Description

Technical Field

[0001] This invention relates to the field of fully automatic welding machine technology, specifically to a fully automatic welding machine. Background Technology

[0002] A fully automatic welding machine is a highly automated machine primarily used for welding metal sheets or parts to obtain corresponding metal products. When welding metal sheets that have been rolled into circles (resulting in a circular shape), an automatic welding machine is needed to improve processing efficiency.

[0003] Chinese patent application CN110328473A discloses a circular shell welding device, comprising a cylinder, a welding machine, a slider, a welding head, a rotary welding module, a worktable, and a base. The base is connected to the lower end of the welding machine, the worktable is connected to the middle of the side of the welding machine, the rotary welding module is connected to the worktable, the cylinder is connected to the upper end of the welding machine, the cylinder is connected to the slider, and the slider is connected to the welding head. The rotary welding module includes a servo motor, a mandrel, a guide block, and a fixed cylinder. The servo motor passes through the guide block and is connected to the mandrel. The fixed cylinder is located at the bottom of the guide block and is connected to the guide block. This invention realizes an automated welding process for circular shells, eliminating the need for manual operation, greatly improving production efficiency, and achieving good welding results with a low product scrap rate, thus saving costs for enterprises.

[0004] However, this automatic welding machine has the following drawbacks in practical use:

[0005] 1. Existing automatic welding machines, when welding metal sheets into a circle, typically only weld one sheet at a time. Furthermore, after each welding operation, the finished product needs to be disassembled before the next set of sheets to be welded can be installed, resulting in low overall welding efficiency. Additionally, the welded areas are prone to fatigue fracture during disassembly, leading to cracks and low-quality finished products.

[0006] 2. Existing automatic welding machines require clamping and fixing the metal sheets to ensure stability during welding and prevent weld seam displacement due to vibration. However, clamping and fixing the metal sheets can cause the welding points to be obstructed, affecting the continuity of the welding operation. Separate welding operations can result in different temperatures at the starting points of the welds and can easily lead to weld overlap, affecting the quality of the welded metal product.

A welding gun is mounted on the bottom of the deflection block by screws.

[0048] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0049] 1. In a fully automatic welding machine, when the welded metal product is moved in a circular motion to remove it from the bottom of the welding gun, and another metal plate to be welded is moved to the bottom of the welding gun, the force of the rotating intermediate gear synchronously drives the cooling fan blades to rotate. This automatically cools the welded metal product, ensuring that the weld points do not crack due to insufficient cooling during disassembly, thus guaranteeing the strength and quality of the welded metal product. Simultaneously, the cooling fan blades, which drive the metal product for cooling and positioning, are driven by two gears of different sizes. The larger gear drives the smaller gear, allowing the cooling fan blades to rotate 360 ​​degrees multiple times, improving the cooling and shaping effect on the metal product (after welding) at the bottom of the cooling fan blades.

[0050] 2. In fully automatic welding machines, when welding metal sheets, the rotating clamping arms hold the metal sheets inside, ensuring that the sheets do not wobble or shift during welding, and preventing mis-welding. Simultaneously, the clamping arms can bend the metal sheets, ensuring that the edges (welding points) are close together, allowing for direct welding to complete the entire operation. Furthermore, during actual welding, the extension arm at the top of the welding point can rotate to clear the area for subsequent welding, ensuring the quality of the finished metal product.

[0051] 3. In fully automatic welding machines, when welding clamped and fixed metal plates, the welding torch can move vertically up and down and horizontally to extend and retract, facilitating the movement of the welding torch towards the welding point on the metal plate and achieving automated welding operations (direct welding). Simultaneously, when disassembling a welded and cooled metal product to install another set of metal plates to be welded, the disassembly and installation of the metal plates and the product can be performed concurrently with the welding operation, maximizing the efficiency of metal plate welding.

[0052] 4. In fully automatic welding machines, when welding metal sheets (direct welding), the welding torch is rotated by a deflection motor that drives gears. This allows for adjustment of the laser beam direction emitted by the torch, extending the welding length and accommodating welding operations on metal sheets of different sizes and specifications. Simultaneously, the welding torch can be raised and lowered while rotating, ensuring it remains close to the welding point on the metal sheet and guaranteeing optimal welding results.

