Technical Field
[0001] The utility model relates to the technical field of valve adjustment tools, in particular to a hydraulic valve adjustment tool. Background Art
[0002] Hydraulic valves are commonly used in the field of mechanical equipment automation control. They use pressurized oil as a power transmission medium to drive key components of mechanical equipment. At present, some hydraulic valves have an adjustment hole inside the valve mouth, which is inserted into the adjustment hole by an external workpiece, and then the workpiece is used to apply force to the adjustment hole to rotate the valve mouth of the hydraulic valve, thereby adjusting the valve mouth opening of the hydraulic valve. For this type of hydraulic valve, there are currently no professional tools to adjust the valve mouth opening. This means that every time the hydraulic valve opening is adjusted, it is necessary to find an ordinary and common basic workpiece to replace the professional tool to rotate the inside of the valve mouth. For example, the simplest method is to insert a screwdriver into the hole, and then use the screwdriver to push the inside of the valve mouth. This solution has technical problems such as difficult operation and complicated process. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0024] In the description of the present application, “plurality” means two or more than two, unless otherwise clearly and specifically defined.
[0025] It should also be noted that the directional terms such as left, right, up and down in the embodiments of the present application are merely relative concepts or are based on the normal use status of the product, and should not be considered as restrictive.
[0026] See also Figure 1-Figure 5 The hydraulic valve adjustment tool of this embodiment includes a sleeve head 10 and an operating rod 20. The sleeve head 10 can be plugged into the valve mouth of the hydraulic valve, and the purpose is to fix the hydraulic valve adjustment tool with the valve mouth of the hydraulic valve through the sleeve head 10, so that the relative position of the hydraulic valve adjustment tool and the valve mouth of the hydraulic valve is fixed, so as to avoid the hydraulic valve adjustment tool from shaking significantly during the subsequent adjustment of the opening of the hydraulic valve mouth, thereby affecting the adjustment process. Specifically, the sleeve head 10 is a hollow column, and the sleeve head 10 can be sleeved on the outside of the valve mouth of the hydraulic valve. Of course, the sleeve head 10 can also be inserted into the inside of the valve mouth of the hydraulic valve, as long as the sleeve head 10 can be fixedly connected to the valve mouth of the hydraulic valve.
[0027] The operating rod 20 includes an adjustment end 21 that can move axially along the sleeve head 10 and is rotatably inserted into the sleeve head 10, and an operating end 22 that is exposed from the sleeve head 10. At least one adjustment column 60 is convexly provided on the side of the adjustment end 21 that is away from the operating end 22. The adjustment column 60 is extended in a direction parallel to the rotation axis 50 of the adjustment end 21, and the direction in which the adjustment column 60 is extended is staggered from the rotation axis 50 of the adjustment end 21. Preferably, the number of adjustment columns 60 configured in this embodiment is six, and the six adjustment columns 60 are arranged at equal intervals around the axis of the adjustment end 21, and each adjustment column 60 corresponds to an adjustment hole in the internal structure of the valve nozzle of the hydraulic valve.
[0028] The working process of this embodiment includes: the operator inserts the sleeve head 10 into the valve nozzle of the hydraulic valve, so that the hydraulic valve adjustment tool is fixed to the valve nozzle of the hydraulic valve. Then the operator manually pushes the operating end 22 to move the operating rod 20 toward the inside of the valve nozzle of the hydraulic valve, so that the adjustment end 21 moves along the axial direction of the sleeve head 10 from the first position (such as Figure 1 and Figure 2 ) moves to a second position (as shown) in the sleeve head 10 Figure 3 and Figure 4 As shown in the figure), until the adjusting column 60 is inserted into the assembly hole inside the valve nozzle of the hydraulic valve. Finally, the operator rotates the operating end 22, thereby driving the adjusting end 21 to rotate, and the adjusting end 21 drives the adjusting column 60 to rotate around the rotation axis of the adjusting end 21, and the adjusting rod drives the internal structure of the valve nozzle of the hydraulic valve to rotate, thereby adjusting the opening of the valve nozzle of the hydraulic valve.
[0029] This embodiment provides a tool specifically for adjusting the opening of the hydraulic valve orifice in the aforementioned manner. The operator can adjust the opening of the hydraulic valve orifice only by operating the operating lever 20, so that the operator can easily adjust the oil pressure of the hydraulic valve. The operation process is simple and convenient, which solves the technical problems of difficult operation and complicated process in the prior art.
