please refer to fig. 9: firstly, before testing the spindle 1, the dial indicator 410 is far away from the spindle 1, and secondly, the locking plate 14 is not contacted with the rubber plates 11 at the two sides.
Please refer to fig. 9 and 10: when the spindle 1 is tested, a user needs to slide the lifting frame 12 upwards along the vertical direction of the limiting frame 10, pulleys 13 on two sides of the lifting frame 12 roll on the inner wall of the truss 9 in the sliding process to ensure the lifting stability of the lifting frame 12, when the front end of the dial indicator 410 moves to the position of the spindle 1, then the user needs to rotate the locking plate 14 by ninety degrees, and at the moment, friction damping is formed between two sides of the locking plate 14 and the rubber plate 11 to position the lifting frame 12 at the position;
when spindle 1 is tested, spindle 1 is started to rotate, if polarization occurs on the rotating spindle 1, the rotating spindle 1 collides with dial indicator 410, a user can judge the polarization of spindle 1 by looking at pointer swing on dial indicator 410, if swing is large, the polarization is large, and if swing is small, the polarization is small.
The trigger mechanism 5 is including setting firmly in mounting panel 3 upper surface and being located the second locating plate 51 of first locating plate 41 one side, the inside sliding connection of second locating plate 51 has second slider 52, the top of second slider 52 has set firmly second collar 53, the outer wall of second collar 53 has set firmly the joint board 54, the upper surface rotation of joint board 54 is connected with the swivel plate 55, the upper surface rotation of swivel plate 55 is connected with the separation wheel 56, the top threaded connection of second collar 53 has stop bolt 511, the internally mounted of second collar 53 has sleeve 57, the inside sliding connection of sleeve 57 has slide bar 58, the front end sliding connection of slide bar 58 has second extension rod 59, the front end outer wall threaded connection of slide bar 58 has second fastening bolt 510.
Please refer to fig. 12: the user can slide the lifting frame 12 to the position of the cutter bar 2 under the influence of the state in fig. 9 when in use, because the cutter bar 2 is smaller than the diameter of the main shaft 1, the user can lengthen the first extension rod 411 to be close to the surface of the cutter bar 2, the user starts the main shaft 1 to drive the cutter bar 2 to rotate, the cutter bar 2 can collide with the dial indicator 410 if polarization occurs, the user can judge the polarization of the cutter bar 2 by checking the pointer swing on the dial indicator 410, if the swing is large, the polarization is small, the swing is small, the polarization is small, and the user also needs to lean the separating wheel 56 on the outer wall of the dial indicator 410 when the cutter bar 2 is detected, and then lengthen the second extension rod 59 to be close to the cutter bar 2 and set a safe distance with the cutter bar 2.
Please refer to fig. 13: the polarization of the cutter bar 2, once exceeding the safety distance, will conflict to control the second extension rod 59 so that the sliding rod 58 slides inside the sleeve 57 to conflict with the rotating plate 55, and the rotating plate 55 will clockwise control the separating wheel 56 to bear against the dial indicator 410 away from the cutter bar 2.
The section of the damping block 47 is in a conical structure with a wide upper part and a narrow lower part, the outer wall of the damping block 47 is tightly attached to the inner wall of the base 46, and the top of the damping block 47 is fixedly connected with the bottom of the first mounting ring 48.
It can be appreciated that: as can be seen from fig. 6, the abutting spring 45 is pressed downward to control the damping block 47 to contact with the base 46, so that friction damping is formed between the first mounting ring 48 and the base 46, and thus a certain damping sense is formed when the user rotates the dial indicator 410, so that the polarization force generated by the spindle 1 or the cutter bar 2 in a safe stroke does not affect the horizontal working position of the dial indicator 410;
secondly, the sequence of the test must be that the spindle 1 is tested earlier than the tool bar 2, because the spindle 1 is mounted directly with the machine tool and the tool bar 2 is mounted with the spindle 1, so that the spindle 1 has no meaning to test the tool bar 2 if the polarization is large, and if the tool bar 2 is tested earlier, it cannot be judged whether the polarization originates from the spindle 1 or the tool bar 2.
The bottom of the first bolt 43 is in contact with the inner wall of the first positioning plate 41, the bottom of the positioning bolt 49 is in contact with the outer wall of the dial indicator 410, and the bottom of the first fastening bolt 412 is in contact with the outer wall of the first extension rod 411.

The pulley 13 is in close sliding fit with the inner wall of the truss 9, and the horizontal section of the truss 9 is in an H-shaped structure.
In this embodiment: the device adopts the lifting frame 12 capable of vertically lifting to move the dial indicator 410 to any position of the top and the bottom of the main shaft 1 or the cutter bar 2 for testing, then in the testing process, the dial indicator 410 is directly contacted with the main shaft 1 or the cutter bar 2 for completing the polarization test, then a safe distance is formed between the slide bar 58 and the main shaft 1 or the cutter bar 2 to be tested, once the polarization is large, a tester certainly cannot withdraw the dial indicator 410, and when the safe stroke is exceeded, the slide bar 58 is abutted against the rotating plate 55 so that the separating wheel 56 controls the dial indicator 410 and the main shaft 1 or the cutter bar 2 to be tested to be rapidly separated, thus the damage to the internal parts caused by the impact of the main shaft 1 or the cutter bar 2 with large polarization to the dial indicator 410 can be avoided, and the safety and the accuracy of the test are further improved.
Second embodiment:

There is a sliding connection between the outer walls of the three retaining bars 64 and the inner walls of the three mounting sleeves 62.
This embodiment: the detachable clamping ring 61 is adopted to lift on the cutter bar 2 to be close to the dial indicator 410 to be adjusted, and the design is adopted to be suitable for cutter bars 2 with different thicknesses, so that compatibility is stronger, leveling of the dial indicator 410 before testing is facilitated, and accuracy in subsequent polarization testing is guaranteed.

Step S4: the lifting frame 12 is slid to the position of the cutter bar 2, because the cutter bar 2 is smaller than the diameter of the main shaft 1, a user can lengthen the first extension rod 411 to be close to the surface of the cutter bar 2, the user starts the main shaft 1 to drive the cutter bar 2 to rotate, the cutter bar 2 can abut against the dial indicator 410 if polarization occurs, the user can judge the polarization of the cutter bar 2 by looking at the pointer swing on the dial indicator 410, if the swing is large, the polarization is small, the user also needs to lean on the separating wheel 56 on the outer wall of the dial indicator 410 when the cutter bar 2 detects, then lengthen the second extension rod 59 to be close to the cutter bar 2 and set a safe distance with the cutter bar 2, the polarization of the cutter bar 2 can abut against the second extension rod 59 once exceeding the safe distance to enable the sliding rod 58 to slide against the rotating plate 55 in the sleeve 57, and the rotating plate 55 can control the separating wheel 56 to abut against the dial indicator 410 clockwise to be far away from the cutter bar 2.
Step S5: no matter when the spindle 1 is tested and the cutter bar 2 is tested, a user can spray mediums such as rust remover on the spindle 1 and the cutter bar 2 to be tested through the first spray head 86 and the second spray head 87 in the process of rotating the locking plate 14 to lock the lifting frame 12, so that greasy dirt on the spindle 1 and the cutter bar 2 before detection can be wiped, and the spindle 1 and the cutter bar 2 in the testing process are ensured to be clean.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the specification and drawings of the present invention or direct/indirect application in other related technical fields are included in the scope of the present invention.
