Description

Technical Field

[0001] This utility model relates to the field of lithium ingot production technology, specifically to an adjustable lithium ingot cutting fixture. Background Technology

[0002] During the lithium ingot production process, the end faces of the lithium ingots formed after casting and cooling are mostly uneven. Therefore, a lithium ingot cutting device is needed to cut off the end portion of the lithium ingot to ensure that the end of the lithium ingot is flat and meets the production requirements of subsequent lithium batteries.

[0003] The currently used lithium ingot cutting device is the lithium ingot head-cutting machine described in Chinese Patent Publication No. CN218362049U. It includes a frame, a linear drive mechanism, a cutting wire, and a lithium ingot placement mechanism. Both the linear drive mechanism and the lithium ingot placement mechanism are mounted on the frame. The cutting wire is connected to the linear drive mechanism and has a cutting ring. The lithium ingot placement mechanism includes a cylindrical structure with an internal space for holding lithium ingots. A cutting slit is formed along the cross-sectional direction of the cylindrical structure. The cutting ring of the cutting wire extends into the cutting slit when the linear drive mechanism is extended. In use, the lithium ingot is placed inside the cylindrical structure, and the cutting wire cuts the end portion of the lithium ingot along the cutting slit, preventing the cutting wire from slipping and improving cutting stability and accuracy. However, this device can only cut lithium ingots of a single specification. To cut lithium ingots of different diameters or lengths, different sized cylindrical structures are required, affecting production efficiency. The weight of the cylindrical structure is generally between 18-22kg, which is quite heavy. Not only is it difficult to replace, but it also requires the pre-manufacturing of various cylindrical structures of different specifications, which wastes manpower and resources and results in high costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an adjustable lithium ingot cutting fixture, including a base, on which a first cylinder, a second cylinder, a linear guide rail, a positioning mechanism and a radial telescopic limiting member are provided. The first cylinder and the second cylinder are arranged horizontally and coaxially and have the same inner diameter. The first cylinder slides along its axial direction with the linear guide rail, and the second cylinder is fixedly installed on the base.

[0009] The positioning mechanism includes a positioning bolt threaded into the threaded through hole. The positioning bolt passes through the threaded through hole and abuts against the linear guide rail, causing the first cylinder to abut against the linear guide rail.

[0010] Furthermore, a drive shaft is rotatably connected to the base. The drive shaft is arranged horizontally and perpendicular to the central axis of the first cylinder. The drive shaft is provided with a handle and a gear. The handle is located at the end away from the first cylinder, and the gear is arranged coaxially with the drive shaft.

[0012] Furthermore, the radial telescopic limiting member includes a radial telescopic portion arranged radially along the first cylinder and a limiting block connected to the radial telescopic portion, the limiting block being located within the cavities of the first cylinder and the second cylinder.

[0013] Furthermore, the radial telescopic part includes a connecting rod and an adjusting screw;

[0014] Both the first cylinder and the second cylinder have horizontally radially arranged mounting through holes on their side walls; the connecting rod passes through the mounting through hole and is axially slidingly engaged with the hole wall of the mounting through hole; one end of the connecting rod is connected to the limiting block, and the other end of the connecting rod is provided with a T-shaped through groove;

[0015] The base is provided with an adjusting block, and the adjusting block is provided with an adjusting screw hole. The adjusting screw hole is a through hole and parallel to the mounting through hole. The adjusting screw is threaded into the adjusting screw hole. The end of the adjusting screw away from the connecting rod is provided with a handle. The other end of the adjusting screw is coaxially provided with a ring plate. The ring plate is located in the T-shaped through groove and is rotatably connected to the connecting rod. The side wall of the T-shaped groove, which is perpendicular to the adjusting screw, limits the axial movement of the ring plate.

[0016] Furthermore, the connecting rod on the first cylinder and the connecting rod inside the second cylinder are connected together by a connecting frame, and the T-shaped through groove is provided on the connecting frame.

