Description
Technical Field
[0001] This utility model relates to the field of hydraulic valve block clamping technology, specifically an adjustable clamping fixture for hydraulic valve blocks. Background Technology
[0002] A hydraulic valve block is a complex functional block that houses various hydraulic components and allows these components to communicate with each other through internal channels. It is a key component in a hydraulic transmission system.
[0003] The fixture used in the machining of hydraulic valve blocks can constrain the position of the workpiece, ensuring that the dimensional accuracy and geometric tolerances of processes such as drilling and milling meet the standards; it can offset the cutting force during the machining process, avoiding machining errors caused by workpiece vibration or displacement; at the same time, it can ensure operational safety and prevent workpiece loosening from causing equipment collisions or personnel accidents.
[0004] Existing fixtures clamp and fix hydraulic valve blocks by placing the hydraulic valve block on the worktable for clamping and fixing, and then processing it through the upper processing device. However, when adjusting the working surface of the valve block, it is necessary to clamp it again to switch the working surface.
[0005] Therefore, an adjustable fixture for hydraulic valve blocks is proposed to address the above problems. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: An adjustable clamp for a hydraulic valve block, comprising a worktable, a pair of upright plates fixedly connected to the top of the worktable; a cylinder fixedly connected to the side wall of the upright plate; a round rod fixedly connected to the output end of the cylinder; the round rod being slidably connected to the upright plate; a support frame fixedly connected to the end of the round rod; a motor fixedly connected to the middle of the support frame; a clamping plate fixedly connected to the output end of the motor; multiple limiting plates fixedly connected to the inner wall of the clamping plate; and a hydraulic valve block body disposed between the limiting plates. By using the clamping plate and limiting plates to clamp the hydraulic valve block body, the clamping plate can reduce the obstruction of the working area of the hydraulic valve block body surface, thereby reducing the impact on processing. Simultaneously, the motor can drive the hydraulic valve block body to rotate, allowing it to quickly switch working surfaces during processing, thereby rapidly adjusting the working surface of the hydraulic valve block body.
[0008] Preferably, a hydraulic cylinder is fixedly connected to the middle of the workbench; a placement plate is fixedly connected to the top of the hydraulic cylinder; by adding a hydraulic cylinder and a placement plate, the hydraulic valve block body can be continuously lifted by the hydraulic cylinder when placing the hydraulic valve block body, thereby increasing the convenience of placing the hydraulic valve block body between the clamping plate.
[0009] Preferably, the top of the placement plate has a placement groove; a positioning plate is fixedly connected to the middle of the placement groove; the positioning plate is higher than the hydraulic cylinder, and the distance between the higher part and the contact between the placement plate and the clamping plate is consistent; by adding the positioning plate, the distance between the placement plate and the clamping plate can be compensated when clamping the hydraulic valve block body, thereby accelerating the clamping speed when clamping the clamping plate, and reducing the impact of the placement plate on the clamping plate.
[0010] Preferably, a pair of pull rods are fixedly connected to the bottom of the placement plate; the pull rods are through-mounted and slidably connected to the worktable; a baffle is fixedly connected to the bottom of the pull rods; the baffle can provide a prompt when the placement plate is raised, so that it can be automatically stopped when it moves to the optimal position, and the hydraulic cylinder can be stopped at this time without adjusting the position of the placement plate, thereby increasing the convenience when raising the hydraulic valve block body.
[0011] Preferably, a buffer pad is fixed to the top of the baffle; multiple buffer pads are provided on the baffle; by adding buffer pads, the baffle can be buffered when it comes into contact with the worktable, thereby reducing impact damage and increasing protection.
[0012] Preferably, a laser indicator light is fixed to one side wall of the upright plate; the laser indicator light is located at the contact position between the bottom of the placement plate and the clamping plate; by adding a laser indicator light, the distance between the baffle and the worktable can be intuitively judged, thereby increasing the prompt.
[0013] The advantages of this utility model are:
[0014] 1. The adjustable fixture for hydraulic valve blocks described in this utility model uses clamping plates and limiting plates to hold the hydraulic valve block body. When the clamping plates are used, they can block less of the working area of the hydraulic valve block body surface, thereby reducing the impact on processing. At the same time, the motor can also drive the hydraulic valve block body to rotate, so that it can quickly switch working surfaces during processing, thereby quickly adjusting the working surface of the hydraulic valve block body.
