Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic valve core processing, and in particular to a hydraulic valve core fixture. Background Technology

[0002] A car damper is a device that improves the shock absorption performance of a vehicle by utilizing the shock absorption function of a hydraulic spring. Its main purpose is to make driving more comfortable. It is equipped with a hydraulic valve, and the valve core is one of the most critical components of the hydraulic valve, which is mainly used for pressure control.

[0003] Because the valve core is small and requires multiple through holes, a clamp is needed to hold and fix its surface during processing. In the prior art, utility model patent CN218575543U discloses a hydraulic valve core clamp, including a base, a support plate, and a fixing frame. The support plate is welded and fixed to the middle of the upper surface of the base, and the fixing frame is welded and fixed to the right side of the upper surface of the base. The fixing frame has a U-shaped frame structure and is also equipped with movable clamping components for clamping the upper end of the valve core. Through the support plate and the corresponding lead screw, lifting plate, and clamping ring, the hydraulic valve core can be vertically clamped and fixed, and the clamping ring can be quickly replaced. This facilitates clamping valve cores of different sizes and models without obstructing the valve core surface and affecting its normal processing.

[0004] However, the above-mentioned patented solutions also have certain drawbacks. When machining holes at different positions on the surface of the valve core, it is necessary to loosen the clamping of the valve core, then rotate the valve core to expose the corresponding part of the outer wall of the valve core, and then clamp the valve core back in place before machining holes at different positions on the surface of the valve core. The repeated clamping and loosening makes it inconvenient to machine holes at different positions on the surface of the valve core, affecting the efficiency of machining holes on the surface of the valve core and making it impractical. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a hydraulic valve core fixture that makes it easier to process holes at different positions on the valve core surface, effectively improves the processing efficiency of hole opening on the valve core surface, and enhances practicality.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic valve core clamp, comprising a base, a clamping mechanism, and a limiting mechanism. The clamping mechanism includes a fixed frame and a holding cylinder. The fixed frame is fixedly connected to one side of the top of the base. An adjusting screw is rotatably mounted on the base and the fixed frame. A turning wheel is fixedly mounted on the top of the adjusting screw. A transmission plate is screwed onto the adjusting screw, and the transmission plate is slidably mounted on the base. A fixing ring is integrally fixed on the transmission plate, and a T-shaped wheel is rotatably mounted on the fixing ring. The device has a threaded hole in the middle and threads on the outer wall of the pressure cylinder. The pressure cylinder is screwed onto the T-shaped wheel. The top of the base has a recessed groove, on which a clamping plate is rotatably mounted. The limiting mechanism includes an L-shaped bracket, which is fixedly welded to the transmission plate. A T-shaped cylindrical limiting pin is slidably mounted on the L-shaped bracket. A spring is sleeved on the T-shaped cylindrical limiting pin, and the two ends of the spring are fixedly connected to the L-shaped bracket and the T-shaped cylindrical limiting pin, respectively. The T-shaped wheel has multiple sets of limiting holes arranged in a ring, and the T-shaped cylindrical limiting pin is inserted into one set of limiting holes.

[0008] Preferably, the top of the fixed ring is provided with a mounting groove, and the bottom of the T-shaped wheel is integrally fixed with a limiting platform. The T-shaped wheel is rotatably mounted on the fixed ring by cooperating with the mounting groove. The top of the T-shaped wheel is horizontal with the top of the fixed ring, the limiting platform at the bottom of the T-shaped wheel abuts against the bottom of the fixed ring, and the T-shaped cylindrical limiting pin is inserted into the limiting hole, with the bottom of the T-shaped cylindrical limiting pin abutting against the bottom of the mounting groove.

[0009] Preferably, the transmission plate is symmetrically provided with two sets of limiting sliders, the two sets of limiting sliders are integral with the transmission plate, and the inner walls on both sides of the fixed frame are provided with sliding grooves that cooperate with the limiting sliders. The transmission plate is slidably installed on the fixed frame through the cooperation of the limiting sliders and the sliding grooves.

[0010] Preferably, a pressure ring is fixedly sleeved on the outer wall of the pressure holding cylinder, the pressure ring is located at the upper edge of the thread on the outer wall of the pressure holding cylinder, and multiple pressure holding cylinders are provided, with the multiple pressure holding cylinders having the same outer diameter and different inner diameters.

[0011] Preferably, a T-shaped handle is fixedly connected to the top of the pressure-holding cylinder.

