Description

Technical Field

[0001] This utility model relates to the field of PE pipe fitting welding technology, and in particular to a PE pipe fitting welding device applicable to multiple specifications. Background Technology

[0002] PE pipe welding refers to the process of connecting polyethylene pipes and their fittings together by heating to form a continuous, sealed pipeline system. This connection method is widely used in water supply, gas transmission, sewer systems, agricultural irrigation and other fields because PE material has good corrosion resistance, flexibility and a long service life.

[0003] A PE pipe fitting welding device, with announcement number CN222223502U, includes a base, guide rail, slider, and heating plate. A support with a through hole is fixedly installed on the slider, and symmetrically arranged sleeves are fixedly installed on the support. A limiting component for limiting the PE pipe fitting is installed inside the sleeve. A bracket is fixedly installed on the base, and a hydraulic cylinder is fixedly installed on the bracket. A traction rod is fixedly connected to the output end of the hydraulic cylinder. This device, driven by a motor, allows two limiting plates to limit the PE pipe fitting from both sides. By moving the limiting plates, different specifications of PE pipe fittings can be limited, thus reducing the operator's workload. However, because PE pipe fittings have PE bends at different angles, this device cannot adjust the angle of the fixed limiting plates and the support, making it inconvenient to perform hot-melt welding on PE bends of different angles. It is not flexible enough and is relatively inconvenient to use.

[0004] Therefore, it is necessary to design a welding device for PE pipe fittings that can be adjusted according to the angle of the PE bend, so as to facilitate hot-melt welding of PE bends at different angles and be applicable to multiple specifications. Utility Model Content

[0005] To overcome the shortcomings of existing technology, which cannot adjust the angle of the fixing limit plate and support of PE pipe fittings due to the different angles of PE bends, making it inconvenient to perform hot-melt welding on PE bends of different angles and lacking flexibility in use, this utility model provides a PE pipe fitting welding device that can be adjusted according to the angle of the PE bend, facilitating hot-melt welding on PE bends of different angles and offering flexibility in use for multiple specifications.

[0006] Technical Solution: A welding device for PE pipe fittings applicable to multiple specifications includes a base, a rotating frame, a sliding rod, a slide rail, a worm gear, a worm wheel, a lead screw, a first motor, a slider, and a clamping assembly. The rotating frame is rotatably connected to the center of the base. Sliding rods are connected to both sides of the front of the rotating frame. A slide rail is connected to the right side of the base, and the sliding rods slide in cooperation with the slide rail. A worm gear is rotatably connected to the front center of the base. A worm wheel is connected to the lower front side of the rotating frame, and the worm wheel meshes with the worm gear. A first motor is connected to the right side of the base and the left side of the rotating frame. The first motor is electrically connected to a processor through a control module. A lead screw is connected to the output shaft of each first motor, and a slider is threadedly connected to the lead screw. The base is threadedly connected to its adjacent slider, and the rotating frame is also threadedly connected to its adjacent slider. Each slider is equipped with a clamping assembly capable of centering and clamping PE pipe fittings of different sizes.

[0007] Furthermore, it is particularly preferred that the slide rail has an arc-shaped structure.

[0008] Furthermore, it is particularly preferred that the clamping assembly includes a mounting plate, a rotating disk, a second motor, gears, and clamping blocks. The mounting plate is connected to each slider, and the rotating disk is rotatably connected to the side of the mounting plate that is close to each other. The second motor is connected to the front of each mounting plate. The second motor is electrically connected to the processor through a control module. Gears are connected to the output shaft of each second motor. A large gear ring is provided on the outer side of each rotating disk. The large gear ring meshes with the adjacent gears. Multiple clamping blocks are slidably connected to each mounting plate. The clamping blocks slide with the adjacent rotating disks.

[0009] Furthermore, it is particularly preferred that the sides of the clamping blocks that are close to each other are all arc-shaped structures.

[0010] Furthermore, it is particularly preferred that a knob is also included, with the knob connected to the right side of the worm gear.

