Technical Field

[0001] The invention relates to the technical field of size detection, in particular to a solenoid valve port size detection device. Background Art

[0002] The solenoid valve port is where the medium passes through. The larger the diameter of the solenoid valve port, the more medium can pass through the port per unit time. When manufacturing the solenoid valve, the size of its port needs to be tested. When testing the solenoid valve port, you can use a plug gauge for testing. During the test, the through gauge can be inserted into the port, while the no-go gauge can be inserted without entering the port (the diameter of the through gauge is slightly larger than the minimum diameter allowed by the product port, and the diameter of the no-go gauge is slightly smaller than the maximum diameter allowed by the product port).

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] It can be seen from the above structure that: by setting up the transmission belt 3, the fixing mechanism, the detection drive plug and the three loosening components, etc., the detection of the solenoid valve port can be automatically completed, saving labor, and at the same time the solenoid valves after the detection can be transmitted separately, so that qualified solenoid valves, solenoid valves with too large ports and solenoid valves with too small ports can be separated, so that users can collect the solenoid valves with too small ports and reprocess the solenoid valves with too small ports.

[0020] Further, the fixing mechanism includes a shell 6 fixedly connected to the transmission belt 3, and a clamping plate 7 is slidably connected to the inner wall of the shell 6, a first oblique block 8 is fixedly connected to one side wall of the clamping plate 7, and a second oblique block 9 is arranged on one side of the first oblique block 8, a screw 10 is threadedly connected to the inner wall of the second oblique block 9, and one end of the screw 10 is rotatably connected to the inner wall of the shell 6, the other end of the screw 10 penetrates the shell 6 and extends to the outside of the shell 6, one end of the screw 10 located outside the shell 6 is fixedly connected to the first gear 11, a first rack 12 is fixedly connected to one side wall of the frame 1, a reset member 13 is fixedly connected to one side wall of the clamping plate 7, and one end of the reset member 13 is fixedly connected to the inner wall of the shell 6; By setting up a shell 6, a clamping plate 7 and a screw 10 for use together, when in use, the solenoid valve to be tested is placed in the shell 6, and then the first motor 4 is turned on, so that the first motor 4 drives the rotating drum 2 and the transmission belt 3 to operate, and the operating transmission belt 3 drives the fixing mechanism to move. After the fixing mechanism moves to a certain position, the first gear 11 engages with the first rack 12, so that the first rack 12 drives the first gear 11 to rotate, and the rotating first gear 11 drives the second oblique block 9 to move, and the moving second oblique block 9 drives the first oblique block 8 to move, and the moving first oblique block 8 drives the clamping plate 7 to move, so that the clamping plate 7 clamps the solenoid valve, so that there is no need to manually rotate the screw 10 for clamping, thereby making the fixing of the solenoid valve convenient and quick, and facilitating the use of the device.

[0021] Furthermore, the detection drive plug includes two support plates 14 fixedly connected to the frame body 1, and a stud 15 is rotatably connected to a side wall of one side of the support plate 14, one end of the two studs 15 is fixedly connected together, and the threads of the two studs 15 are opposite, the outer wall thread sleeve of the stud 15 is provided with a fixing plate 16, and a connecting rod 17 is fixedly connected to a side wall of one side of the fixing plate 16, a sliding rod 18 is arranged between the two support plates 14, and the sliding rod 18 penetrates the fixing plate 16, and the two ends of the sliding rod 18 are respectively fixedly connected to the two support plates 14, one end of one of the studs 15 penetrates the support plate 14 and extends to one side of the support plate 14, and the outer wall of the stud 15 located on one side of the support plate 14 is fixedly connected to a second gear 19, The side wall of the support plate 14 is fixedly connected to the second motor 20, and the driving end of the second motor 20 is fixedly connected to the third gear 21, and the third gear 21 is meshed with the second gear 19; by setting the second motor 20, the third gear 21 and the stud 15 for use in conjunction with each other, before use, a go gauge is fixed to one end of the connecting rod 17 on the fixing mechanism on the upper surface of the frame 1, and a stop gauge is fixed to the connecting rod 17 on the fixing mechanism below. When the second motor 20 is started, the second motor 20 can drive the third gear 21, the second gear 19 and the stud 15 to rotate, and the rotating stud 15 can drive the fixed plate 16 to move, and the moving fixed plate 16 can drive the go gauge or the stop gauge to move, thereby completing the detection of the go gauge or the stop gauge.

