Description

Technical Field

[0001] This application belongs to the field of end-of-life vehicle dismantling and recycling technology, specifically a tool for dismantling automotive drive shafts. Background Technology

[0002] Disassembly is ubiquitous in production activities. It is even more crucial in the recycling and processing of end-of-life vehicles. While parts from end-of-life vehicles can be reused after technical processing, this depends on their ability to be properly disassembled. Therefore, disassembly is a prerequisite for more effective recycling of end-of-life vehicle resources. When disassembling the underside of a vehicle, the engine driveshaft must be removed. However, currently, there are no suitable disassembly tools, and workers can only use ordinary pry bars, which is extremely difficult. Furthermore, the contact area between the pry bar and the driveshaft is too small, concentrating the force on a single point on the driveshaft. This often leads to damage to the transmission oil seals, housing, and driveshaft, and in severe cases, even renders the transmission, oil seal housing, and driveshaft unusable, delaying production and significantly increasing production costs.

[0003] For example, CN204997608U discloses a utility model for disassembling an automotive driveshaft, comprising a parallel abutment plate and a movable plate. The movable plate is slidably connected to the abutment plate. Both the abutment plate and the movable plate are provided with axial surface slots that match the axial surface of the automotive driveshaft. A release bolt is threaded onto the movable plate, axially penetrating the movable plate, with its end abutting against the abutment plate. A positioning mechanism is provided on the abutment plate. This utility model converts the rotational motion of the release bolt into the axial motion of the movable plate separating from the abutment plate. The mechanical structure is balanced, and the direction of the force is stable, which can greatly facilitate the disassembly of the automotive driveshaft, improve work efficiency, and reduce the risk of damage to the transmission and driveshaft.

[0004] However, the automotive driveshaft disassembly tool in this application has the problem that it is difficult to apply force during the disassembly process, making it difficult to disassemble easily. If the worker is too close to the driveshaft flange, he / she will be injured immediately if mechanical damage occurs. Utility Model Content

[0005] The purpose of this application is to provide a tool for disassembling automotive drive shafts, in order to solve the problems mentioned above, such as difficulty in applying force during disassembly, difficulty in disassembly, and the risk of injury to workers who are too close to the drive shaft flange in the event of mechanical damage.

[0006] The technical solution adopted in this application is as follows:

[0007] A tool for disassembling an automotive driveshaft includes a fixed rod, a fixed block slidably connected to the periphery of the fixed rod, a connecting handle fixedly connected to the periphery of the fixed block, a socket tool fixedly connected to the connecting handle, and a wrench tool fixedly connected to the connecting handle.

[0008] By adopting the above technical solution, this structure sets up a metal rod as a fixing rod, and sets up multiple fixing blocks on the fixing rod. The position is adjusted by sliding the fixing blocks, and the fixing is completed by clamping the side clips. The fixing blocks are connected to connecting handles, and a sleeve and a wrench are fixed at the end of the connecting handles. This design can adapt to most thread removal. During use, the fixing claw is installed on the shaft tube of the drive shaft for fixation, and then the disassembly tool is nested on the thread to be disassembled. By rotating the entire metal rod, the thread is disassembled. This not only makes disassembly easier, but also avoids potential safety hazards during disassembly due to the distance from the drive shaft, thus protecting the personal safety of the workers.

[0009] In a preferred embodiment, a rotating connecting block is rotatably connected to the side of the wrench tool, an auxiliary sliding block is fixedly installed on the front of the rotating connecting block, a fixing part is fixedly installed on the side of the auxiliary sliding block, a threaded post is fixedly installed on the side of the fixing part, and a movable part is rotatably connected to the threaded post through a nut.

[0010] By adopting the above technical solution, this structure completes the disassembly of the drive shaft by fixing an adjustable wrench to the end of the connecting handle. A rotating connecting block is installed on the side of the connecting handle for real-time adjustment of the wrench angle, which is convenient for fixing to the outside of the thread. A threaded post is fixedly installed in the center of the fixing part, and a nut is connected to the tail of the threaded post, which can adjust the size of the wrench jaw in real time. An auxiliary sliding block is nested on the side to assist the wrench in adjusting the size and reduce the pressure on the threaded post to avoid damage.

[0011] In a preferred embodiment, a rotating shaft is mounted at the tail of the connecting handle, and a fixing claw is fixedly connected to the rotating shaft.

[0012] By adopting the above technical solution, this structure has a rotating shaft connected to the end of the connecting handle to help adjust the angle of the fixing claw and prevent the fixing claw from being unable to be fixed on the shaft tube when there is an obstruction.

[0013] In a preferred embodiment, a shaft tube is fixedly connected inside the fixing claw, and a drive shaft is slidably connected to the side of the shaft tube.

[0014] By adopting the above technical solution, this structure fixes the fixed claw to the drive shaft. The multi-claw position not only ensures sufficient stability by expanding the contact area, but also avoids the situation where a single fixed claw damages the drive shaft due to excessive force.

[0015] In a preferred embodiment, a sleeve housing is fixedly installed at the end of the sleeve tool, and a large threaded hole is provided inside the sleeve housing, and a small threaded hole is provided inside the large threaded hole.

