Technical Field
[0001] This utility model relates to a welding device, and more particularly to a gate welding device. Background Technology
[0002] In existing technologies, gate welding equipment is widely used in industrial manufacturing, particularly in pipeline engineering, water conservancy projects, and the oil and gas industry. This equipment is primarily used to securely connect metal gates to pipelines or other structural components. During operation, operators typically need to fix the workpiece to be welded onto a specific fixture, and then perform the welding operation on the circumference of the metal component using electric welding equipment. The welding process requires precise control of current, voltage, and welding time to ensure that the weld quality meets the requirements for strength and sealing. However, due to the complex and variable nature of actual production environments, manual operation remains the primary method.
[0003] Currently, welders face numerous challenges when welding gate panels, particularly the harsh working environment, which significantly impacts their health. The intense heat generated during welding leaves workers in a state of prolonged discomfort, while the release of harmful gases and fumes can easily lead to respiratory illnesses and skin burns. Furthermore, manual welding is inefficient and inconsistent, potentially resulting in varying product quality and further increasing the costs of subsequent inspection and rework. These issues urgently need to be addressed. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a gate welding device that replaces manual circumferential welding of gates.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a gate welding device, comprising welding equipment for welding gates, and a welding table for driving the welding equipment to weld around the gate. The welding table includes a fixing plate for forming a fixed position with the gate. A housing is rotatably mounted on the fixing plate. An alignment member is provided at the center of the housing, extending from the center of the fixing plate. The alignment member is used to locate the center of the gate. An adjusting arm is fixedly mounted on the other side of the housing relative to the fixing plate. The welding equipment is detachably connected to the adjusting arm. The adjusting arm can adjust the distance between the welding equipment mounted thereon and the axis of the alignment member.
[0006] The beneficial effects of this invention are as follows: By setting up a welding table and a fixing plate, a stable relative positional relationship can be formed between the welding equipment and the gate, ensuring accuracy during the welding process. The alignment component inside the chassis can quickly determine the center position of the gate, thereby improving welding efficiency and accuracy. The design of the adjusting arm allows the welding equipment to adjust its distance from the axis of the alignment component as needed, adapting to the welding requirements of gates of different sizes and shapes. This modular design also facilitates equipment maintenance and replacement, improving the overall flexibility and practicality of the equipment. As a preferred method, the alignment component uses a laser point positioning device, which aligns a laser beam with the center mark on the surface of the gate, and the alignment status is confirmed by visual inspection or an automated detection system, further improving positioning accuracy and operational convenience.
[0007] Furthermore, a stabilizing component is also provided inside the chassis. The alignment member is located at the center of the stabilizing component, and the stabilizing component is used to prevent the alignment member from deviating from the center of the fixed plate. The alignment member is aligned with the center of the gate plate by laser.
[0008] By incorporating stabilizing components, misalignment between the mounting plate and the chassis center position due to vibration or external interference during chassis operation can be effectively prevented, ensuring the stability of the welding process. The stabilizing component design also reduces equipment wear and extends its service life during long-term operation. Simultaneously, laser alignment offers high precision, significantly improving the efficiency and welding quality of the welding equipment. As a preferred approach, the stabilizing component can include a multi-layered vibration-damping structure, such as a combination of elastic washers and rigid support frames, to further enhance its vibration resistance, thereby maintaining good stability even under complex operating conditions.
[0009] Furthermore, the stabilizing component includes a fixing cylinder extending from the center of the fixing plate toward the inside of the chassis, a first bearing and a second bearing sleeved on the fixing cylinder and respectively disposed on the inner and outer sides of the chassis, and a fastening groove is formed between the first bearing and the second bearing for the chassis bottom plate to be inserted and fixed therebetween, the width of the fastening groove being adjustable.
[0010] The design, featuring a fixed cylinder and dual bearings, creates a stable support structure on both the inner and outer sides of the chassis, ensuring that the alignment components are always centered on both the fixed plate and the chassis. The adjustable groove width provides greater flexibility, allowing adjustment of the tightness between the chassis base plate and the bearings as needed, thereby optimizing assembly accuracy and operational stability. Furthermore, this structure is simple and easy to manufacture and maintain. As a preferred method, the groove width can be adjusted via a threaded adjustment mechanism; operators simply rotate the adjusting nut to change the groove width, making it both convenient and efficient.
