Abstract
A tool for inspecting rubdown range of a cylindrical helical spring is characterized by a 270-degree gapped ring, wherein surfaces coinciding with the diameters of the gapped ring are arranged at the two end faces of the 270-degree gapped ring. The tool has the following characteristics: the tool is only designed and used according to the corresponding spring tolerance limit valve, is simple and convenient to operate, is practical and is suitable for large scale production inspection.
Description
Technical field
The utility model belongs to the spring cubing, and particularly a kind of cylindrically coiled spring polishes the scope cubing.
Technical background
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 and polishes the scope cubing.Be applicable to the helical spring scope that polishes that detects.
Content of the present utility model is:
A kind of cylindrically coiled spring polishes the scope cubing, it is characterized in that: the missing link of one 270 degree is the faces that overlap with the missing link diameter in the both ends of the surface of missing links of 270 degree.
Characteristics of the present utility model:
This cylindrically coiled spring spring polishes the scope cubing, only needs to design use according to respective springs tolerance limit value, and easy and simple to handle, practicality is suitable for producing by batch in a large number check.
Description of drawings
Fig. 1 is that cylindrically coiled spring polishes the scope cubing
Embodiment
A kind of cylindrically coiled spring as shown in Figure 1 polishes the scope cubing, and the missing link 1 of one 270 degree is that 2, one of locating surfaces are measurement faces 3 in one of the both ends of the surface of missing links of 270 degree, and these two faces are the faces that overlap with the missing link diameter.
Cylindrically coiled spring polishes the scope that polishes that the scope cubing is a detection springs end circle.Cubing is lain in a horizontal plane on the spring end face, " locating surface " alignd with the spring tip, the range estimation spring polishes scope greater than " measurement face ", and it is qualified that then tested spring polishes the scope size.
