However, in the actual welding process, the presence of welding slag, dust and other impurities on the workbench can cause defects in the welding position. Therefore, a device that can remove dust from the welding area during welding is needed. Utility Model Content

[0031] 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.

[0032] Please see Figure 1-9 This utility model provides a technical solution:

[0033] Example 1:

[0034] This high-pressure manifold welding device mainly consists of a base 1, a three-jaw chuck 2, a rotating platform 3, an adjustable support frame 4, a welding torch 5 and its auxiliary components, a reducer 6, a drive motor 7, a drive gear 8, a gear ring 9, a workpiece clamping assembly 10, a dust removal assembly 11, casters 12, and an intelligent controller. The workpiece clamping assembly 10 is driven by double telescopic cylinders 109, and the dust removal assembly 11 is adjustable, allowing the user to set the blade direction of the turbine 111 and select whether it is blowing or sucking dust. The drive motor 7 is connected to the intelligent controller, which allows for precise control of the drive motor 7.

[0035] The base 1, made of metal, serves as the supporting foundation for the entire device. Casters 12 with brakes are installed at the bottom of the base 1 to facilitate movement and positioning of the device. When the device needs to be moved, the brakes are released; once the designated position is reached, the brakes are engaged to secure it.

[0036] The three-jaw chuck 2 is securely fixed to the upper surface of the base 1 by bolts and other connecting parts. It is mainly used to fix high-pressure manifold connectors. Its three jaws can be simultaneously contracted or expanded manually or electrically to accommodate high-pressure manifold connectors of different pipe diameters.

[0037] The rotating platform 3 is rotatably mounted on the base 1 via bearings, enabling smooth circular motion. A reducer 6 and a drive motor 7 are mounted on the rotating platform 3. The output shaft of the drive motor 7 is connected to the input end of the reducer 6 via a coupling, transmitting power to the reducer 6. A drive gear 8 is fixed on the output shaft of the reducer 6, while a gear ring 9 is fixedly mounted on the base 1. The drive gear 8 and the gear ring 9 mesh with each other. The drive motor 7 is connected to an intelligent controller, which can precisely control parameters such as the speed and direction of the drive motor 7. This is a mature existing technology widely used in industrial automation control. When the drive motor 7 starts, the power is reduced by the reducer 6, driving the drive gear 8 to rotate. The drive gear 8 rolls on the gear ring 9, thus causing the rotating platform 3 to rotate around the base 1.

[0038] The adjustable support frame 4 is fixed on the rotating platform 3. It consists of multiple rods and joints, which are connected by bolts or movable pins, enabling telescopic and multi-angle adjustment. The welding torch 5 is installed at the end of the adjustable support frame 4. By adjusting the height and angle of the adjustable support frame 4, the welding torch 5 can be precisely positioned at the welding position of the high-pressure manifold.

[0039] The welding torch 5 is equipped with additional components such as a welding power source and a wire feeding mechanism. The welding power source provides a stable welding current and voltage to the welding torch 5 to ensure the stability of the welding process and the welding quality. The wire feeding mechanism accurately delivers the welding wire required for welding to the welding area, and its wire feeding speed can be adjusted according to the welding process requirements. These additional components are electrically and mechanically connected to the welding torch 5 and work together to complete the welding task.

[0040] The fixing plate 101 is fixed on the base 1, and the slide rod 102 is installed parallel to the fixing plate 101 to provide a sliding track for the slider 103.

[0041] Two sliders 103 are fitted onto the slide rod 102 and can slide freely along the slide rod 102. Each slider 103 corresponds to a telescopic cylinder 109, which is fixed on the fixed plate 101, and its movable end is fixedly connected to the corresponding slider 103.

[0042] A clamping block 104 is fixed on the slider 103 for clamping the weldment. In this embodiment, the clamping of the high-pressure manifold fitting is achieved by simultaneously controlling the extension and retraction of the two telescopic cylinders 109.

[0043] The dust removal assembly 11 includes a turbine 111 and a protective housing 112. The turbine 111 is fixed on the shaft of the drive motor 7 and located at the end away from the reducer 6. When the drive motor 7 is running, it drives the turbine 111 to rotate synchronously. Users can change the installation direction of the turbine 111 according to actual needs to set the working mode of the turbine 111. A protective housing 112 is installed on one side of the drive motor 7, which encloses the turbine 111. The protective housing 112 is provided with an air outlet pipe 113 and several through holes 114 for air intake.

[0044] A dust removal nozzle 115 is fixedly installed on the adjustable support frame 4. The dust removal nozzle 115 is connected to the air outlet pipe 113 through a pipe. When the turbine 111 is set to different directions, if it is in the dust suction mode, the turbine 111 rotates to generate suction and draws air in through the through hole 114 of the protective shell 112; if it is in the dust blowing mode, the turbine 111 pushes air from the air outlet pipe 113 through the pipe and sprays it out onto the dust removal nozzle 115.

[0045] When starting the welding work, first move the device to a suitable position and fix it, and use the three-jaw chuck 2 to initially fix the connector of the high-pressure manifold. At the same time, activate the two telescopic cylinders 109. The moving ends of the two telescopic cylinders 109 respectively drive the corresponding sliders 103 to slide on the slide rod 102, so that the two clamping blocks 104 are relatively close to each other, thereby clamping the pipe of the high-pressure manifold.

