Gear set meshing detection transmission device for intelligent production of electromechanical valve of gas meter

Abstract

The invention discloses a gear set meshing detection transmission device for intelligent production of an electromechanical valve of a gas meter, and the gear set meshing detection transmission device is provided with an air blowing part which is used for blowing air so as to drive gears in a gearbox gear set to be in meshing transmission through air flow; the air blowing direction of the air blowing piece points to the gear tooth face on the inner side of a tooth groove of a first-stage gear or a last-stage gear in the gearbox gear set. Based on the arranged air blowing part, the air blowing part is used for blowing air, then air flow is used for driving gears in the gear set to transmit, the gear transmission basis needed by detection is achieved, air does not make rigid contact with the gears, the gears can slightly shake or float in the air blowing process, therefore, meshing of gear teeth between adjacent gears can be assisted in the shaking or floating process, it is ensured that all the gears in the gear set can be completely meshed, the gears cannot be extruded and damaged due to the fact that meshing is not in place, the air blowing piece continuously blows air, it can be ensured that the gears can stably transmit, and then the detection result is ensured.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a gear set meshing detection transmission device for intelligent production of gas meter electromechanical valves. Background technique [0002] The gas meter electromechanical valve is used to realize the opening and closing and anti-blocking of the gas meter. The gas meter electromechanical valve is mainly composed of a motor, a gearbox (variable gearbox) and a valve stem actuator. Install the gear shaft and the gear set on the cover of the transmission gearbox, and after the installation is completed, the material is discharged into the next step. [0003] When installing the gear set, the gear set is composed of a plurality of double gears and single gears which are installed sequentially according to the upper and lower stacking structure.

Problems solved by technology

[0003] When installing the gear set, the gear set is composed of a plurality of double gears and single gears which are installed sequentially according to the upper and lower stacking structure. After all the gears are installed, the gear set needs to be meshed. Screen out the gears with casting defects, but because the automatic gear installation cannot ensure whether the gears are installed in place, it is impossible to ensure the gear meshing. As a result, when the gear set is meshed, the gear set that meets the requirements is often not detected due to incomplete meshing. Qualified, resulting in an increase in scrap rate and cost, and because the gears are all small plastic lightweight structures, in order to avoid gears falling off and damage (stuck teeth, broken teeth, etc.), it is impossible to use external drive structures (motors, racks, etc.) to drive The detection of gear transmission cannot avoid the problem of detection error due to the lack of meshing of the gears, which brings many difficulties to the detection of gears
