Abstract
The utility model discloses a closed double-crankshaft precision punching machine. The double-crankshaft precision punching machine comprises a frame and a workbench arranged on one side of the frame; the top of the frame is provided with a balancing stand; the lower end of the balancing stand is fixedly provided with crankshafts arranged in the middle of the frame; the input ends of the crankshafts are connected with a driving mechanism arranged on the outer side of the frame; the output ends of the crankshafts are connected with a worm through a crank connecting rod and a bulb connecting rod sequentially; the output end of the worm is connected with an adjusting plate; the output end of the adjusting plate is connected with sliders and is used for driving the sliders to vertically move. The closed double-crankshaft precision punching machine is simple in structure, high in stability, small in size and low in cost; the output end of the worm is connected with the sliders through the adjusting plate, so that the relative position of the sliders can be conveniently adjusted, displacement errors are reduced and the work efficiency is improved.
Description
Technical field
The present invention relates to a kind of closed-type double action crank press bent axle accurate punching machine.
Background technology
The high-accuracy punch press of closed-type double action crank press bent axle is used widely in tank processed field at present, and double-crankshaft structure is generally all arranged in top or the bottom of punch press, this all needs more supporting construction, and punch press bottom also needs a lot of supporting constructions, can cause like this punch press quality very large, cost is very high, poor stability.And the worm gear in traditional high-accuracy punch press of closed-type double action crank press bent axle is to be directly connected with slide block, and after so long-term operation, it is very large that slide block kinematic error will become, and relative position also should not be adjusted, its operating efficiency is reduced.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides a kind of closed-type double action crank press bent axle accurate punching machine.
The present invention for achieving the above object, adopt following technical scheme: a kind of closed-type double action crank press bent axle accurate punching machine, comprise frame and the workbench that is arranged at frame one side, described frame top is provided with balancer, and described balancer lower end is fixed with the bent axle that is arranged on central rack; The input of described bent axle is connected with the driving mechanism that is arranged on frame outside, and the output of described bent axle is connected with worm gear by crank connecting link, ball head connecting rod successively, and the output of described worm gear is connected with adjustment plate; Described adjustment plate output is connected with slide block, for driving described slide block to move up and down.
Further, described driving mechanism comprises motor, and the output of described motor connects clutch, power transmission shaft and gear wheel successively, and the output of described gear wheel is connected with described bent axle.
Further, the end of described ball head connecting rod is provided with ball cup, and the below of described ball cup is provided with worm gear case.
Further, on described gear wheel, be provided with encoder.
Beneficial effect of the present invention: double-crankshaft structure of the present invention is arranged on the middle part of frame, makes Whole Equipment volume little, and stability is high, and cost is lower; And the output of worm gear is connected with slide block by adjusting plate, can conveniently adjust like this relative position of slide block, reduces displacement error, has improved operating efficiency.
