Multi-parameter pneumatic comprehensive measurement device for water pump shell

Abstract

The invention discloses a multi-parameter pneumatic comprehensive measurement device for a water pump shell. The multi-parameter pneumatic comprehensive measurement device comprises a working table surface (3), a speed reducing motor (14), a rotating plate (5) and the like. The multi-parameter pneumatic comprehensive measurement device is characterized in that an upper measuring head body (8) is connected with a top board (11) and an air cylinder (23) through a lifting board (9) and the like; at least two internal diameter coaxiality spray holes are respectively arranged on the upper measuring head body (8); the internal diameter coaxiality spray holes are arranged at the same axis position and the upper measuring head body (8) is respectively provided with at least two pairs of internal diameter pneumatic spray holes; a pair of internal diameter pneumatic spray holes (4-1), an external diameter coaxiality spray hole (4-2) and a verticality spray hole (4-3) are respectively arranged on a lower measuring head body (4); and the external diameter coaxiality spray hole (4-2) and the internal diameter coaxiality spray holes are located at the same axis position. The multi-parameter pneumatic comprehensive measurement device disclosed by the invention has the advantages of being simple in structure, high in efficiency, accurate in measurement, high in precision and long in service life. The online automatic measurement can be realized.

Description

Technical field: [0001] The invention relates to a multi-parameter pneumatic comprehensive measuring device for a water pump casing, which belongs to the technical field of measuring instruments and is used for measuring 3 inner diameters, 1 outer diameter, 3 roundness, 3 coaxiality, 1 Verticality. Background technique: [0002] At present, the inner diameter and outer diameter of the water pump housing are mainly measured by inner micrometer, which is inaccurate, low precision, large error caused by human operation, high cost and short service life. There is no good solution for the detection of shape and position errors such as roundness, coaxiality, and perpendicularity. Only three-coordinate sampling inspection is possible, which is extremely inefficient and it is impossible to realize process inspection and online automatic inspection. Invention content: [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned prior art and...
