Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding processing technology, specifically to a welding device for processing display racks that is easy to adjust. Background Technology
[0002] Display racks are typically used to display and store merchandise so that customers can clearly see and select the products. Among them, display shelves are a type of display rack. During the manufacturing process, welding equipment is used to connect multiple components of the display shelf to ensure its stability during use.
[0003] A search revealed that the Chinese patent "A Display Rack Steel Pipe Welding Fixture" (authorization announcement number CN216607819U) features four opposing adjustable clamps. Each clamp can simultaneously hold different steel pipe segments and move them in opposite directions, allowing the segments to come into contact and facilitating welding. The clamps can be used to assemble steel pipes into straight, cross, and perpendicular shapes, offering good applicability, flexibility, and ease of use, thus improving work efficiency and demonstrating greater advantages over existing technologies.
[0004] Although the above application allows for welding of steel pipe segments, the workpieces move the same distance after being fixed. When welding the steel pipe segments into a cross shape, the workers cannot guarantee that the four steel pipe segments will be aligned at the ends after movement after clamping them. Therefore, the workers need to first release the steel pipe segments from the fixation and adjust their positions before fixing them again, which is a rather cumbersome operation.
[0005] Based on this, the present invention designs a welding device for processing display racks that is easy to adjust in order to solve the above problems. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a welding device for processing display racks that is easy to adjust.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A welding device for processing display racks that is easy to adjust includes an operating table, a welding gun is provided at the top of the operating table, and a driving mechanism is provided on the inner wall of the operating table.
[0009] It also includes two limiting mechanisms, each limiting mechanism comprising an adjustment component and two movable rods slidably connected to the top of the operating table. A round rod is slidably connected to the upper end of the inner wall of each movable rod, with both ends of the round rod extending through the movable rod. A limiting plate is fixedly connected to the upper end of the surface of the round rod. The two limiting plates are symmetrical about the center of the operating table. Four mounting blocks are slidably connected to the top of the operating table, and a fixed frame is slidably connected to the top of each mounting block.
[0010] Furthermore, the limiting mechanism also includes a connecting rod fixedly connected to the lower end of the surface of the round rod, a telescopic rod fixedly connected between the lower ends of the surfaces of the two connecting rods, a first bolt rotatably connected to the surface of one of the connecting rods, the other end of the first bolt passing through the moving rod, and the surface of the first bolt being threadedly connected to the inner wall of the moving rod.
[0011] Furthermore, a second bolt is rotatably connected to the inner wall of the mounting block, and a sliding plate is threaded onto the surface of the second bolt. The top end of the sliding plate is fixedly connected to the bottom end of the fixing frame.
[0012] Furthermore, the adjustment assembly includes two fixed blocks fixedly connected to the bottom of the operating table, and a bidirectional lead screw rotatably connected between the opposite sides of the two fixed blocks. Two rings are threaded onto the surface of the bidirectional lead screw, and the bottom ends of the two moving rods pass through the operating table and are respectively fixedly connected to the surface of the rings.
[0013] Furthermore, the two ends of the bidirectional lead screw pass through the fixing blocks and are fixedly connected to knobs, and the surface of the knobs is provided with multiple grooves.
[0014] Furthermore, the top of the operating table is provided with a sliding groove that matches the moving rod, and the surface of the moving rod is slidably connected to the inner wall of the sliding groove.
[0015] Furthermore, the opposite sides of the movable rod and the mounting block are not located on the same horizontal plane.
[0016] Furthermore, the horizontal height of the limiting plate is higher than the horizontal height of the top of the fixed frame. Beneficial effects
[0017] The aforementioned limiting mechanism uses a limiting plate to limit the initial placement position of the steel pipe segments, thereby ensuring that the distance between the welding ends of the four steel pipe segments and the center point of the operating table is the same after they are fixed. The positions of the two horizontal or two vertical steel pipe segments are readjusted by a sliding fixed frame, thereby ensuring the alignment effect when welding the four steel pipe segments after they are moved. There is no need to readjust the position of the steel pipe segments after fixing and then unfixing them. The operation is relatively simple and ensures the welding effect when the four steel pipe segments are welded into a cross shape.
