Abstract
The utility model discloses a keyway broach with adjustable broaching depth. The keyboard broach comprises a cutting edge and a cutter base, wherein the front end of the cutting edge is hinged with the cutter base; a hinged angle of the cutting edge and the cutter base is adjusted by a slide block which moves forwards and backwards along the cutter base; the tail end of the cutting edge is supported by the front end of the slide block; a slide block translation mechanism is arranged at the rear end of the slide block; the translation mechanism drives the slide block to move, so that the cutting edge rotates around the hinged point to adjust the broaching depth. The keyway broach with the adjustable broaching depth disclosed by the utility model is adjustable in depth, simple in structure, simple and convenient to operate.
Description
Technical field
The utility model relates to a kind of cutter, particularly a kind of for the adjustable keyway broach of the degree of depth of broaching.
Background technology
Broaching tool is the forming tool for broaching.On tool surface, have many row's cutters tooth, each size and dimension of arranging cutter tooth increases successively and changes to cutting out end from incision end.When broaching tool is done broaching motion, each cutter tooth just cuts certain thickness metal from workpiece, finally obtains desired size and dimension.Broaching tool is usually used in batch and in production, processes circular hole, splined hole, keyway, plane and profiled surface etc. in a large number, wherein keyway broach is the conventional a kind of cutter of processing keyway, the existing keyway broach broaching degree of depth is non-adjustable, cannot be suitable for the workpiece of different working depths, and blade wearing and tearing are after repairing a die, working depth is shoaled, cannot be suitable for former working depth.
For above-mentioned deficiency, need improve existing keyway broach, make its broaching degree of depth adjustable.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of degree of depth of broaching adjustable keyway broach, and the keyway broach that this broaching degree of depth is adjustable rotates by blade, thereby overcomes the deficiency of above-mentioned prior art.
The adjustable keyway broach of the broaching degree of depth of the present utility model, comprise blade and tool rest, described blade front end and tool rest are hinged, and blade and tool rest hinge angle are adjusted by being positioned at the slide block that can move forward and backward along tool rest on tool rest, slip front supports blade end, and slider tail arranges slide block translation mechanism.
Further, described slide block translation mechanism comprise be fixed on tool rest near the projection of slips end and and be screwed into the bolt of projection, the front end of bolt is connected with slips end.
Further, described projection is detachable connection with tool rest.
Further, on described bolt, screw thread is fine thread.
Further, described slider bottom arranges wearing plate.
Further, described wearing plate is connected with slide block is detachable.
Further, the surface of described slip front support blade is arc.
The beneficial effects of the utility model: the adjustable keyway broach of the broaching degree of depth of the present utility model, comprise blade and tool rest, described blade front end and tool rest are hinged, blade and tool rest hinge angle are adjusted by being positioned at the slide block that can move forward and backward along tool rest on tool rest, slip front supports blade end, slide block rear end arranges slide block translation mechanism, and it is the capable of regulating broaching degree of depth around its hinge rotation that translation mechanism drive slide block to move to make blade.The keyway broach broaching degree of depth that the utility model broaching degree of depth is adjustable is adjustable, simple in structure, easy and simple to handle.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the Facad structure schematic diagram of the utility model embodiment 1;
Fig. 2 is the Facad structure schematic diagram of the utility model embodiment 2.
The specific embodiment
Below with reference to accompanying drawing, the utility model is elaborated, as depicted in figs. 1 and 2: the adjustable keyway broach of the broaching degree of depth of the present embodiment, comprise blade 1 and tool rest 2, described blade front end and tool rest are hinged by bearing pin 6, blade tail support is on slide block 3, slide block 3 is driven and can be moved horizontally along tool rest by translation mechanism, and slide block moves horizontally and can drive blade to rotate around hinge, and then the adjustable keyway broach broaching degree of depth of the degree of depth that makes to broach is adjustable.
As the further improvement of technique scheme, described slide block 3 bottoms arrange wearing plate 3a, long service life
As the further improvement of technique scheme, described wearing plate 3a is arranged on slider bottom by soket head cap screw, after wearing plate wearing and tearing, is convenient to change
As the further improvement of technique scheme, the surface that described slip front supports blade is arc, contacts smooth.
With regard to slide block translation mechanism, be more convenient to understand below, enumerate following two kinds of specific embodiments:
Slide block translation mechanism in embodiment 1 comprises and is fixed on tool rest 2 near the projection 4 of slips end and is screwed into projection bolt 5, bolt 5 front ends are connected with slide block, stubborn bolt can make slide block translation, projection 4 is bolted on tool rest 2, being convenient to projection changes because of thread abrasion, in order to control slide block translation precision, be blade running accuracy, the screw thread on bolt 5 is made as to fine thread.
Slide block translation mechanism in embodiment 2 is the cylinder 6 that is fixed on close slips end on tool rest 2, and the piston end front end of cylinder 6 is connected with slide block, and the flexible of cylinder piston can be realized slide block translation.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
