[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0031] This utility model provides a moving tooling for a gearbox wheelset assembly, the structure of which is as follows: Figure 1 - Figure 8 As shown, it includes a movable frame 11, an upper positioning head 21, a drive assembly 22, and a lower positioning head 41.

[0032] The movable frame 11 has an upper positioning seat 12 and a lower positioning seat 13 extending to the top and bottom of the gearbox 3, respectively.

[0033] The upper positioning head 21 is connected to the upper positioning seat 12 and has a first connecting end 23 that can be detachably connected to the nut 31 on the top of the gearbox 3.

[0034] The fixed end of the drive component 22 is connected to the upper positioning seat 12, and the movable end of the drive component 22 is connected to the upper positioning head 21.

[0035] The lower positioning head 41 is connected to the lower positioning seat 13 and has a second connecting end 44 that can be detachably connected to the nut 32 at the bottom of the gearbox 3.

[0036] In use, the fixed end of the drive assembly 22 is connected to the upper positioning seat 12, and the movable end is connected to the upper positioning head 21. When it is necessary to position or fix the gearbox 3, the drive assembly 22 is activated, and its movable end drives the upper positioning head 21 to move, so that the upper positioning head 21 is adapted to and tightly engaged with the nut 31 on the gearbox 3. In this way, the upper positioning head 21 can hold the nut 31, restricting some degrees of freedom of movement of the gearbox 3 in the vertical and horizontal directions, ensuring that the gearbox 3 maintains a relatively fixed position above the tooling. The lower positioning head 41 is connected to the lower positioning seat 13 and is adapted to the nut 32 on the gearbox 3. When the tooling moves to a suitable position below the gearbox 3 wheelset assembly, the lower positioning head 41 aligns and engages with the nut 32 at the bottom of the gearbox 3. Since the lower positioning head 41 is fixed on the lower positioning seat 13, it can support and fix the gearbox 3 from below. Together with the upper positioning head 21, it further restricts the movement of the gearbox 3, so that the gearbox 3 is well positioned and fixed in both the vertical and horizontal directions, ensuring the stability of the gearbox 3 during movement.

[0037] In this utility model, the upper positioning head 21 and the lower positioning head 41 are detachably connected to the top and bottom of the gearbox 3, respectively. Before moving the gearbox 3, simply lift the gearbox 3 and then place the upper positioning head 21 and the lower positioning head 41 on the top and bottom of the gearbox 3, respectively. This makes the operation convenient and improves work efficiency.

[0038] To improve the overall strength of the tooling, please refer to... Figure 3 In a preferred embodiment, the movable tooling further includes a support plate 14, one side of which is connected to the lower positioning seat 13, and the other side of which is connected to the movable frame 11.

[0039] During use, the lower positioning seat 13 and the moving frame 11 may be subjected to various external forces during the operation of the moving fixture, such as the weight of the object being moved and the impact force during the movement. The support plate 14 can share these external forces and transfer them to the lower positioning seat 13 and the moving frame 11, thereby reducing the pressure on individual components.

[0040] To drive the upper positioning head 21 to rise and fall, please refer to... Figure 3 In a preferred embodiment, the drive assembly 22 includes a screw 221, which is threadedly connected to the upper positioning seat 12, and the upper positioning head 21 is connected to the screw 221.

[0041] In use, the upper positioning head 21 is connected to the screw 221. When the screw 221 rotates and produces linear motion, it will drive the upper positioning head 21 to move along the axis of the screw 221. If the screw 221 rotates clockwise, it will gradually move downward, thus pushing the upper positioning head 21 downward, so that the upper positioning head 21 approaches and matches the nut 31 on the gearbox 3, thereby achieving the positioning or fastening operation of the gearbox 3. Conversely, when the screw 221 rotates counterclockwise, it moves upward, driving the upper positioning head 21 upward, so that the upper positioning head 21 separates from the nut 31, so that the positioning of the gearbox 33 can be released when needed.

[0042] To improve the stability of screw 221, please refer to... Figure 3 In a preferred embodiment, the drive assembly 22 further includes a locking nut 32222, which is threaded onto the screw 221 and abuts against the upper positioning seat 12.

[0043] During use, after the screw 221 moves the upper positioning head 21 to a suitable position, ensuring accurate engagement between the upper positioning head 21 and the nut 31 on the gearbox 3 for positioning or tightening, the position of the screw 221 needs to be fixed to prevent rotation due to vibration, external forces, or other factors, which could alter the position of the upper positioning head 21 and affect the positioning effect on the gearbox 3. At this point, the locking nut 32222 is rotated to move along the thread direction on the screw 221 until it abuts against the upper positioning seat 12. Because the locking nut 32222 is in close contact with the upper positioning seat 12, a force is generated along the axial direction of the screw 221. This force prevents the screw 221 from rotating relative to the upper positioning seat 12, thus firmly fixing the position of the screw 221 and ensuring that the upper positioning head 21 remains in the designated position, maintaining stable positioning of the gearbox 3.

[0044] To achieve the detachable connection of the upper positioning head 21, please refer to... Figure 6 In a preferred embodiment, the drive assembly 22 further includes a pin 223 and a first pin 224. The pin 223 is connected to the screw 221 and passes through the upper positioning head 21. The first pin 224 passes through the pin 223 and abuts against the upper positioning head 21.

