After the spindle of the CNC machine tool is assembled, the spindle assembly detection equipment for the CNC machine tool is used to detect the data after the spindle assembly to see whether it meets the assembly standard. After the base plate 1 is placed directly below the assembled spindle, the laser lamp 17 is activated to emit laser light, so that the laser is irradiated on the spindle, and the position of the sliding block 10 is adjusted by adjusting the movement of the component. The guide assembly is used to guide the sliding block 10 so that the sliding block 10 moves smoothly. When the sliding block 10 moves, the indicator plate 12 is driven to move, and the laser light 17 is driven to move. The position of the detected spindle can be determined by the location irradiated by the laser light 17. At the same time, the length of the assembled spindle can be measured by observing the position of the indicator plate 12 on the scale 6, thereby achieving the purpose of facilitating the measurement of the length of the assembled spindle and improving the measurement efficiency. After the sliding block 10 is moved to one end of the spindle, the driving assembly is located below the spindle, and the position of the driving assembly is adjusted so that the driving assembly The component fits with the bottom of the main shaft, thereby causing the main shaft to rotate.

When the sliding block 10 moves, the concave frame 15 will be driven to move. When the concave frame 15 moves, the rotating wheel 16 will be driven to rotate inside the sliding groove 46, thereby assisting the sliding block 10 to move smoothly.

A driving motor 22 is fixedly installed inside the movable groove 14, and one end of the adjusting screw 21 is fixedly connected to the output end of the driving motor 22. A limiting assembly is arranged inside the movable groove 14. When the position of the support block 19 is adjusted, the driving motor 22 is operated to drive the adjusting screw 21 to rotate. When the adjusting screw 21 rotates, the threaded barrel 20 will move.

The position of the retracting plate 32 and the extension plate 35 can be adjusted by adjusting the position of the support block 19, so that the top of the retracting plate 32 and the extension plate 35 can contact the bottom of the main shaft. After the limit bolt 42 is rotated to separate the limit bolt 42 from the threaded hole 41 and the limit bolt 42 is pulled out, the retracting plate 32 and the extension plate 35 are no longer limited. Then, when the main shaft rotates, when the main shaft is eccentric, the retracting plate 32 is moved downward and the extension plate 35 is moved upward by contacting the cylinder 44.

When the main shaft rotates eccentrically, pressure is applied to the top of the retracting plate 32, and the downward movement of the retracting plate 32 will drive the first contact piece 33 to contact the first conductive piece 28, and then the current inside the battery 27 will flow into the first warning light 30, so that the first warning light 30 works and lights up. When the extension plate 35 moves upward, it will drive the second contact piece 36 to contact the second conductive piece 29, and then the current inside the battery 27 will flow into the second warning light 31, so that the second warning light 31 works and lights up.

[0050] Working principle: first, after the spindle of the CNC machine tool is assembled, the spindle assembly detection equipment used for the CNC machine tool is used to detect the data after the spindle is assembled to see whether it meets the assembly standards. After the base plate 1 is placed directly below the assembled spindle, the laser lamp 17 is activated to emit laser light. The laser lamp 17 is electrically connected to the battery assembly 3, so that the laser is irradiated on the spindle. The servo motor 8 is activated to drive the threaded screw 9 to rotate. When the threaded screw 9 rotates, the threaded ring 11 moves. When the threaded ring 11 moves, the sliding block 10 moves, and then the indicator plate 12 moves. When the sliding block 10 moves, The concave frame 15 is driven to move. When the concave frame 15 moves, it drives the rotating wheel 16 to rotate inside the sliding groove 46, thereby assisting the sliding block 10 to move smoothly, and at the same time drives the laser light 17 to move. The position of the detected spindle can be determined by the location irradiated by the laser light 17. At the same time, by observing the position of the indicator plate 12 on the scale 6, the length of the assembled spindle can be measured, thereby achieving the purpose of facilitating the measurement of the length of the assembled spindle and improving the measurement efficiency. After the sliding block 10 is moved to one end of the spindle, the top ends of the retracting plate 32 and the extending plate 35 are in contact with the bottom of the spindle, and the rotating wheel 17 is driven to move. The limit bolt 42 is moved to separate the limit bolt 42 from the threaded hole 41. After the limit bolt 42 is pulled out, the retraction plate 32 and the extension plate 35 are no longer limited. Then, when the main shaft rotates, when the main shaft is eccentric, the retraction plate 32 is moved downward and the extension plate 35 is moved upward by contacting the cylinder 44. The downward movement of the retraction plate 32 will drive the first contact piece 33 to contact the first conductive piece 28, and then the current inside the battery 27 will flow into the first warning light 30, so that the first warning light 30 works and lights up. When the extension plate 35 moves upward, it will drive the second contact piece 33 to contact the first conductive piece 28. The sheet 36 contacts the No. 2 conductive sheet 29, and then the current in the battery 27 flows into the No. 2 warning light 31, causing the No. 2 warning light 31 to light up. The eccentricity direction of the main shaft can be determined through the working status of the No. 1 warning light 30 and the No. 2 warning light 31, which makes it easier for the staff to make adjustments. The working status of the warning component can be used to determine whether the main shaft is assembled accurately. The cleaning block 13 is fitted with the scale 6. When the indicator plate 12 moves and drives the scale 6 to move, the impurities adsorbed on the scale 6 can be removed through the cleaning block 13, and the scale 6 can be automatically cleaned.
