Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing, and in particular to a multi-point skid. Background Technology
[0002] In automobile manufacturing, skids are crucial equipment for transporting and positioning the car body during welding, painting, and other processes. Currently, most conventional primer skids in the industry are four-point type, using four sets of outriggers to simultaneously support and lock the car body. While this meets the needs of common models in newly built standardized production lines, it has significant shortcomings in existing production line retrofit scenarios. The contradiction between support strength and equipment interference: The existing production line is limited by the space of the welding and skid changing station and the size of the painting hoist. If the four-point skid layout is used, the distance between the outriggers needs to be reduced to avoid interference, resulting in a support size that is too small and cannot distribute the body load of SUVs and other vehicles, thus failing to meet the strength requirements. Functional coupling limitations: Four-point outriggers need to simultaneously bear the functions of support and locking. It is difficult to balance both at the interference point. If the support is abandoned, the strength will be insufficient. If the locking is forcibly set, it will cause a collision. Utility Model Content
[0003] The purpose of this invention is to provide a multi-point skid to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a multi-point skid, comprising a skid frame for supporting the vehicle body, wherein the skid frame is provided with five sets of support legs, including a first front support leg, a first rear support leg, a second rear support leg, a third rear support leg, and a second front support leg; The first and second front outriggers are locking outriggers with locking function; The first and third rear support legs are support legs with positioning and support functions; The second rear outrigger includes a support column, a support plate fixed to the top of the support column, a movable pressure rod, and a locking pin. A pressure plate is sleeved on the outer side of the movable pressure rod, and a locking block is fixedly installed at the bottom of the movable pressure rod. When the movable pressure rod is pressed down, the locking block is driven to pass through the opening in the vehicle floor until it is in contact with the support plate. The pressure plate is pressed against the upper part of the vehicle floor, and at the same time, the locking pin is driven to pass through the locking hole of the locking block to achieve locking.
[0005] Preferably, multiple guide plates are fixedly installed on the support plate, and the locking pin is movably inserted between the multiple guide plates.
[0006] Preferably, the support plate has a positioning port for limiting the position, and the end of the locking pin has a bent section, which is movably inserted into the positioning port of the support plate.
[0007] Preferably, the first and second front outriggers include an eccentric pin locking mechanism, which locks or releases the vehicle body through the lifting and lowering movement of the eccentric pin.
[0008] Preferably, the first rear support leg and the third rear support leg include a support column and a positioning support block disposed at the top of the support column, wherein the positioning support block is provided with a positioning pin.
[0009] Preferably, the bottom surface of the pressure plate is a dotted contact surface.
[0010] The technical effects and advantages of this utility model are as follows: 1. This multi-point skid features five outriggers. The first and second front outriggers are locking outriggers with locking functions, while the first and third rear outriggers are support outriggers with positioning and support functions. The second rear outrigger provides both support and locking, achieving a separate layout for support and locking functions. Without increasing the overall size of the skid frame, the interference area between the welding skid change station and the painting hoist can be avoided by staggering the positions of the locking and support points. Simultaneously, the distributed support of the five outriggers effectively disperses the SUV body load, significantly improving support strength compared to a four-point skid, fully meeting the dual requirements of interference-free operation and high strength for existing production line modifications.
[0011] 2. This multi-point skid uses an eccentric pin locking mechanism for the first and second front outriggers. Locking or releasing can be completed through simple lifting movements. The structural design is simple, and employees can quickly master the operation method without professional training. The movable pressure rod of the second rear outrigger is designed to cooperate with the locking pin. Pressing the movable pressure rod will drive the pressure plate to press the vehicle body and the locking block to fit against the support plate. Then, inserting the locking pin will complete the locking. The whole process does not require the assistance of tools. The guide plate on the support plate can guide the locking pin to be inserted accurately. The cooperation between the positioning port and the bent section of the locking pin can prevent the pin from loosening and avoid locking failure. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] This utility model provides, for example Figures 1-2 The multi-point skid shown includes a skid frame for supporting the vehicle body, and five sets of support legs are provided on the skid frame, including a first front support leg 1, a first rear support leg 2, a second rear support leg 3, a third rear support leg 4, and a second front support leg 5. The first front support leg 1 and the second front support leg 5 are locking support legs with locking function; The first rear support leg 2 and the third rear support leg 4 are support legs with positioning and support functions; The second rear outrigger 3 includes a support column 36, a support plate 35 fixed to the top of the support column 36, a movable pressure rod 31, and a locking pin 34. A pressure plate 32 is sleeved on the outside of the movable pressure rod 31, and a locking block 33 is fixedly installed at the bottom of the movable pressure rod 31. When the movable pressure rod 31 is pressed down, the locking block 33 is driven to pass through the opening in the vehicle floor until it is in contact with the support plate 35. The pressure plate 32 is pressed against the top of the vehicle floor, and at the same time, the locking pin 34 is driven to pass through the locking hole of the locking block 33 to achieve locking.
