Abstract
The utility model belongs to mechanical equipment technical field, is related to a kind of hollow long sheath part machine tooling holding device.It includes the top of locating shaft and circular cone structure, and loaded on that can rotate in a circumferential direction on locating shaft and on locating shaft, the locating shaft is fixedly installed on tailstock tool the center sleeve.The utility model cooperates machine tool chief axis fix top to longer hollow long sheath part, guarantees the stability of cutting process and the machining accuracy of part.
Description
Technical field
The utility model belongs to mechanical equipment technical field, is related to a kind of hollow long sheath part machine tooling with holding out against dress
It sets.
Background technique
In machine industry, Excircle machining is carried out to shorter hollow long sheath part, part can be blocked with spindle chuck
One end, other end cantilever complete processing；When being processed for longer hollow long sheath part, the fixed other end of one end
Cantilever, it is unreliable that when cutting, positions, and design requirement is not achieved in machining accuracy.
Utility model content
The purpose of this utility model is in view of the problems of the existing technology to provide a kind of hollow long sheath part lathe to add
Work holding device.
The specific technical solution of the utility model is as follows:
A kind of hollow long sheath part machine tooling holding device, top, the institute including locating shaft and circular cone structure
It states center sleeve to be loaded on locating shaft and can rotate in a circumferential direction on locating shaft, the locating shaft is fixedly installed on tailstock tool；
Further, the top coning angle is 55-80 °；
Further, the locating shaft includes suit shaft part and fixed shaft part, described top to be installed on the suit shaft part
On, the fixed shaft part is plugged on the tailstock tool；
Further, fixing screws are provided on the suit shaft part；
Further, ejection nut is installed on the fixed shaft part.
The utility model has the following beneficial effects:
The utility model cooperates machine tool chief axis fix top to longer hollow long sheath part, guarantees cutting process
Stability and part machining accuracy；The top of the utility model uses circular cone structure, while guaranteeing to hold out against secured,
The top hollow long sheath part that can be applicable in different-diameter.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
A kind of hollow long sheath part machine tooling holding device as shown in Figure 1, including locating shaft 1 and frustum of a cone knot
Top the 2 of structure, described top 2 are set on locating shaft 1 and can rotate in a circumferential direction on locating shaft 1, the fixed peace of the locating shaft 1
Loaded on tailstock tool 3, top 2 coning angle is 55-80 °；The locating shaft 1 includes suit shaft part 1-1 and fixing axle
Section 1-2, described top 2 are installed on the suit shaft part 1-1, and the fixed shaft part 1-2 is plugged on the tailstock tool 3,
It is provided with fixing screws 4 on the suit shaft part 1-1, ejection nut 5 is installed on the fixed shaft part 1-2.
The detailed process that hollow long sheath part 6 is held out against using the utility model are as follows:
The locating shaft 1 of the utility model is plugged on the tailstock tool 3, is fixed on locating shaft 1 by fixing screws 4
On the end face of tailstock tool 3, hollow 6 one end of long sheath part is by main shaft claw clamping, and the other end is held out against by top 2, main shaft band
The hollow rotation of long sheath part 6 is moved to be processed；Since top 2 using circular cone structure, top 2 circular cone inclined-plane and hollow length
The internal diameter of cover parts 6 is in close contact, so that top 2 can be applicable in the hollow of different-diameter while guaranteeing to hold out against secured
Long sheath part 6 will remove when removing to the utility model on end face of the fixing screws 4 by tailstock tool 3, eject in rotation
Nut 5 ejects locating shaft 1 by tailstock tool 3.
