Description

Performance test stand for airborne hydraulic valve Technical Field The utility model relates to the technical field of hydraulic valves, in particular to an onboard hydraulic valve performance test bed. Background The hydraulic valve is an automatic element operated by pressure oil, is controlled by the pressure oil of the pressure distribution valve, is usually combined with an electromagnetic pressure distribution valve, and can be used for remotely controlling the on-off of oil, gas and water pipeline systems of a hydropower station. Is commonly used for clamping, controlling, lubricating and other oil ways. There are direct-acting type and pilot type, and multiple pilot type. The existing onboard hydraulic valve performance test bed is stable when performance detection is carried out on the hydraulic valve, however, when the test bed is used after the hydraulic valve and the machine equipment are installed, working vibration is necessarily generated by the machine equipment, and at the moment, the result of detection on the hydraulic valve on the conventional stable performance test bed is not necessarily suitable for the working condition of vibration, so that the hydraulic valve possibly cannot meet the working of the vibration working condition, the actual performance of the hydraulic valve is difficult to determine under the actual vibration working condition, and the situation that the data result is not matched with the actual use condition is caused. Accordingly, in view of the above, an on-board hydraulic valve performance test stand is proposed which is improved against the shortcomings of the conventional structure. Disclosure of utility model The utility model aims to provide an onboard hydraulic valve performance test bed for solving the problems in the background technology. In order to achieve the purpose, the technical scheme is that the machine-mounted hydraulic valve performance test bed comprises a test bed main body, wherein a positioning plate is fixedly arranged on the inner wall of the right side of the test bed main body, a fixed box is fixedly connected to the lower surface of the positioning plate, a transverse frame is fixedly connected to the upper side of the inner surface of the fixed box, a driving motor is fixedly arranged on the rear side of the bottom of the inner surface of the fixed box, a cam is arranged at the front end of the driving motor, a movable rod is rotatably connected to the front side of the surface of a protruding part of the cam, a connecting rod is rotatably connected to the upper end of the movable rod, and an impact plate is fixedly connected to the upper end of the connecting rod in a sliding penetrating mode through the transverse frame. Preferably, an instrument stand is fixedly mounted on the rear side of the upper surface of the test stand main body, and a control member is mounted on the left side of the upper surface of the test stand main body. Preferably, a connecting frame is fixedly arranged on the right side of the lower surface of the test stand main body, and the connecting frame is sleeved outside the fixing box. Preferably, damping spring rods are uniformly and fixedly arranged on four sides of the inner surface of the connecting frame, and the damping spring rods consist of dampers and telescopic springs. Preferably, the tail ends of the damping springs on the same side of the inner surface of the connecting frame are fixedly connected with the same energy absorbing plate, and the surface of the energy absorbing plate is attached to the outer surface of the fixed box. Compared with the prior art, the utility model has the beneficial effects that: 1. According to the utility model, through the arrangement of the transverse frame, the driving motor, the cam, the movable rod, the connecting rod and the impact plate, the driving motor drives the cam to rotate, the cam can pull the lower end of the movable rod to perform arc rotation, at the moment, the movable rod can pull the connecting rod to move, however, the connecting rod can not rotate along with the movable rod under the limit of the transverse frame, only the rotation is converted into up-down linear motion, the connecting rod can reciprocate up and down along with the circular motion of the cam traction movable rod, the impact plate is driven to continuously impact the positioning plate, so that the positioning plate vibrates, and when the cam rotates, due to the irregularity of the form of the cam, the protruding end of the cam can generate centrifugal force, the centrifugal force can also shake the whole fixed box, so that the positioning plate can shake and vibrate, and the collision vibration and the shaking vibration can simulate the vibration condition of the hydraulic valve working in the onboard equipment to the greatest extent, so that the detection indexes of various performances of the hydraulic valve can be simulated more truly after the onboard equipment is install
