Clamping device for diesel engine rocker arm support drill clamp

Abstract

The utility model discloses a clamping device for a diesel engine rocker arm support drill clamp. The clamping device comprises a clamp body, a first combined drill bushing, a second combined drill bushing, a supporting sleeve and a limiting block, wherein the clamp body is formed by combining an upper template, a lower template, a front template and a back template into a square shape; for holes with low precision, the first combined drill bushing is used and comprises a drill bushing positioning nut, a drill bushing screw and an anti-rotating pin; the drill bushing positioning nut is used for positioning and fixing threads for the drill bushing screw, and the drill bushing screw is not only a drill bushing and but also a compression screw of a part in the clamp; for holes with high precision, the second combined drill bushing is used and comprises a fixed drill bushing, a movable drill bushing, a solenoid seat and a compression nut; the fixed drill bushing and the movable drill bushing form a drill bushing group which is used for drilling, expanding and hinging the part; and the solenoid seat and the compression nut are used for compressing the part in the clamp. The clamp is combined with a compression device by the aid of the drill bushings, so that the part is guaranteed to be drilled on a smaller part plane, and meanwhile the part can be compressed by the aid of the plane.

Description

technical field [0001] The invention relates to a clamping device of a clamp, in particular to a clamping device of a diesel engine rocker arm support drill clamping device, which 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, compared with general machined parts, this part is small in size and complex in shape; holes are provided in the up, down, front and back directions of the part, and multiple facets with different heights are set in the same direction, and each facet is set There is one hole. Therefore, in order to improve the machining accuracy of the part and improve the machining efficiency, after the part is milled, a drilling jig is used to process the holes on the part. [0003] Due to the small parts, there are many holes to be processed with high precision, such as: rocker shaft support h...
