Description

Technical Field

[0001] This invention relates to the field of welding machine technology, and in particular to a welding machine for producing outdoor tent frames. Background Technology

[0002] Outdoor tent frames are core components that ensure the overall shape and stability of the tent. They play a crucial role in overall support and pressure resistance, directly affecting the tent's sturdiness and wind resistance during outdoor use. In the industrial production process of tent frames, welding is an essential and critical step. To improve the structural strength and welding precision of the frame connections, the industry generally uses plasma arc welding equipment. This welding method has a small heat-affected zone and produces uniform and strong welds, effectively strengthening the toughness and sealing of the pipe connections. This prevents problems such as breakage and deformation in complex outdoor environments, further enhancing the durability and overall structural stability of the tent frame, making it suitable for diverse usage scenarios such as outdoor camping and outdoor work.

[0003] For example, Chinese patent CN118635785B discloses an outdoor tent frame production welding machine, which relates to the field of tent production and processing technology. The machine includes a box body, a working chamber fixedly installed on the top surface of the box body, a door rotatably connected to the front end of the working chamber, and a door rotatably connected to the front end of the box body; a controller, which is fixedly installed on the left side wall of the box body, and a power distribution box fixedly installed on the right side wall of the box body; and a welding robotic arm, which is fixedly installed on the top surface inside the working chamber.

[0004] While the above solution addresses the issue of achieving stable and tight clamping for supports of varying weights and sizes, some shortcomings still require improvement. Currently, traditional plasma arc welding machines generally employ a continuous gas supply mode for their shielding gas circuits. In the skip welding process of tent support welding, when the robotic arm moves the welding head between different weld points, there is a non-arc-initiating idle gap. If the shielding gas is continuously supplied, it not only results in a significant waste of gas resources, substantially increasing production costs and leading to poor economic efficiency, but also the continuous high-flow-rate gas flow easily creates turbulent airflow disturbances in the welding area, resulting in welding defects such as porosity and slag inclusions inside the weld, severely reducing the welding quality and structural connection strength of the tent support. This invention aims to solve the problem of shielding gas waste during arc interruption and displacement. Summary of the Invention

[0005] This invention provides a welding machine for the production of outdoor tent frames, which solves the problem that constantly supplying protective gas not only causes a large amount of ineffective gas source loss but also increases production costs.

The third bevel gear and the fourth bevel gear are meshed together.

[0009] Optionally, the marking assembly includes a fixing block, which is fixedly connected to one side of the air guide tube.

[0010] Optionally, a connecting hose is fixedly connected to the top end of the gas guide tube. One side of the connecting hose passes through the lower mounting plate and is fixedly connected to the lower mounting plate. The connecting hose is connected to the outlet pipe of the argon cylinder. The outlet pipe of the argon cylinder is equipped with a pressure regulator and a gas flow meter.

[0011] Optionally, a first cylinder is fixedly connected to the top of the frame, and a hanging plate is fixedly connected to the output end of the first cylinder. The hanging plate is movably connected to the lower side of the frame through the first cylinder, and the bottom end of the hanging plate is fixedly connected to the top of the robotic arm body.

[0012] Optionally, a shock absorber is fixedly connected between the upper mounting plate and the lower mounting plate, and multiple shock absorbers are provided. The shock absorber is composed of a shock-absorbing spring and a damper, and rubber pads are fixedly connected to the opposite surfaces of the upper mounting plate and the lower mounting plate.

[0013] Optionally, the first clamping assembly includes a first frame, which is fixedly connected to the top of the base and located below the welding head.

