Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a precise positioning device for processing machine tool accessories. Background Art

[0002] A positioning device is needed in the process of machine tool accessories processing. The main function of the positioning device is to position the accessories during the processing, which can ensure more accurate processing of the accessories. It plays an important role in the processing of accessories. Therefore, people's requirements for positioning devices are getting higher and higher.

[0003] After searching the Chinese patent CN211465571U, a CNC machine tool accessory processing positioning device is disclosed. Through the buffer stabilization mechanism, when the accessory is processed, the movable rod on the buffer stabilization mechanism can be pushed forward, so that the top plate on the movable rod is against the two sides of the accessory to clamp it, and then the distance pushed by the movable rod is tightened by the fastener. When the accessory is being processed, the buffer spring in the top plate can play a buffering role, thereby increasing the stability of the accessory processing and ensuring the quality of the accessory processing.

[0004] During use, the existing positioning device can only simply fix the accessories in place, and does not guide the upper device to the specific and precise position when processing the accessories, resulting in inaccurate positioning. When the specific processing position needs to be positioned, it is often necessary to manually measure and locate the specific position through external auxiliary tools, which makes the positioning efficiency and accuracy of the device low. In addition, during the positioning process, the operator needs to stick close to the fixed accessories, which greatly increases the chance of accidental injury to personnel and reduces the safety of the device.
