Description
Technical field
The utility model relates to a kind of surveying instrument, and especially a kind of raceway center distance measurement instrument is particularly at the raceway center distance measurement instrument of two raceway ball bearings.
Background technology
Bearing is the necessary supply of multiple plant equipment such as motor, generator, and two raceway ball bearings also are applied in a plurality of fields as an important component part of field of bearings.Along with the rise of wind-power electricity generation, two raceway ball bearings have obtained a large amount of application as wind power bearing.Along with the application of high precision wind power bearing, the measurement of two raceway ball bearing two raceway centre distance also becomes the prerequisite of producing high-precision bearing.
In the prior art,, be that steel ball is put in the middle of the raceway, measure the difference in height of two raceways, further finish, as shown in Figure 1 by calculating with pit gauge to the measurement of two raceway ball-bearing groove centre distance; This existing manual measurement method is measured inconvenience on the one hand, also can cause measuring accuracy lower owing to the factors such as instability, duplicate measurements and visual error of contact on the other hand, can't guarantee product quality.
Summary of the invention
The purpose of this utility model is in order to solve two technical matterss that raceway ball-bearing groove center distance measurement is constant, error is bigger in the prior art, a kind of simple, convenient, accurate raceway center distance measurement instrument to be provided.
In order to achieve the above object, the technical scheme that the utility model adopted is that a kind of raceway center distance measurement instrument is provided, this measuring instrument comprises a basic chi, one end of described basic chi is fixed with reference column, and described reference column top is provided with the sphere set feeler, is fixed with guide rail on the described basic chi; This measuring instrument also comprises an attachable mechanical stage, described attachable mechanical stage can move along described guide rail, be fixed with joint pin on the described attachable mechanical stage, described attachable mechanical stage joint pin upper end is provided with the sphere metering contact, described sphere metering contact by the attachable mechanical stage joint pin along with attachable mechanical stage moves along guide rail; The described basic chi other end is fixed with the block that can block attachable mechanical stage.
Further, described block is connected with dip stick, and described dip stick and guide rail be arranged in parallel, and described dip stick can slide along block; Described dip stick one end is provided with and withstands end, and described dip stick withstands end can withstand attachable mechanical stage; The described dip stick other end is connected with clock gauge.
Further, described guide rail is provided with clock gauge.
Further, described clock gauge precision reaches micron.
Further, described sphere set feeler and sphere metering contact are the ball crown type structure.
Further, described sphere set feeler and sphere metering contact are replaceable device.
The present invention compared with prior art, its effect is actively and significantly.In measuring process, by the sphere set feeler on the basic chi, a raceway of the two raceway ball bearings in location, the sphere metering contact moves along guide rail; The displacement of sphere metering contact can be read from the clock gauge of crossing on the guide rail; The displacement of sphere metering contact also can pass to dip stick by the end that withstands of attachable mechanical stage and dip stick, reads from the clock gauge that is connected with dip stick.In addition,, can change supporting ball crown type location and metering contact, realize the measurement of the two raceway ball-bearing groove centre distance of different size according to the different size of two raceway ball bearings because sphere set feeler and sphere metering contact are replaceable device.This measuring instrument is simple in structure, and is easy to use, only needs one-shot measurement just can read the raceway centre distance of two raceway ball bearings, solved in the prior art because the low problem of measuring accuracy that factors such as duplicate measurements, contact instability and visual error cause.
Description of drawings
Fig. 1 is the measuring method of the two raceway ball-bearing groove centre distance of prior art;
Fig. 2 is that clock gauge of the present utility model is arranged on the two raceway ball bearing measuring instrument structural representations on the guide rail;
Fig. 3 is that clock gauge of the present utility model is connected the two raceway ball bearing measuring instrument structural representations on the dip stick.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, in the prior art, be the raceway of steel ball being put into two raceway ball bearings 9, measure the difference in height that steel ball is placed on different raceways respectively by pit gauge 10, calculate the raceway central moment of two raceway ball bearings 9.The mode of this artificial twice measurement is measured inconvenience, and error is bigger.
As shown in Figure 2, be arranged on two raceway ball bearing measuring instrument synoptic diagram on the guide rail for clock gauge of the present utility model.End at basic chi 1 is provided with reference column 4, and sphere set feeler 5 is installed on the reference column 4; Be fixed with guide rail 2 on the base chi 1, attachable mechanical stage 3 can move along guide rail 2; Be fixed with joint pin 6 on the attachable mechanical stage 3, the joint pin upper end is equipped with sphere metering contact 7; The other end of base chi is fixed with block 8; Block 8 can block attachable mechanical stage 3, and attachable mechanical stage 3 is dropped out from basic chi 1; Guide rail 2 is provided with the clock gauge that precision can reach micron.
In the measuring process, sphere set feeler 5 is put into a track of two raceway ball bearings 9, moving sphere metering contact 7, and put into another tracks of two raceway ball bearings 9, the displacement of sphere metering contact 7 can directly be read by the clock gauge that is arranged on the guide rail 2, thereby realizes the measurement of two raceway ball bearing 9 raceway centre distance.
As shown in Figure 3, clock gauge of the present utility model is connected the two raceway ball bearing measuring instrument structural representations on the dip stick.Present embodiment and difference embodiment illustrated in fig. 2 are, be connected with dip stick 11 on block 8, dip stick 11 is parallel with guide rail 2, and an end of dip stick 11 is provided with and withstands end 12, withstand end 12 and can withstand attachable mechanical stage 3, the other end of dip stick 11 is connected with clock gauge 13; During measurement, the displacement of sphere metering contact 7 passes to dip stick 11 by attachable mechanical stage 3 by withstanding end 12, and then reads from clock gauge 13.
Because sphere set feeler 5 and sphere metering contact 7 are replaceable structure, can change supporting ball crown type location and metering contact according to the different size of two raceway ball bearings 9, realize the measurement of the two raceway ball-bearing groove centre distance of different size.
