Description

Technical Field

[0001] The utility model relates to a calibration device, specifically a thread plug gauge calibration device, belonging to the technical field of thread plug gauges. Background Technique

[0002] A thread plug gauge is a tool used to measure the correctness of internal thread dimensions. It mainly has three types: ordinary coarse thread, fine thread and pipe thread. The types and designs of thread plug gauges depend on the accuracy requirements and pitch sizes of their applications. Thread plug gauges are also called thread gauges. According to the different internal and external threads to be inspected, they are divided into thread plug gauges and thread ring gauges.

[0003] After retrieval, the special thread plug gauge disclosed in the Chinese patent with the publication number CN211651415U includes a plug gauge body for inspecting internal threads with a surface galvanized tolerance grade of 6H. The plug gauge body is characterized in that it includes a go gauge body and a no-go gauge body with different tolerance zone positions. The go gauge body adopts 6H, and the no-go gauge body adopts 6G. One end of the plug gauge body of the utility model is 6H go, and the other end is 6G no-go, which can not only ensure the product quality, but also make the inspection of the plug gauge body of the utility model convenient, fast and not easy to make mistakes.

[0004] Although the inspection of the plug gauge body in the above scheme is convenient, fast and not easy to make mistakes, the thread plug gauge in the above patent is difficult to detect and calibrate the plug gauge body itself. During long-term use, the threads of the plug gauge body itself will wear, affecting the detection accuracy of the plug gauge body. Therefore, we provide a thread plug gauge calibration device to solve the above problems. Content of the Utility Model

[0025] The embodiments of the present utility model provide a thread plug gauge calibration device.

[0026] Please refer to Figure 1 and Figure 2, including a microscope body 1 and a support detection platform 2. The microscope body 1 is a prior art and will not be elaborated much. The microscope body 1 is directly above the center point of the support detection platform 2. One side of the support detection platform 2 is fixedly connected to one side of the first L-shaped support frame 3. The top of the first L-shaped support frame 3 is rotatably connected to the bottom of the linkage curve plate 4. The setting of the first L-shaped support frame 3 can ensure that the linkage curve plate 4 rotates with the joint with the first L-shaped support frame 3 as the origin, thereby ensuring the movement of other components.

[0027] Please refer to Figure 2 , there are four groups of linkage curve plates 4 in total. Rubber positioning posts 5 are rotatably arranged in the grooves on one side of the four groups of linkage curve plates 4. There are four groups of rubber positioning posts 5 in total. Rubber positioning posts 5 are rotatably arranged in the grooves on one side of the linkage curve plate 4. The setting of multiple groups of linkage curve plates 4 and multiple groups of rubber positioning posts 5 can comprehensively push the plug gauge body to move, so that the plug gauge body is directly below the microscope body 1, achieving the effect of direct alignment.

[0028] Please refer to Figure 3 , the bottom of the linkage curve plate 4 is fixedly connected to the top of the first linkage plate 6. The bottom of the first linkage plate 6 is rotatably connected to the top of the second linkage plate 7. One end of the second linkage plate 7 is rotatably connected to one side of the linkage control slider 8. The cooperation among the first linkage plate 6, the second linkage plate 7 and the linkage control slider 8 can effectively ensure the linkage effect, thereby achieving the expected movement effect.

[0029] Please refer to Figure 3 , the other side of the linkage control slider 8 is rotatably connected to one end of the third linkage plate 9. The bottom of the third linkage plate 9 is rotatably connected to the top of the drive control disk 10. The cooperation among the linkage control slider 8, the third linkage plate 9 and the drive control disk 10 ensures the directional output of force, thereby ensuring the movement of subsequent components and not easily causing jamming.

[0030] Please refer to Figure 4 , the bottom of the drive control disk 10 is fixedly connected to the output rotating shaft of the unidirectional DC motor 11. The unidirectional DC motor 11 is fixedly arranged in the middle of the support balance plate 13. The unidirectional DC motor 11 is a prior art and will not be elaborated much. The setting of the unidirectional DC motor 11 can effectively provide sufficient power support for the movement of subsequent components, thereby ensuring the normal operation of this calibration device.

[0031] Please refer to Figure 1The bottom of the supporting balance plate 13 is fixedly connected to the top of the supporting working base plate 14, the top of the supporting working base plate 14 is fixedly connected to the bottom of the second L-shaped supporting frame 16, and the groove on the top of the second L-shaped supporting frame 16 is fixedly provided with a microscope body 1. The microscope body 1 is a prior art and will not be described in detail. The setting of the microscope body 1 can accurately observe the threads of smaller thread plug gauges for convenient detection.

[0032] See also Figure 1 The bottom of the supporting working base 14 is fixedly connected to the top of the supporting working base 15. There are four groups of supporting working bases 15. The four groups of supporting working bases 15 are evenly distributed at the bottom of the supporting working base 14. The setting of multiple groups of supporting working bases 15 can effectively ensure the overall stability of the calibration device and is not prone to tilting.

[0033] See also Figure 3 and Figure 4 A positioning guide single rod 12 is fixedly arranged in the groove in the middle of the supporting balance plate 13. There are two groups of positioning guide single rods 12. The outer circumferential surfaces of the two groups of positioning guide single rods 12 are respectively slidably provided with linkage positioning sliders 8. The setting of multiple groups of positioning guide single rods 12 can effectively ensure the sliding direction of the linkage positioning slider 8, thereby driving the subsequent components to move, making the calibration device components work more precisely, and driving the bottom of the positioning disc 10 to be rotatably connected with the top of the supporting balance plate 13.

[0034] Working principle: first, place the thread plug gauge on the support detection platform 2, start the unidirectional DC motor 11 to work, drive the driving position control disk 10 to rotate on the support balance plate 13, pull the third linkage plate 9 to move, and make the linkage position control slider 8 move horizontally on the position control guide single rod 12. At the same time, the movement of the linkage position control slider 8 will also drive the second linkage plate 7 to move, thereby pulling the first linkage plate 6 to move accordingly, so that the linkage curve plate 4 starts to move, so that the rubber positioning column 5 starts to shrink inward, support the thread plug gauge, and move the thread plug gauge toward the center point of the support detection platform 2. When the thread plug gauge reaches the center point of the support detection platform 2, the rubber positioning column 5 is stationary, realizing the clamping effect of the rubber positioning column 5 on the thread plug gauge. At this time, the thread plug gauge is directly below the microscope body 1, so that the microscope body 1 can directly perform detection and calibration operations.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model.
