Description

Technical Field

[0001] This utility model relates to the field of swing arm welding machines, and in particular to an automatic feeding swing arm welding machine. Background Technology

[0002] A stud welding machine is a device used to weld metal studs (weld nails) onto metal workpieces. It heats the contact points between the stud and the workpiece using an electric current, causing them to melt rapidly and bond together to form a strong welded joint. Stud welding machines are commonly used in the automotive, electronics, construction, and other industries requiring stud welding.

[0003] During use, the inventors discovered that in the existing technology, the nail welding machine uses a dual-axis method, which adjusts the position of the welding head to weld nails by positioning in a Cartesian coordinate system. However, in order to ensure that the workpiece is completely within the nail-welding range, the maximum stroke of the horizontal and vertical axes of the traditional nail welding machine must be greater than the table area, which results in a higher mechanical structure cost for the traditional nail welding machine. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies.

[0005] To solve the above technical problems, this utility model provides an automatic feeding swing arm welding nail machine, comprising: a support frame, a table fixedly connected to the upper surface of the support frame, a baffle fixedly connected to the side of the support frame, a connecting frame fixedly connected to the upper surface of the support frame, a mounting base installed on the upper end of the table frame, a nail feeding assembly installed on the upper surface of the mounting base, a connecting shell fixedly connected to one end of the nail feeding assembly, a pushing assembly installed inside the nail feeding assembly, a conveying pipe connected to the outside of the pushing assembly, the other end of the conveying pipe connected to the welding head, a base installed on the upper surface of the table frame, a reducer installed inside the base, a connecting platform installed at the output end of the reducer, a slide body installed inside the connecting platform, and the connecting platform being close to... A sliding table guide plate is installed on one side of the nail feeding assembly. A conduit is installed on the upper surface of the sliding table guide plate and mounted on the table surface. A drag chain is installed on the upper surface of the sliding table body. A servo motor is installed at one end of the sliding table body. A mounting plate is installed at the end of the sliding table body away from the servo motor. A linear guide rail is installed on the side of the mounting plate away from the sliding table body. A first cylinder is installed at the upper end of the mounting plate. A slider is installed at the output end of the first cylinder and is slidably connected to the linear guide rail. A second cylinder is installed on the side of the slider away from the mounting plate. A welding head is installed at the output end of the second cylinder. A feed pipe is installed on one side of the slider. A mounting bracket is installed on the upper surface of the table surface, and a control component is installed at the upper end of the mounting bracket.

[0006] The aforementioned components achieve the following effect: When welding nails onto an object, the reducer is activated, causing the connecting table and slide body to rotate, thus facilitating the angle adjustment of the entire welding arm. The welding arm is then aligned with the nail feeding assembly at the same level. The servo motor is then activated to move the slide body on the connecting table, facilitating the adjustment of the welding head position. The slide body aligns the feed pipe with the nail feeding assembly, and the first cylinder is activated to move the slider on the linear guide surface. The slider moves the second cylinder, feed pipe, and welding head, facilitating height adjustment of the welding head. The feed pipe is then connected to the nail feeding assembly to feed the nail. After nail feeding is complete, the welding arm is reset, and the second cylinder is activated to weld the nail.

[0007] Preferably, the linear guide has a rectangular cross-section and is made of stainless steel.

[0008] The effect achieved by the above components is that the linear guide can limit the slider and prevent the slider from deviating during use.

[0009] Preferably, the conduit is a corrugated pipe or a plastic pipe.

[0010] The effect achieved by the above components is that the corrugated pipe can facilitate the adjustment of the conduit and prevent the conduit from bending or breaking during use.

[0011] Preferably, the baffle has a rectangular cross-section and is made of stainless steel.

[0012] The effect achieved by the above components is that the stainless steel material can increase the service life of the baffle and prevent the baffle from rusting during use.

[0013] Preferably, the mounting bracket is a titanium alloy bracket, and the cross-section of the mounting bracket is circular.

[0014] The effect achieved by the above components is that the titanium alloy material can increase the service life of the mounting bracket and prevent damage to the mounting bracket during subsequent use.

[0015] Preferably, the feed pipe has a circular cross-section and is made of plastic.

[0016] The effects achieved by the above components are: the plastic material is relatively inexpensive, reducing the manufacturing cost of the connecting pipe, and it can be easily replaced.

[0017] Preferably, the reducer is a harmonic reducer.

[0018] Preferably, the linear guide is a ball-bearing linear guide.

[0019] Compared with related technologies, the automatic feeding swing arm welding nail machine provided by this utility model has the following beneficial effects:

[0020] This invention provides an automatic feeding swing-arm stud welding machine, a device that uses polar coordinate positioning to fix studs onto workpieces via welding. It is commonly used in metal surface treatment and joining applications. Its main principle is to control the polar angle of the polar coordinate system via a servo motor reducer (slide table swing arm), and to control the polar diameter of the polar coordinate system via the slide table for precise positioning and welding operations, enabling efficient stud addition. The swing-arm stud welding machine offers high precision, efficiency, and flexibility. This structure uses polar coordinate positioning instead of the traditional Cartesian coordinate system for driving the welding head, saving the need for the traditional dual axes of the stud welding machine. While still capable of welding studs to workpieces, it also reduces mechanical structure costs. Attached Figure Description