[0012] Preferably, an anti-slip rubber pad is fixedly connected to the top of the clamping plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the valve core to be processed is placed on the clamping plate. Then, the adjusting screw is rotated by the screw wheel, causing the adjusting screw to move the transmission plate downwards. The transmission plate then moves the fixing ring and the T-shaped wheel downwards, causing the T-shaped wheel to move the holding cylinder downwards. This allows the bottom of the holding cylinder to gradually press against the top of the valve core. The screw wheel is then rotated further to press the holding cylinder firmly against the top of the valve core. The valve core is then clamped and fixed by the holding cylinder and the clamping plate, allowing for hole drilling. During processing, if it is necessary to adjust the surface machining position of the valve core, one hand pulls up the T-shaped cylindrical limiting pin, causing it to disengage from the limiting hole. The spring is stretched, releasing the limiting effect on the T-shaped wheel. Then, the other hand holds the valve core and... Rotation allows for adjustment of the machining position on the valve core surface. Because the clamping sleeve and chuck tightly hold the valve core, rotation causes the valve core to drive the T-shaped wheel to rotate via the clamping sleeve, and the chuck rotates accordingly. When the valve core reaches the appropriate position, the corresponding limiting hole aligns with the T-shaped cylindrical limiting pin. Then, the T-shaped cylindrical limiting pin is released, allowing it to re-insert into the limiting hole under spring return, thus re-limiting the T-shaped wheel and preventing it from rotating. Machining can then be performed at the adjusted position on the valve core surface. During adjustment, there is no need to repeatedly loosen and tighten the valve core, making it easier to machine holes at different positions on the valve core surface, effectively improving machining efficiency and practicality.

[0021] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] Example

[0023] Please see Figures 1-6This utility model discloses a hydraulic valve core clamp, comprising a base 1, a fixing frame 2 fixedly connected to one side of the top of the base 1, an adjusting screw 3 rotatably mounted on the base 1 and the fixing frame 2, a turning wheel 4 fixedly mounted at the top of the adjusting screw 3, a transmission plate 5 screwed onto the adjusting screw 3, and the transmission plate 5 slidably mounted on the base 1, a fixing ring 6 integrally fixed on the transmission plate 5, a T-shaped wheel 7 rotatably mounted on the fixing ring 6, the T-shaped wheel 7 having a threaded hole in the middle, a pressure holding cylinder 8 having threads on its outer wall, and the pressure holding cylinder 8 screwed onto the T-shaped wheel 7, a countersunk groove at the top of the base 1, a clamping plate 9 rotatably mounted on the countersunk groove, and an L-shaped bracket 10 fixedly welded to the transmission plate 7. On plate 5, a T-shaped cylindrical limiting pin 11 is slidably mounted on the L-shaped bracket 10. A spring 12 is fitted on the T-shaped cylindrical limiting pin 11, and the two ends of the spring 12 are fixedly connected to the L-shaped bracket 10 and the T-shaped cylindrical limiting pin 11, respectively. Multiple sets of limiting holes 13 are arranged in a circular array on the T-shaped wheel 7, and the T-shaped cylindrical limiting pin 11 is inserted into one set of limiting holes 13. In use, the valve core to be processed is placed on the clamping plate 9, and then the adjusting screw 3 is rotated by the screw wheel 4, causing the adjusting screw 3 to drive the transmission plate 5 downwards. The transmission plate 5 drives the fixing ring 6 and the T-shaped wheel 7 downwards, causing the T-shaped wheel 7 to drive the pressure cylinder 8 downwards, thereby causing the pressure cylinder 8 to... The bottom gradually presses against the top of the valve core. Then, continue rotating the screw wheel 4 to press the pressure sleeve 8 tightly against the top of the valve core. The valve core is then clamped and fixed by the pressure sleeve 8 and the clamping plate 9, allowing for drilling. During machining, if it is necessary to adjust the machining position of the valve core surface, use one hand to pull up the T-shaped cylindrical limit pin 11, causing it to disengage from the limit hole 13. The spring 12 is stretched, releasing the limit on the T-shaped wheel 7. Then, use the other hand to hold the valve core and rotate it to adjust the machining position of the valve core surface. Because the pressure sleeve 8 and the clamping plate 9 tightly clamp the valve core, when rotating the valve core, the valve core will pass through the pressure sleeve 8... The T-shaped wheel 7 rotates, and the clamping plate 9 also rotates accordingly. When the valve core rotates to the appropriate position, the limiting hole 13 at the corresponding position is aligned with the T-shaped cylindrical limiting pin 11. Then, the T-shaped cylindrical limiting pin 11 is released, and under the rebound action of the spring 12, the T-shaped cylindrical limiting pin 11 is inserted into the limiting hole 13 at that position, re-limiting the T-shaped wheel 7 so that the T-shaped wheel 7 stops rotating. Thus, processing can be carried out at the adjusted position on the valve core surface. During the adjustment process, there is no need to repeatedly loosen and tighten the valve core, which makes it more convenient to process holes at different positions on the valve core surface, effectively improving the processing efficiency of holes on the valve core surface and enhancing practicality.

