The V-shaped roller guide rail pair combines the advantages of a rolling linear guide rail and a V-shaped sliding guide rail, and solves the problems that the existing rolling linear guide rail is poor in vibration resistance and a sliding flat key is not suitable for high-speed movement.

Description

V-shaped roller guide rail pair

Technical Field

The invention relates to a sliding guide rail in a high-precision grinding machine.

Background

At present, a rolling linear guide rail or a V-shaped sliding guide rail is often adopted as a common automatic equipment guide rail, the rolling linear guide rail adopts a circulating roller or a ball to move, and has the characteristics of high precision and high speed, but in some application fields, such as a high-precision grinding machine, a machine tool needs to have good vibration resistance, after the rolling linear guide rail is used for a period of time, the rigidity is reduced due to abrasion, the vibration resistance is reduced, and vibration lines appear on a processed product. The V-shaped sliding guide rail can be well attached even if the contact surface of the V-shaped sliding guide rail is abraded, and the rigidity of the V-shaped sliding guide rail cannot be reduced, so that the V-shaped sliding guide rail has good vibration resistance, but the V-shaped sliding guide rail has large friction resistance and is not fast in moving speed due to sliding motion.

Disclosure of Invention

The invention aims to provide a V-shaped roller guide rail pair, which combines the advantages of a rolling linear guide rail and a V-shaped sliding guide rail and solves the problems that the existing rolling linear guide rail has poor vibration resistance and a sliding flat key is not suitable for high-speed movement.

The technical scheme of the invention is that the V-shaped roller guide rail pair is characterized by consisting of a V-shaped guide rail and a V-shaped roller sliding block; the middle part of the V-shaped guide rail is provided with a V-shaped groove, and the V-shaped roller slide block consists of a slide block body, two rows of circulating roller chains and a left end and right end return device; two rolling grooves are formed in two sides of the sliding block body, correspondingly, two through returning grooves are formed in the middle of the sliding block body, returning devices are installed at the left end and the right end of the sliding block body, and the two rows of circulating roller chains perform reciprocating circulating rolling through the rolling grooves in the sliding block body, the returning devices at the left end and the right end and the two through returning grooves in the middle of the sliding block body.

Furthermore, the rollers in the rolling grooves on the sliding block body are 0.5mm higher than the sliding block body when in work.

Further, when the V-shaped roller slide block rolls back and forth in the V-shaped groove on the V-shaped guide rail, the slide block body is not in contact with the V-shaped groove, and therefore the reciprocating circular rolling of the circular roller chain is achieved.

Furthermore, the left and right end reversers are fastened on the sliding block body through fastening screws.

The invention has the following beneficial effects:

1. the V-shaped roller guide rail pair can support and guide the moving component, and can do reciprocating linear movement along a given direction, and the circulating rollers are used between the V-shaped guide rail and the sliding block, so that high-precision linear movement is realized, and the V-shaped roller guide rail pair has a high-rigidity rolling function.

2. The invention combines the advantages of the rolling linear guide rail and the V-shaped sliding guide rail, has the characteristics of high rigidity, high precision, high speed and high vibration resistance, and is particularly suitable for automatic equipment with high speed and high vibration requirements.

Detailed Description

As shown in fig. 1 and 2, the V-shaped roller guide rail pair comprises a V-shaped guide rail 1 and a V-shaped roller slider 2, wherein a V-shaped groove is formed in the middle of the V-shaped guide rail 1, and the V-shaped roller slider 2 moves along the V-shaped groove.

As shown in fig. 3 and 4, the V-shaped roller slide block is composed of a slide block body 1, two rows of circulating roller chains 6, a right end reverser 4 and a left end reverser 7; two rolling grooves 8 are machined on two sides of the slider body 1, and the two rolling grooves are shown in figure 4. Correspondingly, two through return grooves 9 are formed in the middle of the slider body 1, a left end return device 7 and a right end return device 4 are respectively installed at the left end and the right end of the slider body 1, the left end return device and the right end return device are fastened on the slider body through fastening screws 3, the circulating roller chain 6 can perform reciprocating circulating rolling through the rolling grooves 8 in the slider body, the left end return device and the right end return device and the two through return grooves 9 in the middle of the slider body, rollers in the rolling grooves 8 in the slider body are 0.5mm higher than the slider body when working, when the V-shaped roller slider 2 rolls back and forth in the V-shaped grooves in the middle of the V-shaped guide rail 1, the slider body 1 is not in contact with the V-shaped grooves in the V-shaped guide rail, but the circulating roller chain 6 performs reciprocating circulating rolling along the two sides of the V-shaped grooves, high-precision linear motion is achieved, and the high-rigidity rolling function is achieved.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are intended to be covered by the scope of the present invention.
