Abstract
The utility model discloses an internal correcting expanding spindle, which consists of a spindle body, an elastic sleeve, a springs, a sliding sleeve and a pressing nut. One end of the spindle body is installed in the elastic sleeve; the spring and the sliding sleeve are in turn installed on the spindle body of the elastic sleeve; the pressing nut is installed on the spindle body outside the sliding sleeve. The utility model has advantages that the measure range is large, the axiality of the rotation axis of the measured element and the center line of the measured element is guaranteed by the measuring data, the accuracy of measuring and positioning is higher, the measuring positioning error is cancelled, the operation is convenient, and the labor intensity can be reduced. The utility model is widely used in various processes of long body case internal correcting measuring, in particular to measuring the long body case holes of oil submersible electric pump machine.
Description
One, technical field
The utility model relates to measurement mechanism, relates in particular to a kind of Electric Submersible Pump Unit body and function endoporus centering expanding arbor that encrusts.
Two, background technology
The existing body endoporus aligning method that encrusts, be directly to measure the housing endoporus with dial gauge, its shortcoming or deficiency are: (1) can only be on a cross section, measure in the perhaps very little scope, therefore, the data of measurement can not guarantee the right alignment of the axis of rotation and the center line of itself of measured piece; (2) measure inconvenience, labour intensity is big; (3) measurement has positioning error, and measuring accuracy is low.
Three, summary of the invention
The purpose of this utility model is for shortcoming or the deficiency that overcomes or avoid existing in the above-mentioned prior art, and a kind of endoporus centering expanding arbor is provided.
Endoporus centering expanding arbor described in the utility model, comprise mandrel body, resilient sleeve, spring, sliding sleeve and gland nut, described mandrel body one end is installed in resilient sleeve, and spring and sliding sleeve are installed on the mandrel body in resilient sleeve successively, and gland nut is installed on the mandrel body of sliding sleeve outer end.
Wherein, described mandrel body one end is the boss shape Outer Taper, and the middle part is provided with the external thread that matches with gland nut, and the other end is the polished rod structure, and its end is flat side.Described sliding sleeve outer end is the boss shape Outer Taper.Described resilient sleeve two ends are inner cone, with the boss shape Outer Taper formation matching pair of mandrel body and sliding sleeve.Described resilient sleeve is provided with axial pass trough.
The utility model compared with prior art has following advantage:
1, measure in the 180mm scope of the overhanging polished rod surface of mandrel body with dial gauge, convenient, accurate, therefore, the data of measurement can guarantee the right alignment of the axis of rotation and the center line of itself of measured piece; (2) the matching pair structure that has adopted resilient sleeve and mandrel body and sliding sleeve cone to constitute, measurement, setting accuracy height have been eliminated positioning error; (3) measuring operation is convenient, and labour intensity is little.
Four, description of drawings
Fig. 1 is the utility model example structure synoptic diagram.
Fig. 2 is a resilient sleeve structural representation shown in Figure 1.
Five, specific embodiments
Consult a kind of endoporus centering of Fig. 1, Fig. 2 expanding arbor, comprise mandrel body 1, resilient sleeve 2, spring 3, sliding sleeve 4 and gland nut 5.Mandrel body 1 one ends are installed in resilient sleeve 2 internal cavities, and spring 3 and sliding sleeve 4 are installed on the mandrel body in resilient sleeve in turn, and gland nut 5 is installed on the mandrel body of sliding sleeve outer end.
Mandrel body one end is the boss shape Outer Taper, and the middle part is provided with the external thread that matches with gland nut, and the other end is the polished rod structure, and its end is the flat side who makes things convenient for the gland nut dismounting.The sliding sleeve outer end is the boss shape Outer Taper.The resilient sleeve two ends are inner cone, and the boss shape Outer Taper of this inner cone and mandrel body and sliding sleeve constitutes matching pair.Resilient sleeve is provided with axial pass trough 6.