[0030] Next, the structure of the hydraulic valve adjusting tool of this embodiment is further described.
[0031] In a feasible embodiment, the hydraulic valve adjustment tool further includes a locking structure 30. The locking structure 30 is formed between the sleeve head 10 and the adjustment end 21. When the adjustment end 21 is pushed from a first position in the sleeve head 10 along the axial direction of the sleeve head 10 to a second position in the sleeve head 10 by the operating rod 20, the locking structure 30 rotatably limits the adjustment end 21 to the second position, thereby improving the rotation stability of the adjustment end 21.
[0032] In a feasible embodiment, the locking structure 30 includes a first groove 33, a second groove 31 and a ball 32. The first groove 33 is opened on the inner wall of the sleeve head 10, and the second groove 31 is opened on the side of the adjustment end 21 facing the inner wall of the sleeve head 10. The ball 32 is located between the inner wall of the sleeve head 10 and the adjustment end 21. The ball 32 is rollably arranged in the first groove 33, and is partially exposed outside the first groove 33. Under the limitation of the inner wall of the sleeve head 10, the ball 32 will not be separated from the first groove 33. Specifically, the part of the ball 32 exposed in the first groove 33 abuts against the inner wall of the sleeve head 10, so that there is a certain extrusion force between the inner wall of the sleeve head 10 and the ball 32, and the extrusion force confines the ball 32 in the first groove 33 and does not separate from the first groove 33.
[0033] When the adjusting end 21 is pushed from the first position to the second position, the first groove 33 drives the ball 32 to move toward the second groove 31. In this process, the ball 32 abuts against the inner wall of the sleeve head 10, and the ball 32 can roll along the inner wall of the sleeve head 10, thereby reducing the friction between the ball 32 and the sleeve head 10, and further reducing the resistance generated by the relative movement of the adjusting end 21 and the sleeve head 10. When the adjusting end 21 moves to the second position, the part of the ball 32 exposed in the first groove 33 enters the second groove 31. At this time, the ball 32 can roll freely between the first groove 33 and the second groove 31, but will not be separated from the first groove 33 and the second groove 31. The opposite sides of the ball 32 are respectively located in the first groove 33 and the second groove 31, thereby interfering with the relative movement of the adjusting end 21 and the sleeve head 10 along the axial direction of the sleeve head 10, so as to prevent the relative movement of the adjusting end 21 and the sleeve head 10 along the axial direction of the sleeve head 10, thereby limiting the adjusting end 21 to the second position.
[0034] In order to enable the adjustment end 21 to rotate relative to the sleeve head 10 at the second position, the solution provided in this embodiment includes: the first groove 33 is a hemispherical groove, and the second groove 31 is an annular groove. When the adjustment end 21 rotates relative to the sleeve head 10, one side of the ball 32 is confined in the first groove 33, and the other side of the ball 32 can move or roll along the circumferential direction of the second groove 31. In this way, on the one hand, the ball 32 will not interfere with the relative rotation process of the adjustment end 21 and the sleeve head 10. On the other hand, the second groove 31 guides the ball 32, thereby guiding the rotation process of the adjustment end 21, thereby improving the stability of the rotation of the adjustment end 21.
[0035] Of course, the shapes of the first groove 33 and the second groove 31 are interchanged, the first groove 33 is set as an annular groove, and the second groove 31 is set as a hemispherical groove. Such a scheme should be understood as an equivalent scheme to the scheme of this embodiment.
[0036] In another embodiment, the first groove 33 is an annular groove extending circumferentially along the sleeve head 10; the second groove 31 is an annular groove extending circumferentially along the adjustment end 21. Such a solution can also realize relative rotation between the adjustment end 21 and the sleeve head 10.
