Description

Technical Field

[0001] The utility model relates to the technical field of stone polishing, in particular to a swing mechanism assembly and a polishing machine thereof. Background Art

[0002] In stone processing, the surface of the stone needs to be polished to achieve a bright and beautiful effect. When polishing the stone slab, water should be added for lubrication and to wash away the stone powder generated by polishing. At the same time, water can also take away the high temperature generated by grinding, making the polishing effect better. Therefore, when the grinding head is rotating, water should be injected between the grinding head and the stone slab. Because the area of ​​the stone is relatively large, the grinding and polishing equipment is relatively large, so multiple grinding heads will be installed on the equipment. In order to make the processing range of the equipment larger and to allow the stone slab to be smoothly placed between the grinding head and the machine tool, the grinding head also needs to have a lifting function. Some devices on the market Equipment that is equipped with multiple grinding heads for simultaneous lifting or a supporting mechanism under the machine tool for lifting has its disadvantages. For equipment that lifts multiple grinding heads at the same time, multiple grinding heads need to be lowered each time processing, but the area of ​​some stone slabs is not very large, which will make the lowered grinding heads hinder the production personnel from observing the stone slabs, and there is also the risk of the grinding heads hitting the components and being damaged when they are lowered. The mechanism that sets a supporting mechanism under the machine tool for lifting requires a driving mechanism with a large lifting force due to the heavy weight of the stone, and the stone slab is prone to shaking during the rising and lowering process, and it is easy to crack if the stone slab is thin.

[0003] The technical content disclosed in the Chinese patent document (application number: CN201510050202.1, patent name: A quartz plate polishing machine) is: A quartz plate polishing machine, including a base, a conveyor belt arranged on the base for conveying quartz plates, and a grinding assembly is arranged above the conveyor belt, characterized in that: both ends of the base are provided with beams that cross the base in the width direction, and both beams are provided with rotating mechanisms, and the rotating mechanisms include an active rotary arm rotating on the beam, and a driven rotary arm connected to the active rotary arm at one end, and the two ends of the frame of the grinding assembly are respectively connected to the other end of the driven rotary arm, and a rotating drive motor is arranged on the beam, and the grinding assembly can swing in a curve on the upper surface of the base under the drive of the rotating mechanism. The quartz plate polishing machine of the present invention has the characteristics of high production efficiency and good polishing effect during the quartz plate polishing process.

[0004] It can be seen from the above implementation scheme that the stone slab polishing machine is provided with a grinding assembly above the conveyor belt, and the grinding assembly can be moved on the square of the stone slab. The grinding assembly is not provided with a mechanism that can be lifted and lowered separately. Therefore, each time the stone slab is placed on the conveyor belt, the grinding assembly must be moved to one side. After the stone slab is placed, the grinding assembly can be removed for grinding. Since the area of ​​the stone slab is generally large, the time when the grinding assembly moves idly will reduce production efficiency. In addition, the grinding assembly cannot be automatically lifted and lowered. When the thickness of the stone slab changes, the height of the grinding assembly needs to be manually adjusted, which brings inconvenience to the user. Utility Model Content
