The specific embodiment
Below in conjunction with drawings and Examples the utility model being further described, is " the place ahead " described in this specification clockwise in the accompanying drawing 2, is " rear " described in this specification counterclockwise in the accompanying drawing 2.The arrow direction is " the place ahead " described in the specification in the accompanying drawing 3.
Accompanying drawing 1 to accompanying drawing 9 is embodiment one of the present utility model, and it discloses a kind of multi-knife-head grooving tool, comprises the first cutterhead 10 and second cutterhead 20 of mutual amalgamation and is installed in a plurality of cutter heads 30 between described the first cutterhead 10 and the second cutterhead 20.
Offer a plurality of the first cutter grooves 101 that roughly radially extend on described the first cutterhead 10, the first cutterhead 10 between a plurality of described the first cutter grooves 101 forms a plurality of the first limited sections 102, offer the second cutter groove 201 on described the second cutterhead 20, the second cutterhead 20 between a plurality of described the second cutter grooves 201 forms a plurality of described the second limited sections 202, and after described the first cutterhead 10 and 20 amalgamations of the second cutterhead, described the first limited section 102 is at least part of stretches in described the second cutter groove 201 the front side wall 106 of described the first limited section 102, the part groove bottom of the rear side wall 205 of described the second limited section 202 and described the first cutter groove 101 and the second cutter groove 201 forms the receiving space of accommodating described cutter head 30.Offer respectively installing hole 107 on described the first cutterhead 10 and the second cutterhead 20, be provided with the clamping screw (not shown) that runs through described the first cutterhead 10 and the second cutterhead 20 in the described installing hole 107.Can be with the first cutterhead 10 and the second cutterhead 20 quick lockings by clamping screw, and clamping cutter head 30, after long-time use, can unclamp clamping screw, the first cutterhead 10 and the second cutterhead 20 are taken apart, and take out the cutter head 30 of damage, the cutter head 30 that more renews and do not need to change whole cutter, in addition, this structure can be convenient to equally to take out cutter head 30 and keep in repair or grinding, and the grinding rear blade can continue to utilize.
The front side wall of the rear side wall of described the first limiting section 102 and described the second limiting section 202 has respectively mutually the first inclined-plane 105 and second inclined-plane 203 of compression fit, described the first inclined-plane 105 extends near the direction of the second cutterhead 20 to forward direction gradually from the middle part of the rear side wall of described the first limiting section 102, and the second inclined-plane 203 extends towards backward direction near the first cutterhead 10 from the front side wall of the second limiting section 202.The first inclined-plane 105 and the second inclined-plane 203 are set the first cutterhead 10 and the second cutterhead 20 are compressed when amalgamation all the time, thus fastening cutter head 30.
Too concentrated for preventing that cutter head 30 from stretching out the shearing force that the part of cutterhead bears, the projection 103 that also has the outer circumference surface that protrudes from described the first cutterhead 10 on described the first limiting section 102, projection 103 stretches out from the first limiting section 102, and on the perspective plane perpendicular to the center of rotation of described cutterhead, described projection 103 is fan-shaped.Described projection 103 is against the rear of described cutter head 30, and when the cutter rotation was cut, projection 103 was against bearing part, the rear shearing force of cutter head 30.
For preventing that cutter head 30 breaks away from cutterhead.Have on the described cutter head 30 along the axially extended boss 302 of described the first cutterhead 10, offer a plurality of spacing holes 109 that can accommodate described boss 302 on described the first cutterhead 10, described boss 302 is stuck in the described spacing hole 109.A plurality of spacing holes 109 roughly radially are distributed in described the first cutter groove 101, therefore, and after cutter head 30 is carried out grinding, cutter head 30 shortens, and it outwards can be arranged accordingly, and boss 302 is connected in the spacing hole 109 in the outside, therefore repeatedly grinding of this cutter head is reused.
Say that further the formation material of described cutter head 30 is carbide alloy.The formation material of described the first cutterhead 10 and the second cutterhead 20 is stainless steel.
Drainage for ease of the cutting chip, with to prevent cutter head overheated, also offer the guiding gutter 108 that multiple tracks is roughly radially extended on the outer surface of described the first cutterhead 10 and the second cutterhead 20, among the embodiment one, this guiding gutter 108 is radially dispersed outside the mediad of cutterhead, guiding gutter 108 can increase the surface area of cutterhead, causes Air Flow, and the heat that produces in the working angles is distributed rapidly.
Accompanying drawing 11 is embodiment two of the present utility model, the difference of itself and embodiment one is: also offer multiple tracks on the outer surface of described the first cutterhead 10 and the second cutterhead 20 and roughly be the guiding gutter 108 and 204 that vortex shape extends from inside to outside, Vorticose guiding gutter has better chip removal and radiating effect.
Accompanying drawing 12 is embodiment three of the present utility model, the difference of all the other embodiment one is: offer the louvre 104 that a plurality of and described the first cutter groove 101 or the second cutter groove 201 are connected on the outer surface of described the first cutterhead 10 and/or described the second cutterhead 20, the heat that this louvre can distribute cutter head 30 is rapidly derived.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
