Corner type main shaft

Abstract

The invention discloses a corner type main shaft, which comprises a saddle unit, a main shaft unit, an output unit and a transmission unit, wherein the saddle unit is provided with an outer pipe body which is extended along a first axial direction and a positioning piece which is arranged at the front end of the outer pipe body; the main shaft unit is arranged in the saddle unit and is provided with a power source, an inner pipe body which is extended into the outer pipe body and a first central shaft which is arranged in the inner pipe body; the output unit is provided with a seat body whichcan be detachably arranged on the positioning piece and a second central shaft which is arranged on the seat body along a second axial direction; the first central shaft is provided with a first mounting part which is protruded out of the inner pipe body; the first mounting part is provided with a preparation tool section which is positioned in the outer pipe body; the second central shaft is provided with a second mounting part which is protruded out of the seat body and a relay mounting section which is positioned in the seat body; the second mounting part is provided with an active tool section; and the transmission unit is provided with a first transmission piece which is arranged on the first mounting part and extended into the seat body and a second transmission piece which is arranged in the relay mounting section and driven by the first transmission piece.

Description

technical field [0001] The invention relates to a main shaft of a tool machine tool, in particular to an angle-type main shaft suitable for various configurations. Background technique [0002] Grinding machine is an indispensable machine tool for precision grinding of mechanical parts and knives. Grinding machines can be broadly divided into cylindrical grinding machines and surface grinding machines according to the type of workpiece clamping. Cylindrical grinding machines are suitable for internal and external diameter grinding, chamfering and taper grinding of workpieces. For related machine structures, please refer to the patent document Taiwan, China M363360 The surface grinder is suitable for surface grinding of the workpiece. Among them, the medium and large surface grinder uses a gantry structure for the two-dimensional feeding of the grinding wheel spindle. For the relevant machine structure, please refer to the patent documents China Taiwan M334766, China Taiwan M...

AI Technical Summary

Problems solved by technology

Its disadvantage is that the drive mechanism and grinding wheel are installed in a suspension frame outside the column, and its structure is too large and complex, resulting in an excessively high center of gravity, increased bending moment load of the column, and poor balance

[0006] Three, the third type of small and medium-sized surface grinder, its main shaft adopts vertical configuration, such as the sub-spindle disclosed in the patent document China Taiwan 00275827, which is suitable for grinding operations with special inclination angles (such as dovetail grooves), but its disadvantages are the same as those of the second type , so it is necessary to add a counterweight device for balance

[0007] It can be seen from the above that the combination of the second and third small and medium-sized surface grinders with the first kind of small and medium-sized surface grinder can make the processing more comprehensive, but the spindle structure design of the second and three small and medium-sized surface grinders cannot follow the first one. It is a pity that the spindles of small and medium-sized surface grinders have matured. Moreover, for manufacturers of machine tools and spindles, there are problems of complicated production management and high costs. In addition, for users, it is impossible to The existing first type of small and medium-sized surface grinder is transformed into the second and third types of small and medium-sized surface grinders. There are troubles in purchasing the whole machine and re-adapting to the characteristics of different machines.
