The drive motor is connected to the lead screw, and the lead screw nut is mounted on the lead screw. The drive motor drives the lead screw to rotate, so that the lead screw nut moves along the lead screw and cooperates with the slider and the slide rail to achieve sliding.

[0024] And take the X-axis drive mechanism 14 as an example, the X-axis drive mechanism 14 includes an X-axis drive motor 17, an X-axis lead screw (not shown in the figure), an X-axis lead screw nut (not shown in the figure), an X-axis slide rail 18, and an X-axis slider 19. The X-axis drive motor 17 is installed on the detection table 1, the X-axis drive motor 17 is connected to the X-axis lead screw, the X-axis lead screw nut is installed on the X-axis lead screw, the X-axis drive motor 17 drives the X-axis lead screw to rotate, so that the X-axis lead screw nut moves along the X-axis lead screw, the X-axis slider 19 is connected to the X-axis lead screw nut, and both ends of the X-axis slider 19 are slidably connected to the X-axis slide rail 18. The Y-axis drive mechanism 15 is assembled on the X-axis slider 19, so that the Y-axis drive mechanism 15 moves along the X-axis direction through the cooperation of the X-axis slider 19 and the X-axis slide rail 18;

[0025] The connection structures of the Y-axis driving mechanism 15 and the Z-axis driving mechanism 16 are the same as those of the X-axis driving mechanism 14 . The only difference is that they are assembled on different sliders to achieve movement in different directions. Therefore, they will not be described in detail.

[0026] The adsorption mechanism 6 includes a connecting rod 20 and a connecting plate 21.

The top surface of the auxiliary seat body 29 is a V-shaped surface, so that the alloy piece 2 to be tested can be placed on the auxiliary seat body 29 to prevent it from falling during transportation; there is a height difference between the two V-shaped surfaces at the top of the auxiliary seat body 29, which can prevent the cylindrical alloy piece 2 to be tested from tipping over; symmetrical slots 30 are provided on both sides of the top surface of the auxiliary seat body 29, and insert plates 31 are inserted into the slots 30 on both sides. The insert plates 31 can be inserted into different slots 30 to better adapt to alloy pieces 2 to be tested of different models and sizes, so as to facilitate better adsorption by the adsorption mechanism 6.

[0028] Figures 1 to 5 This is a structural diagram of the first embodiment. In this case, the spectrometer 8 is fixedly mounted on the fixing frame 7 .

[0029] In addition, a safety mechanism and an indicator light are installed on the fixed frame 7, and the safety mechanism and the indicator light are connected to the control mechanism; the safety mechanism can adopt a safety switch, and the safety mechanism is used to detect the fitting gap value between the alloy part 2 to be tested and the spectrometer 8, and feed it back to the control mechanism. If the fitting gap value is greater than the gap threshold, the control mechanism controls the indicator light to go out, and controls the current alloy part to be tested to re-perform the alloy composition detection operation. That is to say, if the alloy part 2 to be tested and the spectrometer 8 are not well fitted, the control mechanism will control the three-axis mechanism to move in an array form, replace the spectrometer 8 to the fitting detection point on the alloy part 2 to be tested, and then the spectrometer 8 and the current alloy part to be tested 2 will be detected again until the fitting gap value is not greater than the gap threshold, then the spectrometer 8 can detect the effective alloy composition data.

[0030] Example 2

[0031] When the alloy workpiece 2 to be tested is moved to the spectrometer 8 by the three-axis mechanism 4 for alloy composition detection, the upper and lower surfaces of the alloy workpiece 2 to be tested cannot be kept parallel during the grinding process, and there is a tilt, which causes the spectrometer 8 and the alloy workpiece 2 to be tested to not fit together, so the detection data of the spectrometer 8 will be inaccurate. Figure 6 As shown, an adaptive mechanism is provided on the fixing frame 7, and the adaptive mechanism includes two support seats 32. The spectrometer 8 is mounted between the two support seats 32. Upper and lower corresponding fixing columns 33 are installed on the bottom surface of the support seat 32 and the fixing frame 7. A second spring 34 is connected between the upper and lower corresponding fixing columns 33. When the alloy composition is detected, the spectrometer 8 will generate an adaptive force through the action of the second spring 34, so the spectrometer 8 and the alloy part 2 to be tested will be more closely fitted for detection, thereby improving the accuracy of data detection.

[0032] The working principle of the present invention is that, according to the different models and sizes of the alloy parts 2 to be tested, the inserting plate 31 is inserted into different card slots 30, and then the alloy parts 2 to be tested are placed on the V-shaped surface of the auxiliary seat body 29 and transported by the conveyor belt 28. A sensor (not shown in the figure) connected to the control mechanism can be set at a specific position of the detection table 1 to sense the presence of the alloy parts 2 to be tested. Once the alloy parts 2 to be tested are sensed, the control mechanism controls the three-axis mechanism 4 to move, and causes the adsorption mechanism 6 to adsorb the alloy parts on the auxiliary seat body 29 at a specific position. The alloy piece 2 to be tested, at this time, the conveyor belt 28 stops conveying, and then the three-axis mechanism 4 first sends the alloy piece 2 to the position of the first stroke collection piece 9. When the alloy piece 2 to be tested hits the spring piece 35 of the first stroke collection piece 9, the thickness value of the alloy piece 2 to be tested can be determined. Then the alloy piece 2 to be tested is moved to the position of the second stroke collection piece 10. When the alloy piece 2 to be tested hits the spring piece 36 of the second stroke collection piece 10, the diameter of the alloy piece 2 to be tested can be determined. Then, after the control mechanism receives the thickness information and diameter information of the alloy piece 2 to be tested, it is determined. After the size of the alloy piece 2 to be tested is determined, the control mechanism generates the travel of the alloy pieces 2 to be tested of different sizes to be accurately transported to the spectrometer 8 through the existing internal algorithm according to the determined size, and then controls the three-axis mechanism 4 to accurately transport the alloy piece 2 to be tested to the spectrometer 8 for alloy composition detection, that is, to prevent the alloy piece 2 to be tested from being too tightly pressed on the spectrometer 8, and to prevent the alloy piece 2 to be tested from not being able to contact the spectrometer 8, so that it can be completely fitted with the spectrometer 8 according to different sizes. Finally, after the detection is completed, the three-axis mechanism 4 will adsorb the adsorption mechanism 6 (that is, the adsorption mechanism 6) of the alloy piece 2 to be tested. The adsorption seat 23) returns to the initial position, and the alloy piece 2 to be tested is still placed on the auxiliary seat body 29. At this time, the conveyor belt 28 continues to move to transport and output. In addition, the patent can use multiple alloy composition detection mechanisms in conjunction with each other to realize flow operation, and can also realize multiple detections of the alloy piece 2 to be tested; and the alloy pieces 2 to be tested of other models and sizes are repeated according to the above-mentioned action principle, so that they can automatically adapt to the detection of aluminum alloy pieces of different models and sizes, with good versatility, and no need to purchase expensive detection equipment, low detection cost, easy operation, and low labor intensity.

[0033] The diameter or thickness information of the alloy part 2 to be tested is collected by the stroke collection part, which is an existing collection method. The collection of the thickness of the alloy part 2 to be tested is used as an example. When the alloy part 2 to be tested is not adsorbed, the adsorption seat 23 moves to contact the spring piece of the stroke collection part, and a stroke parameter (a constant value) can be obtained. When the alloy part 2 to be tested is adsorbed, the alloy part 2 to be tested moves to contact the spring piece of the stroke collection part, and another stroke parameter can be obtained. The difference between the two stroke parameters is the thickness of the alloy part 2 to be tested.
