Description
Technical field
The present invention relates to auto parts and components pick-up unit, be specifically related to a kind of steering nut and return the hole of bead and screw thread raceway relative position degree pick-up unit.
Background technology
Recirculating ball-type steering is primarily of parts compositions such as screw rod, steering nut, steering gear housing and multiple circulating balls, circulating ball is placed in the pipeline liquid injecting device between nut and screw rod, sliding friction between playing nut-screw changes the effect of the less rolling friction of resistance into, after the bolt rotary be secured together with wheel steering tubing string gets up, screw rod promotes nut and moves up and down, and nut drives pitman arm back and forth to shake by gear again thus realizes turning to.
As shown in Figure 1, steering nut 12 is core parts of recirculating ball-type steering, and its inside is provided with continuous print screw thread raceway 121, and the end of steering nut screw top raceway is provided with two and goes back to the hole of bead 120, and its middle-end is through is provided with screw rod 122.Go back to the hole of bead 120 particularly important with the relative position degree of screw thread raceway 121, the overproof meeting of position degree causes bolt rotary clamping stagnation, and steel ball rolling is not smooth, thus makes automobile direction hair fastener in the process of moving, there is potential safety hazard.In prior art, the relative position degree returning the hole of bead and screw thread raceway can not detect with general measurer.
Summary of the invention
Technical matters solved by the invention is to provide a kind of steering nut to return the hole of bead and screw thread raceway relative position degree pick-up unit, accurately can detect steering nut and return the hole of bead and screw thread raceway relative position degree, simple to operate, reliable operation.
For solving the problems of the technologies described above, steering nut of the present invention returns the hole of bead and screw thread raceway relative position degree pick-up unit, comprise measurer body, described measurer body left end is fixedly installed left locating piece, middle-end is fixed with right locating piece, right-hand member is equipped with dial gauge by table sandwiched, described measurer body upper surface is fixedly installed backstay along its Width, and measurer body upper surface is also movably set with length bar along its Width by length bar groove; There is location angle bar by Bracket setting above described measurer body, described location angle bar is provided with locating sleeve; Be movably set with survey mass between described left locating piece, right locating piece, the bottom of described survey mass middle-end is provided with locking ball.
After have employed technique scheme, steering nut to be measured is placed on pick-up unit, steering nut lower end is by backstay, length bar location, upper end is located by locating sleeve, survey mass is run through steering nut inner chamber, and screw thread raceway aimed at by locking ball, the hole of bead and screw thread raceway relative position degree can be drawn back from dial gauge reading, Testing index is accurate, simple to operate, reliable operation.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As Fig. 2, Fig. 3, Fig. 4, Fig. 5 are visible, the present embodiment comprises measurer body 1, described measurer body 1 left end is fixedly installed left locating piece 2, middle-end is fixed with right locating piece 3, right-hand member is provided with dial gauge 4 by table folder 40, described measurer body 1 upper surface is fixedly installed backstay 5 along its Width, and measurer body 1 upper surface is also movably set with length bar 6 along its Width by length bar groove; There is location angle bar 7 by Bracket setting above described measurer body 1, described location angle bar 7 is provided with locating sleeve 8; Be movably set with survey mass 9 between described left locating piece 2, right locating piece 3, the bottom of described survey mass 9 middle-end is provided with locking ball 90.
As shown in Figure 2, left locating piece 2 end is to right locating piece 3 end-to-end distance from being L1.Left locating piece 2, right locating piece 3 are provided with end face groove, and groove width is mated with length bar 6.
As shown in Figure 6, the present embodiment carries out calibration by meter calibrating block 11, and meter calibrating block 11 is calibrated bolcks, and it comprises mutually perpendicular stock and quarter butt, and quarter butt left side is also set to L1 to stock end air line distance.Meter calibrating block 11 is loaded between left locating piece 2, right locating piece 3, and its quarter butt left side and left locating piece 2 upper surface groove approach, and now calibrate dial gauge 11, make dial gauge 11 pointer zero set.
As shown in Figure 2, take out meter calibrating block 11, load onto steering nut 12 screw rod 122 not install, steering nut 12 liang of roller seating spaces aim at backstay 5, length bar 6, location angle bar 7 is installed, and plug latch 11 from locating sleeve 8, steering nut 12 is made steadily to be placed on measurer body 1, the passage of survey mass 9 from screw rod 122 is inserted, locking ball 90 is made to aim at the first thread groove of steering nut 12 internal thread raceway, one end of such survey mass 9 makes it and dial gauge 4 head contact, at this moment when dial gauge 4 is shown as zero and the screw thread raceway of steering nut 12 and the position degree that goes back to the hole of bead be qualified, otherwise exceed ± 0.1(drawing tolerance) for defective.
As shown in Figure 2, the distance between latch 11 center line and left locating piece 2 is L2, because latch 11 is corresponding with going back to the hole of bead 120, and the therefore L2 spacing that can think left locating piece 2 and return between the hole of bead 120.
As shown in Figure 4, the distance of locking ball 90 to survey mass 9 end is L3, L3=L1-L2-standard deviation value X, the position deviation in this standard deviation value X and screw thread raceway and time hole of bead, according to the design drawing of steering nut 12, each spot size is fixed, and this standard deviation value X can calculate, and therefore the distance L3 of locking ball 90 to survey mass 9 end is also computable.
It should be noted that, when not relying on meter calibrating block 11 and L3 does not set, those skilled in the art also can directly adopt said method to measure, front and back dial gauge 4 reading difference measured in record, measure L1, L2, L3 length again, according to the length data of dial gauge 4 reading difference, measurement, composition graphs paper size calculates returning the hole of bead and screw thread raceway relative position degree and whether meeting the requirements of tested steering nut.
