The processing technology of the annular groove is mainly milling. It can be processed with a milling cutter or a milling cutter head, or with a CNC machine tool. In many fields, there are many mechanical parts with deep hole annular grooves, such as the cylinder hole of the engine cylinder block, which needs to be processed with annular grooves at a deeper position in the hole, and then the processed annular grooves are measured to achieve the required length or shape.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a ring groove diameter gauge comprises an operating plate 1, an annular groove body 2 is arranged on the upper surface of the operating plate 1, a fixing clamp 14 is slidably connected to the upper surface of the operating plate 1, a fixing plate 15 is connected to the outer surface of the fixing clamp 14, and the fixing plates 15 are symmetrically distributed on the sides of the fixing clamp 14. There are two fixing clamps 14, and the inner surfaces of the fixing clamps 14 are arc-shaped, which can be well in contact with the outer surface of the annular groove body 2, thereby clamping the annular groove body 2.

[0024] An annular groove 3 is provided on the inner wall of the annular groove body 2, and a connecting block 16 is connected to the upper surface of the operating panel 1, and a stud 17 is rotatably connected to the outer surface of the connecting block 16, and the outer surface of the stud 17 is connected to the internal thread of the fixed plate 15, and there is a small ring in the middle of the stud 17, which divides the stud 17 into two parts. The thread directions of the two parts are opposite, so when the stud 17 is rotated, the two fixed plates 15 will approach each other, and a limiting plate 18 is connected to the upper surface of the operating panel 1, and a limiting groove 19 is provided on the bottom surface of the fixed plate 15, and the limiting plate 18 slides on the inner wall of the limiting groove 19, and the inner wall of the limiting groove 19 is coated with lubricating oil, which can reduce the friction between the limiting plate 18 and the limiting groove 19, and facilitate the limiting plate 18 to slide on the inner wall of the limiting groove 19.

[0025] The upper surface of the operating panel 1 is connected to a side panel 1 4, and the upper surface of the side panel 1 4 is connected to a telescopic rod 5, which is an electric telescopic rod 5 and can automatically extend and shorten. The top of the telescopic rod 5 is connected to a side panel 2 6, and the outer surface of the side panel 2 6 is connected to a top plate 7. A through groove 8 is provided on the upper surface of the top plate 7, and a separator 9 is connected to the inner wall of the through groove 8. The thickness of the separator 9 is extremely small and can be ignored.

[0026] The outer surface of the top plate 7 is slidably connected to a slider 10, the upper surface of the top plate 7 is connected to a protrusion 20, a groove 21 is provided on the bottom surface of the slider 10, and the protrusion 20 slides on the inner wall of the groove 21. The presence of the protrusion 20 can limit the movement of the slider 10, so that the slider 10 can only move horizontally along the direction of the protrusion 20.

[0027] The bottom surface of the slider 10 is connected to the long board 11, and the upper surface of the top plate 7 is connected to the ruler 22. There are two rulers 22. One end of the ruler 22 is aligned with the front side of the separator 9. When measuring, when the slider 10 moves a certain distance, the distance moved by the slider 10 can be directly read using the ruler 22. The long board 11 is made of a relatively hard material and is not easy to bend or deform.

[0028] The outer surface of the long plate 11 is slidably connected to the inner wall of the through groove 8. The outer surface of the long plate 11 is connected to a probe 12. There are two probes 12 in total. There is a probe 12 at the bottom end of each long plate 11. The upper surface of the slider 10 is connected to a push-pull handle 13. There are two fixing clips 14 in total. The center position between the two fixing clips 14 is the center position of the separator 9. When the stud 17 is rotated, the two fixing clips 14 will move the same distance. Therefore, when the annular groove body 2 is fixed, the center position of the annular groove body 2 is always located at the center position of the separator 9, and is located in the same vertical plane as the separator 9.

[0029] It should be noted that, in actual use of the device, when measuring, the annular groove body 2 is placed on the operating panel 1, and the two studs 17 are rotated at the same time, the two fixing clips 14 will approach each other at the same distance, the limit plate 18 will slide on the inner wall of the limit groove 19, and the annular groove body 2 will be fixed on the operating panel 1, and the center of the annular groove body 2 is located at the center position of the separator 9. After that, the telescopic rod 5 is started again, and the telescopic rod 5 drives the probe 12 to move downward through the side plate 2 6 and the top plate 7, so that the probe 12 enters the annular groove 3 in the annular groove body 2, and then the push-pull handle 13 is manually turned. At this time, the protrusion 20 slides on the inner wall of the groove 21, and the probe 12 contacts the inner wall of the annular groove 3. The distance moved by the slider 10 is observed by the ruler 22, and the diameter of the annular groove 3 can be calculated. Assuming that the width of the slider 10 is L, the length of the probe 12 is H, the distance moved by the slider 10 is S, and the diameter of the annular groove 3 is T, then T=2(L+H+S).
