Description

Technical Field

[0001] The utility model belongs to the technical field of parts of a stone cutting machine, and particularly relates to a cutter head device on a stone cutting machine. Background Art

[0002] For large stone cutting machines, such as gantry stone cutting machines, etc., the cutter head device therein is installed on the cross beam of the stone cutting machine. The cutter head device moves back and forth along with the cross beam, and the cutter head device moves horizontally left and right, moves up and down, and rotates around the vertical axis on the cross beam, constituting the three-dimensional movement of the xyz axis of the cutter head device. Usually, a disc-shaped large saw blade is used for cutting, and the disc-shaped large saw blade is installed on the cutter head device and moves in three dimensions along the xyz axis together.

[0003] At present, the saw blade is usually arranged vertically, and the cutting angle is fixed. As a result, the cutting surface formed after cutting is usually a vertical surface. When splicing two cut stone slabs later, since filler needs to be put into the gap for caulking treatment or sealing treatment, etc., and a gap needs to be left due to thermal expansion and contraction, etc., it does not result in the two vertical surfaces being easily vertically aligned, horizontally aligned, and airtight as imagined. Instead, problems such as vertical misalignment, horizontal misalignment, difficulty in filling and sealing, or bulging and cracking at the later joint occur easily.

[0004] Therefore, how to adjust the cutting angle of the saw blade during the stone cutting process by referring to the principle of cutting the bevel of the groove before welding, so as to cut out a bevel similar to the welding groove, mainly solve the joint problem during the stone splicing, make the splicing more natural without any abrupt feeling, is a technical problem that needs to be urgently solved by those skilled in the art.

[0041] This application provides a tool head device on a stone cutting machine, including a tool head holder 1, a motor 201, a motor mounting base 202, a saw blade 203, a lifting cylinder 204, a cylinder base 205, and an eccentric swing shaft 206 (damping rotating shaft);

[0042] The tool head holder 1 is used to be mounted on the cross beam of the stone cutting machine, and the tool head holder 1 moves horizontally left and right, moves up and down, and rotates around the vertical axis on the cross beam;

[0043] The motor 201 is installed on the motor mounting base 202, and the motor 201 is located below the motor mounting base 202. The motor 201 is arranged in a horizontal posture. The saw blade 203 is installed on the output shaft of the motor 201, and the length and width surfaces of the saw blade 203 are perpendicular to the axis of the output shaft of the motor 201;

The cylinder barrel of the lifting cylinder 204 is arranged on the cylinder base 205. The piston rod of the lifting cylinder 204 is vertically upward, and the top end of the piston rod of the lifting cylinder 204 contacts the lower surface of the motor mounting base 202 (only simple contact rather than mechanical connection such as hinge connection) to drive the tail of the motor mounting base 202 to rotate upward when the piston rod of the lifting cylinder 204 extends and drive the tail of the motor mounting base 202 to rotate downward when the piston rod of the lifting cylinder 204 retracts (entirely due to the eccentric self-weight of the motor mounting base 202 and the eccentric self-weight of the motor 201 to rotate downward). Furthermore, the articulated rotation of the motor mounting base 202 drives the motor to swing and the saw blade to swing (the swing adjustment of the cutting angle between the motor 201 and the saw blade 203).

[0049] The milling cutter (not shown in the drawings) is sleeved and inserted and fixed in the tool chuck at the bottom end of the motorized spindle (the cylindrical protruding shape at the bottom end of the motorized spindle in the drawings is the tool chuck).
