[0027] The present invention will be further described below with reference to the accompanying drawings: Example

[0028] Reference Figure 1-8 A three-in-one tooling for a carbon fiber rear subframe includes a base 1 and a tooling bracket 6, wherein: four tooling brackets 6 are provided so that the four corners of the carbon fiber rear subframe 11 can be positioned, supported and fixed by the tooling bracket 6, and a distance adjuster is provided at the bottom of each tooling bracket 6 so that the distance between the four tooling brackets 6 can be adjusted by the distance adjuster to meet the support and fixation of carbon fiber rear subframes of various specifications. Each tooling bracket 6 is slidably installed on the base 1 through the distance adjuster so that the tooling bracket 6 equipped with the carbon fiber rear subframe 11 can be placed on the corresponding testing table through the base 1, and a clamping device for clamping the carbon fiber rear subframe 11 is fixedly installed on the outer side of the top end of each tooling bracket 6. The setting of the clamping device is not only convenient and flexible, but also compact and light in structure, which can reduce the overall weight.

[0029] The top of the tooling bracket 6 is provided with a positioning cavity 61 and a notch 62. Through the setting of the positioning cavity 61, when the rubber bushing is pressed into the four corners of the carbon fiber rear subframe 11, the rubber bushing can be positioned to prevent the rubber bushing from being over-pressed. The notch 62 is connected to the positioning cavity 61, so that the four corners of the carbon fiber rear subframe 11 enter the corresponding positioning cavity 61 through the corresponding notch 62, thereby positioning and supporting the carbon fiber rear subframe 11. The notch 62 is toward the center of the base 1; the tooling bracket 6 is provided with a positioning cavity 61. An oil passage 64 is provided so as to store the required hydraulic oil in the oil passage 64, and one end of the oil passage 64 is located on the side below and outside the positioning cavity 61, and the other end of the oil passage 64 is communicated with the positioning cavity 61; an outward-expanding rubber locking strip 63 for locking the carbon fiber rear sub-frame 11 is fixedly installed on the inner surface of the connection between the positioning cavity 61 and the oil passage 64, so that the outward-expanding rubber locking strip 63 is pressurized by the hydraulic oil, so that the outward-expanding rubber locking strip 63 expands and squeezes the carbon fiber rear sub-frame 11, thereby clamping the carbon fiber rear sub-frame 11.

[0030] The oil channel 64 is filled with hydraulic oil so that the required clamping energy can be provided by the hydraulic oil, and the oil channel 64 is located in the port on the outer side below the positioning cavity 61 and is threadedly installed with an adjusting screw 7. By setting the adjusting screw 7, the hydraulic oil in the oil channel 64 can be squeezed or the pressure of the hydraulic oil in the oil channel 64 can be released, which facilitates the disassembly and assembly of the carbon fiber rear subframe 11. An oil seal 8 is provided between the adjusting screw 7 and the oil channel 64 to prevent leakage of the hydraulic oil.

[0031] The distance adjuster includes a rectangular support frame 3, a screw rod 4 and a rotating cap 5, and the rectangular support frame 3 is fixedly installed at the angle of the base 1. The screw rod 4 is rotatably installed in the rectangular support frame 3 so that the screw rod 4 is supported by the rectangular support frame 3 to ensure the stability and smoothness of the screw rod 4 during rotation; one end of the screw rod 4 is rotated out from the corresponding angle of the base 1, and the end of the screw rod 4 passing through the base 1 is fixedly installed with a rotating cap 5, so that the operator can rotate the screw rod 4 forward and backward through the rotating cap 5, and drive the tooling bracket 6 to move under the forward and reverse rotation of the screw rod 4, thereby adjusting the distance between each tooling bracket 6; the screw rod 4 is meshed and connected with the tooling bracket 6, and the tooling bracket 6 is slidably connected with the rectangular support frame 3.

[0032] The bottom of the tooling bracket 6 is detachably fixedly installed with a connecting seat 9 so that the tooling bracket 6 can be disassembled and replaced separately, and the bottom of the connecting seat 9 is fixedly installed with an internal threaded sleeve 10; the internal threaded sleeve 10 is sleeved on the corresponding screw rod 4, and the internal threaded sleeve 10 is meshed and connected with the corresponding screw rod 4, and power is transmitted through the setting of the internal threaded sleeve 10 and the screw rod 4; the connecting seat 9 and the internal threaded sleeve 10 are slidably connected to the corresponding rectangular support frame 3, and the connecting seat 9 is slidably connected to the base 1.

[0033] A slot hole 2 is provided at each of the four corners of the base 1. Through the arrangement of the slot hole 2, when punching the carbon fiber rear subframe 11, the debris generated by the punching can be discharged through the slot hole 2 and the rectangular support frame 3, preventing the accumulation of debris from affecting the rotation of the screw rod 4; the rectangular support frame 3 is fixedly installed in the corresponding slot hole 2; the connecting seat 9 slides in the corresponding slot hole 2, and the upper surface of the connecting seat 9 is lower than the upper surface of the base 1.

