Embodiment Construction

[0028] A kind of single-toe spring fast check tool, such as Figure 1 to Figure 2 As shown, the entire set of fasteners is based on the detection platform 1, and the upper surface of the platform is finely ground as the reference plane. On the reference plane, groove-shaped middle limb length observation scale 2 and end face distance observation scale 3 are processed; The three components are the positioning shaft 4, the reference slope 5 and the longitudinal reference block 8; the positioning shaft 4 passes through the hole marked on the detection platform and is fixed with a nut, and the reference slope 5 and the longitudinal reference block 8 are fixed on the detection platform by bolts On the calibration position of the datum plane; on the observable side of the datum slope 5, cut a pointed notch 6 and an auxiliary observation scale notch 7 on the buckle surface of the spring strip according to the relevant size requirements of the spring strip for measuring the distance of...

Abstract

The invention discloses a single-toe elastic strip fast detecting tool and a detecting method. The appearance dimension precision of a single-toe elastic strip can be fast and accurately measured for judging whether the dimension of an elastic strip conforms to the technical requirement or not, and the problems of inconvenient measurement and inaccurate measurement caused by the complicated appearance of the elastic strip can be solved. The single-toe elastic strip fast detecting tool and the detecting method have the positive effects that the unified detected state of the elastic strip and the consistency with the work state of the elastic strip are ensured, whether the dimension of the elastic strip conforms to the requirements or not can be conveniently and fast judged through the pass-stop setting in each direction, the process control of mass production and the use acceptance check are met, and the production efficiency and the quality level of the elastic strip can be effectively improved.

Description

technical field [0001] The invention relates to a quick inspection tool and a detection method for a single-toed elastic strip used for railway rails. Background technique [0002] In the domestic urban rail transit fastener system, the elastic strips in the domestic subway single-toe spring fasteners developed on the basis of the British Pandrol PR single-toe spring fasteners have complex shapes and high dimensional accuracy requirements, and the measurement is very difficult. Difficulty, and if there is no effective and rapid inspection method for this type of product that needs to be supplied in large quantities, it will bring considerable difficulties in its production and use. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a single-toe spring fast inspection tool and detection method, which can quickly and accurately measure the shape and dimension accuracy of the single-toe spr...
