Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing technology, and more specifically, to a positioning fixture for lithium battery processing. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, the processing, storage, and use of lithium metal require very high environmental standards. With the development of science and technology, lithium batteries have become the mainstream.

[0003] A positioning fixture for lithium battery processing, disclosed in publication number CN222768227U, includes a worktable. A support column is welded and fixed to the bottom of the worktable. A support sleeve is slidably fitted onto the outer wall of the support column. A connecting plate is welded and fixed to the outer wall of the support sleeve. By rotating an adjusting rod, a fourth lead screw is driven to rotate, which in turn drives the clamping plate to close inward and clamp and fix the lithium battery. Then, a third motor is controlled to work, driving the third lead screw to rotate. A toothed plate connected to the outer edge of the third lead screw drives the toothed plate to move when the third lead screw rotates. At the same time, the toothed plate drives the transmission gear to rotate, which in turn drives the connecting rod to rotate. One end of the connecting rod is fixedly connected to the outer wall of the mounting frame, so that the rotation of the connecting rod drives the fixing device to rotate, and causes the battery clamped and fixed on the inner wall of the clamping plate to flip over, which facilitates processing of different positions of the battery and improves the working efficiency of the device.

[0004] However, based on the working principle proposed in the aforementioned patent, the applicant believes that although the device can improve work efficiency to a certain extent, in actual use, most traditional lithium batteries are cylindrical in shape, and conventional clamps can easily cause squeezing damage to the battery surface when they are clamped and fixed, which has certain defects in use. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a positioning fixture for lithium battery processing, which has the advantages of bottom clamping and small contact area.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for lithium battery processing, comprising a mounting plate, wherein a plurality of evenly distributed seat blocks are fixedly mounted around the upper surface of the mounting plate, a clamping contact is movably mounted on the top of the seat blocks, a control connecting plate is movably connected to one side of the clamping contact, a lifting sleeve is movably connected to the other end of the control connecting plate, a pad is fixedly mounted on the inner side of the lifting sleeve, a buffer spring is fixedly connected to the bottom of the lifting sleeve, a connecting block is fixedly connected to the bottom end of the buffer spring, an output rod is fixedly connected to the bottom of the connecting block, and the output rod is movably mounted on the top end of a hydraulic cylinder.

[0007] As a preferred embodiment of this utility model, a protective frame is fixedly installed on the outer side of the hydraulic cylinder, and side lugs are fixedly installed on both sides of the protective frame.

[0008] As a preferred embodiment of this utility model, the surface of the side ear block is provided with a threaded hole, and a first drive screw is installed on the inner thread of the threaded hole.

[0009] As a preferred embodiment of this utility model, the first drive screw is movably mounted on the inner side of the upper frame, and a first motor is fixedly mounted on one side of the upper frame and at the outer end of the first drive screw.

[0011] As a preferred embodiment of this utility model, a support rod is fixedly installed on the front of the lower frame, and a control panel is fixedly installed on the top of the support rod.

[0012] As a preferred embodiment of this utility model, the surface of the control panel is provided with a display screen, and the bottom of the display screen is provided with operation buttons.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses an mounting plate and evenly distributed seat blocks to enable the clamping contact to move up and down in conjunction with the control plate and lifting sleeve. Combined with the multi-point contact support provided by the pad block and the synergistic effect of the buffer spring and hydraulic cylinder, a bottom clamping structure is formed. The contact area between the clamping contact and the battery surface is small. With the elastic buffering of the buffer spring and the precise output control of the hydraulic cylinder, it can avoid the squeezing damage to the cylindrical lithium battery by traditional clamping plates and ensure clamping stability.

[0015] 2. This utility model protects the hydraulic cylinder with a protective frame. The side lugs and threaded holes work together with the first drive screw and the first motor to achieve the horizontal adjustment function of the upper frame. The second drive screw and the second motor drive the lower frame to complete the vertical position adjustment. The support rod fixes the control panel and integrates the control module with the display screen and operation buttons. The overall structure has multi-directional adjustment capability and intelligent operation advantages. Attached Figure Description

A control connecting plate 4 is movably connected to one side of the clamping contact 3. A lifting sleeve 5 is movably connected to the other end of the control connecting plate 4. A pad block 6 is fixedly mounted on the inner side of the lifting sleeve 5. A buffer spring 7 is fixedly connected to the bottom of the lifting sleeve 5. A connecting block 8 is fixedly connected to the bottom end of the buffer spring 7. An output rod 9 is fixedly connected to the bottom of the connecting block 8. The output rod 9 is movably mounted on the top of the hydraulic cylinder 10.

[0023] The hydraulic cylinder 10 is fixedly mounted with a protective frame 11 on its outer side, and side lugs 12 are fixedly mounted on both sides of the protective frame 11.

[0024] The protective frame 11 protects the hydraulic cylinder 10 from external impacts or contamination; the side lug 12 fixes the first drive screw 14 and allows for position adjustment.

[0025] The side ear block 12 has a threaded hole 13 on its surface, and a first drive screw 14 is installed on the inner thread of the threaded hole 13.

[0026] The threaded hole 13 allows for horizontal displacement in conjunction with the first drive screw 14; the first drive screw 14 also enables the upper frame 15 to be adjusted laterally.

[0027] The first drive screw 14 is movably mounted on the inner side of the upper frame 15, and the first motor 16 is fixedly mounted on one side of the upper frame 15 and at the outer end of the first drive screw 14.

[0028] The upper frame 15 can be used to integrate the first motor 16 and support the horizontal adjustment structure; the first motor 16 can provide rotational power to the first drive screw 14.

[0029] The bottom of the upper frame 15 is threadedly connected to a second drive screw 17, which is movably installed on the inner side of the lower frame 18. A second motor 19 is fixedly installed on the outer side of the lower frame 18 and at the outer end of the second drive screw 17.

[0030] The second drive screw 17 enables the lower frame 18 to be adjusted longitudinally; the lower frame 18 integrates the second motor 19 and supports the longitudinal adjustment structure; the second motor 19 provides rotational power to the second drive screw 17.

[0035] The working principle and usage process of this utility model are as follows: The device drives the output rod 9 through the hydraulic cylinder 10 to push the connecting block 8, so that the buffer spring 7 is elastically compressed in the lifting sleeve 5, which drives the control plate 4 to move the clamping contact 3 towards the center. The clamping contact 3 and the seat block 2 cooperate to clamp the lithium battery at multiple points at the bottom. The pad block 6 enhances the support stability of the lifting sleeve 5. The power output of the hydraulic cylinder 10 is buffered by the buffer spring 7 and transmitted to avoid hard contact damage to the battery surface. The protective frame 11 protects the safe operation of the hydraulic cylinder 10.
