Technical Field

[0001] The utility model relates to a placing platform for workpiece processing, in particular to a placing platform for body workpiece processing. Background Art

[0002] As a part of the vehicle body, the function of the door is to provide a passage for the driver and passengers to enter and exit the vehicle, isolate the interference outside the vehicle, and reduce the side impact to a certain extent. During the manufacturing process, the door needs to go through a series of processes such as stamping, cutting, welding, and painting. In the production and processing of the door, the door needs to use a placement platform before and after processing. Usually, the doors are placed side by side on the placement platform and fixed on the placement platform.

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. 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.

[0021] Embodiment: A placing platform for processing a body workpiece, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a workpiece placement rack 1, a slide rail 2, a limit rod 3, a cross plate 4, a cylinder 5, a connecting rod 51, an n-shaped clamping plate 6 and a limit assembly. The front part of the workpiece placement rack 1 is opened, and the inner bottom array of the workpiece placement rack 1 has ten slide rails 2 parallel to the width side of the workpiece placement rack 1. According to actual use or design needs, the number of slide rails 2 can be deleted, and the car door is slidably placed on the slide rail 2. Ten limit rods 3 are arranged on the upper left side of the slide rail 2. The rear end of the limit rod 3 is connected to the workpiece placement rack 1. The number of the limit rods 3 is consistent with the number of the slide rails 2. The left and right side walls of the workpiece placement rack 1 are symmetrically provided with cross plates 4. A connecting rod 51 is slidably connected between the two cross plates 4. The connecting rod 51 is a telescopic rod. The left end of the connecting rod 51 is a fixed end of the telescopic rod. It is fixedly installed on the left side cross plate 4, the movable end of the connecting rod 51 slides through the right side cross plate 4, the connecting rod 51 passes through the midpoint of the cross plate 4, and ten n-type clamps 6 for providing limit clamping for the left side of the body workpiece are evenly spaced on the connecting rod 51. The connecting rod 51 is fixedly connected to the n-type clamp 6, and the number of the n-type clamps 6 is consistent with that of the slide rail 2. A rubber pad 61 is arranged on the right side of the n-type clamp 6. The setting of the rubber pad 61 helps to protect the car door. A cylinder 5 for driving the connecting rod 51 to slide is installed on the cross plate 4, and the piston rod of the cylinder 5 is connected to the right end of the connecting rod 51. A limit assembly for limiting the right side of the body workpiece is arranged between the two cross plates 4, and the limit assembly cooperates with the n-type clamp 6 to fix the body workpiece to the inner side of the workpiece placement rack 1.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, the limit assembly includes a guide rod 17, a threaded sleeve 71 and an n-type clamping plate 28. The guide rods 17 are symmetrically arranged on the front and rear sides with the connecting rod 51 as the center. An n-type clamping plate 28 is movably arranged between the two guide rods 17 to cooperate with the n-type clamping plate 16 to limit and clamp the body workpiece. The number of the n-type clamping plates 28 is consistent with the number of the n-type clamping plates 16. The connecting rod 51 slides through the midpoint of the n-type clamping plate 28. The n-type clamping plate 28 is arranged on the right side of the n-type clamping plate 16, and the n-type clamping plate 16 is fixedly arranged. On the connecting rod 51, the rear end of the n-type clamp 28 is slidably connected to the rear guide rod 1 7, and the front end of the n-type clamp 28 is threadedly connected to the threaded sleeve 71 rotatably arranged on the front guide rod 7. The threaded sleeve 71 is arranged between two adjacent n-type clamps 28. The threaded sleeve 71 rotates to drive the n-type clamp 28 to move horizontally along the connecting rod 51, thereby clamping the door limit or releasing the door limit clamping, thereby realizing the limit fixing of doors of different thicknesses, or releasing the limit clamping function of a single door.

[0023] like Figure 1 and Figure 5 As shown, a stretching assembly for pulling the workpiece out of the workpiece placement rack 1 is provided on the upper inner side of the workpiece placement rack 1, and the stretching assembly includes a connecting plate 9, an L-shaped stretching member 10, a guide rod 11 and a spring 111. A connecting plate 9 parallel to the length direction of the workpiece placement rack 1 is provided on the back of the workpiece placement rack 1, and a guide rod 11 adapted to the slide rail 2 is evenly spaced apart on the side of the connecting plate 9 facing the inside of the workpiece placement rack 1. The guide rod 11 is slidably connected with the L-shaped stretching member 10, and the guide rod 11 is hexagonally arranged. The hexagonal arrangement can avoid the displacement of the L-shaped stretching member 10 when it moves on the guide rod 11, and a spring 111 is arranged between the L-shaped stretching member 10 and the front end of the guide rod 11 for facilitating the resetting of the L-shaped stretching member 10.

[0024] like Figure 1 As shown, telescopic legs 12 and universal wheels 13 are arranged in parallel at the four corners of the bottom of the workpiece placement rack 1. The telescopic legs 12 and universal wheels 13 are used separately. When it is necessary to provide a stable supporting force for the workpiece placement rack 1, the telescopic legs 12 extend downward and the universal wheels 13 are suspended in the air; when the workpiece placement rack 1 needs to be moved conveniently, the telescopic legs 12 retract upward, the universal wheels 13 fit into the ground, and convenient movement is achieved through the universal wheels 13; an anti-slip pad 121 is arranged at the bottom of the telescopic legs 12.

[0025] When in use, the car door is placed on the workpiece placement rack 1 through the slide rail 2, and the limit rod 3 provides support for the upper left side of the car door. After the car door is placed, the piston rod of the cylinder 5 extends and moves, and the piston rod of the cylinder 5 drives the connecting rod 51 to move to the right, and the connecting rod 51 drives the n-type clamping plate 6 thereon to move to the right, thereby providing a supporting force for the left side of the car door, and by rotating the threaded sleeve 71, the n-type clamping plate 2 8 moves in the direction of the n-type clamping plate 6, thereby limiting and clamping car doors of different thicknesses, so that they are stably placed on the workpiece placement rack 1; when the car door needs to be taken out from the workpiece placement rack 1, when all the car doors need to be taken out, the cylinder 5, the piston rod of the cylinder 5 drives the n-type clamping plate 6 to move to the left side through the connecting rod 51, thereby releasing the limit of the car door. When a car door needs to be taken out, the threaded sleeve 71 corresponding to the car door is rotated, and the threaded sleeve 71 drives the n-type clamping plate 2 8 to move away from the n-type clamping plate 6, thereby releasing the limit of the single car door, and then the L-shaped stretching member 10 is pulled forward, and the hook part on the rear side of the L-shaped stretching member 10 hooks the end of the car door close to the rear side of the workpiece placement rack 1, thereby the L-shaped stretching member 10 pulls the car door to slide forward along the slide rail 2, so that the car door can be easily taken out from the workpiece placement rack 1.

[0026] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments may be designed without departing from the scope of the present invention. Therefore, the scope of the present invention should be limited only by the appended claims.
