Abstract

The utility model relates to a roundness measuring tool for a tyre die, in particular to a roundness measurement disc. The technical scheme is that the roundness measurement disc mainly consists of a disc table, a bearing seat, a tapered roller bearing, a lifting sleeve, a shaft, a connecting rod, a dial indicator and a standard die sleeve, wherein the center of the disc table is movably connected with the shaft vertical to the disc table, the other end of the disc table is fixed with the standard die sleeve, the shaft is provided with the lifting sleeve capable of moving up and down, and one side of the lifting sleeve is connected with the dial indicator through the connecting rod. The utility model has the advantages that the operation is simple, and the manufacturing cost is low; the measuring instrument is manually operated and can be operated by a fitter without being operated by a specially-assigned person or compiling programs, thereby effectively improving the product quality and the working efficiency.

Description

The roundness measurement dish

One, technical field:

The utility model relates to a kind of tire-mold survey instrument, particularly a kind of roundness measurement dish.

Two, background technology:

The surface roundness of tire, cross curvature and decorative pattern all have very high accuracy requirement, therefore the die cavity index of the core pattern ring of tire-mold is particularly important, pattern ring is to be spliced by pattern block, error appears in pattern block unavoidably in manufacture process, will influence spliced pattern ring like this, cause product quality low, reduce work efficiency.

Three, summary of the invention:

The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of roundness measurement dish is provided, and simple to operate, low cost of manufacture is effectively improved the quality of products, and increases work efficiency.

Its technical scheme is: mainly be made up of disk table, bearing seat, taper roll bearing, lifting cover, axle, connecting link, dial gauge and standard die sleeve, the intermediate active of disk table connects the axle vertical with disk table, the other end fixed standard die sleeve of disk table, described axle is provided with the lifting cover that can move up and down, and a side of lifting cover connects dial gauge by connecting link.

Above-mentioned disk table is by the fixing axle vertical with disk table of bearing seat and taper roll bearing, and described bearing seat on disk table, is installed taper roll bearing by bolt in the bearing seat.

The top of above-mentioned axle is suspension ring fixedly.

The beneficial effects of the utility model are: simple to operate, and low cost of manufacture, measuring instrument is manually, pincers worker can ownly be operated, and needn't have the special messenger to operate and programs, and can effectively improve the quality of products, and increases work efficiency.

Four, description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Among the last figure: disk table 1, bearing seat 2, taper roll bearing 3, bolt 4, lifting cover 5, axle 6, suspension ring 7, connecting link 8, dial gauge 9, standard die sleeve 10, pattern block 11.

Five, embodiment:

With reference to accompanying drawing 1, the utility model mainly is made up of disk table 1, bearing seat 2, taper roll bearing 3, lifting cover 5, axle 6, suspension ring 7, connecting link 8, dial gauge 9, standard die sleeve 10, bearing seat 2 is fixed on the centre position of disk table 1 by bolt 4, two taper roll bearings 3 of bearing seat 2 internal fixation, stationary shaft 6 between two taper roll bearings 3, lifting cover 5 is movably connected on the axle 6, can move up and down, the top of axle 6 is suspension ring 7 fixedly, one side of lifting cover 5 connects dial gauge 9 by connecting link 8, and an end of disk table 1 is by bolt 4 fixed standard die sleeves 10.

During use, the pattern block of having repaired 11 is put in the standard die sleeve, the pattern block 11 that has separated is combined into a full circle once more, be combined into pattern ring, the circularity of calibration standard die sleeve 10, measure by measuring the dial gauge of installing on the axial organ 9, dial gauge 9 can arbitrarily be placed on certain normal location point, 360 ° of measurements of rotation axis then, can highly measure error at certain, measure five points on the general equal height and get final product, the lifting cover 5 on the axle 6 can move vertically, measure the error of curvature of curve radian, repair once more up to measuring error.
