Description

Rigid follow-up chamfering assembly

Technical Field

The utility model belongs to the technical field of the machine tooling, concretely relates to rigidity follow-up chamfer assembly.

Background

The gear chamfering is an important measure for chamfering the circular tooth profile on the end face of the gear and preventing the tooth surface from being raised due to small collision or burrs to generate noise and damage the meshing tooth surface.

Different chamfering machines adopt different chamfering clamps or assemblies, the existing chamfering clamp does not have a thrust ball bearing, an inner hole adopts a copper transition sleeve, the shaft and flange are manually injected with oil before processing, the friction force is large, the service life is short, and the use is inconvenient.

Disclosure of Invention

An object of the utility model is to provide a rigidity follow-up chamfer assembly to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a rigid follow-up chamfering assembly comprises a first chamfering blade, a second chamfering blade, a flange and a mandrel, wherein a needle bearing and thrust ball bearings are mounted on the mandrel, the two thrust ball bearings are located at two ends of the needle bearing, the flange is mounted outside the needle bearing, the needle bearing is arranged in a flange hole, the flange is provided with the first chamfering blade and the second chamfering blade, an end cover is mounted at the position of the thrust ball bearing close to the connecting end of the mandrel and a machine tool, and the thrust ball bearing is locked through a gasket and a locking nut.

The utility model discloses a further improvement lies in: waist grooves are formed in the first chamfering blade and the second chamfering blade.

The utility model discloses a further improvement lies in: and the gland of the end cover presses the lower edges of the thrust ball bearing and the flange.

The utility model discloses a technological effect and advantage:

1. the middle main shaft plays a role in being connected with a machine tool and also plays a role of an inner ring of the needle bearing piece, so that the structure is more compact;

2. the chamfering cutter is assembled through the flange and plays a role of an outer ring of the needle bearing, and the flange, the middle main shaft and the needle shaft form a bearing structure;

3. the thrust ball bearing resists the lateral force of the chamfer, and meanwhile, the rotation resistance is reduced;

4. by using the needle roller bearing, the rotating friction force is small while the centering and the positioning are carried out, and the follow-up is smoother;

5. the chamfering blade is provided with a waist groove structure to adapt to the matching of different gear thicknesses and helical angles.

6. The mechanism rotates smoothly without resistance, so that chamfering precision is high, batch chamfering consistency is good, machining precision of workpieces is improved, and equipment runs stably.