[0015] 2. The adjustable clamp for hydraulic valve blocks described in this utility model, by adding a hydraulic cylinder and a placement plate, allows for continuous lifting of the hydraulic valve block body during placement, thereby increasing the convenience of placing the hydraulic valve block body between the clamp and the plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, an adjustable clamp for a hydraulic valve block includes a workbench 1. A pair of upright plates 11 are fixedly connected to the top of the workbench 1. A cylinder 12 is fixedly connected to the side wall of the upright plate 11. A round rod 13 is fixedly connected to the output end of the cylinder 12. The round rod 13 is slidably connected to the upright plate 11. A support frame 14 is fixedly connected to the end of the round rod 13. A motor 15 is fixedly connected to the middle of the support frame 14. A clamping plate 16 is fixedly connected to the output end of the motor 15. A plurality of limiting plates 17 are fixedly connected to the inner wall of the clamping plate 16. A hydraulic valve block body 18 is arranged between the limiting plates 17. During operation, when clamping the hydraulic valve block body 18, the hydraulic valve block body 18 is first placed between the clamping plates 16. Then, the pair of cylinders 12 are simultaneously activated by the controller, causing the cylinders 12 to drive the round rod 13 to extend and retract. During the extension and retraction, the support frame 14 pushes the clamping plate 16 closer to the hydraulic valve block body 18. When the hydraulic valve block body 18 is clamped by a pair of clamping plates 16, the limiting plate 17 will be located on both sides of the hydraulic valve block body 18, blocking the four corners and closing the four sides. Subsequently, when it is necessary to change the working surface of the hydraulic valve block body 18 during processing, a pair of motors 15 can be started to rotate in the same direction. After rotation, the hydraulic valve block body 18 will rotate, and the working surface of the hydraulic valve block body 18 can be flipped to change the working surface, thereby adjusting the working surface of the hydraulic valve block body 18. By using clamping plates 16 and limiting plates 17 to clamp the hydraulic valve block body 18, the clamping plates 16 can block less of the working area of the hydraulic valve block body 18 surface, thereby reducing the impact on processing. At the same time, the motors 15 can also drive the hydraulic valve block body 18 to rotate, so that the working surface can be quickly changed during processing, thereby quickly adjusting the working surface of the hydraulic valve block body 18.
[0026] like Figures 1 to 5As shown, a hydraulic cylinder 2 is fixedly connected to the middle of the workbench 1; a placement plate 21 is fixedly connected to the top of the hydraulic cylinder 2; during operation, when the hydraulic valve block body 18 is placed between a pair of clamping plates 16, since the hydraulic valve block body 18 is relatively heavy, it can first be placed on the surface of the placement plate 21 to adjust its posture and align with the clamping plates 16, and then the hydraulic cylinder 2 is activated to drive the placement plate 21 to move upward. At this time, the hydraulic cylinder 2 will move the hydraulic valve block body 18 upward through the placement plate 21, and after moving upward, it will send the hydraulic valve block body 18 into the space between the clamping plates 16. This reduces the inconvenience of operating the hydraulic valve block body 18. The placement plate 21 can be raised until its top is level with the inner wall of the clamping plate 16. Then, when the clamping plate 16 moves to clamp the hydraulic valve block body 18, the inner wall of the clamping plate 16 will be in contact with the bottom of the hydraulic valve block body 18. As the hydraulic valve block body 18 gradually enters the clamping plate 16, the hydraulic cylinder 2 can be lowered to reduce its impact on the clamping plate 16, thereby clamping and fixing it. By adding the hydraulic cylinder 2 and the placement plate 21, the hydraulic cylinder 2 can continuously lift the hydraulic valve block body 18 when it is placed, thereby increasing the convenience of placing the hydraulic valve block body 18 to the clamping plate 16.
[0027] like Figures 4 to 5 As shown, the top of the placement plate 21 has a placement groove 3; a positioning plate 31 is fixedly connected to the middle of the placement groove 3; the positioning plate 31 is higher than the hydraulic cylinder 2, and the distance between the higher part and the placement plate 21 when it contacts the clamping plate 16 is consistent; during operation, the surface of the positioning plate 31 can be placed when the hydraulic valve block body 18 is placed, and it can be stopped when the hydraulic cylinder 2 drives the positioning plate 31 to rise to the level of the top of the placement plate 21 and the bottom of the clamping plate 16. Then, it can continue to move when the clamping plate 16 clamps the hydraulic valve block body 18. When clamping, the clamping plate 16 is not blocked by the placement plate 21. At the same time, when the clamping plate 16 contacts the hydraulic valve block body 18, it directly enters the bottom of the hydraulic valve block body 18. Therefore, the clamping plate 16 can completely clamp the hydraulic valve block body 18 without lowering the placement plate 21. By adding the positioning plate 31, the gap between the placement plate 21 and the clamping plate 16 can be compensated when clamping the hydraulic valve block body 18. This can speed up the clamping speed when clamping the clamping plate 16, thereby reducing the impact of the placement plate 21 on the clamping plate 16.
[0028] like Figures 1 to 5As shown, a pair of pull rods 4 are fixedly connected to the bottom of the placement plate 21; the pull rods 4 are through-mounted and slidably connected on the workbench 1; a baffle 41 is fixedly connected to the bottom of the pull rods 4; during operation, when the hydraulic cylinder 2 drives the placement plate 21 to rise and fall, the placement plate 21 will drive the pair of pull rods 4 to rise and fall. When the placement plate 21 rises to the designated position, the baffle 41 will contact the bottom of the workbench 1, which will prevent the placement plate 21 from continuing to rise and fall. Stopping at this point is the optimal position for the clamping plate 16 to hold the hydraulic valve block body 18; the baffle 41 can provide a prompt when the placement plate 21 is raised, so that it will automatically stop when it moves to the optimal position. At this point, stopping the hydraulic cylinder 2 will not require adjusting the position of the placement plate 21, thereby increasing the convenience of raising the hydraulic valve block body 18.
