Description
Technical field
The present invention relates to high-precision, high rigidity prestressing force bearings, belong to precision equipment manufacturing technology field.
Background technology
In precision equipment manufacturing technology field, in high-precision digital control Machine Manufacture, ball-screw both ends in feed system
The screw mounting base of bearing and roller screw be planar screw connection structure, frictionally equilibrium reaction, there are rigidity not
The problems such as foot, precision be not high, positioning is unstable, causes that system accuracy is low, repetitive positioning accuracy is unreliable.
The content of the invention
In order to overcome since insufficient rigidity existing for bearing and precision be not high in above-mentioned feed system, caused system is determined
The problems such as position precision is low, repetitive positioning accuracy is unreliable, the present invention provides a kind of high-precision, high rigidity prestressing force bearings, fit
For precision machine tool feed drive system, there is simple in structure, positioning accuracy and connection height height, good reliability.
The technical solution adopted in the present invention is a kind of high precision high rigidity prestressing force bearing, which is：Bearing
Body (1) is the agent structure of the high precision high rigidity prestressing force bearing, and bearing body (1) is special-shaped structural part；Bearing body (1) it is upper
Portion is equipped with driving mechanism mounting hole (9)；Mounting screw holes b (3) and mounting screw holes c (4) is separately positioned on the two of bearing body (1)
Side；Screw b (13) is installed on mounting screw holes b (3), screw c (14) is installed on mounting screw holes c (4), makes bearing body
(1) it is mounted on mechanical body part (16)；It is oblique that the lower part of bearing body (1) is equipped with installation faying face (5), positioning surface (6), prestressing force
Face (7) and mounting screw holes a (2), installation faying face (5) are arranged vertically with positioning surface (6), installation faying face (5) and positioning surface
(6) it is cascaded surface；Mounting screw holes a (2) is connected by screw a (12) with mounting screw holes d (11), make bearing body (1) with tiltedly
Key (8) is connected, and prestressing force inclined-plane (7) is made to be in contact with wedge surface (10), and wedge surface (10) is used for reinforcement, improves bearing body installation
Prestressing force；Taper key (8) is wedge structure, and side (15) are parallel with positioning surface (6) and are in contact with mechanical body (16), play
Positioning action.
Compared with prior art, the present invention has the advantages that.
This seat structure is suitable for precision machine tool feed drive system, has simple in structure, easy to operate, positioning accuracy
The advantages that high, connection height height, good reliability, practicability is very strong.

Specific embodiment
As shown in Fig. 1 Fig. 2 Fig. 3, bearing body (1) is special-shaped structural part, and its upper part is equipped with driving mechanism mounting hole (9), under
Portion be equipped with the faying face (05), positioning surface (6), prestressing force inclined-plane (7) and mounting screw holes of mechanical body (16) installation (2,3,
4) it is used for mounting screw (12,13,14) hold-down support body；Taper key (8) is wedge structure, and one side (15) is for positioning, wedge
The prestressing force of bearing body installation is improved in face (10) for reinforcement, equipped with mounting screw holes (11) for mounting screw (12), tension
Taper key reaches reinforcement pretensioning effect.
In use, bearing body (1), taper key (8) and mounting screw (12,13) are formed component, mechanical body is pre-installed in
In the mounting groove of part (16), prefastened screw (13,12,14) examines the installation accuracy of driving mechanism mounting hole (4) to meet the requirements
Afterwards, trip bolt (13,14), and trip bolt (12) again again pull taper key (8), realize inclined plane force increasing, in advance should realize
Power.Meet high-precision, the installation requirement of high rigidity, reach positioning accuracy height, connect the highly high, performance of good reliability.
