Description

Technical Field

[0001] The present invention relates to the field of welding technology, and specifically to a metal fitting display rack processing and welding device and its method. Background Art

[0002] A display rack is a common display appliance that can place different items inside the rack body for exhibition, for people to view and select. The display rack usually includes steel pipes and partitions fixed inside the steel pipes. The partitions are fixed by the steel pipes, so as to facilitate placing metal fittings and the like on the partitions for display. During the production and processing of the display rack, a welding process is required. The various components of the display rack are assembled through welding. During the welding process, a positioning device is needed to position the workpiece to be welded, so as to facilitate subsequent welding processing operations.

[0003] The publication number CN118682385B discloses a display rack processing and welding device. The problems proposed in its background art are as follows: For the positioning device used in the existing display rack welding process, the use position and clamping release of its adjusting clamp block are both controlled by the same transmission structure, resulting in an unchangeable movement speed ratio. When adjusting a large stroke, the clamp block moves slowly and cannot quickly reach the required position, which is rather troublesome and has poor flexibility and adaptability.

[0004] The publication number CN119216927A discloses a welding device for processing lifting platform fittings. The problems proposed in its background art are as follows: When welding the metal steel pipes on the guardrail, workers need to fix the steel pipes with one hand and operate the welding machine with the other hand. It is not easy to keep the steel pipes stable when manually fixing them by workers. Therefore, it is very easy to have the situation that the steel pipes are welded crooked, and it takes a lot of time during welding, and the efficiency is extremely low, etc.

[0005] Combining the existing technologies, the following problems exist:

[0006] When using the existing positioning device for welding metal fitting display racks, it is usually necessary to manually weld the frame at the welding position, that is, each steel pipe at the end corners, to perform basic positioning on the display rack, and then use the positioning device to position the remaining structures. The operation is cumbersome and cannot be adjusted according to the shape of the steel pipes, such as rectangular or circular. Therefore, it is not convenient to fix steel pipes of different shapes and not convenient to clamp and position steel pipes of different sizes, and the applicability is low. Referring to the above application documents, although it is convenient to adjust the position of the clamping mechanism in a large stroke, it is manually adjusted, which is more cumbersome compared with the existing electric control, etc. And although it can perform equidistant positioning on the steel pipes, it is necessary to weld the frame of the display rack first, and there are certain parts. To solve the above problems, a metal fitting display rack processing and welding device and its method are proposed. Summary of the Invention

Detailed implementation manners

[0063] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0064] Embodiment 1: Please refer to Figure 1 、 Figure 2 and Figure 3 , a processing and welding device for a metal fitting display rack, including spaced bottom beams 1, and further including an electric slide rail 2 fixedly arranged on the top of the bottom beam 1, a mounting seat 3 arranged at the sliding end of the electric slide rail 2 and vertically arranged with the bottom beam 1, and a moving through groove 4 opened on the top of the mounting seat 3 for the vertical movement of the steel pipe. A regulating mechanism 6 is arranged on the side wall of the mounting seat 3.

[0065] The electric slide rail 2 drives the mounting seat 3 to move on the top of the bottom beam 1, so as to adjust the distance between the mounting seats 3 to be applicable to display racks of different sizes. By providing the moving through groove 4, the position where the steel pipe is clamped by the positioning mechanism 7 can be adjusted, facilitating the reservation of the position of the support leg of the display rack at the bottom of the steel pipe.

[0066] Please refer to Figure 3 and Figure 4 , the regulating mechanism 6 includes:

[0067] A fixed seat 61 fixedly arranged on the side wall of the mounting seat 3. A positioning mechanism 7 extending to the top of the mounting seat 3 and used for clamping the steel pipe is movably arranged on the side wall of the fixed seat 61. First threaded rods 62 symmetrically arranged with the center point of the fixed seat 61 are rotatably arranged inside the fixed seat 61. A connecting mechanism 5 for connecting two first threaded rods 62 in the same fixed seat 61 is arranged at the middle end of the side wall of the mounting seat 3. The positioning mechanism 7 includes:

[0068] A first frame body 79 arranged on the top of the mounting seat 3. A second frame body 78 is movably arranged on the top of the first frame body 79. Positioning plates 77 are hinged on both sides inside the second frame body 78. First positioning components 72 are arranged on the sides of the positioning plates 77 away from each other, so as to respectively position the circular steel pipe and the rectangular steel pipe by adjusting the angles of the positioning plates 77 and cooperating with the first positioning components 72. An adjusting component 76 for adjusting the angles of the positioning plates 77 is arranged inside the second frame body 78.

