The adjustable follower rest comprises a bracket, a C-shaped rack and three support parts, wherein, the C-shaped rack is fixed on the bracket; the support parts used for supporting slender shaft workpieces to be processed are arranged on the inner side of the C-shaped rack through corresponding screw driving mechanisms respectively; the support parts and the screw driving mechanisms are in one-one correspondence and fixed with each other; each support part comprises a wheel carrier and a roller; the roller is erected on the wheel carrier; and the wheel carrier is fixed with a corresponding screw driving mechanism. The utility model has the advantages that the structure is compact; the use process is in accordance with that of an old-type follower rest; the larger the length-diameter multiple proportion is, the higher the superiority of the utility model is; the dimensional precision of parts processed by using the adjustable follower rest is high; lower surface roughness value can be realized easily; the processing range is wide; the processing efficiency is high; and the processing cost is greatly reduced.
Description
Technical field
The utility model relates to the cutting auxiliary mould of lathe, specifically be a kind ofly be applicable to that lathe turning processing φ 8mm is above, the L/D ratio value is greater than the adjustable follow-rest of roller three-jaw of 20: 1 above thin and long shafts parts.
Background technology
On lathe during the turning slender axles because the slender axles poor rigidity, yielding in process, vibration so that workpiece size is difficult for guaranteeing, therefore, on lathe, need to install as: auxiliary moulds such as follow-rest, centre frame are processed.Existing lathe makes cylinder iron pawl support part with follow-rest, and produces sliding friction between cast iron pawl head and part, and frictional heating is big, and the cast iron pawl is easy to wear, in process workpiece is produced big frictional force, directly influences the workpiece rigidity; During use, the sufficient lubricating oil of must annotating reduces frictional heating, thereby causes working (machining) efficiency lower to reduce friction, and processing cost is higher.
Summary of the invention
The utility model is big, easy to wear for cast iron pawl and the friction between workpiece that solves existing follow-rest application, and the problems such as lubricating oil use of must annotating provide a kind of roller three-jaw adjustable follow-rest.
The utility model is to adopt following technical scheme to realize: the adjustable follow-rest of roller three-jaw, comprise support, be fixed in C shape frame on the support, three be arranged at the support member that C shape frame inboard is used to support slender axles workpiece to be processed by corresponding screw-drive mechanism respectively, support member and screw-drive mechanism are one-to-one relationship, support member and screw-drive mechanism are fixed, described support member comprises wheel carrier, is set up in the roller on the wheel carrier, and wheel carrier and corresponding screw-drive mechanism are fixed; And the roller turning cylinder that direction is set is identical with slender axles workpiece placement direction to be processed.
Described support comprises backing plate, passes through the bearing of bolt vertical fixing on backing plate, and bearing is fixed by bolt and C shape frame one side, offers the strip through hole that can realize that the bearing installation site is adjusted on the backing plate, and bolt passes the strip through hole hold-down support on the backing plate.
C shape frame opposite side has C shape baffle plate by bolting, and C shape is placed between bearing and the C shape baffle plate, and the width of C shape frame is less than the width of C shape baffle plate, is fixed with the buting iron that is positioned at the one-sided or both sides of support member wheel carrier on the C shape baffle plate.
The free end of the adjusting leading screw of described screw-drive mechanism is fixed with rocking bar or handwheel.
Compared with prior art, the utility model is used roller and is helped workpiece, substitute the cast iron pawl with roller, promptly substituted sliding friction between cast iron pawl and workpiece with the rolling friction between roller and workpiece, rolling frictional resistance between roller and the workpiece is much smaller than the sliding-frictional resistance between cast iron pawl and the workpiece, greatly reduce the generation of frictional heat, the lubricating fluid of need not annotating; And can in turning process, certain roll extrusion effect be arranged to surface of the work, improved the surface roughness of workpiece to a certain extent.Use 1: 70 times of slender axles of the auxiliary turning processing of follow-rest described in the utility model, the turning process is steady, and cutting speed can improve 2～3 times, and the slender axles linearity that processes guarantees within 0.05mm.C shape baffle plate and buting iron fixing on the C shape frame can effectively limit and bear radial load and the axial force of wheel carrier in turning process.In addition, support adopts the steel part split production, is made of backing plate and bearing with bolting, makes bearing can realize upper and lower and front and back are regulated, and need mix up centre distance like this on the different model lathe, can use after fastening, conveniently, flexible.
The utility model compact conformation, use is consistent with old-fashioned follow-rest, and the handled easily person adapts to, regulates, and the major diameter multiple proportions is big more to embody superiority of the present utility model more; The parts size precision height that uses the utility model to process is realized easily than the low surface roughness value; The range of work is wide, can be used for thick, the fine finishining of all kinds of slender axles, elongated leading screw; The working (machining) efficiency height cuts down finished cost greatly, is worth promotion and application widely.
