Description

Technical Field

[0001] This utility model relates to the field of disassembly equipment technology, and more specifically, to a hydraulic multi-functional bushing disassembly device. Background Technology

[0002] Bushings are accessories used on the outside of mechanical parts to achieve functions such as sealing and wear protection. They are rings that act as pads. In moving parts, long-term friction causes wear on the parts. When the clearance between the shaft and the hole wears to a certain extent, the parts must be replaced. Therefore, bushings are placed on the outside of the parts to protect them, which helps maintain the performance of the parts. Only the damaged bushing needs to be replaced, thus reducing the damage to the parts.

[0003] Patent application number 202421079228.X discloses a bushing removal device, including a threaded rod and multiple sets of grippers. The angle of each set of grippers can be adjusted by rotation to accommodate bushings of different sizes, thereby ensuring a tighter fit. Each set of grippers contains a motor, and a drill rod is attached to one end of each motor, allowing it to drill into the bushing. By starting the motor, the drill rod is controlled to drill a suitable distance, connecting the grippers to the bushing via the drill rod. This effectively prevents the grippers from detaching from the bushing surface during removal. Rubber pads are attached to the bottom of each set of grippers. The rubber material has a high coefficient of friction, which increases the friction between the grippers and the bushing, further ensuring the fit between the grippers and the bushing, thus making the entire removal process more stable. A rotating wheel is located above the threaded rod. By rotating the wheel, a sliding block can move on the threaded rod, thereby driving the grippers to remove the bushing from the connected parts.

[0004] Regarding the aforementioned technologies, rotating the wheel drives the threaded rod to rotate, causing the sliding block to move on the threaded rod. When one end of the threaded rod abuts against the part connected to the bushing, rotating the wheel again will cause the reaction force to disassemble the bushing from the connected part. However, for some rusted metal bushings, although the end of the threaded rod has a protective structure, it may require a large reaction force, which may not only damage the part but also reduce the disassembly efficiency of the bushing. Utility Model Content

[0005] To solve the above problems, this utility model provides a hydraulic multi-functional bushing disassembly device, which adopts the following technical solution:

[0006] A hydraulic multi-functional bushing removal device includes a hydraulic cylinder and a sleeve disposed at the end of the piston shaft of the hydraulic cylinder. A power supply component is provided on the side of the hydraulic cylinder away from the sleeve. Multiple control buttons are arranged in a linear array on the side of the power supply component away from the hydraulic cylinder. A first handle is provided on the side of the power supply component away from the hydraulic cylinder, and a second handle is provided on the side wall of the hydraulic cylinder.

[0007] The sleeve has two symmetrically distributed mounting plates on the side wall away from the hydraulic cylinder. A clamping assembly is provided between the two mounting plates. The sleeve has an installation tube on the inner wall away from the hydraulic cylinder. A cavity is opened in the installation tube. A magnetic induction coil is provided in the cavity. An installation ring is fixedly installed on the side of the installation tube away from the hydraulic cylinder. The installation ring is fixedly connected to the opposite side of the sleeve.

[0008] A second telescopic rod is fixedly installed on the inner wall of the sleeve near the hydraulic cylinder. An installation cylinder is fixedly installed at the end of the second telescopic rod. Two symmetrically distributed inlets and outlets are opened on the side wall of the installation cylinder. A clamping plate is slidably installed in each of the two inlets and outlets. A drive assembly is provided between the two clamping plates and the installation cylinder.

[0009] By adopting the above technical solution, during equipment use, the operator holds the hydraulic cylinder using the first and second handles, and then drives the hydraulic cylinder to place the sleeve onto the side wall of the bushing via the corresponding control button. The bushing is then clamped by the clamping assembly, which not only clamps the bushing but also corrects the sleeve's position, facilitating the precise movement of the mounting cylinder into the bushing via the second telescopic rod. The drive assembly then moves the clamping plates outwards from the mounting cylinder, bringing the opposite sides of the two clamping plates into contact with the inner wall of the bushing, thus fixing the bushing. The toothed grooves on the opposite sides of the two clamping plates increase the contact friction between the plates and the bushing. Finally, energizing the magnetic induction coil generates an alternating magnetic field around the bushing. The bushing and parts to be disassembled are placed in this alternating magnetic field. According to the law of electromagnetic induction, an induced electromotive force is generated inside the bushing and parts, which in turn forms an induced current, or eddy current. The current generates heat through the resistor, causing the bushing and parts to heat up rapidly. As the temperature rises, the metal material will thermally expand. Due to the tiny gap between the bushing and parts, and the difference in the coefficient of thermal expansion of different materials, the fit gap between the bushing and parts will increase during the heating process. At the same time, the rusted parts will also loosen due to the heat, greatly reducing the disassembly resistance, thus facilitating the subsequent disassembly of the bushing and improving the disassembly efficiency. Then, the mounting cylinder is moved in the reverse direction by the hydraulic cylinder, and the bushing can be removed by the restraint of two clamping plates.