[0069] Please refer to Figure 6 、 Figure 7 、 Figure 8 、 Figure 11 and Figure 12 , the adjusting component 76 includes:

[0070] The second threaded rod 763 is rotatably arranged inside the second frame body 78. A second sliding groove is formed inside the second frame body 78. Inside the second sliding groove are placed second sliders symmetrically arranged around the center point of the second sliding groove, and the second sliders are threadedly connected to the second threaded rod 763. The second threaded rod 763 is designed as a bidirectional screw. A second servo motor for driving the rotation of the second threaded rod 763 is fixedly arranged on the outer side of the second frame body 78.

[0071] The adjusting plate 764 is movably arranged on the side wall of the second slider, and the adjusting plate 764 is hinged to the side wall of the positioning plate 77 close to the second threaded rod 763. When the adjusting plate 764 moves, it drives the positioning plate 77 to rotate, thereby clamping the circular steel pipe. Support assemblies 73 for supporting the positioning plate 77 are arranged at the top and bottom of the positioning plate 77.

[0072] The bottom frame 71 is movably arranged on the side wall of the fixed seat 61, and the top of the bottom frame 71 is fixedly connected to the bottom of the first frame body 79.

[0073] The adjusting assembly 76 further includes:

[0074] The limiting plates 761 are fixedly arranged at the upper end and the lower end of the side of the adjusting plate 764 close to the second slider.

[0075] The limiting through grooves 762 are formed at the upper end and the lower end of the side wall of the second slider and are sleeved on the side wall of the limiting plate 761, so that the adjusting plate 764 and the second slider are relatively movably arranged. The inner walls of the limiting through grooves 762 extend to the outer side and the inner side of the second frame body 78 respectively.

[0076] The limiting blocks 765 are fixedly arranged inside the second frame body 78 and are respectively located at the top and bottom of the adjusting plate 764 to limit the position of the positioning plate 77.

[0077] In specific implementation, by hinging the side of the positioning plate 77 close to the opening of the second frame body 78, the side of the positioning plate 77 away from the opening of the second frame body 78 can rotate, so as to form an inclined plate body by rotating the positioning plate 77, and the circular steel pipe can be clamped and positioned by the positioning mechanisms 7 on both sides of the mounting seat 3.

[0078] When specifically adjusting the rotation angle of the positioning plate 77, start the second servo motor. The output shaft of the second servo motor drives the second threaded rod 763 to rotate through a coupling. While the second threaded rod 763 rotates, it drives the second slider to move along the second sliding groove. When the second slider moves, it drives the adjusting plate 764 to move through the limiting through groove 762 and the limiting plate 761. And because the adjusting plate 764 is hinged to the positioning plate 77, it drives the positioning plate 77 to rotate, thereby adjusting the angle of the positioning plate 77 to facilitate clamping and fixing circular steel pipes of different sizes.

[0079] By means of the limiting through slot 762 and the limiting plate 761 , the positioning plate 77 is hinged to the adjusting plate 764 , thereby increasing the degree of adjusting the angle of the positioning plate 77 and improving the applicability.

[0080] See also Figure 4 and Figure 5 A third slide groove is provided on the top of the first frame body 79, and a third slider is placed inside the third slide groove. A third threaded rod 74 extending into the third slide groove is rotatably provided on the outer side of the first frame body 79, and the side wall of the third slider is threadedly connected to the third threaded rod 74. A third servo motor for driving the third threaded rod 74 to rotate is fixedly provided on the outer side of the first frame body 79, and both the first frame body 79 and the second frame body 78 are designed in an open shape.

[0081] In specific implementation, after adjusting the assembly 76 to make the angle of the positioning plate 77 suitable for clamping the round steel pipe, the third servo motor is started, and the third servo motor drives the third threaded rod 74 to rotate through the coupling. The third threaded rod 74 rotates and drives the second frame 78 to move along the top of the first frame 79, so that the positioning plates 77 on both sides of the mounting seat 3 are close to each other, so as to clamp and fix the round steel pipe, so as to facilitate subsequent welding.

[0082] Since the first frame 79 and the second frame 78 are both designed to be open, it is convenient to place the steel pipe. The top two sides of the first frame 79 are interactively connected with the bottom two sides of the second frame 78 to limit the movement of the second frame 78 and improve the stability of the movement of the second frame 78.

