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
The present invention relates to spring production and check, particularly a kind of number of coils verifying attachment.
Background technology
For spring manufacturing enterprise, the number of turns of paralysis spring is to judge whether one of qualified important indicator of paralysis spring, therefore at first will be to the judgement of testing of its number of turns after spring is produced.
Whether qualified, subjective capable too strong, make mistakes easily when checking in enormous quantities if at present identifying the number of turns of spring by the artificial visually examine fully for the check of the number of coils, can not guarantee that the paralysis of dispatching from the factory is all qualified.
At above-mentioned problem, a kind of number of coils verifying attachment is provided, realize that the automatic detection to the number of coils is the problem that prior art need solve.
Summary of the invention
Technical matters to be solved by this invention is, a kind of number of coils verifying attachment is provided, the purpose that detects automatically with the number of turns that reaches the spring that dispatches from the factory.
For achieving the above object, technical scheme of the present invention is that a kind of number of coils verifying attachment is characterized in that: described verifying attachment is that base is provided with the relative number of turns gauge in position and detects support; Number of turns gauge is the barreled structure, and spring inserts the bottom of number of turns gauge, and number of turns gauge is provided with fiber sensor respectively at two critical value places of spring tolerance; Detect support and be provided with two corresponding with it fiber sensors, thus by fiber sensor to the detecting of spring, when the upper end of spring judges then that in margin tolerance product is qualified.
The shape of described number of turns gauge customizes according to required detection springs.
The bottom of described number of turns gauge is provided with the contact induction device, judges whether spring touches the bottom of number of turns gauge.
Be respectively equipped with red, green two display lamps on the described detection support, judged result is intuitively shown.
The light sensor pilot relay KA1 of described top, the light sensor pilot relay KA2 of below, contact induction device pilot relay KT; The normally opened contact of the normally closed contact of relay K A1 and relay K A2 inserts in the circuit of display lamp green light; The normally opened contact of relay K A1, relay K A2 inserts in the circuit of display lamp red light; The normally closed contact of relay K A2, relay K A1 normally opened contact insert in the circuit of display lamp red light.
Described verifying attachment when the position, termination of the number of coils about judge that then spring is qualified between two fiber sensors the time, give a green light; When the number of coils be the position, termination about judge that then spring is defective outside two fiber sensors the time, send out a warning.
A kind of number of coils verifying attachment owing to adopt above-mentioned structure, the invention has the advantages that: 1, realize the automatic detection to the number of coils; 2, guarantee the reliability of spring-mass; 3, be applicable to large-scale detection; 4, need not too much cost, production cost is lower.

Embodiment
The present invention is made up of three parts: number of turns gauge 1: with the shape of product customization, can adjust according to different product; Be fiber sensor 2: adjust two fiber sensor spacings according to number of turns tolerance; Judge display lamp 3: the number of turns is in margin tolerance, and the foundation ring touches inductive switch, and then green light is bright, otherwise then red light is bright; Base 4: retainer plate quantity rule and inductive switch etc.; Contact induction device 5: when spring is put into number of turns gauge, and the bottom number of turns judges display lamp 4 when rotating to assigned address, just can show green light.
Concrete shown in Fig. 1-2, the present invention is provided with the relative number of turns gauge 1 in position and detects support 6 for base 4; Number of turns gauge 1 is the barreled structure, the bottom that spring 7 inserts number of turns gauge 1, and number of turns gauge 1 is provided with fiber sensor 2 respectively at two critical value places of spring 7 tolerances; Detect support 6 and be provided with two corresponding with it fiber sensors 2, thereby by the detecting of 2 pairs of springs 7 of fiber sensor, when the upper end of spring 7 judges then that in margin tolerance product is qualified.The shape of number of turns gauge 1 customizes according to required detection springs.
The bottom of number of turns gauge 1 is provided with contact induction device 5, judges whether spring 7 touches the bottom of number of turns gauge.Detect on the support 6 and be respectively equipped with red, green two display lamps 3, judged result is intuitively shown.
By reference to the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted technical solution of the present invention to carry out, or directly apply to other occasion without improvement, all within protection scope of the present invention.
