Embodiment Construction

[0020] The present invention is made up of three parts: circle gauge 1: customized according to the shape of the product, which can be adjusted according to different products; fiber optic sensor 2: the distance between two fiber optic sensors is adjusted according to the tolerance of the number of circles; judgment display lamp 3: the number of circles is within Within the tolerance range, and the bottom ring touches the sensor switch, the green light is on, otherwise the red light is on; Base 4: fixed ring gauge and sensor switch, etc.; contact sensor 5: when the spring is put into the ring gauge, and the bottom When the number of end turns rotates to the specified position, the judgment display light 4 will display a green light.

[0021] specific as Figure 1-2 As shown, the present invention is provided with a position relative ring gauge 1 and a detection bracket 6 on the base 4; the coil gauge 1 is a barrel structure, and the spring 7 is inserted into the bottom of the ...

Abstract

The invention discloses a spring coil number testing device. The spring coil number testing device is characterized in that a base is provided with a position relative coil number gage and a detection support, the coil number gage is of a barrel structure, a spring is inserted into the bottom of the coil number gage, optical fiber sensors are arranged at the positions of two critical values of spring tolerance by the coil number gage, and the detection support is provided with two optical fiber sensors corresponding to the detection support. By means of the structure, the spring coil number testing device has the advantages that automatic detection of the spring coil number is achieved, the reliability of spring quality is guaranteed, the device is suitable for large-scale detection, excessive cost is needless, and production cost is low.

Description

technical field [0001] The invention relates to spring production and inspection, in particular to a spring coil number inspection device. Background technique [0002] For spring manufacturers, the number of coils of the paralyzed spring is one of the important indicators to judge whether the paralyzed spring is qualified. Therefore, when the spring is produced, the number of coils must first be inspected and judged. [0003] At present, the inspection of the number of spring coils depends entirely on manual visual inspection to identify whether the number of coils of the spring is qualified. The subjective line is too strong, and it is easy to make mistakes when conducting mass inspections, and it cannot guarantee that all the coils that leave the factory are qualified. [0004] In view of the above problems, it is a problem to be solved in the prior art to provide a device for checking the number of spring coils, so as to realize the automatic detection of the number of s...
