Description

Novel mechanical guide rail and guide rail assembly

Technical Field

The invention belongs to the technical field of high-speed motion platforms, and particularly relates to a novel mechanical guide rail and a guide rail assembly.

Background

The mechanical guide rail type motion platform is widely applied to industrial equipment such as electronic manufacturing, laser processing, precise detection, ink-jet printing and the like due to high acceleration performance.

As shown in fig. 1, fig. 1 is a high-speed high-precision mechanical guide rail in the prior art. Fig. 1 shows a rail body 10A, a base 20A, and a slider 30A. The rail body 10A is provided on the base 20A for fixing the rail 10A. The slide block 30A is slidably disposed on the guide rail 10A, and is used for driving a moving platform (not shown in the figure) to move on the guide rail 10A. The guide rail 10A is uniformly provided with through holes 109A, the base 20A is provided with mounting holes 201A corresponding to the through holes 109A, and the bolts 40A pass through the through holes 109A and are inserted into the mounting holes 201A, so that the guide rail 10A is fixed to the base 20A.

In the existing mechanical guide-rail type motion platform, the motion speed of the guide rail is generally within 10m/s, and usually about 5m/s, which belongs to the high-speed motion platform category of the existing products. For such high-speed moving platforms, the guide rails are required to bear loads in multiple directions such as bending, torsion, tilting and the like, and the guide rails are usually made of high-rigidity materials. Due to the high rigidity of the guide rail, under the current movement of about 10m/s, the through holes formed in the surface of the guide rail have little fluctuation to the speed of the sliding block, so that no one notices that the through holes formed in the surface of the guide rail can cause the fluctuation of the speed of the sliding block, and no one notices what the specific influence is.

The inventor of the application is dedicated to research on a high-speed or even ultra-high-speed high-precision motion platform, and finds that the through hole formed in the surface of the guide rail can cause the speed fluctuation of the sliding block for the first time, and the larger the speed of the sliding block is, the larger the speed fluctuation caused by the through hole is. When the slider is operated at very high speeds, for example, above 10m/s, this speed fluctuation is so significant that it cannot be ignored, and it is necessary to improve the guide rail structure to reduce or avoid this speed fluctuation.

Based on the initial discovery, under the unified design idea, the inventor designs a series of novel mechanical guide rails so as to be suitable for a high-speed and ultrahigh-speed high-precision motion platform.

Disclosure of Invention

The inventor firstly finds that excitation load frequency f is generated on the sliding block by uniformly distributed holes of the guide rail, and the calculation formula is as follows:

f＝v/l

wherein v is the moving speed of the slide block, and l is the distance between the adjacent through holes on the guide rail. In the experimental process, we found that in some test examples, when the moving speed of the slide block is 1m/s, the excitation can cause the speed fluctuation to be about 0.6 percent, and is very small and can be ignored. However, when the speed is increased to 5m/s, the fluctuation reaches about 2%, and for equipment with speed fluctuation limitation, such as an ink-jet printer, a laser dicing saw and the like, the speed fluctuation causes the platform to be incapable of working normally.

The technical solution of the present invention is described in detail with specific examples below.

Referring to fig. 2A-9B, the present application provides a novel mechanical guide rail for mounting a slider 30 to slide the slider 30 on the guide rail, the guide rail includes a guide rail body 10, and the guide rail body 10 is fixed on a base 20. The rail body 10 includes: a first surface 101, and second and

third surfaces

102 and 103. Generally, the second surface 102 and the third surface 103 are substantially mirror-symmetrical structures, which facilitates fabrication into standard parts and also facilitates machining.

The first surface 101 faces the slider 30. There is a certain gap between the first surface 101 and the slider 30 for air to flow. When the slider 30 slides on the rail body 10, air is entrained to flow between the first surface 101 and the slider 30.

The second and

third surfaces

102 and 103 are adjacent to the first surface 101, and the second and

third surfaces

102 and 103 are provided with a protruding portion 105 at a position away from the base 20, wherein the protruding portion 105 is used for mounting a rolling component (not shown) in the slider 30.

The fixing of the rail body 10 to the base 20 ensures that the rail body 10 is free of voids in the positions facing the slider 30 and contacting the slider 30.

The guide rail structure design without the holes effectively avoids speed fluctuation caused by the installation of the guide rail on the base, improves the precision of the motion platform, and ensures that the novel mechanical guide rail is particularly suitable for the ultrahigh-speed high-precision motion platform.

In one embodiment of the present application, as shown in fig. 2A and 2B, the boss 105 has a mounting curved surface 106, and the mounting curved surface 106 is matched with the surface of the rolling member to form surface contact. The surface contact between the rail body 10 and the rolling parts in the slider 30 can significantly improve the rigidity of the rail, and is more suitable for high-precision motion platforms, because the rail needs to bear various loads such as bending, torsion, tilting and the like. As shown in fig. 2B, for the left and right convex portions 105, each convex portion 105 is provided with 2 mounting curved surfaces 106. This applies to the case where the slider 30 includes two rows of upper and lower rolling elements. If the slider 30 has only a single row of rolling elements, only one curved mounting surface 106 is required. It should be understood that those skilled in the art can design the number of the mounting curved surfaces 106 and adjust the shape of the curved surfaces according to the actual requirement, and the invention is not limited thereto.

In one embodiment of the present application, as shown in fig. 2A and 2B, the second and

third surfaces

Further, in one embodiment of the present application, as shown in fig. 2A and 2B, the rail body 10 is directly welded to the base 20. As shown in fig. 2B, the right-angled triangle marks in the figure indicate the welding points between the rail body 10 and the base 20. Through the welding mode, just can not form any hole on the guide rail body 10, the rigidity is very high, is particularly suitable for the high accuracy motion platform of ultrahigh speed.

In one embodiment of the present application, as shown in fig. 3A and 3B, the rail body 10 is integrally formed with the base 20. The guide rail body 10 and the base 20 are integrally formed to form an inseparable whole, and the guide rail body 10 does not need additional installation operation or additional installation parts. This structure not only makes it possible to realize a position where the rail body 10 faces the slider 30 and contacts the slider 30 without a void, but also is very simple in structure.

In one embodiment of the present application, as shown in fig. 4A and 4B, the guide rail further includes a bolt 40, and the second and

The rail body 10 further includes a fourth surface 104, the fourth surface 104 being opposite to the first surface 101 and being in contact with the base 20. In a preferred embodiment of the present application, the bottom surface of the mounting portion 108 is coplanar with the fourth surface 104. With this structure, it is also possible to avoid forming holes on the surface of the rail 101 and to maintain the detachable connection of the rail body 10 and the base 20. As shown in fig. 4B, a flat washer 401 and a spring washer 402 may be further provided under the bolt 40 to ensure the tightness of the connection, which is common knowledge in the art, and may be omitted from subsequent views for the sake of clarity and convenience in reading.

In the guide rail shown in fig. 5B, the mounting portion 108 is a slope extending from the second and

third surfaces

102 and 103 toward the base 20, and the pressing piece 50 has a slope matching the slope, and the slope of the pressing piece is positioned above the slope of the guide rail body 10, thereby pressing the guide rail body 10 against the base.
