Description

Technical Field

[0001] This invention relates to the field of hydraulic cylinder installation tooling technology, and specifically to a hydraulic cylinder positioning mechanism that is easy to disassemble. Background Technology

[0002] The installation of hydraulic cylinders typically involves mounting the equipment on an installation platform. This requires positioning the hydraulic cylinder within the equipment according to the workstation parameters before securing it. Most existing installation and positioning equipment uses robotic arms to hoist and position the hydraulic cylinders. This necessitates complex parameter settings for the robotic arm during positioning, and removing the robotic arm from the hydraulic cylinder after positioning and installation also requires complex procedures. This makes the positioning and installation process complicated and redundant. Therefore, it is necessary to design appropriate tooling to achieve proper positioning of the hydraulic cylinder while ensuring ease of operation. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a hydraulic cylinder positioning mechanism that is easy to disassemble. This mechanism uses a controllable clamping bearing structure to hold the hydraulic cylinder, while other functions such as workstation positioning and lifting adjustment are set independently of the clamping structure. This allows the tooling to be disassembled simply by releasing the clamping bearing after the positioning hydraulic cylinder is installed. Furthermore, the control and adjustment structure adopts a simple rotary adjustment structure, which is convenient to operate.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions:

[0005] It includes a mounting bracket, and it also includes:

[0006] A support and guide mechanism, wherein there are several support and guide mechanisms, and the support and guide mechanisms are respectively installed on the walls of the four sides of the mounting frame;

[0007] The support foot is mounted inside the support guide mechanism;

[0008] A clamping mechanism, wherein there are several clamping mechanisms, and the clamping mechanisms are mounted inside the mounting frame;

[0009] The clamping and holding mechanism is provided with the clamping and holding bearing.

[0010] In use, the mounting frame is erected above the workstation using the support feet, and the support guide mechanism provides limiting support between the support feet and the mounting frame. The clamping mechanism controls the clamping of the bearing, thereby clamping and fixing the hydraulic cylinder. Then, the support guide mechanism controls the movement of the mounting frame, thereby controlling the movement of the clamped hydraulic cylinder for positioning. After the work is completed, the clamping bearing is released and the device is removed, thus completing the disassembly of the device.

[0011] Preferably, the support and guiding mechanism comprises:

[0012] The guide frame is fixedly mounted on the side wall of the mounting frame, and the support legs are movably mounted inside the guide frame.

[0013] The drive shaft is spun onto the guide frame via bearings, and the adjacent ends of adjacent drive shafts are driven by a bevel gear set.

[0014] A spur gear, wherein the spur gear is sleeved and fixed on the drive shaft;

[0015] A rack and pinion, wherein the rack and pinion are fixedly mounted on the side wall of the support foot, and a spur gear meshes with the rack and pinion;

[0016] A driving component, wherein the driving component is mounted on a mounting bracket and is configured to cooperate with a drive shaft;

[0017] In use, the drive shaft is rotated by the drive component, which in turn drives the spur gear to rotate. The spur gear drives the support foot to slide in the guide frame through the meshing spur rack. Thus, when the support foot is supported on the work surface, the drive shaft is rotated by the drive component, which realizes the lifting and moving of the mounting frame. This enables the clamping of the hydraulic cylinder by holding the bearing and driving the hydraulic cylinder to lift and move.

[0018] Preferably, the driving component comprises:

[0019] A one-way ratchet assembly, wherein the one-way ratchet assembly is sleeved on one of the drive shafts;

[0020] The worm gear is sleeved on a one-way ratchet assembly;

[0021] The worm gear is screwed onto the mounting bracket via bearings and is meshed with a worm wheel.

[0022] The handle is fixedly mounted on the end of the worm gear;

[0023] During use, the worm gear and worm have a self-locking characteristic. When the worm has no active driving force, it locks the worm gear, supporting the foot on the work surface. When the mounting frame moves up or down, the foot slides within the guide frame, causing the spur gear to slide on the rack and drive the drive shaft to rotate. When the mounting frame descends, the drive shaft is considered to rotate in the forward direction; when it rises, it is considered to rotate in the reverse direction. After the mounting frame is installed, it tends to descend due to gravity, which in turn causes the drive shaft to tend to rotate in the forward direction. This causes the one-way ratchet assembly to engage. This causes the worm gear to tend to rotate in the forward direction. The worm gear locks the worm gear, preventing it from rotating, which in turn prevents the drive shaft from rotating and supports the mounting bracket to prevent it from descending. When controlling the mounting bracket to rise, the bracket is lifted directly upwards. At this time, the drive shaft rotates in the reverse direction, meaning the one-way ratchet assembly is released, preventing the worm gear from rotating with the drive shaft. When controlling the mounting bracket to descend, the worm gear is rotated forward by the handle, causing the worm gear to rotate in the forward direction. The mounting bracket then descends under gravity, causing the drive shaft to rotate in the forward direction. Therefore, by controlling the number of forward rotations of the worm gear, the number of forward rotations of the drive shaft can be controlled, thus controlling the descent height of the mounting bracket.

