The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides a fast-locking battery pole welding clamping fixture, such as Figure 1-4 As shown, a quick-locking battery pole welding clamping fixture includes a placement table 1, a hydraulic push rod 7 and a connecting block 9. Both sides of the top of the placement table 1 are provided with a fixing structure 5, and one side of the fixing structure 5 is provided with a bottom plate 2, the top of the bottom plate 2 is connected to a fixing plate 4, and the top of the fixing plate 4 is connected to a sleeve 6, the inside of the sleeve 6 is provided with an ejection mechanism 3, the top of the sleeve 6 is connected to a support seat 8, and both sides of the inside of the support seat 8 are installed with a hydraulic push rod 7, the top of the hydraulic push rod 7 is connected to a connecting block 9, and one side of the connecting block 9 is connected to a sleeve 10. A pressure plate 12 is fixed to the bottom end of the sleeve plate 10, a positioning platform 14 is connected to the top of the support seat 8, and a pole body 11 is inserted inside the positioning platform 14, and a connecting piece 13 is sleeved on the outer side of the top of the pole body 11. The ejection mechanism 3 includes a first transmission wheel 301, a stepper motor 302, a transmission belt 303, a second transmission wheel 304, a moving block 305, a guide rod 306, a sleeve block 307, a push rod 308 and a screw 309. The stepper motor 302 is installed on the inner wall of the fixed plate 4, and the top of the stepper motor 302 is connected to the first transmission wheel 301.

[0023] The working principle of a quick-locking battery pole welding clamping fixture is as follows: the device is placed on the placement table 1 through the bottom plate 2 and fixed through the fixing structure 5, and powered by an external power supply. By starting the piston of the hydraulic push rod 7 to extend, the connecting block 9 can be pushed to drive the sleeve plate 10 and the pressing plate 12 to move up and away from the surface of the positioning table 14. Then, the pole body 11 can be inserted into the positioning table 14 for positioning and placement, and then the moving connecting piece 13 is aligned and sleeved on the two groups of pole bodies 11 and contacted with the positioning table 14 for placement. By starting the piston of the hydraulic push rod 7 in the support seat 8 to retract, the pole body 11 can be inserted into the positioning table 14 for positioning and placement. By driving the sleeve plate 10 and the pressure plate 12 downward through the connecting block 9, the connecting piece 13 and the pole body 11 can be quickly pressed and locked, and then the laser welding head can weld the connection between the pole body 11 and the pressure plate 12 through the holes opened inside the sleeve plate 10 and the pressure plate 12. When the welding is completed, the pole body 11 and the pressure plate 12 are driven to move up again to leave the surface of the connecting piece 13 by starting the hydraulic push rod 7, and then the ejection mechanism 3 is started to quickly eject the welded pole body 11 and the connecting piece 13, so that the staff can quickly remove it and place the next group.

[0024] It should be noted that, since the existing quick-locking battery pole welding clamping jig generally requires staff to manually remove the welded pole body 11 and connecting piece 13, and since the connecting piece 13 is in contact with the surface of the positioning platform 14, it is inconvenient for staff to pull it. Therefore, in order to solve the problem that the existing quick-locking battery pole welding clamping jig cannot be directly ejected, the present solution adds an ejection mechanism 3, which can eject the pole body 11 from the inside of the positioning platform 14, and move the connecting piece 13 upward and separate it from the positioning platform 14, so that it is convenient for staff to quickly remove it manually.

[0025] In a further embodiment, Figure 1 and Figure 3 As shown, a transmission belt 303 is sleeved on the outer side of the first transmission wheel 301, and a second transmission wheel 304 is inserted inside one side of the transmission belt 303, a screw rod 309 is connected to the top end of the second transmission wheel 304, and a moving block 305 is threadedly connected to the outer side of the screw rod 309, both sides of the moving block 305 are connected to sleeve blocks 307, and a guide rod 306 is inserted inside the sleeve block 307, both sides of the top of the moving block 305 are connected to push rods 308, the bottom of the pressing plate 12 contacts the surface of the connecting piece 13, the bottom of the connecting piece 13 contacts the positioning platform 14, the hydraulic push rod 7 in the support seat 8 extends to the inside of the sleeve shell 6, the push rod 308 passes through the sleeve shell 6 and the support seat 8 and extends to the inside of the positioning platform 14, the two ends of the guide rod 306 are connected to the sleeve shell 6 and the fixing plate 4 by bolts, and the push rod 308 and the pole body 11 are located on the same vertical line.

[0026] In this embodiment, when the welded pole body 11 and the connecting piece 13 need to be taken out, the first transmission wheel 301 is driven to rotate in the positive direction by starting the stepping motor 302, and then the transmission belt 303 drives the second transmission wheel 304 to rotate along with the rotation of the first transmission wheel 301, and then the screw 309 rotates synchronously with the second transmission wheel 304, so that the moving block 305 is engaged with the thread on the screw 309 and drives the two sets of push rods 308 to gradually move upward, so that the pole body 11 welded with the connecting piece 13 in the positioning platform 14 can be removed one by one. The sleeve block 307 slides along the inner wall of the guide rod 306 with the movement of the moving block 305 to guide the moving block 305, so as to ensure the stability of the ejector rod 308. By starting the stepper motor 302 to drive the first transmission wheel 301 to rotate in the opposite direction, the transmission belt 303 drives the screw rod 309 connected to the second transmission wheel 304 to rotate synchronously. Then, the moving block 305 can drive the ejector rod 308 to move down for reset through threaded engagement, so as to facilitate the ejection of the next batch of pole bodies 11.

[0027] In a further embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the fixed structure 5 includes a slider 501, a limit seat 502, an insertion rod 503, a fixing cap 504, a turning handle 505 and a sealing ring 506. The sliders 501 are connected to both sides of the base plate 2. The outer side of the slider 501 is sleeved with a limit seat 502, and the inner side of the limit seat 502 is inserted with an insertion rod 503. The top end of the insertion rod 503 is threadedly connected with the fixing cap 504, and the top end of the sealing ring 506 is connected with the turning handle 505. The outer side of the insertion rod 503 is sleeved with a sealing ring 506. The limit seat 502 is connected to the placement table 1, and the base plate 2 forms a sliding structure with the limit seat 502 through the slider 501.

[0028] In this embodiment, when it is necessary to fix the base plate 2 below the device on the placement table 1, the moving device drives the two groups of sliders 501 to align from the front side and insert into the two groups of limit seats 502 through the base plate 2, and pushes the base plate 2 to drive the sliders 501 to slide along the inner wall of the limit seat 502, so that the insertion rod 503 on the base plate 2 passes through the limit seat 502 and stops, and then the fixing cap 504 is taken and put on the insertion rod 503, so that the turning handle 505 is rotated forward and the fixing cap 504 is engaged with the thread on the insertion rod 503 and gradually fits the limit seat 502 for tightening, so that the insertion rod 503 can be clamped and fixed in the limit seat 502, thereby fixing the base plate 2 on the placement table 1 and ensuring the stability of the device.
