Description

Circular saw

The utility model relates to woodworking machinery, the circular saw of annular saws such as the cut-out that is used for woodwork of more clearly saying so, opening processing.

Present circular saw mostly is made of base, frame, workbench, motor, main shaft, belt gear, saw blade etc.Its saw blade is generally perpendicular to workbench, highly, the inclination angle all can not transfer.The sawing degree of depth when that is to say saw blade cut-out, opening, the angle of inclination of saw kerf are all fixed.Really want timing, can only change the saw blade of various outer diameter or the workpiece processing of tilting.So very bother, and do not guarantee the processing dimension of workpiece, range of application is restricted, and is also dangerous.In addition, the adjustment of present circular saw guiding ruler, retaining mechanism are complicated, and the effort of taking a lot of work during use is not very convenient.The protection mechanism of its saw blade more can not the deflection with the inclination of saw blade, and scarcely be with suction port, and dangerous also unhygienic, working condition is relatively poor.

The purpose of this utility model is to overcome above-mentioned shortcoming and defect, provides a kind of height of saw blade and inclination angle all can conveniently adjust, with satisfy processing request better, to add man-hour flexible, applied widely; The adjustment of guiding ruler, lock, unclamp simple, save time quick; The saw blade protection mechanism can be adjusted angle synchronously with saw blade, and the band suction port, safety, health, the circular saw that can improve working conditions greatly.

In order to achieve the above object, the utility model by base, the saw blade that is installed in the frame on the base, rack-mounted motor, rack-mounted workbench, rack-mounted main shaft, is installed in belt gear between motor and the main shaft, is installed on the main shaft and exposes workbench constitutes.A main shaft height and inclination angle regulating system also are installed on the frame.Main shaft, motor and belt gear are installed on this main shaft height and the inclination angle regulating system.Main shaft height and inclination angle regulating system have the preceding bearing that arc groove and bottom have horizontal worm hole by being fixed on the frame, be fixed on the rear support of wearing arc groove after the frame, have horizontal backing pin and both sides, bottom in the middle of having horizontal axis hole along the top, circular arc muscle back of its slip in the arc groove of bearing before the bottom can embed for the worm sector upper front has a fore-stock that a worm hole is arranged in the middle of the lead hole is longitudinally respectively arranged, upper back has that respectively there is an after-poppet in lead hole longitudinally circular arc muscle and the both sides, bottom along its slip in the arc groove that can embed rear support, be fixed on two leads in the lead hole of two groups of correspondences of front and back support, be fixed on the motor supporting seat of two lead rear ends, be installed in the worm hole of fore-stock and stretch out the elevating endless screw of frame, be fixed on the lifting handwheel of elevating endless screw end, be engaged on tape spool hole in top on the elevating endless screw is installed in the horizontal axis hole postmedian band spindle mounting hole of fore-stock with axle lifting worm gear with the worm sector of its underpart, before being installed in the horizontal worm hole of bearing and in the frame right ports and with the revolution worm screw of the worm sector engagement of fore-stock bottom, the turnstile that is fixed on revolution worm screw end constitutes.Motor is installed on the motor supporting seat, and main shaft is installed in the spindle mounting hole.Be positioned at lifting handwheel back on the elevating endless screw one root pointer is installed, the front of frame has the arc scale that indicates angle degree.

During work, rotate the lifting handwheel, just can drive elevating endless screw, lifting worm gear, main shaft successively and make the saw blade lifting.Simultaneously, elevating endless screw drives cursor backward, relatively angle of arc scale rotation.Rotate turnstile, just can drive revolution worm screw, fore-stock successively, so drive lifting worm gear, main shaft, saw blade and lead, after-poppet, motor supporting seat, motor, belt gear integral body is rotated along the arc groove of preceding bearing and rear support.So the angle of inclination of saw blade just is adjusted, and is flexible.Saw kerf is shallow deeply, much oblique angles, can arbitrarily transfer, and is applied widely, can satisfy processing request better.

The guide rail that has scale and interior inclined-plane is being fixed in the front of workbench, fixing the slip guiding ruler that can lock on the guide rail, it by the bottom have can be proper the front of guide rail and above benchmark front, right angle have the handle hole middle upper portion and have the rod support that the spring stop middle part has lock fork shaft and camshaft, be fastened on the horizontal guiding ruler on the rod support, be installed in the eccentric wheel on the camshaft, be installed in eccentric wheel radially and stretch out handle in handle hole outside, be installed on the lock fork shaft rectangular shape chain stay be pressed in upright fork lower end band on the eccentric wheel tiltedly collude be locked in the fork of the lock on the inclined-plane in the guide rail and be installed in spring stop and the chain stay of lock fork between the compression spring constituted.

The slip guiding ruler is moved along guide rail, until on scale, finding suitable position.Hold handle then to pressing down, handle just is raised up to peak with eccentric wheel.This moment, the chain stay of lock fork overcame the elastic force of compression spring to rising and slightly revolution.The upright fork of lock fork is just also slightly turned left to rising simultaneously, is pressed on the interior inclined-plane of guide rail, and the slip guiding ruler is locked on the guide rail.When unclamping, will lift on the handle, eccentric wheel upper edge height descends.The compression spring presses down chain stay, and upright fork is turned right downwards and slightly simultaneously, and guide rail is unclamped.Simply, easily capable, quick.

Also have an installing hole on the after-poppet, fixing a protection dust collection mechanism in the installing hole, it by be fixed on cantilever in the installing hole, be fastened on the cantilever rear end seat, fastening on present the frame that protracts, with little axle be installed in protract the frame front end and be stuck in the frame upper edge of protracting linking arm, be installed in anterior and its guard shield that has suction port above rear portion of linking arm with another little axle and constituted.When saw blade tilted, after-poppet drove cantilever together with seat, the frame that protracts, linking arm and guard shield, can tilt synchronously certainly.Guard shield can be gone up along little axle to be changeed, and can not fall because of there being the linking arm front end to support.Linking arm also can change along another little axially going up together with guard shield, so that work.Suction port can connect the sweep-up pipe dust suction.Safety and sanitation.

Task of the present utility model comes to this and finishes.

The utility model makes height, the angle of inclination of saw blade, and the angle of inclination together with the protection dust collection mechanism all can make things convenient for, flexibly, arbitrarily adjust quickly.Can dust suction during work, safety, health, reliable.The slip guiding ruler of workbench moves, locks, unclamps simply to save time and saves trouble.It is easy to use, can be widely used in the processing such as cut-out, opening of woodwork.
