Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.

As it is shown in figure 1, a kind of frock for machining cam axle vent of the present utility model, including base 1, It is arranged on base 1 support member 2 for horizontal support camshaft 5, is arranged on above relief groove for by convex Keeper 3 that wheel shaft is pressed on support member 2, it is arranged on base 1 for driving keeper 3 to move up and down Guiding driving mechanism 4, this keeper 3 includes for being arranged on guiding driving mechanism 4 by keeper 3 Installation portion 31 and cooperation abut in the location division 32 of relief groove 51 side, and this location division 32 is provided with for right The pilot hole 321 that drill bit guides.

Wherein, guiding driving mechanism 4 includes that the column 41 being arranged on base 1, engagement sleeves are contained in column 41 On sliding sleeve 42, for connect keeper 3 and sliding sleeve 42 connector 43, be arranged on base 1 for Drive the actuator 44 that sliding sleeve 42 slides up and down along column 41.Concrete, in the present embodiment, this connector 43 is plate-shaped, and keeper 3 is arranged on the upper surface of connector 43 by bolt, and sliding sleeve 42 is set by bolt Put the lower surface at connector 43；As it is shown on figure 3, the cross section of this column 41 is trapezoidal；This actuator 44 is cylinder, and actuator 44 is arranged between base 1 and connector 43, say, that the cylinder body of this cylinder Be arranged on base 1, the piston of cylinder is arranged on connector 43.Certainly, in specific implementation process, The cross section of column 41 can also be circular, square, triangle or other shapes, as long as sliding sleeve 42 is interior Hole is mated with the outline of column 41；And actuator 44 is alternatively oil cylinder, electric pushrod etc., as long as Sliding sleeve 42 can be driven along column 41 movement slip；It addition, actuator 44 may also be arranged on base 1 with Between sliding sleeve 42.

Wherein, support member 2 is two pieces of bracers 21 be arrangeding in parallel, and this bracer 21 is provided with V-groove 22, the axle journal at the two ends of camshaft 5 lays respectively in the V-groove 22 of two bracers 21.Certainly, at tool In body implementation process, it is possible to use U-type groove or other structures to carry out spacing to axle journal.

During work, first this frock is fixed on the work platforms of drilling machine or other lathes；Then, by cam Axle 5 is placed on support member 2 so that it is the axle journal at two ends is positioned at the V-groove 22 of two bracers 21, and makes The relief groove 51 of camshaft is placed upward；Control actuator 44 again so that it is drive connection part 43, sliding sleeve 42 And keeper 3 moves to the direction at camshaft place with column 41 simultaneously, meanwhile, move axially camshaft, The side making its relief groove 51 abuts on location division 32, and is pressed on location division 32 on this relief groove 5； Finally control drilling machine or the drill bit of other lathes so that it is drill bit creeps into through pilot hole 321.

Tool structure of the present utility model is simple, and this work fills in the face of camshaft on the basis of the side of relief groove Clamp position, eliminate the cumulative error caused because of clamping；Meanwhile, utilize the pilot hole on keeper to drill bit Position of creeping into be controlled, improve machining accuracy, improve the qualification rate of product.

Optimize, as in figure 2 it is shown, the upper surface of connector 43 be provided with for engage installation portion 31 first Draw-in groove 431, the lower surface of connector 43 is provided with the second draw-in groove 432 for engaging sliding sleeve 42.This first card Groove 431 makes more stable being fixed on connector 43 of keeper 3, the connector that this second draw-in groove 432 is 43 is the most firm with the connection of sliding sleeve 42, can prevent in the course of processing, keeper generation play, it is ensured that subtract The machining accuracy in pressure hole 511.

Optimize, as it is shown in figure 5, the inner surface of V-groove 22 is provided with the first hard alloy layer 23, can carry The abrasion resistance of high V-groove 22 inner surface, reduces because frequently using the abrasion causing V-groove 22, reduces The deformation of this V-groove 22, improves the service life of this frock.

Optimizing, location division 32 is provided with the second hard alloy layer 323, this second hard alloy layer 323 On the surface fitted with relief groove.Owing to the lower surface of location division 32 pastes with relief groove 51 in the course of processing Closing, in drilling process, the lower surface of location division 32 can produce abrasion, this second hard alloy layer 323, can Reduce abrasion, improve the service life of this frock.

As the improvement of such scheme, it is equipped with in pilot hole 321 and is provided with drill bushing 322.Concrete, this brill Set 322 includes being equipped with at the shell-like body of pilot hole 321 and is arranged on the flange on this shell-like body. During assembling drill bushing 322, only shell-like body fits need to be placed in pilot hole 321, now, at gravity Effect under, drill bushing 322 can fall, and its lip fits completes in the upper surface of location division 32, assembling.Should Drill bushing easy accessibility, for the camshaft of different model, the aperture of vent is different, by changing internal diameter not Same drill bushing, can make frock of the present utility model be applicable to the drill bit of various outer diameter；It addition, when drill bushing grinds Drill bushing is directly changed, it is not necessary to change whole frock, saved production cost after damage.

Finally illustrating, preferred embodiment above is only in order to illustrate the technical solution of the utility model rather than limit System, although this utility model being described in detail by above preferred embodiment, but this area It will be appreciated by the skilled person that in the form and details various change can be made for it, and the most inclined From this utility model claims limited range.
