Abstract

A hydraulic oil cylinder and sliding block connecting device with a separated flange structure comprises a flange and a screw assembly; the flange is of a separated structure and is divided into at least two sections; after the flange is combined together, an inner hole of the flange is divided into an upper portion and a lower portion, where the diameters of the upper portion and the lower portion are different from each other; the diameter of the upper portion hole is smaller than that of the lower portion hole; a step surface is formed inside the flange; the bottom end of a piston rod of a hydraulic oil cylinder comprises a circle of step surface which protrudes from the lateral surface of the piston rod; the step surface of the flange is just clamped in the step surface of the piston rod; a plurality of counter bored holes are formed in each section of flange along the circumference; the screw assembly is further screwed into a screw hole which is formed in a sliding block after being screwed into the counter bored holes. According to the hydraulic oil cylinder and sliding block connecting device with the separated flange structure, the connection of the piston rod of the hydraulic oil cylinder and the sliding block of a hydraulic press is achieved through the separated flange; the flange is connected with the piston rod through the step surfaces and accordingly the contact area is increased and the reliability of the connection is improved; the structure is simple, the manufacturing is convenient, and the problem that the flange is easy to fracture under unbalanced loading conditions is effectively solved.

Description

Hydraulic jack and the slide block connector with split flange arrangement
Technical field
The utility model relates to the mechanical connecting device in hydraulic press, relates in particular to hydraulic jack and slide block connector.
Background technology
Current, slider of hydraulic press and cylinder connecting device generally adopt integral (type) flange, and flange is connected with piston rod by screw thread, and flange is connected with slide block by screw assembly; When hydraulic press easily causes flange fracture in the situation that unbalance loading is serious, after flange fracture, due to gapped between screw assembly and flange hole, cause the flange of fracture loose, cause the disengaging between flange and piston rod, initiation solution press security incident.
Utility model content
Technical problem to be solved of the present utility model is to provide a kind of effective unbalance loading operating mode the lower flange easily hydraulic jack with split flange arrangement and slide block connector of the problem of fracture of having solved.
The utility model solves the problems of the technologies described above by the following technical solutions: a kind of hydraulic jack and slide block connector with split flange arrangement, comprise flange and screw assembly, described flange is Split type structure, be divided at least two lobes, flange altogether after, its endoporus is divided into the different two parts of upper and lower diameter, the diameter in upper part hole is less than the diameter in lower part hole, at the inner step surface that forms of flange, the bottom of the piston rod of described hydraulic jack has the step surface of the side surface of the outstanding piston rod of a circle, the step surface of flange is just stuck on the step surface of piston rod, Mei Ban flange all offers several counterbores along circumference, screw assembly screws in after counterbore, in the screw that further screw-in slide block is offered.
Further optimize, described flange is divided into 4 lobes.
Further optimize, the lower plane of described flange and the upper surface of slide block have certain gap.
The utility model has the advantage of: by split flange, realized being connected of cylinder piston rod and slider of hydraulic press, between flange and piston rod, adopt step surface to be connected, increased contact area, improved the reliability connecting, and simple in structure, easily manufactured, effectively solved the easily problem of fracture of unbalance loading operating mode lower flange.
Accompanying drawing explanation
Fig. 1 the utlity model has the hydraulic jack of split flange arrangement and the application structure figure of slide block connector.
Fig. 2 is flange arrangement plane.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Shown in Fig. 1 and Fig. 2, the utlity model has hydraulic jack and the slide block connector of split flange arrangement, comprise flange 1 and screw assembly 2.
Described flange 1 is Split type structure, is divided at least two lobes, shown in Fig. 2 for being divided into 4 lobes.Flange 1 altogether after, its endoporus is divided into the different two parts of upper and lower diameter, the diameter in upper part hole is less than the diameter in lower part hole, makes flange 1 inside have a step surface 12.The bottom of the piston rod 10 of described hydraulic jack has the step surface 102 of the side surface of the outstanding piston rod 10 of a circle.The step surface 12 of flange 1 is just stuck on the step surface 102 of piston rod 10.
Mei Ban flange 1 all offers several counterbores 14 along circumference, screw assembly 2 screws in after counterbore 14, in the screw that further screw-in slide block 20 is offered, realized being connected of the connection of flange 1 screw assembly 2 and screw assembly 2 and slider of hydraulic press 20, thereby realized being connected of cylinder piston rod 10 and slider of hydraulic press 20.
Optimize, the lower plane of flange 1 can not contact with slide block 20, and the lower plane of flange 1 and slide block 20 upper surfaces have certain gap, to improve the reliability of flange 1.
Above-mentioned connected mode, independently part all can be independent completes linkage function for each that makes flange 1, even flange 1 fracture, the part of fracture still can be stuck on piston rod 10 by step surface, can not cause the disengaging between flange and piston rod; In addition, the step surface adopting between flange 1 and piston rod 10 is connected has increased contact area, has improved the reliability of connection.This structure is specially adapted to being connected between cylinder piston rod and slide block under operating mode that hydraulic press unbalance loading is serious.
The foregoing is only the preferred embodiment that the utility model is created; in order to limit the utility model, do not create; any modification of doing within all spirit of creating at the utility model and principle, be equal to and replace and improvement etc., within all should being included in the protection domain that the utility model creates.
