[0003] The patent application with the application number CN202122221791.9 discloses a welding device for processing hydraulic cylinder fittings, including a workbench. Two symmetrically arranged support seats are fixed at the bottom of the workbench. A through groove is formed through the workbench. Two symmetrically arranged U-shaped moving frames are slidably connected in the through groove. A bidirectional lead screw is spirally connected to the two U-shaped moving frames below the through groove.

A first arc-shaped plate 2 and a second arc-shaped plate 4 are fixedly connected to the top of the workbench 1. A first annular internal gear disk 5 is fixedly connected to the outer surface of the first arc-shaped plate 2, and a second annular internal gear disk 7 is fixedly connected to the outer surface of the second arc-shaped plate 4. A fixed cleaning mechanism 3 is fixedly connected to the outer surface of the workbench 1. A slag removal welding mechanism 6 and an auxiliary cleaning mechanism 8 are rotatably connected to the inner surfaces of the first annular internal gear disk 5 and the second annular internal gear disk 7. It also includes:

[0044] The fixed cleaning mechanism 3 includes a fixing component 3001. The fixing component 3001 includes a first arc-shaped column 301. The first arc-shaped column 301 is fixedly connected to the outer surface of the workbench 1. A first hydraulic pump 302 is fixedly connected to the first arc-shaped column 301 through a through hole opened inside. The output end of the first hydraulic pump 302 is fixedly connected to a first clamping plate 303. A first sliding rod 304 is fixedly connected to the lower surface of the first clamping plate 303. A first screw rod 305 is rotatably connected to the inside of the workbench 1. A first slider 306 is threadedly connected to the outer surface of the first screw rod 305. A first connecting rod 307 is fixedly connected to the top of the first slider 306. A second hydraulic pump 308 is fixedly connected to the inner surface of the first connecting rod 307. The output end of the second hydraulic pump 308 is fixedly connected to a second clamping plate 309. A first scraping plate 310 is fixedly connected to the outer surface of the first slider 306. The first clamping plate 303 and the second clamping plate 309 are used to clamp the surface of the hydraulic cylinder.

[0045] The fixed impurity removal mechanism 3 includes an impurity removal component 3002. The impurity removal component 3002 includes a clamping block column 313. The clamping block column 313 is slidably connected to the inner surfaces of the first annular internal gear disc 5 and the second annular internal gear disc 7. A second sliding rod 311 is slidably inserted into the interior of the clamping block column 313. A second arc-shaped column 312 is fixedly connected to the bottom of the second sliding rod 311. A brush head 314 is fixedly connected to the outer surface of the second arc-shaped column 312. A friction plate 315 is clamped inside the second arc-shaped column 312. A first gear motor 316 is fixedly connected to the interior of the clamping block column 313. A first spring 317 is fixedly connected to the outer surface of the clamping block column 313. The brush head 314 and the friction plate 315 are used for removing impurities from the surface of the hydraulic cylinder.

[0046] The first sliding rod 304 is slidably connected to the first arc-shaped column 301. The first slider 306 is slidably connected to the workbench 1. The lower surface of the first scraper 310 is in contact with the upper surface of the workbench 1. The first scraper 310 is used for cleaning the surface of the workbench 1. The top of the first spring 317 is fixedly connected to the outer surface of the second sliding rod 311. The first gear motor 316 meshes with the inner surfaces of the first annular internal gear disc 5 and the second annular internal gear disc 7. The first gear motor 316 is used to drive the impurity removal component 3002 to rotate. The clamping position of the second clamping plate 309 is any position where the outer surface of the second clamping plate 309 does not contact the outer surface of the first arc-shaped plate 2 when the surface of the hydraulic cylinder to be welded needs to contact the surface of another hydraulic pump to be welded. The symmetric arrangement of the second clamping plate 309 and the cooperation with the first clamping plate 303 form a space triangle, which plays a positive role in clamping the surface of the hydraulic cylinder. The first scraper 310 cleans the upper surface of the workbench 1, so that the movement of the first slider 306 is not affected, and through the sliding connection between the first slider 306 and the workbench 1, the first screw rod 305 does not directly bear stress.

