Description

Technical Field

[0001] The utility model relates to the field of hydraulic pump disassembly tooling, in particular to a portable disassembly tooling. Background Art

[0002] When hydraulic valves are used for a long time, they need to be regularly maintained and serviced, and disassembled for inspection and troubleshooting to ensure that they can be used normally. The hydraulic valve disassembly tool is an auxiliary equipment, which can usually clamp and fix the hydraulic valve to facilitate subsequent more stable disassembly of the hydraulic valve.

[0003] Existing hydraulic valve disassembly tooling is often fixed, or some parts of the equipment are complex and lack good portability. Since portability cannot be guaranteed, the hydraulic valve cannot be repaired in time when encountering some emergencies. When disassembling common parts of the hydraulic valve, some small parts in different positions are easy to be mixed up and lost. During the disassembly process, they are usually not well classified and placed in a centralized manner. If placed on other work surfaces, they are easily affected by dust. Dust attached to the parts will have an adverse effect on the normal use of the hydraulic valve.

[0004] Therefore, those skilled in the art provide a portable disassembly tool to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a portable disassembly tool is proposed. The device designs a clamping tool in a box body, and commonly used tools can be placed in a tool groove arranged in the box body and fixed by Velcro, thereby greatly improving the portability of the hydraulic valve disassembly tool. The internal clamping device is simple to operate and accurately positioned, and can achieve one-end rotation and three-end clamping. The device also designs a parts groove around the place where the hydraulic valve needs to be disassembled, so as to better realize the acceptance and storage of small parts after disassembly to avoid loss and confusion.

[0006] To achieve the above object, the present utility model provides the following technical solution: A portable disassembly tooling, including a top cover and a base. A fixing block is fixedly arranged in a groove at the rear side of the upper end of the base. A lead screw is rotatably arranged at the center of the front end of the fixing block. A front pressing block is threadedly sleeved on the lead screw at a position close to the front of the lead screw body. Fixing rods are fixedly arranged on both sides of the front end of the fixing block on both sides of the lead screw. The front pressing block is also slidably sleeved on the bodies of the two fixing rods. A linkage block is threadedly sleeved on the lead screw at a position close to the middle of the lead screw body. Both sides of the linkage block are slidably sleeved on the peripheries of the fixing rods. Rotating rods are rotatably arranged on both sides of the linkage block. A plurality of bearing blocks are fixedly arranged on both sides of the upper end of the base. A side pressing block is slidably arranged through between two bearing blocks on the same side among the plurality of bearing blocks. One end of the two side pressing blocks close to the lead screw is also rotatably arranged with one end of the adjacent rotating rod. A lower buckle is fixedly arranged at the center of one side of the base;

[0007] A plurality of tool slots are opened at the lower end of the top cover. Magic tapes are arranged on both sides of the lower end of the top cover close to some of the tool slots. A handle is fixedly arranged at a position close to the lower part of one side of the top cover. An upper buckle is fixedly arranged at the center of the lower part of one side of the top cover. A clamping block is fixedly arranged at the lower end of the upper buckle. A sliding block is slidably arranged through the middle of one side of the clamping block. A spring is arranged between the sliding block and the clamping block;

[0008] Through the above technical solution, when the hydraulic valve is placed on the bearing block, the lead screw can be rotated to make the front pressing block slide backward along the lead screw and generate extrusion on the front end of the hydraulic valve. At this time, the rear end of the hydraulic valve contacts the baffle on the fixing block. When the lead screw rotates, the linkage block will also slide forward together. During the sliding process, the rotating rods on both sides will be driven to rotate. Since the length of the rotating rod is fixed, the side pressing blocks on both sides will be driven to extrude the two side surfaces of the hydraulic valve. Three-sided fixation can be achieved by one rotation. The part slots designed at the front and rear can hold the parts on both sides after the hydraulic valve is disassembled, avoiding confusion and loss. More accurate positioning can be achieved through the fixing block, so that the hydraulic valve can be better clamped for subsequent disassembly work. The device is designed by placing the fixture in a box and placing other tools such as wrenches in the tool slots. The top cover and the base can be closed and opened through the upper buckle and the lower buckle, which is convenient for carrying and using.

[0009] Further, the upper end of the bearing block is used to place the hydraulic valve to be disassembled. The plane height of the fixing block close to the bearing block is the same as the height of the bearing block. A baffle is arranged at the upper end of the fixing block. Part slots are opened at the upper ends of the front pressing block and the fixing block;

[0010] Through the above technical solution, the hydraulic valve can find a better placement position, keeping the solenoid valve areas on both sides of the hydraulic valve above the part slots, which is convenient for temporarily classifying and receiving the scattered parts after the parts are clamped subsequently.

[0011] Further, a groove is provided at the upper end of the base near the edge, and a convex block is fixedly provided at the lower end of the top cover near the edge. The overall dimensions of the convex block fit the dimensions of the groove.

[0012] Through the above technical solution, the top cover and the base are more firmly closed after being closed.

