Description

Technical Field

[0001] This utility model relates to the field of torque converter disassembly tools, specifically a torque converter transfer gear disassembly device. Background Technology

[0002] Torque converters are key components in construction machinery, regulating and transmitting the torque output from the engine to improve the machine's efficiency. In equipment such as loaders, the performance of the torque converter is crucial. Disassembly of the torque converter requires the use of specialized tools to remove the internal drive gears.

[0003] Currently, the torque converter transfer gear disassembly device, as described in patent announcement number CN215968551U, includes a fixed sleeve. A threaded rod is rotatably connected to the upper surface of the fixed sleeve. A U-shaped traction plate is threadedly connected to the surface of the threaded rod. Threaded holes are opened on both sides of the U-shaped traction plate. Adjusting screws are threadedly connected to the inner walls of the threaded holes. Side pull plates are threadedly connected to the surface of the adjusting screws. Trapezoidal top blocks are fixedly connected to the opposite faces of the two side pull plates. Rotating blocks are fixedly connected to the opposite ends of the two adjusting screws. Nuts are threadedly connected to the surface of the two adjusting screws.

[0004] Regarding the aforementioned related technologies, the inventors believe that the trapezoidal top block is directly fixed to one side of the side pull plate, which means that during use, there needs to be space around the gear to be disassembled for the trapezoidal top block and the side pull plate to pass through. If the space around the gear to be disassembled is relatively small, the trapezoidal top block and the side pull plate will not be able to pass through, thus making it impossible to disassemble gears with relatively small surrounding spaces, resulting in poor applicability of the entire device. Utility Model Content

[0005] The purpose of this invention is to provide a torque converter transfer gear disassembly device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A torque converter transfer gear disassembly device, comprising:

[0008] A limiting mechanism includes a connecting beam. The connecting beam has symmetrically symmetrically arranged slots inside. Each of the two sets of slots has a sliding block that is slidably connected to the connecting beam. Each of the two sets of sliding blocks has a pull rod fixedly connected to its bottom. Each of the two sets of pull rods has a receiving opening on its lower inner side. Each of the two receiving openings has a connecting shaft fixedly connected to the pull rod. Each of the two sets of connecting shafts has a symmetrically arranged hook block rotatably connected to its outer side. Each hook block has a torsion spring fixedly connected to both sides. The end of each torsion spring furthest from the hook block is fixedly connected to the pull rod.

[0009] An adjustment mechanism is provided, comprising a rectangular slide rod detachably connected inside the connecting beam, wherein an adjustment screw is threaded through the internally threaded part of the rectangular slide rod.

[0010] As a further embodiment of this utility model: guide rods slide through the interior of both sets of sliding blocks, and both sets of guide rods are fixedly connected to the connecting beam.

[0011] As a further embodiment of this utility model: a first spring is sleeved on the outer side of each of the two sets of guide rods, and the two ends of the first spring are fixedly connected to the sliding block and the connecting beam, respectively.

[0012] As a further embodiment of this utility model: the rectangular slide rod slides through the connecting beam, the top of the rectangular slide rod is fixedly connected to a limiting block, one side of the connecting beam is slidably connected to a limiting pin, and a plurality of limiting grooves are evenly opened on one side of the outer wall of the rectangular slide rod, and the limiting pin is inserted into the interior of a set of the limiting grooves.

[0013] As a further embodiment of this utility model: a connecting block is fixedly connected to the end of the limiting pin away from the connecting beam, and a second spring is fixedly connected between the connecting block and the connecting beam.

[0014] As a further embodiment of this utility model: a rotating block is rotatably connected to the bottom of the adjusting screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] With the above-mentioned structure, the present invention, through the cooperation of the receiving port, hook blocks, connecting shaft and torsion spring, allows the two sets of hook blocks to be rotated and stored inside the receiving port when the pull rod is moved to the outside of the gear to be disassembled. This effectively reduces the space occupied by the hook blocks and allows them to pass through the relatively narrow space around the gear to be removed, thus facilitating the removal of gears with relatively narrow surrounding spaces and improving the applicability of the entire device.

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Please see Figure 1-4 A torque converter transfer gear disassembly device includes a limiting mechanism 1. The limiting mechanism 1 includes a connecting beam 101. Symmetrically arranged slots 102 are provided inside the connecting beam 101. Sliding blocks 103, slidably connected to the connecting beam 101, pass through the interior of each slot 102. The slots 102 are designed to accommodate the sliding blocks 103. Guide rods 109 slidably pass through the interior of each sliding block 103. Both guide rods 109 are fixedly connected to the connecting beam 101 and guide the sliding of the sliding blocks 103. Pull rods 104 are fixedly connected to the bottom of each sliding block 103 and pass through the outer side of the gear to be removed.

