Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a street lamp pole head welding device and method with a clamping and adjusting structure. Background Art

[0002] There are many types of street lamps, including high pole street lamps, road lamps, monitoring poles, new special-shaped tube street lamps, stainless steel landscape lamps, sculpture landscape lamps, garden lamps, cast aluminum garden lamps, cast iron garden lamps, etc. In the production of lamp poles, it is often necessary to splice the heads of two lamp poles and then weld them to fix them. They can be freely spliced ​​according to actual use requirements. Therefore, in the production process of lamp poles, welding equipment is needed to assist welding production and reduce the difficulty of welding.

[0003] A clamping and adjusting device for welding street light pole heads disclosed in a patent application with reference publication number CN106078038A can dock two street light poles, and the rotary adjustment tube can realize horizontal rotation adjustment around the guide tube. The rotary adjustment tube can facilitate horizontal rotation adjustment of the rotating plate, and the rotating plate can facilitate installation of the welding machine, and the welding machine can facilitate welding of two street light poles.

[0004] The above welding adjustment device can complete the clamping and fixing of the lamp pole through the first butt joint tube and the second butt joint tube, but cannot effectively complete the multi-directional clamping and fixing of the lamp pole, so that the clamping effect of the lamp pole is not ideal, and the problem of deviation is easy to occur in the subsequent welding, which affects the welding quality and reduces the quality of the lamp pole;

[0005] At the same time, during the welding process, the above-mentioned welding adjustment device cannot effectively complete the mobile welding around the joint of the lamp pole, which increases the difficulty of welding and cannot ensure the stable progress of the welding work.

[0043] Among them, electrical components such as the walking motor 22, the electric slide 7, the No. 1 cylinder 10, the No. 2 cylinder 23, the No. 3 cylinder 26, the grinding motor 29, the cleaning motor 40 and the welding gun 24 are all connected to switches through wires, and the switches are electrically connected to the controller. The specific structure of the controller is not limited. An absolute encoder is installed on the walking motor 22 for accurately positioning the walking motor 22.

[0044] Embodiment 2: Based on the clamping mechanism provided in Embodiment 1, this embodiment provides a further technical solution for the clamping mechanism.

[0045] like Figures 2 to 5 As shown, each clamping mechanism includes two symmetrically arranged slideways 4, and the side walls of the two slideways 4 are provided with a plurality of positioning holes 5 in parallel. A plurality of supporting members 6 are slidably engaged with the two slideways 4, and a clamping member is installed on the processing table 1 near the side of the annular frame 3, and the lamp pole body 2 is clamped and fixed by the clamping member and the plurality of supporting members 6;

[0046] In the embodiment of the present invention, each support member 6 includes a slide seat 61 that is slidably engaged on two slideways 4, and a telescopic member 62 is installed in the middle position of the upper surface of the slide seat 61. The telescopic member 62 uses an electric telescopic rod, a manual telescopic rod, a gear 21, and a rack telescopic rod to complete the lifting action. A concave seat 63 is installed on the top of the telescopic member 62, and a No. 1 roller 64 is rotatably installed at the bottom of the concave seat 63. A No. 2 roller 65 is rotatably installed on both sides of the inner wall of the concave seat 63 through a bracket. The No. 1 roller 64 and the No. 2 roller 65 guide the lamp pole body 2 to rotate. Positioning screws 66 are inserted through threaded engagement on both sides of the slide seat 61, and a hand wheel is installed at the tail of the positioning screw 66. The front end of the positioning screw 66 is correspondingly inserted into the positioning hole 5;

[0047] It is worth noting that when the lamp pole body 2 is clamped and fixed: by providing a clamping mechanism, the lamp pole body 2 is moved to a plurality of support members 6 accordingly, so that the lamp pole body 2 can be supported at multiple points, ensuring the stability of the lamp pole body 2, and the rotation of the lamp pole body 2 is guided by the No. 1 rotating roller 64 and the No. 2 rotating roller 65, so that the lamp pole body 2 can be stably moved, which is convenient for the clamping member to complete the movement and adjustment of the position of the lamp pole body 2, and at the same time, the support member 6 can be adjusted, which is convenient for active adjustment according to the lamp pole body 2 of different lengths. Specifically, it is only necessary to rotate the positioning screw 66 so that the positioning screw 66 is moved out of the positioning hole 5. At this time, the slide 61 can be moved on the two slideways 4 to complete the position adjustment. After the adjustment is completed, it is only necessary to insert the positioning screw 66 into the positioning hole 5 to complete the limiting. At the same time, the height of the slide 61 can be adjusted by the telescopic member 62, which is convenient for fine-tuning according to the lamp pole body 2 of different sizes.