[0011] Furthermore, it also includes a rotating assembly for driving the chassis to rotate. The rotating assembly includes a fixed tooth located between the fixed plate and the second bearing, a rotating tooth meshing around the fixed tooth, and a drive motor provided with driving force for the rotating tooth and located inside the chassis. The fixed plate is provided with a plurality of slot width adjustment holes. Each slot width adjustment hole is provided with an adjustment bolt whose one end abuts against the surface of the fixed tooth. The adjustment bolt moves within the slot width adjustment hole to adjust the slot width of the fastening slot.
[0012] The rotating assembly design enables precise rotation control of the chassis, thus meeting the requirements for circumferential welding around the gate. The meshing transmission method of the fixed and rotating teeth not only boasts high transmission efficiency but also features a compact structure and small footprint. The combination of the slot width adjustment hole and the adjusting bolt allows users to fine-tune the width of the fastening slot according to actual conditions, further enhancing the adaptability and stability of the equipment. As a preferred option, the adjusting bolt can be equipped with a spring preload device to automatically compensate for gaps during adjustment, preventing loosening issues caused by long-term use.
[0013] Furthermore, the fixed cylinder is fitted with at least two clamping blocks on the second bearing, and a sensing plate is clamped between the two clamping blocks. A sensor is correspondingly installed inside the chassis. When the sensor senses the sensing plate again after rotating one revolution, it transmits a signal to the control system to stop the rotation of the chassis.
[0014] By combining the clamping block and the sensing element, the rotation status of the chassis can be monitored in real time, and the machine can automatically stop after completing one revolution of welding, avoiding over-welding or incomplete welding. The linkage mechanism between the sensor and the sensing element features fast response speed and high reliability, significantly improving the automation level of the welding process. Furthermore, this design reduces the need for manual intervention and minimizes the possibility of operational errors. As a preferred approach, the sensing element can be made of magnetic material to be used in conjunction with a Hall effect sensor, thereby achieving non-contact detection and further enhancing the system's durability and sensitivity.
[0015] Furthermore, a positioning groove is provided at the center of the side of the adjusting arm facing away from the chassis, and at least three guide seats are provided on the adjusting arm to guide the adjusting arm to move within them. At least one guide seat is provided with a positioning hole for the positioning bolt to pass through. The positioning bolt is pressed against the bottom of the positioning groove to prevent the adjusting arm from moving. A handle is fixedly provided on the two adjacent guide seats without positioning holes.
[0016] The combined design of the positioning groove and guide seat provides precise guidance for the adjusting arm, ensuring it maintains a linear trajectory throughout the adjustment process, thereby improving the positional accuracy of the welding equipment. The positioning bolt design effectively locks the adjusting arm in place, preventing accidental displacement during welding. The handle allows operators to manually adjust the position of the adjusting arm, enhancing the ease of operation. As a preferred option, the guide seat can incorporate a ball bearing track structure to reduce friction and improve the smoothness of the adjusting arm's sliding motion, further enhancing the overall performance of the equipment.
[0017] Furthermore, a rotating motor is fixedly installed on the adjusting arm, one end of the rotating motor is connected to a rotating plate, an eccentric frame is hinged to the eccentric position of the rotating plate, and a placement frame for placing welding equipment is hinged to the other end of the eccentric frame. When the rotating motor drives the eccentric frame to move eccentrically in a circular motion, the placement frame is driven to move linearly through the eccentric frame.
[0018] By linking the rotating motor, rotating plate, and eccentric frame, rotational motion can be converted into linear motion, thereby achieving precise radial adjustment of the welding equipment. This design is not only compact but also highly efficient in transmission, meeting the needs of different welding ranges. Furthermore, the eccentric frame's movement offers a wide range of stroke adjustment, further enhancing the equipment's adaptability. As a preferred approach, the hinge point of the eccentric frame can be designed as an adjustable structure, for example, through a threaded connection to achieve fine-tuning of the angle, to meet the requirements of special welding tasks.
