The dial indicator 2 is installed through the radial indicator rod 1, and the direction of the dial indicator rod is adjusted through the universal movable mechanism 4.

[0023] The universal movable mechanism 4 includes a base 41 and a rotating column 42. The lower part of the rotating column 42 is sleeved in the base 41. The diameter of the column of the rotating column 42 sleeved in the base 41 is larger than the diameter of the column above the rotating column 42. The rotating column 42 and the base 41 are locked by a locking bolt.

[0024] A rocker arm 5 is provided on a horizontal fixed sleeve above the rotating column 42 , and the rocker arm 5 rotates simultaneously with the rotating column 42 to adjust the position of the radial dial rod 1 .

[0025] The radial gauge rod 1 is installed on the end of the rocker arm 5 away from the rotating column 42. The radial gauge rod 1 includes a sleeve structure 11, a fixing rod 12 and an adjusting rod 13. The sleeve structure 11 is sleeved and fixed on the rocker arm 5. The sleeve structure 11 is an annular member composed of two semi-annular members. The top of the semi-annular member is connected to a fixing block. The two fixing blocks are locked by bolts. Loosening the bolts can make the sleeve mechanism 11 adjustable along the axial direction of the rocker arm 5 to change the position of the radial gauge rod 1.

[0026] The fixing rod 12 is fixedly arranged below the sleeve mechanism 11, and the adjusting rod 13 is movably arranged on one side of the fixing rod 12. The fixing rod 12 is provided with an adjusting slot. The adjusting rod 13 is connected to the fixing rod 12 through an adjusting stud 14. The adjusting stud 14 is arranged through the adjusting slot. The bottom of the adjusting rod 13 is arranged lower than the fixed rod 12. The dial indicator 2 is installed below the adjusting rod 13. During measurement, the dial indicator 2 is set on the outside of the split slewing bearing, and the roundness is detected by the dial indicator 2.

[0027] The rotating fixing mechanism 3 includes a roller 31 and a locking structure. The roller 31 is sleeved on the rocker arm 5. The locking mechanism includes a stop sleeve 32, a washer 33 and a locking piece 34. The stop sleeve 32 is sleeved on the rocker arm 5 and fixed by bolts.

Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods and will not be elaborated on.

[0030] Working principle: When the split slewing bearing roundness detection device is used to detect the roundness of the split slewing bearing, first find the center of the split slewing bearing, set the base 41 of the universal movable mechanism 4 at the center of the split slewing bearing, adjust the position of the roller 31 and the measuring point positions of the radial gauge rod 1 and the dial indicator 2 and fix them. The positions of the radial gauge rod 1 and the roller 31 can be adjusted as needed to adapt to the roundness detection of split slewing bearings of different diameters. The length of the radial gauge rod 1 can be adjusted by the adjusting rod 13, which can be used for the split slewing bearing. Testing is performed at different height positions on the outside of the bearing, which is more practical. After the adjustment is completed, the rocker arm 5 is rotated, and the roller 31 rolls along the top of the outer periphery of the split slewing bearing, so that the dial indicator 2 reaches the position that needs to be tested. During the test, the roller 31 can be locked by the locking structure to ensure the stability of the dial indicator 2 during the test, and then the roundness test is performed by the dial indicator 2, which is easy to operate. If the roundness does not meet the requirements after the test, the outer periphery of the split slewing bearing can be slightly vibrated by another auxiliary tool to control the outer ring circle runout of the slewing bearing to be adjusted to within 1mm.
