Nut inner screw hole batch polishing and deburring device

Abstract

The invention relates to the technical field of fastener polishing and deburring machining, in particular to a nut inner screw hole batch polishing and deburring device which comprises a conveying table. The conveying table comprises two side vertical frames arranged side by side, a chain conveyor is arranged between the two side vertical frames, a plurality of positioning clamps used for positioning and placing nuts are evenly distributed on the chain conveyor, and a burr grinding mechanism used for removing burrs of nut screw holes is assembled between the top ends of the two side vertical frames. A plurality of nuts are positioned, clamped and positioned in a batched mode, an existing randomized inner hole deburring treatment mode is replaced with a simplest and direct rotary grinding removal mode, and on the premise that the treatment efficiency is guaranteed through batched treatment, and the problem that in an existing inner hole deburring treatment process, a non-burr part is abraded, eroded and damaged, and the assembly precision and the assembly strength of a bolt fastener are affected is solved.

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...

AI Technical Summary

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
