Special jig for relieving and grinding the clearance angle of chamfering tools on cylindrical grinders

Abstract

The invention discloses a special fixture for relief-grinding a relief angle of a chamfering tool on a cylindrical grinding machine. The special fixture comprises a Morse taper shank sliding shaft (2), an axial cam (7) and an adjusting member (14). The special fixture is characterized in that a sliding sleeve (3) is mounted at one end of the Morse taper shank sliding shaft (2); a guide key (4) is disposed between the Morse taper shank sliding shaft (2) and the sliding sleeve (3); the axial cam (7) is fixed to the sliding sleeve (3); a replaceable workpiece sleeve (13) is fixed to one end of the sliding sleeve (3); a chamfering tool (12) is mounted in an inner hole of the replaceable workpiece sleeve (13); a spring (6) is disposed inside the Morse taper shank sliding shaft (2); one end of the spring (6) is fixed to the Morse taper shank sliding shaft (2), and the other end thereof is fixed to the sliding sleeve (3); a positioning sleeve (17) sleeves the sliding sleeve (3). The special fixture has the advantages that relief grinding of the relief angle of the chamfering tool is available on the cylindrical grinding machine, the fixture is simple to use, production efficiency is high, cost is low, machining quality is high, and the service life of the chamfering tool is long.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a special fixture for shoveling the back corner of a chamfering knife on an outer cylindrical grinder. Background technique [0002] The chamfering cutter is a tool that is assembled on a milling machine, drilling machine, planer, chamfering machine and other machine tools to process the 60-degree or 90-degree chamfering and tapered holes of the chamfering cutter, and it belongs to the end milling cutter. Chamfering knife is also called chamfering device. The chamfering knife has a wide range of applications, not only suitable for chamfering with ordinary machinery and chamfering knives, but also suitable for chamfering and deburring of precision difficult-to-chamfer parts. Such as: aviation, military, automotive industry oil, gas, electric valves, engine block, cylinder, sphere through hole, inner wall hole. [0003] Relief grinding the back angle of the chamferi...

Problems solved by technology

In the existing technology, the traditional method is to use a shovel grinder for processing. The price of one shovel grinder is equivalent to the price of 2 to 3 cylindrical grinders, and the equipment utilization rate is low, the productivity is low, and the processed surface is rough, and the service life of the tool is short.
