Description

Floating type power head for processing artificial stone plate Technical Field The utility model relates to the technical field of post-treatment of artificial stone plates, in particular to a floating power head for artificial stone plate processing. Background In the field of stone processing, in particular to a post-treatment process of artificial stone table boards such as kitchen wash-stands and the like, various functional hole slots are often arranged in the boards, including basin holes for embedding bowls and basins, furnace holes for installing gas stoves, tap holes for fixing taps and the like. In addition, the outer edge of the plate needs to be finely processed according to design requirements, such as curve, oblique line or irregular contour cutting required by a special modeling table top. To ensure smooth transition between the edges of the slot and the mounting component (e.g., a hand basin), the edges of the basin or stove holes are also rounded or chamfered. During processing, the artificial stone slab is generally horizontally fixed on a workbench, and cutting operation is completed by a power head according to a preset path and size. The current mainstream driving scheme mostly adopts a multi-degree-of-freedom mechanical arm or an XYZ three-dimensional linear driving system, and the mechanical structure of the current mainstream driving scheme is based on a portal frame, a column-beam combination or a slide rail-slide rail unit, and belongs to the industry general technology. However, the prior art has the following limitations: (1) The motion dimension is limited in that the drive mechanism supports only linear motion in a single direction. For example, when a rectangular basin hole is machined, the power head needs to alternately move along the transverse direction or the longitudinal direction, and multi-directional compound movement cannot be realized; (2) The grinding and cutting terminal is low in replacement efficiency, namely the grinding and cutting terminal (such as a cutting tool bit and a grinding head) carried by the power head needs to be manually disassembled and replaced, so that the requirement of multi-station continuous processing is difficult to meet; (3) The problem of structural interference is prominent, and when the basin hole/furnace hole is internally modified, the moving range is directly influenced by the oversized power head. The existing power head is mainly provided with a three-jaw clamp matched with a universal interface to fix a grinding and cutting terminal, and a driving motor and a power head rotating shaft are coaxially designed, so that the whole axial dimension is redundant, and the operation flexibility in a narrow space is limited. Disclosure of utility model The utility model aims to provide a floating type power head for processing an artificial stone slab, which aims to solve the technical problems of limited movement dimension, low replacement efficiency of a grinding and cutting terminal and outstanding structural interference of the existing artificial stone slab power head.
