Description

Technical Field

[0001] This utility model relates to the field of differential assembly line technology, specifically a convenient differential assembly line tray. Background Technology

[0002] The differential is a key component of the transmission system in automobiles and other vehicles, mainly composed of a differential housing, planetary gears, and half-shaft gears. Its core function is to allow the left and right wheels to rotate at different speeds when the vehicle is turning or driving on uneven surfaces, achieving pure rolling without slippage, and also to rationally distribute torque. During operation, the planetary gears only revolve around the central axis when driving straight, and rotate on their own axes when turning to adjust the speed of the left and right wheels. Differentials are categorized by function (e.g., inter-wheel, inter-shaft) and by working characteristics (e.g., ordinary, anti-slip). They are widely used in various vehicle types, including passenger cars, SUVs, and commercial vehicles. Passenger cars emphasize handling, SUVs and off-road vehicles prioritize off-road capability, and commercial vehicles emphasize stable and safe transportation; differentials are an indispensable component for ensuring vehicle performance and stability.

[0003] Differential assembly line pallets are specialized tooling equipment used in automotive manufacturing to carry, transport, and position differential components. Their core function is to ensure the efficiency and precision of the assembly process. Pallets are typically made of high-strength engineering plastics, aluminum alloys, or steel, with a surface designed with an anti-slip coating or positioning grooves. They work in conjunction with mechanical clamps, magnetic adsorption, or sensors to achieve precise component positioning. Guiding mechanisms work in conjunction with the production line tracks to guide the pallet's movement. Some pallets integrate electric or pneumatic drive modules to achieve automated conveying.

[0004] Regarding the existing related technologies, the inventors believe that the following defects exist: the existing differential assembly line trays can only meet the assembly of one type of differential, and the production process requires the customization of corresponding trays for different differentials, which results in a waste of resources. Utility Model Content

[0005] To address the technical problem of resource waste caused by the need to customize pallets for different differentials in existing production processes, this utility model provides a convenient differential assembly line pallet.

[0006] This utility model is achieved using the following technical solution: a convenient differential assembly line tray, comprising a tray body and a clamping plate. A handwheel is provided at one end of the tray body, and a connecting shaft is fixedly connected to one end of the handwheel. A first rotating shaft is provided at one end of the connecting shaft, and a first bevel gear is fixedly connected to one end of the first rotating shaft. Two second bevel gears are meshed at both ends of the first bevel gear, and a third bevel gear is meshed at one end of each of the second and third bevel gears. A second rotating shaft is fixedly connected to one side of each of the second and third bevel gears. A movable seat is threaded onto the external surfaces of the first and second rotating shafts. The top of the movable seat is fixedly connected to the bottom of the clamping plate. The clamping plate is movably connected to the top of the tray body. Multiple movable grooves are machined inside the tray body, and the movable seat is movably connected to the inside of these grooves.

[0007] Preferably, the movable seat has sliders fixedly connected to both ends, the movable groove has grooves machined on both sides, and the sliders are movably connected inside the grooves.

[0008] Preferably, the first rotating shaft has a movable inner cavity machined inside, and one end of the connecting shaft is movably connected to the inside of the movable inner cavity.

[0009] Preferably, a return spring is provided inside the movable inner cavity, one end of the return spring is fixedly connected to one end of the connecting shaft, and the other end of the return spring is fixedly connected to the inner wall of one end of the movable inner cavity.

[0010] Preferably, one end of the connecting shaft is fixedly connected to two limiting blocks, and limiting grooves are machined on both sides of the movable inner cavity, with the limiting blocks movably connected inside the limiting grooves.

[0011] Preferably, a fixing ring is fixedly connected to one side of the handwheel, and a limiting ring groove is machined at one end of the tray body, with the fixing ring being plugged into the inside of the limiting ring groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In use, this utility model involves first pulling the handwheel outward to disengage the fixed insert ring from the limiting ring groove, then rotating the handwheel. The handwheel drives the connecting shaft to rotate, which in turn drives the first rotating shaft, the first bevel gear, the second bevel gear, the third bevel gear, and the second rotating shaft to rotate. The rotation of the first and second rotating shafts moves the movable seat, which in turn moves the four clamping plates closer or further apart, thereby adjusting the assembly line tray. The operation is convenient and simple. Attached Figure Description

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Example 1: Please refer to Figure 1 - Figure 3 This embodiment provides a convenient differential assembly line tray, including a tray body 1 and a clamping plate 2. One end of the tray body 1 is provided with a handwheel 3, and one end of the handwheel 3 is fixedly connected to a connecting shaft 4. One end of the connecting shaft 4 is provided with a first rotating shaft 5, and one end of the first rotating shaft 5 is fixedly connected to a first bevel gear 6. The two ends of the first bevel gear 6 are meshed with two second bevel gears 7, and one end of the second bevel gear 7 is meshed with a third bevel gear 8. One side of the second bevel gear 7 and the third bevel gear 8 is fixedly connected to a second rotating shaft 9. The first rotating shaft 5 and the second rotating shaft 9 are externally threaded with a movable seat 10. The top of the movable seat 10 is fixedly connected to the bottom of the clamping plate 2, and the clamping plate 2 is movably connected to the top of the tray body 1.

