Technical Field
[0001] The utility model belongs to the technical field of detection mechanisms, and in particular relates to a detection mechanism for inner and outer diameters of a solenoid valve core. Background Art
[0002] The valve core of the solenoid valve is a valve part used to achieve the basic functions of direction control, pressure control or flow control by means of its movement. Its cross-sectional shape is mostly T-shaped or cross-shaped with an inner hole. In order to ensure the normal use and assembly of the subsequent solenoid valve and the accuracy of the start and stop positions, the inner and outer diameters of the valve core need to be tested after production;
[0003] The current common manual inspection is inefficient and not suitable for large-scale assembly line production. Utility Model Content

Such a design ensures smooth movement of the corresponding matching displacement plates.
[0012] It is further defined that the mounting plate of the upper displacement mechanism is provided with an avoidance opening. Such a design is suitable for situations where the length dimension of the measured part is larger than the overall dimension of the outer diameter through gauge.

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0025] like Figure 1 to Figure 3 As shown, a solenoid valve core inner and outer diameter through gauge detection mechanism of the utility model comprises a mounting plate 1, the mounting plate 1 is mounted with a bracket 2 and a support 3, the support 3 is mounted with a positioning ring 4, and the support 3 is provided with a through hole 5 located at the center of the positioning ring 4;
[0026] The bracket 2 is installed with a mounting seat 6, the mounting seat 6 is installed with an upper displacement mechanism 7, the mounting plate 1 is installed with a lower displacement mechanism 8 located in the support 3, the lower displacement mechanism 8 and the upper displacement mechanism 7 have the same structure, and the lower displacement mechanism 8 and the upper displacement mechanism 7 are coaxially symmetrically installed;
[0027] The upper displacement mechanism 7 includes an electric cylinder 71, the output end of the electric cylinder 71 is connected to a displacement plate 72, the displacement plate 72 is installed with a floating joint 73, the floating joint 73 is connected to a connecting piece 74, the connecting piece 74 is slidably installed with three guide rods 75, the outer sides of the three guide rods 75 are all sleeved with springs 76, and the ends of the three guide rods 75 are connected to a mounting plate 77;
[0028] The mounting plate 77 of the upper displacement mechanism 7 is installed with an outer diameter gauge 9, and the mounting plate 77 of the lower displacement mechanism 8 is installed with an inner diameter gauge 10. The cross-sections of the outer diameter gauge 9 and the inner diameter gauge 10 are both T-shaped. The axis of the outer diameter gauge 9 is provided with a detection column hole 11, and the inner diameter gauge 10 is provided with a detection column 12;
[0029] The bracket 2 is provided with a photoelectric sensor 13 whose output end is aligned with the positioning ring 4 .
[0030] In this embodiment, when using a solenoid valve core inner and outer diameter gauge detection mechanism, the part is placed in the positioning ring 4. After the photoelectric sensor 13 senses the part, the upper displacement mechanism 7 and the lower displacement mechanism 8 operate synchronously. The upper displacement mechanism 7 drives the outer diameter gauge 9 to descend to perform a sleeve-type detection on the outer diameter of the part, and the lower displacement mechanism 8 drives the inner diameter gauge 10 to ascend to perform an insertion-type detection on the inner diameter of the part. When the moving distances of the upper and lower electric cylinders 71 both reach the set parameter distance, it indicates that the part is qualified, otherwise it is unqualified.
[0031] During the detection process, the spring 76 plays a protective role. For example, when the inner diameter of the part is unqualified, the detection column 12 of the inner diameter gauge 10 installed on the lower displacement mechanism 8 cannot be fully inserted into the part, and the entire part will be pushed to move toward the upper displacement mechanism 7. When the mounting plate 77 of the upper displacement mechanism 7 and the connected guide rod 75 are displaced, the spring 76 will contract, thereby giving force to the upwardly moving part to prevent the part and the mounting plate 77 from colliding hard and damaging each other. When the lower displacement mechanism 8 returns to its original position, the mounting plate 77 will return to its original position under the effect of the spring 76 to ensure the use effect. When the spring 76 is activated, the equipment stops running to protect the product and equipment.
[0032] Preferably, the mounting plate 1 is slidably mounted with a lower limit rod 14 of a displacement plate 72 fixedly mounted in the lower displacement mechanism 8, and the mounting seat 6 is slidably mounted with an upper limit rod 15 of a displacement plate 72 fixedly mounted in the upper displacement mechanism 7. Such a design ensures smooth movement of the corresponding matching displacement plate 72. In fact, a structure that enables smooth movement of the displacement plate 72 can also be considered according to specific circumstances.
[0033] Preferably, the mounting plate 77 of the upper displacement mechanism 7 is provided with an escape opening 16. Such a design is suitable for situations where the length of the measured part is larger than the overall size of the outer diameter gauge 9. In fact, the specification size of the escape opening 16 can also be considered according to specific circumstances.
[0034] Preferably, both the entrance end of the detection column hole 11 and the contact end of the detection column 12 are provided with chamfers. Such a design is conducive to the coordination with the stroke of the parts. In fact, the size of the chamfer can also be considered according to the specific situation.
[0035] Preferably, the connecting member 74 is installed with a sensor bracket 78. With such a design, by installing a sensor on the sensor bracket 78, it is possible to sense whether the corresponding guide rod is compressed. If compression is detected, it indicates that the position of the part is wrong, and the detection is immediately terminated to protect the product and prevent hard collision damage. In fact, signal transmission measures can also be considered according to specific circumstances.
[0036] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
