Abstract
The invention discloses an involute spline push broach, which comprises a general cutter body, a general gasket, a positioning pin, a feather key, locking socket head cap screws, a left blade, a right blade, and a nut, wherein the involute spline push broach consists of five push broaches; the total length of each push broach is equal; the numbers of teeth of the blades of a first push broach, a second push broach, a third push broach and a fourth push broach are equal; the teeth of the blade of a fifth push broach are more than those of each of the blades of the first push broach, the second push broach, the third push broach and the fourth push broach; and the general cutter body is integrated with the left blade (8) and the right blade (9) through the nut (9), the general gasket (2), the positioning pin (3), the feather key (4), and the socket head cap screw (5) and (6). The involute spline push broach not only is clamped and positioned reliably, is convenient to assemble and disassemble, and saves cutter materials, but also can effectively improve the production efficiency and reduce the manufacturing cost. The involute spline push broach is suitable for machining an annular gear with large modulus, diameter and cutting length.
Description
Technical field
The present invention relates to a kind of involute spline push broach, belong to metal cutting tool class complex cutting tool technical field.
Background technology
The method of processing involute spline holes is more, and method commonly used is to adopt pinion cutter gear shaping and broaching tool to draw tooth.The operating efficiency of gear shaping is lower with respect to drawing tooth, draws the operating efficiency of tooth higher.For drawing tooth, prior art processing involute is along with splined hole modulus size and the different of length of broaching, involute profile can be pulled out with a broaching tool, also can pull out a cover broaching tool with two, three, when modulus during less than 3.5 millimeters, with one broaching tool be pulled out; Modulus equals 4 millimeters, broaching length and equals 80-120 millimeter or modulus and equal 5 millimeters, when broaching length equals the 50-80 millimeter, overlap broaching tools with two one and pull out; Modulus equals 5 millimeters, when broaching length equals 80-120 millimeter or modulus greater than 6 millimeters, overlaps broaching tool to one with three and pull out.As mentioned above, equal 5 millimeters with modulus, the maximum diamater of work equals 70 millimeters of 67 millimeters, length of cut and is example, and according to design, the total length of broaching tool is 1345 millimeters.If, modulus greater than 6 millimeters, the maximum diamater of work greater than 200 millimeters, broaching length during greater than 120 millimeters, just very uneconomical with said method design broaching tool: the one, broaching tool is oversize, broaching machine is difficult to meet the demands; The 2nd, just present, the source of cutter material is very difficult again.Therefore, it is very difficult providing such cutter.The enterprise that produces ring gear very urgently wishes to come processing involute spline holes with working (machining) efficiency technique higher, that manufacturing cost is lower.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of involute spline push broach, and it not only clamps, locate reliable, and mounting or dismounting are convenient, saves cutter material, and very effectively enhances productivity and reduce manufacturing cost.Use the present invention's workpiece same with using pinion cutter processing to compare, operating efficiency can improve more than hundred times.
For solving the problems of the technologies described above, the invention provides a kind of involute spline push broach, it comprises general cutter hub, general packing ring, alignment pin, feather key, soket head cap screw, left blade, right blade, nut.The present invention has five push broach and forms, and every total length push broach is identical, and the first to the four equates that the 5th the tooth on the push broach blade, more the number of teeth of push broach than front four to the number of teeth on the blade of push broach; General cutter hub is connected as a single entity by nut, general packing ring, alignment pin, feather key, locking soket head cap screw and left blade and right blade.
Left blade and right blade are rounds, and the tooth that its outer surface is provided with is involute profile, and tooth top section has chip-breaker; Its inner surface cooperates with the outer surface of general cutter hub left end cylinder; Its raw material are forge piece, and machining and heat treatment are carried out in grouping, so that the quality of control push broach.
Alignment pin and feather key are integrated positioning spare, and they are separately positioned in the locating hole and guide key groove between left blade and the right blade binding face.
Nut is threaded with general cutter hub left end, and four locking soket head cap screws are housed on its left side.
Because above-mentioned involute spline push broach adopts five push broach, so it is long to have overcome the prior art broaching tool, the difficult choosing of cutter material, the low deficiency that waits of working (machining) efficiency.Simultaneously, owing to adopt five push broach, each push broach is divided into blade again left and right blade manufacturing, not only can fully guarantee the quality of push broach, and, can save equipment investment.
Description of drawings
Fig. 1 is a kind of involute spline push broach structural representation provided by the invention.
Among Fig. 1: 1. general cutter hub, 2. general packing ring, 3. alignment pin, 4. feather key, 5. soket head cap screw, 6. locking soket head cap screw, 7. right blade, 8. left blade, 9. nut.
The specific embodiment
Among Fig. 1, a kind of involute spline push broach, it comprises general cutter hub 1, general packing ring 2, alignment pin 3, feather key 4, soket head cap screw 5, locking soket head cap screw 6, right blade 7, left blade 8, nut 9.This involute spline push broach has five push broach and forms, and every total length push broach is the same, and the first to the four equates that the 5th the tooth on the push broach blade, more the number of teeth of push broach than front four to the number of teeth on the blade of push broach; General cutter hub 1 by nut 9, general packing ring 2, alignment pin 3, feather key 4, soket head cap screw 5 and 6 and left blade 8 and right blade 7 be connected as a single entity.Left blade 8 and right blade 7 are at hollow cylinder, and the tooth that its outer surface is provided with is involute profile, and tooth top section has chip-breaker; Its inner surface cooperates with general cutter hub 1 left end cylindrical outer surface; Its raw material are forge piece, and machining and heat treatment are carried out in grouping, so that the quality of control push broach.Alignment pin 3 and feather key 4 are integrated positioning spare, and they are accurately located left blade 8 and right blade 7.Nut 9 is connected with general cutter hub 1, and in nut 9 left sides soket head cap screw is housed, so that nut and general cutter hub can not become flexible after clamping.
Because this involute spline push broach adopts five push broach, so it is long to have overcome the prior art broaching tool, the difficult choosing of cutter material, the low deficiency that waits of working (machining) efficiency.Simultaneously, owing to adopt five push broach, each push broach is divided into blade again left and right blade manufacturing, can fully guarantee the quality of push broach, can also save equipment investment.
The present invention clamps, locates reliable, and mounting or dismounting are convenient, saves cutter material, can Effective Raise production efficiency and the manufacturing cost that reduces work piece.
