Description

Technical Field

[0002] A valve production screw assembly machine is typically a device used to automatically attach screws to valves during the valve manufacturing process. This assembly machine typically automatically delivers the screws to the correct position and ensures the correct torque and fixing force are applied to ensure assembly quality and stability. While such an assembly machine can improve production efficiency, reduce manual labor, and ensure assembly accuracy and consistency, existing devices still have some drawbacks, such as:

[0003] For example, a screw assembly machine for valve production with announcement number CN212859257U uses this technology. When the threaded rod is rotated, the threaded rod will make the two clamping plates approach each other. When the two clamping plates approach each other, the workpiece can be clamped. At this time, the two clamping plates will slide along the two sliding rods. When the left and right clamping mechanisms jointly clamp the left and right ends of the workpiece, the screws of the workpiece can be assembled. When the angle needs to be adjusted, the hand wheel is turned. When the hand wheel is turned, the worm can be rotated, and then the worm wheel can be rotated, and the workpiece can be driven to rotate.

[0004] The above device has some problems. The device is cumbersome to use, and it is inconvenient to adjust when fixing valves of different sizes. In addition, the adjustment effect of the valve is not good during the assembly of the screws, and it is inconvenient to assemble the valve in different positions. The overall adjustment effect is not good during use and it is not convenient for people of different heights to use.

[0005] Therefore we have proposed a valve production screw assembly machine device, in order to solve the above-mentioned problems. Utility Model Content
