Abstract
The utility model relates to a hole-pitch adjusting mechanism for a leather punching machine, which comprises jumper bar supports which are parallelly arranged, a jumper bar is movably arranged in each jumper bar support, the jumper bar is externally sleeved with a spring, a concave platform of each jumper bar support is provided with a lower die, a base is provided with an expansion bracket, a regulating block is arranged in the expansion bracket and is matched with an adjusting screw, and guide pins on the expansion bracket are inserted into guide grooves on the bottoms of the jumper bar supports. The utility model overcomes the defect of lacking the effective design of hole-pitch adjustment of the leather punching machine in the prior art; with the design, hole pitches of the punching machine can be adjusted by rotating the adjusting screw to extend the expansion bracket; the hole pitches are almost completely consistent, and the operation and the control are convenient; and the hole-pitch adjusting mechanism for the leather punching machine has the advantages of compact structure, quick and orderly punching, convenient adjustment of the hole pitches, and strong reliability.
Description
Affiliated technical field
The utility model relates to a kind of leather punching pitch-row guiding mechanism.
Background technology
In traditional footwear leather machinery, there is not special automatic leather punching design, the drilling process in the footwear nation manufacture craft is finished by craft fully, inefficiency not only, and the interval of pitch-row also is difficult to accomplish in full accord, is unfavorable for the processing of subsequent processing, also causes the instability of product quality.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of leather punching pitch-row guiding mechanism, the compact conformation of this leather punching pitch-row guiding mechanism, and punching is neat rapidly, easy to adjust, the good reliability of pitch-row.
The technical scheme that its technical problem that solves the utility model adopts is: comprise the jumper bar bearing that is arranged in parallel, the movable jumper bar of installing in each jumper bar bearing, the jumper bar outer casing spring, on the concave station of jumper bar bearing counterdie is set, expansion bracket is set on base, be provided with regulating block in the expansion bracket, regulating block matches with adjusting screw(rod), and the pilot pin on the expansion bracket inserts in the guide groove of jumper bar rest base.
Expansion bracket is hinged to constitute by many groups of upper and lower braces and draws in the net structure, and the center hinge of its bottom one end is positioned on the base.
Relative upper and lower brace center is hinged, and adjacent upper and lower brace end is hinged, the outstanding pilot pin that forms of jointed shaft that the end is hinged.
The two ends of jumper bar bearing form protruding rafter, and protruding rafter sleeve is in the groove at base two ends.
Groove is formed by base and " L " shape pressing plate cooperation that is fixed on the base two ends.
The utility model only needs to rotate adjusting screw(rod) by above-mentioned specific design, the flexible pitch-row that can regulate puncher of expansion bracket, and each pitch-row is almost completely consistent, control very conveniently, have compact conformation, punching is neat rapidly, pitch-row is easy to adjust, the advantage of good reliability.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an assembled construction schematic diagram between expansion bracket and jumper bar bearing.
The specific embodiment
As shown in the figure, the utility model comprises the jumper bar bearing 1 that is arranged in parallel, the movable jumper bar 2 of installing in each jumper bar bearing 1, jumper bar 2 outer casing springs 14, on the concave station 15 of jumper bar bearing counterdie 17 is set, expansion bracket 4 is set on base 3, be provided with regulating block 5 in the expansion bracket 4, regulating block 5 matches with adjusting screw(rod) 6, and the pilot pin 7 on the expansion bracket 4 inserts in the guide groove 8 of jumper bar bearing 1 bottom.Expansion bracket 4 is hinged to constitute by many groups of upper and lower braces 9,10 and draws in the net structure, and the center hinge 11 of its bottom one end is positioned on the base 3.Relative upper and lower brace 9,10 centers are hinged, and adjacent upper and lower brace 9,10 ends are hinged, the outstanding pilot pin 7 that forms of jointed shaft that the end is hinged.The two ends of jumper bar bearing 1 form protruding rafter 16, and protruding rafter 16 sleeves are in the groove 12 at base 3 two ends.Groove 12 is formed by base 3 and " L " shape pressing plate 13 cooperations that are fixed on base 3 two ends.When dashing for 2 times to cooperate with counterdie 16, jumper bar can on leather, get the hole in working order down.When needing to adjust pitch-row, rotate adjusting screw(rod) 6, adjusting screw(rod) 6 makes regulating block 5 parallel moving, and the brace that regulating block 5 pullings link to each other makes expansion bracket 4 flexible, and the pilot pin 7 on the expansion bracket 4 also makes each jumper bar bearing 1 relatively move, thereby reaches the purpose of adjusting pitch-row.
