Abstract
The utility model belongs to the mechanical manufacturing field and relates to a compound cutter for plastic and digital control hole thereof. The cutter comprises a drilling part, a broaching part, transiting parts, a reaming part, a chamfering part and a clamping part. The drilling part is arranged at one end of the cutter; the drilling part is connected with the broaching part; the broaching part is connected with one end of the reaming part through a front transiting part; the other end of the reaming part is connected with one end of the chamfering part through a rear transiting part; the other end of the chamfering part is connected with the clamping part. The cutter is integrated without four processes of drilling, broaching, reaming and chamfering to form a compound cutter, therefore, the processes of drilling, broaching, reaming, chamfering and the like can be finished once, especially suitable for nonmetallic materials with large heat sensitive and thermal expansion coefficient. The manufactured hole has no overburning, deposition, cracking, fogging, laminating, denting and the like, the dimensional accuracy of the manufactured hole can reach plus or minus 0.02mm and surface roughness 0.1mum.
Description
Technical field
The utility model belongs to mechanical manufacturing field, relates to a kind of a kind of plastics numerical control drilling compound tool that is used for plastics and product numerical control drilling thereof.
Background technology
Plastics have bigger heat sensitivity and thermal coefficient of expansion, and little two orders of magnitude of thermal conductivity ratio metal material, mechanical processing process, particularly in the boring procedure, cooling, lubricated, chip removal and heat radiation difficulty, hot buildup very easily appears in hole wall, and cause " burning ", deposited, be full of cracks, send out mist, layering and collapse phenomenon such as limit, be a procedure the most responsive in the machining.
Processing for high accurate hole, the general process combination that adopts boring, fraising, chamfering or boring, reaming, fraising, chamfering respectively, finish the processing of high accurate hole, its manufacturing procedure is many, complex process, and the error that last procedure stays is difficult in next procedure and eliminates, and causes the hole quality low.
Summary of the invention
It is few that the purpose of this utility model provides a kind of manufacturing procedure, the simple a kind of plastics numerical control drilling compound tool of technology.Technical solution of the present utility model is: cutter is made up of bore portion, reamer, transition part, fraising portion, chamfered section and clamping part, bore portion places an end of cutter, bore portion and reamer are joined, reamer is joined by an end of preceding transition part and fraising portion, the other end of fraising portion joins by an end of back transition part and chamfered section, and the other end and the clamping part of chamfered section join.The outer rim of fraising portion is provided with six sword straight-tooth, and chamfered section is one fan-shaped and evenly be provided with blade in outer rim.
Advantage that the utlity model has and beneficial effect, the utility model is integrated in boring, reaming, fraising and the required cutter of chamfering four procedures on the cutter, make the integral type compound tool, make operations such as boring, reaming, fraising and chamfering once finish, be specially adapted to the big nonmetallic materials of heat sensitivity and thermal coefficient of expansion, machining hole do not have " burning ", deposited, be full of cracks, send out mist, layering and collapse phenomenon such as limit, the dimensional accuracy in hole can reach ± 0.02mm, and surface roughness can reach 0.1 μ m.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Cutter is made up of bore portion 1, reamer 2, transition part 3, fraising portion 4, chamfered section 5 and clamping part 6, bore portion 1 places an end of cutter, bore portion 1 is joined with reamer 2, reamer 2 is joined by an end of preceding transition part 3-1 and fraising portion 4, the other end of fraising portion 4 joins by an end of back transition part 3-2 and chamfered section 5, and the other end of chamfered section 5 and clamping part 6 join.
The outer rim of fraising portion 4 is provided with six sword straight-tooth, and chamfered section 5 is one fan-shaped and evenly be provided with blade in outer rim.
The clamping part 6 of cutter is clamped on the lathe, bore portion 1 places the front end of cutter, after the boring, reamer 2 will directly be carried out reaming by the hole that bore portion 1 gets out, broken cutting through the preceding excessive 3-1 of portion under the cutting discharged, and cutter continues to move ahead, and carries out ream by 4 pairs of processed holes of fraising portion, cut with scissors out broken cut through after excessively the 3-2 of portion discharge, chamfered section 5 last to Hole chamfering until the processing of finishing the hole.
