Technical Field

[0001] The invention relates to the technical field of vehicle frame side jacking equipment, in particular to a traveling side jacking mechanism for an automobile assembly workshop. Background Art

[0002] The side lifter is a mechanical automated conveying device, which is mainly used to lift the car body from a low position to a high position and maintain the balance of the car body. It plays an important role in the automobile logistics system. The side lifter is usually used in automobile welding workshops, and is used in conjunction with a forklift transfer machine at the transfer station of the body storage line to transfer the car body from one conveyor line to another. Specifically, the working principle of the accompanying side lifter is to run synchronously with the ground panel conveyor. It picks up the car body from the support of the ground panel conveyor and then transfers it to the aerial conveyor, thereby realizing a smooth transfer of the car body from the ground panel conveyor to the aerial conveyor.

[0003] Most of the existing accompanying side-lift mechanisms used in automobile assembly workshops lift the frame from the bottom until the frame is moved to a specified height. Most of the lifting parts in the accompanying side-lift mechanisms have uniform specifications. If you want to lift a frame with a longer body, the lifting parts cannot be adjusted. When lifting a frame with a longer body, the balance of the frame is difficult to ensure and it is easy to shake, which affects the stability and safety of the frame during the transfer operation and the accuracy of the fork transplanter when docking with the frame.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1: Reference Figure 1-3 The accompanying side lifting mechanism for automobile assembly workshop shown in the figure comprises two sets of accompanying frames 1 which can move synchronously and a lifting seat 10 arranged on the accompanying frames 1. Both sets of lifting seats 10 are provided with docking arms 12 which can move toward the frame direction and cylinders 11 which can control the movement of the docking arms 12.

[0030] like Figure 4-6 As shown, the docking arms 12 are provided with guide rods 13 and support bars 14 which are distributed in parallel, the support bars 14 are provided with a first bracket block 15 and a second bracket block 16 which can move along the distribution direction of the support bars 14, a plurality of follower brackets 22 with adjustable spacing are provided in the relative space between the first bracket block 15 and the second bracket block 16, and as the lifting seat 10 rises, the first bracket block 15, the second bracket block 16 and the follower bracket 22 located under the frame can lift it from the bottom of the frame.

[0031] If the frame is replaced and a longer frame needs to be lifted, the second support block 16 can move along the distribution direction of the support bar 14, and the multiple follower supports 22 also adjust the spacing accordingly. The first support block 15, the second support block 16 and the multiple follower supports 22 after the movement are located at the bottom of the frame to form a larger lifting contact surface, which is suitable for a longer frame. Therefore, based on the different lengths of the frame body, the first support block 15, the second support block 16 and the multiple follower supports 22 can be adjusted to avoid the front and rear shaking of the frame during the movement, and improve the stability of the frame during the lifting process.

[0032] like Figure 4-6 As shown, the guide rod 13 is provided with a pair of limiting side columns 21 whose spacing can be adjusted as the second bracket 16 moves. When the docking arm 12 moves toward the frame, the pair of limiting side columns 21 approach the side of the frame until the docking arm 12 moves to the specified position, at which time the limiting side columns 21 abut against the frame to position it.

[0033] When the first bracket 15, the second bracket 16 and the follower bracket 22 lift the frame from the bottom, the setting of the limiting side column 21 can further prevent the left and right deviation of the vehicle body during the movement, further ensure the stability of the frame during the lifting process, and ensure the accuracy of the transplanting elevator and the frame during the docking process. In addition, when the second bracket 16 adjusts the distance with the first bracket 15 to adapt to frames of different body lengths, the limiting side column 21 can also make adaptive adjustments, and can comprehensively and stably position and connect the sides of the frames of different body lengths.

[0034] Specifically, Figure 1-3 As shown, two groups of accompanying frames 1 are connected through a walking base 2, and an accompanying base 3 is provided below the walking base 2. A chain conveyor 4 and a linear guide 5 are provided on both sides of the accompanying base 3. One end of the walking base 2 is connected to the chain conveyor 4, and the other end is provided on the linear guide 5. With the operation of the chain conveyor 4, the walking base 2 can move along the distribution path of the linear guide 5 until it reaches different workstations.

[0035] One side of one of the traveling frames 1 is provided with two sets of synchronously rotatable electric reels 6, and the electric reels 6 are provided with lifting chains 7 that can be wound thereon, the traveling frame 1 close to the electric reels 6 is provided with a first limiting wheel 8, and the traveling frame 1 far from the electric reels 6 is provided with upper and lower sets of second limiting wheels 9, and the two lifting chains 7 pass through the first limiting wheel 8 and the upper and lower sets of second limiting wheels 9 respectively and are connected to a lifting seat 10. Therefore, when the electric reels 6 rotate, the two lifting chains 7 can move accordingly to lift the two sets of lifting seats 10.

