Technical Field
[0001] This invention relates to the field of bushing removal tools, and more particularly to a bushing removal tool. Background Technology
[0002] Automotive bushings have a good cushioning effect and are crucial to the stability of a car. After a long period of use, the bushings may age or even crack, reducing their cushioning effect and seriously affecting the driving quality of the car.
[0003] When it is necessary to replace the bushing during maintenance, the automotive parts that have the bushing installed have various shapes and require different clamps to fix them. After fixing, it is also necessary to align the cylinder with the bushing and the extrusion tool. The operation is cumbersome and the replacement efficiency is low, which urgently needs to be improved. Summary of the Invention
[0004] To address the technical problems existing in the background art, the present invention proposes a bushing disassembly tool.
[0005] The present invention provides a bushing removal tool, comprising a support and a pressing component, a bearing component, and a driving component mounted on the support; there is a receiving space for placing a bushing between the pressing component and the bearing component;
[0006] The drive component is connected to the extruder and is used to drive the extruder closer to or away from the carrier.
[0007] Preferably, the carrier specifically includes a base, a plurality of sleeves of the same type that are nested together, and a pin, wherein one sleeve is fitted on the base so that the plurality of sleeves and the base can move relative to each other in the axial direction of the sleeve.
[0008] The carrier also has slots that pass through multiple sleeves and extend to the base, with pins inserted into the slots to fix the multiple sleeves and the base.
[0009] Preferably, the pin has a support portion and a load-bearing portion arranged in the same plane and at different heights, and a connecting portion connecting the two. The top surface of the connecting portion is an inclined sliding surface, and both the sliding surface and the load-bearing portion have an extension dimension suitable for the thickness of the sleeve in the axial direction of the pin.
[0010] Preferably, the portion of the slot located on the pedestal has space adapted to accommodate the connecting portion and the supporting portion.
[0011] Preferably, the base specifically includes a column portion and a plate portion connected to the bottom of the column portion. When the pin is inserted into the slot to fix the multiple sleeves and the base, the bottom ends of the multiple sleeves abut against the plate portion.
[0012] Preferably, it also includes a pin and at least one slider, the extruder is cylindrical, and the extruder has a screw hole arranged coaxially therewith and a pin hole arranged radially along the extruder and communicating with the screw hole;
[0013] The pin is threaded into the threaded hole and has a pointed tip. The slider is slidably installed in the pin hole and has a curved surface that fits the tip of the pin. The tip of the pin abuts against the curved surface of the slider. When the pin moves down, the slider extends out of the pin hole.
[0014] Preferably, it also includes an adjusting rod, and the outer wall of the extruder has a special-shaped opening with a connecting screw hole, and a plurality of insertion holes are evenly arranged on the pin shaft, and one end of the adjusting rod is detachably installed in the insertion hole through the special-shaped opening.

[0023] Figure 5 This is a schematic diagram illustrating the interaction between a bushing removal tool and a bushing according to the present invention. Detailed Implementation
[0024] like Figure 1 As shown, Figure 1This is a schematic diagram of one embodiment of a bushing removal tool proposed in this invention.
[0025] Reference Figure 1 The present invention proposes a bushing removal tool, including a support 1 and a pressing member 2, a bearing member 3 and a driving member 4 installed on the support 1; there is a receiving space for placing the bushing between the pressing member 2 and the bearing member 3.
[0026] The drive component 4 is connected to the extruder 2 and is used to drive the extruder 2 to move closer to or away from the carrier 3.
[0027] The driving component 4 is a screw rod that is threaded onto the support 1.
[0028] Reference Figure 5 In practical use, the present invention involves placing the cylinder with the bushing installed in the receiving space, rotating the screw, which drives the extrusion member 2 to approach the support member 3 and press the bushing into the receiving space. Continuing to rotate the screw, the bushing can be separated from the automotive part, thus completing the disassembly. During this process, it is not necessary to fix the automotive part; simply placing the cylinder with the bushing installed on the automotive part in the receiving space and driving the extrusion member 2 to press the bushing through the drive member 4 can detach the bushing from the automotive part, greatly simplifying the disassembly process and effectively improving disassembly efficiency.
[0029] In the above embodiments, since the bushing needs to move relative to the component when it is removed from the automotive component, it is necessary to open a circular hole on the carrier 3 to accommodate the bushing. However, such a circular hole is only used for the removal of bushings of one size. To solve this problem, the following further embodiments are proposed.
[0030] Reference Figure 2 In a further embodiment, the support member 3 specifically includes a base 31, a plurality of sleeves 32 of the same type and sleeved together, and a pin 33, wherein one sleeve 32 is sleeved on the base 31 so that the plurality of sleeves 32 and the base 31 can move relative to each other in the axial direction of the sleeve 32.
[0031] The carrier 3 also has a slot 34 that passes through multiple sleeves 32 and extends to the base 31. The pin 33 is inserted into the slot 34 to fix the multiple sleeves 32 and the base 31.
