Description

Automatic band saw sharpener

The utility model relates to a kind of automatic band saw sharpener that is used for sawtooth grinding, particularly relates to a kind of automatic band saw sharpener of band saw for metal.

Existing automatic band saw sharpener is called " band saw sharpener automatically " as a kind of name of " Chinese utility model patent communique " bulletin, the patent No. is the utility model patent technology of " 95242507 ", be made up of support, speed pulley, worm gear, emery wheel lifting linking member, emery wheel riser guide, emery wheel elevating screw, saw blade lowering or hoisting gear, saw blade clamping apparatus, saw blade feed mechanism, emery wheel rolling bearing, the profile of tooth mill that is used for the band saw bar is repaiied work.This technical scheme can be finished the innovation and creation purpose preferably, but exists complex structure, equipment is huge, manufacturing cost is high, selling price is high shortcoming, is unsuitable for wide popularization and application.

The purpose of this utility model is to provide a kind of automatic band saw sharpener so that the structure of saw sharpening machine is simpler, use more convenient, cost is cheaper.

For achieving the above object, the technical solution of the utility model is to have adopted a kind of automatic band saw sharpener, and this automatic band saw sharpener is made of the link gear of frame, reciprocating motion type roll flute mechanism, moving tooth mechanism and connection reciprocating motion type roll flute mechanism and moving tooth mechanism.

The formula motor is stretched by twin shaft by described reciprocating motion type roll flute mechanism, the support bar of fixing on the motor base that reciprocatingly slides, slowing down with belt pulley is main formation, fixedly be equipped with mill on the front end shaft extension of motor and repair emery wheel, fixedly be equipped with belt pulley on the rear end shaft extension of motor, between belt pulley and the deceleration belt pulley by the driving belt driving coupling, the turning cylinder of deceleration belt pulley is fixed on the support bar that reciprocatingly slides, the support bar that reciprocatingly slides is slidedly assemblied in the sliding sleeve of fixing assembling on the frame, be equipped with a cam on the turning cylinder), cam and is assemblied in the axis of rolling bearing sleeve on the sliding sleeve) rolling cooperates.

Described moving tooth mechanism is made up of shifting block and slide bar, and the slide bar slidable fit is in body, and body fixedly is assemblied on the frame.

Described link gear is that the master constitutes by a skid plate, skid plate rotates by a rotating shaft and is assemblied on the bearing, skid plate is assemblied between moving tooth mechanism and the reciprocating motion type roll flute mechanism, one end of skid plate and the tail end of slide bar are slidingly matched, fixing catch press fit on the other end of skid plate and the support bar that reciprocatingly slides.

Can also assemble by two clamping plate in front and back on the frame is the main vertical saw blade frame that constitutes, and the both sides of two clamping plate in front and back are fixed with fastening bolt.

Because the utility model only is made of reciprocating motion type saw sharpening machine structure, moving tooth mechanism and link gear, and is simple in structure small and exquisite, reasonable in design, and manufacturing cost is greatly reduced.Actual measuring and calculating, the manufacturing cost of automatic band saw sharpener of the present utility model only is about 1/3 of a like product, for the wide popularization and application of this product has been created condition.Another characteristics of the present utility model are that the driving force motor of reciprocating motion type roll flute mechanism directly is assemblied on the reciprocating mass, the motor direct-drive emery wheel, and participate in moving back and forth, reduced transmission link, the transmission advantages of simple has reduced power of motor, reduced cost, energy-saving effect is obvious.The utility model is on structural design, reciprocating motion type roll flute mechanism and moving tooth mechanism link mutually by link gear, reciprocating motion type roll flute mechanism and moving tooth mechanism are under the effect of link gear, both direction of motion is opposite, advance-move back-advance-move back ... alternating movement is finished without any confusion the mill of sawtooth is repaiied feeding with sawtooth, and transmission link is few, mill is repaiied action in order, is a kind of simple and practical professional tool of repairing that band saw is ground.

The utility model is further explained and explanation below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of a kind of exemplary embodiment of the present utility model.

As shown in FIG., on the whole, this automatic band saw sharpener is made of the link gear of frame, reciprocating motion type roll flute mechanism, moving tooth mechanism and connection reciprocating motion type roll flute mechanism and moving tooth mechanism.

Formula motor 2 is stretched by twin shaft by reciprocating motion type roll flute mechanism, the support bar of fixing on the motor base 12 that reciprocatingly slides, slowing down with belt pulley 8 is main formation, fixedly be equipped with mill on the front end shaft extension of motor 2 and repair emery wheel 1, fixedly be equipped with belt pulley 3 on the rear end shaft extension of motor, between belt pulley 3 and the deceleration belt pulley 8 by driving belt 5 driving coupling, the turning cylinder 7 of deceleration belt pulley 8 is fixed on the support bar 12 that reciprocatingly slides, the support bar 12 that reciprocatingly slides is slidedly assemblied in the sliding sleeve 15 of fixing assembling on the frame 11, be equipped with a cam 6 on the turning cylinder 7, axis of rolling bearing sleeve 9 rollings that cam 6 and is assemblied on the sliding sleeve 15 cooperate, axis of rolling bearing sleeve 9 is fixed on the adjustable plate 10 by its rotating shaft, design has vertical slotted hole on the adjustable plate 10, adjustable plate 10 by its vertical slotted hole by being bolted on the sliding sleeve 15.The upper-lower position of mobile adjustable plate 10, the maximum mill amount of repairing that can regulate emery wheel 1.Moving tooth mechanism is made up of shifting block 21 and slide bar 16, and slide bar 16 slidable fit are in body 17, and body 17 fixedly is assemblied on the frame 11.Link gear is that the master constitutes by a skid plate 18, skid plate 18 rotates by a rotating shaft 14 and is assemblied on the bearing 13, skid plate 18 is assemblied between moving tooth mechanism and the reciprocating motion type roll flute mechanism, one end of skid plate 18 and the tail end of slide bar 16 are slidingly matched, fixing catch 4 press fit on the other end of skid plate 18 and the support bar 12 that reciprocatingly slides.Also assembling by two clamping plate in front and back 19 on the frame 11 is the main vertical saw blade frame that constitutes, and the both sides of two clamping plate 19 in front and back are fixed with fastening bolt 20.
