Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts welding, in particular to an automatic electric welding device for automobile parts. Background Art

[0002] Automatic welding equipment for automotive parts typically utilizes advanced automation technologies and welding processes, utilizing precise control systems to achieve efficient and accurate welding of automotive parts. First, the automotive part to be welded must be accurately placed on the welding equipment's workbench and secured with a clamping device to prevent movement during the welding process.

[0003] During welding, defects can occur due to improper weld groove angles, uneven assembly gaps, inadequate weld cleaning, excessive or insufficient welding current, excessive or slow welding speeds, excessive or insufficient electrode (gun) swing, and improper welding angle selection. At this time, the clamping device holds the workpiece in place, leaving inspectors with insufficient space to move and operate inspection tools such as ultrasonic flaw detectors and magnetic particle detectors. These tools typically require sufficient operating space to ensure accurate and effective inspection. This necessitates removing the workpiece to inspect the weld or walking around it. Careless disassembly, especially for workpieces requiring high precision, can damage the welded portion, resulting in the workpiece being scrapped. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic electric welding device for automobile parts to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0009] A groove is provided on the rotating plate, and a protrusion is provided in the groove.

[0010] Preferably, the welding assembly includes a robotic arm and a welding gun, the robotic arm is mounted on a support plate, the welding gun is arranged at an end of the robotic arm away from the support plate, a slide groove is provided on the mounting seat, a slider is symmetrically slidably connected in the slide groove, and two groups of limit blocks are symmetrically arranged on the slider.

[0011] Preferably, the outer edge of the rotating plate is slidably connected to the slider via a limit block on the slider, the two sliders are connected via a connecting rod, and mounting holes are provided on the sliders.

[0012] Preferably, the inner walls of the mounting holes are slidably connected to the outer surface of the sliding rod, and the sliding rod is provided with a plurality of teeth.

[0013] Preferably, the sliders are all provided with fixing rods, and the fixing rods are all rotatably connected with rotating shafts.

[0014] Preferably, the rotating shaft is externally connected to an external drive, and both ends of the rotating shaft are fixedly connected to gears.

[0015] Preferably, the gear is engaged with a plurality of teeth provided on the slide rod.

[0016] Preferably, an elastic member is provided at the bottom of the groove, and the elastic member is adapted to the diameter of the groove and is fixedly connected to the bottom of the groove.

[0017] Preferably, one end of the elastic member away from the bottom of the groove is fixedly connected to the protrusion.

[0018] Preferably, the outer surface of the protrusion slides on the inner wall of the groove, and one side of the protrusion is set as an inclined surface and the other side is set as a horizontal surface.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The sliding rod connected by sliding enables the support plate above it to be adjusted to different heights to adapt to the needs of the robotic arm during the welding process. The slide rod with adjustable height enables the support plate above the mounting rod to move horizontally up and down, so that the welding components move synchronously, avoiding the welding components blocking the field of view when the welding results need to be checked.

[0021] By rotating the rotating plate clockwise during welding, the inclined surface of the protrusion will be squeezed by the slider, thereby compressing the elastic part and squeezing the protrusion into the groove. At this time, the position of the slider remains fixed relative to the rotating plate, so that the welding assembly above the support plate can weld the automotive parts on the four-claw disk. When it is necessary to check the welding results, rotate the rotating plate counterclockwise, and the horizontal surface of the protrusion will fit with the slider, and drive the slider to rotate synchronously with the rotating plate in the slide groove. When a defective weld is found, stop rotating the rotating plate and push the slider to the defective weld for re-welding. This design allows for easy release of the fixation after welding is completed for inspection or repositioning without disassembling the entire tooling or repositioning the automotive parts, thereby saving time and cost.

[0028] The present invention is described in further detail below with reference to the accompanying drawings.

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0030] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positions are based on the directions or positional relationships shown in the accompanying drawings, which are merely simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.

