Abstract
The utility model relates to an all-purpose measuring instrument which is used to measure the helical pitch of the steering nut of the circulation ball diverter and the parameter like the conduit hole toward the central position degree of the screw-shaped rolling track, composed by an electric part and a mechanical part. The electric part comprises a computer, a printer, a digital indicator, an interface circuit and a simultaneously induct ruler; the mechanical part comprises a support seat, a measured nut clamp, a horizontally moving mopping board and a feeler pin. The instrument has the advantages of reasonable structure, reliable operation, convenient use and high measuring accuracy, and can be applied to measure the finished product and the half-finished product of the steering nut of the circulation ball diverter and to measure a variety of nuts of the ball guide screw.
Description
A kind of pitch (4 or 2) that is used to measure the ball-and-nut steering gear steering nut, guide hole are the measurement mechanisms that application machine and electric approach are integrated as feature with respect to the isoparametric general measuring instrument of position degree at nut inner thread raceway center.
Recirculating ball-type steering belongs to automotive security spare, steering nut dimensional accuracy height in the steering gear directly influences the performance and the life-span of steering assembly, therefore to the processing of steering nut, accuracy requirement is higher, and particularly the pitch of nut and guide hole are particularly important with respect to the position degree at screw thread raceway center.Past adopts two cover mechanical type cubings all to measure 4 guide holes simultaneously respectively with respect to the position degree of tooth bar and the screw thread raceway positional precision to tooth bar with tooth bar location (tooth bar on the nut) for the measurement of steering nut, then through converting, draw the positional precision of guide hole at last with respect to screw thread raceway center, this indirect type measuring method troublesome poeration, cumulative errors is big, and measuring accuracy is low.Recently U.S. TRW Ltd. (US) One Space Park, Redondo Beach CA 90278 U.S.A. newly develops a kind of steering nut measuring instrument that microcomputer technology adopts single seat mapping metering method of using.This measuring instrument has only solved the measurement to nut pitch, still can't solve the problems of measurement at guide hole phase double thread raceway center.Provide a kind of positional precision and the isoparametric general measuring instrument of nut spiral shell square that can directly measure the guide hole phase double thread raceway of steering nut at the problems referred to above the utility model, it is by means of microcomputer technology, employing can be at x, the planker that y two coordinate directions move, drive special measuring head, be equipped with that corresponding software programs realizes.
The concrete structure of this measuring instrument will be described in detail in conjunction with the following drawings.
Fig. 1, the structural representation of steering nut general measuring instrument.
Fig. 2, the gauge head vertical view of steering nut general measuring instrument.
Fig. 3, the steering nut top plan view.
Fig. 4, the steering nut vertical view.
As shown in the figure, this instrument is made up of electric and mechanical two parts. Electric part comprises computer 1, printer 2, digital display meter 3, interface circuit 4, synchronously induction ruler 5 compositions such as grade; Mechanical part is by bearing 6, tested nut clamp 7, and transverse shifting planker 8 vertically moves planker 9 and gauge head 10 forms.
Gauge head 10 consists of one by steel ball contact 11 and the inserted link 12 that can horizontally rotate 180 °, and is fixed on and vertically moves on the planker 9, vertically move simultaneously planker 9 and be located on the transverse shifting planker 8, and bearing 6 produces and mutually moves both vertically relatively.
This instrument is provided with two synchronous induction ruler of cover and corresponding with it digital display meters.The synchronous induction ruler of two covers is located at respectively and vertically moves planker 9 with laterally between moving carriage 8 and the bearing 6, respectively induced lateral moving carriage 8 along the shift value of x direction with vertically move the shift value of planker 9 along the y direction.
The measuring principle of this instrument:
This instrument is used to measure the steering nut of ball-and-nut steering gear, shown in Fig. 3,4.Load onto tested nut, mobile gauge head 10 in steel ball contact 11 incision screw thread raceways, is measured (1)～coordinate values of (6) point successively, and each coordinate values just draws the pitch value of nut through Computing; Flip horizontal steel ball contact 11 then, measure (7) successively, (8), (9) three raceway coordinate values, according to the addition of corresponding point coordinate values divided by 2 computing, obtain the virtual center value of nut rolling way, utilize inserted link 12 to measure 4 hole coordinate values of (10) above the nut～(13) point successively again, because the rotation center of rotation steel ball contact 11 and the relative position of inserted link 12 are the (see figure 2)s of fixing, therefore, by after the coordinate conversion again and the nut rolling way virtual center value that records relatively can obtain distance value between nut thread raceway center and 4 guide holes.Whether measured value is with can to differentiate tested each grade of nut size after each theoretical value (drawing required value) is compared qualified.Above-mentioned computing, comparison, differentiation are finished automatically by computing machine, and can show simultaneously, print its measurement result.According to above principle, this instrument also can be measured the exact position of the relative tooth bar of guide hole and the position of the relative tooth bar of screw thread raceway or the like parameter.
The utility model is rational in infrastructure, and reliable operation is easy to use, all can measure the finished product and the semi-manufacture of nut.
This instrument not only can be used for measuring various steering nuts, also can be used for measuring the nut of various ball screws.
Most preferred embodiment of the present utility model, bearing 6 and horizontal moving carriage 8 and vertically move and all adopt spherical guide mechanism between the planker 9.