[0019] Furthermore, the placement frame includes a Y-shaped guide rod and a guide block for inserting the Y-shaped guide rod to form a guide for the Y-shaped guide rod to move. One end of the Y-shaped guide rod is hinged to the eccentric frame, and the other end is provided with a placement hole for welding equipment to be fitted into it.
[0020] The combined design of the Y-shaped guide rod and guide block provides a stable guiding path for the welding equipment, ensuring that it does not deviate or wobble during linear movement, thereby improving welding quality. The placement hole design facilitates the installation and disassembly of the welding equipment, enhancing its versatility and maintenance convenience. Furthermore, this modular design allows for the replacement of different sized placement racks according to varying welding needs, further expanding the equipment's application range. As a preferred option, the guide block can have a built-in lubrication channel to reduce frictional resistance during the sliding process of the Y-shaped guide rod, thus extending the equipment's service life.
[0021] Furthermore, a stroke adjustment plate is slidably disposed at the center of the rotating plate, the eccentric frame is hinged to the stroke adjustment plate, and the circumference of the rotating plate is provided with fixing holes for fixing bolts to be inserted. The fixing bolts are pressed against the surface forming the adjustment plate through the fixing holes to form the positioning of the stroke adjustment plate.
[0022] The design of the stroke adjustment plate allows for flexible adjustment of the initial position of the eccentric frame according to actual needs, thereby changing the range of motion of the welding equipment. The locking function of the fixing bolts ensures that the stroke adjustment plate is firmly fixed after adjustment, preventing displacement during welding. This design not only improves the adaptability of the equipment but also simplifies the operation process and reduces the difficulty of use. As a preferred option, the stroke adjustment plate can be equipped with a scale so that operators can intuitively read the adjustment amount, thereby improving the accuracy and efficiency of adjustment.
[0023] Furthermore, the fixing plate is provided with fixing posts on all four sides facing the gate plate, and the fixing plate is provided with a control switch for controlling the four fixing posts. When the control switch is turned on or off, it will generate or deactivate magnetic force at the four fixing posts.
[0024] The fixed column design achieves rapid fixation to the gate through electromagnetic adsorption, which is not only simple to operate but also provides reliable fixation. The centralized control method of the control switch greatly simplifies the operation steps and improves work efficiency. Furthermore, this design can adapt to gates of different materials and shapes, exhibiting strong versatility. As a preferred option, the electromagnet core of the fixed column can be made of a high-permeability material and coated with a wear-resistant coating to improve adsorption force and extend service life, thereby better meeting the needs of industrial production.

[0033] This utility model embodiment provides a gate welding device, such as... Figure 1-8 The diagram shows a welding table 1, welding equipment (not shown), and an adjusting arm 7 for adjusting the welding range and position. The welding table 1 includes a fixed plate 11, on which a rotatable housing 12 is mounted. Inside the housing 12 is an alignment member 2 for locating the center point of the gate, which protrudes through a through hole 113 on the fixed plate 11 to communicate with the outside. To ensure that the alignment member 2 does not deviate from the center position of the overlapping fixed plate 11 and housing 12, a stabilizing component 3 is designed inside the housing 12. The stabilizing component 3 includes a fixed cylinder 31 extending from the center of the fixed plate 11 into the housing 12. A first bearing 32 and a second bearing 33 are fitted onto the fixed cylinder 31, forming a fastening groove 34 between the two bearings. The base plate 121 of the housing 12 is inserted into and fixed in the fastening groove 34, and the width of the fastening groove 34 can be adjusted by adjusting bolts 112. To achieve the rotation of the chassis 12, a rotating assembly 4 is also provided, which consists of a fixed gear 41, a rotating gear 42, and a drive motor 43. The fixed gear 41 is located between the fixed plate 11 and the second bearing 33, and the fixed gear 41 meshes with the rotating gear 42. The drive motor 43 is fixed on the chassis 2 and provides power to the rotating gear 42. The chassis 12's base plate 121 is clamped by the first bearing 32 and the second bearing 33 so that the chassis 12 can rotate about the axis of the first bearing 32 and the second bearing 33 when the rotating gear 42 rotates around the fixed gear 41. The fixed plate 11 is also provided with multiple slot width adjustment holes 111, and each slot width adjustment hole 111 is equipped with an adjustment bolt 112. By moving the adjustment bolt 112 in the slot width adjustment hole 111, the width of the fastening slot 34 is changed, thereby further stabilizing the rotation of the chassis 12.
