[0012] Furthermore, a groove matching the cutter is formed at the top of the base.

[0013] The beneficial effects of the utility model are:

[0014] The utility model is provided with an adjusting screw and a nut. When in use, the adjusting screw is rotated so that the adjusting screw pushes the clamping plate to move through the nut, and then the clamping plate can be adjusted to a suitable position. The supporting plate is then pushed downward by cylinder 2. At this time, the inner wall of the through groove pushes the movable plate to move toward each other.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1 Please refer to Figure 1-Figure 4 , the utility model provides a technical solution:

[0023] A high-precision cutting platform positioning mechanism comprises a base 1, a U-shaped frame 2 is fixedly provided on the top of the base 1, a movable plate 3 is symmetrically slidably provided on the top of the base 1, and the movable plates 3 are all located directly below the U-shaped frame 2, a nut 4 is fixedly embedded in the movable plate 3, an adjusting screw 5 is threaded and rotatably provided in the nut 4, one end of the adjusting screw 5 extends to the outside of the U-shaped frame 2, and the other end of the adjusting screw 5 is rotatably connected with a clamping plate 6, a support plate 7 is slidably provided in the upper part of the U-shaped frame 2, a through groove 8 matching the movable plate 3 is symmetrically penetrated through the top of the movable plate 3, a fixed seat 9 is fixedly provided at the bottom end of the fixed seat 9, a pressing plate 10 is slidably embedded at the bottom end of the fixed seat 9, a transverse plate 11 is fixedly provided on the upper part of one side of the U-shaped frame 2, a cylinder 12 is fixedly provided at the bottom end of the transverse plate 11, and a cutter 13 is fixedly connected to the output end of the cylinder 12.

[0024] Specifically, Figure 1-Figure 4 As shown, the front top and the rear top of the base 1 are symmetrically provided with slide grooves 14, and sliders 15 are slidably provided in the slide grooves 14. The tops of the sliders 15 are fixedly connected to the bottom ends of the adjacent movable plates 3, and one side of the sliders 15 is fixedly provided with springs 16, and the other ends of the springs 16 are fixedly connected to the inner walls of one side adjacent to the slide grooves 14. The support plate 7 is moved downward, so that the inner walls of the through grooves 8 push the movable plates 3 to move toward each other. At this time, the movable plate 3 will drive the clamping plate 6 to move through the adjusting screw 5, and at the same time, the movable plate 3 will drive the slider 15 to squeeze the spring 16 in the slide groove 14.

[0025] Specifically, Figure 1-Figure 4 As shown, a cylinder 2 17 is fixedly provided at the bottom end of the horizontal portion of the U-shaped frame 2, and the output end of the cylinder 2 17 is fixedly connected to the top end of the support plate 7, and a plurality of springs 2 18 are fixedly provided in an array on the inner wall of the top end of the fixed seat 9, and the bottom ends of the springs 2 18 are fixedly connected to the top end of the pressure plate 10, and anti-slip pads are fixedly provided on the clamping plate 6 and the pressure plate 10. When the pressure plate 10 contacts the top end of the workpiece, the fixed seat 9 continues to move downward, so that the fixed seat 9 squeezes the spring 2 18, and the spring 2 18 applies a downward force to the pressure plate 10, so that the workpiece can be pressed tightly.

[0026] Example 2 Please refer to Figure 1-Figure 4 The difference between this embodiment and embodiment 1 is that a groove 19 matching the cutter 13 is provided at the top of the base 1. By providing the groove 19, the cutter 13 is prevented from contacting the base 1, thereby effectively protecting the cutter 13.

[0027] The working principle of the utility model is as follows: when in use, by rotating the adjusting screw 5, the adjusting screw 5 pushes the clamping plate 6 to move through the nut 4, and then the clamping plate 6 can be adjusted to a suitable position to place the workpiece on the base 1. At this time, the support plate 7 is pushed downward by the cylinder 17, so that the inner wall of the through groove 8 pushes the movable plate 3 to move toward each other. At this time, the movable plate 3 will drive the clamping plate 6 to move through the adjusting screw 5, so that the workpiece can be clamped and fixed by the clamping plate 6. At the same time, the movable plate 3 will drive the slider 15 to squeeze the spring 16 in the slide groove 14, and the support plate 7 will drive the fixed seat 9 and the pressure plate 10 to press and fix the workpiece downward. When the pressure plate 10 conflicts with the top of the workpiece, the fixed seat 9 continues to move downward, so that the fixed seat 9 squeezes the spring 18, and the spring 18 applies a downward force to the pressure plate 10, so that the workpiece can be pressed.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
