Description

Technical Field

[0001] This application relates to the field of screw welding technology, and more particularly to a screw welding apparatus. Background Technology

[0002] In today's diverse and complex industrial and manufacturing landscape, screws have always played a crucial role as key connectors, permeating every stage from large-scale infrastructure construction to the manufacturing of precision electronic products. However, with the development of the times and the evolution of technology, the inherent limitations of traditional screw connection methods have acted like shackles, severely restricting the improvement of production efficiency and the advancement of product quality, thus strongly spurring the vigorous development of screw welding technology as a revolutionary solution.

[0003] Screws and the workpieces they connect to are independent entities. During assembly, workers must manually align each screw with a screw hole on the workpiece. This process requires not only a high level of skill but is also extremely time-consuming. Especially in large-scale production scenarios, such as the mass installation of doors and windows on construction sites or the batch assembly of electronic product casings on production lines, the cumbersome screw installation process significantly slows down the overall production progress and increases labor costs. Therefore, this patent requires an upgrade and modification based on existing technology. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a screw welding device that overcomes the deficiencies of the prior art. It aims to solve the problem that in the assembly process, workers must manually align the screws one by one with the screw holes on the workpiece. This process not only requires workers to have a high level of operational proficiency, but is also extremely time-consuming.

[0005] To achieve the above objectives, this application provides the following technical solution: a screw welding device, comprising a support frame, the support frame having a C-shaped structure, a hydraulic rod fixedly connected to the top of the support frame, a top clamping mechanism fixedly connected to the bottom of the hydraulic rod, a top clamping block clamped and fixedly located at the middle position of the top clamping mechanism, a top fastening device fixedly connected to the end position of the top clamping block, a top extension rod clamped and fixedly located inside the top fastening device, a top welding head fixedly connected to the end of the top extension rod, a bottom clamping mechanism fixedly connected to the bottom of the support frame, a bottom clamping block clamped and fixedly located inside the bottom clamping mechanism, a bottom fastening device fixedly connected to the end of the bottom clamping block, a bottom extension rod clamped and fixedly located inside the bottom fastening device, a bottom welding head fixedly connected to the top of the bottom extension rod, a welding workpiece fixedly attached to the top of the bottom welding head, a welding bolt inserted into the welding workpiece, the welding bolt penetrating the welding workpiece and then inserted into the bottom welding head.

[0006] By adopting the above technical solution, the welding bolt is inserted into the workpiece during use, and then the bottom of the welding bolt is inserted into the bolt hole. Then, the top clamping mechanism is lowered by controlling the bottom extension rod, which drives the top fastening device on the outside of the top clamping mechanism to lower. The top fastening device drives the top extension rod of the internal clamping mechanism to lower until the top welding head is in contact with the top of the welding bolt. The top welding head and the bolt hole are heated, thereby heating the welding bolt and the workpiece until fusion occurs between the welding bolt and the workpiece. Then, the hydraulic rod is controlled to retract, thereby driving the top welding head to rise as a whole. At this time, the welding between the welding bolt and the workpiece is completed.

[0007] As a preferred technical solution of this application, a heating device is fixedly connected to one side of the back of the support frame, a top heating line is provided at the top of the top extension rod, one end of the top heating line passes through the top extension rod and is fixedly connected to the top welding head, and the other end of the top heating line is fixedly connected to the heating device.

[0008] By adopting the above technical solution, the heating device drives the top and bottom welding heads to heat through the top heating line and the bottom heating line, thereby realizing the welding between the welding bolt and the welding workpiece.

[0009] As a preferred technical solution of this application, the top clamping mechanism and the bottom clamping mechanism have the same structure. The top clamping mechanism adopts an upper and lower clamping block structure to clamp the top clamping block inside. The top clamping mechanism is internally threaded with a fastening bolt.

[0010] By adopting the above technical solution, the clamping of the top clamping block by the upper and lower clamping blocks inside the top clamping mechanism can be controlled by the setting of the fastening bolt. At the same time, when the fastening bolt is loosened, the top clamping block can be slid back and forth to adjust the appropriate welding position according to the requirements. Then the fastening bolt is tightened to fix the position of the top clamping block.