[0024] Preferably, the clamping mechanism comprises:

[0025] The lifting and adjusting mechanism is provided in pairs on the mounting frame.

[0026] The support rod is mounted on the lifting and adjusting mechanism, and the clamping bearing is hinged to the movable end of the support rod via a universal joint;

[0027] A threaded rod, wherein the threaded rod is screwed onto a support rod via a rotating shaft;

[0028] A threaded sleeve is provided between two support rods in a set, and the end of the threaded rod is inserted into the threaded sleeve by a threaded connection.

[0029] In use, the threaded sleeve prevents the threaded rod from rotating with it due to the limit of the support rod. The threaded sleeve then pulls the threaded rod to move, and the two ends of the threaded rod move in opposite directions. This, in turn, pulls the support rod to rotate, thus opening and closing the support rod. The support rod then drives the clamping bearing to open and close, thereby clamping the hydraulic cylinder when the clamping bearing closes. When the clamping bearing is pressed against the side wall of the hydraulic cylinder, the clamping bearing rotates adaptively through the universal joint.

[0030] Preferably, the lifting adjustment mechanism comprises:

[0031] The support base is fixedly mounted on the inner wall of the mounting frame;

[0032] The lifting seat is mounted on a support seat, and the support rod is spun onto the side wall of the lifting seat via a rotating shaft;

[0033] The lead screw is screwed onto the lifting seat via a bearing, and the lead screw is threaded onto the support seat.

[0034] In use, the lead screw is rotated, which in turn moves up and down on the support base. This causes the lead screw to move up and down the lifting base, which in turn moves the support rod up and down, thereby causing the clamping bearings to move up and down. This allows for the adjustment of the up and down positions of the two clamping bearings in a set.

[0035] Preferably, the threads inside the threaded sleeve are arranged in opposite directions from the middle to both sides, and the threads on the two threaded rods inserted into the same threaded sleeve are arranged in opposite directions.

[0036] Preferably, the lower end of the support foot is fixed with a counterweight pad by bolts.

[0037] Compared with the prior art, the beneficial effects of the present invention are:

[0038] 1. This device clamps the hydraulic cylinder with a clamping bearing and supports the mounting frame with a support foot. The hydraulic cylinder is positioned by adjusting the height of the mounting frame. When disassembling this device, the clamping bearing is released to remove the device from the hydraulic cylinder.

[0039] 2. This device sets up a lifting seat on the support base of the press-up arm, and controls the movement of the lifting seat through a screw. A clamping bearing is set on the lifting seat through a support rod. By adjusting the position of the lifting seat, the position of the clamping bearing can be adjusted, thereby limiting the position of the hydraulic cylinder when clamping it.

[0057] Spur rack 2-4, the spur rack 2-4 is fixedly mounted on the side wall of the support foot 3, and the spur gear 2-3 is meshed with the spur rack 2-4;

[0058] The driving component 6 is mounted on the mounting bracket 1 and is configured to cooperate with the driving shaft 2-2.

[0059] Drive component 6 includes:

[0060] One-way ratchet assembly 6-1, wherein the one-way ratchet assembly 6-1 is sleeved on one of the drive shafts 2-2;

[0061] Worm gear 6-2, wherein the worm gear 6-2 is sleeved on one-way ratchet sleeve 6-1;

[0062] Worm 6-3, wherein the worm 6-3 is screwed onto the mounting bracket 1 via a bearing, and the worm 6-3 is meshed with the worm wheel 6-2;

[0063] Handle 6-4, wherein the handle 6-4 is fixedly mounted on the end of the worm 6-3;

[0064] Clamping mechanism 4, there are several clamping mechanisms 4, and the clamping mechanisms 4 are mounted in the mounting frame 1;

[0065] Clamping mechanism 4 includes:

[0066] The lifting adjustment mechanism 7 is arranged in groups of two on the mounting frame 1.

