[0001] This utility model belongs to the technical field of auxiliary assembly devices, and in particular relates to an auxiliary assembly device for a large vehicle traveling mechanism. Background Technology

[0002] The auxiliary assembly device for the traveling mechanism of a large trolley mainly includes the following core components:

[0003] 1. PLC control unit: As the control center of the system, it is responsible for sending control signals and coordinating the movement of various auxiliary assembly devices.

[0004] 2. Y-axis operating platform: This platform is equipped with two X-axis operating platforms, which can be raised and lowered or tilted along the Y-axis through a lifting mechanism to adjust the position of the wheel assembly in the Y-axis direction.

[0005] 3. X-axis direction operation platform: Each X-axis direction operation platform is equipped with a support platform, which realizes movement along the X-axis direction through slide rails and sliders, and is used to adjust the position of the wheel assembly in the X-axis direction.

[0006] 4. Support platform: Used to support wheel assemblies and clamping fixtures, ensuring the stability of wheel assemblies during assembly.

[0007] 5. Clamping fixture: Used to clamp the wheel assembly to prevent it from moving or tipping over during assembly, ensuring smooth assembly.

[0008] 6. Wheel assembly support frame: Located at the front end of the support platform, it is used to place wheel assemblies to ensure the correct position and orientation of the wheel assemblies before assembly.

[0009] 7. Triaxial Transfer Machine: A gantry-type hoisting equipment used to hoist wheel assemblies and trolley frames, enabling their rapid transfer between different workstations.

[0011] The thickness of existing wheel assembly materials may vary depending on different specifications or models. Traditional wheel assembly supports are fixed in size and cannot be adjusted, making them unsuitable for accommodating wheels of varying thicknesses and hindering stable wheel mounting, thus affecting assembly accuracy and stability. Therefore, we propose an auxiliary assembly device for large vehicle traveling mechanisms. Utility Model Content

[0012] The purpose of this utility model is to provide an auxiliary assembly device for a large vehicle traveling mechanism to solve the problems mentioned in the background art.

[0013] In view of this, the present invention provides an auxiliary assembly device for a large vehicle traveling mechanism, comprising:

[0014] The base and two normal frames are fixedly connected to the base. One side of the inner wall of the base is provided with multiple first sliding grooves, and the multiple first sliding grooves are interconnected. Two first sliders are slidably connected in the first sliding grooves. Multiple first bidirectional threaded rods are rotatably connected in the multiple first sliding grooves, and the multiple first bidirectional threaded rods are fixed to each other. The first bidirectional threaded rods are threadedly connected to the corresponding two first sliders. A limit rod is rotatably connected to the first slider, and a slot is provided at one end of the limit rod.

[0017] A drive assembly, located within the base, is used to drive one of the first bidirectional threaded rods and one of the second threaded rods to rotate.

[0018] Based on the above structure, the set normal frame ensures that the user can place the wheel between two normal frames. The set first slide groove and first slider ensure that the two first sliders can slide within their corresponding first slide grooves. The set first double-threaded rod ensures that when the first double-threaded rod rotates, the two corresponding first sliders can be moved closer or further apart by the action of the first double-threaded rod's thread. The set second slide groove and second slider ensure that the two second sliders can slide within their corresponding second slide grooves. The set second threaded rod ensures that when the second threaded rod rotates, the two corresponding second sliders can be moved closer or further apart by the action of the second threaded rod's thread. The set limit rod ensures that when the first slider and... When the second slider moves, the first and second sliders can drive the corresponding limit rods to move. Through the set drive component, it is ensured that the user can drive one of the first bidirectional threaded rods and one of the second threaded rods to rotate, so that one of the first bidirectional threaded rods and one of the second threaded rods can drive multiple other first bidirectional threaded rods and multiple other second threaded rods to rotate synchronously. Through the set slot and the second slider, it is ensured that one end of the second slider can be inserted into the slot, restricting the limit rod between the first and second sliders, making it convenient for the user to open multiple limit rods and remove the wheel. Through the set fixing component, it is ensured that the user can fix one end of the limit rod on the second slider and prevent it from moving.

[0019] In the above technical solution, the fixing component further includes:

[0020] The third slide groove is formed on the inner wall of the slot. A rod is slidably connected in the third slide groove. One end of the rod passes through one end of the second slider and extends into the second slider to engage with it. The other end of the rod is fixedly connected to a spring that is fixed to the inner wall of the third slide groove. A pressing groove is formed on the rod.

