Description

Technical Field

[0001] This utility model relates to the technical field of CNC machine tool accessories, specifically a spindle protection plate structure for CNC machine tools. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system logically processes programs with control codes or other symbolic instructions, decodes them, represents them with coded numbers, and inputs them into the CNC device via an information carrier. After processing, the CNC device sends various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] However, the spindle structure of traditional CNC machine tools does not have a protective structure, and the chips generated during the cutting process are easily splashed onto the transmission mechanism of the spindle structure, which causes accelerated wear and affects the service life of the CNC machine tool and increases daily maintenance costs. Therefore, this utility model proposes a spindle protection plate structure for CNC machine tools to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a spindle protection plate structure for CNC machine tools to solve the problems mentioned in the background art.

An inspection port is provided on the lower rear side of the protective cover, and a connecting ear plate is formed by bending at the inspection port position. A Z-axis transmission mechanism is fixedly installed on the X-axis moving part on the inner side of the protective cover. A Z-axis moving part is installed on the Z-axis transmission mechanism. A tool drive structure is installed on the Z-axis moving part. The tool drive structure passes through a through hole on the lower side of the protective cover, and the through hole on the lower side of the protective cover matches the outer diameter of the tool drive structure.

[0007] The rear cover plate is fixed to the connecting ear plate on the rear side of the protective cover by positioning screws.

[0008] The bellows cover has an upper guide seat and a lower guide seat fixedly installed on the upper and lower sides of the frame of the CNC machine tool, respectively. The upper and lower ends of the bellows cover are movably mounted on the upper and lower guide seats, respectively. Connecting plates are fixedly connected to both sides of the bellows cover. The connecting plates on both sides of the bellows cover are connected to the protective covers on both sides of the bellows cover, and the connecting plate on the outermost edge of the protective cover is connected to the frame of the CNC machine tool.

[0009] Preferably, the connecting plate has a U-shaped slot, and the side wall of the protective cover has a rotating hole. The rotating hole is corresponding to the U-shaped slot, and a rotating shaft is rotatably installed in the rotating hole. A locking block is fixedly welded to the outer end of the rotating shaft, and a force-bearing block is integrally formed on the inner end of the rotating shaft. When the bellows cover is actually installed, the locking block is locked at the port of the U-shaped slot.

[0010] Preferably, a top rod is fixedly welded to the inner side of the rear cover plate, and a through hole is provided on the connecting ear plate at the inspection port position. The through hole is aligned with the top rod, and the top rod passes through the through hole during actual installation of the rear cover plate.

[0011] Preferably, when the force-bearing block rotates to a horizontal angle, the locking block is engaged at the port of the U-shaped slot.

When the force-bearing block and the lower stop block are in contact, the force-bearing block is in a horizontal state, and when the rear cover is actually installed, the top rod abuts against the upper surface of the force-bearing block.

[0013] Preferably, when the force-bearing block and the upper stop block are engaged, the locking block and the U-shaped locking groove are aligned.

[0014] Preferably, the inner side of the card block is provided with a magnetic groove, and a magnetic block is fixedly glued in the magnetic groove. The connecting plate and the protective cover are both made of ferromagnetic material.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

By setting up a spindle protection plate structure composed of a protective cover, a rear cover plate, and a bellows cover, the Z-axis transmission mechanism is protected by the protective cover and the rear cover plate, and the retractable bellows cover can effectively protect the X-axis transmission mechanism. This effectively prevents the flying chips generated by the machining head from damaging the transmission mechanism on the CNC machine tool, thereby effectively improving the service life of the transmission mechanism and reducing the daily maintenance cost of the equipment.
