Description
Technical field
The utility model relates to the cutting machine technical field, especially relates to a kind of movable backer's device of cutting machine.
Background technology
Cutting machine has very wide range of application as a kind of cutting tool, can be used for a lot of metals of cutting or nonmetallic materials, cuts efficient and convenient.Usually the workbench at cutting machine arranges backer's structure, when material cuts, plays the effect of firm and definite cutting angle, and the backer just more can cut narrower workpiece the closer to saw blade.In the moment that workpiece soon cuts off and do not have to cut off, especially when firmly cutting, the very big impulse force that cuts is forward arranged in the cutting process in addition, workpiece difficulty is controlled firmly, and the backer is the closer to the saw blade heartcut, and the impulsive force in the time of will cutting off shortly just more can be overcome by the backer, cuts just safer.But the most structure of backer of the prior art is thick and heavy, for cutting machine is not interfered with the backer when head is cut sth. askew, its backer must be away from saw blade, thereby is difficult to satisfy normal split requirement when the narrower workpiece of cutting, be cut workpiece by putting instability, occur dangerous easily.The day for announcing is on November 29th, 2006, notification number is that the Chinese patent file of CN2841216Y discloses a kind of diagonal cutting saw backer structure, comprise backer's main body, it is characterized in that backer's slide block that installation is slidingly matched on backer's main body or the backer who is rotationally connected turn over piece, during thicker material, load onto backer's slide block in cutting, or backer's slide block to intermediate flipped, increase backer's height, guarantee that material is stable when cutting; When cutting thin material, unload backer's slide block or backer's slide block is routed up the outside, then when cutting, different angles just can not touch with backer's structure, and avoid potential safety hazard, and satisfied the cutting needs of thickness different materials.But this this structure is adjusted backer's complex operation when carrying out the cutting operation of different workpieces, and backer's self structure complexity, and cost is very high.
The utility model content
The utility model for the cutting machine that solves prior art since the backer away from saw blade, thereby occur dangerous problem when being difficult to cut narrower workpiece and cutting easily and provide a kind of backer close to cast-cutting saw slice, can cut movable backer's device of narrower workpiece, cutting machine that security is good.
The utility model is to reach the concrete technical scheme that above-mentioned technical purpose adopts to be: a kind of movable backer's device of cutting machine, described cutting machine comprises support and head, support is provided with workbench, fixedly backer is installed on the workbench, cast-cutting saw slice is installed on the head, be connected with the movable backer that can move with respect to fixing backer the fixedly backer of workbench, the rectangular platy structure of described movable backer, movable backer is provided with the chute parallel with rectangular slab one side, fixedly the backer is provided with movable backer's fixing hole, movable backer and fixedly being connected and fixed by bolts and nuts between the backer.Fixing backer movable backer is set, when the narrower workpiece of needs cutting, movable backer can be fixed to cast-cutting saw slice one side shifting and in the appropriate location near cast-cutting saw slice, can cut.Otherwise, when the wideer workpiece of cutting does not need backer and cast-cutting saw slice to lean on closely excessively, or movable backer and cast-cutting saw slice lean on closely easily and are cut off when cutting sth. askew, can be with movable backer to also in position fixing away from cast-cutting saw slice one side shifting, movable backer just can not cause adverse effect to cutting, the utility model adopts the cooperation of bolts and nuts to fix movable backer, have simple in structure, convenience operation.
As preferably, chute is rectangular channel, rectangular channel is arranged on the one side of movable backer away from fixing backer, the bottom land of rectangular channel is provided with a Long Circle through hole, described bolt is square head bolt, the head of square head bolt fits in the rectangular channel, and the screw rod of square head bolt passes the Long Circle through hole of bottom land and the fixing fixing hole on the backer, and described nut is the wing nut that is arranged on the square head bolt afterbody.Adopt the fixing movable backer of wing nut, have simple in structurely, tighten and unclamp characteristics efficiently, handled easily the workman enhance productivity.Chute also can adopt two kinds of following versions:
1, chute is T-slot, T-slot is arranged on the one side that movable backer is close to fixing backer, described bolt is square head bolt, the head of square head bolt fits in the T-slot, the screw rod of square head bolt passes the fixing hole on the fixing backer, and described nut is the wing nut that is arranged on the afterbody of square head bolt.
2, chute is dovetail groove, dovetail is arranged on the one side that movable backer is close to fixing backer, described bolt is dormant bolt, the head of dormant bolt fits in the dovetail groove, the screw rod of dormant bolt passes the fixing hole on the fixing backer, and described nut is the eyenut that is arranged on the afterbody of dormant bolt.
The chute of these two kinds of structures all is arranged on the one side that movable backer is close to fixing backer, and the contact-making surface of so movable backer and workpiece is a complete plane, is conducive to improve the precision that reclines.
As preferably, the chute both sides on the movable backer are provided with the loss of weight groove parallel with chute, and described loss of weight groove is arranged on the one side that movable backer is close to fixing backer.
As preferably, movable backer is rectangular plate, and the width of rectangular slab is identical with fixing backer's height, and chute is arranged on the length direction of rectangular plate.The movable backer of this structure can be used as fixedly backer's extending structure in the horizontal direction, also movable backer vertically can be placed as the fixing extending structure of backer on short transverse, can adapt to different processing needs.
As preferably, nut and fixedly be provided with stage clip between the backer.At nut and stage clip fixedly is set between the backer can prevents movable backer and fixing being connected cutting machine when work and becoming flexible because of vibrations of backer.
The beneficial effects of the utility model are: it solved effectively prior art cutting machine since the backer away from saw blade, thereby dangerous problem appears when being difficult to cut narrower workpiece and cutting easily, of the present utility model simple in structure, it is stable to cut narrower workpiece, work safety, has very high practical value.