[0036] In order to maintain the stability of the lifting seat 10 during movement, a roller crawling frame is provided on the lifting seat 10, and a vertical guide rail for the roller crawling frame to move is provided on the accompanying frame 1. When the two lifting chains 7 synchronously lift the two groups of lifting seats 10, the roller crawling frame slides synchronously on the vertical guide rail.

[0037] like Figure 7-9 As shown, the bottom end of the second bracket 16 is provided with a follower sleeve 17 that can move synchronously with it, and a slidable traction block 18 is provided in the follower sleeve 17. The bottom end of the traction block 18 is connected to a driving arm 19 through a bearing, and the other end of the driving arm 19 is connected to a motor 20. The driving arm 19 and the motor 20 are both arranged below the docking arm 12. When the distance between the second bracket 16 and the first bracket 15 needs to be adaptively adjusted according to the actual body length of the frame, the motor 20 can be controlled by the control system to drive the driving arm 19 to rotate. With the rotation of the driving arm 19, the traction block 18 slides to different positions in the follower sleeve 17 to drive the follower sleeve 17 and the second bracket 16 to move along the distribution direction of the support bar 14. After the distance between the second bracket 16 and the first bracket 15 is expanded, the frame of different body lengths can be lifted.

[0038] A first guide sleeve 131 and a movable second guide sleeve 132 are provided on the guide rod 13, and a pair of limiting side columns 21 are respectively provided on the first guide sleeve 131 and the second guide sleeve 132. The first guide sleeve 131 and the second guide sleeve 132 are connected by a reset spring 133, and the second guide sleeve 132 is connected to the follower sleeve 17. When the follower sleeve 17 moves along the distribution direction of the support bar 14, the second guide sleeve 132 and the limiting side column 21 connected thereto move synchronously.

[0039] The second guide sleeve 132 equipped with the limiting side column 21 can make adaptive adjustments according to the displacement of the follower sleeve 17, so that the limiting side column 21 always moves synchronously with the second bracket block 16, which is suitable for a frame with a longer body, so that the first bracket block 15 and the second bracket block 16 located at the bottom of the frame and a pair of limiting side columns 21 located on the side of the frame are symmetrically and evenly distributed. In the process of lifting the frame, the frames of different body lengths can be comprehensively and stably positioned and connected, ensuring the stability of the frame during the lifting process.

[0040] Embodiment 2: On the basis of Embodiment 1, in order to enable the multiple follower supports 22 to adjust the spacing as the second support block 16 moves, the follower supports 22 located at the head and tail ends of the multiple follower supports 22 are respectively connected to the first support block 15 and the second support block 16, and two adjacent follower supports 22 are connected by an elastic structure. In order to maintain the linearity of the follower supports 22 during movement, a slider is provided on the follower supports 22, and a support rail 151 for the slider to move is provided on the first support block 15. When the spacing between the first support block 15 and the second support block 16 changes, the follower supports 22 and the slider can move along the distribution direction of the support rail 151.

[0041] The elastic structure includes a connecting rod 23 spanning the gap between two adjacent follower supports 22, a pressure spring 24 coaxially arranged on the connecting rod 23, a fixed sleeve 25 and a movable sleeve 26 respectively arranged at both ends of the pressure spring 24, the fixed sleeve 25 and the movable sleeve 26 are respectively arranged at the bottom ends of the two follower supports 22 adjacent to the connecting rod 23, and the fixed sleeve 25 is fixed to the end of the connecting rod 23. Therefore, except for the follower supports 22 at the head and tail ends, the bottom ends of the remaining follower supports 22 are each provided with a fixed sleeve 25 and a movable sleeve 26.

[0042] When the second bracket 16 and the follower bracket 22 connected thereto move toward the first bracket 15, the movable sleeve 26 squeezes the pressure spring 24, and when the pressure spring 24 contracts to a certain extent, the fixed sleeve 25 at the other end of the pressure spring 24 moves accordingly. Since the remaining follower brackets 22 are not only connected to the fixed sleeve 25, but also connected to the movable sleeve 26 in another elastic structure, under the continuous distribution of multiple elastic structures, the movable sleeves 26 located under the multiple follower brackets 22 successively contract the pressure springs 24 until the spacing between the multiple follower brackets 22 is successively reduced, so that the follower brackets 22 are in a tightened state.

[0043] If it is necessary to lift a vehicle frame with a longer body, as the second support block 16 moves, under the elastic potential energy of the pressure spring 24 in the multiple elastic structures, the multiple elastic structures and the follower support 22 are reset one after another, and the relative spacing of the follower support 22 is expanded to adapt to the expanded relative space between the second support block 16 and the first support block 15. When the first support block 15, the second support block 16 and the follower support 22 located under the frame can lift it from the bottom of the frame, the follower support 22 increases the contact points with the frame during the lifting process, further improving the stability of the frame during the lifting process.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