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figures 1 to 4This utility model provides an automatic feeding swing arm welding nail machine, comprising: 1. An automatic feeding swing arm welding nail machine, comprising: a support 1, a table 3 fixedly connected to the upper surface of the support 1, a baffle 2 fixedly connected to the side of the support 1, a connecting frame 10 fixedly connected to the upper surface of the support 1, a mounting base 11 installed on the upper end of the table 3, a nail feeding assembly 12 installed on the upper surface of the mounting base 11, a connecting shell 9 fixedly connected to one end of the nail feeding assembly 12, a pushing assembly 24 installed inside the nail feeding assembly 12, a conveying pipe connected to the outside of the pushing assembly 24, and the other end of the conveying pipe connected to the welding head, a base 6 installed on the upper surface of the table 3, a reducer 13 installed inside the base 6, a connecting platform 20 installed at the output end of the reducer 13, a sliding table body 19 installed inside the connecting platform 20, and the connecting platform 20 being close to the feeding... A sliding table guide plate 8 is installed on one side of the nail assembly 12. A conduit 7 is installed on the upper surface of the sliding table guide plate 8. The conduit 7 is installed on the table surface 3. A drag chain 16 is installed on the upper surface of the sliding table body 19. A servo motor 15 is installed at one end of the sliding table body 19. A mounting plate 18 is installed at the end of the sliding table body 19 away from the servo motor 15. A linear guide rail 23 is installed on the side of the mounting plate 18 away from the sliding table body 19. A first cylinder 14 is installed at the upper end of the mounting plate 18. A slider 25 is installed at the output end of the first cylinder 14. The slider 25 is slidably connected to the linear guide rail 23. A second cylinder 21 is installed on the side of the slider 25 away from the mounting plate 18. A welding head 22 is installed at the output end of the second cylinder 21. A feed pipe 17 is installed on one side of the slider 25. A mounting bracket 4 is installed on the upper surface of the table surface 3. A control assembly 5 is installed at the upper end of the mounting bracket 4. When it is necessary to weld nails onto an object, the reducer 13 is started to rotate, which drives the connecting table 20 and the slide body 19 to rotate, thereby facilitating the adjustment of the angle of the entire welding arm. Then, the welding arm and the nail feeding assembly 12 are aligned at the same level, and the servo motor 15 is started to move, which drives the slide body 19 to move on the connecting table 20, thereby facilitating the adjustment of the position of the welding head 22. Then, the slide body 19 aligns the feed pipe 17 with the nail feeding assembly 12, and then the first cylinder 14 is started to move, which drives the slider 25 to slide on the surface of the linear guide rail 23. The slider 25 drives the second cylinder 21, the feed pipe 17 and the welding head 22 to move, thereby facilitating the height adjustment of the welding head 22. Then, the feed pipe 17 is connected to the nail feeding assembly 12 to feed the nail. After the nail feeding is completed, the welding arm is reset, and then the second cylinder 21 is started to weld the nail. The linear guide rail 23 has a rectangular cross-section and is made of stainless steel. The linear guide rail 23 can limit the slider 25 to prevent it from deviating during use. The conduit 7 is a corrugated pipe made of plastic. The corrugated pipe allows for easy adjustment of the conduit 7 and prevents it from bending or breaking during use. The baffle 2 has a rectangular cross-section and is made of stainless steel.The stainless steel material increases the service life of the baffle 2 and prevents it from rusting during use. The mounting bracket 4 is made of titanium alloy and has a circular cross-section. The titanium alloy material also increases the service life of the mounting bracket 4 and prevents it from being damaged during use. The feed pipe 17 has an annular cross-section and is made of plastic. Plastic is a relatively inexpensive material, reducing the manufacturing cost of the connecting pipes and allowing for easy replacement.

[0029] The working principle of the automatic feeding swing arm welding machine provided by this utility model is as follows: When welding nails to an object, the reducer 13 is controlled to operate by converting between the rectangular coordinate system and the polar coordinate system. The reducer 13 drives the connecting table 20 and the slide body 19 to rotate, thereby facilitating the angle control of the entire welding arm and also realizing the control of the polar angle of the welding head 22. By controlling the movement of the servo motor 15, the servo motor 15 drives the slide body 19 to move on the connecting table 20, thereby facilitating the adjustment of the position of the welding head 22, that is, controlling the polar diameter of the welding head 22. By adopting the above operation, the position of the welding head 22 can be adjusted using the principle of polar coordinate system positioning, thereby achieving the purpose of positioning the welding nail on the workpiece for welding. Then, the slide body 19 aligns the feed pipe 17 with the nail feeding assembly 12, and then the first cylinder 14 is activated to move it. The first cylinder 14 drives the slider 25 to slide on the surface of the linear guide rail 23. The slider 25 drives the second cylinder 21, the feed pipe 17 and the welding head 22 to move, thereby facilitating the height adjustment of the welding head 22. Then, the feed pipe 17 is connected to the nail feeding assembly 12 to feed the nail. After the nail feeding is completed, the welding arm is reset, and then the second cylinder 21 is activated to weld the nail. The linear guide rail 23 can limit the slider 25 to prevent the slider 25 from deviating during use. The corrugated pipe can facilitate the adjustment of the conduit 7 and prevent the conduit 7 from bending or breaking during use. The stainless steel material can increase the service life of the baffle 2 and prevent the baffle 2 from rusting during use. The titanium alloy material can increase the service life of the mounting bracket 4 and prevent the mounting bracket 4 from being damaged during use. The plastic material is relatively inexpensive, reducing the manufacturing cost of the connecting pipe and making it easy to replace.
