[0032] 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 embodiments described 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 making creative efforts shall fall within the scope of protection of the present invention.

[0033] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0034] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0035] In recent years, the vehicle manufacturing industry has flourished, the number of household vehicles has continued to increase, and people's requirements for vehicle quality have continued to increase. Vehicle processing companies have continuously innovated and introduced new technologies and new methods to apply to vehicle processing production lines to improve the processing quality of vehicle parts.

[0036] At present, many vehicle processing and manufacturing companies use automated production lines to process and produce vehicles, and processing robots are responsible for the processing of vehicle parts. During the processing of vehicle parts, the processing robots perform corresponding processing on the vehicle parts according to preset programs. Taking the stamping processing of sheet metal parts as an example, after the sheet metal parts to be processed are transported to the processing table by a transport robot or a transport vehicle, the stamping robot will perform processes such as drawing, trimming, flanging, shaping and punching on the sheet metal parts to be processed. Each process requires the design of a corresponding processing table, and a handling robot is used to transport the sheet metal parts to be processed between each process. The processing table is used to support and fix the sheet metal parts to be processed.

[0037] However, according to the applicant's statistical research, since stamping processing generates large vibrations, the structure of the processing platform will become loose under the action of long-term vibrations, and the clamping effect on the sheet metal to be processed will be weakened, allowing the sheet metal to be processed to obtain a certain degree of freedom, thereby causing the sheet metal to be processed to move in the plane direction relative to the processing platform, thereby affecting the processing accuracy of the sheet metal, making the processing quality of the sheet metal difficult to control. At present, some technicians will use the method of regularly reinforcing the processing platform to solve this problem. Taking the production of sheet metal parts of a certain car model as an example, a total of 78 processing platforms are required. The average debugging and reinforcement time for each processing platform is 0.5 hours, and the total time for debugging and reinforcing each processing platform is 39 hours. During the debugging process, the sheet metal processing robot will stop production. Therefore, using this method to solve the above problem will obviously directly or indirectly generate a large amount of labor and time costs.

[0038] In view of this, the present invention proposes a bracket to solve the above technical problems.

[0039] See also Figure 1 In one embodiment of the present invention, the bracket 100 includes a main body 1 and a positioning portion 2, wherein the main body 1 and the positioning portion 2 are integrally formed, and the positioning portion 2 includes a positioning folding rod 21, a placement table 22 and a positioning plate 23. One end of the positioning folding rod 21 is connected to the main body 1, and the placement table 22 is horizontally arranged at the other end of the positioning folding rod 21. The placement table 22 is used to place the panel to be processed, and the positioning plate 23 is arranged at one end of the placement table 22. The positioning plate 23 is used to abut against the panel to be processed; the angle between the positioning plate 23 and the placement table 22 is α, then α satisfies: 90°≤α<180°.

[0040] Specifically, the main body 1 of the bracket 100 is a vertically arranged square column or cylindrical rod, and the positioning portion 2 is arranged at the top of the main body 1. The positioning folding rod 21 in the positioning portion 2 is formed by a combination of at least two straight rods. Since the panel to be processed needs to be accurately positioned at a preset position, and the preset position needs to be positioned according to the x, y, and z coordinates, in order to facilitate the determination of the length of each straight rod in the positioning folding rod 21, the straight rods in the positioning folding rod 21 need to be arranged along the extension direction of the x, y, and z axes. At the top end of the positioning folding rod 21 extending along the z-axis, a placement table 22 is provided. Since the panel to be processed needs to be placed horizontally, the top surface of the placement table 22 needs to be set horizontally, and the bottom surface of the panel to be processed is placed in contact with the top surface of the placement table 22. A positioning plate 23 is provided at one end of the placement table 22. In this embodiment, the positioning plate 23 is tilted at one end of the placement table 22, that is, there is an angle between the positioning plate 23 and the horizontal plane. Through this arrangement, when the panel to be processed is placed on the bracket 100 by the transport robot, if the placement position is not accurate, the panel to be processed can automatically slide onto the placement table 22 along with the tilted positioning plate 23, ultimately making the bottom surface of the panel to be processed fit with the top surface of the placement table 22, and at the same time making the edge of the panel to be processed abut against the positioning plate 23. In this embodiment, when the bracket 100 is in use, at least two brackets 100 need to be provided at different positions of the panel to be processed. Under the action of the positioning parts 2 in the at least two brackets 100, the panel to be processed can automatically center to the center position formed between the brackets 100. Due to the joint action of the positioning parts 2, the panel to be processed can stably stay in the preset position without deviation during the processing process. In addition, since the main body 1 and the positioning portion 2 are integrally formed, the bracket 100 will not become loose due to vibration, so that the positioning portion 2 can continue to function stably and avoid planar deviation relative to the bracket 100.

