Description

Technical Field

[0001] This utility model belongs to the technical field of welding auxiliary equipment, specifically relating to an auxiliary welding device for an argon arc welding machine. Background Technology

[0002] Welding auxiliary equipment primarily focuses on fixing, positioning, and rotating workpieces during the welding process to ensure welding accuracy, improve efficiency, and reduce manual intervention. It is widely used in machinery manufacturing, automotive, aerospace, and other fields, with argon arc welding (argon arc welding) being particularly favored due to its high weld quality and applicability to non-ferrous metals. However, this field faces numerous challenges, such as poor workpiece alignment, weld deformation, and complex operation, all of which directly impact weld quality and production efficiency.

[0003] In existing technologies, the design of automatic TIG welding machine fixtures often focuses on basic clamping functions, neglecting multi-functional integration and automated coordination. For example, taking the patent document "An Automatic TIG Welding Machine Fixture" with publication number CN 221087570 U as an example, this patent discloses a fixture including a base plate and a support platform, which achieves workpiece fixation through a clamping structure and a control structure. Although this patent simplifies the clamping operation with double-ended studs and sliding plates, its drawback is that the entire fixture is located above the worktable, requiring multi-directional adjustments in the up, down, left, and right directions to clamp the workpiece. This results in numerous operation steps and long adjustment times, increasing the labor intensity of operators and reducing work efficiency. Especially when welding shaft-type and groove-type workpieces, this patent lacks precise positioning and rotation functions, which can easily cause workpiece eccentricity or uneven welding, failing to meet the requirements of high-precision welding.

[0019] The following are specific implementation cases and appendices. Figures 1-5 The present invention will be further described below, but it is not limited to these embodiments. The present invention provides a technical solution: an auxiliary welding device for an argon arc welding machine, comprising: a welding protection platform 1, and further comprising: a concave fixing component, the concave fixing component being fixedly disposed on the upper wall of the welding protection platform 1; a rotation power component, the rotation power component being disposed on the lower wall of the welding protection platform 1, and the rotation power component and the concave fixing component being connected by a toothed belt; a shaft clamping component, the shaft clamping component being disposed on the upper wall of the welding protection platform 1; a shaft fixing component, the shaft fixing component being disposed on the upper wall of the welding protection platform 1; three shaft positioning components, two shaft positioning components being disposed on the upper wall of the welding protection platform 1 respectively, and the other shaft positioning component being disposed at the front end of the shaft clamping component; an insulating stabilizing frame being provided on the lower wall of the welding protection platform 1; a high-temperature resistant coating being provided on the upper wall of the welding protection platform 1; and four adjusting feet being provided on the lower wall of the insulating stabilizing frame.

[0020] As a preferred embodiment, the concave fixing assembly further includes: a concave fixing shaft 2, which is mounted on the upper wall of the welding protection platform 1 via two support plates; a concave slot 3, which is fixedly mounted on the inner end of the concave fixing shaft 2; and a driven gear 4, which is fixedly mounted on the other end of the concave fixing shaft 2.

[0021] As a preferred embodiment, the rotational power assembly further includes: a rotational power motor 5, which is fixedly mounted on the lower wall of the welding protection platform 1; and a drive gear 6, which is fixedly mounted on the drive end of the rotational power motor 5, and the drive gear 6 and the driven gear 4 are connected by a toothed belt.

[0022] As a preferred embodiment, the shaft clamping assembly further includes: a shaft clamping column 7, which is fixedly installed on the upper wall of the welding protection platform 1; a shaft clamping crossbeam 8, which is movably mounted on the upper end of the shaft clamping column 7 via a hinge; and a shaft clamping hydraulic actuator 9, which is mounted on the rear wall of the welding protection platform 1 via a rotating seat, and the drive end of the shaft clamping hydraulic actuator 9 is mounted on the rear end of the shaft clamping crossbeam 8 via a hinge.

[0023] As a preferred embodiment, the shaft fixing assembly further includes: a shaft fixing cylinder 10, which is fixedly mounted on the upper wall of the welding protection platform 1 by two support plates; and a shaft fixing rotating disk 11, which is fixedly mounted on the drive end of the shaft fixing cylinder 10, and the surface of the shaft fixing rotating disk 11 is provided with an anti-slip coating.

