Abstract
The utility model discloses a dovetail-shaped guide rail pair of a high-precision machine tool, which comprises a dynamic guide rail and a static guide rail. The top part of the static guide rail is a continuous plane; circular beads at the two sides of the static guide rail also adopt planes which are arranged in parallel to the top plane; the dynamic guide rail is matched with the part of the static guide rail above the circular beads; the dovetail-shaped angle formed by the dynamic guide rail and the static guide rail is 50 to 70 degrees; the bearing surface of the static guide rail is completely pasted with a polytetrafluoroethylene soft belt; and the static guide rail is provided with a lubricating oil groove and an oil hole. The utility model has the advantages of increasing the load bearing capacity of the whole static guide rail, greatly reducing the friction between the dynamic guide rail and the static guide rail, effectively preventing the jitter caused by the low-speed creeping and the high-speed operation, significantly improving the performance of maintaining the guiding precision and the operational accuracy of the guide rails, and also remarkably prolonging the service life of the guide rail pair.
Description
Technical field
The utility model relates to the guide rail on the lathe, particularly a kind of dovetail slideway.
Background technology
Guide rail on the lathe is to guarantee in the machining equipment that driving member or movement parts move and bear the supporting and the accurate guiding mechanism of load on the movement parts along certain straight line or circular path.Because during lathe work, the moving guide rail of carrying workbench is along quiet guide rail movement, ubiquitous each other slip or rolling friction meeting are worn and torn the spigot surface of guide rail and loading end gradually and are produced bigger gap, therefore influence the maintenance performance of guiding accuracy, reduce the machine finish grade.The principal element that influences way rub has guide rail cross sectional shape, force-bearing situation, guide material and processing technology, lubricated and means of defence etc.Existing guide rail cross section basic configuration has rectangle, triangle and swallow-tail form etc., and wherein rectangular guideway processing is easy to maintenance, and bearing capacity is bigger, but spigot surface mainly is the side, and the wearing and tearing back produces big gap, influences guiding accuracy; The apex angle of triangular guide changes in 90 ° ± 30 ° scopes, the guiding accuracy height that drift angle is little, but frictional force is big, easily is worn, and service life is also shorter, and the bearing capacity that drift angle is big is big, but guiding accuracy reduces; The maximum characteristics of dovetail slideway are highly less, can bear disturbing moment, are easy to the adjusting play, be used for multi-coordinate multiple benches platform, but it are complex-shaped, and difficulty is repaired in processing, and rigidity is relatively poor.
The utility model content
The purpose of this utility model is to overcome the deficiency of existing guide rail technology, the dovetail slideway pair of the high precision machine tool that propose that a kind of bearing capacity is big, guiding accuracy is high, self lubricity, good operation stability is arranged.
The technical scheme that realizes above-mentioned purpose is: the dovetail slideway pair of high precision machine tool, comprise moving guide rail and quiet guide rail, and the top of described quiet guide rail is a continuous level, the shoulder of both sides also is the plane, and parallel with top plan; Described moving guide rail and described quiet guide rail shoulder match with the upper part, dovetail angle on moving guide rail and the quiet guide rail is 50 °～70 °, be pasted with the soft PTFE ribbon of thick about 3mm on the stress surface of quiet guide rail comprehensively, evenly be added with the bronze powder high-abrasive material in the soft band; On the circular bead surface of described quiet guide rail both sides oil-way is arranged respectively one, the bottom of described each oil-way is separated with a plurality of oil transportations hole between all, and the oil transportation hole on each face is interconnected, and is connected with outside petroleum pipeline.
An optimal technical scheme of the present utility model is: the dovetail angle on described moving guide rail and the quiet guide rail is 60 °.
Another optimal technical scheme of the present utility model is: described oil-way is a multistage linear pattern oil groove, and forms the continuous shape of a kind of setback, and described oil transportation hole is positioned at the bottom of each flex point.
The advantage of the dovetail slideway pair of the utility model high precision machine tool is: 1. the both sides shoulder of a quiet guide rail part of also carrying moving guide rail, and the bearing capacity of whole quiet guide rail increases; 2. be pasted with the very little soft band of wear-resisting polytetrafluoroethylplastic plastic of coefficient of friction on the stress surface of quiet guide rail comprehensively, and dynamic and static guide rail can pass through oil lubrication again, this has just reduced friction greatly, effectively prevented the phenomenon that generation low speed jerking motion and high-speed cruising are easily beated, and increased substantially the maintenance performance of the guiding accuracy and the running precision of guide rail, also prolonged the service life of track pair greatly.
Description of drawings
Fig. 1 is the utility model global sections schematic diagram.
Fig. 2 is the schematic cross-section of the moving guide rail of the utility model.
Fig. 3 is the schematic cross-section of the quiet guide rail of the utility model.
Fig. 4 is that the A of Fig. 3 is to the half-twist schematic diagram.
Among the figure: 1. moving guide rail, 2. quiet guide rail matrix, the 3. soft band of polytetrafluoroethylplastic plastic, 4. oil-way, 5. oil transportation hole.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The utility model guideway is swallow-tail form (as Fig. 1, Fig. 2 and shown in Figure 3).Moving guide rail 1 and quiet guide rail matrix 2 all are processed into HT25-40 casting pig, and adopt manual scraping fine finishining, reach its high-precision requirement.
The top of quiet guide rail matrix 2 is a continuous level, the shoulder of its both sides also is the plane, and it is parallel with top plan, dovetail angle α is 60 ° and (all can for 50 °～70 °, 60 ° is an optimized angle), paste List has the soft PTFE ribbon 3 (as shown in Figure 3) of thickness 3mm on two side planes between top plan, shoulder plane and the top and the shoulder of quiet guide rail matrix 2, and soft being with evenly is added with the bronze powder high-abrasive material in 3.
Moving guide rail 1 matches with the upper part shape with quiet guide rail shoulder, and each contact-making surface matches, and forms each other to be slidingly matched (as depicted in figs. 1 and 2).Can be clear that from Fig. 1 moving guide rail is being carried at the top that is not only quiet guide rail, the dovetail lower end of moving guide rail is dropped on the both sides shoulder of quiet guide rail, and the both sides shoulder of quiet guide rail is also carrying the part of moving guide rail.
On the circular bead surface of quiet guide rail both sides one oil-way 4 (as shown in Figure 4) arranged respectively, this oil groove is not with 3 to cover by soft, and the bottom of each oil-way is separated with a plurality of oil transportations hole 5 between all; On two medial surfaces of moving guide rail 1 a plurality of oil transportations hole 5 is arranged respectively, the oil transportation hole 5 on each face is interconnected, and is connected (as shown in Figures 2 and 3) with outside petroleum pipeline.Generally speaking.Shown in Fig. 4 is the shape schematic diagram of the lubricating oil sump of an embodiment, is a kind of multistage straight wave fold-type continuous lubrication oil oil groove, and oil transportation hole 5 is positioned at the bottom of each setback flex point.Certainly, the shape of oil groove is not limited thereto, and can also be other shapes such as waveform.