[0041] In the technical solution of the present invention, the bracket 100 includes a main body 1 and a positioning part 2, wherein the main body 1 and the positioning part 2 are integrally formed, and the positioning part 2 includes a positioning folding rod 21, a placing table 22 and a positioning plate 23. One end of the positioning folding rod 21 is connected to the main body 1, and the placing table 22 is horizontally arranged at the other end of the positioning folding rod 21. The placing table 22 is used to place the panel to be processed, and the positioning plate 23 is arranged at one end of the placing table 22. The positioning plate 23 is used to abut against the panel to be processed; the angle between the positioning plate 23 and the placing table 22 is α, and α satisfies: 90°≤α<180°. Through this arrangement, the sheet metal to be processed can automatically slide to the preset position under the action of the positioning plate 23 and gravity after being placed on the bracket 100, and during the processing, since the sheet metal to be processed and the positioning plate 23 are always in abutment, and the main body 1 and the positioning part 2 are integrally formed, the overall structure will not loosen due to vibration, so that the sheet metal to be processed will not be offset in the planar direction during the processing, thereby ensuring the processing quality of the sheet metal to be processed and avoiding affecting the yield rate of the finished sheet metal parts.

[0042] Taking the sheet metal production of a certain car model as an example, a total of 78 processing stands are required for production. According to statistics, the production cost of ordinary processing stands is about 1,500 yuan per stand, so the production cost of the sheet metal processing stands for this car model is 117,000 yuan. However, by adopting the bracket 100 in this embodiment and using the overall 3D printing technology, the production cost of each bracket 100 is about 200 yuan per stand, so the production cost of the bracket 100 is 15,600 yuan, and the production cost is reduced by 101,400 yuan. At the same time, the bracket 100 provided in this embodiment can be directly transported to the production line for installation after manufacturing is completed. The installation time is about 0.1 hours per stand, so it takes a total of 7.8 hours to install all the brackets 100. No secondary debugging is required during the sheet metal processing process. Compared with the 39 hours required for each debugging and reinforcement of ordinary processing stands, the use of the bracket 100 provided in this embodiment in sheet metal processing can significantly reduce downtime and increase total production. In addition, both ordinary processing stands and the bracket 100 in this embodiment require manual installation and debugging. Ordinary processing stands weigh about 6 kg each, and workers frequently moving the stands will directly increase the workers' labor intensity. The weight of the bracket 100 provided in this embodiment is only 0.4 kg each, which is only 7% of the weight of an ordinary processing stand, which can greatly reduce the workers' labor intensity. At the same time, the low-quality bracket 100 is easy for workers to install and debug, which can save a certain amount of installation time.

