Technical Field

[0001] This utility model relates to the field of polishing and grinding technology, specifically to an adaptive floating grinding head for polishing and grinding. Background Technology

[0002] Polishing and grinding are common surface treatment processes in industry and manufacturing. By using grinding tools (such as sandpaper, grinding wheels, and floating grinding heads) or polishing materials (such as polishing paste and abrasives), mechanical force or chemical action is applied to the surface of workpieces such as metal, plastic, and wood to remove surface defects such as burrs, scratches, and oxide layers, reduce surface roughness, and ultimately achieve a smooth, flat, or even mirror-like surface. Floating grinding heads are an advanced tool used in industrial surface treatment that can adaptively adjust the grinding position and pressure, and are widely used in the automotive, aerospace, and other fields.

[0003] However, the built-in universal joint of the existing adaptive floating grinding head is easily clogged by grinding dust, resulting in poor lubrication and increased rotational resistance, making it unable to flexibly adapt to the curved surface of the workpiece. Utility Model Content

[0004] The purpose of this invention is to provide an adaptive floating grinding head for polishing and grinding, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adaptive floating grinding head for polishing and grinding, comprising a lower grinding disc and a lubrication assembly. An upper grinding disc is provided at the upper end of the lower grinding disc. The lubrication assembly, which improves flexibility, is located inside the lower and upper grinding discs. The lubrication assembly includes a universal joint, a lubrication channel, a vertical conveying channel, a horizontal conveying channel, an oil storage box, and an oil injection hole. A lubrication channel is provided on the outer side of the universal joint, and a vertical conveying channel is connected to the top of the universal joint. A horizontal conveying channel is connected to the side of the vertical conveying channel, and an oil storage box is connected to the end of the horizontal conveying channel. An oil injection hole is provided at the top of the oil storage box.

[0006] Furthermore, an assembly rod is connected to the upper end of the upper grinding disc, and a limit plate is installed on the outside of the assembly rod. Rubber corrugated pipes are installed on the outer side of the lower grinding disc and the inner side of the upper grinding disc.

[0007] Furthermore, a floating assembly for grinding is installed on the outer side of the grinding disc, and four sets of the floating assembly are arranged in a ring about the center point of the grinding disc.

[0008] Furthermore, the floating assembly includes a metal bellows and a connecting cap, with the lower end of the metal bellows connected to the connecting cap.

[0009] Furthermore, the floating assembly also includes a threaded rod and a connecting cap, the threaded rod being installed on the internal threads of the connecting cap, and the upper end of the metal bellows being connected to the connecting cap.

[0010] Furthermore, a Velcro strap is installed at the lower end of the grinding disc, and a grinding disc is installed at the lower end of the Velcro strap.

[0011] Furthermore, a limiting component for limiting the angle compensation range is installed on the lower end of the grinding disc, and four sets of the limiting component are arranged in a ring around the center point of the grinding disc.

[0012] Furthermore, the limiting assembly includes an upper limiting rod, a limiting sleeve, and a lower limiting rod, with the lower end of the upper limiting rod fitted with the limiting sleeve, and the inner side of the limiting sleeve being provided with the lower limiting rod.

[0013] This utility model provides an adaptive floating grinding head for polishing and grinding, which has the following beneficial effects:

[0014] 1. This utility model uses vertical and horizontal conveying channels to transport lubricating oil from the oil storage box to the surface of the universal joint, which lubricates the universal joint, prevents jamming, improves flexibility, ensures adaptive floating effect during grinding, and the lubrication channels make the lubricating oil evenly distributed on the surface of the universal joint.

[0015] 2. This utility model uses a rubber corrugated tube to provide external dust protection between the lower and upper grinding discs. The metal corrugated tubes are installed on the outside of the corresponding threaded rods via connecting lower and upper caps. The two hollow threaded rods are connected by a sleeve inside the metal corrugated tube. The metal corrugated tube has a stable elastic coefficient and a long service life.
