Description
Technical field
The present invention relates to a kind of abrasive band feeding mechanism.
Background technology
The polishing of current crankshaft journal adopts abrasive band polishing, and belt sander designs defective on abrasive band feeding controls, and hand feed, operating difficulties are leaned in the feeding of belt sander, and the amount of feeding is unstable, wastes bigger.
The patent of invention that publication number is CN103158065A discloses a kind of abrasive band automatic feed mechanism, it includes feeding cylinder, feed rack, take-up case, with be positioned at the spool gear of take-up case box body, two short gears, feeding sector gear, fixing axle and feed shaft, described fixing axle is provided with the spool gear of unidirectional needle bearing II and is fixed on take-up case front end through two ends；Described feed shaft sequentially passes through the short gear being provided with unidirectional needle bearing I, be provided with unidirectional needle bearing III feeding sector gear and another short gear being provided with unidirectional needle bearing I are arranged on the middle part of take-up case, said two short gear is meshed with spool gear simultaneously, and the two ends of feed shaft are installed in the monosymmetric installing hole of take-up case；Described feeding cylinder is fixed on outside the rear end of take-up case, and described feed rack is loaded on feeding cylinder front end, and feed rack is positioned at take-up case top and is meshed with feeding sector gear, and the piston movement of feeding cylinder drives feed rack to move forward and backward.
Above-mentioned abrasive band automatic feed mechanism adopts the engagement of two gears to realize the auto-feed in abrasive band, but, when two gear engagements, abrasive band can be made to produce flexural deformation, and this mechanism strengthens the abrasive band of structure sheaf for being internally provided with, it is not easy to make abrasive band be returned to original shape, and existing abrasive band adopts glue bonding between layers mostly, after oppressing through the engagement of gear, it is easy to cause ftractureing in bonding part, thus abrasive band is damaged.
Summary of the invention
For above-mentioned technical problem, the present invention provides a kind of will not make abrasive band deformation and the abrasive band feeding mechanism destroyed in transmission process.
Realize technical scheme as follows:
Abrasive band feeding mechanism, including take-up case and motor, also include the first friction roller, second friction roller and drivewheel and driven pulley, the two ends of described first friction roller are bearing on take-up case by clutch shaft bearing, one end of first friction roller is provided with axial extension, this extension reaches the outside of take-up case, described driven pulley is fixed on the extension of the first friction roller, second friction roller is arranged on take-up case by the second bearing, described motor is fixed on take-up case, axially axially in parallel with the first friction roller of motor output end, described drivewheel is fixed on the outfan of motor, drivewheel is in transmission connection with driven pulley or coordinates.
The extension of described first friction roller is provided with axle sleeve, and one end of this axle sleeve and the axial end of driven pulley are supported, and the other end of axle sleeve and the box wall of take-up case are supported.
Another axial end of described driven pulley is spacing by the nut being fixed on extension.
Have employed such scheme, when the present invention works, the power exported by motor drives drivewheel to rotate, power is transferred to driven pulley by drivewheel, thus driving first friction roller to rotate, first friction roller imparts power to the second friction roller by friction force, drives the second friction roller to rotate, and sends into thus realizing abrasive band.Due to two friction rollers and abrasive band gross area contact, abrasive band, in being transmitted through kind, will not produce bending bending, thus it is ensured that abrasive band is intact.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Referring to Fig. 1, the abrasive band feeding mechanism of the present invention, including take-up case 1 and motor 2, also include first friction roller the 3, second friction roller 4 and drivewheel 5 and driven pulley 6, the two ends of described first friction roller 3 are bearing on take-up case 1 by clutch shaft bearing, one end of first friction roller 1 is provided with axial extension 3a, this extension 3a reaches the outside of take-up case, the two ends of the first friction roller are equipped with axle, wherein the axle of one end is short, the axial length of the other end, a part for major axis is for assembling with clutch shaft bearing, and another part of major axis defines extension 3a.Described driven pulley 6 is fixed on the extension 3a of the first friction roller 3, driven pulley 6 is circumferentially fixed with extension 3a by spline, in order to limit driven pulley 6 axial displacement, the extension 3a of described first friction roller is provided with axle sleeve 7, the axial end of one end of this axle sleeve 7 and driven pulley 6 is supported, the box wall 1 of the other end of axle sleeve and take-up case is supported, and another axial end of described driven pulley 6 is spacing by the nut being fixed on extension.Second friction roller 4 is arranged on take-up case by the second bearing, and the roll body of the first friction roller 3 and the second friction roller 4 is all in the inside of take-up case 1, and the first friction roller 3 and the second friction roller 4 carry out transmission by friction force.Described motor 2 is fixed on take-up case 1, and axially axially in parallel with the first friction roller 3 of motor 2 outfan, described drivewheel 5 is fixed on the outfan of motor, and drivewheel 5 is in transmission connection with driven pulley 6 or coordinates.Drivewheel 5 and driven pulley 6 preferentially adopt friction roller, between the two by friction force transmission, the volume and weight of drivewheel 5 is all much smaller than driven pulley 6, preferably, the weight of drivewheel 5 is 1st/10th of driven pulley 6, thus after motor quits work, pass through friction force, the inertia making drivewheel cannot drive driven pulley, and driven pulley can also stop in time, is so conducive to improving the precision of transmission sand paper.Drivewheel 5 and driven pulley 6 transmission can also adopt the type of belt drive such as gear, sprocket wheel.