[0017] Furthermore, the base is provided with a limiting groove; the connecting frame is provided with a limiting slider, the limiting slider is located in the limiting groove and slides in cooperation with the limiting groove along the axial direction of the connecting rod; the T-shaped through groove is provided on the limiting slider.

[0018] Furthermore, the limiting block is provided with a V-shaped through groove, the opening of which is horizontally oriented toward the axis of the first cylinder; the groove wall of the V-shaped through groove is a limiting surface.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: It provides an adjustable lithium ingot cutting fixture, which is made by setting a first cylinder and a second cylinder with adjustable axial spacing, and setting cutting slits on the first cylinder and the second cylinder respectively.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figure 1-4 As shown, an adjustable lithium ingot cutting fixture includes a base 1, characterized in that: the base 1 is provided with a first cylindrical body 21, a second cylindrical body 22, a linear guide rail 3, a positioning mechanism 4, and a radial telescopic limiting member 5; the first cylindrical body 21 and the second cylindrical body 22 are arranged horizontally and coaxially with the same inner diameter; the first cylindrical body 21 slides along its axial direction with the linear guide rail 3, and the second cylindrical body 22 is fixedly installed on the base 1; a first cutting slit 61 is opened in the cross-sectional direction of the first cylindrical body 21, and a second cutting slit 62 is opened in the cross-sectional direction of the second cylindrical body 22; the positioning mechanism 4 is used to position the first cylindrical body 21 axially; the radial telescopic limiting member 5 is located in the cavity of the first cylindrical body 21 and the cavity of the second cylindrical body 22 and its radial position is adjustable.

[0027] In use, the first cylinder 21 is slidably moved on the linear guide rail 3 to adjust the distance between the first cutting slit 61 on the first cylinder 21 and the second cutting slit 62 on the second cylinder 22, so that the distance L1 between the first cutting slit 61 and the second cutting slit 62 is less than the length L2 of the lithium ingot to be cut. Generally, L2-L1 ≥ 3cm is required. The radial position of the radial telescopic limiting member 5 within the first cylinder 21 and the second cylinder 22 is adjusted to change the distance between the radial telescopic limiting member 5 and the inner wall of the cylinder. The space between the limiting surface of the radial telescopic limiting member 5 and the inner wall of the cylinder is a radial limiting space for accommodating the lithium ingot. The minimum width D1 of the cross-section of the radial limiting space should be slightly larger than the outer diameter D2 of the lithium ingot to be cut so that the lithium ingot to be cut can be placed in the radial limiting space. The difference between D1 and D2 is generally between 0.5cm and 1cm. The cutting wire used in conjunction with this invention enters the first cutting slit 61 and the second cutting slit 62 respectively and protrudes from the other end of the cutting slit. The lithium ingot to be cut is placed in the radial limiting space between the limiting surface and the inner wall of the cylinder. The cutting position of the first end of the lithium ingot to be cut is aligned with the first cutting slit 61 on the first cylinder 21, and the cutting position of the last end of the lithium ingot to be cut is aligned with the second cutting slit 62 on the second cylinder 22. The cutting machine is started to complete the cutting of the lithium ingot. The limiting surface on the radial telescopic limiting member 5 and the cylinder wall radially limit the lithium ingot.

[0028] This invention features a first cylindrical body 21 and a second cylindrical body 22 with adjustable axial spacing, and cutting slits on both bodies. By adjusting the axial position of the first cylindrical body 21, the spacing between the two cutting slits can be changed, allowing the invention to be used for supporting and cutting lithium ingots of different lengths. A radial telescopic limiting member 5 is provided to form a radial limiting space with the inner walls of the first and second cylindrical bodies 21 and 22. The size of this radial limiting space can be changed by adjusting the radial position of the limiting member 5 within the cylindrical body, making the invention suitable for radial limiting of lithium ingots with different outer diameters. This expands the invention's applicability, saves manpower and production costs, and improves production efficiency.

