Description

Technical Field

[0001] The utility model relates to the technical field of household gas meter production equipment, in particular to an automatic running-in equipment for gas meter movement. Background Technique

[0002] At present, natural gas, as a clean energy source, is widely used; as an important device for measuring household natural gas, the metering performance index of the gas meter is very crucial. In order to improve the stability of the gas meter and the qualification rate during the production process, during the production process of the gas meter movement, air is introduced to simulate the actual operating conditions of the meter, and the gas meter movement is subjected to ventilation running-in. The purpose is to run-in the grinding surfaces of the valve seat and valve cover of the movement to improve the stability of the gas meter movement and the overall machine qualification rate during the production process;

[0003] At present, there are two methods of manual running-in and automatic running-in in the industry. Manual running-in is to manually place the movement on the fixture of the running-in device and operate the running-in table to perform running-in on the movement; automatic running-in is to use a robotic arm to transport the movement into the fixture of the running-in equipment, and the equipment automatically performs running-in on the movement;

[0004] Since manual running-in requires manual placement of the movement on the running-in table, the labor intensity is high. Automatic running-in is the development trend in recent years. Whether it is manual running-in or an automatic running-in device, currently, the method of simulating the actual operation of the gas meter by using a blower to extract air is generally adopted. One blower extracts air from multiple gas meter movements, and the passing flow rate during the running-in of the gas meter is controlled by selecting the air extraction flow rate of the blower. Since one blower is used for multiple gas meter movements and is connected through pipelines, there is pressure loss of air in the pipelines, and the flow rates of the movements at different positions in the same pipeline are inconsistent, resulting in differences in the running-in effect of the movements, and it is not convenient to adjust the flow rate. Therefore, we propose an automatic running-in equipment for gas meter movements. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide an automatic running-in equipment for gas meter movements. By adopting an independent air extraction method, the air extraction flow rate error is reduced, pre-running-in is performed on the movement, and the meters that cannot rotate normally are eliminated to avoid damage to the movement. It can also monitor the running-in ventilation flow rate by detecting the current and voltage. The sealing fixture has the functions of floating up and down and guiding, and can adapt to movements of different specifications, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: an automatic running-in equipment for gas meter movements, including a running-in table frame, a movement conveying line is arranged on the lower side of the front end of the running-in table frame, a running-in device is respectively arranged on the upper side inside the running-in table frame, and a pre-running-in device and a running-in fixture are also included;

[0008] Running-in tooling: It is arranged at the lower end of the running-in device. The running-in tooling is respectively fixedly connected to the left and right sides inside the running-in table frame. By adopting an independent air extraction method, the air extraction flow error is reduced, and the movement is pre-run in. Watches that cannot rotate normally are removed to avoid damage to the movement. It can also monitor the running-in ventilation flow by detecting current and voltage. The sealing tooling has the functions of floating up and down and guiding, and can adapt to movements of different specifications.

[0009] Further, the pre-running-in device further includes a rotation detection sensor. The rotation detection sensor is arranged at the front end of the air extraction fan, and the rotation detection sensor is bidirectionally electrically connected to the external control device. The rotation detection sensor detects whether the movement rotates normally.

[0010] Further, the running-in tooling includes a movement tooling and running-in lifting cylinders. The movement tooling is respectively fixedly connected to the left and right sides inside the running-in table frame. The running-in lifting cylinders are all arranged at the lower end of the running-in device. Installation grooves are respectively arranged on the left and right sides of the upper end of the telescopic end of the running-in lifting cylinders. The movement tooling is respectively located below the vertically adjacent running-in lifting cylinders and can install and position the movement.

[0011] Further, the running-in tooling further includes independent air extraction fans. The running-in lifting cylinders are respectively arranged inside the installation grooves, and the input ends of the independent air extraction fans are all electrically connected to the output end of the external control device, and can perform air extraction running-in on the movement.

[0012] Further, the running-in tooling further includes a sealing tooling. The sealing tooling is respectively arranged on the left and right sides of the lower end of the telescopic end of the running-in lifting cylinders. The upper ends of the sealing tooling are respectively communicated with the vertically adjacent installation grooves. The sealing tooling is designed as a flared mouth, which can ensure the compatibility with the position error of the movement.

[0013] Further, the running-in tooling further includes buffer springs. The buffer springs are respectively arranged between the lower end of the telescopic end of the running-in lifting cylinders and the upper ends of the sealing tooling. The buffer springs are all sleeved outside the lower side of the telescopic end of the running-in lifting cylinders. The buffer springs can not only ensure that the sealing tooling has a pre-pressure on the air outlet pipe, but also be compatible with movements with air outlet pipes of different heights.

[0014] Further, it further includes a movement up and down handling manipulator. The movement up and down handling manipulator is located in front of the movement conveyor line. The input end of the movement up and down handling manipulator is electrically connected to the output end of the external control device and can drive the movement to move.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The automatic running-in equipment for the gas meter movement has the following advantages:

[0016] During operation, pre-running-in evacuates the movement under a small pressure, and the sensor detects whether the meter rotates normally. If it does not rotate, it will be removed, reducing damage to non-rotating movements. Subsequently, independent blowers are used for evacuation, which can avoid pressure loss generated by traditional blower evacuation, ensure that the air extraction volume of each movement is within the required range, and can also monitor the running-in ventilation flow by detecting current and voltage. The sealing tooling has the functions of up-and-down floating and guiding, and can adapt to movements of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS

After positioning, through the regulation of an external solenoid valve, the telescopic end of the running-in lifting cylinder 62 descends, and the sealing tooling 64 seals the movement outlet pipe.
