Abstract
Disclosed is a ball screw compliance auxiliary supporting mechanism, which includes a pair of supporting components, a linear guide rail, a linear guide rail slider and a pair of connecting rods. The pair of supporting components is arranged on the guide rail through the linear guide rail slider and is connected with each other by the connecting rods. The auxiliary supporting mechanism has the advantages that the compliance auxiliary supporting mechanism is positioned between the two ends of the ball screw, so that the screw auxiliary supporting mechanism can move with a moving component of a machine tool for shortening the supporting distance of the screw, preventing the screw from sagging, ensuring the moving load and the positioning accuracy of the machine tool and prolonging the service life of the machine tool screw, resulting in an obvious effect in application.
Description
Technical field
The utility model relates to a kind of parts of lathe, particularly supports the mechanism of lathe ball-screw.
Background technology
Along with the development of domestic economy technology, the demand of machine industry is from simple type, popular to compoundization, precise treatment, maximization transformation, and especially in the energy, space flight, automobile, traffic, war industry's five big industries, this characteristics of demand is more apparent outstanding.A collection of large-scale precision numerical control gantry process equipment has appearred for this reason.But the structure of high accuracy linear guides and ball-screw kinematic pair is adopted in the increase of lathe specification, often runs into the sagging phenomenon such as serious in long ball-screw middle part, influences the transmission accuracy and the service life of leading screw.Because the stroke of large-sized gantry machining center is often all very big, consider the safe distance of stroke at leading screw two ends and the distance of support zone, leading screw length often will surpass more than a meter of stroke distances, and existing ball-screw only has the motor bracing or strutting arrangement of two ends and end support device to support, inevitable because the self gravitation in the middle part of ball-screw and sagging, cause the load and the positioning accuracy of machine tool motion overproof thus, the service life of also having reduced lathe.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art and a kind of ball-screw trailing type supplemental support mechanism is provided, and improves the transmission rigidity of machine tool lead screw and the purpose in service life thereby reach the support distances that shortens leading screw.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Ball-screw trailing type supplemental support mechanism is made up of a pair of supporting component, linear guides, linear guides slide block, pair of links, is connected by connecting rod between a pair of supporting component, and supporting component passes through the linear guides slider frame on guide rail.
Its linear guides was installed on the lathe when above-mentioned ball-screw trailing type supplemental support mechanism used, and its supporting component is enclosed within on the ball-screw of lathe.
Compared with prior art, advantage of the present utility model is:
By between the ball-screw two ends, increasing the supplemental support mechanism of trailing type; leading screw supplemental support mechanism can be moved along with moving of machine tool motion component; thereby shorten the support distances of leading screw effectively; guarantee that leading screw is not sagging; guarantee the load and the positioning accuracy of machine tool motion; prolonged the service life of machine tool lead screw, effect is obvious in actual applications.

Fig. 1 is the vertical view of the utility model embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the enlarged drawing of the B part of Fig. 2.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the original ball-screw 20 of lathe supports 40 by the motor bracing or strutting arrangement 10 and the end support device of two ends.
Ball-screw trailing type supplemental support mechanism is set between existing bracing or strutting arrangement, it is made up of a pair of supporting component 3, linear guides 4, linear guides slide block 5, connecting rod 8, connected by connecting rod 8 between a pair of supporting component 3, supporting component 3 on guide rail 4, is seen Fig. 3 by 5 of linear guides slide blocks.
To the injuries such as wearing and tearing of ball-screw, be provided with in the above-mentioned supporting component 3 from profit cover 1 when moving in order to overcome supplemental support mechanism, profit cover 1 is enclosed within on the ball-screw 20 certainly.
In order to keep highly consistent, therefore establish adjusting pad 6 at supporting seat 3 and 5 of slide blocks, see Fig. 3.
Four anticollision blob of viscoses 7 have been designed at above-mentioned supporting component 3 inside and outside two ends, damage when preventing the collision of trailing type supplemental support mechanism.
When ball-screw trailing type supplemental support mechanism uses, its supporting component 3 is enclosed within on the leading screw 20, linear guides 4 is fixed on the bed piece 9, therefore whole supporting mechanism can move on linear guides 4 along with moving of ball-screw nut 2, thereby guarantee that a pair of supporting component 3 effectively supports ball-screw 20 all the time, prevent that ball-screw 20 is because of oversize sagging in the centre.
