Abstract
The utility model discloses a self-adaptation guide device for a numerical control horizontal type milling and boring machine, in particular provides a self-adaptation guide device for a leaner moving part, and belongs to the technical field of machine tool parts. The self-adaptation guide device is installed at the rear end portion of a ram seat to be connected with the moving part of the numerical horizontal type milling and boring machine, a butterfly-shaped spring is arranged in an adjusting seat and presses a bearing seat to enable the bearing seat to be integrally connected with a cylindrical roller bearing, a shaft sleeve is connected in the bearing seat, the cylindrical roller bearing passes by a partition ring to be connected with a shaft, and the cylindrical roller bearing is contacted with an auxiliary guide rail plate and can roll on the auxiliary guide rail plate. Due to the fact that the elastic butterfly-shaped spring has preloaded expansion force, the guide device can be automatically adapted to the influence of super poor parallelism and straightness of the guide rail, guide performance is ensured in real time, and machine tool machining precision is prevented from being influenced by inclination of a spindle box.
Description
Technical field
The utility model discloses a kind of cnc boring and milling machine and uses adaptive directed device, in particular for displacement part of straight line a kind of adaptive directed device is provided, and belongs to the machine tool accessory technical field.
Background technology
Cnc boring and milling machine for the band ram adds man-hour when ram moves forward and backward, perhaps skew before and after the center of gravity when the ancillary attachment of the equipped Different Weight of ram front end, and main spindle box generation fore-and-aft direction tilts and causes the machine tool accuracy forfeiture.To this problem, have to adopt at present expensive twoly drive two detection modes and control the ram seat and move up and down and to solve " inclination " precision problem.
Summary of the invention
The utility model purpose is that invention provides a kind of adaptive directed device for displacement part of straight line; This device is installed on the lathe moving-member; Its adaptive directed confining force size can be according to actual needs in given range rapid adjustment easily; Solve " inclination " precision problem, this reduces the lathe manufacturing cost widely.
The utility model CNC horizontal milling & boring machine with adaptive directed device mainly by holding screw (4), hexagon socket cap head screw (5), flat key (6); Straight pin (7), secondary guide rail plate (8), bearing block (9); Axle (10), spacer ring (11), cylinder roller bearing (12); Butterfly spring (13) and adjustment seat (14) constitute, and adaptive directed device is installed in ram seat (2) rearward end of CNC horizontal milling & boring machine and moves up and down along machine pillar (1) with ram seat (2);
Be placed with one group of butterfly spring (13) in the adjustment seat (14); Butterfly spring (13) is being pressed bearing block (9); Axle (10) connects as one bearing block (9) and cylinder roller bearing (12); Cylinder roller bearing (12) is through spacer ring (11) axial location, and after axle (10) radial location, cylinder roller bearing (12) is with secondary guide rail plate (8) real-time contact and can go up rolling at secondary guide rail plate (8);
Wherein adjustment seat (14) links together through holding screw (4), hexagon socket cap head screw (5), straight pin (7) with ram seat (2).Bearing block (14) links into an integrated entity with cylinder roller bearing (12) under the effect of butterfly spring (13) pretension expansive force; Along with the CNC horizontal milling & boring machine moving-member is gone up rolling at secondary guide rail plate (8); Butterfly spring (13) pretension expansive force forces the moving guide pass of CNC horizontal milling & boring machine moving-member closely to be fitted on the oriention benchmark face, guarantees that moving-member accurately moves along the oriention benchmark guide rail all the time reposefully.
The adaptive directed device of the utility model is because butterfly spring pretension expansive force is flexible, and guider can automatically adapt to the guide rail depth of parallelism, the overproof influence of linearity, guarantees steering capability in real time, prevents main spindle box obliquity effects machine finish.
This device is installed at guiding place at moving-member; Can improve steering capability and precision significantly for moving-member provides rational adaptive directed confining force, prevent main spindle box obliquity effects machine finish; Its good manufacturability; Low cost of manufacture, dependable performance has good economic and social benefits.
