Description

Technical Field

[0001] This utility model relates to the field of welding fixtures, specifically to an adjustment device for a welding fixture for an automobile fender mounting plate. Background Technology

[0002] The car fender is the outer body panel that covers the wheels. It gets its name from the bird-wing-like shape and position of this component on older models. For aerodynamic reasons, some fenders are slightly arched during production, and one end protrudes outwards. When drilling holes in the fender or welding it to a mounting plate, it needs to be secured. Due to the irregular shape of the fender, traditional clamps cannot hold and secure it in all positions. Currently, most systems use vertical clamps to press and fix the fender to the worktable. Existing technology uses a vertical clamp mainly composed of a fixed base, connecting arm, handle, adjusting screw, and pressure head. During installation, the bottom of the fixed base is fixed to the worktable via a base (which can be bolted). One end of the connecting arm is hinged to the middle of the fixed base. The hinge has a handle, which is also hinged to one end of the connecting arm. A long slot is provided on the side of the connecting arm away from the hinge end. A sliding plate with a central opening is slidably connected to the outside of the long slot. The adjusting screw can pass through the sliding plate and the long slot, allowing the adjusting screw to slide and adjust its position within the long slot via the sliding plate. It is then secured with bolts. A rubber pressure head is installed at the bottom of the adjusting screw. When pressure is needed on the fender, the handle can be pushed upwards to a vertical position. At this time, the connecting arm will rotate downwards, causing the pressure head at the lower end of the adjusting screw to press against the fender (the position and height of the adjusting screw can be adjusted according to the thickness of the fender beforehand). When the fender needs to be released, the handle can be pulled downwards to a horizontal position. At this time, the connecting arm will rotate upwards, lifting the adjusting screw and pressure head away from the fender.

[0003] Currently, some car fenders are made of aluminum alloy or composite plastic to reduce weight. When using vertical clamps, they are mostly used to press and fix flat parts of the sheet metal. Since the overall shape of the fender is irregular, some parts are arched, and some parts are protruding. In the existing technology, the pressing surface of the clamping head is flat. When the clamping head is used to press directly on these parts, if the pressing force is too tight, it is easy to cause the arched or protruding parts of the fender to be deformed. If the pressing force is too loose, it cannot be clamped tightly, causing the fender to slip between the clamping head and the fender, affecting the overall welding effect.

[0004] Therefore, it is necessary to invent an adjustment device for welding fixtures of automobile fender mounting plates. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustment device for a welding fixture of an automobile fender mounting plate, comprising a fixed base, a connecting arm, and an adjusting screw. One end of the connecting arm is hinged to the fixed base in the middle, and the adjusting screw is connected in the middle of the end of the connecting arm away from the fixed base. A fixed plate is fixedly installed at the lower end of the adjusting screw, and a connecting plate is installed at the lower end of the fixed plate. An adjusting plate is hinged to the lower end of the connecting plate, and reinforcing components are movably connected to both ends of the adjusting plate.

[0007] Based on the above features: the adjustment plate can be rotated and adjusted in the middle of the connecting plate to form a 7-shaped structure or an inverted V-shaped structure, which facilitates flexible adjustment and limits the fixing of the flat part, arched or protruding part of the fender.

[0008] Preferably, the fixed plate has symmetrical movable grooves on both sides, a through hole in the middle of the lower end of the fixed plate, a first magnet is fixedly installed at the top of the inner cavity of the fixed plate, and a plug rod is movably inserted into the through hole.

[0009] Based on the above features, the insertion rod can extend downward through the through hole to limit and fix the adjusting plate.

[0010] Preferably, the lower end of the inner cavity of the fixing plate is a hollow structure.

[0011] Based on the above features, the insertion rod can retract into the cavity of the hollow fixed plate when it rises.

[0012] Preferably, a baffle is fixedly installed at the upper end of the insertion rod, a second magnet is fixedly installed at the middle of the upper end of the baffle, and positioning rods are symmetrically installed on both sides of the baffle.

[0013] Based on the above features: the insertion rod can be pulled upward by the positioning rod at the outer end of the fixed plate. When the positioning rod is released, the first magnet will repel and rebound the second magnet, causing the insertion rod to move downward and extend through the through hole.

[0014] Preferably, the adjustment plate includes a horizontal plate and a vertical plate, the horizontal plate and the vertical plate are an integral structure, and the horizontal plate and the vertical plate are arranged in a figure-7 shape.

