DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Embodiment 1

[0037] like Figure 1 As shown, a welding device for producing lamp poles for outdoor lamps includes a table 1, a support frame 2 is fixedly connected to the middle of the upper end of the table 1, a welding structure 5 fixedly connected to the upper end of the support frame 2 is arranged on the top wall of the inner surface of the support frame 2, an interface grinding structure 3 is arranged in the middle of the upper end of the table 1, and a lamp pole clamping structure 4 is symmetrically arranged on the left and right of the upper end of the table 1.

[0038] During the operation of this embodiment, the lamp poles are first placed on the lamp pole clamping structures 4 on both sides, and the lamp poles are initially lifted by the lamp pole clamping structures 4 and the interface grinding structure 3. At this time, the welding structure 5 is used to clamp and fix the lamp poles in cooperation with the lamp pole clamping structure 4, and the interface grinding structure 3 and the welding structure 5 are used to drive the lamp poles to rotate, and the interfaces of the lamp poles on both sides are ground. During the grinding process, the rust on the surface is cleaned by the interface grinding structure 3 and welded by the welding structure 5. The welds after welding are ground and cleaned again by the interface grinding structure 3 to ensure the cleanliness of the welds, reduce subsequent processing procedures, and improve production efficiency.

[0039] Embodiment 2

[0040] On the basis of the first embodiment, the present embodiment drives the auxiliary fixing assembly 52 to descend through the electric telescopic rod 51 and compresses the lamp pole through the U-shaped bracket 521 to clamp the lamp pole clamping structure 4 on the surface of the lamp pole to fix the lamp pole, and utilizes the interface grinding structure 3 and the lamp pole clamping structure 4 to cooperate with the friction wheel 522 to cause the lamp poles on both sides to rotate synchronously, and welds through the laser welding device 53 to avoid light, without manual fixation, reducing personnel participation, avoiding high welding temperature or sparks from causing damage to operators, and reducing unnecessary safety hazards.

[0041] Specifically, in order to realize the welding of two lamp poles and press and fix them during the welding process, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The welding structure 5 includes an electric telescopic rod 51 fixedly connected to the upper end of the support frame 2, the output end of the electric telescopic rod 51 penetrates the upper end of the support frame 2 and extends to the lower part of the inner surface of the support frame 2 and is fixedly connected with an auxiliary fixing component 52, and a laser welding device 53 is arranged at the lower end of the auxiliary fixing component 52; the auxiliary fixing component 52 includes a second connecting rod 520 fixedly connected to the output end of the electric telescopic rod 51, a second slide groove 525 is provided at the lower part of the outer surface of the second connecting rod 520, and a support rod 523 is slidably connected to the inner surface of the second slide groove 525, and a tension spring 1 524 fixedly connected to the bottom wall of the limiting groove provided by the second connecting rod 520 is fixedly connected to the middle part of the lower end of the support rod 523, and U-shaped brackets 521 are symmetrically fixedly connected to the left and right ends of the support rod 523, and arc panels 529 are symmetrically fixedly connected to the lower ends of the two U-shaped brackets 521.

[0042] It should be particularly noted that the above-mentioned electric telescopic rod 51 and laser welding device 53 are both conventional equipment in the prior art, wherein the electric telescopic rod 51 can extend and retract the piston rod when powered on, thereby driving the auxiliary fixing component 52 to operate, and the laser welding device 53 is a conventional laser welding equipment, which uses a laser head to emit a high-temperature laser to perform hot-melt welding on two objects. In the present invention, only the electric telescopic rod 51 and the laser welding device 53 are used to achieve the above functions, and their specific structure and operating principle are not described in detail.

[0043] When the electric telescopic rod 51 drives the U-shaped bracket 521 to descend, it will first pull the support rod 523 and the U-shaped bracket 521 on both sides thereof downward through the tension spring 524 until the arc panel 529 is tightly attached to the surface of the lamp pole. At this time, the tension spring 524 is stretched, and the U-shaped bracket 521 continues to descend, which will drive the laser welding device 53 and the weld of the lamp pole to gradually approach each other.

[0044] Further, in order to achieve the pressing of the lamp pole so that it is fixed in the left and right directions without affecting its forward and backward rotation, refer to Figure 3 and Figure 4 The inner surfaces of the two U-shaped brackets 521 are symmetrically provided with sliding grooves 528, the inner surfaces of the two sliding grooves 528 on the same U-shaped bracket 521 are slidably connected to the limiting blocks 527, the front and rear ends of the limiting blocks 527 are fixedly connected to the tension springs 526 fixedly connected to the bottom wall of the inner surface of the sliding grooves 528, and the inner surfaces of the two limiting blocks 527 on the same side are connected to the friction wheels 522 for common rotation.

