Abstract
The invention relates to a leather drilling mechanism, which comprises jumper bar supports which are arranged in parallel, wherein a jumper bar is movably arranged in each jumper bar support, a spring is sleeved on the outer side of the jumper bar, a counter die is arranged on a concave platform of the jumper bar support, an expansion bracket is arranged on a chassis, a regulating block is arranged in the extension bracket, the regulating block is matched with a regulating bolt, a guide pin in the extension bracket is inserted in a guide slot on the bottom of the jumper bar support, regulating holes are respectively opened on each jumper bar support, centrifugal wheels which are matched thereof are arranged in the regulating holes, and each centrifugal wheel is connected with a centrifugal wheel shaft. The drilling mechanism overcomes the weaknesses of lacking effective leather drilling machines and relative hole distance and hole site regulating designs in the prior art, only the regulating bolt and the centrifugal wheels are rotated, can the hole distance and the hole site of drilling machines be regulated through the above design, and each hole distance all most the same, and the operation is extremely convenient. The drilling mechanism) has the advantages of compact structure, fast and neat drilling, convenient hole distance and hole site regulation and strong reliability.
Description
Affiliated technical field
The present invention relates to a kind of leather punching mechanism.
Background technology
In traditional footwear leather machinery, there is not special automatic leather punching design, drilling process in the footwear nation manufacture craft is finished by craft fully, inefficiency, and the interval of pitch-row, position, hole arrange also be difficult to accomplish in full accord, particularly when the position, hole in each hole is arranged as a curve, just more be difficult to control, not only strengthened the difficulty that subsequent processing is handled, also cause the instability of quality product.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the invention provides a kind of leather punching mechanism, the compact construction of this leather punching mechanism, punching is neat rapidly, pitch-row, easy to adjust, the good reliability in position, hole.
The technical solution adopted for the present invention to solve the technical problems 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), pilot pin on the expansion bracket inserts in the guide groove of jumper bar rest base, in each jumper bar bearing, all offer and adjust the hole, adjust the eccentric wheel that assembling matches with it in the hole, each eccentric wheel is linked to each other by camshaft.
Expansion bracket is hinged to constitute by many groups of upper and lower connection pieces and draws in the net structure, and the center hinge of its bottom one end is positioned on the base.
Relative upper and lower connection piece center is hinged, and adjacent upper and lower connection piece 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.
Camshaft is positioned on the axle bracket, and axle bracket is fixed on the base, and eccentric both sides are provided with catch.
The present invention only needs to rotate adjusting screw(rod) and camshaft by above-mentioned specific design, can regulate the pitch-row and the position, hole of tapping and plugging machine, and each pitch-row is almost completely consistent, controls very conveniently, has compact construction, punching is rapidly neat, and pitch-row, position, hole are easy to adjust, the advantage of good reliability.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present invention is described.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an assembled construction synoptic diagram between expansion bracket and jumper bar bearing.
Embodiment
As shown in the figure, the present invention includes 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 3, on the concave station 4 of jumper bar bearing 1 counterdie 5 is set, expansion bracket 7 is set on base 6, be provided with regulating block 8 in the expansion bracket 7, regulating block 8 matches with adjusting screw(rod) 9, pilot pin 10 on the expansion bracket 7 inserts in the guide groove 11 of jumper bar bearing 1 bottom, all offer in each jumper bar bearing 1 and adjust hole 12, adjust the eccentric wheel 13 that assembling matches with it in the hole 12, each eccentric wheel 13 is linked to each other by camshaft 14.Expansion bracket 7 is hinged to constitute by many groups of upper and lower connection pieces 15,16 and draws in the net structure, and the center hinge 17 of its bottom one end is positioned on the base 6.Relative upper and lower connection piece 15,16 centers are hinged, and adjacent upper and lower connection piece 15,16 ends are hinged, the outstanding pilot pin 10 that forms of jointed shaft that the end is hinged.The two ends of jumper bar bearing 1 form protruding rafter 22, and protruding rafter 22 sleeves are in the groove 18 at base 3 two ends, and groove 18 is formed by base 6 and " L " shape pressing plate 19 cooperations that are fixed on base 6 two ends.Camshaft 14 is positioned on the axle bracket 20, and axle bracket 20 is fixed on the base 6, and the both sides of eccentric wheel 13 are provided with catch 21.Catch 21 can make the work of each eccentric wheel 13 not disturb mutually.When dashing for 2 times to cooperate with counterdie 5, jumper bar can on leather, get hole, 3 reset responses of spring in working order down.When needing to adjust pitch-row, rotate adjusting screw(rod) 9, adjusting screw(rod) 9 makes regulating block 8 parallel moving, and the connection piece that regulating block 8 pullings link to each other makes expansion bracket 7 flexible, and the pilot pin 10 on the expansion bracket 7 also makes each jumper bar bearing 1 relatively move, thereby reaches the purpose of adjusting pitch-row.When needing to adjust the position, hole, rotate camshaft 14, make the also rotation simultaneously of each eccentric wheel 13, because each eccentric wheel 13 is to be installed in the adjustment hole of offering in the jumper bar bearing 1 12, and eccentric angle difference, therefore eccentric wheel 13 promotes each jumper bar bearing 1 and makes it to produce the parallel of different distance to move, thereby reaches the purpose of adjusting the position, hole.