[0076] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0077] Please see Figures 1-12The fully automatic welding machine includes a chassis 10, a cross-shaped operating table 20, an integrated circulating clamping mechanism 30, and an automatic welding mechanism 40. The cross-shaped operating table 20 is mounted on the top of the chassis 10, and the integrated circulating clamping mechanism 30 is mounted on top of the cross-shaped operating table 20. Multiple metal plates are clamped and fixed inside the integrated circulating clamping mechanism 30. The automatic welding mechanism 40 is located on the side of the integrated circulating clamping mechanism 30, extending above the metal plates and performing automatic welding on them. The integrated circulating clamping mechanism 30 includes a gear circulation assembly 50, a ring clamping assembly 60, and a speed-changing cooling assembly 70. The gear circulation assembly 50 is mounted on the cross-shaped operating table 20. On the top of the worktable 20, multiple annular clamping assemblies 60 are installed on the top of the gear circulation assembly 50. Metal plates are clamped and fixed on the inner side of the annular clamping assemblies 60. A speed-changing cooling assembly 70 is meshed and connected to the side of the gear circulation assembly 50. The speed-changing cooling assembly 70 is installed on the top of the cross worktable 20, which extends above the annular clamping assemblies 60. The automatic welding mechanism 40 includes a vertical lifting assembly 80, a welding adjustment assembly 90, and a welding gun 100. The vertical lifting assembly 80 is installed on the top of the cross worktable 20 by screws. The vertical lifting assembly 80 is located on the side of the gear circulation assembly 50. The welding adjustment assembly 90 is installed on the side of the vertical lifting assembly 80, and the welding gun 100 is installed on the side of the welding adjustment assembly 90.

[0078] In this invention, the included angle of the chassis 10 is recessed inward, and an L-shaped reinforcing frame 101 is installed in the recessed part of the chassis 10. A cross-shaped operating table 20 is installed on the side of the L-shaped reinforcing frame 101 by screws. An operating position 201 is provided at the top edge of the cross-shaped operating table 20, and the operating position 201 is located on the side of the gear circulation assembly 50.

[0079] The working principle is as follows: When welding metal sheets into a circular metal product, the rolled metal sheet is placed inside the annular clamping assembly 60, which clamps and fixes the metal sheet, bringing the welding points of the metal sheet closer together. Then, the gear circulation assembly 50 operates, moving the metal sheet to be welded below the welding gun 100, where the welding gun 100 automatically completes the welding operation. Simultaneously, after welding, the gear circulation assembly 50 moves the welded metal product below the variable speed cooling assembly 70, which automatically and rapidly cools the metal product, reducing the risk of cracks and improving the quality of the welded product. It also moves the cooled metal product to the side of the operator (towards the operating position 201), facilitating disassembly and assembly of the next metal sheet, thus improving the efficiency of metal sheet processing.

[0080] In this invention, the vertical lifting component 80 and the welding adjustment component 90 can drive the welding gun 100 to move up, down and rotate, thereby realizing automated welding operations.

[0081] For details, please refer to the following: Figure 5 and Figure 6 The gear circulation assembly 50 includes an intermediate gear 501, which is rotatably connected to the center of the top of the cross-shaped operating table 20. A main gear 502 is meshed with one side of the intermediate gear 501 and is rotatably connected to the eccentric part of the top of the cross-shaped operating table 20. A main shaft 503 is connected to the top of the main gear 502 and is connected to the output end of a drive motor 504. The drive motor 504 is mounted on the top of a base 505, which is mounted on the eccentric part of the top of the cross-shaped operating table 20 by screws. A disc 506 is mounted on the top of the intermediate gear 501.

[0082] In this embodiment, a speed-changing cooling assembly 70 is meshed with the side of the intermediate gear 501. The speed-changing cooling assembly 70 is disposed on the side of the main gear 502. A plurality of annular clamping assemblies 60 are installed at the top eccentric part of the disc 506 by screws.

[0083] In the fully automatic welding machine of the present invention, when it is necessary to rotate and feed metal plates and metal products, the drive motor 504 is started to operate, driving the main shaft 503 connected to its output end to rotate. When the main shaft 503 rotates, the main gear 502 connected to its bottom can rotate, causing the intermediate gear 501 meshing with the side of the main gear 502 to rotate, and driving the disc 506 connected to the top of the intermediate gear 501 to rotate.

[0084] For details, please refer to the following: Figure 5 and Figure 7 The annular clamping assembly 60 includes a lower support base 601, which is mounted on the top eccentric position of the disc 506 by screws. A first linear motor 602 is mounted on one side of the lower support base 601, and the output end of the first linear motor 602 is connected to a rotating shaft 603.

A movable block 604 is mounted on the outside of the rotating shaft 603 and is movably disposed inside the grooves 6011. A clamping arm 605 is mounted on the top of the movable block 604 by screws. The clamping arm 605 is movably disposed on the top of the lower support base 601. A metal plate is clamped and fixed on the inner side of the clamping arm 605.

[0085] In this embodiment, the top of the clamping arm 605 is recessed inward, and the recessed part of the clamping arm 605 is movably connected to the extension arm 6051. The extension arm 6051 is arc-shaped, and a metal plate is clamped and fixed on the inner side of the extension arm 6051. The extension arm 6051 is connected to the output end of the second linear motor 6052, and the second linear motor 6052 is installed on the side of the clamping arm 605.