[0045] After the support rod 523 is in close contact with the surface of the lamp pole, the friction wheel 522 and the lamp pole will also be in close contact with each other. When the interface grinding structure 3 drives the lamp pole to rotate, the friction wheel 522 prevents the support rod 523 from affecting the rotation of the lamp pole. At the same time, the friction force of the friction wheel 522 itself is also used to prevent the lamp pole from deviating left and right.

[0046] The purpose of setting the tension spring three 526 and the limit block 527 is that after the support rod 523 contacts the lamp pole, the friction wheel 522 can be tightly attached to the surface of the lamp pole under the action of the tension spring three 526.

[0047] Embodiment 3

[0048] On the basis of the second embodiment, the present embodiment utilizes the driving motor 32 to drive the grinding wheel 353 to rotate through the telescopic shaft 33 and the reversing gear set 34, and drives the driving wheel 351 and the cleaning wheel 352 to rotate through the transmission belt 354. The surface of the grinding wheel 353 is pressed against the surface of the lamp pole interface by the pressure of the support rod 523 and the cooperation of the compression spring 356 and the slider 355, and the rust spots on the interface are polished during the rotation. At the same time, the cleaning wheel 352 is used to clean the polished surface of the lamp pole to avoid rust residue remaining on the surface of the lamp pole.

[0049] Specifically, in order to achieve the initial grinding of the interface between the two lamp poles and the grinding of the welding slag after welding, refer to Figure 5 and Figure 6 The interface polishing structure 3 includes a support block 31 fixedly connected to the upper end of the table 1, a reversing gear set 34 is slidably connected to the right end of the support block 31, a telescopic shaft 33 is fixedly connected to the input end of the reversing gear set 34, the lower end of the telescopic shaft 33 passes through the upper end of the table 1 and extends to the lower end of the table 1 and is fixedly connected to a driving motor 32 fixedly connected to the lower end of the table 1, and the output end of the reversing gear set 34 is fixedly connected to a polishing and cleaning component 35 located in the inner cavity of the support block 31.

[0050] The driving motor 32 rotates to drive the support block 31 to rotate and mobilizes the grinding and cleaning component 35 to move through the conversion action of the reversing gear set 34. The welding slag polished and cleaned by the grinding and cleaning component 35 will fall into the support block 31. A door for cleaning the residue is opened on the front side of the support block 31.

[0051] Further, for grinding and welding slag treatment, see Figure 6 and Figure 7 The grinding and cleaning assembly 35 includes a driving wheel 351 symmetrically connected to the upper curved surface of the support block 31 for rotation front and rear, a grinding wheel 353 is rotatably connected to the middle part of the inner surface of the support block 31, and a cleaning wheel 352 is symmetrically connected to the inner surface of the support block 31 for rotation relative to the central axis of the grinding wheel 353. The lower parts of the outer surfaces on both sides of the central axis of the grinding wheel 353 are tightly attached to sliders 355 slidably connected to the inner surface of the support block 31 through vertical limit grooves, and the lower ends of the sliders 355 are fixedly connected to the compression springs 356 fixedly connected to the bottom wall of the inner cavity of the support block 31. The central axis surfaces of the driving wheels 351, the cleaning wheels 352 and the grinding wheels 353 on both sides are commonly wound and connected with a transmission belt 354, and the inner cavity of the support block 31 is provided with a tensioning wheel for tensioning the transmission belt 354, and one side of the central axis of the grinding wheel 353 is fixedly connected to the output end of the reversing gear set 34.

[0052] The reversing gear set 34 drives the grinding wheel 353 to rotate, and the transmission belt 354 wound on the outer surface of the grinding wheel 353 transmits the rotational power to the cleaning wheel 352 and the driving wheel 351. At the same time, the winding direction of the grinding wheel 353 is opposite to that of the driving wheel 351. While the driving wheel 351 drives the lamp pole to rotate by its own friction, the grinding wheel 353 rotates in the opposite direction to grind and remove slag at the interface of the two lamp poles. At the same time, under the pressure of the arc panel 529, the grinding wheel 353 compresses the compression spring 356. At this time, the lamp pole is supported by the driving wheels 351 on both sides, and its surface is in close contact with the grinding wheel 353.

