The concentricity of the shaft hole or mounting hole on it directly affects the operating efficiency and stability of the equipment. The traditional measurement methods for measuring the concentricity of the motor frame are either limited by the measurement range and operation difficulty, or require the motor frame to be moved back and forth and adjusted and tested by a medium or large vertical lathe or a three-coordinate measuring machine. Due to the large size and heavy weight of the motor frame of the vertical pump, it is not only difficult to obtain accurate measurement results, but the measurement process is also time-consuming and laborious. Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0036] Please also read Figures 1 to 4 Now, a vertical component concentricity detection tool provided in the embodiment of the present application is described. The vertical component concentricity detection tool comprises a magnetic base 101, a beam 103, a core shaft 104 and a measuring table 105. Among them:

[0037] The magnetic base 101 has an adsorption end face 102 that can be detachably adsorbed on the target component. The magnetic base 101 described in this embodiment can be a device commonly used in the art that can generate magnetic force through switch control and magnetically attract the target component such as the motor frame 200 and other structures. The crossbeam 103 is movably mounted on the magnetic base 101 and can be fine-tuned and moved relative to the magnetic base 101 in a plane parallel to the adsorption end face 102. The mandrel 104 is rotatably mounted on the crossbeam 103 and can rotate relative to the crossbeam 103 around its own central axis, and the central axis of the mandrel 104 is perpendicular to the adsorption end face 102. The measuring table 105 is detachably connected to the mandrel 104 and is used to measure the relative distance between the mandrel 104 and the surface of the target component.

[0038] The method of using the vertical component concentricity detection tool in this embodiment is as follows: first, the magnetic base 101 is adsorbed at the approximate position on the target component and the mandrel 104 is connected to the extension shaft 117 and extended into the hole to be measured on the target component, the mandrel 104 is rotated and the measuring gauge 105 is used to detect the inner wall of a hole close to the end face of the target component, and the position of the crossbeam 103 is adjusted according to the measured value so that the center of rotation of the mandrel 104 is concentric with the hole, so that the position of the crossbeam 103 can be adjusted relative to the magnetic base 101 so that the central axis of the mandrel 104 and the reference installation hole coincide, and the hole can be used as the reference hole. After the position of the crossbeam 103 is fixed, the concentricity or coaxiality of other holes of the target component relative to the reference hole can be measured by changing the axial position of the measuring gauge 105 on the mandrel 104 and rotating the mandrel 104 relative to the crossbeam 103, and the verticality of the measured hole and the end face can also be measured by moving the measuring gauge 105 axially on the extension shaft 117.

[0039] According to the above structure provided in this embodiment, in the vertical component concentricity detection tooling provided in this embodiment, the magnetic base 101 can be stably magnetically attracted to the reference end surface of the target component such as the motor frame 200 and the like, and the mandrel 104 and the extension shaft 117 can be extended into the inner hole of the target component whose concentricity needs to be measured. Since the adsorption end surface 102 of the magnetic base 101 used to adsorb to the target component is parallel to the moving plane of the beam 103 and perpendicular to the mandrel 104, the beam 103 can drive the mandrel 104 to coincide with the central axis of the reference inner hole during the movement relative to the magnetic base 101. In this way, the measuring gauge 105 detachably connected to the spindle 104 can measure the concentricity of the inner holes at different positions on the same axis of the motor frame 200 by being connected to different positions of the spindle 104 and following the rotation of the spindle 104. Not only is the detection result more accurate, but the measurement efficiency is much higher than the prior art. Usually, in order to keep the position of the crossbeam 103 stable after the position is adjusted, a tightening bolt 1032 is provided that passes through the crossbeam 103 and is threadedly connected to the corresponding magnetic seat 101. That is, when the spindle 104 is adjusted to its position by moving the crossbeam 103, the tightening bolt 1032 can be tightened to achieve a firm connection between the crossbeam 103 and the magnetic seat 101. In order to avoid the crossbeam 103 from being in a stable position, the tightening bolt 1032 is provided. During the fine-tuning process of the position, interference occurs between the tensioning bolt 1032 and the crossbeam 103. A through slot 1031 is formed on the crossbeam 103 for the rod of the tensioning bolt 1031 to pass through, and there is a gap between the inner wall of the through slot 1031 and the tensioning bolt 1032, and the gap is adapted to the fine-tunable distance of the crossbeam 103. It can be understood that in the production of this vertical component concentricity detection tooling, its own accuracy should be guaranteed, such as the verticality between the core shaft 104 and the crossbeam 103 and the adsorption surface 102 of the magnetic base 101, and the runout value of the core shaft 104 and the extension shaft 117 when they rotate should be kept within the design requirements and calibrated before use, and the calibration method adopts the calibration technology of existing measuring instruments.

[0040] In another embodiment of the present application, please refer to Figures 1 to 4 At least two magnetic seats 101 are provided along the extension direction of the crossbeam 103, and the core shaft 104 is located between adjacent magnetic seats 101.

Similarly, for the convenience of adjustment, the longitudinal adjustment component is also provided with two groups located at both ends of the beam 103.

[0043] According to the above structure provided in the present embodiment, by rotating the lateral adjustment bolt 108 relative to the lateral adjustment block 107, the lateral adjustment bolt 108 can be brought into contact with the lateral side and the crossbeam 103 can be moved laterally relative to the magnetic base 101; by rotating the longitudinal adjustment bolt 111 relative to the longitudinal adjustment block 110, the longitudinal adjustment bolt 111 can be brought into contact with the top block 109 and the crossbeam 103 can be moved longitudinally relative to the magnetic base 101. In this way, the crossbeam 103 can be flexibly adjusted relative to the magnetic base 101 and the self-locking effect of the crossbeam 103 can be achieved, which is conducive to further improving the convenience of concentricity measurement of the vertical component concentricity detection tooling in the present embodiment.
