The structure of above-mentioned auto-manual right-angle head can be divided into three parts substantially.Part I: the multiple blind rivets 23 that arrange on upper box 21 and upper box 21, at right-angle head, in the time that C axle rotates, this part is connected with lathe by multiple blind rivets 23, does not rotate all the time; Part II: lower chain wheel 3, internal gear 61, fluted disc seat 7, upper baffle ring 75, spacer shell 72 and lower baffle ring 76, these parts are fixedly connected to form an entirety; Part III: lower box 22 and the transition disc 9 being fixedly connected with lower box 22, lower box 22 is fixedly connected with by some screws 10 with transition disc 9, forms an entirety.
When realizing automatic right-angle camera function, while needing automatic rotation, tighten after adjustment screw 98, transition disc 9 is blocked firmly to be fixed in the C type groove being surrounded by fluted disc seat 7, spacer shell 72 and lower baffle ring 76, be that transition disc 9, fluted disc seat 7, spacer shell 72 and lower baffle ring 76 are mutually static, that is to say that Part II and Part III do not rotate each other, then first by being installed on the middle bit motion of the pull head oil cylinder on lathe, in the time that the pull head oil cylinder on lathe unclamps certain stroke, first, second and Part III will under Action of Gravity Field, move down certain distance simultaneously, internal gear 61 and external gear 62 engage, rotate by machine tool chief axis again, the external gear 62 that drives taper shank 1 and be threaded with taper shank 1 rotates, external gear 62 drives internal gear 61 to rotate again, and then the rotation of drive Part II and Part III entirety, and Part II and Part III do not rotate each other, thereby realize the rotation of right-angle head main shaft around C axle, the design feature (as 5 ° one point) that the angle that machine tool chief axis rotates around C axle simultaneously need meet upper chain wheel (not shown) and lower chain wheel 3 realizes automatic rotation and the follow-up normal process of determining angle, when normal process, Part II is realized and being fastenedly connected by upper chain wheel and lathe, Part III is tightened by adjustment screw 98, rely on transition disc 9 and lower baffle ring 76, frictional force between transition disc 9 and fluted disc seat 7 realizes and interconnecting, now integrated straight angle head each several part is mutually static, and then realize the machining of part.
When realizing manual right-angle head function, while needing manual fine-tuning to rotate, first by the pull head oil cylinder tension on lathe, lower chain wheel 3 in Part II engages with the upper chain wheel being installed on machine ram, therefore Part II and Part I are all completely fixed on lathe, cannot rotate, manually unclamp again ten adjustment screw 98, because the distance between the upper surface of connecting portion 71 on fluted disc seat 7 and the lower surface of transition disc 9 is than the low 0.2mm of height on spacer shell 72 upper inner platform rank 73, therefore unclamp after ten adjustment screw 98, between the upper surface of the lower surface of fluted disc seat 7 and transition disc 9, there is the gap of 0.2mm, now the frictional force between transition disc 9 and Part II will reduce because of unclamping of adjustment screw 98, can rotate lower box 22 like this, again because the hole penetrating for adjustment screw 98 on transition disc 9 is that corner is the waist-shaped hole 91 of 5 °, therefore Part III can be overall around the center of power transmission shaft 5 Small-angle Rotation within the scope of 0 ~ 5 °, thereby realize manual fine-tuning, when adjusting, first carry out coarse adjustment by the scale on scale 77 and lower baffle ring 76, arrive after required special angle in coarse adjustment, carry out accurate adjustment by examining the means such as rod or laser again, finally lock ten adjustment screw 10, can realize follow-up required special angle processing.And need only ten adjustment screw 10 in tight condition, this right-angle head can any 5 ° one point ground automatic rotation.
Such as need 6.5 °, 36.5 °, 41.5 ° three special of processing, first utilize automatic right-angle camera function to realize the rotation of 5 °, now Part II and Part III rotate simultaneously, then the manual fine-tuning that utilizes manual right-angle head function to realize 1.5 °, now only rotate Part III, can realize special the processing of 6.5 °; After processing, utilize automatic right-angle camera function to realize the rotation of 35 °, do not need manual fine-tuning, can realize special the processing of 36.5 °; In like manner, chain wheel, 40 ° of interlocks, does not need manual fine-tuning, can process again 41.5 ° special.For needing processing work feature, whether the differential seat angle of special can meet the multiple of chain wheel calibration, as met, can process required special by the repeatedly interlock of manual fine-tuning and chain wheel.