[0067] Support rod 4-1, wherein the support rod 4-1 is mounted on the lifting and adjusting mechanism 7;

[0068] The clamping bearing 5 is screwed onto the lower end of the support rod 4-1 via a universal joint;

[0069] Threaded rod 4-2, wherein the threaded rod 4-2 is screwed onto the support rod 4-1 via a rotating shaft;

[0070] Threaded sleeve 4-3, wherein the threaded sleeve 4-3 is disposed between two support rods 4-1 in a set, and the end of the threaded rod 4-2 is inserted into the threaded sleeve 4-3 by threaded connection;

[0071] The threads inside the threaded sleeve 4-3 are arranged with opposite threads on both sides from the center line of the threaded sleeve 4-3. Therefore, when the threaded sleeve 4-3 is rotated, the two threaded rods 4-2 inserted at both ends of the threaded sleeve 4-3 move in opposite directions.

[0072] The lifting and adjusting mechanism 7 includes:

[0073] Support base 7-1, wherein the support base 7-1 is fixedly installed on the inner wall of the mounting frame 1;

[0074] The lifting seat 7-2 is mounted on the support seat 7-1, and the support rod 4-1 is spun onto the side wall of the lifting seat 7-2 via a rotating shaft;

[0075] The lead screw 7-3 is screwed onto the lifting seat 7-2 via a bearing, and is threaded onto the support seat 7-1.

[0076] By adopting the technical solution disclosed in this invention, the following can be achieved:

[0077] When using this device, first push the support leg 3 downward with the mounting frame 1 as a reference. At this time, the guide frame 2-1 moves to the upper end of the support leg 3 and is then erected. Then, the mounting frame 1 is erected on the work surface through the support leg 3.

[0078] Rotate the lead screw 7-3, and then the lead screw 7-3 moves on the support seat 7-1. In turn, the lead screw 7-3 drives the lifting seat 7-2 to move, so as to adjust the height position of the lifting seat 7-2 with the mounting frame 1 as a reference. Then, the lifting seat 7-2 drives the clamping tile 5 to move and adjust the height position through the support rod 4-1.

[0079] Place the hydraulic cylinder to be positioned between the front and rear clamping bearings 5, then rotate the threaded sleeve 4-3. The threaded sleeve 4-3 pulls the threaded rods 4-2 on both sides closer together, and then the threaded rods 4-2 pull the support rod 4-1 to rotate. The support rods 4-1 on both sides drive the clamping bearings 5 ​​on both sides to clamp tightly, and then clamp the hydraulic cylinder by clamping the hydraulic cylinder. The clamping bearings 5 ​​are close to the outer wall of the hydraulic cylinder. At this time, the clamping bearings 5 ​​adjust their angle by adaptive rotation through the universal joint.

[0080] When the mounting bracket 1 is supported by the support foot 3, the mounting bracket 1 drives the drive shaft 2-2 to tend to descend. At this time, the spur gear 2-3 tends to descend on the spur rack 2-4, and the drive shaft 2-2 tends to rotate. At this time, the one-way ratchet sleeve 6-1 is in a positive locking state, and the worm gear 6-2 tends to rotate. Thus, the self-locking characteristics of the worm gear 6-2 and worm 6-3 prevent the worm gear 6-2 from rotating, that is, prevent the drive shaft 2-2 from rotating and prevent the support foot 3 from moving inside the guide frame 2-1. In other words, the support foot 3 supports the mounting bracket 1 and prevents the mounting bracket 1 from moving downward.

[0081] Rotating the threaded rod 4-2 by the handle 6-4 causes the threaded rod 4-2 to drive the worm gear 6-2 to rotate, which in turn causes the one-way ratchet sleeve 6-1, which is locked in the positive direction, to rotate the worm gear 6-2 a corresponding number of turns, thereby causing the drive shaft 2-2 to rotate. At this time, the mounting bracket 1 moves downward under gravity, thereby driving the hydraulic cylinder to be lowered.

[0082] When removing this device from the hydraulic cylinder, simply open the clamping bearing 5 and remove the mounting bracket 1.

[0083] The technical advantages achieved by adopting the above technical solution are as follows:

[0084] 1. This device clamps the hydraulic cylinder by clamping the bearing 5 and supports the mounting frame 1 by supporting the support foot 3. The hydraulic cylinder is positioned by adjusting the height of the mounting frame 1. When disassembling this device, the clamping bearing 5 is released to remove the device from the hydraulic cylinder.

[0085] 2. In this device, a lifting seat 7-2 is set on the support seat 7-1 and the movement of the lifting seat 7-2 is controlled by the lead screw 7-3. The clamping bearing 5 is set on the lifting seat 7-2 by the support rod 4-1. By adjusting the position of the lifting seat 7-2, the position of the clamping bearing 5 can be adjusted, so as to limit the position of the hydraulic cylinder when clamping the hydraulic cylinder.

[0086] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
