Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coupling centering, in particular to a bracket for three-meter method measurement. Background Art
[0002] Since some equipment bearings are sliding bearings, in order to prevent the influence of axial movement on the measurement when aligning the coupling, the three-meter method is used for equipment alignment measurement. The difference between the three-meter measurement method and the two-meter measurement method is that two dial indicators are symmetrically arranged at equal distances from the center of the shaft. While measuring the radial reading and axial reading in one direction, the axial reading is measured in an opposite direction, that is, the axial readings in two relative directions are measured at the same time, which can eliminate the influence of the movement of the shaft on the axial reading when turning. Due to the use of three dial indicators for measurement, the dial indicator bracket is prone to collision or conflict in the limited space before the coupling, making it difficult or inaccurate to position the dial indicator, resulting in deviations in the measurement data, and the dial indicator needs to be re-installed when multiple equipment is being constructed or when a device is being aligned at different times. The construction process is complicated and wastes manpower. When the dial indicator bracket is rotating the equipment, due to the insufficient rigidity of the bracket, the bracket is prone to drooping, which affects the measurement data. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] refer to Figures 1 to 3A three-meter measurement bracket includes a first part 1 and a second part 3 respectively corresponding to a coupling driving end 7 and a coupling driven end 9. The first part 1 is detachably connected to the coupling driving end 7 through a connecting piece, and the second part 3 is used to fix a radial measuring dial gauge 11 and two axial measuring dial gauges 10.
[0019] In the application process, the radial measuring dial gauge 11 and the two axial measuring dial gauges 10 can be first installed on the second part 3, and then connected to the coupling active end 7 through the first part 1. The axial measuring dial gauge 10 is used to measure the axial deviation of the coupling, and the radial measuring dial gauge 11 is used to measure the radial deviation of the coupling.
[0020] Among them, the first part 1 is an "L"-shaped structure, and two axial fixing holes for installing the axial measuring dial indicator 10 are arranged on the longer side of the first part 1, and a radial fixing hole for installing the radial measuring dial indicator 11 is arranged on the shorter side of the first part 1.
[0021] During the installation of the axial measuring dial indicator 10, the head of the axial measuring dial indicator 10 is directly inserted into the axial fixing hole. During the installation of the radial measuring dial indicator 11, the head of the radial measuring dial indicator 11 is directly inserted into the fixing hole, making the installation and fixation of the three dial indicators very convenient.
[0022] The axial fixing hole and the radial fixing hole are both provided with a top screw 8. By rotating the top screw 8, the heads of the axial measuring dial gauge 10 and the radial measuring dial gauge 11 are pressed tightly, and the three dial gauges can be effectively fixed, the measuring accuracy is improved, and the operation is very convenient.
[0023] The second part 3 is a plate-like structure, and connecting parts are provided at both ends of the second part 3. The connecting parts include a stud 6 and two nuts 5. The two ends of the stud 6 respectively penetrate the through holes on the second part 3 and the active end 7 of the coupling, and two bolts are respectively threadedly sleeved on the two ends of the stud 6.
[0024] When the second part 3 is connected and fixed to the active end 7 of the coupling by using the connecting piece, one of the nuts 5 is first threadedly connected to the outside of the end of the stud 6 located on one side of the second part 3, and then the stud 6 is passed through the through hole on the active end 7 of the coupling, and then the other nut 5 is threadedly connected to the other end of the stud 6. By rotating the two nuts 5, the bracket can be installed as a whole on the active end 7 of the coupling.
[0025] The connector also includes a pad 4, which is located between the second part 3 and the active end 7 of the coupling, and the pad 4 is movably sleeved outside the stud 6. By arranging the pad 4 to block the end face of the second part 3 and the active end 7 of the coupling, it is possible to prevent the second part 3 from causing damage to the end face of the coupling body. Among them, the second part 3 can be made according to the outer dimensions of the coupling, the second part 3 can be made according to the coupling spacing, the size can be adjusted at will, and the manufacturing material can be changed. It can be made of a series of materials such as steel, stainless steel, aluminum, copper, wood, plastic, etc., which further facilitates material acquisition and manufacturing.
