Abstract
The utility model provides a drilling fixture for a balance shaft positioning hole. The drilling fixture comprises a bottom plate. Supporting frames are fixedly arranged on the two sides of the bottom plate along the length direction. A positioning support is fixedly arranged at the central part of the bottom plate. A support which extends outwards is fixedly arranged on the external side of one supporting frame. An axial positioning screw is arranged on the support. A transition cushion block is fixedly arranged on the positioning support. A guide groove is arranged on the transition cushion block along the length direction. The supporting cushion block is guided in the guide groove by connecting with a guide key. The supporting cushion block is used for being in contact with the bent position of a balance shaft to position the angle. A V-shaped block with a horizontal opening is fixedly arranged on the supporting frame. A pressing sliding block is arranged on the supporting frame in a direction corresponding to the V-shaped block and is driven through an air cylinder which is fixedly arranged on the supporting frame. A drilling template is fixedly arranged on the supporting plate. The drilling fixture for the balance shaft positioning hole has the advantages that the influence of outer diameter tolerance of the balance shaft can be avoided, the clamping stability and the clamping reliability are high and the machining quality is improved. The effect that kinds of balance shafts with shaft outer diameters which are not greatly changed share one set of fixture can be realized.
Description
Technical field
The utility model relates to a kind of boring grab that is used for the trunnion shaft locating hole.
Background technology
Existing, bore the locating hole at the trunnion shaft two ends of automobile balance suspension, used anchor clamps mainly are made up of V-block, pressing plate, locating piece etc.; The V-block opening makes progress, and vertical direction compresses trunnion shaft through pressing plate, and the axle crook of trunnion shaft contacts orientation angle with locating piece; The equipment that this operation is used is a horizontal double power drilling machine, and from side direction boring, drill bit level height and horizontal range are unadjustable; The trunnion shaft external diameter has tolerance; So the center line of axle can not remain at a level height under the support of V-block constant, cause the trunnion shaft external diameter to change as if change of product, also can not realize; And thrust is downward, and is bad from side direction boring stress.Because an axle crook black skin contacts with locating piece, need hole at twice the time, a relative slip with locating piece of crook black skin also can bring the error of hole symmetry when the two locating hole distances and the drill bit horizontal range of trunnion shaft are unequal.
Summary of the invention
In order to realize boring the influence that locating hole does not receive trunnion shaft external diameter tolerance variation; The two locating hole distances of avoiding trunnion shaft are unequal and guarantee the hole symmetry need hole at twice the time with the drill bit horizontal range; Improve crudy, the utility model provides a kind of boring grab that is used for the trunnion shaft locating hole.
The technical scheme of the utility model is: a kind of boring grab that is used for the trunnion shaft locating hole; Comprise base plate, be fixed with bracing frame in both sides along its length, be fixed with locating support at the middle part of base plate at base plate; Be fixed with outward extending support in the outside of a bracing frame; Support is provided with the axial location screw, it is characterized in that: be fixed with a transition cushion block on the locating support, the transition cushion block is provided with guide groove along its length; Support backing plate and in guide groove, lead, support backing plate and be used for contacting orientation angle with the axle crook of trunnion shaft through connecting a feather key; Be fixed with the V-block of along continuous straight runs opening on the bracing frame, direction corresponding with V-block on the bracing frame is provided with pressed slider, and pressed slider is through being fixed on the air cylinder driven on the bracing frame; Be fixed with bushing plate on the bracing frame.
Beneficial effect: the V-block along continuous straight runs opening of the utility model, trunnion shaft can remain at a level height under the support of V-block constant, can avoid the influence of trunnion shaft external diameter tolerance; Thrust with from side direction boring receive force direction consistent, clamping is reliable and stable, has improved crudy.If the trunnion shaft kind changes and causes an external diameter to change under the little situation, can realize the shared sleeve clamp of trunnion shaft of a plurality of kinds.

Fig. 2 be among Fig. 1 along A to view.
Fig. 3 is the vertical view of the utility model.
The specific embodiment
Like Fig. 1,2, shown in 3, it is following to further describe the utility model: a kind of boring grab that is used for the trunnion shaft locating hole comprises base plate 1; Be fixed with bracing frame 2 in both sides along its length at base plate; Be fixed with locating support 7 at the middle part of base plate, be fixed with outward extending support 3 in the outside of a bracing frame, support is provided with axial location screw 4; Be fixed with a transition cushion block 9 on the locating support; Transition cushion block 9 is provided with guide groove along its length, supports backing plate 8 and leads in guide groove through connecting a feather key 10, supports backing plate 8 and is used for contacting orientation angle with the axle crook of trunnion shaft 6; Be fixed with the V-block 5 of along continuous straight runs opening on the bracing frame 2, the direction corresponding with V-block is provided with pressed slider 13 on the bracing frame, and pressed slider 13 drives through the cylinder 11 that is fixed on the bracing frame; Be fixed with bushing plate 12 on the bracing frame 2.
As shown in Figure 2, on bracing frame 2, be fixed with auxiliary cushion block 14, be that the axle journal of trunnion shaft 6 is pushed into V-block 5 supplemental support before.
As shown in Figure 2, be fixed with wear-resisting cushion block 15 on the supporting surface of V-block 5, be convenient to support, change or maintenance.
Claims (3)
