Automatic water meter cover machine

Abstract

The invention relates to an automatic water meter capping machine. The automatic water meter capping machine comprises a frame, wherein an ear ring connection type hydraulic cylinder is arranged on the top of the frame; a hydraulic cylinder support plate and two guide post support plates are connected to the frame; the two ends of the hydraulic cylinder are hinged to the hydraulic support plate and an upper lifting support plate through an upper bolt and a lower bolt respectively; the two ends of four guide posts are connected with upper and lower guide post support plates respectively; a hydraulic motor revolving shaft is connected with a water meter cover chuck; a hydraulic motor shell is connected to a lower lifting support plate; the upper and lower lifting support plates are connected through two support posts; eight guide sleeves are connected to the upper and lower lifting support plates; four guide posts and eight guide sleeves construct a sliding pair; a water meter supporting seat is connected to the lower guide post support plate; two limiting switches are arranged on limiting switch support plates respectively; the two limiting switch support plates are connected to the frame. The automatic water meter capping machine is compact in structure, and runs stably and reliably. A water meter cap can be tightened by set constant torque, and the situation of unstable accuracy of a water meter due to difference in the tightening torque of the water meter cap can be avoided.

Description

technical field [0001] The invention relates to an automatic water meter capping machine, which can automatically tighten the water meter cover according to the set torque, and can adjust the tightening torque according to the requirements, and can also change chucks and water meter support seats of different sizes. Thereby, the work of tightening the water meters of different sizes and specifications is realized. Background technique [0002] In the water meter production process of the water meter factory, the assembly of water meter parts is a very important link, especially the process of screwing the water meter cover and the water meter case together is particularly important, because in the case of the same accuracy of the water meter parts , Different tightening torques will profoundly affect the accuracy of the water meter. If the tightening torque is too large, the force on the water meter core will be too large, the error of the water meter will be large when the...

Problems solved by technology

If the tightening torque is too large, the force on the water meter core is too large, the error of the water meter is large when the water meter is working, the tightening torque is too small, and the water meter will leak, etc., which will also affect the accuracy of the water meter

In the past, in the process of water meter assembly and production in the factory, workers used more methods to tighten the water meter cover by using a specific structure of the water meter cover tightening wrench, relying on the workers' own experience and feeling to tighten the water meter cover, due to individual differences between people , and the existence of individual differences under different physical and mental conditions at different times, resulting in differences in the tightening torque of each water meter cover, which will affect the accuracy of the overall batch of water meters

At the same time, workers tighten the water meter cover through physical strength, which is labor-intensive and inefficient
