Description
Technical field
The utility model relates to a kind of tapper mechanism.
Background technology
Motor is the common device in magnetic valve, and motor shaft is the vitals of motor, and usually, we need to carry out screwing operation on motor shaft.The technique that workpiece makes internal thread is tapping, the main points of tapping technique be screw tap when entering and exit workpiece, the rotation direction of screw tap is contrary.Tapping machine is exactly a kind of lathe with screw tap machining internal thread, and it is most widely used a kind of internal thread machining lathe.By national machinery industry standard, tapping machine series formation is divided into: bench tapping machine--semi-automatic bench tapping machine, vertical tapping machine, Horizontal tap.Because a kind of important classification be most widely used of certain reason excludes wherein, i.e. folding arm tapping machine (hydraulic pressure threading machine, electric threading machine, pneumatic tapper).
In the existing tapping machine of part, all use automatically controlled mode to realize screw tap break-in to change turning to of motor, in the process of workpiece in enormous quantities, common electric machine is rotating so frequently, commutating period is very short again, motor is in startup, reversing braking state substantially, and motor is overcurrent all the time, and heating is serious, common electric machine is difficult to bear, be easy to burn, motor shaft is also very fast tired, easily breaks.Use servomotor to solve the above problems, but the price of servomotor costliness just become another problem.
Utility model content
The utility model is intended to provide a kind of motor shaft tapper mechanism, has the advantages that structure is simple and cheap.
Motor shaft tapper mechanism in this programme, comprise frame, fixing motor, turn round the main shaft being connected in frame, the end of main shaft connects the screw tap being used for tapping by buffer spring, the output shaft of motor and main shaft intersect vertically and are connected with conical friction wheel, main shaft is connected with gear frame, gear frame comprises with conical friction wheel up and down along upper drag ring corresponding respectively and lower drag ring, the spacing of upper drag ring and lower drag ring is greater than the diameter of conical friction wheel, and frame is provided with the shift fork stirred main shaft and move axially.
The feature of technique scheme is: the auto-steering being achieved screw tap by pure mechanical mechanism, shift fork stirs main shaft when moving down, the upper drag ring driving coupling of conical friction wheel and gear frame, motor drives gear frame and main shaft to rotate with a rotation direction, makes screw tap push against workpiece produce tapping pressure by buffer spring.After tapping completes, direction is stirred shift fork and is made main shaft moves, and now conical friction wheel and upper drag ring depart from, and contacts with lower drag ring, and main shaft is with contrary rotation direction action in the process lifted, and screw tap outwards exits workpiece.This programme structure is simple, only employs the auto-associating moved axially between rotation direction that namely limited several part completes main shaft, without the need to extra electric-control system and expensive servomotor, can be applied to the batch tapping manufacturing procedure of motor shaft.
Further, also comprise revolution be connected in frame cam, slide axially the drive link and middle part that are connected in frame and the hinged fork of frame, the wheel of cam is along offseting with one end of drive link, and the slide block on the other end of drive link and fork one end is hinged, and the other end of fork is located at by shift fork.Controlled the motion of main shaft with the rotation of cam by said structure, make operation period more rule can supply, be also very meet periodic law in the characteristics of motion of the situation lower main axis of cam uniform rotation.
Further, be provided with spring between drive link and frame, described spring orders about drive link convergence cam.Make the running of whole mechanism be synchronized with the profile of cam, when cam does not extrude drive link, the action of main shaft is also suitable rule.
Further, main shaft is provided with the convex edge of annular, and shift fork is folded in upper and lower both sides, convex edge.This scheme simple structure is also easy to implement.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: motor 1, conical friction wheel 2, main shaft 3, gear frame 4, upper drag ring 41, lower drag ring 42, cam 5, drive link 6, spring 7, slide block 8, fork 9, shift fork 10, convex edge 11, buffer spring 12, screw tap 13.
Embodiment is substantially as shown in Figure 1: motor 1 is horizontally fixed in frame, and the output shaft level of motor 1 is stretched out by bearings, and it connects conical friction wheel 2.
The main shaft 3 of tapping is vertically slidably connected in frame, and it is namely rotatable also can move axially.Main shaft 3 is connected with gear frame 4 by buffer spring, main shaft and gear frame relative movement excessive time buffer spring can play certain transitional function, the upper and lower side of gear frame 4 is respectively equipped with drag ring 41 and lower drag ring 42, the top of the corresponding conical friction wheel 2 of upper drag ring, the bottom of the corresponding conical friction wheel of lower drag ring, the spacing of upper drag ring and lower drag ring is greater than the diameter of conical friction wheel, and conical friction wheel cannot be contacted with lower drag ring with upper drag ring simultaneously.When conical friction wheel 2 offsets with upper and lower drag ring respectively, the rotation direction of main shaft 3 is contrary.
In frame, passback is connected with cam 5, cam is at the uniform velocity driven by another motor, the lower end of cam 5 and the drive link 6 above it offsets, and drive link is vertically slidably connected in frame and can moves by vertical axial, is provided with spring 7 and pushes against cam 5 with the lower end of ordering about drive link between drive link 6 and frame.The upper end of drive link 6 and the slide block 8 of fork 9 right part hinged, the middle part of fork 9 is articulated with frame, and the left part of fork 9 is connected with shift fork 10, shift fork 10 and convex edge 11 clamping on main shaft 3.Namely the rotation of cam 5 drives main shaft about 3 to move axially by said structure.The lower end of main shaft 3 is operate portions, and it is connected with screw tap 13 by buffer spring 12.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
