Abstract

The utility model provides a kind of pneumatic support formula damping follow-rest, and problem to be solved is: bracing frame and support claw become from being rigidly connected and flexibly connect.Main points of the present utility model are: it comprises bracing frame, support claw and cylinder; Bracing frame base plate there is rod aperture, the diameter of rod aperture is between diameter of piston rod and cylinder diameter of cylinder, cylinder piston rod from bracing frame base plate pass beneath rod aperture after, the base board flange dish of cylinder upper end face is fixed on below bracing frame base plate, and the support claw ring flange of piston rod end is fixed on below support claw.Good effect of the present utility model is: pneumatic follow-rest damping, has both achieved balance workpiece cutting force, eliminates workpiece deformation vibrations, meanwhile, flexible damping, avoid workpiece cutting force abnormal time damage to main frame cutter.

Description

Pneumatic support formula damping follow-rest
Technical field
The follow-rest that the utility model uses when relating to oblique lathe bed Digit Control Machine Tool processing thin and long shafts part is pneumatic support formula damping follow-rest specifically.
Background technology
In Digit Control Machine Tool processing thin and long shafts part process, because workpiece slender axles span is too large, easily produce distortion and vibration, need to use follow-rest to support workpiece in process, eliminate the distortion because workpiece stiffness deficiency causes, vibration.Current follow-rest is, the base plate of support claw, column and bracing frame is rigidly connected successively.Thin and long shafts part is placed on above support claw, supports thin and long shafts part, and bracing frame is arranged on oblique lathe bed lathe saddle.Be rigidly connected because support claw and bracing frame belong to, follow-rest is mobile with the feeding of lathe tool, and rigidity offsets lathe tool back force.When machine cut power is extremely excessive, because of without buffer gear, easily damage is caused to machine tool.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of pneumatic support formula damping follow-rest.
The purpose of this utility model is achieved in that it comprises bracing frame and support claw, it is characterized in that: further comprising cylinder; Bracing frame base plate there is rod aperture, the diameter of rod aperture is between diameter of piston rod and cylinder diameter of cylinder, cylinder piston rod from bracing frame base plate pass beneath rod aperture after, the base board flange dish of cylinder upper end face is fixed on below bracing frame base plate, and the support claw ring flange of piston rod end is fixed on below support claw.
Be arranged on by bracing frame on oblique lathe bed lathe saddle, thin and long shafts part is placed on above support claw.Operation process is, when cylinder piston rod stretches out, ejection support claw, by cylinder supports workpiece.Because cylinder gas pressure is adjustable, can according to workpiece concrete actual demand setting support force size; Again because pneumatic support is flexible support, not only eliminate workpiece deformation, vibrations, and when workpiece cutting back force is extremely excessive, workpiece has to produce deforming displacement, and supporting cylinder piston rod can return, thus protection machine tool is not damaged.
Compared with prior art, good effect of the present utility model is: pneumatic follow-rest damping, has both achieved balance workpiece cutting force, eliminates workpiece deformation vibrations, meanwhile, flexible damping, avoid workpiece cutting force abnormal time damage to main frame cutter.
Accompanying drawing explanation
The utility model is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram that the utility model is arranged on oblique lathe bed lathe saddle.
Detailed description of the invention
See Fig. 1, it comprises bracing frame 2 and support claw 1, it also comprises cylinder 4, bracing frame base plate 21 has rod aperture, the diameter of rod aperture between piston rod 42 diameter and cylinder block 41 diameter, cylinder piston rod from bracing frame base plate pass beneath rod aperture after, cylinder upper end face band base board flange dish 3, base board flange dish is fixed on below bracing frame base plate, and piston rod end band support claw ring flange 5, support claw ring flange is fixed on below support claw.With roller 11 on support claw top, when workpiece rotates, roller 11 is in order to become sliding friction into rolling friction.
See Fig. 2, be arranged on by bracing frame on oblique lathe bed lathe saddle 6, thin and long shafts part 6 is placed on above support claw.7 is cutters.Operation process is, when cylinder piston rod stretches out, ejection support claw, by cylinder supports workpiece.Because cylinder gas pressure is adjustable, can according to workpiece concrete actual demand setting support force size; Again because pneumatic support is flexible support, not only eliminate workpiece deformation, vibrations, and when workpiece cutting back force is extremely excessive, workpiece has to produce deforming displacement, and supporting cylinder piston rod can return, thus protection machine tool is not damaged.
