Description

Technical Field

[0001] This application relates to the field of automobile production lines, and more particularly to a lifting mechanism for an automobile production line. Background Technology

[0002] With the development of automobiles, car appearances have become increasingly diverse. On automobile production lines, it is often necessary to lift the chassis (such as side panels) to meet the needs of various processing steps and transportation.

[0003] For example, Chinese patent CN120170351A discloses an automotive welding conveyor line with a lifting mechanism, which includes a welding table, a conveyor rail, a horizontal conveyor mechanism, a fixing mechanism, and a frame lifting mechanism. This application utilizes the fixing mechanism to fix the frame to be processed onto the welding table for welding. Then, through the cooperation of the lifting mechanism, the horizontal conveyor mechanism, and the conveyor rail, the processed frame is conveyed to the next process. The frame lifting mechanism includes a lifting cylinder, a lifting plate, and a fitting frame. The fitting frame is mounted on the lifting plate and can adapt to the irregular structure of the lifting part of the automotive frame, allowing the frame and the fitting frame to fit tightly together. The lifting cylinder moves the fitting frame together with the frame, further reducing the possibility of displacement during the frame lifting process and improving the stability of the lifting process.

[0004] However, in actual production and processing, different models of bicycle frames have different shapes, requiring different fitting frames to fit them. This means that different fitting frames need to be replaced when lifting different frames, resulting in poor applicability. Therefore, a lifting mechanism is needed to improve the stability and applicability of the frame lifting process. Summary of the Invention

[0005] To improve the stability and applicability of the vehicle frame lifting process, this application provides a lifting mechanism for an automobile production line.

[0006] This application provides a lifting mechanism for an automobile production line, which adopts the following technical solution:

[0007] A lifting mechanism for an automobile production line includes a base, a movable seat, a lifting component, and a stabilizing component; The lifting assembly is mounted on the base, and the movable seat is slidably mounted on the lifting assembly. The lifting assembly is used to lift the movable seat, and the movable seat is used to place the vehicle frame. The stabilizing component includes a stabilizing drive, a pushing component, and a limiting component; The stabilizing drive component is disposed on the base, and the pushing component is disposed on the stabilizing drive component; The limiting component includes a limiting post and a limiting seat, and multiple limiting components are provided; the limiting seat is disposed on the pushing component, and the limiting post is slidably disposed on the limiting seat; the pushing component is used to drive the limiting post to move on the limiting seat; The stabilizing drive component drives the limiting component to move, causing the frame to push the limiting post to move on the limiting seat, thus embedding the frame into the limiting component.

[0008] By adopting the above technical solution, when the frame needs to be lifted, the stabilizing drive component drives the limiting component to move until it abuts against the frame. After the frame contacts the limiting component, the frame pushes the contacting limiting post, thereby embedding the frame into the limiting component. By using multiple limiting posts that slide on the limiting seat, frames of different shapes can be embedded into the limiting component, thus improving the applicability of the lifting mechanism of this application. After the frame is embedded into the limiting component, the limiting component can support the frame, thereby further improving the stability of the frame during the lifting process of the lifting assembly.

[0009] Optionally, the lifting assembly includes a lifting drive and a lifting frame; the lifting drive is disposed on the base and connected to the lifting frame, and the movable seat is slidably disposed on the lifting frame; the lifting drive is used to drive the lifting frame to move in the vertical direction.

[0010] By adopting the above technical solution, the lifting drive component lifts the lifting frame, thereby achieving the lifting of the vehicle frame.

[0011] Optionally, a locking assembly is also included, comprising a locking drive, a locking support, a locking plate, and a locking block; the locking support is disposed on the lifting frame, the locking drive is rotatably disposed on the locking support, the locking plate is rotatably disposed on the locking support, and the locking block is disposed on the lifting frame; the locking plate is rotatably connected to the drive; the drive drives the locking plate to rotate on the locking support, causing the locking plate to insert into the locking block.