[0011] As a preferred technical solution of this application, the top fastening device and the bottom fastening device have the same structure. The top fastening device adopts a front clamping block and a rear clamping block, and the front clamping block and the rear clamping block are internally threaded with clamping bolts.

[0012] By adopting the above technical solution, the top extension rod is secured by clamping bolts. Loosening the clamping bolts controls the up-and-down movement of the top extension rod, thus adapting to different welded parts. Then, tightening the clamping bolts secures the top extension rod.

[0013] As a preferred technical solution of this application, the top extension rod and the bottom extension rod have the same structure, and the top extension rod adopts an S-shaped structure.

[0014] By adopting the above technical solution, the top extension rod can be controlled to rotate around the clamping position by loosening the clamping bolts. The S-shaped structure can adapt to welding tasks in special positions.

[0019] As a preferred technical solution of this application, the surfaces of the top welding head and the bottom welding head are both coated with a high-temperature resistant and antioxidant coating.

[0020] By adopting the above technical solution, the coating is made of nano-ceramic material. Under long-term high-temperature welding environment, this coating can effectively prevent oxidation and corrosion of the welding head, extend the service life of the welding head, and reduce the cost increase caused by frequent replacement of the welding head.

In use, the welding bolt 17 is inserted into the welding workpiece 18, and then the bottom of the welding bolt 17 is inserted into the bolt hole 14. Then, the bottom extension rod 13 controls the top clamping mechanism 4 to descend, which drives the top fastening device 6 on the outside of the top clamping mechanism 4 to descend. The top fastening device 6 drives the top extension rod 7 inside to descend until the top welding head 9 is attached to the top of the welding bolt 17. The top welding head 9 and the bolt hole 14 are heated, which causes the welding bolt 17 and the welding workpiece 18 to be heated until the welding bolt 17 and the welding workpiece 18 are fused together. Then, the hydraulic rod 3 is controlled to retract, which drives the top welding head 9 to rise as a whole. At this time, the welding between the welding bolt 17 and the welding workpiece 18 is completed.

[0030] In this embodiment, as Figure 1 - Figure 3 As shown, a heating device 2 is fixedly connected to one side of the back of the support frame 1. A top heating line 8 is provided at the top of the top extension rod 7. One end of the top heating line 8 passes through the top extension rod 7 and is fixedly connected to the top welding head 9. The other end of the top heating line 8 is fixedly connected to the heating device 2. A bottom heating line 16 is provided at one end of the bottom of the bottom extension rod 13. One end passes through the bottom extension rod 13 and is fixedly connected to the bottom welding head 15. The other end of the bottom heating line 16 is fixedly connected to the heating device 2. The heating device 2 drives the top welding head 9 and the bottom welding head 15 to be heated through the top heating line 8 and the bottom heating line 16, thereby realizing the welding between the welding bolt 17 and the welding workpiece 18.

[0031] In this embodiment, as Figure 1 - Figure 3As shown, the top clamping mechanism 4 and the bottom clamping mechanism 10 have the same structure. The top clamping mechanism 4 uses an upper and lower clamping block structure to clamp the top clamping block 5 inside. The top clamping mechanism 4 has a threaded connection with a fastening bolt. The setting of the fastening bolt can control the clamping of the top clamping block 5 by the upper and lower clamping blocks inside the top clamping mechanism 4. At the same time, when the fastening bolt is loosened, the top clamping block 5 can slide back and forth to adjust to a suitable welding position as needed. Then the fastening bolt is tightened to fix the position of the top clamping block 5.

[0032] In this embodiment, as Figure 1 - Figure 3 As shown, the top fastening device 6 and the bottom fastening device 12 have the same structure. The top fastening device 6 adopts a front clamping block and a rear clamping block. The front clamping block and the rear clamping block are internally threaded with clamping bolts. The top extension rod 7 is fastened by clamping bolts. The top extension rod 7 can be moved up and down by loosening the clamping bolts to adapt to different welded parts. Then, the top extension rod 7 is fastened by tightening the clamping bolts.