[0053] At the same time, in order to ensure the transmission efficiency of the transmission belt 354, the inner wall of the support block 31 is also provided with many tensioning wheels for ensuring the winding angle of the transmission belt 354 and the driving wheel 351, the cleaning wheel 352, and the grinding wheel 353. Belt tensioning is a basic technical means in traditional transmission methods and is a mature technology. Some tensioning wheels are not shown in the figure.

[0054] Embodiment 4

[0055] On the basis of the third embodiment, the clamping drive assembly 45 drives the clamping arm assemblies 42 on both sides to move inwards and drive the arc-shaped clamping plate 44 to be in close contact with the surface of the lamp pole through the action of the gear 2 455, the gear 1 454 and the rack 2 459 when the support block 458 is pressed down by the gravity of the lamp pole and the pressure of the support rod 523, so as to make the roller 2 47 in close contact with the surface of the lamp pole, and the friction force of the roller 2 47 and the clamping action of the arc-shaped clamping plate 44 limit and fix the left and right directions of the lamp pole, so as to avoid the lamp pole from being offset during welding, causing the weld to rupture and affecting the welding effect;

[0056] At the same time, the pressure of the auxiliary fixing component 52 allows the lamp pole to further drive the lamp pole clamping structure 4 to operate, so that the lamp pole is tightly fitted with the interface grinding structure 3, thereby ensuring the grinding effect in the subsequent grinding process, and at the same time, during the welding process, it can also prevent the lamp pole from being clamped by the clamping arm component 42 under the action of the clamping arm component 42 and the clamping drive component 45, further preventing the lamp pole from jumping, falling off, etc. during welding and interface grinding, causing accidents, and also reducing the manual operation steps in the process of clamping and fixing the lamp pole, reducing the frequency of workers' participation, indirectly reducing the workers' contact with the lamp pole and welding equipment during the operation, and reducing safety hazards.

[0057] Specifically, in order to clamp and fix the lamp pole to prevent the lamp pole from moving left and right during welding, causing the interfaces on both sides to separate and affect the welding effect, refer to Figure 8 and Fig. 9The lamp pole clamping structure 4 includes a slide groove 41 symmetrically opened at the front and rear ends of the upper end of the table 1, and a clamping arm assembly 42 rotatably connected to the upper end of the table 1 is symmetrically arranged on the inner surfaces of the two slide grooves 41 on the same side, and an arc-shaped clamping plate 44 is arranged on the side of the clamping arm assembly 42 away from the rotating axis on the table 1. A clamping drive assembly 45 that passes through the table 1 is arranged at a position between the two arc-shaped clamping plates 44 on the same side of the upper end of the table 1, and a support rod 43 is fixedly connected to one end of the upper end of the table 1 away from the arc-shaped clamping plate 44 on the same side, and a plurality of rollers 47 are rotatably connected to the inner arc surface of the arc-shaped clamping plate 44, and a plurality of spring balls 46 are symmetrically arranged on the inner arc surface of the arc-shaped clamping plate 44.

[0058] The clamping drive assembly 45 is used to drive the clamping arm assembly 42 to drive the arc-shaped clamping plates 44 on both sides to approach each other so that the roller 2 47 provided on the arc-shaped clamping plates 44 is in close contact with the surface of the lamp pole;

[0059] In the initial state, the lamp pole is naturally overlapped on the upper side of the clamping drive assembly 45 and the clamping drive assembly 45 is initially pressed to drive the clamping arm assembly 42. At this time, the spring ball 46 on the inner arc surface of the arc clamping plate 44 overlaps the surface of the lamp pole, and the lamp pole is manually pushed inward until the lamp poles on both sides are in contact above the support block 31. The support rod 43 is rotatable, and the spring ball 46 is spherical, so the friction is small and will not affect the left and right movement of the lamp pole;

[0060] At this time, the electric telescopic rod 51 is started to drive the U-shaped bracket 521 to descend until the support rod 523 presses the lamp pole. The pressure of the support rod 523 on the lamp pole is transmitted to the clamping drive assembly 45, prompting the clamping drive assembly 45 to drive the arc clamping plate 44 to fit the surface of the lamp pole through the clamping arm assembly 42, so that the roller 2 47 is in contact with the surface of the lamp pole. The roller 2 47 has high friction and can effectively limit the left and right deviation of the lamp pole, but at the same time, the roller 2 47 also rotates, and will not affect the rotation of the lamp pole when the lamp pole is rotated by the driving wheel 351.

