The external screw thread of described adjusting screw(rod) head and the external screw thread of root are reverse thread, and the externally threaded pitch of root is greater than the externally threaded pitch of head.
The external screw thread of the root of described adjusting screw(rod) is M30 × 1.5 right-handed thread, and the external screw thread of the head of described adjusting screw(rod) is M14 × 1.25 left hand thread.
The evenly divided that is provided with 50 lattice for one week of the handle of described adjusting screw(rod).
The good effect that the technical solution of the utility model produces is as follows: the surface of adjusting screw(rod) of the present utility model is provided with two groups of differential threads that pitch is different, realize the feeding of cutter holder by rotation adjusting screw(rod), degree of regulation is high, can realize meticulous feed, the externally threaded pitch of adjusting screw(rod) root is greater than the externally threaded pitch of its head, thereby the displacement that cutter holder axle is moved forward with respect to fixed mount is greater than the displacement that cutter holder axle moves backward with respect to adjusting screw(rod), therefore the moving distance of whole cutter holder axial advancement is very little, has improved the precision of cutter holder feeding.
Adjusting screw(rod) root external screw thread is M30 × 1.5 right-handed thread, and when Gu Dangqi clockwise rotates one week, the displacement that cutter holder axle moves forward with respect to fixed mount is 1.5mm; The screw thread being meanwhile connected with cutter holder axle due to adjusting screw(rod) head is M14 × 1.25 left hand thread, clockwise rotate one week simultaneously at adjusting screw(rod), this left hand thread is 1.25mm by the displacement that cutter holder axle is moved backward with respect to fixed mount again, so cutter holder axle is actual, to move forward displacement be 0.25mm, on the handle of adjusting screw(rod), there are evenly divided 50 lattice, so every fine setting one lattice cutter holder axle moving displacement 0.005mm of rotation adjusting screw(rod), can realize like this Precision trimming, the precision that effectively improves processing progress and cutter holder feeding, improves working (machining) efficiency.
Brief description of the drawings
Fig. 1 is that the master of the utility model differential thread trimming tool bit device is depending on dissecing structural representation.
Detailed description of the invention
A kind of differential thread trimming tool bit device, as shown in Figure 1, comprise cutter holder 1, cutter holder axle 3 and adjusting screw(rod) 6, the end of described adjusting screw(rod) 6 is provided with handle 9, described cutter holder 1 is connected with described cutter holder axle 3, described cutter holder axle 3 is movably arranged on fixed mount 4 inside, and described cutter holder axle 3 can move forward and backward in fixed mount 4, and described fixed mount 4 is by the fastening described cutter holder axle 3 of an anti-rotation trip bolt 2; On described cutter holder axle, offer an elongated slot, a feather key 7 is set in described elongated slot, described cutter holder axle 3 leads by feather key 7 in the time of inner movement of described fixed mount 4, and described feather key 7 is fastening by holding screw 8; The afterbody of described fixed mount 4 is provided with backing plate 5, described fixed mount 4 and described backing plate 5 closely cooperate, the center of described backing plate 5 offers internal thread hole, described adjusting screw(rod) 6 is arranged on cutter holder axle 3 inside through the internal thread hole of described backing plate 5, described cutter holder axle 3 inside are also provided with internal thread hole, head and the root of described adjusting screw(rod) 6 are provided with external screw thread, the external screw thread of described adjusting screw(rod) 6 heads matches with the internal thread hole of described cutter holder axle 3, and the external screw thread of described adjusting screw(rod) 6 roots matches with the internal thread hole of described backing plate 5.
The external screw thread of described adjusting screw(rod) 6 heads and the external screw thread of root are reverse thread, and the externally threaded pitch of root is greater than the externally threaded pitch of head.
The external screw thread of the root of described adjusting screw(rod) 6 is M30 × 1.5 right-handed thread, and the external screw thread of the head of described adjusting screw(rod) 6 is M14 × 1.25 left hand thread.
