Description
Technical field
The present invention relates to a kind of dress cutter mechanism, particularly relate to a kind of on the reciprocating motor cutting tools mechanism of loading, unloading saw blade cutter fast.
Background technology
Be used at present the reciprocating motor cutting tools on the mechanism of dress cutter, mostly be and take artificial handling method, promptly be earlier the cutter saw blade to be packed in the cutter positioning groove of reciprocating motor cutting tools, tighten setscrew by hand by the operator then, the cutter positioning is entered duty in cutting the saw operating position; When needs removal cutter saw blade, loosen setscrew, cutter is withdrawed from the groove of cutter positioning take off.This artificial handling method is pretty troublesome, and will consume a lot of unproductive times, thereby increases production cost.
Summary of the invention
Purpose of the present invention is exactly in order to remedy above-mentioned defective, a kind of mechanism that can realize fast quick-mounting cutter or removal cutter by a simple action is provided, thereby can saves a lot of unproductive times, and reduce production costs.
The objective of the invention is by providing a kind of fast quick-mounting cutter mechanism to realize with reciprocating motor cutting tools of following structure, it is based on a normal reciprocating power saws cutting tool, includes the base that the body of power supply connecting device, reciprocating motor cutting tools and being used for of being connected with body amplexiform with the machined material plane.
Cutter rod end at the body of described reciprocating motor cutting tools is connecting a fast quick-mounting cutter mechanism, described fast quick-mounting cutter mechanism includes a band step eccentric inner hole and exposes the clamping knob of handgrip, described step endoporus includes hole under the large diameter off-centre that goes up hole and minor diameter, on described major diameter, hold in the hole and fixing a torque spring, the hole is in 90 ° of scopes of extremely big footpath, small column surface periphery under the off-centre of described minor diameter, be provided with a curved surface that contains the rounding off of different radii size, path place at described clamping knob step endoporus, assembling one with the level, the positioning sleeve of hollow, in the hole of described positioning sleeve, assembling the fast quick-mounting cutter reciprocating lever of a hollow, in described fast quick-mounting cutter reciprocating lever hole, assembling one supplies the insertion saw blade to amplexiform fixing cushion block, one radial hole is arranged at the middle part of described positioning sleeve and install the spring base sleeve therein successively, hold out against back-moving spring and tight lifting pin, place, big footpath at the step endoporus of described clamping knob, assembling one and clamping reduction torsion spring, bottom at described positioning sleeve, install shaft block ring and cutter head pad, be used for the axial location of clamping knob.At the middle part of described positioning sleeve, also have one to become with the described pin-and-hole that radially holds out against that device has a fixing pin in another radial holes of 180 ° of directions, this fixing pin and locate with the radial hole pin joint of fast quick-mounting cutter reciprocating lever and cushion block.
The cushion block of described bar shape has a vertical mounting plane and terminal both sides have the locating slot that is formed by two protuberances, the cutter of dress cutter mechanism of the present invention (saw blade) just amplexiforms and compresses on the rectilinear mounting plane that is installed in cushion block, and is limited in the locating slot.
In 90 ° of scopes of the path periphery of the eccentric inner hole of described clamping knob, be provided with a natural fillet surface that contains the different radii size, like this, when clamping knob is reversed 90 ° (torsion spring is screwed state), described tight lifting pin will produce radial displacement when sliding on it contains the eccentric inner hole curved surface of different radii size; When described tight lifting pin slide into curved surface than the long radius place time, this is the state of Gong the saw blade realization Plug Action of dress cutter mechanism of the present invention, promptly be in the saw blade position of removing stage makeup and costume, at this moment, cutter of the present invention (saw blade) can or be loaded onto again from removal on the dress cutter mechanism; Reverse under the moment of elasticity effect of torsion spring and work as clamping knob, when replying 90 ° of counter-rotatings, when tight lifting pin is forced to entad move the small radii place that slides into curved surface, it does the radial displacement to blade direction, execute normal pressure and hold out against saw blade, its displacement is S, and this is the saw blade clamped condition of dress cutter mechanism of the present invention, promptly is in to cut the saw operating position.
The middle part of described positioning sleeve, have one to become 180 ° of rightabout another radial holes with above-mentioned tight lifting pin radial hole, by this aperture apparatus one fixing pin is arranged, this fixing pin passes the mutual pin joint of radial hole location that fast quick-mounting cutter reciprocating lever enters cushion block to realize axial restraint.
The circular arc head of described tight lifting pin under the elastic force effect that holds out against spring, nestles up the smooth transition curved surface that contains the different radii size in the eccentric inner hole of described clamping knob 90 ° of scopes all the time.
The basic functional principle of dress cutter mechanism of the present invention is by radially mobilizable tight lifting pin, saw blade held out against in the rectilinear mounting plane both sides terminal with it of cushion block have in the locating slot that forms by two protuberances, and have two lugs at the head of saw blade, described two lugs are inlaid on the locating shoulder face of cushion block smooth transition, make saw blade get loose at the Shi Buhui that pumps.
The concrete course of action of dress cutter mechanism of the present invention is described below: in 90 ° of scopes of the path periphery of the eccentric inner hole of described clamping knob, be provided with a curved surface that contains the different radii size, like this, when clamping knob is reversed 90 °, when described tight lifting pin slides on it contains the curved surface of different radii size, will be to produce radial displacement; When described tight lifting pin slide into curved surface than the long radius place time, this is Gong the saw blade insertion of dress cutter mechanism of the present invention or the state of extracting, promptly be in the saw blade position of removing stage makeup and costume, at this moment, the cutter of dress cutter mechanism of the present invention (saw blade) can or be loaded onto again from removal on the dress cutter mechanism; When saw blade is inserted into when in place, the operator looses one's grip and allows clamping knob 90 ° of turn-backs under the effect of button power spring, when tight lifting pin slides into the small radii place of curved surface, it does the radial displacement to blade direction simultaneously, hold out against saw blade, this is the saw blade clamped condition of dress cutter mechanism of the present invention, promptly is in to cut the saw operating position.
So-called fast quick-mounting cutter is exactly to realize the purpose of loading and unloading saw blade by a simple action.Dress cutter mechanism of the present invention only needs clamping knob is twisted 90 °, former saw blade can be drawn off, and behind the new saw blade of packing into, loosing one's grip to clamp the saw blade of newly packing into.
Compared with prior art, the invention has the advantages that only needs to be about to dress cutter mechanism clamping knob of the present invention and to twist 90 ° by a simple action, has just realized the purpose of loading and unloading saw blades, and the action of loading and unloading saw blade is quick, saves unproductive time, reduces production costs.