[0011] In addition, it is particularly preferable that the knob has anti-slip texture.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention rotates the worm gear by holding the knob, and the worm gear and worm wheel mesh with each other, driving the rotating frame to rotate, so that the slide bar slides along the slide rail, driving the PE straight pipe clamped between the clamping blocks to rotate, so that the welding point of the PE straight pipe is aligned with the welding point of the PE bend, achieving the effect of being able to adjust according to the angle of the PE bend, facilitating the hot melt welding of PE bends at different angles, and making it flexible in use.

[0013] 2. This utility model starts the second motor, which drives the gear to rotate. The gear meshes with the large gear ring, causing the rotating disk to rotate on the mounting plate. This causes the clamping block to move inward along the rotating disk to clamp and fix the PE pipe fitting. This achieves the effect of centered clamping of PE pipe fittings of different sizes, which is convenient for welding PE pipe fittings of different sizes. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] A welding device for PE pipe fittings applicable to multiple specifications, such as Figures 1-3 As shown, the assembly includes a base 1, a rotating frame 2, a slide rod 21, a slide rail 3, a worm gear 4, a worm wheel 5, a lead screw 6, a first motor 61, a slider 7, a knob 13, and a clamping assembly. The rotating frame 2 is rotatably connected to the center of the base 1. Slide rods 21 are connected to both sides of the front of the rotating frame 2. A slide rail 3, which has an arc-shaped structure for easy guidance, is connected to the right side of the base 1. The slide rods 21 slide in cooperation with the slide rail 3. A worm gear 4 is rotatably connected to the front center of the base 1. A worm wheel 5 is connected to the lower front side of the rotating frame 2. The worm wheel 5... The worm gears 4 mesh with each other. The right side of the base 1 and the left side of the rotating frame 2 are both connected to the first motor 61. The first motor 61 is electrically connected to the processor through the control module. The output shaft of the first motor 61 is connected to the lead screw 6. The lead screw 6 is threadedly connected to the slider 7. The base 1 is threadedly connected to its adjacent slider 7. The rotating frame 2 is also threadedly connected to its adjacent slider 7. The right side of the worm gear 4 is connected to the knob 13. The knob 13 is provided with anti-slip texture for easy gripping. The slider 7 is provided with clamping components.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the clamping assembly includes a mounting plate 8, a rotating disk 9, a second motor 10, gears 11, and clamping blocks 12. Mounting plates 8 are connected to the sliders 7. Rotating disks 9 are rotatably connected to the adjacent sides of the mounting plates 8. Second motors 10 are connected to the front of each mounting plate 8. Each second motor 10 is electrically connected to the processor via a control module. Gears 11 are connected to the output shaft of each second motor 10. Large gear rings are provided on the outer side of each rotating disk 9, and these large gear rings mesh with adjacent gears 11. Three clamping blocks 12 are slidably connected to each mounting plate 8. The adjacent sides of the clamping blocks 12 are arc-shaped to facilitate clamping PE pipe fittings. Each clamping block 12 slides in cooperation with the adjacent rotating disk 9.

[0022] When using this device, first place the base 1 in the PE pipe welding area, then place the two PE pipes between the clamping blocks 12. The processor then starts the second motor 10 via the control module, driving the gear 11 to rotate. The gear 11 meshes with the large gear ring, causing the rotating disk 9 to rotate on the mounting plate 8. This causes the clamping blocks 12 to move inward along the rotating disk 9, clamping and fixing the PE pipes. This allows for centered clamping of PE pipes of different sizes, facilitating welding. After fixing, the welding area of ​​the PE pipes is heated, and then the first motor 61 is started, driving the wire... Rotating rod 6 causes slider 7 to move under the action of the thread, bringing the sides of the PE pipe fittings that are close to each other into contact. After the weld joint of the PE pipe fittings cools down, hot melt welding can be performed. When welding PE bends at different angles, knob 13 can be held to rotate worm 4. Worm 4 and worm wheel 5 mesh with each other, driving the rotating frame 2 to rotate, causing slide rod 21 to slide along slide rail 3, driving the PE straight pipe clamped between clamping blocks 12 to rotate, so that the weld joint of the PE straight pipe is aligned with the weld joint of the PE bend. This allows for adjustment according to the angle of the PE bend, facilitating hot melt welding of PE bends at different angles, and making it flexible to use.

[0023] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
