A combined platform for hydraulic valve assembly and sealing test bench

Abstract

The invention relates to a combined platform for a hydraulic valve general assembly seal test bed. The combined platform comprises an unfolding beam, a lateral movement motor, a lead screw, a lateral movement base platform, a front hanging cylinder, an L-shaped hanging frame, a transposition motor, a pusher dog disk, a pressing cylinder, a pressure disk, a cross beam, swing arms, pressure hammers and lateral unfolding cylinders, wherein the lateral movement motor is fixed to the rear end of the unfolding beam, the rear end of the lead screw is connected with the lateral movement motor, the front hanging cylinder is installed on the front portion of the lateral movement base platform, the pressing cylinder is installed at the rear of the lateral movement base platform, the cross beam is installed at the lower end of the front hanging cylinder, the L-shaped hanging frame is installed at the lower end of the middle of the cross beam, the swing arms are correspondingly hinged to the cross beam, the pressure hammers are correspondingly fixed to the lower ends of the swing arms respectively, one end of each lateral unfolding cylinder is hinged to the L-shaped hanging frame, the other end of each lateral unfolding cylinder is hinged to the corresponding swing arm, the transposition motor is installed on the rear side face of the front portion of the L-shaped hanging frame, and the pusher dog disk is installed on the transposition motor. The combined platform for the hydraulic valve general assembly seal test bed has the advantages of being reasonable in structural design, high in automation degree, convenient to operate and control and the like, and the functions of blocking, station rotating and valve opening and closing can be automatically achieved in a sealing performance test.

Description

technical field [0001] The invention relates to the technical field of valve detection, in particular to a combined platform for a hydraulic valve assembly sealing test bench. Background technique [0002] The equipment structure of the existing valve sealing test bench is relatively simple, and the manual operation method is adopted. Since the valve needs to be moved back and forth during the testing process, the physical exertion of the workers is relatively large, and the labor intensity is high. The upper and lower passages are tested separately for sealing. Existing factories adopt the method of manually moving and changing positions, but the valve itself is heavy, and it is troublesome to carry and change positions. At present, when testing the tightness of valves, manual rotation of the turntable , in order to realize the opening or closing of the valve, if the sealing of the valve is not up to standard, it will produce water jet, which will easily wet the clothes of ...

The upper and lower passages are tested separately for sealing. Existing factories adopt the method of manually moving and changing positions, and the valve itself is heavy, so it is troublesome to carry and change positions. At present, when testing the tightness of valves, manual rotation of the turntable is used. , in order to realize the opening or closing of the valve, if the sealing of the valve is not up to standard, it will produce water jet, which will easily wet the workers' clothes and bring inconvenience to the sealing test
