Description

Technical Field

[0001] This utility model relates to the field of cylindrical grinding machine technology, and specifically to a cylindrical grinding machine fixture. Background Technology

[0002] An external cylindrical grinding machine is a type of grinding machine used for machining the outer cylindrical surface of workpieces. It is primarily used for grinding cylindrical, conical, or other shaped surfaces formed by generatrices, as well as the end faces of shaft shoulders. It achieves cutting by rotating a grinding wheel, while the workpiece is supported and rotated by a headstock and tailstock, thus realizing high-precision, high-surface-quality external cylindrical machining. It is widely used in the machinery manufacturing industry, especially suitable for machining small and medium-sized workpieces, and can meet the machining needs of various materials and different precision requirements.

[0003] The applicant discovered through a search that a Chinese patent, "An Automatic Fixture for an External Cylindrical Grinding Machine," with publication number "CN212553337U," includes a mounting base with threaded fixing screws. The mounting base has a groove at its upper end, and guide rods are fixedly connected to the inner walls of both sides of the groove. Guide seats are movably mounted on both sides of the guide rods, and threaded seats are fixedly connected to the upper ends of the guide seats. The threaded seats are threaded onto a threaded post, and rotating motors are movably mounted on both sides of the threaded post. A threaded rotating shaft is fixedly connected to the side of the threaded post away from the rotating motors. A fixing plate is provided at the upper end of the threaded seat, and an adjusting device is provided at the upper end of the fixing plate. The adjusting device includes a slide rail, a slider, and a mounting frame. The mounting frame is fixedly mounted on the upper end of the fixing plate, and both ends of the slide rail are fixedly connected to the inner walls of the mounting frame. A slider is movably mounted on the outer end of the slide rail. This design enables automatic workpiece fixing using a fixture and improves the fixture's fixing effect.

[0004] The quarter-circular through slots on the first and second clamping blocks form a semi-circular through slot. This design may only be suitable for cylindrical or near-cylindrical workpieces. For irregularly shaped or non-circular workpieces, the fixture may not be able to effectively clamp and position them, thus limiting its applicability. Utility Model Content
