Description

Technical Field

[0001] The utility model belongs to the technical field of electric valve processing, and in particular relates to a size detection device for electric valve processing. Background Art

[0002] Electric valves use electric actuators to control valves, thereby opening and closing the valves. They can be divided into two parts, the upper part is the electric actuator, and the lower part is the valve. Electric valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

[0003] In the process of realizing the utility model, the inventor found that there are at least the following problems in the technology: in the process of processing electric valves, it is necessary to detect the size of the electric valves, and mass production can only be carried out after determining that their size is qualified. However, the current electric valve size detection device (for example, the patent with application number CN202122295990.4 - a valve size detection structure for valve processing) usually cannot change the position of the scale with the position of the electric valve (produce relative displacement), resulting in the current scale can only detect the center position of the electric valve, and the electric valve is irregular in shape, and it is necessary to detect the size of each position, so the current size detection device is not comprehensive enough.

[0004] Therefore, we propose a dimension detection device for electric valve processing to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a dimension detection device for electric valve processing. With the help of the translation of two receiving frames, the dimension detection at different positions on the electric valve can be realized, making the dimension detection more comprehensive and effectively solving the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The output shaft of the first motor is coaxially connected with the first screw rod, and both ends of the sliding rod are welded to the receiving frame. A lifting frame is also arranged between the two receiving frames, and one end of the lifting frame is threadedly sleeved on the first screw rod, and the other end thereof is slidably sleeved on the sliding rod.

[0009] A second motor is fixedly installed on the lifting frame, wherein a bottom groove is formed on the bottom wall of the lifting frame, and the output shaft of the second motor is coaxially connected to the second screw, the threads at both ends of the second screw have opposite rotation directions, and detection plates are respectively threadedly sleeved on both ends of the second screw, and the two detection plates are both fitted with the top wall of the bottom groove, and the detection mechanism includes a second scale fixedly welded to one side of the bottom wall of the lifting frame and a first scale respectively welded to the opposite sides of the two receiving frames.

[0010] As a preferred embodiment, the first screw rod and the slide rod are both vertically arranged, and the first screw rod and the slide rod are symmetrical on both sides of the lifting frame; so that the first screw rod and the slide rod work together to ensure the balance of the lifting frame structure.

[0011] As a preferred embodiment, both ends of the first screw are rotatably connected to the receiving frame, so that the first motor can drive the first screw to operate stably when it is running.

[0012] As a preferred embodiment, a groove is formed through one side of the lifting frame, and the second motor is horizontally fixed to the inner wall of the groove, so that the second motor structure remains stable.

[0013] As a preferred implementation scheme, the second screw is horizontally arranged in the bottom groove, and both ends of the second screw are rotatably connected to the lifting frame; so that the second screw can operate stably under the drive of the second motor, and both the first motor and the second motor need to be powered by external power facilities.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] The dimension detection device for electric valve processing can realize the dimension detection of the electric valve in the horizontal direction and the vertical direction by cooperating with the first motor and the second motor, and can also make the receiving frame translate on the two limit rods, so that the two scales and the electric valve are relatively displaced, thereby realizing the dimension detection at different positions on the electric valve, making the dimension detection more comprehensive;

[0016] The dimension detection equipment for electric valve processing drives the first motor to operate and drives the first screw to operate, so that the lifting frame is lifted and lowered along with the sliding rod until the bottom wall of the lifting frame contacts the to-be-detected position on the electric valve. At this time, the height value of the electric valve can be read using the first scale, and then the second motor is driven to operate and drives the second screw to operate, so that the two detection plates are translated toward each other. When the two detection plates are in contact with the two sides of the to-be-detected position of the electric valve, the length value of the electric valve can be read using the second scale.
