Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical equipment, and is a device for centering couplings of rotating equipment widely used in electromechanical, chemical, metallurgical, mining and other industries, and for facilitating the clamping of dial indicators. Background Art
[0002] The chemical and metallurgical industries utilize a large number of high-speed rotating equipment, such as steam turbines, fans, and pumps. Coupling alignment is a crucial aspect of installation, maintenance, and repair. Currently, most methods use a dial indicator to detect and adjust the misalignment between the two couplings to achieve shaft alignment. This involves attaching the dial indicator's magnetic base to the surface of the coupling, clamping the indicator to the support rod, rotating the coupling, and calculating the misalignment between the two coupling halves using the dial indicator reading. The motor's position is then adjusted to ensure the motor and fan shafts are aligned approximately in a straight line.
[0003] This method of using a magnetic stand to clamp a dial indicator has two drawbacks: First, because the two support rods of the magnetic stand are each 200mm long, some equipment with relatively low shafts has very limited space for coupling alignment. Due to interference from the magnetic stand's support rods, the coupling cannot rotate, making the alignment operation impossible. Second, due to the limited suction force of the magnetic base, a slight collision during the alignment operation can cause the magnetic stand and dial indicator to fall together, rendering the alignment work useless; or the dial indicator reading may deviate, resulting in distorted alignment results.
[0004] Therefore, how to improve the stability of the coupling alignment dial indicator clamping, adapt to a narrower construction working environment, improve construction efficiency, and ensure the accuracy of the alignment results is a technical problem that needs to be solved urgently.

[0006] The technical solution of this utility model:
[0007] The rotating equipment coupling alignment dial indicator clamping device includes a main dial indicator frame and an auxiliary dial indicator frame.

The main dial indicator frame body is provided with a curved left hook plate. The auxiliary dial indicator frame includes the auxiliary dial indicator frame body, two auxiliary meter frame positioning screw holes and corresponding auxiliary meter frame positioning screws, and the auxiliary dial indicator frame body is provided with a curved right hook plate.

[0014] The following is an explanation with reference to implementation examples.
[0015] The coupling centering dial indicator clamping device is made of 10mm copper plate in this embodiment, and includes a main dial indicator frame and an auxiliary dial indicator frame.

[0017] Figure 2 、 Figure 3 As shown, the auxiliary dial indicator frame includes an auxiliary dial indicator frame body 7, two auxiliary meter frame positioning screw holes 8 and corresponding auxiliary dial indicator frame positioning screws 16, and below the auxiliary dial indicator frame body 7 is a curved right hook plate 12.
[0018] Figure 3 As shown, the coupling centering dial indicator clamping device is installed and used: the left hook plate 11 of the main dial indicator frame body 1 is hooked onto the edge of the motor-side coupling, and the main dial indicator frame body 1 is fixed to the edge of the motor-side coupling with two main dial indicator frame positioning screws 13. The right hook plate 12 of the auxiliary dial indicator frame body 7 is hooked onto the edge of the fan-side coupling, and the auxiliary dial indicator frame body 7 is fixed to the edge of the fan-side coupling with two auxiliary dial indicator frame positioning screws 16. The measuring rod of the axial dial indicator 3 passes through the axial dial indicator measuring rod insertion hole 9, and the tip of the rod contacts the measuring end face of the auxiliary dial indicator frame 7. The axial dial indicator measuring rod locking screw 14 passing through the axial dial indicator measuring rod locking screw hole 4 is tightened to fix the axial dial indicator 3 to the main dial indicator frame body 1. The measuring rod of the radial dial indicator 5 passes through the radial dial indicator measuring rod insertion hole 10 of the main dial indicator frame body 1, and the tip of the rod contacts the upper measuring surface of the auxiliary dial indicator frame body 7. Tighten the radial dial indicator measuring rod locking screw 15 through the radial dial indicator measuring rod locking screw hole 6 to fix the radial dial indicator 5 on the main dial indicator frame body 1.
[0019] Working Process and Principle: After installing the coupling alignment dial indicator fixture, slowly rotate the motor-side and fan-side couplings simultaneously. Axial dial indicator 3 and radial dial indicator 5 rotate with the couplings. The positional deviation of the motor shaft relative to the fan shaft will be reflected in the readings of the two dial indicators. The deviation is calculated, and the motor position can be adjusted appropriately to achieve coupling alignment.
