Problems solved by technology

[0005] In order to overcome the above-mentioned problems, the present invention mainly solves the problems such as difficulty in NDT sample processing, long time and high cost, and provides a special fixture and processing method for NDT sample processing. The plane part is used for positioning, which is easy to clamp and save Time; no need to repeatedly measure and modify the processing program. After one clamping and correcting the positioning, the NDT sample that meets the design requirements can be precisely processed. On the premise of ensuring quality, the work efficiency is improved and the processing cost is reduced.

Embodiment 1

[0026]Such asfigure 1 ,2A special fixture for NDT sample processing is shown, including a fixture 1 with a clamping bayonet 11, one side of the clamping bayonet 11 is provided with a plane positioning point, the plane positioning point includes three plane positioning Cylinder 2, the other side of the clamping bayonet 11 is provided with a corresponding lock column 3; one side of the clamp 1 is close to the working platform of the wire-controlled cutting machine tool so that the plane determined by the three plane positioning columns 2 is vertical It is used on the working platform of CNC wire cutting machine tool.

[0027]According to the geometric theorem of three points to determine a plane, use three small cylinders to weld and fix the clamping bayonet 11 on one plane, and then install three bolts on the other plane to form three plane positioning cylinders to ensure three small The cylinder and the three bolts are basically on the same axis. Finally, each surface of the fixture an...

Embodiment 2

[0034]Such asimage 3 ,4A special fixture for NDT sample processing is shown, including a fixture 1 with a clamping bayonet 11, one side of the clamping bayonet 11 is provided with a plane positioning point, and the plane positioning point includes at least three planes Positioning column 2, the other side of the clamping bayonet 11 is provided with a corresponding lock column 3; one side of the clamp 1 is close to the working platform of the wire-controlled cutting machine tool, so that the three planes are positioned on the plane determined by the column 2 The working platform is perpendicular to the CNC wire cutting machine tool.

[0035]In this embodiment, the plane positioning point is composed of three plane positioning cylinders 2. If there are samples in special circumstances, four or more plane positioning cylinders 2 can be used.

[0036]The lock column 3 is a bolt, and the bolt is screwed to one side of the clamping bayonet 11, and the NDT sample 4 is fixed by tightening the bol...

Embodiment 3

[0044]The present invention provides a NDT sample processing method, which includes the following steps: 1) Fix the special fixture for NDT sample processing on the CNC wire cutting work platform; 2) Check the plane determined by the three fixed plane positioning cylinders and the CNC wire cutting The verticality of the working platform of the machine tool; 3) Correct the verticality of the plane determined by the three fixed plane positioning cylinders and the working platform of the CNC wire-cutting machine tool; 4) Install the NDT sample in the clamping port of the fixture, and lock the bolt Fix it; 5) Call the processing program for processing; 6) Detect each processing size; 7) Adjust and modify the processing program, and finally process a shape. Its clamping is convenient, and the work efficiency is greatly improved; using the NDT special fixture, each NDT sample only needs to be processed once, which improves the processing efficiency and reduces the processing cost; avoids ...

Abstract

The invention relates to a special clamp for machining an NDT sample. The special clamp comprises a clamp body provided with a clamping opening, wherein a plane positioning point is arranged on one side of the clamping opening and comprises three plane positioning columns, and corresponding lock pillars are arranged on the other side of the clamping opening; one side of the clamp body is closely attached to a working platform of a numerical-control wire cutting machine, so that a plane determined by the three plane positioning columns is perpendicular to the working platform of the numerical-control wire cutting machine. According to the special clamp and method for machining the NDT sample, a plane part is used for positioning, so that clamping is easy, and the time is saved; and repeatedmeasurement and modification of a machining procedure are not needed, the NDT sample meeting design requirements can be machined accurately after one time of clamping, correction and positioning, theworking efficiency is improved under the premise that the quality is improved, and the machining cost is reduced.

Description

Technical field[0001]The invention relates to an NDT sample processing fixture, the processing technology field aimed at the existing NDT sample, and in particular to a special fixture for NDT sample processing and a processing method.Background technique[0002]In order to ensure the strength of the ship plate structure, it is necessary to use high-quality, good physical properties of steel plate as the hull plate. Among them, the NDT sample is used to test the physical properties of the ship plate. The processing accuracy of the NDT sample directly affects the ship plate. The results of research and development and the amount of steel produced. The test requirements are: take a sample of 130mm×50mm×20mm on the test ship plate, and no processing can be carried out around it. Then use a specific electrode according to the number to weld a 50mm×14mm×4.5mm surfacing on the specified surface. Finally, the middle part is processed until the design requirements are met, such asFigure 5 Sho...
