Abstract
The utility model discloses a positioning structure for a power head main shaft and a shell of a tapping machine. The positioning structure comprises the main shaft and the shell; each of the middle part of the main shaft and the head of the main shaft is movably connected with the shell through a movable positioning device; and each movable positioning device comprises a deep groove ball bearing and a thrust ball bearing arranged in parallel. Through the positioning structure, the axial stress of the main shaft can be effectively promoted, the tapping pitch quality is ensured, the service life of the tapping machine is greatly prolonged at the same time, and great convenience is brought to maintenance of equipment.
Description
Technical field
The utility model relates to a kind of tapping machine unit head, particularly the position structure of a kind of tapping machine dynamic head main spindle and housing.
Background technique
For guaranteeing the effective rotation at work of tapping machine dynamic head main spindle, existing main shaft 1 ' housing 2 ' on position structure as shown in Figure 1, main shaft 1 ' middle part by a deep groove ball bearing 31 ' with housing 2 ' flexible connection, main shaft 1 ' head by two deep groove ball bearings that are set up in parallel 32 ', 33 ' with housing 2 ' flexible connection.At this, because of deep groove ball bearing 31 ', 32 ', 22 ' performance possess certain ability of bearing bi-directional axial load and radial load, but its thrust load that can bear is very limited, the force request that can't adapt to the axial large impact power of main shaft 1 in the actual processing ' be subject to, and then had a strong impact on working life of tapping pitch quality and tapping machine unit head, and brought very burden for the maintenance of tapping machine unit head.
The model utility content
For the problems referred to above, the utility model has designed the position structure of a kind of tapping machine dynamic head main spindle and housing, it is the axially loaded of lifting spindle effectively, can greatly prolong the working life of tapping machine when guaranteeing tapping pitch quality, and the maintenance of the equipment of giving brings great convenience.
For achieving the above object, the utility model is by the following technical solutions:
The position structure of a kind of tapping machine dynamic head main spindle and housing, comprise main shaft and housing, it is characterized in that: described main shaft middle part and head all are flexibly connected by a movable locating device and housing, and each movable locating device includes and is deep groove ball bearing and the thrust ball bearing that is set up in parallel.
Further, seat ring and the housing of above-mentioned deep groove ball bearing are equipped with, and the blowout patche of deep groove ball bearing and main shaft drive fit arrange.
Further, the seat ring external diameter of above-mentioned thrust ball bearing and housing drive fit arrange, and the seat ring internal diameter of thrust ball bearing cooperates with gap of main reinforcement, and the blowout patche external diameter of thrust ball bearing cooperates with body clearance, and the blowout patche internal diameter of thrust ball bearing and main shaft drive fit arrange.
Further, the blowout patche of above-mentioned thrust ball bearing is towards the deep groove ball bearing setting, and is provided with spacing washer between the blowout patche of the blowout patche of thrust ball bearing and deep groove ball bearing.
Each movable locating device of the utility model all comprises a deep groove ball bearing and a thrust ball bearing, and deep groove ball bearing possesses good radial capacity and certain bi-directional axial load-carrying ability, and thrust ball bearing possesses good thrust load ability, being equipped with side by side of this deep groove ball bearing and thrust ball bearing, can guaranteeing to possess good thrust load ability to bear when the relative housing of main shaft is flexibly connected, can satisfy the large axial directional load requirement that main shaft bears in the actual processing.
