The workpiece body is placed in the placing ring, the positioning column is inserted into the first through hole, and at the same time, the positioning rod is inserted into the first through groove, thereby realizing the positioning of the workpiece body at two positions. Then, the operator loosens the bolt, rotates the connecting plate above the workpiece body, tightens the bolt again, and then starts the hydraulic cylinder. The hydraulic cylinder drives the connecting plate to move towards the workpiece body and presses the workpiece body through the pressing column, thereby reducing the possibility of the workpiece body rotating on the plane.

[0028] Please refer to Figures 1 - 4 , a positioning tooling plate for a milling machine, including a fixed disk 1.

[0029] In the specific implementation process, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a turntable 2 is rotatably arranged in the fixed disk 1, a support seat 3 is fixedly connected to the top of the turntable 2, a support plate 4 is slidably arranged on the support seat 3, a base 5 is fixedly connected to the bottom of the fixed disk 1, clamping plates 6 are slidably arranged on both sides of the top of the support plate 4, first positioning screws 7 are screwed on both sides of the fixed disk 1, and second positioning screws 8 are arranged at the four corners of the support plate 4.

[0030] The base 5 is installed on the workbench of the milling machine. The workpiece is placed on the top of the support plate 4. The two clamping plates 6 move towards each other to clamp and fix both sides of the workpiece, realizing the clamping process of the workpiece. When the horizontal angle of the workpiece needs to be adjusted during the machining process of the milling machine on the workpiece, rotate the support plate 4 to make the turntable 2 at its bottom rotate in the fixed disk 1, realizing the adjustment of the horizontal angle of the workpiece. When adjusting, observe the scale line on the top of the support seat 3 to determine the rotation angle. After rotating to the specified angle, tighten the first positioning screws 7 on both sides of the fixed disk 1 so that one end of the first positioning screw 7 abuts against the outer side of the turntable 2 to position the turntable 2. When the position of the workpiece needs to be adjusted during the machining process of the milling machine on the workpiece, loosen the second positioning screws 8 at the four corner positions of the support plate 4 to release the positioning of the support plate 4, so that the support plate 4 moves on the guide rails on both sides of the top of the support seat 3, thereby driving the workpiece to move to the specified position. After moving, tighten the second positioning screws 8 again to reposition the support plate 4, realizing the adjustment of the position of the workpiece.

[0031] A V-shaped groove is formed on one side of the clamping plate 6, and a rubber pad is arranged on the inner wall of the V-shaped groove. The V-shaped groove on one side of the clamping plate 6 can achieve the effect of clamping workpieces of different shapes, improving the applicability. When clamping, the rubber pad plays a protective role between the workpiece and the clamping plate 6.

[0032] The end of the first positioning screw 7 abuts against the outer side of the turntable 2, and the end of the second positioning screw 8 abuts against the top of the support base 3. The first positioning screw 7 abuts against the outer side of the turntable 2 to fix the turntable 2, and the second positioning screw 8 abuts against the top of the support base 3 to fix the support plate 4.

[0033] A convex block 9 is fixedly connected to the bottom of the turntable 2. The convex block 9 is an annular component, and the outer side of the convex block 9 is rotationally matched with the inner wall of the fixed disk 1. The annular convex block 9 at the bottom of the turntable 2 rotates in the groove of the fixed disk 1, which has a guiding and limiting effect on the turntable 2 and improves the stability of the turntable 2.

[0034] A worm 10 is rotatably arranged inside the support plate 4. A worm gear 11 is meshed with the worm 10. Both sides of the worm gear 11 are fixedly connected with threaded rods 12. Threaded blocks 13 are screwed on the threaded rods 12. By rotating the worm 10 to drive the worm gear 11 to rotate, the worm gear 11 drives the two threaded rods 12 with opposite threads on both sides to rotate, so that the two threaded blocks 13 move towards each other, and then drive the clamping plates 6 to move towards each other to clamp and fix both sides of the workpiece.

[0035] The top of the threaded block 13 is fixedly connected to the bottom of the clamping plate 6. One end of the worm 10 is fixedly connected with a hand crank 14, and it is convenient to drive the worm 10 to rotate through the hand crank 14.

[0036] Both sides of the bottom of the clamping plate 6 are fixedly connected with guide blocks 15. Guide grooves 16 are opened at the top of the support plate 4 and are used in cooperation with the guide blocks 15. When the clamping plate 6 moves, the guide blocks 15 at its bottom move in the guide grooves 16, which guides and limits the clamping plate 6 and improves the stability of the clamping plate 6 when it moves.

[0037] The working principle of a positioning tooling plate for a milling machine provided by the present utility model is as follows:

[0038] When in use, the base 5 is installed on the working table of the milling machine, and the workpiece is placed on the top of the support plate 4. By rotating the worm 10 to drive the worm gear 11 to rotate, the two threaded blocks 13 drive the clamping plates 6 to move towards each other to clamp and fix both sides of the workpiece, realizing the clamping process of the workpiece. Rotate the support plate 4 so that the turntable 2 at its bottom rotates in the fixed disk 1, realizing the adjustment of the horizontal angle of the workpiece. After the adjustment is completed, fix it by tightening the first positioning screw 7. The support plate 4 moves on the guide rails on both sides of the top of the support base 3, driving the workpiece to move to the specified position. After moving, tighten the second positioning screw 8 again to reposition the support plate 4, realizing the adjustment of the position of the workpiece.

[0039] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present utility model.
