No matter whether it is installed or disassembled, there is no need to change the original operating habits, the processing time is also greatly shortened, and the efficiency and reliability are high.
Description
Technical field
The utility model relates to the auxiliary clamp of annular thin wall part machined into, especially relates to the mandrel that is used for the processing of annular thin wall part cylindrical.
Background technology
Annular thin wall part is thinner because of its thickness, rigidity deficiency diametrically, so difficulty of processing is bigger.Traditional processing technique of annular thin wall part is directly to be installed in annular thin wall part on the spindle chuck, consequent problem is: chuck location directly upwards deforms annular thin wall part easily at it, and causes temperature distortion in the process because of the depth of cut is excessive.In view of the situation, for the stationary annular thin-wall part is avoided directly workpiece radially being produced fastening stressed effect, when design annular thin wall part processing tool, radially be not fixed at annular thin wall part, and adopt by auxiliary mould axially being located at annular thin wall part, can avoid effectively being out of shape, guarantee the machining accuracy of annular thin wall part, improve the workpiece passing rate of processing because of workpiece is subjected to claw to clamp the stressed workpiece radial dimension that produces.
The utility model content
Add man-hour in order to solve annular thin wall part, traditional localization method makes the problem of workpiece deformation easily, and the utility model provides the mandrel in the annular thin wall part cylindrical processing tool external member.
The utility model is that the technical scheme that its technical problem of solution is adopted is,
Annular thin wall part cylindrical processing mandrel, be used for the processing of annular thin wall part cylindrical, with locking cover plate, the supporting use of lock-screw, annular thin wall part is fixed, comprise the mandrel body, described mandrel body is cylindrical, and an end of mandrel body protrudes a step cutting pattern, and described step central part is provided with a screwed hole.
The external diameter of described step is than the little 0.03～0.05mm of internal diameter of the annular thin wall part of processing.
The screw thread of described screwed hole and the external screw thread on the lock-screw match.
Big 1～the 1.5mm of height of the annular thin wall part that aspect ratio is processed of described step.
The external diameter of described mandrel body is than the little 3～5mm of external diameter of the annular thin wall part of processing.
In the annular thin wall part processing, annular thin wall part is nested in purpose made technology outside diameter of mandrel, axially fasten location at annular thin wall part at it by the locking cover plate, to improve the rigidity that thin-wall part adds man-hour, make workpiece radially not be subjected to external force, guarantee the precision of annular thin wall part processing effectively, improve the workpiece passing rate of processing, meet the design size requirement.
The beneficial effects of the utility model are, the mandrel process structure that is provided is simple, and no matter easily processing installs still dismounting, need not to change original operating habit, and also shorten greatly process time, efficient and reliability height.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
The making material selection brass H62 of annular thin wall part cylindrical processing mandrel, this material plasticity is good, hardness is low, coefficient of friction is little, the good mechanical performance is arranged, easily cutting particularly has self lubricity (need not to add cutting fluid and also can turning go out the high surfaces precision) when High-speed machining, be fit to turning processing, even the depth of cut is big in the processing, also be difficult for producing sticking cutter or penetration of a cutting tool phenomenon when cutting speed is higher.
Copper belongs to the good conductor of heat transfer, perfect heat-dissipating, the heat that the workpiece work in-process is produced can be dispersed in time, makes workpiece be difficult for producing because of the machined heating becomes and produces the phenomenon of swelling, make that the passive support of annular retaining ring that is enclosed within on the external diameter is big, influence final workpiece size.
The structure of annular thin wall part cylindrical processing mandrel 30 as shown in Figure 1 and Figure 2, mandrel body 31 is cylindrical, an end of mandrel body 31 protrudes a step cutting pattern 32, described step 32 central parts are provided with a screwed hole 33.
The size relationship of mandrel and annular thin wall part, locking cover plate and lock-screw as shown in Figure 3, the outer diameter D 3 of step is than the little 0.03～0.05mm of internal diameter of the annular thin wall part of processing, make processed annular thin wall part can pack into mandrel fully, and can with processing chuck axis coinciding, obtain centralized positioning accurately.
The screw thread of screwed hole and the external screw thread on the lock-screw match.
The height L of step is than the big 1～1.5mm of height H of the annular thin wall part of processing.
The outer diameter D 2 of mandrel body is than the outer diameter D 1 little 3～5mm of the annular thin wall part of processing.
Fig. 4 is the schematic diagram that lock-screw and locking cover plate, mandrel, chuck are used the stationary annular thin-wall part.Mandrel 30 is gripped by chuck 40 during use, annular thin wall part 50 places on the mandrel 30, the lid of locking cover plate 20 is along annular thin wall part is pushed down, the through hole of lock-screw 10 by locking cover plate 20 lid end central authorities put in the screwed hole of mandrel 30, screwing lock-screw can fix annular thin wall part again.
In the annular thin wall part processing, annular thin wall part is nested in the external diameter of mandrel step cutting pattern, axially fasten location at annular thin wall part at it by the locking cover plate, because the locking cover plate is fixed in annular thin wall part on the mandrel in the axial direction, not to radially the exerting pressure of annular thin wall part, can not produce radial deformation because of the reason of fixed form, guarantee the precision of annular thin wall part processing effectively, improve the workpiece passing rate of processing, meet the design size requirement.
Mandrel process structure provided by the utility model is simple, and no matter easily processing installs still dismounting, need not to change original operating habit, and also shorten greatly process time, efficient and reliability height.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
