Abstract
The utility model discloses an auxiliary thread rolling frame for improving workpiece coaxiality. The auxiliary thread rolling frame for improving the workpiece coaxiality comprises a stepped shaft parallel to a rotating shaft of a thread rolling wheel, two steps are arranged at each of two ends of the stepped shaft, the diameters of the stepped shaft, inner steps and outer steps are reduced in sequence, a locating plate sleeves each outer step, a fixed plate sleeves each inner step, each locating plate is provided with a locating shaft, and the bottom of each fixed plate is connected with a thread rolling machine body through bolts; one end of each locating shaft is conical while the other end is cylindrical, one locating shaft is fixed with the corresponding locating plate through bolts while the other locating shaft passes through the corresponding locating plate to connect movably, the two locating shafts are coaxial, and the conical pointed ends are opposite to each other. The two locating shafts locate a workpiece based on the axial line of the workpiece to perform thread rolling processing, the coaxiality between the workpiece and threads thereof is guaranteed, and the workpiece load improvement is facilitated.
Description
Technical field
the utility model belongs to field of machining, especially relates to a kind of for improving the rolled thread processing auxiliary frame of workpiece axiality.
Background technology
Screw-rolling machine is workpiece to be carried out to the lathe of the rolling and processing such as screw thread, traditional screw thread rolled thread processing is that workpiece tooth end to be rolled is placed on holder cutter, the other end carries out rolling screw-threads processing by supporting-point or hand rest maintenance level, whether this mode leans on workman's sensation entirely to workpiece level, the axiality of screw thread and workpiece is also the sensation assurance by this level, be difficult to control the coaxial depth of parallelism of workpiece and two thread rolling dies, when workpiece screws in body, not that rotation screws in, but swing, screw in, finally cause the axiality of workpiece and its screw thread poor, and, when the equal machining screw in workpiece two ends, often because can not meeting the demands and cannot install, the axiality at two ends causes scrapping, this bolt is when carrying dynamic loading, consequence is hardly imaginable.
Summary of the invention
In order to overcome traditional offhand rolled thread operation, easily cause workpiece and the poor defect of its thread coaxiality, the utility model aims to provide and a kind ofly guarantees that workpiece rolled thread adds the rolled thread auxiliary frame of man-hour and thread coaxiality.
The technical solution adopted in the utility model is:
A kind of rolled thread auxiliary frame that improves workpiece axiality, comprise a multidiameter with cylindrical die roll shaft parallel, multidiameter two ends respectively arrange two-stage ladder, the diameter of multidiameter, interior ladder, outer ladder reduces successively, on outer ladder, cover has cover on location-plate, interior ladder to have fixed head, described location-plate arranges locating shaft, and fixed head bottom is connected with screw-rolling machine body bolt; One end of locating shaft is that taper, the other end are cylindrical, and locating shaft is fixed with its location-plate bolt, another locating shaft is flexibly connected through its location-plate, and two locating shaft is coaxial and cone point is relative.
According to above-described rolled thread auxiliary frame, described locating shaft axis is parallel with the axis of multidiameter, and described fixed head is that key is connected with interior ladder, and described outer ladder also arranges nut through after location-plate.
Adopt the rolled thread auxiliary frame of the present utility model of above structure, during processing work, locating shaft guarantees the stability of axis of workpiece, difficult swing, excircle of workpiece profile and its screw thread are same benchmark, and screw thread and workpiece axiality are better, have improved the adaptability of workpiece to load environment.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of traditional offhand rolled thread mode of operation;
Fig. 2 is that rolled thread adds man-hour, the position relationship side view of workpiece and thread rolling die;
Fig. 3 is the structural representation of the rolled thread auxiliary frame embodiment of raising workpiece axiality of the present utility model.
The specific embodiment
The description of symbols relating in accompanying drawing: workpiece handheld terminal 11, pad 12, multidiameter 2, fixed head 21, nut 22, workpiece 3, thread rolling die 4, locating shaft 51,52, location-plate 53,54, body 6.
Below in conjunction with accompanying drawing, the technical scheme of rolled thread auxiliary frame of the present utility model is elaborated.
As shown in Figure 1, 2, traditional offhand rolled thread mode, is difficult to control the coaxial depth of parallelism of workpiece and two thread rolling dies, when workpiece screws in body, is not that rotation screws in, but swing, screws in, and finally causes the axiality of workpiece screw thread and workpiece poor.
As shown in Figure 3, improve the rolled thread auxiliary frame of workpiece axiality, comprise a multidiameter 2, ladder, 2 two ends respectively arrange interior ladder, the outer ladder two-stage ladder that diameter reduces successively, and interior ladder passes fixed head 21 and is connected with its key, and outer ladder arranges nut 22 through after location-plate;
Fixed head 21 bottoms are connected with body 6 bolts of screw-rolling machine; Locating shaft 51,52: one end is that taper, the other end are cylindrical, locating shaft 51 is through location-plate 53 and be flexibly connected with it, and locating shaft 52 one end are connected with location-plate 54 bolts, the relative and coaxial line of the cone point of locating shaft 51,52;
Workpiece 3 and locating shaft 51,52 coaxial lines, the axis of workpiece 3, thread rolling die 4 and multidiameter 2 is parallel to each other.
By locating shaft 51,52, workpiece is fixedly made to locating shaft and workpiece coaxial line, when workpiece 3 is added man-hour by thread rolling die 4 rolled thread, workpiece 3 axis are difficult for producing skew, guaranteed that excircle of workpiece profile and its screw thread are same benchmark, improved screw thread and workpiece axiality, be conducive to improve the qualification rate of rolled thread operation and guarantee workpiece load stability.
Claims (4)
1. a rolled thread auxiliary frame that improves workpiece axiality, it is characterized in that: comprise a multidiameter with cylindrical die roll shaft parallel, multidiameter two ends respectively arrange two-stage ladder, the diameter of multidiameter, interior ladder, outer ladder reduces successively, on outer ladder, cover has cover on location-plate, interior ladder to have fixed head, described location-plate arranges locating shaft, and fixed head bottom is connected with screw-rolling machine body bolt; One end of locating shaft is that taper, the other end are cylindrical, and locating shaft is fixed with its location-plate bolt, another locating shaft is flexibly connected through its location-plate, and two locating shaft is coaxial and cone point is relative.