[0046] The operator sets the parameters of the drive motor 7 via the intelligent controller. After the intelligent controller is activated, the drive motor 7 operates according to the set parameters. The adjustable support frame 4 is adjusted according to welding requirements to position the welding torch 5 in the welding position. The welding power supply and wire feeding mechanism are turned on to begin the welding operation. The drive motor 7 drives the rotating platform 3 to rotate, causing the welding torch 5 to perform circumferential welding around the high-pressure manifold.

[0047] During the welding process, the user determines the working mode of the dust removal component 11 based on the actual site conditions. If it is necessary to collect smoke and dust, the turbine 111 is set to the suction mode, and the drive motor 7 drives the turbine 111 to rotate, generating suction to suck in the smoke and dust; if it is necessary to blow away the smoke and dust, it is set to the blowing mode, and air is sprayed out from the dust removal nozzle 115 to blow away the smoke and dust.

[0048] Example 2:

[0049] The high-pressure manifold welding device in this embodiment also includes a base 1, a three-jaw chuck 2, a rotating platform 3, an adjustable support frame 4, a welding torch 5 and its auxiliary components, a reducer 6, a drive motor 7, a drive gear 8, a gear ring 9, a workpiece clamping assembly 10, a dust removal assembly 11, casters 12, and an intelligent controller. Unlike Embodiment 1, the workpiece clamping assembly 10 uses a telescopic cylinder 109 to drive a slider 103 to clamp the workpiece.

[0050] Two sliders 103 are fitted onto a slide rod 102 and can slide freely along the slide rod 102. Each slider 103 is rotatably connected to a crank 105 via a pin. A connecting rod 106 is rotatably mounted on a fixed plate 101. The rotation center of the connecting rod 106 is located at its midpoint. The two ends of the connecting rod 106 are rotatably connected to the cranks 105 on the two sliders 103 via pins.

[0051] A telescopic cylinder 109 is fixedly installed on the fixed plate 101, and the movable end of the telescopic cylinder 109 is fixedly connected to one of the sliders 103. A clamping block 104 is fixed on the slider 103 for directly clamping the welded parts of the high-pressure manifold.

[0052] In addition, in this embodiment, a number of clamping pieces 107 with V-grooves are fixed on the slider 103. The clamping pieces 107 on the two sliders 103 are staggered, and an elastic layer 108, such as a rubber layer, is fixed at the V-groove position to increase friction and protect the surface of the weldment.

[0053] During the welding operation, the telescopic cylinder 109 is first activated. The movable end of the telescopic cylinder 109 drives the connected slider 103 to slide on the slide rod 102. Through the transmission action of the crank 105 and the connecting rod 106, the other slider 103 slides synchronously in the opposite direction, thereby realizing that the two clamping blocks 104 move closer or further apart, completing the clamping or releasing action of the weldment.

[0054] Working principle:

[0055] The device first moves to the welding station via the braked casters 12 at the bottom of the base 1, then brakes the base 1 to ensure stability. The operator uses a three-jaw chuck 2 to clamp the connector of the high-pressure manifold, adjusting the jaws manually or electrically to accommodate connectors of different diameters, thus achieving axial positioning of the weldment. Subsequently, the weldment clamping assembly 10 is activated, selecting a clamping method based on different embodiments—in the double telescopic cylinder 109 scheme, two symmetrical telescopic cylinders 109 synchronously push the slider 103 to slide towards each other along the slide rod 102, causing the clamping block 104 to clamp the pipe body from both sides; in the single telescopic cylinder 109 scheme, a single telescopic cylinder 109 drives one side of the slider 103, using a crank 105 and connecting rod 106 mechanism to force the other side of the slider 103 to slide in the opposite direction, causing the clamping block 104 to synchronously clamp the pipe body. The V-groove and elastic layer 108 design of the clamping block 104 can adapt to different pipe diameters and protect the weldment surface.

[0056] After the workpiece is fixed, the operator adjusts the telescopic joint of the adjustable support frame 4 to adjust the height, angle, and horizontal position of the welding torch 5, ensuring it is precisely aligned with the weld joint. The welding power supply and wire feeding mechanism are then activated, and the welding current, voltage, and wire feeding speed are set to ensure process parameters are matched. The intelligent controller synchronously sets the speed and direction of the drive motor 7. The drive motor 7 reduces its output speed and increases its torque through the reducer 6, causing the drive gear 8 to mesh with the fixed gear ring 9 on the base 1, driving the rotating platform 3 to rotate uniformly around the base 1. Driven by the rotating platform 3, the welding torch 5 continuously welds along the circumferential weld seam of the high-pressure manifold, achieving fully automated operation.

[0057] During welding, the dust removal component 11 dynamically switches the direction of the turbine 111 according to on-site needs: if it is necessary to collect fumes, the turbine 111 blades are adjusted to suction mode, and the turbine 111 rotates in reverse to generate negative pressure, which draws in fumes through the through-hole 114 of the protective shell 112 and discharges them through the pipeline; if it is necessary to disperse fumes, it switches to blowing mode, and the turbine 111 rotates in the forward direction to force air into the pipeline, which is then sprayed out by the dust removal nozzle 115 to remove fumes from the welding area. The dust removal nozzle 115 moves synchronously with the welding torch 5 to ensure a clean welding environment.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