[0010] Furthermore, the clamping assembly includes a first telescopic rod fixedly installed on one side of the two mounting plates, with a clamping plate fixedly installed at the end of each of the two first telescopic rods, and multiple rollers arranged in a linear array rotatably installed on one side of each of the two clamping plates.

[0011] By adopting the above technical solution, the first telescopic rod drives the clamping plate on the same side to move towards the bushing. The cooperation of the two clamping plates can clamp and stabilize the bushing, and can also correct the position of the sleeve, making it easy to accurately place the installation sleeve inside the bushing and to facilitate subsequent disassembly of the bushing. In addition, rollers are provided on the opposite side of the two clamping plates, which facilitates the movement of the clamping plates on the side wall of the bushing, thereby facilitating the stable movement of the sleeve.

[0012] Furthermore, the drive assembly includes two mounting blocks fixedly installed on the inner wall of the mounting cylinder near the hydraulic cylinder. The two mounting blocks are symmetrically distributed in the mounting cylinder. Two clamping plates slide between the two mounting blocks. Toothed plates are slidably installed on opposite sides of the two mounting blocks. The two toothed plates are rotationally symmetrically distributed in the mounting cylinder. A reduction motor is fixedly installed on the side wall of the mounting cylinder near the hydraulic cylinder. A gear is fixedly sleeved on the side wall of the output shaft of the reduction motor. Both toothed plates mesh with the gear. A first notch and a second notch are respectively opened on both sides of the two clamping plates. The opposite sides of the two toothed plates are fixedly connected to the inner wall of the first notch opened on the side wall of the clamping plate on the same side. A sliding groove is opened on the opposite side of the two mounting blocks. A slider is slidably installed in the two sliding grooves. The opposite side of the two sliders is fixedly connected to the opposite side of the toothed plate on the same side.

[0013] By adopting the above technical solution, when the mounting cylinder is located inside the bushing, the gear is driven by the reduction motor to move the gear, the gear drives the two toothed plates to move in opposite directions, and the toothed plates drive the same-side clamping plate and the same-side wall inlet and outlet to move into the bushing, so that the clamping plate contacts the inner wall of the bushing. When the toothed plates move, the toothed plates carry the same-side slider to move in the same-side slide groove. Through the cooperation of the slider and the slide groove, the toothed plates are restricted and stabilized, which helps to maintain the stability of the movement of the toothed plates and the clamping plate.

[0014] Furthermore, connecting blocks are fixedly installed on the side of the two toothed blocks away from the hydraulic cylinder, and grooves are opened on the side of the two mounting blocks away from the hydraulic cylinder. The two grooves are located on the mounting cylinder and are rotationally symmetrically distributed. Stabilizing rods are fixedly installed in the two grooves, and stabilizing blocks are slidably installed in the two grooves. Moving grooves matching the stabilizing rods on the same side are opened on the side of the two stabilizing blocks near the hydraulic cylinder. Connecting plates are fixedly installed on the side of the two connecting blocks and stabilizing blocks away from the hydraulic cylinder.

[0015] By adopting the above technical solution, when the toothed block plate moves, the toothed block plate moves synchronously with the connecting block. The connecting block moves with the stabilizing block on the same side through the connecting plate. The stabilizing block moves within the groove on the same side. Through the cooperation of the stabilizing block and the groove, the toothed block plate is restricted and stabilized, which helps to prevent the toothed block plate and the gear from disengaging and helps to maintain the transmission effect of the equipment. In addition, a stabilizing rod is provided in the groove, and the stabilizing block slides on the side wall of the stabilizing rod on the same side. The setting of the stabilizing rod helps to maintain the stability of the sliding of the stabilizing block.

[0016] Furthermore, two sets of symmetrically distributed insert rods are fixedly installed on the side of each connecting plate near the hydraulic cylinder. There are two insert rods in the same set. The connecting block and the stabilizing block have slots on the side away from the hydraulic cylinder that match the insert rods on the same side.