[0018] By setting up an adjustment component, it is convenient to adjust the distance between the moving rod and the fixed frame according to the length of the steel pipe section. During the adjustment process, rotating the double-acting screw causes the two rings to move the moving rods towards each other, which helps to make the two moving rods move the same distance, thus ensuring the practicality of the device.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0028] The present invention will be further described below with reference to the embodiments.
[0029] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5 A welding device for processing display racks that is easy to adjust, wherein a welding torch 200 is provided at the top of the operating table 100 and a drive mechanism 300 is provided on the inner wall of the operating table 100.
[0030] In this embodiment of the utility model, the top of the operating table 100 is provided with a placement groove for the welding gun 200. When the welding gun 200 is needed, it can be taken out from the placement groove.
[0031] The drive mechanism 300 includes a motor fixedly connected to the bottom of the operating table 100. The output shaft of the motor passes through the interior of the operating table 100 and is fixedly connected to a large bevel gear. Four small bevel gears are meshed on the surface of the large bevel gear. The included angle between the centers of two adjacent small bevel gears is 90 degrees. A lead screw is fixedly connected to one end of each of the four small bevel gears. A moving block is threaded onto the surface of the lead screw. A limit groove matching the moving block is opened at the top of the operating table 100. When the motor is started by the controller to drive the large bevel gear to rotate, the four small bevel gears will drive the corresponding lead screws to rotate synchronously.
[0032] It also includes two limiting mechanisms 400, each of which includes an adjusting component 470 and two movable rods 410 slidably connected to the top of the operating table 100. A round rod 420 is slidably connected to the upper end of the inner wall of the movable rod 410, with both ends of the round rod 420 passing through the movable rod 410. A limiting plate 430 is fixedly connected to the upper end of the surface of the round rod 420. The two limiting plates 430 are symmetrical about the center of the operating table 100. Four mounting blocks 480 are slidably connected to the top of the operating table 100, and a fixing frame 490 is slidably connected to the top of the mounting block 480.
[0033] In this embodiment of the utility model, a bidirectional threaded rod is rotatably connected to the inner wall of the fixed frame 490, and a slider is threadedly connected to the surface of the bidirectional threaded rod. A fixed plate is fixedly connected to the top of the slider. When fixing the steel pipe, rotating the bidirectional threaded rod causes the two sliders to move the corresponding fixed plates close to the steel pipe section at the same time.
[0034] When welding four steel pipe sections into a cross shape, the workers first move the four limiting plates 430 in the two sets of limiting mechanisms 400 to the front of the corresponding fixing frame 490, and align the welding ends of the four steel pipe sections with one side of the limiting plate 430. At this time, the distance between the welding ends of the four steel pipe sections is the same, thus ensuring that the distance between the four steel pipe sections and the center point of the operating table 100 is the same. The mounting block 480 is fixedly connected to the top of the moving block in the drive mechanism 300. After the fixing frame 490 fixes the steel pipe sections, the position of the two horizontal or two vertical steel pipe sections is readjusted through the sliding installation of the fixing frame 490, thus ensuring the alignment effect when welding the four steel pipe sections.
[0035] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the limiting mechanism 400 further includes a connecting rod 440 fixedly connected to the lower end of the surface of the round rod 420. A telescopic rod 450 is fixedly connected between the lower ends of the surfaces of the two connecting rods 440. A first bolt 460 is rotatably connected to the surface of one of the connecting rods 440. The other end of the first bolt 460 passes through the moving rod 410. The surface of the first bolt 460 is threadedly connected to the inner wall of the moving rod 410.
[0036] In this embodiment of the utility model, rotating the first bolt 460 will cause one of the connecting rods 440 to move away from the moving rod 410, and under the action of the telescopic rod 450, it will cause the other connecting rod 440 to move synchronously. When the first bolt 460 can no longer rotate, the two limiting plates 430 in the adjusting mechanism move to the front of the fixed frame 490. After the steel pipe is placed, the first bolt 460 is rotated in the opposite direction to make the limiting plates 430 move away from the steel pipe section, so as not to affect the movement of the steel pipe section.
[0037] The telescopic rod 450 includes a limiting frame and a limiting rod, with the surface of the limiting rod slidably connected to the inner wall of the limiting frame. The two telescopic rods 450 corresponding to the two limiting mechanisms 400 are staggered, so the two telescopic rods 450 do not affect each other during device operation.