[0034] The clamping device includes a support platform 14, an axial hole 15, an L pressure plate 16, a rotating shaft 17 and an L clamping plate 18, and the support platform 14 is fixedly mounted on the outer side of the top of the tooling support 6. Through the setting of the support platform 14, the L pressure plate 16 can be supported. A coaxial axial hole 15 is provided at the top of the support platform 14; a rotating shaft 17 is fixedly mounted on one end of the L pressure plate 16, and the rotating shaft 17 is rotatably mounted in the axial hole 15. Through the setting of the rotating shaft 17 and the axial hole 15, the stability and smoothness of the L pressure plate 16 during rotation can be ensured. The other end of the L pressure plate 16 is vertically upward to provide the operator with a gripping force point for rotating the L pressure plate 16; one end of the L clamping plate 18 is fixedly mounted on the top surface of the tooling support 6, and the L clamping plate 18 spans the support platform 14, the transverse plate of the L-card plate 18 is above the transverse plate of the L-pressing plate 16. Through the setting of the L-card plate 18, when it is necessary to drill a hole in the carbon fiber rear subframe 11, the L-pressing plate 16 can be rotated to one side of the carbon fiber rear subframe 11 so that the L-pressing plate 16 is under the L-card plate 18, and the corner of the carbon fiber rear subframe 11 on the tooling bracket 6 can be fixed by the L-pressing plate 16 to prevent the carbon fiber rear subframe 11 from being separated from the tooling bracket 6. At the same time, the L-card plate 18 will clamp the L-pressing plate 16 to prevent the L-pressing plate 16 from being displaced. When disassembling the carbon fiber rear subframe 11 later, it is only necessary to lift the L-card plate 18 to move the L-pressing plate 16 away from above the carbon fiber rear subframe 11; the L-pressing plate 16 and the L-card plate 18 are rotatably clamped.

[0035] In this embodiment, first, the distance between the four tooling supports 6 is adjusted by the distance adjuster according to the size of the carbon fiber rear subframe 11; when adjusting, it is only necessary to rotate the screw rod 4 forward and backward by rotating the rotating cap 5, and the tooling supports 6 are driven to move under the forward and reverse rotation of the screw rod 4, so that each tooling support 6 can be moved to the desired position.

[0036] like Figure 1 and Figure 8As shown, when the carbon fiber rear subframe 11 needs to be punched, the four corners of the carbon fiber rear subframe 11 are placed into the corresponding positioning cavities 61 through the corresponding notches 62; then the corresponding adjusting screw 7 is rotated clockwise to apply pressure to the hydraulic oil through the adjusting screw 7, so that the hydraulic oil transmits the pressure to the external expansion rubber locking strip 63, causing the external expansion rubber locking strip 63 to expand outward and squeeze the carbon fiber rear subframe 11, thereby clamping the carbon fiber rear subframe 11 to prevent the carbon fiber rear subframe 11 from displacement during the punching process;

[0037] After the external expansion rubber locking strip 63 clamps the carbon fiber rear subframe 11, the L pressure plate 16 is rotated toward one side of the carbon fiber rear subframe 11 so that the other end of the L pressure plate 16 is rotated above the carbon fiber rear subframe 11. At this time, the transverse plate of the tooling bracket 6 will be under the L clamping plate 18, and the L pressure plate 16 can be used to fix the corner of the carbon fiber rear subframe 11 on the tooling bracket 6 to prevent the carbon fiber rear subframe 11 from being separated from the tooling bracket 6 during the punching process. At the same time, the L clamping plate 18 will clamp the L pressure plate 16 to prevent the L pressure plate 16 from moving.

[0038] After clamping, the base 1 is placed on the workbench of the five-axis machine tool. After the machine tool is set up for tool setting, the carbon fiber rear subframe 11 can be punched. After punching, the adjusting screw 7 is turned counterclockwise to release the pressure of the hydraulic oil. The external expansion rubber locking strip 63 will also shrink and reset. At the same time, the L-shaped card plate 18 is lifted to remove the L-shaped pressure plate 16 from the top of the carbon fiber rear subframe 11. At this time, the punched carbon fiber rear subframe 11 can be removed.

[0039] like Figure 2 As shown, when the carbon fiber rear subframe 11 needs to be tested for three-coordinates, the four corners of the carbon fiber rear subframe 11 are placed into the corresponding positioning cavities 61 through the corresponding notches 62; during the three-coordinates test, the carbon fiber rear subframe 11 can be clamped by the external expansion rubber locking strip 63, or it can be not clamped, because during the three-coordinates test, the carbon fiber rear subframe 11 will not be displaced. At the same time, after the carbon fiber rear subframe 11 passes the three-coordinates test, it is convenient to quickly replace the carbon fiber rear subframe 11, but the specific situation depends on the needs; then the base 1 is placed on the three-coordinates test table for three-coordinates test;

[0040] like Figure 3As shown, when the carbon fiber rear subframe 11 needs to be press-fitted with rubber bushings, the four corners of the carbon fiber rear subframe 11 are respectively placed into the corresponding positioning cavities 61 through the corresponding notches 62; when press-fitting the rubber bushings, the carbon fiber rear subframe 11 can be clamped by the outward-expanding rubber locking strip 63, or it can be left unclamped, because in the process of press-fitting the rubber bushings, the required rubber bushings will be pressed into the four corners of the carbon fiber rear subframe 11 at the same time, so the carbon fiber rear subframe 11 will not be displaced. At the same time, after the required rubber bushings are pressed into the carbon fiber rear subframe 11, it is convenient to quickly replace the carbon fiber rear subframe 11. , but the specific situation depends on the needs; then the base 1 is placed on the press table, and the rubber bushings 12 are placed at the holes corresponding to the four corners of the carbon fiber rear subframe 11. At the same time, the four corners of the carbon fiber rear subframe 11 are connected to the output end of the press through a punch 13, and the punch 13 is placed above the corresponding rubber bushing 12. Finally, the punch 13 is driven by the press to press the rubber bushing 12 into the through holes at the four corners of the carbon fiber rear subframe 11; at the same time, when the rubber bushings are pressed into the four corners of the carbon fiber rear subframe 11, the bottom of the positioning cavity 61 can position the rubber bushing to prevent the rubber bushing from being over-pressed.

[0041] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