[0012] By adopting the above technical solution, when the moving seat transports the frame to be processed to the position of the lifting mechanism, the locking drive drives the locking plate to rotate on the locking support, so that the locking plate can be inserted into the locking block on the support, thereby restricting the movement of the support and improving the stability of the frame during processing and lifting.

[0013] Optionally, the lifting assembly further includes a guide rod disposed on the base, and the lifting frame is slidably connected to the guide rod.

[0014] By adopting the above technical solution, the guide rod can limit the movement direction of the lifting frame, thereby improving the stability of the lifting frame during movement.

[0015] Optionally, the movable seat is provided with a support seat, and the vehicle frame is placed on the support seat.

[0016] By adopting the above technical solution, the support can support the frame, allowing the frame to move with the moving seat.

[0017] Optionally, the pushing component includes an air supply pipe, a connecting seat, a solenoid valve, and an exhaust component; the connecting seat is disposed on the stabilizing driving component, the connecting seat is connected to the limiting seat, the air supply pipe is connected to the connecting seat, the solenoid valve is disposed on the air supply pipe, and the solenoid valve is used to control the air flow in the air supply pipe. The air supply pipe is vented, allowing the limiting post to slide on the limiting seat; After the solenoid valve is closed, the frame pushes the limiting post to move and exhausts air through the exhaust component, so that the frame is embedded in the limiting component.

[0018] By adopting the above technical solution, when the limiting component needs to support the vehicle frame, since the connecting seat and the limiting seat are connected, the limiting post is slidably mounted on the limiting seat. After the air supply pipe passes through the connecting seat, the limiting post moves away from the connecting seat. After the limiting post moves a specified distance, the solenoid valve closes, and under the action of the air pressure in the connecting seat, the position of each limiting post remains unchanged.

[0019] At this point, the stabilizing drive component moves the limiting component to contact the frame, and the frame pushes the contacting limiting post towards the connecting seat. During the movement of the limiting post, the gas inside the connecting seat is discharged from the exhaust pipe after passing through a one-way valve, thus allowing the frame to be embedded into the limiting component. Through the cooperation of the exhaust component, the connecting seat, and the solenoid valve, the limiting component can adaptively form the shape of the frame, improving the applicability of this application.

[0020] Optionally, the stabilizing component further includes a stabilizing element, which includes an elastic element and a limiting block. The limiting block is disposed on the limiting post, and the elastic element is disposed between the limiting block and the limiting seat. The limiting post is provided with a vent hole; the frame pushes the limiting post to move closer to the limiting seat, so that the vent hole communicates with the connecting seat.

[0021] By adopting the above technical solution, when the frame needs to be processed, after the frame is fixed, the stabilizing drive component drives the limiting component to move, so that the frame contacts the limiting post. At this time, the frame pushes the contacting limiting post to move closer to the connecting seat, causing the corresponding elastic component to compress. The elastic component can buffer the contact between the limiting post and the frame. At the same time, the vent moves to connect with the connecting seat.

[0022] After the vent is connected to the connecting seat, the air supply pipe draws in air, which allows the end of the limiting post that abuts against the frame to hold the frame in place, thereby further limiting the stability of the frame during processing.

[0023] Optionally, the limiting post includes a post body and a suction cup, the suction cup is disposed on the post body, the post body is in communication with the suction cup, and the suction cup abuts against the vehicle frame.

[0024] By adopting the above technical solution, the suction cup can increase the adsorption area and improve the reliability of the limiting post in adhering to the frame.

[0025] Optionally, the limiting post further includes a ball head, the post body is rotatably connected to the ball head, the suction cup is connected to the ball head, and the ball head is connected to both the suction cup and the limiting post.

