Description
Technical field
The present invention relates to a kind of adjustable cutter sweep, relate in particular to the cutting machine that a kind of fuselage length and saw blade angle can be regulated within the specific limits, belong to the mechanical ﹠ electrical technology field.
Background technology
Present hand-held cutting machine roughly is divided into two classes: circular saw and chain saw.The characteristics of these cutting machines are: handle is shorter, and being adapted at does not have to cut in the scene of specific (special) requirements to the locus; Volume and weight is relatively large; Saw blade is relatively-stationary, can't adjust angle, and it is convenient, flexible inadequately perhaps to adjust operation.Another kind of cutting tool such as multifunctional motor-driven picking machine (country origin: China; Granted publication number: CN2478326Y), its advantage is replaceable circular saw bit, plucking protective cover can regulate, and there is head to link to each other with the action bars of adjustable length, blemish in an otherwise perfect thing is that this series products must be worked together by the retractor device of adjustable length, itself does not have the telescopic adjustment function, and saw blade does not possess the function that turns to of adjustable angle yet simultaneously.Often under more complicated, the exercisable space-constrained environment, at this time circular saw usually can't touch the object that needs cutting or can't touch accurate position situation at the scene.
Summary of the invention
Purpose of the present invention is exactly the deficiency that will overcome above-mentioned cutting machine, design a kind of fuselage can telescopic adjustment and can be in the process of work rotating saw blade, regulate the cutting machine of cutting angle.
The present invention seeks to realize like this: comprise outer sleeve, a set of cups, inner sleeve, bearing cap, bearing, rotatable platform, bearing pin, seam screw, rocking bar, handle, motor, saw blade, control lever, control lever cover, slide block and butterfly nail; Wherein: outer sleeve is the cylinder type hollow cylindrical shell, and there is the installation heavy stand left side, and outer sleeve upper edge axial restraint is provided with two control lever covers; A set of cups is a support component, and excircle cooperates with outer sleeve, and a set of cups inside is used to place bearing; Inner sleeve is cylindrical, external diameter and outer sleeve internal diameter can be slidingly matched, the inner sleeve right-hand member is provided with the bearing pin engaging lug, inner sleeve axially has a step-like counterbore, 1/4th sections is screwed hole from left end to total length, remaining section is a unthreaded hole, and the diameter of unthreaded hole is greater than tapped bore, and purpose is the weight that alleviates inner sleeve; Rotatable platform is a rectangular metal plate, and the middle part has the bearing pin that is connected with the same inner sleeve of rotatable platform one to connect platform, connects at the bearing pin of rotatable platform on the surface of platform one side to have a sliding tray that is extended to the rotatable platform side by the center; Its whole annexation is: in a set of cups of packing into after rocking bar and the interference of bearing centre hole, rocking bar, bearing and a set of cups integral assembling the outer sleeve left end and by screw and bearing cap with a set of cups and bearing fixing on the installation heavy stand at the outer sleeve left end, the left end of rocking bar is fixedlyed connected with handle, its screwed hole section cooperated with the thread segment of rocking bar after the inner sleeve cover was put into outer sleeve, the bearing pin engaging lug of inner sleeve right-hand member is connected platform with the bearing pin of rotatable platform and connects by bearing pin, one end of control lever is connected with the slide block hinge, slide block is positioned at the sliding tray of rotatable platform, the control lever other end passes two control lever covers on the outer sleeve, control lever puts and is separately installed with the butterfly nail, is used to control the degree of tightness of control lever; Motor is fixedly mounted on the bottom surface of rotatable platform by motor case, and saw blade is fixedly mounted on the machine shaft.
The seam bolt can be installed in the porch of sliding tray in case limited slip block skids off sliding tray, and two extreme positions of cutting machine rotatable platform rotational angle can preestablish when manufacturing and designing as required; Above-mentioned saw blade can be an abrasive disc, also can be section.
Working method: when the external force rotary handle, handle with torque in rocking bar, because rocking bar axial restraint and can only circumferentially rotate and give inner sleeve with transmission of torque, inner sleeve sleeve inner is outside done rectilinear motion, thereby realizes that the telescopic moving of inner sleeve regulates the length of cutting machine body; When needs are regulated the cutting angle of saw blade, unclamp mobile forward or backward control lever behind the butterfly nail that two control levers put, slide block slides in the sliding tray of rotatable platform, drive rotatable platform simultaneously and rotate the purpose of regulating the saw blade cutting angle around bearing pin to reach, regulate locking butterfly nail after the angle, can carry out cutting operation after motor is connected external power supply.
Beneficial effect: cutting machine body of the present invention becomes elongated cylindrical, and cross-sectional area is little, can use flexibly in limited space, and operating personnel also can control smoothly in larger distance; The present invention is simple in structure, is easy to make, and cost is lower, can be widely used in the special occasions such as felling of construction site, earthquake, traffic accident rescue site, fruit tree.
