Description
Technical field
The invention belongs to the sawing field of mechanical technique, more particularly relate to the design of the sweep-saw of steel wire transmission.
Background technology
Traditional sweep-saw by base, be fixed on casing on the base, be installed in the connecting rod of lower shake-changing arm on the casing and upper rocker arm, connection lower shake-changing arm and upper rocker arm rear end, the saw blade stretcher that is fixed on workbench and motor on the base, is installed in eccentric wheel on the axle of motor, is installed in rocking bar between eccentric wheel and the lower shake-changing arm, is installed in the saw blade clamper of lower shake-changing arm and upper rocker arm front end and is installed in the upper rocker arm front end with little axle is constituted.Its casing is an aluminum alloy die casting.
Above-mentioned quite complicated because of its structure, shape by transmission mechanism that motor-eccentric wheel-rocking bar-lower shake-changing arm-connecting rod-upper rocker arm-the saw blade clamper constitutes, processing technology is also complicated, and production cost is higher, and vibrations are big during work, noise is big.Sweep-saw does not generally fix on the ground, and is therefore, often because of shaking the excessive complete machine displacement that causes, very dangerous during work.In addition, the casing mould manufacturing expense costliness that aluminium alloy compression casting is made, material cost is also very high.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned shortcoming and defect, provides that a kind of transmission mechanism and component structural thereof are very simple, processing technology is improved greatly; Vibrations are little during work, noise is little, can not cause complete machine displacement, not only have been beneficial to environmental protection but also safe and reliable; The mould manufacturing expense is lower, the sweep-saw of the steel wire transmission that material and production cost reduce greatly.
In order to achieve the above object, the present invention includes base, be installed in casing, workbench and motor on the base, be installed in saw blade clamper and the saw blade in the casing and be installed in base and casing in transmission mechanism.Transmission mechanism is by the flywheel on the axle that is fixed on motor, off-centre is fixed on the little axle on the flywheel, be sleeved on the roller on the little axle, be sleeved on the roller and have the slide block of left and right arms with its elongated slot, be fixed on and have left and right sides guide hole on the casing and borrow guide block on its left and right arms that is set in slide block, be fixedly connected on the long steel wire and the short steel wire at slide block two ends respectively, be installed in the guiding wheels on the casing, be installed in two guide rails up and down that have guide groove on the casing, afterbody is installed in two the saw blade clampers up and down in the lower guideway respectively and the steel wire strainer that is installed on the casing is formed.The guiding wheels comprise the 1st propelling sheave, the 2nd propelling sheave that is positioned at the casing lower right side, the 3rd propelling sheave that is positioned at the casing lower left that are positioned at following saw blade clamper below, be positioned at upper left the 4th propelling sheave of casing and be positioned at the 5th propelling sheave above the saw blade clamper.5 propelling sheaves are installed on the casing with little axle respectively.The other end of short steel wire is walked around the 2nd and the 1st propelling sheave and is fixed on down on the saw blade clamper, and the other end of long steel wire is walked around the 3rd, the 4th propelling sheave, steel wire strainer and the 5th propelling sheave successively and is fixed on the saw blade clamper.
During work, motor rotating drives flywheel, little axle, roller, slide block and steel wire successively, the rotation of motor is converted to slide block and is in swinging of steel wire between the 2nd and the 3rd propelling sheave.In view of steel wire is tensioned, the swinging of steel wire that is between the 2nd and the 3rd propelling sheave driven to whole length steel wire, and after steel wire was repeatedly commutated, finally the saw blade that spurs between upper and lower saw blade clamper moved up and down, and has finished the sawing task.During sawing, the afterbody of upper and lower saw blade clamper is reciprocating along last lower guide channel respectively all the time.
The steel wire strainer by in the hole of passing above the casing and the knob of head band screw rod, with internal thread be installed in adjusting rod on the screw rod, be fixed on the adjusting rod end little axle, be installed in the regulating wheel on the little axle and be installed in the left regulating wheel and the right regulating wheel that are positioned at the regulating wheel both sides on the casing and formed with axle.
After saw blade is loosening, only need the rotation knob, knob just can drive adjusting rod and move up, and will move on the regulating wheel subsequently.So the steel wire that is clamped between regulating wheel and the left and right regulating wheel just is tensioned.This steel wire strainer is simple in structure, easy to adjust.Certainly, also can adopt other structure.Because adjusting rod is clamped in the middle of the casing, can not be rotated by knob during adjusting again, can only move up and down.
Casing can be made by the steel plate punching press.The casing processing technology that is stamped to form with steel plate is good, and production cost is low, and die cost is also low.The casing of aluminium alloy compression casting manufacturing is in the past compared, and its material, mould, the whole decline of processing cost have only 1/4～1/3 of the past.
Steel wire also can be steel wire rope.Steel cable has good intensity and toughness, and service life is also long.
The invention provides that a kind of transmission mechanism and component structural thereof are very simple, processing technology is improved greatly; Vibrations are little during work, noise is little, can not cause complete machine displacement, not only have been beneficial to environmental protection but also safe and reliable; The mould manufacturing expense is lower, the sweep-saw of the steel wire transmission that material and production cost reduce greatly.It can be widely used in the saw processing of light sheets such as plank.