[0017] By adopting the above technical solution, the connecting block and the stabilizing block on the same side are fixed to the connecting plate on the same side by fasteners of existing technology. A plug is provided on one side of the connecting plate. The plug engages with the slot opened on one side of the connecting block and the stabilizing block. The engagement of the plug and the slot plays the role of positioning the connecting plate, which helps to maintain the stability of the assembly of the connecting plate, the connecting block and the stabilizing block and facilitates subsequent fixing.

[0018] Furthermore, multiple positioning rods arranged in a ring array are fixedly installed on the side of the mounting ring near the sleeve, and positioning grooves matching the positioning rods are opened on the side of the sleeve near the mounting ring.

[0019] By adopting the above technical solution, an installation ring is fixedly installed on one side of the installation tube. The installation ring and the sleeve are fixed together by fasteners of existing technology. A positioning rod is provided on one side of the installation ring. The operator places the installation tube into the sleeve, so that the positioning rod and the positioning groove opened on one side of the sleeve can be engaged, which can play the role of positioning the installation tube and the installation ring, and facilitate subsequent fixing.

[0020] In summary, this utility model has the following beneficial technical effects:

[0021] (1) In this utility model, the sleeve is moved by the hydraulic cylinder and fitted onto the side wall of the bushing. Then, the mounting cylinder and the clamping plate are moved into the bushing by the first telescopic rod. The two clamping plates are moved in opposite directions by the driving assembly, so that the two clamping plates are moved into the bushing and fit against the inner wall of the bushing, which facilitates the subsequent disassembly of the bushing. When the magnetic induction coil is energized, an alternating magnetic field is generated around the bushing. When the bushing and parts to be disassembled are placed in this alternating magnetic field, according to the law of electromagnetic induction, an induced electromotive force will be generated inside the bushing and parts, which will then form an induced current, i.e., eddy current. The current will generate heat through the resistor, causing the bushing and parts to heat up rapidly. As the temperature rises, the metal material will thermally expand. Since there is a small gap between the bushing and the parts, and the thermal expansion coefficients of different materials are different, the fit gap between the bushing and the parts will increase during the heating process. At the same time, the rusted parts will also loosen due to the heat, which greatly reduces the disassembly resistance, thus facilitating the subsequent disassembly of the bushing and improving the disassembly efficiency of the bushing.

[0022] (2) In this utility model, by setting the clamping component, the clamping plate on the same side is driven to move towards the bushing by the first telescopic rod. The cooperation of the two clamping plates plays the role of clamping and stabilizing the bushing, and can also play the role of correcting the position of the sleeve, so that the installation cylinder can be accurately placed in the bushing, and the bushing can be disassembled later.

[0037] The following is in conjunction with the appendix Figure 1-9 The present invention will be described in further detail below.

[0038] Please see Figure 1-9 A hydraulic multi-functional bushing removal device includes a hydraulic cylinder 1 and a sleeve 3 disposed at the piston shaft end of the hydraulic cylinder 1. A power supply component 2 is provided on the side of the hydraulic cylinder 1 away from the sleeve 3. Multiple control buttons are arranged in a linear array on the side of the power supply component 2 away from the hydraulic cylinder 1. A first handle is provided on the side of the power supply component 2 away from the hydraulic cylinder 1, and a second handle is provided on the side wall of the hydraulic cylinder 1. Two symmetrically distributed mounting plates 4 are provided on the side wall of the sleeve 3 away from the hydraulic cylinder 1. A clamping assembly is provided between the two mounting plates 4. The clamping assembly includes a first telescopic rod 5 fixedly installed on the opposite side of the two mounting plates 4. A clamping plate 6 is fixedly installed at the end of each of the two first telescopic rods 5. Multiple rollers arranged in a linear array are rotatably installed on the opposite side of each of the two clamping plates 6.

[0039] When using the equipment, the operator holds the hydraulic cylinder 1 by using the first and second handles. Then, the operator drives the hydraulic cylinder 1 to drive the sleeve 3 to be fitted onto the side wall of the bushing by using the corresponding control button. The first telescopic rod 5 drives the clamping plate 6 on the same side to move towards the bushing. The cooperation of the two clamping plates 6 can clamp and stabilize the bushing and can also correct the position of the sleeve 3, so that the installation cylinder 10 can be accurately placed inside the bushing, which is convenient for subsequent disassembly of the bushing. Rollers are provided on the opposite side of the two clamping plates 6, which can facilitate the movement of the clamping plates 6 on the side wall of the bushing, thereby facilitating the stable movement of the sleeve 3.