[0045] In use, the pin 223 is connected to the screw 221 and passes through the upper positioning head 21. This connection method creates a movable connection structure between the screw 221 and the upper positioning head 21. The first pin 224 passes through the pin 223 and abuts against the upper positioning head 21. The main function of the first pin 224 is to prevent the pin 223 from coming off the positioning head.

[0046] To achieve the detachable connection of the lower positioning head 41, please refer to... Figure 8 In a preferred embodiment, the movable fixture further includes a bolt 42 and a second pin 43. The bolt 42 is threaded onto the lower positioning seat 13 and passes through the lower positioning head 41. The second pin 43 passes through the bolt 42 and abuts against the lower positioning head 41.

[0047] In use, bolt 42 is threaded onto lower positioning seat 13 and passes through lower positioning head 41, establishing a connection between lower positioning head 41 and lower positioning seat 13. Second pin 43 abuts against lower positioning head 41, providing additional security for the entire connection structure. By limiting the axial movement of bolt 42, it ensures that bolt 42 remains in the correct position, making the connection between lower positioning head 41 and lower positioning seat 13 more reliable.

[0048] To improve the strength of mobile tooling, please refer to... Figure 3In a preferred embodiment, the movable tooling further includes a reinforcing plate 15, one end of which is connected to the support plate 14, and the other end of which is connected to the lower positioning seat 13.

[0049] During use, the reinforcing plate 15 plays a role in strengthening and stabilizing, forming a more stable overall structure between the support plate 14 and the lower positioning seat 13.

[0050] To accommodate different sizes of nuts 31 and nut 32, please refer to [reference needed]. Figure 6 In a preferred embodiment, both the upper positioning head 21 and the lower positioning head 41 include a support 5, a plurality of clamps 6 and a fixing component 7. The plurality of clamps 6 are arranged around the support 5 and are slidably connected to the support 5 along the radial direction of the support 5. The fixing component 7 is used to fix the clamps 6 to the support 5.

[0051] When in use, the sizes of the nuts 31 and 32 on the gearbox 3 are different for different models of gearbox 3. The chuck 6 is slidably connected to the support 5. According to the size of the nuts 31 and 32, the spacing of multiple chucks 6 is adjusted, and then the chuck 6 is fixed by the fixing component 7. This allows it to be adapted to different models of gearbox 3, improving the adaptability of the tooling.

[0052] To adjust the spacing between the multiple clamps 6, please refer to... Figure 7 In a preferred embodiment, the fixing component 7 includes a locking block 71 and a spring 72. The locking block 71 is slidably connected to the clamp 6, and the spring 72 is sleeved on the clamp 6. One end of the spring 72 is connected to the clamp 6, and the other end of the spring 72 is connected to the locking block 71. The support 5 is provided with a plurality of slots 73 for accommodating the locking block 71 at intervals along the sliding direction of the clamp 6. The spring 72 is in a compressed state, and the spring 72 causes the locking block 71 to tend to slide towards the slots 73.

[0053] In use, according to the size of the nut 31 and the screw 32, push the chuck 6 to slide. After the chuck 6 is slid to the predetermined position, release the locking block 71. Under the action of the restoring force of the spring 72, the locking block 71 slides into the corresponding slot 73, and the chuck 6 is fixed.

[0054] To make it easier for the card block 71 to slide into the card slot 73, please refer to... Figure 8 In a preferred embodiment, the side of the card block 71 near the card slot 73 is provided with a rounded chamfer.

[0055] During use, the rounded chamfer makes the edge of the locking block 71 smoother as it approaches the slot 73. When the chuck 6 slides and the locking block 71 moves toward the slot 73 under the elastic force of the spring 72, the rounded chamfer reduces the friction and collision resistance between the locking block 71 and the edge of the slot 73, making it easier and smoother for the locking block 71 to enter the slot 73.

[0056] To better understand this utility model, the following is combined with... Figure 1 - Figure 8 The working principle of a gearbox 3 wheelset assembly moving fixture according to the present invention is described in detail below: The fixed end of the drive assembly 22 is connected to the upper positioning seat 12, and the movable end is connected to the upper positioning head 21. When it is necessary to position or fix the gearbox 3, the drive assembly 22 is activated, and its movable end drives the upper positioning head 21 to move, so that the upper positioning head 21 is adapted to and tightly fitted with the nut 31 on the gearbox 3. In this way, the upper positioning head 21 can lock the nut 31, restricting some degrees of freedom of movement of the gearbox 3 in the vertical and horizontal directions, ensuring that the gearbox 3 maintains a relatively fixed position above the fixture. The lower positioning head 41 is connected to the lower positioning seat 13 and is adapted to the nut 32 on the gearbox 3. When the fixture moves to a suitable position below the gearbox 3 wheelset assembly, the lower positioning head 41 aligns and engages with the nut 32 at the bottom of the gearbox 3. Since the lower positioning head 41 is fixed on the lower positioning seat 13, it can support and fix the gearbox 3 from below. Together with the upper positioning head 21, it further restricts the movement of the gearbox 3, so that the gearbox 3 is well positioned and fixed in both the vertical and horizontal directions, ensuring the stability of the gearbox 3 during movement.
