Abstract
The utility model provides a drilling fixture for a positioning hole of a balance shaft, which comprises a bottom plate. Support frames are fixed at both sides of the bottom plate along the length direction; a positioning bracket is fixed at the middle part of the bottom plate; a positioning block is fixed on the positioning bracket; the positioning block is used for being contacted with a shaft bending position of the balance shaft to position an angle; a bracket extending outwards is fixed outside one support frame; an axial positioning screw is arranged on the bracket; V-shaped blocks which are provided with openings along the horizontal direction are fixed on the support frames; pressing sliding blocks are arranged on the support frames in the direction corresponding to the V-shaped blocks; the pressing sliding blocks are driven by cylinders fixed on the support frames; and drill plates are fixed on the support frames. According to the utility model, the V-shaped blocks are provided with the openings along the horizontal direction, so that the balance shaft can be always and constantly kept at a horizontal height under the support action of the V-shaped blocks and the influence of the outer diameter tolerance of the balance shaft can be avoided; and the pressing force is consistent with the stress direction of drilling in the side direction, the drilling fixture is stable and reliable to install and the processing quality is improved.
Description
Technical field
The utility model relates to the 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.
Summary of the invention
In order to realize boring the influence that locating hole does not receive trunnion shaft external diameter tolerance variation, improve crudy, the utility model provides the boring grab that is used for the trunnion shaft locating hole.
The technical scheme of the utility model is: the 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 at base plate; Middle part at base plate is fixed with locating support, is fixed with locating piece on the locating support, and locating piece is used for contacting orientation angle with the axle crook of trunnion shaft; 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: the V-block that is fixed with the 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. 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: the boring grab that is used for the trunnion shaft locating hole; Comprise base plate 1, be fixed with bracing frame 2 in both sides along its length, be fixed with locating support 7 at the middle part of base plate at base plate; Be fixed with locating piece 8 on the locating support 7, locating piece 8 is used for contacting orientation angle with the axle crook of trunnion shaft 6; 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 the V-block 5 of along continuous straight runs opening on the bracing frame; The direction corresponding with V-block is provided with pressed slider 10 on the bracing frame, and pressed slider drives through the cylinder 9 that is fixed on the bracing frame; Be fixed with bushing plate 13 on the bracing frame.
As shown in Figure 2, on bracing frame 2, be fixed with auxiliary cushion block 11, 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 12 on the supporting surface of V-block 5, be convenient to support, change or maintenance.
