Description
Technical field
The invention is related to a kind of electric cutting tool, and particularly one kind can be in bench saw operating mode and diagonal cutting saw work
The compound saw changed between operation mode.
Background technology
Composite saw is widely used in the fields such as machine-building as a kind of common electric tool.Compound saw can be oblique
Power and energy is carried out between disconnected saw and two kinds of working statuses of bench saw, it is very easy to use.There are common two kinds in the prior art
Scheme：A kind of scheme is common compound saw structure, typically fixes the height of motor and saw blade, is made by regulating platform cut
The height of platform come realize bench saw cutting function；It is motionless that another scheme is that platform cuts worktable panel, passes through lifting or electric rotating
Thermomechanical components realize the lifting of saw blade, the function cut so as to fulfill platform.
Two above scheme all existing defects in use.First scheme cuts the process of height of table in regulating platform
In, the relative position that platform is cut between worktable panel and saw blade can change, in order to ensure smooth, the Guiding machine of height adjusting
Structure generally there are larger gap, keeps the stability of relative position poor, greatly reduces platform and cut precision.Because motor and saw blade
Relative position it is motionless, so the thickness on the vertical direction of motor determines Tai Qie and beveling cutting power in height；
Electric machine assembly can be made very flat by actually most of producer, and so can somewhat improve that platform cuts and chamfer cuts height, still
It is highly detrimental to the design of motor and motor casing.
Alternative plan have two kinds by elevating mechanism come lifting motor component, first, motor vertical lifting or along motor
Fulcrum rotation oscilaltion outside component, the principle of this up-down mode is similar with first scheme, simply with the fortune of motor
The dynamic movement instead of platen；It is opposite when can improve lifting to a certain degree because the machining accuracy of the guiding of motor lifting ensures
Precision, but there is electric machine assembly thickness effect cutting power the problem of；In addition, the elevating mechanism of motor also can be big
The earth increases the complexity of mechanism.Second, electric machine assembly integrally curls up motor center rotation, gear-driven centre-to-centre spacing is utilized
The bias of formation is cut to switch beveling and platform, a kind of compound saw as disclosed in Chinese patent CN205020940, because motor needs
Rotation, so the whole rotating track of motor shape is round, so will increase relative to conventional flat electric machine assembly
The height of complete machine, the increase of packaging volume not only influence whether cost of transportation but also can influence the space of storage.It is and this
The output shaft and gear of structure can be only positioned at motor it is cylindrical within, eccentric distance is limited, and eccentricity determines saw blade from platen
Go out the maximum height to above platen, enough lifting spaces can not be provided, so as to limit cutting power.In order to expand cutting
Ability can only expanded motor shape circle, so again the machine dimensions can be caused excessive, and need to improve and support electric machine assembly
Rack construction mechanical performance, is also exactly that motor may cause the winding of power supply inlet-outlet line, abrasion equivalent risk in rotary course.
No matter that scheme is used, the saw blade of the non-active area of existing technical solution is exposed, to accomplish to protect completely
All it is difficult to control, the non-active area is non-active area during cutting on table, below platen, the right and wrong above platen in beveling
Working region, according to safety requirements, the sawtooth of non-active area will be accomplished to protect completely.So, it is common practice in non-work
Make region increases extra shield to be protected in the form of annex, it is also necessary to take particular form prevent annex lose or
Give it up, it is complicated and inconvenient.
In view of the above-mentioned problems, many manufacturers and knowledgeable people are developed and developed, but there has been no more satisfactory so far
Product emerge.
The content of the invention
To overcome drawbacks described above existing for existing compound saw, the purpose one of the invention is to solve to provide a kind of structure letter
List is rationally, power and energy operation is flexibly light, safe and reliable, cutting power is big, cutting accuracy is high, dust discharge effect is good answers
Formula is sawed.
The invention solves technical solution used by above-mentioned technical problem, it is provided with platform including top and cuts workbench

Box assembly can be rotated around motor gear axis, and saw blade is fixed on the output shaft of transmission mechanism, and output shaft and motor gear axis are mutual
It is parallel.
The further scheme of the invention, the gear housing are equipped with turning set, and rack is equipped with to be turned with turning set
The dynamic rotation seat coordinated.
The further scheme of the invention, the gear housing are equipped with conversion shield, and conversion shield is located at during beveling
The top of saw blade, changes shield and is located in the lower section of saw blade during cutting on table.
The further scheme of the invention, the central axle sleeve of the rotation seat are equipped with the gear box fastener that can mutually rotate
Plate and rack buckle, rack buckle are fixed in rack and block gear-box buckle, and gear-box buckle is fixed on gear housing
And block rack buckle.
The further scheme of the invention, the rack are equipped with the retaining mechanism of lock gear box assembly, lock machine
Structure includes locking wrench, locking pressure plate, and locking wrench is connected with each other through rack and locking pressure plate, and locking pressure plate is pressed from both sides by rack
Tight gear housing.
The further scheme of the invention, the both sides of the saw blade are correspondingly provided with the left and right shield fixed with rack, its
Rear portion is equipped with dust passage, is equipped between the shield of left and right and leads dirt loose-leaf board, changes shield during cutting on table by leading dirt loose-leaf board and collection
