Description

Technical Field

[0001] The invention relates to the field of automobile production, and in particular to a transfer skid and a transfer method between workstations of an automobile cargo box welding production line. Background Art

[0002] In the current automobile cargo box welding production line, the transfer of cargo boxes between workstations relies on manual dragging of the cargo boxes for transportation via unpowered rollers. This method of transportation is usually suitable for scenarios where the contact surface between the cargo box floor and the unpowered roller is smooth and flat. However, in some production lines, there is a process flange on the cargo box floor, which leads to some technical problems in the above transfer process. When the cargo box is manually dragged, the flange will collide with the roller, which will affect the life of the roller and may have an adverse effect on the quality of the cargo box. In order to solve the problem of direct collision between the flange and the roller, a new type of transfer device for between production line workstations is urgently needed. Summary of the invention

[0003] In view of the defects in the prior art, the purpose of the present invention is to provide a transfer slide and transfer method between workstations of a car cargo box welding production line, so as to avoid the situation where the cargo box flange directly hits the roller when the cargo box is transported on the unpowered roller.

[0004] In order to achieve the above technical effects, the present invention adopts the following technical solutions:

[0005] According to a first aspect of the present invention, there is provided a transfer skid between workstations of a car cargo box welding production line, comprising a front slider assembly, a rear slider assembly and a connecting frame;

[0006] Wherein, the front slider assembly includes a right front slider and a left front slider, and the rear slider assembly includes a right rear slider and a left rear slider; the length of the front slider assembly and the rear slider assembly is greater than the gap between the line rollers, and the material of the front slider assembly and the rear slider assembly is nylon;

[0007] The connecting frame is a rectangular frame welded by hollow rectangular tubes, the length of the connecting frame is adapted to the length of the cargo box, and the width is greater than the spacing between the line rollers; the front slider assembly and the rear slider assembly are detachably connected to the connecting frame by bolts;

[0008] The bottom of the front slider assembly and the rear slider assembly and the contact surface with the line roller are provided with a guide structure;

[0009] The cargo box contact surface of the front slider assembly is provided with a groove for engaging the flange of the cargo box bottom plate; the contact surfaces between the front and rear sliders and the cargo box bottom plate are processed by CNC to ensure that the convex ribs on the cargo box bottom plate are firmly clamped on the slider support surface.

[0010] Optionally, a reinforcing rib is provided between the left front slider and the right front slider.

[0011] Optionally, a reinforcing rib is provided between the right rear slider and the left rear slider.

[0012] Optionally, one or more reinforcing ribs are welded inside the connecting frame.

[0013] Optionally, a magnet is provided on the cargo box contact surface of the slider assembly, and the slider assembly is adsorbed to the bottom of the cargo box by magnetic force.

[0014] Optionally, the length of the front slider assembly and the rear slider assembly is 600 mm.

[0015] According to a second aspect of the present invention, a method for transferring between workstations of a car cargo box welding production line is provided, which is implemented by using the above-mentioned transfer skid between workstations of the car cargo box welding production line, and specifically comprises the following steps:

[0016] Step S1. Place the transfer slide on the line roller of the production station, and adjust the center line of the transfer slide to align with the axis of the line roller;

[0017] Step S2. Align the cargo box flange with the groove on the front slider assembly, and lower the cargo box with the clamp cylinder so that the cargo box flange is stuck in the groove on the front slider assembly of the transfer slide;

[0018] Step S3. Manually drag the transfer slide to roll the transfer slide with the cargo box along the line roller to the next station;

[0019] Step S4. Lift the cargo box by the clamp cylinder to make the cargo box flange disengage from the groove, thus completing the separation from the transfer slide.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The transport of cargo boxes by the transport skid provided by the present invention is stable, and the cargo box flanges are prevented from directly hitting the rollers when transported on unpowered rollers. Because the skid supports the front and rear of the cargo box and the overall length of the skid exceeds the gap between the rollers, the cargo box flanges and the skid itself will no longer hit the rollers, and the cargo box is very stable when transported on the rollers.

[0022] 2. The transfer slide provided by the present invention is easy to assemble and disassemble. When installing the transfer slide, you only need to align the cargo box flange with the slide groove of the transfer slide, and the clamp cylinder will lower the cargo box. The slide will fall steadily on the rollers relying on the cargo box's own weight. When disassembling, you only need to lift the cargo box with the clamp cylinder and manually pull out the slide.