[0025] Both sets of guide rods 109 are fitted with a first spring 110 on their outer sides. The two ends of the first spring 110 are fixedly connected to the sliding block 103 and the connecting beam 101, respectively. The first spring 110 is designed to use its elasticity to push the two sets of sliding blocks 103 to move relative to each other, so that when the gear is pulled, the two sets of pull rods 104 can come into contact with the gear. The lower inner side of both sets of pull rods 104 is provided with a receiving opening 105. The inside of both sets of receiving openings 105 is provided with a connecting shaft 106 fixedly connected to the pull rod 104. The outer side of both sets of connecting shafts 106 is rotatably connected with symmetrically arranged hook blocks 107. The receiving openings 105 are designed to accommodate the connecting shafts 106 and hook blocks 107, so that the hook blocks 107 can rotate into the receiving openings 105, thereby reducing the space occupied by the hook blocks 107 and making it easier to remove the gear from the relatively narrow surrounding space.

[0026] Both sides of the hook block 107 are fixedly connected to torsion springs 108. The end of each torsion spring 108 away from the hook block 107 is fixedly connected to the pull rod 104. The torsion springs 108 are designed to use their elasticity to drive the hook block 107 to rotate, so that after passing the edge of the gear, the hook block 107 can rotate to be perpendicular to the pull rod 104, thereby hooking the gear. Adjustment mechanism 2 includes a rectangular slide rod 201 detachably connected inside the connecting beam 101. The rectangular slide rod 201 slides through the connecting beam 101. A limit block 203 is fixedly connected to the top of the rectangular slide rod 201. The limit block 203 is designed to limit the sliding of the rectangular slide rod 201.

[0027] The rectangular slide bar 201 has an internally threaded adjusting screw 202 that passes through it. The adjusting screw 202 is designed to drive the connecting beam 101, pull rod 104, and hook block 107 upwards when rotated, thereby facilitating the removal of the gear. A rotating block 208 is rotatably connected to the bottom of the adjusting screw 202. The rotating block 208 is designed to abut against the gear fixing shaft to reduce the probability of wear on the gear fixing shaft caused by the adjusting screw 202 during rotation.

[0028] A limiting pin 205 is slidably connected to one side of the connecting beam 101. Multiple limiting grooves 204 are evenly distributed on one side of the outer wall of the rectangular slide rod 201. The limiting pin 205 is inserted into a set of limiting grooves 204. The limiting pin 205 is designed to limit the rectangular slide rod 201 after being inserted into the limiting groove 204. A connecting block 206 is fixedly connected to the end of the limiting pin 205 away from the connecting beam 101. A second spring 207 is fixedly connected between the connecting block 206 and the connecting beam 101. The second spring 207 is designed to use its elasticity to move the connecting block 206 and the limiting pin 205 towards one side of the rectangular slide rod 201, thereby reducing the probability of the limiting pin 205 disengaging from the limiting groove 204.

[0029] In use, pulling the two sliding blocks 103 in opposite directions causes the two sets of pull rods 104 and the two sets of hook blocks 107 to move in opposite directions until the opposite sides of the two sets of pull rods 104 are moved to match the diameter of the gear to be removed. Then, the entire device is moved so that the two sets of pull rods 104 are placed outside the gear to be removed, and the hook block 107 is moved to the back side of the gear to be removed. Then, the torsion spring 108 returns to its original deformation, thereby driving the hook block 107 to rotate until the hook block 107 rotates to be perpendicular to the pull rod 104. Then, the connecting block 206 and the limiting pin 205 are pulled, causing the limiting pin 205 to disengage from the inside of the limiting groove 204. Then, the rectangular slide rod 201 is slid towards one side of the gear fixed shaft until the rotating block 208 slides close to the gear fixed shaft, and a set of limiting grooves 204 on the rectangular slide rod 201 moves. When the limit pin 205 is in contact with the connecting block 206, the pulling of the connecting block 206 is stopped, causing the second spring 207 to return to its original deformation. This causes the limit pin 205 and the limit pin 206 to move towards one side of the rectangular slide bar 201, so that the limit pin 205 is inserted into the corresponding limit groove 204, thereby limiting the rectangular slide bar 201. Then, the adjusting screw 202 is rotated, causing the adjusting screw 202 to move the rotating block 208 towards the gear fixing shaft. After the rotating block 208 and the hook block 107 contact the gear fixing shaft and the gear respectively, the adjusting screw 202 can drive the rectangular slide bar 201, the connecting beam 101 and the pull rod 104 to move towards the end of the gear fixing shaft closer to the rotating block 208, thereby causing the hook block 107 and the gear to move towards one side of the torsion spring 108, thereby removing the gear from the outside of the gear shaft.

[0030] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
