Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model tapping machine.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
Please refer to Fig. 1, Fig. 1 is the structural representation of the utility model tapping machine.Tapping machine described in the utility model comprises: electric device 1, housing 23, first gear 11, second gear 12, first turning cylinder 19, the 3rd gear 13, the 4th gear 14, the 5th gear 15, screw mandrel 16, base 17, main shaft 20, slide block 21, some clutch shaft bearings 24, some second bearings 25 and some 3rd bearings 26.
Slide block 21 is provided with bottom described housing 23, described electric device 1 is connected with described housing 23, and described first gear 11, second gear 12, first turning cylinder 19, the 3rd gear 13, the 4th gear 14, the 5th gear 15 are all arranged at described enclosure interior with main shaft 20.
Described first gear 11 is connected with the rotating shaft 2 of described electric device 1, thus described first gear 11 can rotate along with the rotating shaft 2 of described electric device 1.
Described second gear 12 engages with described first gear 11.Described first turning cylinder 19 is through 12 centers of described second gear, and its one end is connected with two clutch shaft bearings 24, and the other end is through the center of described 3rd gear 13.Thus when described first gear 11 rotates, described first gear 11 drives the second gear 12 to rotate, described second gear 12 drives described first turning cylinder 19 to rotate, and the first turning cylinder 19 drives the 3rd gear 13 to rotate again.
Described clutch shaft bearing 24 is preferably ball bearing, and its inner is connected with described first turning cylinder 19, and outer end is connected with described housing 23, to described first turning cylinder 19 fixations.
Described 4th gear 14 engages with described second gear 12, described main shaft 20 is connected with some second bearings 25, and through described 4th gear 14, thus after described 4th gear 14 rotation of described second gear 12 rotation drive, described two or four gear 14 can drive described main shaft 20 to rotate.
One end of described main shaft 20 is provided with tapping-head, and the other end is fixed on described base 17.Its inside is provided with cavity 18, and the inner surface of described cavity 18 is provided with screw thread.
Described 3rd gear 13 engages with described 5th gear 15, described 5th gear 15 is connected with described screw mandrel 16 by two described 3rd bearings 26, described 3rd bearing 26 is ball bearing, and its outer end is connected with described 5th gear 15, and inner and described screw mandrel 16 is connected.Thus when described 3rd gear 13 drives described 5th gear 15 to rotate, described 5th gear 15 drives described screw mandrel 16 to rotate by described 3rd bearing 26.Described screw mandrel 16 1 end and described base 17 are rotationally connected, and the cavity 18 that the other end extends into described main shaft 20 is inner.The outer surface of described screw mandrel 16 is provided with the screw thread matched with the screw thread of described cavity 18 inner surface.
Especially, size and described 5th the not of uniform size of gear 15 of described 4th gear 14 cause, and therefore, described main shaft 20 is inconsistent with the rotating speed of described screw mandrel 16.When described screw mandrel 16 rotates with described main shaft 20, because described screw mandrel 16 exists speed discrepancy with described main shaft 20, therefore described main shaft 20 advances by described cavity 18 along described screw mandrel 16 or retreats.
The bottom of described base 17 is provided with chute, and described slide block 21 matches with the chute of described base 17, is slidably connected on described base 17.
Tapping machine described in the utility model in use, rotating shaft 2 forward or reverse of described electric device 1, described rotating shaft 2 drives described first gear 11 to rotate, described first gear 11 drives described second gear 12 to rotate, and described second gear 12 drives described first turning cylinder 19 and the 4th gear 14 to rotate again.Described first turning cylinder 19 drives described 3rd gear 13 to rotate, and the 3rd gear 13 drives the 5th gear 15 to rotate again.Thus electric device 1 has driven the main shaft 20 be connected with described 4th gear 14 and the screw mandrel 16 be connected with the 5th gear 15 to rotate.Because described 4th gear 14 is different from the diameter of the 5th gear 15, speed difference is there is between described main shaft 20 and screw mandrel 16, therefore described main shaft 20 is by the helicitic texture of its internal cavities 18, advance along described screw mandrel 16 or retreat, and then drive described housing 23 advance along the chute of described base 17 or retreat, tapping machine described in the utility model is rotated by the tapping-head being arranged on described spindle nose and carries out tapping, by the forward and reverse of the rotating shaft 2 of described electric device 1, control described tapping-head advance on the chute direction of described base 17 and retreat, control into silk or move back silk.
Tapping machine structure described in the utility model is simple, and easy to operate, cost is lower.By designing the brand-new kind of drive, achieve the rotary drive only using an electric device just can realize controlling tapping-head, saved cost, overcoming traditional tapping machine needs two electric devices to control the technical problem of tapping-head rotation and tapping-head transmission respectively.
Above-described embodiment of the present utility model is only for the utility model example is described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, other multi-form change and variations can also be made on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to the technical solution of the utility model the apparent change of amplifying out or variation be still in the row of protection domain of the present utility model.