[0023] 3. The transfer slide provided by the present invention has low manufacturing cost and is easy to operate. The main body material of the slide is nylon and hollow rectangular tube, which greatly reduces the overall quality and processing cost and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

Furthermore, the descriptions involving "first", "second", etc. in the application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

[0043] First Embodiment

[0044] like Figure 1 As shown, this embodiment provides a transfer skid between workstations of a car cargo box welding production line, comprising a front slider assembly, a rear slider assembly and a connecting frame 6. The front slider assembly and the rear slider assembly are detachably connected to the connecting frame 6 by bolts.

[0045] Among them, the front slider assembly includes a right front slider 1 and a left front slider 2, and a slider reinforcement rib 8 is arranged between the right front slider 1 and the left front slider 2. The rear slider assembly includes a right rear slider 3 and a left rear slider 4, and a slider reinforcement rib 8 is also arranged between the right rear slider 3 and the left rear slider 4. The front slider assembly and the rear slider assembly are both provided with a guide structure on the contact surface with the linear roller 9, and blocks are added on both sides of the contact surface to ensure that the transfer slide rolls smoothly on the linear roller 9 and will not rush out. In addition, a front slider groove 5 is provided on the cargo box contact surface of the front slider assembly, which is used to clamp the flange of the cargo box 10. The flange of the cargo box is clamped in the front slider groove 5, and the transfer slide rolls with the cargo box 10 on the linear roller 9 by relying on the dead weight of the cargo box 10. The contact surface between the front slider assembly and the rear slider assembly and the cargo box 10 is processed by CNC to ensure that the convex ribs on the cargo box bottom plate are firmly clamped on the supporting surface of the front and rear slider assemblies. The length of the front slider assembly and the rear slider assembly are both 600mm, which is larger than the gap between the line rollers 9, so as to avoid the transfer slide and the tail of the cargo box 10 being sunk into the pit between the line rollers 9 during transfer, causing the cargo box to be turned over and hit the line rollers 9. The material of the front slider assembly and the rear slider assembly is nylon, which reduces the dead weight and production cost and increases the convenience of operation.

[0046] The main body of the connecting frame 6 is a rectangular frame welded by four 20# hollow rectangular tubes. In addition, one or more reinforcing ribs are welded inside the connecting frame 6. The overall length of the connecting frame 6 is determined by the length of the cargo box, and the width is slightly wider than the width between the line rollers 9.

[0047] In addition, as an alternative, magnets (such as NdFeB permanent magnets) can be installed at the bottom of the front slider assembly and the rear slider assembly of the transfer sled, and the front slider assembly and the rear slider assembly can be adsorbed to the bottom of the cargo box 10 by magnetic force, replacing the connection method of the cargo box 10's own weight and the connection frame 6. This solution is suitable for special working conditions, such as when the cargo box 10 is light or cannot be fixed by its own weight.

[0048] like Figure 2 , Figure 3 As shown, when the cargo box 10 is transferred, first place the transfer slide on the line roller 9 of the production station, and adjust the center line of the transfer slide to align with the axis of the line roller 9. After the production of the station is completed, align the cargo box flange with the front slider groove 5, and the clamp cylinder lowers the cargo box 10 so that the cargo box flange is stuck in the front slider groove 5 of the transfer slide. The transfer slide can fall steadily on the line roller 9 by relying on the deadweight of the cargo box. Then, manually drag the transfer slide on the line roller 9 to the next station to stop, and repeat the above process. When disassembling, you only need to lift the cargo box 10 with the clamp cylinder to make the cargo box flange detach from the front slider groove 5, and manually pull out the transfer slide. It can be seen that the transfer slide is easy to install and disassemble.

[0049] When the above-mentioned transfer slide is used for cargo box transfer, on the one hand, because the transfer slide supports the cargo box 10 both in front and behind and the overall length of the transfer slide exceeds the gap between the wire rollers 9, the cargo box flange and the transfer slide itself will no longer fall into the pits between the wire rollers 9 and directly hit the wire rollers 9, and the cargo box 10 is very stable when transported on the unpowered wire rollers 9. On the other hand, the slide material is made of soft material nylon and lightweight material 20# hollow rectangular tube for rigid connection, with low manufacturing cost and convenient operation, which greatly reduces the overall quality and processing cost and is easy to use.

[0050] Second Embodiment

[0051] This embodiment provides a method for transferring between workstations of a car cargo box welding production line, which is implemented by using the transfer skid between workstations of the car cargo box welding production line described in the first embodiment, and specifically includes the following steps:

[0052] Step S1. Place the transfer slide on the production station line roller 9, and adjust the center line of the transfer slide to align with the axis of the line roller 9;
