Description
技术领域technical field
本实用新型涉及数控机床设备领域，尤其涉及一种机械加工快速定位夹具平台。The utility model relates to the field of numerical control machine tool equipment, in particular to a fast positioning fixture platform for machining.
背景技术Background technique
铸铁T型槽平台又叫T型槽平板，一种表面带有T型槽的铸铁平板，用于固定工件，装配、调试机械设备的基础工作平面。由于工作台面上通常只有单方向的T型槽，造成另一方向可移动的空间较少，即，现有T型槽的装夹工位灵活度还有待提升。Cast iron T-slot platform, also known as T-slot plate, is a cast iron plate with T-slots on the surface, which is used to fix workpieces, and is the basic working plane for assembling and debugging mechanical equipment. Since there are usually only T-shaped slots in one direction on the worktable, there is less space for movement in the other direction, that is, the flexibility of the clamping station of the existing T-shaped slots needs to be improved.
为改进现有T型槽平台的灵活度，中国专利号200620166708.5的实用新型专利公开了一种用于数控机床的快速定位的机床工作台，在工作台面每两个T形槽之间均匀设置横向与T形槽平行，纵向与T形槽垂直的基准孔，基准孔与工作台面相垂直；两基准孔之间开有与T形槽相垂直的基准槽。该专利对T型槽平台的改造虽然实现了准确方便地进行零件的多次或重复装夹，并且对不同的工件均可以快速的限位，但纵横交错的T形槽造成平台的刚性下降。In order to improve the flexibility of the existing T-slot platform, the utility model patent of Chinese Patent No. 200620166708.5 discloses a machine tool workbench for fast positioning of CNC machine tools. Parallel to the T-shaped slot, the longitudinal reference hole is perpendicular to the T-shaped slot, and the reference hole is perpendicular to the worktable; a reference slot perpendicular to the T-shaped slot is opened between the two reference holes. Although the transformation of the T-slot platform in this patent enables accurate and convenient multiple or repeated clamping of parts, and can quickly limit the position of different workpieces, the rigidity of the platform is reduced due to the crisscross T-slots.
