Milling fixture for curved gears

(manual).
Due to the excessive weight of the round table, the wear of the mating surface of the table and the base is increased. During the cutting process, the cutting fluid and the cutting particles enter the round table, blocking the transmission parts and the worm gear pair, causing the transmission resistance to increase and accelerate. The wear of the transmission member.
Repair, which affects production efficiency.
Weighed the pros and cons, we redesigned the fixture for machining curved gears on a universal milling machine.
After entering the production, it can meet the needs of mass production, successfully solve the problems in the processing of the curved gear, and reduce the structure of the milling fixture of the workers as shown in the figure.
The self-centering chuck connects the crankcase 6 into one, and the crankcase 6 is mounted on 1. flat key 2. split toothed disc 3, 5. bushing 4. T-shaped dowel 6. crankshaft seat 7. mandrel 8. workpiece 9 Pad 10. Base 11.15. Support 12. Milling cutter 13. Pin 14. In the table support 11, the circular table handle is rotated, and the workpiece 8 is rotated together with the crankstock 6 to realize the infeed motion.
The workpiece 8 is positioned and clamped in the mandrel 7, and a T-shaped groove is formed on the middle disc of the core rod 7. The T-shaped screw 4 passes through the crankstock seat 6, and the heart rod can be fastened. The lower end of the mandrel is equipped with a split tooth plate and a screw in the flat key. Under the action of 1, the workpiece axis line rotates coaxially with the mandrel 7, the splitter disk 2, etc., the pin 13 is fixed on the crank seat (A direction), the nut of the T-screw is loosened, and the pin is opened to perform the tooth division. Work, after tightening the nuts of the two T-shaped screws after the teeth, the center line of the tooth width of the tooth working workpiece can be started to be coaxial with the crankshaft axis and the circular table axis. () Book processing processing of spiral parts This book introduces a series of methods for processing slewing parts created by Comrade Zhang Xiaoliang, which is a very practical method for the problem of difficult processing of special guides for mediating parts in production. Book price: 15.60 yuan (including postage), é‚® to the magazine mail order.
