Description

Technical Field

[0001] This utility model relates to the technical field of welding deformation correction devices, and in particular to a correction device for brazing deformation of liquid cooling plates for harmonica tube batteries. Background Technology

[0002] Combination Figure 1 and Figure 2 The diagram shows a harmonica-tube type battery liquid cooling plate. The battery liquid cooling plate 100 includes two long current collectors 101 and multiple short current collectors 102. Two harmonica tubes 103 are welded to each short current collector 102. One harmonica tube 103, with its end away from the short current collector 102, is welded to one of the long current collectors 101, and the other harmonica tube 103, with its end away from the short current collector 102, is welded to the other long current collector 101. A water inlet pipe 104 is welded to one of the long current collectors 101, and a water outlet pipe 105 is welded to the other long current collector 101. Caps 106 are welded to both ends of the long current collectors 101 and the short current collectors 102, respectively. A mounting bracket 107 is welded to the top surface of each short current collector 102.

[0003] Combination Figure 3 As shown, the welding requirements for the harmonica tube 103 and the short manifold 102 are as follows: the end of the harmonica tube 103 is inserted into the inner cavity from the side wall of the short manifold 102 and welded, and the upper and lower planes of the harmonica tube 103 are parallel to the upper and lower planes of the short manifold 102.

[0004] However, after actual welding, the brazed joint between the harmonica tube 103 and the short manifold 102 is prone to collapse defects, that is, the short manifold 102 tilts upward or downward relative to the harmonica tube 103, specifically as follows: Figure 4 As shown. Therefore, the short collector tube 102 needs to be corrected so that the upper and lower planes of the harmonica tube 103 and the upper and lower planes of the short collector tube 102 are parallel to each other.

[0038] Combination Figures 5 to 9The image shows a specific embodiment of a correction device for brazing deformation of a harmonica tube battery liquid cooling plate provided by this utility model. The correction device includes:

[0039] Harmonica tube holder 200 is used to hold two harmonica tubes 103;

[0040] The manifold alignment clamp 300 is used to clamp the short manifold 102 that is welded to the two harmonica tubes 103;

[0041] The harmonica tube holder 200 includes a handrail 201; the manifold correction clamp 300 includes a handle 301.

[0042] The harmonica tube holder 200 further includes an upper clamping plate 202, a lower clamping plate 203, a threaded pull rod 204, and a locking cam 205; the handrail frame 201 has an inverted U-shaped structure and is welded to the top surface of the upper clamping plate 202; a T-shaped slot 203a is provided in the middle of the lower clamping plate 203; the threaded pull rod 204 is a T-bolt, the T-shaped head of the threaded pull rod 204 is engaged in the T-shaped slot 203a, and the upper section of the threaded pull rod 204 passes through the central hole of the upper clamping plate 202 and is screwed with a threaded sleeve 206; the lower part of the locking cam 205 is provided with a U-shaped opening 205a, and the two side plates of the U-shaped opening 205a are respectively connected to the threaded sleeve 206 through pins 207.

[0043] To prevent the harmonica tube holder 200 from pinching the harmonica tube 103, an upper pad 208 is bonded to the lower surface of the upper clamping plate 202; a lower pad 209 is bonded to the upper surface of the lower clamping plate 203; both the upper pad 208 and the lower pad 209 are silicone rubber sheets.

[0044] To prevent the threaded sleeve 206 from loosening, a flange nut 210 is screwed onto the upper end of the threaded tie rod 204, and the flange nut 210 abuts against the top of the threaded sleeve 206.

[0045] Combination Figure 7 and Figure 8 As shown, the T-shaped slot 203a is open on the left and closed on the right. When clamping the harmonica tube 103, the harmonica tube holder 200 first places the lower clamping plate 203 with the lower pad 209 attached below the harmonica tube 103, with the opening of the T-shaped slot 203a facing away from the short positive current collector 102 to be calibrated. Then, the assembly equipped with the threaded pull rod 204, locking cam 205, and threaded sleeve 206 is placed on the upper surface of the harmonica tube 103, and then the assembly is moved towards the short positive current collector 102 to be calibrated, so that the T-shaped head of the threaded pull rod 204 engages with the opening of the T-shaped slot 203a. Then, the locking cam 205 is rotated to clamp the harmonica tube 103.

[0046] Combination Figure 8 As shown, a pair of cutting planes 204a are provided at the top of the threaded tie rod 204. When it is necessary to clamp harmonica tubes 103 of different thicknesses, a wrench can be used to clamp them on the cutting planes 204a. Then, another wrench is used to loosen the flange nut 210. At this time, the threaded sleeve 206 can be rotated to adjust the distance between the threaded sleeve 206 and the T-head of the threaded tie rod 204. After the adjustment is completed, the flange nut 210 is tightened.

[0047] In this embodiment, the manifold correction clamp 300 further includes a clamp base 302 and two clamping claws 303; the clamp base 302 includes a clamping base plate 302a and a vertical plate 302b integrally formed on the top surface of the clamping base plate 302a; the clamping claws 303 are mounted on the vertical plate 302b; the clamp handle 301 is welded to the right side of the vertical plate 302b. When clamping the short manifold 102, the short manifold 102 is clamped between the clamping base plate 302a and the clamping claws 303.

[0048] Furthermore, to make the manifold straightening clamp 300 suitable for clamping short manifolds 102 of different lengths, two vertical T-shaped grooves 302c are provided on the left side of the vertical plate 302b; the clamp claws 303 are installed in the T-shaped grooves 302c; a waist-shaped hole 302d is provided on the vertical plate 302b, and a fastening screw 304 is installed in the waist-shaped hole 302d; the left end of the fastening screw 304 is screwed onto the clamp claw 303. With the above structure, since the clamp claws 303 slide in the T-shaped grooves 302c, when it is necessary to adjust the distance between the clamping base plate 302a and the clamp claws 303, the fastening screw 304 is loosened, the clamp claws 303 are slid up and down, and after adjustment, the fastening screw 304 is tightened.

[0049] A clearance groove 302e is formed at the center of the vertical plate 302b; the left half of the clamp handle 301 is configured as a U-shaped rod and the right half as a straight rod; and the opening of the U-shaped rod is directly opposite the clearance groove 302e. The clearance groove 302e and the opening of the U-shaped rod provide clearance for the mounting bracket 107 on the battery liquid cooling plate 100, thus avoiding interference.

[0050] Combination Figures 10 to 13 As shown, the working principle of the calibration device provided in this embodiment is as follows:

[0051] When correcting a short manifold 102 that has tilted after welding, a harmonica tube holder 200 is used to clamp the two harmonica tubes 103 corresponding to the tilted short manifold 102. At the same time, a manifold correction pliers 300 is used to clamp the short manifold 102. The operator holds one hand on the handrail 201 and keeps it still, while holding the pliers handle 301 with the other hand. If the short manifold 102 tilts upward, the pliers handle 301 is pressed down clockwise; if the short manifold 102 tilts downward, the pliers handle 301 is pressed up counterclockwise. This corrects the short manifold 102.

[0052] This calibration device is applicable to battery liquid cooling plate 100 products of the same type. It can adapt to harmonica tubes 103 of different thicknesses and short current collectors 102 of different thicknesses by simply adjusting the clamping distance of the harmonica tube holder 200 and the current collector calibration clamp 300, and has strong versatility.

[0053] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
