They are mainly composed of positioning devices, clamping devices, clamping bodies, connecting elements and tool setting elements. During milling, the cutting force is large, and it is intermittent cutting, so the vibration is large. Therefore, the clamping force of the milling machine fixture is large, and the fixture rigidity and strength requirements are relatively high. According to the feeding method during milling, the milling machine fixture can be divided into three types: linear feed type, circular feed type and mold feed type. There are many milling machine fixtures, among which the tiltable guide rod angle flat-nose pliers are one of them. The bottom of the adjustable angle flat-nose pliers is adjusted by the tilting guide rail;

[0019] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0020] Reference Figure 1 - Figure 4A fixture for milling machine processing includes a fixed base 1, a slide groove 5 is opened on the upper surface of the fixed base 1, two movable base blocks 8 are arranged inside the slide groove 5, the inner walls of the two movable base blocks 8 are commonly threadedly connected with a first screw rod 7, the outer surface of the first screw rod 7 is transmission-connected to the inner wall of the fixed base 1, and the upper surfaces of the two movable base blocks 8 are commonly fixedly installed with a mounting plate 3, the bottom surface of the mounting plate 3 is in contact with the upper surface of the fixed base 1, and two groups of guide rods 15 are fixedly installed on the upper surface of the mounting plate 3, and the outer surface of each group of guide rods 15 is slidably connected with a sliding bearing 6, and the outer surface of each sliding bearing 6 is commonly fixedly installed with a lifting platform 4, the bottom surface of the lifting platform 4 is in contact with the upper surface of the mounting plate 3, and the outer surface of each group of guide rods 15 is threadedly connected with a limiting nut 14.

[0021] Reference Figure 4 Two groups of hidden grooves 16 are provided on the bottom surface of the lifting platform 4, and each limiting nut 14 is located in the hidden groove 16. The hidden groove 16 is provided to hide the limiting nut 14 without affecting the contact between the lifting platform 4 and the mounting plate 3.

[0022] Reference Figure 3 and Figure 4 Two adjusting base plates 13 are fixedly installed on the upper surface of the lifting platform 4, and the outer surfaces of the two adjusting base plates 13 are rotatably connected with a bench clamp plate 12. By adjusting the base plates 13 and the bench clamp plate 12, the bench clamp plate 12 can be rotated in conjunction with the adjusting base plates 13 to adjust the angle position of the clamp jaws. For its specific coordination and adjustment functions, please refer to the tiltable guide rod type angle flat-nose pliers.

[0023] Reference Figure 2 and Figure 3 The inner wall of the vise plate 12 is threadedly connected with a second screw 10, and the outer surfaces of the first screw 7 and the second screw 10 are fixedly installed with hand rods 9. Through the second screw 10, spiral transmission can be performed to convert rotational motion into linear motion. Through the hand rod 9, the first screw 7 and the second screw 10 can be easily rotated.

[0024] Reference Figure 3 A movable clamping plate 11 is provided on the upper surface of the vise plate 12. The interior of the movable clamping plate 11 is rotatably connected to the outer surface of the second screw 10. The movable clamping plate 11 cooperates with the vise plate 12 to move according to the position of the movable clamping plate 11 to clamp the workpiece.

[0025] Reference Figure 2 The outer surface of the left end of the first screw rod 7 is threadedly connected to the limiting end cover 2, and the right side of the limiting end cover 2 contacts the left side of the fixed base 1. The limiting end cover 2 is used to limit the first screw rod 7 and prevent the first screw rod 7 from moving left and right.

[0026] Working principle: When in use, install the fixed base 1 at the position where it is needed. After determining the position, clamp the workpiece according to the clamping position and angle required by the workpiece. When clamping the workpiece horizontally, the workpiece can be placed on the vise plate 12 and located between the movable clamp plate 11 and the vise plate 12. According to the size of the workpiece, use the hand lever 9 to rotate the second screw 10. As the second screw 10 rotates between the movable clamp plate 11 and the vise plate 12, the movable clamp plate 11 fixes the workpiece. When clamping the workpiece at a certain angle, the vise plate 12 can be rotated. The clamp plate 12 is rotated in conjunction with the adjusting base plate 13, and then the bench clamp plate 12 is fixed, so that the clamping position of the movable clamp plate 11 and the bench clamp plate 12 is changed. In order to facilitate the change of the position of the overall clamp, the hand lever 9 can be used to rotate the first screw rod 7, and the first screw rod 7 cooperates with the movable bottom block 8 to move the mounting plate 3 to change the left and right position of the bench clamp plate 12. When the height needs to be adjusted, the lifting platform 4 can be directly lifted. After the height of the lifting platform 4 is adjusted, the limit nut 14 is screwed, and the limit nut 14 limits the descent of the lifting platform 4. The overall position can be flexibly adjusted as needed.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