[0048] In the embodiment of the present invention, the clamping member includes an electric slide 7 installed between two slideways 4, a sliding member 8 is installed at the output end of the electric slide 7, and the sliding member 8 is correspondingly slidably engaged with the two slideways 4, and a ring member 9 is installed on the sliding member 8, and the ring member 9 is concentrically arranged with the ring frame 3, and two No. 1 cylinders 10 are symmetrically installed on the top and bottom of the ring member 9, and pressure members 11 are installed at the output ends of the two No. 1 cylinders 10, and two guide rods are symmetrically installed on the backs of the two pressure members 11, and the two guide rods are correspondingly slid through the ring member 9, and the pressure member 11 contacts with the lamp pole body 2 to complete the restriction, and two manual slides 12 are symmetrically penetrated on the left and right sides of the ring member 9, and at the output end of the manual slide 12 An air chamber 13 is installed, and the top of the air chamber 13 is open. A piston member 14 is slidably installed in the air chamber 13. The piston member 14 consists of a piston block and a piston rod. The piston block is slidably engaged in the air chamber 13, and a track matching the piston block is provided in the air chamber 13, so that the piston block can stably move up and down in the air chamber 13. The piston rod is fixedly installed in the middle position of the piston block, and the piston rod is fixedly connected to the top of the pressure block. A pressure plate 15 is installed on the top of the piston member 14, and a No. 1 pipe 16 is installed on one side of the bottom of the air chamber 13, and a No. 1 spring 17 is installed between the piston member 14 and the bottom of the air chamber 13, and the No. 1 spring 17 is used to pull the piston member 14 to reset toward the air chamber 13;

[0049] It should be noted that: when the lamp pole body 2 is moved, the No. 1 cylinder 10 is started to push the pressing piece 11 to move toward the lamp pole body 2 to fit and complete the reinforcement. In this path, the arc plate 112 first contacts the surface of the lamp pole body 2, and then the arc plate 112 shrinks and moves into the arc cavity 111, so that the No. 2 spring 113 shrinks, and the gas in the arc cavity 111 is sent out through the No. 2 pipe 114 and sent into the No. 1 pipe 16 through the hose, so that the piston 14 overcomes the No. 1 spring 113 in the air chamber 13. 7 pulls upward, driving the pressing plate 15 to fit and contact the side wall of the lamp pole body 2 to complete the follow-up pressing, thereby completing the multi-directional fixation of the lamp pole body 2, avoiding the problem of offset, and facilitating the subsequent welding process. Subsequently, the No. 1 cylinder 10 is reset, and the arc plate 112 is moved out of the arc cavity 111, so that the pressing plate 15 is reset and separated from the lamp pole body 2. At the same time, the electric slide 7 can be used to fine-tune the position of the clamp and the lamp pole body 2, and can complete the adaptation process with the welding mechanism, reducing the difficulty of processing;

[0050] Among them, each pressing piece 11 includes an arc-shaped cavity 111 with an open bottom, an arc-shaped plate 112 is installed in the arc-shaped cavity 111 in a sliding and sealing manner, and a sliding area cooperating with the arc-shaped plate 112 is arranged on the inner wall of the arc-shaped cavity 111. The sliding area slides and engages with the arc-shaped plate 112 correspondingly, and can complete active restriction on the arc-shaped plate 112. At the same time, a certain amount of gas is injected into the arc-shaped cavity 111, which is beneficial to subsequent driving operations. A plurality of No. 2 springs 113 are evenly distributed between the arc-shaped plate 112 and the bottom of the arc-shaped cavity 111. The plurality of No. 2 springs 113 are used to push the arc-shaped plate 112 out of the arc-shaped cavity 111, and a No. 2 pipe 114 is installed on the back of the arc-shaped cavity 111. The No. 1 pipe 16 is connected to the No. 2 pipe 114 through a hose. An inner gear ring 18 is hidden in the middle position of the inner wall of the annular frame 3. Both side walls of the frame 3 are provided with guide rails 19, which are composed of a circular rail 191 and a transition rail 192, and the length of the transition rail 192 corresponds to the distance between the No. 1 shift seat 20 and the No. 2 shift seat 32 and completes the distance compensation, that is, when the welding gun 24 welds from the welding start point to the welding end point, the trigger rod 35 is reset from the transition rail 192 to the circular rail 191, and the circular rail 191 is provided on the side wall of the annular frame 3, and a notch is provided on the circular rail 191, and the transition rail 192 is provided on the side wall of the annular frame 3 and is located above the circular rail 191, and one end of the transition rail 192 is connected to the notch at one end of the circular rail 191, and the other end of the transition rail 192 is connected to the circular rail 191, and the transition rail 192 and the circular rail 191 are connected at an inclined transition.

