Abstract

The invention relates to a drilling and clamping device for the back cover of a pump with a valve. A plurality of pads and positioning pins are installed in the middle of the upper end surface of the base plate, and a pressing mechanism is installed at both ends of the bottom plate. The pressing mechanism includes an L-shaped pressing part, and the lower part of the head end of the pressing part is pressed against the upper end surface of the workpiece. , The middle part is hingedly connected with a support rod, the tail end is provided with a threaded hole and a down-pressing stud is installed in the threaded hole, and a cylindrical end face cam is arranged under the down-pressing stud, and the cylindrical end face cam is connected with the bottom plate through a locking screw. A spring is installed on the outer side of the support rod and the inner side of the cylindrical end face cam, one end of the spring is connected with the pressing part, and the other end is fixedly connected with the bottom plate.

Description

technical field [0001] The invention belongs to the field of mechanical parts processing, in particular to a drilling and clamping device for the back cover of a pump with a valve. Background technique [0002] In the field of processing the back cover of the pump with valve, it usually involves drilling the back cover of the pump with valve. The back cover of the pump with valve is first formed in one piece by casting process, which cannot be directly applied. It needs to be further processed by the finishing center machine tool. Due to the complex and irregular shape of the back cover of the pump with valve, it is difficult to fix it on the finishing machine tool, which brings difficulties to the drilling of the back cover of the pump with valve. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides a drilling and clamping device for the rear cover of the valved pump with simple structure, conv...
