The utility model has simple structure, convenient use, high universality and low cost, the first positioning bolt, the second positioning bolt and the third positioning bolt of the follow rest are respectively contacted with the upper side, the lower side and the side of the slender shaft workpiece, the contact points are more and the stress is uniform, and the quality problems of overlarge deformation, serious tool vibration and the like of the slender shaft workpiece caused by cutting can be effectively eliminated.
Description
Technical Field
The utility model relates to the technical field of mechanical tools, in particular to a follow rest used when a slender shaft is turned.
Background
When the ratio of the length to the diameter of the workpiece is more than 25 times, the workpiece is called slender shaft. The slender shaft has poor rigidity, and the phenomena of thermal deformation, stress bending and the like are easy to occur in the cutting process of a lathe, so that when the slender shaft is turned, a follower rest is required to be used for reducing the error and the deformation of a workpiece.
The follow rest is one of the center rest, but the center rest can not move together with the lathe tool along with the lathe tool carriage, and is relatively fixed, and the follow rest can move flexibly along with the lathe tool carriage and the lathe tool. The follower rest is an auxiliary device for radially supporting a rotating workpiece. During machining, the workpiece moves together with the tool in the axial direction of the workpiece.
The main function of the follow rest is to strengthen the cutting stability of the slender shaft workpiece, and can stably support the excircle of the workpiece in the cutting process to prevent the workpiece from shaking. However, the existing follow-up rest has the problems of large volume, troublesome installation, high cost, large deformation of slender shaft parts caused by the cutting force of a tool nose during processing and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provides a follower rest used for turning a slender shaft.
In order to achieve the purpose, the technical scheme of the utility model is as follows: the utility model provides a follower rest that uses when turning slender axles which characterized in that: including the frame body, the frame body is including parallel last backup pad and bottom suspension fagging, a side end of going up backup pad and bottom suspension fagging passes through the riser and connects, the bottom suspension fagging is longer than last backup pad, go up the first positioning bolt of threaded connection in the backup pad, threaded connection second positioning bolt in the bottom suspension fagging, riser threaded connection third positioning bolt, first positioning bolt, second positioning bolt, third positioning bolt's bolt tail all is inside towards the frame body, no nodical point between second positioning bolt central line, first positioning bolt central line and the third positioning bolt central line.
Further, the method comprises the following steps of; the first positioning bolt is vertically connected with the upper supporting plate, the second positioning bolt is vertically connected with the lower supporting plate, the third positioning bolt is vertically connected with the vertical plate, and the center line of the first positioning bolt, the center line of the second positioning bolt and the center line of the third positioning bolt can point to different points of the same horizontal straight line.
The utility model has the beneficial effects that: the utility model has simple structure, convenient use, high universality and low cost, the first positioning bolt, the second positioning bolt and the third positioning bolt of the follow rest are respectively contacted with the upper side, the lower side and the side of the slender shaft workpiece, the contact points are more and the stress is uniform, and the quality problems of overlarge deformation, serious tool vibration and the like of the slender shaft workpiece caused by cutting can be effectively eliminated.

Detailed Description
Example (b):
as shown in fig. 1 to 4, a follow rest that uses during turning slender axles, including the frame body, the frame body is including parallel last backup pad 1 and bottom suspension fagging 2, a side end of going up backup pad 1 and bottom suspension fagging 2 is connected through riser 3, bottom suspension fagging 2 is longer than last backup pad 1, go up first positioning bolt 4 of perpendicular threaded connection on the backup pad 1, perpendicular threaded connection second positioning bolt 5 on the bottom suspension fagging 2, 3 perpendicular threaded connection third positioning bolts 6 of riser, the bolt tail of first positioning bolt 4, second positioning bolt 5, third positioning bolt 6 all is inside towards the frame body, the directional difference of same horizontal straight line of first positioning bolt central line, second positioning bolt central line, third positioning bolt central line.
During the use, put the frame body on 7 sword positions of knife rest, on 7 sword position planes of knife rest are pasted tightly to lower backup pad 2, then place lathe tool 8 on lower backup pad 2, then fasten bolt fastening with knife rest 7 and live lower backup pad 2, tighten up, then move knife rest 7 to slender axles work piece 9 suitable position, screw up first positioning bolt 4, second positioning bolt 5, third positioning bolt 6 to slender axles work piece 9 arc surface and screw up, then begin the turning.
The above-described embodiments are merely preferred embodiments of the present invention, which is not intended to be limiting in any way, and other variations and modifications are possible without departing from the scope of the utility model as set forth in the appended claims.
In the description of the present invention, it is to be understood that the terms indicating an orientation or positional relationship are based on the orientation or positional relationship shown in the drawings only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
