Abstract
The invention discloses an intelligent electric tightening machine of shaft head nuts. The invention is mainly formed by respectively fixedly connecting a master driver (12) and a secondary driver (18) to the inner cavity of a machine frame (6), the output shaft of the secondary driver (18) is fixedly connected with a drive gear (17) which is matched and connected with a driven gear (11) which is rotatablely disposed on the output shaft of the master driver (12), and the driven gear (11) is in fixing connection with a rotary arm (4) which is connected with a pivoted arm spanning sleeve. The end portion of the output shaft of the master driver (12) is connected with a spanning sleeve of the shaft head nuts (1), and the circuits of the master driver (12) and the secondary driver (18) are respectively connected with the circuit of a control cabinet (9). In operating time, the secondary driver actuates the pivoted arm spanning sleeve to toggle a wheel boss to uniformly rotate, thereby realizing that the end surface of a bearing which is connected to the wheel boss bears even force and can not be deformed in the process of tightening the shaft head nuts, reducing the abrasion of the bearing in the practical using course, and obviously improving the service life of the invention.
Description
(1) technical field: the present invention relates to the nut screwing clamping device; Be specifically related to a kind of intelligent electric screwing down machine for spindle nose screwed cap.
(2) background technology: the wheel hub that connects is installed at automotive axle axle two ends in the prior art, is by axis head nut it to be tightened, and normally wheel hub is motionless, and tightening machine is only rotated axis head nut and tightened.Exist not enough: because tightening machine is in the process that the drive axis head nut is tightened wheel hub gradually, be connected in the bearing circumferential end surfaces in the wheel hub mesopore, usually be subjected to the axis head nut end face to tighten extruding unbalance stress and being out of shape, aggravate hub bearing wearing and tearing in actual use, reduced its service life.
(3) summary of the invention: the deficiency at above-mentioned prior art exists, the objective of the invention is to, a kind of minimizing bearing wear is provided, improve the intelligent electric screwing down machine for spindle nose screwed cap in its service life.
For achieving the above object, technical scheme of the present invention is achieved in that this intelligent electric screwing down machine for spindle nose screwed cap, mainly comprises frame and switch board; Its improvement is: at described frame inner chamber, be fixed with master driver and secondary driver respectively; The driving gear that is connected on the described secondary driver output shaft joins with the driven gear engagement that rotation is connected on the master driver output shaft; Described driven gear and pivoted arm are connected; Be connected with pivoted arm on the described pivoted arm and pull cover; Described master driver output shaft end is connected with axis head nut and pulls cover; The circuit of described master driver and secondary driver joins with the switch board circuit respectively.
The present invention takes said structure, during work, pulling cover by secondary driver drives pivoted arm stirs wheel hub and does average rate and rotate, the bearing face stressed even extruding in the axis head nut rundown process that has realized being connected on the wheel hub is indeformable, reduce bearing wearing and tearing in actual use, obviously improved its service life.
(4) description of drawings: Fig. 1 is a front view of the present invention;
Fig. 2 is a tightening machine power set top plan view among Fig. 1;
Fig. 3 is a tightening machine power set left view among Fig. 1.
(5) specific embodiment: Fig. 1-shown in Figure 3.This intelligent electric screwing down machine for spindle nose screwed cap mainly comprises frame 6 and switch board 9; At described frame 6 inner chambers, be fixed with master driver 12 and secondary driver 18 respectively; The driving gear 17 that is connected on described secondary driver 18 output shafts joins with driven gear 11 engagements that rotation is connected on master driver 12 output shafts; Described driven gear 11 is connected with pivoted arm 4.Symmetry is connected with 2 pivoted arms and pulls cover on the described pivoted arm 4; Described pivoted arm is pulled cover, and its structure is at sleeve 14 inner chambers that are fixed on the pivoted arm 4, is provided with back-moving spring 15 and slip sleeve-board 13 (shown in Figure 2).Described master driver 12 output shaft ends are connected with axis head nut and pull cover 1.The circuit of described master driver 12 and secondary driver 18 is respectively with switch board 9 circuit join (Fig. 1, shown in Figure 2).During work, the operator holds handle 8, by 5 liftings of direction switch 7 control connection axles, so that adjust the height and position that hub nut connects, two pivoted arms on the pivoted arm 4 are pulled on the nut that the collar is enclosed within wheel hub, the axis head nut that master driver 12 output shaft ends are connected with is pulled cover 1 ring set on axle shaft axis head nut to be tightened simultaneously, start main, secondary driver motor switch 16, master driver 12 drove spindle noses and pulled 1 pair of axis head nut of cover and begin to tighten this moment, the driving gear 17 of secondary driver 18 by being connected on the output shaft, drive driven gear 11 and pivoted arm 4 rotations, and pull cover by pivoted arm and stir the spindle nose sleeve-board 1 rotation direction reversed slow rotation of wheel hub along master driver 12 output shafts, when axis head nut is tightened the torque value that reaches certain, torque sensor by master driver 12 sends signal, and switch board 9 is promptly controlled main, secondary driver motor quits work.Thereafter switch board 9 sends signal once more, and the motor backward rotation certain angle of control master driver 12 stops, so that the best effort gap of the taper roll bearing rotational engagement that adjustment wheel hub mesopore is connected with.Realized axis head nut in rundown process, the active force extruding that acts on the hub bearing end face is evenly indeformable, and hub bearing rotates light and flexible, long service life.
The above only is a preferred implementation of the present invention.Be noted that for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention; need not other technical characterictic that the process creative work just can be associated; can also make some modification or improvement; these variations obviously all should be considered as equivalent feature, all belong within the protection domain of patent of the present invention.