[0016] By adopting the above technical solution, this structure incorporates two different sizes of threaded holes in the sleeve disassembly tool, which can be applied to a variety of situations. The flexible installation can be used for other thread disassembly applications, further shortening working time and improving work efficiency.

[0017] In a preferred embodiment, the fixing block has a clip on its side.

[0018] By adopting the above technical solution, this structure has a clip on the side of the fixing block to assist in the installation of the fixing block and provide sufficient support.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0020] In this application, a metal rod is set as a fixing rod, and multiple fixing blocks are set on the fixing rod. The position is adjusted by sliding the fixing blocks, and the fixing is completed by clamping the side clips. The fixing blocks are connected to the connecting handles, and a sleeve and a wrench are fixed at the end of the connecting handles. This design can adapt to most thread removal. During use, the fixing claw is installed on the shaft tube of the drive shaft for fixation, and then the disassembly tool is nested on the thread to be disassembled. By rotating the whole metal rod, the thread is disassembled. This not only makes disassembly easier, but also avoids potential safety hazards during disassembly due to the distance from the drive shaft, thus protecting the personal safety of the workers.

[0028] Example:

[0029] A tool for disassembling an automotive driveshaft includes a fixed rod 1, a fixed block 2 slidably connected to the periphery of the fixed rod 1, a connecting handle 3 fixedly connected to the periphery of the fixed block 2, a socket tool 6 fixedly connected to the connecting handle 3, and a wrench tool 7 fixedly connected to the connecting handle 3. This structure uses a metal rod as the fixed rod, with multiple fixed blocks on it. The position is adjusted by sliding the fixed blocks, and the tool is fixed by clamping the side clips. The fixed blocks are connected to the connecting handle, and a socket and a wrench tool are fixed to the end of the connecting handle. This design can accommodate most thread removal operations. During use, the fixing claw is installed on the driveshaft tube for fixation, and the disassembly tool is nested on the thread to be disassembled. Rotating the entire metal rod drives the disassembly of the thread. This design not only makes disassembly easier but also avoids potential safety hazards during disassembly due to the distance from the driveshaft, protecting the personal safety of the workers.

[0030] The wrench tool 7 has a rotating connecting block 701 rotatably connected to its side. An auxiliary sliding block 706 is fixedly installed on the front of the rotating connecting block 701. A fixing part 702 is fixedly installed on the side of the auxiliary sliding block 706. A threaded post 703 is fixedly installed on the side of the fixing part 702. The threaded post 703 is rotatably connected to a movable part 705 via a nut 704. This structure completes the disassembly of the drive shaft by fixing an adjustable wrench to the end of the connecting handle. The rotating connecting block is installed on the side of the connecting handle for real-time adjustment of the wrench angle, which is convenient for fixing it to the outside of the thread. The threaded post is fixedly installed in the center of the fixing part. The tail of the threaded post is connected to a nut, which can adjust the size of the wrench jaw in real time. The auxiliary sliding block is nested on the side to assist in adjusting the size of the wrench and reduce the pressure on the threaded post to avoid damage.

[0031] A rotating shaft 4 is installed at the tail of the connecting handle 3. A fixing claw 5 is fixedly connected to the rotating shaft 4. This structure has a rotating shaft connected to the end of the connecting handle to help the fixing claw adjust the angle and prevent the fixing claw from being unable to be fixed on the shaft tube when there are obstructions.

[0032] The fixed claw 5 is internally fixedly connected to the shaft tube 801, and the shaft tube 801 is slidably connected to the side of the drive shaft 8. This structure fixes the fixed claw to the drive shaft. The multi-claw position setting not only ensures sufficient stability by expanding the contact area, but also avoids the situation where a single fixed claw damages the drive shaft due to excessive force.

[0033] The end of the socket tool 6 is fixedly installed with a socket housing 601. The socket housing 601 has a large threaded hole 603 inside, and the large threaded hole 603 has a small threaded hole 602 inside. This structure has two different sizes of threaded holes nested in the socket disassembly tool, which can be applied to a variety of situations. The flexible installation can be used for other thread disassembly, further shortening the working time and improving work efficiency.

[0034] The side of the fixing block 2 is provided with a clip 201. The clip on the side of the fixing block is used to assist the installation of the fixing block and provide sufficient support.

[0035] The implementation principle of an embodiment of an automotive driveshaft disassembly tool of this application is as follows: a fixing block 2 is slidably connected to the periphery of a fixing rod 1, a connecting handle 3 is fixedly connected to the periphery of the fixing block 2, a sleeve tool 6 is fixedly connected to the connecting handle 3, and a wrench tool 7 is fixedly connected to the connecting handle 3. This structure sets up a metal rod as a fixing rod, and sets multiple fixing blocks on the fixing rod. The position is adjusted by sliding the fixing blocks, and the fixing is completed by clamping the side clips. The fixing blocks are connected to the connecting handle, and the sleeve and wrench tool are fixed at the end of the connecting handle. This setting can adapt to most thread removal. In the process of use, the fixing claw is installed on the shaft tube of the driveshaft for fixation, and then the disassembly tool is nested on the thread to be disassembled. By rotating the whole metal rod, the thread is disassembled. This not only makes disassembly easier, but also avoids potential safety hazards during disassembly due to the distance from the driveshaft, thus protecting the personal safety of the workers.
