Description

Technical Field

[0001] This utility model relates to the field of valve casting production technology, and in particular to a testing device for valve casting production. Background Technology

[0002] A valve is a control device used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. According to function, valves can be divided into shut-off valves, check valves, and regulating valves. The valve casting process generally involves: first, making a model of the valve to be cast in a molding sand mold; then pouring molten iron into the mold; after the molten iron cools and the valve prototype takes shape, removing it from the molding sand mold; finally, the removed valve prototype undergoes grinding, drilling, and painting to initially form the main body of the valve. During the processing of the main body, an inspection device is needed to inspect the outer wall of the valve casting to observe for leaks or other defects. However, traditional inspection devices are inconvenient for inspecting other surfaces of the valve casting, requiring manual flipping or the use of multiple cameras. Manual flipping is inefficient, while multiple cameras are costly.

[0003] Therefore, those skilled in the art have provided a testing device for valve casting production to solve the problems mentioned in the background art. Utility Model Content

A servo motor 207 is fixedly mounted on one side of the inner cavity of the adjusting box 206. A drive gear 205 is fixedly mounted on the output shaft of the servo motor 207. A bidirectional threaded rod 208 has adjusting screw blocks 209 threadedly connected to both sides of its surface. A connecting rod 211 is fixedly installed on one side of the adjusting screw block 209, and a clamping plate 212 is fixedly installed at one end of the connecting rod 211. A drive gear 203 meshes with a driven gear 205. Both the drive gear 203 and the driven gear 205 are high-strength wear-resistant metal gears. A positioning bearing is fixedly installed on the other side of the inner cavity of the adjusting box 206, and the positioning bearing is rotatably connected to the bidirectional threaded rod 208. A guide block 210 is fixedly installed on the other side of the adjusting screw block 209. A guide groove is opened in the inner cavity of the adjusting box 206. A circular groove is opened on the top of the rotating box 201, and the circular groove is rotatably connected to the transmission rod 204.

[0032] In this embodiment: by setting up a casting positioning mechanism 2, the servo motor 207 can drive the two clamping plates 212 to clamp the bottom of the valve casting. By turning on the stepper motor 202, the valve casting can be rotated. The drive gear 203 meshes with the driven gear 205, which facilitates transmission and has high strength and good wear resistance.