[0029] The base 1 is used to support and install the aforementioned components. It can be a thick steel plate or a concrete base, or a frame structure welded from profiles such as channel steel, I-beams, and steel plates. The first cylinder 21 is used to support and accommodate the head of the lithium ingot, and the second cylinder 22 is used to support and accommodate the tail of the lithium ingot. The first cylinder 21 and the second cylinder 22 can also be a ring plate structure. The linear guide rail 3 is used to ensure the axial movement of the first cylinder 21. The sliding fit between the first cylinder 21 and the linear guide rail 3 allows the distance between the first cylinder 21 and the second cylinder 22 to be adjustable, thereby realizing the adjustment of the distance between the first cutting slit 61 and the second cutting slit 62. The second cylinder 22 and the linear guide rail 3 can be welded to the base 1, or they can be fixedly installed on the base 1 by bolts and pins. To enable operators to quickly and accurately adjust the first cylinder 21 and its first cutting slit 61 to the target position, preferably, the base 1 is provided with a scale 12, the length direction of which is arranged along the axial direction of the first cylinder 21, thereby improving the axial adjustment efficiency of the first cylinder 21.

[0030] The positioning mechanism 4 can be a pin that is simultaneously inserted into the linear guide rail 3 and the first cylinder 21, or a stop block that abuts against the two end faces of the first cylinder 21. Specifically, the lower end of the first cylinder 21 has a sliding support 23, which slides with the linear guide rail 3 along the axial direction of the first cylinder 21; the sliding support 23 has a threaded through hole 41; the positioning mechanism 4 includes a positioning bolt 42 threadedly installed in the threaded through hole 41, which passes through the threaded through hole 41 and abuts against the linear guide rail 3, so that the first cylinder 21 abuts against the linear guide rail 3, thereby preventing the first cylinder 21 from sliding relative to the linear guide rail 3, and realizing the axial positioning of the first cylinder 21 and the first cutting slit 61 on it. When adjusting the axial position of the first cylinder 21, it is only necessary to rotate the positioning bolt 42 to disengage it from the linear guide rail 3 and then push or pull the first cylinder 21. The structure is simple, the operation is convenient, and the cost is saved.

[0031] The first cylinder 21 can be directly pulled or pushed manually, requiring the operator's arm to extend into the device, which is inconvenient and dangerous. Specifically, a drive shaft 71 is rotatably connected to the base 1. The drive shaft 71 is arranged horizontally and perpendicular to the central axis of the first cylinder 21. The drive shaft 71 is equipped with a handle 72 and a gear 73. The handle 72 is located at the end furthest from the first cylinder 21, and the gear 73 is coaxially arranged with the drive shaft 71. A rack 74 is fixedly mounted on the sliding support 23, arranged axially along the first cylinder 21, and meshes with the gear 73. Rotating the handle 72 causes the drive shaft 71 to rotate, which in turn drives the rack 74 to move axially along the first cylinder 21. The rack 74 then drives the sliding support 23 and the first cylinder 21 to move axially. Since the handle 72 is located outside the clamp, the operator can move the first cylinder 21 axially without extending their arm into the device, facilitating operation and ensuring safety. The drive shaft 71 can also be driven by a motor, saving manpower.

[0032] The radial telescopic limiting member 5 cooperates with the inner walls of the first cylinder 21 and the second cylinder 22 respectively to adjust the radial limiting space size. The radial telescopic limiting member 5 has various structural forms; it can be a push rod structure or a structure assembled from a telescopic rod and a limiting plate. Specifically, the radial telescopic limiting member 5 includes a radial telescopic part arranged radially along the first cylinder 21 and a limiting block 52 connected to the radial telescopic part. The limiting block 52 is located within the cavities of the first cylinder 21 and the second cylinder 22. The radial telescopic part drives the limiting block 52 to synchronously telescopically extend and retract, adjusting the size of the radial limiting space.

