This poses a challenge to the versatility of bar preparation equipment, especially for the clamping of billets of different specifications, the difficulty is particularly prominent. In addition, when the new and efficient metal bar test sample preparation equipment uses a hollow drill bit to drill and mill the billet, it is easy to penetrate the edge of the billet, resulting in the wall edge being too thin. This will not only reduce the mechanical properties of this part and its related parts, but may also cause an overall mechanical imbalance between the billet and the clamping body system, and even cause the entire system to collapse. Therefore, it is urgent to develop a CNC universal multifunctional cylindrical metal billet clamping device to solve the problems existing in the prior art. Summary of the invention

[0006] At least two piston rods are arranged on one of the clamping cylinders, and the two piston rods are located in the same horizontal plane.

[0007] Furthermore, the contact end of the piston rod and the columnar blank is fixedly connected with an elastic abutment joint, the elastic abutment joint is a rubber block, and the contact surface between the rubber block and the columnar blank is provided with anti-slip patterns.

[0021] In view of the problems existing in the prior art, the present invention provides a CNC universal multifunctional cylindrical metal blank clamping device, which is described in detail below in conjunction with the accompanying drawings.

[0022] Example 1

[0023] See also Figure 1-Figure 4 As shown, the technical solution adopted in this specific embodiment is: a CNC universal multifunctional cylindrical metal blank clamping device, which is attached to the metal bar material inspection sample preparation equipment, specifically including a base 1, on which a plurality of clamping blocks 2 are fixedly installed, and the plurality of clamping blocks 2 are located at the same level and arranged on the same straight line, and each of the clamping blocks 2 is provided with at least one fixed jaw 21, and a clamping cylinder 3 is provided on the opposite side of the fixed jaw 21 of the clamping block 2, and the clamping cylinder 3 is controlled by a hydraulic system (not shown in the figure), and the clamping cylinder 3 is fixed on the base 1, and the rod end of the piston rod 31 of the clamping cylinder 3 is arranged toward the fixed jaw 21.

[0024] It should be specifically explained that the clamp block 2 is fixedly mounted on the base 1 by screws, and the fixed jaw 21 is a V-shaped groove opening toward the clamping cylinder 3 , and the setting of the V-shaped groove can match columnar blanks 4 of different sizes.

[0025] The clamp block 2 is a single-sided clamp block structure with a fixed jaw 21; or the clamp block 2 is a double-sided clamp block structure with two fixed jaws 21, and the two fixed jaws 21 are respectively arranged on the left and right sides of the clamp block 2. A single-sided clamp block structure or a double-sided clamp block structure or a combination of the single-sided clamp block structure and the double-sided clamp block structure can be arranged on a base 1.
