Abstract
The utility model discloses a boring cutter adjusting device, and belongs to the field of metal processing cutters. An existing traditional adjusting device has the defects of operation complexity and low adjusting accuracy. The boring cutter adjusting device comprises a cutter bar, a cutter holder, an adjusting mechanism, a slider and a lead screw mechanism, the cutter holder is provided with a T-shaped guide track groove, the cutter bar is mounted on the slider, the lead screw mechanism is penetratingly mounted in the cutter holder, a lead screw and the slider are in through connection through matching of a nut, the nut is fixedly connected with the slider, and the adjusting mechanism is arranged inside the cutter holder, staggered with the lead screw mechanism, arranged on a shaft of the lead screw and meshed with the lead screw. Micro-adjustment of the adjusting mechanism to the lead screw is improved, and accuracy and working efficiency of a boring cutter are improved.
Description
Technical field
The utility model belongs to the metal working tool field, relates to the adjusting device that is used for knife bar in a kind of lathe.
Background technology
Traditional eccentric trimming boring bar, it comprises eccentric bushing, knife bar, inserts and alignment pin, inner cylinder face axis and the main-shaft axis of eccentric bushing have eccentric throw, the face of cylinder and the eccentric bushing of knife bar in eccentric bushing closely cooperates, eccentric bushing is provided with screw rod and hole, knife bar is provided with insert groove and location key seat, inserts that it is corresponding with screw rod to be located in insert groove, and alignment pin is corresponding with the hole on location key seat.When knife bar rotated in eccentric bushing, by the eccentric throw between its axis and main shaft, the distance that changes cutting point and main shaft realized fine setting.But the dial that can not show the amount trimmed size can not settle at one go, eccentric bushing processing trouble, and cost is higher.
The utility model content
The purpose of this utility model is exactly to have complicated operation, the low defective of degree of regulation in order to overcome existing conventional adjustment means, and a kind of simple in structure, easy and simple to handle, micromatic setting that amount trimmed is trickle is provided.
For this reason, the utility model is by the following technical solutions: a kind of boring cutter adjusting device, comprise knife bar, tool rest, slide block and screw body, tool rest arranges T shape guide-track groove, knife bar is loaded on slide block, it is characterized in that, described adjusting device also comprises governor motion, screw body is arranged in tool rest, is arranged in tool rest, coordinates switching by nut between screw mandrel and slide block, nut is fixedly connected with slide block, it is inner and staggered with screw body that governor motion is located at tool rest, and governor motion is located on the axle of screw mandrel, meshes with screw mandrel.
As to technique scheme replenish and perfect, the utility model also comprises following technical characterictic.
Described governor motion comprises worm-and-wheel gear and master calibration dish, and worm gear is arranged on the axle of screw mandrel, and is coaxial with screw mandrel, worm and wheel engagement, and the master calibration dish is arranged on the outer face of worm screw place axle.
Secondary dial is set on described screw mandrel, and secondary dial is arranged on the outside of described screw mandrel place axle.
Described knife bar fixedly mounts on slide block by pressing plate.
When the utility model uses, after slide block passes through the coarse adjustment of screw mandrel, rotary worm drives the gear that is engaged with, again by driving with the coaxial screw mandrel of worm gear the slide block that nut is fixedly connected with nut, the knife bar synchronizing moving, in adjustment process, make slide block do imperceptible movement by worm-and-wheel gear, realize the superfine fine setting of knife bar.
Use the utility model can reach following beneficial effect: the utility model has increased governor motion to be regulated the trace of screw mandrel, has improved the precision of boring cutter and the efficient of work.
