Abstract
The utility model relates to the technical field of a numerical-control countersinking high-efficiency machining cutter. During the machining process of the parts such as discs, rings and the like in the prior art, bore machining is needed in certain cavities; especially during the reverse filleting or reverse milling machining process of the hole, as the dimension of the rod part of the cutter is larger than the diameter dimension of the hole, the cutter can not reach the bottom of the hole directly, thus leading the machining process to be inconvenient. The utility model aims at providing the numerical-control countersinking high-efficiency machining cutter. The structure of the cutter is formed by fixedly clamping the dismountable cutting head parts at the end part of the cutting rod part; and a countersinking machining blade is fixed on the cutting head. The numerical-control countersinking high-efficiency machining cutter has the purposes and effects of ensuring that the countersinking machining (which can not be completed by a normal cutter) of the hole of the part can be completed within twice clamping. The machining efficiency is improved, and the problem that the countersinking machining of the hole of the existing parts during the machining process can not be normally carried out is solved, therefore, the numerical-control countersinking high-efficiency machining cutter is suitable for the porous parts which have small counterbore and large countersinking hole and are difficult to machine in reverse direction.
Description
Technical field
The utility model belongs to numerical control machining cutter technical field in the machining, relates to the anti-ream highly-efficient processing of a kind of novel numerical control cutter.
Prior art
At present, in dish, ring parts process, because design of part is big and more complicated, a lot of structural members and weldment have been comprised, hole processing need be carried out in some die cavity inside in these structural members, yet, add man-hour with general universal cutter, because design of part is comparatively complicated, so often there be the instead circle or counter the milling in the process of interference, particularly hole in cutter when these porose positions of processing, because tool bar portion size is greater than the diameter dimension in hole, cutter can not directly arrive at the bottom of the hole, so bring a lot of inconvenience to processing down.
Online in State Intellectual Property Office, announced the patent of a kind of " the anti-countersink tool that is used for digital control processing " on March 31st, 2004, patent (application) number CN03134487.9, its content is the anti-countersink tool that is used for digital control processing, carry out anti-ream processing with Digit Control Machine Tool, improve anti-ream crudy, the hole hollow of cutter hub is with cam, be installed with push rod in cam, between cam and push rod spring be housed, the positioning clamping pin that is connected on the cutter hub is inserted in recessed poor in the cam, on cam, be fixed with knife bar, push rod is through in the hole of knife bar, and the knife bar cylindrical is equipped with knife bar top cover by screw thread, and nut is used for locking top cover, bearing pin is housed on the knife bar, cutter head is contained on the bearing pin, can rotate around bearing pin, and groove is arranged on the cutter head, the round pin of push rod termination enters in the groove on cutter head two sides, make cutter head be rotated counterclockwise 90 ° when push rod retreats, the width of being slotted in the push rod termination equals the cutter head width, and cutter head is inserted in this groove.
Summary of the invention
The purpose of this utility model provides a kind of anti-ream highly-efficient processing of numerical control cutter of new structure.This structure is divided into two parts, and knife bar part and cutter head part are cut processing problems for the traditional method of indicating the pronunciation of a Chinese character that solves above-mentioned prior art mesopore, allows knife bar partly following at the bottom of the hole earlier, and then cutter head partly is contained on the knife bar, so just can carry out the traditional method of indicating the pronunciation of a Chinese character in hole and cut processing.
The technical scheme that the utility model adopted is (in order better to understand technology contents, the parts label is placed in the bracket among the figure): the anti-ream highly-efficient processing of numerical control cutter, by cutting bar portion (3) end clamping fixedly cutting head (1) form, be characterized in: cutting bar portion (3) end clamping is fixed dismountable cutting head (1), and cutting head (1) is fixed with anti-ream machine and adds blade (2).
The technical scheme that the utility model adopted also comprises: the anti-ream highly-efficient processing of described numerical control cutter is characterized in that: the clamping securing member at the fixing dismountable cutting head (1) of cutting bar portion (3) end clamping is screw, bolt or interior six square bolts.
The beneficial effects of the utility model are: can guarantee that part finishes the anti-ream processing in the hole that normal cutter can't machine on the part in being no more than 2 times clamping.Avoided multiple clamping or repeatedly tool changing, improved working (machining) efficiency, the anti-ream that has solved existing part work in-process hole is processed the problem that can't normally carry out.The utility model is applicable to that counterbore is little, and anti-spot-facing is big, simultaneously reverse unmanageable class part with holes.
Description of drawings
Fig. 1 is the utility model process tool head cutting structure schematic diagram.
Fig. 2 is that the process tool machine adds the bar structural representation.
Fig. 3 is the overall structure view.
Above-mentioned number in the figure explanation: 1, cutting head, 2, machine adds blade, 3, cutting bar portion.
The specific embodiment
Referring to each figure, overall structure by cutting bar portion 3 end clampings fixedly cutting head 1 form, be characterized in: cutting bar portion 3 end clampings are fixed dismountable cutting head 1, and cutting head 1 is fixed with anti-ream machine and adds blade 2.In the process by allowing the cutting bar portion 3 of Fig. 2 earlier earlier down at the bottom of want the hole of processing parts, and then the cutting head 1 cutting tip clamping of Fig. 1 fixed, fixing available left-hand thread is fixed in the cutting bar portion 3, form overall structure shown in Figure 3, utilize the machine of clamping on the cutting head 1 to add 2 pairs of processing parts of blade and carry out anti-spot-facing processing.
Claims (2)
1. the anti-ream highly-efficient processing of numerical control cutter, by cutting bar portion (3) end clamping fixedly cutting head (1) form, be characterized in: cutting bar portion (3) end clamping is fixed dismountable cutting head (1), and cutting head (1) is fixed with anti-ream machine and adds blade (2).
2. the anti-ream highly-efficient processing of numerical control according to claim 1 cutter is characterized in that: the clamping securing member at the fixing dismountable cutting head (1) of cutting bar portion (3) end clamping is screw, bolt or interior six square bolts.
