Description

Technical Field

[0001] This utility model relates to the field of lifting fixture technology, and in particular to a lifting fixture for processing automotive lithium batteries. Background Technology

[0002] With the booming development of the new energy vehicle industry, the production and processing scale of automotive lithium batteries, as a core component, is also constantly expanding. In the production, manufacturing, and subsequent maintenance and testing processes of automotive lithium batteries, it is often necessary to lift and move the lithium batteries to different processing stations or to perform corresponding treatments.

[0003] Traditional lifting clamps have several shortcomings when applied to automotive lithium batteries. Firstly, most conventional lifting clamps rely solely on simple clamping mechanisms for contact and fixation with the lithium battery, such as using simple claw structures to hold the sides or a specific area of ​​the battery. This contact method results in a small force-bearing area, leading to excessive localized pressure during lifting. Due to the unique structure of lithium batteries, this excessive localized pressure can easily damage them, affecting battery performance and safety.

[0004] On the other hand, existing lifting fixtures for automotive lithium batteries of different sizes and specifications have poor versatility and are difficult to adapt flexibly to various sizes of lithium batteries. This often requires preparing multiple sizes of fixtures or making cumbersome adjustments, which undoubtedly reduces processing efficiency and increases operational complexity and labor costs. Furthermore, the addition of this sampling step significantly increases the cost of use.

[0005] Moreover, when lithium batteries need to be moved to different processing points, traditional fixtures are not easy to move, making it difficult to easily move them on flat ground, which brings many inconveniences to actual production operations. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a lifting fixture for processing automotive lithium batteries, which has the advantages of high versatility, no crushing damage, and easy mobility, thus solving some of the problems mentioned in the background art.

[0007] This utility model provides the following technical solution: a lifting fixture for processing automotive lithium batteries, comprising a lifting electromagnet and a processing table. Sliding clamps are installed on both the left and right sides of the processing table. A fixing component is fixedly installed at the upper middle of each clamp, and an iron disc is fixedly installed at the upper middle of each fixing component. The iron disc is magnetically connected to the lifting electromagnet. A bidirectional screw is rotatably installed on the upper end of the processing table near both the front and rear sides. The front and rear ends of the two sets of clamps are threaded onto the outer side of the bidirectional screw and are symmetrical to each other. A driven bevel gear is fixedly sleeved on the right end of each bidirectional screw. A transmission rod is rotatably installed on the upper end of the processing table near the right side. A main bevel gear is fixedly sleeved on the outer side of the transmission rod near both the front and rear sides, and the main bevel gear and the driven bevel gear are meshed together.

[0008] Furthermore, bearing seats are fixedly installed on the upper end of the clamping plate near the front and rear sides, and a double-acting screw is rotatably installed between the bearing seats. Two sets of symmetrical right-angle baffles are slidably installed on the clamping plate, and threaded grooves are opened on the upper end of the right-angle baffles. The double-acting screws are threaded through and threaded into the inside of the threaded grooves.

[0009] Furthermore, each of the right-angle baffles has a through-hole and threaded fastening screw at its upper end, and each of the fastening screws has a fixed abutment at its lower end. The structure is simple and can be adjusted according to different conditions on the solar panel.

[0010] Furthermore, each clamping plate is provided with a movable groove in the middle position, and each right-angle baffle is provided with a limiting block in the middle position. The limiting blocks are all connected through and slidably inside the movable groove. Each clamping plate is provided with a sliding groove near the lower side. The sliding groove is slidably sleeved on the outside of the processing table. The sliding of the limiting blocks inside the movable groove ensures the rationality of the structural design and improves the structural strength of the right-angle baffle. The sliding sleeve of the sliding groove on the outside of the processing table can greatly improve the uniformity of the force on the clamping plate during hoisting and distribute the load of the bidirectional screw.

