Abstract
The utility model relates to a motor end flop detecting system which is used in CD device. The detecting device system is characterized in that the upper of a motor which is used to load card measured is provided with a plurality of cylinders which enclose a circle, and the lower of a cylinder piston rod is provided with a micro laser ranging sensor, and the diameter of a round which is enclosed by the ends of all the micro laser ranging sensors is at least smaller than that of a measuring round disk which is on the motor output shaft. The cylinder is arranged on a frame of the detecting device, the lower of the piston rod is provided with a fixing frame, the upper of the fixing frame is provided with the micro laser ranging sensor, and the side surface is arranged on a vertical guide. The effects of the utility model are that the measuring device system is convenient to operate, has exact measurement and simple structure, so the utility model is suitable for using in the production line and guarantees the credibility and stability of the products quality.
Description
Technical field
The utility model belongs to the form and position tolerance proving installation, particularly a kind of CD-ROM drive motor face runout detection system.
Background technology
Computer CD ROM requires very strict with the jerk value of motor end face end face in rotary course, generally be controlled between 0.02～0.03mm, if not the jerk value process of motor end face directly has influence on the accuracy that reads of data of optical disk and the life-span of laser reader.Original control method projects to display screen by optical image exactly, and the people judges that by visual inspection the accuracy that detects reduces like this, and human factor is bigger, and can not react concrete deviate.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of CD-ROM drive motor face runout detection system is provided.Be a kind of easy to operate accurate equipment simple in structure.Accuracy of detection is not less than at 0.02～0.03mm.
The technical solution of the utility model is:
A kind of CD-ROM drive motor face runout detection system, it is characterized in that: this pick-up unit system is as follows: above being installed by measured motor, several cylinders that forms a circle is housed, the miniature laser distance measuring sensor is equipped with in the piston rod below of cylinder, and the diameter of a circle that all miniature laser distance measuring sensor lower ends surround is when young in the diameter that is contained in the test plate on the tested motor output shaft.
Cylinder is contained on the support of pick-up unit, and the piston rod below is connected with fixed mount, and the miniature laser distance measuring sensor is installed on the fixed mount, and the side of fixed mount is contained on the vertical guide rail.
The utility model effect is:
This test device system is easy to operate, measures accurately, and is simple in structure, is applicable to use on the production line to have guaranteed the credible and stable of product quality.

Embodiment
The motor face runout detection system of a kind of CD-ROM drive as shown in Figure 1, this pick-up unit system is as follows: above being installed by measured motor 1, several cylinders 2 that forms a circle is housed, miniature laser distance measuring sensor 4 is equipped with in piston rod 3 belows of cylinder, and the diameter of a circle that all miniature laser distance measuring sensor lower ends surround is when young in the diameter that is contained in the test plate 5 on the tested motor output shaft.
Cylinder is contained on the support 6 of pick-up unit, and the piston rod below is connected with fixed mount 7, and the miniature laser distance measuring sensor is installed on the fixed mount, and the side of fixed mount is contained on the vertical guide rail 8.
The CD-ROM drive that my company develops is with motor face runout detection system (seeing Fig. 1,2), adopt several minimum two laser range sensors to measure, when the motor end face is rotated, respectively 2 data acquisition is drawn concrete parameter value after Computerized analysis system is analyzed relatively, and export to and adjust machine and adjust.Adopt native system rear motor face runout can be controlled in the 0.02mm fully, thereby guaranteed the credible and stable of product quality.
