Abstract
An outer diameter gauge for a cylindrical spiral spring is an inverted U-shaped steel sheet, which is symmetrical about the central line; and the distance between vertical sheets on two sides of the inverted U-shaped steel sheet is equivalent to the outer diameter of the tested cylindrical spiral spring. The upper distance between the two vertical sheets of the inverted U-shaped steel sheet is smaller than the outer diameter of the tested cylindrical spiral spring. The outer diameter gauge has the characteristics that the structure is applicable to testing the outer diameter of all identical item points of the cylindrical spiral spring and only needs to be designed according to the corresponding spring tolerance limit values, the operation is simple, and the outer diameter gauge is practical and suitable for batch production and use.
Description
Technical field
The utility model belongs to the spring cubing, particularly a kind of cylindrically coiled spring external 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 external diameter cubing.Be applicable to the helical spring external diameter scope that detects.
Content of the present utility model is:
A kind of cylindrically coiled spring external diameter cubing is characterized in that: the ∏ font steel disc with the center line symmetry; Distance between the riser of ∏ font steel disc both sides is the helical spring external diameter of tested cylinder.
The distance of top is less than the helical spring external diameter of tested cylinder between ∏ font steel disc two risers.
The characteristics that this is practical:
The identical corner of cylindrically coiled spring outward 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 external diameter cubing
Embodiment
A kind of cylindrically coiled spring external diameter cubing as shown in Figure 1, a ∏ font steel disc 1 with the center line symmetry; Distance 2 between the riser of ∏ font steel disc both sides is the helical spring external diameters of tested cylinder.
The distance 3 of top is less than the helical spring external diameter of tested cylinder between ∏ font steel disc two risers.
Spring external diameter cubing: spring is placed the inspection platform, with the spring center line is benchmark, cubing vertically is placed on the spring outside, check 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 the spring external diameter, and then maximum limit of size is qualified.From the both ends of the spring inspection, the optional position all can not be passed through with the external diameter not-go-end, and then the minimum limit of size is qualified.Cylindrically coiled spring external diameter cubing is the middle external diameter of detection springs parameter.
Claims (2)
1. a cylindrically coiled spring external diameter cubing is characterized in that: the ∏ font steel disc with the center line symmetry; Distance between the riser of ∏ font steel disc both sides is the helical spring external diameter of tested cylinder.
2. cylindrically coiled spring external diameter cubing according to claim 1 is characterized in that: the distance of top is less than the helical spring external diameter of tested cylinder between ∏ font steel disc two risers.
