Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valve sleeve detection, in particular to an inner hole specification detection device of an electromagnetic valve sleeve. Background Art

[0002] The solenoid valve sleeve is an important part of the solenoid valve and is located in the valve body of the solenoid valve. Its main function is to fix and protect the core components of the solenoid valve, and also to seal and guide. During the processing of the solenoid valve sleeve, the inner hole specification detection of the solenoid valve sleeve is very important. The solenoid valve sleeve whose inner hole specification does not meet the design requirements will affect the sealing performance of the solenoid valve during use, resulting in medium leakage or unstable operation, and even affecting the safe operation of the equipment.

[0003] The existing detection methods are mostly manual handheld measuring tools, such as micrometers and micrometers, which directly measure the diameter of the inner hole of the solenoid valve sleeve. The detection efficiency is low, and the manual grip of the solenoid valve sleeve may be tilted during measurement, resulting in certain errors in the detection results. Therefore, we propose a solenoid valve sleeve inner hole specification detection device to solve the above problems. Utility Model Content

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] Reference Figure 1 and Figure 2 As shown, a device for detecting the inner hole specification of a solenoid valve sleeve comprises a workbench 1, the upper end of the workbench 1 is fixedly connected to a center column 2, a first slide groove 3 is penetrated through the upper end of the workbench 1, and a fixing plate 4 is fixedly connected to the left and right sides of the lower end of the workbench 1 near the first slide groove 3, a first two-way threaded rod 5 is rotatably connected between the two fixing plates 4, both ends of the first two-way threaded rod 5 are threadedly connected to a limiting plate 6, the limiting plate 6 is slidably connected to the inside of the first slide groove 3, and an anti-slip rubber pad 7 is fixedly connected to the inner side of the limiting plate 6, and the anti-slip rubber pad 7 can increase the friction between the outer surface of the solenoid valve sleeve and make the clamping more stable, the two limiting plates 6 are symmetrically arranged on the left and right sides of the center column 2, the inner side of the limiting plate 6 is arc-shaped, which can fit well with the outer surface of the solenoid valve sleeve, and a first motor 8 for driving the first two-way threaded rod 5 to rotate is fixedly installed on the left side of the left fixing plate 4.

[0022] Furthermore, the first motor 8 can drive the first bidirectional threaded rod 5 to rotate, so that the two limit plates 6 are clamped and fixed close to the outer surface of the solenoid valve sleeve. Since the two limit plates 6 are symmetrically arranged on the left and right sides of the center column 2, when the two limit plates 6 are tightly fitted to the outer surface of the solenoid valve sleeve, the center position of the solenoid valve sleeve will correspond to the center position of the center column 2.

[0023] Two second slide grooves 9 are provided at the upper end of the workbench 1, and the rear end of the rear second slide groove 9 is rotatably connected with a second bidirectional threaded rod 10, and the other end of the second bidirectional threaded rod 10 passes through the front end of the rear second slide groove 9 and is rotatably connected with the front end of the front second slide groove 9, and both ends of the second bidirectional threaded rod 10 are threadedly connected with a measuring plate 11, and an installation groove 14 is provided on the outer side of the measuring plate 11, and a touch switch 15 is provided inside the installation groove 14. The two measuring plates 11 are symmetrically arranged on the front and rear sides of the center column 2, and a second motor 16 for driving the second bidirectional threaded rod 10 to rotate is fixedly installed at the front end of the workbench 1, and the second motor 16 is electrically connected to the touch switch 15.

An infrared receiver 13 is disposed at the upper end of the rear measuring board 11, and a receiving end of the infrared receiver 13 is flush with the front end of the rear measuring board 11. Both the infrared transmitter 12 and the infrared receiver 13 are electrically connected to an external controller.

[0025] Furthermore, when measuring the inner diameter of the solenoid valve sleeve, the second motor 16 will drive the second bidirectional threaded rod 10 to rotate, so that the two measuring plates 11 are close to the inner wall of the solenoid valve sleeve. When the touch switch 15 contacts the inner wall of the solenoid valve sleeve, the two measuring plates 11 will stop moving. At this time, the infrared transmitter 12 emits infrared rays and receives them through the infrared receiver 13. The distance between the two measuring plates 11 can be calculated by recording the infrared receiving and transmitting signals through an external controller. The inner diameter of the solenoid valve sleeve is obtained by adding the measurement result and the thickness of the two measuring plates 11.

[0026] Working principle: When the device is in use, the solenoid valve sleeve is sleeved on the outside of the central column 2 and the measuring plate 11, and the first motor 8 is connected to the power supply. The first motor 8 drives the first bidirectional threaded rod 5 to rotate, so that the two limit plates 6 are close to the outer surface of the solenoid valve sleeve to clamp and fix the solenoid valve sleeve. Then the second motor 16 is connected to the power supply, and the second motor 16 drives the second bidirectional threaded rod 10 to rotate, so that the two measuring plates 11 are close to the inner wall of the solenoid valve sleeve. When the touch switch 15 contacts the inner wall of the solenoid valve sleeve, the two measuring plates 11 will stop moving. At this time, the infrared transmitter 12 emits infrared rays and receives them through the infrared receiver 13. The time difference between the sending and receiving of infrared rays is recorded by the external controller and calculated by a pre-set formula to obtain the inner hole diameter of the solenoid valve sleeve.
