A slotting method for the inner wall of a discontinuous box

Abstract

The invention discloses a method for slotting and cutting the inner wall of a noncontinuous box. The method includes: step 1, making two process supports, and machining a reference face; step 2, machining six connecting holes; step 3, machining a right inner wall face; step 4, machining a left inner wall face. By the method, machining of the noncontinuous box on a slotting machine is realized, and shape and position accuracy of each machined face is guaranteed effectively; the problem of machining rebound deformation caused by rigidity difference of the noncontinuous box is solved; the problem of deformation of a toolbar due to the fact that the toolbar extends out excessively is solved; the problems of positioning and centering when the noncontinuous box is machined on the slotting machine are solved; requirements on position degree between holes in the box and the left inner wall face as well as the right inner wall face of the box are met, the method is high in universality, and production efficiency is improved effectively.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a slotting method for the inner wall of a discontinuous box. Background technique [0002] The iron driller is a hydraulic drive, so that the slider drives the jaws to slide inside the box to realize the clamping device for the jaws to the drill pipe. Among them, the box body requires processing of its internal sliding surface. Since this type of box body belongs to a discontinuous U-shaped opening structure, its sliding surface is also discontinuous. The body produces elastic deformation; the inner wall structure of the whole box is discontinuous and deep, the overhang of the tool bar is too long, the rigidity is reduced, and the tool bar is deformed; it is difficult to align the box body, and it is difficult to ensure the position of the connecting pin hole Mass production caused a lot of trouble and affected product quality.
