Problems solved by technology

[0002] Vacuum pump refers to the device or equipment that uses mechanical, physical, chemical or physicochemical methods to pump air from the pumped container to obtain vacuum. Most vacuum pumps are assembled and mass-produced through vacuum pump assembly lines. The requirements are very strict, so an air tightness detector needs to be installed on the vacuum pump assembly line to monitor the air tightness of the vacuum pump sealing valve after production and assembly. There are many kinds of air tightness detectors in the prior art, among which the rotary air tightness The tightness testing machine rotates the monitoring shaft with the air pressure sensor on the top and sends it into the sealing valve, and monitors the air pressure difference between the inside and outside through the sensor, and outputs the data to the screen of the processor, so that the air pressure of the vacuum pump being tested can be visually observed. However, in the process of sending the rotating monitoring shaft into the sealing valve, it is likely that the inner wall of the sealing valve will be scratched due to a slight deviation of the insertion angle, and the difference in air pressure inside and outside during the vacuuming process will cause the monitoring The slight movement of the shaft is more likely to cause scratches. Although the scratches are very shallow, they will still affect the airtightness and reduce the airtightness of the vacuum pump.

Abstract

The invention discloses an air tightness detection machine for a vacuum pump assembly line, which structurally comprises a base, an operation table, a control table, a fixed seat and a tester, the top surface of the base is in welded connection with the bottom surface of the operation table, the bottom surface of the control table is fixedly mounted on the top surface of the operation table, and the bottom surface of the fixed seat is welded on the top surface of the operation table; the bottom surface of the tester is fixedly mounted on the top surface of the operation table, a testing machine comprises a rotating machine, a welding table, a testing head, a data rod and an air pressure head, and the top surface of the welding table is connected with the bottom surface of the rotating machine in a welded mode. The air pressure inside and outside a working vacuum pump is monitored through the air pressure head and the test head so as to obtain air tightness data of the vacuum pump; When the testing head is screwed into and out of the sealing valve of the vacuum pump through the rotating machine, the inner wall of the sealing valve can be polished through a grinding shaft fixed on the rotating shaft, so that scratches generated on the inner wall of the sealing valve in the testing process are flattened, and the adverse effect on the air tightness of the vacuum pump due to the existence of the scratches is avoided.
