Abstract
The utility model provides a stepping feeding structure, which is simple in structure, low in manufacturing cost, and applicable to simple multi-station step-by-step propulsion mechanisms. The stepping feeding structure comprises a cylinder and stepping racks, wherein the stepping racks are arranged on the two sides of the feeding structure; and the stepping feeding structure is characterized in that the tooth surfaces of the stepping racks arranged on the two sides of the feeding structure are opposite to each other, the tooth profiles of the stepping racks are closed up towards the stepping direction, a dragging block and a moving block are respectively arranged between the tooth surfaces of the stepping racks, installing blocks on both sides of the dragging block and the moving block are respectively adhered to the tooth profiles of the stepping racks, the installing blocks on the two sides of the dragging block and the moving block are connected by a spring, the moving block is arranged at the front part of the stepping direction relative to the dragging block, a tension sprig is arranged between the moving block and the dragging block, the cylinder is fixedly arranged on the moving block, and a cylinder arm of the cylinder is fastened on the dragging block.
Description
Technical field
The utility model relates to the technical field of mass transport structure, is specially a kind of feeding structure of stepping.
Background technology
The stepping feeding structure of existing material conveying mechanism, it is all controlled through stepping motor, and for the mechanism that simple a plurality of stations progressively advance, its manufacturing cost is higher.
Summary of the invention
To the problems referred to above, the utility model provides a kind of feeding structure of stepping, and its simple in structure, low cost of manufacture is applicable to the mechanism that simple a plurality of station progressively advances.
A kind of feeding structure of stepping; Its technical scheme is such: it comprises the stepping tooth bar of cylinder, both sides; It is characterized in that: the flank of tooth of the said stepping tooth bar of both sides in opposite directions, the profile of tooth of said stepping tooth bar closes up towards step direction, is equipped with respectively between the flank of tooth of the said stepping tooth bar of both sides and drags piece, the piece of advancing; The profile of tooth of saidly drag piece, the both sides mounting blocks of the piece of advancing being fitted said stepping tooth bar respectively; Connect through spring between the said mounting blocks of both sides, the said piece of advancing drags the front portion that piece is positioned at step direction with respect to said, the said piece of advancing, drags extension spring is installed between the piece; Cylinder is fastening to be installed on the said piece of advancing, and the cylinder arm of said cylinder is anchored on the said piece that drags.
After adopting the structure of the utility model; For the mechanism that simple a plurality of stations progressively advance, during the elongation of the cylinder arm of cylinder, because the profile of tooth of stepping tooth bar closes up towards step direction; The profile of tooth of drag piece, the both sides mounting blocks of the piece of advancing being fitted the stepping tooth bar respectively; Advance piece and be positioned at the front portion of step direction with respect to dragging piece, dragging piece can't move to reverse step direction to overcoming the profile of tooth limitation ot it, so cylinder arm makes the both sides mounting blocks compression of piece and smoothly to the step direction lattice that move of advancing to the antagonistic force of extension spring; When the cylinder arm of cylinder shrinks; The piece of advancing can't move to reverse step direction to overcoming the profile of tooth limitation ot it, so cylinder arm makes the both sides mounting blocks compression that drags piece and smoothly to the step direction lattice that move to the antagonistic force of extension spring, thereby accomplishes stepping smoothly; Its simple in structure, low cost of manufacture is applicable to the mechanism that simple a plurality of station progressively advances.
Description of drawings
Fig. 1 is the front view structural representation of the utility model.
The specific embodiment
See Fig. 1, it comprises the stepping tooth bar 2 of cylinder 1, both sides, and the flank of tooth of the stepping tooth bar 2 of both sides in opposite directions; The profile of tooth of stepping tooth bar 2 closes up towards step direction; Be equipped with respectively between the flank of tooth of the stepping tooth bar 2 of both sides and drag piece 3, the piece 4 of advancing, the profile of tooth of drag piece 3, the both sides mounting blocks 5 of the piece 4 of advancing being fitted stepping tooth bar 2 respectively connects through spring 6 between the mounting blocks 5 of both sides; Advance piece 4 and be positioned at the front portion of step direction with respect to dragging piece 3; Advance piece 4, drag extension spring 7 be installed between the piece 3, the cylinder 1 fastening piece 4 of advancing that is installed on, the cylinder arm of cylinder 1 is anchored on and drags piece 3.
