Description

Technical Field

[0001] This utility model relates to the field of oil seal disassembly and assembly technology, and in particular to a tooling for disassembling a skeleton oil seal. Background Technology

[0002] In the field of mechanical repair and equipment maintenance, the efficiency and safety of disassembly of skeleton oil seals, as key sealing components, directly affect the progress of equipment maintenance and the integrity of components. With the diversification of industrial equipment, the specifications of skeleton oil seals are becoming increasingly diverse, and the requirements for the adaptability and ease of operation of disassembly tools are constantly increasing. Traditional disassembly tools, due to their single function and complex operation, can no longer meet the needs of efficient maintenance.

[0003] Existing tooling for disassembling skeleton oil seals has significant drawbacks: First, it lacks adaptability. Traditional tools have fixed structural dimensions, making them unsuitable for disassembling oil seals of different specifications, requiring frequent tool changes and increasing maintenance costs and time. Second, it is prone to damaging components during disassembly. Unstable fixing can easily scratch the oil seal or equipment surface during disassembly, and may even cause component deformation, affecting subsequent sealing performance. Third, the operation is cumbersome. The fixing and limiting steps are complex, requiring multiple people to coordinate calibration, which not only reduces disassembly efficiency but also easily leads to oil seal breakage due to uneven force, increasing maintenance difficulty. These problems restrict the safety and efficiency of skeleton oil seal disassembly. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a skeleton oil seal disassembly tool, which aims to solve the problems of poor adaptability, disassembly of easily damaged parts, and cumbersome operation in existing skeleton oil seal disassembly tools.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A tooling for disassembling a skeleton oil seal includes a housing. Connecting rods are fixedly connected to both ends of the top side of the housing. A handle is fixedly connected to the top side of the connecting rods at both ends. A movable groove is formed on the adjacent side of the connecting rods at both ends. A limit component is provided inside the movable groove at both ends. A cavity is formed on the bottom side of the housing. A turntable is rotatably connected to the top side of the housing. The bottom side of the turntable penetrates the top side of the housing, and movable plates are connected to both ends of the turntable through connecting components.

[0006] Furthermore, the connecting component includes a connecting strip, and a second rotating shaft is fixedly connected to the adjacent side of the connecting strip at both ends. The top side of the second rotating shaft at both ends is rotatably connected to the left and right ends of the bottom side of the turntable, respectively. A first rotating shaft is fixedly connected to the opposite side of the connecting strip at both ends, and the bottom side of the first rotating shaft at both ends is rotatably connected to the top side of the moving plate at both ends, respectively.

[0007] Furthermore, multiple inserts are fixedly connected to the bottom ends of the movable plates on the side closest to each other, and through holes are opened at both the front and rear ends inside the movable plates.

[0008] Furthermore, both the front and rear ends of the cavity are fixedly connected to sliding rods, and the outer walls of the sliding rods are slidably connected to the inside of the through hole.

[0009] Furthermore, the limiting component includes a movable sleeve, on both the left and right sides of the movable sleeve are fixedly connected to movable strips, and the opposite ends of the outer walls of the movable strips at both ends are slidably connected to the interior of the movable grooves at both ends, and a spline shaft is fixedly connected to the bottom side of the movable sleeve.

[0010] Furthermore, a spline groove is provided on the top side of the turntable, a screw is rotatably connected to the bottom side of the spline groove, and a knob is fixedly connected to the top side of the screw.

[0011] Furthermore, both the movable sleeve and the spline shaft are sleeved on the outer wall of the screw.

[0012] Furthermore, the outer wall of the spline shaft is located inside the spline groove, and the spline groove has more grooves than the teeth of the spline shaft.

[0013] This utility model has the following beneficial effects: 1. In this utility model, rotating the knob causes the spline shaft to disengage from the spline groove, releasing the limit on the turntable. Rotating the turntable drives the moving plate to move along the slide bar towards the center via the connecting strip, which can fix different sizes of skeleton oil seals. Inserting the insert into the bottom side of the oil seal enhances stability and improves the versatility of the device.

[0014] 2. In this utility model, after the insert is inserted, the knob is rotated in the opposite direction. Because the spline shaft has more spline grooves, it can be re-inserted and the turntable, moving plate and insert can be fixed. It can be disassembled by holding the handle and applying force. The operation is simple and the fixation is firm, ensuring that the disassembly process is stable and efficient. Attached Figure Description

[0017] 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.