[0032] It should be noted that the pin 33 has a scale corresponding to the number of sleeves 32 to determine the insertion depth of the pin 33. The thickness of the sleeve 32 is set to match the size of the cylinder body for installing the bushing, or the size of the sleeve 32 is reasonably set according to the size of the cylinder body of different bushing sizes.
[0033] In the specific implementation of this embodiment, the insertion depth of the pin 33 is first determined according to the size of the bushing body, so that the sleeve 32 and the base 31 that are sealed with the bushing can move along its axial direction together with the bushing, so that the size of the round hole that accommodates the bushing is controllable, which can be applied to the disassembly of bushings of different sizes, further improving the practicality of the tool.
[0034] In the above further embodiments, when the extrusion member 2 and the bearing member 3 have not fully extruded the bushing, the bushing is prone to slippage and requires manual support. To solve this problem, the following further embodiments are proposed.
[0035] Reference Figure 2 In a further embodiment, the pin 33 has a support portion 331 and a bearing portion 333 arranged in the same plane and of different heights, and a connecting portion 332 connecting the two. The top surface of the connecting portion 332 is an inclined sliding surface 3321, and in the axial direction of the pin 33, both the sliding surface 3321 and the bearing portion 333 have an extension dimension adapted to the thickness of the sleeve 32.
[0036] In the specific implementation of this embodiment, the insertion depth of the pin 33 is first determined according to the size of the bushing cylinder, so that the sliding surface 3321 is on the sleeve 32 that contacts the cylinder on which the bushing is installed. The cylinder is pressed, and at this time the cylinder squeezes the sleeve 32 that contacts it, so that it slides relative to the sliding surface 3321 and enters the bearing part 33, while being staggered vertically from the other sleeves 32. The other sleeves 32 form a clamp on the cylinder to prevent the bushing from sliding before the extrusion member 2 and the bearing member 3 have fully squeezed the bushing. The bushing is then squeezed again by the extrusion member 2 to disassemble it, which can avoid the safety hazards caused by manual support and further improve the safety of the tool.
[0037] It should be noted that the portion of the slot 34 located on the base 31 has space to accommodate the connecting portion 332 and the supporting portion 333.
[0038] Reference Figure 2 In the specific structural design, the base 31 specifically includes a column part 311 and a flat plate part 312 connected to the bottom of the column part 311. When the pin 33 is inserted into the slot 34 to fix the multiple sleeves 32 and the base 31, the bottom ends of the multiple sleeves 32 abut against the flat plate part 312.
[0039] When the bushing is removed, the flat plate 312 can be pushed upward to simultaneously reset multiple sleeves 32 and column parts 311, and at the same time, the bushings located in the multiple sleeves 32 can be further unloaded.
[0040] In the above embodiment, since the size of the extruder 2 is smaller than the size of the bushing, when the bushing cracks, during the extrusion process, when the bushing detaches from the cylinder of the automotive part, some of the bushing rubber will adhere to the inner wall of the cylinder. To solve the above problem, another embodiment is proposed.
[0041] Reference Figure 3 In another embodiment, it also includes a pin 5 and at least one slider 6. The extruder 2 is cylindrical and has a screw hole 21 arranged coaxially therewith and a pin hole 22 arranged radially along the extruder 2 and communicating with the screw hole 21.
[0042] The pin 5 is threaded into the screw hole 21. The pin 5 has a tip. The slider 6 is slidably installed in the pin hole 22. The slider 6 has a curved surface that adapts to the tip of the pin 5, and the tip of the pin 5 abuts against the curved surface of the slider 6. When the pin 5 moves down, the slider 6 extends out of the pin hole 22.
[0043] It should be noted that multiple pin holes 22 can be set, the multiple pin holes 22 can be set to be coplanar, and the slider 6 can be installed in the multiple pin holes 22 respectively.
[0044] In actual use, the slider 6 is slid outward, and the pin 5 is rotated from the bottom of the screw hole 21 using a tool to move it downward. At this time, the slider 6 cannot be fully reset and is exposed outside the pin hole 22. The extension size of the slider 6 is adjusted according to the size of the bushing. When the extruder 2 presses out the bushing, the slider 6 can scrape off the rubber attached to the inner wall of the cylinder to reduce the amount of rubber attached to the inner wall of the cylinder and improve the practical performance of the tool.
[0045] Reference Figure 4 Furthermore, it also includes an adjusting rod 7, and the outer wall of the extruder 2 has a special-shaped opening 23 with a connecting screw hole 21. Multiple insertion holes 51 are evenly arranged on the pin 5. One end of the adjusting rod 7 is detachably installed in the insertion hole 51 through the special-shaped opening 23.
[0046] It should be noted that the extension direction of the irregular opening 23 is adapted to the travel path of the socket 51, and the irregular opening 23 can accommodate at least two sockets 51 at the same time.
[0047] In practical use, the pin can be connected to the irregular opening 23 through the insertion hole 51 via the adjusting rod 7, thereby rotating the pin 5 to adjust its position. The operation is simple and can improve the adjustment efficiency of the pin 5.
[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
