[0026] like Figure 1-4 As shown in the figure, the utility model proposes a quick replacement mechanism for the function of a composite trigger probe and a visual probe, including a rotation switching mechanism 3 for rotating and switching the trigger probe 11 and the visual probe 12. The rotation switching mechanism 3 includes a main shaft 30, a top ring 31, a guide rod 32, a spring 33, a connecting ring 34, a key bar 35 and a key slot 36. The main shaft 30 is fixed to an external fixing part such as a scanner body. The top ring 31 is Figure 2The method shown is rotatably engaged with the top of the main shaft 30. The connecting ring 34 is movably engaged with the main shaft 30, and a pair of key bars 35 are fixedly connected to the outer ring surface of the main shaft 30, and a key slot 36 that can be vertically slidably connected to the key bar 35 is provided on the inner ring surface of the connecting ring 34. The vertical sliding between the key bar 35 and the key slot 36 can ensure that the connecting ring 34 can slide vertically without self-rotation. At least one guide rod 32 is provided, the top end of which is fixedly connected to the lower surface of the top ring 31, and the bottom end of which is movably penetrated through the connecting ring 34, for providing guidance for the vertical movement of the connecting ring 34. In addition, the spring 33 is movably engaged with the guide rod 32, and the top end of the spring 33 is fixedly connected to the lower surface of the top ring 31, and the bottom end of the spring 33 is fixedly connected to the upper surface of the connecting ring 34, and the elastic tension of the spring 33 prevents the key slot 36 from sliding out of the key bar 35.

[0027] Furthermore, the quick-change mechanism further includes two sets of probe fixing assemblies 2 for installing the trigger probe 11 and the visual probe 12 respectively, and the probe fixing assembly 2 includes a fixing seat 21, a clamp 22 and a connecting arm 23. The clamp 22 is fixed on the fixing seat 21 for installing the trigger probe 11 or the visual probe 12. One end of the connecting arm 23 is fixedly connected to the fixing seat 21, and the other end is fixedly connected to the outer annular surface of the connecting ring 34.

[0028] The quick change mechanism also includes a height adjustment mechanism 4 for adjusting the detection height when switching the trigger probe 11 and the visual probe 12. A pair of height adjustment mechanisms 4 are provided to adjust the height of the trigger probe 11 and the visual probe 12 respectively. The height adjustment mechanism 4 includes a fixed horizontal plate 41, a height adjustment plate 42, a push-pull member 43, a push rod 44, a connecting column 45, a threaded shaft 46, a threaded shaft sleeve seat 47 and a guide shaft sleeve seat 48. One end of the fixed horizontal plate 41, the threaded shaft sleeve seat 47 and the guide shaft sleeve seat 48 are all fixed to the external fixing member. The height adjustment plate 42 is an arc-shaped structure, the top end of which is rotatably connected to the fixed horizontal plate 41, and the other end is rotatably connected to the push-pull member 43. When the push-pull member 43 moves up and down, the height adjustment plate 42 can be rotated and tilted. The bottom end of the connecting column 45 is fixedly connected to the upper surface of the push-pull member 43, and the top end of the connecting column 45 is rotatably connected to the bottom end of the threaded shaft 46. In addition, the connecting column 45 movably penetrates the guide shaft sleeve seat 48, and the threaded shaft 46 is threadedly engaged with the threaded shaft sleeve seat 47. Therefore, when the threaded shaft 46 is rotated, the threaded engagement between it and the threaded shaft sleeve seat 47 is used to achieve lifting and lowering, and then the connecting column 45 drives the push-pull member 43 to lift and lower, so as to adjust the inclination angle of the height adjustment plate 42. At different inclination angles, the push rod 44 will be pushed downward by different distances, thereby adjusting the visual probe 12 to different detection heights.

[0029] The working principle of this embodiment is as follows: when it is necessary to switch the positions of the trigger probe 11 and the visual probe 12 (to Figure 1 The position in the switch is Figure 4 As shown in the figure, first hold the connecting ring 34 and move it downward, so that the key bar 35 slides out of the key slot 36 to release the rotation restriction of the connecting ring 34, and then rotate the connecting ring 34 180° with the main shaft 30 as the axis, that is, the trigger probe 11 and the visual probe 12 are exchanged. When the rotation adjustment is completed, hold the connecting ring 34 and move it upward, so that the key bar 35 is re-engaged in the key slot 36 to limit the rotation of the connecting ring 34, and the tension provided by the spring 33 will ensure that the key bar 35 will not slide out of the key slot 36;

[0030] At the same time, when the visual probe 12 is rotated to Figure 4 When the position is shown, the top end of the push rod 44 installed thereon contacts the height adjustment plate 42 and is pushed downward in the reverse direction, thereby adjusting the height of the visual probe 12 installed on the probe fixing assembly 2. Figure 3 The inclination angle of the height adjustment plate 42 can be adjusted by rotating the threaded shaft 46. At different inclination angles, the push rod 44 will be pushed downward to different distances, thereby adjusting the visual probe 12 to different detection heights. Figure 1 In the position shown, the trigger probe 11 contacts the corresponding height adjustment plate 42, and the detection height is adjusted accordingly. This design combines the position switching and height adjustment of the trigger probe 11 and the visual probe 12 into one action, which greatly improves the switching efficiency.

[0031] In summary, through the design of the rotary switching mechanism 3, the positions of the trigger probe 11 and the visual probe 12 can be quickly switched by horizontal rotation; through the design of the height adjustment mechanism 4, the heights of the trigger probe 11 and the visual probe 12 can be quickly adjusted to adapt to different detection heights, and the height adjustment is automatically performed under the horizontal rotation of the rotary switching mechanism 3 to achieve rapid switching and height adjustment of the trigger probe 11 and the visual probe 12.

[0032] The above-mentioned specific embodiments are only several optional embodiments of the present invention.
