Abstract
An elongated shaft automatic-feeding follow rest comprises a support, a chuck base, a spring chuck, an adjusting nut, a cylinder and a rotation resisting pin. The follow rest is arranged on a carriage of a machine tool through the support; the chuck base is fixed on the support and internally provided with the spring chuck; the tail end of the spring chuck is provided with the adjusting nut; the chuck base is connected with the cylinder; an ejector rod extends into the spring chuck; and the rotation resisting pin is arranged between the spring chuck and the chuck base. As the follow rest is arranged on the carriage of the machine tool, therefore the follow rest moves together with the carriage. The distance between a cutter and the follow rest is fixed and the rigidity is kept the same in cutting. The spring chuck serves as closed type fixed bearing and shares one centre line together with a main shaft clamp sleeve; two freedom degrees of the elongated shaft are limited in radial direction; and the elongated shaft automatic-feeding follow rest is safe and reliable to use, suitable for high-speed processing and compact and simple in structure.
Description
Technical field
The utility model relates to the slender axles processing unit (plant) of lathe, and particularly a kind of lathe that can make is realized self-feeding processing, automatic centering, can also be adjusted the follow-rest that supports the gap.
Background technology
At present, traditional follow-rest (two pawls or three-jaw) is semi-enclosed structure, manually adjusts the pawl pin respectively, and the cylindrical that pushes up workpiece play supporting role.For slender axles, be subjected to bigger top power easily and be out of shape even crooked, the power too little rigidity deficiency that causes easily in top causes workpiece accuracy, surface roughness not to reach requirement.Follow-rest weares and teares easily, and the adjustment center is difficulty relatively.Such processing method, the precision of product is low, the scrappage height, production cost is high.Traditional follow-rest does not have automatic feeding yet, and production efficiency is not high.
Summary of the invention
The purpose of this utility model is: a kind of slender axles self-feeding follow-rest of adjusting supported clearance size, automatic centering and automatic feeding function is provided.
For achieving the above object, the utility model is achieved through the following technical solutions.
A kind of slender axles self-feeding follow-rest, comprise: support, base of the carrier head, collet, adjusting nut, cylinder, anti-rotation pin, it is characterized in that: follow-rest is installed on the saddle of lathe by support, base of the carrier head is fixed on the support, the inner mounting spring chuck of base of the carrier head, the collet tail end has adjusting nut; Connecting cylinder on the base of the carrier head, push rod reaches in the collet; The anti-rotation pin is installed between collet and the base of the carrier head.
Advantage of the present utility model is: because follow-rest is installed in by support on the saddle of lathe, move with big palette.The lateral separation of cutter and follow-rest is fixed, and rigidity remains unchanged in the time of cutting.Collet is as enclosed fixed bearing, and is safe and reliable radially limiting two frees degree of slender axles with the same center line of main shaft chuck, suitable High-speed machining.The collet aperture is adjusted to suitable size with slender axles, and leaving an amount of gap does not influence the slender axles rotation.When adjusting the collet pore size, its center can not change.Slender axles run through main frame and follow-rest, and cylinder holds out against slender axles, and saddle drive slender axles make it stretch out main frame and finish self-feeding.Automatic feeding of this programme and follow-rest be one each other, and compact conformation is simple, is the desirable processing unit (plant) of machined into slender axles.Slender axles self-feeding follow-rest of the present utility model can improve the precision and the speed of product processing.
In the utility model, described collet endoporus studs with carbide alloy.It can improve service life.
In the utility model, described collet tail end is equipped with fairlead.It can provide additional support, and is beneficial to the clamping feeding.
In the utility model, between described collet and the base of the carrier head screw or key.It can replace the anti-rotation pin, prevents that collet from rotating.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the cross-sectional view of the utility model follow-rest.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
In conjunction with Fig. 1, shown in Figure 2, the slender axles self-feeding follow-rest of present embodiment, mainly comprise support 1, base of the carrier head 5, collet 4, adjusting nut 9, cylinder 7, anti-rotation pin 2 etc., it is characterized in that: integral body is installed on the saddle 15 of main frame 12 by support 1, base of the carrier head 5 is fixed on the support 1 by holding screw 6, inner mounting spring chuck 4, collet 4 tail ends have adjusting nut 9; Connecting cylinder 7 on the base of the carrier head 5, push rod 8 reaches in the collet 4; Anti-rotation pin 2, replacements such as the also available key of anti-rotation pin 2, screw are installed between collet 4 and the base of the carrier head 5.Collet 4 endoporus stud with carbide alloy 3, to improve service life; Collet 4 tail ends are equipped with fairlead 10, and additional support is provided, and are beneficial to the clamping feeding.
At first, the utility model is installed on the saddle 15 of main frame 12 by support 1, adjusts the center.Slender axles 11 pass main frame chuck 13, pass collet 4.Rotation adjusting nut 9 is adjusted the pore size of collet 4, and leaving an amount of gap does not influence slender axles 11 rotations.During adjustment, because the effect of anti-rotation pin 2, collet 4 does not change and can only move axially, and under the taper hole effect of base of the carrier head 5, the aperture of collet 4 changes simultaneously, but its center is constant.When collet 4 wearing and tearing, can make things convenient for again and regulate its pore size.
Then, cylinder 7 descending push rods 8 hold out against slender axles 11, and main frame chuck 13 unclamps slender axles 11, and big palette 15 drives slender axles 11 and moves together, stops feeding after putting in place; Main frame chuck 13 clamping work pieces, the cylinder 7 up slender axles 11 that unclamp have so just been finished the self-feeding process.Start main frame 12, feeding cutter 14 has been realized automation processing.
