Description

Technical Field

[0001] This utility model relates to the field of pipe welding technology, specifically to an automated welding equipment for plastic pipes. Background Technology

[0002] Plastic pipes, as an important component of chemical building materials, are widely accepted by users due to their superior performance, hygiene, environmental protection, and low consumption. The main types include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, polyethylene (PE) water supply pipes, and polypropylene PPR hot water pipes. In the process of using plastic pipes, welding machines are often required to perform hot-melt welding on the pipes.

[0003] Currently, there are many types of automated welding equipment. For example, a plastic pipe welding device with Chinese patent number CN202321203447.X includes a base and a welding frame. Two vertical plates are installed on the upper surface of the base. A groove is opened on one surface of the vertical plate. A screw sleeve is fixedly installed in the groove. A lead screw is threadedly connected to the screw sleeve. One end of the lead screw is rotatably connected to an adjusting plate. A mounting frame is fixedly installed on one surface of the adjusting plate. A motor is fixedly installed on the upper surface of the mounting frame. A bidirectional screw is fixedly connected to the output end of the motor. Two moving blocks are threadedly connected to the circumferential side of the bidirectional screw. A fixed block is fixedly connected to one surface of the moving blocks. This invention utilizes a lead screw, an adjusting plate, a bidirectional screw, and fixing blocks. The lead screw can move the adjusting plate to adjust and fix the pipe according to its length. When the bidirectional screw rotates, the two fixing blocks move to clamp and fix the pipe, eliminating the need for manual clamping. It offers high stability, high automation, and strong practicality. However, in actual use, although the device clamps the pipe through the lead screw and bidirectional screw, the clamping components use a rigid structure, which can only accommodate pipes of a fixed diameter. When changing specifications, manual disassembly and adjustment are required, and the support stability for long pipes is insufficient. Utility Model Content

A slide rod is fixedly installed inside each slot. A slider is slidably connected to the outer wall of each slide rod. A return spring is sleeved on the outside of each slide rod. A limiting guide block is provided on each slider and connected to the inner wall of the slot. An arc-shaped clamping block is fixedly connected to the end of each slider away from the limiting guide block.

[0007] Furthermore, the outer walls of the two second rectangular gears are respectively connected to the outer walls of the two first rectangular gears, and the connection between the two is a meshing connection, so as to achieve bidirectional synchronous drive.

[0008] Furthermore, one side of the reset spring is fixedly connected to the inside of the slot, and the other side is fixedly connected to the outer wall of the slider.

[0015] 1. This automated welding equipment for plastic pipes, through the setting of a clamping mechanism, first places the plastic pipe to be processed between the clamping frame and the fixed plate. Then, the clamping frame and the fixed plate achieve synchronous lifting and lowering through a threaded rod driven by a bidirectional servo motor, ensuring stable clamping of the pipe. Finally, through the cooperation of the sliding rod, slider and return spring in the slot, the arc-shaped clamping block can adapt to the pipe diameter. When the pipe diameter changes, the slider slides along the sliding rod and compresses the return spring. Through the arc surface tightly against the outer wall of the pipe, it achieves adaptation to different diameters. Thus, this mechanism not only clamps stably, but the design of the clamping frame also allows the equipment to place pipes of any length laterally, and the design of the four arc-shaped clamping blocks can effectively adapt to pipes of different diameters, making it highly practical.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 An automated welding device for plastic pipes in this embodiment includes a base 1, an equipment platform 2 fixedly installed on the base 1, two sliding grooves 3 are provided on the equipment platform 2, a clamping seat 4 is slidably connected inside each sliding groove 3, hydraulic telescopic devices 5 are provided on the left and right sides of the equipment platform 2, and a clamping mechanism 6 is provided above each clamping seat 4.