[0015] The beneficial effects of the above-described technical solution of the present invention are as follows: 1. By setting up a first motor and an opening and closing mechanism, the output power of the first motor drives the linkage structure to operate, which in turn drives the circular plug in the opening and closing mechanism to rotate synchronously inside the air guide tube. This achieves the intermittent opening and closing of the airflow channel in the air guide tube, realizing the intermittent air supply mode of the protective gas in the spot welding gap. Compared with continuous air supply at all times, this solution uses the rigid linkage of the mechanical structure to simultaneously cut off the air path during the gap of welding head displacement and arc interruption. This effectively reduces the overall protective gas consumption while ensuring sufficient air supply to each welding point. At the same time, it can effectively reduce the turbulence and disturbance caused by continuous high-flow airflow, avoid welding defects such as porosity and slag inclusion caused by airflow interference inside the weld, ensure the regular formation of the tent frame weld, strengthen the structural strength of the frame connection, and adapt to the use needs of complex outdoor environments. 2. By setting up a first motor and a fine-tuning mechanism, the first motor provides power to drive the transmission structure in the fine-tuning mechanism to rotate, causing the welding head to rotate intermittently below the welding machine body. The intermittent rotation of the welding head can make the nozzle rotate evenly, avoiding the nozzle from being subjected to high welding temperatures for a long time when it is stationary. This reduces the wear and deformation of the nozzle due to local overheating, extends the service life of the nozzle, and makes the welding angle of the welding head more uniform, ensuring that the weld thickness at the tent frame welding point is consistent, further improving the precision of the welding process and ensuring the uniform structural strength of each connection of the tent frame.

[0018] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0019] like Figures 1 to 9 As shown, an embodiment of the present invention provides an outdoor tent frame welding machine, including a base 1. A frame 2 is fixedly connected to one side of the top of the base 1. A controller 3 is fixedly installed on the top of the base 1 near the frame 2. A robotic arm body 13 is provided on one side of the bottom of the frame 2. An upper mounting plate 131 is fixedly connected to the lower side of the robotic arm body 13. A lower mounting plate 14 is provided below the upper mounting plate 131. A welding machine body 4 is fixedly connected to the middle of the bottom of the lower mounting plate 14. A first motor 6 is fixedly connected to one side, and a fine-tuning mechanism 7 is provided on the outside of the first motor 6. The welding head 5 is mounted on the bottom of the welding machine body 4 by rotating through the fine-tuning mechanism 7. A gas guide pipe 901 is fixed on the other side of the lower mounting plate 14. The lower end of the gas guide pipe 901 is connected to the protective gas inlet pipe 9. An opening and closing mechanism 8 and a marking component 10 are respectively provided on one side of the fine-tuning mechanism 7. One side of the opening and closing mechanism 8 extends into the gas guide pipe 901. A first clamping component 17 and a second clamping component 18 are also arranged sequentially on the top of the machine base 1.

[0020] like Figure 3 and Figure 7As shown, a disc 702 is fixedly connected to the bottom end of the first rotating rod 701. Transmission gear blocks 703 are fixedly connected to both sides of the disc 702, with three transmission gear blocks 703 on each side. A transmission gear 704 is located near the disc 702 on one side of the welding head 5. The transmission gear blocks 703 mesh with the transmission gear 704. A rotating seat 705 is fixedly connected to the top end of the welding head 5. The transmission gear 704 is fixedly connected to the outside of the rotating seat 705. A docking seat 706 is rotatably connected to one side of the rotating seat 705. The docking seat 706 is fixedly connected to the bottom end of the welding machine body 4. The first motor 6 drives the first rotating rod 701 to drive the disc 702 to rotate synchronously. The transmission gear 703 on the disc 702 alternately meshes with the transmission gear 704 on the outside of the welding head 5, driving the rotating seat 705 to rotate intermittently around the docking seat 706, thereby driving the welding head 5 to complete the angle adjustment slowly. This linkage structure uses a single power source to realize the angle adjustment of the welding head 5, which simplifies the power system design of the equipment, reduces the manufacturing cost and maintenance difficulty of the equipment, avoids long-term heating of a single part of the nozzle of the welding head 5, makes it heat evenly, extends the service life of the welding head 5, and ensures the continuous and stable operation of welding.

