Description

Technical Field

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

[0002] The anti-collision beam is a device used to reduce the absorption of collision energy when the vehicle is hit. It is composed 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 to the longitudinal beam of the vehicle body by the impact force. In this way, it plays a protective role for the vehicle. The anti-collision beam of an automobile is generally designed to be a bow-shaped structure that matches the front of the vehicle. During the production and processing of the existing anti-collision beam of an automobile, some parts need to be welded. During welding, the anti-collision beam needs to be fixed and limited in position in order to prevent the anti-collision beam from shifting during welding, resulting in excessive welds or insufficient welding strength. The existing fixing method is mostly to use bolts and pressure plates to fix the anti-collision beam. The entire fixing process requires manual fixing, but this manual fixing method has the following defects: since tools are needed to tighten multiple bolts in sequence, and when a part of the welding needs to flip the welding surface, the bolts need to be removed in sequence, the operation is cumbersome and time-consuming and labor-intensive. Utility Model Content

[0003] In view of the above situation, in order to make up for the deficiencies of the prior art, the purpose of the utility model is to provide an anti-collision beam welding and fixing device, which effectively solves the problem of inconvenient fixing operation of the existing anti-collision beam during welding.

[0004] The technical solution is that the utility model includes a rectangular bottom plate shell, an arc-shaped baffle is provided on the upper end of the bottom plate shell, an anti-collision beam is placed on the upper end of the bottom plate shell and is located in front of the baffle and can contact the baffle, a transverse fixing block is provided on the upper end of the bottom plate shell and is located in front of the anti-collision beam and can move forward and backward, an arc-shaped and movable arc-shaped fixing block is provided on the left and right sides of the upper end of the bottom plate shell respectively, both the transverse fixing block and the arc-shaped fixing block can contact the anti-collision beam, and an L-shaped connecting rod is hinged on the upper end of the bottom plate shell and is located behind the baffle.

[0016] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 6It is given, including a rectangular bottom plate shell 1, an arc-shaped baffle 2 is provided on the upper end of the bottom plate shell 1, an anti-collision beam 3 is placed on the upper end of the bottom plate shell 1 and is located in front of the baffle 2 and can contact the baffle 2, a transverse fixing block 4 is provided on the upper end of the bottom plate shell 1 and is located in front of the anti-collision beam 3 and can move forward and backward, and arc-shaped and movable arc-shaped fixing blocks 5 are respectively provided on the left and right sides of the upper end of the bottom plate shell 1, and the transverse fixing block 4 and the arc-shaped fixing block 5 can both contact the anti-collision beam 3, and the upper end of the bottom plate shell 1 is hinged with an L-shaped connecting rod 6 located behind the baffle 2, the connecting rod 6 can swing and a longitudinal pressing block 7 is provided at the front end which can contact the anti-collision beam 3.

[0018] In order to move the transverse fixing block 4 and the arc fixing block 5, the bottom plate shell 1 is provided with inclined grooves 8 on the left and right sides of the upper end, and the two inclined grooves 8 can form an inverted eight-shaped shape. The top end of the bottom plate shell 1 is provided with a vertical groove 9 located between the two inclined grooves 8. A slider 10 that can move forward and backward is provided in the bottom plate shell 1. The left and right sides of the upper end of the slider 10 are provided with yield grooves 11 respectively. The lower ends of the transverse fixing block 4 and the arc fixing block 5 are respectively provided with plug posts 12. The plug posts 12 at the lower end of the arc fixing block 5 are respectively inserted into the yield grooves 11 on the corresponding sides, and the plug posts 12 at the lower end of the transverse fixing block 4 are fixedly connected to the slider 10.

[0019] In order to facilitate the swing of the connecting rod 6, a waist-shaped groove 13 is opened on the lower side of the connecting rod 6 and runs through the left and right sides. A U-shaped push plate 14 is provided at the rear end of the slider 10, and a top column 15 inserted into the waist-shaped groove 13 is provided on the push plate 14.

[0020] In order to facilitate the swing of the connecting rod 6 , a swing groove 16 is opened at the upper end of the bottom plate shell 1 , and the connecting rod 6 is located in the swing groove 16 .

[0021] In order to enable the slider 10 to slide forward and backward, the slider 10 is slidably connected to the bottom plate shell 1. A motor 17 is provided on the front side wall of the bottom plate shell 1. A stud 18 threadedly connected to the slider 10 is coaxially provided on the output shaft of the motor 17.

[0022] In order to facilitate supporting the bottom plate shell 1, a plurality of cushion blocks are provided at the lower end of the bottom plate shell 1.

[0023] When the utility model is in use, the anti-collision beam 3 is first placed on the bottom plate shell 1 and its rear surface is fitted with the baffle plate 2 to achieve limit positioning. Then, the motor 17 is turned on to rotate forward, and the motor 17 drives the stud 18 to rotate forward. The stud 18 then drives the slider 10 to move backward. The slider 10 drives the horizontal fixing block 4 to move backward through the plug column 12. After moving backward for a distance, the horizontal fixing block 4 contacts with the front surface of the anti-collision beam 3 and realizes backward extrusion and fixation. When the slider 10 drives the horizontal fixing block 4 to move backward, it also drives the plug columns 12 on the left and right sides to move outward in the inclined groove 8, thereby driving the two arc-shaped fixing blocks 5 to move outward. After moving outward for a distance, the two arc-shaped fixing blocks 5 respectively contact with the two sides of the anti-collision beam 3 and squeeze the anti-collision beam 3 outward, but at this time the rear end of the anti-collision beam 3 is blocked by the baffle plate 2, so the clamping and fixation of the anti-collision beam 3 is achieved.

[0024] When the slider 10 moves backward, it also drives the push plate 14 to move backward. The push plate 14 drives the connecting rod 6 to swing downward through the top column 15 and the waist-shaped groove 13. The connecting rod 6 drives the longitudinal pressing block 7 thereon to swing downward. After swinging downward at a certain angle, the longitudinal pressing block 7 contacts the upper end of the anti-collision beam 3 and realizes the downward extrusion and fixation of the anti-collision beam 3, thereby realizing the longitudinal extrusion and fixation of the anti-collision beam 3. Combined with the transverse fixing block 4 and the arc fixing block 5, the anti-collision beam 3 is completely pressed and fixed. At this time, the welding operation can be carried out;

[0025] When the anti-collision beam 3 needs to be turned over and welded, the motor 17 will be started to reverse, and the motor 17 will drive the stud 18 to rotate in the opposite direction, thereby driving the slider 10 to move forward. The slider 10 drives the horizontal fixing block 4 to move forward through the plug column 12 and drives the arc fixing block 5 to move toward the middle. After moving a certain distance, it will break contact with the anti-collision beam 3 and release the fixed limit.

[0026] Compared with the prior art, the beneficial effects of the utility model are: the transverse fixing blocks, arc fixing blocks, etc. are provided, which can realize the longitudinal and transverse fixed limitation of the anti-collision beam, prevent the displacement caused by shaking during welding, resulting in a larger weld, and can automatically fix and release the fixation. Compared with the traditional manual bolt fixing, the operation is simple and time-saving and labor-saving. This structure is simple, the concept is novel, it is easy to use and has strong practicality.

[0027] It should be pointed out that, according to the needs of implementation, the various components described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.

[0028] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
