However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0025] As Figures 1-6 shown, in an embodiment of the present utility model: A diameter detection device for valve production includes a valve detection table 1.

A limit baffle 204 is fixedly installed at one end of the limit rod 202. A moving push plate 3 is installed inside the valve detection table 1. A limit frame 4 is installed at the top of the valve detection table 1;

[0027] A servo motor 401 is installed at the top of the limit frame 4, and an output gear 402 is fixedly installed on the output shaft of the servo motor 401, a scale 403 is fixedly installed on the side of the limit frame 4, a transmission screw 5 is installed inside the limit frame 4, and a connecting shaft 501 is fixedly installed on one end of the transmission screw 5, a transmission gear 502 is fixedly installed on the surface of the connecting shaft 501, an internal threaded slider 503 is installed on the surface of the transmission screw 5, and a connecting slider 504 is fixedly installed on the surface of the internal threaded slider 503, a measuring rod 505 is fixedly installed on the side of the connecting slider 504, and a scale indicating baffle 506 is fixedly installed on the top of the measuring rod 505.

[0028] Through the above technical solution, the valve to be tested can be aligned and fixed using the valve fixing platform 2, and then two sets of measuring rods 505 can be attached to the inner wall of the valve connecting pipe. In this way, the valve diameter can be accurately tested.

[0029] A device mounting plate 101 is fixedly installed at the bottom of the valve detection platform 1. The left side of the interior of the valve detection platform 1 is a hollow structure. Two groups of rectangular holes are opened at the top of the valve detection platform 1, and four groups of circular through holes are opened inside the device mounting plate 101.

[0030] Through the above technical solution, the valve detection platform 1 can be fixedly installed by using the device mounting plate 101 to prevent the valve detection platform 1 from moving when in use.

[0031] A group of arc-shaped grooves are provided inside the valve fixing platform 2 , the side surface of the valve clamping block 201 is an arc-shaped structure, and circular through holes matching the size of the limiting rod 202 are provided on both sides of the valve fixing platform 2 .

[0032] Through the above technical solution, the valve clamp 201 can be pushed and resisted by the clamping spring 203, so that when the valve is placed on the top of the valve fixing platform 2, the valve clamp 201 will resist on both sides of the valve under the elastic force of the clamping spring 203, thereby fixing the valve.

[0033] A limit slider 301 is fixedly installed at the bottom end of the movable push plate 3, and a connecting rod 302 is fixedly installed at the top of the limit slider 301. A push rod 303 is fixedly installed on the left side of the movable push plate 3, and a return spring 304 is installed on the surface of the push rod 303. A push block 305 is fixedly installed at one end of the push rod 303.

[0034] A set of rectangular slots matching the size of the limit slider 301 is provided on the inner wall of the bottom end of the valve detection platform 1 , and the connecting rod 302 matches the size of the rectangular hole slot provided on the top end of the valve detection platform 1 .

[0035] Through the above technical solution, when the push block 305 is pushed, the movable push plate 3 will slide to the right, thereby driving the limit frame 4 to move to the right, so that the measuring rod 505 can be inserted into the valve connecting pipe and measure its diameter.

[0036] The surface of the output gear 402 meshes with the surface of the transmission gear 502 , and the interior of the internal thread slider 503 is provided with threads that mesh with the surface of the transmission screw 5 .

[0037] Through the above technical solution, the driving screw 5 can be rotated by the rotation of the servo motor 401, so that the driving screw 5 can move the two groups of measuring rods 505 simultaneously when rotating, and the valve diameter can be detected by measuring the distance between the two groups of measuring rods 505.

[0038] The utility model also provides a pneumatic valve, including a pneumatic valve body 6, connecting flanges 601 are fixedly installed at both ends of the pneumatic valve body 6, a pneumatic controller 602 is installed at the top of the pneumatic valve body 6, a control knob 603 is installed at the top of the pneumatic controller 602, circular through holes are evenly opened on the surface of the connecting flange 601, and the surface of the pneumatic valve body 6 has the same curvature as the groove at the top of the valve fixing platform 2.

[0039] In summary, the working principle of the utility model is as follows: when the valve diameter needs to be accurately detected, the pneumatic valve body 6 that needs to be detected is placed on the top of the valve fixing platform 2. After the pneumatic valve body 6 is placed in the groove at the top of the valve fixing platform 2, the valve clamp 201 will be squeezed when the pneumatic valve body 6 is lowered. At the same time, the valve clamp 201 will be reset under the elastic force of the clamping spring 203. The valve clamp 201 can contact the side of the pneumatic valve body 6 and align and fix the pneumatic valve body 6. When the pneumatic valve body 6 is fixed, the movable push plate 3 can be slid to the right by pressing the push block 305. As the movable push plate 3 slides to the right, the limit frame 4 can move to the right When the limit frame 4 moves to the right, the measuring rod 505 can be moved and inserted into the connecting pipe of the pneumatic valve body 6, and the transmission screw 5 can be rotated by the rotation of the servo motor 401. The internal thread slider 503 can slide on its surface by the rotation of the transmission screw 5. The sliding of the internal thread slider 503 can make the two groups of measuring rods 505 move at the same time. When the two groups of measuring rods 505 are moved, the measuring rods 505 can be pressed against the inner wall of the connecting pipe of the pneumatic valve body 6. At this time, check the position indicated by the scale indicating baffle 506, and the diameter of the pneumatic valve body 6 can be detected by the scale of the scale 403 indicated. The diameter of the pneumatic valve body 6 can be detected more accurately in this way.
