Abstract

A tool for measuring the internal diameter of a cylindrical helical spring adopts a steel sheet which is symmetrical based on a central line. The transverse distance of a rectangle on the lower side of the steel sheet is equal to the internal diameter of the to-be-measured cylindrical helical spring in length; and the transverse distance of a rectangle on the upper side of the steel sheet is longer than the internal diameter of the to-be-measured cylindrical helical spring. The utility model is characterized in that the tool is applicable to the internal diameter measurement of same points of the cylindrical helical spring, is only required to be designed according to the tolerance limit value of a corresponding spring, has simple operation and practical use and is suitable for batch production.

Description

Cylindrically coiled spring internal diameter cubing
Technical field
The utility model belongs to the spring cubing, particularly a kind of cylindrically coiled spring internal diameter cubing.
Background technology
The high speed motor car spring is very important to safe train operation, and the parameter of spring directly influences the performance and the stationarity of car load.Present domestic all be to adopt vernier caliper to measure with external diameter in the cylindrically coiled spring, the interior external diameter that this metering system can not the complete reaction spring has just been measured the part; The domestic detection that does not require this corner of cylindrical deviation only requires the detection of this corner at present with volute spring in the Harmony motor train unit; The range detection method that polishes of bearing coil all is that the overwhelming majority is artificial factor here by range estimation.More effective, the more direct quality that guarantees spring of detection by above-mentioned cubing.
The utility model content.
The purpose of this utility model provides a kind of cylindrically coiled spring internal diameter cubing.Be applicable to and detect helical spring inside diameter ranges.
Content of the present utility model is:
A kind of cylindrically coiled spring internal diameter cubing, it is characterized in that: a steel disc with the center line symmetry, the rectangle lateral separation length of steel disc downside is the helical spring interior electrical path length of tested cylinder, and the rectangle lateral separation length of steel disc upside is greater than the helical spring interior electrical path length of tested cylinder.
Characteristics of the present utility model:
In the identical corner of cylindrically coiled spring after testing this kind structure all make suitablely, only need design and get final product according to respective springs tolerance limit value, easy and simple to handle, practicality is suitable for producing by batch use.
Description of drawings
Fig. 1 is a cylindrically coiled spring internal diameter cubing
Embodiment
A kind of cylindrically coiled spring internal diameter cubing as shown in Figure 1, steel disc 1 with the center line symmetry, the rectangle lateral separation length 2 of steel disc downside is the helical spring interior electrical path length of tested cylinder, and the rectangle lateral separation length 3 of steel disc upside is greater than the helical spring interior electrical path length of tested cylinder.
Cylindrically coiled spring internal diameter cubing is the middle internal diameter of detection springs parameter.Spring inside diameter cubing: spring is placed the inspection platform, with the spring center line is benchmark, spring inside diameter cubing: spring is placed the inspection platform, with the spring center line is benchmark, cubing vertically is placed on the spring inboard, checks after making cubing and spring center line parallel, rotate 360 ° of inspections with the cubing go side, the cubing go side should be able to be all by spring inside diameter, and then maximum limit of size is qualified.Check that from the inboard two ends of spring the optional position all can not be passed through with the internal diameter not-go-end, then the minimum limit of size is qualified.The structure of internal diameter cubing is shown in figure (1).
