Description

Technical Field

[0001] This utility model relates to the technical field of torque converter repair equipment, and in particular to a torque converter repair workbench. Background Technology

[0002] As a key component of hydraulic transmission systems, torque converters utilize the kinetic energy of fluids to transmit and convert torque. During the operation of vehicles and various industrial equipment, the mechanical energy output from the engine drives the pump impeller to rotate at high speed. The pump impeller transfers this mechanical energy to the working fluid, giving the fluid high-speed kinetic energy. The high-speed flowing fluid impacts the turbine, thereby driving the turbine and its connected output shaft to rotate, completing the power output. Because the pump impeller operates at high speeds for extended periods, enduring the powerful torque from the engine and the high-speed scouring of the fluid, its blades are highly susceptible to surface material loss due to wear. When wear reaches a certain level, cracks easily form in stress concentration areas. The turbine, due to frequent exposure to alternating torque, also frequently develops cracks at weak points such as the blade roots under long-term fatigue.

[0003] Currently, welding is a common method for repairing cracks in the pump impeller and turbine of torque converters. When welding to repair torque converters, the converter is usually fixed to a workbench before welding. However, current workbenches generally lack a rotating mechanism, meaning that adjusting the torque converter angle relies solely on manual operation, which is very inconvenient. Furthermore, manual adjustment leads to low maintenance efficiency and difficulty in guaranteeing welding quality.

[0004] A utility model application with application number CN201820845036.3 discloses a maintenance bracket for a torque converter, comprising a body, clamping plates, and a base. The base is fixedly connected to the bottom of the body. A first support rod is fitted inside each spring, and the bottom of the first support rod is fixedly connected to a connecting block. A slider is slidably engaged with a sliding groove. Clamping plates are fixedly connected to the front of each slider, and the inner upper end of each clamping plate is fitted against the body. Bolts penetrate the clamping plates and are tightly connected to the body. However, in use, the torque converter angle can only be adjusted manually, resulting in inconvenient angle adjustment, low maintenance efficiency, and difficulty in ensuring the quality of welding repairs.

Detailed Implementation

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] Example:

[0032] like Figures 1 to 3 As shown, in order to solve the above problems, this embodiment discloses a torque converter maintenance workbench, including a mounting platform 10, a rotating component 20 and a fixed component 30, wherein the rotating component 20 and the fixed component 30 are disposed together on the mounting platform 10.

[0033] The rotating assembly 20 includes a rotating disk 200 and a rotating drive structure 201. The rotating disk 200 is disposed on the rotating drive structure 201, and the rotating drive structure 201 is used to drive the rotating disk 200 to rotate.

[0034] The fixing assembly 30 includes a fixing disk 300, a fixing rod 301, and a height adjustment structure 302. The fixing disk 300 is located above the rotating disk 200, and the center of the fixing disk 300 and the center of the rotating disk 200 are on the same axis. One end of the fixing disk 300 is fixedly connected to one end of the fixing rod 301, and the other end of the fixing rod 301 is rotatably mounted on the height adjustment structure 302. The height adjustment structure 302 is used to adjust the height of the fixing rod 301 and the fixing disk 300. The fixing disk 300 can cooperate with the rotating disk 200 to fix the torque converter.

[0035] In use, this invention simply requires placing the torque converter on the rotating disk 200. The height of the fixing rod 301 is then adjusted via the height adjustment structure 302, which in turn drives the fixing disk 300, pressing the torque converter onto the rotating disk 200 to secure it. When adjusting the torque converter's angle, the rotating disk 200 is simply driven to rotate via the rotation drive structure 201, causing the torque converter, fixing disk 300, and fixing rod 301 to rotate synchronously, thus adjusting the torque converter's angle and facilitating welding at different angles. This solves the problems of current torque converter worktables, where angle adjustment is only possible manually, leading to inconvenience, low maintenance efficiency, and difficulty in guaranteeing welding quality.

[0036] like Figures 5 to 7As shown, to facilitate driving the rotating disk 200, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the rotating drive structure 201 includes a mounting box 202, a mounting base 203, a rotating shaft 204, and a drive component 205. The top of the mounting platform 10 is provided with a mounting table 100, and the mounting table 100 is provided with a mounting window 101 that penetrates through the mounting table 100. The mounting base 203 is fixedly installed on the top of the mounting table 100, and one end passes through the mounting window 101. The top of the mounting box 202 is provided with an opening 206. The mounting box 202 is fixedly connected to the bottom of the mounting table 100 and is configured to cooperate with the mounting base 203. The rotating shaft 204 is set inside the mounting box 202. One end of the rotating shaft 204 passes through the top of the mounting box 202 and is rotatably connected to the bottom of the mounting box 202. The other end of the rotating shaft 204 passes through the mounting base 203 and is rotatably connected to the mounting base 203. The rotating disk 200 is fixedly set at the end of the rotating shaft 204 that passes through the mounting base 203. The driving component 205 is set on the mounting box 202 and is configured to cooperate with the rotating shaft 204 to drive the rotating shaft 204 to rotate.

