Description
Technical field
With the novel frame for movement that relates to a kind of NC vertical lathe, be specially a kind of numerical control vertical lathe spindle structure.
Background technology
The main axle structure of vertical lathe is divided into two kinds substantially, long main axle structure and short main axle structure.Long main axle structure as shown in Figure 2, main shaft and workbench are integrated with the screw handle, together rotate during work, long main axle structure generally is applied on the following vertical lathe of 4m, because of its main shaft long, two cover double-row conical bearings are installed up and down, and it is effective to feel relieved, so all be that most common vertical lathe all adopts this structure all the time.Another short main axle structure as shown in Figure 3, short main axle structure adopts a cover double-row conical bearing to add a cover thrust ball bearing centering, and main shaft and table base being integrated, only have workbench to rotate with screw in the work, main shaft is motionless, multiplex this structure of numerical control vertical lathe.
If existing numerical control vertical lathe need to reach constant linear velocity turning or cutting thread function, generally all adopt short main axle structure, structure as shown in Figure 3, main shaft and table base being integrated, only have workbench to rotate with screw in the work, main shaft is motionless, on the main shaft top encoder can be installed easily like this, link to each other with the axle that is fixed on bench-top by shaft coupling, workbench and main shaft just produce relative motion in rotary course like this, speed by encoder feedback to digital control system.Yet this structure is because structure adopts a cover double-row conical bearing centering, and the top adopts a cover thrust ball bearing to compress, and locating effect is general, a little less than the axial carrying capacity.
In recent years, along with country supports the new forms of energy construction energetically, the rise of the industries such as wind-powered electricity generation nuclear power has driven prosperity, the especially prosperity of large-sized numerical control vertical lathe in heavy mechanical equipment market.
Because wind-powered electricity generation nuclear power part is mostly relatively more accurate, so general processing all needs numerical control vertical lathe, main shaft all needs to install encoder, accurately control the speed of mainshaft, thereby realize the constant linear velocity cutting, the perhaps function such as cutted thread, for long main shaft vertical lathe, because of its reasons in structure, main shaft and workbench do not have relative motion like this, it is very difficult that the required critical component encoder of digital control system is installed, short main shaft vertical lathe can be installed encoder very easily because main shaft and workbench can produce relative motion, but because this structure is only overlapped double-row conical bearing centering with one, the centering effect is slightly poor, and it is little to bear axial load.
How can install encoder additional at long spindle vertical lathe spindle, to make it can satisfy the numerical control needs, rotating accuracy that again can stable for extended periods of time is a difficulty all the time.

Described main shaft 3 is by upper double row cylindrical roller bearing 19 and 23 centering of lower double row cylindrical roller bearing.
Described shaft coupling 11 is connected the encoder main shaft with connecting axle 10, pass gland 7 with sunk screw 8 gland is linked to each other with connecting axle 10, and then gland 7 is fixed on the end cap 5.
Comprise the 3rd round nut (21) and the 5th round nut (27), can adjust bearing radial gap by the degree of tightness of adjusting the 3rd round nut 21 and the 5th round nut 27, the second round nut 18 and the 4th round nut 22 are fixed bearing inner sleeve.
Also comprise workbench lid 4, establish seal groove, mounting O-shaped rings 17 on the described workbench lid 4.
Described bearing is established bearing inner sleeve, and described bearing inner sleeve is with the 1:12 tapering.
Described penetration pipe 13 is made by seamless steel pipe.
The utility model numerical control vertical lathe spindle structure can keep the high advantage of long main axle structure positioning accuracy, encoder can be installed again realize Digit Control Machine Tool constant linear velocity turning and cutting thread function.Use the present invention to the production of numerical control vertical lathe or that common vertical lathe is changed into numerical control vertical lathe is all significant.
