Abstract
The utility model relates to a non-stopping automatic tapper which is composed of a casing, a motor, a coupling spindle, a transmission clutch mechanism, etc., wherein, in the transmission clutch mechanism, an upper gear on the coupling spindle and an upper counter gear which is engaged with the upper gear drive a lower counter gear by a driven shaft and drive a lower gear by a gear idle, the lower gear drives a lower shaft sleeve, a shaft coupling is arranged in a main shaft, and the upper and the lower matching surfaces of the shaft coupling and the coupling spindle are matched with the lower shaft sleeve to form that clutch. The utility model taps when pressing downwards and withdraws when lifting upwards without stopping the machine. The utility model has the characteristics of small volume, simple operation, high efficiency, enhancing the lifetime of the tap, etc.
Description
The utility model relates to tapping machine, is specially adapted to (steel part is below 8 millimeters) below 12 millimeters tapping.
Existing tapping machine after having attacked screw thread, withdraws from screw tap again, and this screw tap that withdraws from adopts two-direction switch, because motor is bad easily along frequent operation.Especially process the screw thread of blind hole, be difficult for more grasping.
The purpose of this utility model needn't be shut down, as long as up carry the tapping machine that will withdraw from automatically after to be that design is a kind of attacked screw thread.
The technical scheme that the utility model is not shut down automatic tapping machine is: be made up of institutes such as housing, motor (power), coupling spindle and transmission clutches; so-called transmission clutch is cogging on coupling spindle; last pinion with the engagement that cogs; drive pinion down by driven axle; following pinion drives lower gear by carrier gear; lower gear drives Lower shaft sleeve, and shaft coupling is installed in the main shaft, and the upper and lower mating surface of shaft coupling matches with coupling spindle and Lower shaft sleeve.
The automatic tapping machine of not shutting down of the present utility model, the axial angle α of the last mating surface of its shaft coupling and following mating surface is 8 °~14 °; The best is 10 °~11 °.
The automatic tapping machine of not shutting down of the present utility model, its shaft coupling is that nonmetallic materials are made, as making with materials such as phenolic aldehyde polyester folder cloth or fiberglass.
The automatic tapping machine of not shutting down of the present utility model, mounting plane bearing between housing and coupling spindle and Lower shaft sleeve.
Need not shut down when the utility model discloses a kind of work, in rotating continuously, finish the automatic tapping machine of attacking and moving back, just as using drilling machine; and can be installed on the bench drill and use, compared with the prior art, it is little to have a volume; the efficient height, simple to operate, when attacking to pressing down; up carry when moving back; needn't shut down, particularly attack the screw of blind hole, after attacking the requirement of the scale degree of depth; upwards carry and to withdraw from, and improve screw tap service life.
Fig. 1 is that the utility model is not shut down the automatic tapping machine structural representation.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing 1.
The utility model has related to a kind of automatic tapping machine, a housing 6 is arranged, housing links to each other with coupling spindle 1 by bearing 5, available baffle plate 3 and fixing jump ring 2, coupling spindle 1 connects power, as motor, coupling spindle is installed gear 7 or is made one with cogging, cog and last pinion 17 engagements, drive pinion 14 down by driven axle 19 again, following pinion drives lower gear 11 by carrier gear 13, and lower gear is installed on the Lower shaft sleeve 12 or makes one with Lower shaft sleeve, between Lower shaft sleeve 12 and coupling spindle 1 and the main shaft 21 bearing 22 is arranged, 20, shaft coupling 8 is installed on the main shaft, and hold-doun nut 4 and pad 9, the outer wall of shaft coupling have last mating surface 16 and following mating surface 15 up and down, coupling spindle 1 presses down when work, whole tapper mechanism moves downward, and the screw tap that main shaft 21 drives is attacked workpiece with quilt and collided, and pushes up on the main shaft, be that mating surface 16 cooperates (promptly forming clutch) on the shaft coupling on the main shaft 21 with coupling spindle 1, carry out the tapping action.After having attacked screw, whole tapper mechanism is up carried, and under the deadweight effects such as main shaft 21 and screw tap, mating surface 16 breaks away from coupling spindle 1 on the shaft coupling, and mating surface 15 cooperates with Lower shaft sleeve 12 under the shaft coupling, because carrier gear 13 is arranged, Lower shaft sleeve 12 rotation directions are opposite with coupling spindle 1, therefore, very rewind down goes out screw tap.Withdraw from load in order to alleviate, mounting plane bearing 10,18.For the clutch that shaft coupling 8 and coupling spindle 1 and Lower shaft sleeve 12 are formed has frictional force preferably, reliable operation, thereby shaft coupling 8 is made by macromolecule phenolic aldehyde polyester folder cloth or fiberglass one class material, and the axial angle α of upper and lower mating surface 16,15 is 8 °~14 °, and the best is 10 °~11 °.Housing 6 can adopt polyformaldehyde or aluminium or other material to make.
