The specific embodiment:

In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.

Show the specific embodiment of a kind of slot making machine structure of the present invention like Fig. 1 to Fig. 4, comprise boring row 1, boring is arranged and is provided with first step hole 2 and second step hole 3 in 1 left end; The diameter in first step hole 2 is greater than the diameter in second step hole 3, and first step hole 2 places the left side in second step hole 3, and first step hole 2 communicates with second step hole 3; Boring is arranged 1 one distolateral walls and is connected with cover plate 5 through bolt 4, is provided with in the first step hole 2 on first push broach row, 6, the first push broach row 6 the right side wall of taper and is connected with second push broach row 7 who is complementary with second step hole 3; Be provided with the right side that groove 8 and second groove, 19, the second grooves 19 place groove 8 in first push broach row 6 the left side wall, the diameter of groove 8 is greater than the diameter of second groove 19; Groove 8 inside are connected with the adjusting rod 10 of horizontal placement through bearing 9, and an end of adjusting rod 10 is connected with round nut 12, and round nut 12 places second groove 19; Screw thread in the round nut 19 is divided into three sections, is equipped with screw thread in two sections about promptly, does not have screw thread in the interlude; Also be with back-up ring 11 on the adjusting rod 10, back-up ring 11 is positioned at the left end of bearing 9, and places first push broach row 6 inwall; The other end of adjusting rod 10 passes cover plate 5; Place the outside of cover plate 5, be with the holder group on the boring row 1, the holder group comprises first holder 13 and the 4th holder 14; Be provided with tool rest 15 between the top of first holder 13 and the 4th holder 14; Run through being provided with the spring lever 16 laterally placed in the bottom of tool rest 15, spring lever 16 is positioned at the bottom that all is connected with spring 17 on the position at tool rest 15 two ends, and the top of two springs 17 all is connected with the slotted screw 18 that is used for regulating spring power; Two slotted screws 18 place first holder 13 and the 4th holder 14 respectively, and the bottom of tool rest 15 is passed boring row 1 and contacted with first push broach row 6 taper seat.

Slot making machine structure of the present invention does not rotate with hand secured adjusted bar 10 in use, with loading onto cutter in the tool rest 15, the point of a knife tool setting; To after putting in place, produce relative motion between machine tool chief axis rotation adjusting bar 10 and the push broach row at point of a knife, push broach row is rotatable can not to rotate yet, and adjusting rod push-and-pull push broach row carries out side-to-side movement; Because first push broach row 6 is taper, thereby tool rest is moved up and down, in a moving week of boring row revolution, push broach row moves axially 1mm; Thereby let tool rest and point of a knife move radially 0.06mm, through the elastic force of slotted screw 18 regulating springs 17, when tool rest 15 moved up and down, spring can increase can reduce resistance; Thereby make tool rest 15 slowly move, and when using this mechanism, can be not stuck when adjusting rod 10 is arranged the push broach pole location with push broach, i.e. when 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, and concrete operation principle is following: boring row links to each other with main shaft through the taper shank (tapering can be decided according to the model of spindle hole) of rear end, and adjusting rod is not rotate but can axially move forward and backward; With the turret head of handle pinning adjusting rod front end, boring is arranged when only rotating and adjusting rod produces relative rotation during operation, and adjusting rod is because the screw thread on the boring row front shroud; Adjusting rod is moved forward and backward, the moving forward and backward of adjusting rod, thus promoted moving axially of push broach bar; True push broach bar is rotatable, also might not rotate, and needs only the push broach bar during use and produces axial displacement; Because the moving back of push broach bar pulled out and impelled cutter to sit to move radially, move radially the function that groove is colluded in realization from promoting cutter, this slot making machine structure is simple in structure; It is comparatively convenient to use, and has improved the precision of workpiece, has guaranteed workpiece quality.
