Description
Technical field
The utility model relates to a kind of diagonal cutting saw, especially relates to a kind of structural improvement of the two-way diagonal cutting saw that cuts of cutting sth. askew that can swing.
Background technology
Diagonal cutting saw has very wide range of application as a kind of cutting tool, can be used to cut a lot of metals or nonmetallic materials, cuts efficient and convenient.When the cutting material, hold diagonal cutting saw operation handle, make saw blade towards lopsidedness, thereby realizing cutting sth. askew cut.At present, the saw blade of widely used diagonal cutting saw all can only be towards a direction swing, this type of diagonal cutting saw all is greatly improved on the job stability in machining accuracy, has all obtained application in a lot of industries, but, the bigger defective of its same existence: owing to can only swing towards a direction, thereby the scope of its cutting is less, it is very not convenient to use, limit the scope of application of diagonal cutting saw greatly, can't satisfy different users's requirement.In actual mechanical process, increased operator's labour intensity, operating efficiency is very not high.In addition, general be provided with vertical with saw blade of the drive motors of diagonal cutting saw transmission mechanism so also limited the bidirectional swinging of diagonal cutting saw at present.In case saw blade is when being equipped with a side oscillation of drive motors, the shell of its drive motors just collides with the cross bar of being located on the base easily, causes it to work smoothly.
Summary of the invention
The utility model mainly is to solve existing in prior technology can only swing towards a direction, and the scope of cutting is less, uses operation inconvenience, the technical problem that operating efficiency is not high.
The utility model has solved be provided with vertical with saw blade of existing in prior technology drive motors simultaneously again and has caused its shell to collide the technical problem that the stability during work is very not high with the cross bar of being located on the base easily.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: bilateral swing type diagonal cutting saw, comprise support, head-shield, be located at the saw blade in the head-shield, the operation handle that links to each other with head-shield, and be located at guide rail on the base, it is characterized in that linking to each other with Connection Block by connecting axle at described support; Described support is provided with the support boss, is respectively equipped with angle-adjusting mechanism in the both sides of Connection Block.The utility model creatively diagonal cutting saw is designed to can bilateral the form of swing, and set the amplitude that swings by angle-adjusting mechanism.Thereby fundamentally overcome existing diagonal cutting saw and can only enlarge the scope of application of diagonal cutting saw effectively to the shortcoming of lopsidedness, made things convenient for user's operation.The amplitude of swinging here can be set lower dead center by angle-adjusting mechanism.According to actual needs, left and right sides lower dead center can be arranged to symmetrical, also can be asymmetric.
In use, diagonal cutting saw when tilting because the gravity effect, support and head-shield can be swung to left side or right side suddenly, in order to address this problem, as preferably, described Connection Block is provided with reference column, is with torsion spring on reference column, and the bipod of described torsion spring is located at the both sides of support boss respectively; Be provided with the Connection Block boss between the bipod of described torsion spring.On a left side or to the right in the swing process, the bipod of torsion spring contact with the Connection Block boss with the support boss respectively, thereby the generation resistance has solved this problem effectively.And, be convenient to after being used to complete cut and reset to the upright position from cutting sth. askew.
As preferably, the connecting portion of described support and Connection Block is provided with the angle orientation sheet, is provided with a steel ball hole on the described angle orientation sheet at least; Described Connection Block is provided with and the corresponding spacing hole in steel ball hole, is provided with spring and steel ball in it.Like this, when saw blade was positioned at the upright position, steel ball headed into the steel ball hole in the effect next part of spring, thereby played the effect of location.During use, need exert oneself a little, make steel ball break away from the steel ball hole, thus easy to use.The number in steel ball hole can be determined according to actual needs.
As preferably, described angle-adjusting mechanism system is made up of angle adjustable bolt and matched with it adjusting nut; The described axle system of connecting is by connecting bolt and the matched with it nut that connects is formed.During use, angle adjustable bolt is pushed up mutually with the support boss, thereby determines the following angle of ending of this side.Adjusting angle is regulated the length of bolt can adjust down the only size of angle at any time.Connect bolt and determine the tightness that support is swung with the tightness that connects nut.
As preferably, a side of described head-shield is provided with drive motors, and the machine shaft of described drive motors is provided with active oblique gear, and described active oblique gear is meshed with driven helical gear, and described driven helical gear is matched by output revolving shaft and saw blade.By helical gear the vertical setting with saw blade of existing driving mechanism is changed into and to be obliquely installed, like this with regard to the shell that solved drive motors with regard to easily be located at the problem that the cross bar on the base collides.
As preferably, the axis of described machine shaft and the axis of active oblique gear overlap, the plane γ in an acute angle at the axis of described machine shaft and saw blade place, and the size at described γ angle is 30 °～60 °.In order to guarantee helical gear intensity, the size at γ angle is both unsuitable excessive also unsuitable too small here.
Equally, in order to guarantee the intensity of transmission mechanism, the amplitude of fluctuation of diagonal cutting saw is also unsuitable excessive, and as preferably, the maximum angle of described support skew perpendicular both sides is 60 °.
In addition, as preferably, described support is provided with angle indicator; Described Connection Block is provided with the scale that cooperates with angle indicator.Angle indicator and scale are set to be convenient to accurately locate in the process super the work.
Therefore, the utlity model has following advantage: 1, reasonable in design, simple in structure, effect is obvious; 2, transmission mechanism and saw blade are obliquely installed, and shell is difficult for and the cross bar collision of being located on the base; 3, effectively realize the bilateral swing work of diagonal cutting saw, enlarged range of application; 4, improve work efficiency, and guaranteed the accuracy of processing, improved machining accuracy; 4, easy to operate, safe, reliable, steady, reduced labour intensity.
