Description

Technical Field

[0001] This utility model relates to a welding equipment for flow channel plates in a thermal management system. Background Technology

[0002] The flow channel plate of the thermal management system, a key component in the thermal management module of new energy vehicles, is typically composed of a three-layer structure—upper, middle, and lower—fixed together by welding. Currently, welding the flow channel plate involves placing it on a mold and welding it with components such as hot plates and cylinders. This requires two sets of molds: the first mold is used to weld the lower and middle sections, and after they are welded together, they are placed on the second mold to weld the upper section. These two sets of molds require two sets of hot plates and cylinders, resulting in high tooling and equipment costs. Furthermore, currently, when installing the middle section, or the welded middle and lower sections, onto the upper mold, it is only secured by friction between the product and the mold, posing a risk of detachment. When placing the middle section onto the lower mold, two long pins are manually inserted to hold it in place, which is also time-consuming. Utility Model Content

[0003] In view of the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a welding equipment for a thermal management system flow channel plate.

[0004] The technical solution of this utility model is: a welding equipment for a flow channel plate in a thermal management system, comprising an upper module and a lower module. The lower module includes a lower base and a first lower template and a second lower template fixed to the top of the lower base and distributed to the left and right. A middle body and an upper body are respectively placed on the first lower template and the second lower template. An automatic clamping device for clamping the middle body is installed at the upper end of the first lower template. The upper module includes an upper base and a first upper template and a second upper template fixed to the bottom of the upper base and distributed to the left and right. A lower body is placed on the first upper template, and a middle body and a lower body welded together are placed on the second upper template. A retractable first baffle and a second baffle are installed on the upper module, which respectively block the left and right ends of the bottom of the lower body on the first upper template. A retractable third baffle and a fourth baffle are installed on the upper module, which respectively block the left and right ends of the bottom of the lower body on the second upper template.

[0005] Furthermore, the automatic pressing device includes a first pressing cylinder that extends to the left and right and is fixed to the front end of the first lower template, and a first pressure plate that is fixed to the end of the piston rod at the left end of the first pressing cylinder. The front end of the middle body has a first positioning seat, and the first pressure plate presses on the top of the first positioning seat.

[0006] Furthermore, the automatic clamping device also includes a second clamping cylinder that extends to the left and right and is fixed to the rear end of the first lower template, and a second pressure plate that is fixed to the left end of the second clamping cylinder. The rear end of the middle body has a second positioning seat, and the second pressure plate presses on the top of the second positioning seat.

[0007] Furthermore, the lower body has a first protrusion and a second protrusion protruding from its left and right ends, respectively. A first control cylinder extending to the left and right is fixed to the lower left end of the first upper template. The piston rod end of the right end of the first control cylinder is fixedly connected to a first baffle. A second control cylinder arranged obliquely is fixed to the lower right end of the second upper template. The piston rod end of the left end of the second control cylinder is fixedly connected to a second baffle. When the lower body is placed on the first upper template, the first baffle blocks the bottom of the first protrusion, and the second baffle blocks the bottom of the second protrusion.

[0008] Furthermore, a third control cylinder extending to the left and right is fixed at the top right end of the first upper template. The piston rod end of the third control cylinder is fixedly connected to a third baffle. A fourth control cylinder arranged obliquely is fixed at the lower right end of the second upper template. The piston rod end of the fourth control cylinder is fixedly connected to a fourth baffle. When the lower body and middle body welded together are placed on the second upper template, the third baffle blocks the bottom of the first protrusion, and the fourth baffle blocks the bottom of the second protrusion.

[0009] The advantages of using the flow channel plate welding equipment for a thermal management system provided by this utility model are: two welding processes can be achieved through one set of welding equipment, which can save costs, and there is no risk of the flow channel plate falling off. After the middle body is placed on the first lower template, it will be automatically pressed, making the operation more convenient. Attached Figure Description

Detailed Implementation

[0014] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:

[0015] like Figure 1 , Figure 2 As shown, a thermal management system flow channel plate welding device includes an upper module 100 and a lower module 200. The lower module 200 includes a lower base 1 and a first lower template 2 and a second lower template 3 fixed to the top of the lower base 1 and distributed to the left and right. A middle body 4 and an upper body 5 are respectively placed on the first lower template 2 and the second lower template 3. An automatic clamping device for clamping the middle body 4 is installed on the upper end of the first lower template 2. The upper module 100 includes an upper base 6 and a first upper template 7 and a second upper template 7 fixed to the bottom of the upper base 6 and distributed to the left and right. Plate 8, a lower body 9 is placed on the first upper template 7, and a middle body 4 and a lower body 9 welded together are placed on the second upper template 8; an upper module 100 is equipped with a retractable first baffle 10 and a second baffle 11, which respectively block the left and right ends of the bottom of the lower body 9 on the first upper template 7; an upper module 100 is equipped with a retractable third baffle 12 and a fourth baffle 13, which respectively block the left and right ends of the bottom of the lower body 9 on the second upper template 8.

