Abstract
The utility model discloses a cylindrical deviation check tool of a cylindrical helical spring. The diameter of the inner hole of the cylinder is the external diameter of a tested cylindrical helical spring, and the middle waist of the cylindrical barrel is provided with a radial through hole. The utility model has the characteristics that the structure is suitable for all same corner cylindrical deviation detection of the cylindrical helical spring. The design is carried out according to the corresponding spring tolerance limit. The utility model is convenient to operate and practical.
Description
Technical field
The utility model belongs to the spring cubing, the cylindrical deviation cubing of particularly a kind of cylindrically coiled spring.
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 the cylindrical deviation cubing of a kind of cylindrically coiled spring.Be applicable to and detect helical spring cylindrical deviation range.
Content of the present utility model is:
The cylindrical deviation cubing of a kind of cylindrically coiled spring is characterized in that: a columniform tube, columniform tube diameter of bore is the helical spring outer warp of tested cylinder, at columniform middle waist radial direction through hole is arranged.
Characteristics of the present utility model:
The cylindrically coiled spring identical entry is put cylindrical deviation and is detected this kind structure and all make suitablely, only needs design according to respective springs tolerance limit value and gets final product, and easy and simple to handle, practicality is suitable for producing by batch use.
Description of drawings
Fig. 1 is the cylindrical deviation cubing of cylindrically coiled spring
Embodiment
The cylindrical deviation cubing of a kind of cylindrically coiled spring as shown in Figure 1, a columniform tube 1, columniform tube diameter of bore is the helical spring outer warp of tested cylinder, at columniform middle waist radial direction through hole 2 is arranged.
The cylindrical deviation cubing of cylindrically coiled spring is the b value in the detection springs parameter, as for checking platform, is benchmark with the spring center line with detected spring, and cubing vertically is inserted in spring, cubing bottom surface and contact with platform, the cylindrical deviation b size of then tested spring is qualified.The structure of the cylindrical deviation cubing of cylindrically coiled spring is shown in figure (1).
Claims (1)
1. cylindrical deviation cubing of cylindrically coiled spring is characterized in that: a columniform tube, columniform tube diameter of bore is the helical spring outer warp of tested cylinder, at columniform middle waist radial direction through hole is arranged.