[0024] As a preferred embodiment, the three axis positioning components further include: an axis positioning seat 12, which is fixedly mounted on the upper wall of the welding protection platform 1; and two axis positioning rollers 13, which are movably mounted inside the axis positioning seat 12 via an axis.

[0025] When using this device, the operator first places the welding protection platform 1 in the designated position using the insulated stabilizer. The four adjustable feet allow the insulated stabilizer to keep the welding protection platform 1 level. Simultaneously, the operator connects an external AC power supply to the device to provide power to the electrical equipment, and connects a matching controller to provide control and operating logic for the equipment. The operator also connects an external hydraulic source to the shaft clamping hydraulic unit 9 to provide power, and an external air source to the shaft fixing cylinder 10 to provide power. It should be noted that the rotation power motor 5 is an electrically controllable brake motor.

[0026] Working principle: When using this device, the operator directly clamps the grooved welding material into the concave groove 3 and places the shaft welding material on the shaft positioning rollers 13 of the two sets of shaft positioning seats 12 on the welding protection platform 1. Then, the shaft fixing cylinder 10 drives the shaft fixing rotating disk 11 to move towards the shaft welding material until the shaft fixing rotating disk 11 adheres the shaft welding material to the outer wall of the grooved welding material. At this time, the drive end of the shaft clamping hydraulic device 9 extends, and the shaft clamping crossbeam 8 rotates around the top of the shaft clamping column 7 as the axis until the shaft welding material is between the shaft positioning rollers 13 of the three sets of shaft positioning seats 12.

[0027] Then, the operator uses an argon arc welding device to perform an electric weld on the gap between the shaft weld and the groove weld, fixing them in place. Next, the power motor 5 is turned, driving the drive gear 6, which in turn drives the driven gear 4 via a toothed belt. This, in turn, causes the concave fixed shaft 2 to rotate, thus rotating the concave slot 3. Because the shaft weld and the groove weld are welded together, they are driven by the concave slot 3, rotating synchronously. The operator then uses the argon arc welding device to perform a complete weld between the shaft weld and the groove weld, thus achieving precise positioning between them.

[0028] Example: The auxiliary welding device for an argon arc welding machine mainly includes a welding protection platform 1, a concave fixing assembly, a rotation power assembly, a shaft clamping assembly, a shaft fixing assembly, and three shaft positioning assemblies. The welding protection platform 1 serves as the basic support structure, with an insulating stabilizing frame on its lower wall. The lower wall of the insulating stabilizing frame has four adjusting feet for leveling the platform. The upper wall of the welding protection platform 1 is coated with a high-temperature resistant coating to withstand the high temperatures during welding. The concave fixing assembly fixes the grooved weld material via a concave fixing shaft 2 and a concave slot 3. The rotation power assembly drives the concave fixing shaft 2 to rotate via a rotation power motor 5 and a drive gear 6. The shaft clamping assembly clamps the shaft weld material via a shaft clamping column 7, a shaft clamping beam 8, and a shaft clamping hydraulic device 9. The shaft fixing assembly assists in fixing the shaft weld material via a shaft fixing cylinder 10 and a shaft fixing rotating disk 11. Three shaft positioning assemblies are respectively installed on the upper wall of the welding protection platform 1 and the front end of the shaft clamping assembly. Each shaft positioning assembly includes a shaft positioning seat 12 and two shaft positioning rollers 13, which are used to support and guide the shaft welding material.

[0029] The welding protection platform 1 is constructed from high-strength steel plate to ensure stability and durability. The platform surface is coated with a 0.5mm thick high-temperature resistant ceramic coating, capable of withstanding temperatures up to 1000°C. The insulating stabilizer is made of insulating material and is bolted to the lower wall of the welding protection platform 1. Adjustable feet are located at each of the four corners of the insulating stabilizer; these are threaded adjustable feet, allowing workers to adjust the platform's level using a wrench. During installation, workers first place the welding protection platform 1 on a flat surface, adjust the feet to ensure the platform is level, and then verify this using a level. All component mounting holes on the platform are pre-drilled, with the hole diameter customized according to the component dimensions.