[0018] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a skeleton oil seal disassembly fixture, comprising a housing 1, with connecting rods 3 fixedly connected to both the left and right ends of the top side of the housing 1, and gripping rods 4 fixedly connected to the top sides of the connecting rods 3 at both ends. Moving grooves 17 are formed on adjacent sides of the connecting rods 3 at both ends, and moving sleeves 2 are provided inside the moving grooves 17 at both ends. A cavity 12 is formed on the bottom side of the housing 1, and a turntable 9 is rotatably connected to the top side of the housing 1. The bottom side of the turntable 9 penetrates the top side of the housing 1, and moving plates 8 are connected to both the left and right ends of the turntable 9 via connecting strips 19. A rotating shaft 16 is fixedly connected to each side of the two ends of the rotating shaft 16. The top sides of the rotating shaft 16 at both ends are rotatably connected to the left and right ends of the bottom side of the turntable 9, respectively. A rotating shaft 15 is fixedly connected to each side of the connecting strip 19 at both ends. The bottom sides of the rotating shaft 15 at both ends are rotatably connected to the top sides of the moving plates 8 at both ends, respectively. Multiple inserts 14 are fixedly connected to the bottom ends of the moving plates 8 at both ends of the two ends of the moving plates 8. Through holes 18 are opened at both the front and rear ends of the moving plates 8. Slide rods 10 are fixedly connected to both the front and rear ends of the cavity 12. The outer wall of the slide rods 10 is slidably connected to the inside of the through holes 18.

[0019] Specifically, first, rotating knob 5 drives screw 6 to rotate, causing movable sleeve 2 and spline shaft 11 to move upwards. Spline shaft 11 disengages from spline groove 13, releasing the restriction on turntable 9. Then, the device is placed on top of the oil seal skeleton to be disassembled, allowing the top of the oil seal to enter cavity 12. Rotating turntable 9 drives two rotating shafts 16 to rotate, which in turn drives movable plate 8 to move via connecting strip 19. Because slide rod 10 passes through through hole 18, movable plate 8 will move towards the center along slide rod 10, thus fixing the oil seal skeleton and adapting to oil seals of different sizes. Simultaneously, insert 14 will be inserted into the bottom of the oil seal, enhancing disassembly stability.

[0020] Reference Figure 1 and Figure 3The movable sleeve 2 is fixedly connected to both the left and right sides with movable strips 7. The two ends of the outer walls of the movable strips 7 are slidably connected to the inside of the movable grooves 17 at both ends. The bottom side of the movable sleeve 2 is fixedly connected to a spline shaft 11. The top side of the turntable 9 is provided with a spline groove 13. The bottom side of the spline groove 13 is rotatably connected to a screw 6. The top side of the screw 6 is fixedly connected to a knob 5. The movable sleeve 2 and the spline shaft 11 are both sleeved on the outer wall of the screw 6. The outer wall of the spline shaft 11 is located inside the spline groove 13. The tooth groove of the spline groove 13 is more than the tooth of the spline shaft 11.

[0021] Specifically, after inserting the insert 14 into the bottom of the oil seal, rotate the knob 5 and screw 6 in the opposite direction to move the moving sleeve 2 and the spline shaft 11 downwards. Since the number of grooves in the spline groove 13 is greater than the number of teeth in the spline shaft 11, even if the turntable 9 has rotated, the spline shaft 11 can still be inserted into the spline groove 13, re-fixing the turntable 9, the moving plate 8, and the insert 14. Finally, apply force by gripping the handle 4 to complete the disassembly of the skeleton oil seal. The entire device is supported by the outer casing 1, ensuring stable operation.

[0022] Working principle: In use, first turn knob 5 to drive screw 6 to rotate, which in turn drives moving sleeve 2 and spline shaft 11 upward, causing spline shaft 11 to leave the inside of spline groove 13, thereby releasing the restriction of spline shaft 11 on turntable 9. Then, place the device on top of the skeleton oil seal to be disassembled, and let the top of the skeleton oil seal enter the cavity 12. Rotate turntable 9 to drive the two rotating shafts 16 to rotate, which in turn drives the two moving plates 8 to move through the two connecting strips 19. Since the sliding rod 10 is located inside the through hole 18, when turntable 9 rotates, the two moving plates 8 will move towards the center along the sliding rod 10, thereby fixing the skeleton oil seal. The device is designed to accommodate and disassemble oil seals of different sizes. When the oil seal is positioned, the insert 14 is inserted into the bottom of the oil seal. After the insert 14 is inserted into the bottom of the oil seal, the knob 5 and screw 6 are rotated in the opposite direction, causing the moving sleeve 2 to move the spline shaft 11 downward. Since the number of grooves in the spline groove 13 is greater than the number of teeth in the spline shaft 11, the spline shaft 11 can still be inserted into the spline groove 13 after the turntable 9 rotates. After the spline shaft 11 is inserted into the spline groove 13, it will fix the turntable 9 again and simultaneously fix the moving plates 8 and insert 14 at both ends. Then, by holding the handle 4 and applying force, the oil seal can be disassembled.

[0023] 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.
