[0031] Please refer to Figures 1-4 , the present utility model provides a technical solution: a fixing fixture for machining, including a bottom plate 1, a chute 2 is opened on the bottom plate 1, side plates 3 are installed on both sides of the upper end of the bottom plate 1, a motor 4 is installed at the lower end of the bottom plate 1, a driving gear 5 is arranged on the output end of the motor 4, and a linkage gear 6 is connected to the side of the driving gear 5, a driving lead screw 7 is installed on the linkage gear 6, and a linkage frame 8 is arranged on the driving lead screw 7;

[0032] In this example, an installation frame 9 is installed at the upper end of the linkage frame 8, and a through rod 10 is installed on the side of the installation frame 9. A first installation plate 11 or a second installation plate 15 is installed in the installation frame 9. One end of the first installation plate 11 is installed with a first anti-slip strip 12, and the other end of the first installation plate 11 is connected with an installation screw rod 13. An installation nut 14 is arranged on the installation screw rod 13. The installation nut 14 is threadedly connected with the installation screw rod 13 and the docking screw rod 17 respectively. Through the connection between the installation nut 14 and the installation screw rod 13 and the docking screw rod 17, the installed first installation plate 11 or the second installation plate 15 can be installed and fixed, and the flexible replacement of the installation plate can be realized according to the shape of the processed workpiece.

[0033] A docking block 16 is installed on the back of the second installation plate 15, and a docking screw rod 17 is arranged on the docking block 16. A positioning seat 18 is arranged in the second installation plate 15.

[0034] In this example, the driving gear 5 and the linkage gear 6 are meshed, and the linkage gear 6 and the driving lead screw 7 are integrally designed. The two ends of the driving lead screw 7 are connected to the bottom plate 1 through bearings. A lead screw nut is installed at the connection between the linkage frame 8 and the driving lead screw 7. The meshing between the driving gear 5 and the linkage gear 6 enables the driving lead screw 7 to rotate synchronously. The rotating driving lead screw 7 drives the linkage frame 8 thereon to cooperate with the driving lead screw 7 to form a lead screw operation structure.

[0035] In this example, the linkage frame 8 and the installation frame 9 are integrally designed. The linkage frame 8 is nested and slidably connected with the chute 2, and the installation frame 9 is respectively snap-connected with the first installation plate 11 and the second installation plate 15. The sliding of the linkage frame 8 in the chute 2 realizes the movement of the installation frame 9 thereon. The two moving installation frames 9 approach each other to form a clamping structure for clamping mechanical workpieces.

[0036] In this example, a positioning seat 18 is arranged in the second installation plate 15. The positioning seat 18 is designed in a sector shape, a triangular shape, an "L" shape or other structures. The positioning seat 18 in the shape of a sector, a triangle or an "L" shape can flexibly clamp and position mechanical parts to realize the adaptation of workpieces with different shapes. An adjusting screw rod 19 and a limiting through rod 21 are installed on the side of the positioning seat 18. The adjusting screw rod 19 penetrates through the second installation plate 15, and the second installation plate 15 penetrates through the limiting through rod 21. The limiting through rod 21 improves the stability of the movement of the positioning seat 18. A butterfly nut 20 is arranged on the adjusting screw rod 19, and the screwing of the butterfly nut 20 on the adjusting screw rod 19 realizes the adjustment of the position of the positioning seat 18.

[0037] Working principle: According to Figures 1-4As shown, different first mounting plates 11 or positioning seats 18 are installed according to the machined mechanical workpiece. When machining a mechanical workpiece in a straight bar state, the first mounting plate 11 needs to be installed. Then, the mounting screw 13 is inserted into the mounting frame 9, and then the mounting nut 14 is taken out to fix the mounting screw 13. The workpiece can be fixed by the first anti-slip strip 12. When installing workpieces of different shapes, the corresponding positioning seat 18 is taken out and installed in the second mounting plate 15. When installing, the limit insertion rod 21 and the adjustment screw 19 on the side of the positioning seat 18 are inserted into the side of the second mounting plate 15, and the gap between the positioning seats 18 is adjusted by screwing the wing nut 20 with the adjustment screw 19 to adapt to workpieces of different shapes;

[0038] According to Figure 1 and Figure 2 As shown, after the fixture is fixedly installed, the mechanical workpiece is clamped by the fixture. The motor 4 is started to drive the driving gear 5 to engage and drive the linkage gear 6 to rotate. The linkage gear 6 drives the driving lead screw 7 to rotate. The lead screw nut at the lower end of the linkage frame 8 installed on the driving lead screw 7 moves in cooperation with it, and drives the first mounting plate 11 on the mounting frame 9 to move, so as to clamp the mechanical workpiece.

[0039] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
