Abstract
The invention discloses an elastic inlaid strip structure for eliminating a gap between sliding guide rails. The elastic inlaid strip structure for eliminating the gap between the sliding guide rails is characterized in that an elastic body which has certain rigidity is installed between the sliding guide rails, and the elastic body can be composed of a structure specially designed for a spring or an inlaid strip. A load is exerted on the elastic body through a fastening screw, so that controllable sliding guide rail pre-tightening force is provided, and it is guaranteed that the movable guide rail is completely attached to a fixed guide rail through the elastic inlaid strip structure during work and the pre-tightening force is constant. Compared with the prior art, the elastic inlaid strip structure for eliminating the gap between the sliding guide rails has the advantage that the movement precision of the sliding guide rails is improved on the premise that the structures of existing machine tool guide rails are not changed.
Description
Technical field
The present invention is a kind of elasticity panel structure eliminating rail plate gap, belongs to the technical field of structures of product.
Background technology
In field of machine tool equipment, rail plate is modal motion structure, for reducing the difficulty of processing of guide rail, ensure kinematic accuracy and the carrying of guide rail simultaneously, all pass through additional panel between two sliding pairs at present, as shown in Figure 1, the operation principle of this kind of structure is insert in rail plate A by panel B, hold out against panel B in the tight pit utilizing trip bolt C to screw in A, and leave a small―gap suture and ensure that rail plate A moves flexibly.In this structure, panel is all solid high stiffness structure, and guide clearance cannot be eliminated completely, and pretightning force is also wayward.When pretightning force is excessive, guide rail may move astringent even stuck, and when pretightning force is too small, guide clearance is bigger than normal affects kinematic accuracy.
Summary of the invention
The present invention designs for above-mentioned the deficiencies in the prior art just and provides a kind of elasticity panel structure eliminating rail plate gap, its objective is the kinematic accuracy improving rail plate under the prerequisite not changing existing sliding rail structure.
The object of the invention is to be achieved through the following technical solutions:
This kind eliminates the elasticity panel structure in rail plate gap, elasticity panel (3) is set between rail plate (1) and fixed guide (2), the stationary plane (6) of elasticity panel (3) is fixed on is connected on fixed guide (2) by the screw (4) that holds out against be arranged on fixed guide (2), hold out against screw (4) to hold out against screw (4) top compression elasticity panel (3) sliding surface of elasticity panel (3) (7) and rail plate (1) are adjacent at fixed guide (2) upper screwed hole (5) by screwing through processing, it is characterized in that: between two sides (8) between the stationary plane (6) and sliding surface (7) of elasticity panel (3), this side (8) is parallel with the glide direction of elasticity panel (3), process one or more groove arranged in parallel (9).
The shape of the cross section (10) of described groove (9) is circular, oval, square, rectangle, and this cross section (10) is parallel with two sides (8).
On the vertical cross-section (11) of described groove (9), the percentage that cavity area (12) accounts for cross section (11) is 50% ~ 80%, and this vertical cross-section (11) is vertical with the glide direction of elasticity panel (3).
Elasticity panel (3) is divided into two parts processing so that processing and assembling along the median plane (13) of two sides (8), and this median plane is parallel with the glide direction of elasticity panel (3).
The traditional rail plate panel pretightning force of structural change of the present invention applies the defect that uncontrollable and guide clearance can not be eliminated completely, eliminate because the existence of guide clearance and the irregular of pretightning force are on the impact of guide rail movement performance, reach and give full play to the machining accuracy limit, improve the object of equipment performance.
The advantage of technical solution of the present invention is:
One, this device utilizes the elastic deformation force of elasticity panel (2) elastomer portion, compresses rail plate, eliminates gap completely, and ensures rail plate not by dieback, flexibly mobile.
Completely eliminate the gap that existing rail plate exists, really accomplished zero clearance motion, improve the kinematic accuracy of rail plate;
Two, this device ensure that the constant of rail plate pretightning force, improves the dynamic characteristic of rail plate.

Detailed description of the invention
Below with reference to drawings and Examples, technical solution of the present invention is further described:
Shown in accompanying drawing 2 ~ 8, this kind eliminates the elasticity panel structure in rail plate gap, elasticity panel (3) is set between rail plate (1) and fixed guide (2), the stationary plane (6) of elasticity panel (3) is fixed on is connected on fixed guide (2) by the screw (4) that holds out against be arranged on fixed guide (2), hold out against screw (4) to hold out against screw (4) top compression elasticity panel (3) sliding surface of elasticity panel (3) (7) and rail plate (1) are adjacent at fixed guide (2) upper screwed hole (5) by screwing through processing, it is characterized in that: between two sides (8) between the stationary plane (6) and sliding surface (7) of elasticity panel (3), this side (8) is parallel with the glide direction of elasticity panel (3), process one or more groove arranged in parallel (9).
The shape of the cross section (10) of described groove (9) is circular, oval, square, rectangle, and this cross section (10) is parallel with two sides (8).
On the vertical cross-section (11) of described groove (9), the percentage that cavity area (12) accounts for cross section (11) is 50% ~ 80%, and this vertical cross-section (11) is vertical with the glide direction of elasticity panel (3).
Elasticity panel (3) is divided into two parts processing so that processing and assembling along the median plane (13) of two sides (8), and this median plane is parallel with the glide direction of elasticity panel (3).
Its material of elasticity panel of the present invention can be the metal material such as steel or copper, its implementation have integral type with split type, so-called integral type be panel be a part, process elastic characteristic thereon, so-called double-body bike refer to that panel is two parts, the formation entirety that is superimposed again uses, be mainly used for that space is less not easily adds man-hour, be divided into two easily processing, integral type be divided into hollow type, as shown in Fig. 3 ~ Fig. 5, the shape of its hollow out, can be rectangle and also can be other shapes, can determine according to different instructions for uses.Articulated as shown in Fig. 6 ~ Fig. 7, double-body bike mainly for the hollow type in integral type due to size restriction etc. be not easy process occasion be divided into two bodies processing, be superimposed together afterwards to use, as shown in Figure 8.The range in stiffness of final panel entirety is 5N-500N/um, and concrete rigidity value is determined according to the service condition of guide rail and size.
