[0001] This utility model relates to the technical field of welding fixtures, and in particular to a welding fixture for processing automotive parts. Background Technology

[0002] Welding of automotive parts is a method of joining two separate metal objects of the same or different types into one piece through appropriate means in automobile manufacturing. When welding automotive parts, fixtures are needed to limit and fix the parts.

[0003] A welding fixture for automotive parts, disclosed on the Chinese Patent Network (publication number CN212761912U), relates to the field of welding fixtures. The fixture body has a mounting frame installed on its top. A sliding block is connected to the outer surface of the mounting frame, and a moving rod is connected to the back of the sliding block. Sliding sleeves are connected to both sides of the moving rod. This utility model provides a welding fixture for automotive parts, comprising a moving rod, a fixed block, a sleeve, a fixed rod, and a through hole. When the operating block needs to be moved, the movement of the sliding blocks at both ends of the moving rod on the mounting frame is adjusted to a suitable position. The sliding sleeve is moved on the moving rod to the approximate area. The second screw is rotated, causing the sleeve connected to the second screw to move. The sliders on both sides of the sleeve move in the sliding grooves on both sides of the fixed block, causing the sleeve to be pressed downwards, fixing the fixed rod inside the through hole in the fixture body, thus fixing the fixed block and achieving the effect of quickly adjusting different directions.

[0004] The solution also has the following problems: the fixture is not equipped with eye protection when in use, the strong light generated by welding can damage the eyes of the workers, and the operation is cumbersome and inconvenient when clamping parts, which reduces the processing efficiency. Therefore, it has certain drawbacks.

[0005] Therefore, in order to solve the above problems, this utility model provides a welding fixture for processing automotive parts. Summary of the Invention

[0006] The purpose of this invention is to provide a welding fixture for processing automotive parts, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a welding fixture for processing automotive parts, comprising a base, wherein several sets of support columns are arranged in a circular array along the top edge of the base, and an operating platform is mounted on the top of the support columns. Four sets of sliding grooves are arranged in a circular array on the top of the operating platform, with sliding rods installed inside the grooves. A slider is mounted on the outer ring surface of the sliding rod, and a limit clamp is mounted on the top of the slider. A support seat is mounted at one edge of the top of the operating platform, and an electric telescopic rod is mounted on the top of the support seat. A support plate is mounted on the movable end of the top of the electric telescopic rod, and semicircular blocks are symmetrically mounted at both ends of the top of the support plate. A safety guard is mounted on the top of the support plate, located between two semicircular blocks.

[0008] Preferably, a servo motor is installed at the top center of the base, and a rotating disk is installed on the output shaft of the servo motor. The top of the rotating disk has four sets of arc-shaped grooves arranged in a ring, and the top of the rotating disk is in contact with the bottom of the operating table.

[0009] Preferably, the outer ring surface of the slide rod is slidably connected to the inside of the slider, and a fixing post is installed at the bottom of the slider and inside the arc groove.

[0010] Preferably, the bottom of the goggle panel is rotatably connected to the top of the support plate, and the goggle panel is provided with goggle lenses to reduce arc light and filter infrared and ultraviolet rays. Furthermore, the support plate does not contact the limiting clamp when it is raised and lowered with the electric telescopic rod.

[0011] Preferably, threaded rods are installed at both ends of the outer side of the goggle and inside the two semicircular grooves, and threaded caps are installed on the outer side of the threaded rods and in close contact with the semicircular blocks.

[0012] Preferably, the limiting clamp is equipped with an anti-slip pad on its exterior.

[0013] In summary, this utility model has the following beneficial technical effects: This welding fixture for processing automotive parts features an arc-shaped groove that pushes a fixed column to move when the rotating disk is driven by a servo motor. Since the fixed column is installed at the bottom of the slider, and the slider is slidably connected to the slide rod, the movement of the fixed column causes the slider to slide on the slide rod, thereby moving the limiting clamp. This allows for clamping or releasing the automotive parts. The protective eye plate is rotatably connected to the support plate, allowing operators to adjust its tilt angle according to the welding position and angle for optimal protection. After adjusting the protective eye plate to the appropriate angle, tightening the threaded cap causes it to move on the threaded rod and fit tightly against the semi-circular block, thus fixing the protective eye plate at the current angle. This ensures stable protection during welding, making the operation convenient and practical. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1 - Figure 4 The present invention will be described in further detail below.

[0017] A welding fixture for machining automotive parts, as shown in the reference. Figure 1 - Figure 4 The system includes a base 1, with several sets of support columns 2 arranged in a ring at the top edge of the base 1. An operating platform 3 is installed on the top of the support columns 2. Four sets of sliding grooves 301 are arranged in a ring at the top of the operating platform 3. Sliding rods 4 are installed inside the sliding grooves 301. Sliding blocks 5 are installed on the outer ring surface of the sliding rods 4. Limiting clamps 6 are installed on the top of the sliding blocks 5. A support seat 7 is installed at one edge of the top of the operating platform 3. An electric telescopic rod 8 is installed on the top of the support seat 7. A support plate 9 is installed on the movable end of the top of the electric telescopic rod 8. Semicircular blocks 10 are symmetrically installed at both ends of the top of the support plate 9. A safety guard 11 is installed on the top of the support plate 9 and between the two semicircular blocks 10.

