Description

Technical Field

[0001] The utility model relates to the technical field of stone polishing, in particular to a grinding head upper assembly. 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: CN201620074559.3, patent name: A stone polishing grinding head structure) is: The utility model provides a stone polishing grinding head structure, including a body, a water outlet, a muffler, a water flow box arranged in the middle position of the support rod, a water flow pipe arranged on the lower end surface of the water flow box, a water outlet arranged at the upper end of the grinding head, a muffler arranged in the middle position of the grinding head, one end of the muffler arranged on the outer surface of the grinding head, and a sponge arranged at the bottom end of the grinding head. Compared with the prior art, the utility model has the following beneficial effects: by arranging a water flow box on the body, water flows through the water flow box to the water flow pipe to reach the water outlet, and water flows out of the water outlet continuously through the water outlet, thereby solving the traditional water filling problem, and by arranging a muffler in the middle of the grinding head, the problem of noisy sound when the staff is working is solved, and by arranging a sponge at the bottom end of the grinding head, the sponge absorbs impurities, dust and dirt oil in the grinding head, thereby solving the problem of serious wear of the grinding head, saving costs, and the utility model is cleverly designed and improves market competitiveness.

[0004] It can be seen from the above implementation scheme that the stone polishing grinding head is provided with a water outlet, which can automatically inject water when polishing the stone, but there is no separate grinding head lifting mechanism, and the lifting of the grinding head cannot be individually controlled, and the number of grinding heads for processing plates of different sizes cannot be set. In addition, if the grinding head cannot be lifted, the stone slab needs to be lifted and lowered, and a driving mechanism with greater lifting force is required during processing, which increases the cost of the equipment.

When the plate is inserted into the machine tool, the grinding head rises. When processing the plate, the number of grinding heads to be lowered can be set according to the size of the plate and the placement position. Moreover, the main shaft can also rotate while moving up and down. Therefore, when the main shaft needs to rise and fall in the middle of processing, there is no need to wait for the grinding head to stop rotating, which greatly improves the processing efficiency.
