Abstract
The utility model discloses a cutter for machining an external thread. The cutter comprises a cutter bar and a circular dental plate, two radial location holes are arranged on two sides of the outer circumference surface of the circular dental plate, a cylindrical stepped hole with a large front portion and a small rear portion is disposed at the front end of the cutter bar, two screwed holes which are communicated with a large cylindrical hole are machined on the outer surface of the cutter bar on two sides along the radial direction of the large cylindrical hole, the circular dental plate is installed on the large cylindrical hole of the cutter bar, screw plugs are installed on the two screwed holes which are communicated with the large cylindrical hole, the screw plugs and the radial location holes of the circular dental plate are matched and fasten the circular dental plate, a plurality of through holes which are communicated with a small cylindrical hole can be processed on the outer surface of the front end of the cutter bar, and the through holes are convenient to fill a cooling liquid. According to the cutter for machining the external thread, the production efficiency of machining the external thread by a machine tool of a numerical control machining center can be effectively improved, and qualities of workpiece external thread and qualified rate of batch products can be improved.
Description
Technical field
The utility model relates to machine tool, and especially a kind of suitable numerical control machining center lathe is used for the externally threaded cutter of processing work.
Background technology
Have now and on the numerical control machining center lathe, carry out the workpiece external screw thread and add man-hour; Usually the mode that adopts the standard thread milling cutter to utilize the NC programming to walk corresponding track along institute's externally threaded outline of processing work is come machine-shaping; But in practical operation; Can there be following problem in this processing mode: the vibration that 1, adds the workpiece in man-hour is bigger, and the thread surface that processes has tangible vibration tool marks, influences the crudy of thread surface; 2, add and often will adjust the cutter compensation amount man-hour and compensate the workpiece accuracy of screw machining, working (machining) efficiency is low, also can influence the qualification rate of product in batch.
The utility model content
The technical problem that the utility model will solve provides a kind of cutter of threading, can effectively improve the externally threaded production efficiency of numerical control machining center machine tooling, improves the externally threaded quality of workpiece and the qualification rate of product in batch.
For achieving the above object; The technical scheme of the utility model is: a kind of cutter of threading; Comprise knife bar, circular dental lamina; The both sides of circular dental lamina outer peripheral face are provided with two radial location holes, and the front end of knife bar is provided with a pre-large post-small cylindrical shoulder hole, on the knife bar outer surface of both sides, process two screwed holes that are communicated with the big column hole along the big column aperture; Circular dental lamina is installed on the big column hole of knife bar, and the radial location hole that plug screw and circular dental lamina are housed on the screwed hole in two connection big column holes matches to merge and tightens up circular dental lamina.
Further improve, also be processed with the through hole of a plurality of connection small cylindrical openings on the outer surface of said knife bar front end, convenient input cooling fluid.
The shape of preferred said knife bar outer surface is roughly little cylindrical in the big rear end of front end, convenient processing.
The utility model utilizes knife bar to be contained in the cutter retained part of numerical control machining center lathe, and circular then dental lamina is enclosed within on the workpiece, comes the external screw thread of processing work through circular dental lamina and workpiece relative motion; Be equivalent to adopt screw tap to attack the same process of internal thread hole, Workpiece vibration is little, and process velocity is fast; The externally threaded quality of workpiece is obtained to guarantee by the thread form of circular dental lamina; In producing by batch, workpiece external screw thread processing differences is little, and yield rate is high.
Therefore the utility model can effectively improve the externally threaded production efficiency of numerical control machining center machine tooling, improves the externally threaded quality of workpiece and the qualification rate of product in batch; The utility model also can be applicable on the machining tool of non-numerical control function simultaneously.

The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is done further explain.
Fig. 1 is to shown in Figure 4, and a kind of cutter of threading comprises knife bar 1, circular dental lamina 2, and the shape of knife bar 1 outer surface is roughly little cylindrical in the big rear end of front end, and the both sides of circular dental lamina 2 outer peripheral faces are provided with two radial location holes 21;
The front end of knife bar 1 is provided with a shoulder hole that is combined by preceding big column hole 11 and back small cylindrical opening 12; Two screwed holes 13 that are communicated with big column holes 11 of processing on knife bar 1 outer surface of both sides radially along big column hole 11; Circular dental lamina 2 is installed on the big column hole 11 of knife bar 1, and the radial location hole 21 that plug screw 3 and circular dental lamina 2 are housed on the screwed hole 13 in two connection big column holes 11 matches to merge and tightens up circular dental lamina 2.
On the outer surface of knife bar 1 front end, also can be processed with the through hole 14 of a plurality of connection small cylindrical openings 12, be used to import cooling fluid.
When the utility model used, the cutter retained part that utilizes knife bar 1 rear end part to be installed in the numerical control machining center lathe can use.
The utility model knife bar 1 also capable of using is contained on the machining tool of non-numerical control function and processes.
Below only be preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
