Improvement with the metal cutter of dual rotary baffle plate
Technical field
With the metal cutter of dual rotary baffle plate, belong to a technical field of machine tools.
Background technology
Can sand loading wheel or alloy saw blade (being designated hereinafter simply as emery wheel) during metal cutter cutting different metal, have during its cutting metal that otch is neat, smooth, the precision advantages of higher, be the requisite instruments of industry such as machining, repair of machine.Existing metal cutter is equipped with the simple and easy fixture consisted of a sideboard and screw rod etc. on its workbench.This sleeve clamp is contained in an avris of emery wheel, although it also can do the rotation of certain limit, but its pivot is far away apart from emery wheel, so when adjusting sideboard so that can cut out otch and be less than the workpiece of an angle of 90 degrees the time, baffle plate will depart from workpiece the cutting center of emery wheel, if, when the adjustment angle is slightly large, workpiece can depart from the cut coverage of emery wheel and can't cut.This is that pivot because of the baffle plate of existing metal cutter is not below the center on emery wheel two planes (axial centre).Due to its fixture, be contained in an avris of emery wheel simultaneously, when cutting shorter workpiece, for example one long be the work piece cut of 3 centimeters while opening, owing to can for the surplus of clamping seldom, even carrying 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.Yet cutting low-angle otch and cutting casual labourer part are often to use in machining and repair of machine work, existing cutting machine in this respect can not, greatly restrict its range of application, also to mechanic, make troubles.
Patent of invention number can solve the problems of the technologies described above and be subject to favorable comment widely well for the technical scheme of ZL2012100670644, but the installation site of the column cap 6 in this scheme and column sleeve 8 is just in time in the cutting working range of emery wheel, therefore work as the workman and maybe will cut larger workpiece because of carelessness, and while needing the larger degree of depth of emery wheel incision, be easy to a column cap 6 and column sleeve 8 is cut brokenly.Cause machine breakdown.Avoid the generation of this situation to be improved 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, while needing the larger degree of depth of emery wheel incision, easily column cap 6 and column sleeve 8 are cut brokenly, cause the shortcoming of machine breakdown.The present invention takes following technical measures: process deep-slotted chip breaker 11 on workbench 2 and process or install cylindrical drum 6 in the inboard of arc groove below emery wheel 1 central plane, column sleeve 8 is installed on cylindrical drum 6, be processed with lug 9 on cylindrical sleeve 8, the right baffle plate 4 of T shape right baffle-plate 3, T shape through deep-slotted chip breaker 11, be contained on two lugs 9 of column sleeve 8 and with vertical coincidence of diameter line on column sleeve 8.
The good outer of the structure that this programme is such be, the column sleeve 8 of T shape right baffle-plate 3, the right baffle plate 4 of T shape is housed, and is enclosed within on cylindrical drum 6, and 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 stays the space of work to emery wheel, the metal cutter that to have overcome the patent No. be ZL2012100670644, while at the larger workpiece of cutting, needing the larger degree of depth of emery wheel incision, easily cut brokenly the shortcoming that causes machine breakdown to column cap 6 and column sleeve 8.

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 double-screw bolts, 11 deep-slotted chip breakers, 12 column sleeve holes.
The specific embodiment
The metal cutter that the patent No. is ZL2012100670644, structurally have a very large shortcoming, is exactly that its column cap 6 is just in time in the scope of activities of the cutting work of emery wheel.While needing the larger degree of depth of emery wheel incision when the larger workpiece of the confidential cutting of Metal Cutting, easily column cap 6 is cut brokenly and caused machine breakdown together with column sleeve 8.Address this problem, must take column cap 6 away, in order to stay the activity space of work to emery wheel 1.But, take away column cap 6 and just mean and will again for left baffle, provide movable support platform.For this reason, the present invention takes following structure.Process deep-slotted chip breaker 11 on workbench 2 and process or install cylindrical drum 6 in the inboard of arc groove below the emery wheel central plane, column sleeve 8 is installed on cylindrical drum 6, be processed with lug 9 on cylindrical sleeve 8, the right baffle plate 4 of T shape right baffle-plate 3, T shape through deep-slotted chip breaker 11, by bolt, be contained on two lugs 9 on column sleeve 8 and with vertical coincidence of 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 that stays work to emery wheel under its these characteristics.Solve the metal cutter of ZL2012100670644 when work, likely damaged the deficiency of column cap 6.But such structure is exactly to be contained in the same flexible rotating in outside of cylindrical drum 6 so that cutting low-angle workpiece with column sleeve 8, have a column sleeve hole 12 on column sleeve 8, the correspondence position of cylindrical drum 6 is processed with an internal thread hole, fastening turn-knob 5 and double-screw bolt 10 are fitted together, and are processed with a step on double-screw bolt 10 for compressing column sleeve 8.Double-screw bolt 10 is through being threaded with cylindrical drum 6 with screwed hole in column sleeve hole 12.Adjusting fastening turn-knob 5 can fastening column sleeve 8.Gu the column cap 6 in the metal cutter of column sleeve 8 alternative ZL2012100670644 provides support for T shape right baffle-plate 3 and the right baffle plate 4 of T shape.
Status between cylindrical drum in the application 6 and column sleeve 8 can exchange in addition.For example 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 sons.The effect of gained is the same like this.