[0022] The second gear 19 includes a rotating disk 191 fixedly connected to the stud 15, and the outer wall of the rotating disk 191 is rotatably sleeved with a toothed ring 192, the inner wall of the toothed ring 192 is fixedly connected with a first oblique tooth 193, the inner wall of the rotating disk 191 is provided with a cavity, and the inner wall of the cavity is fixedly connected with a spring sheet 194, one end of the spring sheet 194 is fixedly connected with a second oblique tooth 195, and one end of the second oblique tooth 195 passes through the rotating disk 191 and extends to the inner part of the toothed ring 192; by setting the rotating disk 191, the toothed ring 192, the first oblique tooth 193 is fixedly connected with the first oblique tooth 193, and the second oblique tooth 195 is fixedly connected with the second oblique tooth 195. The ring 192 and the like are used in combination. When the go gauge or the no-go gauge cannot be inserted into the port of the solenoid valve, the continuously rotating third gear 21 can drive the gear ring 192 to rotate. When the rotating gear ring 192 rotates, the second bevel teeth 195 can be retracted into the cavity, so that the gear ring 192 can stop driving the turntable 191 to rotate, so that the turntable 191 and the stud 15 can stop rotating, thereby avoiding the stud 15 continuously driving the go gauge or the no-go gauge, which may cause the go gauge or the no-go gauge to damage the port of the solenoid valve.

[0023] Furthermore, the release assembly includes a second rack 22, and a side wall of the second rack 22 is fixedly connected to an electric push rod 23, and the electric push rod 23 is fixedly connected to the frame 1; by setting the electric push rod 23 to be used in conjunction with the second rack 22, the electric push rod 23 can be controlled so that the electric push rod 23 pushes the second rack 22 to the moving path of the first gear 11.

[0024] Furthermore, a socket 24 is fixedly connected to the side wall of the shell 6, and a rod 25 is provided on one side of the socket 24, and the rod 25 is fixedly connected to the fixed plate 16; by arranging the rod 25 for use in conjunction with the socket 24, before the through gauge or the stop gauge is inserted into the port, the rod 25 will first be inserted into the socket 24, and the rod 25 will cooperate with the socket 24 to limit the shell 6, thereby ensuring the accuracy of the position of the shell 6 and the solenoid valve in the shell 6.

[0025] Furthermore, a controller 26 is fixedly connected to the side wall of the frame 1, and the controller 26 is electrically connected to the electric push rod 23. A detection switch 27 is fixedly connected to the side wall of the support plate 14, and the detection switch 27 is electrically connected to the controller 26. By setting the controller 26 and the detection switch 27 for use in conjunction with each other, the detection switch 27 can detect whether a go gauge or a stop gauge is inserted into the port of the solenoid valve, so that the controller 26 controls the operation of the electric push rod 23.

[0026] Furthermore, the reset member 13 includes a sleeve 131 fixedly connected to the shell 6, and the inner wall of the sleeve 131 is slidably connected to a rod body 132, the outer wall of the rod body 132 is sleeved with a spring 133, and one end of the spring 133 is fixedly connected to the rod body 132, and one end of the rod body 132 passes through the sleeve 131 and is fixedly connected to the splint 7; by arranging the sleeve 131, the rod body 132 and the spring 133 for use in combination, the spring 133 can push the rod body 132 and the splint 7 to reset after the first gear 11 and the screw 10 are reversed, so as to facilitate the next use of the device.