[0026] By adopting the above technical solution, the suction cup and the limiting post are connected by a ball head, which allows the suction cup to adaptively conform to the surface of the frame.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By incorporating a stabilizing component, when the chassis needs to be lifted, the stabilizing drive unit drives the limiting component to move until it abuts against the chassis. After the chassis contacts the limiting component, the chassis pushes the contacting limiting post, thereby embedding the chassis into the limiting component. By using multiple limiting posts that slide on the limiting seat, chassis of different shapes can be embedded into the limiting component, thus improving the applicability of the lifting mechanism of this application. After the chassis is embedded into the limiting component, the limiting component can support the chassis, thereby further improving the stability of the chassis during the lifting process of the lifting component.

[0029] 2. By setting a locking component, when the moving seat transports the frame to be processed to the position of the lifting mechanism, the locking drive drives the locking plate to rotate on the locking support, so that the locking plate can be inserted into the locking block on the support, thereby restricting the movement of the support and improving the stability of the frame during processing and lifting.

[0030] 3. By incorporating a pushing component, when the limiting component needs to support the frame, the limiting post slides on the limiting seat due to the connection between the connecting seat and the limiting seat. After air is supplied through the air pipe into the connecting seat, the limiting post moves away from the connecting seat. After the limiting post moves a specified distance, the solenoid valve closes, and the position of each limiting post remains unchanged under the pressure of the air in the connecting seat. At this time, the stabilizing drive component drives the limiting component to move until it abuts against the frame, and the frame pushes the contacting limiting post towards the connecting seat. During the movement of the limiting post, the gas in the connecting seat is discharged through the exhaust pipe after passing through the one-way valve, thus embedding the frame into the limiting component. Through the cooperation of the exhaust component, the connecting seat, and the solenoid valve, the limiting component can adaptively form the shape of the frame, improving the applicability of this application.

[0041] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0042] This application discloses a lifting mechanism for an automobile production line, such as... Figure 1 As shown, the lifting mechanism includes a base 1, a movable seat 2, a lifting component 3, a stabilizing component 4, and a locking component 5.

[0043] Specifically, such as Figure 1 and Figure 2 As shown, the lifting assembly 3 includes a lifting drive component 31, a lifting frame 32, and a guide rod 33. The body of the lifting drive component 31 is fixedly connected to the base 1, and the output end of the lifting drive component 31 is fixedly connected to the lifting frame 32. Preferably, the lifting drive component 31 is a pneumatic push rod. The guide rod 33 is fixedly installed on the base 1, and the lifting frame 32 is slidably connected to the guide rod 33. The guide rod 33 can limit the movement direction of the lifting frame 32, thereby improving the lifting stability of the lifting frame 32. In this embodiment, a roller assembly 9 is fixedly connected to the lifting frame 32, and the movable seat 2 can move on the lifting frame 32 through the roller assembly 9. A support seat 6 is fixedly connected to the movable seat 2, which can support the vehicle frame and allow the vehicle frame to move with the movable seat 2.

[0044] like Figure 2 and Figure 3As shown, the locking assembly 5 includes a locking drive 51, a locking support 52, a locking plate 53, and a locking block 54. Specifically, the locking support 52 is fixedly connected to the lifting frame 32, the body of the locking drive 51 is rotatably connected to the locking support 52, the output end of the locking drive 51 is rotatably connected to the locking plate 53, the locking plate 53 is rotatably connected to the locking support 52, and the locking block 54 is fixedly mounted on the movable seat 2. When the movable seat 2 moves to the designated position of the lifting mechanism, the output end of the locking drive 51 moves, allowing the locking plate 53 to rotate on the locking support 52 and thus insert into the locking block 54. After the locking plate 53 is inserted into the locking block 54, the movement of the movable seat 2 can be restricted, reducing the possibility of the frame moving during processing. In addition, after the frame is placed on the support 6 and the locking plate 53 is inserted into the locking block 54, the fixing mechanism (not shown in the figure) mounted on the base 1 fixes the frame, thereby reducing the possibility of the frame moving during processing and improving processing accuracy. After processing is completed, the fixing mechanism releases its hold on the frame, allowing the frame to be lifted. Furthermore, in this embodiment, when the frame needs to be processed at different heights, corresponding fixing mechanisms are provided at each height to secure the frame.

