Description

Technical Field

[0001] This utility model relates to the field of automotive repair technology, specifically to a disassembly tool for a transmission housing. Background Technology

[0002] A transmission housing remover, also known as an engine / transmission flipper, is a maintenance tool used to fix and flip the engine / transmission.

[0003] Existing gearbox housing removers typically only secure gearboxes for small vehicles or large vehicles (trucks). Truck gearboxes are heavy and long, requiring securing both sides, while small vehicle gearboxes only need securing one side. However, securing both types of gearboxes usually requires two different models of tilting frames or different clamps, which increases equipment costs and reduces operational efficiency due to the installation and replacement of clamps. Therefore, we propose a gearbox housing remover. Utility Model Content

[0004] The purpose of this invention is to provide a disassembly tool for a transmission housing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a disassembly device for a transmission housing, comprising a fixed arm, a folding assembly for folding deformation provided on one side of the fixed arm, the folding assembly including a hinge seat, one side of the hinge seat being fixedly connected to the bottom of one side of the fixed arm, the folding arm being hinged inside the hinge seat via a hinge, a first movable groove being provided inside the fixed arm, a first adjusting shaft being rotatably connected to the inner wall of the opposite side of the first movable groove via a bearing, a second movable groove being provided inside the folding arm, a second adjusting shaft being rotatably connected to the inner wall of the opposite side of the second movable groove via a bearing, an adjusting screw being rotatably connected inside the second adjusting shaft, an adjusting knob for rotating the adjusting screw being fixedly connected to the other end of the adjusting screw, and the adjusting screw being threadedly connected inside the first adjusting shaft.

[0006] Preferably, both the fixed arm and the folding arm have a first fixing bolt for fixing the transmission connected internally by threads.

[0007] Preferably, a fixing screw is fixedly connected to the bottom of the folding arm, an adjusting plate is sleeved on the side surface of the fixing screw, a fastening nut is abutted against the bottom of the adjusting plate, and the fastening nut is threaded onto the fixing screw. The fastening nut is rotated on the fixing screw to press against the adjusting plate, and a second fixing bolt for fixing the transmission is rotatably connected inside the adjusting plate.

[0008] Preferably, a rotating shaft is fixedly connected to one side of the fixed arm, and a rectangular shell is rotatably connected to the side surface of the rotating shaft. A worm gear is fixedly sleeved on a section of the side surface of the rotating shaft located inside the rectangular shell. A worm is drivenly connected to the bottom of the worm gear. One end of the worm extends out of one side of the rectangular shell and is rotatably connected to the rectangular shell. A rotating wheel is fixedly connected to the end of the worm extending out of the rectangular shell. A throttle handle is rotatably connected to the side of the rotating wheel away from the rectangular shell.

[0010] Preferably, the folding components are in two sets and are symmetrically distributed along the centerline of the fixed arm.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By using the folding assembly, the adjustment knob is rotated, which in turn drives the adjustment screw to rotate. This causes the folding arm to flip through the hinge with the fixed arm, so that the bottom of the folding arm faces the side opposite to the rectangular shell. This allows it to be transformed into two different configurations, enabling it to be fixed to different types of transmissions and thus improving compatibility.

[0013] The folding assembly allows for adjustable folding angles of the folding arm, enabling the securing of truck and small vehicle transmissions. This eliminates the need to purchase different models of tilting frames and replace clamps, reducing equipment costs and improving maintenance efficiency by minimizing clamp replacements.

