[0012] The utility model has at least the following beneficial effects:

[0013] 1. As the screw rotates, the slider moves along the length of the screw, allowing the slider to slide and move along the slide groove, facilitating the synchronous displacement of the slider and the clip. The ejector pin and pointer on the end wall of the clip also move synchronously. The two ejector pins are close together and are used to clamp on the groove end wall of the screw. The groove diameter of the screw is obtained by identifying the scale mark on the pointer.

[0014] 2. The material holder and the stand are combined together by snapping together to form an integral body. When in use, the material holder can be easily disassembled and assembled. The material holder and the material cavity can be of various sizes, mainly to match the size of the material cavity with the screw part to be tested. The material cavity of the material holder is used to clamp the screw part, which is convenient for quick access to the screw part and groove diameter detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] See also Figure 1-4 The present invention provides a technical solution for a roller screw groove diameter detection device:

[0023] Example 1:

[0024] like Figure 1-4As shown, a roller screw groove diameter detection device includes a stand 1, a slide groove 2 is penetrated in the middle of the stand 1, a slider 3 is installed on the inner side of the slide groove 2, a screw 4 rotatably connected to the stand 1 is penetrated in the middle of the slider 3, a clip 5 is installed on the left side of the slider 3, a thimble 6 and a pointer 7 are arranged on the side end of the clip 5, a wrapping piece 8 is arranged on the left side of the upper and lower ends of the stand 1, a scale mark 9 is opened on the end wall of the stand 1, a material seat 10 is installed on the left side of the middle of the stand 1, a buckle 11 is installed on the end wall of the material seat 10, and a material cavity 12 is opened on the left end wall of the material seat 10.

[0025] Example 2:

[0026] Based on the first embodiment, Figure 1 and Figure 2 As shown, the stand 1 forms a sliding structure through the slide groove 2 and the slider 3, and the slider 3 is threadedly connected to the screw rod 4. There are two sliders 3. At the same time, the slider 3 is fixedly connected to the clamping piece 5, and the clamping piece 5 is fixedly connected to the ejector pin 6 and the pointer 7. When the screw rod 4 rotates, the slider 3 moves along the length direction of the screw rod 4, allowing the slider 3 to slide and move along the slide groove 2, facilitating the synchronous displacement of the slider 3 and the clamping piece 5. The ejector pin 6 and the pointer 7 on the end wall of the clamping piece 5 are synchronously displaced. The two ejector pins 6 are close to each other and are used to be stuck at the groove diameter end wall of the screw member. The groove diameter of the screw is obtained by identifying the scale mark 9 at the pointer 7.

[0027] Based on the first embodiment, Figure 3 and Figure 4 As shown, the stand 1 and the bag 8 are fixedly connected, the stand 1 and the material base 10 are fixedly connected, and the material base 10 is clamped to the stand 1 through the buckle 11. The material base 10 and the stand 1 are combined together through the buckle 11 to form a whole. When in use, it is convenient to disassemble and assemble the material base 10. The material base 10 and the material cavity 12 can be of various sizes, mainly the material cavity 12 is adapted to the size of the screw part to be detected. The material cavity 12 of the material base 10 is used to clamp the screw part, which is convenient for quick retrieval of the screw part and groove diameter detection.

[0028] Working principle: Through the rotation of the screw rod 4, the slider 3 is displaced along the length direction of the screw rod 4, allowing the slider 3 to slide and displace along the slide groove 2, which facilitates the synchronous displacement of the slider 3 and the clip 5, and the synchronous displacement of the ejector pin 6 and the pointer 7 on the end wall of the clip 5. The two ejector pins 6 are close to each other and are used to be clamped at the groove diameter end wall of the screw part. By identifying the scale mark 9 at the pointer 7, the groove diameter of the screw is obtained. The material base 10 and the stand 1 are combined together through the buckle 11 to form a whole. When in use, it is convenient to disassemble and assemble the material base 10. The material base 10 and the material cavity 12 can be of various sizes, mainly because the material cavity 12 is adapted to the size of the screw part to be detected. The material cavity 12 of the material base 10 is used to clamp the screw part, which facilitates the rapid retrieval of the screw part and the groove diameter detection.
