Abstract
The utility model relates to an automatic chaining machine, in particular to a feeding and pressing mechanism for the automobile chaining machine. The feeding and pressing mechanism aims at solving the technical problems that when the diameter of a chain ring of a chain is greater, the condition of returning the materials occurs and the like due to the fact that an acting force of an air cylinder of the existing chaining machine cannot enable materials to be clamped by a clamping claw because of a great pull force of a charging tray applied on the materials in the prior art. The feeding and pressing mechanism comprises an air cylinder fixing seat, wherein an air cylinder is fixedly arranged on the air cylinder fixing seat through an air cylinder seat; a connecting plate is connected to an ejector rod of the air cylinder; a groove is formed in the connecting plate; an upper hinge and a lower hinge are respectively hinged into the groove; the other end of the upper hinge is hinged onto the fixing seat; the other end of the lower hinge is hinged onto a swing block; the swing block is connected with the fixing seat; an inverted U-shaped groove is formed in the lower part of the swing block; an upper clamping claw is arranged in the inverted U-shaped groove and is pressed by an upper pressing block; an inverted U-shaped groove is also formed in the lower part of the fixing seat; and a lower clamping claw is arranged in the inverted U-shaped groove and is pressed by a lower pressing block.
Description
Technical field
The utility model relates to a kind of automatic chain braider, especially relates to a kind of automatic chain braider feeding hold-down mechanism.
Background technology
Chain is made of some beckets all linked with one another, and these beckets are formed through cutting, bending, shaping by the wire rod of strip.Traditional chaining equipment has (1) punch press that chaining mould (dash and compile) is installed, and the impression of locating is in various degree had relatively high expectations to the operative employee, and security risk is bigger.(2) have a kind of vertical chain braider should not work out the mould heart to the relatively poor pitch chain of various chain link adaptability and fracture easily, (3) have its complex structure of volume for sleeping in of a kind of imitative external product, and the high maintenance cost of equipment cost is big.Chinese patent discloses a kind of chain braider (Granted publication number: CN1895812), it mainly comprises: frame, Poewr transmission mechanism, shearing depression bar by the Poewr transmission mechanism driving, slide unit, be connected in and break the hook jumper bar on the slide unit, the pressure ring jumper bar, chain cable turns to let-off gear(stand), matches to be arranged on bending slot die on the frame correspondence position, the pressure ring channel mould, the pressure ring drift is by rail, crotch slideway between bending slot die through hole below and pressure ring channel mould, be displaced to folder hook pincers the pressure ring channel mould from slideway exit drag hook, drive the folder hook clamp reciprocating transmission mechanism and intermittently the tractive chain cable draw-off mechanism and be configured in cutting mechanism before wire rod straightening conveying mechanism; Also be provided with domain top die on the slide unit, the corresponding position is provided with the domain dip mold of coupling on the frame; Poewr transmission mechanism comprises the wheel shaft and the flywheel, drive, cam and the connector that are set on the axle on the top of being located at fuselage; The pressure ring jumper bar is by the ring jumper bar on stamping arm, be slidingly connected to vertical with stamping arm, is sleeved on the return spring of ring on the jumper bar and is constituted, and this ring jumper bar is provided with roller with this end that contacts by rail; Chain cable turn to let-off gear(stand) be by have cross hollow endoporus, guiding tube pass travelling gear that the slide unit platen termination outside connecting, be meshed with travelling gear be articulated in the fan tooth piece on the slide unit deckle board and drive that fan tooth piece comes the fork of back rotation and the chain cable fairlead be located at above the guiding tube is constituted.But when the chain ring diameter of chain was big, because charging tray is very big to the pulling force of material, the active force of chain braider cylinder possibly can't make jaw that feed collet is tight at present, thereby can cause the generation of the material returned.
The utility model content
The utility model provides a kind of automatic chain braider feeding hold-down mechanism, it mainly is to solve existing in prior technology when the chain ring diameter of chain greatly the time, because charging tray is very big to the pulling force of material, at present the active force of chain braider cylinder possibly can't make jaw that feed collet is tight, thereby can cause the technical problem of the generation etc. of the material returned.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Automatic chain braider feeding hold-down mechanism of the present utility model, comprise the cylinder holder, described cylinder holder fixedly has cylinder by cylinder block, the push rod of cylinder is connected with connecting plate, slot on the connecting plate, be hinged with upper hinge, following hinge in the groove respectively, the upper hinge other end is hinged on the holder, and the following hinge other end is hinged on the centering block, and centering block is connected with holder, the centering block bottom has the inverted U groove, upper gripper jaw is housed in the groove, and compresses by upper holder block, the bottom of holder also is provided with the inverted U groove, jaw is housed down in the groove, and compresses by lower lock block.Centering block can be installed in the middle part of holder, adopts bearing pin to connect, and centering block can rotate around bearing pin.The upper end of centering block has a groove, and following hinge end section namely embeds wherein, connects by bearing pin.Like this, after the push rod of cylinder moved forward, following hinge can promote the centering block rotation, thereby jaw is finished the action that clamps material up and down.
As preferably, the bottom of described inverted U groove is provided with screwed hole, and the adjustment screw is housed in the screwed hole.By adjusting screw, can regulate the length of upper gripper jaw or following jaw.
As preferably, described cylinder holder is connected by bearing pin with cylinder block, and the push rod of cylinder is by the connecting plate that is threaded.It is comparatively convenient to connect like this.
Therefore, the utility model adds linkage at the cylinder place, makes chain braider only need a very little power large diameter chain link can be clamped when feeding, and is more laborsaving, simple and reasonable for structure.
