Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts processing, and particularly to a welding device for automotive parts production. Background Art

[0002] Automotive parts are the parts used for assembly. Among them, the sheet metal parts of the vehicle are the most used parts in vehicle manufacturing and maintenance. The connection methods between sheet metal parts and other parts can be divided into plug-in, welding, threaded connection, etc. Sometimes, according to the usage requirements, the two methods of welding and threaded connection are used in combination. Therefore, when producing automotive parts (sheet metal parts), nuts are welded to the sheet metal parts, and the screw holes of the nuts are aligned and communicated with the holes of the sheet metal parts, so as to perform threaded connection operations with other parts subsequently.

[0003] However, in the actual working process, the existing welding tooling structure is relatively simple, lacking measures to align the nut holes with the holes of the sheet metal parts, resulting in misalignment deviation of the holes during welding, which seriously affects the welding effect. At the same time, the sheet metal parts mostly exist in irregular shapes, so most of the tooling structures in the existing technology cannot effectively limit and fix the sheet metal parts, making the welding effect unable to be effectively guaranteed. Summary of the Invention

Detailed Embodiment

[0022] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following detailed description of the specific embodiments of the present invention will be made in conjunction with the accompanying drawings of the specification.

[0023] In the following description, many specific details are set forth to facilitate a thorough understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below. Embodiment

[0024] Referring to Figures 1 to 8 , which is an embodiment of the present invention, including a welding device for automotive parts production, including a base 1, an oil delivery system 2 disposed on the base 1, a drive unit 3 disposed on the base 1, and the oil delivery system 2 is in communication with the drive unit 3. A plurality of positioning frames 4 connected to the side of the drive unit 3, and a docking component 5 horizontally inserted into the side of the drive unit 3. The oil delivery system 2 is a common hydraulic oil supply system in the prior art. Through communication with the drive unit 3, it can perform oil injection or oil pumping operations on the drive unit 3. Referring to Figure 6 , the drive unit 3 includes a fixed cylinder block 31, a limit frame 32 disposed on the side of the cylinder block 31 and having a cross structure, a telescopic cavity 33 opened in each branch of the cross structure of the limit frame 32, and a transfer cavity 34 opened at the central position of the cylinder block 31, and the transfer cavity 34 is in communication with the telescopic cavity 33. When the oil delivery system 2 injects hydraulic oil into the drive unit 3, the hydraulic oil can be injected into the telescopic cavity 33 through the transfer cavity 34, thereby driving the positioning frame 4 installed in the telescopic cavity 33 to act. Referring to Figure 4 And Figure 7, the positioning frame 4 includes a horizontally arranged cross bar 41, a connecting rod 42 vertically arranged at the end of the cross bar 41, a telescopic shaft 43 connected to the side of the connecting rod 42, and the telescopic shaft 43 is inserted into the telescopic cavity 33, and a limiting component 44 arranged at the outer end of the cross bar 41. The limiting component 44 is vertically arranged at the outermost end of the cross bar 41 and can limit the object sleeved on the cross bar 41 in the horizontal direction. Since the telescopic shaft 43 extends into the telescopic cavity 33, when hydraulic oil is injected into the telescopic cavity 33, the hydraulic oil can push the telescopic shaft 43 to perform an action of extending vertically outward from the telescopic cavity 33. The extended telescopic shaft 43 drives the cross bar 41 to move vertically synchronously through the connecting rod 42. The four groups of positioning frames 4 are inserted into the telescopic cavities 33 on the cross-shaped branches of the limiting frame 32 through the corresponding telescopic shafts 43. Therefore, the four groups of positioning frames 4 can extend from their respective telescopic cavities 33 in the same and synchronous manner. At this time, the four groups of positioning frames 4 can form a synchronous outward diffusion phenomenon. Refer to Figure 5 It can be seen that for the four groups of positioning frames 4 that diffuse outward synchronously, their outermost sides are always within the range of the same circular ring, and the distance from each group of positioning frames 4 to the center of the circular ring is the same. If the holes of the nut 6 or the sheet metal part 7 are sleeved on the four groups of positioning frames 4, the four groups of positioning frames 4 that expand outward can abut against the inner walls of the screw holes of the nut 6 or the holes of the sheet metal part 7 through their outer walls, so that the centers of the two coincide with the center of the circular ring formed by the four groups of positioning frames 4 on the same axis line, thereby realizing the centering operation of the two, ensuring that the centers of the two objects being butted are on the same axis line, effectively avoiding the occurrence of misalignment and skew phenomena, improving the butting accuracy. At the same time, the four groups of outwardly expanding positioning frames 4 can apply a limiting and fixing abutting force to the nut 6 and the sheet metal part 7 in the circumferential direction, realizing the limiting and fixing of the two, preventing the two from moving during the welding process, and ensuring the welding effect; Refer to Figure 4 And Figure 8 , the butting component 5 includes an extension shaft 51 horizontally inserted into the cylinder block 31, a push block 52 arranged at the outer end of the extension shaft 51 and integrally in a cross-shaped cone shape, and the four sides of the cross-shaped cone of the push block 52 correspondingly extend into the gaps between every two groups of positioning frames 4 and are distributed alternately with the positioning frames 4, and a sealing block 53 arranged at the other end of the extension shaft 51. The extension shaft 51 can move horizontally on the side of the driving unit 3, and the horizontally moving extension shaft 51 can drive the push block 52 to displace synchronously. At this time, if the nut 6 is sleeved on the positioning frame 4, the push block 52 will push the nut 6 to move horizontally, so that the nut 6 approaches and abuts against the sheet metal part 7. Thus, while the positioning frame 4 performs the centering operation, the automatic butting operation of the nut 6 and the sheet metal part 7 is realized, further ensuring the butting accuracy. And the conical push block 52, through its conical appearance, can adaptively match nuts 6 with different inner diameters, and by inserting into the inner diameter of the nut 6, while pushing, it performs a centering operation again through its conical outer wall, further ensuring the accuracy.

