Description

Technical Field

[0001] This utility model relates to the field of pipeline welding technology, and in particular to a water supply pipe welding device. Background Technology

[0002] Water supply pipes are pipes that guide water flow to a designated location. They are divided into metal pipes, composite pipes, and plastic pipes. During production and processing, due to the size of the production equipment, the pipe forming length is relatively short. In actual use, it is necessary to weld the sections of metal pipes together using a welding device to form a long pipe, which facilitates the laying and use of the pipe.

[0003] However, existing welding equipment can only fix metal pipes together during use, and cannot drive them to rotate. This requires manual operation of the welding machine around the weld seam, which can easily affect the efficiency and quality of water supply pipe welding, and has certain limitations.

[0004] To address this issue, those skilled in the art have provided a water supply pipe welding device to solve the problems mentioned in the background section. Utility Model Content

The two ends of the two rotating shafts are rotatably connected to the outer walls of the two pairs of blocks respectively. At the same time, the two pairs of sliders slide onto the outer walls of the two pairs of guide rods respectively.

[0011] As a preferred technical solution of this utility model, worm gears are fixed inside the two square covers and on the outer wall of the rotating shaft. Worms are rotatably installed on the inner bottom surface of the two square covers. One end of each worm extends to the outer top surface of the square cover and is fixed with a knob.

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] In the attached diagram, all identical reference numerals refer to the same components.

[0030] like Figure 1-4 As shown, this utility model provides a water supply pipe welding device, including a base plate 1. The base plate 1 is fixed in a designated area by turning the positioning bolts. Support plates 101 are fixed at both ends of the outer top surface. Sleeves 102 for placing water supply pipes are rotatably installed inside the two support plates 101. The two ends of the two sleeves 102 extend to the outer walls of the left and right sides of the support plate 101 respectively. Two sections of water pipes to be welded are placed inside the sleeves 102 in sequence, and the welding ends of the two water pipes are brought together. Limiting components 2 for clamping and fixing the water supply pipes are provided on the corresponding side of the two sleeves 102.

[0031] The limiting assembly 2 includes a square cover 201 fixedly installed on the outer peripheral sidewall of two sleeves 102 on corresponding sides. A rotating shaft 202 is rotatably installed inside each of the two square covers 201. A worm gear 208 is fixed inside each of the two square covers 201 and on the outer wall of the rotating shaft 202. A worm 209 is rotatably installed on the inner bottom surface of each of the two square covers. One end of each worm 209 extends rotatably to the outer top surface of the square cover 201 and is fixed with a knob 2. 10. The two worm gears 208 and worm 209 are meshed together. After the water pipe to be welded is placed inside the two sleeves 102, the knob 210 is turned to drive the worm 209 to rotate inside the square cover 201, thereby driving the worm gears 208 to drive the rotating shaft 202 to rotate (after the worm 209 has finished rotating, the shaft locking device installed on the outer top surface of the square cover 201 locks the worm 209 to prevent self-rotation).

[0032] Furthermore, the two ends of the two rotating shafts 202 extend to the front and rear outer walls of the square cover 201. The square cover 201 has oppositely oriented threads on both ends of the outer periphery of the two rotating shafts 202. Slider blocks 203 are threaded onto both ends of the two rotating shafts 202. The interiors of the two sleeves 102 are symmetrically equipped with arc-shaped clamping blocks 204 (the clamping ends of the two pairs of arc-shaped clamping blocks 204 are equipped with anti-slip pads to increase the clamping resistance against the outer periphery of the water pipe and reduce the possibility of the water pipe moving). Round rods 205 are fixed to the bottom of the corresponding outer walls of the two pairs of sliders 203. One end of each pair of round rods 205 slides into the interior of the two sleeves 102 and is fixed to the two pairs of arc-shaped clamping blocks 204. Guide rods 206 are fixed to the front and rear outer walls of the two square covers 201 (the guide rods 206 assist in the relative movement of the sliders 203). (More stable), two pairs of guide rods 206 have square blocks 207 fixed on their opposite outer walls. The two ends of the two rotating shafts 202 are rotatably connected to the outer walls of the two pairs of square blocks 207. At the same time, the two pairs of sliders 203 are slidably sleeved on the outer walls of the two pairs of guide rods 206. When the rotating shaft 202 rotates, the opposite direction of the threads drives the sliders 203 to move relative to each other, thus allowing the round rod 205 to move synchronously with the arc-shaped clamp 204, thereby clamping and fixing the two sides of the water pipe inside the sleeve 102. This facilitates stability during subsequent welding and rotation, improving the efficiency and quality of water pipe welding. (The circumferential diameter of the rotating shaft 202 and guide rod 206 during rotation is smaller than the diameter between the rotating shaft 302 and the sleeve 102, so the rotating shaft 202 and guide rod 206 will not come into contact or collide with the rotating shaft 302 during rotation.)

