Problems solved by technology

[0002] In the past, when drilling the cylinder cover of a diesel engine, the workpiece was usually fixed on the platform of the radial drilling machine through the pressure plate. The disadvantages are that the positioning and clamping of the workpiece are unreliable, the machining accuracy is low, and the clamping of the workpiece by the pressure plate is labor-intensive for workers. Large size and low production efficiency; in addition, for different types of cylinder covers, corresponding pressure plates need to be configured, and the production cost is high

Abstract

The invention provides a drilling fixture for a cylinder cover, which can effectively improve positioning precision and clamping precision of a workpiece, accordingly guarantees machining precision of the workpiece, can greatly reduce labor intensity of workers, enhances production efficiency and lowers production cost. The drilling fixture comprises a bottom plate, and a fixing plate is vertically mounted on the bottom plate. The drilling fixture is characterized by further comprising a workpiece positioning and clamping device and a plate jig, the workpiece positioning and clamping device is fixed onto a workpiece clamping surface of the fixing plate, the plate jig is connected with the upper end of the fixing plate by a hinge device, and a drill bushing is correspondingly mounted on the plate jig according to a to-be-drilled position of the workpiece.

Description

technical field [0001] The present invention relates to the field of machining tooling for diesel engine parts, specifically the drilling jig for cylinder covers. Background technique [0002] In the past, when drilling the cylinder cover of a diesel engine, the workpiece was usually fixed on the platform of the radial drilling machine through the pressure plate. The disadvantages are that the positioning and clamping of the workpiece are unreliable, the machining accuracy is low, and the clamping of the workpiece by the pressure plate is labor-intensive for workers. Large size and low production efficiency; in addition, for different types of cylinder covers, corresponding pressure plates need to be configured, and the production cost is high. Contents of the invention [0003] In view of the above problems, the present invention provides a drilling jig for the cylinder cover, which can effectively improve the positioning and clamping accuracy of the workpiece, thereby en...
