Technical Field
The invention relates to a circular saw blade gear grinding machine, in particular to a self-centering clamp of the saw blade gear grinding machine.
Technical Field
The hard alloy circular saw blade is widely applied to aluminum cutting, wood cutting and steel cutting, wherein the hard alloy saw blade for cutting steel, also called a cold saw, has the highest requirement on processing equipment, and generally requires the precision of a finished product processing position to be within 0.01 mm. The circular saw blade gear grinding machine is a special grinding machine for grinding a hard alloy cutter head welded on a saw blade, and can lead the cutter head to bounce and break due to uneven stress when the saw blade is subjected to grinding force of a grinding wheel in the grinding process for preventing the saw blade from generating displacement when the saw blade is subjected to the grinding force of the grinding wheel, so that each circular saw blade must be compressed tightly at a fixed position when the circular saw blade is ground according to teeth.
The existing saw blade gear grinding machine adopts a direct-drive hydraulic cylinder to carry out compression and positioning on a saw blade, one side of the clamping mechanism is a fixed end, the other side of the clamping mechanism is a hydraulic cylinder end, and because a grinding head of the grinding machine is fixed and nonadjustable along the axial direction of the saw blade for keeping better rigidity, the thickness center of the saw blade needs to be aligned with the axis of a grinding wheel when the saw blades with different thicknesses are replaced, the positions of the fixed sides are manually adjusted to be aligned at present, and the precision is not high. In particular, the thickness deviation of the saw blade plate is not a standard plane but is generally 0.01-0.04mm in the machining process, and the deviation can also be reflected to the alloy tool bit of the saw teeth, so that the precision of the saw blade is deteriorated, and the service life and the smoothness of the section bar are influenced.
Disclosure of Invention
The invention aims to provide a self-centering clamp of a saw blade gear grinding machine, which is simple in structure, so that the machining precision of the grinding machine is improved, and errors caused by manual adjustment are avoided.
