[0020] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0021] like Figure 1-Figure 3As shown, the valve lock clamp image measurement and positioning device includes a lower base 3, an upper base 2 is provided on the upper end of the lower base 3, a fixed top 5 is provided on the upper base 2, the bottom end of the fixed top 5 passes through the upper base 2, a positioning structure is provided on the lower base 3, and the bottom end of the fixed top 5 is located above the positioning structure.

[0022] The positioning pin 6 and the card slot 11 positioning structure constitute the positioning structure of the valve lock clip 1, which provides a fixed position for the measurement and positioning of the valve lock clip 1. The sharp part 10 of the fixed tip 5 contacts the valve lock clip 1 to improve the positioning stability and prevent it from rotating. After the valve lock clip 1 is positioned by the above-mentioned positioning structure, the fixed tip 5 contacts the valve lock clip 1 to achieve its fixation. After fixation, the overall structure is placed on the workbench of the image measuring equipment, and the precise measurement of the conical surface size of the valve lock clip 1 can be achieved, thereby measuring the conical surface size of the valve lock clip 1.

[0023] like Figure 1 and Figure 2 As shown, the positioning structure includes a positioning pin 6, and a slot 11 is provided in the middle of the positioning pin 6; the positioning pin 6 is arranged horizontally, and a sharp portion 10 is provided at the bottom end of the fixing tip 5, and the slot 11 is located below the sharp portion 10. The outer side of the valve lock clamp 1 is a conical surface, and the inner side is a lock clamp groove. The valve lock clamp 1 is positioned and clamped by the positioning pin 6 and the slot 11, so as to realize the image measurement of the conical surface size; the slot 11 is adapted to the length of the valve lock clamp 1, and one side of the lock clamp groove on the valve lock clamp 1 contacts the slot 11, and the conical surface side of the valve lock clamp 1 faces outward. After the valve lock clamp 1 is fixed by the slot 11, the end of the sharp portion 10 contacts the valve lock clamp 1, that is, it is in the lock clamp groove positioning state, and the operator can measure the conical surface of the valve lock clamp 1 through the image measurement equipment; wherein, when the sharp portion 10 provides a fixing effect on the valve lock clamp 1, it will not cause excessive obstruction of the valve lock clamp 1, so that the operator can make a complete observation through the image measurement equipment.

[0024] like Figure 1 and Figure 3As shown, the valve lock clamp image measurement and positioning device also includes a positioning block 4, which is arranged on one side of the lower base 3. The positioning block 4 is provided with a positioning groove 12, which is a conical structure and extends to both ends of the positioning block 4. The conical surface of the valve lock clamp 1 is positioned by the positioning block 4 to achieve image measurement of the contour size of the lock clamp groove. The conical surface of the positioning groove 12 has the same taper as the conical surface of the valve lock clamp 1. When one side of the conical surface of the valve lock clamp 1 contacts the positioning groove 12, it is in an accurate positioning posture. At the same time, one side of the lock clamp groove faces upward, so that the conical surface positioning of the valve lock clamp 1 can be achieved, and the operator can measure the contour of the lock clamp groove through the image measurement of the contour meter. During the operation, since the positioning groove 12 extends to the end of the positioning block 4, the operator can directly push the valve lock clamp 1 along the positioning groove 12 to reach a suitable position, which facilitates the operation process. Furthermore, the positioning groove 12 is of a conical structure, and the width of the positioning groove 12 gradually increases from one end to the other end, which can adapt to the positioning of valve lock clips 1 of different specifications and has a wide range of applications.

[0025] like Figure 1 and Figure 2 As shown, a locking pin 7 is provided in the middle of the upper base 2, and the locking pin 7 presses and fixes the top 5. The locking pin 7 presses and fixes the top 5, so that the top 5 reaches a suitable position and lightly contacts the valve lock clamp 1, preventing the sharp portion 10 from causing damage to the valve lock clamp 1.

[0026] like Figure 1 As shown, a detent pin 8 is provided on one side of the upper base 2, and the detent pin 8 is arranged horizontally. A through hole 13 is provided on the fixed top 5, and the detent pin 8 passes through the upper base 2 and penetrates into the through hole 13. After the detent pin 8 is inserted into the through hole 13, the fixed top 5 can be prevented from rotating, thereby improving the stability of the fixed top 5.

[0027] like Figure 1 and Figure 2 As shown, a limiting step 9 is provided at the top of the fixed top 5. The limiting step 9 is larger than the diameter of the fixed top 5, so the limiting step 9 can prevent the fixed top 5 from passing through the upper base 2.

[0028] like Figure 1 As shown, the lower base 3 is provided with a mounting hole 14, the mounting hole 14 passes through one end of the lower base 3, and the positioning pin 6 is arranged in the mounting hole 14. The positioning pin 6 is cylindrical, and the replacement function is realized by inserting and removing from the mounting hole 14, and the resistance during the insertion and removal process is small. Therefore, by replacing the positioning pin 6 with the corresponding specification card slot 11, the valve lock clip 1 of different specifications can be clamped.

[0029] like Figure 1 and Figure 2 As shown, the upper base 2 and the lower base 3 are both U-shaped structures. The two bases are placed opposite to each other, and the opening formed by the U-shaped structures of the two bases serves as the positioning area of ​​the valve lock clamp 1. The structures of the two bases are simple and easy to process.

[0030] The positioning process is as follows: when measuring the conical surface size of the valve lock clip 1, insert the valve lock clip 1 into the card slot 11, with the conical surface side of the valve lock clip 1 facing outward, use the locking pin 7 to press the fixed top 5 until the end of the sharp part 10 gently contacts the fixed valve lock clip 1, and use the pin 8 to limit the rotation of the fixed top 5, and the valve lock clip 1 is positioned. Then put the device on the workbench of the image measuring equipment, and the image measuring equipment captures the image and transmits it to the computer screen, and then calculates and completes the measurement through software. When measuring the contour size of the lock clip groove of the valve lock clip 1, according to the specifications of the valve lock clip 1, push the valve lock clip 1 to the appropriate position on the positioning groove 12, so that the conical surface side of the valve lock clip 1 contacts the positioning groove 12, and the valve lock clip 1 is positioned, and then the contour of the lock clip groove is measured by the profilometer.

[0031] The valve lock clamp image measurement and positioning device realizes the image method precision measurement of the conical surface size and lock clamp groove profile size of the valve lock clamp 1 by positioning and fixing the positioning pin 6, the fixing top 5 and the positioning block 4, solves the problem that the valve lock clamp 1 is difficult to accurately position during image measurement, and ensures accurate measurement results. The device has a simple structure, low use cost, simple operation, fast measurement, and can be applied to the image measurement of valve lock clamps 1 of various specifications.

[0032] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
