Abstract
The invention discloses a cylindrical turning centre for bell housings. The centre comprises a cylindrical clamping handle, a rotator and a cone frustum, toothed protrusions with triangular sections are formed on the conical surface of the cone frustum, and the toothed protrusions are arranged in a ring array along the axis of the cone frustum. The cylindrical turning centre has the advantages that by the cylindrical turning centre for the bell housings, the influence that concentricity cannot meet the requirement due to forging inner-hole precision deviation can be reduced during processing, original surface contact is changed into line contact, the toothed protrusions can avoid the deviation positions of inner holes of forgings, and the center of a circle can be found accurately.
Description
Technical field
The present invention relates to a kind of clutch can clamp for machining, specifically the Vehicle Processing of a kind of clutch can cylindrical is top.
Background technology
Ball cage clutch can is the power of engine to be transmitted to the vitals of wheel from speed changer, the clutch can of ball cage is higher for the concentricity requirement of cylindrical and endoporus, the embryo part of clutch can forges and 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, because forging precision is not high, the endoporus of clutch can embryo part is not just to justify, the endoporus of the workpiece processing and the concentricity of cylindrical are low, affect the quality of product.
Summary of the invention
For solving the problems of the prior art, the present invention need 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 invention provides the Vehicle Processing of a kind of clutch can cylindrical top, top columniform grip shank, rotary body and the round platform of including, it is leg-of-mutton detent projection that the taper surface of round platform forms cross section, and detent projection arranges 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 is connected with 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 a direction, relatively to rotate between grip shank and rotary body, between rotary body and round platform, by a unilateral bearing, be connected, on round platform large end face, have bearing groove, unilateral bearing sleeve is in bearing groove, the surface, outer ring of unilateral bearing is close to bearing groove medial surface, rotary body sleeve is on the inner ring of unilateral bearing, and be close to inner peripheral surface, described unilateral bearing makes to same direction is relative, to rotate between rotary body and round platform.
Described grip shank all has tank filler sleeve and is connected with rotary body center, between rotary body and bearing groove bottom surface, leaves gap, and tank filler sleeve gap is connected.
The rotatable direction of described single direction thrust ball bearing and unilateral bearing is set in the same way, between grip shank, rotary body and round platform to same direction free phases to rotation, be oppositely braked.
Described round platform material therefor is a kind of of carbon tool steel or high-speed tool steel, and its hardness is in HRC60～70.
Advantage of the present invention: add and adopt man-hour top can the reducing of this clutch can cylindrical Vehicle Processing can not meet the requirements of impact because forging inner hole precision deviation causes concentricity, by original contact, changing line into contacts, detent projection can be avoided the deviation place of forging endoporus, accurately finds the center of circle.Top while being clamped on lathe spindle, unilateral bearing is contrary with lathe spindle forward direction with the rotatable direction of single direction thrust ball bearing, now, between bare terminal end and round platform, cannot relatively rotate, and when top while being clamped in the relative side of main shaft, unilateral bearing is identical with lathe spindle forward direction with the rotatable direction of single direction thrust ball bearing, between bare terminal end and round platform, can relatively rotate, therefore, it is of the present invention that top to can be used as endoporus fixed clamp instrument holding workpiece motionless, also can be used as regular centre rotates freely workpiece, when routine use, can in frequentation tank filler sleeve, add lubricating oil, lubricating oil can enter into by tank filler sleeve the gap of all parts, reduce the mobile wearing and tearing that produce mutually between parts, extend top service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the top clamp position of clutch can cylindrical Vehicle Processing;
Fig. 2 is the top cross section view of clutch can cylindrical Vehicle Processing;
In figure: 1, grip shank; 2, round platform; 3, detent projection; 4, unilateral bearing; 5, bearing groove; 6, gap; 7, tank filler sleeve; 8, single direction thrust ball bearing; 9, rotary body.
The specific embodiment
According to Fig. 1, specific embodiments of the invention are described, it comprises cylindrical top body, top columniform grip shank 1, rotary body 9 and the round platform 2 of including, it is leg-of-mutton detent projection 3 that the taper surface of round platform 2 forms cross section, and detent projection 3 arranges along round platform 2 axis annular arrays.
Described rotary body 9 one end have 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 is connected with 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 a direction, relatively to rotate between grip shank 1 and rotary body 9, between rotary body 9 and round platform 2, by a unilateral bearing 4, be connected, on round platform 2 large end faces, have bearing groove 5, unilateral bearing 4 sleeves are in bearing groove 5, the surface, outer ring of unilateral bearing 4 is close to bearing groove 5 medial surfaces, rotary body 9 sleeves are on the inner ring of unilateral bearing 8, and be close to inner peripheral surface, described unilateral bearing 8 makes to same direction is relative, to rotate between rotary body 9 and round platform 2.
Described grip shank 1 all has tank filler sleeve 7 and is connected with rotary body 9 centers, between rotary body 9 and bearing groove 5 bottom surfaces, leaves gap, and tank filler sleeve 7 gaps 6 are connected.
Described single direction thrust ball bearing 8 is set in the same way with the rotatable direction of unilateral bearing 4, between grip shank 1, rotary body 9 and round platform 2 to same direction free phases to rotating, be oppositely braked.
Described round platform 2 material therefors are a kind of of carbon tool steel or high-speed tool steel, and its hardness is in HRC60～70.
When clamping, when the top maintenance of needs is fixing while not needing relatively to rotate, need to be by top clamping on the main shaft of lathe, the interior nose end sleeve of clutch can is on top, top detent projection 3 with the inner bore chamfering of clutch can to contacting, the other end of clutch can is used lathe to carry the top center hole that withstands clutch can, when the top relative rotation of needs, its clamping to be carried to a top side at lathe, still sleeve is on top for the interior nose end of clutch can, and the other end clamping of clutch can is on the chuck of lathe.
