The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of disposable valve pocket baseline trough process tool machining of valve pocket datum hole that makes.
For achieving the above object and other relevant objects, the utility model provides a kind of valve pocket baseline trough process tool, comprise a main milling cutter, the outer peripheral face of described main milling cutter is provided with several main cutting edges, the both sides of described main milling cutter are respectively provided with a side mill, two side mills are symmetrical arranged, described side mill is coaxially fixedly connected with described main milling cutter, the circle diameter of described side mill is less than the circle diameter of described main milling cutter, the outer peripheral face of described side mill is provided with several side cutting edges, the described side cutting edge certain angle that is inclined upwardly from inside to outside.
Preferably, described side cutting edge is inclined upwardly 30 °, 45 ° or 60 ° from inside to outside.
Preferably, two end faces of described main milling cutter are provided with draw-in groove, and the inner side end of described side mill is provided with projection, and described projection and described draw-in groove shape adapt, and described projection is connected in described draw-in groove.
Preferably, the width of described main cutting edge, side cutting edge is less than 20mm.
Preferably, described main cutting edge, side cutting edge are straight-tooth blade.
As mentioned above, valve pocket baseline trough process tool of the present utility model has following beneficial effect: this valve pocket baseline trough process tool is used three knife combinations, at the baseline trough on valve pocket, add man-hour, first by main milling cutter, valve pocket is cut, when main milling cutter is cut to after certain depth, the side mill of main milling cutter both sides also starts valve pocket to cut, due to the certain angle that is inclined upwardly from inside to outside of the cutting edge on side mill, will form at the opening part of valve pocket datum hole acclivitous inclined-plane like this, it is the chamfered part of datum hole, adopt as can be seen here this cutter can be disposable by the datum hole machine-shaping of valve pocket, can effectively enhance productivity, reduce labor intensity of operating staff, reduce enterprise's production cost.

The specific embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this description.
Refer to Fig. 1 to Fig. 4.Notice, appended graphic the illustrated structure of this description, ratio, size etc., equal contents in order to coordinate description to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of the utility model, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the object that can reach, all should still drop in the scope that technology contents that the utility model discloses will contain.Simultaneously, in this description, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when being also considered as the enforceable category of the utility model.
As shown in Figure 2, the utility model provides a kind of valve pocket baseline trough process tool, this cutter comprises a main milling cutter 2, in the both sides of main milling cutter 2, be respectively equipped with a side mill 3, two side mills 3 are symmetrical arranged along the longitudinal center line of main milling cutter 2, the circle diameter of side mill 3 is less than the circle diameter of main milling cutter 2, and the diameter of side mill 3 should be determined according to the size of chamfering on valve pocket 1.Side mill 3 should be close to main milling cutter 2, and side mill 3 is coaxially fixedly connected with main milling cutter 2.
Side mill 3, first passes successively two side mills 3 and main milling cutter 2 by a rotating shaft along orientation, and is fastenedly connected at the arranged outside clamp nut of two side mills 3 fixedly time with main milling cutter 2.In order to guarantee side mill 3, synchronize with main milling cutter 2, can on two end faces of main milling cutter 2, be provided with draw-in groove 22, the projection corresponding with draw-in groove 22 shapes is set simultaneously on the inner side end of side mill 3, and projection is connected in draw-in groove 22, so just can realize the synchronous rotary of side mill 3 and main milling cutter 2.
As shown in Figure 3, on the outer peripheral face of main milling cutter 2, be provided with several main cutting edges 21, on the outer peripheral face of side mill, be provided with several side cutting edges, the shape of its shape and main cutting edge 21 is basic identical, the difference of side cutting edge and main cutting edge 21 be side cutting edge from inside to outside (by main milling cutter to side mill direction) certain angle is inclined upwardly.According to the angular dimension of chamfering, side cutting edge from inside to outside acclivitous angle is generally 30 °, 45 ° or 60 °.
Because valve pocket 1 is thin-wall part, so main cutting edge 21, side cutting edge can select straight-tooth blade, and the width of main cutting edge, side cutting edge is less than 20mm.Can play better cutting effect like this, make the finished surface of baseline trough 11 more smooth.
As shown in Figure 4, this valve pocket baseline trough process tool is connected with drive motors 4 after three knife combinations are connected, at the baseline trough on valve pocket, add man-hour, first by 2 pairs of valve pockets 1 of main milling cutter, cut, when main milling cutter 2 is cut to after certain depth, the side mill 3 of main milling cutter 2 both sides also starts valve pocket 1 to cut, due to the certain angle that is inclined upwardly from inside to outside of the cutting edge on side mill 3, will form at the opening part of valve pocket datum hole 11 acclivitous inclined-plane like this, i.e. chamfering 12 parts of datum hole.
Adopt as can be seen here this cutter disposable the datum hole machine-shaping of valve pocket can effectively be enhanced productivity, reduce labor intensity of operating staff, reduce enterprise's production cost.So the utility model has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under such as and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