[0043] Furthermore, in one embodiment of the present invention, the bracket 100 further includes a support portion 3, which includes a connecting folding rod 31 and a support seat 32. One end of the connecting folding rod 31 is connected to the main body 1, and the support seat 32 is provided at the other end of the connecting folding rod 31. The top surface of the support seat 32 is provided at the same horizontal plane as the top surface of the placement table 22. The support seat 32 is used to support the plate to be processed. For details, please refer to Figure 1 and Figure 2 The top of the support portion 3 is spaced apart from the top of the mounting portion 7. The support portion 3 is primarily used to support and secure the panel to be processed. The panel to be processed can be divided into a processing area and an edge area. The edge area is fitted in contact with the support seat 32. When the processing area is subjected to a punching force, the support portion 3 can provide a supporting reaction force to the edge area, preventing the edge area from vertically displacing in the z-coordinate direction. During use, the edge area of ​​the panel to be processed is fitted in contact with both the placement table 22 and the top surface of the support seat 32. Both can simultaneously provide a supporting reaction force to the panel to be processed, ensuring that the vertical coordinates of the panel to be processed do not change, thereby improving processing accuracy.

[0044] Furthermore, in one embodiment of the present invention, the support base 32 includes a suction cup (not shown) and a mounting position 321. The suction cup is mounted on the mounting position 321, and the mounting position 321 is provided at the end of the connecting folding rod 31 away from the main body 1. By adding the suction cup to the mounting position 321, the support base 32 can firmly absorb the plate to be processed. The suction cup and the mounting position 321 are relatively fixed. The mounting position 321, the connecting folding rod 31 and the main body 1 are integrally formed. After the suction cup is absorbed by the plate to be processed, the plate to be processed can be fixed to the connecting folding rod 31. In this way, on the basis of limiting the vertical displacement of the plate to be processed, the planar displacement of the plate to be processed can be further limited, thereby improving the stability of the plate to be processed during the stamping process and further improving the processing quality. In addition, installing a suction cup on the mounting position 321 is only one of the implementation methods to achieve this purpose. In other implementation methods, an electromagnet is installed on the top of the mounting position 321. When the plate to be processed needs to be processed, the electromagnet is energized to generate magnetic force, and the plate to be processed is adsorbed on the electromagnet. The electromagnet and the mounting position 321 can be connected by threaded connection or welding, so that the plate to be processed can be fixed on the connecting folding rod 31, thereby limiting the vertical and planar displacement of the plate to be processed. After the processing of the plate to be processed is completed, the electromagnet is de-energized and loses its magnetic force, and the processed plate is transported to the next process by the handling robot.

[0045] In one embodiment of the present invention, the connecting folding rod 31 includes a horizontal connecting rod 311 and a vertical connecting rod 312. One end of the horizontal connecting rod 311 is connected to the main body 1, and the other end of the horizontal connecting rod 311 is connected to one end of the vertical connecting rod 312. The other end of the vertical connecting rod 312 is provided with a support seat 32. Figure 1 and Figure 2The connecting folding rod 31 is composed of at least two straight rods, all of which are arranged vertically or horizontally along the extension direction of the x, y and z axes. This arrangement can reduce the design difficulty and avoid the situation where the force transmission path is unclear or the force transmission size is difficult to calculate due to the occurrence of inclined rods. At the same time, the coordinates of the support seat 32 can be accurately set so that the support seat 32 can be accurately supported at the preset position of the panel to be processed.

