[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic cylinder guide sleeve tightening device, comprising a tooling table, support legs, a limiting mechanism, a locking mechanism, and a transmission mechanism. The support legs are fixedly connected to the four corners of the bottom of the tooling table. The transmission mechanism is fixedly connected to the right side of the top of the tooling table.

A sliding assembly is provided on the right side of the fixed plate.
[0007] In a preferred embodiment of the present invention, the sliding component includes a first sliding groove and a first sliding block. The first sliding block is fixedly connected to the left side of the limiting mechanism, the first sliding groove is formed on the right side of the fixed plate, the first sliding block is slidably connected to the first sliding groove, and a positioning component is provided inside the first sliding groove.
[0008] In a preferred embodiment of this utility model, the positioning component includes a positioning element, a positioning groove, a second groove, and a first spring. The positioning groove is formed on both sides of the inner wall of the first slide groove, the second groove is formed on both sides of the first slider, the positioning element is movably connected inside the second groove, the first spring is fixedly connected to the inner side of the positioning element, and the positioning element is movably connected to the positioning groove.
[0009] In a preferred embodiment of this invention, a movable rod is movably connected inside the first groove, and an elliptical block is movably connected to the surface of the movable rod.

[0010] As a preferred embodiment of this utility model, a button block is fixedly connected to the top of the movable rod, and an arc-shaped component is movably connected to the fixed plate.
[0011] As a preferred embodiment of this utility model, a second sliding groove is provided on the left side of the top of the fixing plate, a second slider is fixedly connected to the bottom of the arc-shaped component, the second slider is slidably connected to the second sliding groove, a second spring is fixedly connected to the left side inside the second sliding groove, and the other end of the second spring is fixedly connected to the left side of the positioning component.
[0012] As a preferred embodiment of this invention, a rolling bearing is fixedly connected to the right side of the first groove, and the right side of the lead screw surface is movably connected to the inner wall of the rolling bearing.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model, by setting a fixed plate, a first groove, a support plate, a motor, and a lead screw, enables the motor at the top of the support plate to start, causing the motor to drive the lead screw to rotate. Then, the lead screw drives the fixed plate to move through a threaded connection. Subsequently, the fixed plate drives the limiting mechanism to move automatically. This solves the problem that the limiting mechanism cannot move when tightening the guide sleeve, which requires the operator to push the limiting mechanism from the left side. This not only hinders the user's operation but also prolongs work efficiency and time. It has the advantage of fixed and movable guide sleeve.
[0015] 2. This utility model, by setting a sliding component, enables the limiting mechanism to drive the first slider to move, and then the first slider to move inside the first slide groove. The first slider and the first slide groove then cooperate to limit the movement of the limiting mechanism. Furthermore, by setting a positioning component, when the limiting mechanism drives the first slider to move inside the first slide groove, the positioning member in the second groove inside the first slider moves with the first slider. Then, the pressure on the first spring inside the second groove is released, and the released pressure drives the positioning member to move and insert into the corresponding positioning groove. Thus, the positioning member and the positioning groove cooperate to position the movement of the limiting mechanism.
[0016] 3. This utility model, by setting up a movable rod, an elliptical block, and a movable plate, allows for positioning when the limiting mechanism is removed. Rotating the movable rod causes the elliptical block inside the second groove to rotate, which in turn moves the movable plate. Finally, the first spring inside the second groove releases pressure, moving the movable plate and simultaneously causing the first spring to disengage the positioning component from the positioning groove. This rotation of the elliptical block controls the separation and positioning of the positioning component from the positioning groove. Furthermore, by setting up a button block and an arc-shaped component, when the movable rod rotates, the button block causes the movable rod to rotate, which in turn moves the arc-shaped component. The arc-shaped component then engages with the button block, preventing the movable rod from rotating when the positioning component is positioned in the positioning groove, and limiting the button block's position.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 protection scope of the present utility model.
[0022] like Figures 1 to 3 As shown, the present invention provides a hydraulic cylinder guide sleeve tightening device, including a tooling table 1, support legs 2, a limiting mechanism 3, a locking mechanism 4, and a transmission mechanism 5. The support legs 2 are fixedly connected to the four corners of the bottom of the tooling table 1. The transmission mechanism 5 is fixedly connected to the right side of the top of the tooling table 1. The locking mechanism 4 is fixedly connected to the output end of the transmission mechanism 5. A fixing plate 6 is movably connected to the left side of the top of the tooling table 1. The limiting mechanism 3 is movably connected to the right side of the fixing plate 6. A first groove 7 is provided on the top of the tooling table 1. The fixing plate 6 is slidably connected to the first groove 7. A support plate 8 is fixedly connected to the left side of the tooling table 1. A motor 9 is fixedly connected to the top of the support plate 8. A lead screw 10 is fixedly connected to the output end of the motor 9. The lead screw 10 is threadedly connected to the bottom of the fixing plate 6. A sliding assembly 11 is provided on the right side of the fixing plate 6.
[0023] refer to Figure 2 The sliding component 11 includes a first slide groove 111 and a first slider 112. The first slider 112 is fixedly connected to the left side of the limiting mechanism 3. The first slide groove 111 is opened on the right side of the fixed plate 6. The first slider 112 is slidably connected to the first slide groove 111. The positioning component 12 is provided inside the first slide groove 111.
[0024] As a technical optimization of this utility model, by setting a sliding component 11, the limiting mechanism 3 drives the first slider 112 to move, and then the first slider 112 moves inside the first slide groove 111. After that, the first slider 112 and the first slide groove 111 cooperate to limit the movement of the limiting mechanism 3.
