Description

Technical Field

[0001] This utility model belongs to the field of lathe protection technology, specifically relating to a detachable external protection for a common horizontal lathe. Background Technology

[0002] Ordinary horizontal lathes (such as the CDE-A series) adopt an open structure, with the spindle, motion mechanism, cutting tool, and workpiece system directly visible and touchable. While this provides convenient operability, the exposed working area means that during turning, cutting forces cause chips to fly at speeds of tens of meters per second, potentially injuring the operator's eyes, face, and hands. Long-term inhalation of the metal dust and cutting fluid mist generated during cutting can cause respiratory diseases, and dust accumulation can easily lead to fire hazards. The spindle, chuck, and other components of ordinary lathes are often in an exposed state, and operators may accidentally touch them, leading to entanglement accidents.

[0003] In existing technologies, fully enclosed protective shields are often used for protection. The disadvantages of fully enclosed protective shields include:

[0004] (1) A fully enclosed protective cover may obstruct the operator's view and increase the difficulty of adjusting the workpiece or tool.

[0005] (2) Although a fully enclosed protective cover can reduce the entry of chips, it may lead to excessively high internal temperature. Existing heat dissipation solutions (such as electric fans) are prone to clogging in dusty or oily environments, affecting heat dissipation efficiency and even accelerating the aging of components.

[0006] (3) Similar to the fully enclosed protection used in CNC machine tools, the production cost of the external protective device is high and the installation is relatively complicated. The visual operation of fully enclosed protection is smaller in terms of operating space and visual range compared to the open operation of ordinary lathes.

[0007] (4) The maintenance cost and complexity of fully enclosed protection are high. Protective devices (such as guide rail roller shutters and steel plate protective covers) need to be cleaned, lubricated and inspected regularly. The disassembly process is complicated and not easy to operate. Summary of the Invention
