Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B place enlarged drawing of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises Rack Body 1, Rack Body 1 is cylindrical, three roll parts 2 are installed in the Rack Body 1, the axis of three roll parts 2 consists of equilateral triangle, the roll 201 of three roll parts 2 consists of the pass 3 of rolled steel tube, three roll parts 2 rotatably are installed on the slide block 4 by bearing respectively, slide block 4 is slidingly mounted in the Rack Body 1, slide block 4 can along the radially sliding of pass 3, in the present embodiment, be provided with the guide rail 5 that radially arranges along pass 3 in the Rack Body 1, slide block 4 slides along guide rail 5, guarantees the accuracy that slide block 4 slides.Slide block 4 is provided with the inclined-plane, and three voussoirs 6 are movably arranged in the Rack Body 1, and the inclined-plane of each voussoir 6 cooperates with the inclined-plane contact of corresponding slide block 4.One side of Rack Body 1 is provided with inner cap 101 and enclosing cover 102, ring gear 7 rotatably is installed between the inner cap 101 and enclosing cover 102 of Rack Body 1 one sides, ring gear 7 is coaxial with pass 3, three swivel nuts 8 voussoir 6 that is threaded respectively, rotary threaded sleeve 8 can make voussoir 6 move back and forth up and down (such as Fig. 2), swivel nut 8 is cup-shaped, and the flange 801 of swivel nut 8 is spacing by inner cap 101, and swivel nut 8 only can rotate and can not do axially-movable.Three drive rods 9 are sleeved in the swivel nut 8, drive rod 9 connects swivel nut 8(such as Fig. 3 by spline 902), pinion 10 connects drive rod 9 by spline 902, pinion 10 and ring gear 7 engagements, spring 11 is between the boss of the bottom surface that is contained in swivel nut 8 and drive rod 9, rotate any drive rod 9 and can drive pinion 10 rotations, and rotate synchronously by ring gear 7 other two pinions 10 of drive, thereby band movable snail sleeve 8 rotates synchronously.The outer end of drive rod 9 is provided with square toes 901, conveniently utilizes tool operation drive rod 9.
When the roll gap of the roll 201 of adjusting three roll parts 2, with any one in three drive rods 9 of spanner rotation, drive rod 9 band movable snail sleeves 8 and pinion 10 rotate, driving voussoir 6 by swivel nut 8 moves, moved radially by the effect driving slide block 4 of voussoir 6 by the inclined-plane, thereby the roll 201 that drives roll parts 2 moves radially; Because three pinions 10 mesh with ring gear 7, driving ring gear 7 by a pinion 10 rotates, ring gear 7 drives two other pinion 10 and rotates synchronously, thereby make two other swivel nut 8 drive voussoir 6 and slide block 4 synchronizing movings, thereby the roll 201 that drives three roll parts 2 moves radially synchronously, thereby reach the purpose of the roll gap of the roll 201 of adjusting three roll parts 2, make the center of the circle that the arc surface of the roll 201 of three roll parts 2 forms consistent with the center of rolled steel tube.