[0025] refer to Figure 2 The positioning component 12 includes a positioning element 121, a positioning groove 122, a second groove 123, and a first spring 124. The positioning groove 122 is formed on both sides of the inner wall of the first slide groove 111, and the second groove 123 is formed on both sides of the first slider 112. The positioning element 121 is movably connected to the inside of the second groove 123, and the first spring 124 is fixedly connected to the inside of the positioning element 121. The positioning element 121 is movably connected to the positioning groove 122.
[0026] As a technical optimization of this utility model, by setting a positioning component 12, when the limiting mechanism 3 drives the first slider 112 to move inside the first slide groove 111, the positioning component 121 of the second groove 123 inside the first slider 112 moves with the first slider 112. Then, the pressure of the first spring 124 squeezed inside the second groove 123 is released, and then the pressure of the first spring 124 is released, which drives the positioning component 121 to move and insert into the corresponding positioning groove 122. Thus, the positioning component 121 and the positioning groove 122 cooperate to complete the positioning of the movement of the limiting mechanism 3.
[0027] refer to Figure 2 The first slide groove 111 is movably connected to a movable rod 13, and the surface of the movable rod 13 is movably connected to an elliptical block 14. The end of the first spring 124 away from the positioning member 121 is fixedly connected to a movable plate 15, and the surface of the elliptical block 14 is movably connected to the inner side of the movable plate 15.
[0028] As a technical optimization of this utility model, by setting up a movable rod 13, an elliptical block 14, and a movable plate 15, when the limiting mechanism 3 is removed for positioning, the movable rod 13 is rotated, causing the elliptical block 14 inside the second groove 123 to rotate. Then, the elliptical block 14 causes the movable plate 15 to move. Finally, the first spring 124 inside the second groove 123 releases pressure, causing the movable plate 15 to move. At the same time, the first spring 124 causes the positioning member 121 to disengage from the positioning groove 122, thereby controlling the disengagement and positioning of the positioning member 121 from the positioning groove 122 by the rotation of the elliptical block 14.
[0029] refer to Figure 3 A button block 16 is fixedly connected to the top of the movable rod 13, and an arc-shaped piece 17 is movably connected to the fixed plate 6.
[0030] As a technical optimization of this utility model, by setting a button block 16 and an arc-shaped component 17, when the movable rod 13 rotates, the button block 16 drives the movable rod 13 to rotate, and then the arc-shaped component 17 moves. After that, the arc-shaped component 17 locks and blocks the button block 16, thereby preventing the movable rod 13 from rotating when the positioning component 121 is positioned with the positioning groove 122, and limiting the button block 16 with the arc-shaped component 17.
[0031] refer to Figure 3 A second slide groove 18 is provided on the left side of the top of the fixed plate 6. A second slider 19 is fixedly connected to the bottom of the arc-shaped part 17. The second slider 19 is slidably connected to the second slide groove 18. A second spring 20 is fixedly connected to the left side inside the second slide groove 18. The other end of the second spring 20 is fixedly connected to the left side of the positioning part 121.
[0032] As a technical optimization of this utility model, by setting a second slide groove 18, a second slider 19 and a second spring 20, the arc-shaped member 17 is moved, causing the arc-shaped member 17 to drive the second slider 19 to move. Then, the second slider 19 moves inside the second slide groove 18. Finally, the second slider 19 drives the second spring 20 inside the second slide groove 18 to move and retract, thereby causing the arc-shaped member 17 to move and disengage the movable rod 13 from the limit. Afterwards, when the second spring 20 releases pressure and drives the second slider 19 to move, the arc-shaped member 17 returns to the limit.
[0033] refer to Figure 1 A rolling bearing 21 is fixedly connected to the right side inside the first groove 7, and the right side of the surface of the lead screw 10 is movably connected to the inner wall of the rolling bearing 21.
[0034] As a technical optimization of this utility model, by setting a rolling bearing 21, the inside of the rolling bearing 21 of the lead screw 10 rotates, thereby increasing the rotational stability and safety of the lead screw 10, and making the movement of the fixed plate 6 smoother.
[0035] The working principle and usage process of this utility model are as follows: In use, the limiting mechanism 3 drives the first slider 112 to move, and then the first slider 112 moves inside the first groove 111. Then, the positioning member 121 of the second groove 123 inside the first slider 112 moves with the first slider 112. Then, the pressure of the first spring 124 squeezed inside the second groove 123 is released. After that, the pressure of the first spring 124 is released, and the positioning member 121 moves and inserts into the corresponding positioning groove 122. Thus, the positioning member 121 and the positioning groove 122 cooperate to position the movement of the limiting mechanism 3. At the same time, the motor 9 on the top of the support plate 8 is started, and the motor 9 drives the lead screw 10 to rotate. Then, the lead screw 10 drives the fixed plate 6 to move through the threaded connection. Then, the fixed plate 6 drives the limiting mechanism 3 to move automatically, so that the guide sleeve moves at the same time when it rotates. Thus, the guide sleeve has the advantage of fixed movement.
[0036] In summary, this hydraulic cylinder guide sleeve tightening device, through the arrangement of a fixed plate 6, a first groove 7, a support plate 8, a motor 9, and a lead screw 10, enables the motor 9 at the top of the support plate 8 to start, causing the motor 9 to drive the lead screw 10 to rotate. Then, the lead screw 10 drives the fixed plate 6 to move through a threaded connection. Subsequently, the fixed plate 6 drives the limiting mechanism 3 to move automatically. This solves the problem that when the limiting mechanism cannot move during the tightening of the guide sleeve, the operator has to push it from the left side, which not only hinders the user's operation but also prolongs work efficiency and time.