[0034] In addition, the fixed cylinder 31 is fitted with two clamping blocks 35 outside the second bearing 33. A sensing plate 36 is clamped between the clamping blocks 35. A sensor 123 is installed inside the chassis 12 at the position corresponding to the sensing plate 36. When the sensor 123 rotates one revolution and senses the sensing plate 36 again, it will transmit a signal to the control system (not output in the figure) to stop the chassis 12 from rotating.
[0035] An adjusting arm 5 is installed on the other side of the chassis 12, i.e., the top plate 122. Welding equipment (not shown in the figure) is detachably connected to the adjusting arm 5. A positioning groove 51 is provided on the side of the adjusting arm 5 facing away from the chassis 12. The adjusting arm 5 also has multiple guide seats 52, at least one of which has a positioning hole 53. A positioning bolt 54 passes through the positioning hole 53 and abuts against the bottom of the positioning groove 51 to prevent the adjusting arm 5 from moving freely. Handles 55 are installed on the two adjacent guide seats 52 without positioning holes 53 to facilitate the operator's adjustment of the position of the adjusting arm 5. A rotary motor 56 is also fixed to the adjusting arm 5. One end of the rotary motor 56 is connected to a rotating plate 57. An eccentric frame 58 is hinged to the eccentric position of the rotating plate 57, and the other end of the eccentric frame 58 is hinged to a placement frame 59 for placing the welding equipment (not shown in the figure). When the rotating motor 56 drives the eccentric frame 58 to perform eccentric circular motion, the placement frame 59 moves linearly accordingly, thereby adjusting the distance between the welding equipment (not shown in the figure) and the axis of the alignment piece 2.
[0036] The placement frame 59 includes a Y-shaped guide rod 591 and a guide block 592. One end of the Y-shaped guide rod 591 is hinged to the eccentric frame 58, and the other end passes through the guide block 592 and has a placement hole 593 on its end face for connecting welding equipment (not shown in the figure). A stroke adjustment plate 573 is slidably disposed at the center of the rotating plate 57. The eccentric frame 58 is hinged to the stroke adjustment plate 573. Fixing holes 571 are provided on the periphery of the rotating plate 57. Fixing bolts 572 are pressed against the surface of the stroke adjustment plate 573 through the fixing holes 571 to fix the position of the stroke adjustment plate 573.
[0037] Four fixing posts 114 are provided on the four sides of the fixing plate 11 facing the gate. A control switch 115 is also installed on the fixing plate 11. When the control switch 115 is turned on or off, it will generate or deactivate the magnetic force at the four fixing posts 114, thereby firmly adsorbing the fixing plate 11 onto the gate.
[0038] The usage process of this embodiment is as follows: First, locate the center point of the gate plate. Align the laser point of the fixing plate 11 with the center point of the fixing piece 2. This position is the welding center point. Then, press the control switch 115 to generate magnetic force and fix the fixing post 114 (electromagnet) to the gate plate. Next, adjust the position of the adjusting arm 5 and the stroke adjusting plate 573 to determine the welding range and welding width. Finally, start the equipment to weld around the gate plate. When the equipment reaches the one-circle position, the sensor 123 senses the signal transmitted by the sensing plate 36 to the control system (not output in the figure) and automatically stops the machine. It should be noted that how the control switch 115 controls the fixing post 114 (which is an electromagnet) to generate or demagnetize is existing technology and will not be elaborated further.
[0039] As a preferred embodiment, the chassis 12 is also provided with a control panel 124, the alignment member 2 is connected to the control panel 124 and provides a reminder on the control panel 124 when the center of the gate is not aligned.
[0040] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
