Description
Technical field
The utility model belongs to field of machining, relates to a kind of threading apparatus, relates in particular to a kind of for the tapping range controlling mechanism on the threading apparatus.
Background technology
At present, domestic threading apparatus commonly used, dual mode is adopted in the control of its tapping stroke substantially: a kind of is to adopt manual mode, owing to manually have some uncertain factors in the control, so the control to the tapping stroke does not often reach desirable effect, because manually control inaccurately, and it is shallow or excessively dark to cause tapping depth to cross, cause scrapping of work piece, the damage of threading tool; Another is to adopt automatic mode, drives block and depress contact switch in the process of tapping axis feeding, then signals to machine tool control system by contact switch, and then controls the stroke of tapping by control system.Depress for several times because this kind contact switch will be knocked in each working cycles of lathe, so it is more fragile, in the situation of field of machining batch production, just embody its inadaptability.So, in order to ensure the stability of threading apparatus in the machining batch production, avoid occurring in use unreliable of some element in the inaccurate and tapping travel control device of tapping stroke, research and develop a kind of compact conformation, the tapping range controlling mechanism that is used on the threading apparatus of dependable performance is fully necessary.
The utility model content
The purpose of this utility model is to provide a kind of compact conformation, dependable performance be used for tapping range controlling mechanism on the threading apparatus.
The technical solution of the utility model is: be used for the tapping range controlling mechanism on the threading apparatus, comprise: tapping main spindle box body 1, left hex nut 2, signal shaft 3, worm gear 4, tapping worm screw main shaft 5, support set 6, switch bracket 7, contactless proximity switch 8, contactless proximity switch 9, contactless proximity switch 10, protective cover 11, right hex nut 12, right signal piece 13, left signal piece 14; It is characterized in that: support set 6 is sleeved on the tapping main spindle box body 1, and signal shaft 3 inserts in the support set 6, and the one end enters in the tapping main spindle box body 1, and worm gear 4 is installed, and screws with left hex nut 2; Signal shaft 6 other ends enter in the protective cover 11, are set with successively left signal piece 14, right signal piece 13, screw with right hex nut 12.
The tapping main spindle box body is equipped with switch bracket 7 on the 1 outside below, and contactless proximity switch 8, contactless proximity switch 9, contactless proximity switch 10 are installed on the switch bracket 7 successively.
Worm gear 4 bottoms in the tapping main spindle box body 1 are equipped with tapping worm screw main shaft 5.
Protective cover 11 is installed in tapping main spindle box body 1 right flank.
The utility model can reach following beneficial effect after adopting technique scheme: this mechanism compact conformation, and dependable performance guarantees that the tapping stroke satisfies the product size requirement, failure rate is low has fully guaranteed the stability that threading apparatus is processed.This tapping controlling organization can be applicable on the tapper of various batch productions, can finish efficiently, reliably the needs of all kinds of part tapping processing.
Description of drawings
Fig. 1 is the structure cross-sectional schematic that the utility model is used for the tapping range controlling mechanism on the threading apparatus.
Fig. 2 is the side direction structural representation that the utility model is used for the tapping range controlling mechanism on the threading apparatus.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.Shown in accompanying drawing 1 ~ accompanying drawing 2: the main parts size that can be used for the novel tapping range controlling mechanism of batch machining is: tapping main spindle box body 1, left hex nut 2, signal shaft 3, worm gear 4, tapping worm screw main shaft 5, support set 6, switch bracket 7, contactless proximity switch 8, contactless proximity switch 9, contactless proximity switch 10, protective cover 11, right hex nut 12, right signal piece 13, left signal piece 14.Support set 6 is sleeved on the tapping main spindle box body 1, and signal shaft 3 inserts in the support set 6, and signal shaft 3 one ends are set with worm gear 4, left hex nut 2 and worm gear 4 are locked on the left shaft shoulder of signal shaft 3, and worm gear 4 bottoms are equipped with tapping worm screw main shaft 5; Signal shaft 3 other ends are installed left signal piece 14, right signal piece 13, right hex nut 12 successively; Right hex nut 12 is locked at right signal piece 13, left signal piece 14 on the right shaft shoulder of signal shaft 3, switch bracket 7 is installed on the tapping main spindle box body 1, contactless proximity switch 8, contactless proximity switch 9, contactless proximity switch 10 are installed on the switch bracket 7, tapping worm screw main shaft 5 is installed on the tapping main spindle box body 1, and protective cover 11 is installed on the tapping main spindle box body 1.
Threading apparatus carries out tapping and adds man-hour, 5 rotations of tapping worm screw main shaft, drive worm gear 4 rotations, worm gear 4 drives signal shaft 3 rotations, and signal shaft 3 drives 13 rotations of right signal piece, as shown in Figure 2, signal shaft 3 drives right signal piece 13 and is rotated counterclockwise shown position, right signal piece 13 and contactless proximity switch 10(control reverse signal) produce induction, contactless proximity switch 10 signals to control system, shows that tapping this moment stroke puts in place.On the control system control tapping this moment worm screw main shaft 5(main shaft threading tool is installed) stop the rotation and advance, make simultaneously on the tapping worm screw main shaft 5(main shaft threading tool be installed) begin to counter-rotate and return, worm screw main shaft 5 drives worm gear 4 rotations, worm gear 4 drives signal shaft 3 rotations, signal shaft 3 drives 14 rotations of left signal piece, as shown in Figure 2.When signal shaft 3 turns clockwise the α angle, left signal piece 14 and contactless proximity switch 8(control signals in situ) produce and respond to, show that this moment, threading tool was return original position, on the control system control tapping this moment worm screw main shaft 5(main shaft threading tool is installed) stop the rotation and retreat, at this moment the fabrication cycles of a tapping just is through with.When contactless proximity switch 10(control reverse signal) and contactless proximity switch 8(control signals in situ); because certain reason is not normally sent in the situation of signal; signal shaft 3 can continue rotation with block 13 or 14; when it rotates to contactless proximity switch 9(interlocking signal) the position time; contactless proximity switch 9 can send an interlocking signal to control system; tapping worm screw main shaft 5 is stopped by force; whole threading apparatus produced a protective effect; avoid occuring misoperation, cause unnecessary loss.This kind tapping range controlling mechanism so that the stability of threading apparatus and reliability have obtained very large reinforcement, can satisfy the needs of batch machining on the various machining production lines fully.