[0037] In a feasible embodiment, the hydraulic valve adjustment tool further includes an elastic component 40, the elastic component 40 connects the adjustment end 21 and the sleeve head 10, and the elastic component 40 uses its own deformation elastic force to form a tendency to force the adjustment end 21 to move to the first position. Specifically, when the adjustment end 21 is located at the second position, the elastic component 40 is squeezed or stretched by the adjustment end 21 and the sleeve head 10, so that the elastic component 40 undergoes elastic deformation, thereby generating deformation elastic force. Under the action of the deformation elastic force, the adjustment end 21 is subjected to the preload force, and the adjustment end 21 applies force to the ball 32 through the second groove 31, so that the ball 32 is closely attached to the side wall of the first groove 33 of the sleeve head 10, so that during the relative rotation of the adjustment end 21 and the sleeve head 10, the ball 32 is always closely attached to the corresponding side wall of the first groove 33 and the corresponding side wall of the second groove 31 on the opposite sides of the sleeve head 10 in the axial direction, so as to avoid the corresponding side wall of the first groove 33 and the corresponding side wall of the second groove 31 from detaching from the surface of the ball 32 and causing jumping during the relative rotation of the sleeve head 10 and the adjustment end 21, so that the relative rotation process of the sleeve head 10 and the adjustment end 21 is smoother. Furthermore, the elastic component 40 can also play a buffering role in the process of the adjustment end 21 moving along the axial direction of the sleeve head 10.
[0038] In a feasible embodiment, the elastic component 40 includes a card plate 43, a spring 42 and a card block 41; the card plate 43 is clamped in the port of the sleeve head 10, and a through hole (not shown in the figure) is opened for the adjustment end 21 to pass through. The adjustment end 21 can be inserted back and forth through the through hole. The card block 41 is arranged on the side of the adjustment end 21 facing the inner wall of the sleeve head 10, the spring 42 is sleeved on the adjustment end 21, and is located between the card plate 43 and the card block 41, and the two ends of the spring 42 are respectively connected to the card plate 43 and the card block 41. When the adjustment end 21 moves from the first position to the second position, the adjustment end 21 drives the card block 41 to move toward the card plate 43, and the card block 41 squeezes the spring 42, so that the spring 42 is squeezed to generate a deformation elastic force. Under the action of the deformation elastic force, the adjustment end 21 has a tendency to move toward the first position, but under the clamping action of the ball 32, the first groove 33, and the second groove 31, the tendency of the adjustment end 21 to move toward the first position is overcome. In one application scenario, after the valve mouth opening of the hydraulic valve is adjusted, the operator can pull the operating rod 20. Under the combined action of the operator's pulling force and the deformation elastic force of the spring 42, the adjusting end 21 overcomes the blocking effect of the ball 32, the first groove 33, and the second groove 31, and the adjusting end 21 moves back to the first position and returns to its original position.
[0039] In a feasible embodiment, a step portion 11 is formed on the inner wall of the port of the sleeve head 10, and the step portion 11 is arranged around the inner wall of the sleeve head 10. The plate surface of the clamping plate 43 is perpendicular to the axis of the sleeve head 10, and the edge of the side wall of the clamping plate 43 facing away from the clamping block 41 abuts against the step portion 11. The spring 42 is connected to the clamping plate 43, so that the clamping plate 43 is confined between the spring 42 and the step portion 11. Preferably, the clamping plate 43 is fixedly connected to the step portion 11, and the two ends of the spring 42 are respectively fixed to the clamping plate 43 and the clamping block 41, so that the adjustment end 21 can be connected to the sleeve head 10 through the clamping block 41, the spring 42 and the clamping plate 43 to prevent the adjustment end 21 from being separated from the sleeve head 10.
[0040] In other embodiments, the two ends of the spring 42 can respectively abut the clamping plate 43 and the block 41. Since the ball 32 forms a limiting effect on the block 41, the block 41 is prevented from moving below the ball 32 (the bottom shown in the figure). This method can also limit the movement range of the block 41, thereby preventing the adjustment end 21 from detaching from the sleeve head 10.
[0041] Please combine Figure 5 In a feasible implementation, the adjustment end 21 is provided with an assembly hole, and one end of the adjustment column 60 is inserted into the assembly hole. During assembly, different types of adjustment columns 60 can be selected according to actual needs, so that different types of hydraulic valves can be adjusted.
[0042] In a feasible implementation, the adjusting column 60 is interference fit with the assembly hole. Specifically, during assembly, the adjusting column 60 is first assembled in the assembly hole by liquid nitrogen cooling, and when the temperature returns to normal, the adjusting column 60 expands due to heat, so that the adjusting column 60 squeezes the inner wall of the assembly hole to form an interference fit.
[0043] The embodiment disclosed in this specification is only an example of the unilateral features of the utility model, and the protection scope of the utility model is not limited to this embodiment. Any other functionally equivalent embodiments fall within the protection scope of the utility model. For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all these changes and deformations should fall within the protection scope of the claims of the utility model.
