Description

A tooling for a gearbox shifting mechanism Technical Field

[0001] This utility model relates to the field of automotive assembly technology, and more specifically, to a tooling for a gearbox shifting mechanism. Background Technology

[0002] With the rapid development of the automotive industry, automatic transmissions have become a mainstream configuration in modern vehicles due to their ease of operation and driving comfort. As a core component, the shift mechanism of an automatic transmission directly affects the smoothness of shifting, transmission efficiency, and overall lifespan. Currently, in automobile production, the prerequisite for assembling the transmission shift panel is that the shift mechanism must be in the neutral (N) position to ensure the vehicle is in a standard state during assembly. In existing technology, workers typically determine the paddle positions visually. However, visually inspecting the shift levers cannot accurately determine the current gear position of the paddles, failing to standardize the paddle assembly process. If the paddles are not in the neutral (N) position after assembly, disassembly and reassembly are required, wasting manpower and resources. Furthermore, visual assembly heavily relies on worker experience; achieving accurate visual judgment requires extensive training, increasing training costs. Summary of the Invention

[0003] To address the technical problem of not being able to determine the position of the shift paddles in existing technologies, this utility model provides a tooling for a gearbox shifting mechanism, which can assist workers in determining the neutral position of the shift paddles in the automatic transmission gearbox shifting mechanism, thereby improving the assembly speed and accuracy of the gearbox.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a gearbox shifting mechanism tooling, including a tooling body, the tooling body having a snap-fit ​​groove for engaging with a shift paddle, a first fixing plate and a second fixing plate respectively provided at both ends of the tooling body, the first fixing plate and the second fixing plate being parallel and perpendicular to the tooling body, and both the first fixing plate and the second fixing plate abutting against the side wall surface of the TCU part in the automotive gearbox.

[0005] In this technical solution, the tooling body is used to install and fix various parts. A first fixing plate and a second fixing plate are respectively installed at both ends of the tooling body. The first fixing plate, the second fixing plate, and the tooling body together form a downward-facing fork-shaped structure. The automotive transmission contains a TCU component, and shift paddles are mounted on the TCU component. During use, the operator inserts the TCU component into the fork-shaped structure, thereby installing the transmission shifting mechanism tooling onto the TCU component. The first fixing plate and the second fixing plate are respectively clamped on opposite sides of the TCU component. After the transmission shifting mechanism tooling is installed, the first fixing plate and the second fixing plate abut against the outside of the TCU component, generating friction and ultimately fixing the transmission shifting mechanism tooling onto the TCU component. When it is necessary to disassemble the transmission shifting mechanism tooling, the operator only needs to lift the tooling to separate it from the TCU component. The disassembly process is simple and quick, greatly improving the efficiency of using the transmission shifting mechanism tooling. The tooling body is provided with a locking groove, the position and shape of which are set according to the shape of the shift paddles and the neutral position. When assembling paddle shifters, simply install the gearbox shift mechanism tooling onto the TCU component first, then engage the paddle shifters with the engaging slots. The engaging slots determine the horizontal position of the paddle shifters. Finally, install the paddle shifters onto the TCU component; at this point, the paddle shifters are in the neutral position. The entire assembly process is simple and quick. Workers can refer to the physical structure of the engaging slots to ensure the paddle shifters are in the neutral position, avoiding errors caused by visual inspection. This improves the efficiency and accuracy of paddle shifter installation. Furthermore, the easily observable and measurable structure of the engaging slots reduces assembly difficulty and eliminates the need for extensive experience, thus lowering training costs.

[0006] Preferably, the snap-fit ​​groove has a U-shaped structure, the snap-fit ​​groove penetrates the tooling body in the vertical direction, and the two opposite groove walls of the snap-fit ​​groove are fixed surfaces, which are used to abut against the side of the shift paddle.

[0007] Preferably, a pad is fixedly installed on the bottom surface of the tooling body, the pad is located between the first fixing plate and the second fixing plate, and the pad is used to abut against the top surface of the TCU part of the automotive gearbox.

[0008] Preferably, the tooling body is provided with a first mounting hole that penetrates the tooling body, and the upper surface of the pad is provided with a second mounting hole. Both the first mounting hole and the second mounting hole are threaded holes. The tooling body is also provided with a fastening bolt, which is inserted into the first mounting hole and the second mounting hole in sequence and threadedly connected to the first mounting hole and the second mounting hole.

[0009] Preferably, the pad is covered with a first rubber sleeve.

