Description
Technical Field
The utility model relates to a saw bit gear grinding machine, especially a saw bit gear grinding machine is from centering anchor clamps.
Background
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.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose just, provides a simple structure's saw bit gear grinding machine is from centering anchor clamps, improves the machining precision of grinding machine and avoids the error of manual regulation production.
In order to achieve the above purpose, the present invention is provided with a cylinder seat 2 and a wire gauge 13 in a frame 1, lever supports 10 are provided on both sides of the frame 1, and a pair of a chuck seat 7 and a connecting rod shield are provided on the top of the frame 1.
The cylinder seat 2 is provided with a large cylinder 12 and a small cylinder 3 in parallel, the small cylinder is internally provided with a spring, the tops of the two cylinders are provided with a push head 4, the push head 4 is connected with the lower end of a lever 9 through a main connecting rod 11, and the lever 9 is connected with a chuck 6 through a lever support 10 and an auxiliary connecting rod 8. The inner side of the push head 4 is connected with a wire gauge 13. The main connecting rods 11, the levers 9, the auxiliary connecting rods 8, the chucks 6 and the chuck seats 7 are symmetrically arranged in two sets.