[0027] In the present invention, before use, a go gauge is fixed to one end of the connecting rod 17 on the fixing mechanism on the upper surface of the frame 1, and a stop gauge is fixed to the connecting rod 17 on the fixing mechanism below; When in use, the solenoid valve to be tested is placed in the housing 6, and then the first motor 4 is driven to drive the rotating drum 2 and the transmission belt 3 to operate, and the operating transmission belt 3 drives the fixing mechanism to move. After the fixing mechanism moves to a certain position, the first gear 11 is meshed with the first rack 12, so that the first rack 12 drives the first gear 11 to rotate, and the rotating first gear 11 drives the second oblique block 9 to move, and the moving second oblique block 9 drives the first oblique block 8 to move, and the moving first oblique block 8 drives the clamping plate 7 to move, so that the clamping plate 7 clamps the solenoid valve; After the solenoid valve is clamped, the clamped solenoid valve moves to one side of the through gauge, the first motor 4 is stopped, and the second motor 20 on the first detection drive plug is started at the same time. The started second motor 20 drives the third gear 21 to rotate, and the rotating third gear 21 drives the second gear 19 to rotate, and the rotating second gear 19 drives the two studs 15 to rotate, and the rotating studs 15 drive the two fixed plates 16 to approach each other, and the fixed plates 16 approaching each other drive the connecting rod 17 and the through gauge to approach the solenoid valve. If the through gauge cannot be inserted into the port of the solenoid valve, it means that the through gauge detection is unqualified and the port of the solenoid valve is too small; if the through gauge can be inserted into the port of the solenoid valve, after the through gauge is inserted to a certain position of the port, the fixed plate 16 contacts the detection switch 27, and after the fixed plate 16 contacts the detection switch 27, it means that the through gauge can be fully inserted into the port of the solenoid valve, indicating that the through gauge detection is qualified; If the through gauge test fails, after the fixing mechanism of the fixed solenoid valve moves to the side of the first loosening component, the controller 26 controls the electric push rod 23 on the first loosening component to push the second rack 22 to move, so that the second rack 22 on the first loosening component moves to the side of the first gear 11. When the fixing mechanism continues to operate, the second rack 22 meshes with the first gear 11, so that the second rack 22 can drive the first gear 11 to reverse, and the reversed first gear 11 allows the clamping plate 7 to release the clamping of the solenoid valve, and then the solenoid valve can fall on the first conveyor belt 5, so that the solenoid valve is conveyed away by the first conveyor belt 5; If the through gauge test is qualified, the running transmission belt 3 drives the fixing mechanism and the solenoid valve to the side of the stop gauge. After the solenoid valve runs to the side of the stop gauge, the first motor 4 is stopped, and the second motor 20 on the second detection drive plug is started at the same time. The started second motor 20 drives the third gear 21 to rotate, and the rotating third gear 21 drives the second gear 19 to rotate. The rotating second gear 19 drives the two studs 15 to rotate, and the rotating studs 15 drive the two fixing plates 16 to approach each other. The fixing plates 16 approaching each other drive the connecting rod 17 and the stop gauge to approach the solenoid valve. If the stop gauge cannot be inserted into the port of the solenoid valve, it means that the stop gauge test is qualified; if the stop gauge can be inserted into the port of the solenoid valve, the stop gauge and the fixing plate 16 can continue to move, and the fixing plate 16 will contact the detection switch 27. After the fixing plate 16 contacts the detection switch 27, it means that the through and stop gauge can be fully inserted into the port of the solenoid valve, which means that the through and stop gauge test is unqualified; If the stop gauge test fails, after the fixing mechanism for fixing the solenoid valve moves to the side of the second release component, the controller 26 controls the electric push rod 23 on the second release component to push the second rack 22 to move, so that the second rack 22 on the second release component moves to the side of the first gear 11. When the fixing mechanism continues to operate, the second rack 22 meshes with the first gear 11, so that the second rack 22 can drive the first gear 11 to reverse, and the reversed first gear 11 allows the clamping plate 7 to release the clamping of the solenoid valve, and then the solenoid valve can fall on the second conveyor belt 5, so that the solenoid valve is transported away by the second conveyor belt 5. If the stop gauge test is qualified, when the fixing mechanism of the fixed solenoid valve runs to the side of the third loosening component, the controller 26 controls the electric push rod 23 on the third loosening component to push the second rack 22 to move, so that the second rack 22 on the third loosening component moves to the side of the first gear 11. When the fixing mechanism continues to operate, the second rack 22 engages with the first gear 11, so that the second rack 22 can drive the first gear 11 to reverse. The reversed first gear 11 allows the clamp 7 to release the clamping of the solenoid valve. At this time, the solenoid valve can fall on the third conveyor belt 5, and the solenoid valve is transported away by the third conveyor belt 5.
