Abstract
The invention relates to the technical field of screw rod fixing bases, in particular to a machine tool screw rod fixing base. The machine tool screw rod fixing base is provided with a square base body. The base body is provided with an installation groove. A main body is fixedly installed in the installation groove. A screw rod shaft hole used for installing a screw rod is formed in the center of the main body. A ball bearing is arranged on the screw rod in a sleeving mode and located in the screw rod shaft hole. A bearing sleeve is arranged between the inner wall of the screw rod shaft hole and the outer wall of the ball bearing. A fixing cover plate is arranged on the upper portion of the main body. Longitudinal installation holes are formed in the base body. Axial installation holes are formed in the main body. The machine tool screw rod fixing base is reasonable in design and provided with the ball bearing, and the lubricating property of the machine tool screw rod fixing base is improved; due to the fact that the machine tool screw rod fixing base is provided with the longitudinal installation holes, the fixing base and a machine tool are steadily installed, and the screw rod has the stable moving property. The whole machine tool screw rod fixing base is resistant to abrasion and long in service life.
Description
Technical field
The present invention relates to leading screw holder technical field, be especially a kind ofly installed on machine tool lubrication performance and the excellent machine tool lead screw holder of transmission performance.
Background technology
Leading screw is that gyration is converted into rectilinear motion, or is the device of gyration by transform linear motion.As the transmission device of lathe, lead screw transmission has irreplaceable effect, and therefore leading screw holder also has very important status.Traditional leading screw fixed seat structure is complicated, and install and keep in repair loaded down with trivial details, precision and stationary performance are all not high, and anti-wear performance is poor, and greasy property is also bad, and need often maintenance or change, service life is low, reduces production efficiency, improves production cost.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of structure simple, greasy property and the excellent machine tool lead screw holder of transmission performance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of machine tool lead screw holder, there is plinth, base offers mounting groove, mounting groove internal fixtion is provided with main body, described main center offers the screw mandrel axis hole installed for screw mandrel, be provided with the ball bearing be set on screw mandrel in screw mandrel axis hole, between screw mandrel shaft hole inner wall and ball bearing outer wall, be provided with bearing holder (housing, cover), above described main body, be provided with securing cover plate; Described base is provided with the longitudinal installing hole be fixed on by machine tool lead screw holder on lathe, main body offers axial installing hole main body be connected with base.
Further, described ball bearing two ends are provided with gasket seal.
Further, the part contacted between described base and main body is provided with pad.
Further, described body thickness is greater than the thickness of base.
The invention has the beneficial effects as follows: the present invention is reasonable in design, be provided with ball bearing, improve the greasy property of machine tool lead screw holder, be provided with longitudinal installing hole, holder and lathe stablized and installs, make screw mandrel have stable exercise performance, whole machine tool lead screw holder is wear-resisting, long service life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. main bodys in figure, 2. screw mandrel axis hole, 3. bearing holder (housing, cover), 4. ball bearing, 5. gasket seal, 6. securing cover plate, 7. longitudinal installing hole, 8. axial installing hole, 9. base.
Detailed description of the invention
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of machine tool lead screw holder as shown in Figure 1, there is plinth 9, base 9 offers mounting groove, mounting groove internal fixtion is provided with main body 1, main body 1 center offers the screw mandrel axis hole 2 installed for screw mandrel, be provided with the ball bearing 4 be set on screw mandrel in screw mandrel axis hole 2, between screw mandrel axis hole 2 inwall and ball bearing 4 outer wall, be provided with bearing holder (housing, cover) 3, above main body 1, be provided with securing cover plate 6; Base 9 is provided with the longitudinal installing hole 7 be fixed on by machine tool lead screw holder on lathe, main body 1 offers the axial installing hole 8 main body 1 be connected with base 9.
Ball bearing 4 two ends are provided with gasket seal 5; The part contacted between base 9 and main body 1 is provided with pad; Main body 1 thickness is greater than the thickness of base 9.
This machine tool lead screw fixed seat structure is simple, reasonable in design, be provided with ball bearing, improve the greasy property of machine tool lead screw holder, be provided with longitudinal installing hole, holder and lathe stablized and installs, make screw mandrel have stable exercise performance, whole machine tool lead screw holder is wear-resisting, long service life.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
