It asks.
The two halves formula cam processed in the past, generally belongs to the spare part of diesel engine, in order to guarantee ontology in the process of running
Cam damage after replace it is efficient and convenient, usually between two half of cam directly use pin hole or bolted on connection, then anchor ear is in master
On axis.And certain cams are since structure or performance limit, cam two halves on piece is not coupled the pin hole or screw thread via hole of positioning, only
Boss is set in cam two sides, is arranged 3 at boss edge45 ° of chamfering, in order to guarantee that contour and assembly are splitted
Junction gap meets requirement, and the alternative scheme of fixing tool includes following two.
1, anchor ear tooling is designed, this is a kind of simple direct scheme, and anchor ear is arranged on the boss of cam two sides, will cut open
The two halves formula cam bit anchor ear opened is fixed, but since the design that boss axial width and cam profile etc. limit anchor ear is wanted
It asks, so that the design and manufacture of anchor ear are more difficult, is not suitable for industrial production.
2, design technology is bolted, but due to Hough cam two sides boss subtract it is very thin after quench-hardened case, in practical set
There is deformation when service bolt connects, is unable to reach the requirement of bolt locking.After removing service bolt simultaneously, Hough is also resulted in
Cam Internal Hole Deformation.

Specific embodiment
It elaborates with reference to the accompanying drawing to the present invention.
Referring to Fig. 1 to Fig. 3, shown in Hough cam 1, the first cam bit 1a and the second cam including two halves corresponding matching
Piece 1b, the first cam bit 1a and the second cam bit 1b collectively constitute complete Hough cam 1,1 two sides convex in Hough after merging
It is symmetrically arranged with boss 11,11 edge of boss is equipped with chamfering 13, and axial keyway 12 is equipped on 1 inner hole circumferential surface of Hough cam.
Referring to fig. 4 to Fig. 9, shown in Hough cam fixing tool, including mandrel 2, band Moving plate 4 and two locking annulus 3,
The band Moving plate 3 is set to 2 end of mandrel, and for connecting with process equipment, the band Moving plate 4 is equipped with perforative pin hole 41, makes
With driving pin to connect across pin hole 41 with process equipment, band moving mandrel 2 rotates.The process equipment is the common of cam cutting
Mechanical equipment repeats no more in the present invention.
The 2 both ends center of mandrel is equipped with the top heart hole 25 with the top corresponding matching of process equipment, which is
Blind hole, size are adjusted according to the top of process equipment.It is equipped with and 1 internal diameter of Hough cam in the middle part of 2 outer peripheral surface of mandrel
The construction section 22 of cooperation, mandrel 2 are respectively provided with the thread segment 21 of connection locking annulus 3 in the two sides for being located at construction section 22.
Locking 3 inner peripheral surface of annulus is equipped with internal screw thread 34 with 21 corresponding matching of thread segment, close to one end of Hough cam 1 be equipped with
The locking inclined-plane 33 of 13 corresponding matching of chamfering；The outer end diameter 31 of the one end of the locking annulus 3 close to Hough cam 1, which is less than, breathes out
The minimum outer diameter of husband's cam 1.Annulus 3, internal screw thread 34 and 21 corresponding matching of thread segment are locked by rotation, realizes locking annulus
3 along mandrel 2 axial movement, and then realize two locking annulus 3 to Hough cam close to or far from.
In order to guarantee that Hough cam 1 rotates jointly in grinding and detection process with mandrel 2, the construction section of the mandrel 2
22 are equipped with positioning spline 23 corresponding with 12 position of axial keyway, when Hough cam 1 is fixed, first in positioning key
Flat key is placed on slot 23, then two halves the first cam bit 1a of Hough cam 1 and the second cam bit 1b is merged, the Hough after merging
The axial keyway 12 and flat key corresponding matching of cam 1.2 peripheral surface of mandrel is equipped with corresponding with 23 position of positioning spline to just
Notch 24, the accurate centering of 12 angle of axial keyway, is always ensured that Kazakhstan after fixing to the setting of positive notch 24 convenient for Hough cam 1
Processing and detection benchmark and the keyway angle reference of design after the combination of husband's cam 1 is unified.
As a kind of preferred embodiment of the invention, 3 periphery of locking annulus is in two sections of step-like, small-diameter steps
31 end faces are engaged with Hough cam 1, and outer end diameter is less than the minimum outer diameter of Hough cam 1, avoid 1 essence of Hough cam
The minimum outer diameter of Hough cam 1 is interfered with locking annulus 3 when close grinding.32 periphery of major diameter step lacks there are four being all provided with
Mouthful, convenient symmetrical locking firmly uses.
As another embodiment of the invention, the material of the mandrel 2, locking annulus 3 and flat key is 45 steel, and
Tempering and Quenching is carried out, so that the fixing tool has enough rigidity.
A kind of processing method of Hough cam comprising following steps:
1) Hough cam 1 is fixed using above-mentioned fixing tool, flat key is placed on the positioning spline 23 of mandrel 2, then will breathe out
Two halves the first cam bit 1a and the second cam bit 1b merging of husband's cam 1 are assemblied on the construction section 22 of mandrel 2, the Kazakhstan after merging
The axial keyway 12 and flat key protrusion corresponding matching of husband's cam 1, then rotate locking annulus 3 and be axially moved along mandrel 2, from Kazakhstan
The two sides of husband's cam 1 come closer, and match by the way that the locking inclined-plane 33 on locking annulus 3 is corresponding with the chamfering 13 on Hough cam 1
It closes, gradually the opening of two halves the first cam bit 1a of Hough cam 1 and the second cam bit 1b is tightened, is fastened to a certain degree
Afterwards, the gap at the first cam bit 1a and the second relative position cam bit 1b is measured using clearance ruler, until gap be 0.05 ~
0.2mm completes the fixation of Hough cam 1.
2) the top heart hole 25 at 2 both ends of mandrel is driven into core by band Moving plate 4 respectively with corresponding matching top on equipment for grinding
Hough cam 1 on axis 2 is ground 1 outer profile of Hough cam around 2 axial-rotation of mandrel.
3) after the completion of being ground, band Moving plate 4 and mandrel 2 are removed from equipment for grinding, then the top heart hole 25 at 2 both ends of mandrel is divided
Not with corresponding matching top on detection device, 1 outer profile of Hough cam is detected.
Processing and detection can be completed using a set of fixing tool, reduce the waiting dismounting workpiece time, improve work
Efficiency.And after the completion of the processing detection of Hough cam 1, it is only necessary to screw out locking annulus 3 to Hough cam two sides along mandrel 2
Realize disassembly, it is convenient and efficient.Also, the peaceful bond energy of locking annulus 3 is enough to be assemblied in always on mandrel 2, it is not necessary to it removes, it is convenient entire
The storage keeping and use of fixing tool.
