Description

The elongated feed mechanism

The utility model relates to a kind of structure of automatic feeding, particularly relates to the elongated feed mechanism that a kind of feeding is smooth and easy, stability is high.

General existing metal sawing machinery (circular sawing machine, band sawing machine etc.), when handling large-scale workpiece, in order to save manpower, mostly utilize the automatic feeding mode, workpiece is passed to Working position, for example: the feed mechanism of sawing machinery is longitudinally to be provided with two guide rails on board, one feeding body is set on this two guide rail, when being subjected to oil pressure actuated, can move along vertical generation of board, be provided with a feeding clamp seat and stride on the feeding body, this feeding clamp seat end face is provided with a plier groups, can be with the work-holding location of desire cutting, when the feeding body when the sawing locality moves, utilize plier groups one end clamping of workpiece can be moved and level off to Working position, and utilize a stationary clamp pincers tightening position that is arranged on the Working position place, the plier groups of this feeding clamp seat end face can discharge workpiece, and this feeding body, feeding clamp seat will be reversed driving and return the home position, and prepares the clamping of charging next time.

Though above-mentioned elongated feed mechanism can reach the automatic feeding purpose, but because after the manufacturing of elongated workpiece finishes, the center-point at each position is symmetry fully, so the major axis of elongated workpiece might not be linearly, and in being subjected to the plier groups hitch feed, workpiece can produce the mating component of feed mechanism and push, oppresses, and after after a while, the precision between each member of feed mechanism will be affected.

In order to address the above problem, moral, day etc., state developed a kind of floating structure, feeding clamp seat is designed to and can produces sway with respect to the feeding body, and can automatically reply original position again behind the release workpiece, to improve the shortcoming that the workpiece centre point departs from, still, this floating structure is provided in a side of a wherein side of feeding body and feeding clamp seat, stability when feeding clamp seat produces horizontal sway with respect to the feeding body is not good, can have influence on the smooth and easy of feeding.

The purpose of this utility model is to provide a kind of elongated feed mechanism, when work center line has the situation of departing from and when carrying out feeding, but feeding clamp seat automatic compensation and floating about producing with respect to the feeding body to keep the stability of preferable feeding, reaches feeding purpose smoothly.

Elongated feed mechanism of the present utility model, comprise a feeding body, four floating installations and a feeding clamp seat, this feeding body can be done longitudinal sliding motion along the board of sawing machinery, respectively be provided with two post holes in two sides, this floating installation is by a guide rod, compression spring and one slide bearing and form, this guide rod one end is sheathed to be fixed in the post hole of these feeding body two sides, the other end is straight extending outwards, and with this compression spring, sliding bearing is set on this guide rod in regular turn, and these both sides, feeding clamp seat bottom surface respectively are provided with a protruding seat, between this two protruding seat, form a depressed part, the width of this depressed part is greater than the width between the feeding body two sides, and when the depressed part of this feeding clamp seat overlaps fashionable from this feeding body end face, respectively be formed with a gap between these feeding body two sides and the protruding seat with proper width, and this protruding seat is with respect to the position that is provided with of this guide rod, respectively be provided with two axis holes along horizontally set, this side face packing of sliding bearing is fixed on this axis hole inner ring surface, therefore, when the workpiece centre point departs from and be subjected to this feeding clamp seat clamping, this feeding clamp seat can be by the cooperation of this gap and floating installation and automatic compensation, and with respect to floating about this feeding body generation, to keep the stability of preferable feeding, reach feeding purpose smoothly.
