Detailed description of the invention
The following stated is only preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, is shown in shown in Fig. 1 and Fig. 2: Automatic continuous rotating punching machine, comprises frame 10 and up and down reciprocatingly device 23, and this up and down reciprocatingly device 23 is connected with red needle 30.Certainly, red needle 30 can be directly fixed on up and down reciprocatingly on device 23.Wherein, frame 10 is provided with pivot joint frame 13, is articulated with rotary punching apparatus 20 in pivot joint frame 13.This rotary punching apparatus 20 comprises fixture 21, and fixture 21 is connected with ratchet 22.Meanwhile, frame 10 is fixed with locating piece 221, up and down reciprocatingly device 23 is provided with driving lever 231, and this locating piece 221 and driving lever 231 all match with ratchet 22.So-called locating piece 221 matches with ratchet 22, refers to locating piece 221 and can withstand on the hook tooth of ratchet 22, thus makes ratchet 22 only can single direction rotation, such as only can turn clockwise.Certainly, locating piece 221 is connected with holddown spring 2211, and under the effect of this holddown spring 2211, locating piece 221 can hold out against the hook tooth of ratchet 22.So-called driving lever 231 matches with ratchet 22, refers to driving lever 231 under the drive of up and down reciprocatingly device 23, to top offset, thus stirs the hook tooth of ratchet 22, ratchet 22 is rotated.Such as, turn clockwise.Certainly, this driving lever 231 is connected to up and down reciprocatingly device 23 by unidirectional stopping means, thus when avoiding driving lever 231 to bottom offset, is subject to the stop of ratchet 22.
Shown in composition graphs 3 and Fig. 4, the fixture 21 for holding workpiece comprises conical pipe 211, is interspersed with clamping pipe 212 in conical pipe 211.Wherein, clamping pipe 212 is connected with front and back reciprocating apparatus 213, and meanwhile, the outside, one end of this clamping pipe 212 is for taper and this end is provided with card tooth 2121.The formation of card tooth 2121 can take the end clamping pipe 212 to have the mode of some clearance grooves.Like this, clamping pipe 212 is under the pulling of front and back reciprocating apparatus 213, and card tooth 2121 place, front end is to conical pipe 211 internal displacement, thus when workpiece is positioned in clamping pipe 212, workpiece is clamped by card tooth 2121.Front and back reciprocating apparatus 213 can take multiple common mode.Optimize, before and after this, reciprocating apparatus 213 comprises oil cylinder, is provided with piston 2122 in oil cylinder, and this piston 2122 connects clamping pipe 212.That is, piston 2122 is movable in the cylinder body of oil cylinder, and then drives clamping pipe 212 to move forward and backward.
See shown in Fig. 1, Fig. 5 and Fig. 6, this Automatic continuous rotating punching machine also includes axial-movement devices 40.This axial-movement devices 40 comprises the fixed mount 12 be fixed in frame 10, and this fixed mount 12 is provided with external thread column 41, and external thread column 41 and red needle 30 match.So-called external thread column 41, refer to and have externally threaded cylinder, during use, workpiece is enclosed within this external thread column 41.So-called external thread column 41 and red needle 30 match, and refer to after red needle 30 pairs of workpiece carry out punching press, surface of the work forms pit, and this pit inwardly convexes into salient point in the inner tubular portion of workpiece, the threaded engagement on this salient point and external thread column 41.Like this, when rotary punching apparatus 20 pairs of workpiece punching press pits, workpiece intermittent rotary, then workpiece often rotates once, and namely salient point can rotate along the external screw thread of external thread column 41, and then workpiece intermittent displacement forward.Certainly, frame 10 is now provided with slide rail 11, and pivot joint frame 13 is located on this slide rail 11.
Course of action of the present invention: 1) holding workpiece.Cast workpiece inserts in clamping pipe 212, and the oil cylinder of front and back reciprocating apparatus 213 starts, and piston 2122 pulls in clamping pipe 212 indentation conical pipe 211, thus workpiece clamps by card tooth 2121.Certainly, now the other end of workpiece is enclosed within external thread column 41.2) intermittent rotation is punched.Up and down reciprocatingly device 23 starts, and when it declines, red needle 30 stamps out a pit on workpiece; When it rises, ratchet 22 single direction rotation stirred by driving lever 231, and under the effect of locating piece 221, ratchet 22 is stopped at correct position.Punching press like this forms pit and workpiece rotation is back and forth carried out, and workpiece is formed the pit of whole circle.3) intermittent advance.With step 2) synchronous, workpiece is often stamped out a pit, then workpiece rotates once.That is, workpiece intermittence rotates.This pit forms salient point in workpiece inner wall, the external screw thread occlusion of this salient point and external thread column 41, then, when workpiece intermittence rotates, salient point is along the intermittent displacement of external screw thread, thus the intermittent anterior displacement of workpiece.Like this, workpiece is formed some circle pits.
