As shown in fig. 1-2, the multi-axis integrated positioning and clamping device for the high-precision cylinder comprises a closed annular base 100, wherein the annular base 100 is provided with an inner ring and an outer ring, the inner ring is the inner part of the annular base 100, and the outer ring is the outer part of the annular base 100. The annular base 100 is provided with a plurality of mounting grooves 110, and the mounting grooves 110 are circumferentially distributed at equal intervals along the annular base 100. The mounting groove 110 penetrates the annular base 100 inward in the horizontal direction, that is, the mounting groove 110 is communicated to the inner ring of the annular base 100. A positioning cylinder 200 is arranged in the mounting groove 110, a positioning plate 300 is arranged at one end of the mounting groove 110 facing the inner ring of the annular base 100, the positioning plate 300 seals the opening of the mounting groove 110, and a piston rod 210 of the positioning cylinder 200 passes through the positioning plate 300 and extends into the inner ring of the annular base 100.
In this embodiment, a plurality of positioning cylinders 200 are installed in the installation groove 110, and the workpiece is clamped and positioned by controlling the extension and contraction of the piston rods 210 of the positioning cylinders 200. And the annular base 100 fixes the position of the positioning cylinder 200, thereby eliminating the influence of the installation precision error of the positioning cylinder 200 on the workpiece processing, improving the workpiece processing stability and improving the product processing efficiency.
The inner ring shape of the annular base 100 is adapted to the outer shape of the workpiece. For example, when the watch shell is processed, the shape of the inner ring is the center of a circle; when the mobile phone frame is processed, the inner ring is rectangular. The shape of the inner ring is customized according to the appearance of the workpiece.
In this embodiment, the inner ring has a rectangular shape. The moving directions of the piston rods 210 of the positioning cylinders 200 located at two opposite sides of the annular base 100, i.e. at two opposite sides of the inner ring, are parallel, and the moving directions of the piston rods 210 of the positioning cylinders 200 located at two adjacent sides of the annular base 100, i.e. at two adjacent sides of the inner ring, are perpendicular.
The axes of the piston rods 210 of all the positioning cylinders 200 are in the same plane. When positioning a workpiece, the piston rods 210 of all the positioning cylinders 200 can abut against the outer surface of the workpiece at the same height, so that all the positioning cylinders 200 can abut against and fix the annular workpiece.
The piston rod 210 has a hexagonal shape and is engaged with a hexagonal hole 310 formed in the positioning plate 300. The hexagonal piston rod 210 and the hexagonal hole 310 can effectively prevent the piston rod 210 from rotating, and the positioning stability is improved.

The installation groove 110 is communicated with the outer ring of the annular base 100, which facilitates the installation of the positioning cylinder 200, and after the installation of the positioning cylinder 200 is completed, the installation groove 110 is closed by the cover plate 400. In this embodiment, one cover plate 400 is disposed at one outer side of the annular base 100, that is, one cover plate 400 is shared by the mounting grooves 110 on the same side, which can improve the mounting efficiency of the positioning cylinder 200.
In three of the side surfaces of the annular base 100, the positioning cylinders 200 on the same side surface are controlled by the same air passage, and in the other side surface of the annular base 100, each positioning cylinder 200 is controlled by an independent air passage. When clamping and positioning are carried out, the positioning air cylinder 200 controlled by the same air channel on one side firstly extends out of the piston rod 210, then the positioning air cylinders 200 controlled by the same air channel on the other two sides extend out of the piston rod 210, and finally the positioning air cylinders 200 controlled by the independent air channels extend out of the piston rod 210 to abut against the outer surface of a workpiece. The positioning cylinder 200 on one side of the annular base 100 is controlled by an independent air path, so that the device provided by the embodiment can process a rectangular workpiece with a slightly irregular side.