[0021] like Figures 4-6As shown, the opening and closing mechanism 8 includes a second rotating rod 801, which is rotatably connected to one side of the air guide tube 901. A plug 802 is fixedly connected to one side of the second rotating rod 801 extending into the air guide tube 901. The plug 802 is rotatably connected to the inside of the air guide tube 901 via the second rotating rod 801. A fan-shaped air guide notch is formed on the cylindrical surface of the plug 802, penetrating its upper and lower end faces. When the plug 802 rotates with the second rotating rod 801 to a preset angle, the fan-shaped air guide notch connects to the air guide tube 901. The upper and lower air passages of the 1-type air passage have rubber patches 803 fixedly connected to the periphery of the plug 802 (excluding the solid part of the fan-shaped air guide notch). A linkage rod 804 is fixedly connected to the middle of the first rotating rod 701. A transmission rod 807 is provided on one side of the linkage rod 804. A first bevel gear 805 is fixedly connected to the middle of the linkage rod 804. A second bevel gear 806 is fixedly connected to one end of the transmission rod 807. The first bevel gear 805 and the second bevel gear 806 mesh to achieve a 90-degree change in transmission direction. The transmission rod 807... A third bevel gear 808 is fixedly connected to the end of the second rotating rod 801 away from the plug 802, and a fourth bevel gear 809 is fixedly connected to the side of the second rotating rod 801 away from the plug 802. The third bevel gear 808 and the fourth bevel gear 809 are meshed together. When the first motor 6 drives the first rotating rod 701 to rotate, it synchronously drives the linkage rod 804 to rotate. The linkage rod 804 transmits power to the second rotating rod 801 through the meshing of the first bevel gear 805, the second bevel gear 806, the third bevel gear 808, and the fourth bevel gear 809, thereby driving the plug. The head 802 rotates inside the gas guide tube 901, realizing the intermittent opening and closing of the airflow channel of the gas guide tube 901. The rubber patch 803 adheres to the inner wall of the gas guide tube 901, which can enhance the sealing performance between the plug 802 and the gas guide tube 901, prevent protective gas leakage, and ensure the airtightness of the gas path. This design realizes the power reuse of protective gas supply control and welding head 5 angle adjustment, without the need for an additional independent drive mechanism, simplifying the equipment structure, realizing intermittent supply of protective gas, reducing gas source waste, and avoiding the impact of a large amount of airflow disturbance on welding quality.

[0022] like Figure 5As shown, the marking component 10 includes a fixing block 101, which is fixedly connected to one side of the air guide tube 901. An infrared sensor 102 is fixedly connected to the middle of the fixing block 101. A rotating block 103 is fixedly connected to the middle of the second rotating rod 801. A light-shielding plate 104 is fixedly connected to one side of the rotating block 103. When the second rotating rod 801 rotates, it drives the rotating block 103 and the light-shielding plate 104 to rotate synchronously. The light-shielding plate 104 will intermittently block the infrared signal of the infrared sensor 102. The infrared sensor 102 transmits the signal change to the controller 3. The operator can monitor the rotation status of the plug 802 in real time through the controller 3 to determine whether the timing of the protective gas on / off is accurate. At the same time, it can also detect faults such as jamming and wear in the transmission structure in a timely manner, which is convenient for the operator to carry out timely maintenance, ensure the normal operation of the opening and closing mechanism 8, and ensure the stable realization of the intermittent gas supply mode of the protective gas.

[0023] like Figure 3 As shown, a connecting hose 902 is fixedly connected to the top end of the gas guide tube 901. One side of the connecting hose 902 passes through the lower mounting plate 14 and is fixedly connected to the lower mounting plate 14. The connecting hose 902 is connected to the outlet pipe of the argon cylinder. The outlet pipe of the argon cylinder is equipped with a pressure regulator and a gas flow meter. The connecting hose 902 is made of flexible material and can be flexibly bent and extended with the movement of the robotic arm body 13, avoiding the gas guide tube 901 from being pulled, bent and damaged due to the movement of the robotic arm. The pressure regulator can adjust the high-pressure protective gas in the argon cylinder to the pressure range required for welding, avoiding the high-pressure gas from directly impacting the welding area and causing airflow turbulence. The gas flow meter can accurately measure the delivery flow of the protective gas, further reducing the ineffective consumption of the gas source.

[0024] like Figures 1-2 As shown, a first cylinder 11 is fixedly connected to the top of the frame 2, and a hanging plate 12 is fixedly connected to the output end of the first cylinder 11. The hanging plate 12 is movably connected to the lower side of the frame 2 through the first cylinder 11, and the bottom end of the hanging plate 12 is fixedly connected to the top of the robotic arm body 13. When the first cylinder 11 is working, it drives the hanging plate 12 to move up and down, thereby driving the robotic arm body 13, the welding machine body 4, and the welding head 5 to adjust their overall height. The distance between the welding head 5 and the tent frame can be flexibly adjusted according to the size and specifications of the tent frame and the height requirements of the welding position, so that the welding head 5 is at the optimal welding height, improving welding accuracy. At the same time, during the workpiece clamping stage, the welding head 5 can be raised to provide sufficient operating space for the workpiece to be picked up, placed, and positioned, improving the convenience of workpiece clamping.