[0045] like Figure 4 , Figure 5 and Figure 6 As shown, the stabilizing component 4 includes a stabilizing drive 41, a pushing component 42, a limiting component 43, and a stabilizing component 44. The pushing component 42 includes an air supply pipe 421, a connecting seat 422, a solenoid valve 423, and an exhaust component 424, wherein the exhaust component 424 includes an exhaust pipe 4241 and a one-way valve 4242. The limiting component 43 includes a limiting post 431 and a limiting seat 432, and the stabilizing component 44 includes an elastic component 441 and a limiting block 442. In this embodiment, the limiting post 431 is hollow inside.

[0046] Specifically, such as Figure 4 As shown, the body of the stabilizing drive unit 41 is fixedly mounted on the base 1, and the output end of the stabilizing drive unit 41 is fixedly connected to the connecting seat 422. In this embodiment, the stabilizing drive unit 41 is a two-axis linear module. The stabilizing drive unit 41 can drive the connecting seat 422 to move in the vertical and horizontal directions. When the connecting seat 422 moves in the vertical direction, it can realize the lifting of the frame. When the connecting seat 422 moves in the horizontal direction, it can flexibly adjust the position of the limiting member 43 according to different frame shapes.

[0047] like Figure 4 and Figure 5As shown, multiple limiting members 43 are fixedly installed on the connecting seat 422. Each limiting member 43 has a limiting seat 432 fixedly installed on the connecting seat 422, and the limiting seat 432 communicates with the connecting seat 422. A limiting post 431 is slidably installed on the limiting seat 432. An elastic member 441 is placed inside the limiting seat 432, and one end of the elastic member 441 is fixedly connected to the inner wall of the limiting seat 432 on the side closest to the connecting seat 422.

[0048] In addition, such as Figure 6 and Figure 7 As shown, the limiting post 431 includes a post body 4311, a ball head 4312, and a suction cup 4313. The post body 4311 has a hollow structure and a vent hole 7 is provided on the post body 4311, which communicates with the interior of the post body 4311. The ball head 4312 is embedded in one end of the post body 4311 and can rotate on the post body 4311. The suction cup 4313 is fixedly connected to the ball head 4312. The suction cup 4313 is made of elastic material. A limiting block 442 is fixedly connected to the post body 4311. A sealing block 8 is fixedly connected inside the limiting seat 432, and an elastic element 441 is sleeved on the outside of the sealing block 8. In the natural state, the limiting block 442 abuts against one end of the elastic element 441. At this time, the vent hole 7 is located inside the limiting seat 432, and the sealing block 8 can block the vent hole 7. The sealing block 8 has a movable groove 81, and the limiting block 442 can move within the movable groove 81.

[0049] like Figure 5 As shown, an air supply pipe 421 is connected to the connecting seat 422, and the air supply pipe 421 is connected to an air source. A solenoid valve 423 is installed on the air supply pipe 421, which can control the flow of air in the air supply pipe 421. An exhaust pipe 4241 is also connected to the connecting seat 422, and a one-way valve 4242 is installed on the exhaust pipe 4241.

[0050] It should be noted that when the frame needs to be processed, the fixing mechanism first fixes the frame, and then the stabilizing drive component 41 lifts the connecting seat 422 to move, causing the limiting post 431 to abut against the frame. As the connecting seat 422 abuts against the frame and continues to move, the frame pushes the limiting post 431 within the limiting seat 432. At this time, the limiting block 442 compresses the elastic element 441. Under the elastic force of the elastic element 441, the suction cup 4313 can abut against the surface of the frame. Simultaneously, as the limiting post 431 moves closer to the connecting seat 422, the vent 7 enters the connecting seat 422, making the connecting seat 422 connected to the limiting post 431. After the connecting seat 422 and the limiting post 431 are connected, air is drawn into the air supply pipe 421, allowing the suction cup 4313 to adhere to the frame, thereby further improving the restriction on frame displacement and thus improving the stability during frame processing.

