Description

Technical Field

[0001] The utility model belongs to the technical field of anti-collision beam welding, and in particular relates to a welding fixture for an automobile anti-collision beam. Background Art

[0002] The anti-collision beam is a device used to reduce the impact energy of the vehicle when it is hit by a collision. It consists of a main beam, an energy absorption box and a mounting plate connected to the car. The main beam and the energy absorption box can effectively absorb the collision energy when the vehicle collides at a low speed, and minimize the damage of the impact force to the longitudinal beam of the vehicle body, thereby playing a protective role for the vehicle.

[0003] In order to ensure that the energy of the car's anti-collision beam can be evenly distributed to both ends and absorbed by the energy absorption boxes when it is hit, two sets of energy absorption boxes need to be welded to both sides of the main beam respectively, and the welding process requires the use of clamps for fixing.

[0004] The prior art discloses a patent application with the patent name "Jig for welding automobile anti-collision beams", application number 201710934600.9, and application publication date 2018.01.30, which includes a supporting base plate, a first positioning device for fixing and positioning the anti-collision body, a second positioning device for fixing and positioning the connecting beam, and a third positioning device for positioning the bending part. The first positioning device, the second positioning device, and the third positioning device are fixedly connected to the supporting base plate. By arranging the first positioning device for fixing and positioning the anti-collision body, the second positioning device for fixing and positioning the connecting beam, and the third positioning device for positioning the movement of the bending part, the automobile anti-collision beam and the connecting beam are ensured to be firmly fixed and accurately positioned.

[0005] However, in the above-mentioned prior art, the structure of the clamp is fixed, which makes it inconvenient to adjust the angle of the anti-collision beam. Therefore, welding can only be performed at a fixed angle. There are some dead angles that are not convenient for welding, causing trouble during use and low welding efficiency.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0026] The specific embodiments are as follows:

[0027] Example 1, as Figure 1-5 The figure shows a welding fixture for an automotive anti-collision beam. The fixture comprises a frame, a fixture support plate 2, a clamping assembly 1, and an angle adjustment assembly. The frame includes two longitudinal beams 3, spaced apart and arranged parallel to each other. A rotating shaft is provided at each end of the fixture support plate 2, connected to the longitudinal beams 3 via a bearing assembly. The clamping assembly 1 is positioned above the fixture support plate 2 to secure the anti-collision beam.

[0028] In this embodiment, the clamping assembly 1 includes two symmetrically arranged positioning members, which are L-shaped as a whole and can be adjusted in height to compact the anti-collision beam; the L-shaped positioning member is adjustably connected to the clamp support plate 2, and the distance between the two positioning members can be adjusted to fix and adapt to anti-collision beams of different sizes.

[0029] An angle adjustment component is provided below the clamp support plate 2 for adjusting the rotation angle of the clamp support plate 2 to facilitate the rotation of the anti-collision beam provided on the clamp support plate 2 and expose a suitable angle for welding.

[0030] The angle adjustment assembly includes an adjustment member, a linkage rod 8, a gear 9 and a locking member. In this embodiment, the adjustment member is a plate-shaped adjustment plate 7, which is slightly narrower than the clamp support plate 2 and is vertically connected to the bottom of the clamp support plate 2. The linkage rod 8 is vertically connected to the end of the adjustment plate 7 and can rotate relative to the adjustment plate 7. A gear 9 is coaxially arranged on the linkage rod 8. A semicircular adjustment groove 4 is provided on the longitudinal beam 3 on the side close to the linkage rod 8, and an adjustment tooth 5 is provided along the arc in the adjustment groove 4, and the adjustment tooth 5 can engage with the gear 9; and the adjustment groove 4 is coaxial with the rotating shaft of the clamp support plate 2. The linkage rod 8 passes through the adjustment groove 4 horizontally and aligns and engages with the adjustment tooth 5. Based on this, the gear 9 is rotated and meshed with the adjusting tooth 5, so that the gear 9 moves along the adjusting tooth 5, and the gear 9 drives the linkage rod 8 to move along the adjusting tooth 5. Since the adjusting plate 7 is vertically connected to the clamp support plate 2, the adjusting plate 7 and the clamp support plate 2 are driven to rotate around the rotating axis to achieve adjustment of the angle of the clamp support plate 2.

[0031] A locking member is located on the end of the adjustment plate 7 where the linkage rod 8 is located, and is used to lock the gear 9 to prevent rotation. The locking member can reciprocate at the end of the adjustment plate 7, moving closer to or further away from the gear 9. The end of the locking member near the gear 9 is provided with locking teeth 14, which can mesh with the gear 9. When the locking member approaches the gear 9 and the locking teeth 14 engage the gear 9, the gear 9 is locked and prevented from rotating, thereby fixing the rotation angle of the fixture support plate 2 and allowing welding.

[0032] When the automobile anti-collision beam welding fixture of this embodiment is in use, the anti-collision beam is fixed on the fixture support plate 2 through the clamping component 1. During welding, if the angle of the anti-collision beam needs to be adjusted, the gear 9 is rotated, and the gear 9 moves along the adjusting tooth 5, thereby driving the fixture support plate 2 to rotate. After rotating to a suitable angle, the locking piece is adjusted to be close to the gear 9, and the locking tooth 14 on the locking piece engages with the gear 9 to achieve locking and anti-rotation, thereby fixing the angle of the fixture support plate 2 to facilitate welding at various suitable angles and improve welding efficiency.

[0033] Furthermore, an L-shaped adjustment handle 10 is provided at the end of the linkage rod 8 passing through the adjustment slot 4, so that the user can grasp and apply force, making it more convenient to use.

[0034] Furthermore, a bearing assembly (not shown in the figure) is passed between the linkage rod 8 and the adjustment plate 7 to enable the linkage rod 8 to rotate relative to the adjustment plate 7 .

[0035] Furthermore, the locking member includes an overhanging plate 11, a driving unit 12, and a locking block 13. The overhanging plate 11 is vertically connected to the end of the adjustment plate 7. The driving unit 12 is vertically connected to the overhanging plate 11, and the locking block 13 is connected to the movable end of the driving unit 12. The driving unit 12 can drive the locking block 13 to move back and forth, approaching or moving away from the gear 9. The end of the locking block 13 near the gear 9 is provided with an arc-shaped groove, and the locking teeth 14 are set in the arc-shaped groove to better engage with the gear 9.

[0036] Furthermore, the driving portion 12 adopts a hydraulic cylinder, and the reciprocating drive of the locking block 13 is achieved by controlling the extension and contraction of the hydraulic cylinder, which is more convenient to use and more reliable in locking the gear 9 to prevent rotation.

[0037] Furthermore, the angle adjustment assembly also includes an auxiliary support, which is adjustably connected to the longitudinal beam 3 on the side away from the linkage rod 8 to ensure the stability of the clamp support plate 2 when it is rotated or locked. The auxiliary support includes a support column 15 and a rolling bearing 16. The support column 15 is vertically connected to the end of the adjustment plate 7 away from the linkage rod 8, and the rolling bearing 16 is coaxially arranged on the support column 15. A semicircular slide groove 6 is provided on the longitudinal beam 3 on the side close to the support column 15, and the rolling bearing 16 is connected to the slide groove 6. When adjusting the rotation angle of the clamp support plate 2, the rolling bearing 16 rolls in the slide groove 6 to provide auxiliary support for the clamp support plate 2.

[0038] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