[0010] Preferably, the end of the tooling body is also provided with a notch.

[0011] Preferably, a second rubber sleeve is fitted on both the first fixing plate and the second fixing plate, and the second rubber sleeve abuts against the side wall surface of the TCU part.

[0012] Preferably, the tooling body, the first fixing plate, and the second fixing plate are all made of cast iron.

[0013] Preferably, the upper surface of the tooling body is also provided with a gripping component that facilitates the worker's gripping.

[0014] Preferably, the gripper has a spherical structure, and a third mounting hole is provided at the bottom of the gripper. The third mounting hole is a threaded hole, and a threaded post is provided on the tooling body. The threaded post is threadedly connected to the third mounting hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, by setting a snap-fit ​​groove on the tooling body to engage with the shift paddle, the operator can determine the neutral position of the shift paddle during assembly through the snap-fit ​​groove, which greatly improves the assembly speed and accuracy of the gearbox, reduces the experience requirements of the operator, and saves on operator training costs. The gearbox shift mechanism tooling is clamped to the TCU parts by the first and second fixing plates, making installation and disassembly more convenient and improving the utilization efficiency of the gearbox shift mechanism tooling.

[0022] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0023] Example 1

[0024] As shown in Figures 1 and 2, a gearbox shifting mechanism fixture includes a fixture body 1. The fixture body 1 has a locking groove 2 for engaging with a gearbox shift paddle 7. A first fixing plate 3 and a second fixing plate 4 are respectively provided at both ends of the fixture body 1. The first fixing plate 3 and the second fixing plate 4 are parallel and perpendicular to the fixture body 1, and both the first fixing plate 3 and the second fixing plate 4 abut against the side wall of the TCU component 8 in the automotive gearbox. The fixture body 1 is used to install and fix various components. The first fixing plate 3 and the second fixing plate 4 are respectively installed at both ends of the fixture body 1, and the first fixing plate 3, the second fixing plate 4, and the fixture body 1 together form a downward-facing fork-shaped structure. The automotive gearbox contains a TCU component 8, and the shift paddle 7 is installed on the TCU component 8. During use, the operator inserts the TCU component 8 into the fork-shaped structure, thereby installing the gearbox shifting mechanism fixture onto the TCU component 8. The first fixing plate 3 and the second fixing plate 4 are respectively clamped on opposite sides of the TCU part 8. After the gearbox shift mechanism fixture is installed, the first fixing plate 3 and the second fixing plate 4 abut against the outside of the TCU part 8, thereby generating friction between them and the TCU part 8, ultimately fixing the gearbox shift mechanism fixture onto the TCU part 8. When it is necessary to disassemble the gearbox shift mechanism fixture, the operator only needs to lift the gearbox shift mechanism fixture directly to separate it from the TCU part 8. The disassembly process is simple and quick, greatly improving the efficiency of the gearbox shift mechanism fixture. The fixture body 1 is provided with a snap-fit ​​groove 2. The position and shape of the snap-fit ​​groove 2 are set according to the shape of the shift paddle 7 and the neutral position. When assembling the paddle shifter 7, simply install the gearbox shift mechanism tooling on the TCU part 8 first, then engage the paddle shifter 7 with the engaging slot 2. The engaging slot 2 determines the horizontal position of the paddle shifter 7. Then, install the paddle shifter 7 on the TCU part 8. At this point, the paddle shifter 7 is in the neutral position. The entire assembly process is simple and quick. Workers can refer to the physical structure of the engaging slot 2 to ensure the paddle shifter 7 is in the neutral position, avoiding errors caused by visual inspection. This improves the efficiency and accuracy of paddle shifter 7 installation. Furthermore, the easily observable and measurable physical structure of the engaging slot 2 reduces assembly difficulty and eliminates the need for extensive experience, thus lowering training costs.

[0025] As shown in Figure 1, the locking groove 2 has a U-shaped structure and penetrates the tooling body 1 vertically. The two opposite groove walls of the locking groove 2 are fixed surfaces 21, which are used to abut against the side of the shift paddle 7. The two fixed surfaces 21 of the locking groove 2 are set according to the neutral position of the shift paddle 7. The two fixed surfaces 21 are respectively clamped on both sides of the shift paddle 7 to fix the position of the shift paddle 7, thereby determining the position of the shift paddle 7.

