Description

Technical Field

[0001] The utility model relates to a solenoid valve, in particular to a quality inspection device for solenoid valves with automatic clamping. Background Art

[0002] A solenoid valve is an industrial device controlled by electricity magnetism and is a basic automation component for regulating fluids (such as gases, water, or other liquids). It drives the opening and closing of a valve through the magnetic force generated by an electromagnetic coil, thereby controlling the flow of the fluid. The response speed of the solenoid valve is crucial in precision machining and automated production lines. Therefore, before leaving the factory, it is also necessary to test its response speed.

[0003] Existing devices for testing the response speed of solenoid valves usually first use clamping tools to fix the solenoid valve to be tested, and then the tester sends an electrical signal to the solenoid valve to test and record the response speed of its stroke push rod after receiving the electrical signal. However, existing testing devices can usually only detect solenoid valves of one specification and cannot adapt to solenoid valves of multiple specifications.

[0004] In view of the above problems, we propose a quality inspection device for solenoid valves with automatic clamping. Content of the Utility Model

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached Figures 1 - 5 drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0029] Embodiment:

[0030] As Figures 1 to 5 shown, an automatic clamping solenoid valve quality inspection device includes a base 11. A wiring port 17 is provided on the base 11. A console 18 is installed at the lower end of the base 11. A plurality of support feet 32 are fixedly connected to the lower end of the console 18, thereby providing stable support for the console 18.

[0031] A clamping mechanism is installed on the base 11. The specific structure of the clamping mechanism is as follows: The clamping mechanism includes a lower abutting cylinder 19. A cylinder 20 for driving the lower abutting cylinder 19 to move up and down is installed on the base 11. The lower abutting cylinder 19 is fixedly connected to the piston rod of the cylinder 20.

[0032] An installation frame 12 is installed on the base 11, a horizontal base 13 is fixedly connected to the installation frame 12, a fixed cylinder 14 is fixedly connected to the lower end of the horizontal base 13, the fixed cylinder 14 is located directly above the lower abutting cylinder 19, the lower end of the fixed cylinder 14 is detachably connected to an abutting cylinder 15, a through groove 26 is axially formed through the abutting cylinder 15, a clamping groove 27 is formed on the lower side of the inner wall of the through groove 26. When testing personnel fix the solenoid valve, first insert the upper end of the solenoid valve into the clamping groove 27, and then the air cylinder 20 drives the lower abutting cylinder 19 to move upward until the lower abutting cylinder 19 presses against the lower end of the solenoid valve, so as to stably clamp the solenoid valve.

[0033] The specific connection manner between the abutting cylinder 15 and the fixed cylinder 14 is as follows: a lower ring 22 is integrally formed on the outer curved surface of the abutting cylinder 15, a through rod 23 is fixedly connected to the lower ring 22, the upper end of the through rod 23 is rotatably connected to a locking plate 24, a locking ring 21 is integrally formed on the outer curved surface of the fixed cylinder 14, and a plurality of through holes 25 are formed in the locking ring 21. When testing personnel install the abutting cylinder 15, first make the locking plate 24 parallel to the through rod 23, and make the through rod 23 and the locking plate 24 pass upward through the through holes 25. When the locking plate 24 is located above the locking ring 21, testing personnel rotate the locking plate 24 to make it perpendicular to the through rod 23, so that the locking plate 24 cannot pass downward through the through holes 25, thereby achieving the purpose of locking the abutting cylinder 15 and preventing the abutting cylinder 15 from falling off the fixed cylinder 14.

[0034] When the staff needs to replace the abutting cylinder 15 according to the specifications of the sample to be tested, only need to rotate the locking plate 24 to be parallel to the through rod 23 and move the abutting cylinder 15 downward, then the abutting cylinder 15 can be disassembled.

[0035] A testing component is installed on the horizontal base 13. The testing component includes a sensor 28 and a sliding probe 29. A protective shell 30 is arranged on the horizontal base 13. The sensor 28 is installed in the protective shell 30. A timer 16 electrically connected to the sensor 28 is installed on the protective shell 30. The sliding probe 29 is located below the sensor 28 and is slidably connected up and down in the protective shell 30. The lower end of the sliding probe 29 extends outside the protective shell 30, passes through the horizontal base 13 and extends into the fixed cylinder 14.

[0036] After the tester fixes the solenoid valve, the stroke push rod of the solenoid valve extends into the fixing cylinder 14 and abuts against the lower end of the sliding probe 29, and the wire on the solenoid valve is plugged into the wiring port 17. Subsequently, the technician energizes the solenoid valve by operating the console 18. The timer 16 starts timing when the solenoid valve is energized. After receiving the electrical signal, the stroke push rod of the solenoid valve pushes the sliding probe 29 to move upward until the upper end of the sliding probe 29 contacts the sensor 28. The timer 16 stops timing and displays the data on the display screen of the console 18.

[0037] It should be noted here that there are a large number of mature technologies in the field to support the sensor 28 in this embodiment. The essence of the present invention lies in optimizing and combining the connection methods of existing hardware machines for specific application scenarios to adapt to the problem of solving the response speed of the solenoid valve test (without changing the internal structure of the sensor 28).

[0038] In addition, an emergency stop switch 31 is provided on the console 18 to facilitate the technician to stop the test in time in case of emergencies to ensure the safety of the test.

[0039] At the same time, it should be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present invention.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