[0047] The working principle of this embodiment is as follows: When using this welding device for processing hydraulic cylinder fittings, place the hydraulic cylinder to be welded on the first clamping plate 303. At this time, the first screw 305 rotates, driving the first slider 306 to move, and driving the second hydraulic pump 308 and the second clamping plate 309 to move through the first connecting rod 307. The second hydraulic pump 308 is started. When the outer surface of the second clamping plate 309 contacts the outer surface of the hydraulic cylinder and meets the above position requirements, the second hydraulic pump 308 continuously pushes the second clamping plate 309 to contact and clamp the surface of the hydraulic cylinder. At the same time, the first hydraulic pump 302 is started to push the first clamping plate 303 to move upward and push the hydraulic cylinder to move. When the hydraulic cylinder is concentric with the first annular internal gear disk 5, the first hydraulic pump 302 and the second hydraulic pump 308 stop operating. At this time, the first screw 305 drives the hydraulic cylinder to move inward. When the outer surface of the hydraulic cylinder is flush with the center, stop moving and keep the positions of the two hydraulic cylinders with the symmetrically arranged mechanism. At this time, the first gear motor 316 rotates, driving the cleaning component 3002 to rotate around the axis of the first annular internal gear disk 5. At the same time, the first spring 317 pulls the second sliding rod 311 to move downward, so that the friction plate 315 and the brush head 314 contact the outer surface of the hydraulic cylinder. At this time, driven by the first gear motor 316, the outer surface of the hydraulic cylinder is cleaned. The brush head 314 removes the impurities on the surface. While removing the impurities on the surface, the friction plate 315 roughens the surface of the hydraulic cylinder to make the welding tighter. At this time, welding is carried out.

[0048] Embodiment 2: Please refer to Figures 5 - 6 , on the basis of Embodiment 1, the present invention provides a technical solution: The slag removal and welding mechanism 6 includes a slot connection frame 601, and the slot connection frame 601 is rotatably connected to the inner surfaces of the first annular internal gear disk 5 and the second annular internal gear disk 7. A second gear motor 602 is fixedly connected inside the slot connection frame 601. A third sliding rod 603 is slidably inserted inside the slot connection frame 601. A second spring 604 is fixedly connected to the outer surface of the third sliding rod 603. A third arc-shaped column 612 is fixedly connected to the bottom of the third sliding rod 603. A welding head 611 is fixedly connected to the bottom of the third arc-shaped column 612. An electromagnet 606 is fixedly connected inside the slot connection frame 601. An arc-shaped slider 605 is slidably connected inside the slot connection frame 601. A fourth sliding rod 607 is slidably inserted inside the third arc-shaped column 612. A third spring 608 is fixedly connected to the outer surface of the fourth sliding rod 607. A steel brush head 609 is fixedly connected to the bottom of the fourth sliding rod 607. A triangular rubber column 610 is fixedly connected to the outer surface of the slot connection frame 601. The steel brush head 609 is used for removing slag from the welding surface of the hydraulic cylinder.

[0049] The outer surface of the arc-shaped slider 605 is in contact with the outer surface of the third sliding rod 603. The bottom of the second spring 604 is fixedly connected to the outer surface of the card slot connecting frame 601. The bottom of the third spring 608 is fixedly connected to the outer surface of the third arc-shaped column 612. The triangular rubber column 610 is slidably connected to the first annular internal gear disk 5 and the second annular internal gear disk 7. The triangular rubber column 610 is used to clean the inner surfaces of the first annular internal gear disk 5 and the second annular internal gear disk 7. By replacing the original electric push rod with the third sliding rod 603 and the second spring 604, while not changing the original performance, the adjustment of the welding head 611 is more sensitive and the welding head 611 is protected. The internal teeth of the triangular rubber column 610 and the first annular internal gear disk 5 and the second annular internal gear disk 7 are provided to reduce the influence of welding slag on their operation, and through the cleaning of the triangular rubber column 610, the operation effect is ensured to be good. The first gear motor 316 is related to the second gear motor 602 and moves simultaneously without interfering with each other.

