Abstract
The utility model relates to the technical field of a screw rod bearing installation of a numerical control machine tool, and particularly relates to a bearing sleeve device. The bearing sleeve device comprises a bearing seat, a bearing sleeve, a spacer bush, lock nuts, a bearing, a bearing cover and a screw rod shaft. The spacer bush is sleeved on the outer side of the screw rod shaft. The lock nuts are evenly arranged at two ends of the spacer bush to lock. The bearing seat is arranged at the periphery of the spacer bush. The bearing sleeve is arranged on the bearing, and the bearing cover is arranged at the tail end of the bearing sleeve to compact. According to the structure of the bearing sleeve device, the part, namely the bearing sleeve is additionally arranged, so that the structure of the device is simple, machining is convenient, and installation is compact, therefore, the needed accuracy is guaranteed in an installation process, and at the same time, installing convenience of operators is also met.
Description
Technical field
The utility model relates to numerical control machine tool screw mandrel bearing mounting technique field, especially a kind of bearing sleeve device.
Background technique
At present, known numerical control machine tool leading screw bearing is comprised of bearing support, bearing, gland.When the leading screw High Rotation Speed, very high to the required precision of installing positions of bearings, by inquiry bearing sample as can be known, it is Ra0.8 that bearing is installed surface roughness, and general right boring or finish-milling can only reach Ra1.6; And the perpendicularity that end face and bearing axis are installed can reach 0.005mm; Type position tolerance also can reach the H6 level.When installing, scrape the bearing housing end face by shovel and adjust the concentric of bearing axis and leading screw axis.Like this, general bearing needs to solve the problem that exists in structural configuration is installed, and satisfies operator convenience is installed in order to guarantee necessary precision.
The model utility content
Not up to standard for the precision that overcomes existing numerical control machine tool high-speed guide screw bearing attachment face, easily cause operation accident and operator to bring the problems such as inconvenient, the utility model provides a kind of bearing sleeve device.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of bearing sleeve device, comprise bearing support, bearing housing, spacer, locking nut, bearing, bearing gland and screw axis, screw axis outside cover has spacer, the spacer two ends are equipped with locking nut locking, spacer is arranged with bearing support outward, on the described bearing bearing housing is installed, the bearing housing end is provided with bearing gland and compresses.
The beneficial effects of the utility model are, have increased the shaft parts bearing sleeve in the utility model structure, and are simple in structure, easy to process, install compactly, guaranteed the precision that needs in installation process, also satisfied operator simultaneously convenience is installed.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Wherein, 1, bearing support, 2, bearing housing, 3, spacer, 4, locking nut, 5, bearing, 6, bearing gland, 7, lead screw shaft.
Embodiment
Structural representation of the present utility model such as Fig. 1, a kind of bearing sleeve device, comprise bearing support 1, bearing housing 2, spacer 3, locking nut 4, bearing 5, bearing gland 6 and screw axis 7, screw axis 7 outsides cover has spacer 3, spacer 3 two ends are equipped with locking nut 4 lockings, be arranged with bearing support 1 outside the spacer 3, on the described bearing 5 bearing housing 2 be installed, bearing housing 2 ends are provided with bearing gland 6 and compress.
During installation, first bearing housing 2 is installed on the bearing 5, at installation shaft pressure cap 6.Then scrape by shovel and end face is installed so that bearing axis is concentric with the leading screw axis, the more original structure of this installation is more convenient.
Increased the part bearing sleeve in the utility model structure, simple in structure, easy to process, compactness is installed, in installation process, guaranteed the precision that needs, also satisfied operator simultaneously convenience has been installed.