[0037] The driving component 205 includes a drive motor 207, a worm gear 208, and a worm 209. The worm gear 208 and worm 209 are disposed within the mounting housing 202. The worm gear 208 is sleeved on and fixedly connected to the rotating shaft 204. The worm 209 is disposed on one side of the worm gear 208 and is configured to cooperate with the worm gear 208. Both ends of the worm 209 pass through the mounting housing 202 and are rotatably connected to the mounting housing 202. The drive motor 207 is fixedly disposed on one side of the mounting housing 202, and the output shaft of the drive motor 207 is fixedly connected to one end of the worm 209 for driving the worm 209. The worm 209 and the worm gear 208 are driven by meshing.

[0038] In use, the drive motor 207 drives the worm gear 209 to rotate via its output shaft. The worm gear 209 meshes with the worm wheel 208, causing the worm wheel 208, which is fixedly sleeved on the rotating shaft 204, to rotate synchronously. The rotating shaft 204 achieves stable rotation through a double rotational connection with the mounting base 203 and the mounting housing 202, ultimately driving the rotating disk 200 fixed at the end of the rotating shaft 204 to perform circular motion. The meshing transmission of the worm wheel 208 and worm gear 209 makes the rotation of the rotating shaft 204 more stable, thereby making the rotation of the rotating disk 200 more stable. It should be noted that the drive motor 207 can be a variable frequency motor that can achieve the functions of this invention, as is available in the prior art.

[0039] like Figures 2 to 3As shown, to facilitate the fixing of the torque converter, this embodiment is modified based on the above embodiment. The difference lies in that the height adjustment structure 302 includes a mounting bracket 303, a mounting shell 304, and a drive cylinder 305. The mounting bracket 303 is fixedly mounted on the mounting base 203, and its lower end cooperates with the rotating disk 200. The mounting shell 304 is fixedly mounted on the mounting bracket 303 and located above the rotating disk 200. The mounting shell 304 has a mounting cavity 306 that penetrates the top and bottom of the mounting shell 304. A pair of support brackets 305 are provided inside the mounting cavity 306. 7. A pair of support frames 307 are respectively fixedly installed at the upper and lower ends of the mounting cavity 306. A drive cylinder 305 is fixedly installed on the support frame 307 located at the upper end of the mounting cavity 306. The output shaft of the drive cylinder 305 passes through the support frame 307 located at the upper end of the mounting cavity 306 and is slidably connected to the support frame 307. A fixing rod 301 is installed between the pair of support frames 307. One end of the fixing rod 301 connected to the fixing plate 300 passes through the support frame 307 located at the lower end of the mounting cavity 306 and is clearance-fitted with the support frame 307. The other end of the fixing rod 301 is rotatably connected to the end of the output shaft of the drive cylinder 305.

[0040] In use, the fixed rod 301 can be driven by the output shaft of the drive cylinder 305, thereby adjusting the height of the fixed disk 300 connected to the fixed rod 301. When the fixed disk 300 fixes the torque converter on the rotating disk 200, the rotation of the rotating disk 200 drives the torque converter to rotate, which in turn drives the fixed disk 300 and the fixed rod 301 to rotate. The drive cylinder 305 can be any cylinder in the prior art that can achieve the function of this utility model.

[0041] It should be noted that the clearance fit between the fixing rod 301 and the support frame 307 at the lower end of the mounting cavity 306 means that the fixing rod 301 and the support frame 307 at the lower end of the mounting cavity 306 can be slidably and rotatably connected.

[0042] To facilitate the protection of the end faces of the torque converter that contact the fixed disk 300 and the rotating disk 200, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the fixed disk 300 and the rotating disk 200 are provided with a number of flexible rubber strips 308 at the end that contacts the torque converter.

[0043] Among them, a number of flexible rubber strips 308 on the fixed disk 300 are arranged in a circular array around the center of the fixed disk 300, and a number of flexible rubber strips 308 on the rotating disk 200 are arranged in a circular array around the center of the rotating disk 200.

[0044] Several flexible rubber strips 308 are attached to the fixed plate 300 and the rotating plate 200.

[0045] During use, the arrangement of several flexible rubber strips 308 facilitates the protection of the torque converter end face, preventing damage. The circumferential array arrangement effectively disperses contact pressure. The adhesive mounting method allows for easy replacement of the flexible rubber strips 308.

One end of the placement ring 503 is fixedly connected to one side of the adjusting head 502. The placement ring 503 is provided with a placement opening 505 that cooperates with the welding gun 401. The welding gun 401 can be placed in the placement opening 505.

[0049] By setting up the placement rack 50, it is convenient to access the welding gun 401 during welding and to place the welding gun 401 when not in use.
