Clamp special for machining valve block of pneumatic roof bolter

Abstract

The invention discloses a clamp special for machining a valve block of a pneumatic roof bolter. The hole pitch precision of the valve block of the roof bolter can be effectively improved, the technological error is reduced, using is convenient, and the structure is simple. A disc is arranged on one side of a fixed support of the clamp, and the disc is connected with the fixed support through a central spindle assembly; the central spindle assembly comprises a bearing arranged at one end of the disc and is used for supporting the disc and all fixing pieces on the disc to rotate around the axis;the clamp further comprises an upper drill mold plate, a lower drill mold plate, a left vertical plate and a right vertical plate, a positioning pin and a positioning inserting pin; the upper drill mold plate, the lower drill mold plate, the left vertical plate and the right vertical plate are fixed to the disc through bolts; a plurality of hole positions are formed in each of the upper drill mold plate and the lower drill mold plate; the upper drill mold plate, the lower drill mold plate, the left vertical plate and the right vertical plate form a square box whole; the positioning pin is connected with the upper drill mold plate and used for positioning the workpiece precision; and pin holes matched with the positioning inserting pin are formed in the fixed support and the disc and usedfor limiting the relative motion of the fixed support and the disc.

Description

technical field [0001] The invention relates to a processing device for a pneumatic rock bolt drilling machine, in particular to a fixture specially used for processing a valve block of a pneumatic rock bolt drilling machine. Background technique [0002] The valve block is an important part of the pneumatic rock bolt rig. At present, the drilling of product parts generally adopts manual positioning technology. For complex parts, this process mode has low working accuracy, large errors, low efficiency, and the position of the hole distance cannot be guaranteed. Product quality unstable. The drilling tooling of the valve block of the pneumatic rock bolt rig of the present invention has high drilling precision, small error, stable relative position, reliable product quality, is conducive to improving labor productivity and reducing production costs, is beneficial to improving workers' working conditions, and ensures safe production. Contents of the invention [0003] The te...
