Description

Technical Field

[0001] This utility model relates to the field of mechanical maintenance, and in particular to a quick-release hydraulic puller device. Background Technology

[0002] In mechanical maintenance, rotating parts such as bearings and gears that need to be replaced or maintained regularly often require hub disassembly. Traditional disassembly processes mainly use hammering and bolt puller techniques: hammering uses impact force to cause displacement of mating parts, while bolt puller uses helical mechanical force to achieve smooth disassembly.

[0003] Traditional disassembly methods typically employ mechanical external forces such as hammering or bolt pulling. While these methods are simple to operate, they have limitations such as difficulty in controlling the impact force and potential damage to mating surfaces, affecting the subsequent use of the parts. Furthermore, during the disassembly of gears, the gears vary in height, requiring manual lifting of the tools for disassembly. Prolonged lifting causes arm pain, making disassembly extremely inconvenient. Utility Model Content

[0017] 2. In this utility model, the rotation of the drive motor rotates the bidirectional screw, thereby moving the traction sliders on both sides simultaneously, thus flipping the flip plate and raising the height of the lifting plate, thereby adjusting the disassembly height.

[0024] 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 protection scope of the present utility model.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a quick-release hydraulic puller device, characterized in that it includes: a movable support plate 1 for movable support, an upper lifting plate 2 attached to the top of the movable support plate 1, a hydraulic seat 7 fixedly connected to the top of the upper lifting plate 2, a hydraulic push rod 5 fixedly connected to the output end of the hydraulic seat 7, a traction plate 16 fixedly connected to the outside of the hydraulic push rod 5, multiple supporting plates 9 rotating around the outside of the traction plate 16, a mounting frame 8 fixedly connected to the front end of the hydraulic seat 7, fixing posts 19 fixedly connected to both sides of the groove inside the mounting frame 8, and limiting grooves 18 opened on both sides of the supporting plates 9, with the outside of the fixing posts 19 respectively corresponding to the limiting grooves. Inside the groove 18, a self-adjusting outward pull assembly is installed on the outside of the support plate 9 to facilitate the disassembly of wheel parts. The self-adjusting outward pull assembly includes a rotating column 12 that rotates inside the groove at the front end of the support plate 9. A bonding plate 14 is fixedly connected to the inside of the rotating column 12, and an outward pull plate 15 is fixed to the outside of the bonding plate 14. The two sides of the rotating column 12 are connected to the inside of the groove of the support plate 9 through torsion springs 11. A limiting rod 13 is fixedly connected to the outside of the bonding plate 14 inside the groove of the support plate 9 to limit the outward flipping of the bonding plate 14. A limiting pull rod 17 is fixedly connected to the front end of the hydraulic push rod 5, and the outside of the limiting pull rod 17 is slidably connected to the middle of the mounting frame 8.

[0026] The working principle of the clamping device is as follows: First, the wheel-like parts are positioned in the inner area of ​​multiple clamping plates 9. Then, the hydraulic seat 7 is activated to drive the hydraulic push rod 5 to generate an inward pulling force. This pulling force is converted into a rearward pulling force through the traction plate 16. During the movement of the traction plate 16, the fixed column 19 slides along the limiting slide groove 18, causing the clamping angle of the clamping plate 9 to gradually decrease. When the contact plate 14 contacts the outer side of the wheel-like parts, it can automatically adjust the flip angle according to the contour of the wheel-like parts to achieve adaptive clamping. At the same time, the outer deflector plate 15 closely contacts the other side of the wheel-like parts. Under the continuous pulling force of the hydraulic push rod 5, not only is the clamping stability enhanced, but the disassembly function of the wheel-like parts is also realized simultaneously. Throughout the process, the limiting pull rod 17 slides precisely within the mounting frame 8, which not only ensures the stability of the device operation, but also effectively protects the integrity of the wheel-like parts, significantly improving the convenience and safety of the disassembly operation.

[0027] Reference Figure 1 and Figure 4 A bidirectional screw 10 is used to rotate the inner middle of the movable support plate 1. The two sides of the movable support plate 1 are connected to the bottom end of the lifting plate 2 through an upward linkage assembly to facilitate the disassembly of wheel parts of different heights. The upward linkage assembly includes traction sliders 20 that slide on both sides of the movable support plate 1. A flip plate 4 is rotatably connected to the outside of each traction slider 20. The inside of the flip plate 4 is rotatably connected to the bottom two sides of the lifting plate 2. The inside of the traction slider 20 is threadedly connected to the outside two sides of the bidirectional screw 10. A drive motor 3 is fixedly connected to the left side of the inside of the movable support plate 1. The drive end of the drive motor 3 is fixedly connected to the left side of the bidirectional screw 10. A plurality of limit rods 6 are fixedly connected to the top of the movable support plate 1. The outside of the limit rods 6 is slidably connected to the inside of the lifting plate 2.

[0028] The working process of this wheel-type parts disassembly device is as follows: First, the lateral angle of the movable support plate 1 is adjusted manually to adapt to the position of the workpiece. Then, the drive motor 3 is started, driving the bidirectional screw 10 to rotate. Through the meshing transmission between the external thread of the screw and the internal thread of the traction slider 20, the two traction sliders 20 on both sides move synchronously towards the center. This movement drives the flipping plate 4 to flip inward through mechanical linkage, thereby applying an upward thrust to the bottom of the lifting plate 2. During this process, the limit rod 6 provides precise guidance to ensure the smooth lifting of the lifting plate 2. At the same time, the height of the clamping plate 9 is adjusted accordingly to achieve adaptive adjustment of the disassembly height. This device achieves rapid positioning and stable disassembly of wheel-type parts in different positions through mechanical linkage mechanism, significantly improving work efficiency and reducing manual operation intensity.

[0029] Working principle: When disassembling wheel parts, the movable support plate 1 is pushed to adjust its lateral angle. At this time, the drive motor 3 is started to rotate the bidirectional screw 10. The external thread of the bidirectional screw 10 contacts the inner thread of the traction slider 20, which in turn contacts the external thread of the bidirectional screw 10. This moves the traction sliders 20 on both sides inward simultaneously, generating an inward thrust on the flipping plate 4, thus flipping the plate 4. This generates an upward thrust on the bottom of the lifting plate 2, which is limited by the limiting rod 6, ensuring the stability of the lifting plate 2. The holding plate 9 is adjusted according to its height to control the disassembly height, allowing the wheel parts to be disassembled. The component is located inside multiple clamping plates 9. At this time, the hydraulic seat 7 is activated, which generates an inward pulling force on the hydraulic push rod 5, thereby generating a rearward pulling force on the traction plate 16. As the traction plate 16 moves, the fixing column 19 slides inside the limiting slide groove 18, reducing the clamping angle of the clamping plate 9. When the bonding plate 14 contacts the outer side of the wheel component, the bonding plate 14 flips because of the side of the wheel component, thereby clamping and fixing the wheel component. Meanwhile, the outer deflector plate 15 is bonded to the other side of the wheel component. Due to the pulling force generated by the hydraulic push rod 5, the wheel component is further clamped while the wheel component is disassembled. The limiting pull rod 17 slides inside the mounting frame 8, thereby limiting the movement.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
