Description

A kind of improvement line slideway itself with positioning and pre-pressing function

Technical field

The present invention be a kind of new and improved straight line guide rail itself with positioning and pre-pressing function it is adaptable to Machine Manufacture, Food machinery, the field such as medical machinery, for solving the problems, such as the positioning during installation of actual production middle guide and precompressed.It is different from institute There is the construction of common rail, it is possible to achieve very easily positioning and precompressed are adjusted, and guide rail can be ensured relative to the peace on machine Dress face processing capacity is minimum the easiest.The guide rail of this kind of structure, can be greatly improved production efficiency, thus producing huge economy Benefit.

Background technology

Apply and have passed through more than 40 year in various line slideways mechanically till now from exploitation, and in line slideway also When not being developed, all X, Y, Z axis linear motions mechanically are all friction-type gliding motilities.The exploitation profit of line slideway With making such friction-type gliding motility be transformed to roller gliding motility, greatly reducing coefficient of friction, decrease power Loss.Therefore, line slideway becomes the necessary of all machineries in the world soon.

And the manufacturer of line slideway be distributed in all over the world, Bao Kuo China including European Countries, TaiWan, China, Korea Spro State, Japan and the U.S. etc., importer is also innumerable.

Before all machine applications line slideways, because its motion mode is friction-type, so in opposing machinery punching The aspect such as hit, shake, shaking more slightly better than line slideway.But the gliding motility of friction-type is purely to rely on extrinsic power to enter Row, so the electric energy that such motion mode expends is too big, less efficient.And the continuous expansion with mechanical volume, be So that each part perfection is agreed with, lead to the irrational event of mechanical realization to happen occasionally.

Be developed to solve these problems and apply is exactly the straight line approved and use by All Around The World now Guide rail.

But due to the unstability of its roller gliding motility, in the impact resisting machinery, vibrations, the ability side of shake Face is weaker, so we have invented many fixed forms and precompressed compound mode for this.

Now on the market the installation precompressed mode of all line slideways as shown in Fig. 1, Fig. 3, Fig. 5, Fig. 8, Figure 10.Our company A kind of ZL200720155353.4 of special permission also method therein at last（As Fig. 5）.This is the track deposited using base, square, spiral shell The structures such as nail and method from precompressed to locating surface that realize carrying out.

Above-mentioned this compound mode is by obtaining frictional force at 5-10 from Fig. 5, fixing bed body 5-3 in Figure 5 Make.Because the size of different guide rails is different, U is also different for Fig. 5 intermediate gap, and the locating piece 5-8 in Fig. 5 and screw The size of 5-9, in order to meet all of guide rail demand, also has its corresponding different size.

The screw association of script is followed general with principle, but the precompressed combination praised highly here is through expert's essence Close calculate and design, more intelligence and accurately.

Numerous companies continue 40 years production and application line slideways in the world, crossed roller guide rail and do not find this all the time The reason company's method as described in Figure 3, it is mainly them and does not try to thinking in production and use in guide rails assembling During how easily to carry out positioning and precompressed problem, and simply duplication without thinking and production.

In addition, user thinks that the product that supplier provides must be standard, so also not trying before use again Go to think deeply the mounting means how improveing existing guide rail.

The most basic compound mode of guide rail as shown in figure 12, screw T is screwed in and is pressed on counter sink H median surface 07, leads to Cross the parallel friction after compression to be fixed, but due to the impact of generation, shake, vibrations during mechanical movement, can lead Cause the possibility that screw T gets loose from the space of counter sink H.

In order to prevent such problem that gets loose, it is possible to use the solution as shown in Fig. 1, Fig. 3, Fig. 5, Fig. 8, Figure 10 is come Precompressed is carried out to it.

In order to guide rail precompressed, the mode carrying out Fig. 1, Fig. 3, Fig. 5 is less problematic in processing, but Fig. 8, Figure 10 Then there are many problems in processing in mode.

Because needing side is processed in the course of processing of Fig. 8, Figure 10, this is accomplished by processing two planes, so Processing both increased the time and also increased expense, further needed exist for large-sized numerical control milling device to be processed.

Due to the problems referred to above, we are pre- by selection Fig. 1, Fig. 3, Fig. 5 generally in the case that installing space is abundant Pressure compound mode, comes that only this face of installed surface in bed body is processed to track.

But in the case that construction and space do not allow, we would have to take the precompressed compound mode of Fig. 8, Figure 10.

And to take the precompressed compound mode of Fig. 8, Figure 10 it is necessary to process the side of workpiece as Figure 14, in order to right Side carries out drilling and tapping processing it would be desirable to by one light then tens of kilograms, heavy then several tons of part is carried out as shown in Figure 15 It is disposed vertically, or product is transported to complete on another numerical control milling equipment being specifically used to carry out side processing.

Solution

In order to solve the above problems, original precompressed pattern, the problem to avoid side is processed can only be changed.And Change the method for original precompressed pattern, then can only be realized by changing the pattern of guide rail.

As shown in Figure 12, the material of bed body 03 is cast iron, because the case hardness of Figure 12 middle orbit 05 and slide block 06 is relatively Low.05 and 06 vertical direction is processed, makes some special-shaped head counterbores with the conical surface are formed on track, using carrying The conical surface to extrude special-shaped head counterbore for the special-shaped head soket head cap screw of the conical surface, formed transverse translation power guide rail is carried out pre- Pressure；And the tapping then only carrying out on the installed surface of bed body 03 respective carter in vertical direction is processed, it is right so to avoid Bed body 03 carries out the problem of side processing, and also saves installing space.

