Description

Technical Field

[0001] The invention belongs to the field of coupling alignment tools, and in particular relates to a coupling alignment fixture. Background Art

[0002] D-260-1.24 / 0.93 coke oven gas centrifugal blower is a common gas pressurizing equipment in the metallurgical industry. Its motor (2985r / min) is connected to the gear box (4656r / min) through an elastic diaphragm coupling. After increasing the speed, it is connected to the centrifugal blower through an elastic diaphragm coupling and the gas is pressurized and delivered to the user through high-speed rotation.

[0003] Due to the high speed of the unit, the requirements for the coaxiality of the coupling are also very high, and the coupling alignment accuracy must be within 0.03mm. At the same time, since the gearbox and the blower both use sliding bearings with an axial movement of about 0.30mm, the three-meter method must be used to align the coupling to ensure the alignment accuracy. However, due to the compact design of the unit coupling structure, it is difficult to arrange and fix the dial indicator with an ordinary dial indicator stand and a laser alignment instrument due to the large geometric dimensions. In addition, due to unreliable clamping, the dial indicator is very likely to move during the movement of the coupling, resulting in large errors in the alignment accuracy, and repeated alignment is required for error correction. After the maintenance is completed, the unit vibration often exceeds the standard due to the excessive coaxiality of the coupling. The maintenance efficiency is low and the maintenance quality is difficult to guarantee. Summary of the invention

[0056] The working principle of the coupling alignment fixture is as follows:

[0057] The first clamp body 1, the pad 6 and the second clamp body 5 are fixed on the gear box side coupling 8, and the dial indicator is fixed on the first clamp body 1 and the second clamp body 5, which can ensure that the coaxiality alignment of the D-260-1.24 / 0.93 centrifugal blower coupling can be clamped quickly and reliably, and the dial indicator is not easy to be displaced during the rotation of the coupling, which reduces the alignment accuracy error and greatly improves the efficiency and quality of maintenance work.

[0058] Among them, the positioning groove 61 of the pad 6 is used to install the pad 6 on one end of the gear box side coupling 8 located on the fan side coupling, and then the fixing plate 11, the gear box side coupling 8 and the pad 6 are connected by fasteners, and then the frame rod 12 and the fixing plate 11 are connected by fasteners, and the fixing rod of the first dial indicator 2 is accommodated in the mounting hole 122 of the frame rod 12, and then the fastener is used to install it in the fastening hole 1222, and the fixing rod of the first dial indicator 2 is pressed by the fastener, and then the meter frame 13 is hung on the position of the frame rod 12 located on the fan side coupling 7 by using the accommodating hole 132 of the meter frame 13, and then the position of the meter frame 13 is limited by pressing the fastener 131 and the frame rod 12, and the fixing rod of the second dial indicator 3 is accommodated in the fixing hole 133 of the meter frame 13, and then the fastener is installed in the pressing hole 1332, and the fixing rod of the second dial indicator 3 is pressed by the fastener.
