[0024] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] like Figure 1 to Figure 7As shown, a tooling fixture includes a base plate 1, a panel 2, a fastening device, a positioning device, and an anti-fool device. The panel 2 is installed on the side of the base plate 1, the fastening device is arranged on the surface of the panel 2, and the positioning device and the anti-fool device are both installed on the panel 2.

[0026] In this embodiment, the fastening device includes an adsorption device and a clamp 3. The adsorption device includes an adsorption curved surface 4, an air guide hole 5, an air pipe 6, and a vacuum pump (not shown in the figure). The adsorption curved surface 4 is arranged in the middle of the panel 2. The air guide hole 5 is arranged in the middle of the adsorption curved surface 4, penetrates the panel 2 and is connected to the vacuum pump (not shown in the figure) through the air pipe 6 to form an air guide channel. The clamp 3 is installed on the panel 2 near the four end corners of the adsorption curved surface 4 by screws 7. The clamp 3 and the panel 2 are both provided with screw holes 8 for the screws 7 to pass through.

[0027] In this embodiment, the clamp 3 is of model GH-201.

[0028] In this embodiment, the adsorption curved surface 4 is provided with mutually interconnected transverse air suction grooves 9 and longitudinal air suction grooves 10, which are connected to a vacuum pump (not shown in the figure) through air guide holes 5 and air pipes 6 to form an air guide channel.

[0029] In this embodiment, a relief groove 11 is provided on the panel 2 between the clamp 3 and the adsorption curved surface 4 .

[0030] In this embodiment, a back panel 12 is connected between both ends of the back side of the panel 2 and the bottom plate 1. The back panel 12 is a triangular back panel. One right-angled side of the back panel 12 is connected to the back side of the panel 2 via a screw 7. The other right-angled side of the back panel 12 is connected to the bottom plate 1 via a screw 7. Screw holes 8 for the screws 7 to pass through are provided on the bottom plate 1 and the panel 2.

[0031] In this embodiment, the positioning device is a lateral spring column 13, which is installed on the panel 2 on the surface where one of the avoidance grooves 11 is located. The model of the lateral spring column 13 is VCN524-B.

[0032] In this embodiment, the anti-foolproof device includes an anti-foolproof block 14 and an anti-foolproof column 15 installed on the anti-foolproof block 14. The anti-foolproof block 14 is installed on the panel 2 at the bottom of the adsorption surface 4 by screws 7. The anti-foolproof block 14 and the panel 2 are both provided with screw holes 8 through which the screws 7 pass.

[0033] In this embodiment, the base plate 1 is mounted on a workbench for workpiece processing by means of screws 7 .

(In this process, the correctness of the placement direction of the workpiece to be processed is judged by the anti-fool column 15 on the anti-fool device. If the workpiece to be processed is placed upside down, the existence of the anti-fool column 15 will cause the workpiece to be processed to not be placed.) The side of the curved surface workpiece to be processed is placed in the avoidance groove 11, and the handle of the clamp 3 is pressed. The rubber surface of the clamp 3 pressure head is pressed against the curved surface of the curved surface workpiece to be processed, and the vacuum pump (not shown in the figure) is started. The horizontal suction groove 9 and the longitudinal suction groove 10 on the adsorption curved surface 4 are connected to the vacuum pump (not shown in the figure) through the air guide hole 5 and the air pipe 6 to form an air guide channel, so that the curved surface workpiece to be processed is adsorbed more tightly. The utility model uses an adsorption device and a clamp 3 to achieve double fastening of the curved workpiece to be processed, thereby improving the stability of the curved workpiece during processing, avoiding shaking of the curved workpiece during processing, or even falling of a vertically placed curved workpiece, improving the processing accuracy of the curved workpiece, ensuring that its dimensional accuracy meets the specified technical requirements, and improving the processing quality of the curved workpiece.

[0035] In summary, the utility model achieves the expected effect.
