Abstract
A linear guide rail for a machine tool comprises a guide rail connected with an apron through a bolt and a middle planker arranged above the guide rail, and is characterized in that a sliding block capable of driving the middle planker to move along the guide rail is arranged between the guide rail and the middle planker and is provided with a chute which is matched with the guide rail, and grooves having guiding functions are formed on the inner side wall of the chute and on the two side walls of the guide rail; and a gradient lock block connected with the apron through a bolt is arranged on the outer side of the guide rail. The utility model improves the manufacture precision and reduces the utilization cost.
Description
Technical field
The utility model relates to machining equipment, particularly a kind of lathe line slideway that can improve machining accuracy and reduce use cost.
Background technology
At present, guide rail on common level bed body and the numerically controlled lathe is generally flat guide, it is made of fixing and mobile two primary elements, but need intermediate medium between the moving meter of flat guide and the retaining element, this just makes, and coefficient of friction increases, make the forfeiture of machine tool guideway precision after the saddle wearing and tearing in the machine tool; Thereby the machine that has reduced lathe adds performance and the serviceability of itself.
In sum, the deficiency that exists of the track-type facilities of prior art is: the maintenance cost height, can not guarantee common level bed body lathe and machining accuracy of NC machine tool and use cost height for a long time.
Summary of the invention
The purpose of this utility model is in order to overcome the prior art above shortcomings, a kind of lathe line slideway that can improve machining accuracy and reduce use cost to be provided.
The technical solution adopted in the utility model is such, and promptly a kind of lathe line slideway comprises by bolt connecting at the guide rail on the saddle and being arranged on middle carriage above the guide rail; It is characterized in that: be provided with between described guide rail and middle carriage and can drive the slide block that middle carriage moves along guide rail, described slide block has chute and cooperates with guide rail, has the groove as guiding usefulness on described chute madial wall or the guide rail two side; In the outside of guide rail, be provided with by bolt and be connected gradient briquetting on the saddle.
The advantage that the utility model has owing to said structure is conspicuous:
1, improved horizontal linearity, the rigidity of upper slide rest and precision;
2, make traverse feed frictional force even, can prevent creeping phenomenon;
3, improve dimensional accuracy, reduced the part roughness;
4, not easy to wear, reduce maintenance and can make equipment keep machining accuracy for a long time;
5, guide rail protection and billows are sliding improves greatly.
Description of drawings
1
The utility model said structure can further specify by the non-limiting embodiment that accompanying drawing provides.
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing: 1, middle carriage; 2, slide block; 3, guide rail; 4, gradient briquetting; 5, saddle; 6, groove.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to accompanying drawing 1, the line slideway device of the lathe among the figure comprises by bolt connecting at the guide rail on the saddle 53 and being arranged on middle carriage 1 above the guide rail 3; Wherein: be provided with between described guide rail 3 and middle carriage 1 and can drive the slide block 2 that middle carriage 1 moves along guide rail, described slide block has chute and cooperates with guide rail, has the groove 6 as guiding usefulness on described chute madial wall or guide rail 3 two sides; In the outside of guide rail 3, be provided with by bolt and be connected gradient briquetting 4 on the saddle 5.Gradient briquetting 4 can prevent that guide rail 3 is to the both sides feed.
In the said structure: described slide block chute two inboards are provided with the ball retainer of stationary balls and do the arc groove that is provided with on the steel ball of straight-line rolling, the guide rail 3 to the steel ball guiding.
In the said structure: the steel ball in the groove of described guide rail 3 and the slide block 2 in the ball retainer is a kind of motion mode that contacts of putting.
Described groove 6 is a straight-line groove.
Said structure is that the power input shaft drive middle carriage 1 of work like this moves, because middle carriage 1 is affixed with slide block 2, the steel ball in the slide block 2 in the ball retainer is done directed straight-line rolling in guide rail 3 grooves 6, and this has just realized the straight line traverse feed.The sensitivity that this also improves the machine tool system has reduced the resistance of motion, has prevented creeping phenomenon; And noise is low, increase service life, have good high speed performance and overweight load.Also, middle carriage 1 produces simultaneously friction because directly not contacting with saddle 5, can the abrading machine bed apparatus, reduced maintenance to equipment; Because the stress equalization of rolling friction can make machine tool guarantee machining accuracy for a long time.
In sum, the utility model can improve machining accuracy and reduce use cost.
