The specific embodiment
By following description to embodiment; to more help public understanding the utility model; but can't the specific embodiment that the applicant is given be considered as the restriction to technical solutions of the utility model, any definition to parts or technical characterictic change and/or to overall structure do form and immaterial conversion all should be considered as the protection domain that the technical solution of the utility model limits.
Bench drill feed mechanism as shown in Figure 1 to Figure 3, comprise guidance panel 1 in this feed mechanism, buncher assembly 2, gear shaft assembly 3, sleeve 4, Handleset 320, travel switch adjusting part 319, spacer shell 318, clutch shaft bearing 317, jump ring 316, gear shaft 315, adjusting nut 314, gland 313, splined shaft 312, friction plate pad 311, internal toothed friction plate 310, external tooth friction plate 39, friction plate holder 38, scroll spring cover 37, scroll spring 36, scroll spring seat 35, pad 34, bearing holder (housing, cover) 33, the second bearing 32, synchronizing wheel 31, wherein: adjusting nut 314, gland 313, splined shaft 312, friction plate pad 311, internal toothed friction plate 310, external tooth friction plate 39 and friction plate holder 38 consist of friction clutch, splined shaft 312 and synchronizing wheel 31 coaxial sockets, friction plate holder 38 interior chimeric have internal toothed friction plate 310 and external tooth friction plates 39, in the present embodiment, in, the external tooth friction plate respectively has five, the compartment of terrain is entrenched in the friction plate holder 38 successively, be evenly equipped with projection on the external tooth friction plate 39, this projection is corresponding with the groove on friction plate holder 38 sidewalls, in splined shaft 312 passes, external tooth friction plate and friction plate holder 38, fixedly be connected as a single entity by screw with gear shaft 315, have the strip projected parts that conforms to the internal spline shape of internal toothed friction plate 310 on the splined shaft 312, adjusting nut 314 and gland 313 are socketed in respectively on the splined shaft 312, gland 313 prop up on the friction plate holder 38 in, the external tooth friction plate.
The feeding motor is used for driving synchronizing wheel 31, and synchronizing wheel 31 drives friction clutch, and friction clutch female splined shaft 312 rotates.Because splined shaft 312 and gear shaft 315 usefulness screws are together, so gear shaft 315 also rotates thereupon.Satisfy the needs of bench drill auto-feed boring.Degree of tightness by adjusting nut 314, change the pressure between the clutch friction plate, thereby reach effective adjusting of output feeding moment of torsion, rotation adjusting nut 314 promotes gland 313, and then promotion friction plate pad 311 extruding external tooth friction plate 39 and internal toothed friction plates 310, the tightness of nut 314 has determined the size (being the size of moment of torsion) of external tooth friction plate 39 relative internal toothed friction plate 310 frictional force, and the degree of tightness that is to say adjusting nut 314 has determined the size of moment of torsion.External tooth friction plate 39 cooperates formation synchronously with friction plate holder 38, internal toothed friction plate 310 cooperates formation synchronously with splined shaft 312, and holder 38 keeps a rotary freedom with respect to gear shaft 315.Before using this equipment to hole, the frictional force that rotation adjusting nut 314 is regulated between internal toothed friction plates 310 and the external tooth friction plate 39, until sufficient normally drilling workpiece starts the automatic drilling switch of drilling machine, can automatic drilling.Under special circumstances (not sharp such as bit wear), drilling has not been gone down, i.e. original set large of torque ratio, and gear shaft 315 is stuck and can not rotates, and external tooth friction plate 310 is still rotating with external tooth friction bar 39, i.e. inner attrition piece 310 and outside friction disc 39 relative swipings.In the moment of torsion that gear shaft 315 rotates is, frictional force between outside friction disc produces, and inner attrition piece 310 and outside friction disc 39 are middle transition transmission links of moment of torsion in the feed mechanism, transfer of torque is inner, frictional force effect between the outside friction disc, utilize adjusting nut 314, in can regulating, extruding force between the outside friction disc, because the friction between them is directly proportional with the extruding force of adjusting nut, the larger frictional force between them of extruding force is also larger, output torque is also larger, thus the size of feeding moment of torsion with in, the moment of torsion that frictional force between the outside friction disc produces has direct relation.For example to need moment of torsion be 5 Ns/rice to processing work, and the moment of torsion that the frictional force between the inside and outside friction plate produces is less than 5 Ns/rice, and so inside and outside friction plate begins swiping, and gear shaft 315 stops operating, so feeding stops.
Certainly; the utility model can also have other various embodiments; in the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
