Description
Technical field
The utility model belongs to a kind of nut changer.Be mainly used in riding of dismounting vehicle latch plate and climb nut.
Background technology
Traditional nut changer design is unreasonable, uses inconvenient.It uses motor as power, motor gear drives duplicate gear, duplicate gear drives big or small clutch gear again, when overcoming removing nut, produce huge torsional forces and pause and cause motor load overweight and burn motor, on big or small clutch gear group, also must be provided with pressure buffer axle and relevant complicated buffer spring structure.However, the spoilage of motor and each element of body is also high, and on the other hand, traditional nut changer is subjected to the constraint of electricity big, and no electricity can not be worked, and the torsional forces of motor is less, often can not tighten or back out nut.Simultaneously wheel body is fixed, no elevating function, and elbow and pass the energy tube wall and can not turn to, causing can not dismounting to top nut, and it is big also to have an elbow volume, and the guide pin bushing cushion effect is little, the shortcoming of result of use difference.
Summary of the invention
The purpose of this utility model is a kind of nut changer of design, makes it have powerful, and torsional forces is big, can flexible modulation the elbow direction, simple in structure and cost is low, do not have electricity operation and easy to use effective, prolonged anti-advantage.For this reason, power of the present utility model is the wind big gun, the wind emplacement is on the wind gun carriage of body rear end, the square head of wind big gun power transmission shaft front end can be inserted, or pull away in the interior square head axial trough of splined shaft, splined shaft is positioned at body, its two ends are coupling by bearing and body, be fixed with driving gear on the splined shaft, the big driven duplicate gear of driving gear toe joint, the little driven duplicate gear of big driven duplicate gear toe joint, little driven duplicate gear toe joint driven gear, driven gear is fixed on the interior long splined shaft of body, the middle rear end and the body of long splined shaft are coupling, the cone pinion that its front end passes in hub splines and the elbow is fixed as one, cone pinion toe joint large bevel gear, large bevel gear and little key axle lower end fuse, the little key pivot pin of little key axle upper end is positioned at the flat groove of double-layer bumper guide pin bushing lower end, is provided with the swivel nut pin of swivel nut lower end in the flat groove of double-layer bumper guide pin bushing upper end, and an end of hub splines is provided with steering knuckle, the other end is an elbow, body is positioned on the vehicle seat, and the vehicle seat lower end is provided with the movable carriage that is made of lower carriage on two groups, is coupling with hold-down nut between the corresponding last lower carriage, be bolted with screw rod in two hold-down nuts, screw rod one end is provided with shaking tray.
The utility model has the advantages that to have powerful, torsional forces is big, can flexible modulation the elbow direction, simple in structure and cost is low, do not have electricity operation and easy to use effective, prolonged anti-advantage.
Description of drawings
Fig. 1, be structural representation of the present utility model.
Specific embodiments
As shown in Figure 1, the power of nut changer is the wind big gun, and the product of selling on the wind big gun yarn market drives the pneumatic tool that air compressor rotates wind big gun power transmission shaft 8 by motor or engine.The wind emplacement is on the wind gun carriage 11 of body rear end, and fixedly the wind big gun is on the wind gun carriage in the wind big gun body 9 insertion wind big gun body fixing holes 10 and by standing screw 5, and standing screw 5 upper ends are provided with twists 16, fixes in order to convenient.The square head 7 of wind big gun power transmission shaft front end can be inserted, or pull away in the square head axial trough 2 in the splined shaft 3, splined shaft is positioned at body 1, its two ends are coupling by bearing 39 and body, be fixed with driving gear 4 on the splined shaft, the big driven duplicate gear 12 of driving gear toe joint, the little driven duplicate gear 13 of big driven duplicate gear toe joint, little driven duplicate gear toe joint driven gear 25, driven gear is fixed on the long splined shaft 28 in the body, and making the rotating speed of long splined shaft through the deceleration of big or small driven duplicate gear like this is about 50～55 commentaries on classics of per minute.The two ends of the driven duplicate gear of size all are coupling with corresponding body by bearing.The middle rear end of long splined shaft is coupling by bearing and body, the cone pinion 30 that its front end passes in hub splines 29 and the elbow 35 is fixed as one, cone pinion is toe joint large bevel gear 32 in elbow 35, large bevel gear and little key axle 31 lower ends fuse, the little key pivot pin 33 of little key axle upper end is positioned at the flat groove 34 of double-layer bumper guide pin bushing 38 lower ends, be provided with the swivel nut pin 36 of swivel nut 37 lower ends in the flat groove of double-layer bumper guide pin bushing upper end, one end of hub splines (or claiming to pass the energy tube wall) is provided with steering knuckle 26, the other end is an elbow, steering knuckle fuses with body by regulating bolt 27, like this, steering knuckle and body are by the adjusting bolting, or separation.Unload the adjusting bolt, Rotating bend and hub splines make downward or other position of swivel nut, the adjusting bolt of screwing on again, the nut of dismantled and assembled any direction then.
Body is positioned on the vehicle seat 15, the vehicle seat rear end is provided with vehicle seat handrail 14, the vehicle seat lower end is coupling and is provided with the movable carriage that is made of two groups of upper brackets 24 and lower carriage 19, be coupling with hold-down nut 18 between the corresponding last lower carriage, be bolted with screw rod 20 in two hold-down nuts, screw rod one end is provided with shaking tray 17, which is provided with crank 16.Wheel carrier 23 is coupling by support shaft 21 and lower carriage, and wheel carrier is provided with wheel 22, is used to transport body.The rotation crank makes screw rod drive two hold-down nuts and draws close mutually, or separately can regulate height of the carbody.
During use, the wind big gun is fixed on the wind big gun fixed mount, start the wind big gun, wind big gun power transmission shaft 8 rotates, and then the driving gear on the drive splined shaft, driving gear drives big driven duplicate gear, and big driven duplicate gear drives little driven duplicate gear, and little driven duplicate gear drives driven gear, the long splined shaft of driven gear transmission, long splined shaft drives little key axle by big cone pinion, because little key pivot pin 33 and swivel nut pin 36 lay respectively in the flat groove 34 of title of double-layer bumper guide pin bushing 38 upper and lower sides, need unload thereby make when swivel nut 37 is enclosed within, or can increase cushion space during the nut of screwing on, strengthen cushion effect, impact can finish several times and unload, or the task of the nut of screwing on.