[0026] As shown in Figure 3, a pad 5 is fixedly installed on the bottom surface of the fixture body 1. The pad 5 is located between the first fixed plate 3 and the second fixed plate 4, and abuts against the top surface of the TCU part 8. The pad 5 is used to determine the vertical position of the fixture body 1, ensuring that the snap-fit ​​groove 2 on the fixture body 1 and the shift paddle 7 are on the same horizontal plane. At the same time, the pad 5 provides support for the fixture body 1, thereby ensuring the stability of the transmission shifting mechanism fixture during use.

[0027] As shown in Figures 1 and 3, the fixture body 1 has a first mounting hole that penetrates through it. The upper surface of the pad 5 has a second mounting hole. Both the first and second mounting holes are threaded holes. The fixture body 1 also has fastening bolts 11, which are inserted into the first and second mounting holes and threadedly connected to them. The pad 5 is mounted on the fixture body 1 using the fastening bolts 11, facilitating installation and removal by the operator. By replacing pads 5 with those of different heights, the operator can fix the fixture body 1 at different heights, allowing the gearbox shift mechanism fixture to accommodate shift paddles 7 at different installation heights.

[0028] As shown in Figure 3, a first rubber sleeve is fitted over the pad 5. This first rubber sleeve serves two purposes: firstly, it protects the pad 5 from collisions with the TCU component 8, preventing scratches; secondly, it increases the friction between the pad 5 and the TCU component, ensuring the stable position of the gearbox shift mechanism fixture during the paddle shifter 7 assembly process. This prevents accidental movement of the gearbox shift mechanism fixture, thus avoiding assembly deviations of the paddle shifter 7.

[0029] Example 2

[0030] This embodiment is similar to Embodiment 1 above, except that, as shown in Figures 1 and 2, a notch 12 is also provided at the end of the tooling body 1. The TCU part 8, which is connected to the shift paddle 7, is also connected to other automotive components via a wiring harness. The wiring harness occupies a certain space on the surface of the TCU part 8, and the gearbox shift mechanism tooling, installed on the surface of the TCU part 8, also occupies a certain space. This will cause interference between the wiring harness and the gearbox shift mechanism tooling, affecting the installation and normal operation of the gearbox shift mechanism tooling. Therefore, a notch 12 is provided on the tooling body 1. The notch 12 ensures the connection between the various parts of the tooling body 1 while providing a certain space to accommodate the wiring harness, thus avoiding interference between the two.

[0031] As shown in Figure 1, a second rubber sleeve is fitted onto both the first fixing plate 3 and the second fixing plate 4, and the second rubber sleeve abuts against the side wall surface of the TCU part 8. The second rubber sleeve protects the first fixing plate 3 and the second fixing plate 4, preventing them from scratching the surface of the TCU part 8. On the other hand, the surface of the second rubber sleeve is relatively rough, and it has a large frictional force after abutting against the surface of the TCU part 8, thus achieving an auxiliary fixing effect. This ensures that the position of the gearbox shift mechanism fixture remains stable during the assembly of the shift paddle 7, and that the assembly of the shift paddle 7 will not be deviated due to accidental movement of the gearbox shift mechanism fixture.

[0032] As shown in Figure 1, the tooling body 1, the first fixing plate 3, and the second fixing plate 4 are all made of cast iron. Cast iron has excellent impact resistance, and the tooling body 1, the first fixing plate 3, and the second fixing plate 4, all made of cast iron, can maintain structural stability and withstand a certain degree of external impact, ensuring that their shape does not change. This, in turn, ensures the accuracy and service life of the gearbox shifting mechanism tooling.

[0033] Example 3

[0034] This embodiment is similar to Embodiment 1 above, except that, as shown in Figure 1, the upper surface of the tooling body 1 is also provided with a gripping member 6 for easy handling by the operator. By providing the gripping member 6 on the tooling body 1, the operator can easily pick up, hold, and install the gearbox shifting mechanism tooling, thus improving the operator's comfort when using the gearbox shifting mechanism tooling.

[0035] As shown in Figure 1, the gripper 6 has a spherical structure with a third mounting hole at its bottom. This third mounting hole is threaded, and a threaded post is mounted on the fixture body 1. The threaded post is threaded into the third mounting hole. The spherical structure conforms to the shape of the human hand, improving comfort during use. Furthermore, its smooth surface eliminates sharp edges, preventing accidental cuts or punctures and ensuring safety. The gripper is detachably connected to the threaded post on the fixture body 1 via the third mounting hole. This connection ensures a secure bond between the gripper 6 and the fixture body 1 while allowing for easy disassembly and replacement of the gripper 6 by the operator.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
