Description

Technical Field

[0001] The invention relates to a universal supporting tool for cutting holes in a battery shell with an uneven shape, and belongs to the technical field of workpiece supporting tooling. Background Art

[0002] With the development of composite material technology, fiber-reinforced materials with advantages such as low specific gravity, high specific strength and modulus, good fatigue resistance and corrosion resistance are the most widely used and used in the composite materials. However, in the process of use, composite materials need to be cut and trimmed in most cases. The processing performance of composite materials is poor, which brings difficulties to cutting. Mechanical cutting often produces phenomena such as drawing, pulling, delamination, ridges and friction burning. The emergence of laser composite material cutting technology breaks through this bottleneck. Laser processing does not require tools, so there is no cutting force. It can perform high-precision cutting on composite materials with certain flexibility. The characteristics of laser cutting are perfectly combined with the performance of composite materials, achieving a wonderful breakthrough in composite material cutting technology. At the same time, positioning support tooling for composite material cutting has also begun to be used.

[0003] Laser cutting of composite battery shells requires that the cutting surfaces of all holes and edges are perpendicular to the main surface of the battery shell. Therefore, the positioning support tooling is required to support the uneven support surface of the battery shell at different heights to keep the main surface of the battery shell in a stable horizontal posture.

[0004] The Chinese utility model patent with application number 202123317742.1 discloses a fixture for a laser cutting machine, including a mounting frame, which is an internal hollow circular structure, and a horizontal slide groove and a longitudinal slide groove are arranged on the mounting frame. A clamp is arranged in the slide groove, and a driving assembly drives the clamp to clamp the cut workpiece. The device clamps the workpiece in the horizontal direction, but cannot be adjusted at will in the height direction. It cannot support and fix the uneven battery shell workpieces of different shapes and cannot be universally used. Summary of the invention

The additional column is installed on the rotating shaft in a scissor-like manner intersecting with the column tube and can rotate around the rotating shaft. A tension spring is provided between the lower end of the lift arm and the lower end of the column tube, and the tension spring applies a downward pulling force to the lower end of the lift arm, so that the upper end of the support arm obtains an upward lift.

[0009] The support arm is a tubular body with a tube hole. An additional core column is inserted from top to bottom in the tube hole of the support arm. The additional core column can be extended and retracted in the tube hole of the support arm.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with embodiments and drawings: Embodiment 1

[0021] like Figure 1 , 2As shown, a universal support tool for cutting holes in uneven battery shells includes a table 1, a longitudinal slide rail 2 and a transverse slide rail 3 provided on the table 1, a slider 4 provided on the longitudinal slide rail 2 and the transverse slide rail 3, and a support column 5 fixed on the slider 2 for supporting the support surface of the battery shell 11, wherein the support column 5 can be extended and retracted up and down and can be fixed at a required height. In this way, no matter how the size of the battery shell and the unevenness of the support surface change, the battery shell can be stably supported by moving the slider 4 and lifting the support column.

[0022] The support column 5 includes a core column 502 and a hollow column tube 501. A threaded hole communicating with the inside and outside is provided on the side wall of one side of the column tube 501. A fastening bolt 503 that can be screwed in or out is provided in the threaded hole. The core column 502 is inserted into the tube hole of the column tube 501 from top to bottom and can be pulled up and down. When the fastening bolt 503 is screwed in, the core column 502 can be pressed and fixed at a set height, and the top of the core column 502 supports the lower bottom surface of the battery shell 11. Embodiment 2

