Abstract

An internal processing mandrel for annular thin-wall parts is used for processing of the annular thin-wall parts and used with a locking cover plate to fix the annular thin-wall parts. The internal processing mandrel comprises a mandrel body, the mandrel body is tubular, one end of the mandrel body is protruded to form a ring step of an annular thin-wall part to be processed, the outer side of the step is provided with external threads, and the external threads are matched with internal threads of the locking cover plate. During internal processing of the annular thin-wall part, the annular thin-wall part is nested on the inner diameter of the ring step of the special processed mandrel, the annular thin-wall part is fastened and positioned through the locking cover plate axially so that processing rigidity of the annular thin-wall part is increased, radial stress on workpieces is avoided, processing precision of the annular thin-wall part is guaranteed effectively, processing pass rate of the workpieces is increased and requirements on designed dimension are met. In addition, the mandrel is simple in process and structure, easy to process and free of changing original operation habits regardless of installation or detachment, and processing time is shortened greatly and processing efficiency and reliability are high.

Description

Circle processing mandrel in the annular thin wall part
Technical field
The present invention relates to the auxiliary clamp of annular thin wall part machined into, especially relate to the mandrel that is used for circle processing in the annular thin wall part.
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.
Summary of the invention
Add man-hour in order to solve the shape thin-wall part, traditional localization method makes the problem of workpiece deformation easily, the invention provides the mandrel in the circle processing tool external member in the annular thin wall part.
The technical scheme that the present invention is adopted for its technical problem of solution is,
Circle processing mandrel is used for annular thin wall part processing in the annular thin wall part, with the supporting use of locking cover plate, annular thin wall part is fixed, comprise the mandrel body, described mandrel body is the pipe shape, and mandrel body one end protrusion one can be placed the circular step of the annular thin wall part of processing.
The described step outside is provided with external screw thread, and described external screw thread matches with the internal thread of locking cover plate.
The internal diameter of described step is than the big 0.03~0.05mm of external diameter of the annular thin wall part of processing.
Little 1~the 1.5mm of height of the annular thin wall part that aspect ratio is processed of described step.
The internal diameter of described mandrel body is than the big 3~5mm of internal diameter of the annular thin wall part of processing.
During circle is processed in the annular thin wall part, annular thin wall part is nested in the internal diameter of the circular step of purpose made technology mandrel, by the locking cover plate annular thin wall part is axially fastened the location at it, 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 invention has the beneficial effects as follows that the mandrel process structure that is provided is simple, no matter easily processing installs still dismounting, need not to change original operating habit, and also shorten greatly process time, efficient and reliability height.
Description of drawings
Fig. 1 is the cutaway view of circle processing mandrel in the utility model annular thin wall part;
Fig. 2 is the dextrad view of Fig. 1;
Fig. 3 is the size relationship figure of mandrel and annular thin wall part;
Fig. 4 is the user mode figure of mandrel;
Among the figure, 10. lock cover plate, 20. mandrels, 21. mandrel bodies, 22. steps, 30. chucks, 40. annular thin wall parts.
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 circle processing mandrel in the annular thin wall part, 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 circle processing mandrel 20 as shown in Figure 1 and Figure 2 in the annular thin wall part, mandrel body 21 is the pipe shape, mandrel body one end protrusion one can be placed the circular step 22 of the annular thin wall part of processing, and step 22 outsides are provided with external screw thread, and described external screw thread matches with the internal thread of locking cover plate.
The size relationship of mandrel and annular thin wall part as shown in Figure 3,
Size according to annular thin wall part, the inside diameter D 2 of step is than the big 0.03~0.05mm of external diameter of the annular thin wall part of processing, not only make processed annular thin wall part can pack into the circular step of mandrel fully, and can with the chuck axis coinciding, obtain centralized positioning accurately;
The height L of step is than the little 1~1.5mm of height H of the annular thin wall part of processing;
The inside diameter D 1 of mandrel body is than the big 3~5mm of internal diameter of the annular thin wall part of processing.
In the annular thin wall part use of circle processing mandrel as shown in Figure 4, mandrel 20 is gripped by chuck 30 during use, annular thin wall part 40 places on the mandrel 20, locking cover plate 10 is tightened on the circular step of mandrel 20, and annular thin wall part 40 is fixed.
By the locking cover plate annular thin wall part is axially fastened the location at it,, 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 to improve the rigidity that thin-wall part adds man-hour.
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.