[0021] The fourth slide groove is formed on the inner wall of the third slide groove and is connected to the outside. An extrusion block is slidably connected in the fourth slide groove, and one end of the extrusion block extends into the extrusion groove.

[0022] In this technical solution, the limiting rod is ensured to be fixed between the first slider and the second slider.

[0023] In the above technical solution, one end of the extrusion block is further inclined.

[0024] In this technical solution, it is ensured that when the user presses the extrusion block, and one end of the extrusion block extrudes the extrusion groove, the extrusion groove can drive the insertion rod to move.

[0025] In the above technical solution, one end of the extrusion block is further inserted into the extrusion groove.

[0026] In this technical solution, it is ensured that when the user presses the squeezing block, one end of the squeezing block can be inserted into the squeezing groove.

[0027] In the above technical solution, the driving component further includes:

[0028] The movable groove is formed inside the base and communicates with one of the first sliding grooves and one of the second sliding grooves. Two sprockets are rotatably connected inside the movable groove, and one end of each sprocket extends into one of the first sliding grooves and one of the second sliding grooves, respectively, and is fixed to one end of one of the first bidirectional threaded rods and one end of one of the second threaded rods, respectively. A chain meshes between the two sprockets.

[0029] The motor is fixedly connected to the base, and the output shaft of the motor passes through the base and extends into the movable slot to be fixed to one of the sprockets.

[0030] In this technical solution, it is ensured that wheels of any size can be placed between two normal frames.

[0031] In the above technical solution, one end of each of the two sprockets is rotatably connected to one of the first slide grooves and one of the second slide grooves, respectively, and the output shaft of the motor is rotatably connected to the base.

[0032] In this technical solution, it is ensured that when the two sprockets rotate, one end of each sprocket can rotate normally in one of the first slide grooves and one of the second slide grooves respectively, and that when the user starts the motor, the output shaft of the motor can rotate normally in the base.

[0034] In this technical solution, it is ensured that when the first bidirectional threaded rod rotates, the corresponding two first sliders will be acted upon by the two sections of threads with opposite directions on the first bidirectional threaded rod, moving away from or towards each other. Similarly, it is ensured that when the second threaded rod rotates, the two second sliders will be acted upon by the two sections of threads with opposite directions on the second threaded rod, moving away from or towards each other.

[0035] In the above technical solution, furthermore, the pitch of the first bidirectional threaded rod and the second threaded rod is the same.

[0036] In this technical solution, it is ensured that when the first bidirectional threaded rod and the second threaded rod rotate simultaneously, the corresponding two first sliders and the corresponding two second sliders will be acted upon by the threads of the first bidirectional threaded rod and the second threaded rod respectively, and move the same distance.

[0037] The beneficial effects of this utility model based on the above structure are:

[0038] 1. The auxiliary assembly device for the trolley traveling mechanism, through the setting of normal frames, ensures that the user can place the wheels between two normal frames. Through the setting of a first sliding groove and a first sliding block, it ensures that two first sliding blocks can slide within their corresponding first sliding grooves. Through the setting of a first bidirectional threaded rod, it ensures that when the first bidirectional threaded rod rotates, the corresponding two first sliding blocks can be acted upon by the thread of the first bidirectional threaded rod, moving closer or further apart. Through the setting of a second sliding groove and a second sliding block, it ensures that two second sliding blocks can slide within their corresponding second sliding grooves. Through the setting of a second threaded rod, it ensures that when the second threaded rod rotates, the corresponding two second sliding blocks can be acted upon by the thread of the second threaded rod. By moving closer or further apart, the limiting rods ensure that when the first and second sliders move, they can drive the corresponding limiting rods to move as well. The drive assembly allows the user to rotate one of the first bidirectional threaded rods and one of the second threaded rods, enabling them to drive multiple other first bidirectional threaded rods and multiple other second threaded rods to rotate synchronously. This solves the problem of traditional wheel set holders being unable to adjust due to their fixed dimensions, making them unsuitable for wheels of different thicknesses and hindering stable wheel mounting, thus affecting assembly accuracy and stability.