[0020] When it is necessary to adjust the assembly line tray to correspond to different models of differentials, turn the handwheel 3. The handwheel 3 will drive the connecting shaft 4 to rotate. The connecting shaft 4 will drive the first rotating shaft 5 to rotate through the limit block 16. The first rotating shaft 5 will drive the first bevel gear 6 to rotate. The first bevel gear 6 will drive the two second bevel gears 7 to rotate. The second bevel gears 7 will drive the third bevel gear 8 to rotate. The second bevel gears 7 and the third bevel gear 8 will drive the second rotating shaft 9 to rotate. The rotation of the first rotating shaft 5 and the second rotating shaft 9 will move the movable seat 10. The movable seat 10 will drive the four clamping plates 2 to move closer or further away from each other synchronously, thereby adjusting the assembly line tray to correspond to different models of differentials. It is convenient and simple to use.

[0021] Furthermore, the pallet body 1 has multiple movable slots 11 machined inside, and the movable seat 10 is movably connected inside the movable slot 11. When the movable seat 10 moves, the movable seat 10 will move along the inside of the movable slot 11, and the movable slot 11 will limit the movement of the movable seat 10.

[0022] Furthermore, the movable seat 10 is fixedly connected to both ends of the slider 12, and the movable groove 11 is machined with sliding grooves 13 on both sides. The slider 12 is movably connected inside the sliding groove 13. When the movable seat 10 moves to the point where the slider 12 moves, the slider 12 will move along the inside of the sliding groove 13. The sliding groove 13 will limit the movement of the slider 12, so that the movable seat 10 and the clamping plate 2 remain stable when they move.

[0023] Furthermore, the first rotating shaft 5 has a movable inner cavity 14 machined inside, one end of the connecting shaft 4 is movably connected to the inside of the movable inner cavity 14, and a return spring 15 is provided inside the movable inner cavity 14. One end of the return spring 15 is fixedly connected to one end of the connecting shaft 4, and the other end of the return spring 15 is fixedly connected to the inner wall of one end of the movable inner cavity 14.

[0024] When it is necessary to rotate the handwheel 3, pull the handwheel 3 outward. The handwheel 3 will drive the connecting shaft 4 to move outward. The connecting shaft 4 will move outward along the inside of the movable inner cavity 14. At the same time, the connecting shaft 4 will pull the return spring 15 to extend. With the return spring 15 provided, when the handwheel 3 is pulled, the connecting shaft 4 will drive the return spring 15 to extend. When the handwheel 3 is released, the return spring 15 will retract and return to its original position. The return spring 15 will drive the connecting shaft 4 and the handwheel 3 to move back to their original positions.

[0025] Furthermore, one end of the connecting shaft 4 is fixedly connected to two limiting blocks 16, and the two sides of the movable inner cavity 14 are machined with limiting grooves 17. The limiting blocks 16 are movably connected inside the limiting grooves 17. When the handwheel 3 pulls the connecting shaft 4, the connecting shaft 4 will drive the limiting blocks 16 to move along the inside of the limiting grooves 17. The limiting grooves 17 will limit the movement of the limiting blocks 16. At the same time, when the handwheel 3 rotates, the connecting shaft 4 will drive the first rotating shaft 5 to rotate through the limiting blocks 16.

[0026] Furthermore, a fixed insert ring 18 is fixedly connected to one side of the handwheel 3, and a limiting ring groove 19 is machined at one end of the tray body 1. The fixed insert ring 18 is plugged into the inside of the limiting ring groove 19. When the handwheel 3 is released, the return spring 15 returns to its original position and retracts. The return spring 15 will drive the connecting shaft 4 and the handwheel 3 to move. The handwheel 3 will drive the fixed insert ring 18 to move and insert into the inside of the limiting ring groove 19. The fixed insert ring 18 limits the handwheel 3 and prevents the handwheel 3 from moving.

[0027] Working principle: By first pulling the handwheel 3 outward, the fixed insert ring 18 is disengaged from the inside of the limiting ring groove 19. Then, the handwheel 3 is rotated, which drives the connecting shaft 4 to rotate. The connecting shaft 4 drives the first rotating shaft 5 to rotate through the limiting block 16. The first rotating shaft 5 drives the first bevel gear 6 to rotate. The first bevel gear 6 drives the two second bevel gears 7 to rotate. The second bevel gears 7 drive the third bevel gear 8 to rotate. The second bevel gears 7 and the third bevel gear 8 drive the second rotating shaft 9 to rotate. The rotation of the first rotating shaft 5 and the second rotating shaft 9 moves the movable seat 10. The movable seat 10 drives the four clamping plates 2 to move closer or further apart synchronously, thereby adjusting the assembly line tray to accommodate different models of differentials. The operation is convenient and simple.