[0018] Reference Figure 1 - Figure 3A servo motor 12 is installed at the top center of the base 1. A rotating disk 13 is mounted on the output shaft of the servo motor 12. The top of the rotating disk 13 has four sets of arc-shaped grooves 1301 arranged in a circular array. The top of the rotating disk 13 is in contact with the bottom of the operating table 3. When the servo motor 12 is working, its output shaft drives the rotating disk 13 to rotate. Because the top of the rotating disk 13 is in contact with the bottom of the operating table 3, the rotating disk 13 can rotate stably at the bottom of the operating table 3. The arc-shaped grooves 1301 on the rotating disk 13 are for subsequent connection with the bottom fixing post 14 of the slider 5. In accordance with the conditions provided for the movement, the outer ring surface of the slide rod 4 is slidably connected to the inside of the slider 5. The bottom of the slider 5 and inside the arc groove 1301 are both equipped with fixed posts 14. When the rotating disk 13 is driven by the servo motor 12 to rotate, the arc groove 1301 will push the fixed posts 14 to move. Since the fixed posts 14 are installed at the bottom of the slider 5 and the slider 5 is slidably connected to the slide rod 4, the movement of the fixed posts 14 will drive the slider 5 to slide on the slide rod 4, thereby realizing the movement of the limit clamp 6 and realizing the clamping or loosening action of the car parts.

[0019] Reference Figure 1 - Figure 4 The bottom of the protective goggle 11 is rotatably connected to the top of the support plate 9. The protective goggle 11 contains a lens that reduces arc light and filters infrared and ultraviolet rays. The support plate 9 does not contact the limiting clamp 6 when it rises and falls with the electric telescopic rod 8. The rotatable connection between the protective goggle 11 and the support plate 9 allows operators to adjust the tilt angle of the protective goggle 11 according to the welding position and angle to achieve optimal protection. The lens inside the protective goggle 11 effectively reduces arc light generated during welding and filters infrared and ultraviolet rays, protecting the operator's eyes. The support plate 9 does not contact the limiting clamp 6 when it rises and falls with the electric telescopic rod 8, avoiding... This eliminates interference between the two and ensures the normal operation of the fixture. Threaded rods 15 are installed at both ends of the outer side of the protective plate 11 and inside the two semicircular grooves 1001. Threaded caps 16 are installed on the outer side of the threaded rods 15 and in close contact with the semicircular block 10. When the angle of the protective plate 11 needs to be adjusted, the threaded caps 16 can be loosened first, allowing the protective plate 11 to rotate around its rotational connection point with the support plate 9. After adjusting to the appropriate angle, the threaded caps 16 are tightened. The threaded caps 16 move on the threaded rods 15 and fit tightly against the semicircular block 10, thereby fixing the protective plate 11 at the current angle and ensuring that the protective plate 11 can stably provide protection during the welding process.

[0020] Reference Figure 1 - Figure 2 The limiting clamp 6 is equipped with an anti-slip pad 17. When the limiting clamp 6 clamps and fixes the car parts, the anti-slip pad 17 can increase the friction between the limiting clamp 6 and the car parts, prevent the car parts from sliding or shifting during the welding process, ensure the accuracy and stability of the welding, and improve the welding quality.

[0021] The implementation principle of a welding fixture for processing automotive parts according to this utility model embodiment is as follows: When the fixture is used, the output shaft of the servo motor 12 drives the rotating disk 13 to rotate. Since the top of the rotating disk 13 is in contact with the bottom of the operating table 3, the rotating disk 13 can rotate stably at the bottom of the operating table 3. When the rotating disk 13 rotates under the drive of the servo motor 12, the arc groove 1301 will push the fixed column 14 to move. Since the fixed column 14 is installed at the bottom of the slider 5 and the slider 5 is slidably connected to the slide rod 4, the movement of the fixed column 14 will drive the slider 5 to slide on the slide rod 4, thereby realizing the movement of the limiting clamp 6, realizing the clamping or loosening action of the automotive parts. When the limiting clamp 6 clamps and fixes the automotive parts, the anti-slip pad 17 can increase the friction between the limiting clamp 6 and the automotive parts, preventing the automotive parts from sliding or shifting during the welding process, ensuring the accuracy and stability of the welding, and improving the welding quality. The protective eye plate can be moved by starting the electric telescopic rod 8. The lifting mechanism 11 is suitable for parts of different sizes. The protective eye plate 11 is rotatably connected to the support plate 9, allowing operators to adjust the tilt angle of the protective eye plate 11 according to the welding position and angle to obtain the best protection effect. The protective lens inside the protective eye plate 11 can effectively reduce the arc light generated during welding and filter infrared and ultraviolet rays to protect the operator's eyes. When the support plate 9 is raised and lowered with the electric telescopic rod 8, it does not contact the limit clamp 6, avoiding interference between the two and ensuring the normal operation of the fixture. When it is necessary to adjust the angle of the protective eye plate 11, the threaded cap 16 can be loosened first, allowing the protective eye plate 11 to rotate around its rotatable connection point with the support plate 9. After adjusting to the appropriate angle, the threaded cap 16 is tightened. The threaded cap 16 moves on the threaded rod 15 and fits tightly with the semi-circular block 10, thereby fixing the protective eye plate 11 at the current angle and ensuring that the protective eye plate 11 can stably provide protection during welding. It is convenient to operate and has better practicality. The external spiral opening angle of the threaded rod 15 is 20°. The degree, and the thread self-locking condition is calculated according to the following formula: self-locking condition = friction coefficient * tan (helix angle) ≥ 1.
