Description

Technical Field

[0001] The invention relates to the technical field of hand wheel machines, in particular to a hand wheel machine assembly mechanism. Background Art

[0002] A handwheel is a manually operated wheel widely used in various machinery and equipment. Also known as a manual pulse generator or hand-cranked pulse generator, handwheels are also used in CNC machine tools, such as vertical machining centers, horizontal machining centers, and gantry machining centers. These CNC machines require a manually operated wheel for precise control. Handwheels are designed with practicality in mind, featuring novel design, ease of movement, strong anti-interference capabilities, and high load capacity.

[0003] Handwheel mechanisms primarily serve as a replacement for manual control valve operation, as a limiter for control valve travel, improving valve reliability, and reducing investment. They are also used in equipment such as CNC machine tools. Handwheel mechanisms are used in the following situations: When a control malfunction occurs, they can replace manual control valve operation to ensure normal equipment operation. As a limiter for control valve travel, when the signal pressure reaches zero, the handwheel mechanism can control the control valve to a half-open or half-closed position, meeting the needs of small process flows. Improving control valve reliability makes the use of handwheel mechanisms cost-effective in terms of both investment cost and floor space, while also increasing system reliability. They can also reduce investment by replacing bypasses, thereby saving costs. Handwheels are used for manual operation on CNC machine tools and other equipment, but their applications are not limited to these situations. They also play an important role in machine tool operation, process commissioning, and improving quality and efficiency. For example, the use of the handwheel retraction function during process commissioning on FANUC machine tools improves processing efficiency and product quality. In addition, the operating principle of the handwheel is based on the principle of leverage. By rotating the central axis and the combination of surrounding spokes, it can achieve the lifting, handling and transportation of heavy objects. It is widely used in industry, transportation, logistics and other fields.

[0004] From the existing technology, the common handwheel machine has a simple structure. It only uses manual and electric power to drive the threaded rod to rotate. It has no adjustment function and cannot adjust the speed. The rare handwheel machine rotates while pulling the handwheel, causing the handwheel and the screw to separate, causing the screw to gradually slow down. The deceleration efficiency is low, and it is necessary to wait for the screw to stop automatically before performing subsequent operations. For this reason, we propose a handwheel machine assembly mechanism. Summary of the Invention

[0005] (1) Technical problems solved In view of the deficiencies in the prior art, the present invention provides a hand wheel machine assembly mechanism, which solves the problems of the prior hand wheel machine such as unadjustable speed and low speed reduction efficiency.