[0039] 2. The auxiliary assembly device of the trolley traveling mechanism, through the set slot and the second slider, ensures that one end of the second slider can be inserted into the slot, and restricts the limit rod between the first slider and the second slider, so that the user can open multiple limit rods and take out the wheel. Through the set fixing component, it is ensured that the user can fix one end of the limit rod on the second slider and make it unable to move. Attached Figure Description

A plurality of first sliding grooves 3 are provided on one side of the inner wall of the base 1, and the plurality of first sliding grooves 3 are interconnected. Two first sliders 4 are slidably connected in the first sliding grooves 3. A plurality of first bidirectional threaded rods 5 are rotatably connected in the plurality of first sliding grooves 3, and the plurality of first bidirectional threaded rods 5 are fixed to each other. The first bidirectional threaded rods 5 are threadedly connected to the corresponding two first sliders 4. A limit rod 6 is rotatably connected on the first slider 4, and a slot 7 is provided at one end of the limit rod 6.

[0055] Multiple second slide grooves 8 are formed on the other side of the inner wall of the base 1 and are connected to each other. Two second sliders 9 are slidably connected in each second slide groove 8. One end of each second slider 9 extends into the slot 7 and is inserted into the slot 7. Multiple second threaded rods 10 are rotatably connected in each of the multiple second slide grooves 8 and are fixed to each other. The second threaded rods 10 are threadedly connected to the corresponding two second sliders 9.

[0059] The third slide groove 11 is formed on the inner wall of the slot 7. A rod 12 is slidably connected in the third slide groove 11. One end of the rod 12 passes through one end of the second slider 9 and extends into the second slider 9 to engage with it. The other end of the rod 12 is fixedly connected to a spring 13 that is fixed to the inner wall of the third slide groove 11. A pressing groove 14 is formed on the rod 12.

[0060] The fourth slide 15 is formed on the inner wall of the third slide 11 and is connected to the outside. An extrusion block 16 is slidably connected in the fourth slide 15, and one end of the extrusion block 16 extends into the extrusion groove 14.

[0061] In operation, the user presses the squeezing block 16, causing one end of the squeezing block 16 to press the squeezing groove 14. This causes the squeezing groove 14 to move one end of the insert rod 12 from the second slider 9 into the third slide groove 11, compressing the spring 13. At this point, the fixing of the limiting rod 6 is released. The user then rotates the limiting rod 6, moving one end of the limiting rod 6 away from the end of the second slider 9. When the limiting rod 6 is rotated to the appropriate position, the user can place the wheel on the two normal frames 2. After placement, the user rotates the limiting rod 6 in the opposite direction. When the limiting rod 6 is rotated to the appropriate position, one end of the second slider 9 will be inserted into the slot 7. The user then releases the squeezing block 16, allowing one end of the insert rod 12 to be inserted into the end of the second slider 9 by the rebound force of the spring 13, ensuring that the limiting rod 6 can be fixed between the first slider 4 and the second slider 9.

[0067] The movable groove 17 is opened in the base 1 and is connected to one of the first sliding grooves 3 and one of the second sliding grooves 8. Two sprockets 18 are rotatably connected in the movable groove 17, and one end of the two sprockets 18 extends into one of the first sliding grooves 3 and one of the second sliding grooves 8 respectively, and is fixed to one end of one of the first bidirectional threaded rods 5 and one end of one of the second threaded rods 10 respectively. A chain 19 is engaged between the two sprockets 18.

[0068] Motor 20 is fixedly connected to base 1, and the output shaft of motor 20 passes through base 1 and extends into movable groove 17 to be fixed to one of the sprockets 18.

[0069] In operation, the user starts the motor 20, causing its output shaft to drive one of the sprockets 18 to rotate within the movable groove 17. This causes one sprocket 18 to drive another sprocket 18 via the chain 19. As both sprockets 18 rotate, they respectively drive one of the first bidirectional threaded rods 5 and one of the second threaded rods 10 to rotate. These first bidirectional threaded rods 5 and second threaded rods 10 then drive multiple other first bidirectional threaded rods 5 and multiple other second threaded rods 10 to rotate. 10 rotates within multiple first slide grooves 3 and multiple second slide grooves 8 respectively. When the first bidirectional threaded rod 5 and the second threaded rod 10 rotate, the corresponding two first sliders 4 and the corresponding two second sliders 9 will be acted upon by the threads on the first bidirectional threaded rod 5 and the second threaded rod 10 respectively, moving closer or further away from each other. When the corresponding two first sliders 4 and the corresponding two second sliders 9 approach each other to a suitable position, the corresponding two first sliders 4 and the corresponding two second sliders 9 will respectively drive the corresponding two limit rods 6 to clamp the wheel, ensuring that a wheel of any size can be placed between two normal frames 2. Example

[0070] This embodiment provides an auxiliary assembly device for a trolley traveling mechanism. In addition to the technical solution of the above embodiment, it also has the following technical features: one end of each of the two sprockets 18 is rotatably connected to one of the first slide grooves 3 and one of the second slide grooves 8, respectively, and the output shaft of the motor 20 is rotatably connected to the base 1.

