Description

A kind of pay-off of movable block

Technical field

The utility model relates to the technical field of material conveying structure, is specially a kind of pay-off of movable block.

Background technology

The existing feeding structure with movable block, it drives movable block to complete feeding by straight line cylinder, in straight line cylinder operational process, its stroke needs strict control, need to someone operate specially, and its operation is wasted time and energy, and often make mistakes, You Liao road can be leaked and send.

Summary of the invention

For the problems referred to above, the utility model provides a kind of pay-off of movable block, and it makes the accuracy rate of movement of movable block high, guarantees that each material road all delivers to material, and operate time saving and energy saving.

A kind of pay-off of movable block, its technical scheme is such: it comprises movable block, line slideway, be evenly equipped with the arrangement board in material road, described movable block bottom is installed in the guide-track groove of described line slideway, the first two ends of described movable block have material receiving port towards the position in described material road, the rear end, position of the corresponding described material receiving port of described movable block is separately installed with cylinder, it is characterized in that: described movable block bottom welding has nut, stepping motor is supported on base plate, the mouth of described stepping motor is connected with screw mandrel, described screw mandrel passes through the bearing horizontal arrangement at two ends in the below of described line slideway, described bearing is supported on described base plate, described screw mandrel runs through described nut, and be connected with nut thread.

Adopt after structure of the present utility model, stepping motor drives screw mandrel to rotate, drive nut straight-line feed, and then drive movable block straight-line feed, because the miles of relative movement turning around of stepping motor is constant, only need to mate suitable distance to stepping motor, the spacing distance that can guarantee the each mobile distance He Liao road of movable block is consistent, it makes the accuracy rate of movement of movable block high, guarantees that each material road all delivers to material, and operate time saving and energy saving.
