Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Referring to Figures 1-5 ,, a special fixture mechanism for material testing milling machine processing includes a fixture bottom plate 1 and a fixture top plate 2. The fixture bottom plate 1 and the fixture top plate 2 are connected by a plurality of connecting columns 3. A plurality of first fixing blocks 4 are arranged on the fixture bottom plate 1. A first screw rod 5 is threadedly connected in each first fixing block 4. One end of each first screw rod 5 is movably connected to a moving plate 6. A plurality of first connecting rods 7 and second connecting rods 8 are rotatably connected to the bottom end of the fixture top plate 2. The first connecting rod 7 and the second connecting rod 8 at the same position are rotatably connected to each other in a cross manner. The bottom of the same end of the first connecting rod 7 and the second connecting rod 8 are both connected to a driving shaft 9. The two driving shafts 9 are slidably connected in the same moving plate 6. The top of both ends of the first connecting rod 7 are both connected to a first sliding shaft 10. The top of both ends of the second connecting rod 8 are both connected to a second sliding shaft 11. A plurality of second fixing blocks 12 and positioning blocks 13 are arranged on the fixture top plate 2. The positions of the second fixing blocks 12 and the positioning blocks 13 are parallel and corresponding to each other. A second screw rod 14 is threadedly connected in each second fixing block 12. One end of each second screw rod 14 is movably connected to a clamping block 15. The clamping block 15 is arranged between the second fixing block 12 and the positioning block 13. A plurality of mutually parallel positioning plates 16 are slidably connected to the fixture top plate 2. Every two adjacent positioning plates 16 are respectively arranged on both sides of the area between the clamping block 15 and the positioning block 13. The first sliding shaft 10 and the second sliding shaft 11 are slidably connected in the same positioning plate 16.

[0023] Place the test materials on the top plate 2 of the fixture in sequence. Rotate the first screw rod 5 in the reverse direction so that the moving plate 6 moves in the direction of the first fixed block 4. Through the connection between the driving shaft 9 and the moving plate 6, the first connecting rod 7 and the second connecting rod 8 generate synchronous inward rotation. Through the connection of the first sliding shaft 10 and the second sliding shaft 11, the two positioning plates 16 move synchronously inward, thereby positioning both sides of the test materials. At the same time, the second screw rod 14 can be rotated so that the clamping block 15 pushes the test materials towards the positioning block 13, thereby achieving the effect of positioning and clamping all around the test materials.

[0024] Specifically, in this embodiment, the number of the first fixed blocks 4 is the same as that of the second fixed blocks 12, and the number of the positioning plates 16 is twice the number of the second fixed blocks 12.

[0025] Specifically, in this embodiment, a first support shaft 17 is connected to the end of the first screw rod 5, and the first support shaft 17 is rotatably connected inside one end of the moving plate 6, so that the rotation of the first screw rod 5 and the movement of the moving plate 6 are independent of each other and synchronous.

[0026] Specifically, in this embodiment, a positioning shaft 18 is connected to the bottom end of the top plate 2 of the fixture. The central parts of the first connecting rod 7 and the second connecting rod 8 are both rotatably connected to the positioning shaft 18, providing a fulcrum for the rotation of the first connecting rod 7 and the second connecting rod 8 and preventing the first connecting rod 7 and the second connecting rod 8 from separating from the top plate 2 of the fixture.

[0027] Specifically, in this embodiment, a second support shaft 19 is connected to the end of the second screw rod 14, and the second support shaft 19 is rotatably connected inside one end of the clamping block 15, so that the rotation of the second screw rod 14 and the movement of the clamping block 15 are independent of each other and synchronous.

[0028] Specifically, in this embodiment, an arc-shaped groove group 20 is formed on the top plate 2 of the fixture. The arc-shaped groove group 20 is composed of four arc-shaped grooves arranged in a circular shape with the center of the positioning shaft 18 as the center. The two first sliding shafts 10 and the two second sliding shafts 11 are respectively slidably connected in the corresponding arc-shaped grooves, providing a moving space for the first sliding shaft 10 and the second sliding shaft 11 to penetrate through the top plate 2 of the fixture.

[0029] Specifically, in this embodiment, a guiding groove 21 is formed on the top plate 2 of the fixture. The guiding groove 21 is arranged perpendicular to the long side of the positioning plate 16. A guiding block 22 is connected to the bottom end of each positioning plate 16, and several guiding blocks 22 are all slidably connected in the guiding groove 21, preventing the positioning plate 16 from shaking and ensuring the horizontal stability of the movement of each positioning plate 16.
