Description

Technical Field

[0001] This utility model relates to the field of bumper technology, specifically to a welding fixture for automotive bumpers. Background Technology

[0002] Bumpers are located at the front and rear of a car. They serve multiple functions, including safety protection, vehicle decoration, and improving aerodynamics. In low-speed collisions, they act as a buffer, protecting the front and rear of the vehicle. In accidents involving pedestrians, they can also provide some protection. They are decorative, becoming an important component in enhancing the car's appearance. Simultaneously, car bumpers also have aerodynamic benefits. A bumper typically consists of an outer panel, cushioning material, and a crossbeam. The outer panel and cushioning material are attached to the crossbeam, which is bolted to the longitudinal beams of the vehicle frame. During production, car bumpers require assembly and welding, and are usually secured using clamps.

[0003] The existing technology has the following problems:

[0004] 1. Traditional bumper welding fixtures have fixed welding positions and angles, which means that the bumper needs to be repositioned and clamped when welding different planes of the bumper, resulting in a lack of guaranteed welding efficiency.

[0005] 2. Traditional bumpers are usually symmetrical and irregular in shape at both ends, which means that the clamps can only clamp bumpers of a fixed size, thus affecting the clamping efficiency. At the same time, the vibration energy generated during welding can cause the bumper to loosen from the clamping surface of the clamp. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an automotive bumper welding fixture that solves the problems of fixed clamping angle and fixed clamping size mentioned in the background technology.

[0017] Compared with the prior art, the present invention provides a welding fixture for automobile bumpers, which has the following advantages:

[0018] 1. This automotive bumper welding fixture uses a first motor to drive a synchronous pulley to rotate. The rotation of the synchronous pulley drives the synchronous belt and connecting pulley to rotate synchronously. At this time, two sets of first threaded rods drive the movable block to rise and fall. The rise and fall of the movable block drives the clamping seat to rise and fall, adjusting the welding height of the bumper. Simultaneously, a second motor is started to drive the connecting block and electric telescopic rod to rotate. At the same time, the electric telescopic rod drives the bumper on the surface of the clamping seat to rotate, thereby adjusting the welding angle of the bumper and ensuring the convenience of full-body welding of the bumper.

[0019] 2. This automotive bumper welding fixture, when the clamping seat is moved to the appropriate clamping position by two sets of electric telescopic rods, places the bumper on the surface of the clamping seat. At this time, rotating the rotating wheel drives the second threaded rod to rotate, and the rotation of the second threaded rod drives the two sets of clamping blocks to clamp the two ends of the bumper. Then, the electric push rod drives the abutment block to contact the surface of the bumper, achieving the effect of adapting and positioning bumpers of different sizes. At the same time, during the welding of the bumper, the baffle contacts the surface of the bumper to absorb vibration energy and compress the connecting spring, and the damping rod absorbs the rebound energy of the connecting spring, ensuring the stability of the bumper clamped and welded in the clamping seat.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5In this embodiment: a car bumper welding fixture includes a connecting seat 1, an adjusting component 3 is fixedly connected to one end of the connecting seat 1, a movable block 2 is slidably connected to one side of the connecting seat 1, and a clamping component 4 is fixedly connected to one side of the movable block 2.

[0028] The adjustment assembly 3 includes a first motor 31 fixedly connected to the top of the connecting base 1, and a synchronous pulley 32 fixedly connected to the output end of the first motor 31;

[0029] The clamping assembly 4 includes an electric telescopic rod 41 fixedly connected to one side of the movable block 2. The movable end of the electric telescopic rod 41 is fixedly connected to a clamping seat 42, ensuring that the synchronous wheel 32 and the connecting wheel 34 are driven to rotate synchronously by the first motor 31. At the same time, the first threaded rod 35 rotates to adjust the height of the bumper on the surface of the movable block 2 and the clamping seat 42. Meanwhile, the second motor 36 drives the connecting block 37 to rotate to adjust the angle of the bumper. Then, by placing the bumper on the surface of the clamping seat 42, the rotating wheel 45 drives the second threaded rod 46 to clamp the two sides of the bumper. At the same time, the electric push rod 43 drives the abutment block 44 to clamp the bumper surface, achieving the clamping and positioning effect of the bumper.

[0030] In this embodiment, the adjustment component 3 also includes a timing belt 33. The timing belt 33 is meshed with the surface of the timing pulley 32, and a connecting pulley 34 is meshed with the inner side of the timing belt 33. A first threaded rod 35 is fixedly connected to one end of the connecting pulley 34, and a movable block 2 is threadedly connected to the surface of the first threaded rod 35. A second motor 36 is fixedly connected to one side of the movable block 2, and a connecting block 37 is fixedly connected to the output end of the second motor 36. By setting the adjustment component 3, it is ensured that the first motor 31 drives the timing pulley 32 and the connecting pulley 34 to rotate synchronously. At the same time, the first threaded rod 35 rotates to adjust the height of the movable block 2 and the bumper on the surface of the clamping seat 42, and the second motor 36 drives the connecting block 37 to rotate to adjust the angle of the bumper.

