Abstract

The invention discloses an excircle turning center of an outer bell-shaped shell, which comprises a cylindrical clamping handle, a rotating body and a circular truncated cone, wherein the conical surface of the circular truncated cone is formed with tooth-shaped bulges with triangular sections, and the tooth-shaped bulges are arranged in an annular array along the axis of the circular truncated cone, and the excircle turning center has the advantages that: when the center is machined by the outer circle turning machining center of the bell-shaped shell, the influence that the concentricity cannot meet the requirement due to the precision deviation of the inner hole of the forge piece can be reduced, the original surface contact is changed into line contact, the tooth-shaped bulge can avoid the deviation position of the inner hole of the forge piece, and the center of a circle can be accurately found.

Description

Clutch can cylindrical Vehicle Processing is top
Technical field
The present invention relates to a kind of clutch can clamp for machining, specifically a kind of clutch can cylindrical Vehicle Processing is top.
Background technology
Cage clutch can is from the vitals of variator transmission wheel by the power of electromotor, the clutch can of cage compares high for cylindrical with the concentricity requirement of endoporus, the blank forging of clutch can forms, the aperture of clutch can is withstood in outer bowlder one end of processing clutch can, the other end props up the endoporus of clutch can by chuck, and owing to forging precision is the highest, the endoporus of clutch can blank is not positive round, the endoporus of the workpiece processed is low with the concentricity of cylindrical, affects the quality of product.
Summary of the invention
For solving the problems of the prior art, the present invention needs to provide a kind of can reduce the impact that forge piece inner hole precision is low, improves the top of workpiece concentricity.
For realizing above-mentioned technical problem, the present invention provides a kind of clutch can cylindrical Vehicle Processing top, the top grip shank including cylinder, rotary body and round platform, the taper surface of round platform forms the detent projection that cross section is triangle, and detent projection is arranged along round platform axis wire loop array.
Described rotary body one end has circular hole, grip shank one end forms cylindrical protrusions, and cylindrical protrusions sleeve is in the circular hole of rotary body, the cylindrical of grip shank and rotary body connects single direction thrust ball bearing, the seat ring sleeve of single direction thrust ball bearing is at the outer round surface of grip shank, the blowout patche sleeve of single direction thrust ball bearing is at the outer round surface of rotary body, described single direction thrust ball bearing makes to rotate against to a direction between grip shank and rotary body, it is connected by a unilateral bearing between rotary body with round platform, bearing groove is had on round platform large end face, unilateral bearing sleeve is in bearing groove, the outer peripheral surface of unilateral bearing is close to bearing groove medial surface, rotary body sleeve is on the inner ring of unilateral bearing, and it is close to inner peripheral surface, described unilateral bearing makes to rotate against to same direction between rotary body and round platform.
Described grip shank all has tank filler sleeve with rotary body center and is connected, and leaves gap between rotary body and bearing groove bottom surface, and tank filler sleeve gap is connected.
Described single direction thrust ball bearing is set in the same direction with the rotatable direction of unilateral bearing, freely rotates against to same direction, be the most then braked between grip shank, rotary body and round platform.
Described round platform material therefor is the one of carbon tool steel or high-speed tool steel, and its hardness is at HRC60~70.
The invention have the advantages that to add and use that the cylindrical Vehicle Processing of this clutch can is top can reduce the impact causing concentricity can not reach requirement because of forging inner hole precision deviation man-hour, linear contact lay is changed into by original contact, detent projection can be avoided, at the deviation of forging endoporus, accurately finding the center of circle.Top be clamped on lathe spindle time, unilateral bearing is contrary with lathe spindle forward direction with the rotatable direction of single direction thrust ball bearing, now, cannot rotate against between bare terminal end and round platform, and when top be clamped in main shaft opposite side time, unilateral bearing is identical with lathe spindle forward direction with the rotatable direction of single direction thrust ball bearing, can rotate against between bare terminal end and round platform, therefore, the top of the present invention can keep workpiece motionless as endoporus fixed clamp instrument, also workpiece can be made to rotate freely as regular centre, lubricating oil can be added in frequentation tank filler sleeve when routine use, lubricating oil can enter in the gap of all parts by tank filler sleeve, reduce the abrasion being mutually shifted generation between parts, extend top service life.

Detailed description of the invention
The specific embodiment of the present invention is described according to Fig. 1, it includes cylindrical top body, the top grip shank 1 including cylinder, rotary body 9 and round platform 2, the taper surface of round platform 2 forms the detent projection 3 that cross section is triangle, and detent projection 3 is arranged along round platform 2 axis annular array.
nullDescribed rotary body 9 one end has circular hole,Grip shank 1 one end forms cylindrical protrusions,And cylindrical protrusions sleeve is in the circular hole of rotary body 9,The cylindrical of grip shank 1 and rotary body 9 connects single direction thrust ball bearing 8,The seat ring sleeve of single direction thrust ball bearing 8 is at the outer round surface of grip shank 1,The blowout patche sleeve of single direction thrust ball bearing 8 is at the outer round surface of rotary body 9,Described single direction thrust ball bearing 8 makes to rotate against to a direction between grip shank 1 and rotary body 9,It is connected by a unilateral bearing 4 between rotary body 9 with round platform 2,Bearing groove 5 is had on round platform 2 large end face,Unilateral bearing 4 sleeve is in bearing groove 5,The outer peripheral surface of unilateral bearing 4 is close to bearing groove 5 medial surface,Rotary body 9 sleeve is on the inner ring of unilateral bearing 4,And it is close to inner peripheral surface,Described unilateral bearing 4 makes to rotate against to same direction between rotary body 9 and round platform 2.
Described grip shank 1 all has tank filler sleeve 7 with rotary body 9 center and is connected, and leaves gap between rotary body 9 and bearing groove 5 bottom surface, and tank filler sleeve 7 gap 6 is connected.
Described single direction thrust ball bearing 8 is set in the same direction with the rotatable direction of unilateral bearing 4, freely rotates against to same direction, be the most then braked between grip shank 1, rotary body 9 and round platform 2.
Described round platform 2 material therefor is the one of carbon tool steel or high-speed tool steel, and its hardness is at HRC60~70.
When clamping, when the top holding of needs is fixing need not rotate against time, need top clamping on the main shaft of lathe, the interior nose end sleeve of clutch can is on top, the inner bore chamfering of top detent projection 3 and clutch can is to contacting, the other end of clutch can uses lathe to carry the top center hole withstanding clutch can, when needs are top rotate against time, its clamping is carried top side at lathe, the interior nose end still sleeve of clutch can is on top, and the other end clamping of clutch can is on the chuck of lathe.
