Abstract
The utility model discloses a follower rest which comprises a main body, a sleeve, a screw, clamp rings, bearings and shaft sleeves, wherein, the sleeve is positioned inside the left end of the main body and connected with the main body through the screw; the bearings are installed in the inner holes at the right end of the U-shaped groove of the main body; the clamp rings are used for fixing the bearings; and the shaft sleeves are sleeved in the inner rings of the bearings. In the utility model, the deformation and vibration of the slender axle-liked parts in the manufacturing process are effectively avoided, the machining precision of the parts is improved, and the defect of a traditional processing method is overcome. Therefore, the follower rest has the advantages of simple structure, low cost, and wide application range.
Description
Technical field
The utility model belongs to field of machining, relates to a kind of follow-rest.
Background technology
In the process of thin and long shafts workpiece such as processing long spiro nail, screw thread plug; Following problem appears in Shi Changhui: 1, the poor rigidity of slender axles; Be easy to occur bending and deformation, produce vibration, thereby influence machining accuracy and surface roughness because of the effect of cutting force and gravity; 2, the thermal diffusion performance of slender axles is poor, under the effect of heat in metal cutting, can produce sizable line and expand, if the two ends of axle are fixed bearing, then workpiece can be because of the elongation bending.Therefore in actual process, need a kind of thin and long shafts workpiece that can effectively prevent badly and produce the follow-rest of distortion, vibration, thereby improve the machining accuracy of workpiece.
The utility model content
The technical problem that the utility model solves:, provide a kind of thin and long shafts workpiece that can prevent the follow-rest of distortion and vibration in process, to occur in order to overcome the defective that traditional diamond-making technique exists.
The technical scheme of the utility model:
As shown in fig. 1, a kind of follow-rest of the utility model mainly is made up of parts such as main body, sleeve, screw, collar, bearing, axle sleeves.It is inner that sleeve is positioned at the main body left end, is connected with main body through screw, and the endoporus of main body U type groove right-hand member is equipped with bearing, and collar is motionless with bearing fixing, and axle sleeve is placed on the bearing inner race.The utility model with can in U type groove, carry out turning after knife rest cooperates clamping to bar, thereby can process thin and long shafts products such as the long spiro nail that meets the demands, screw thread plug.
In process, adopt the technical scheme of the utility model can prevent that distortion from appearring in slender axles, increase the rigidity of slender axles, make the machining slender shaft precision be improved; The utility model processing cost is low, when the different bars of processing footpath, only need exchange sleeve for and axle sleeve gets final product, and does not need whole exchanging for; The utility model applicability is strong, is adapted to multiple lathe, and is applied widely.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure 1, main body, 2, sleeve, 3, screw, 4, collar, 5, bearing, 6, axle sleeve
The specific embodiment
The embodiment of the utility model: the long spiro nail to utilize bar processing φ D is an example, describes in conjunction with accompanying drawing 1.
Be connected with main body 1 through screw 3 sleeve 2, sleeve 2 right-hand members have a through hole, and the diameter of this through hole is φ D+0.15mm, and the endoporus of main body 1U type groove right-hand member is equipped with bearing 5, and is fixed with collar 4, is inserted in axle sleeve 6 on bearing 5 inner rings.
Advance the bar clamping in the chuck of lathe; The utility model and knife rest can carry out turning processing to bar after cooperating clamping in U type groove; Along with turning process constantly carries out, the φ D part that has processed will get into the through hole of sleeve 2 right-hand members, and through hole will reduce the deflection and the vibration of workpiece; In addition, when turning, under the drive of lathe spindle, axle sleeve along with bar rotates, plays the effect of intermediate conveyor and supporting workpiece with bearing, thereby has further reduced the whipping of workpiece in process, has improved the machining accuracy of workpiece.