[0033] The radial telescopic part is used to drive the radial movement of the limiting block 52. The radial telescopic part can be a lead screw structure, or an automatic push rod structure such as a cylinder or hydraulic cylinder. Specifically, the radial telescopic part includes a connecting rod 53 and an adjusting screw 54; both the first cylinder 21 and the second cylinder 22 have horizontally radially arranged mounting through holes on their side walls; the connecting rod 53 passes through the mounting through hole and is axially slidingly engaged with the hole wall of the mounting through hole; one end of the connecting rod 53 is connected to the limiting block 52, and the other end of the connecting rod 53 is provided with a T-shaped through groove 57; the base 1 is provided with an adjusting block 11, and the adjusting block 11 is provided with an adjusting screw hole, which is a through hole and parallel to the mounting through hole; the adjusting screw 54 is threaded into the adjusting screw hole, and the end of the adjusting screw 54 away from the connecting rod 53 is provided with a handle 55, and the other end of the adjusting screw 54 is coaxially provided with an annular plate 56, which is located in the T-shaped through groove 57 and rotatably connected to the connecting rod 53, and the side wall of the T-shaped through groove 57 perpendicular to the adjusting screw 54 axially limits the annular plate 56. Rotating the handle 55 causes the adjusting screw 54 to rotate and move axially. The adjusting screw 54 drives the ring plate 56 to rotate within the T-shaped groove 57. The ring plate 56 then drives the connecting rod 53 to move axially, thereby adjusting the radial position of the limiting block 52 and improving the radial adjustment accuracy of the connecting rod 53 and the limiting block 52. To ensure smooth sliding of the connecting rod 53 within the adjusting screw hole, preferably, a linear bearing is provided within the adjusting screw hole, and the connecting rod 53 slides axially with the shaft hole of the linear bearing.

[0034] The limiting block 52 in the first cylinder 21 and the limiting block 52 in the second cylinder 22 can be the same or independent of each other. The connecting rod 53 on the first cylinder 21 and the connecting rod 53 in the second cylinder 22 can be connected to the adjusting screw 54, but this structure easily leads to different extension and retraction amounts of the connecting rods 53 on the two cylinders, causing the limiting block 52 in the first cylinder 21 and the limiting block 52 in the second cylinder 22 to be out of parallel horizontal lines, resulting in tilting of the lithium ingot inside the cylinder and affecting cutting accuracy. As a further preferred embodiment, the connecting rod 53 on the first cylinder 21 and the connecting rod 53 in the second cylinder 22 are connected together by a connecting frame 58, and the T-shaped through slot 57 is provided on the connecting frame 58. By rotating the adjusting screw 54, the limiting block 52 in the first cylinder 21 and the limiting block 52 in the second cylinder 22 can move synchronously, ensuring the lithium ingot is arranged horizontally and improving the accuracy of lithium ingot cutting. In addition, this structure reduces the number of times operators need to adjust the limiting blocks 52, reducing the labor intensity of operators and improving work efficiency.

[0035] As a further preferred embodiment, the base 1 is provided with a limiting groove 13; the connecting frame 58 is provided with a limiting slider 59, the limiting slider 59 is located in the limiting groove 13 and slides in cooperation with the limiting groove 13 along the axial direction of the connecting rod 53; the T-shaped through groove 57 is provided on the limiting slider 59, further ensuring that the connecting frame 58 and the connecting rod 53 move horizontally and radially along the cylinder.

[0036] The limiting block 52 can be a rod-shaped structure, a plate-shaped structure, or a combination of other structures. The limiting surface on the limiting block 52 can be a plane or a curved surface. Specifically, the limiting block 52 is provided with a V-shaped through groove, the opening of which is horizontally oriented towards the axis of the first cylindrical body 21; the groove wall of the V-shaped through groove is the limiting surface. When using the limiting block 52 with this structure to limit lithium ingots, the deviation between the limiting heights of lithium ingots with different outer diameters can be reduced, thereby improving cutting accuracy.

[0037] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