[0025] like Figure 8As shown, a shock absorber 15 is fixedly connected between the upper mounting plate 131 and the lower mounting plate 14, and multiple shock absorbers 15 are provided. The shock absorber 15 is composed of a shock-absorbing spring and a damper. Rubber pads 16 are fixedly connected to the opposite surfaces of the upper mounting plate 131 and the lower mounting plate 14. Through the synergistic effect of the shock absorber 15 and the rubber pads 16, the vibration generated during the operation of the robotic arm body 13 and the high-frequency vibration generated during the operation of the welding machine body 4 can be effectively absorbed, preventing the vibration from being transmitted to the welding head 5, preventing the welding head 5 from shifting due to vibration, and ensuring the continuous and stable operation of the welding work.

[0026] like Figure 9 As shown, the first clamping assembly 17 includes a first frame 171, which is fixedly connected to the top of the base 1 and located below the welding head 5. A second motor 172 is fixedly connected to one side of the first frame 171, and a first bidirectional lead screw 173 is fixedly connected to the output end of the second motor 172. The first bidirectional lead screw 173 is rotatably connected inside the first frame 171. Both sides of the first bidirectional lead screw 173 are threadedly connected to first slide blocks 174. One side of the first slide block 174 is slidably connected inside the first frame 171, and the other side of the first slide block 174 is fixedly connected to a vertical abutment plate 175 for fixing the main frame of the outdoor tent. The second motor 172 drives the first bidirectional lead screw 173 to rotate, driving the first slide blocks 174 on both sides to move synchronously relative to each other along the first frame 171, thereby driving the vertical abutment plates 175 to move closer to each other, thereby clamping and fixing the main frame of the tent frame. The bidirectional lead screw transmission can ensure strong synchronous movement of the first slide blocks 174 on both sides, making the main frame evenly stressed and avoiding deformation of the main frame during clamping.

[0027] like Figure 9As shown, the second clamping assembly 18 includes a second frame 181, which is located at the top of the base 1 and near the first frame 171, and is perpendicular to the first frame 171. A third motor 182 is fixedly connected to one side of the second frame 181, and a second bidirectional lead screw 183 is fixedly connected to the output end of the third motor 182. The second bidirectional lead screw 183 is rotatably connected inside the second frame 181. A second slide block 184 is threaded to both sides of the second bidirectional lead screw 183. One side of the second slide block 184 is slidably connected inside the second frame 181, and a transverse abutment plate 185 is fixedly connected to the other side of the second slide block 184 for fixing. The side frame of the outdoor tent main frame has a second cylinder 186 fixedly connected to the top of the base 1 below the second frame 181. The output end of the second cylinder 186 is fixedly connected to the bottom end of the second frame 181. The third motor 182 drives the second bidirectional lead screw 183 to rotate, which drives the two second slide blocks 184 on both sides to move relative to each other, and drives the transverse contact plate 185 to clamp the side frame of the tent frame. With the cooperation of the first clamping component 17, the main frame and the side frame are accurately positioned and fixed, ensuring that the connection position of the side frame and the main frame is accurate and avoiding misalignment during welding. At the same time, the second cylinder 186 can drive the second frame 181 to move up and down, which can adjust the height of the side frame to be installed, so that the welding position of the side frame and the main frame is on the same horizontal plane.

