Clamping device for drilling jig for rocker arm support of diesel engine

Abstract

The utility model relates to a clamping device for a drilling fixture of a rocker arm support of a diesel engine. Including the clamp body, the first combination drill bushing, the second combination drill bushing, the support sleeve, and the limit block; the clamp body is composed of four templates up, down, front and back into a square shape; for holes with low precision, use the first combination drill bushing , including the drill sleeve positioning nut, drill sleeve screw, and anti-rotation pin; the drill sleeve positioning nut is responsible for positioning and fixing the thread for the drill sleeve screw. The drill sleeve screw is not only the drill sleeve, but also the compression screw of the part in the fixture. For precision For higher holes, use the second combined drill sleeve, including fixed drill sleeve, movable drill sleeve, coil seat, and compression nut; the fixed drill sleeve and movable drill sleeve form a drill sleeve set, which is responsible for drilling, expanding and reaming of parts , the coil seat and the compression nut bear the compression effect of the parts in the fixture. The fixture uses the combination of the drill sleeve and the compression device to realize the drilling on the smaller part plane, which not only ensures the drilling of the parts, but also can use the Plane to compress the parts.

Description

technical field [0001] The invention relates to a clamping device for a clamp, in particular to a clamping device for a drill clamp for a rocker arm support of a diesel engine, and belongs to the technical field of mechanical manufacturing technology of diesel engine parts. Background technique [0002] Diesel engine rocker arm supports are generally castings, such as figure 1 , figure 2 As shown in the figure, compared with the general machining parts, the size of this part is small and the shape is complex; the upper and lower, front and rear directions of the part are provided with porous holes, and there are multiple facets with different heights in the same direction, and each facet is provided with There is a hole. Therefore, in order to improve the machining accuracy of the part and improve the machining efficiency, after the part is milled, a drill jig is used to machine the holes on the part. [0003] Due to the small size of the parts, there are many holes to be...
