The utility model content
Technical problem to be solved in the utility model is, a kind of abrasive band tensioning apparatus of simple and reasonable, belt sander that rapid operation is light is provided.
for solving the problems of the technologies described above, the abrasive band tensioning apparatus of the belt sander that the utility model provides, it comprises motor, body, support, driving wheel, driven pulley, the abrasive band, motor is fixedly connected with body respectively with support, driving wheel is fixedly connected with motor, prop up and be erected between driving wheel and driven pulley, be sliding combined with driven wheel carrier on described support, the rotating shaft of driven pulley is fixedly connected with driven wheel carrier upper shed groove, be fixedly connected with location-plate on described body, be fixedly connected with adjustable plate on driven wheel carrier, be provided with spring between location-plate and adjustable plate, one end of spring is fixedly connected with location-plate, the other end of spring coordinates with adjustable plate, on described body, eccentric wheel is installed, eccentric wheel is provided with the tape swapping plane, during the close driving wheel of adjustable plate, tape swapping plane and adjustable plate are fitted.Utilize eccentric wheel to adjust the compression distance of spring, change the distance between driving wheel and driven pulley, simple in structure to reach the purpose of changing the abrasive band, rapid operation is convenient, can quick-replaceable the abrasive band.
As preferably, be fixedly connected with projection on described driven wheel carrier, the rotating shaft that the regulating rod that has been threaded on projection, regulating rod rotate through after projection with driven pulley fits.After more finish changing in the abrasive band, adjust regulating rod, make driving wheel and driven pulley reach poised state.
As preferably, be connected with handle on described eccentric wheel, described body is provided with the resilient key that the restriction eccentric wheel rotates a circle, and resilient key and adjustable plate are located at eccentric both sides.Rotate by rotary handle band movable eccentric wheel, utilize simultaneously resilient key to eccentric position-limiting action, eccentric wheel is only had towards a direction rotation ability Compress Spring, pull-off spring during to another direction rotation.
After adopting above structure, the abrasive band tensioning apparatus of belt sander of the present utility model compared with prior art, have the following advantages: pass through operating grip, make the tape swapping plane on eccentric wheel fit or separate with limited block, change the distance between driving wheel and driven pulley, to reach the purpose of changing the abrasive band, the tape swapping operation is not only easy to be laborsaving, and after the replacing of abrasive band, can also further adjust driven pulley, make driving wheel and driven pulley reach poised state, make whole belt sander stable working, improved Product Safety and reliability.
Description of drawings
Fig. 1 is structure chart of the present utility model;
Fig. 2 is rearview of the present utility model.
Wherein: body 1, support 2, driving wheel 3, driven pulley 4, abrasive band 5, driven wheel carrier 6, rotating shaft 7, open slot 8, location-plate 9, adjustable plate 10, spring 11, locking nut 12, eccentric wheel 13, tape swapping plane 14, projection 15, regulating rod 16, handle 17, resilient key 18.
The specific embodiment
The utility model will be further described by reference to the accompanying drawings below by embodiment.
as Fig. 1～shown in Figure 2, the abrasive band tensioning apparatus of the belt sander that the present embodiment provides, it comprises motor, body 1, support 2, driving wheel 3, driven pulley 4, abrasive band 5, motor is fixedly connected with body 1 respectively with support 2, driving wheel 3 is fixedly connected with motor, support 2 is located between driving wheel 3 and driven pulley 4, be sliding combined with driven wheel carrier 6 on described support 2, the rotating shaft 7 of driven pulley 4 is fixedly connected with driven wheel carrier 6 upper shed grooves 8, be fixedly connected with location-plate 9 on described body 1, be fixedly connected with adjustable plate 10 on driven wheel carrier 6, be provided with spring 11 between location-plate 9 and adjustable plate 10, one end of spring 11 is fixedly connected with location-plate 9, the other end of spring 11 coordinates with adjustable plate 10, on described body 1, eccentric wheel 13 is installed, eccentric wheel 13 is provided with tape swapping plane 14, during adjustable plate 10 close driving wheel 3, fit with adjustable plate 10 in tape swapping plane 14, be fixedly connected with projection 15 on described driven wheel carrier 6, regulating rod 16 has been threaded on projection 15, regulating rod 16 contacts with the rotating shaft 7 of driven pulley 4 after passing projection 15, make driven pulley 4 and driving wheel 3 reach poised state by adjusting regulating rod 16, for fear of cause regulating rod 16 and projection 15 to occur loosening because of vibrations, between projection 15 and regulating rod 16, locking nut 12 is installed, be connected with handle 17 on described eccentric wheel 13, described body 1 is provided with the resilient key 18 that restriction eccentric wheel 13 rotates a circle, resilient key 18 and adjustable plate 10 are located at the both sides of eccentric wheel 13.
operation principle: when handle 17 is in level, tape swapping plane 14 and the adjustable plate 10 of eccentric wheel 13 are fitted, this moment, spring 11 was compressed, driven wheel carrier 6 drives driven pulley 4 near driving wheel 3, driven pulley 4 separates with abrasive band 5, change the abrasive band 5 of wearing and tearing, after more finish changing in abrasive band 5, as Fig. 2 direction handle 17 that turns clockwise, when rotating handle 17 to the upright position, separate with adjustable plate 10 on the tape swapping plane 14 of eccentric wheel 13, spring 11 relies on the tension force of self to promote adjustable plate 10, fitted in driven pulley 4 and abrasive band 5, adjust again regulating rod 16, make driving wheel 3 and driven pulley 4 be in poised state, complete the replacing in abrasive band 5.
As shown in Figure 2, handle 17 is in level, the effect of resilient key 18 makes handle 17 half-twist clockwise, could realize the tape swapping plane 14 of eccentric wheel 13 and separating of adjustable plate 10, if continue rotation clockwise, the larger diameter end of eccentric wheel 13 will be blocked by resilient key 18, and handle 17 can't continue rotation clockwise, therefore handle 17 can only rotate to horizontal level more counterclockwise, and tape swapping plane 14 and adjustable plate 10 are fitted.
