Description
Technical field
The utility model relates to a kind of protector of electric cutting tool, is specifically related to a kind of protector of bench saw.
Background technology
At present, bench saw is used widely in field of machining and machinebuilding technology, can be used to materials such as cutting panels of wood, plastic plate, composite plate and metallic plate.But bench saw in the course of the work, the saw blade material to be cut occurs through regular meeting and tightly bite and out-of-work phenomenon, if untimely deenergization also can burn motor.At this problem, install feeding-distribution device additional on some bench saw, in cutting process cutting section is reduced greatly to the snap-in force of saw blade.But the setting height(from bottom) of this kind feeding-distribution device is fixed, and the processing to material comprises cut-out, do not cut off or multiple mode such as fluting, so existing feeding-distribution device can not satisfy the requirement of multiple processing in the course of work.Simultaneously, the accident that material bounce-back and sawdust fly out and hurt sb.'s feelings takes place in existing bench saw easily in cutting material process, and these problems all need to be resolved hurrily.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model proposes and a kind ofly can regulate sub-material knife up degree, and the protector of the bench saw that can effectively avoid material bounce-back and sawdust to fly out hurting sb.'s feelings.
Technical scheme: for solving the problems of the technologies described above, the protector of bench saw of the present utility model comprises sub-material cutter, protective cover and retaining sheet, and described sub-material cutter is provided with gathering sill and locating hole; The sub-material cutter is located at the back of saw blade and is connected with the axle of motor by supporting seat; The upper end of sub-material cutter is connected with retaining sheet with protective cover respectively.
Wherein, the sub-material cutter is installed on the supporting seat by handling knob, handle knob and the sub-material cutter between be provided with sub-material cutter pressing plate, sub-material cutter pressing plate is provided with the locating shaft that can slide in gathering sill; Described supporting seat is provided with dowel hole, and the hole that sub-material cutter alignment pin passes on dowel hole, the locating hole on the sub-material cutter and the sub-material cutter pressing plate on the supporting seat successively positions the sub-material cutter; The sub-material cutter alignment pin outside is provided with adjusting rod.
Described locating hole has 3, lays respectively at the position, upper, middle and lower of sub-material cutter.Like this, can as required the sub-material cutter be fixed on extreme higher position, centre position and extreme lower position.
Described protective cover comprises guard shield body and guard shield supporting seat, and the guard shield body is movably arranged on the guard shield supporting seat, and the guard shield supporting seat is connected with the sub-material cutter by first connecting axle, and first connecting axle, one side is provided with briquetting and is used to push first rotary spanner of briquetting.Described retaining sheet comprises retaining sheet body and retaining sheet supporting seat, the retaining sheet body is movably arranged on the retaining sheet supporting seat, the retaining sheet supporting seat is connected with the sub-material cutter by second connecting axle, and second connecting axle, one side is provided with briquetting and is used to push second rotary spanner of briquetting.
The utility model is divided into following three kinds of situations in use:
When material is normally cut, need be installed in the extreme higher position to the sub-material cutter, be about to the locating hole that sub-material cutter alignment pin inserts sub-material cutter bottom, tighten again and handle knob, the sub-material cutter is fixed on the supporting seat, protective cover and retaining sheet is installed in the upper end of sub-material cutter respectively.In the process of cutting material, along with pushing ahead of material, material promotes the circular arc limit of protective cover, protective cover is upset upwards, material continues to push ahead by the saw blade cutting processing, so protective cover can either play the effect of security protection, can not influence the smooth processing of material again.
When material processing request material is not cut off, need be installed in the centre position to the sub-material cutter, be about to sub-material cutter alignment pin and extract from the locating hole of sub-material cutter bottom, be inserted into the locating hole of sub-material cutter middle part again.At first need to disassemble protective cover and retaining sheet, as long as rotate first rotary spanner respectively and second rotary spanner just can remove protective cover and retaining sheet from the sub-material cutter like a cork.Then, unclamp and handle knob, stir adjusting rod, sub-material cutter alignment pin moves the dowel hole that breaks away from the supporting seat round about, the sub-material cutter is moved down again, and sub-material cutter alignment pin is inserted the locating hole of sub-material cutter middle part, tighten again and handle knob, the sub-material cutter is fixed on the supporting seat.
When material processing request material is just slotted, need be installed in extreme lower position to the sub-material cutter, be about to sub-material cutter alignment pin and extract from the locating hole at sub-material cutter middle part, be inserted into the locating hole on sub-material cutter top again.Because the existence of locating hole makes the adjusting of sub-material knife up degree flexible, can satisfy the requirement of different processing tasks.
Beneficial effect: the protector of bench saw of the present utility model is skillfully constructed, simple in structure, the height of flexible modulation sub-material cutter as required, and can effectively avoid material bounce-back and sawdust to fly out and hurt sb.'s feelings, working (machining) efficiency and enhancing processing safety can be improved.