[0061] Further, in order to drive the arc-shaped clamping plate 44 to move inward to clamp and fix the lamp pole, refer to Fig.10 and Fig.11 The clamping arm assembly 42 includes a roller 423 slidingly connected to the inner surface of the slide groove 41, the central axis surface of the roller 423 is rotatably connected to a support arm 424 rotatably connected to the arc-shaped clamping plate 44 on the same side, the central axis surface of the roller 423 is rotatably connected to a connecting rod 422, the end of the connecting rod 422 away from the arc-shaped clamping plate 44 is rotatably connected to a support arm 421, the end of the support arm 421 away from the arc-shaped clamping plate 44 is rotatably connected to the upper end of the table 1, and the end of the support arm 421 close to the arc-shaped clamping plate 44 on the same side is rotatably connected to the middle part of the outer arc surface of the arc-shaped clamping plate 44.

[0062] When the rollers 423 on both sides move away from each other in the slide groove 41, the lower part of the outer arc surface of the arc clamping plate 44 will be pulled outward by the support arm 424, and at the same time, the connecting rod 422 is used to push the side of the support arm 421 connected to the arc clamping plate 44 to lift up so that the upper parts of the arc clamping plates 44 on both sides move inward, so that the arc clamping plate 44 is converted from inclined to vertical, and the inner arc surface of the arc clamping plate 44 tends to separate from the lamp pole;

[0063] When the rollers 423 on both sides approach each other in the slide groove 41, the lower part of the outer arc surface of the arc clamping plate 44 is pulled inward by the support arm 424, and at the same time, the connecting rod 422 is used to push the side of the support arm 421 connected to the arc clamping plate 44 to move downward so that the upper parts of the arc clamping plates 44 on both sides expand outward, so that the arc clamping plate 44 is converted from vertical to inclined, and the inner arc surface of the arc clamping plate 44 tends to fit the lamp pole;

[0064] Further, in order to drive the clamp arm assembly 42 to move and drive the arc clamp plate 44 to clamp the lamp pole, refer to Fig.11 and Fig.12 The clamping drive assembly 45 includes a supporting block 458, the lower end of the supporting block 458 is symmetrically fixedly connected to a supporting frame 453 which is slidably connected to a vertical sliding groove opened on the upper side of the table 1, one of the inner surfaces of one of the supporting frames 453 is fixedly connected to a rack 2 459, the rack 2 459 is meshed with a gear 2 455 which is rotatably connected to the adjacent surface of the shaft table 1 through a limit, the end of the gear 2 455 which is away from the supporting frame 453 where the rack 2 459 is installed is fixedly connected to a gear 1 454, the upper and lower parts of the outer surface of the gear 1 454 are symmetrically meshed with a rack 1 456, the ends of the two racks 1 456 which are away from each other are fixedly connected to a baffle 457 on the side close to the teeth, the baffle 457 is tightly attached to the central axis of the adjacent roller 1 423, the lower ends of the two supporting frames 453 are commonly fixedly connected to a bottom support plate 451, and the upper end of the bottom support plate 451 is fixedly connected to a tension spring 2 452 which is fixedly connected to the lower end of the table 1.

[0065] It should be specially noted that the above-mentioned gear 2 455 and gear 1 454 do not generate any movement in the vertical direction, and only rely on the engagement of gear 2 455 and rack 2 459 to generate rotation, thereby driving rack 1 456 to move horizontally. The installation methods are all mature conventional technologies, and are installed on the inner surface of the table 1 through a limit shaft or bearing. The specific installation method will not be displayed or elaborated in the present invention.

[0066] The support block 458 is under pressure to drive the gear 2 455 downward. At this time, the support frame 453 slides downward to prompt the rack 2 459 to drive the gear 2 455 to rotate. The rotation of the gear 2 455 drives the gear 1 454 to rotate, thereby driving the racks 1 456 on both sides to approach each other under the action of the gear 1 454, thereby pulling the rollers 1 423 on both sides inward through the baffle 457, and driving the arc clamping plate 44 to clamp the lamp pole;

[0067] But synchronously, when the support frame 453 descends, the bottom support plate 451 will pull the tension spring 2 452 to bear the force. After the lamp pole is welded and removed, the tension spring 2 452 will drive the bottom support plate 451 and the support frame 453 to reset, and the rack 1 456 and the baffle 457 will also reset synchronously under the action of the gear 1 454.