[0028] The working process of the outdoor tent frame production welding machine provided by this invention is as follows: First, the operator moves the main frame and side frames of the outdoor tent bracket to the designated positions on the base 1. Then, the equipment is started by the controller 3. The second motor 172 in the first clamping assembly 17 starts working, driving the first bidirectional lead screw 173 to rotate. This drives the first slide blocks 174 on both sides to move synchronously relative to each other along the first frame 171, thereby driving the vertical contact plates 175 to move closer together and clamp and fix the main frame of the tent bracket, ensuring that the main frame will not shift during the welding process. At the same time, the third motor 182 in the second clamping assembly 18 starts, driving the second bidirectional lead screw 183 to rotate, causing the second slide blocks 184 on both sides to move relative to each other. The side frames of the tent bracket are clamped by the horizontal contact plates 185. Then, the second cylinder 186 extends and retracts, driving the second frame 181 to move up and down, adjusting the height of the side frames so that the welding positions of the side frames and the main frame are on the same horizontal plane. This achieves the docking and positioning of the main frame and the side frames and prevents misalignment during welding. After positioning, the operator adjusts the output pressure and flow rate of the protective gas according to the specifications and parameters of the tent frame, using the pressure regulator and gas flow meter on the argon gas cylinder outlet pipe, to ensure that the protective gas supply meets the welding requirements. At this time, the connecting hose 902 can be flexibly bent with the subsequent movement of the robotic arm to avoid the gas guide pipe 901 being pulled and damaged, ensuring stable delivery of the protective gas. Then, the first cylinder 11 is started. The extension and retraction of the first cylinder 11 drives the hanging plate 12 to move up and down, thereby driving the robotic arm body 13, the welding machine body 4, and the welding head 5 to adjust the overall height, adjusting the welding head 5 to the optimal welding height, avoiding problems such as welds that are too shallow or too deep due to height deviation. At the same time, the robotic arm body 13 can drive the welding machine body 4 and the welding head 5 to move flexibly. Upon entering the welding stage, the first motor 6 and the welding machine body 4 are started. The first motor 6 outputs power to drive the first rotating rod 701 to rotate synchronously. On one hand, the first rotating rod 701 drives the disc 702 to rotate. The transmission gear 703 on the disc 702 alternately meshes with the transmission gear 704 on the outside of the welding head 5, causing the rotating seat 705 to rotate intermittently around the docking seat 706. This, in turn, drives the welding head 5 to complete continuous fine-tuning operations, ensuring that each part of the nozzle of the welding head 5 corresponds to the welding area, avoiding long-term operation of a single part of the nozzle. To withstand the high welding temperatures and reduce nozzle wear, the first rotating rod 701 drives the linkage rod 804 to rotate. The linkage rod 804 transmits power to the second rotating rod 801 through the meshing of the first bevel gear 805, second bevel gear 806, third bevel gear 808, and fourth bevel gear 809. This drives the plug 802 to rotate inside the air guide tube 901, achieving intermittent opening and closing of the airflow channel in the air guide tube 901. The rubber patch 803 on the periphery of the plug 802 enhances its connection with the air guide tube 901. 1. The sealing of the inner wall prevents the leakage of protective gas and enables intermittent supply of protective gas. Compared with the traditional continuous gas supply mode, it greatly reduces the ineffective loss of protective gas, reduces the gas source cost in industrial production, and avoids the turbulent disturbance caused by continuous large flow of gas. It also reduces defects such as porosity and slag inclusion inside the weld, ensures that the weld is formed regularly, and strengthens the structural strength of the support connection. At the same time, the marking component 10 works synchronously. When the second rotating rod 801 rotates, it drives the rotating block 103 and the light shield 104 to rotate synchronously. The light shield 104 intermittently blocks the infrared signal of the infrared sensor 102 on the fixed block 101. The infrared sensor 102 transmits the signal change to the controller 3. The operator can monitor the rotation status of the plug 802 in real time through the controller 3, judge whether the timing of the on and off of the protective gas is accurate, and promptly detect faults such as jamming and wear of the transmission structure. This facilitates timely maintenance and ensures the stable implementation of the intermittent gas supply mode. When the light shield 104 completely blocks the signal of the infrared sensor 102, it can be determined that the plug 802 is in the closed state. During the welding process, multiple shock absorbers 15 and rubber pads 16 between the upper mounting plate 131 and the lower mounting plate 14 work together to effectively absorb the vibrations generated when the robotic arm body 13 operates and the welding machine body 4 works, preventing the vibrations from being transmitted to the welding head 5 and causing the welding position to shift, thus ensuring that the welding work continues stably.

[0029] The entire welding process does not require multiple independent drive mechanisms. All components work together to solve the technical problems of waste of protective gas and many welding defects in traditional welding machines. It also improves welding accuracy and processing efficiency, adapts to the mass production needs of tent frames of different specifications, and the welded tent frames have strong welds and stable structures, which can meet the needs of use in complex outdoor environments.

[0030] The above description represents the preferred embodiments of the present invention.
