Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to a numerically controlled lathe with a safety device. Background Art

[0002] With the rapid development of modern manufacturing, the requirements for machining accuracy, efficiency and product quality are increasing. CNC lathes, as key equipment in the field of machining, can realize automated and high-precision workpiece processing, which greatly meets the manufacturing industry's demand for efficient production of complex parts. However, during the operation of CNC lathes, their high-speed rotating spindles, fast-moving tools and flying chips all have certain safety hazards, which may cause personal injury to operators and may also cause equipment damage due to accidents, thereby affecting production progress. In order to ensure the safety of operators and the normal operation of equipment, equipping CNC lathes with safety devices has become an inevitable development trend.

[0003] Prior art includes a utility model with publication number CN214445006U, which discloses a CNC lathe with a safety device. The patent utilizes a main body with a protective door connected to one side of the main body's outer wall, a connecting block welded to the inner wall of the protective door, and a second electric telescopic rod mounted on the inner wall of the main body, connected to the connecting block. A glass window extending from the outer side of the protective door to the inner side of the protective door is provided, and glass is installed inside the glass window. A brush extending into the interior of the protective door is provided on the inner surface of the glass, and a first electric telescopic rod is mounted on the bottom end of the brush located inside the protective door. The utility model provides a brush and an electric telescopic rod. When the first electric telescopic rod is activated, the brush moves along the inner surface of the glass, removing iron filings adhering to the inner surface of the glass. This allows workers to clearly observe the interior of the main body, avoids tool collisions, and prolongs the service life of the equipment. This solves the problems of the prior art, such as the inability to adjust the operating table pedal height according to individual height and the inability to clean iron filings adhering to the inner surface of the protective door glass.

[0004] In the process of using CNC lathes with safety devices in daily life, the existing structure with safety devices is likely to affect the chip removal effect of the CNC lathe. The sealing structure of the protective door may hinder the discharge of chips, causing chips to accumulate in the processing area, affecting the processing accuracy and the normal operation of the equipment. Long-term chip accumulation may also cause damage to the safety device itself, resulting in the need to increase maintenance costs. Utility Model Content