[0030] The concave fixing assembly includes a concave fixing shaft 2, a concave slot 3, and a driven gear 4. The concave fixing shaft 2 is a steel shaft, mounted on the upper wall of the welding protection platform 1 via two support plates. The support plates are made of Q235 steel and are bolted to the platform. The concave slot 3 is installed at one end of the concave fixing shaft 2. The concave slot 3 is a groove structure made of wear-resistant steel, with an adjustable groove width to accommodate different diameters of grooved welding material. The concave slot 3 is connected to the concave fixing shaft 2 via a keyway and secured with set screws. The driven gear 4 is fixed to the other end of the concave fixing shaft 2. During installation, the worker first tightens the bolts on the support plates, then installs the concave fixing shaft 2, ensuring that the concave fixing shaft 2 can rotate freely within the bearing housing of the support plates. The concave slot 3 must be aligned with the shaft center during installation.

[0031] The rotational power assembly includes a rotational power motor 5 and a drive gear 6. The rotational power motor 5 is a three-phase asynchronous brake motor, fixed to the lower wall of the welding protection platform 1 via a motor mount. The motor mount is welded from angle steel and connected to the platform with bolts. The drive gear 6 is mounted on the motor drive end and is connected to the driven gear 4 via a toothed belt. The toothed belt is a synchronous belt, model HTD5M-20, and its length is calculated based on the gear center distance. During installation, the worker first fixes the motor mount, then installs the rotational power motor 5 and the drive gear 6, adjusting the belt tension using a tensioning pulley to ensure the belt does not slip.

[0032] The shaft clamping assembly includes a shaft clamping column 7, a shaft clamping beam 8, and a shaft clamping hydraulic actuator 9. The shaft clamping column 7 is a square steel tube, fixed to the upper wall of the welding protection platform 1 by foundation bolts. The shaft clamping beam 8 is an I-beam, connected to the top of the shaft clamping column 7 by a heavy-duty rotary hinge, allowing the beam to rotate in the vertical plane. The shaft clamping hydraulic actuator 9 is a double-acting hydraulic cylinder, mounted on the rear wall of the welding protection platform 1 via a rotating seat. The drive end of the hydraulic actuator is connected to the rear end of the shaft clamping beam 8 via a ball joint.

[0033] The shaft fixing assembly includes a shaft fixing cylinder 10 and a shaft fixing rotating disk 11. The shaft fixing cylinder 10 is a double-acting cylinder, fixed to the upper wall of the welding protection platform 1 by two support plates. The support plates are made of steel plates and fixed with bolts. The shaft fixing rotating disk 11 is mounted on the cylinder drive end. The rotating disk has a disc structure with a surface coated with an anti-slip rubber coating, and a friction coefficient greater than 0.8. During installation, the worker aligns the cylinder with the support plates and tightens it with bolts. The pneumatic pipeline uses nylon tubing and connects to an external air source.

[0034] Three shaft positioning assemblies are respectively installed on the upper wall of the welding protection platform 1 and at the front end of the shaft clamping assembly. Each shaft positioning assembly includes a shaft positioning seat 12 and two shaft positioning rollers 13. The shaft positioning seat 12 is a cast iron base and is fixed to the platform with anchor bolts. The shaft positioning rollers 13 are mounted on the shaft by bearings and secured with retaining rings. The roller spacing is adjustable to accommodate different shaft weld diameters. During installation, the worker first positions the seat and then installs the rollers, ensuring that the rollers rotate freely. The three assemblies are arranged in a triangle to stably support the shaft weld.

[0035] The workflow is divided into initialization, solder placement, clamping, welding, and completion stages. The worker first initializes the equipment by adjusting the support legs to level the welding protection platform 1, using a level to verify this. Then, external resources are connected: AC power is connected to the control cabinet via a cable; the hydraulic power source is connected to the shaft clamping hydraulic unit 9 via a hose; and the air source is connected to the shaft fixing cylinder 10 via a pipeline. The controller is a Siemens S7-1200 PLC, installed inside the control cabinet, and equipped with digital input / output modules.

