Description

Technical Field

[0001] The present invention relates to the technical field of friction welding tooling, and particularly to a friction welding pressing plate hoisting device for a new energy battery box body. Background Art

[0002] With the rapid development of new energy vehicles, as the core component, the performance and safety of power batteries have attracted much attention. As the load-bearing structure of power batteries, the welding quality of the battery box body directly affects the safety and service life of the batteries. As an efficient and reliable welding method, friction welding has been widely used in the manufacturing of battery box bodies.

[0003] During the friction welding process of the battery box body, it is necessary to press the pressing plate against the battery box body to ensure the stability and welding quality during the welding process. The traditional hoisting method of the pressing plate mainly uses manual operation, which has the following defects:

[0004] 1. Low efficiency and high labor intensity of manual operation. The battery box body is large in volume and heavy in weight. Manual hoisting of the pressing plate requires the cooperation of multiple people, with low efficiency and potential safety hazards.

[0005] 2. It is easy to cause the pressing plate to collide with the cooling plate, affecting the welding quality. It is difficult to accurately control the movement trajectory of the pressing plate by manual operation, which easily leads to the collision between the pressing plate and the cooling plate, causing deformation or damage to the cooling plate, and thus affecting the welding quality. Summary of the Invention

The middle parts of the first connecting rod and the second connecting rod are hinged together, and both ends of the first connecting rod and the second connecting rod are respectively hinged to the upper substrate and the lower substrate.

[0026] The present invention will be further described below in conjunction with the embodiments and the drawings.

[0027] The friction welding pressure plate lifting device for the new energy battery box body described in this embodiment is mainly used for lifting Figure 2 the pressure plate 15 shown in the figure. Four brackets 16 are fixedly installed on the top of the pressure plate 15, and positioning holes 16a are formed on each of the brackets 16.

[0028] As Figure 1 and Figure 3 shown, a friction welding pressure plate lifting device for a new energy battery box body includes a mounting frame 19. A upper substrate 1 is fixedly installed on the mounting frame 19, and a lower substrate 2 is arranged below the upper substrate 1. The lower substrate 2 can move up and down below the upper substrate 1. A connecting rod assembly is arranged between the upper substrate 1 and the lower substrate 2, and the connecting rod assembly is used to enable the lower substrate 2 to move up and down stably. A chain traction assembly is also arranged on the mounting frame 19. The chain traction assembly is connected to the lower substrate 2 and is used to drive the lower substrate 2 to move up and down relative to the upper substrate 1. An adapter assembly is fixedly installed on the lower substrate 2, and the adapter assembly is used to fixedly clamp the pressure plate 15.

[0029] With such a design, by fixedly clamping the pressure plate through the adapter assembly and then using the cooperation of the chain traction assembly and the connecting rod assembly, the lower substrate 2 can move up and down stably relative to the upper substrate 1, thereby realizing the stable lifting of the pressure plate 15.

[0030] As Figure 1 shown, the chain traction assembly includes a lifting cylinder 4, a chain 5 and a pulley component. Among them, the lifting cylinder 4 is fixedly arranged on the mounting frame 19, and the pulley component is fixedly installed on the upper substrate 1. The two ends of the chain 5 are respectively fixedly connected to the lifting cylinder 4 and the lower substrate 2, and the middle part of the chain 5 is wound around the pulley component.

[0031] Furthermore, the pulley component includes a first pulley 6 and a second pulley 7. An avoidance hole 1a is formed on the top of the upper substrate 1. The first pulley 6 and the second pulley 7 are oppositely arranged at both ends of the avoidance hole 1a. The installation position of the lifting cylinder 4 is located above the first pulley 6. With such a design, through the avoidance hole 1a, it is convenient for the chain 5 to pass through downward and be connected to the lower substrate 2.

