Description

Technical Field

[0001] The utility model belongs to the technical field of tooling fixtures, and in particular relates to an auxiliary positioning component for installing a hydraulic valve. Background Art

[0002] A hydraulic valve is an assembly with a predetermined control function formed by integrating or combining multiple selected hydraulic control valves on the same metal block. The use of a hydraulic valve can not only simplify the design and installation of a hydraulic system, but also facilitate the integration and standardization of a hydraulic system, thereby improving accuracy and reliability. The hydraulic valve needs to be fixed during the processing, cleaning and installation of the hydraulic valve. In the prior art, a new type of tooling fixture for processing a hydraulic valve body is disclosed, and the document number is: CN213003971U. The technical solution is to use an adjusting device to cooperate with an adjusting bolt, and use an X-direction positioning block to fix the hydraulic valve body in the X direction, and then use a push plate to cooperate with a Y-direction positioning block to fix the hydraulic valve body in the Y direction, thereby fixing and clamping the hydraulic valve body. By replacing the connecting piece and the sub-plate, different types of hydraulic valve bodies can be clamped.

[0003] The above scheme can achieve fixed clamping of the hydraulic valve body and can be used when the hydraulic valve body does not need to be moved and remains in the same position for a long time. Most of them can be used for processing and cleaning of the hydraulic valve body. However, during the installation process, the hydraulic valve body often needs to be moved to a certain height position. Only fixed clamping of the hydraulic valve body is not enough to meet the use requirements. Then, the movement of the hydraulic valve body requires manual transportation or the use of other tooling fixtures. If it is carried manually, the hydraulic valve body is prone to fall, causing damage to the hydraulic valve body and even personal injury to personnel. If other tooling fixtures are used, the hydraulic valve body needs to be disassembled and then installed, which wastes time and reduces the installation efficiency of the hydraulic valve body.

Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but only represents the selected embodiments of the present application.

[0024] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be an electrical connection; it can be a hydraulic oil circuit connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] See also Figures 1 to 3As shown, an auxiliary positioning component for installing a hydraulic valve includes a horizontally placed mounting plate 1, with handles 2 installed on both sides of the mounting plate 1 for easy carrying. A movable pushing frame 3 is connected to the mounting plate 1, and a mobile positioning fixture is connected to the pushing frame 3. The mobile positioning fixture can fix and transport the hydraulic valve to be installed. A matching groove 4 corresponding to the mobile positioning fixture is also provided on the mounting plate 1. When the mobile positioning fixture is located in the matching groove 4, the hydraulic valve can be conveniently carried to the mobile positioning fixture, and then the mobile positioning fixture can transport the hydraulic valve to a specified height position for easy installation.

[0026] The above-mentioned pushing frame 3 includes a vertical beam 5 and a horizontal beam 6. The lower end of the vertical beam 5 is connected to the mounting plate 1, and the upper end of the vertical beam 5 is connected to the horizontal beam 6. The horizontal beam 6 and the vertical beam 5 are connected to form a "T"-shaped pushing frame 3. A horizontal slide groove 7 is opened on the upper surface of the mounting plate 1. The lower end of the vertical beam 5 is slidably connected in the horizontal slide groove 7, so that the pushing frame 3 can slide along the length direction of the horizontal slide groove 7.

[0027] See also Figures 4 to 6 As shown, the above-mentioned mobile positioning fixture includes a flat lifting arm 8 and a hydraulic valve clamping mechanism 9, wherein the flat lifting arm 8 is fixed on the vertical beam 5 of the pushing frame 3, and the flat lifting arm 8 is arranged in parallel with the horizontal beam 6 of the pushing frame 3, and the hydraulic valve clamping mechanism 9 is slidably connected to the flat lifting arm 8. Specifically: a strip groove 10 is arranged on the lower surface of the flat lifting arm 8, and the strip groove 10 is also parallel to the horizontal beam 6. A slide seat 11 is connected in the strip groove 10, and the hydraulic valve clamping mechanism 9 is fixedly connected to the slide seat 11. When the slide seat 11 slides along the length direction of the strip groove 10, it will drive the hydraulic valve clamping mechanism 9 to move accordingly. At this time, a screw is arranged on the slide seat 11. The displacement screw 12 is threadedly screwed into the threaded hole. The displacement screw 12 is parallel to the horizontal boom 8 and is located below the horizontal boom 8. One end of the displacement screw 12 passes through the slide 11 and the vertical beam 5 at the same time, and is connected to the output shaft of the drive motor 13. The drive motor 13 is fixed on the cross beam 6. When the drive motor 13 is running, its output shaft will drive the displacement screw 12 to rotate, so that the slide 11 moves in the strip groove 10, and then adjust the position of the slide 11 relative to the displacement screw 12; an anti-slip disk 14 is fixed at the other end of the displacement screw 12 to prevent the slide 11 from separating from the displacement screw 12 when the relative displacement screw 12 moves.

