Abstract

The utility model relates to a deep-hole processing cutting tool, in particular to a self-positioning cutting tool with a cooling fluid hole. The cutting tool mainly resolves the problems that 1 the strength of existing cutting tools are not enough in processing deep holes, accordingly the accuracy of holes is low; 2 single-blade cutting tools are low in processing capacity and processing efficiency; 3 service lives of existing cutting tools are easy to be shortened when heated, accordingly problems of being high in production cost and long in production cycle are caused. The deep-hole processing cutting tool comprises a cutter arbor and a cutting tool, and is characterized in that the cooling fluid hole is arranged along the cutter arbor, the cutting tool is fixed in a radial hole of the cutter arbor, two ends of the cutting tool are respectively fixed with blades, and one end of the cutter arbor close to the cutting tool is fixed with a guide bearing. In processing deep holes, the end portion of the cutter arbor is fixed with a bearing used for positioning and guiding, thus the deep-hole processing cutting tool guarantees that the roughness and sizes of the processed holes can meet the requirements. In process, the cooling fluid cools the cutting tool, thereby prolonging the service life of the cutting tool and reducing the processing cost.

Description

A kind of deep hole processing cutter

Technical field

The utility model relates to a kind of cutter, relates to a kind of cutter of self-align and band cooling fluid hole specifically.

Background technology

At present, the cutter of known cutter, especially deep hole processing, because knife bar is very long when deep hole processing, bad mechanical strength is trembled easily adding the man-hour knife bar, influence the roughness and the interior hole dimension in hole.Traditional cutter has only a blade, just has only a cutter in processing, and cutting output is little, long processing time.And the blade cut heat distributes difficulty when deep hole processing, and the cutter easy deformation influences cutter life, has increased processing cost.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned deficiency, and a kind of self locating device that has that provides, and has the deep hole processing cutter in cooling fluid hole.

Technical solution of the present utility model is: deep hole processing cutter comprises knife bar and cutter, it is characterized in that: be axially arranged with the cooling fluid hole along knife bar, cutter is fixed in the radial hole on the knife bar, and the two ends of cutter are fixed with blade respectively, is fixed with guide bearing at knife bar by an end of cutter.

The end in the cooling fluid hole described in the technical solution of the present utility model has the screw thread that is used for connecting external refrigeration liquid pipeline.

Guide bearing described in the technical solution of the present utility model is contained on the shaft shoulder of knife bar end, is fixed on the knife bar by pressing plate and clamping screw.

The utility model is owing to be fixed with the bearing that positioning and guiding is used in the end of knife bar, therefore when deep hole processing, vibration can not appear in knife bar, has guaranteed the precision and the dimensional requirement of being processed, be provided with the cooling fluid hole in the inside of knife bar, guaranteed that cutter can be cooled off fully when cutting, prolonged the service life of cutter, reduced cost of processing, a blade respectively is equipped with at the knife rest two ends of cutter, improve the cutting output that adds man-hour, shortened process time, improved production efficiency.

The specific embodiment

As shown in Figure 1, 2, the utility model mainly includes knife bar 1, cutter 4, guide bearing 6, along knife bar 1 be axially arranged with cooling fluid hole 2, this cooling fluid hole 2 is provided with screw thread by the place, end of knife bar 1, is used for being connected with coolant pipe; Have the shaft shoulder on the other end of knife bar 1, guide bearing 6 is installed on this shaft shoulder, and by pressing plate 7 and clamping screw 8 guide bearing 6 is fixed on the knife bar 1; Radially have a square through hole along knife bar 1, the knife rest of cutter 4 is packed in this square through hole, on guide rod 1, be provided with the screw that communicates with square through hole, available clamping screw 3 is locked at the knife rest of cutter 4 in the square opening on the knife bar 1, the two ends of cutter 4 knife rests be fixed with respectively blade 5, two blades 5 be symmetrically 180 the degree be fixed on the knife rest of cutter 4; When deep hole processing, knife bar 1 is clipped on the knife rest of lathe and locks, cutter 4 inserts in the square hole of knife bar 1, adjust the position of two blades 5 and use clamping screw 3 lockings, make the cutting output of two blades 5 suitable, one blade 5 is used for roughing, another blade 5 is used for fine finishining, can guarantee machining accuracy like this, process time can be shortened again, enhance productivity, guide bearing 6 is enclosed within on the shaft shoulder of knife bar 1 end, and compress with pressing plate 7 and clamping screw 8, play the positioning and guiding effect, in order to avoid processing knife bar vibration during deep and long hole, coolant pipe is received 2 li in the cooling fluid hole of knife bar 1 end, guarantee that cutter 4 can be cooled off fully when cutting, prolong the service life of cutter 4, reduce production costs.