[0032] In this embodiment, two chains 5 are connected between the lifting cylinder 4 and the lower substrate 2. Each chain 5 corresponds to a set of pulley components. And in this embodiment, a connecting block 17 is fixedly installed in the middle of the lower substrate 2. The second pulley 7 is vertically arranged on the top of the connecting block 17, and the chain 5 is vertically connected to the top of the connecting block 17 after passing around the second pulley 7. With such a design, through the design of the fixed pulley, it can be ensured that the traction force received by the lower substrate 2 is always in the vertical state, and the two groups of chains 5 can ensure that the chain traction assembly pulls more stably.

[0033] As Figure 4 andFigure 5 As shown in the figure, the connecting rod assembly includes a first connecting rod 8 and a second connecting rod 9. The middle parts of the first connecting rod 8 and the second connecting rod 9 are hinged together, and the two ends of the first connecting rod 8 and the second connecting rod 9 are respectively hinged to the upper substrate 1 and the lower substrate 2. Designing the connecting rod assembly into an X-shaped structure can make the connection between the upper substrate 1 and the lower substrate 2 more stable.

[0034] Furthermore, on the inner side of the upper substrate 1, a first support rod 10 and a second support rod 11 are arranged in parallel. The first support rod 10 is rotatably arranged on the inner side of the upper substrate 1, and the second support rod 11 can move along the length direction of the upper substrate 1. On the inner side of the lower substrate 2, a third support rod 12 and a fourth support rod 13 are arranged in parallel. The third support rod 12 is rotatably arranged on the inner side of the lower substrate 2, and the fourth support rod 13 can move along the length direction of the lower substrate 2. The two ends of the first connecting rod 8 are respectively hinged to the first support rod 10 and the fourth support rod 13, and the two ends of the second connecting rod 9 are respectively hinged to the second support rod 11 and the third support rod 12.

[0035] Still further, on the inner side of the upper substrate 1, a first strip-shaped groove 1b extending along its length direction is formed. The two ends of the second support rod 11 are slidably supported in the first strip-shaped groove 1b. Similarly, on the inner side of the second support rod 2, a second strip-shaped groove 2a extending along its length direction is provided. The two ends of the fourth support rod 13 are slidably arranged in the second strip-shaped groove 2a.

[0036] Through the slidable second support rod 11 and fourth support rod 13, it is ensured that the lower substrate 2 can move up and down relative to the upper substrate 1, and the X-shaped connecting rod assembly makes the upward movement of the lower substrate 2 more stable.

[0037] As Figure 6 shown, the connecting component includes four groups of cylinders 14 fixedly installed on the upper side of the lower substrate. The cylinder rods of two of the cylinders 14 face the left side of the lower substrate 2, and the cylinder rods of the other two cylinders 14 face the right side of the lower substrate 2. The end of each cylinder rod is connected with a positioning pin 3, and the positioning pins 3 are all used to penetrate into the positioning holes 16a. Designed in this way, by telescoping the cylinders 14, the grasping of the pressing plate 15 can be realized, and the overall operation is very convenient.

[0038] Again, as Figure 3 and Figure 4 shown, around the bottom of the lower substrate 2, vertical downward extending limiting blocks 18 are respectively formed. The limiting blocks 18 can support on the top of the pressing plate 15. When the limiting blocks 18 support on the top of the pressing plate 15, the driving cylinders 14 extend, and the positioning pins 3 can just penetrate into the positioning holes 16a. Designed in this way, it is convenient to easily grasp the pressing plate 15.

[0039] Based on the above structure, by driving the extension of the driving cylinder 14, each positioning pin 3 can be inserted into the positioning hole 16a. Then, by lifting the lifting cylinder 4 upward, under the combined action of the chain 5 and the X-shaped connection structure, the lower substrate 2 can be stably moved upward relative to the upper substrate 1, thereby realizing the hoisting of the pressing plate 15. When the pressing plate 15 needs to be used, only by driving the lifting cylinder to move downward, the pressing plate 15 can be placed on the liquid cooling plate, and then the positioning pin 3 can be disengaged from the positioning hole 16a by the cylinder 14.

[0040] Finally, it should be noted that the above description is only the preferred embodiment of the present invention. Under the inspiration of the present invention, those of ordinary skill in the art can make various similar representations without violating the purpose and claims of the present invention, and such transformations all fall within the protection scope of the present invention.
