Description

Technical Field

[0001] This invention relates to the field of welding equipment, specifically to an automatic feeding and alignment welding device for angle brackets. Background Technology

[0002] Angle brackets are a type of metal bracket parts, mainly used for installing and supporting various parts. An angle is formed between the two ends of the angle bracket, and one end of the angle bracket is provided with a socket hole in which a plug plate is pre-inserted. During the processing, the connection between the angle bracket and the plug plate needs to be spot welded.

[0003] Currently, although the welding of angle brackets and insert plates can be automatically spot welded by spot welding machines, angle brackets with pre-installed insert plates need to be manually loaded into the carrier at the spot welding machine for positioning and clamping before spot welding can be performed. Existing equipment cannot achieve automatic alignment, automatic reversal, and automated clamping of angle brackets. If a high-degree-of-freedom robot is used, the cost is high. Therefore, an automatic loading, alignment, and spot welding device for angle brackets is needed. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic feeding and alignment welding device for angle brackets, thereby solving the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic feeding and alignment welding device for angle brackets, comprising a base, on which a rotary positioning component is provided, the rotary positioning component comprising a transverse moving device, a guide seat rotatably connected to the base, a turntable rotatably connected to the moving platform of the transverse moving device, and a guide rod slidably connected to the guide seat, the guide rod being fixedly connected to the turntable, a seat plate being fixedly connected to the turntable, a positioning seat being hinged to the seat plate, a torsion spring being provided at the connection between the positioning seat and the seat plate, an alignment slope plate being provided on the base next to the positioning seat, a clamping component being provided at the included angle at both ends of the positioning seat, and a spot welding machine and an auxiliary alignment component being provided on the base next to the rotary positioning component.

[0006] Furthermore, the lateral movement device is specifically a rodless cylinder, and the lateral movement device is fixedly connected to the base.

[0007] Furthermore, a pulley is rotatably connected to the lower part of the positioning seat, and an arc-shaped surface is provided on the side of the alignment slope plate near the positioning seat, with the pulley being tangent to the arc-shaped surface of the alignment slope plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: through multiple linkage structures, it is possible to realize automated alignment, automated material reversal, automated clamping and spot welding of the angled bracket, without the need for a high degree of freedom robotic arm, resulting in lower cost and improved production efficiency of the angled bracket.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example:

[0021] Please see Figure 1-6 An automatic feeding and alignment welding device for angle brackets includes a base 1. A rotary positioning component is provided on the base 1. The rotary positioning component includes a lateral moving device 201, a guide seat 202 rotatably connected to the base 1, a turntable 203 rotatably connected to the moving platform of the lateral moving device 201, and a guide rod 204 slidably connected to the guide seat 202. The guide rod 204 is fixedly connected to the turntable 203. A seat plate 3 is fixedly connected to the turntable 203. A positioning seat 301 is hinged to the seat plate 3. A torsion spring is provided at the connection between the positioning seat 301 and the seat plate 3. An alignment slope plate 4 is provided on the base 1 next to the positioning seat 301. A clamping component 5 is provided at the included angle at both ends of the positioning seat 301. A spot welding machine 6 and an auxiliary alignment component 7 are provided on the base 1 next to the rotary positioning component.

[0022] The lateral movement device 201 is specifically a rodless cylinder, which drives the turntable 203 to perform translational movement. A pulley 302 is rotatably connected to the lower part of the positioning seat 301. An arc-shaped surface is provided on the side of the alignment slope plate 4 near the positioning seat 301. During the reversing feeding action, during the translation of the seat plate 3, under the action of the guide seat 202 and the guide rod 204, the turntable 203 and the seat plate 3 will perform rotational reversal action, and the pulley 302 will be tangent to the arc-shaped surface of the alignment slope plate 4.

[0023] A positioning groove is provided on the positioning seat 301. The positioning groove is used to position the loading angle bracket 8. The clamping assembly 5 includes a cylinder seat 501, a limiting cylinder 502 and an angle limiting rod 503. The extension and retraction of the piston rod of the limiting cylinder 502 is used to drive the angle limiting rod 503 to translate. The end of the angle limiting rod 503 is provided with a tapered surface, which can better limit the angle bracket 8. The extension and retraction of the piston rod of the limiting cylinder 502 is used to drive the angle limiting rod 503 to perform the limiting action.

[0024] The auxiliary alignment component 7 includes a lifting cylinder 701, a slanted stop 702, an alignment top plate 703, a spring 704, and a guide frame 705. The guide frame 705 guides the sliding of the alignment top plate 703. A roller 706 is rotatably connected to the side of the alignment top plate 703. During the clamping action, the extension and retraction of the piston rod of the lifting cylinder 701 drives the alignment top plate 703 to rise. During the rising process, when the roller 706 contacts the inclined surface of the slanted stop 702, the slanted stop 702 pushes the roller 706 and the alignment top plate 703 closer to the insertion plate 9, pressing the insertion plate 9 against the angle bracket 8 to complete the alignment clamping. When releasing the clamp, the spring 704 can reset the alignment top plate 703.

[0025] The working principle of this invention is as follows: When using this invention, firstly, the angle bracket 8 is loaded (one end of the angle bracket 8 has an insertion hole, into which an insertion plate 9 is pre-inserted). The lateral moving device 201 drives the seat plate 3 to slide towards the alignment slope plate 4. During this sliding process, under the action of the guide seat 202 and the guide rod 204, the turntable 203 and the seat plate 3 will rotate and change direction. When the pulley 302 at the bottom of the seat plate 3 contacts the arc-shaped surface of the alignment slope plate 4, the positioning seat 301 will flip upward relative to the seat plate 3 and tilt. At this time, the angle bracket 8 to be processed is placed along the positioning seat 301. Since the positioning seat 301 is tilted at this time, the angle bracket 8 will automatically be initially aligned under the action of gravity when placed. After alignment is completed, the piston rod of the limiting cylinder 502 extends, and the angle limiting rod 503 slides and is tangential to both ends of the angle bracket 8 to achieve limiting. Afterwards, the lateral moving device 201 resets, and the angle bracket 8 will move horizontally and rotate simultaneously. (See reference...) Figure 5 and Figure 6 Until the angle bracket 8 is located at the welding station, before welding the angle bracket 8, the piston rod of the lifting cylinder 701 drives the alignment top plate 703 to rise. During the rising process, when the roller 706 contacts the inclined surface of the inclined block 702, the inclined block 702 pushes the roller 706 and the alignment top plate 703 closer to the insert plate 9, pressing the insert plate 9 tightly against the angle bracket 8 to complete the alignment clamping. Finally, the welding gun of the spot welding machine 6 performs spot welding on the connection between the insert plate 9 and the angle bracket 8 from above.