[0046] In order to improve the overall rigidity of the bracket 100, in one embodiment of the present invention, the bracket 100 further includes a first diagonal brace 4 and a second diagonal brace 5. The two ends of the first diagonal brace 4 are connected to the main body 1 and the positioning folding rod 21, respectively, and the first diagonal brace 4 is tilted relative to the main body 1; the two ends of the second diagonal brace 5 are connected to the main body 1 and the connecting folding rod 31, respectively, and the second diagonal brace 5 is tilted relative to the main body 1. For details, please refer to Figure 1 and Figure 2 In this embodiment, the first diagonal support rod 4 is connected to one of the straight rods of the positioning folding rod 21, which is used to improve the vertical stiffness and planar stiffness of the positioning part 2 and reduce the vertical displacement and planar displacement of the positioning part 2 when subjected to external force; the second diagonal support rod 5 is connected to the horizontal connecting rod 311 in the connecting folding rod 31 of the supporting part 3, which is used to improve the vertical stiffness and planar stiffness of the supporting part 3. The inclination angle and length of the first diagonal support rod 4 and the second diagonal support rod 5 can be designed according to the stress conditions of the positioning part 2 and the supporting part 3. Specifically, vertical simulation software can be used to input external force into the positioning part 2 and the supporting part 3, and then verify whether the displacement deformation and stress distribution of the first diagonal support rod 4 and the second diagonal support rod 5 are qualified. The qualified verification standard is based on the positioning part 2 and the supporting part 3 not undergoing large deformation. It needs to be calculated specifically according to the processing accuracy requirements of the plate to be processed. If the first diagonal support rod 4 and the second diagonal support rod 5 are not added, the deformation of the positioning part 2 and the supporting part 3 can still meet the qualified verification standard. At this time, the first diagonal support rod 4 and the second diagonal support rod 5 can be used as a safety reserve to provide double protection for the processing accuracy of the plate to be processed.

[0047] Also, see Figure 3 In one embodiment of the present invention, a reinforcement block 8 is further provided at the connection between the supporting portion 3 and the main body 1 and at the connection between the positioning portion 2 and the main body 1, and a reinforcement block 8 is also provided between the connecting folding rod 31 and the positioning folding rod 21. At the same time, the connection between the straight rods in the connecting folding rod 31 and the connection between the straight rods in the positioning folding rod 21 are both provided with reinforcement blocks 8. This arrangement can further reduce the deformation of the supporting portion 3 and the positioning portion 2, and improve the overall rigidity of the bracket 100.

[0048] In one embodiment of the present invention, the bracket 100 further includes a gripping portion 6; the gripping portion 6 is disposed on the positioning folding rod 21, and / or, the gripping portion 6 is disposed on the connecting folding rod 31, and / or, the gripping portion 6 is disposed on the main body 1. Figure 1In this embodiment, to facilitate installation or removal of the bracket 100 by the operator, a grip portion 6 is provided on the bracket 100. The grip portion 6 can be positioned on the positioning lever 21, the connecting lever 31, or the main body 1, depending on the operator's operational needs. If space permits, the grip portion 6 can also be provided on two or three of these locations. This arrangement allows for convenient operation by simply gripping the grip portion 6 when transporting, installing, or removing the bracket 100, thereby improving the operator's operational efficiency.

[0049] In one embodiment of the present invention, the bracket 100 is an integrally formed part. Specifically, the main components of the bracket 100, including the main body 1, the positioning portion 2, the supporting portion 3, the first diagonal support rod 4, the second diagonal support rod 5, the gripping portion 6 and the reinforcing block 8, are all formed in a certain manner, using one of the materials such as PLA, ABS, PETG, etc., and produced by 3D printing. When designing the bracket 100, considering the production time of 3D printing, the main body 1, the connecting folding rod 31, the positioning folding rod 21, the first diagonal support rod 4 and the second diagonal support rod 5 can all be set as hollow rods, and the redundant structural parts are removed through topological optimization to reduce the overall mass of the bracket 100, while saving printing time and material costs. In addition, since the bracket 100 is an integrally formed part, it solves the problem that the structure of the ordinary processing platform is easy to loosen when it is subjected to vibration, and avoids the risk of the plate to be processed loosening and falling due to the loosening of the processing platform structure during stamping, which is conducive to reducing maintenance costs.