[0033] In this embodiment, as Figure 1 - Figure 3 As shown, the top extension rod 7 and the bottom extension rod 13 have the same structure. The top extension rod 7 adopts an S-shaped structure. By loosening the clamping bolt, the top extension rod 7 can be controlled to rotate around the clamping position. The S-shaped structure can adapt to welding tasks in special positions.

[0034] In this embodiment, as Figure 1 - Figure 3 As shown, the bottom welding head 15 has a bolt hole 14 at the top position, and the welding workpiece 18 has a welding hole 19 inside. The welding bolt 17 passes through the welding hole 19 and is inserted into the bolt hole 14. The setting of the bolt hole 14 enables the welding bolt 17 to fit the bolt head against the top of the welding workpiece 18 after passing through it, thereby ensuring the welding work between the welding bolt 17 and the welding workpiece 18.

[0035] In this embodiment, as Figure 1 - Figure 3 As shown, the top extension rod 7 and the bottom extension rod 13 are provided with scale markings with an accuracy of 0.1 mm. During operation, the operator can accurately and quickly adjust to the appropriate welding spacing by observing the scale markings.

[0036] In this embodiment, as Figure 1 - Figure 3As shown, the surfaces of the top welding head 9 and the bottom welding head 15 are coated with a high-temperature resistant and anti-oxidation coating. This coating is made of nano-ceramic material. Under long-term high-temperature welding environment, this coating can effectively prevent the welding head from oxidizing and corroding, extend the service life of the welding head, and reduce the cost increase caused by frequent replacement of welding heads.

[0037] Working principle: Align the welding bolt 17 with the welding hole 19 of the workpiece 18 and insert it through the workpiece 18. Then, accurately insert the bottom of the welding bolt 17 into the bolt hole 14 at the top of the bottom welding head 15. Loosen the fastening bolt inside the top clamping mechanism 4, allowing the top clamping block 5 to slide back and forth within the top clamping mechanism 4. Adjust the top clamping block 5 to a suitable position according to the actual welding position requirements, then tighten the fastening bolt to fix the position of the top clamping block 5. Loosen the clamping bolt in the top fastening device 6. The top extension rod 7 is controlled by operating the bottom extension rod 13 to move in a suitable direction, such as up and down, to adapt to the height of the workpiece 18 and the welding bolt 17, ensuring that the top welding head 9 is accurately aligned with the top of the welding bolt 17. Furthermore, for special welding positions, the S-shaped structure of the top extension rod 7 can be utilized; after loosening the clamping bolt, the top extension rod 7 can be rotated around the clamping position to achieve the appropriate welding angle. Simultaneously, the operator can precisely adjust the welding angle by observing the scale markings on the surface of the top extension rod 13. After adjusting the distance between the top welding head 9 and the bottom welding head 15 to achieve the optimal welding distance, tighten the clamping bolts to fix the position of the top extension rod 7. Control the bottom extension rod 13 to drive the top clamping mechanism 4 to descend as a whole, which in turn causes the top fastening device 6 on the outside of the top clamping mechanism 4 to descend accordingly. The top fastening device 6 drives the internally clamped top extension rod 7 to descend until the top welding head 9 is tightly attached to the top of the welding bolt 17. Then, start the heating device 2. The heating device 2 controls the top through the top heating line 8 and the bottom heating line 16. The welding head 9 and the bottom welding head 15 are heated. The welding bolt 17 and the welding workpiece 18 are gradually heated under the heat of the welding head until the welding bolt 17 and the welding workpiece 18 are fused together, completing the welding operation. After the welding is completed, the hydraulic rod 3 is controlled to retract. The hydraulic rod 3 will drive the top clamping mechanism 4 and the top welding head 9 connected to it to rise as a whole, so that it leaves the area of ​​the welded workpiece. At this time, the welding work between the welding bolt 17 and the welding workpiece 18 is completed. The welded workpiece can be removed from the device for subsequent processing.
