Description

Technical Field

[0001] The utility model relates to the field of positioning tooling, in particular to a positioning tooling for an electro-hydraulic steering control valve. Background Art

[0002] The electro-hydraulic steering gear control valve is a hydraulic component, which is mainly used in more than 20 industries such as petroleum, chemical industry, electric power, and various hydraulic transmission systems and devices to change the direction of the oil circuit, thereby controlling the movement direction of the actuator. It can realize unidirectional, bidirectional control and control of complex movements. In order to ensure the accurate and stable position of the electro-hydraulic steering gear control valve, so as to ensure that it can correctly control the flow direction of the liquid when needed, it is necessary to use a positioning tool for positioning connection. The existing electro-hydraulic steering gear control valve is installed using its own mounting structure during installation and transportation. When the valve is opened and closed many times, oil impurities will remain at the valve port, which will cause blockage in the long run. At the same time, due to the influence of external vibration, its own mounting structure will be displaced, causing the valve to deviate horizontally, affecting the oil circuit transportation effect and reducing positioning protection; Therefore, we proposed a positioning tool for the electro-hydraulic steering gear control valve to solve the above problems. Utility Model Content

[0003] In order to overcome the problem of the electro-hydraulic steering control valve, when the valve is opened and closed many times, oil impurities will remain in the valve port, which will cause blockage over a long period of time. At the same time, due to external vibration, the installation structure itself will be displaced, causing the valve to deviate horizontally.

[0004] The technical solution of the utility model is: a positioning tool for an electro-hydraulic steering gear control valve, comprising a positioning component, a control valve body, a connecting balance plate, a docking shock-absorbing component and a dredging and cleaning component; positioning components for clamping and positioning are provided on both sides of the control valve body, a connecting balance plate for supporting the overall stability is provided at the lower end of the positioning component, a dredging and cleaning component for cleaning the control valve body is provided at the lower middle part of the positioning component, and a docking shock-absorbing component for shock-absorbing protection of the control valve body is provided on the end of the connecting balance plate away from the positioning component.

[0005] Preferably, observation is made through the bubble ball. When the bubbles inside the bubble ball shift to the orientation column on one side, it can be seen that the overall control valve body is deflected. The driving motor drives the rotating shaft to drive the clamping sleeve to clamp and swing, so that the bubbles inside the bubble ball are located in the center and are in a stable state. The overall positioning and flatness performance is maintained, and the water pipe is connected to the filling pipe. The synchronous camera observes the oil port of the control valve body to increase the cleaning positioning. The driver is adjusted through the rotating rod and the connecting block to reach a suitable position, and its injection pipe sprays water for rapid cleaning operations.

[0006] Preferably, the positioning assembly includes a clamping sleeve, a rotating shaft, a spring column, a spring damper, a driving motor, a balancing disk, a bubble ball, an orientation column and a positioning frame. There are two groups of positioning frames, and a rotating shaft is passed through the two groups of positioning frames. A driving motor is provided at one end of the rotating shaft, and a clamping sleeve matching the docking shock-absorbing assembly is provided in the middle of the rotating shaft. The driving motor drives the rotating shaft to drive the clamping sleeve to clamp and swing, so that the bubbles inside the bubble ball are located in the center and are in a stable state.

[0007] Preferably, a limiting groove is provided on the outer side of the clamping sleeve, an adsorption plate is fitted on the inner side of the clamping sleeve, mounting holes are penetrated at both ends of the clamping sleeve, a spring column is provided in the middle of the limiting groove, a spring damper is provided inside the spring column, and the adjusting bolt drives the shock-absorbing ball on the guide plate through the rotating sleeve adjustment extension plate to fit with the end of the spring column.

[0008] Preferably, a balancing disk is provided at the upper end of the positioning frame, a bubble ball is provided at the upper end of the balancing disk, and an orientation column is provided in a ring shape on the outer side of the bubble ball. When observing through the bubble ball, when the bubbles inside the bubble ball shift to the orientation column on one side, it can be seen that the overall control valve body is deviated.

[0009] Preferably, installation grooves are evenly distributed on the surface of the connected balance plate, and the docking shock-absorbing assembly includes a rotating sleeve, an adjusting bolt, an extension plate, a guide plate, a shock-absorbing ball and a bonding layer. The adjusting bolt adjusts the extension plate through the rotating sleeve, and the extension plate is located in the middle of the rotating sleeve. A guide plate is provided at the end of the extension plate away from the rotating sleeve, and a shock-absorbing ball is provided in the middle of the guide plate. The outer wall of the shock-absorbing ball is covered with a bonding layer. The adjusting bolt adjusts the extension plate through the rotating sleeve to drive the shock-absorbing ball on the guide plate to fit with the end of the spring column, thereby increasing local supporting force and improving the overall supporting effect.

[0010] Preferably, the dredging and cleaning assembly includes a connecting block, a rotating rod, a driver, a support plate, a water tank, a spray pipe, a filling pipe and a camera. The driver is movably connected to the connecting block through the rotating rod. The outer side of the rotating rod is sleeved with a support plate, and spray pipes are evenly distributed on one side of the support plate. A water sprinkler is provided inside the spray pipe. Water flows into the water tank through the filling pipe, is pressurized by a water pump, and is sprayed out by the water sprinkler to fall on the oil port for cleaning.

[0011] Preferably, a water tank is provided at the lower end of the injection pipe, a water pump is provided inside the water tank, a filling pipe is provided in the middle of the water tank, and a camera is provided at the outer end of the support plate. The water pipe is connected to the filling pipe, and the oil port of the control valve body is observed synchronously with the camera to increase the cleaning positioning.

[0012] Beneficial effects of the utility model:

[0013] 1. Different from the previous installation structure using its own installation structure, an additional positioning component is set up, and the clamping operation is performed by two sets of clamping sleeves. Through the bubble ball, it is observed that when the bubble inside the bubble ball deviates to the azimuth column on one side, it can be seen that the overall control valve body is deflected. The driving motor drives the rotating shaft to drive the clamping sleeve to clamp and swing, so that the bubble inside the bubble ball is located in the center and is in a stable state, maintaining the overall positioning and flatness performance, and greatly improving the control performance.

[0014] 2. In order to increase the fixed adjustment, the installation operation can be carried out separately through the installation hole and the limit groove to keep the connected pipe in position. Since the installation groove is positioned to connect the balance plate, the bottom installation positioning performance is increased and the shaking is reduced. Synchronously with the swing deviation of the clamping sleeve, the adjusting bolt drives the shock-absorbing ball on the guide plate through the rotating sleeve adjustment extension plate to fit with the end of the spring column, thereby increasing the local supporting force and improving the overall supporting effect.

[0015] 3. When cleaning is required, connect the water pipe to the filling pipe, and use a synchronous camera to observe the oil port of the control valve body to increase the cleaning positioning. The driver adjusts the rotating rod and the connecting block to reach a suitable position. The jet pipe sprays water for rapid cleaning operations, which increases cleaning protection and facilitates secondary positioning pipeline connection. BRIEF DESCRIPTION OF THE DRAWINGS