[0022] Each clamping mechanism 6 includes a clamping frame 601, the bottom of which is fixedly connected to the top of the clamping seat 4. The clamping frame 601 has a horizontally open design, supporting the placement of pipes of any length to adapt to different engineering needs. A set of bearings 602 is provided on the inner walls of both the front and rear sides of the clamping frame 601, with two bearings in each set. A threaded rod 603 extending to the outer top of the clamping frame 601 is fixedly connected to the inner wall of each bearing 602. A first rectangular gear 604 is provided at one end of each threaded rod 603 extending to the outer top of the clamping frame 601. A bidirectional servo motor 605 is fixedly mounted on the top of the clamping frame 601. A second rectangular gear 606 is provided at each of the two output ends of the bidirectional servo motor 605. The outer wall of the rectangular gear 606 is connected to the outer walls of the two first rectangular gears 604 respectively, and the connection between the two is a meshing connection to achieve bidirectional synchronous drive. The outer walls of the two threaded rods 603 are threadedly connected to movable blocks 607. Each movable block 607 is provided with a limiting guide plate 608 connected to the inner wall of the clamping frame 601. At the same time, the inner walls of the left and right sides of the clamping frame 601 are provided with limiting grooves adapted to the limiting guide plates 608, and the two are slidably connected. A fixed plate 609 is fixedly connected between the two movable blocks 607. Two slots 610 are provided on the close surfaces of the clamping frame 601 and the fixed plate 609. A sliding rod 611 is fixedly installed inside each slot 610. The outer wall of each sliding rod 611 is slidably connected to the fixed plate 609. A slider 612 is dynamically connected, and a return spring 613 is sleeved on the outside of each slider 611. One side of the return spring 613 is fixedly connected to the inside of the slot 610, and the other side is fixedly connected to the outer wall of the slider 612. Each slider 612 is provided with a limiting guide block 614 connected to the inner wall of the slot 610. At the same time, the inner wall of each slot 610 is provided with a limiting groove that matches the limiting guide block 614, and the two are slidably connected. An arc-shaped clamping block 615 is fixedly connected to the end of each slider 612 away from the limiting guide block 614. Thus, the arc-shaped clamping block 615 forms an elastic clamping structure through the slider 611, slider 612 and return spring 613. First, the plastic tube to be processed is placed in the clamping frame. Between clamping frame 601 and fixing plate 609, clamping frame 601 and fixing plate 609 are synchronously raised and lowered by threaded rod 603 driven by bidirectional servo motor 605, ensuring stable clamping of pipe. Finally, through the cooperation of sliding rod 611, slider 612 and return spring 613 in slot 610, the arc-shaped clamping block 615 can adapt to the pipe diameter. When the pipe diameter changes, slider 612 slides along sliding rod 611 and compresses return spring 613. The arc-shaped surface of the arc-shaped clamping block 615 is in close contact with the outer wall of the pipe, achieving adaptation to different diameters. Thus, this mechanism not only clamps stably, but the design of clamping frame 601 also allows the device to place pipes of any length laterally, and the design of four arc-shaped clamping blocks 615 can effectively adapt to pipes of different diameters.It is quite practical.

[0023] In the implementation of the case, the movable ends of the two hydraulic telescopic devices 5 are fixedly connected to the outer walls of the two clamping seats 4 respectively. This design allows the workers to achieve the purpose of automating the connection of pipe materials by controlling the hydraulic telescopic devices 5 on both sides.

[0024] In the implementation of the case, an equipment mounting frame 7 is fixedly installed directly above the equipment platform 2. A welding device 8 is installed on the equipment mounting frame 7. The welding device 8 includes a hot melt welding gun and a temperature sensor. The temperature sensor is electrically connected to the controller 9 to realize closed-loop control of the welding temperature.

[0025] In the implementation of the case, a controller 9 is provided on the front side of the base 1. The controller 9 is electrically connected to the electronic components in this patent through wires, which makes it convenient to operate the controller 9 to control the operation of the electronic components.

[0026] When implementing this procedure, please follow these steps:

[0027] 1) First, place the plastic pipe to be processed between the clamping frame 601 and the fixing plate 609;

[0028] 2) Then the clamping frame 601 and the fixing plate 609 are driven by the bidirectional servo motor 605 to achieve synchronous lifting and lowering of the threaded rod 603, ensuring stable clamping of the pipe.

[0029] 3) Then, through the cooperation of the slide rod 611 and slider 612 within the slot 610 and the return spring 613, the arc-shaped clamping block 615 can adapt to the diameter of the pipe.

[0030] 4) Finally, when the pipe diameter changes, the slider 612 slides along the slide rod 611 and compresses the reset spring 613. The arc-shaped clamping block 615 is in close contact with the outer wall of the pipe to achieve the adaptation of different diameters.

[0031] In summary, this automated welding equipment for plastic pipes, by setting up a clamping mechanism 6, first places the plastic pipe to be processed between the clamping frame 601 and the fixed plate 609. Then, through the linkage of the bearing 602, threaded rod 603, first rectangular gear 604, bidirectional servo motor 605, second rectangular gear 606, movable block 607, and limit guide plate 608, the fixed plate 609 can be stably moved towards the inner top wall of the clamping frame 601. At this time, the plastic pipe placed between the clamping frame 601 and the fixed plate 609 can be fixed vertically. Finally, through the cooperation of the sliding rod 611, the slider 612 and the return spring 613 in the slot 610, the arc-shaped clamping block 609 is fixed vertically. The 15-inch adjustable pipe diameter allows the slider 612 to slide along the slide rod 611 and compress the return spring 613 when the pipe diameter changes. The curved surface of the arc-shaped clamping block 615 is in close contact with the outer wall of the pipe, thus achieving adaptation to different diameters. As a result, the mechanism not only provides stable clamping, but the design of the clamping frame 601 also allows the device to place pipes of any length laterally. Furthermore, the design of the four arc-shaped clamping blocks 615 can effectively adapt to pipes of different diameters, making it highly practical. This solves the problem that although the device uses a lead screw and a bidirectional screw to clamp the pipe, the clamping components adopt a rigid structure, which can only adapt to pipes of a fixed diameter. When changing specifications, manual disassembly and adjustment are required, and the support stability for long pipes is insufficient.