[0040] A second telescopic rod 8 is fixedly installed on the inner wall of the sleeve 3 near the hydraulic cylinder 1. An installation cylinder 10 is fixedly installed at the end of the second telescopic rod 8. Two symmetrically distributed inlets and outlets 22 are opened on the side wall of the installation cylinder 10. A clamping plate 17 is slidably installed in each of the two inlets and outlets 22. A driving assembly is provided between the two clamping plates 17 and the installation cylinder 10. The driving assembly includes two installation blocks 11 fixedly installed on the inner wall of the installation cylinder 10 near the hydraulic cylinder 1. The two installation blocks 11 are symmetrically distributed in the installation cylinder 10. The two clamping plates 17 slide between the two installation blocks 11. A toothed block plate 15 is slidably installed on the opposite side of each of the two installation blocks 11. Two toothed blocks 15 are located on the mounting cylinder 10 and are distributed in a rotationally symmetrical manner. A reduction motor 19 is fixedly installed on the side of the mounting cylinder 10 near the hydraulic cylinder 1. A gear 16 is fixedly sleeved on the side wall of the output shaft of the reduction motor 19. Both toothed blocks 15 mesh with the gear 16. A first notch and a second notch are respectively opened on both sides of the two clamping plates 17. The two toothed blocks 15 are opposite to each other and are fixedly connected to the inner wall of the first notch opened on the side wall of the clamping plate 17 on the same side. A sliding groove 20 is opened on the opposite side of the two mounting blocks 11. A slider 18 is slidably installed in the two sliding grooves 20. The opposite side of the two sliders 18 is fixedly connected to the opposite side of the toothed blocks 15 on the same side.

[0041] After the mounting cylinder 10 is inside the bushing, the gear 16 is driven to move by the reduction motor 19. The gear 16 drives the two toothed plates 15 to move in opposite directions. The toothed plates 15 drive the same-side clamping plate 17 and the same-side wall inlet / outlet 22 to move into the bushing, thereby making the clamping plate 17 contact the inner wall of the bushing. When the toothed plates 15 move, the toothed plates 15, along with the same-side slider 18, move within the same-side slide groove 20. Through the cooperation of the slider 18 and the slide groove 20, the toothed plates 15 are restricted and stabilized, which helps to maintain the stability of the movement of the toothed plates 15 and the clamping plate 17. Through the cooperation of the two clamping plates 17, the bushing is fixed.

[0042] Two toothed plates 15 are fixedly mounted with connecting blocks 14 on the side away from the hydraulic cylinder 1. Two mounting blocks 11 are provided with grooves 12 on the side away from the hydraulic cylinder 1. The two grooves 12 are located on the mounting cylinder 10 and are distributed in a rotationally symmetrical manner. Two stabilizing rods 21 are fixedly mounted in the two grooves 12. Two stabilizing blocks 23 are slidably mounted in the two grooves 12. Two stabilizing blocks 23 are provided with moving grooves that match the stabilizing rods 21 on the same side on the side closer to the hydraulic cylinder 1. Two connecting blocks 14 and stabilizing blocks 23 on the same side are fixedly mounted with connecting plates 13 on the side away from the hydraulic cylinder 1.

[0043] When the toothed plate 15 moves, the toothed plate 15 moves synchronously with the connecting block 14. The connecting block 14 moves with the stabilizing block 23 on the same side through the connecting plate 13. The stabilizing block 23 moves within the groove 12 on the same side. The cooperation between the stabilizing block 23 and the groove 12 restricts and stabilizes the toothed plate 15, which helps to prevent the toothed plate 15 and the gear 16 from disengaging and helps to maintain the transmission effect of the equipment. In addition, a stabilizing rod 21 is provided in the groove 12. The stabilizing block 23 slides on the side wall of the stabilizing rod 21 on the same side. The setting of the stabilizing rod 21 helps to maintain the stability of the sliding of the stabilizing block 23.

