Abstract

The utility model discloses a rolling guide with adjustable roller spacing. The rolling guide comprises a guide body, a left guide roller supporting arm and a right guide roller supporting arm. Adjusting mechanisms used for adjusting the spacing between two guide rollers are further arranged at the front ends of the two guide roller supporting arms. Each adjusting mechanism comprises a wedge-shaped block which is placed between the two guide roller supporting arms and is in an inverted cone shape, and an adjusting assembly which is used for adjusting the wedge-shaped block to move in the vertical direction. Movable push rods which are arranged in the horizontal direction are arranged between the wedge face on the left side and the wedge face on the right side of the wedge-shaped blocks and the left guide roller supporting arms and between the wedge face on the left side and the wedge face on the right side of the wedge-shaped blocks and the right guide roller supporting arms. The adjusting assemblies adjust the wedge-shaped blocks to move downwards to push the movable push rods to operate towards the outer side to abut against the front end of the left guide roller supporting arm and the front end of the right guide roller supporting arm to expand around a hinged shaft. According to the technical scheme, the wedge-shaped blocks which move in the vertical direction, the movable push rods which are arranged in the horizontal direction and the adjusting assemblies together form the adjusting mechanism, when the adjusting assemblies adjust the wedge-shaped blocks to move in the vertical direction, the wedge-shaped blocks can abut against the movable push rods to horizontally move towards the outer side to abut against the rear ends of the guide roller supporting arms, and therefore the spacing between the two guide rollers is adjusted to be small.

Description

Roller interval adjustable rolling guide

Technical field

The utility model relates to rolled piece conveying equipment field, is specifically related to a kind of roller interval adjustable 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 same pipeline meet the guiding delivery requirements of sizes specification rolled piece, therefore on rolling guide, be conventionally provided with the governor motion that deflector roll is carried out to spacing adjusting, on rolling guide, distance regulating mechanism used is mostly worm and gear governor motion at present, not only complex structure of worm and gear governor motion, processing cost is high, and degree of regulation is low, the scope of adjusting is little.

Summary of the invention

The purpose of this utility model is to provide a kind of roller interval adjustable rolling guide, and can realize deflector roll on a large scale, high-precision adjusting.

For achieving the above object, the utility model has adopted following technical scheme: a kind of roller interval adjustable rolling guide, comprise guide and guard body, in guide and guard body, be provided with the passage passing through for rolled piece, the discharging opening place of passage is provided with the deflector roll of two positioned opposite, a left side for guide and guard body, right both sides arrange respectively a left side, right guide rolls support arm, two deflector rolls rotate respectively and are fixed on a left side, the rear end of right guide rolls support arm, the middle part of two guide rolls support arms is articulated and connected with guide and guard body respectively and to form this jointed shaft being articulated and connected axial, axially all arranging along vertical of deflector roll, the front end of two guide rolls support arms is connected by an extension spring, it is characterized in that: two guide rolls support arm front ends are also provided with the governor motion that regulates spacing between two deflector rolls, governor motion comprises that one is the wedge of inverted cone shape and the adjusting part that regulates wedge to move along vertical between two guide rolls support arms, a wedge left side, the wedge surface of right both sides is with left, the movable push bar that along continuous straight runs is arranged is set respectively between right guide rolls support arm, adjusting part regulates the descending promotion movable push bar of wedge to move laterally and supports a left side, the front end of right guide rolls support arm extends out around jointed shaft.

The wedge moving along vertical in such scheme, movable push bar, the adjusting part that along continuous straight runs is arranged form governor motion jointly, when adjusting part regulates wedge to move along vertical, wedge can push movable push bar translation laterally and support deflector roll hold-down arm rear end, thereby the spacing of two deflector rolls is turned down.It is high that the governor motion of above-mentioned formation can be realized the precision that the large spacing range between two deflector rolls regulates and regulate.