[0013] Further, the size of the clamping block fits the size of the inner groove of the lower buckle, and a slope is provided at the lower part on one side of the sliding block.

[0014] Through the above technical solution, the upper buckle is more easily clamped and connected with the lower buckle, and remains stable and not easy to loosen after connection.

[0015] Further, the magic tape has a fluffy part and a hooked part. After the fluffy part and the hooked part are adhered, the whole magic tape remains horizontal and in a taut state.

[0016] Through the above technical solution, the tool can be placed more stably in the tool slot and is not easy to fall off.

[0017] Further, the handle is divided into two parts. The lower half is fixedly provided at the middle of one side of the base, and the upper half is fixedly provided at the middle of one side of the top cover. The two coincide after the top cover and the base are closed.

[0018] Through the above technical solution, the whole box body can be moved more stably after the two handles are joined together, and the gap generated at the joint between the top cover and the base during the overall movement can also be reduced.

[0019] Further, a rough and uneven rubber outer skin is sleeved around the non-threaded part at the front end of the lead screw.

[0020] Through the above technical solution, the lead screw is more easily rotated by the user by hand.

[0021] The utility model has the following beneficial effects:

[0022] 1. A portable disassembly tooling proposed by the utility model places common tools in a tool slot and fixes them through a magic tape, and is provided with a clamping device inside, which improves the portability of the tool. After the disassembly work of the hydraulic valve, the top cover can be screwed off to make the convex block located in the groove. The upper buckle and the lower buckle are more stably clamped and connected through the sliding block and the spring and are easy to open. After being closed, the work location can be flexibly changed by lifting the handle.

[0023] 2. A portable disassembly tooling proposed by the present utility model. The clamping device of this device is easy to operate. Just rotate one end of the lead screw to achieve three-end clamping. The fixed block is used to assist in the precise positioning of the hydraulic valve, enabling the hydraulic valve to be clamped more quickly and stably, so as to cooperate with subsequent manual use of tools or other machines to disassemble and repair the hydraulic valve. The device is provided with part slots around the place where the hydraulic valve needs to be disassembled. The parts that fall off during disassembly can be received and collected in the part slots on both sides, avoiding confusion and loss, and also avoiding contamination when placed on other working surfaces.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1-5, an embodiment provided by the present utility model: a portable disassembly tooling, including a top cover 1 and a base 6. In order to facilitate the preliminary positioning of the hydraulic valve to be clamped, a fixed block 20 is fixedly arranged in the groove at the rear side of the upper end of the base 6. The platform at the front of the upper end of the fixed block 20 is at the same height as that of a plurality of bearing blocks 12, and its height is also the same as the height of the platform at the rear end of the front pressing block 5. Fixed at one side and clamped at three ends can make the clamping position more accurate. A lead screw 4 is rotatably arranged at the center of the front end of the fixed block 20. To enable the user to better rotate the lead screw 4, a rubber outer sleeve with a rough and uneven surface is sleeved around the non-threaded part at the front end of the lead screw 4 to increase friction and make the lead screw 4 easier to rotate;

[0033] The front pressing block 5 is threadedly sleeved around the front part of the lead screw 4. Fixed rods 10 are fixedly arranged on both sides of the front end of the fixed block 20 near the lead screw 4. The front pressing block 5 is also slidably sleeved around the circumferences of the two fixed rods 10. At this time, when the lead screw 4 rotates, the front pressing block 5 will move along the two fixed rods 10 towards the front end face of the hydraulic valve. In order to achieve three-end clamping with one rotation, a linkage block 7 is threadedly sleeved around the middle part of the lead screw 4. Both sides of the linkage block 7 are slidably sleeved around the circumferences of the fixed rods 10. As the lead screw 4 rotates, the linkage block 7 will also move backward;

[0034] Rotating rods 21 are rotatably arranged on both sides of the linkage block 7. A plurality of bearing blocks 12 are fixedly arranged on both sides of the upper end of the base 6. Side pressing blocks 9 are slidably arranged through between two bearing blocks 12 on the same side among the plurality of bearing blocks 12. One ends of the two side pressing blocks 9 close to the lead screw 4 are also rotatably arranged with one ends of the adjacent rotating rods 21. When the linkage block 7 rotates backward, it will drive the rotating rods 21 to rotate, causing the side pressing blocks 9 on both sides to move towards both sides of the hydraulic valve until it is clamped. A lower buckle 8 is fixedly arranged at the center of one side of the base 6;

[0035] To increase the convenience of using this device, a plurality of tool slots 2 are opened at the lower end of the top cover 1. Wrenches and other disassembly tools can be placed in the tool slots 2. To prevent them from falling off, magic tapes 3 are arranged on both sides of the lower end of the top cover 1 near some of the tool slots 2. A handle 14 is fixedly arranged at the lower part of one side of the top cover 1. An upper buckle 15 is fixedly arranged at the center of the lower part of one side of the top cover 1. A clamping block 19 is fixedly arranged at the lower end of the upper buckle 15. A sliding block 18 is slidably arranged through the middle part of one side of the clamping block 19. A spring 17 is arranged between the sliding block 18 and the clamping block 19. When the top cover 1 is flipped downward, the convex block 13 will enter the groove 16. Then the sliding block 18 squeezes the spring 17 inward and moves to the opening on one side of the lower buckle 8. The spring 17 resets and pops out to achieve the clamping setting. At this time, the top cover 1 and the base 6 are combined, and the two handles 14 are also combined to form a box for easy carrying;

