Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, and particularly relates to a tool rest that is convenient to replace. Background Technique

[0002] In the automated production process of lithium batteries, precise and efficient processing equipment is crucial for improving product quality, shortening the production cycle, and reducing production costs. As a key auxiliary device of a numerical control lathe, the numerical control tool rest plays an indispensable role in multiple processes of lithium battery manufacturing, such as the cutting of electrode sheets, the processing of tabs, and the precision drilling of the outer shell.

[0003] Although the existing numerical control tool rest design has achieved automated processing to a certain extent, it is unable to meet the rapid switching requirements of various specifications and shapes of tools in lithium battery production. For example, the patent with the Chinese patent publication number CN214557462U provides a numerical control machine tool tool rest that realizes fine adjustment of the tool position through the cooperation of an adjusting rod and an adjusting seat. However, in actual lithium battery production, this structure is still cumbersome in tool replacement and specification switching and is difficult to meet the requirements of the production line for high efficiency and flexibility.

[0004] Specifically, in the lithium battery production line, due to the different requirements for tool shapes and sizes in different processes, traditional tool rests often require shutdown for complex adjustments when replacing different specifications of tool heads. This not only reduces production efficiency but also may introduce errors due to multiple shutdown adjustments, affecting product quality. In addition, for some precision processing links, such as the precise cutting before tab welding, there are extremely high requirements for the tool replacement speed and positioning accuracy, and traditional tool rests also have obvious deficiencies in this regard.

[0005] Therefore, in view of the special requirements of the lithium battery production line, developing a numerical control tool rest that can quickly replace and flexibly switch different specifications of tool heads is of great significance for improving the production efficiency of lithium batteries and ensuring product quality. The utility model is precisely proposed under this background, aiming to solve the deficiencies in the existing technology through innovative design and provide a more efficient and convenient processing solution for lithium battery production.

The mounting grooves 6 communicate with the tool grooves 4. The insertion plate 7 is installed inside the mounting grooves 6; a limiting insertion hole 51 is provided at the lower end of the tool head 5. One end of the insertion plate 7 is fitted and inserted inside the limiting insertion hole 51. The insertion plate 7 can limit and fix the tool head 5. The size and shape of the cutting part at the upper end of each tool head 5 are different, and the lower ends of each tool head 5 are the same. The limiting insertion holes 51 provided on the tool head 5 are the same; a cover plate 8 is installed on one side of the tool rest mounting plate 3 through a bolt 81. A spring 9 is fixedly installed inside the cover plate 8. One end of the spring 9 is fixedly connected to one end of the insertion plate 7. The insertion plate 7 displaces towards one end of the spring 9, and the insertion plate 7 disengages from the inside of the limiting insertion hole 51. After the tool head 5 is taken out, the spring 9 drives the insertion plate 7 to reset; a plurality of through holes 10 are provided on the tool rest mounting plate 3.

[0051] In summary: The tool rest provided in this embodiment, when applied to the lithium battery production line, greatly improves the convenience of tool replacement and the processing efficiency. The specific usage method is as follows:

[0052] 1. Tool head selection and switching:

[0053] When it is necessary to switch to tool heads of different specifications to adapt to different processes in lithium battery production, first, by turning the screw rod 21, the screw rod 2 is screwed out of the threaded groove 31 of the tool holder mounting plate 3 to release the fixation of the tool holder mounting plate 3.

[0054] Subsequently, by utilizing the cooperation between the rotating rod 12 and the bearing 11, the tool holder mounting plate 3 can be easily rotated to align the required tool head 5 with the processing position.

[0055] Finally, the screw rod 2 is screwed into the threaded groove 31 again, and the tool holder mounting plate 3 is firmly fixed on the mounting seat 1 through threaded connection, completing the rapid switching of the tool head.

[0056] 2. Tool head replacement:

[0057] When a certain tool head 5 needs to be replaced due to wear or damage, first, the connecting rod 71 is pulled through the pull ring 72, and the connecting rod 71 drives the insertion plate 7 to move away from the tool head 5 against the elastic force of the spring 9.

[0058] As the insertion plate 7 displaces, it disengages from the limit insertion hole 51 at the lower end of the tool head 5, and at this time, the old tool head 5 can be easily taken out from the tool groove 4.

[0059] Insert the new tool head 5 into the tool groove 4 and ensure that its limit insertion hole 51 is aligned with the installation groove 6.

[0060] Release the pull ring 72, and the spring 9 automatically rebounds, pushing the insertion plate 7 to re-insert into the limit insertion hole 51 to realize the limit fixation of the new tool head 5, completing the rapid replacement of the tool head.

[0061] As can be seen from the above introduction, the tool holder of the present utility model not only realizes the rapid switching of multiple tool heads of different specifications, but also greatly simplifies the process of tool head replacement, improving the processing efficiency and flexibility of the lithium battery production line. At the same time, due to the adoption of the limit fixation method of the insertion plate 7 and the spring 9, the stability and safety of the tool head during the processing are ensured.