[0086] In the above embodiments, when welding is required on the clamped metal plate, the second linear motor 6052 operates, driving the extension arm 6051 connected to the output end of the second linear motor 6052 to rotate, opening one side of the welding point of the metal plate, ensuring that the welding can be completed in one go when the metal plate is welded by the welding gun 100, and without affecting the stability of the metal plate during the welding operation.

[0087] In the fully automatic welding machine of the present invention, when clamping and fixing the metal plates and bringing the welding points of the metal plates closer together, the metal plates are placed on top of the lower support 601, and the first linear motor 602 is started to operate, driving the rotating shaft 603 connected to the output end of the first linear motor 602 to rotate. At this time, when the rotating shaft 603 rotates, the movable block 604 installed on its outer side will drive the clamping arm 605 to rotate, clamping, fixing and pressing the metal plates set at the bottom of the clamping arm 605, ensuring that the welding points of the metal plates can be brought close together.

[0088] For details, please refer to the following: Figure 6 , Figure 8 and Figure 9The transmission cooling assembly 70 includes a driven gear 701, which is meshed with the other side of the intermediate gear 501.

A main transmission gear 704 is connected to the vertical shaft 702. A drive gear 705 is rotatably connected to the top of the connecting frame 703. The main gear 704 is meshed with the side of the drive gear 705, which is rotatably connected to the top of the connecting frame 703. A connecting rod 706 is mounted on the top of the drive gear 705 and passes through the bottom seat 707, which is mounted on the top of the connecting frame 703. A drive belt 708 is connected to the outer side of the top of the connecting rod 706 via a keyed synchronous pulley. The drive belt 708 is movably mounted on the top of the bottom seat 707.

[0089] In this embodiment, a movable rod 7081 is connected to the inner side of the transmission belt 708 via a synchronous pulley key.

A cooling fan blade 7082 is installed at the bottom of the movable rod 7081 and is movably located at the bottom of the connecting frame 703.

[0090] In the above embodiment, when the transmission belt 708 is running, the movable rod 7081 connected to its inner side by the synchronous pulley key will rotate, causing the cooling fan blades 7082 installed at the bottom of the movable rod 7081 to rotate, thereby cooling the metal product after welding.

[0091] In the fully automatic welding machine of the present invention, when the intermediate gear 501 rotates, the driven gear 701, which is meshed with its side, rotates, driving the vertical shaft 702 connected to the top of the driven gear 701 to rotate. At this time, the rotation of the vertical shaft 702 drives the main transmission gear 704 connected to its top to rotate, causing the driven transmission gear 705, which is meshed with the side of the main transmission gear 704, to rotate. When the driven transmission gear 705 rotates, the connecting rod 706 connected to its top rotates, causing the synchronous pulley and the transmission belt 708 keyed to the connecting rod 706 to operate.

[0092] For details, please refer to the following: Figure 10The vertical lifting assembly 80 includes two vertical frames 801, both of which are mounted on the top of the cross-shaped operating table 20 by screws. A servo motor 802 is mounted on the top of one vertical frame 801.

[0093] In the fully automatic welding machine of this invention, when welding the clamped metal plate, the servo motor 802 is automatically started, driving the reciprocating lead screw 803 connected to the output end of the servo motor 802 to rotate. As the reciprocating lead screw 803 rotates, the lifting slide 804 connected to it via ball bearings moves up and down, driving the horizontal beam 805 mounted on the side of the lifting slide 804 to move up and down as well. The vertical slider 806 mounted on the other side of the horizontal beam 805 can slide on the outside of the vertical guide rod 807, ensuring the stability of the horizontal beam 805 during its lifting movement.

Between the movable bodies 903, a deflection motor 905 is mounted on the back of the mounting base 904. The output end of the deflection motor 905 is connected to a rotating gear 906. There are two rotating gears 906, which are meshed and connected to the inner wall of the mounting base 904. The shaft end of the other rotating gear 906 is connected to a deflection block 907. The deflection block 907 is movably disposed inside the mounting base 904. A welding gun 100 is mounted on the bottom of the deflection block 907 by screws.

[0095] In the fully automatic welding machine of this invention, when welding the clamped metal sheet, the telescopic cylinder 9031 operates, driving the movable body 903 connected to the output end of the telescopic cylinder 9031 to move horizontally. This allows the mounting base 904 and welding gun 100 mounted on the side of the movable body 903 to move horizontally, realizing direct welding of the metal sheet. Simultaneously, during actual welding, the deflection motor 905 operates and drives the rotating gear 906 to rotate. This causes the rotating gear 906, which is meshed on the side of the rotating gear 906, to rotate. This, in turn, causes the deflection block 907, coaxially connected to another rotating gear 906, to drive the welding gun 100 to rotate, achieving a wider range of metal sheet welding operations.

[0096] Therefore, any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this invention, based on the technical solution and inventive concept of this invention, should be covered within the protection scope of this invention.
