Description

Bench saw

The utility model relates to woodworking machinery, more clearly says so to be used for the bench saw of timber and the processing of half-finished saw thereof.

Present bench saw mostly is made of the elevating mechanism of the slew gear of frame, workbench, slew gear bearing, saw blade, saw blade, motor, saw blade, saw blade protective cover etc.But the slew gear of saw blade wherein and elevating mechanism are all complicated, and processing, assembly period is long, difficulty is big, and cost is also high.The Chinese patent of ZL99257810.8 number " circular saw " by name comes to this.It makes slew gear and elevating mechanism with the worm and gear principle, and complex process, difficulty of processing are big.In addition, the bench saw saw blade in past is installed on the main shaft, gives main shaft with motor by drive pulley, driving-belt, driven pulley transmission, and is also complicated.Because mechanism's complexity, its volume is also big, and floor space is also big.

The purpose of this utility model is to overcome above-mentioned shortcoming and defect, provides a kind of slew gear of saw blade and elevating mechanism simple, and processing technology is simple, and motor transmission mechanism is also simple; Production efficiency is higher, and production cost is lower, the bench saw that volume and floor space are all less.

In order to achieve the above object, the utility model bench saw by frame, be fixed on have on the frame slotted hole with the workbench that passes saw blade, be fixed on bearing on the workbench, be installed in slew gear on the bearing, be installed in reciprocating mechanism on the slew gear, be installed in motor on the reciprocating mechanism, be installed in the saw blade on the axle of motor and the saw blade shield components that is installed on the reciprocating mechanism is constituted.Bearing has two of preceding bearing and rear supports.Be semicircle in the middle of each bearing and wherein be with its left side of circular-arc slotted hole to be wildhaber-novikov gear.Two limited blocks about being fixed with on the preceding bearing.Slew gear by the rotary support in the middle of the bearing before and after being installed in, be fixed on the rotary support and be inlaid in before and after in the circular-arc slotted hole of bearing former and later two circular-arc guide runners, be fixed on its rear and front end on the rotary support fixing respectively with the gear shaft of former and later two pinions of front and back bearing left circles gear with curved teeth engagement, be fixed on the gear shaft front end knob, be installed in the locking device of forming with screw and rotary handle and pressing plate the rotary support front and constituted.

Unscrew rotary handle, clamp loose is pressed in before power on bearing and the rotary support.Twist knob again, rotate together with gear shaft and the pinion on it.Two pinions just with the wildhaber-novikov gear of the front and back bearing of its engagement on roll, and then drive whole slew gear and on the bearing of front and back, rotate together with reciprocating mechanism, motor and saw blade.Guide runner slides in the circular-arc slotted hole of front and back bearing respectively before and after this moment, has guaranteed the relative position between slew gear and the front and back bearing.Until slew gear run into be fixed in before limited block on the bearing.When slew gear forwards the angle that needs to, tighten rotary handle, make pressing plate that preceding bearing and rotary support are compressed pinning, can saw processing.

Circular-arc angle scale is also being fixed along its circular-arc slotted hole edge in preceding bearing front, with the angle of accurate adjustment slew gear.

Reciprocating mechanism is by being fixed on the rotary support and middlely having the vertical slotted hole of vertical slotted hole both sides and have the guide plate that four vertical little slotted hole its underparts have horizontal slotted hole, have the motor bearing plate that motor installing hole and four aperture bottoms have the convex edge hypotenuse, to fix the slide in four apertures that four vertical little slotted holes that four screws on it pass guide plate are fixed on the motor bearing plate, the bottom with protruding flat key with can be in the horizontal slotted hole that is installed in guide plate along its guiding yoke plate of band inclined-plane, rear portion front end tape spool that slide to screw, the horizontal slotted hole that passes guide plate is fixed on the convex shoulder double-screw bolt on the yoke plate that leads, the rear portion that is fixed on the guiding yoke plate leans against the connecting plate of the hypotenuse inboard, convex edge of motor bearing plate, the traction screw that the thin neck of axial screw middle front part that the rear portion screw rod is installed in the guiding yoke plate is installed in the front aperture of guide plate and fastens with end cap, the handwheel that is fixed on the traction screw front end constitutes.Motor is installed on the motor bearing plate.

Slide is fixed on the motor bearing plate by four screws, but guide plate and the locking of motor bearing plate should can not be guaranteed that slide and motor bearing plate slide in four vertical little slotted holes of guide plate.The convex shoulder bolt also can not be fixed on the locking of guiding yoke plate on the guide plate, and the slip of yoke plate along the horizontal slotted hole of guide plate should guarantee to lead.

Turn handwheel and just drive traction screw rotation, traction screw is pulled out or is sent to by the screw thread yoke plate that will lead, by the horizontal slotted hole slip of protruding flat key along guide plate.Connecting plate on the guiding yoke plate forces the motor bearing plate to move up and down together with four vertical little slotted holes of slide along guide plate together with the convex edge hypotenuse on its inclined-plane compressing motor bearing plate at last.Motor is installed on the motor bearing plate, and saw blade is installed on the axle of motor.So saw blade just moves up and down thereupon.

The saw blade shield components is made of the support plate that is fixed on sliding base rear end with securing member, the protective cover that is fixed on the band suction port on the support plate with securing member.When reciprocating mechanism moved, slide moved simultaneously, and the saw blade protective cover also just moves up and down simultaneously.Because of reciprocating mechanism is fixed on the slew gear, when slew gear turned round, the saw blade protective cover is also revolution thereupon naturally.

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

The utility model provide a kind of slew gear with gear drive, reciprocating mechanism with screw rod, inclined-plane drive simple in structure, processing technology is simple, production efficiency height, the bench saw that volume is little, floor space is little.Compare in the past, its production cost has descended 5%～15%, and it can be widely used in timber and the processing of half-finished saw thereof.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.