[0025] Furthermore, referring to Figure 4 , a main cavity 35 is formed inside the cylinder block 31, and one end of the extension shaft 51 where the sealing block 53 is installed extends into the main cavity 35. At the same time, the diameter of the sealing block 53 matches the inner diameter of the main cavity 35. A delivery pipe 36 is opened downward at one end of the cylinder block 31, and the upper and lower ends of the delivery pipe 36 are respectively communicated with the transfer cavity 34 and the oil delivery system 2. The oil delivery system 2 can deliver hydraulic oil into the transfer cavity 34 and the main cavity 35 through the delivery pipe 36. The structure formed by the matching of the sealing block 53 and the main cavity 35 enables the two to cooperate to form a piston structure, and thus can realize the stretching or retracting operation of the docking component 5 by sucking hydraulic oil.

[0026] Furthermore, referring to Figure 4 , a secondary pipe 37 is horizontally communicated with the side surface of the delivery pipe 36, and one end of the secondary pipe 37 is communicated with the main cavity 35. The connection position of the delivery pipe 36 and the secondary pipe 37 has a flared structure, and the smaller end of the flare is connected to the delivery pipe 36. Due to the special structure of the flare, the hydraulic oil flowing into the delivery pipe 36 will flow into the transfer cavity 34 more smoothly than into the secondary pipe 37. Therefore, the positioning frame 4 inserted into the limit frame 32 will give priority to the centering and alignment work, and then the docking component 5 inserted into the main cavity 35 will perform the docking operation.

[0027] Furthermore, referring to Figure 4 and Figure 7 , the connecting rod 42 is arranged parallel to the vertical direction of the telescopic shaft 43, and the ends of the two are at the same horizontal height. The cross bar 41 is horizontally connected to the end of the telescopic shaft 43. A limit piece matching the inner diameter of the telescopic cavity 33 is arranged at the end of the telescopic shaft 43. The limit piece matching the telescopic cavity 33 enables the telescopic shaft 43 and the telescopic cavity 33 to form a piston structure, and thus realizes the stretching or retracting action of the telescopic shaft 43 in the telescopic cavity 33 by sucking hydraulic oil.