[0071] Specifically, it is ensured that when the two sprockets 18 rotate, one end of each sprocket 18 can rotate normally in one of the first slide grooves 3 and one of the second slide grooves 8 respectively, and that when the user starts the motor 20, the output shaft of the motor 20 can rotate normally in the base 1. Example

[0072] This embodiment provides an auxiliary assembly device for a trolley traveling mechanism. In addition to the technical solution of the above embodiment, it also has the following technical features: the two threads on the first bidirectional threaded rod 5 have opposite directions of rotation, and the two threads on the second threaded rod 10 have opposite directions of rotation.

[0073] Specifically, when the first bidirectional threaded rod 5 rotates, the corresponding two first sliders 4 will be affected by the two sections of oppositely oriented threads on the first bidirectional threaded rod 5, causing them to move away from or towards each other. Similarly, when the second threaded rod 10 rotates, the two second sliders 9 will be affected by the two sections of oppositely oriented threads on the second threaded rod 10, causing them to move away from or towards each other. Example

[0074] This embodiment provides an auxiliary assembly device for a trolley traveling mechanism. In addition to the technical solutions of the above embodiments, it also has the following technical features: the pitch of the first bidirectional threaded rod 5 and the second threaded rod 10 is the same.

[0075] Specifically, when the first bidirectional threaded rod 5 and the second threaded rod 10 rotate simultaneously, the corresponding two first sliders 4 and the corresponding two second sliders 9 will be acted upon by the threads of the first bidirectional threaded rod 5 and the second threaded rod 10, respectively, and move the same distance.

[0076] In use, the user presses multiple compression blocks 16 by hand, causing one end of the compression block 16 to press the compression groove 14. This causes the compression groove 14 to drive one end of the insertion rod 12 from the second slider 9 into the third slide groove 11, compressing the spring 13. At this point, the fixing of the limiting rod 6 is released. The user then rotates the multiple limiting rods 6 by hand, moving one end of the limiting rod 6 away from one end of the second slider 9. When the limiting rod 6 is rotated to the appropriate position, the user can place the wheel in the appropriate position on the two normal frames 2. After placement, the user rotates the limiting rod 6 in the opposite direction. When the limiting rod 6 is rotated to the appropriate position, one end of the second slider 9 will insert into the slot 7. The user then releases the hand pressing the compression block 16, allowing one end of the insertion rod 12 to be pushed into one end of the second slider 9 by the rebound force of the spring 13, ensuring that the limiting rod 6 can be fixed between the first slider 4 and the second slider 9. At the same time, the wheel will be located between the corresponding two limiting rods 6. The user then starts the motor 20, causing the output shaft of the motor 20 to drive one of the sprockets 18 to rotate in the movable groove 17, so that one of the sprockets 18... Sprocket 18 drives another sprocket 18 to rotate via chain 19. When both sprockets 18 rotate, they will drive one of the first bidirectional threaded rods 5 and one of the second threaded rods 10 to rotate, causing one of the first bidirectional threaded rods 5 and one of the second threaded rods 10 to drive the other multiple first bidirectional threaded rods 5 and multiple multiple second threaded rods 10 to rotate. When the multiple first bidirectional threaded rods 5 and multiple second threaded rods 10 rotate in the multiple first sliding grooves 3 and multiple second sliding grooves 8, the corresponding two first sliders 4 and the corresponding two second sliders 9 will be acted upon by the threads on the first bidirectional threaded rods 5 and the second threaded rods 10, moving closer or further away from each other. When the corresponding two first sliders 4 and the corresponding two second sliders 9 approach each other to a suitable position, they will drive the corresponding two limiting rods 6 to clamp the wheel, ensuring that a wheel of any size can be placed between the two normal frames 2.
