Abstract
The invention discloses an eccentric compensating tool apron, which comprises a tool apron and a reducing sleeve, wherein the tool apron is provided with a through hole; the reducing sleeve is sleeved and fixed in the tool apron through the through hole; the tool apron is fixed on a tool turret through a bolt; the reducing sleeve is provided with a through hole which is matched with a drill bit; the tool apron is an elastic tool apron; the reducing sleeve is an eccentric reducing sleeve; the eccentric reducing sleeve is sleeved in the elastic tool apron through a compression screw; the elastic tool apron is provided with ball grooves and locking bolts which are matched with each other; and the elastic tool apron is matched with the locking bolts through the ball grooves, so that slight deformation locking is realized. The tool apron is simple in structure, the tool turret of a machine tool is not required to be detached for repairing, production time is saved, the labor intensity of workers is lowered, the coaxiality error of the tool turret can be adjusted in a stepless way, the processing accuracy is increased, and the production efficiency is increased simultaneously.
Description
Technical field
The invention belongs to the Digit Control Machine Tool drilling aid, be 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 installed on the cutter tower, drill bit is installed in the conventional tool rest endoporus of packing into behind the 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 because a variety of causes precision meeting variation, particularly the axiality of conventional tool rest endoporus and main shaft can become large, when using bit bore, do not reach the installation accuracy of drill bit, 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.
Summary of the invention
The problems referred to above that exist in order to overcome the prior art field the object of the invention is to, and 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.
Eccentricity compensation tool rest provided by the invention, it comprises tool rest, drill holder, described tool rest is provided with through hole, drill holder is fixed in the tool rest by the through hole suit, tool rest is bolted on the cutter tower, described drill holder is provided with the through hole that cooperates 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 cooperates the little distortion locking of realization by playing groove with clamping screw.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.
Eccentricity compensation tool rest provided by the invention, its beneficial effect are that 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.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the embodiment of the invention.
Mark among the figure:
1. drill bit; 2. eccentric drill holder; 3. elasticity tool rest; 4. clamping screw; 5. bolt; 6. graduation mark; 7. bullet groove.
The specific embodiment
