A kind of metal cutter with dual rotary baffle plate
Technical field
With a metal cutter for dual rotary baffle plate, belong to a technical field of machine tools.
Background technology
Can sand loading wheel or alloy saw blade (hereinafter referred to as emery wheel) during metal cutter cutting different metal, having during its cutting metal that otch is neat, smooth, precision advantages of higher, is the requisite instrument of the industry such as machining, repair of machine.Existing metal cutter is equipped with the Simple clamp be made up of a sideboard and screw rod etc. on which bench.This sleeve clamp is contained in an avris of emery wheel, although it also can do the rotation of certain limit, but its pivot distance emery wheel is far away, so when adjust sideboard in case can cut out otch be less than the workpiece of an angle of 90 degrees time, baffle plate will depart from the cutting center of emery wheel with workpiece, if when adjustment angle is slightly large, workpiece can deviate from the cut coverage of emery wheel and cannot cut.This is because the pivot of the baffle plate of existing metal cutter is not below the center (axial centre) of emery wheel two plane.Simultaneously because its fixture has been contained in an avris of emery wheel, when shorter workpiece will be cut, such as one long be the work piece cut of 3 centimeters open time, due to can be little for the surplus of clamping, even cannot carry out so cutting work will become very difficult.Fact proved that existing metal cutter does not possess the ability of low-angle otch and cutting casual labourer part substantially.But cutting low-angle otch and cutting casual labourer part often use in machining and repair of machine work, existing cutting machine in this respect can not, greatly restrict its range of application, also make troubles to mechanic.
Patent of invention number is that the technical scheme of ZL2012100670644 can solve the problems of the technologies described above well and be subject to favorable comment widely, but the installation site of the column cap in the program 6 and column sleeve 8 is just in time in the cutting working range of emery wheel, therefore when workman maybe will cut larger workpiece because of carelessness, and when needing emery wheel to cut the larger degree of depth, be easy to a column cap 6 and column sleeve 8 is cut brokenly.Cause machine breakdown.Avoid the generation of this situation must improve this patented technology.
Summary of the invention
For overcoming the metal cutter that the existing patent No. is ZL2012100670644, because of the larger workpiece of cutting, when needing emery wheel to cut the larger degree of depth, easily column cap 6 and column sleeve 8 being cut brokenly, causing the shortcoming of machine breakdown.The present invention takes following technical measures: two lugs 9 that it mainly comprises emery wheel 1, workbench 2, cylindrical drum 6, T-shaped right baffle-plate 3, the right baffle plate of T-shaped, deep-slotted chip breaker 11, column sleeve 8 and is contained in above it.The lower work platform 2 of emery wheel 1 central plane processes deep-slotted chip breaker 11 and processes in the inner side of deep-slotted chip breaker 11 or cylindrical drum 6 is installed, cylindrical drum 6 is installed column sleeve 8, column sleeve 8 is processed with lug 9, the right baffle plate of T-shaped right baffle-plate 3, T-shaped 4 to be contained on two lugs 9 of column sleeve 8 through deep-slotted chip breaker 11 and to overlap with the diameter line on column sleeve 8.
The good outer of the structure that this programme is such is that the column sleeve 8 of T-shaped right baffle-plate 3, the right baffle plate 4 of T-shaped is housed, and be enclosed within cylindrical drum 6, column sleeve 8 is free to rotate, is convenient to metal cutter and cuts out low-angle workpiece.Cylindrical drum 6 is hollow, and it is in fact an annulus.Such structure just in time leaves the space of work to emery wheel, overcome the metal cutter that the patent No. is ZL2012100670644, when needing emery wheel to cut the larger degree of depth cutting larger workpiece, easily column cap 6 and column sleeve 8 is cut brokenly the shortcoming causing machine breakdown.

In figure: 1 emery wheel, 2 workbench, 3 right baffle-plates, 4 right baffle plates, 5 fastening turn-knobs, 6 column casings, 7 emery wheel grooves, 8 column sleeves, 9 lugs, 10 studs, 11 deep-slotted chip breakers, 12 column sleeve holes.
Detailed description of the invention
The patent No. is the metal cutter of ZL2012100670644, structurally has the shortcoming that very large, is exactly that its column cap 6 is just in time in the scope of activities of the cutting work of emery wheel.When needing when the larger workpiece of the confidential cutting of Metal Cutting emery wheel to cut the larger degree of depth, easily column cap 6 is cut brokenly together with column sleeve 8 and cause machine breakdown.Address this problem, column cap 6 must be taken away, leave the activity space of work to emery wheel 1.But taking away that column cap 6 just means will again for left baffle provides movable support platform.For this reason, the present invention takes following structure.The lower work platform 2 of emery wheel central plane processes deep-slotted chip breaker 11 and processes in the inner side of deep-slotted chip breaker or cylindrical drum 6 is installed, cylindrical drum 6 is installed column sleeve 8, column sleeve 8 is processed with lug 9, the right baffle plate of T-shaped right baffle-plate 3, T-shaped 4 to be contained in by bolt through deep-slotted chip breaker 11 on two lugs 9 on column sleeve 8 and to overlap with the diameter line on column sleeve 8, as shown in Figure 1, Figure 2 and Figure 3; Because cylindrical drum 6 itself is hollow, the good activity space leaving work to emery wheel under its this feature.Solve the metal cutter of ZL2012100670644 operationally, likely damage the deficiency of column cap 6.Such structure be exactly be contained in cylindrical drum 6 with column sleeve 8 outside equally can flexible rotating to cut low-angle workpiece, column sleeve 8 has a column sleeve hole 12, the correspondence position of cylindrical drum 6 is processed with an internal thread hole, fastening turn-knob 5 and stud 10 are fitted together, and stud 10 are processed with a step for compressing column sleeve 8.Stud 10 is threaded with cylindrical drum 6 with screwed hole through in column sleeve hole 12.Adjusting fastening turn-knob 5 can fastening column sleeve 8.Gu the column cap 6 that column sleeve 8 substitutes in the metal cutter of ZL2012100670644 provides support for T-shaped right baffle-plate 3 and the right baffle plate 4 of T-shaped.
Cylindrical drum 6 in addition in the application and the status between column sleeve 8 can exchange.Such as column sleeve 8 is installed with on workbench, the chi of change cylindrical drum 6 is crossed and is made it can put into column sleeve 8, and lug 9 is contained in column sleeve 8.The effect of such gained is the same.
