[0058] As shown in the figure, Figure 4 The fixing assembly 3 comprises a bracket 31, an upper fixing block 33, a lower fixing block 32 and an adjusting screw 34 connected with the upper fixing block 33;

[0064] The longitudinal adjusting plate 6 is connected with the shell 41, and the longitudinal adjusting plate 6 is adapted to drive the shell 41 to move longitudinally in the moving plate 45.

[0065] The working principle of the embodiment is as follows:

[0066] In use, first the main body of the electric spindle is fixed in the fixed assembly 3, first the electric spindle is placed in the V-shaped groove of the lower fixed block 32, and then the adjusting screw two 34 is rotated by manual or electric control. The adjusting screw two 34 is in threaded connection with the support 31. When the adjusting screw two 34 is rotated, the upper fixed block 33 is driven to move longitudinally to contact the surface of the electric spindle and apply pressure. The lower fixed block 32 cooperates with the electric spindle to fix the electric spindle. It should be noted that the adjusting screw two 34 will not rotate the upper fixed block 33 when rotating, but only drive the upper fixed block 33 to move longitudinally. Bearings can be provided between the upper fixed block 33 and the adjusting screw two 34.

[0067] After the electric spindle is fixed, the tool or test rod is inserted and fixed, cooperates with the conical surface in the electric spindle and is fixed by a pneumatic way. This part belongs to the prior art. After the tool or test rod is fixed, the adjusting screw one 43 is rotated by manual or electric control, thereby driving the L-shaped plate 42 to move longitudinally, and further driving the micrometer 44 to move longitudinally. After continuous adjustment, the probe part of the micrometer 44 contacts the surface of the tool or test rod. After contact, the spindle is rotated, and whether the value of the micrometer 44 changes is observed to determine whether there is deviation when the tool is installed and rotated.

[0068] The driving motor 21 is started to drive the moving screw 22 to rotate. The moving screw 22 drives the moving plate 45 to move linearly under the rotation. The moving screw 22 and the moving plate 45 can be assembled by a ball nut. This part belongs to the prior art and will not be described in detail here. When the moving plate 45 is driven to move, the moving plate 45 drives the entire detection assembly one 4 to move, thereby realizing the linear movement of the micrometer 44. The stroke of the linear movement of the micrometer 44 is the length of the tool or test rod. During the linear movement of the micrometer 44, the value is observed to determine the parallelism of the tool after being installed on the electric spindle. When the parallelism deviation is large, it can be inferred that the conical surface of the electric spindle has a problem and needs to be further repaired to avoid affecting the machining precision.

[0069] The guide rod 5 is connected to the upper fixed block 33 and the shell 41 by the guide rod 5. When the detection component 1 4 is moved by the movable screw 22, the guide rod 5 is driven to slide in the upper fixed block 33. When the upper fixed block 33 is longitudinally adjusted by the adjusting screw 2 34, the shell 41 moves longitudinally inside the movable plate 45 through the longitudinal adjustment plate 6, and always maintains the synchronous movement between the shell 41 and the upper fixed block 33, ensuring that the movable screw 22 is more stable when driving the micrometer 44 to move horizontally, and can ensure that the relative position of the micrometer 44 and the spindle remains unchanged, which helps to perform accurate measurement and vibration detection at different positions of the spindle, thereby improving the accuracy of the detection. The design of the shell 41 following the movement of the upper fixed block 33 enables the test platform to more flexibly adapt to spindles of different sizes and types. By adjusting the height and position of the upper fixed block 33, spindles of different sizes can be conveniently clamped, and it is ensured that the detection component can be accurately aligned with the part to be detected.

[0070] The above is a static detection method. In addition, the electric spindle can be powered on through the power box 9. After the electric spindle is powered on, the rotating parts inside it start to rotate, thereby driving the tool or test rod installed on the electric spindle to start rotating. Before this, the micrometer 44 is pre-contacted with the surface of the tool or test rod, and slightly lifted up after contact. After the tool or test rod starts to rotate, the micrometer 44 is moved horizontally again by the moving screw 22 to detect whether the tool or test rod will jump due to vibration and other factors when it is highly rotated. The amount of lifting of the micrometer 44 can be set according to the allowable jump deviation. When the value of the jump deviation exceeds the set range, it will hit the micrometer 44, causing its degree to change.
