Description

Technical Field

[0001] The utility model relates to the technical field of automobile production, and specifically relates to a rack for rear longitudinal beams. Background Art

[0002] In the automobile manufacturing industry, logistics management is crucial for ensuring production efficiency and product quality. With the improvement of the automation level of the production line, the accurate and efficient transportation of parts has become particularly important. Among them, the rear longitudinal beam, as one of the key components of the automobile chassis, is usually a long strip-shaped structural part used to connect the suspension system and the body at the rear of the vehicle.

[0003] At present, the transportation method of the rear longitudinal beam mainly includes using a special rack. The rack design often can only place parts in a single layer, resulting in low space utilization. During transportation, the rear longitudinal beam may shake due to vehicle bumps and other reasons, causing damage to the parts. The complex rack structure may increase the loading and unloading time and affect the efficiency of the production line. Content of the Utility Model

[0004] To achieve the above object, the utility model provides the following technical solution: A rack for rear longitudinal beams, including a rack body, on which a plurality of concave plates are fixed. On the inner side wall of the concave plate, a plurality of pairs of arc-shaped holes are arranged in a distribution from bottom to top, and a plurality of fixed columns are fixed, and a sliding rod sliding in the arc-shaped holes. A seesaw is rotatably connected between the sliding rod and the fixed column, and a torsion spring connected to the sliding rod and the concave plate is sleeved outside the fixed column.

[0005] Further, the same sides of a plurality of the sliding rods are connected in series by a plurality of connecting plates. The connecting plates are rotatably connected to the sliding rods, and waist-shaped holes through which the sliding rods pass are arranged on the connecting plates.

[0006] Further, two limiting sleeves attached to the inner wall of the concave plate are fixed outside the fixed column, and a limiting piece is fixed outside the sliding rod between the concave plate and the connecting plate.

[0007] Further, two baffle plates are fixed at the opening of the concave plate, and two columns are fixed on the rack body and distributed opposite to two of the concave plates with the openings facing the back.

[0008] Further, two bases are fixed at the bottom of the rack body, and a support plate and a plurality of shovel feet are fixed between the bases and the rack body.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0010] The material rack of the rear longitudinal beam moves the seesaw on the bottom layer, which squeezes the torsion spring and also drives the slide bar in the arc hole to move to the end. During the movement, the slide bar pulls the upper slide bar in the arc hole through the connecting plate, so that when placing a product, the upper seesaw can be opened to facilitate the placement of the next product, and so on. In this way, the products can be placed in multiple layers to improve the utilization rate, and the products can be limited by baffles and columns to prevent the products from shaking and causing damage during transportation.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figures 1-4 In this embodiment, a material rack for a rear longitudinal beam includes a frame body 1, six concave plates 5 are fixed on the frame body 1, the openings of every two concave plates 5 are oriented in the same direction, and three of the six concave plates 5 with different openings are grouped together, and three pairs of arc holes 8 are arranged and distributed equidistantly from bottom to top on the left and right side walls of the concave plates 5, and three fixed columns 15 are fixed thereto, as well as a slide bar 11 sliding in the arc holes 8, a seesaw 13 is rotatably connected between the slide bar 11 and the fixed column 15, and a torsion spring 10 connected to the slide bar 11 and the concave plate 5 is sleeved on the outer side of the fixed column 15.

[0018] In the above structure, when the seesaw does not support the product, the torsion spring will retract. By pushing the sliding rod to slide and be limited in the arc-shaped hole, and at the same time when the sliding rod moves, it can drive the seesaw to move simultaneously, so that the seesaw can be retracted during the non-use process. When in use, the seesaw is toggled outwards, and the seesaw drives the sliding rod to move to the limit position in the arc-shaped hole, so as to support the sliding rod, and at the same time the seesaw can be in a horizontal state to support the product. During the movement of the sliding rod, the torsion spring will also be twisted. When the product is removed, the seesaw can be automatically retracted by the torsion spring. At the same time, there are two groups of concave plates above, and each group can be stacked in multiple layers, so as to effectively improve the utilization rate of the rack.

[0019] As Figures 3-4 , between the left sides of the three sliding rods 11 are connected in series by two connecting plates 14. The connecting plates 14 are rotatably connected to the sliding rods 11, and waist-shaped holes through which the sliding rods 11 pass are opened at the top of one side of the connecting plates 14. When the bottom seesaw is toggled to support the product and the sliding rod slides in the arc-shaped hole, it will pull the bottom connecting plate downwards. Under the action of the waist-shaped hole, the upper sliding rod can have a certain movement range. When the bottom seesaw is horizontal, the connecting plate will pull the upper sliding rod to drive the second seesaw to be toggled to a certain angle for placing the next group of products, and so on. After placing one product, the next seesaw can be automatically unfolded, thus saving time and facilitating the placement of products.

[0020] Wherein, limiting sleeves 9 are fixedly arranged on the outer sides of both ends of the fixed column 15, and limiting pieces 12 are fixedly arranged on the outer side of the sliding rod 11 on the left side of the connecting plate 14. The limiting sleeves can limit the seesaw to prevent the limiting plate from moving independently. Then, an activity range of the connecting plate can be formed between the limiting pieces and the seesaw, so as to also limit the connecting plate and avoid deviation, affecting opening and closing.

[0021] As Figure 1 and 3 , two baffles 6 are fixedly arranged at the opening of the concave plate 5, and the plate surfaces of the baffles 6 extend out of the opening of the concave plate 5. Two upright columns 7 are fixedly arranged on the rack 1 and are distributed oppositely to two of the concave plates 5 with the openings facing the back. After the product is placed, through the cooperation between the multiple baffles and the limitation of the upright columns, it can effectively prevent the product from shaking and being damaged during transportation.

[0022] In addition, two bases 2 are fixedly arranged at the bottom of the rack 1. A support plate 3 and multiple shovel feet 4 are fixedly arranged between the bases 2 and the rack 1. Two round holes and an oval hole are opened at the bottom of the rack 1. The base and the rack are supported by the support plate and the shovel feet to form a certain distance and space, which is convenient for the forklift to lift and place. At the same time, the round holes and the oval hole at the bottom of the rack are convenient for AGV transportation, improving production efficiency.

[0023] The working principle of the above embodiments is as follows:

[0024] By prying the seesaw at the bottom in one set of concave plates to place the product, the seesaw rotates on the fixed column. At the same time, the sliding rod slides in the arc-shaped hole and twists the torsion spring. The arc-shaped hole can limit the sliding rod, so that the seesaw can support the product. During the movement of the sliding rod, it will pull the connecting plate at the bottom down. Since the waist-shaped holes are opened on the connecting plate, the sliding rod will move a certain distance in the waist-shaped holes during the pulling process. When pulling the upper sliding rod, after the bottom supports the product, the upper seesaw will automatically open and be in an inclined state, so that there is no need for manual prying again. It can be placed from bottom to top and then opened in sequence, realizing convenient placement of products. At the same time, the concave plates are divided into two groups, so that multi-layer placement can be realized, effectively improving the utilization rate of the rack. At the same time, during the placement process, the products are limited by the baffle and the column, which can prevent shaking and damage during transportation.
