Abstract
The utility model relates to an automatic saw grinding machine, which belongs to the cutter grinding machine field. The automatic saw grinding machine is characterized in that the two ends of a worm-wheel shaft are respectively provided with a grooved wheel; one end of the worm-wheel shaft and the inner side of the grooved wheel are also provided with a cam; the outer side of the cam is provided with a driven rod which is sliding fitted with the outer edge of the cam; the driven rod is mutually connected with a grinding head through a lever; the rotation of the grooved wheel and the cam can ensure a grinding wheel to automatically and intermittently grind each tooth of the saw blade in turn. The utility model has the characteristics of compact structure and convenient adjustment, and is capable of quickly and automatically sharpening belt saw blades, etc.
Description
The utility model belongs to the cutter grinding machine field, specifically a kind of automatic saw sharpener.
As everyone knows, the bistrique lifter of existing saw sharpening machine, its structure generally adopts a wedge to contact with the bistrique connecting rod, rely on the translation of wedge and promote the bistrique connecting rod and drive emery wheel and move up and down, play the effect of sharpening sawtooth, this Wedge structure bottom surface and body frictional force are bigger, service time, length just caused wearing and tearing slightly, in addition, because the conversion frequency of translation can not be very fast before and after the wedge, also just influence the speed of sharpening sawtooth, and also bi-metal bandsaw blades has not been carried out the special equipment of sharpening in the market.
The purpose of this utility model just is to provide a kind of automatic saw sharpener, sharpening bands for band, hacksaw blade etc. automatically and quickly.
Feature of the present utility model is: the worm-wheel shaft two ends are respectively equipped with a sheave, also are provided with a cam in worm-wheel shaft one end, sheave inboard, and the cam outside is provided with a follower lever that is slidingly matched with the cam outer, and follower lever links to each other with the bistrique connecting rod by lever.
The utility model can also reach by following measure: the contacted end of follower lever and cam is provided with a roller, be provided with a slide block in the chute of sheave, slide block connects with fork, the pull bar of hinge joint mutually, pull bar can be swung around the shaft, and follower lever one end is rotatably assorted by axle sleeve and turning cylinder.
The utlity model has structure tightly play, easy to adjust, can carry out sharpening to band saw, bow saw etc. quickly and automatically.
Description of drawings:
Fig. 1, structural representation of the present utility model also is a kind of embodiment schematic diagram.
Mark among the figure: fork 1, slide block 2, worm-wheel shaft 3, sheave 4, worm shaft 5, cam 6, roller 7, follower lever 8, lever 9, mill arbor wheel 10, grinding wheel spindle 11, slide rail 12, bistrique sliding support 13, bistrique connecting rod 14, emery wheel 15, the headstock 16, locating wheel 17, feeding pawl 18, pull bar 19, rotating shaft 20, clamper 21.
Embodiment: grinding wheel spindle 11 by bearing fixing on bistrique sliding support 13, its two ends are respectively equipped with emery wheel 15 and mill arbor wheel 10, also be provided with bistrique connecting rod 14 on the bistrique sliding support 13, and be slidingly matched by dovetail groove and slide rail 12, worm screw, worm gear cooperate with worm shaft 5, worm-wheel shaft 3 respectively, worm and wheel is meshed, and worm shaft 5, worm-wheel shaft 3 two ends be respectively equipped with a drive, and two drives link to each other by the driving wheel of V-belt with mill arbor wheel 10 and motor respectively.Worm-wheel shaft 3 two ends respectively are provided with a sheave 4, the interior chimeric slide block 2 that has of dovetail groove on the sheave 4, fixing with the fork 1 that pull bar 19 is hinged with slide block 2, pull bar 19 is fixed on the headstock 16 by rotating shaft 20, pull bar 19 1 ends are provided with feeding pawl 18, be provided with four locating wheels 17 around the headstock 16, on the headstock 16, also be provided with a clamper 21, worm-wheel shaft 3 one ends, sheave 4 inboards are fixed with a cam 6, cam 6 outers are slidingly matched with the roller 7 that is connected with follower lever 8, and follower lever 8 other ends, bistrique connecting rod 14 1 terminations and rotating shaft 20 link to each other with lever 9 jointly.
Interlock mode of the present utility model is: Motor Drive worm shaft 5, worm screw drives worm-wheel shaft 3 and worm gear rotates, drive on the worm shaft 5 drives mill arbor wheel 10 through the V-belt rotate emery wheel 15, worm-wheel shaft 3 makes cam 6 and sheave 4 produce interlock,, the rotation of cam 6 moves up and down on the one hand owing to promoting follower lever 8, the lever 9 that is connected with follower lever 8 is 20 reciprocally swingings around the shaft, lever 9 promotes bistrique connecting rod 14 again and bistrique sliding support 13 moves up and down on slide rail 12, thereby emery wheel 15 just can be finished the action of sharpening sawtooth: on the other hand because the rotation of sheave 4, through fork 1 pushing drawing rod 19 20 reciprocally swingings around the shaft, feeding pawl 18 with pull bar 19 approximate seesawing, makes saw blade by phased manner to a direction motion thereby can promote sawtooth successively above the headstock 16.
The utility model is clipped in bands for band on the headstock 16 through clamper 21 around locating wheel 17 in use, adjusts slide block 2 and makes feeding pawl 18 every distances that saw blade can be promoted a tooth forward that once move back and forth.Actuating motor, the roller 7 of cam 6 outers contact, follower lever 8 drive lever 9 and swing up and down, and 14 on the bistrique connecting rod that is attached thereto drives the 13 reciprocal elevating movements of bistrique sliding support, and 15 pairs of sawtooth of the emery wheel of rotation carry out grinding.The sheave 4 that rotates, slide block 2 drive feeding pawl 18 by fork 1 and move, promote saw blade and advance, the 13 every back and forth liftings of bistrique sliding support once, feeding pawl 18 pushed away a tooth pitch, sawtooth of 15 reconditionings of the emery wheel of rotation.Tooth of saw blade, a tooth ground intermittently travel forward, and emery wheel carries out sharpening to each sawtooth successively, thereby has realized the working cycles of automatic reconditioning sawtooth.
The utility model also can carry out reconditioning to hacksaw blade by changing the headstock 16.
