Description

A kind of rivet inserter materials clamp mechanism

Technical field

The utility model relates to the feed collet mechanism that uses on a kind of rivet inserter.

Background technology

It is a kind of fixedly connected mode that is in daily use that rivet is connected in the machining, adopts manual mode that rivet is placed into usually and carries out the punching press riveted joint behind the precalculated position.This mode has increased operative employee's labour intensity on the one hand, has reduced operating efficiency, and also there is very big hidden danger in the safety operation aspect.At present, some automatic riveters have appearred on the market, but in fact still manually-operated of this class rivet driver usually, after being the position of artificial quilting rivet, after manual activation such automatic riveter self-feeding and finish rivet " blooming " action, it is not the full-automatic rivet driver of unattended formula, though wherein some rivet driver has been realized full automatic function, but its positioning accuracy is not high, the rate that manufactures a finished product is low, this wherein most important reason be that the feed collet mechanism of rivet driver improves inadequately and causes, the plug-in unit efficient of feed collet mechanism also can directly have influence on production efficiency of products, goes back the fairly perfect clamp device of neither one in the market.

The utility model content

The technical problems to be solved in the utility model provides the feed collet mechanism that uses on the high rivet inserter of a kind of accurate positioning, plug-in unit efficient.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of rivet inserter materials clamp mechanism, comprise vertical pedestal and be fixedly mounted on inserted link cover on this pedestal, be movably installed with form of a stroke or a combination of strokes plug-in unit main shaft in the inserted link cover, installation is connected with the feeding guide that an end upwarps in the pedestal lower end, described plug-in unit main shaft bottom has spacing hole, the limit shaft of regulating the plug-in unit travel of spindle is housed in this spacing hole, and plug-in unit main shaft lower end internal activity is equipped with pilot pin; In the lower end of pedestal the spill holder is installed, is movably installed with two L shaped cursor slides by pin in the groove of this holder, L shaped feed collet all is equipped with in the lower end of two cursor slides, and each feed collet correspondence is loaded on the step surface of the step-like material folding piece that is fixed on the pedestal lower end.Be equipped with hanging column on the described material folding piece, install between hanging column and be connected with the spring that makes the material folding block reset.

The plug-in unit main shaft top that the inserted link cover is passed in described activity is provided with the anti-rotation hole, and inserted link is arranged with the alignment pin that the plug-in unit main shaft can not rotated in the inserted link cover, and this alignment pin extends in the anti-rotation hole, and inserted link puts end face upper edge longitudinal direction the screw that tightens up alignment pin is housed.

Have the hole on the described L shaped cursor slide, by the activity of pulley pin pulley is housed in this hole, adjustment screw of regulating the cursor slide stroke and the screw that is used for fixing this adjustment screw also are housed on the cursor slide.

Described spill holder is equiped with the gland that is complementary, and this gland is provided with set screw.

The utility model is by to the improvement of feed collet mechanism, make the rivet location more accurately, plug-in unit efficient is higher, thereby improved the operating efficiency of rivet inserter to a great extent.

Description of drawings

Accompanying drawing 1 is the utility model decomposing state structural representation; Accompanying drawing 2 is the utility model part decomposing schematic representation; Accompanying drawing 3 is the utility model assembling back structural representation.

The specific embodiment

For the ease of those skilled in the art's understanding, the utility model is further described below in conjunction with embodiment and accompanying drawing.

Shown in accompanying

drawing

1,2,3, a kind of rivet inserter materials clamp mechanism, comprise vertical pedestal 1, inserted link cover 2 is installed on this vertical pedestal 1, be movably installed with form of a stroke or a combination of strokes plug-in unit main shaft 3 in the inserted link cover 2, at the feeding guide 4 that pedestal 1 lower end attaching has an end to upwarp, plug-in unit main shaft 3 bottoms have spacing hole, the limit shaft 5 of regulating plug-in unit main shaft 3 strokes is housed in this spacing hole, and plug-in unit main shaft 3 lower end internal activities are equipped with pilot pin; In the lower end of pedestal 1 spill holder 6 is housed, be movably installed with two L shaped cursor slides 8 by pin 7 in the groove of this holder 6, L shaped feed collet 9 all is equipped with in the lower end of two cursor slides 8, each feed collet 9 correspondence is loaded on the step surface of the step-like material folding piece 10 that is fixed on pedestal 1 lower end, be equipped with hanging column 17 on the

material folding piece

10,17 installations of hanging column are connected with the spring 18 that makes the material folding block reset.Plug-in unit main shaft 3 tops offer the anti-rotation hole, and inserted link overlaps 2 tops and is provided with and makes plug-in unit main shaft 3 can not overlap in 2 the alignment pin 11 that rotates at inserted link, and this alignment pin 11 extends in the anti-rotation hole, and inserted link overlaps and longitudinally is provided with the screw 12 that tightens up this alignment pin 11 on 2 upper surfaces.Have the hole on the L shaped cursor slide 8, by pulley pin 13 pulley 14 is housed in this hole, adjustment screw 15 of regulating cursor slide 8 strokes and the screw 16 that is used for fixing this adjustment screw 15 also are housed on the cursor slide 8, and spill holder 6 is equiped with the gland 19 that is complementary, and this gland is provided with set screw 20.