[0028] The hydraulic valve clamping mechanism 9 includes a power hydraulic rod 15 connected to the slide 11. The power hydraulic rod 15 can be retracted vertically. A bottom support plate 16 is fixedly connected to the lower end of the power hydraulic rod 15. The bottom support plate 16 corresponds to the matching groove 4 on the mounting plate 1. When the power hydraulic rod 15 extends toward the mounting plate 1, it drives the bottom support plate 16 to move vertically into the matching groove 4. At this time, the upper surface of the bottom support plate 16 is flush with the upper surface of the mounting plate 1. In this way, the hydraulic valve can be conveniently placed on the bottom support plate 16, and then the power hydraulic rod 15 can be controlled. When it contracts in the direction away from the mounting plate 1, it will drive the bottom support plate 16 to lift the hydraulic valve to a certain height; at this time, a slide cylinder 17 is sleeved on the power hydraulic rod 15, the inner diameter of the slide cylinder 17 is larger than the diameter of the power hydraulic rod 15, and an upper clamping plate 18 is fixedly connected to the outer surface of the slide cylinder 17, and the upper clamping plate 18 is fixed to the lower surface of the slide seat 11 through a connecting rod 19. The upper clamping plate 18 and the bottom support plate 16 correspond to each other and the central axes are on the same straight line. The upper clamping plate 18 can cooperate with the bottom support plate 16 to form a stable clamping of the hydraulic valve between the two;

[0029] When the hydraulic valve needs to be installed to the specified position, first control the power hydraulic rod 15 to extend in the direction close to the mounting plate 1, and drive the bottom support plate 16 to approach the mounting plate 1, until the bottom support plate 16 enters the matching groove 4 on the mounting plate 1. After the hydraulic valve is placed on the bottom support plate 16, control the power hydraulic rod 15 to shrink in the direction close to the upper clamping plate 18, and drive the bottom support plate 16 with the hydraulic valve placed away from the mounting plate 1 and move towards the upper clamping plate 18 until the hydraulic valve placed on the bottom support plate 16 contacts the upper clamping plate 18. At this time, the hydraulic valve between the upper clamping plate 18 and the bottom support plate 16 forms a stable clamp, which avoids the hydraulic valve from shaking or being unstable during movement.

[0030] See also Figure 7 As shown, the bottom support plate 16 includes a positioning plate 20 and an outward moving plate 21, wherein the positioning plate 20 is fixedly connected to the lower end of the power hydraulic rod 15, and the outward moving plate 21 is movably connected to the upper part of the positioning plate 20, and a limiting groove 22 is provided on the upper surface of the positioning plate 20, where the side of the positioning plate 20 away from the power hydraulic rod 15 is set as an inclined surface, the limiting groove 22 extends along the length direction of the positioning plate 20 and is connected to the inclined surface, the other end of the limiting groove 22 is in a closed state, and a smooth groove 23 is provided on the inner side wall of the limiting groove 22 The two ends of the smooth groove 23 are closed and connected with the limiting groove 22. A slider 24 is arranged on the lower surface of the outer moving plate 21. The slider 24 can fit in the limiting groove 22 and slide along the length direction of the limiting groove 22. A shaft rod 25 also passes through the slider 24. Both ends of the shaft rod 25 extend out of the slider 24 and fit to slide in the smooth groove 23. A return spring 26 is connected between the slider 24 and the limiting groove 22. The return spring 26 is arranged on a side close to the power hydraulic rod 15. The return spring 26 can generate a restoring force when stretched;

