Embodiment Construction

[0012] Examples such as figure 1 , figure 2 As shown, a drilling positioning jig for drilling flange mounting holes on the pump body of a multistage pump includes a drilling mold base 1 and a drilling mold base fixing device arranged on a base 2, and is characterized in that the drilling mold The base 1 is in the shape of a ring, and an inner support block 3 is provided in the middle of the jig base 1, and a group of positioning jig holes 4 are arranged in a ring around the jig base 1;

[0013] The fixing device of the drilling base is a connecting plate 5 with clamping blocks 6 at both ends and a through hole 15 in the middle. The clamping blocks 6 are reverse U-shaped, and fixing screw holes are set at the top of each clamping block 6 7. A second fixing screw hole 8 corresponding to the fixing screw hole 7 is provided on the peripheral position of the drilling base 1, and the middle part of the connecting plate 5 is provided with a middle locking hole 12, and the middle lo...

Abstract

The invention discloses a drilling positioning fixture for drilling a flange disc mounting hole in a multi-stage pump body. The drilling positioning fixture comprises a drilling jig base arranged on a pedestal and a drilling jig base fixing device. An inner support block is arranged in the center of the drilling jig base, and a group of positioning drilling jig holes is formed in the peripheral position of the drilling jig base in an annular mode. The drilling jig base fixing device is a connecting plate with clamping blocks at the two ends and a through hole in the middle. A fixing screw hole is formed in the top end of each clamping block. Second fixing screw holes corresponding to the fixing screw holes are formed in the circumferential position of the drilling jig base. A middle locking bolt is arranged in a middle locking hole and the through hole in a penetrating manner, the locking bolt and a positioning groove in the pedestal are fastened, and then a workpiece is locked. Due to the adoption of the drilling jig base fixing device of a double-positioning fastening structure, the locking degree of the drilling jig base, the workpiece and the pedestal is improved, and the drilling positioning fixture has the advantages of being high in clamping degree, precise in position of the drilled mounting hole, and convenient to dismount and mount. The structure of the fixture is simple, and the fixture is easy to obtain.

Description

technical field [0001] The invention relates to a drilling jig, in particular to a drilling positioning jig for drilling a mounting hole of a flange plate on a pump body of a multistage pump. Background technique [0002] At present, when drilling the fixture for the mounting hole of the flange plate of the multi-stage pump body, there is a disadvantage of low clamping degree, which may easily lead to deviation of the position of the flange plate mounting hole drilled, so that the flange cannot be installed, affecting The working performance of the entire product; at the same time, the work efficiency is affected due to the inconvenient disassembly and assembly of the fixture. Contents of the invention [0003] The object of the present invention is to provide a drilling positioning jig for drilling flange mounting holes on the pump body of a multi-stage pump, which solves the problems of low clamping degree and inconvenient disassembly and assembly of the existing drillin...