[0036] The operator inserts the grooved solder into the concave slot 3, ensuring the solder adheres to the slot opening. Then, the shaft solder is placed on the shaft positioning rollers 13 of the two sets of shaft positioning seats 12 on the welding protection platform 1. The shaft solder is supported by the rollers and can roll slightly. Pressing the start button via the controller interface activates the shaft fixing cylinder 10. The cylinder drives the shaft fixing rotating disk 11 to move towards the shaft solder until the rotating disk adheres to the outer wall of the shaft solder, pressing the shaft solder against the grooved solder. A pressure sensor monitors the contact force, setting a threshold of 100N to ensure a firm fit.

[0037] Next, the controller activates the shaft clamping hydraulic actuator 9. The drive end of the hydraulic actuator extends, pushing the shaft clamping beam 8 to rotate downwards around the top of the shaft clamping column 7. The front end of the shaft clamping beam 8 presses against the shaft welding material, fixing it between the three sets of shaft positioning rollers 13. The hydraulic pressure is fed back by the pressure sensor, and the controller adjusts the relief valve to maintain stable pressure.

[0038] After fixation, the operator uses an argon arc welding device to perform a spot weld on the gap between the shaft weld and the groove weld to achieve initial fixation. Then, the controller starts the rotation motor 5, which drives the drive gear 6 to rotate, which in turn drives the driven gear 4 and the concave fixed shaft 2 to rotate via a toothed belt. The concave groove 3 drives the weld assembly to rotate slowly, which is adjustable. The operator performs continuous welding, with the welding torch operated by a robotic arm or manually, to ensure a uniform weld. After welding is completed, the controller stops the motor and releases the clamping and fixing devices, allowing the operator to remove the welded part.

[0039] The electrical control system is the core of the entire device, ensuring that all components work in coordination. The system includes a power supply module, a control module, an execution module, and a sensor module.

[0040] Power module: An external three-phase AC power supply is connected to the control cabinet and distributed via the main circuit breaker.

[0041] Control module: The PLC acts as the main controller, with input signals from buttons, limit switches, and sensors; the output signals control contactors, relays, and solenoid valves.

[0042] Operating Logic: After the system is powered on, the PLC executes the initialization program to detect the position of each component. For example, it checks whether the shaft clamping beam 8 is in the initial position via limit switches. The operator sets parameters such as welding speed and pressure values ​​through the HMI. Start-up Sequence: When the "Start" button is pressed, the PLC first outputs a signal to energize the solenoid valve of the shaft fixing cylinder 10, causing the cylinder to extend. After the cylinder reaches its position, the limit switch signal triggers the shaft clamping hydraulic actuator 9 to operate. The solenoid valve of the hydraulic actuator is controlled by the PLC, and the proportional valve adjusts the flow rate to achieve smooth movement. During welding, the PLC sends pulse signals to control the frequency converter of the rotating power motor 5 to adjust the speed. The motor is a brake motor; when stopping, the PLC sends a brake signal to ensure immediate cessation.

[0043] Control Logic: Sequential control logic is employed, with each step awaiting the completion signal of the previous step. For example, during the welding stage, the PLC monitors the current from the welding machine via a current sensor to ensure welding quality. If the sensor detects an anomaly, the PLC triggers an alarm and stops the equipment. Safety logic includes an emergency stop button and a light curtain; pressing the emergency stop button cuts off all power.

[0044] Execution module: The rotation power motor 5 is controlled by a frequency converter to achieve soft start and speed regulation. The shaft clamping hydraulic device 9 and the shaft fixing cylinder 10 are controlled by solenoid valves, which are two-position five-way valves driven by the PLC output point.

[0045] Sensor module: Includes a pressure sensor to monitor hydraulic and pneumatic pressure; an encoder to monitor motor speed; and a temperature sensor to monitor the temperature of the welding area. Sensor signals are connected to the PLC analog input module for real-time processing.
