Description

Technical Field

[0001] This utility model relates to the field of pressure compensation valve technology, and in particular to an adjustable pressure compensation valve clamping fixture. Background Technology

[0002] An adjustable pressure compensation valve is a control element used in hydraulic systems. Its main function is to stabilize system pressure while allowing dynamic adjustment of compensation parameters according to working conditions. Its core feature is that the pressure setpoint can be changed through the adjustment mechanism to adapt to different loads or flow changes, thereby ensuring the stability of the actuator's operation.

[0003] Adjustable pressure compensation valves include components such as valve body, valve core, spring, and sealing assembly. However, during the assembly process of adjustable pressure compensation valves, the valve body cannot be quickly fixed, resulting in a long assembly cycle and reduced assembly efficiency. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the prior art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0022] Reference Figures 1-4 An adjustable pressure compensation valve clamping fixture includes a base plate 12. A placement plate 8 is connected to the upper surface of the base plate 12 via a translation assembly. A U-shaped frame 7 is bolted to the upper surface of the placement plate 8. Two guide frames 10 are bolted to the inner top wall of the U-shaped frame 7. A U-shaped slider 23 is slidably connected to the outer side of each guide frame 10. A connecting rod 3 is welded to the bottom of each U-shaped slider 23, and a clamping plate 4 is welded to the bottom end of each connecting rod 3. Alternating racks 16 are bolted to the opposite sides of each U-shaped slider 23. The inner top wall of the U-shaped frame 7... A rotating shaft 21 is rotatably connected via a bearing. A gear 22 is keyed to the outside of the rotating shaft 21. The gear 22 is located between two guide frames 10 and between two racks 16, meshing with the two racks 16. When fixing is required, the two U-shaped sliders 23 drive the two clamping plates 4 to move towards each other through the connecting block 14, thereby clamping and fixing the valve body of the adjustable pressure compensation valve. This allows for quick fixing of the valve body of the adjustable pressure compensation valve, facilitating the assembly of the adjustable pressure compensation valve by the staff, saving time and improving efficiency.

[0023] In this invention, the top of the U-shaped frame 7 is equipped with a power assembly that drives one of the U-shaped sliders 23 to move. The power assembly includes a cylinder 5, which is a self-locking cylinder, model CDLQA80-100DC-B. The cylinder 5 is fixed to the top outer wall of the U-shaped frame 7 by bolts. A horizontal groove 1 is opened on the top of the U-shaped frame 7, and a connecting block 14 is slidably connected in the horizontal groove 1. The telescopic rod of the cylinder 5 is fixed to the connecting block 14, and the connecting block 14 is fixed to one of the U-shaped sliders 23. When the cylinder 5 is activated to retract, the cylinder 5 will drive the connecting block 14 to move along the horizontal groove 1. As the connecting block 14 moves, one of the U-shaped sliders 23 moves horizontally along the guide frame 10. One of the U-shaped sliders 23 moves the rack 16 connected to it. The rack 16 drives the gear 22 to rotate. The gear 22 drives the other rack 16 to move, thereby moving the other U-shaped slider 23 along the guide frame 10. The two U-shaped sliders 23 move towards each other through the connecting block 14 and are locked by the self-locking function of the cylinder 5, so that the clamping plates 4 stably clamp the valve body of the adjustable pressure compensation valve.

[0024] Specifically, the translation component includes a threaded sleeve 9, a guide groove on the upper surface of the base plate 12, the threaded sleeve 9 being slidably connected within the guide groove, a placement plate 8 welded to the top of the threaded sleeve 9, a threaded rod 11 rotatably connected within the guide groove via bearings, the threaded rod 11 passing through the threaded sleeve 9 and threadedly connected to it, a corrugated cover positioned above the threaded rod 11 within the guide groove, with both ends of the corrugated cover fixed to the threaded sleeve 9 and the base plate 12 respectively, a motor 17 being bolted to one side of the base plate 12, and one end of the output shaft of the motor 17 passing through the base plate 12 and fixed to the threaded rod 11, the motor 17 being a self-locking motor, model S87DT160M4. Two sliding grooves 13 are provided on the upper surface of plate 12. Two sliders that move along the groove direction of sliding groove 13 are welded to the bottom of the placement plate 8. The two sliding grooves 13 are located on both sides of the guide groove. After clamping, the motor 17 can be started to drive the threaded rod 11 to rotate. The threaded rod 11 will move along the guide groove by engaging with the threaded sleeve 9. The threaded sleeve 9 will drive the placement plate 8 to move, thereby moving the horizontal position of the clamped adjustable pressure compensation valve body, which is convenient for the operator to use and improves the use effect of the clamping fixture. The horizontal position of the adjustable pressure compensation valve body is fixed by the self-locking function of the motor 17.

[0025] The guide frame 10 includes two fixing blocks 20, both of which are welded to the top inner wall of the U-shaped frame 7. Two guide rods 18 are welded between the two fixing blocks 20, and the guide rods 18 pass through the U-shaped slider 23. The U-shaped slider 23 moves horizontally along the guide rods 18 inside the guide frame 10, thereby guiding the movement of the U-shaped slider 23.

[0026] Working principle: When fixation is required, the valve body of the adjustable pressure compensation valve is placed on the placement plate 8, and then the cylinder 5 is activated to retract. The cylinder 5 will drive the connecting block 14 to move along the transverse groove 1. The connecting block 14 will drive one of the U-shaped sliders 23 to move horizontally along the guide frame 10. One of the U-shaped sliders 23 will drive the rack 16 connected to it to move. The rack 16 will drive the gear 22 to rotate. The gear 22 will drive the other rack 16 to move, thereby causing the other U-shaped slider 23 to move along the guide frame 10. The two U-shaped sliders 23 will drive the two clamping plates 4 to move towards each other through the connecting block 14, thereby causing the two clamping plates 4 to clamp and fix the two flange end faces of the pressure compensation valve.

[0027] Then, the self-locking function of cylinder 5 is used to lock the valve body of the adjustable pressure compensation valve, so that the clamping plate 4 can stably clamp the valve body of the adjustable pressure compensation valve. This allows the valve body of the adjustable pressure compensation valve to be fixed quickly, making it easier for the operator to assemble the adjustable pressure compensation valve, saving time and improving efficiency. After clamping is completed, motor 17 can be started to drive threaded rod 11 to rotate. Threaded rod 11 engages with threaded sleeve 9, causing threaded sleeve 9 to move along the guide groove. Threaded sleeve 9 will drive the placement plate 8 to move, thereby moving the horizontal position of the clamped adjustable pressure compensation valve body, making it easier for the operator to use and improving the effectiveness of the clamping fixture.

[0028] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
