Description

Technical Field

[0001] This utility model relates to the field of gear processing equipment technology, and more specifically, to a gear chamfering processing device. Background Technology

[0002] A gear chamfering machine is a machine tool that chamfers and rounds the ends of gear teeth. This machine tool is generally semi-automatic and allows for unequal feed rates on the worktable. It is an indispensable processing equipment in the production of gearboxes and other gear shifting mechanisms. During the chamfering process, upper and lower cutters cut to form two chamfered surfaces on the workpiece. Burrs will remain at the ridge line formed by the intersection of the two chamfered surfaces. The size of the burrs is closely related to the workpiece material and the wear of the tools, and these burrs need to be removed before assembly.

[0003] During gear processing, the gears need to be fixed first. This process is usually done manually, which is time-consuming. Also, the distance between the fixtures is fixed, which cannot accommodate gears of various thicknesses, resulting in a narrow processing range and hindering the improvement of gear processing efficiency.

On one side; the second motor 7 is connected to a rotating shaft 10 on the side near the fixed plate 9, and a drive gear 11 is connected to the end of the rotating shaft 10 away from the second motor 7. A pressure plate 14 is provided on the side of the fixed plate 9 near the movable seat 8. Several guide rods 12 are slidably connected to the fixed plate 9, and the ends of the guide rods 12 near the movable seat 8 are all connected to the pressure plate 14. A transmission rod 18 is arranged horizontally inside the movable seat 8, and a gear body 16 is installed on the transmission rod 18. A through hole 15 is opened horizontally on the fixed plate 9, and the end of the transmission rod 18 away from the movable seat 8 corresponds to the through hole 15.

[0018] The base 1 has a sliding groove, the lead screw 3 is disposed inside the sliding groove, and the end of the movable seat 8 near the base 1 is in contact with the inner wall of the sliding groove; this facilitates the lead screw 3 to drive the movable seat 8 to move horizontally on the base 1.

[0019] The guide rod 12 is fitted with an elastic component 13 at the end away from the movable seat 8. The two ends of the elastic component 13 are respectively connected to the fixed plate and the end of the guide rod 12. The pressure plate 14 is a ring structure, which facilitates the limiting of the gear body 16.

[0020] The transmission rod 18 has gear teeth and a limiting member 19 on one side wall near the fixed plate 9. The limiting member 19 engages with the gear. The radius of the through hole 15 is larger than the radius of the transmission rod 18, so that the transmission rod 18 can drive the gear body 16 to rotate.
