Abstract
The utility model discloses a ball installation device for an automobile recirculating ball steering gear. The ball installation device is characterized in that a steering nut is installed on a screw, a guide pipe clamp is arranged at the top end of the steering nut, the bottom opening of the guide pipe clamp respectively corresponds to steel ball guide rails arranged on the screw, an upper end opening is arranged at the top end of the guide pipe clamp, the upper end opening corresponds to the bottom opening of a counter pipe and an injection rod which presses steel balls is arranged at the top end of the counter pipe in the vertical direction. Through the arrangement, the utility model overcomes the problems that the recirculating steel balls overflow and the number of the installed recirculating steel balls is wrong in the process of the traditional manual installation of the recirculating steel balls, greatly improves the work efficiency and ensures the assembling quality.
Description
Technical field
The utility model relates to the erecting device of circulation ball in the automobile ball-and-nut steering gear, belongs to the automobile steering device field.
Background technology
The circulation spherical structure is widely used a kind of steering gear version on the automobile at home and abroad at present.Ball-and-nut steering gear generally has the two-stage transmission in (containing mechanical type and hydraulic power formula), and the first order is the bolt and nut transmission, and the second level is rack tooth fan transmission.In the one-level transmission, in the conduit preset holes on the vessel clamp insertion steering nut, form closed type circulation trajectory.
At present, the domestic mode that generally adopts manual installation circulating steel ball only have indivedual enterprises to adopt the digital recognition system assembling, but cost is very expensive, and general producer is difficult to accept.Manual when the circulation ball is installed, earlier with the circulating steel ball of specified quantity through the conduit preset holes, the circulation trajectory of packing into, the vessel clamp and go into the conduit preset holes of again circulating steel ball of volume residual being packed into together with the vessel clamp back-off.Be easy to generate following problem in the practical set process: when circulating steel ball was packed the circulation trajectory into, vessel clamp was not also packed in the conduit preset holes, and the closed circulation trajectory forms as yet, is easy to cause the circulating steel ball track excessive stuck.Quantitatively very easily produce the mistake assembling at circulating steel ball; When the vessel clamp back-off is gone into the conduit preset holes, very easily cause circulating steel ball from vessel clamp, to roll out.Therefore, the mode of tradition assembling circulating steel ball, strong to the dependence of operating personnel's qualification, the phenomenon that Yi Fashengyin error and causing is done over again, efficiency of assembling is low, and assembly quality is difficult to guarantee, is not easy to satisfy the beat of modern production flow process.
Summary of the invention
The utility model purpose is in order to eliminate traditional-handwork existing drawback to be installed, and a kind of ball-loading device of novel, accurate, quick, reliable automobile ball-and-nut steering gear circulating steel ball is provided.
To achieve these goals, steering nut of the present utility model is installed on the screw rod, be provided with a vessel clamp on the top of steering nut, the bottom opening of vessel clamp respectively be located at screw rod on the steel ball guide rail corresponding, top at vessel clamp also is provided with upper end open, this upper end open is corresponding with the bottom opening of counting tube, also is provided with an injection rod by pressing steel balls on the top of counting tube vertical direction.
By above setting, the utility model has overcome at traditional-handwork to be installed in the process of circulating steel ball, and the circulating steel ball track is excessive, quantity mistake dress problem, thereby has improved operating efficiency greatly, and has guaranteed the quality of assembling.
Description of drawings
Now the utility model is described in further detail in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural representation.
Fig. 2 is the vessel clamp structural representation.
Among the figure 1, steering nut 2, screw rod 3, vessel clamp 4, steel ball guide rail 5, upper end open 6, counting tube 7, injection rod 8, conduit follower bolt 9, conduit pressing plate
The specific embodiment
As shown in Figure 1, 2, steering nut 1 of the present utility model is installed on the screw rod 2, be provided with a vessel clamp 3 on the top of steering nut 1, the bottom opening of vessel clamp 3 respectively be located at screw rod 2 on steel ball guide rail 4 corresponding, top at vessel clamp 3 also is provided with upper end open 5, this upper end open 5 is corresponding with the bottom opening of counting tube 6, also is provided with an injection rod 7 by pressing steel balls on the top of counting tube 6 vertical direction.During installation, with the steel ball guide rail 4 on the aligning of the both ends open on the vessel clamp 3 screw rod 2, again the lower nozzle of counting tube 6 is aimed at the upper end open 5 of vessel clamp 3, the circulating steel ball of specified quantity enters from the side opening of counting tube 6, passes steel ball downwards with injection rod 7, and rotating screw bolt 2 matches, steel ball enters in the steel ball guide rail 4 by vessel clamp 3, counting tube 6 is removed, the upper end open 5 of vessel clamp 3 is sealed installation with conduit follower bolt 8, conduit pressing plate 9.