[0024] The fixed ring 6 has a mounting groove at its top, and the T-shaped wheel 7 has an integrally fixed limiting platform at its bottom. The T-shaped wheel 7 is rotatably mounted on the fixed ring 6 through cooperation with the mounting groove. The top of the T-shaped wheel 7 is horizontal with the top of the fixed ring 6, and the limiting platform at the bottom of the T-shaped wheel 7 abuts against the bottom of the fixed ring 6. The T-shaped cylindrical limiting pin 11 is inserted into the limiting hole 13, and the bottom of the T-shaped cylindrical limiting pin 11 abuts against the bottom of the mounting groove. When the T-shaped wheel 7 rotates, the limiting platform at the bottom of the T-shaped wheel 7 ensures that the T-shaped wheel 7 can only rotate within the mounting groove of the fixed ring 6 and will not slide vertically, thus improving the stability of the rotation of the T-shaped wheel 7.

[0025] Two sets of limiting sliders 14 are symmetrically provided on the transmission plate 5. The two sets of limiting sliders 14 are integral with the transmission plate 5. Slide grooves are provided on both sides of the inner wall of the fixing frame 2 to cooperate with the limiting sliders 14. The transmission plate 5 is slidably installed on the fixing frame 2 through the cooperation of the limiting sliders 14 and the slide grooves. Through the cooperation of the limiting sliders 14 and the slide grooves, the transmission plate 5 moves more smoothly and reliably when moving up and down.

[0026] A pressure ring 16 is fixedly sleeved on the outer wall of the pressure holding cylinder 8. The pressure ring 16 is located at the upper edge of the thread on the outer wall of the pressure holding cylinder 8, and there are multiple pressure holding cylinders 8. The multiple pressure holding cylinders 8 have the same outer diameter and different inner diameter. When installing the pressure holding cylinder 8, the pressure holding cylinder 8 is screwed into the threaded hole of the T-shaped wheel 7, so that the pressure ring 16 is pressed against the top of the T-shaped wheel 7, and the bottom of the pressure holding cylinder 8 is exposed through the threaded hole. Through the cooperation between the pressure ring 16 and the T-shaped wheel 7, the pressure holding cylinder 8 is installed more securely. By setting multiple pressure holding cylinders 8, they can be replaced according to the size of the top of the valve core so that the pressure holding cylinder 8 can be adapted to clamp valve cores of different sizes.

[0027] The top of the pressure-holding cylinder 8 is fixedly connected to a T-shaped handle 15; by setting the T-shaped handle 15, the pressure-holding cylinder 8 can be more convenient to screw and disassemble, and the pressure-holding cylinder 8 can be disassembled and assembled manually without the aid of tools.

[0028] The top of the clamping plate 9 is fixedly connected to an anti-slip pad 17; by setting the anti-slip pad 17, the friction at the top of the clamping plate 9 can be increased, and slippage with the bottom of the valve core can be avoided when clamping the valve core.

[0029] This utility model discloses a hydraulic valve core clamp. In operation, the valve core to be processed is placed on the clamping plate 9. Then, the adjusting screw 3 is rotated by the turning wheel 4, causing the adjusting screw 3 to move the transmission plate 5 downwards. The transmission plate 5 then moves the fixing ring 6 and the T-shaped wheel 7 downwards, causing the T-shaped wheel 7 to move the holding cylinder 8 downwards. The bottom of the holding cylinder 8 gradually abuts against the top of the valve core. The turning wheel 4 is then rotated further to press the holding cylinder 8 firmly against the top of the valve core. The valve core is thus clamped and fixed by the holding cylinder 8 and the clamping plate 9, allowing for hole drilling. During processing, if the surface machining position of the valve core needs adjustment, the T-shaped cylindrical limit pin 11 is pulled up by one hand, causing the T-shaped cylindrical limit pin 11 to move from its limit position. The valve core is disengaged from hole 13, and spring 12 is stretched, releasing the limit on T-shaped wheel 7. Then, the valve core is held and rotated with the other hand, allowing adjustment of the machining position on the valve core surface. Since the holding cylinder 8 and chuck 9 tightly hold the valve core, when the valve core is rotated, the valve core will drive T-shaped wheel 7 to rotate through the holding cylinder 8, and chuck 9 will also rotate. When the valve core rotates to the appropriate position, the limiting hole 13 at the corresponding position is aligned with the T-shaped cylindrical limiting pin 11. Then, the T-shaped cylindrical limiting pin 11 is released, allowing it to insert into the limiting hole 13 at that position under the rebound action of spring 12, re-limiting T-shaped wheel 7 and preventing it from rotating. Thus, machining can be performed at the adjusted position on the valve core surface.

[0030] The hydraulic valve core clamp of this utility model can be installed, connected or set in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