[0083] See also Figure 4 , the support assembly 73 comprises:

[0084] The support plate 731 is arranged at the top and bottom of the positioning plate 77, and one side of the support plate 731 is fixedly sleeved on the side wall of the hinge shaft of the hinged positioning plate 77, and the other side of the support plate 731 is fixedly connected to the side of the positioning plate 77 close to the second threaded rod 763. The support plate 731 is designed in an arc shape, and the arc angle of the support plate 731 is adapted to the hinge rotation angle of the positioning plate 77;

[0085] The supporting through slots 732 are formed inside the second frame 78 and are located at the top and bottom of the positioning plate 77 . The inner walls of the supporting through slots 732 are in contact with the side walls of the supporting plate 731 .

[0086] In specific implementation, when the positioning plate 77 rotates, the positioning plate 77 drives the support plate 731 to rotate along the support through groove 732, thereby supporting one end of the positioning plate 77 away from the opening of the second frame 78, thus improving the stability of the positioning plate 77 for extruding and positioning the steel pipe. Moreover, the support plate 731 is arc-shaped designed. While not affecting the rotation of the positioning plate 77, the side wall of the support plate 731 is always partially located within the support through groove 732, thereby ensuring the limiting effect on the positioning plate 77.

[0087] Please refer to Figure 3 , first sliding grooves are respectively formed on the mutually remote sides of the fixed seats 61. First sliders symmetrically arranged with respect to the center points of the first sliding grooves are respectively placed inside the first sliding grooves. The side walls of the two first sliders are respectively in threaded connection with the side walls of the two first threaded rods 62. Moreover, the threading directions of the two first threaded rods 62 within the same fixed seat 61 are opposite. The first sliders are fixedly connected to the bottom frame 71. The first threaded rods 62 on both sides of the same mounting plate are in transmission connection. A first servo motor for driving one of the first threaded rods 62 to rotate is fixedly provided on the side wall of the mounting plate;

[0088] In specific implementation, the first servo motor drives the first threaded rod 62 to rotate, thereby driving the first slider to move along the first sliding groove, so as to drive the positioning mechanism 7 to move, thereby adjusting the position of the positioning mechanism 7 to clamp and position display racks of different sizes, thus facilitating the welding of display racks of different sizes.

[0089] Please refer to Figure 9 , Figure 10 and Figure 11 , the first positioning component 72 includes:

[0090] A housing 727, fixedly arranged on the mutually remote sides of the positioning plate 77.

A second positioning component 75 for clamping the rectangular steel pipe from the front and the back is arranged inside the second frame 78. A first electromagnet 726 is fixedly provided on the inner side of the clamping plate 725. A second electromagnet 721 is fixedly provided on the inner wall of the housing 727 to drive the clamping plate 725 to move through the repulsive force or attractive force generated by the first electromagnet 726 and the second electromagnet 721;

[0091] Positioning rods 722, fixedly arranged on the inner side of the clamping plate 725 and located on both sides of the first electromagnet 726. The sides of the positioning rods 722 remote from the clamping plate 725 extend outside the housing 727, so that the positioning rods 722 move along with the clamping plate 725, thereby limiting the clamping plate 725;

[0092] The first limiting ring 724 is fixedly arranged on the inner wall of the housing 727, and the inner wall of the first limiting ring 724 is sleeved on the side wall of the positioning rod 722;

[0093] The second limiting ring 723 is fixedly sleeved on the side wall of the positioning rod 722 and is located on the side of the first limiting ring 724 away from the clamping plate 725. A first spring is sleeved on the side wall of the positioning rod 722 and between the first limiting ring 724 and the second limiting ring 723.

[0094] In specific implementation, when clamping and positioning a rectangular steel pipe, first reset the positioning plate 77 through the adjusting assembly 76 so that the adjusting plate 764 is horizontally arranged and thus horizontal with the side wall of the rectangular steel pipe, facilitating clamping the rectangular steel pipe through the first positioning assembly 72. After the positioning plate 77 is adjusted, start the first electromagnet 726 and the second electromagnet 721, and make the sides of the first electromagnet 726 and the second electromagnet 721 close to each other generate a repulsive force, thereby pushing the first electromagnet 726 and the clamping plate 725 to move to clamp and position both sides of the rectangular steel pipe;

[0095] When the first electromagnet 726 and the clamping plate 725 move, they drive the positioning rod 722 to move along the housing 727, thereby limiting the movement of the clamping plate 725 and improving the stability of its movement. By setting the first limiting ring 724 and the second limiting ring 723, it is convenient to drive the clamping plate 725 to approach the second electromagnet 721 under the action of the first spring after the repulsive force between the first electromagnet 726 and the second electromagnet 721 is cancelled, so that the clamping plate 725 moves into the positioning plate 77, avoiding subsequent clamping and positioning of a circular steel pipe. And by making the sides of the first electromagnet and the second electromagnet 721 close to each other generate an attractive force, it is further convenient to make the clamping plate 725 move into the positioning plate 77;

[0096] During specific operation, the repulsive force or attractive force can be generated on the sides of the first electromagnet and the second electromagnet 721 close to each other by adjusting the current direction, etc., for convenient actual control. This is prior art and will not be elaborated here.

