Milling cutter for heavy spherical shell grinding machine

Abstract

The invention discloses a milling cutter for a heavy spherical shell grinding machine, and relates to the technical field of hardware machining. The milling cutter for the heavy spherical shell grinding machine comprises a cutter holder, the bottom end of a cutter head is clamped in the cutter holder, a containing cavity is formed in the cutter holder, an oil removal mechanism is arranged in the containing cavity, a plurality of heat collection mechanisms distributed at equal intervals along the axis of the cutter holder are arranged in the oil removal mechanism, the oil removal mechanism comprises a flexible film, a movable rod, a magnetic ball, an arc-shaped hollow plate, a first magnetic bead, a first balloon, a hemispherical sponge and a second balloon, and the upper side and the lower side of the flexible film are bonded to the upper side and the lower side of the inner wall of the containing cavity correspondingly. According to the milling cutter for the heavy spherical shell grinding machine, through the oil removal mechanism arranged between the cutter holder and the cutter head, an oil film between the cutter holder and the cutter head can be continuously cleaned in the working process of the milling cutter, and then the situation that the clamping effect borne by the cutter head is reduced due to the fact that the oil film is accumulated between the cutter holder and the cutter head is prevented.

Description

technical field [0001] The invention relates to the technical field of hardware processing, in particular to a milling cutter for a heavy-duty spherical shell grinder. Background technique [0002] A milling cutter is a rotating tool with one or more teeth for milling. When working, each knife tooth cuts off the allowance of the workpiece intermittently in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines. [0003] During the working process of the milling cutter, due to the oil film between the inner hole of the tool holder and the outer surface of the milling cutter handle, it is very easy to cause the milling cutter to gradually protrude from the tool holder and eventually fall off during the milling process, resulting in the scrapping of the workpiece. The use of non-water-soluble cutting oil during cutting will also cause an oil film to form inside the tool holder, which has a gr...

[0003] During the working process of the milling cutter, due to the oil film between the inner hole of the tool holder and the outer surface of the milling cutter handle, it is very easy to cause the milling cutter to gradually protrude from the tool holder and eventually fall off during the milling process, resulting in the scrapping of the workpiece. The use of non-water-soluble cutting oil during cutting will also cause an oil film to form inside the tool holder, which has a great impact on normal milling
