Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, and in particular to a portable stone chamfering polishing machine. Background Technology

[0002] In the stone industry, there are two main ways to polish stone: one is manual polishing, and the other is using traditional stone polishing machines.

[0003] After stone is cut and processed, its edges and corners are relatively sharp, which affects its appearance and makes it easy to be damaged. It is necessary to grind the edges and corners of the stone to create chamfers, so as to improve the appearance of the stone and ensure that the edges of the stone are not bumped or damaged.

[0004] Therefore, a portable stone beveling and grinding machine is proposed for beveling and grinding the edges of stone.

[0005] Existing stone beveling and grinding machines only have a handle for holding and grinding the edges of the stone, which is inconvenient to carry and move. Moreover, when carrying the grinding machine, the grinding discs are quite sharp and can easily scratch or damage external objects, which is both unsafe and can easily damage the grinding machine, making it inconvenient to carry the grinding machine safely. Utility Model Content

The protective mechanism includes a protective cover, a bottom cover, a locking mechanism, and a buffer mechanism. The protective cover slides over the outer side of the polishing disc, the buffer mechanism is mounted on the top of the protective cover, the locking mechanism is mounted on the bottom outer side of the protective cover, and the bottom cover is mounted on the bottom of the protective cover and connected to the locking mechanism. The buffer mechanism includes a connecting plate, a first guide rod, and a first spring. The surface of the connecting plate has a first guide hole. The bottom end of the first guide rod is fixed to the top end of the protective cover and slides through the first guide hole. The first spring is sleeved on the surface of the first guide rod, and a first nut is connected to the top end of the surface of the first guide rod.

[0009] Furthermore, the snap-fit ​​mechanism includes a snap-fit ​​cylinder and a snap-fit ​​block. The snap-fit ​​cylinder has a insertion groove in the middle, and telescopic grooves are formed in the middle of both sides of the insertion groove. A second guide hole is formed at the outer end of the telescopic groove. The snap-fit ​​block is slidably installed inside the telescopic groove.

[0012] Furthermore, a lifting handle is fixed to the top of the grinding head, the handle is horizontally positioned, the grinding head is vertically positioned, the grinding disc is horizontally positioned, and the protective cover is a cylindrical structure and is vertically positioned.

[0013] Furthermore, the bottom cover has a circular structure and is horizontally positioned at the bottom end of the grinding disc; the connecting plate has an annular structure and is horizontally positioned below the handle; the first guide rod is vertically positioned; and the first spring is located between the connecting plate and the protective cover.

[0014] Furthermore, the snap-fit ​​cylinder has a cylindrical structure and is vertically fixed to the outside of the protective cover. The insertion groove and the second guide hole are both circular holes. The second guide hole is horizontally positioned. The telescopic groove has a rectangular groove structure and is horizontally positioned. The limiting plate is located at the outer end of the second guide hole.

When the grinding machine is chamfering the edges of stone, the protective cover can cover the outside of the grinding disc, reducing dust and debris dispersion and improving grinding safety. The height of the protective cover can also be flexibly adjusted. Furthermore, when carrying the grinding machine, the protective cover can cover the outside of the grinding disc, separating the grinding disc from the outside environment. This prevents the grinding disc from being bumped or damaged and from scratching external objects, thus improving the safe portability of the grinding machine.

[0018] 2. In this utility model, the bottom cover can be detachably installed at the bottom of the protective cover through a snap-fit ​​mechanism. Therefore, when carrying the grinder, the bottom cover can be installed at the bottom of the grinding disc through the plug rod. The grinding disc is sealed and protected by the protective cover and the bottom cover, which can prevent rainwater from getting it wet when carrying it, or when storing the grinder, the grinding disc is in the sealed space between the protective cover and the bottom cover, which reduces the corrosion of dust and moisture and improves the safety of the grinding disc.
