Description

Technical Field

[0001] The utility model relates to a thread concentricity inspection tool, belonging to the inspection field. Background Art

[0002] The existing technology detects the concentricity of the thread by using a thread scanner, which takes a long time to detect and has complicated detection steps, making it unsuitable for batch detection. Since the detection requires manual real-time detection next to the machine, it not only reduces the detection rate but also increases the labor cost. Utility Model Content

[0003] In order to overcome the defects of the prior art, the utility model provides a thread concentricity inspection tool. The technical solution of the utility model is:

[0004] A thread concentricity inspection tool comprises a thread detection shaft, a reference block and a main body. The reference block is arranged at one end of the main body, the reference block is arranged coaxially with the main body, and is arranged in a stepped manner with the main body; the thread detection shaft is arranged in a horizontal direction, installed on the reference block, and is arranged coaxially with the reference block.

[0005] The thread detection shaft, the reference block and the main body are integrally formed.

[0006] The advantages of the utility model are as follows: the thread detection shaft, reference block and main body are made of tungsten steel. Due to the wear resistance of tungsten steel, the service life of the inspection tool is long, saving processing costs. The inspection tool adopts high-precision thread grinding machine tools and cylindrical grinding machine tools, the accuracy of the inspection tool is guaranteed, and the detection data is more accurate. And because the inspection tool is light, the inspection tool meets the portability requirements, which can facilitate real-time measurement in the production workshop. In addition, this inspection tool can meet the inspection needs of batch workpieces. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 It is a schematic diagram of the main structure of the utility model. DETAILED DESCRIPTION

[0008] The present invention is further described below in conjunction with specific embodiments, and the advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are merely exemplary and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements fall within the scope of protection of the present invention.

[0009] See also Figure 1The utility model relates to a thread concentricity inspection tool, comprising a thread detection shaft 1, a reference block 2 and a main body 3. The reference block 2 is arranged at one end of the main body 3, and the reference block 2 is coaxially arranged with the main body 3 and arranged in a stepped manner with the main body 3; the thread detection shaft 1 is arranged in a horizontal direction, mounted on the reference block 2, and coaxially arranged with the reference block 2. The thread detection shaft 1, the reference block 2 and the main body 3 are integrally formed.

[0010] The working principle of the utility model is: the thread detection shaft 1 of the utility model is screwed into the thread of the workpiece to be tested, and the stop reference block 2 can enter the workpiece hole, then the concentricity of the workpiece thread is qualified, otherwise it is unqualified.

[0011] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
