Abstract

The invention discloses a rolling guide device. The rolling guide device comprises a guide box. Two guide rollers and a regulating mechanism are arranged in the guide box, wherein the two guide rollers are oppositely arranged and used for conveying rolled pieces, and the regulating mechanism is used for regulating the space between the two guide rollers. The two guide rollers are rotatably fixed to two eccentric shafts oppositely arranged respectively. The two eccentric shafts are installed on the guide box in a rotary mode. The regulating mechanism comprises two identical worm wheels, and the two worm wheels are arranged at the ends, extending out of the guide box, of the same sides of the two eccentric shafts. A worm is arranged between the two worm wheels and is meshed and connected with the two worm wheels on the outer sides of the worm respectively. According to the scheme, by means of the regulating mechanism formed by the worm and the worm wheels, synchronous rotating regulation on the two eccentric shafts of the fixed guide rollers is achieved, and then wide-range and high-precision space regulation between the two guide rollers can be achieved.

Description

A kind of rolling guide

Technical field

The present invention relates to rolled piece conveying equipment field, be specifically related to a kind of rolling guide.

Background technology

Rolling guide has the advantages such as friction is little, long service life, therefore in rolled piece is carried, is widely used.In order to make a set of guide and guard meet the guiding delivery requirements of sizes specification rolled piece, so on rolling guide, be provided with the governor motion that deflector roll is carried out to spacing adjusting.

Summary of the invention

The object of this invention is to provide a kind of rolling guide, and can realize deflector roll on a large scale, high-precision adjusting.

For achieving the above object, the present invention has adopted following technical scheme: a kind of rolling guide, it is characterized in that: comprise guide case body, in guide case body, be provided with two deflector rolls that positioned opposite carries rolled piece and the governor motion that the spacing between two deflector rolls is regulated, two deflector rolls rotate respectively and are fixed on two eccentric shafts that are oppositely arranged, two eccentric shafts are rotatably installed on guide case body, governor motion comprises that two eccentric shafts extend to the identical worm gear that the homonymy end of guide case body periphery arranges respectively, between two worm gears, be provided with a worm screw, worm screw is meshed and is connected with two worm gears in its outside respectively.

The governor motion consisting of worm and worm wheel in such scheme, realizes the synchronous rotation of two eccentric shafts of stationary guide roller is regulated, so realize to two deflector rolls on a large scale, high-precision spacing regulates.

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the B-B cutaway view of Fig. 1.

The specific embodiment

The object of the present invention is to provide and a kind ofly can carry out convenience to deflector roll spacing, regulate on a large scale, the rolling guide of carrying to adapt to the guiding of different size rolled piece, its scheme of taking is as Fig. 1, 2, shown in 3, a kind of rolling guide, comprise guide case body 10, in guide case body 10, be provided with two deflector rolls 11 that positioned opposite carries rolled piece and the governor motion that the spacing between two deflector rolls 11 is regulated, two deflector rolls 11 rotate respectively and are fixed on two eccentric shafts 14 that are oppositely arranged, two eccentric shafts 14 are rotatably installed on guide case body 10, governor motion comprises that two eccentric shafts 14 extend to the identical worm gear 12 that the homonymy end of guide case body 10 peripheries arranges respectively, between two worm gears 12, be provided with a worm screw 13, worm screw 13 is meshed and is connected with two worm gears 12 in its outside respectively.Described worm gear 12 and worm screw 13 are separately positioned on the bottom of guide case body 10.The governor motion consisting of worm screw 13 and worm gear 12 in such scheme, realizes the synchronous rotation of two eccentric shafts 14 of stationary guide roller 11 is regulated, so realize to two deflector rolls on a large scale, high-precision spacing regulates.

Further scheme is, the bottom of guide case body 10 is provided with a base plate 15, worm gear 12 and worm screw 13 are arranged between guide case body 10 and base plate 15, deflector roll 11 is less than the height that the area of absence of holding deflector roll 11 is set on guide case body 10 along its axial height, in the both ends of the surface of worm gear 12, the axis around worm gear 12 offers annular slot respectively, in annular slot, be arranged with the air ring 121 that protrudes from worm gear 12 end faces, the air ring 121 arranging in worm gear 12 both ends of the surface leans with the bottom surface of guide case body 10 and the upper face of base plate 15 respectively, air ring 121 is synchronizeed rotation with worm gear 12.Two deflector roll 11 stage casings along roll body circumferentially respectively correspondence be provided with annular groove.Air ring 121 leans with bottom surface and the base plate 15 of guide case body 10, be mainly used for the fine setting of the installation on the assembly line location to deflector roll 11, by regulating the thickness of each air ring 121, the height in guide case body 10 to deflector roll 11 is finely tuned, so that the position at deflector roll 11 places is consistent with default pipeline, after long-term use, air ring 121 can be frayed, therefore by removing being fastened on the air ring 121 wearing and tearing in annular slot, the air ring 121 more renewing, avoids changing whole guiding mechanism.In addition, described eccentric shaft 14 comprises that both ends axis is positioned at collinear construction section and middle part for the eccentric segment of deflector roll 11 is installed, the installing hole of described worm gear 12 is a stepped hole being constituted by first and second vestibule section, the installation that matches with the first vestibule section of the construction section of eccentric shaft 14, the installation that matches with the second vestibule section of the eccentric segment of eccentric shaft 14.

In a word, rolling guide provided by the invention, its can be effectively to two deflector roll 11 spacing carry out conveniently, on a large scale, high-precision adjusting, to adapt to the guiding of different size rolled piece, carry.
