[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] like Figure 1-4 As shown, a clamping device for processing an axial hole of an aluminum material comprises a bracket 1, a sleeve 2 and two clamping assemblies. The bracket 1 has two, and a clamping hoop 8 is provided at the top of the bracket 1. The clamping hoops 8 of the two brackets 1 are coaxially arranged, and the two clamping hoops 8 are both sleeved on the sleeve 2, and the two brackets 1 are located on the same side of the sleeve 2;

[0021] There are two clamping assemblies, which are respectively located at two ends of the sleeve 2;

[0022] The clamping assembly includes two support blocks 3 and a top block 4, the two support blocks 3 and the top block 4 are located in the same plane, the plane where the two support blocks 3 and the top block 4 are located is perpendicular to the axis of the sleeve 2, the two support blocks 3 and the top block 4 are both located in the sleeve 2, the two support blocks 3 are fixed on the inner wall of the sleeve 2, a threaded hole is provided on the cylinder wall of the sleeve 2, a bolt 5 is provided in the threaded hole, the bolt 5 is inserted into the sleeve 2 from the outside of the sleeve 2, two limiting holes are provided on both sides of the threaded hole of the sleeve 2, a limiting rod 6 is provided in each of the two limiting holes, the limiting rod 6 is vertically arranged, the upper end of the limiting rod 6 is located outside the sleeve 2, the lower end of the limiting rod 6 passes through the limiting hole and is fixedly connected to the top block 4, the bolt 5 and the two limiting rods 6 are parallel;

[0023] A connecting block 7 is provided between the top block 4 and the end of the bolt 5, and a bearing is provided inside the connecting block 7. The outer ring of the bearing is connected to the connecting block 7, and the inner ring of the bearing is fixedly connected to the end of the bolt 5.

[0024] The included angle of the two bolts 5 of the two clamping assemblies is 180°. In fact, the bolt 5 of one clamping assembly is located above the sleeve 2, and the bolt 5 of the other clamping assembly is located below the sleeve 2. This design is mainly to make the four support blocks 3 and the two top blocks 4 distributed more evenly, and to apply force to the same aluminum material through the upper and lower parts, so that the position of the aluminum material can be fixed more accurately.

[0025] Preferably, the two support blocks 3 and one top block 4 of the same clamping assembly are respectively located at the three corners of an isosceles triangle, and the position of the top block 4 is the vertex of the isosceles triangle. The vertex angle of the isosceles triangle is an acute angle. This design is mainly to make the two support blocks 3 and one top block 4 more evenly distributed to ensure the stability of the aluminum clamping.

[0026] Preferably, the distance between two support blocks 3 of the same clamping assembly is greater than the width of the top block 4 .

[0027] Preferably, rubber blocks 9 are provided on the top block 4 and the support block 3 .

[0028] Here, the aluminum material is passed through the sleeve 2, and then one end of the aluminum material is placed on two support blocks 3, that is, it is stably prevented between the two support blocks 3, and the other end is pressed on the top block 4 of another clamping assembly. At this time, the two support blocks 3 and one top block 4 actually realize three-point stable support for the aluminum material, and then the bolt 5 in the downward direction is turned to make the top block 4 on the bolt 5 move upward, and one end of the aluminum material is lifted up until it is supported by the two support blocks 3 of the clamping assembly where the bolt 5 is located. In this way, one end of the aluminum material is stably clamped and fixed, and then the bolt 5 located above the sleeve 2 is screwed downward to press the aluminum material downward until it is stably fixed. At this time, both ends of the aluminum material are clamped and fixed, and the outer wall of the aluminum material receives clamping forces in 6 different directions, which can prevent the aluminum material from spinning during processing.

[0029] Compared with the prior art, the clamping device for processing the axial hole of aluminum material realizes the clamping of the aluminum material through the cooperation of the dynamic top block 4 and the static support block 3, and two clamping components are arranged at both ends of the sleeve 2, which can not only improve the clamping accuracy, but also improve the clamping stability, and has strong practicality.
