Extra large water ring vacuum pump body drilling positioning hole tooling

Abstract

The invention discloses a fixture for drilling positioning holes in pump bodies of super-huge type water ring vacuum pumps and belongs to the field of fixtures for manufacturing water ring vacuum pump equipment. The fixture comprises a workbench and is characterized in that a bottom plate (12) is arranged above the workbench through a positioning support assembly; a plurality of groups of bilaterally symmetrical V-shaped supporting seats are arranged above the bottom plate (12); the lower part of each V-shaped supporting seat (1) is provided with a lead screw transmission device capable of driving the V-shaped supporting seat (1) to slide horizontally; a pump body tensioner is arranged on one side of each set of V-shaped supporting seat (1) and lead screw transmission device; the positioning support assembly comprises a plurality of bottom plate supporting seats (8) and bottom plate supporting lean iron blocks (9), which are arranged below the bottom plate (12), and bottom plate adjusting seats (3) symmetrically arranged at four corners of the bottom plate (12). The fixture for drilling the positioning holes in the pump bodies of the super-huge type water ring vacuum pumps can conveniently clamp and fix the pump bodies of the super-huge type water ring vacuum pumps, and the pump body processing and drilling efficiency and accuracy are improved.

Description

technical field [0001] The utility model relates to a tool for drilling positioning holes for a pump body of an extra-large water ring vacuum pump, which belongs to the technical field of water ring vacuum pump equipment manufacturing. Background technique [0002] The water ring vacuum pump is a kind of rough vacuum pump, because the water ring vacuum pump has the characteristics of simple structure and convenient use and maintenance, it has been widely used in all walks of life. At this stage, due to the rapid development of my country's coal mines, chemical industry, pharmaceuticals, papermaking and other industries, the requirements for water ring vacuum pumps are becoming more and more large-scale. Therefore, the demand for large-scale water ring vacuum pumps is increasing. However, due to the large volume and weight of large-scale water ring vacuum pumps, there are also problems in the production and assembly process, such as difficult production and low production eff...

Problems solved by technology

Therefore, the demand for large water ring vacuum pumps is increasing. However, due to the large volume and weight of large water ring vacuum pumps, there are also problems in the production and assembly process, such as difficult production and low production efficiency.

Especially for the pump body structure of the water ring vacuum pump, when the diameter of the pump body exceeds 3 meters and the length exceeds 3.5 meters, the fixing and clamping of the pump body become a difficult problem. , The efficiency of drilling is low, and the positioning holes at both ends of the pump body are not in the same axis, which further causes the quality of the pump body to be unqualified and unable to meet the requirements of use.

In the process of realizing this application, the inventor found that the main reason for the above problems is that in the prior art, there is no tooling specially suitable for the pump body of a large-scale water ring vacuum pump, and it is impossible to drill holes in the pump body.
