Abstract
The utility model discloses an eccentric compensation cutter holder which comprises a cutter holder body with a through hole, and a reducing sleeve sleeved in and fixed on the cutter holder body through the through hole, wherein the cutter holder body is fixed on a turret through bolts; the reducing sleeve is provided with a through hole matched with a drill bit; the cutter holder body is the elastic cutter holder body, and the reducing sleeve is the eccentric reducing sleeve which is sleeved in the elastic cutter holder body through compression screws; an elastic groove and locking bolts which are matched are arranged on the elastic cutter holder body; and micro-deformation locking of the elastic cutter holder body is realized through the coordination of the elastic groove and the locking bolts. The cutter holder has a simple structure, can perform repair without dismounting the machine tool turret, saves the production time, reduces worker labor intensity, realizes stepless adjustment of turret coaxiality error, and improves the machining precision and the production efficiency.
Description
Technical field
The utility model belongs to the Digit Control Machine Tool drilling aid, is specifically related to a kind of eccentricity compensation tool rest.
Background technology
The installation method of present conventional two-axis numerical control lathe drill bit is roughly the same, conventional tool rest is arranged on the cutter tower, drill bit is arranged on the conventional tool rest endoporus of packing into after conventional drill holder, when dispatching from the factory, conventional tool rest the axiality of its endoporus and main shaft has been adjusted, tolerance is generally in 0.02, drill holder cylindrical and endoporus also must have good axiality, so the axiality after the drill bit installation is good.
General lathe is in use for some time due to a variety of causes precision meeting variation, particularly the axiality of conventional tool rest endoporus and main shaft can become large, do not reach the installation accuracy of drill bit when using bit bore, cause the too short or product size variation of bit life, can't carry out the most at last product processing.
This conventional tool rest can't must be readjusted the circumferential precision of cutter tower by soft compensation adjustment in case produce coaxial error on the two-axis numerical control lathe, can't adjust when different cutter spacing different accuracy occurring.
The utility model content
The problems referred to above that exist in order to overcome the prior art field, the purpose of this utility model is, a kind of eccentricity compensation tool rest is provided, and when solving present machine tool tower and coaxial error occurring, can't by adjusting conventional tool rest recovery, affect the problem of product quality.
The eccentricity compensation tool rest that the utility model provides, it comprises tool rest, drill holder, described tool rest is provided with through hole, drill holder is set with by through hole and is fixed in tool rest, tool rest is bolted on the cutter tower, described drill holder is provided with the through hole that coordinates with drill bit, described tool rest is the elasticity tool rest, drill holder is eccentric drill holder, eccentric drill holder is sleeved in the elasticity tool rest by housing screw, described elasticity tool rest is provided with bullet groove, the clamping screw that cooperatively interacts, and the elasticity tool rest coordinates with clamping screw by the bullet groove realizes little distortion locking.It also comprises graduation mark, and described graduation mark is arranged on the sidewall of elasticity tool rest, on the end cylindrical of eccentric drill holder, and the elasticity tool rest is aimed at fixing with eccentric drill holder by graduation mark mutually.
The eccentricity compensation tool rest that the utility model provides, its beneficial effect be, this tool-apron structure is simple, need not to dismantle the machine tool tower and repair, saved the production time, reduced workman's labour intensity, can stepless adjustment cutter tower coaxiality error, improved machining accuracy, improved simultaneously production efficiency.
