Description

Technical Field

[0001] This utility model belongs to the field of welding technology for tricycle crash barriers, specifically relating to a fully automatic spherical welding positioning device. Background Technology

[0002] In the tricycle manufacturing industry, the crash barrier at the front of the tricycle frame is an important component to ensure the safety of the vehicle and the lives of the driver and passengers. The crash barrier is usually made of multiple rods and ball joints welded together by a laser welding gun. This structural design can not only effectively absorb and disperse the impact force generated during a collision, but also improve the overall aesthetics of the tricycle to a certain extent.

[0003] Currently, the welding of tricycle crash barriers typically involves manual positioning to prepare the crash barrier components for welding to the spherical joints. Operators rely on their experience and simple auxiliary clamping tools to clamp the components and preliminarily align and fix them with the spherical joints. Then, a laser welding gun is used to weld the joint between the components and the spherical joints. However, this method has significant limitations. The efficiency of manual operation and manual positioning welding is low, which cannot meet the needs of large-scale, high-efficiency production and greatly reduces processing efficiency.

[0022] 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.

[0023] This utility model provides, for example Figure 1-3 The fully automatic spherical welding positioning device shown includes:

[0024] Base 1, with a vertical pole 2 connected to one top end of the base 1 and a horizontal plate 3 connected to the top of the vertical pole 2;

[0025] The base 4 has a rotating block 5 rotatably connected to it via a bearing. The rotating block 5 has a placement groove 7 for placing the spherical shell 6. The top of the base 1 has a movable seat 8, and the top of the movable seat 8 has a clamping assembly for clamping and fixing the straight rod 9. The electric push rod 10 of the clamping assembly pushes the clamping block 11 to move closer to the straight rod 9 so that the clamping blocks 11 that are close to each other clamp the straight rod 9.

[0026] The clamping assembly includes a rotating base 12, several sets of electric push rods 10 are provided and are all located inside the rotating base 12, several sets of clamping blocks 11 are provided and are all located inside the rotating base 12, and one end of the electric push rod 10 is connected to the clamping block 11.

[0027] The top of the movable seat 8 is connected to a fixed seat 13, and a motor 14 is provided inside the fixed seat 13. The output shaft of the motor 14 rotates through the fixed seat 13 and is connected to the rotating seat 12.

[0028] The base 1 has an opening at the top center and a guide rod 15 is connected inside the opening. The movable seat 8 has a slider 16 connected to its bottom.

[0029] The bottom of the slider 16 is movably connected through the opening and then slidably sleeved onto the surface of the guide rod 15. The base 1 is provided with a cylinder 17 and the piston rod of the cylinder 17 is connected to the slider 16 located in the opening. The piston rod of the cylinder 17 can push the slider 16 to slide on the guide rod 15, thereby guiding the movement direction of the slider 16 through the guide rod 15, which can enhance the stability of the slider 16 when it drives the moving seat 8 to move.

[0030] The top of the movable seat 8 is connected to the mounting plate 18, and the top of the mounting plate 18 is connected to the rotating frame 19. Rollers 20 are rotatably connected to both ends of the rotating frame 19. When the straight rod 9 rotates, it can drive the rollers 20 to rotate inside the rotating frame 19, thereby ensuring the stability of the straight rod 9 during the rotation process and avoiding shaking during rotation.

[0031] The bottom of the horizontal plate 3 is equipped with a laser welding gun 21 for welding the joint between the spherical shell 6 and the straight rod 9.

[0032] The clamping block 11 has an arc-shaped groove and a protective pad 22 inside the arc-shaped groove. The protective pad 22 is made of rubber, so that when the clamping block 11 clamps the straight rod 9, the protective pad 22 can prevent the clamping block 11 from damaging the surface of the straight rod 9.

[0033] Before welding, this fully automatic spherical welding positioning device first places the spherical shell 6 in the placement groove 7 of the rotating block 5 inside the stand 4. The design of the placement groove 7 is adapted to the shape of the spherical shell 6, which can initially stabilize the spherical shell 6. The rotating block 5 is rotatably connected to the stand 4 through a bearing. This connection method allows the spherical shell 6 to be easily rotated if the angle needs to be adjusted during the subsequent welding process. When it is necessary to clamp the straight rod 9, one end of the straight rod 9 is placed in the clamping groove 23 of the rotating seat 12, and the electric push rod 10 is controlled by an external controller. The electric push rod 10 pushes the clamping block 11 to move closer to the straight rod 9 and clamp the straight rod 9. The clamping block 11 has an arc-shaped groove, and a protective pad 22 is installed in the arc-shaped groove. The arc-shaped groove can better... The shape of the straight rod 9 is closely fitted, and the protective pad 22 can prevent the clamping block 11 from damaging the surface of the straight rod 9 while clamping it. After the straight rod 9 is clamped, the cylinder 17 can be controlled by an external controller. The piston rod of the cylinder 17 pushes the slider 16 to slide on the guide rod 15. The slider 16 drives the moving seat 8 to move, so that the unclamped end of the straight rod 9 docks with the ball shell 6 in the placement groove 7. When the straight rod 9 docks with the ball shell 6, the proximity sensor (not shown in the figure) installed on the surface of the stand 4 can sense the change in the magnetic field or capacitance of the straight rod 9, thereby generating an electrical signal. This signal is transmitted to the control system of the cylinder 17. The control system commands the cylinder 17 to stop running according to the signal, so that the cylinder 17 can stop working after the straight rod 9 docks with the ball shell 6.

[0034] After the straight rod 9 and the spherical shell 6 are positioned and aligned, the laser welding gun 21 at the bottom of the horizontal plate 3 starts to work. The laser welding gun 21 emits a high-energy laser beam to weld the joint between the spherical shell 6 and the straight rod 9. During the welding process, the motor 14 is controlled by an external controller. The output shaft of the motor 14 drives the rotating seat 12 to rotate slowly. When the rotating seat 12 rotates, it drives the straight rod 9 and the spherical shell 6 to rotate as well, so that the joint between the spherical shell 6 and the straight rod 9 rotates to a suitable welding angle. The joint between the spherical shell 6 and the straight rod 9 is welded from all directions, and the straight rod 9 and the spherical shell 6 are firmly welded together. The rotating seat 12, the rotating frame 19 and the roller 20 on the top of the moving seat 8 play an auxiliary support role during the rotation of the straight rod 9. The straight rod 9 can drive the roller 20 to rotate in the rotating frame 19 when rotating, so as to ensure the stability of the straight rod 9 during the rotation process and avoid wobbling. While supporting the rotation of the straight rod 9, it ensures that the straight rod 9 can accurately align with the spherical shell 6.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