[0031] In the initial state, the return spring 26 is in a relaxed state. At this time, the slider 24 is located on the side of the limiting groove 22 close to the power hydraulic rod 15. When a horizontal force away from the power hydraulic rod 15 is applied to the slider 24, the slider 24 will drive the outer moving plate 21 to move along the limiting groove 22 in the direction away from the power hydraulic rod 15. At the same time, the shaft rod 25 slides in the same direction along the smooth groove 23. When the shaft rod 25 slides to the end of the smooth groove 23, the outer moving plate 21 changes from a horizontal state to an inclined state, and the lower surface of the outer moving plate 21 contacts the inclined surface of the positioning plate 20. In this process, the return spring 26 is stretched to generate a restoring force. When the outer moving plate 21 is in a tilted state, the hydraulic valve will naturally fall to the specified height position.

[0032] A traction component is also provided on the positioning plate 20, and the traction component can apply a pulling force to the slider 24 away from the power hydraulic rod 15. The traction component includes a winding roller 27 and a guide wheel 28. A shaft frame 29 is fixed to the lower surface of the positioning plate 20, and the shaft frame 29 is arranged on a side close to the power hydraulic rod 15. The winding roller 27 is movably sleeved on the shaft frame 29. A traction rope 30 is wound on the winding roller 27, and a rotating grip 31 is provided on the side of the winding roller 27. By rotating the rotating grip 31, the traction rope 30 can be wound or released; at the same time, a guide groove 32 is provided on the lower surface of the positioning plate 20, and the guide wheel 28 is axially connected in the guide groove 32. The guide wheel 28 is located on the side of the positioning plate 20 away from the power hydraulic rod 15. At this time, a rope hole 33 is provided in the positioning plate 20, and the rope hole 33 is respectively provided at the guide groove 32. The groove 32 is connected to the limit groove 22, and the front end of the traction rope 30 is passed around the outer circumference of the guide wheel 28, and is connected to the slider 24 after passing through the rope hole 33. When the rotating handle 31 is rotated clockwise, the traction rope 30 is reeled in, and the traction rope 30 will apply a pulling force to the slider 24 away from the power hydraulic rod 15. The slider 24 drives the outer moving plate 21 to move in the direction away from the power hydraulic rod 15. During this process, the return spring 26 is stretched. When the outer moving plate 21 moves to contact the inclined surface of the positioning plate 20, the hydraulic valve naturally falls, and the outer moving plate 21 is no longer subjected to the pressure of the hydraulic valve, so that the slider 24 drives the outer moving plate 21 to reset under the action of the restoring force of the return spring 26. During the resetting process of the slider 24, the traction rope 30 is re-stretched by the slider 24 and returns to its initial state.

[0033] When the positioning component is in use, the power hydraulic rod 15 is first controlled to extend toward the mounting plate 1, so that the bottom support plate 16 enters the matching groove 4, and then the hydraulic valve is placed on the bottom support plate 16, and the power hydraulic rod 15 is controlled to retract upward to lift the hydraulic valve to contact with the upper clamping plate 18, and the upper clamping plate 18 cooperates with the bottom support plate 16 to form a stable clamping for the hydraulic valve, and then the driving motor 13 can be controlled to operate according to needs, and the relative position of the slide seat 11 and the displacement screw 12 can be adjusted, and then the position of the hydraulic valve clamping mechanism 9 can be adjusted, and then the push frame 3 can be pushed according to needs. Push and adjust the position of the pushing frame 3 relative to the horizontal slide groove 7, so that the hydraulic valve clamping mechanism 9 reaches the specified height position; then, by rotating the rotating handle 31, the traction rope 30 applies tension to the slider 24, and the slider 24 drives the outer moving plate 21 to move until the outer moving plate 21 is changed to an inclined state, and the hydraulic valve above the outer moving plate 21 naturally falls to the specified height position for easy installation; then the slider 24 is subjected to the restoring force of the return spring 26, which will drive the outer moving plate 21 to reset. If the next hydraulic valve needs to be transferred, repeat the above operation.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
