Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Refering to fig. 1, a kind of worm gear arc machining cutter, by the first cutter hub 1, straight pin 2, the second cutter hub 3, cutter head 4 and behaviour
Make the composition of handle 5, the circular arc for machining worm wheel.Shown in first cutter hub 1(Fig. 2) it is second level hierarchic structure, section is square,
The front end of first cutter hub 1 is machined with vertical axis hole 1-1, installs cylindrical sleeve 1-2, cylindrical sleeve 1-2 and the first cutter hub in axis hole 1-1
1 welding or interference connection, the front end face of the first cutter hub 1 are arc surface, and the first cutter hub 1 is for entire cutter clamping in knife rest.
Straight pin 2 is stepped shaft structure (shown in Fig. 3), and the diameter of 2 lower part of straight pin is less than the diameter on straight pin top, circle
The lower part of pin 2 is mounted in cylindrical sleeve 1-2, and straight pin 2 and 1 shape of the first cutter hub are in the hinge connection, and straight pin 2 can be in cylinder
Cover rotation in 1-2.The top of straight pin 2 is machined with the mounting hole 2-1 of radial perforation 2 ontology of straight pin, the section of mounting hole 2-1
It is square, rectangle or circle.Shown in second cutter hub 3(Fig. 4) it is mounted in mounting hole 2-1, the section of the second cutter hub 3 is positive
Rectangular, rectangle or circle.Cutter head 4 is installed in the front end of second cutter hub 3, and tool bit part is blades of cutting tools, and material is using high
Fast steel W18Cr4V, in order to guarantee that workpiece quality selects reasonable cutting-tool angle, anterior angle 10-15 degree, relief angle 6-8 degree, nose angle 60
Degree, corner radius R1-1.5mm, two sides edge clearance angle 6-8 degree.Add by adjusting 4 extension elongation of cutter head and different measurement methods
The circular arc of work different radii.The material of first cutter hub 1 and the second cutter hub 3 is 45 quenched and tempered steel of Fine Steel Casting iron.
The top of straight pin 2 is machined with axial threaded hole 2-2, the axis of threaded hole 2-2 and the axis weight of straight pin 2
