The specific embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the cold machine that strikes of spline provided by the invention is described in detail.
Embodiment
With reference to Fig. 1-Fig. 3, the cold machine that strikes of the spline of present embodiment, comprise support 17, fuselage 18, the main transmission support fixture 8 of unifying, it also comprises main motor 14, X-axis motor 1, Z axis motor 5, two roll main shafts 7, roll 6 and workpiece transmission systems, described two roll main shafts, 7 symmetrical installations, a roll 6 respectively is installed on two roll main shafts 7, and described support fixture 8 is positioned on the center line of two roll main shafts 7, has clamped workpiece 16 on the support fixture 8.Described main transmission comprises B through-drive chain 12, and B through-drive chain 12 1 ends are connected with top spare master motor 14, and the other end is connected with roll main shaft 7.The cold machine that strikes of spline also comprises X-axis driving-chain 2 and feed screw nut 3, and described X-axis motor 1, X-axis driving-chain 2, feed screw nut 3, roll main shaft 7 connect successively.Described workpiece transmission system comprises workpiece interrupted division movement transmission and workpiece linear reciprocating motion transmission system, workpiece interrupted division movement transmission comprises indexing mechanism driving-chain 13 and indexing mechanism 9, and described main motor 14, indexing mechanism driving-chain 13, indexing mechanism 9 are connected with support fixture successively and are connected.Described workpiece linear reciprocating motion transmission system comprises Z-axis transmission chain 4, ball-screw 11 and slide 10, described Z-axis transmission chain 4 is connected with Z axis motor 5, described ball-screw 11 is installed on the fuselage 18, and slide 10 is installed on the ball-screw 11, and support fixture 8 links to each other with slide 10.
The cold machine that strikes of spline is by realizing the cold knock shape processing of workpiece with the underdrive motion: 1, at first main electrical power rotation, and pass motion to B through-drive chain, B through-drive chain drives two roll main shafts and does reverse rotation, the reverse rotation of two roll main shafts drives again the reverse rotation of two rolls, and roll is realized separately rotatablely moving around center roll main shaft; 2, roll also has reciprocal circular motion when the roll main shaft rotates, the rotation of X-axis electrical power, and will rotatablely move and pass to the feed screw nut by the X-axis driving-chain, the feed screw nut drives two roll main shafts and does oppositely back and forth circular motion around central shaft 15, thereby the roll that drives on the roll main shaft is done oppositely back and forth circular motion; 3, processed workpiece, under the drive of main motor and Z axis motor, do simultaneously interrupted division motion and linear reciprocating motion, main motor rotates and passes motion to indexing mechanism by the indexing mechanism driving-chain, indexing mechanism drives workpiece rotating and does dividing movement, when workpiece is in calibration state at intermittence, the Z axis motor drives the ball-screw motion by the Z-axis transmission chain, and ball-screw drives slide front and back motion on fuselage, thereby the workpiece that drives on the slide seesaws.Make the reciprocating roll of reverse circumference, when moving to position that workpiece contacts, because two rolls self are around the reverse rotation campaign of roll main shaft, roll with surface of the work contact in workpiece is carried out relative knocking, in the process of knocking, the roll main shaft rotates a circle around circular path, drive roll and knock workpiece once, simultaneously workpiece is done axial feed motion under the Z axis driven by motor, and after knocking, calibration is once under the drive of indexing mechanism for workpiece.
The cold machine that strikes of spline, working (machining) efficiency is high, than the traditional metal cutting technology, can raise the efficiency 20～30 times; By two rolls workpiece is carried out repeatedly beatening, do not produce smear metal, metal structure is fine and closely woven, and bending strength, the fatigue strength of workpiece significantly increase, the good combination property of gained part, and the life-span can be improved 2～3 times; Economical with materials, cold knocking is material for transfer rather than excision material, compare with traditional machining process, but tooth section economical with materials 20%～40% reduced production cost.