[0031] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example

[0032] See also Figure 1-Figure 4 , an automatic electric welding equipment for automobile parts, comprising: a mounting base 1, a slide bar 8 and a groove 14, the mounting base 1 is mounted on the workbench by fastening screws, the mounting base 1 is rotatably connected to a connecting shaft 2, and the connecting shaft 2 is fixedly connected to a rotating plate 3, and a four-claw disk 4 is provided on the rotating plate 3. The installation of the connecting shaft 2 causes the rotating plate 3 to rotate on the mounting base 1, thereby causing the workpiece to be mounted on the four-claw disk 4 to rotate synchronously, wherein the four-claw disk 4 is externally driven to cause the four claws to gather at the center to clamp the workpiece; the slide bars 8 are all arranged above the mounting base 1, and the slide bars 8 are all fixedly connected to the mounting rods 9, and a support plate 10 is provided on the mounting rod 9, and a welding assembly is arranged above the support plate 10, and the height-adjustable slide bar 8 causes the support plate 10 above the mounting rod 9 to move horizontally up and down, thereby causing the welding assembly to move synchronously, avoiding the welding assembly blocking the field of view when the welding result needs to be checked.

[0033] The welding assembly includes a robot arm 1001 and a welding gun 1002. The robot arm 1001 is mounted on a support plate 10, and the welding gun 1002 is located at an end of the robot arm 1001 away from the support plate 10. The robot arm 1001 can move with extremely high precision to ensure that the welding gun 1002 accurately reaches the predetermined welding position. The mounting base 1 is provided with a chute 5, and a slider 6 is symmetrically slidably connected in the chute 5. The slider 6 is symmetrically provided with two sets of limit blocks. The chute 5 is set in an arc shape and is concentric with the rotating plate 3 to ensure that the slider 6 can slide synchronously while the rotating plate 3 rotates. The outer edge of the rotating plate 3 is slidably connected to the slider 6 through the limit blocks on the slider 6. The limit blocks and the outer edge of the rotating plate 3 are in contact with each other. When the slider 6 is required to rotate synchronously with the rotating plate 3, the limit plates and the rotating plate 3 are relatively fixed. When the slider 6 is not required to rotate synchronously with the rotating plate 3, the rotating plate 3 slides between the limit blocks. The resistance of the chute 5 to the slider 6 is greater than the elastic force of the elastic member 15.

[0034] Furthermore, the two sliders 6 are connected by a connecting rod. The two sliders 6 ensure that the lifting force on the support plate 10 is evenly distributed, which helps to reduce the stress concentration problem caused by excessive force on a single point and reduce the risk of component damage; the sliders 6 are each provided with a mounting hole 7, and the inner wall of the mounting hole 7 is slidably connected to the outer surface of the slide rod 8. The slidingly connected slide rod 8 enables the support plate 10 above it to be adjusted to different heights to meet the needs of the welding process of the robot arm 1001.

[0035] It should be noted that each slide bar 8 is equipped with a plurality of teeth. Each slider 6 is provided with a fixed rod 11, which is rotatably connected to a rotating shaft 12. The rotating shaft 12 is externally connected to an external drive, and gears 13 are fixedly connected to each end of the rotating shaft 12. The gears 13 mesh with the teeth on the slide bar 8. By activating the external drive, the gears 13 continuously rotate, which in turn drives the slide bar 8 up and down through the meshing teeth on the slide bar 8. The provision of the gears 13 further enhances the precision of the adjustment.

[0036] Furthermore, a groove 14 is formed on the rotating plate 3, a protrusion 16 is provided in the groove 14, and an elastic member 15 is provided at the bottom of the groove 14. The elastic member 15 is adapted to the diameter of the groove 14 and is fixedly connected to the bottom of the groove 14. The end of the elastic member 15 away from the bottom of the groove 14 is fixedly connected to the protrusion 16. The outer surface of the protrusion 16 slides on the inner wall of the groove 14, and one side of the protrusion 16 is set as an inclined surface and the other side is set as a horizontal surface. When welding is required, the rotating plate 3 is rotated clockwise, and the inclined surface of the protrusion 16 will be squeezed by the slider 6, thereby compressing the elastic member 15 and squeezing the protrusion 16 into the groove 14. At this time, the position of the slider 6 remains fixed relative to the rotating plate 3, so that the welding assembly above the support plate 10 welds the automotive parts on the four-claw disk 4. When it is necessary to check the welding results, the rotating plate 3 is rotated counterclockwise, and the horizontal surface of the protrusion 16 will fit with the slider 6, and drive the slider 6 to rotate synchronously with the rotating plate 3 in the slide groove 5. When a defective weld is found, the rotating plate 3 is stopped and the slider 6 is pushed to the poor welding part for re-welding. This design allows for easy release of the fixation after welding is completed for inspection or repositioning without disassembling the entire tooling or repositioning the automotive parts, thereby saving time and cost.