[0016] Of the five outriggers, the first front outrigger 1 and the second front outrigger 5 are locking outriggers with locking functions; the first rear outrigger 2 and the third rear outrigger 4 are support outriggers with positioning and support functions; and the second rear outrigger 3 has both support and locking functions, achieving a separate layout for support and locking functions. Without increasing the overall size of the skid frame, the interference area between the welding skid change station and the painting hoist can be avoided by staggering the positions of the locking and support points. Simultaneously, the distributed support of the five outriggers effectively disperses the SUV body load, significantly improving support strength compared to a four-point skid, fully meeting the dual requirements of interference-free operation and high strength for existing production line modifications.
[0017] Furthermore, multiple guide plates are fixedly installed on the support plate 35, and the locking pin 34 is movably inserted between the multiple guide plates.
[0018] Furthermore, the support plate 35 is provided with a positioning port for limiting the position, and the end of the locking pin 34 is provided with a bent section, which is movably inserted into the positioning port of the support plate 35.
[0019] Furthermore, the first front outrigger 1 and the second front outrigger 5 include an eccentric pin locking mechanism, which locks or releases the vehicle body through the lifting and lowering movement of the eccentric pin.
[0020] Furthermore, the first rear support leg 2 and the third rear support leg 4 include a support column and a positioning support block disposed at the top of the support column, and a positioning pin is disposed on the positioning support block.
[0021] Furthermore, the bottom surface of the pressure plate 32 is a dotted contact surface.
[0022] The first front outrigger 1 and the second front outrigger 5 adopt an eccentric pin locking mechanism, which can be locked or released by a simple lifting movement. The structure is simple and employees can quickly master the operation method without professional training. The movable pressure rod 31 of the second rear outrigger 3 is designed to cooperate with the locking pin 34. Pressing the movable pressure rod 31 will drive the pressure plate 32 to press the body and the locking block 33 to fit against the support plate 35. Then, inserting the locking pin 34 will complete the locking. The whole process does not require the assistance of tools. The guide plate on the support plate 35 can guide the locking pin 34 to be inserted accurately. The cooperation between the positioning port and the bent section of the locking pin 34 can prevent the pin from loosening and avoid locking failure.
[0023] The SUV body is transferred to the skid frame using a hoisting device, and then slowly lowered until the pre-set support area at the bottom of the vehicle body contacts the positioning support blocks at the top of the first rear outrigger 2 and the third rear outrigger 4. The positioning pins on the positioning support blocks engage with the positioning holes at the bottom of the vehicle body to achieve initial lateral and longitudinal positioning of the vehicle body on the skid. Simultaneously, the struts of the first rear outrigger 2 and the third rear outrigger 4 provide vertical stability support for the vehicle body, ensuring that there is no significant swaying or shifting after placement.
[0024] The operator performs locking operations on the first front outrigger 1 and the second front outrigger 5 respectively: by rotating or pressing the eccentric pin locking mechanism drive on the first front outrigger 1 and the second front outrigger 5, the eccentric pin is raised and lowered along a preset trajectory until the locking end of the eccentric pin engages with the front locking groove at the bottom of the vehicle body. At this time, the eccentric structure of the eccentric pin generates a lateral preload, firmly fixing the front end of the vehicle body to the skid frame, preventing the front end of the vehicle body from lifting or moving laterally during transportation or process changes.
[0025] For the second rear support leg 3, the rear end locking is performed as follows: The operator holds the top of the movable pressure bar 31 with both hands and applies downward pressure. The movable pressure bar 31 moves downward along the axis, causing the locking block 33 fixed at the bottom to pass through the preset opening on the vehicle body floor until the bottom surface of the locking block 33 is completely in contact with the surface of the support plate 35 at the top of the support column 36. During the downward movement of the movable pressure bar 31, the pressure plate 32 sleeved on its outer side presses against the upper surface of the vehicle floor simultaneously, forming uniform pressure through the point contact surface of the pressure plate 32 to prevent local deformation of the vehicle floor. Take the locking pin 34 and insert it along the gap between the multiple guide plates fixed on the support plate 35, so that the locking pin 34 passes through the locking hole on the locking block 33 and the corresponding hole on the support plate 35 in sequence, until the bent section at the end of the locking pin 34 is completely inserted into the positioning hole of the support plate 35. The positioning hole limits the bent section to prevent the locking pin 34 from loosening in the subsequent vibration environment, thus completing the locking and fixing of the rear end of the vehicle body.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
