Description

Technical Field

[0001] The utility model relates to the technical field of motor shaft manufacturing, in particular to a motor shaft manufacturing clamping device. Background Art

[0002] Clamping devices play a crucial role in the manufacturing of motor shafts. They ensure shaft stability and precision during machining, preventing machining errors and potential safety hazards caused by workpiece movement or vibration. Effective clamping not only improves production efficiency but also ensures product quality.

[0003] The basic principle of a clamping device is to secure a workpiece in place using a defined clamping force to prevent displacement or vibration during machining. The clamping force should be appropriately determined based on factors such as the workpiece's material, shape, and machining requirements, ensuring both machining accuracy and avoiding damage to the workpiece.

[0004] In summary, the background technology of a motor shaft manufacturing clamping device covers multiple aspects, including its importance, basic principles, technical features, and improvement directions for existing technologies. The continuous development and improvement of these aspects will help improve the precision and efficiency of motor manufacturing and promote the overall progress of the motor manufacturing industry.

[0005] The existing motor shaft manufacturing clamping device, when processing the motor shaft, uses multiple extrusion blocks to converge towards the center to fix and clamp the motor shaft to be clamped. These extrusion blocks are usually three, and are set at an angle of 120° to each other. However, the degree of contact between the surface of round steel materials with different radii and the extrusion blocks is also different. In most cases, the round steel material is fixed at three points. In order to adapt to round steel materials with different radii, the contact area between the extrusion blocks and the round steel is relatively low. Utility Model Content