[0023] like Figure 3 As shown in FIG. 5 , the difference from the first embodiment is that an additional column 6 is provided on the column tube 501, the upper section of the additional column 6 is a support arm 601, and the lower section is a lifting arm 602. There is a horizontally arranged rotating shaft 801 outside the column tube 501, and the additional column 6 is installed on the rotating shaft 801 in the form of a scissor-shaped intersection with the column tube 501 and can rotate around the rotating shaft 801. A tension spring 7 is provided between the lower end of the lifting arm 602 and the lower end of the column tube 501, and the tension spring 7 applies a downward pulling force to the lower end of the lifting arm 602, so that the upper end of the support arm 601 obtains an upward lifting force. The advantage of such a setting is that while the support column 5 is used to support the edge of the battery shell 11, the top end of the support arm 601 of the additional column 3 can provide auxiliary support to the center of the bottom of the battery shell 11, so that the bottom of the battery shell 11 obtains a more balanced force, and the support column can be eliminated from the center of the bottom of the battery shell 11. Moreover, since the stretching length of the tension spring 7 can be changed, the height and force of the top of the support arm 601 can be automatically adjusted by the tension spring 7. When in use, it is only necessary to press the center of the bottom of the battery shell 11 on the support arm 601. Therefore, it is more convenient to adjust the height and control the force than to use a dedicated support column 5 at the center of the bottom of the battery shell 11. If a dedicated support column 5 is set at the center of the bottom, it is very difficult to adjust the height of the dedicated support column at the center of the bottom due to interference from other edge support columns.

[0024] like Figure 5 , 6As shown, the support arm 601 is a tubular body with a tube hole, and an additional stem 600 is inserted from top to bottom in the tube hole of the support arm 601. The additional stem 600 can be extended and retracted in the tube hole of the support arm 601. A threaded hole communicating with the inside and outside is provided on the side wall of one side of the support arm 601. A second fastening bolt 603 that can be screwed in or out is provided in the threaded hole. When the second fastening bolt 603 is screwed in, the additional stem 600 can be pressed and fixed at a set height. When used, the top of the stem 502 is used to lift the bottom center of the battery shell 11, and the lifting position can be extended to a farther place.

[0025] Furthermore, the column tube 501 is cylindrical, and the lower end is fixed on the slider 4. A rotating sleeve 8 that can rotate around the column tube 501 is provided on the outer periphery of the column tube 501, and the rotating shaft 801, the tension spring 7 and the additional column 6 are provided on the rotating sleeve 8. In this way, the top end of the core column 502 can rotate around the column tube 501, and combined with its free extension, it can lift any position in the center of the bottom of the battery shell 11.

[0026] like Figure 5 , 7 As shown, the lower end of the spring 7 is fixed to the lower end of the rotating sleeve 8, and a tension adjustment mechanism is provided between the upper end of the tension spring 7 and the lower end of the lifting arm 602, which is used to adjust the tension of the tension spring 7 on the lower end of the lifting arm 602. The tension adjustment mechanism includes an adjustment bolt 10 and a connector 9, one end of the connector 9 is fixedly connected to the tension spring 7, and the other end is provided with an adjustment threaded hole 901. The lower end of the lifting arm 602 is provided with a bolt hole for the adjustment bolt 10 to pass through, and the threaded section of the adjustment bolt 10 passes through the bolt hole at the lower end of the lifting arm 602 and is screwed into the adjustment threaded hole 901 of the connector 9, and the bolt handle of the adjustment bolt 10 is pressed against the lifting arm 602. In this way, the upward lifting force of the additional core column 600 can be adjusted by simply turning the adjustment bolt 10.

[0027] like Figure 5 As shown, the middle part of the additional column 6 is frame-shaped, having a frame cavity 604 that can be sleeved outside the rotating sleeve body 8 and enable the additional column 6 to rotate appropriately. The rotating shaft 801 is welded on both sides of the rotating sleeve body 8, so that the additional column 6 obtains a balanced supporting force from the rotating shaft 801.

[0028] The cross section of the core column 502 and the cross section of the tube hole of the column tube 501 are matched rectangles, and the cross section of the additional core column 600 and the tube hole of the support arm 601 are matched rectangles.

[0029] like Figure 8As shown, both sides of the transverse slide rail 3 and the longitudinal slide rail 2 have T-slots 301 arranged along the length direction, and both sides of the slider 4 have limiting side walls 401, threaded holes are provided on the limiting side walls 401, and fastening bolts three 402 are provided in the threaded holes on the limiting side walls 401, and the ends of the fastening bolts three 402 are conical bodies that fit tightly with the side walls of the T-slots. After the fastening bolts three 402 are tightened into the T-slots 301, the support column 5 and the additional column 6 can be better maintained stable.

[0030] The above embodiments are only used to more clearly describe the present invention and cannot be regarded as limiting the protection scope of the present invention. Any modifications in equivalent forms should be regarded as falling within the protection scope of the present invention.
