Description
Technical field
The present invention relates to vertical lathe, a kind of grinding attachment of vertical lathe particularly, this grinding attachment makes vertical lathe can not only realize the process operation of turning, also can realize the process operation of grinding.
Background technology
Vertical lathe is that a kind of main shaft arranges that vertically workbench rotates in horizontal plane, and knife rest is made the lathe of vertical or oblique feeding, is used for the bigger disk-like accessory of crudy.This lathe is made up of base, workbench, column, crossbeam, traveller, knife rest usually, and wherein, traveller is connected on the crossbeam and vertical the layout; Knife rest is located at the lower end of traveller; Knife rest can move along X-direction and Z-direction, and main shaft is coaxial with the Z axle, and motor rotates around main shaft through transmission mechanism drive workbench during work; And the relative workpiece of knife rest is done cutting movement, thereby realizes the turning machining functions.But because the knife rest in the present vertical lathe can only move along X-direction and Z-direction, can not rotate,, and can't carry out grinding some precision and the demanding workpiece of surface smoothness so present existing vertical lathe can only be accomplished turning processing.For this reason, on the basis of existing vertical lathe turning processing, function how to develop grinding is the problem that the present invention studies.
Summary of the invention
The present invention provides a kind of vertical lathe grinding attachment, is intended to the function of exploitation grinding on the basis of original vertical lathe turning processing, thereby realizes the purpose of a tractor serves several purposes.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of vertical lathe grinding attachment; It is characterized in that: the traveller of on vertical lathe, vertically arranging is a hollow structure, and a rotating shaft vertically is set in the chamber of traveller hollow structure, passes through the bearing rotating support between this rotating shaft and the traveller; The upper end of rotating shaft is provided with a servomotor, and this servomotor and rotating shaft are in transmission connection;
Said rotating shaft also is a hollow structure; Inner top fixedly installs a straight line driving mechanism in the chamber of rotating shaft hollow structure; A drive rod is stretched out in the straight line driving mechanism lower end, and the drive rod lower end is connected with a grasp device, this grasp device by one promptly head be movably connected on the head promptly at least two promptly pawl constitute; Respectively promptly pawl is evenly arranged at horizontal circumferencial direction; Corresponding promptly pawl is established a circle projection in the Nell wall of the chamber of rotating shaft hollow structure, this projection drives at head promptly and forces promptly under the state that promptly pawl moves down that pawl opens, and drives at head promptly to force promptly pawl promptly under the state that promptly pawl moves up;
The chamber inner bottom part of rotating shaft hollow structure is provided with big end inner conical surface down, and a knife rest is arranged, and this knife rest is provided with the inserting handle that usefulness is installed; The front end of inserting handle is provided with Latin; This Latin is made up of shaft shoulder structure, and Latin matches with pawl promptly and constitutes the tension structure, and the handle body of inserting handle is provided with male cone (strobilus masculinus); This male cone (strobilus masculinus) cooperates the formation location structure with said inner conical surface, knife rest is equipped with the emery wheel that grinding is used bottom.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the lower end of said rotating shaft is provided with locating slot, and position that should locating slot is provided with drive block on knife rest, and drive block embeds in the locating slot and cooperates under the knife rest installment state.
2, in the such scheme; Said promptly head is made up of first shaft shoulder and second shaft shoulder that are located on the axis body; First shaft shoulder is positioned at axis body top; Second shaft shoulder is positioned at the axis body bottom, is formed with a recess between first shaft shoulder and second shaft shoulder, in the recess that promptly the first half of pawl forms between first shaft shoulder and second shaft shoulder.
3, in the such scheme, said each the first half outside of firmly grasping pawl is provided with protuberance, and projection position set on this protuberance and the rotating shaft inwall is corresponding.
Operation principle of the present invention is: when realizing that turning adds man-hour; Need not use grinding attachment; The knife rest that lathe tool is housed is installed on the rotating shaft, carries out turning and add the man-hour rotating shaft and do not rotate, on X-direction and Z-direction, move with the location by traveller driven rotary axle; Workbench drives the workpiece rotation, and lathe tool is cut processing in the enterprising driving of workpiece of rotation; When realizing grinding; Need use grinding attachment, the knife rest that emery wheel is housed is installed on the rotating shaft, traveller driven rotary axle moves on X-direction and Z-direction and positions; Workbench drives the workpiece rotation; The rotation of servomotor driven rotary axle, thus drive emery wheel and workpiece reverse rotation, through emery wheel and the relative motion of workpiece under certain pressure finished surface is carried out finished machined.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
1, because the present invention has increased a rotating shaft on the basis of existing vertical lathe, makes vertical lathe can not only realize the function of turning, also can realize the function of grinding.
2, because the present invention has the drive block that is complementary with rotating shaft lower end locating slot on knife rest, reduce the frictional force of knife rest and rotating shaft inwall greatly, increased the service life of knife rest.
