The stroke regulation device is fixedly arranged above the oil cylinder, so the processing is simple; the top of the oil cylinder body is not provided with a hole, so the oil cylinder is completely sealed, the phenomena of oil leakage and the like cannot occur, and the maintenance cost is lowered.
Description
Technical field
The utility model relates to a kind of ram travel governor motion of hydrolic plate bender, relates in particular to a kind of ram travel governor motion of turning round a synchronous hydraulic plate bending machine.
Background technology
Turning round has a ram travel governor motion in the synchronous hydraulic plate bending machine, the effect of this mechanism is to drive slide block with oil cylinder to move up and down, and limits slide block in the position of bottom dead centre, thus the stroke of adjusting slider.What existing ram travel governor motion adopted is overall structure, roughly divide two kinds of forms: first kind of form, stroke control mechanism is installed on the piston and the piston rod cavity of oil cylinder, piston and piston rod inside are hollow, its operation principle is by the reducing gear on the oil cylinder top, the axle that drives a vertical direction rotates, this root axle is by the hole on the cylinder body top, enter in the cylinder body and piston cavity, the stroke control mechanism that drive is installed in the oil cylinder piston bar moves up and down, and reaches the purpose of adjusting slider lower dead point position.Its structure is very complicated, and processing, installation, maintenance are all very difficult, especially the hole on the oil cylinder top, because its requirement on machining accuracy height, installation accuracy requires high, will add a fairlead in the oil cylinder apical pore, this fairlead can wear and tear, and the back oil leakage phenomenon that dispatches from the factory is very general; Second kind of form, be that stroke control mechanism is installed on cylinder body top, piston is solid, but piston has connecting rod directly to stretch out the oil cylinder end face on the top, and passing stroke control mechanism, a nut is arranged at the connecting rod top, is fixed on the connecting rod, the ram travel governor motion is under driven by motor, and limited block moves up and down.During work, the lower plane of connecting rod top nut is pressed on the limited block on the plane, comes the adjusting slider stroke thus.It also has a shortcoming except that having the identical shortcoming with first kind of form, because of on the piston top connecting rod being arranged, has reduced effective area in the oil cylinder, so cylinder body is bulky, the cost height is processed more difficult.
Summary of the invention
The utility model is at the problem of existing ram travel governor motion processing difficulties, easy oil leakage, carried out research and improved, and provides a kind of and processes simply, the ram travel governor motion of the hydrolic plate bender of not easy oil leakage.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The ram travel governor motion of hydrolic plate bender, comprise slide block, oil cylinder and stroke adjusting device, have rectangular opening on the described slide block, described oil cylinder and stroke adjusting device are positioned at described rectangular opening, described slide block is fixedlyed connected with the piston rod of described oil cylinder, and described stroke adjusting device is fixedly set in described oil cylinder top.
Further, described rectangular opening top margin is provided with positioning boss.
Described stroke adjusting device comprises worm gear seat, worm gear, worm screw and adjusting screw(rod), the top of described worm gear seat is provided with the step blind hole, described worm gear is arranged on the step surface of described step blind hole, described adjusting screw(rod) is threadedly connected in the described worm gear, and described worm screw passes described worm gear seat and cooperates with described worm gear.
Described slide block is fixedlyed connected with the piston rod of described oil cylinder by connecting pin and attachment screw.
Technique effect of the present utility model is:
1, the utility model changes the branch body structure into by overall structure of the prior art, has rectangular opening on the slide block, and the rectangular opening bottom is an oil cylinder, and stroke adjusting device is fixedly set in the oil cylinder top, and processing is simple; And cylinder body does not have the hole on the top, and oil cylinder seals fully, the situation of leakage of oil can not occur, has reduced maintenance cost.
2, the rectangular opening top margin is provided with positioning boss, has reduced machined surface, can guarantee that stroke adjusting device contacts reliably with positioning boss, has improved the precision of adjusting device.
3, stroke adjusting device is made up of worm gear, worm screw and adjusting screw(rod), and is simple in structure, reliable.
4, slide block is fixedlyed connected with the piston rod of oil cylinder by connecting pin and attachment screw, and connection is simple, reliable, and cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
See Fig. 1 and Fig. 2, the utility model is a kind of ram travel governor motion of turning round a synchronous hydraulic plate bending machine, comprises slide block 4, oil cylinder 1 and stroke adjusting device.
See Fig. 2, slide block 4 is a rectangular slab, has rectangular opening 13 on it, and four angles of rectangular opening 13 are fillet, and the top margin of rectangular opening 13 is provided with positioning boss 12.Oil cylinder 1 and stroke adjusting device are positioned at rectangular opening 13.
See Fig. 1, oil cylinder 1 is positioned at the bottom of rectangular opening 13, and the piston rod 2 of oil cylinder 1 is the oil cylinder cover 3 of outstanding oil cylinder 1 downwards.Movable sealing between oil cylinder cover 3 and the piston rod 2.The bottom of piston rod 2 is processed with screwed hole, connects pin 5 and fixedlys connected with piston rod 2 by attachment screw 6.Connecting pin 5 is cylinder, is positioned at the below of rectangular opening 13, is assemblied on the slide block 4, and slide block 4 is fixedlyed connected with the piston rod 2 of oil cylinder 1.
See Fig. 1 and Fig. 2, stroke adjusting device comprises worm gear seat 7, worm gear 9, worm screw 8 and adjusting screw(rod) 10.Worm gear seat 7 is fixed in the top of oil cylinder 1 by hold-down screw 11.The top of worm gear seat 7 is provided with the step blind hole, and worm gear 9 is arranged on the step surface of step blind hole.Being threadedly connected in the worm gear 9 of adjusting screw(rod) 10, worm screw 8 are passed worm gear seat 7 and are cooperated with worm gear 9.