But any company does not all find this point on the market.

So, we can carry out Drilling operation by the guide rail product depositing all bases, to save and above-mentioned bed body to be entered The problem of row side processing, the course of processing directly to be completed by guide rail supplier.

And guide rail supplier then can will carry out the line slideway after drilling and tapping processing and rolling wheel guide rails are divided into new kind Class earns a profit to sell, and expense extremely low producing in the course of processing（It is about 0.2% ~ 0.3%）, and the effect that it produces Fruit is but very good.

The ZL200720155353.4 of our company's special permission（As Fig. 5）Such issues that just can solve above-mentioned, but Simply in the case that installing space is abundant.

The processing of above-mentioned Fig. 1, Fig. 3, Fig. 5 mounting means is relatively simple, if the installation taking Fig. 8, Figure 10 of having to During mode, the technology of the present invention is exactly the optimal prediction scheme solving the complicated processing shown in Figure 14, Figure 15.

In order that with the mounting means of Fig. 8, Figure 10, it is accomplished by carrying out substantial amounts of low when being processed to parts such as bed body Efficiency works in addition it is also necessary to buy large-sized numerical control milling device, and high consumption is inefficient, so, reduce the expense in this work process With imperative with quantities.

Reduce quantities, single method to solve above-mentioned engineering roadblock from vertical direction processing installed surface has two kinds.First The method of kind is exactly the line slideway shown in Figure 16, and on its track 16-5, the special-shaped head counterbore H16 with the conical surface of processing can be fine Decompose the power that special-shaped head soket head cap screw T16 applies so that track 16-5 be subject to the effect of a cross force and to positioning Face 16-1 moves.This is also most representational method.

Second method, as shown in figure 22, is equally the mode using taper surface decomposing force, but, taper surface becomes Processing is in bed body 22-3, and carries out tapping processing to track 22-5；This mode, is also only a face of installed surface to be carried out Drilling operation, processing technique is also very simple；Its utilize existing standard screws, that is, the conical surface of tapered end holding screw T22 without a head with The conical surface of tapered blind hole H22 coordinates to realize extruding, thus carrying out precompressed to guide rail 22-5.

Above two mode, the principle of employing is all identical, does not exist together, and is merely only the processing pattern to guide rail and peace The processing in dress face has differences, and optimum mode can be selected in actual production as needed to be installed.

Specific embodiment

As shown in figure 16, processing profiled head counterbore H16 in orbit, processes screw hole in bed body installed surface corresponding position Q16, after guide rails assembling is on installed surface, special-shaped head soket head cap screw T16 passes through special-shaped head counterbore H16 and installed surface to tighten up a screw hole Q16 coordinates, because installed surface is tightened up a screw, hole Q16 is less than the distance away from locating surface 16-1 for the special-shaped head counterbore H16 so that in special-shaped head The conical surface of hex screw T16 is overlapped with the conical surface of special-shaped head counterbore H16 at A, by screwing in special-shaped head soket head cap screw T16, The conical surface of the special-shaped head counterbore H16 of extruding, makes track 16-5 move to locating surface 16-1 thus producing a cross force, right to reach Track 16-5 carries out the purpose of precompressed.

As shown in figure 22, sinking screw hole Q22 processed by track, at the sinking screw hole Q22 of respective carter on installed surface Processing conehead blind hole H22, a tapered end holding screw T22 without a head passes through sinking screw hole Q22, because sinking screw hole Q22 is more than The distance away from locating surface 22-1 for conehead blind hole H22 is so that the cone of the conical surface of tapered end holding screw T22 without a head and conehead blind hole H22 Face overlaps at C, by screwing in so that its end conical surface extrudes the conical surface of conehead blind hole to tapered end holding screw without a head, and Track is made to be subject to the effect of cross force to form precompressed.

As shown in figure 16；Slide block 16-6 pattern constant it is only necessary to workbench 16-4 corresponding position thereon, if processing Dry abnormity head counterbore H16, screw hole Q16 ' is more than the special-shaped distance away from locating surface 16-2 for the head counterbore H16 ', by special-shaped head Hex screw T16 ' DRIVE SCREWS hole Q16 ' so that the conical surface of special-shaped head soket head cap screw T16 ' extrude at B different on workbench The conical surface of forming head counterbore H16 ', the horizontal force that it produces makes slide block 16-6 be able to carry out precompressed on workbench 16-4.

As shown in figure 22, slide block 22-6 Surface Machining conehead blind hole H22 ', its bottom of workbench processing that slide block is installed Sinking screw hole Q22 ', conehead blind hole H22 ' it is more than the distance away from locating surface 22-2 for the sinking screw hole Q22 ', by tapered end without a head The screw-in of holding screw T22 ' is so that its end conical surface extrudes conehead blind hole H22 at D ' the conical surface, thus producing transversely acting Power to carry out precompressed to slide block 22-4.

Above-mentioned all of guide rail in the present invention, utilization is all that conical surface stress occurs the principle of transverse movement being positioned Precompressed, because the difference of guide rail construction itself is so that when being installed, only carry out to one face of installed surface of machine tool body Process, reduce processing cost, decrease process time, substantially increase production efficiency.Two kinds of different track perforates Precompressed mode and sliding block prepressing mode, use of can arranging in pairs or groups according to actual needs.The new and improved guide rail processing of this kind of structure is simple, Compact conformation, and regulating effect is good, cost performance is high, therefore, once releasing, will have large market prospect.
