Abstract
The utility model relates to a sand belt polishing head which comprises a frame, a motor and a driving wheel connected with a transmission belt of the motor. A sand belt tensioning mechanism consisting of a tensioner, a tensioner swing arm, a spring, a pull rod nut, a tensioner pull rod and a handwheel, and an adjusting mechanism consisting of an adjusting pull rod, an adjusting axle and a pin roll, are arranged on the frame. The sand belt polishing head has the advantages that the depth of parallelism between the adjusting wheel and the axes of the driving wheel and the tensioner can be changed to balance the stress of the sand belt to avoid axial friction, thereby ensuring the smooth operation of the sand belt. The distance between the tensioner and the driving wheel can be adjusted through the adjusting mechanism to adjust the tightness of the sand belt to prevent the deviation of the sand belt and the abrasion of the tensioner pull rod, thereby greatly prolonging the service life of the polishing head.
Description
Technical field
The utility model belongs to the plug processing technique field, particularly relates to a kind of abrasive band polishing head that is used for mandrel surface polishing processing.
Background technology
At present, the abrasive band polishing head that mandrel surface polishing processing is adopted, its structure is: driving wheel and driven pulley drive the abrasive band motion, and driving wheel is by driven by motor, to the not protection of skew that produces in the abrasive band polishing process.Adopt above-mentioned rubbing head; through regular meeting following defective appears: one; run up in the abrasive band when plug polished; the abrasive band is offset to a direction; cause frame and regulating wheel pull bar darker cut channel to occur; and may and frame strength be reduced with the cut-out of regulating wheel pull bar after the long-time wearing and tearing, and then shorten the service life of rubbing head.Its two since support the abrasive band each wheel shaft depth of parallelism influence and when throwing is cut, produced axial friction, cause occurring falling often zoning, so not only increased trouble, and production efficiency be affected to polishing operation.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, can avoid axial rub and can prolong the rubbing head abrasive band polishing head in service life by adjusting each wheel shaft depth of parallelism.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the abrasive band polishing head, comprise: frame, rack-mounted motor, with the driving wheel that the motor driving-belt is connected, it is characterized in that: described frame is provided with and comprises abrasive band strainer that regulating wheel, regulating wheel swing arm, spring, pull-rod nut, regulating wheel pull bar and handwheel constitute and by adjusting pull bar, adjusting the guiding mechanism that wheel shaft and bearing pin constitute.
The utility model can also adopt following technical scheme:
The syndeton of described abrasive band strainer is: by gyroaxis the regulating wheel swing arm is installed at frame one end, regulating wheel swing arm one end connects regulating wheel by axle, the other end connects spring, pull-rod nut successively and is fixed on handwheel on the frame by the handwheel seat, and the regulating wheel pull bar that the one end is connected with pull-rod nut is housed on the handwheel.
The structure of described guiding mechanism is: be fixed with the adjustment wheel shaft in frame one end by bearing pin, adjusting on the wheel shaft has the wheel of adjustment by bearing fixing, adjusts the wheel shaft other end and adjusts pull bar by the bearing pin connection, adjusts pull bar one end and connects the handwheel that is arranged on the frame.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, promptly the abrasive band guiding mechanism is installed in frame one end, and by rotating handwheel, make and adjust pull bar along its axially-movable, by bearing pin the adjustment wheel shaft is rotated around bearing pin, be installed in the adjustment wheel of adjusting on the wheel shaft and also rotate synchronously thereupon, can change the depth of parallelism of adjustment wheel and driving wheel, regulating wheel axis like this, make the stressed balance that reaches in abrasive band, and then can guarantee the abrasive band even running.In addition, by rotating handwheel and driving the axial displacement that the tensioning pull bar is adjusted pull-rod nut, pull-rod nut pulling spring, make its displacement drive regulating wheel swing arm wraparound rotating shaft rotation, can adjust the distance between regulating wheel and the driving wheel like this, realize the degree of tightness adjusting in abrasive band, can prevent the wearing and tearing of its skew and regulating wheel pull bar again, prolonged the service life of rubbing head greatly.
