Description
Technical field
The utility model relates to a kind of shoemaking machinery, particularly a kind of main shaft linkage of hydraulic pressure four post plane blanking machines.
Background technology
At present, the hydraulic pressure four post plane blanking machines that shoe-making industry uses, its main shaft linkage mainly is made up of column, pole slide and main shaft, and four root posts are located at respectively on four corners of body, and the upper end of column is connected with top board.Two root posts of body both sides are made it to be connected by a pole slide respectively, are connected by main shaft between the pole slide of both sides.Pass through slide one slide rail guiding movement between pole slide and the body.Two pole slides are driven by two hydraulic jacks being located at the body both sides respectively.The piston rod earrings of oil cylinder is connected with the pole slide by straight pin, by connecting rod the piston rod earrings is connected with main shaft again, connects four columns drives of two oil cylinder piston earrings drivings top boards by main shaft and moves up and down.The blanking machine of said structure, owing to adopt two hydraulic oil cylinder driving, column is connected by the bearing slide bar, main shaft is connected by connecting rod with oil cylinder, therefore, and complex structure, cost is big, and power consumption is high, and power of motor is big, the installation and maintenance inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is, the deficiency that overcome complex structure in the prior art, needs the heavy wool cylinder to drive provides a kind of main shaft linkage of simple in structure, hydraulic pressure four post plane blanking machines that single cylinder drives.
Technical solution of the present utility model is, is respectively equipped with guide upright post on four corners of body, fixedlys connected with top board in the upper end of guide upright post, and main shaft is located at the downside of body, and the middle part of main shaft and both sides are respectively equipped with bent axle pendulum plate.The bent axle pendulum plate at main shaft middle part is connected with the piston rod of hydraulic jack, and the bent axle pendulum plate of main shaft both sides is connected with top board by connecting rod respectively.Two of connecting rod is flexibly connected by the bent axle pendulum plate and the top board of pin and main shaft both sides respectively.The crankshaft-link rod of oil cylinder by main shaft and both sides directly drives top board and moves up and down.
In order to make spindle power realize that little input exports greatly, the centre-to-centre spacing of main shaft middle part bent axle pendulum plate is greater than the centre-to-centre spacing of main shaft two ends bent axle pendulum plate.
Connecting rod is made of last connecting rod and lower link, is provided with Adjusting bolt Adjusting screw between the upper and lower connecting rod and makes it to be connected also adjustable.
The utility model has the advantages that, by the crankshaft connecting rod system of main shaft, and the long and short ratio of secondary bent axle pendulum plate centre-to-centre spacing, realize single hydraulic oil cylinder driving, the little input of power is exported greatly, identical, the stable working of each pressure spot pressure of top board, simple in structure, reduce cost, easy to maintenance.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
Be respectively equipped with four guide upright posts 1 on four corners of body 13, the upper end of guide upright post 1 and top board 2 are fixedly connected and can move up and down with top board 2 relative bodies 13.Main shaft 9 is located at the downside of body 13.Main shaft 9 is provided with three bent axle pendulum plates 10,8, lays respectively at the middle part and the both sides of main shaft 9, and the bent axle pendulum plate 10 at middle part is the power intake of main shaft 9, and the bent axle pendulum plate 8 of both sides is the clutch end of main shaft 9, thereby makes main shaft 9 constitute the secondary bent axle.Be respectively equipped with crankpin 11,7 on the bent axle pendulum plate 10,8.The bent axle pendulum plate 10 at main shaft middle part directly is connected with the piston rod of hydraulic jack 12, and the bent axle pendulum plate 8 of main shaft both sides is respectively by connecting rod 4,6 and top board 2 connections mutually.One of its connecting rod 4,6 is passed through straight pin 3 and top board 2 flexible connections, and the other end is put plate 8 by crankpin 7 and bent axle and flexibly connected
For the power output that makes main shaft 9 greater than input power, bent axle pendulum plate 10 centre-to-centre spacing at main shaft middle part are greater than the centre-to-centre spacing of main shaft two ends bent axle pendulum plate 8.
In order to make the adjustable length of connecting rod 4,6, connecting rod 4,6 is made of last connecting rod 4 and lower link 6, makes it to be connected by an Adjusting bolt Adjusting screw 5 between last connecting rod 4 and the lower link 6, and can regulate the length of upper and lower connecting rod 4,6.
Power transmission of the present utility model: hydraulic jack 12 drive shaft 9 are rotated, and main shaft 9 moves up and down by connecting rod 4, the 6 direct top board works 2 that promote at two ends again, thereby realize the working motion of blanking machine.
