The utility model content
can't auto-tensioning in order to solve in prior art burnishing device, need the inefficient problem of manual adjustments at every turn, the utility model provides a kind of screw rod burnishing device, concrete scheme is as follows: a kind of screw rod burnishing device, comprise motor and the guard shield that is arranged on outside motor, be provided with driving pulley on the motor shaft of motor in guard shield, driven pulley is connected with driving pulley by the abrasive band, it is characterized in that, in described outer cover, driven pulley one side is provided with two relative sliding trays, also comprise an automatic takeup, described automatic takeup comprises fixed block, spring, adjusting nut, mobile screw and rectangular frame, described fixed block is fixed in guard shield driving pulley and is connected on the circle center line connecting position with driven pulley and is connected with a mobile screw in the side near driven pulley, described spring and adjusting nut are sleeved on mobile screw, spring is conditioned nut and is pressed abd fixed on fixed block one side, the adjusting nut other end is fixedly connected with rectangular frame, rectangular frame is equipped with fixed axis with respect to adjusting nut one side, described fixed axis passes the center of circle of driven pulley and stretches out from the both sides of rectangular frame 505 driven pulley is fixed on the sliding tray of outer cover both sides.
Preferably, described driving pulley is identical with the driven pulley radius.
Preferably, the both sides of described guard shield are semicircular arc, and its radius is slightly larger than the radius of driving pulley and driven pulley, two belt wheels is contained in the both sides of guard shield.
Preferably, described fixed axis is for removably connecting.
The utility model had once added automatic takeup on original screw rod burnishing device, avoided repeatedly regulating manually the abrasive band rate of tension, increase substantially the polished amount to screw rod within the unit interval, improved operating efficiency, saved manpower and materials and time.Motor of the present utility model and belt wheel concentric, the both sides of guard shield are semicircular arc, and radius is slightly larger than the radius of belt wheel and driven pulley, make it can just be contained in both sides in guard shield, have saved the space and have lowered manufacturing cost.In addition, passing the axle that is fixed on sliding tray in the utility model from the driven pulley center of circle can quick-detachment, is convenient to keep in repair when needed or change.

Attached number in the figure explanation: 1-guard shield, 2-abrasive band, 3-driving pulley, 4-driven pulley, 5-automatic takeup, 501-fixed block, 502-spring, 503-adjusting nut, 504-mobile screw, 505-rectangular frame, 506-fixed axis, 6-sliding tray.
The specific embodiment
As depicted in figs. 1 and 2, screw rod burnishing device of the present utility model comprises that the driving pulley 3 that is arranged on motor shaft is fixed in guard shield 1, driven pulley 4 is connected with driving pulley 3 by abrasive band 2, the interior side near driven pulley 4 of guard shield 1 is provided with two relative sliding trays 6, and an automatic takeup 5 that comprises fixed block 501, spring 502, adjusting nut 503, mobile screw 504 and rectangular frame 505 is installed between two belt wheels.Automatic takeup 5 is fixed on two belt wheel circle center line connectings by fixed block 501, fixed block 501 is fixedly connected with a mobile screw 504 near a side of driven pulley 4, spring 502 and adjusting nut 503 are sleeved on mobile screw 504, adjusting nut 503 is squeezed in fixed block 501 1 sides with spring 502, and spring 502 is compressed.The other end of adjusting nut 503 connects a rectangular frame 505, rectangular frame 505 is with respect on mobile screw one side, fixed axis 506 being installed, fixed axis 506 passes the center of circle of driven pulley 4 and stretches out from the both sides of rectangular frame 505 driven pulley is fixed on the sliding tray 6 of outer cover both sides, and driven pulley 4 can be moved horizontally on sliding tray 6.
During installation, 2 pairs, abrasive band driven pulley 4 applies one towards the power of driving pulley 3, makes the spring 502 of automatic takeup 5 compressed.During work, starter motor, driving pulley 3 begin to rotate, and driven pulley 4 is driven by abrasive band 2, forms a transmission mechanism.Screw rod is contacted abrasive band 2 polish, to abrasive band 2 application of forces, abrasive band 2 is elongated after long-time the use gradually along with screw rod.This moment, 2 pairs, abrasive band driven pulley 4 applied forces reduced, compressed spring 502 is discharged, beginning promotes adjusting nut 503 to the right, spring 502 discharges elastic force and is conducted to rectangular frame 505 by adjusting nut 503, axle 506 on rectangular frame 505 passes driven pulley 4 centers of circle and stretches out on the sliding tray 6 that is fixed on both sides from rectangular frame, and then promotion driven pulley 4 moves to the position that the abrasive band is tightened again to the right on sliding tray 6.
For the ease of installing and save the space, driving pulley 3 of the present utility model is identical with the radius of driven pulley 4, and the both sides of outer cover 1 are semicircular arc, and its radius is slightly larger than the radius of two belt wheels, make two belt wheels can just be arranged on outer cover 1 interior both sides, so compact, the conserve space of equipment overall structure.Two belt wheel radiuses are in together on the same level position mutually, and during rotation, the abrasive band moves horizontally, and convenient screw rod are carried out sanding operation.
For the ease of installing and changing, fixed axis 506 is for removably connecting.After long-time the use, driven pulley 4 moves repeatedly, unavoidably weares and teares, and pull down fixed axis 506 and just can place under repair or change driven pulley,
the above is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, anyly be familiar with the technical staff of this patent within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned prompting is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of the utility model scheme.
