Abstract
The utility model relates to a tooth grinding device specially used for dual-metal saw bands, which is composed of a power transmission part, a grinding shaft part, a saw blade support frame part and a grinding and tooth delivering control part. Through the grinding and tooth delivering control part, the automatic grinding for saw teeth can be realized. The saw band can be changed from once use to many times use after the saw band is grinded, so the service life of the saw band is extended, and the use effect is enhanced.
Description
The utility model relates to a kind of saw sharpening machine, is mainly used in the reconditioning of sawtooth, particularly is applicable to the toothed reconditioning of double metal saw.
Existing double metal saw belt all is disposable uses, and waste is serious.Utility application 89213933.1, notification number CN2061497U disclose the mechanism of a kind of " gear grinding machines ", and mainly by the grinding wheel spindle part, bed body and feeding are partly formed, and can only be suitable for the repairing of machine hacksaw blade.At present, the special equipment that lacks a kind of suitable double metal saw belt roll flute on the market.
The purpose of this utility model provides a kind of saw sharpening machine that is used for the double metal saw belt roll flute.
The utility model is to realize like this, it is mainly by motivation transfer motion part, the grinding wheel spindle part, the saw blade bracket portion, grinding, send the tooth control section to form, grinding, send the tooth control section by eccentric wheel, connecting rod, the grinding wheel spindle lifting screw, planker, be fixed on the middle skewback of planker, and be fixed on that the ratchet bearing on the planker left side and adjusting handle link to each other with the calcaneus branches seat can promote the ratchet that saw blade moves, be installed in the grinding wheel spindle below in addition, compositions such as the tooth pitch adjustable plate on saw blade limit, eccentric wheel links to each other with the worm gear reducer worm screw of motivation transfer motion part, connecting rod can make planker produce by eccentric drive and move back and forth, planker is in the grinding wheel spindle below, the grinding wheel spindle lifting screw contacts with skewback by the pulley of lower end, reciprocating motion along with planker, the saw band that at every turn makes ratchet moves a tooth, grinding carriage moves up and down, and emery wheel carries out grinding to sawtooth.
The utility model advanced design, rational in infrastructure, it is big to have a use, easy maintenance, adjusting, correcting range, characteristics such as roll flute stable performance, but to a small amount of broken teeth and the also grinding of not equally spaced saw band.Saw band is sharp after grinding, tooth pitch is even, and angle is correct, and double metal saw belt becomes disposable use into using repeatedly behind sharpening, prolonged service life, increases economic efficiency.The utility model has been filled up the blank of double metal saw belt saw sharpening machine.
Accompanying drawing 1 is the utility model grinding, send the master of tooth control section to look schematic diagram
Accompanying drawing 2 for the utility model grinding, send the schematic rear view of tooth control section
The explanation of accompanying drawing sign: 1 is connecting rod, and 2 is planker, and 3 is grinding carriage, 4 is grinding wheel spindle, and 5 is lifting screw, and 6 is emery wheel, 7 is skewback, and 8 is ratchet, and 9 is pawl base, 10 is bearing, and 11 is adjusting handle, and 12 is the tooth pitch adjustable plate, 13 is body frame, and 14 is pressing plate, and 15 is leaf spring, 16 is screw, and 17 is double metal saw belt, and 18 is handle.
Below in conjunction with drawings and Examples this loop is described further with novel.
The utility model is mainly by motivation transfer motion part, the grinding wheel spindle part, and the saw blade bracket portion, grinding send the tooth control section to form.
Motivation transfer motion part rotates the worm screw of worm gear reducer by motor by V belt, belt pulley on the worm shaft is given grinding wheel spindle 4 by the V belt transmission with transmission of power again, the worm-wheel shaft of reduction box has driven the eccentric wheel rotation, and eccentric wheel drivening rod 1 affects planker 2 to produce and moves back and forth.
The grinding wheel spindle part is equipped with the wheel rim emery wheel identical with zigzag fashion 6 as shown in drawings on the grinding wheel spindle, grinding wheel spindle drives emery wheel and rotates.Lifting screw 5 is housed on the grinding carriage 3, and along with lifting screw 5 drives grinding carriage up and down about in the of 3, emery wheel 6 when emery wheel 6 contacts with sawtooth, carries out grinding to sawtooth also along with advance and retreat.
The saw blade bracket portion is by body frame 13 and pressing plate 14, leaf spring 15 and four feets are formed, double metal saw belt 17 can be contained between pressing plate 14 and the body frame 13, and tighten the screws compresses double metal saw belt 17 by leaf spring 15, and other four feets play a supportive role.
Grinding, send the tooth control section by eccentric wheel, connecting rod 1, grinding wheel spindle lifting screw 5, planker 2, be fixed on the skewback 7 in the middle of the planker, and be fixed on that the ratchet bearing 10 on the planker left side and adjusting handle 11 thereof link to each other with the calcaneus branches seat can promote the ratchet 8 that saw blade moves, be installed in the grinding wheel spindle below in addition, tooth pitch adjustable plate 12 compositions such as grade on saw blade limit.Above-mentioned running part has been introduced, and the worm-wheel shaft of reduction box has driven the eccentric wheel rotation, affects planker 2 to produce by connecting rod 1 and moves back and forth.Planker is in the grinding wheel spindle below, and grinding wheel spindle lifting screw 5 contacts with skewback 7 by the pulley of lower end, and along with the reciprocating motion of planker, ratchet 8 makes sawtooth move a tooth at every turn, and grinding carriage moves up and down, and emery wheel carries out grinding to sawtooth.
In practice, can regulate like this.Rotate the lifting screw of grinding carriage; make a little higher than tooth top of emery wheel extreme lower position end; the test running of starting (crawl) motor; at this moment rotary pawl adjusting handle 11 can carry out emery wheel and sawtooth centering, shuts down then; the flank of tooth (claiming first tooth) after regulating tooth makes before the tooth pitch adjustable plate circular arc end face a little more than second tooth apart from adjustable plate with emery wheel centering; tighten screw,, can make double metal saw belt 17 move a tooth by ratchet.
Along with each reciprocating motion of planker 2, ratchet 8 slides one back and forth on tooth pitch adjustable plate 12, makes sawtooth move a tooth at every turn.Grinding wheel spindle lifting screw 5 contacts with skewback by the pulley of lower end, skewback is fixed on the planker, also and then reciprocating motion of each reciprocating motion skewback along with planker, make the grinding wheel spindle lifting screw along with moving up and down, because the elevation that skewback moves is greater than tooth depth, make when ratchet sent tooth when planker moved to the right side, emery wheel rises and sawtooth is not carried out grinding, and ratchet is not when sending tooth sliding, motion along with planker, influence lower grinding wheel frame lifting screw at skewback and move up and down, emery wheel also carries out grinding after sawtooth is contacted.
When being used for Halfway Stopping, handle 18 uses.
By above-mentioned grinding, send the tooth control section can realize that automatic roll flute to double metal saw belt, the utility model are the double metal saw belt special use saw sharpening machines that does not still have at present.