[0051] It is worth noting that: by providing a guide track 19, the guide track 19 is composed of a circular track 191 and a transition track 192. Under normal circumstances, the follow-up cleaning unit follows the trigger rod 35 and is hidden in the starting section of the circular track 191. During specific welding, the cleaning roller 39 is first started for cleaning processing. At the same time, the cleaning roller 39 is freely used according to actual processing requirements. At this time, the No. 1 moving seat 20 and the No. 2 moving seat 32 move synchronously in the preset direction. First, the welding gun 24 is not started. After waiting to move to the cleaning starting point of the cleaning roller 39, the welding gun 24 is started for welding processing, so as to obtain a good welding state. Subsequently, the subsequent cleaning and welding processing can be completed under the control of the travel motor 22. Due to the distance difference between the welding gun 24 and the cleaning roller 39, in order to avoid the interference of the cleaning roller 39 on the welding of the welding gun 24, when the trigger rod 35 on the follow-up cleaning unit moves to the end of the circular track 191, that is, the starting section of the transition track 192, the trigger rod 35 enters In the transition track 192, since the transition track 192 is farther from the center of the annular frame 3 than the circular track 191, the trigger rod 35 pulls the concave frame 34 upward, so that the cleaning roller 39 moves upward synchronously and separates from the lamp pole body 2, avoiding the cleaning roller 39 from affecting the welding position and damaging the cleaning roller 39. Then the trigger rod 35 continues to move in the transition track 192 until its end. At this time, the welding gun 24 reaches the end of the welding. Then the trigger rod 35 is reset to the circular track 191 via the No. 3 spring 36 to complete the stable welding of the lamp pole body 2. Through the cooperation of the transition track 192, the distance difference between the welding gun 24 and the cleaning roller 39 can be compensated. The distance difference is the distance that the welding gun 24 moves from the initial starting point to the cleaning starting point of the cleaning roller 39 in the early stage, making the welding process more stable. After the welding is completed, the travel motor 22 is controlled in reverse to drive the trigger rod 35 to reset to the starting section of the circular track 191, waiting for subsequent welding work to be carried out.

[0052] Embodiment 3: Based on the welding mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the welding mechanism.

[0054] It is worth noting that when the lamp pole body 2 is mobile welded: by providing a mobile welding unit, after the end surface pretreatment of the lamp pole body 2 is completed, the No. 3 cylinder 26 is controlled to reset, and then the electric slide 7 is started to pull the lamp pole body 2 to move to complete the splicing, and then the travel motor 22 is started again, and the gear 21 is meshed with the inner gear ring 18, so that the No. 1 moving seat 20 moves. Since the No. 1 moving seat 20 and the No. 2 moving seat 32 are connected through the bracket, the No. 2 moving seat 32 follows the No. 1 moving seat 20 to move. First, the telescopic arm 37 is controlled to complete the telescopic action, so that the cleaning roller 3 9 contacts the joint of the lamp pole body 2, and then starts the cleaning motor 40, so that the cleaning roller 39 rotates to complete the cleaning of the surface of the lamp pole body 2, avoiding the problem of impurities in the welding place affecting the welding, and improving the welding quality. After that, during the movement of the No. 2 moving seat 32, the cleaning roller 39 and the welding gun 24 are synchronously moved, so that the cleaning roller 39 completes the cleaning of the joint of the lamp pole body 2, and the welding gun 24 completes the circumferential welding of the joint of the two lamp pole bodies 2, and the No. 2 cylinder 23 can complete the free control of the position of the welding gun 24, thereby improving the welding accuracy;

[0056] It is worth noting that: when the lamp pole body 2 is pre-processed: an end face grinding unit is provided, and the clamping part and the lamp pole body 2 thereon are driven to move toward the annular frame 3 via the electric slide 7, and then the No. 3 cylinder 26 is started to push the assembly seat 27 to move toward the lamp pole body 2, and the grinding shaft 28 is moved to the edge of the lamp pole body 2, and the No. 1 grinding area 30 or the No. 2 grinding area 31 is brought into contact with the lamp pole body 2, and then the grinding motor 29 is started to drive the grinding shaft 28 to rotate, and the end face of the lamp pole body 2 is polished via the grinding shaft 28 to ensure that the lamp pole body The consistency of the end face of the lamp body 2 is avoided to cause interference to the welding. The No. 1 grinding area 30 and the No. 2 grinding area 31 are controlled by the No. 3 cylinder 26 to contact with the end face of the lamp pole body 2, which is convenient for the technicians to control the grinding accuracy.
