Problems solved by technology

[0003] The burr in the inner screw hole of the nut is the inner hole burr. The removal of the inner hole burr has always been a difficult problem in workpiece processing. The removal of the inner hole burr in the prior art mainly includes fluid polishing removal method, electrolytic polishing removal method, and magnetic polishing removal method. method, vibration polishing removal method, thermal energy polishing removal method, etc.; although the above methods can effectively remove burrs to a large extent, and the deburring efficiency is greatly enhanced, they are all random deburring methods, so there are obvious disadvantages , For example: the fluid polishing removal method will grind the non-burr part while deburring, so it will affect the fit accuracy of the nut, and the electrolytic polishing removal method will cause erosion to the non-burr part while deburring, so it will also affect the nut Fitting accuracy

Abstract

The invention relates to the technical field of fastener grinding and deburring processing, in particular to a batch grinding and deburring device for inner screw holes in nuts, which includes a conveying platform, and the conveying platform includes two side stands arranged side by side; A chain conveyor is arranged between the side stands, and a number of positioning fixtures for positioning and placing of nuts are evenly distributed on the chain conveyor, and a set of clamps for removing nuts and bolts is installed between the tops of the two side stands. The burr grinding mechanism for hole burrs; through batch positioning and clamping positioning of multiple nuts, the most simple and direct removal method of rotary grinding is used to replace the existing randomized inner hole deburring treatment method. Under the premise of processing efficiency, it solves the problem that the existing inner hole deburring process causes wear, erosion and damage to non-burr parts and affects the assembly accuracy and assembly strength of bolt fasteners.

Description

technical field [0001] The invention relates to the technical field of grinding and deburring processing of fasteners, and specifically proposes a batch grinding and deburring device for inner screw holes of nuts. Background technique [0002] Bolt fasteners, referred to as bolts, bolts are the most common and widely used type of fasteners in the field of mechanical fixing and installation. In the process of processing, burrs will inevitably appear in the inner screw hole of the nut. In order not to affect the cooperation effect between the nut and the screw, it is generally necessary to remove the burrs. [0003] The burr in the inner screw hole of the nut is the inner hole burr. The removal of the inner hole burr has always been a difficult problem in workpiece processing. The removal of the inner hole burr in the prior art mainly includes fluid polishing removal method, electrolytic polishing removal method, and magnetic polishing removal method. method, vibration polish...
