Grinding and polishing device and grinding and polishing machine

Abstract

The invention discloses a grinding and polishing device and a grinding and polishing machine. The grinding and polishing device and the grinding and polishing machine are used for grinding and polishing the peripheral face of a cylindrical workpiece rotating around the axis of the workpiece. The grinding and polishing device comprises a knife rest, a driving shaft, a driven shaft, a main motor and a grinding tool. The driving shaft and the driven shaft are coaxially and oppositely arranged on the knife rest, and the main motor drives the driving shaft to rotate. The grinding tool comprises a knife shaft installed between the driving shaft and the driven shaft and a cylindrical grinding wheel fixedly arranged on the knife shaft. The outline of the peripheral face of the cylindrical grinding wheel is meshed with the outline of the peripheral face of the cylindrical workpiece. When the grinding and polishing device works, the knife shaft and the cylindrical workpiece are arranged in parallel, and the grinding wheel can be attached to the peripheral face of the cylindrical workpiece in a seamless manner to carry out grinding and polishing.

Description

technical field [0001] The invention relates to the field of stone processing, in particular to a grinding and polishing device and a grinding and polishing machine for grinding and polishing cylindrical stones.

Problems solved by technology

[0002] In the field of stone processing, it is often necessary to grind and polish the stone surface, while cylindrical stone, especially cylindrical stone with variable diameter, such as stone railings, usually adopts manual grinding and polishing, which has low processing efficiency and high labor intensity. , poor grinding and polishing effects, etc., in view of the above problems, the patent No. ZL201320129249.3 provides a vibrating polishing equipment for stone surface polishing, including a frame, a workpiece rotating clamping mechanism, and a vibrating abrasive mechanism. It includes the left column, the right column, and the walking device installed at the bottom of the left and right columns to drive the movement of the rack; the workpiece rotation clamping mechanism includes a beam that can be vertically lifted along the left and right columns, a vertical drive device that drives the beam to lift, and a setting The workpiece clamping arm on the beam, and the lateral movement driving device that drives the workpiece clamping arm to move left and right on the beam; the vibrating abrasive mechanism is located between the left and right columns, below the workpiece rotating clamping mechanism, including several horizontally arranged Abrasive Box and Abrasive Box Drive

The workpiece is rotated in the abrasive for grinding and polishing, which can be applied to stone workpieces with different curves. It can be polished step by step through different abrasives, and the polishing effect is good at one time. However, the above equipment needs to put the workpieces into each abrasive box in turn. Grinding and polishing, the efficiency of grinding and polishing is low, and the equipment occupies a large space and the cost is high