[0097] Please refer to Figure 6 and Figure 8 , the second positioning assembly 75 includes:

[0098] The positioning column 751 is movably arranged inside the second housing 78 and extends outside the second housing 78. A placement through groove 752 for placing the second threaded rod 763 is formed on the side wall of the positioning column 751 to limit the movement of the positioning column 751 from interfering with the rotation of the second threaded rod 763. An electric push rod for driving the movement of the positioning column 751 is fixedly arranged outside the second housing 78.

[0099] In specific implementation, after the two sides of the rectangular steel pipe are positioned by the first positioning component 72, the positioning column 751 is driven to move by an electric push, so as to clamp and fix the rectangular steel pipe from the other two sides through the positioning column 751, thereby clamping and fixing the rectangular steel pipe from its four sides, improving the stability of fixing the rectangular steel pipe, facilitating subsequent welding, and the position of the second frame body 78 can be adjusted by the third servo motor, cooperating with the second positioning component 75, further improving the flexibility of clamping and fixing the other two sides of the rectangular steel pipe;

[0100] By providing a placement through groove 752, it is convenient for the rotation of the second threaded rod 763 when the positioning column 751 moves, thus facilitating actual use.

The sides of the first ring body 55 and the second ring body 57 close to each other are both designed to be arc-shaped.

[0104] The connection mechanism 5 further includes:

[0105] The third ring body 56 is fixedly sleeved on the inner wall of the mounting sleeve 53, and the inner wall of the third ring body 56 is sleeved on the side wall of the guide rod 593. A fourth ring body 54 is fixedly sleeved on the side wall of the guide rod 593. A second spring is sleeved on the side wall of the guide rod 593 and on the side where the third ring body 56 and the fourth ring body 54 are close to each other. A rotation through groove 596 for sleeving the rotating rod 592 is provided in the middle of the side wall of the guide rod 593, and the middle of the side wall of the rotating rod 592 is designed in a frustum shape.

[0106] During specific implementation, when the positioning mechanism 7 is used for a long time, the internal mechanical structure, electrical devices, etc. will be damaged. To facilitate the maintenance and replacement of the positioning mechanism 7, the connecting mechanism 5 is provided to facilitate the disassembly and assembly of the positioning mechanism 7, so as to facilitate the maintenance of the positioning mechanism 7 for long-term use.

[0107] When the positioning mechanism 7 needs to be installed, the staff pulls up the plug rod 595. Then, the connecting seat 51 is placed on one side where the fixed seats 61 are close to each other, and then the guide rod 593 is pressed to insert the guide rod 593 into the mounting seat 3. Then, the plug rod 595 is released. Under the action of the third spring, the retaining ring 594 and the plug rod 595 are reset, so as to insert into the slot at the top of the guide rod 593 to fix the position of the guide rod 593 and fix the connecting seat 51 to the mounting seat 3 at the same time. During this process, the staff sleeved the block 59 into the slot provided in the clamping seat 58 to connect the second threaded rod 763 and the rotating rod 592. And when the second threaded rod 763 rotates, it drives the spline sleeve 52 to rotate in the connecting seat 51 through the spline groove provided in the side wall of the spline sleeve 52 and the rotating rod 592, so as to connect the two second threaded rods 763 on the same side of the mounting seat 3 to make them rotate synchronously, so as to facilitate the actual adjustment of the position of the positioning mechanism 7 for use.

[0108] When disassembly is required, operate in reverse to remove the connecting seat 51, and then rotate the second threaded rod 763 to move the first slider to one side where the fixed seats 61 are close to each other, so as to remove the clamping mechanism.

[0109] When moving through the guide rod 593, the first ring body 55 is driven to move, so that the first ring body 55 squeezes the second ring body 57. After the insertion rod 595 fixes the guide rod 593, the first ring body 55 positions the second ring body 57, that is, locks the connection between the card seat 58 and the card block 59 to prevent it from loosening, thereby ensuring the stability of transmission.

[0110] By designing the middle end of the guide rod 593 to be frustum-shaped, the second ring body 57 has sufficient moving space, which is convenient for the separation of the card seat 58 and the card block 59.

[0111] By rotatably connecting the second ring body 57 with the rotating rod 592 and slidingly connecting it with the third groove, the stability of the first ring body 55 limiting the second ring body 57 is improved, and it does not affect the normal rotation of the rotating rod 592.
