Diaphragm gas meter vertical shaft mounting device

Abstract

The invention discloses a diaphragm gas meter vertical shaft mounting device, and aims to solve the problems that a diaphragm gas meter vertical shaft is not mounted in place and the efficiency is low. The device comprises a bottom plate and an oil hydraulic cylinder, wherein a guide shaft is arranged on the bottom plate; one end of the guide shaft is provided with a top plate; the oil hydraulic cylinder is arranged above the top plate; a floating plate is arranged below the top plate; the oil hydraulic cylinder is connected with the floating plate through a joint; the floating plate is connected with two linear guide shafts in a sliding way; the lower surface of the floating plate is provided with an upper jig; the jig is provided with a vertical shaft clamping device; the bottom plate is provided with a low jig which is matched with the upper jig; the lower surface of the floating plate is provided with two first stop blocks; the bottom plate is provided with two second stop blocks; the second stop blocks are positioned on both sides of the lower jig; the central axes of the first stop blocks and the second stop blocks are on the same straight line. By adopting the diaphragm gas meter vertical shaft mounting device, the vertical shaft can be mounted in place every time, vertical shaft deformation caused by excessive compression is avoided, and the assembling success rate is increased.

Description

technical field [0001] The invention relates to an assembly device, in particular to a vertical shaft installation device for a membrane gas meter. Background technique [0002] Diaphragm gas meter is a very commonly used instrument in daily life, and its assembly requirements are relatively high. The working method of the membrane gas meter is that the gas enters the cavity to push the diaphragm in the cavity, and the diaphragm pushes the vertical shaft to rotate in situ to drive its counting device. It can be seen that the vertical shaft is very important. However, at present, there is no very professional equipment for installing the vertical shaft to the lower casing of the membrane gas meter, and most of them are installed manually. The existing hydraulic cylinder-driven vertical shaft press-in machine does not have a limit for the press-in stroke, and the fixation of the vertical shaft It is also unreliable, which easily leads to improper installation of the vertical ...

However, at present, there is no very professional equipment for installing the vertical shaft to the lower casing of the membrane gas meter, and most of them are installed manually. The existing hydraulic cylinder-driven vertical shaft press-in machine does not have a limit for the press-in stroke, and the fixation of the vertical shaft It is also unreliable, which can easily cause the vertical shaft to be installed incorrectly or over-extruded, and the success rate of assembly is also very low