[0015] Based on the above characteristics: when the adjustment plate composed of the horizontal plate and the vertical plate has a 7-shaped structure, it can press the flat part of the fender; when the horizontal plate and the vertical plate have an inverted V-shaped structure, it can press and limit the arched or protruding part of the fender.

[0016] Preferably, a first insertion hole is provided on one end surface of the adjustment plate, and a second insertion hole is provided in the middle of the adjustment plate.

[0017] Based on the above features: when the plug is inserted into the first socket, it can fix the 7-shaped adjustment plate; when the plug is inserted into the second socket, it can fix the inverted V-shaped adjustment plate, preventing the adjustment plate from rotating on its own.

[0018] Preferably, the reinforcement component includes a first pressure roller and a second pressure roller, with a connecting shaft installed between the first pressure roller and the second pressure roller.

[0019] Based on the above features: when it is necessary to press and fix the flat plate-shaped part of the fender, the first pressure roller below the vertical plate presses and fixes it above the flat fender. When it is necessary to press and limit the arched or protruding part of the fender, the adjustment plate can be rotated to form an inverted V-shaped structure, which makes it convenient for the horizontal plate and the vertical plate to be pressed and fixed on both sides of the arched or protruding part of the fender by the first and second pressure rollers at one end.

[0020] The beneficial effects of this utility model are:

[0021] 1. The adjustable plate and reinforcing components facilitate the limiting and fixing of the flat, arched, or protruding parts of the fender. When it is necessary to press and fix the flat plate-like part of the fender, the adjustable plate composed of the horizontal and vertical plates has a 7-shaped structure, which facilitates the first pressure roller below the vertical plate to press and fix it on the flat fender. When it is necessary to press and limit the arched or protruding parts of the fender, the adjustable plate can be rotated to form an inverted V-shaped structure, which facilitates the horizontal and vertical plates to press and fix them on both sides of the arched or protruding parts of the fender using the first and second pressure rollers at one end, thus minimizing the deformation of the arched or protruding parts of the fender.

[0022] 2. By using the insertion rod in conjunction with the first and second insertion holes, the adjustment plate can be fixed in a limited position. When the insertion rod is inserted into the first insertion hole, it can fix the 7-shaped adjustment plate. When the insertion rod is inserted into the second insertion hole, it can fix the inverted V-shaped adjustment plate, preventing the adjustment plate from rotating on its own.

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] See attached document Figure 6 The existing product structure includes a vertical clamp consisting of a fixed base 1, a connecting arm 2, and an adjusting screw 3. The bottom of the fixed base 1 is fixed to the workbench via a base (which can be bolted). One end of the connecting arm 2 is hinged to the middle of the fixed base 1. A handle is hinged to the outside of the fixed base 1. The handle is also hinged to one end of the connecting arm 2. A long slot is provided on the side of the connecting arm 2 away from the hinge end. A sliding plate with a central opening is slidably connected to the outside of the long slot. The adjusting screw 3 can pass through the sliding plate and the long slot, allowing the adjusting screw 3 to slide and adjust its position within the long slot via the sliding plate. It is then locked in place with bolts. When it is necessary to press the fender, the handle can be pushed upward to become vertical. At this time, the connecting arm 2 will rotate downward, causing the pressure head at the lower end of the adjusting screw 3 to press on the fender. (When it is necessary to release the fender, the handle can be pulled downward to become horizontal. At this time, the connecting arm 2 will rotate upward, causing the adjusting screw 3 to lift away from the fender.)

[0032] See attached document Figure 1-4This utility model provides an adjustment device for a welding fixture of an automobile fender mounting plate. A fixing plate 4 is fixedly installed at the lower end of an adjusting screw 3. Connecting plates 5 are installed on both sides of the lower end of the fixing plate 4 (the fixing plate 4 and the connecting plates 5 are fixed together by bolts). An adjusting plate 6 is hinged to the middle of the lower end of the connecting plate 5. Symmetrical holes for hinged connections are provided on both ends of the connecting plate 5 to the fixing plate 4 and the adjusting plate 6. The adjusting plate 6 includes a horizontal plate and a vertical plate, which are integrally formed. The structure includes a reinforcing assembly 7 movably connected to both ends of the adjusting plate 6. The reinforcing assembly 7 includes a first pressure roller 71 and a second pressure roller 72. The first pressure roller 71 is connected to one end of the vertical plate via a connecting shaft 73 (and the bottom surface of the first pressure roller 71 is flat). The second pressure roller 72 is connected to one end of the horizontal plate via a connecting shaft 73. When it is necessary to press and fix the flat plate-like part of the fender, the horizontal plate and the vertical plate are arranged in a "7" shape, so that the first pressure roller 71 below the vertical plate presses and fixes the flat plate above the fender (see [reference]). Figure 1 );