[0021] This utility model provides a technical solution: such as Figures 1-4The disassembly tool shown includes a fixed arm 1. A folding assembly for folding deformation is provided on one side of the fixed arm 1. The folding assembly includes a hinge seat 2, one side of which is fixedly connected to the bottom side of the fixed arm 1. A folding arm 3 is hinged inside the hinge seat 2 via a hinge. A first movable groove 9 is formed inside the fixed arm 1. A first adjusting shaft 5 is rotatably connected to the inner wall of the opposite side of the first movable groove 9 via a bearing. A second movable groove 10 is formed inside the folding arm 3. A second adjusting shaft 8 is rotatably connected to the inner wall of the opposite side of the second movable groove 10 via a bearing. An adjusting screw 6 is rotatably connected inside the second adjusting shaft 8. An adjusting knob 7 for rotating the adjusting screw 6 is fixedly connected to the other end of the adjusting screw 6. The adjusting screw 6 is threadedly connected inside the first adjusting shaft 5. In use, rotating the adjusting knob 7 causes the folding arm 3 and the fixed arm 1 to form a U-shaped fixed bracket, thus disassembling the truck. The gearbox is placed in the middle of the U-shaped fixed bracket. By rotating the first fixing bolt 4, the unthreaded end of the first fixing bolt 4 is inserted into the mounting holes on both sides of the truck gearbox for fixing. When fixing the small vehicle gearbox, first remove the two first fixing bolts 4 near the rectangular housing 19. Then, rotate the adjustment knob 7 in the opposite direction to fold the folding arm 3 until the bottom of the folding arm 3 faces away from the rectangular housing 19. At this time, loosen the fastening nut 12 to allow the adjusting plate 11 to move. After adjusting to the appropriate position, reverse the fastening nut 12 to fix the adjusting plate 11. Then, fix the small vehicle gearbox to one side with the second fixing bolt 13. When disassembling, rotate the throttle 18 and the rotating wheel 17 to drive the worm gear 15 to rotate, thereby rotating the fixed arm 1 which is fixed to the rotating shaft 14, so that the truck gearbox or the small vehicle gearbox can be rotated as needed.

[0022] like Figures 1-4 As shown, both the fixed arm 1 and the folding arm 3 have a first fixing bolt 4 for fixing the transmission connected by threads inside.

[0023] like Figures 1-4As shown, a fixing screw 22 is fixedly connected to the bottom of the folding arm 3. An adjusting plate 11 is sleeved on the side surface of the fixing screw 22. A fastening nut 12 abuts against the bottom of the adjusting plate 11, and the fastening nut 12 is threaded onto the fixing screw 22. The fastening nut 12 abuts against the adjusting plate 11 by rotating on the fixing screw 22. A second fixing bolt 13 for fixing the transmission is rotatably connected inside the adjusting plate 11. Through the folding assembly, the adjusting knob 7 is rotated, which in turn drives the adjusting screw 6 to rotate, causing the folding arm 3 to flip through the hinge with the fixing arm 1, so that the bottom of the folding arm 3 faces the side opposite to the rectangular shell 19. This allows it to be transformed into two forms, enabling the fixing of different types of transmissions, thereby improving compatibility. Through the folding assembly, the folding arm 3 can be adjusted in folding angle, enabling the fixing of truck transmissions and small vehicle transmissions. This eliminates the need to purchase different models of flipping frames and replace clamps, reducing equipment costs and improving maintenance efficiency by reducing the process of replacing clamps.

[0024] like Figures 1-4 As shown, a rotating shaft 14 is fixedly connected to one side of the fixed arm 1. A rectangular shell 19 is rotatably connected to the side surface of the rotating shaft 14. A worm gear 15 is fixedly sleeved on the side surface of one end of the rotating shaft 14 located inside the rectangular shell 19. A worm 16 is drivenly connected to the bottom of the worm gear 15. One end of the worm 16 extends out of one side of the rectangular shell 19 and is rotatably connected to the rectangular shell 19. A rotating wheel 17 is fixedly connected to the end of the worm 16 extending out of the rectangular shell 19.

[0026] like Figures 1-4 As shown, the folding components are in two groups and are symmetrically distributed along the center line of the fixed arm 1.

[0027] Working principle: When in use, rotating the adjustment knob 7 causes the folding arm 3 and the fixed arm 1 to form a U-shaped fixed bracket. The truck transmission is placed in the middle of the U-shaped fixed bracket. By rotating the first fixing bolt 4, the unthreaded end of the first fixing bolt 4 is inserted into the mounting holes on both sides of the truck transmission for fixation. When fixing the small vehicle transmission, first remove the two first fixing bolts 4 near the rectangular housing 19. Then, rotate the adjustment knob 7 in the opposite direction to fold the folding arm 3 until the bottom of the folding arm 3 faces away from the rectangular housing 19. At this time, loosening the fastening nut 12 allows the adjusting piece 11 to move. After adjusting to the appropriate position, reverse the fastening nut 12 to fix the adjusting piece 11. Then, fix the small vehicle transmission to one side with the second fixing bolt 13. When disassembling, rotating the throttle 18 and the rotating wheel 17 causes the worm gear 16 to drive the worm wheel 15 to rotate, thereby causing the fixed arm 1, which is fixed to the rotating shaft 14, to rotate, so that the truck transmission or the small vehicle transmission can be rotated as needed.