[0011] Furthermore, casters are fixedly installed at the four corners of the lower end of the processing table, which can also be used to move the automotive lithium battery to the vicinity of the hoisting equipment and make adjustments by directly pushing this device, making it more flexible and convenient to use.

[0012] Furthermore, a knob is fixedly installed at the front end of the transmission rod, and a knob is fixedly installed at the front end of the bidirectional screw. The knobs are convenient for the operator to rotate and adjust the force.

[0013] The advantages of this utility model are as follows:

[0014] 1. The lifting fixture for processing automotive lithium batteries of this utility model, through its ingeniously designed transmission mechanism, including a knob, transmission rod, main bevel gear, driven bevel gear, and bidirectional screw, achieves omnidirectional positioning and fixing of automotive lithium batteries in the left-right, up-down, and four-corner directions. This design not only improves the versatility of the fixture, making it applicable to automotive lithium batteries of different sizes, but also effectively avoids damage to lithium batteries caused by traditional fixtures due to small force-bearing area and high local pressure through omnidirectional support and positioning. In addition, the omnidirectional support of the bottom of the lithium battery by the processing table ensures uniform force distribution, further improving the protective performance of the fixture.

[0015] 2. On the one hand, the clamp uses the attraction between the lifting electromagnet and the iron plate on the fixing part to lift the automotive lithium battery based on the electromagnetic principle. The operation is simple and convenient and will not cause squeezing damage to the battery panel. On the other hand, after the battery panel is fixed in place, it is convenient for workers to carry out processing operations directly. With the help of the universal wheels designed at the four corners of the lower end of the processing table, it can be easily pushed on flat ground to achieve mobile operation, which is convenient to transport to the next processing point, effectively improving the overall processing efficiency and optimizing the entire production process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3A lifting fixture for processing automotive lithium batteries includes a lifting electromagnet 1 and a processing table 2. Sliding clamps 3 are installed on both the left and right sides of the processing table 2. A fixing member 4 is fixedly installed at the middle of the upper end of each clamp 3. An iron plate 5 is fixedly installed at the middle of the upper end of each fixing member 4. The iron plate 5 is magnetically connected to the lifting electromagnet 1. A double-acting screw 6 is rotatably installed on the upper end of the processing table 2 near both the front and rear sides. The front and rear ends of the two sets of clamps 3 are threaded onto the outside of the double-acting screw 6 and are symmetrical to each other. A driven bevel gear 7 is fixedly sleeved on the right end of each double-acting screw 6. A transmission rod 8 is rotatably installed on the upper end of the processing table 2 near the right side. A main bevel gear 9 is fixedly sleeved on the outside of the transmission rod 8 near both the front and rear sides. The main bevel gear 9 and the driven bevel gear 7 are meshed and connected. The mechanism is activated by rotating the screw. Button 19 can drive the transmission rod 8 to rotate the main bevel gear 9, which in turn drives the driven bevel gear 7, which in turn drives the bidirectional screw 6, which in turn drives the two sets of clamping plates 3 to move symmetrically. This allows the clamping plates 3 to abut against the left and right ends of the automotive lithium battery. First, the upper end of the lifting electromagnet 1 is connected and fixed to the lifting equipment such as an electromagnetic crane via a hook. After the automotive lithium battery is fixed in place, the electromagnetic crane is used to bring the lifting electromagnet 1 into contact with the iron plate 5 on the fixing part 4. By energizing the lifting electromagnet 1, the electromagnetic principle is used to firmly attract the iron plate 5, thus achieving the lifting of the automotive lithium battery. This method is simple and convenient, and will not cause squeezing damage to the battery plate, ensuring the integrity of this technical solution.

