Floating grinding device for multi-specification castings

Abstract

The invention discloses a floating grinding device for multi-specification castings. The floating grinding device comprises a first frame, a feeding mechanism, a lower sliding base, an upper sliding base, an elastic mechanism, a main motor, a rotating shaft box, a first rotating shaft, a grinding wheel, a dust collecting mechanism, a second frame, a sliding plate, a floating mechanism, a speed reduction motor, a lifting cylinder, a transition plate, a guide base, a downwards-pressing cylinder, a pressing rod, a servo motor, a speed reducer, wheel discs, a pressure disc mechanism and a V-ribbedbelt conveyor. The floating grinding device can realize automatic feeding of the grinding wheel as well as automatic clamping and automatic grinding of the castings and can discharge smoke dust and waste scraps generated in grinding; by a floating type design, an external force is effectively prevented from interfering the motion of a second rotating shaft, so the motion steadiness is improved and the service life is prolonged; the elastic mechanism can make the upper sliding base be in a floating state so as to effectively balance the impact generated by a feeding motion; a plurality of wheel disc mechanisms are arranged, and a plurality of different specifications of pressure discs can be installed when different specifications of castings need to be pressed, so the pressure discs neednot to be dismounted frequently, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a floating grinding device for multi-standard castings. Background technique [0002] The brake disc is the rotating element in the friction pair of the disc brake. Its shape is a metal disc that works on both ends. The brake disc is generally produced by casting. After the casting is poured, there will be a lot of flashes and pouring For the riser, these flashes and pouring risers must be removed. For iron castings, it is generally knocked off directly with an oil hammer, while steel castings need to be cut off by gas cutting, and then the remaining flashes and pouring risers on the castings are removed by the casting grinder. The mouth is polished clean, smooth and beautiful. At present, electric grinders are generally used for grinding. There are fixed large grinding wheel diameter grinding machines, and there are also portable movable small grinding wheel diameter grinding machines. Bec...

[0002] The brake disc is the rotating element in the friction pair of the disc brake. Its shape is a metal disc that works on both ends. The brake disc is generally produced by casting. After the casting is poured, there will be a lot of flashes and pouring For the riser, these flashes and pouring risers must be removed. For iron castings, it is generally knocked off directly with an oil hammer, while steel castings need to be cut off by gas cutting, and then the remaining flashes and pouring risers on the castings are removed by the casting grinder. The mouth is polished clean, smooth and beautiful. At present, electric grinders are generally used for grinding. There are fixed large grinding wheel diameter grinding machines, and there are also portable movable small grinding wheel diameter grinding machines. Because the specifications of the brake disc are often not uniform , the brake discs of different models are often different, which brings great inconvenience to production, and the current grinding is basically manual operation, which is not only inefficient, but also dangerous in the operating environment
