Description
Technical field
The utility model relates to a kind of fixture, is specifically related to a kind of power steering gear valve body drilling jig.
Background technology
Due to the increase of automobile self load-carrying and deadweight, before automobile overcomes in steering procedure, wheel drag also will increase along with front load per axle accordingly, thus requirement effect steering force is on the steering wheel enough large, so large power, only manpower is relied on to meet, therefore add in the steering of automobile and turn to augmentor, its principle is the power drive power assistance pump for steering relying on engine, increases the strength of pilot control front-wheel steer with fluid power.
According to power source form, power steering system can be divided into fluid pressure type, pneumatic type and electrodynamic type.Hydraulic power steering system is divided into permanent current formula and gerotor type according to the Process flow of fluid.Permanent current formula power steering system refers to that boost pump sucks fluid from oil tank, is discharged again by oil pump, gets back to oil tank through steering control valve in the form process of automobile, and fluid is in permanent current state always.Power steering stgear in permanent current formula power steering system is divided into side valve type and Revolving valve type power steering gear according to the form of control valve.Valve in Revolving valve type power steering gear comprises valve body.
Above-mentioned valve body needs bore symmetrical pin-and-hole, with the alignment pin clamping with steering screw.At present when valve body is holed, usual employing drill jig sleeve cylindrical clamping position valve body, mainly there is following problem: the conveniently dismounting of valve body, drill jig sleeve cylindrical and valve body are matched in clearance, therefore when clamping, valve body easily produces radial-play, causes pore volume easily to bore partially.
Utility model content
The utility model is intended to provide a kind of power steering gear valve body drilling jig, comparatively large to solve existing employing drill jig sleeve cylindrical clamping valve bore error, the problem that accuracy is low.
This programme is as follows: power steering gear valve body drilling jig, comprise the model drilling body of cuboid, length direction along model drilling body offers locating slot, the top of locating slot offers the drill bushing hole be communicated with locating slot, drill bushing hole is built with drill bushing, drill bushing is provided with boring, the axis of drill bushing is through the radial center of locating slot, the upper inside wall of locating slot has inverted V-shaped face, the longitudinal section, bottom of locating slot is square, two mounting grooves are offered along the axis of locating slot in the bottom interior wall of locating slot, backing plate is provided with in each mounting groove, the upper surface of backing plate has positive V-arrangement face, model drilling body is also provided with two holding screws, backing plate can be held out against by holding screw.
This programme clamping principle is as follows: valve body is inserted in locating slot vertically, valve body one end holds spacing by the bottom land of locating slot, tighten holding screw, the positive V-arrangement face of backing plate upper surface is made to hold out against the bottom cylindrical of valve body, the inverted V-shaped face of locating slot upper inside wall holds out against the top cylindrical of valve body, and drill bit is holed to valve body by the boring on drill bushing.
The utility model is by being arranged on the common clamping valve cylindrical in inverted V-shaped face in positive V-arrangement face on backing plate and locating slot upper inside wall, enough clamping forces are provided by holding screw, and arrange two backing plates to position valve body, two supporting surfaces are had to valve body, stability when valve body clamps can be guaranteed, prevent valve body from producing radial-play, prevent boring from occurring deviation.
Further, in order to make the lower surface of drill bushing also can have positioning action to valve body cylindrical, the lower surface of drill bushing has coordinate with valve body cylindrical 120
oinner conical surface.
Further, in order to prevent drill bushing from axially producing play along it, the end face of drill bushing is by being arranged on the drill bushing screw in compression in model drilling body.
Further, in order to make the position of drill bushing more stable, prevent its side direction play, drill bushing screw has four, is distributed on the border of drill bushing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
