The utility model discloses a support body, including support body 1, radial dial indicator hole 7 is provided with two in this embodiment, and radial dial indicator hole 7 is vertical to be set up and to be set up on the horizontal segment, transversely be connected with the dial indicator positioning bolt 10 that fastens to radial dial indicator hole 7 on the support body 1, insert radial dial indicator hole 7 with the detection axle of dial indicator 14 after, fasten the side of detecting the axle through dial indicator positioning bolt 10 and realize the fixed of dial indicator 14.
The axial gauge stand 8 is transversely connected to the horizontal section of the frame body 1 in a sliding mode, a hole with the same section as the horizontal section is formed in the axial gauge stand 8, and the axial gauge stand 8 is sleeved on the horizontal section to achieve sliding connection. The axial gauge stand 8 is provided with an axial gauge stand positioning bolt 11 which is pressed against the frame body 1, so that the axial gauge stand 8 can be positioned.
The axial gauge stand 8 is provided with a transverse axial gauge hole 9. Two axial dial indicator holes 9 are arranged up and down, and dial indicator positioning bolts 10 fastened in the axial dial indicator holes 9 are transversely connected to the axial dial indicator base 8.
The measuring method of the utility model comprises the following steps: the two dial indicators are used for measuring the deviation values of the outer circle and the end face of the coupler in the same direction, so the method is also called a point measurement method, namely the radial reading in a certain direction is measured, and the axial reading in the same direction is measured at the same time. The specific method comprises the following steps: firstly, the coupling on the machine which is hoisted in place and is ready to be adjusted is preliminarily measured and adjusted by an angle square. Then, a special fixture and a dial indicator are arranged on the main machine side half coupling serving as a reference, and the contact of the dial indicator points to the excircle and the end face of the main machine side half coupling. During measurement (as shown in FIG. 4), the radial reading a1 and the axial reading s1 are measured at 0 degrees. For the convenience of analysis and calculation, the values of a1 and s1 are usually adjusted to zero, then the coupling halves are rotated simultaneously, the values in the table are read every 90 degrees, and the read values are filled in the record chart. The radial readings a1, a2, a3 and a4 are recorded outside the circle, and the axial readings s1, s2, s3 and s4 are recorded inside the circle, and when the dial indicator is rotated back to the zero position, the readings must be consistent with the original zero position, otherwise, the reason needs to be found and eliminated. The common reason is shaft play or anchor bolt looseness, and the measured reading must meet the following conditions for the reading to be correct, namely a1+ a3= a2+ a 4; s1+ s3= s2+ s4 determines the relative position of the two axes in space by analytical calculation of the measured values, and then adjusts the relative positions according to the calculation result. The method is widely applied and can meet the installation precision requirement of common machines. The main disadvantage is that for the coupling with axial play, the axial degree of the end face of the coupling can generate errors when turning. Therefore, the measuring method is suitable for a rotating shaft supported by a rolling bearing, and the running equipment with small axial play is suitable.