[0033] Furthermore, a power assembly 3 for driving the two sleeves 102 to rotate synchronously is provided on the outer top surface of the base plate 1. The power assembly 3 includes a square cover 301 fixed at the center of the outer top surface of the base plate 1. A rotating shaft 302 is rotatably mounted inside the square cover 301. A worm gear 303 is fixed on the outer wall of the rotating shaft 302. The two ends of the rotating shaft 302 pass through the square cover 301 and extend rotatably to the opposite outer side walls of the two support plates 101. Gears 304 are fixedly mounted on the opposite outer side walls of the two support plates 101 and on the outer peripheral side walls of the rotating shaft 302. External gear rings 305 are fixedly mounted on the opposite outer side walls of the two sleeves 102. The two gears 304 and the two external gear rings 305 are meshed with each other. A worm is rotatably mounted inside the square cover 301 and below the worm gear 303. A drive motor 307 is fixedly installed on the rear outer wall of the square cover 301. One end of the worm gear 306 extends rotatably to the rear outer wall of the square cover 301 and is fixedly connected to the output end of the drive motor 307. The worm wheel 303 and the worm gear 306 are meshed together. The drive motor 307 is controlled and started to drive the worm gear 306 to drive the worm wheel 303 to rotate inside the square cover 301. This causes the rotating shaft 302 to drive the two gears 304 to rotate synchronously. Then, under the meshing connection characteristics of the gears 304, the two external gear rings 305 are driven to carry the two sleeves 102 to rotate synchronously and in the same direction on the support plate 101. This causes the water pipe to be welded to rotate to adjust the welding position, so that the welding machine 405 can perform circumferential welding around the weld seam of the water pipe, thereby improving the efficiency and quality of water pipe welding.

[0034] Furthermore, a U-shaped frame 103 is fixed to the outer top surface of both support plates 101. A welding assembly 4 is provided on the outer top surface of the U-shaped frame 103. The welding assembly 4 includes an electric slide rail 401 fixedly installed on the outer top surface of the U-shaped frame 103. A U-shaped frame 402 is provided on the outside of the U-shaped frame 103. The inner top surface of the U-shaped frame 402 is fixedly connected to the moving end of the electric slide rail 401 by bolts (the bolt connection method facilitates disassembly and assembly). An electric push rod 403 is fixedly installed on the inner bottom surface of the U-shaped frame 402. The output end of the electric push rod 403 slides to the outer bottom surface of the U-shaped frame 402 and is fixed with a connecting plate 404. A welding machine 405 is fixed to the outer bottom surface of the connecting plate 404 by bolts (the bolt connection method facilitates the connection of the welding machine 405). (For disassembly, assembly, maintenance and replacement), both ends of the top surface of the connecting plate 404 are fixed with sliding rods 406. One end of each sliding rod 406 extends slidably inside the loop frame 402. After the two sections of water pipe to be welded are attached to each other, the controller controls and starts the electric slide rail 401 to move laterally, thereby driving the loop frame 402 to move the welding machine 405 to the weld. The position detector installed on the base plate 1 detects whether the welding head of the welding machine 405 is aligned with the weld. Then the position detector transmits a signal to the controller, which then controls and starts the electric push rod 403 to move the welding machine 405 downward, so that the welding head of the welding machine 405 contacts the weld of the water pipe, and starts the welding machine 405 to perform the welding operation.

[0035] The working principle of this utility model is as follows: When using it, first insert the water pipe to be welded into the sleeve 102, then turn the knob 210 to drive the rotating shaft 202 to rotate, thereby driving the slider 203 to move relative to the arc-shaped clamp 204, clamping and fixing both sides of the water pipe. Then, follow the same operation to insert another section of water pipe into the sleeve 102, and make the welding ends of the two sections of water pipe fit together. Then, follow the above operation to fix the other section of water pipe.

[0036] Simultaneously, the electric slide rail 401 is activated to drive the loop frame 402 to move the welding machine 405 to the weld seam. Then, the electric push rod 403 is activated to move the welding machine 405 downward, so that the welding head comes into contact with the weld seam of the two water pipes. Finally, the welding machine 405 is activated to perform the welding operation.

[0037] At the same time, the drive motor 307 is started to drive the rotating shaft 302 to drive the two gears 304 to rotate, thereby driving the two external gear rings 305 to carry the two sleeves 102 to rotate synchronously and in the same direction on the support plate 101. This allows the two sections of water pipe to be welded to rotate to adjust the welding position, making it easier for the welding machine 405 to perform welding operations around the weld seam of the water pipe, thus improving the efficiency and quality of water pipe welding.

[0038] It should be noted that the position detector, welding machine 405, and electric slide rail 401 are all existing technology devices, and their working principles and usage methods will not be specifically described in this article. Also, all electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the art, so the control method and circuit connection will not be explained in detail.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
