Description

Technical Field

[0001] This utility model relates to the field of machine tools, and in particular to a grinding machine tool. Background Technology

[0002] In the field of machining, grinding machine tools are key equipment for achieving high-precision surface processing of parts, and their processing accuracy and operational stability directly affect product quality. Currently, most grinding machine tools on the market have a simple sliding fit structure between the drive seat and support frame, lacking targeted reinforcement design. When the large spindle rotates at high speed to drive the cutting head for grinding, the radial runout of the cutting head is easily caused by the deformation of the drive seat, which not only reduces processing accuracy but also shortens the service life of core components. At the same time, the displacement adjustment of the worktable and drive seat mostly relies on a single guide rail structure, making it difficult to achieve precise positioning in multiple directions and failing to meet the high-precision grinding requirements of complex-shaped products.

[0003] Furthermore, grinding processes generate a large amount of waste material mixed with coolant. Existing machine tool waste disposal structures are mostly single inclined surfaces or straight grooves, resulting in incomplete waste collection and easy accumulation of waste in dead corners of the groove. Waste residue not only requires frequent manual cleaning, increasing maintenance costs, but may also get stuck in the sliding gap between the worktable and the base, affecting the worktable's sliding accuracy and even scratching equipment parts, leading to a decrease in the overall machining stability of the machine tool and making it difficult to meet the needs of long-term continuous production.

There is a gap between the support platform and the raising platform. A deep groove is recessed in the gap space between the support platform and the raising platform. The bottom wall of the deep groove is an inclined surface parallel to the rear side. The deep groove is connected to the sewage trough.

[0014] Preferably, the front side near the feed inlet of the base has a length shorter than the rear side. The bottom wall of the support platform has a clearance hole that faces the drain trough.

At the same time, the vibrating components can prevent waste from accumulating in the trough, achieving rapid and automatic discharge of waste, reducing manual cleaning costs, and preventing waste residue from affecting processing accuracy or damaging machine tool parts.
