Description

Technical Field

[0001] The utility model relates to the technical field of machining centers, in particular to a positioning and clamping device for machining centers. Background Art

[0002] The positioning device is a very common auxiliary production and processing component in the industrial manufacturing industry. It fixes the parts to be processed to facilitate the transportation of the parts or related processing techniques. Especially when performing CNC processing, it is often necessary to fix the parts to be processed through a positioning device. At present, the existing positioning devices generally use cylinders to fix objects to be processed of different sizes. However, the cost of clamping through cylinders is relatively high. At the same time, after the processing of the objects to be processed is completed, debris will be generated, so that the cylinder will drag the debris when driving the splint to recover, which is not convenient for users to collect the debris generated during processing.

[0003] After searching, Chinese patent publication (announcement) No. CN218696120U discloses a clamping and positioning device for a CNC machining center. This patent uses a clamping plate and a knocking ball to drive the clamping plate to clamp the object to be processed when the bidirectional threaded rod rotates. The debris in the machining process can be hit by the knocking ball so that the waste chips enter the collection box through the through opening for collection. However, during the process of the clamping plate clamping the object, if the clamped object is of irregular shape, it is difficult for the clamping plate to correspond to the through opening after clamping it, resulting in the waste chips being difficult to enter the collection box through the through opening. Moreover, when the waste chips enter the collection box and accumulate for a long time, the waste chips may be irregularly accumulated, resulting in a decrease in the utilization efficiency of the internal space of the collection box. Therefore, it is necessary to design a positioning and clamping device for a machining center. Utility Model Content
