The specific embodiment:
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the present invention, does not consist of the restriction to protection domain of the present invention.
Show the specific embodiment of a kind of grooving mechanism of the present invention such as Fig. 1 to Fig. 4, comprise boring row 1, be provided with first step hole 2 and second step hole 3 in boring row 1 left end, the diameter in first step hole 2 is greater than the diameter in second step hole 3, first step hole 2 places the left side in second step hole 3, first step hole 2 and second step hole 3 communicate, boring row 1 one distolateral walls are connected with cover plate 5 by bolt 4, be provided with the first push broach row 6 of taper in the first step hole 2, be connected with the second push broach row 7 who is complementary with second step hole 3 on the first push broach row 6 the right side wall, be provided with groove 8 and the second groove 19 in the first push broach row 6 the left side wall, the second groove 19 places the right side of groove 8, the diameter of groove 8 is greater than the diameter of the second groove 19, groove 8 inside are connected with the adjusting rod 10 of horizontal placement by bearing 9, one end of adjusting rod 10 is connected with round nut 12, round nut 12 places the second groove 19, screw thread in the round nut 19 is divided into three sections, be equipped with screw thread in two sections namely, in the interlude without screw thread, also overlap on the adjusting rod 10 back-up ring 11 is arranged, back-up ring 11 is positioned at the left end of bearing 9, and place the first push broach to arrange 6 inwall, the other end of adjusting rod 10 passes cover plate 5, place the outside of cover plate 5, cover has the holder group on the boring row 1, the holder group comprises the first holder 13 and the 4th holder 14, be provided with tool rest 15 between the top of the first holder 13 and the 4th holder 14, run through in the bottom of tool rest 15 and be provided with a spring lever 16 of laterally placing, spring lever 16 is positioned at the bottom that all is connected with spring 17 on the position at tool rest 15 two ends, the top of two springs 17 all is connected with the slotted screw 18 for regulating spring power, two slotted screws 18 place respectively the first holder 13 and the 4th holder 14, and the bottom of tool rest 15 is passed boring row 1 and contacted with the first push broach row 6 taper seat.
Grooving mechanism of the present invention in use, do not rotate with hand secured adjusted bar 10, to load onto cutter in the tool rest 15, the point of a knife tool setting, at point of a knife to after putting in place, produce relative motion between machine tool chief axis rotation adjusting rod 10 and the push broach row, push broach row rotatably can not rotate yet, adjusting rod push-and-pull push broach row carries out side-to-side movement, because the first push broach row 6 is taper, thereby tool rest is moved up and down, every one week of rotation of boring row, push broach row moves axially 1mm, thereby allow tool rest and point of a knife move radially 0.06mm, elastic force by slotted screw 18 regulating springs 17, when tool rest 15 moves up and down, spring can increase can reduce resistance, thereby so that tool rest 15 slowly moves, and when using this mechanism, can be not stuck when adjusting rod 10 is arranged the push broach pole location with push broach, when i.e. the second push broach row 7 reaches home the position in second step hole 3, adjusting rod 10 can unclamp round nut 12 not to be promoted, the specific works principle is as follows: boring row links to each other with main shaft by the taper shank (tapering can be decided according to the model of spindle hole) of rear end, adjusting rod is not rotate but can axially move forward and backward, pin the turret head of adjusting rod front end during operation with handle, produce relative rotation with adjusting rod when boring row only rotates, adjusting rod is because of the screw thread on the boring row front shroud, adjusting rod is moved forward and backward, moving forward and backward of adjusting rod, thus moving axially of push broach bar promoted, and true push broach bar is rotatable, might not rotate yet, during use as long as the push broach bar produces axial displacement, because the moving back to pull out and impel cutter to sit to move radially, move radially the function that groove is colluded in realization from promoting cutter of push broach bar, this grooving mechanism is simple in structure, it is comparatively convenient to use, and has improved the precision of workpiece, has guaranteed workpiece quality.