[0036] When the hydraulic valve is placed on the bearing block 12, the rotatable lead screw 4 can be rotated to make the front pressing block 5 slide forward along the lead screw 4 first, and exert extrusion on the front end of the hydraulic valve. At this time, the rear end of the hydraulic valve contacts the baffle on the fixed block 20. When the lead screw 4 rotates, the linkage block 7 will also slide forward together. During the sliding process, the two side rotating rods 21 will be driven to rotate. Since the length of the rotating rod 21 is fixed, the side pressing blocks 9 on both sides will be driven to extrude the two side faces of the hydraulic valve. Three-sided fixation can be achieved through one rotation. The part slots 11 designed at the front and rear can hold the parts on both sides after the hydraulic valve is disassembled, avoiding confusion and loss. More accurate positioning can be achieved through the fixed block 20, so that the hydraulic valve can be clamped better for subsequent disassembly work. The fixture is designed inside the box, and other tools such as wrenches are placed in the tool slot 2. The top cover 1 and the base 6 can be closed and opened through the upper buckle 15 and the lower buckle 8, which is convenient for carrying and using;

[0037] The upper end of the bearing block 12 is used to place the hydraulic valve to be disassembled. The plane height of the fixed block 20 near the bearing block 12 is the same as the height of the bearing block 12. A baffle is provided at the upper end of the fixed block 20. Part slots 11 are opened at the upper ends of the front pressing block 5 and the fixed block 20, so that the hydraulic valve can find a better placement position, keeping the solenoid valve areas on both sides of the hydraulic valve above the part slots 11, which is easy to temporarily classify and hold the scattered parts after the parts are clamped subsequently. A groove 16 is opened at the upper end of the base 6 near the edge. A convex block 13 is fixedly provided at the lower end of the top cover 1 near the edge. The overall dimensions of the convex block 13 fit the dimensions of the groove 16, making the top cover 1 and the base 6 more firmly closed after being closed;

[0038] The size of the block 19 fits the size of the inner slot of the lower buckle 8. An inclined surface is opened at the lower part of one side of the sliding block 18, making it easier for the upper buckle 15 to be snap-connected to the lower buckle 8. After connection, it remains stable and is not easy to loosen. The magic tape 3 has a fuzzy part and a hook part. After the fuzzy part and the hook part are adhered, the whole magic tape 3 remains horizontal and in a taut state, so that the tool can be placed in the tool slot 2 more stably and is not easy to fall off. The handle 14 is divided into two parts. The lower half is fixedly provided at the middle part of one side of the base 6, and the upper half is fixedly provided at the middle part of one side of the top cover 1. The two coincide after the top cover 1 and the base 6 are closed. After the two handles 14 are joined together, the whole box can be moved more stably, and the gap generated at the joint during the overall movement of the top cover 1 and the base 6 can also be reduced. The non-threaded part at the front end of the lead screw 4 is sleeved with a rough rubber outer skin, making it easier for the lead screw 4 to be rotated by the user by hand.

[0039] Working principle: When in use, the user first places the hydraulic valve on the upper end of the bearing block 12, ensuring that the lower part of the end of the hydraulic valve to be disassembled is in contact with the upper baffle of the fixed block 20, and at the same time making the part to be disassembled of the hydraulic valve located above the part slot 11. Then, the lead screw 4 is rotated. At this time, the front pressing block 5 will move towards the hydraulic valve. At the same time, the rotation of the lead screw 4 will also cause the linkage block 7 to move backward. When the linkage block 7 moves backward, it will drive the rotating rod 21 to rotate. When the rotating rod 21 rotates, the side pressing blocks 9 on both sides will move towards the hydraulic valve, achieving clamping on three sides by rotating one end. The fixed block 20 makes the positioning of the hydraulic valve more accurate. After that, the magic tape 3 can be opened, and the required tools can be taken out from the tool slot 2 to disassemble the hydraulic valve. Or the hydraulic valve can be clamped by the fixture to be more stably matched with the external machine for disassembly work. The disassembled parts can be placed in the part slot 11 for temporary storage to prevent the parts from being confused and lost. After disassembly, by turning down the top cover 1, the convex block 13 is placed in the groove 16. When the sliding block 18 contacts the lower buckle 8, it will press the spring 17 inward until the sliding block 18 is located at the opening on one side of the lower buckle 8, and the spring 17 resets to achieve the stable snap connection between the top cover 1 and the base 6. After that, the entire box body can be moved through the handle 14.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