[0016] like Figure 2 As shown, the automatic clamping device includes a first clamping cylinder 14 extending laterally and fixed to the front end of the first lower template 2, and a first pressure plate 15 fixed to the left end of the piston rod of the first clamping cylinder 14. The front end of the middle body 4 has a first positioning seat 41, and the first pressure plate 15 presses against the top of the first positioning seat 41. The automatic clamping device also includes a second clamping cylinder 16 extending laterally and fixed to the rear end of the first lower template 2, and a second pressure plate 17 fixed to the left end of the second clamping cylinder 16. The rear end of the middle body 4 has a second positioning seat 42, and the second pressure plate 17 presses against the top of the second positioning seat 42.

[0017] The first pressing cylinder 14 can control the first pressing plate 15 to move left and right. When the first pressing plate 15 moves to the top of the first positioning seat 41, the first pressing plate 15 presses down on the first positioning seat 41. Similarly, the second pressing cylinder 16 can control the second pressing plate 17 to move left and right. When the second pressing plate 17 moves to the top of the second positioning seat 42, the second pressing plate 17 presses down on the second positioning seat 42. Both the front and rear ends of the middle body 4 are pressed down, so the entire middle body 4 is firmly fixed.

[0018] like Figure 2As shown, the lower body 9 has a first protrusion 91 and a second protrusion 92 protruding from its left and right ends, respectively. The lower left end of the first upper template 7 is fixed with a first control cylinder 18 extending to the left and right. The piston rod end of the right end of the first control cylinder 18 is fixedly connected to the first baffle 10. The lower right end of the second upper template 8 is fixed with a second control cylinder 19 arranged obliquely. The piston rod end of the left end of the second control cylinder 19 is fixedly connected to the second baffle 11. When the lower body 9 is placed on the first upper template 7, the first baffle 10 blocks the bottom of the first protrusion 91, and the second baffle 11 blocks the bottom of the second protrusion 92. A third control cylinder 20 extending to the left and right is fixed at the top right end of the first upper template 7. The piston rod end of the third control cylinder 20 is fixedly connected to the third baffle 12. A fourth control cylinder 21 arranged obliquely is fixed at the lower right end of the second upper template 8. The piston rod end of the fourth control cylinder 21 is fixedly connected to the fourth baffle 13. When the lower body 9 and the middle body 4, which are welded together, are placed on the second upper template 8, the third baffle 12 blocks the bottom of the first protrusion 91, and the fourth baffle 13 blocks the bottom of the second protrusion 92.

[0019] The first control cylinder 18, the second control cylinder 19, the third control cylinder 20, and the fourth control cylinder 21 respectively control the extension and retraction of the first baffle 10, the second baffle 11, the third baffle 12, and the fourth baffle 13. The first baffle 10 and the second baffle 11 are positioned at the left and right ends of the lower body 9, respectively, effectively preventing the lower body 9 from falling off. The third baffle 12 and the fourth baffle 13 are also positioned at the left and right ends of the lower body 9, respectively, effectively preventing the welded lower body 9 and the middle body 4 from falling off. When the first baffle 10, the second baffle 11, the third baffle 12, and the fourth baffle 13 are extended, they can block the lower body 9. When they are retracted, they are used to remove the lower body 9 and the welded lower body 9 and the middle body 4.

[0020] like Figure 3 As shown, this utility model is used in conjunction with a hot plate 22. The initial position of the hot plate 22 is behind the upper module 100 and the lower module 200. The hot plate 22 can move back and forth. After the hot plate 22 moves forward between the upper module 100 and the lower module 200, the lower module 200 is moved upward by a press (not shown in the figure), and the upper module 100 is moved downward by the press (not shown in the figure). When the welding surfaces touch the hot plate 22, they melt together. After melting, the hot plate 22, the upper module 100, and the lower module 200 are reset. Then, the upper module 100 and the lower module 200 are brought together to weld the product. During welding, the welded middle body 4 and lower body 9 are manually removed and placed on the second upper template 8.

[0021] The thermal management system flow channel plate welding equipment provided by this utility model can realize two welding processes with one set of welding equipment, which can save costs and eliminate the risk of flow channel plate falling off. After the middle body 4 is placed on the first lower template 2, it will be automatically pressed and tightened, making it more convenient to operate.

[0022] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
