Abstract
The utility model relates to a limiting and adjusting device for a stroke of a jacking cylinder of a hydraulic machine. A cylinder body of the jacking cylinder is located in a ground pit under a hydraulic workbench; a jacking cylinder tail rod is arranged at the lower end of the jacking cylinder; a circular ring is arranged at the lower end of the jacking cylinder tail rod; a steel wire rope is fixed on the circular ring; the steel wire rope is wound on a plurality of steel wire rope guiding wheels in turn and reaches a side wall of the hydraulic workbench; a heavy hammer is hung at the tail end of the steel wire rope; a sensing block is fixed on a vertical section of the steel wire rope located on the side wall of the hydraulic workbench; a proximity switch bracket is also fixed on the side wall of the hydraulic workbench; a proximity switch corresponding to the sensing block is mounted on the proximity switch bracket. When the jacking cylinder tail rod moves up and down, the steel wire rope is driven to synchronously move and the sensing block moves up and down along with the steel wire rope. The proximity switch for receiving a signal of the sensing block is mounted on the side wall of the hydraulic workbench, so that an operator does not need to adjust in the ground pit when the relative positions of the proximity switch and the sensing block need to be adjusted.
Description
Technical field
The utility model relates to a kind of hydraulic press, particularly a kind of jacking cylinder of hydraulic press stroke limit adjusting device.
Background technology
In prior art, four-column hydraulic press all possesses automatic ejection, stretch function mostly, is provided with hydraulic die cushion and liftout tank in the chamber of hydraulic table, and the lower surface of described hydraulic die cushion is connected with the piston rod of described liftout tank.Liftout tank sender is realized by approach switch mostly, and liftout tank is installed on workbench inside, ejects in the melt pit that cylinder body is usually located at hydraulic table below.
User's die change, when liftout tank ejection stroke need to regulate, needs to change the position that is arranged on approach switch on angle steel.Operating personnel need to open basic foundation cover plate, enter in Installing machine tool melt pit and regulate, and need two people to coordinate; And the space of melt pit is narrower and small, gathers greasy dirt, easily slips, the smell is awful.
Utility model content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of jacking cylinder of hydraulic press stroke limit adjusting device is provided, simple in structure, can more than ground, directly regulate.
For solving above technical problem, a kind of jacking cylinder of hydraulic press stroke limit adjusting device provided by the utility model, the cylinder body of liftout tank is arranged in the melt pit of hydraulic table below, the lower end of described liftout tank is provided with liftout tank foot piece, the lower end of described liftout tank foot piece is provided with annulus, on described annulus, be fixed with steel wire rope, described steel wire rope is the wrapped side that arrives described hydraulic table on multiple steel wire rope guide wheels successively, the end of described steel wire rope is hung with weight, described steel wire rope is positioned on the vertical section of hydraulic table side and is fixed with sensor block, on the side of described hydraulic table, be also fixed with approach switch support, on described approach switch support, the approach switch corresponding with described sensor block is installed.
With respect to prior art, the utility model has been obtained following beneficial effect: liftout tank foot piece affects steel wire rope synchronizing moving while moving up and down, sensor block is fixed on the vertical section that steel wire rope is positioned at hydraulic table side, move up and down with steel wire rope, the approach switch of accepting sensor block signal is not arranged on below ground, and be mounted in the side of hydraulic table, in the time needing the relative position of adjusting proximity switch and sensor block, do not need operating personnel to regulate in melt pit.
The bottom of described liftout tank is fixed with cylinder bottom wheel bracket, and steel wire rope guide wheel is bottom supported on the bottom of described cylinder bottom wheel bracket, and the steel wire rope between the annulus on described liftout tank foot piece and steel wire rope guide wheel is bottom in plumbness.Keep plumbness from the firm steel wire rope out of liftout tank foot piece, can guarantee and the stroke Complete Synchronization of sensor block, make the adjusting of approach switch position more accurate.
