Detailed description of the invention
Now in conjunction with the embodiments, the invention will be further described for accompanying drawing:
As shown in Figure 1, three-jaw aperture chi maintenance frock comprise tool pedestal 1, around the shaft 2, gear wheel 3, pinion 4, differential sleeve coenosarc cover the 5, first screw 6, little pivot pin 7, circular arc pressing plate 8, circular arc pressing plate 8, second screw 9, housing screw 10, handle 19 and jump ring 20, the relative both sides of tool pedestal 1 are provided with symmetrical equal-sized hole, 2 be arranged in tool pedestal 1 two side holes around the shaft, one end is provided with handle 19, the other end uses jump ring 20 to fix, gear wheel 3 is fixed on around the shaft on 2, and engage with pinion 4, overlapping 5 with the differential sleeve coenosarc of pinion 4 coenosarc uses the first screw 6 to be fixed on the differential sleeve of three-jaw aperture chi, a semicircular opening groove is provided with below the hole of the tool pedestal 1 that those one end that 2 use jump rings 20 are fixing are around the shaft corresponding, the diameter of semicircular opening groove is greater than the diameter at chi neck place, three-jaw aperture, semicircular opening groove is concentric with pinion 4, opening part around semicircular opening groove is provided with circular arc pressing plate 8, one end of circular arc pressing plate 8 is arranged in tool pedestal 1 with little pivot pin 7, the other end and centre position are provided with screw, when in running order, pinion 4 is enclosed within the differential sleeve of three-jaw aperture chi, the neck place of three-jaw aperture chi puts in the semicircular opening groove of tool pedestal 1, circular arc pressing plate 8 is used to cover, use the second screw 9 to fix at the other end of circular arc pressing plate 8, the centre position of circular arc pressing plate 8 uses housing screw 10 to fix.
As shown in Figure 2, also comprise pressurization ring body 11, set bolt 12, adjusting bolt 13, lower pressing spring 14 and suppress pin 15, when in running order, the pedestal head 18 that pressurization ring body 11 is enclosed within three-jaw aperture chi use set bolt 12 to tighten up, on pressurization ring body 11, the position corresponding with gauge head is provided with and suppresses pin 15, suppress pin 15 top and be provided with lower pressing spring 14, the other end of lower pressing spring 14 contacts with adjusting bolt 13.
Installation process: be first coated with M10 abrasive pastes on conical rod head 16, again three-jaw aperture chi differential sleeve is inserted in the collar aperture with pinion 4 coenosarc, fix with the first screw 6, second screw 9 is fastening by arc pressuring plate, rotatably compress screw 10 and push down three-jaw aperture chi, three-jaw aperture chi is firmly fastened in tool pedestal 1, as shown in Figure 3.Then pressurization ring body 11 is enclosed within three-jaw aperture chi pedestal head 18, is fixed tightly on pedestal head 18 by three set bolts 12 one-tenth 120 ° are uniform.Afterburning to about 10N-12N by moment spiral shell cutter knob adjusting bolt, the power of three bolts wants consistent, as shown in Figure 4.
