Slider 2 is slidably mounted on both support platforms 1. A connecting block 3 is provided on the top surface of the two sliders 2. An electric push rod 4 is slidably mounted on the connecting block 3. The connecting block 3 has a through-hole for mounting. Linear guide rails (not shown in the figure) are installed in both the support platforms 1 and the mounting groove. The sliders 2 and the electric push rod 4 cooperate with the linear guide rails to achieve sliding. An active scanning probe 5 is installed at the telescopic end of the electric push rod 4. The active scanning probe 5 is prior art, and its specific structure and working principle will not be described in detail here.

[0022] A square groove 8 is formed on the top surface of the placement platform 12. An electric push rod 16 is fixedly installed on the inner bottom surface of the square groove 8. A dual-axis slide cylinder 9 is fixedly installed at the telescopic end of the electric push rod 16. The telescopic movement of the electric push rod 16 can move the dual-axis slide cylinder 9, thereby adjusting the height of the dual-axis slide cylinder 9. The telescopic end of the dual-axis slide cylinder 9 is connected to a support block 10. One support block 10 is equipped with a clamping block 14, and the other support block 10 is equipped with a limit block 15. The telescopic movement of the dual-axis slide cylinder 9 can adjust the distance between the two support blocks 10. When it is necessary to fix or support the mechanical parts to be tested, the structures installed on the two support blocks 10 are the same. For example, when it is necessary to support the cylindrical mechanical parts, clamping blocks 14 are installed on both support blocks 10. When it is necessary to limit the mechanical parts, limit blocks 15 are installed on both support blocks 10.

[0023] The top surface of the support block 10 is provided with a clamping groove 13, and the top surface of the support block 10 is provided with a sealing plate 7, the size of the sealing plate 7 matches the square groove 8, and the bottom end of the sealing plate 7 is clamped with the clamping groove 13. When the mechanical parts do not need to be supported or limited, the square groove 8 is blocked by the sealing plate 7, and the top surface of the sealing plate 7 is flush with the top surface of the placement platform 12, and when the mechanical parts need to be supported or limited, the sealing plate 7 is removed, and the clamping block 14 and the limiting block 15 are supported or limited. When measuring, the height difference between the bottom surface of the clamping block 14 and the top surface of the square plate 17 and the placement platform 12 can be measured by the prior art, which will not be described in detail here.

[0025] The side of the clamping block 14 facing the limiting block 15 is arc-shaped, and the arc-shaped area is less than one-fourth of the area of a circle, so as to adapt to the support of mechanical parts of various specifications of circular pipes, and the surfaces of the clamping block 14 and the limiting block 15 are pasted with rubber blocks, so as to increase the friction.

[0026] The two side inner walls of the square groove 8 are respectively provided with grooves 11, one of the grooves 11 has a length greater than that of the other groove 11, and the square plate 17 is slidably arranged in the groove 11. The length of the square plate 17 is greater than the width of the square groove 8, and the surface of the square plate 17 and the side surface of the sealing plate 7 are provided with a pushing groove. The mechanical parts can also be placed on the square plate 17 for detection, and the applicability is further improved through the cooperation between the square plate 17 and the electric push rod two 16. When in use, the square plate 17 is pulled out from one groove 11 and located in the other groove 11, and when not in use, it is located in one groove 11.

[0027] In work, the double-shaft sliding table air cylinder 9 can be driven by the electric push rod two 16 to move upward, so that the support blocks 10 connected at both ends of the double-shaft sliding table air cylinder 9 move upward, the clamping block 14 and the limiting block 15 can be fixed on the support blocks 10, the clamping block 14 can support the mechanical parts of circular pipes, and the limiting block 15 can limit the mechanical parts during detection. Since the height of the support block 10 is adjustable, the height of the clamping block 14 and the limiting block 15 can also be adjusted according to actual needs, and the applicability is stronger.