[0044] Two sets of symmetrically distributed insert rods are fixedly installed on the side of each connecting plate 13 near the hydraulic cylinder 1. There are two insert rods in each set. The connecting block 14 and the stabilizing block 23 have slots on the side away from the hydraulic cylinder 1 that match the insert rods on the same side. The connecting block 14 and the stabilizing block 23 on the same side are fixed to the connecting plate 13 on the same side by fasteners of the prior art. The insert rod is provided on one side of the connecting plate 13. The insert rod engages with the slots on the side of the connecting block 14 and the stabilizing block 23. The engagement of the insert rod and the slot serves to position the connecting plate 13, which helps to maintain the stability of the assembly of the connecting plate 13, the connecting block 14 and the stabilizing block 23 and facilitates subsequent fixing.

[0045] The inner wall of the sleeve 3 away from the hydraulic cylinder 1 is provided with an installation tube 24. A cavity is opened in the installation tube 24, and a magnetic induction coil 9 is installed in the cavity. An installation ring 7 is fixedly installed on the side of the installation tube 24 away from the hydraulic cylinder 1. The installation ring 7 is fixedly connected to the opposite side of the sleeve 3. When the magnetic induction coil 9 is energized, an alternating magnetic field is generated around the bushing. When the bushing and parts to be disassembled are placed in this alternating magnetic field, according to the law of electromagnetic induction, an induced electromotive force is generated inside the bushing and parts, which in turn forms an induced current, i.e., eddy current. The current generates heat through the resistance, causing the bushing and parts to heat up rapidly. As the temperature rises, the metal material will thermally expand. Due to the small gap between the bushing and the parts, and the difference in the coefficient of thermal expansion of different materials, the fit gap between the bushing and the parts will increase during the heating process. At the same time, the rusted parts will also loosen due to the heat, which greatly reduces the disassembly resistance, thereby facilitating the subsequent disassembly of the bushing and improving the disassembly efficiency. Then, the installation cylinder 10 is moved in the reverse direction by the hydraulic cylinder 1, and the bushing can be removed by the restriction of the two clamping plates 17.

[0046] Multiple positioning rods arranged in a ring array are fixedly installed on the side of the mounting ring 7 near the sleeve 3. The side of the sleeve 3 near the mounting ring 7 has a positioning groove that matches the positioning rod. The mounting ring 7 is fixedly installed on one side of the mounting tube 24. The mounting ring 7 and the sleeve 3 are fixed together by fasteners of existing technology. The mounting ring 7 has a positioning rod on one side. When the operator places the mounting tube 24 into the sleeve 3, the positioning rod and the positioning groove on one side of the sleeve 3 will engage, which can position the mounting tube 24 and the mounting ring 7, making it easier to fix later.

[0047] The implementation principle of this utility model embodiment is as follows: When using the equipment, the operator holds the hydraulic cylinder 1 by cooperating with the first and second handles, and then drives the hydraulic cylinder 1 to drive the sleeve 3 to be fitted onto the side wall of the bushing through the corresponding control button. Then, the bushing is clamped by the clamping assembly, which not only clamps the bushing, but also corrects the position of the sleeve 3, making it easier to move the mounting cylinder 10 accurately into the bushing through the second telescopic rod 8. Then, the driving assembly drives the clamping plate 17 to move outward of the mounting cylinder 10, so that the opposite sides of the two clamping plates 17 contact the inner wall of the bushing, thus fixing the bushing. The toothed grooves on the opposite sides of the two clamping plates 17 help increase the contact friction between the clamping plates 17 and the bushing. Then, the magnetic induction coil 9 is energized, which generates an alternating magnetic field around the bushing, causing the bushing to be disassembled and the zero-element... When a component is placed in this alternating magnetic field, according to the law of electromagnetic induction, an induced electromotive force will be generated inside the bushing and the component, which will then form an induced current, i.e., eddy current. The current will generate heat through the resistor, causing the bushing and the component to heat up rapidly. As the temperature rises, the metal material will thermally expand. Due to the small gap between the bushing and the component, and the difference in the coefficient of thermal expansion of different materials, the fit gap between the bushing and the component will increase during the heating process. At the same time, the rusted parts will also loosen due to the heat, which will greatly reduce the disassembly resistance, thereby facilitating the subsequent disassembly of the bushing and improving the disassembly efficiency of the bushing. Then, the hydraulic cylinder 1 drives the mounting cylinder 10 to move in the reverse direction. By restricting the two clamping plates 17, the bushing can be removed. All components in this application are connected by linear or telecommunications. The wiring connection is not in the prior art and has not been described in detail in this application.

[0048] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