[0022] Please see Figure 3Bearing seats 10 are fixedly installed on the upper end of the clamping plate 3 near the front and rear sides. Two bidirectional screws 11 are rotatably installed between the bearing seats 10. Two sets of symmetrical right-angle baffles 12 are slidably installed on the clamping plate 3. The upper end of each right-angle baffle 12 has a threaded groove. The bidirectional screws 11 pass through and are threaded into the threaded groove. Fastening screws 13 pass through and are threaded into the upper end of each right-angle baffle 12. A stop plate 14 is fixedly connected to the lower end of each fastening screw 13. At the middle position of the clamping plate 3... A movable groove 15 is provided, and a limit block 16 is provided at the middle of each right-angle baffle 12. The limit block 16 passes through and is slidably connected inside the movable groove 15. A sliding groove 17 is provided on the clamping plate 3 near the lower side. The sliding groove 17 is slidably sleeved on the outer side of the processing table 2. By rotating the knob 19, the transmission rod 8 can drive the main bevel gear 9 to rotate. The rotation of the main bevel gear 9 drives the driven bevel gear 7 to rotate. The rotation of the driven bevel gear 7 drives the double-acting screw 6 to rotate. The rotation of the double-acting screw 6 can... The device drives the two sets of clamping plates 3 to move symmetrically, allowing the clamping plates 3 to abut against the left and right ends of the automotive lithium battery. By rotating the knob 20, the bidirectional screw 11 is rotated, which in turn drives the two sets of right-angle baffles 12 to move symmetrically, allowing the right-angle baffles 12 to abut against the four corners of the automotive lithium battery. Finally, by rotating the fastening screw 13, the abutment 14 is made to fit against the upper end of the automotive lithium battery, thus avoiding vibration caused by mechanical structure shaking during hoisting and achieving vertical limitation. This completes the limitation and fixation of the automotive lithium battery, applicable to automotive lithium batteries of different sizes, greatly improving the versatility and flexibility of the device. At the same time, the device can provide all-round support for the bottom of the automotive lithium battery through the processing platform 2, with uniform force distribution, making it safer and more reasonable. Compared with general hoisting clamps, it avoids the situation where the contact between the clamping mechanism and the automotive lithium battery is only through the clamping mechanism, resulting in a small force area and high local pressure, which can easily damage the automotive lithium battery.

[0023] Please see Figure 1 The processing table 2 is equipped with casters 18 at the four corners of its lower end, and knobs 19 are fixedly installed at the front end of the transmission rod 8. Knobs 20 are fixedly installed at the front end of the bidirectional screw 11. After the solar panel is fixed in place by the above operation, it is convenient for the staff to carry out the processing operation. The casters 18 designed at the four corners of the lower end of the processing table 2 can be easily pushed by the staff to move the work on the ground, making it convenient to transport to the next processing point and greatly improving the processing efficiency.

[0024] Working principle: In use, rotating knob 19 causes the transmission rod 8 to rotate the main bevel gear 9, which in turn rotates the driven bevel gear 7, which in turn rotates the bidirectional screw 6. The rotation of the bidirectional screw 6 causes the two sets of clamping plates 3 to move symmetrically, thus placing the clamping plates 3 against the left and right ends of the automotive lithium battery. Rotating knob 20 causes the bidirectional screw 11 to rotate, which in turn moves the two sets of right-angle baffles 12 symmetrically, placing the right-angle baffles 12 against the four corners of the automotive lithium battery. Finally, rotating the fastening screw 13 causes the abutment 14 to adhere to the automotive lithium battery. Furthermore, at the upper end, the upper end of the lifting electromagnet 1 is first connected and fixed to the lifting equipment such as the electromagnetic crane via a hook. After the limit and fixation of the automotive lithium battery is completed, the lifting electromagnet 1 is brought into contact with the iron plate 5 on the fixing part 4 by operating the electromagnetic crane. Then, by energizing the lifting electromagnet 1, the electromagnetic principle is used to make it firmly attract the iron plate 5, thereby finally realizing the lifting of the automotive lithium battery. In addition, after the battery plate is limited and fixed by the above operation, it is convenient for the staff to carry out processing operations. The universal wheels 18 designed at the four corners of the lower end of the processing table 2 can be easily pushed by the staff for moving operations on flat ground.
