Description

Technical Field

[0001] The utility model belongs to the technical field of spring processing equipment, in particular to a spring grinding and chamfering device. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force and return to their original shape after the external force is removed. Most springs need to have their ends chamfered after production.

[0003] After searching, the patent announcement number CN212762574U discloses a spring grinding and chamfering device, which belongs to the field of chamfering devices, including a base, a grinder is fixedly installed on one end of the upper end surface of the base, a slide groove is opened on the other side of the upper end surface of the base, and a threaded shaft is fixedly installed on both ends of the slide groove through a bearing, and a slider is threadedly sleeved on both ends of the middle side surface of the threaded shaft. The upper end of the slider is slidably connected to a fixed seat, and a placement groove is opened on the upper end surface of the fixed seat. A clamping plate is fixedly installed on one side of the lower end surface of the placement groove. A groove is opened on one side of the upper end surface of the base, and a baffle is slidably connected inside the groove. An elastic clamping strip is fixedly installed on the lower end surface of the baffle, and the elastic clamping strip is slidably connected to the inside of the clamping slot opened on the lower end surface of the groove. The spring grinding and chamfering device can control the movement of the fixed seat under the action of the slider by rotating the threaded shaft, so that the spring can be ground and chamfered, and the chamfering is uniform, which improves the use effect.

[0004] When the existing spring grinding and chamfering device is actually used, it is inconvenient for the staff to clamp springs of different sizes. Different types of equipment need to be replaced for springs of different sizes. The versatility is poor, and generally only one end of the spring is ground and chamfered, and the grinding efficiency is poor. Therefore, we propose a spring grinding and chamfering device to solve the existing problems. Utility Model Content
