Abstract
The utility model relates to a coaxiality measuring instrument, which comprises a bottom board, a level dial indicator bracket fixed on the bottom board, a front stop dog, a rear stop dog, a right guide way and a left guide way, wherein a level dial indicator is arranged on the level dial indicator bracket; a slide block is respectively arranged on the right guide way and the left guide way; a movable rod is arranged on the slide block; a spring is also arranged between the slide block and the rear stop dog. A mandrel bracket capable of sliding along with the slide block is also arranged on the slide block; a mandrel vertical to the mandrel bracket is arranged on the mandrel bracket; the front end of the mandrel is provided with a cross dilation shaft; the rear end of the spindle is connected with a locking block through the spring. The movable rod of the utility model is pulled by hand; a cylinder is sheathed on the mandrel; the locking block is moved; the inner side of the cylinder is abutted on the mandrel through the dilation of the dilation shaft; then the mandrel is rotated; the coaxiality of the cylinder can be accurately measured through reading numbers on the dial indicator.
Description
Technical field
The utility model relates to a kind of device of measuring the cylinder right alignment, particularly a kind of axiality measuring apparatus that is used to check the color picture tube cylinder part.
Background technology
At present, the cylinder of producing on the color picture tube production line, need carry out the measurement of right alignment, and measure right alignment equipment is projector, it is more time-consuming to use this measuring equipment measurement to get up, and will often measure in process of producing product, can not be equipped with a lot of projector, its detection method is to be that benchmark comes measured hole with the cylinder inboard, calculates the right alignment of hole and cylinder inboard.The problem that existing universal testing product mainly exists has: measure time-consumingly, will use back projection's centering cylinder sides earlier, adjust the focal length mating holes again, read its full-size and minimum dimension; The scene can't guarantee enough projector apparatus; Projector costs an arm and a leg.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of simple in structure, does not damage cylinder, the axiality measuring apparatus of the clear readability of measurement result when measuring.
For achieving the above object, the technical solution adopted in the utility model is: comprise base plate and be fixed on dial test indicator support on the base plate, positive stop, backstop, right guide rail and left rail, be characterized in, the dial test indicator support is provided with dial test indicator, right guide rail and left rail are provided with slide block, slide block is provided with motion bar, between slide block and backstop, also be provided with spring, and also being provided with on slide block can be with the arbor support of slide block slip, arbor support is provided with the axle vertical with arbor support, the front end of axle offers a cross spreading axis, and the rear end of axle is connected with latch segment by spring.
Another characteristics of the present utility model are: also be provided with the locking device that is used for lock mandrel on the arbor support; The both sides of the spring of mandrels backend also are respectively arranged with back-up ring and packing ring; The front end of axle also is set with discharger.
The utility model on axle, is moved latch segment with cylindrical sleeve with pulling moving motion bar, and the expansion by spreading axis makes the cylinder inboard be adjacent to axle, live spindle then, by the clock gauge accuracy of reading measure the right alignment of cylinder.
