Description

Technical Field

[0001] This utility model relates to the technical field of battery tray processing equipment, and in particular to a fixing device for stirring welding of liquid-cooled plates for battery trays. Background Technology

[0002] Friction stir welding refers to the use of heat generated by the friction between a high-speed rotating welding tool and the workpiece to locally melt the materials to be welded. As the welding tool moves forward along the welding interface, the plasticized material flows from the front to the rear of the welding tool under the action of the rotational friction force of the welding tool, and forms a dense solid phase weld under the extrusion of the welding tool.

[0003] Currently, during the production and processing of battery trays, the surface of the components needs to be stirred and welded, which makes the battery trays prone to displacement. During the unloading process, the steel plate pressing on the top of the battery tray needs to be removed manually before unloading, which greatly reduces the labor intensity of workers.

Detailed Implementation

[0025] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0026] like Figures 1-6 As shown, the fixing device for stirring welding of liquid-cooled battery trays according to this utility model includes a base plate 1, a support frame 2, a fixing mechanism 3, a mounting plate 4, a moving mechanism 5, and a steel plate 10.

[0027] A support frame 2 is provided above the middle of the base plate 1; a magnetic suction device for fixing the bottom of the battery tray is provided above the support frame 2; a number of fixing mechanisms 3 for fixing the workpiece to be processed are provided on the base plate 1; mounting plates 4 extend from both sides of the base plate 1; a moving mechanism 5 for pulling the steel plate 10 is provided on the mounting plate 4; and a lifting handle is provided on the steel plate 10.

[0028] The fixing mechanism 3 includes a first drive cylinder 31, a micro motor 32, a rotating shaft 33, a pressing swing arm 34, an L-shaped fixing plate 35, a second drive cylinder 36, and a suction cup 37.

[0029] A plurality of first driving cylinders 31 are provided above the base plate 1; the connecting rod of the first driving cylinder 31 is connected to the micro motor 32; the output end of the micro motor 32 is connected to the rotating shaft 33; the clamping swing arm 34 is sleeved on the rotating shaft 33; an L-shaped fixing plate 35 is provided on the base plate 1; a second driving cylinder 36 is installed on the L-shaped fixing plate 35; the connecting rod of the second driving cylinder 36 is connected to the suction cup 37; the suction cup 37 is connected to an external vacuum device.

[0030] The moving mechanism 5 includes a slide 51, a screw 52, ​​a rotary motor 53, a moving block 54, an electric push rod 55, and a pull block 56;

[0031] The bottom of the mounting plate 4 is slidably connected to the slide groove 51; the screw 52 is rotatably installed inside the slide groove 51; the outer end of the slide groove 51 is provided with the rotary motor 53 that drives the screw 52 to rotate; the screw 52 is attached with two opposite thread lines; and the moving block 54 is threadedly connected to the different thread lines; the bottom of the moving block 54 is provided with the electric push rod 55; the connecting end of the electric push rod 55 is connected to an L-shaped pull block 56.

[0032] The bottom of the mounting plate 4 is provided with a sliding block 6; a T-shaped groove 7 is provided in the sliding block 6; a T-shaped block 8 is slidably connected to the T-shaped groove 7; the bottom of the T-shaped block 8 is fixedly connected to the upper end of the sliding groove 51; a third driving cylinder 9 is provided at the outer end of the mounting plate 4; the connecting end of the third driving cylinder 9 is connected to the T-shaped block 8.

[0033] Working principle: The battery tray is placed above the support frame 2. When the stir welding head is welding the battery tray, it needs to weld a ring around the outer edge of the battery tray parts. At this time, the magnetic attraction device on the support frame 2 is activated to magnetically attract the bottom of the battery tray, ensuring the stability of the welding process.

[0034] When clamping the workpiece, the steel plate 10 can be placed on the surface of the workpiece to clamp the middle part of the battery tray. Then, the first drive cylinder 31 is activated again to drive the clamping swing arm 34 to descend. Then, the micro motor 32 causes the clamping swing arm 34 to rotate, thereby achieving stable clamping of the battery tray surface. At the same time, the second drive cylinder 36 is activated, causing the cylinder connecting rod to drive the suction cup 37 to fix the side of the battery tray, further improving the stability of the device during processing.

[0035] After fixing, an external stirring rod is used to perform stir welding on the surface of the workpiece. Since this is not the main inventive point of this utility model and stir welding is prior art, it is not described in detail. After the stir welding is completed, the third drive cylinder 9 is turned on, so that the cylinder pushes the slide 51 to the position above the handle of the steel plate 10. The electric push rod 55 is turned on, so that the electric push rod 55 drives the pull block 56 to abut against the surface of the steel plate 10. The rotating motor 53 is turned on, so that the motor rotates and drives the screw 52 to rotate. Then, the two moving blocks 54 drive the pull block 56 away, so that the pull block 56 extends into the position of the two handles of the steel plate 10. Then, the electric push rod 55 drives the steel plate 10 to pull upward, which improves the work efficiency.