[0029] like Figure 5 As shown, a buffer pad 5 is fixed to the top of the baffle 41; multiple buffer pads 5 are provided on the baffle 41; during operation, when the baffle 41 and the worktable 1 come into contact, the buffer pad 5 will deform and spread outwards when impacted, thus spreading flat. When spreading flat, the impact force is distributed, thereby buffering the impact between the baffle 41 and the worktable 1; by adding buffer pads 5, the baffle 41 can be buffered when it comes into contact with the worktable 1, reducing impact damage and thus increasing protection.
[0030] like Figures 1 to 3 As shown, a laser indicator light 6 is fixed to the side wall of one side of the upright plate 11; the laser indicator light 6 is located at the bottom contact position of the placement plate 21 and the clamping plate 16; during operation, when the placement plate 21 moves to the optimal position, it will block the light emitted by the laser indicator light 6. At this time, the stopping time can be judged by observing the distance between the placement plate 21 and the laser indicator light 6, thereby reducing the direct impact between the baffle 41 and the worktable 1; by adding the laser indicator light 6, the distance between the baffle 41 and the worktable 1 can be judged intuitively, thereby increasing the prompt.
[0031] Working principle: When clamping the hydraulic valve block body 18, first place the hydraulic valve block body 18 between the clamping plates 16, and then simultaneously start a pair of cylinders 12 through the controller. The cylinders 12 drive the round rod 13 to extend and retract. During the extension and retraction, the support frame 14 pushes the clamping plates 16 closer to the hydraulic valve block body 18. When the hydraulic valve block body 18 is clamped by the pair of clamping plates 16, the limiting plates 17 are located on both sides of the hydraulic valve block body 18, blocking the four corners and closing the four sides. Subsequently, when it is necessary to change the working surface of the hydraulic valve block body 18 during processing, a pair of motors 15 can be started to rotate in the same direction. After rotation, the hydraulic valve block body 18 will rotate. After rotation, the hydraulic valve block body 18 can be rotated. The valve block body 18 is flipped over to switch its working surface, thereby adjusting the working surface of the hydraulic valve block body 18. The hydraulic valve block body 18 is placed between a pair of clamping plates 16. Due to its weight, it can first be placed on the surface of the placement plate 21 to adjust its posture and align with the clamping plates 16. Then, the hydraulic cylinder 2 is activated to move the placement plate 21 upwards. The hydraulic cylinder 2 then moves the hydraulic valve block body 18 upwards through the placement plate 21, sending it between the clamping plates 16. This reduces the inconvenience of operating the hydraulic valve block body 18. The process stops when the hydraulic cylinder 2 raises the placement plate 21 until its top is level with the inner wall of the clamping plates 16. When the clamping plate 16 moves to clamp the hydraulic valve block body 18, the inner wall of the clamping plate 16 will be in contact with the bottom of the hydraulic valve block body 18. As the hydraulic valve block body 18 gradually enters the clamping plate 16, the hydraulic cylinder 2 can be lowered to reduce its impact on the clamping plate 16, thus achieving clamping and fixation. When placing the hydraulic valve block body 18, the surface of the positioning plate 31 can be placed. The hydraulic cylinder 2 should raise the positioning plate 31 until the top of the placement plate 21 is level with the bottom of the clamping plate 16, at which point the movement stops. The clamping plate 16 can then continue to move while clamping the hydraulic valve block body 18. The clamping plate 16 will not be obstructed by the placement plate 21 when clamping the hydraulic valve block body 18. Simultaneously, the clamping plate 16 and the hydraulic valve block body 18... Upon contact, it directly enters the bottom of the hydraulic valve block body 18, thus allowing the clamping plate 16 to clamp the hydraulic valve block body 18 without needing to lower the placement plate 21. When the hydraulic cylinder 2 drives the placement plate 21 to rise and fall, the placement plate 21 will drive a pair of pull rods 4 to rise and fall. When the placement plate 21 rises to the designated position, the baffle 41 will contact the bottom of the worktable 1, preventing the placement plate 21 from continuing to rise and fall. This stopping position is the optimal position for the clamping plate 16 to clamp the hydraulic valve block body 18. When the baffle 41 contacts the worktable 1, the buffer pad 5 will deform and spread outwards upon impact, thus flattening itself. During flattening, the impact force is dissipated, thereby buffering the impact between the baffle 41 and the worktable 1.When the placement plate 21 moves to the optimal position, it will block the light emitted by the laser indicator 6. At this time, the stopping time can be determined by observing the distance between the placement plate 21 and the laser indicator 6, thereby reducing the direct impact between the baffle 41 and the worktable 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
