Description
Technical field
The invention belongs to machining tool field, be specifically related to a kind of waist-shaped hole broaching tool.
Background technology
At present, the processing mode of waist-shaped hole mainly has two kinds, and a kind of is add man-hour for the waist-shaped hole in thickness smaller parts, it is common to Milling Process after employing prebored hole; Another kind is to add man-hour for the waist-shaped hole on the bigger part of thickness, it is common to linear cutter after employing prebored hole. In both processing modes, the former machining accuracy is low, the latter's processing cost high. For high-volume, oversupplied goods, above two processing mode more seems that working (machining) efficiency is low, processing cost is high.
Summary of the invention
It is an object of the invention to the deficiency overcome existing for prior art, it is proposed to one adds man-hour suitable in waist-shaped hole on high-volume, oversupplied goods, not only machining accuracy is high, cost is low, and a kind of waist-shaped hole broaching tool that working (machining) efficiency is high.
The technical scheme realizing above-mentioned purpose is: a kind of waist-shaped hole broaching tool, it is the overall rod member that a section is similar to " waist type ", is followed successively by handle of a knife, front cutter and rear cutter from front to back. In the middle part of described handle of a knife, top and bottom are provided with two clamping grooves, described front cutter lower middle part is provided with one group and is parallel to each other and is the front cutting edge of �� with cutter hub vertical cross section angle, handle of a knife and front cutter are arranged above with escape groove, and on described rear cutter, Middle face is provided with one group and is parallel to each other and is the rear knife edge of-�� with cutter hub vertical cross section angle.
Further, cutter hub width h is equal to waist-shaped hole two ends arc radius R to be processed equal to waist-shaped hole length H to be processed, cutter hub both sides arc radius r; The maximum gauge b of cutter hub top and in the rear blade front and rear sections and cutter hub bottom and at the thickness b of described front cutting edge back segment equal to waist-shaped hole two ends arc radius R to be processed; Cutter hub bottom and at the maximum gauge a of described front cutting edge leading portion equal to waist-shaped hole to be processed three prebored holes intersection point m, n or o, p to the vertical dimension A of the prebored hole line of centres; The height c of described front cutting edge and described rear knife edge, is all incremented to b from a from first blade c1 to last blade cn successively.
Further, described escape groove degree of depth d is equal to the radius R of waist-shaped hole more than the radius R1-A of prebored hole, the radius R1 of prebored hole; Escape groove width e is not less than the distance between three prebored hole intersection point m and n.
The effect of the present invention is: during a kind of waist-shaped hole broaching tool batch machining waist-shaped hole manufactured according to such scheme, precision is high, efficiency high, cost is low, and can time processing molding.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Fig. 1��Fig. 5 and Fig. 7��10 figure, one waist-shaped hole broaching tool of the present invention is the overall rod member that a section is similar to " waist type ", is followed successively by handle of a knife 1, front cutter 2 and rear cutter 3 from front to back. In the middle part of described handle of a knife 1, top and bottom are provided with two clamping grooves 101, are connected with broaching machine when being used for broaching. Described front cutter 2 lower middle part be provided with one group be parallel to each other and with the front cutting edge 201 that cutter hub vertical cross section angle is ��, to cut the surplus to be processed below prebored hole. Handle of a knife 1 and front cutter 2 are arranged above with escape groove 1201, in order to before rear cutter 3 starts processing, handle of a knife 1 and front cutter 2 pass through from prebored hole. On described rear cutter 3 Middle face be provided with one group be parallel to each other and with the rear knife edge 301 that cutter hub vertical cross section angle is-��, to cut the surplus to be processed above prebored hole.
As shown in Fig. 1��Fig. 6 and Figure 11, cutter hub width h is equal to waist-shaped hole two ends arc radius R to be processed equal to waist-shaped hole length H to be processed, cutter hub both sides arc radius r; The maximum gauge b of cutter hub top and in the rear blade 301 front and rear sections and cutter hub bottom and at the thickness b of described front cutting edge 201 back segment equal to waist-shaped hole two ends arc radius R to be processed; Cutter hub bottom and at the maximum gauge a of described front cutting edge 201 leading portion equal to waist-shaped hole to be processed three prebored holes intersection point m, n or o, p to the vertical dimension A of the prebored hole line of centres; The height c of described front cutting edge 201 and described rear knife edge 301, is all incremented to b from a from first blade c1 to last blade cn, it is ensured that the cutting output of each blade is within tolerance band successively.
As shown in Fig. 3, Fig. 4 and Fig. 6, the degree of depth d of described escape groove 1201 is equal to the radius R of waist-shaped hole more than the radius R1-A of prebored hole, the radius R1 of prebored hole; The width e of escape groove 1201 is not less than the distance between three prebored hole intersection point m and n, in order to before rear cutter 3 starts processing, handle of a knife 1 and front cutter 2 pass through from prebored hole.
As shown in Fig. 6 and Figure 11, before wire pulling method waist-shaped hole, should holing in advance, three prebored hole diameter is identical, pitch-row is equal, be centrally located at same straight line, and the length H1 of prebored hole and the length H of radius R1 and waist-shaped hole to be processed and radius R is equal respectively. Length according to waist-shaped hole, prebored hole can be three, it is also possible to is two or more, and when prebored hole is two, in Fig. 6, intersection point n, o overlap respectively at m, p; When prebored hole is multiple, intersection point n, m and o, p respectively outermost two intersection points up and down in Fig. 6.
As shown in Fig. 6��Figure 10, add man-hour, first by handle of a knife 1 traverse prebored hole, again through clamping groove 101, broaching tool is connected with broaching machine, then starts broaching, until first blade c1 and prebored hole intersection point o of front cutting edge 201, p-contact (such as Fig. 6, Fig. 7), wire pulling method starts below, when broaching tool moves on until last blade cn of front cutting edge 201 is by after prebored hole, cutting below terminates, machine-shaping below waist-shaped hole (such as Fig. 8).(such as Fig. 6, Fig. 9) is contacted with prebored hole intersection point m, n when broaching tool is further continued for advancing to first blade c1 of rear knife edge 301, wire pulling method starts above, when broaching tool is further continued for advancing up to last blade cn of rear knife edge 301 by after prebored hole, cutting above terminates, the above machine-shaping (such as Figure 10) of waist-shaped hole, so far, waist-shaped hole process finishing.
