Abstract
The special follow-rest of a kind of turning slender axles, relate to a kind of lathe process auxiliary tool head, described follow-rest is fixed with a handle on knife rest (1), lathe tool (4) leans against on two pins (3) on steel plate, fixed by two pressing plates (5), two bearings (10) are fastened on two position-adjustable plates (13) with axle (8), locking nut (9), transpose to axle material; Lathe tool (4) arranges on the front left side of support claw or the rear right side is arranged.During turning, total cutting force, the gravity that workpiece itself is downward, makes workpiece be fitted on two bearing claws of follow-rest.Adopt two bearing claws to hold up workpiece, propped up by lathe tool above, workpiece all can not be moved up and down, stable during turning, not easily produce vibration.
Description
Technical field
The utility model relates to a kind of lathe process auxiliary tool head, particularly relates to the special follow-rest of a kind of turning slender axles.
Background technology
Usually axial workpiece Workpiece length and diameter ratio being greater than 25 is called slender axles, such as, feed rod on lathe, leading screw.
Although slender axles profile is also uncomplicated, but because himself rigidity is low, by the impact of the factors such as cutting force, gravity, heat in metal cutting during turning, easy generation vibration and flexural deformation, and produce the defects such as tapering, dolioform and laemodipodiform, be difficult to ensure machining accuracy, make cutting into as the larger processing technology of difficulty of slender axles.
Three key technologies of turning slender axles are: use centre frame and follow-rest to make supplemental support, strengthen the rigidity of workpiece; Solve workpiece thermal deformation and extend problem; The geometry of choose reasonable lathe tool.
With top one folder or two top clamping slender shaft turning.In order to increase the rigidity of workpiece, follow-rest is adopted to do supplemental support.
Follow-rest is mobile with the feeding of lathe tool, offsets back force, and can increase the rigidity of workpiece, Reducing distortion, thus improves the form accuracy of slender axles and reduce surface roughness value.
Summary of the invention
The purpose of this utility model is to provide a kind of turning slender axles special follow-rest, the utility model follow-rest is mobile with the feeding of lathe tool, offsets back force, and can increase the rigidity of workpiece, Reducing distortion, thus improve the form accuracy of slender axles and reduce surface roughness value.
The purpose of this utility model is achieved through the following technical solutions:
The special follow-rest of a kind of turning slender axles, knife rest is fixed with a handle, and lathe tool leans against on two pins on steel plate, and fixed by two pressing plates, two bearing axles, locking nuts are fastened on two position-adjustable plates, transpose to axle material; Lathe tool arranges on the front left side of support claw or the rear right side is arranged.
Advantage of the present utility model and effect are:
1. the utility model follow-rest is mobile with the feeding of lathe tool, offsets back force, and can increase the rigidity of workpiece, Reducing distortion, thus improves the form accuracy of slender axles and reduce surface roughness value.
2., during the utility model turning, total cutting force, the gravity that workpiece itself is downward, makes workpiece be fitted on two bearing claws of follow-rest.Adopt two bearing claws to hold up workpiece, propped up by lathe tool above, workpiece all can not be moved up and down, stable during turning, not easily produce vibration.
Accompanying drawing explanation
Fig. 1 is that the utility model is for forward feeding turning slender axles front view;
Fig. 2 is that the utility model is for forward feeding turning slender axles left view;
Fig. 3 is that the utility model is for floating clamping mechanism and feed reverse cutting slender axles front view;
Fig. 4 is that the utility model is for floating clamping mechanism and feed reverse cutting slender axles left view.
Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is described in further detail.
The utility model provides two kinds of special follow-rest design apparatus.
The follow-rest of two support claws of the first car slender axles shown in Fig. 1, Fig. 2, for forward feeding turning slender axles.In figure, parts are:
1-knife rest 2-bolt 3-sells 4-lathe tool 5-pressing plate 6-bolt 7-slender axles 8-axle
9-locking nut 10-bearing 11-bolt 12-packing ring 13-position-adjustable plate 14-follow-rest body.
The follow-rest of two support claws of the second car slender axles shown in Fig. 3, Fig. 4, for floating clamping mechanism and feed reverse cutting slender axles.In figure, parts are:
1-knife rest 2-bolt 3-sells 4-lathe tool 5-pressing plate 6-bolt 7-slender axles 8-axle
9-locking nut 10-bearing 11-bolt 12-packing ring 13-position-adjustable plate 14-follow-rest body.
From the design principle of two follow-rests above, two bearing claws are only needed to reach requirement.During turning, total cutting force, the gravity that workpiece itself is downward, makes workpiece be fitted on two bearing claws of follow-rest.Adopt two bearing claws to hold up workpiece, propped up by lathe tool above, workpiece all can not be moved up and down, stable during turning, not easily produce vibration.
It is the follow-rest of two support claws of the first car slender axles shown in Fig. 1 and Fig. 2, for forward feeding turning slender axles, lathe tool is on (front) left side of bearing, follow-rest body 14 is made up of steel plate, and a handle is fixed on knife rest 1, and lathe tool 4 leans against on two pins 3 on steel plate, fixed by two pressing plates 5, two bearing 10 axles 8, locking nuts 9 are fastened on two position-adjustable plates 13, and the axle material 7 different to diameter is transposed, and can effectively be supported during the thin axle of turning.
It is the follow-rest of two support claws of the second car slender axles shown in Fig. 3 and Fig. 4, for floating clamping mechanism and feed reverse cutting slender axles, lathe tool is on (afterwards) right side of bearing, follow-rest body 14 is made up of steel plate, and a handle is fixed on knife rest 1, and lathe tool 4 leans against on two pins 3 on steel plate, fixed by two pressing plates 5, two bearing 10 axles 8, locking nuts 9 are fastened on three position-adjustable plates 13, and the axle material 7 different to diameter is transposed, and can effectively be supported during the thin axle of turning.
From the design principle of two follow-rests above, two bearing claws are only needed to reach requirement.During turning, total cutting force, the gravity that workpiece itself is downward, makes workpiece be fitted on two bearing claws of follow-rest.Adopt two bearing claws to hold up workpiece, propped up by lathe tool above, workpiece all can not be moved up and down, stable during turning, not easily produce vibration.
