Description

Bearing type overrunning clutch part cam etc. point groove face clamp for machining
Technical field
The utility model is related to machining technology field, more particularly to a kind of fixture of machining.
Background technology
The outer circumference surface of bearing type overrunning clutch part cam is provided with the decile groove coordinated with roller, as shown in figure 1, Decile groove 1 has surface roughness requirements, while each decile groove equal must just can guarantee that bearing-type to the cam center of circle apart from D Freewheel clutch normal work.Decile groove is formed generally by milling machine Milling Process, and usual way is with special in the industry now Fixture by cam clamping on the workbench of milling machine, process a decile groove, turning of work piece reprocesses next decile groove, Using manual indexing, cam outer circumference surface has 20 decile grooves to need 20 turning of work piece to complete processing, so not But efficiency is low, and the multiple hand-turning of workpiece its clamping precision may be affected because of the factor such as artificial, so influence plus Work precision.
The content of the invention
The purpose of this utility model is to provide a kind of bearing type overrunning clutch part cam etc. point groove face clamp for machining, energy The quality for effectively improve processing efficiency, improving machining accuracy and product is effectively ensured.
The technical scheme that the utility model is used to achieve the above object is:A kind of bearing type overrunning clutch part cam Decile groove face clamp for machining, including heart axle, expansion set, pressing plate, locking nut and NC dividing head, heart axle are connected to milling machine spindle Front end, expansion set is enclosed on heart axle excircle, and heart axle front end is connected with screw rod, and cam sleeve is outside expansion set, and pressing plate is enclosed on heart axle front end Screw rod it is outer and be pressed in expansion set front end face, pressing plate is pressed on expansion set front end face by locking nut by pad, and NC dividing head leads to The motor for crossing control circuit and milling machine spindle is connected.
Further technical scheme of the present utility model is:The expansion set is one circumferentially apertured discontinuous to setting Becket, the outer wall of expansion set is the smooth circumferential vertical with its end face, and the inwall of expansion set is gradually thickening from inside to outside Inner conical surface, heart axle external diameter is gradually reduced the interior draft identical male cone (strobilus masculinus) to be formed with expansion set from inside to outside, and heart axle inner end is protruded Boss provided with positioning cam inner side end.
The utility model bearing type overrunning clutch part cam etc. point groove face clamp for machining has the advantages that:Work Part is fixed on milling machine by clampings such as heart axle, expansion set, pressing plate, locking nuts, and pressing plate is compressed after expansion set, and what workpiece was seamless determines Position outside expansion set, workpiece will not running fix precision it is high, the rotational angle of heart axle is controlled in process by NC dividing head, it is real Existing automatic indexing, indexing is accurate, and the efficiency not only processed is compared with traditional handicraft and is increased substantially, the quality of product can also be obtained To more preferable guarantee.
With reference to the accompanying drawings and examples to the utility model bearing type overrunning clutch part cam etc. point groove face processing Fixture is further described.
Brief description of the drawings
Fig. 1 is the structural representation of cam;
Fig. 2 is the utility model bearing type overrunning clutch part cam etc. point groove face clamp for machining structural representation;
Fig. 3 is the structural representation of expansion set;
Fig. 4 is the profile of expansion set;
Drawing reference numeral explanation:1- etc. points of groove faces, 2- cams, 3- expansion sets, 4- locking nuts, 5- screw rods, 6- pads, 7- pressures Plate, 8- heart axles, 9- boss, 10- NC dividing heads, 11- gaps.
Embodiment
As shown in Figures 2 to 4, the utility model bearing type overrunning clutch part cam etc. point groove face clamp for machining, bag Heart axle 8, expansion set 3, pressing plate 7, locking nut 4 and NC dividing head 10 are included, heart axle 8 is connected to the front end of milling machine spindle, 3 sets of expansion set On the excircle of heart axle 8, the front end of heart axle 8 is connected with screw rod 5, and cam 2 is enclosed on outside expansion set 3, and pressing plate 7 is enclosed on the spiral shell of the front end of heart axle 8 Bar 5 is outer and is pressed in the front end face of expansion set 3, and pressing plate 7 is pressed on the front end face of expansion set 3, NC dividing head by locking nut 4 by pad 6 10 are arranged on the rear end of heart axle 8, and NC dividing head 10 is by controlling the motor of circuit and milling machine spindle to connect.Wherein expansion set 3 Be one circumferentially to the discontinuous becket provided with gap 11, the outer wall of expansion set 3 is the smooth circumferential vertical with its end face Surface, the inwall of expansion set 3 is gradually thickening inner conical surface from inside to outside, the external diameter of heart axle 8 be gradually reduced from inside to outside to be formed with it is swollen The interior draft identical male cone (strobilus masculinus) of set 3, the inner end of heart axle 8 is arranged in the prominent part of the boss 9 of the inner side end of positioning cam 2.
During work, expansion set 3 is enclosed on outside heart axle 8, then cam 2 to be processed is enclosed on outside expansion set 3, and expansion set 3 is pressed in pressing plate 7 Pressing plate 7 is pressed on the front end face of expansion set 3, expansion set 3 outside distending, workpiece after being compacted by front end face, locking nut 4 by pad 6 It is positioned at regard to seamless 11 outside expansion set 3, you can Milling Process is carried out to cam 2, completes numerical control after a decile groove face 1 is processed Dividing head 10 controls milling machine spindle and heart axle 8 to rotate a minute of angle together, after realizing that automatic indexing, main shaft stop operating Then next decile groove face 1 is processed, by that analogy until processing all decile groove faces 1, then locking nut 4 is unclamped, takes The workpiece for completing processing can be unloaded after lower platen 7, is increased substantially using the efficiency not only processed after the utility model fixture, The quality of product also can preferably be ensured.
Above example is only preferred embodiment of the present utility model, and structure of the present utility model is not limited to above-mentioned implementation The form that example is enumerated, all any modification, equivalent substitutions made within spirit of the present utility model and principle etc., it all should include Within protection domain of the present utility model.
