model Content