[0050] The working principle of this embodiment is as follows: When using this welding device for processing hydraulic cylinder fittings, when the cleaning operation is completed and welding is required, the second gear motor 602 rotates, driving the slag removal and welding mechanism 6 to rotate around the axis of the first annular internal gear disk 5. At the same time, the second spring 604 pulls the third sliding rod 603 to move downward, driving the third arc-shaped column 612 to move downward, driving the welding head 611 to contact the surface of the hydraulic cylinder to be welded. At this time, the electromagnet 606 is activated, pushing the arc-shaped slider 605 to contact the outer surface of the third sliding rod 603, stopping the movement of the welding head 611. At the same time, the third spring 608 pulls the fourth sliding rod 607 to move downward, driving the steel brush head 609 to move downward and contact the outer surface of the hydraulic cylinder to be welded. At this time, driven by the second gear motor 602, the triangular rubber column 610 is pushed to clean and rotate on the inner surfaces of the first annular internal gear disk 5 and the second annular internal gear disk 7. After rotating one circle, the complete cleaning of the welding surface is achieved. At this time, the welding head 611 is activated to weld the welding surface. While welding, the front and rear steel brush heads 609 remove slag from the welding surface to ensure the stability of the welding quality.

[0051] Embodiment Three: Please refer to Figures 7 - 8, based on the first and second embodiments, the present invention provides a technical solution: The auxiliary cleaning mechanism 8 includes a fixed block 801, which is fixedly connected to the outer surface of the first annular internal gear disk 5. A second screw rod 802 is threadedly connected to the inside of the fixed block 801 through a threaded hole. A cross 803 is rotatably connected to the outer surface of the second screw rod 802. A third screw rod 804 is rotatably connected to the outer surface of the cross 803. A U-shaped frame 805 is threadedly connected to the outer surface of the third screw rod 804. A fourth arc-shaped column 806 is fixedly connected to the outer surface of the U-shaped frame 805. A V-shaped groove 807 is formed inside the fourth arc-shaped column 806. A first motor 808 is fixedly connected to the lower surface of the fourth arc-shaped column 806. An output end of the first motor 808 is fixedly connected to a cam 809. The fourth arc-shaped column 806 is used to clean the brush head 314 and the steel brush head 609.

[0052] The V-shaped groove 807 is in contact with the outer surface of the welding head 611. The distance between the second screw rod 802 and the symmetrically arranged second screw rod 802 is greater than the length of the fourth arc-shaped column 806. The outer surface of the U-shaped frame 805 is in contact with the outer surface of the cross 803. The cam 809 is used to vibrate the fourth arc-shaped column 806. The first motor 808 drives the vibration of the fourth arc-shaped column 806, so that the brush head 314 and the steel brush head 609 are cleaned by vibration. However, the wear of the friction plate 315 is relatively large, and the efficiency can only be maintained by replacement. A through hole is formed inside the second arc-shaped column 312 to provide a replacement channel. The operating distance of the third screw rod 804 is sufficient to move the entire U-shaped frame 805 out of the first annular internal gear disk 5, making its operation process stable and not affecting the welding.

[0053] The working principle of this embodiment is as follows: When using this welding device for processing hydraulic cylinder fittings, when it is necessary to clean the brush heads for impurity removal and slag removal after a welding operation, the second screw 802 rotates, driving the auxiliary cleaning mechanism 8 to move downward as a whole. When it moves to the end position, the movement stops. At this time, the third screw 804 rotates, driving the U-shaped frame 805 to move inward. When the outer surface of the U-shaped frame 805 comes into contact with the outer surface of the cross 803, the rotation stops. At this time, the V-shaped groove 807 is aligned with the welding head 611. Then, by continuing to rotate the second screw 802, the fourth arc-shaped column 806 is driven to move upward until the convex point position of the V-shaped groove 807 comes into contact with the outer surface of the welding head 611, at which point the rotation of the second screw 802 stops. At this time, the first motor 808 rotates, driving the cam 809 to rotate, vibrating the fourth arc-shaped column 806. At this time, driven by the first gear motor 316 and the second gear motor 602, the brush head 314 and the steel brush head 609 come into contact with the outer surface of the fourth arc-shaped column 806 through the first spring 317 and the third spring 608, and are cleaned by vibration to ensure the efficiency of impurity removal and slag removal. After the cleaning is completed, reverse its movement process to reset it without affecting the welding process.
