Further, the backgauge length control device in the aforesaid rotary furrower, wherein: be fixed with bolt on the backgauge sheet, bolt passes behind the connecting rod fastening with nut.
Further, the backgauge length control device in the aforesaid rotary furrower, wherein: in rotating shaft, be provided with the endoporus that can hold regulating shaft vertically.
Further, the backgauge length control device in the aforesaid rotary furrower, wherein: the outside, two ends at gear is respectively arranged with a space collar, and space collar is fixed on the pivoted housing.
The beneficial effect of the utility model is: in rotary furrower, use the described backgauge length control device of the utility model; Through the rotation knob rotating shaft is moved vertically; Thereby can adjust the axial backgauge position of backgauge sheet, realize confirming the purpose of pipe fitting material axial length; Action through control backgauge oil cylinder; Can make rotating shaft drive the rotation of backgauge sheet; Make that the backgauge sheet is positioned at the backgauge position when carrying out backgauge work; Backgauge end-of-job backstop tablet reverse rotation and leave the service aisle of processing and forming parts fully can improve the operating efficiency of processing and forming parts like this; And this backgauge length control device of adjusting backgauge sheet operating position through the control anglec of rotation has also reduced installing space, has satisfied the instructions for use of rotary furrower.
Description of drawings
Fig. 1 is the structural representation of the backgauge length control device in the described rotary furrower of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the backgauge length control device in the described rotary furrower of the utility model is done further detailed explanation.
Referring to shown in Figure 1, the backgauge length control device in the described rotary furrower of the utility model comprises: backgauge sheet 26; Be fixed with bolt 261 on the backgauge sheet 26; It is fastening with nut 27 that bolt 261 passes connecting rod 25 backs, and connecting rod 25 is fixed on an end of rotating shaft 17, is set with pivoted housing 18 in the outside of rotating shaft 17; Be coupled to each other through thin type flat key 23 between rotating shaft 17 and the pivoted housing 18; Make rotating shaft 17 and pivoted housing 18 along the circumferential direction not produce relative rotation but can produce vertically and relatively move that pivoted housing 18 is bearing in pair of bearing 4 and 3 through pair of bearings 6 and 9, on the outer circumference surface of pivoted housing 18, is fixed with gear 7; The transmission that is meshing with each other of tooth bar 8 and gear 7, tooth bar 8 is connected with the piston rod of backgauge oil cylinder 28; The other end in rotating shaft 17 is fastened with thrust ball bearing 15; Adjusting nut cover 14 is bearing on the thrust ball bearing 15; Thrust ring 16 is connected with adjusting nut cover 14 and thrust ball bearing 15 is stuck between thrust ring 16 and the adjusting nut cover 14, and bearing 2 is sleeved on adjusting nut with gap and overlaps 14 outsides, and an end of bearing 2 is fixedly connected with a bearing block 3; Regulating shaft 12 is threaded with adjusting nut cover 14 through its surperficial screw thread; Boss 121 on the regulating shaft 12 withstands on the madial wall of bearing 2 ends, and the outer end of regulating shaft 121 is fixed with knob 1 through key 11, and knob 1 is positioned at the outside of bearing 2; End cap 10 is fixed on the regulating shaft 12 through sunk screw 29, and knob 1 and regulating shaft 12 are fixed.In the present embodiment, in rotating shaft 17, be provided with the endoporus 22 that can hold regulating shaft 12 vertically, regulating shaft 12 can move in endoporus 22 vertically.In the present embodiment, be respectively arranged with a space collar 19 and 20 in the outside, two ends of gear 7, space collar 19 and 20 is fixed on the pivoted housing 18.
The operation principle of the backgauge length control device in the described rotary furrower of the utility model is following: at first described backgauge length control device is installed on the support of rotary furrower.During work; Rotate knob 1 earlier; Knob 1 drives regulating shaft 12 and rotates, and regulating shaft 12 passes through screw drive adjusting nut cover 14 and moves vertically, and adjusting nut cover 14 moves with thrust ring 16 and thrust ball bearing 15 actings in conjunction promotion rotating shaft 17 vertically; The final connecting rod 25 that drives moves with backgauge sheet 26 vertically, realizes the function of the axial backgauge position of adjustment backgauge sheet 26.When needs carry out backgauge work; Make 28 actions of backgauge oil cylinder, backgauge oil cylinder 28 rotates through tooth bar 8 driven gears 7, and gear 7 drives pivoted housing 18 again and and then rotates with rotating shaft 17; Because adjusting nut cover 14 is bearing on the thrust ball bearing 15, thereby adjusting nut cover 14 can and then not rotate; Rotating shaft 17 drives connecting rod 25 and and then rotation of backgauge sheet 26 again, until backgauge sheet 26 is gone to the backgauge position.Behind the backgauge end-of-job; Make backgauge oil cylinder 28 counteragents; Make and then reverse rotation and leave the backgauge position fully of backgauge sheet 26; And leave the service aisle of processing and forming parts fully, the operate as normal that so just can not hinder the processing and forming parts just can improve the operating efficiency of processing and forming parts.