[0050] In one embodiment of the present invention, the bracket 100 further includes a mounting portion 7 and a threaded rod (not shown in the figure). The mounting portion 7 is connected to the main body 1 through the threaded rod. The mounting portion 7 is used to mount the main body 1 on a fixed base. Figures 1 to 2The mounting portion 7 is mounted on the bottom of the main body 1 and is coaxial with the main body 1. As the load-bearing member at the bottom of the bracket 100, the mounting portion 7 mainly bears the vertical load. In addition, there is a lot of friction between the mounting portion 7 and the fixed base, which results in a shorter service life than the rest of the bracket 100. Therefore, the mounting portion 7 is designed to be separated from the main body 1. When the mounting portion 7 needs to be replaced, it only needs to be removed from the threaded rod and replaced with a new mounting portion 7. At the same time, the mounting portion 7 adopts a solid design, with only one threaded hole reserved for installing the threaded rod. This setting can greatly improve the strength of the mounting portion 7 and reduce its replacement frequency. In this embodiment, the projection of the mounting portion 7 on the horizontal plane is circular, and the diameter of the projection is the plane size of the mounting hole in the fixed base. Therefore, in this embodiment, the mounting portion 7 is used to bear the vertical load transmitted by the main body 1, and the load is transmitted from the main body 1 to the fixed base, that is, a part of the main body 1 is inserted into the fixed base, thereby limiting the overall planar movement of the bracket 100. In another embodiment, the shape and size of the mounting portion 7 are set to correspond to the mounting hole of the fixed base, so that the mounting portion 7 can be fitted with the mounting hole, so that the mounting portion 7 plays the role of vertical positioning and planar positioning at the same time.

[0051] In one embodiment of the present invention, the positioning folding rod 21 includes a first horizontal rod 212, a second horizontal rod 213 and a vertical positioning rod 211 connected in sequence. The end of the first horizontal rod 212 away from the second horizontal rod 213 is connected to the main body 1, and the end of the vertical positioning rod 211 away from the second horizontal rod 213 is provided with a placement platform 22. Figure 1 and Figure 2 In this embodiment, in order to accurately set the positions of the placement table 22 and the positioning plate 23, the first horizontal rod 212 is used to adjust the x-axis coordinates of the placement table 22 and the positioning plate 23, the second horizontal rod 213 is used to adjust the y-axis coordinates of the placement table 22 and the positioning plate 23, and the vertical positioning rod 211 is used to adjust the z-axis coordinates of the placement table 22 and the positioning plate 23, so that the placement table 22 and the positioning plate 23 are accurately set at the preset positions. In addition, please refer to Figure 3 In order to increase the rigidity between the placement platform 22 and the vertical positioning rod 211 and prevent the placement platform 22 from tilting under the action of external force, a first reinforcing rib 24 is provided between the placement platform 22 and the vertical positioning rod 211; at the same time, in order to increase the rigidity between the positioning plate 23 and the vertical positioning rod 211, a second reinforcing rib 25 is provided between the positioning plate 23 and the vertical positioning rod 211.

[0052] See also Figure 3In one embodiment of the present invention, the side of the positioning plate 23 facing the placement table 22 is set to an arc surface. This setting can enable the arc surface to provide a certain vertical supporting force to the plate to be processed when the plate to be processed slides downward along the arc surface, so that the plate to be processed slowly slides onto the placement table 22, avoiding large vibrations or large impact forces on the placement table 22, which may reduce the service life of the placement table 22.

[0053] The present invention also proposes a positioning support structure, which includes a bracket 100. The specific structure of the bracket 100 refers to the above-mentioned embodiment. Since the positioning support structure adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here. Among them, the positioning support structure includes at least two brackets 100, and also includes a fixed base, at least two brackets 100 are installed on the fixed base, and the plate to be processed is placed on at least two brackets 100 at the same time. In one embodiment, there are four brackets 100, which are respectively arranged around the plate to be processed, and are used to position the plate to be processed at the center position formed by the four brackets 100. At the same time, due to the action of the four positioning parts 2 and the four supporting parts 3, the plate to be processed can be stably placed between the four brackets 100, so that the processing accuracy of the plate to be processed can be guaranteed during stamping.

[0054] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention.
