Abstract
The utility model discloses a locking screw for excircle processing of circular-thin-wall parts, which comprises a nut and a screw rod, wherein the nut is connected at one end of the screw rod, the screw rod is provided with threads, the cross section of the nut takes the shape of half moon formed by two opposite arc edges and two opposite straight edges, the screw rod is provided with a tool withdrawal groove at the connection part with the nut, and four corners of the nut are fillets. The locking screw has appropriate operating hand feel, is convenient to use and easy to process, and has a simple technical structure and is low in manufacturing cost. The locking screw is used in match with other mating tools, and fixed on an circular-thin-wall part axially, thus improving the rigidity of the thin-wall part when in processing, enabling a workpiece not to be stressed by external force, effectively guaranteeing the processing precision of the circular-thin-wall parts, improving the qualification rate of processed workpieces, and meeting the requirement on design size.
Description
Technical field
The utility model relates to the auxiliary clamp of annular thin wall part machined into, especially relates to the lock-screw 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 annular thin wall part cylindrical processing tool supporting lock-screw.
The utility model is that the technical scheme that its technical problem of solution is adopted is,
Annular thin wall part cylindrical processing lock-screw comprises nut and screw rod, and nut is connected in screw rod one end, and screw thread is arranged on the screw rod, and the cross section of described nut is the first quarter moon waist shape of two circular arc opposite side and two straight line opposite side formation.
Described screw rod is provided with escape at itself and nut junction.
The circle footpath of described nut two circular arc opposite side is than the big 6～10mm of the diameter of thread on the screw rod.
The thickness of described nut is 8～10mm.
The angle is a fillet around the described nut.
The width of described escape is 3～5mm, and its diameter is than the little 0.5mm of the diameter of thread on the screw rod.
In the annular thin wall part processing, lock-screw and locking cover plate, mandrel are used, axially being fixed of annular thin wall part, 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 nut operating handle of its first quarter moon waist shape of the lock-screw that is provided is suitable, screw still pine and open all and put forth effort easily, and are easy to use, and process structure is simple, easily processing, and cost of manufacture is low.
Description of drawings
Fig. 1 is the structural representation of the utility model annular thin wall part cylindrical processing lock-screw;
Fig. 2 is the dextrad view of Fig. 1;
Fig. 3 is the use schematic diagram of lock-screw;
Among the figure, 10. lock-screw, 11. nuts, 12. screw rods, 13. escapes, 20. locking cover plates, 30. mandrels, 40. chucks, 50. 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 annular thin wall part cylindrical processing lock-screw, this material plasticity is good, hardness is low, and coefficient of friction is little.The good mechanical performance is arranged, and 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, and makes that the passive support of annular retaining ring that is enclosed within on the external diameter is big, influences final workpiece size.
Selection also can be adopted other metal materials except selecting brass H62 for use, as 45 steel etc.
The structure of annular thin wall part cylindrical processing lock-screw as shown in Figure 1, 2.The cross section of its nut is a first quarter moon waist shape as shown in Figure 2, and the angle is a fillet around the nut, can the adversary not cause sense of discomfort during operation.
The circle footpath D of nut is than the big 6～10mm of diameter of thread M.
The thickness H of nut is 8～10mm, and feel was the most suitable when this highly operated, and no matter screws still pine and open and can both bring into play to such an extent that exert oneself.
Fig. 3 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.
Because the locking cover plate is fixed in annular thin wall part on the mandrel in the axial direction, radially exerting pressure not to 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.
The nut operating handle of its first quarter moon waist shape of lock-screw is suitable, screws still pine and opens all and put forth effort easily, and is easy to use, and process structure is simple, easily processing, and cost of manufacture is low.
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.