[0028] Among them, referring to Figure 3 and Figure 4The outer end of the cross bar 41 is provided with an empty slot for installing the limit assembly 44, and the limit assembly 44 includes a limit block 441 vertically plugged into the outer end of the cross bar 41, an insertion shaft 442 arranged below the limit block 441, and the insertion shaft 442 extends downward to the outside of the cross bar 41, a magnetic block 443 arranged at the lower end of the insertion shaft 442, and the magnetic block 443 is an isosceles triangle structure, and a spring 444 sleeved on the insertion shaft 442, and the two ends of the spring 444 are respectively abutted against the empty slot and the limit block 441 opened in the cross bar 41, and the magnetic block 443 is composed of a magnet. Four groups of limit assemblies 44 are correspondingly arranged on the four groups of cross bars 41. Under normal conditions, the four groups of cross bars 41 are embraced together. At this time, the four groups of magnetic blocks 443 are under the action of magnetic force. At this time, the force of the magnetic blocks 443 adsorbing each other is greater than the elastic force of the spring 444, thereby compressing the spring 444 so that the limit block 441 shrinks in the cross bar 41, and the shrinking limit assembly 44 can avoid affecting the sheet metal 7 or the nut 6 sleeved on the positioning frame 4, and when the four groups of positioning frames 4 expand outward and move away, the magnetic attraction between the magnetic blocks 443 disappears. At this time, the spring 444 elastically supports the limit block 441 to push it upward, so that the limit block 441 is vertically arranged at the end of the cross bar 41. The vertically arranged limit block 441 can form a horizontal limit on the sheet metal 7, forming a thrust opposite to that when the docking component 5 pushes the nut 6 close to the sheet metal 7, thereby preventing the sheet metal 7 from falling off during the docking process with the nut 6.

[0029] Further, see Figure 1 A slide rail 11 is provided on the base 1, and a slide table 12 is slidably connected to the slide rail 11, and the drive unit 3 is fixedly installed on the slide table 12. A base 13 is slidably provided on the side of the base 1. The slide rail 11 and the slide table 12 cooperate to form an electric slide structure, which can adjust the height position of the rotating shaft to better meet the working requirements. The base 13 can slide back and forth, which is convenient for adjusting the position of the sheet metal part 7 to further meet the use requirements.

[0030] Further, see Figure 1 The oil delivery system 2 includes an oil pump 21 arranged on the base 1, an oil tank 22 connected to one side of the oil pump 21, and an oil pipe 23 connected between the oil pump 21 and the drive unit 3. The oil pump 21 can transport the hydraulic oil in the oil tank 22 into the drive unit 3 through the oil pipe 23, or reversely extract the hydraulic oil in the drive unit 3 from the oil pipe 23 to the oil tank 22.

[0031] During use, combine Figure 4, the nut 6 is sleeved on the positioning frame 4. Subsequently, the positioning frame 4 in the gathered state is docked with the sheet metal hole of the sheet metal part 7. Then, hydraulic oil is injected into the drive unit 3 through the oil delivery system 2 for operation. The hydraulic oil sequentially enters the transfer cavity 34 and the auxiliary pipe 37 through the delivery pipe 36. The hydraulic oil entering the transfer cavity 34 pushes the telescopic shafts 43 in the four telescopic cavities 33 to move outward synchronously, thereby causing the four positioning frames 4 to expand outward synchronously. The limit components 44 at the ends of each positioning frame 4 extend outward correspondingly. The four positioning frames 4 that expand outward synchronously can achieve the centering operation of the nut 6 and the sheet metal part 7, ensuring that the centers of the two docked parts are on the same axis, effectively avoiding the occurrence of misalignment and skew phenomena, improving the docking accuracy, and ensuring the welding effect; The hydraulic oil entering the auxiliary pipe 37 flows into the main cavity 35, and then drives the extension shaft 51 to extend outward by pushing the sealing block 53. The extension shaft 51 that extends outward pushes the nut 6 through the push block 52 and makes it abut against the sheet metal part 7. By horizontally pushing the nut 6 and the sheet metal part 7 closer to each other, the parts to be welded of the two are made to abut together, facilitating the subsequent welding operation and realizing the automatic docking function, thereby improving the work efficiency; During the docking process, there is no need to additionally fix the sheet metal part 7. It is only necessary to cooperate with the push block 52 and the limit component 44 to clamp and fix the position to be welded, avoiding the problem of being unable to effectively fix special-shaped sheet metal parts, ensuring the connection stability between the nut 6 and the sheet metal part 7, and further ensuring the welding effect.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