[0038] By rotating the first bolt 460, under the action of the telescopic rod 450, it is beneficial to make the two limit plates 430 in the limit mechanism 400 move synchronously, thus ensuring the consistency of the device operation.
[0039] In some embodiments, such as Figure 5 As shown, in a preferred embodiment of the present invention, the inner wall of the mounting block 480 is rotatably connected to a second bolt 482, and the surface of the second bolt 482 is threadedly connected to a sliding plate 481. The top end of the sliding plate 481 is fixedly connected to the bottom end of the fixing frame 490.
[0040] In this embodiment of the utility model, after the steel pipe segment is fixed, the two horizontal second bolts 482 or the two horizontal second bolts 482 are rotated to make the corresponding slide plate 481 move through the fixed frame 490 to move the corresponding steel pipe segment, so that the welding ends of the two horizontal or two vertical steel pipe segments are far apart from each other. At this time, the four mounting blocks 480 are driven by the drive mechanism 300 to move the four steel pipe segments simultaneously toward the center point of the operating table 100. When the ends of two steel pipe segments are aligned, there is a certain distance between the ends of the other two steel pipe segments. At this time, the corresponding second bolts 482 are rotated to move the ends of the two steel pipe segments that are far apart from each other and put them into contact with the aligned steel pipe surface. At this time, the connection of the four steel pipe segments can be welded, so that multiple adjustments are not required.
[0041] In some embodiments, such as Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the adjustment component 470 includes two fixed blocks 471 fixedly connected to the bottom of the operating table 100. A bidirectional lead screw 472 is rotatably connected between the opposite sides of the two fixed blocks 471. Two rings 473 are threadedly connected to the surface of the bidirectional lead screw 472. The bottom ends of two moving rods 410 pass through the operating table 100 and are fixedly connected to the surface of the rings 473 respectively.
[0042] In this embodiment of the utility model, when it is necessary to adjust the distance between the moving rod 410 and the fixed frame 490 according to the length of the steel pipe section, the bidirectional lead screw 472 in the two adjusting components 470 is rotated respectively. The threads of the two rings 473 connected to the bidirectional lead screw 472 are opposite. Therefore, when the bidirectional lead screw 472 is rotated, the corresponding moving rod 410 will be driven to move towards each other through the two rings 473, which is beneficial to make the two moving rods 410 move the same distance.
[0043] In some embodiments, such as Figure 3 As shown, in a preferred embodiment of the present invention, the two ends of the bidirectional lead screw 472 pass through the fixing block 471 and are fixedly connected to the knob 474, and the surface of the knob 474 is provided with multiple grooves.
[0044] In this embodiment of the utility model, the operator can rotate either of the knobs 474 at both ends of the bidirectional lead screw 472 to drive the bidirectional lead screw 472 to rotate, which improves the convenience of the operator.
[0045] In some embodiments, such as Figure 2 As shown, in a preferred embodiment of the present invention, the top of the operating table 100 is provided with a sliding groove 110 that matches the moving rod 410, and the surface of the moving rod 410 is slidably connected to the inner wall of the sliding groove 110.
[0046] In this embodiment of the present invention, when the adjusting component 470 drives the moving rod 410 to move, the moving rod 410 will move within the slide groove 110, and the slide groove 110 helps to ensure the stability of the bidirectional lead screw 472 rotating to drive the moving rod 410 to move.
[0047] In some embodiments, such as Figure 1 As shown, in a preferred embodiment of the present invention, the opposite sides of the movable rod 410 and the mounting block 480 are not located on the same horizontal plane.
[0048] In this embodiment of the invention, the mounting block 480 does not contact the moving rod 410 when it moves horizontally, thus ensuring the stability of the device during operation.
[0049] In some embodiments, such as Figure 2 As shown, in a preferred embodiment of this utility model, the horizontal height of the limiting plate 430 is higher than the horizontal height of the top of the fixing frame 490.
[0050] In this embodiment of the utility model, when the limiting plate 430 moves to the front end of the fixing frame 490, the fixing frame 490 fixes the steel pipe segment, ensuring that the limiting plate 430 contacts the welded end of the steel pipe segment, thereby ensuring the limiting effect of the limiting plate 430 on the steel pipe segment.
[0051] It should be noted that the welding torch 200 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the welding torch 200 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.
[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
