Description
Technical Field
The utility model relates to a checking fixture, in particular to a special checking fixture for rotor runout.
Background
The working strength of the rotor in the engineering machinery is high, the use frequency is high, and the later detection and maintenance work is directly related to the production efficiency; therefore, the detection of a large number of rotors is involved in the process of equipment maintenance, and the defects of single measuring point, insecure fixation of a dial indicator, small measuring range, low accuracy and the like exist in the existing rotor detection.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a special checking fixture for the runout of a rotor, which has the advantages of simple structure, convenience in operation and accurate measured value.
In order to solve the technical problem, the utility model provides a special checking fixture for the runout degree of a rotor, which comprises an iron base, wherein an arc-shaped groove is formed in the iron base; magnetic gauge stands are oppositely arranged on two sides of the arc-shaped groove; a threaded screw rod is arranged on the magnetic meter base; the threaded screw rod is provided with a self-adjusting nut; the self-adjusting nut is provided with a limiting hole; and the self-adjusting nut is also provided with a threaded jackscrew hole communicated with the limiting hole.
The rotor detection can be completed on the large-scale mechanical construction site, and the iron base is convenient to move and fix; but magnetic gauge stand magnetism is inhaled on the iron base, and the arc wall is used for placeeing the rotor, makes things convenient for the axial rotation when rotor detects.
During detection, the screw rod is placed on the opposite magnetic meter seat, and the dial indicator can measure any point on the rotor through the left-right movement of the self-adjusting nut and the up-down movement of the screw rod on the magnetic meter seat; then the self-adjusting nut is fixed by two nuts.
The utility model has high measurement precision, wide range and simple use. The measuring range comprises the bending degree, the jumping degree and the deviation degree of the rotor. The defects of single measuring point, small measuring range, low precision, large error and the like in the conventional single-magnetic-force gauge stand measurement are overcome.

FIG. 1 is a schematic view of the working state of the present invention;
FIG. 2 is a top view of the self-adjusting nut of the present invention;
FIG. 3 is a left side view of the self-adjusting nut of the present invention and a schematic view of the threaded jackscrew hole configuration.
Detailed Description
The utility model is further described with reference to the accompanying drawings in which:
as shown in fig. 1, 2 and 3, the special gauge for the rotor runout degree comprises an iron base 1, wherein an arc-shaped groove 8 is formed in the iron base 1; the two sides of the arc-shaped groove 8 are oppositely provided with magnetic gauge seats 4; the magnetic gauge stand 4 is provided with a threaded screw rod 7; the thread screw 7 is provided with a self-adjusting nut 3; the self-adjusting nut 3 is provided with a limiting hole 5; and the self-adjusting nut 3 is also provided with a thread jackscrew hole 6 communicated with the limiting hole 5.
During detection, the rotor 2 is arranged in the arc-shaped groove 8, the magnetic gauge stand 4 is arranged on two sides of the arc-shaped groove 8, the limiting hole 5 of the self-adjusting nut 3 is inserted into the dial indicator and is fixed by the jackscrew at the position of the threaded jackscrew hole 6, and then the self-adjusting nut 3 is fixed by the two nuts.
The screw rod 7 is erected on the magnetic meter seat 4 which is oppositely arranged, and the dial indicator can measure any point on the rotor 2 by moving left and right of the self-adjusting nut 3 and moving the screw rod 7 up and down on the magnetic meter seat 4. The technical scheme disclosed by the utility model has the advantages of high measurement precision, wide range and simplicity in use. The measurement range includes the degree of curvature, the degree of run-out, and the degree of deviation of the rotor 2. The defects of single measuring point, small measuring range, low precision, large error and the like in the measurement of a single magnetic force gauge seat are overcome.
The dial indicator can measure any point on the rotor 2 by freely moving the self-adjusting nut 3, so that the measurement precision, the curvature, the jumping degree and the deviation degree of the rotor 2 are improved, and the defects of single detection measurement point, infirm fixation of the dial indicator, small measurement range and low precision of the conventional rotor 2 are overcome.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the utility model, and the utility model is intended to be covered by the appended claims. The scope of the present practical novel claims is defined by the appended claims and equivalents thereof.