[0033] When it is necessary to press and limit the arched or protruding parts of the fender, the adjusting plate 6 can be rotated (the rotation angle can be between 30-45 degrees) to make the horizontal and vertical plates form an inverted V-shaped structure (see...). Figure 4 At this point, a 30-45 degree angle will be formed between the horizontal plate and the vertical plate, which makes it convenient for the horizontal plate and the vertical plate to be pressed and fixed on both sides of the arched or raised part of the fender by the first pressure roller 71 and the second pressure roller 72 at one end (the first pressure roller 71 and the second pressure roller 72 roll and rub against the arched or raised part of the fender). The arched or raised part of the fender will be located between the first pressure roller 71 and the second pressure roller 72, so as to avoid the first pressure roller 71 and the second pressure roller 72 directly pressing on the top of the arched or raised part of the fender, thereby causing the fender to be pressed and deformed.

[0034] See attached document Figure 1-5 The lower end of the inner cavity of the fixing plate 4 is hollow. The fixing plate 4 has symmetrical movable grooves 41 on both sides. A through hole 42 is formed in the middle of the lower end of the fixing plate 4. A first magnet 43 is fixedly installed at the top of the inner cavity of the fixing plate 4. A rod 44 is movably inserted into the through hole 42. A baffle 441 is fixedly installed at the upper end of the rod 44. The diameter of the baffle 441 is larger than that of the through hole 42 to prevent the rod 44 from detaching through the through hole 42. A second magnet 442 is fixedly installed in the middle of the upper end of the baffle 441. The second magnet 442 is aligned with the first magnet 43, and their magnetic poles repel each other, ensuring that the first magnet 43 always repels and bounces back the second magnet 442. This allows the rod 44 to extend through the through hole 42 without human intervention. Positioning rods 443 are symmetrically installed on both sides of the baffle 441. A first insertion hole 61 is formed on the surface of the horizontal plate away from the reinforcing component 7. A second insertion hole 62 is formed at the junction of the horizontal plate and the vertical plate.

[0035] When it is necessary to fix the adjustment plate 6 with the 7-shaped structure, the first insertion hole 61 on one side of the horizontal plate will be aligned with the through hole 42, so that the insertion rod 44 can be inserted downward into the first insertion hole 61 to fix the adjustment plate 6 with the 7-shaped structure and prevent the adjustment plate 6 from rotating on its own. When it is necessary to rotate the adjustment plate 6 into an inverted V-shaped structure, the insertion rod 44 can be pulled upward by the positioning rod 443 to disengage from the first insertion hole 61. Then, the adjustment plate 6 is rotated into an inverted V-shaped structure so that the second insertion hole 62 at the junction of the horizontal plate and the vertical plate is aligned with the through hole 42 degrees. Then, the positioning rod 443 is released so that the insertion rod 44 is inserted downward into the second insertion hole 62 to fix the adjustment plate and prevent the adjustment plate 6 with the inverted V-shaped structure from rotating on its own.

[0036] The usage process of this utility model is as follows: When it is necessary to press and fix the flat plate-shaped part of the fender, the horizontal plate and the vertical plate are arranged in a 7-shaped structure. Then, push the handle upward to make it vertical. At this time, the connecting arm 2 will rotate downward and gradually become vertical, so that the first pressure roller 71 below the vertical plate presses and fixes it above the flat fender. When it is necessary to press and limit the arched or protruding part of the fender, the insertion rod 44 can be pulled upward by the positioning rod 443 to make the insertion rod 44 move away from the adjusting plate 6. Then, the adjusting plate 6 can be rotated to make the horizontal plate and the vertical plate form an inverted V-shaped structure. Then, the positioning rod 443 is released, so that the insertion rod 44 moves down and is inserted into the upper part of the adjusting plate 6 for alignment and fixation. The horizontal plate and the vertical plate are pressed and fixed on both sides of the arched or protruding part of the fender by the first pressure roller 71 and the second pressure roller 72 at one end, and the arc or protruding part of the fender will be located between the first pressure roller 71 and the second pressure roller 72.

Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