[0031] The clamping assembly 4 also includes an electric push rod 43. The electric push rod 43 is fixedly connected to the top of the clamping seat 42. The movable end of the electric push rod 43 is fixedly connected to an abutment block 44. A rotating wheel 45 is rotatably connected to one side of the clamping seat 42. A second threaded rod 46 is fixedly connected to one end of the rotating wheel 45. A clamping block 47 is threadedly connected to the surface of the second threaded rod 46. A fixing block 48 is fixedly connected to the bottom of the clamping seat 42. A damping rod 49 is fixedly connected to the top of the fixing block 48. A connecting spring 410 is fixedly connected to one side of the damping rod 49. A baffle 411 is fixedly connected to one end of the connecting spring 410. A positioning block 412 is rotatably connected to one end of the baffle 411. By setting the clamping assembly 4, the bumper is ensured to be placed on the surface of the clamping seat 42. At the same time, rotating the rotating wheel 45 drives the second threaded rod 46 to clamp the clamping block 47 on both sides of the bumper. Simultaneously, the electric push rod 43 drives the abutment block 44 to clamp the bumper surface, achieving the clamping and positioning effect of the bumper.

[0032] There are two sets of movable blocks 2, and the movable blocks 2 are located on the same plane. The movable blocks 2 are symmetrically distributed on both sides of the connecting seat 1. This ensures that when the first motor 31 drives the synchronous wheel 32 and the connecting wheel 34 to rotate synchronously, the two sets of first threaded rods 35 rotate synchronously to raise and lower the two sets of movable blocks 2 synchronously, thus ensuring the stability of the lifting and lowering of the bumper on the surface of the clamping seat 42.

[0033] The connecting block 37, the electric telescopic rod 41, and the clamping seat 42 are all on the same vertical line. The diameter of the clamping seat 42 is larger than the diameter of the connecting block 37, and the diameter of the connecting block 37 is larger than the diameter of the electric telescopic rod 41. This ensures that when the second motor 36 drives the connecting block 37 to rotate, the connecting block 37 drives the electric telescopic rod 41 and the clamping seat 42 to rotate synchronously. This also ensures that the welding angle of the bumper on the surface of the clamping seat 42 can be flexibly adjusted.

[0034] The abutment block 44 is made of spring steel. The abutment block 44 and the baffle 411 are on the same vertical line. The size of the baffle 411 is matched with the size of the abutment block 44, which ensures that the abutment block 44 has high elastic limit, fatigue strength and yield strength characteristics, and ensures that the abutment block 44 can be used for clamping and positioning on bumpers with uneven surfaces.

[0035] The second threaded rod 46 has two sets of threads symmetrically distributed on its surface, and two sets of clamping blocks 47 are symmetrically distributed on the surfaces of the two sets of threads. This ensures that when the rotating wheel 45 rotates, the second threaded rod 46 rotates and drives the two sets of clamping blocks 47 to move symmetrically, achieving a clamping effect on both sides of the bumper and ensuring that the position of the bumper will not shift when the abutting block 44 abuts against the surface of the bumper.

[0036] The working principle and usage process of this utility model: This utility model is a welding fixture for automobile bumpers. When it is necessary to adjust the welding height and angle of the bumper, the first motor 31 drives the synchronous pulley 32 to rotate. The synchronous pulley 32 rotates, causing the synchronous belt 33 and the connecting pulley 34 to rotate synchronously. At this time, the two sets of first threaded rods 35 drive the movable block 2 to rise and fall. The rising and falling of the movable block 2 causes the clamping seat 42 to rise and fall, adjusting the welding height of the bumper. Simultaneously, the second motor 36 is started, driving the connecting block 37 and the electric telescopic rod 41 to rotate. The electric telescopic rod 41 also drives the bumper on the surface of the clamping seat 42 to rotate, thereby adjusting the welding angle of the bumper and ensuring convenient full-body welding of the bumper. Meanwhile, when it is necessary to clamp and position bumpers of different sizes, the clamping seat 42 is moved to the appropriate clamping position by two sets of electric telescopic rods 41. The bumper is placed on the surface of the clamping seat 42. At this time, the rotating wheel 45 drives the second threaded rod 46 to rotate. The rotation of the second threaded rod 46 drives the two sets of clamping blocks 47 to clamp the two ends of the bumper. Then, the electric push rod 43 drives the abutment block 44 to contact the surface of the bumper, achieving the effect of adapting and positioning bumpers of different sizes. At the same time, when the bumper is welded, the baffle 411 contacts the surface of the bumper to absorb vibration energy and compress the connecting spring 410. The damping rod 49 absorbs the rebound energy of the connecting spring 410, ensuring the stability of the bumper clamped and welded in the clamping seat 42.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
