Abstract
The utility model discloses a frock for thin wall tube -shape part prevents that thin wall tube -shape part clamping warp. This frock includes the axle core of encapsulation in thin wall tube -shape part, and the axle is provided with on the core fixes the rigid joint portion on the frame with the frock, the clamping portion that is provided with on the axle core. Set up clamping portion on the axle core, avoided direct to thin wall tube -shape part clamping and the clamping deformations problems who brings.
Description
Technical field
The utility model relates to tool structure, particularly a kind of frock for thin-walled tubular piece.
Background technology
When processing thin-walled tubular part, because the particularity of thin-walled parts, particularly when thin-walled tubular piece material is low-expansion alloy, when the wall thickness of processing thin-walled part circumference needed for applicant only has again below 0.5mm, such thin-walled tubular piece because of material softer, intensity is low, easily scratches, easily sticky cutter, sticky cutter forms built-up edge, thus applicant finds, so just allows clamping very difficult, adopt general clamping method, as chuck can allow thin-walled tubular piece very easily produce clamping deformation; When thin-walled tubular piece is provided with boss again, just need with five-axle linkage processing, milling amount is large, and cutting force and heat in metal cutting also can cause thin-walled tubular piece to be out of shape, and when machining hole, the precision in hole can be influenced.
Utility model content
The utility model aims to provide a kind of frock for thin-walled tubular piece, clamping deformation when preventing thin-walled tubular piece.
For a frock for thin-walled tubular piece, this frock comprises the axle core of encapsulation in thin-walled tubular piece, axle core is provided with fixing combination portion frock be fixed on support, and the cylindrical of axle core is provided with clamping device.
First this frock is arranged on support by fixing combination portion, by thin-walled tubular piece being set on axle core, thin-walled tubular piece is added to the situation appearance just can not worried man-hour making distortion during thin-walled tubular piece Excircle machining to thin-walled tubular piece, the cylindrical of axle core is provided with clamping device, avoids the clamping deformation problem directly thin-walled tubular piece clamping brought.
Further, described clamping device is ring flange.
The clamping device that axle core is arranged is ring flange, that is on thin-walled tubular piece, also should process corresponding flange dock with the ring flange on axle core, ring flange is stressed; the flange on thin-walled tubular piece is close to frock, can not cause flange distortion, and thin-walled tubular piece can not bear axial force; this avoid clamping deformation; very applicable to thin-walled tubular piece, adopts ring flange to be clamping device like this, is a kind of simple and practical and mode of economy.
Further, described ring flange and thin-walled tubular piece contact surface surface roughness Ra≤1.6 μm.
Further, described ring flange is provided with 10-16 hole.
This ring flange can be the ring flange of standard specification, can be also nonstandard of flanges dish, arrange 10-16 hole, and weigh processing cost and stressing conditions, arranging 10-16 hole is that one is preferably selected.When the hole on ring flange is screwed hole, screw just can be adopted to dock with thin-walled tubular piece, and certainly, thin-walled tubular piece also just should process corresponding screw thread.
Further, described axle core comprises suit portion and reference section, and clamping device is arranged between suit portion and reference section, and suit portion is provided with cannelure near clamping device part.
Here cannelure has the effect of escape, and namely cannelure here has and prevents thin-walled tubular piece corner from contacting with the corner of frock and the suit brought, be close to insufficient problem.
Further, described suit portion and reference section surface roughness Ra≤0.8 μm.
Here surface roughness is the smaller the better, but after considering economic factor, surface roughness Ra≤0.8 μm just can meet clamping requirement.
Further, the monolateral gap between described suit portion and this thin-walled tubular piece is 0-0.03mm.
Further, take reference section as benchmark, described suit portion relative to the axiality of reference section at below 0.015mm.
Further, described axle core two ends have chamfering.
Further, described fixing combination portion is flange plate structure.
The beneficial effects of the utility model:
First this frock is arranged on support by fixing combination portion, by thin-walled tubular piece being set on axle core, man-hour is added to thin-walled tubular piece, just the situation appearance to making distortion during thin-walled tubular piece Excircle machining to thin-walled tubular piece can not worried, the cylindrical of axle core is provided with clamping device, avoids the clamping deformation problem directly thin-walled tubular piece clamping brought.

Detailed description of the invention
Embodiment will be described below in conjunction with accompanying drawing to elaborate the utility model.
A kind of frock described by the present embodiment is directed to the part of thin-walled tubular structure, and described part should process flange arrangement.
This frock comprises the axle core 1 of encapsulation in thin-walled tubular piece, the cylindrical of axle core 1 is provided with ring flange 2, described ring flange 2 is adaptive with the screwed hole on the flange arrangement on thin-walled tubular piece, ring flange is connected by screw 3 with the flange arrangement that thin-walled tubular piece is processed, this ring flange 2 and thin-walled tubular piece contact surface surface roughness Ra=1.6 μm, ring flange 2 is provided with 12 holes, the screwed hole on the flange arrangement on corresponding thin-walled tubular piece is also 12; This axle core 1 is divided into reference section 101 and suit portion 102, described suit portion 102 and this thin-walled tubular piece contact internal walls, and the monolateral gap between this thin-walled tubular piece inwall is 0-0.03mm, surface roughness Ra=0.8 μm of suit portion 102 and reference section 101, the axiality of described suit portion 102 and reference section 101 is 0.015mm, and axle core 1 two ends all have chamfering.
Axle core is provided with the fixing combination portion 4 frock be fixed on support, this fixing combination portion 4 is flange plate structure, this frock is installed on by bolt on the mount pad of five-axis robot lathe, again thin-walled tubular piece is sleeved in this frock, with screw 3, the ring flange 2 on axle core 1 be connected with the flange arrangement on thin-walled tubular piece and fix, five-axle linkage processing can be carried out to this thin-walled tubular piece.By thin-walled tubular piece being set on axle core 1, man-hour is added to thin-walled tubular piece, just the situation appearance to making distortion during thin-walled tubular piece Excircle machining to thin-walled tubular piece can not worried, by arranging ring flange 2 on axle core 1, ring flange 2 is stressed, and the flange on thin-walled tubular piece is close to frock, can not flange distortion be caused; thin-walled tubular piece can not bear axial force, this avoid clamping deformation, very applicable to thin-walled tubular piece.