[0051] After the frame is machined, the air supply pipe 421 blows air to detach the suction cup 4313 from the frame. At the same time, the stabilizing drive component 41 drives the connecting seat 422 to move away from the frame. After the connecting seat 422 moves a specified distance, under the action of the elastic force of the elastic component 441, the limiting post 431 connected to the connecting seat 422 moves towards the limiting seat 432 until the elastic component 441 returns to its natural state.

[0052] When the chassis needs to be raised, the air supply pipe 421 delivers a specified airflow into the connecting seat 422, causing all the limiting posts 431 to move to the top of the limiting seat 432 and the limiting block 442 to move to abut against the top wall of the moving groove 81. At this time, the limiting block 442 disengages from the elastic member 441. Then, the control solenoid valve 423 closes, so that the air pressure in the connecting seat 422 remains constant.

[0053] After the solenoid valve 423 closes, the stabilizing drive 41 drives the connecting seat 422 to move closer to the frame and abut against the frame, causing the frame to move the contacting limit post 431 closer to the connecting seat 422. During the movement of the limit post 431, the one-way valve 4242 detects that the air pressure in the connecting seat 422 has reached a set value, allowing the gas in the connecting seat 422 to be discharged through the one-way valve 4242 and the exhaust pipe 4241, thereby allowing the limit member 43 to adaptively form the shape of the frame, and then embed the frame into the limit member 43. After the stabilizing drive 41 drives the connecting seat 422 to move a specified distance, causing the frame to stop moving after embedding, the one-way valve 4242 closes, allowing the limit member 43 to support the frame.

[0054] This application allows air to circulate within the connecting seat 422, enabling the limiting member 43 to adaptively shape the frame after contact with it, thus making it suitable for frames of different shapes and improving the applicability of the lifting mechanism. The stabilizing component 4 further supports and limits the frame after it is released from the fixing mechanism, improving the stability of the frame lifting process.

[0055] The implementation principle of a lifting mechanism for an automobile production line according to an embodiment of this application is as follows:

[0056] After the frame is positioned at the designated location by the lifting mechanism, the fixing mechanism first secures the frame for processing. Specifically, after the fixing mechanism secures the frame, the stabilizing drive 41 drives the connecting seat 422 closer to the frame. After the limiting post 431 abuts against the frame, as the connecting seat 422 continues to move a specified distance, the frame pushes the contacting limiting post 431 until it connects with the connecting seat 422. At this point, the suction cup 4313 abuts against the frame surface. Then, the air supply pipe 421 draws in air, and the suction further secures the frame, reducing the possibility of frame movement during processing.

[0057] When the frame needs to be lifted after processing, the stabilizing drive 41 drives the connecting seat 422 away from the frame. Under the elastic force of the elastic element 441, the limiting post 431 returns to the limiting seat 432. At this time, the air supply pipe 421 supplies air into the connecting seat 422. When the specified airflow causes the limiting post 431 to move away from the connecting seat 422 to a specified position, the solenoid valve 423 closes, keeping the limiting post 431 in a fixed position under the action of air pressure. Then, the one-way valve 4242 is opened, and the stabilizing drive 41 drives the connecting seat 422 closer to the frame. Under the push of the frame, in conjunction with the exhaust pipe 4241 and the one-way valve 4242, the frame can push the abutting limiting post 431 to move. After the stabilizing drive 41 moves a specified distance, it stops. At this time, the one-way valve 4242 closes the passage of the exhaust pipe 4241, keeping the limiting post 431 in a fixed position under the action of air pressure. Finally, the fixing mechanism releases its fixation on the frame, and with the cooperation of the lifting drive component 31 and the stabilizing drive component 41, the limiting component 43 and the support seat 6 lift the frame to the specified height, completing the lifting operation.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
