[0022] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0023] Please refer to Figures 1-4The utility model proposes a convenient material clamp for CNC machining, including a fixed frame 1, the upper surface of the fixed frame 1 is provided with two placement areas 2, the upper surface of the fixed frame 1 is provided with a first placement groove on one side of the two placement areas 2, and a first clamping assembly 3 is placed in the two first placement grooves, and the first clamping assembly 3 includes a fixed seat 31, the fixed seat 31 is fixedly connected to the inner wall of the first placement groove, one side of the fixed seat 31 is vertically slidably connected to the first lifting block 32, and a first protruding block 33 is slidably provided on one side of the first lifting block 32, and the side opposite to the first protruding block 33 is a first inclined surface, and the two first inclined surfaces cooperate, and the height of the first lifting block 32 and the first protruding block 33 is greater than the depth of the first placement groove, and the first inclined surface of the first lifting block 32 is fixed The first T-shaped block 34 is fixedly connected, and an inclined first T-shaped slot is provided on the first inclined surface of the first protruding block 33. The first T-shaped block 34 cooperates with the first T-shaped slot. When in use, two materials are placed in the placement area 2, and the first lifting block 32 slides downward on the fixed seat 31, and pushes the first protruding block 33 to move horizontally through the first T-shaped block 34 and the first T-shaped slot. The two first protruding blocks 33 are squeezed on one side of the material to fix the material in the placement area 2. When the material needs to be released, it is only necessary to push the first T-shaped block 34 upward, and the first T-shaped block 34 drives the first protruding block 33 to rise. Under the action of gravity, the first protruding block 33 slides down along the first T-shaped block 34, so that the first protruding block 33 is away from the material, and then no longer squeezes the material, which makes it convenient to take out the material. The structure is simple and the use is convenient and quick.

[0024] like Figure 2 and Figure 3As shown, two second placement slots are provided between the two placement areas 2, and a second clamping assembly 4 is provided in the second placement slot. The second clamping assembly 4 includes a second lifting block 41, and the second lifting block 41 is placed in the second placement slot. The side of the second lifting block 41 is tightly attached to the second placement slot, and second protruding blocks 42 are slidably provided on both sides of the second lifting block 41. A second inclined surface is provided on the side opposite to the second protruding block 42. The height of the second lifting block 41 and the second protruding block 42 is greater than the depth of the second placement slot. An inclined second T-shaped block 43 is fixedly connected to the second inclined surface on both sides of the second lifting block 41, and an inclined second T-slot is provided on one side of the second protruding block 42. The second T-shaped block 43 and the second T-slot are In coordination, a plurality of cylinders 5 are fixedly connected to the lower surface of the fixed frame 1. The number of cylinders 5 is the same as the number of placement slots. Each first lifting block 32 and the second lifting block 41 are fixedly connected to the telescopic rod of a cylinder 5. The second clamping assembly 4 is located between the two materials. When the material is placed in the placement area 2, one side is extended by the first protruding block 33 to squeeze and fix it. Then the cylinder 5 pulls the second lifting block 41 to slide downward, through the second T-shaped blocks 43 and the second T-shaped slots on both sides, and at the same time pushes the second protruding blocks 42 on both sides to slide toward the side of the material until the material is squeezed and fixed. The material is squeezed and fixed in two directions, making the material more stable in the placement area 2, avoiding the movement of the material during processing and affecting the processing accuracy.

[0025] like Figure 1 and Figure 2 As shown, the upper surface of the fixing frame 1 is located on one side of the placement area 2 and a plurality of clamping bosses 6 are provided. The clamping boss 6 is located around the placement area 2, and the clamping boss 6 is away from the first protruding block 33 and the second protruding block 42. The placement area 2 is higher than the surface of the fixing frame 1. The upper surfaces of all the clamping bosses 6 are provided with two circular through grooves. The upper surface of the fixing frame 1 is located at the position of the clamping boss 6 and is fixedly connected to two insertion rods 7. The two insertion rods 7 cooperate with the two circular through grooves. The placement area 2 is higher than the fixing frame 1. After the material is placed in the placement area 2, the material rests on one side of the clamping boss 6. At this time, the first protruding block 33 and the second protruding block 42 extend from the other two sides to squeeze the material. With the obstruction of the clamping bosses, the material is fixed, and the material is fit with the placement area 2 to avoid deviation. At the same time, when the material needs to be taken out, the first protruding block 33 and the second protruding block 42 leave the material, and the staff can take it out directly from the placement area 2. Compared with the placement groove, the placement area 2 is higher than the fixing frame 1, and it is more convenient to take out the material.

[0026] Working principle: After the material is placed in the placement area 2, the material rests on one side of the clamping boss 6, and the cylinder 5 pulls the first lifting block 32 to slide downward on the fixed seat 31. The first T-shaped block 34 and the first T-shaped slot push the first protruding block 33 to move horizontally. The two first protruding blocks 33 are squeezed on one side of the material to fix the material in the placement area 2. The cylinder 5 pulls the second lifting block 41 to slide downward, through the second T-shaped blocks 43 and the second T-shaped slot on both sides, and at the same time pushes the second protruding blocks 42 on both sides to slide toward the side of the material until the material is squeezed and fixed.
