Abstract

The utility model relates to an upper hydraulic die cushion range device for a single-action hydraulic machine without a displacement sensor. The upper hydraulic die cushion range device in the prior art is arranged underground, and has the defects that the production schedule is seriously influenced because a pit cover plate needs to be lifted during regulation, the space is narrow, the vision is fuzzy, and a overtravel-limit switch is inconveniently regulated and can be regulated by needing more than two people, and the overtravel-limit switch can not be detected once damaged to easily cause safety accidents. The technical scheme provided by the utility model is as follows: the structure of a movable working platform is changed, and the upper hydraulic die cushion range device is directly arranged above the ground. The utility model has the beneficial effects of being more convenient for regulation of the overtravel-limit switch, reducing time, increasing efficiency, and being easy to maintain because failures can be immediately found once occurring.

Description

Not with the single action hydraulic press of displacement transducer with overhead hydraulic die cushion stroke limit device
Technical field
The utility model belongs to a kind of mechanical part, relate in particular to a kind of not with the single action hydraulic press of displacement transducer with overhead hydraulic die cushion stroke limit device.
Background technology
Be not installed in below ground with the single action hydraulic press hydraulic die cushion stroke limit device of displacement transducer in the existing technology, adjustment need be raised melt pit cover plate, narrow space; Blurred vision; The adjustment stroke switch is very inconvenient, and needs could accomplish more than two people, has a strong impact on manufacturing schedule; Switch damages can not be discovered for the moment, causes security incident easily.
Summary of the invention
The purpose of the utility model is to above-mentioned deficiency, provide a kind of simple and easy to do a kind of not with the single action hydraulic press of displacement transducer with overhead hydraulic die cushion stroke limit device:
A breach is opened at travelling table or stationary work-table rear portion, built-in overhead hydraulic die cushion stroke limit device; This device is installed on the hydraulic die cushion through cross bar and screw; Optoelectronic switch is installed in the groove of travel switch support, is installed on the base through screw together again.
For better effect: travelling table or stationary work-table rear side are provided with mounting groove along the cross bar above-below direction.
Overhead hydraulic die cushion stroke limit device is installed in the rightabout of travelling table moving direction.
Overhead hydraulic die cushion stroke limit device outer setting safty shield.
The technical scheme that the utility model proposes is the structure change with travelling table, and this device is directly installed on more than the ground.The good effect of the utility model is that the travel switch adjusting is very convenient, the minimizing time, raises the efficiency, and breaks down and can in time find, easily maintenance.
A breach is opened at the travelling table rear portion, built-in overhead hydraulic die cushion stroke limit device; This device is installed on the hydraulic die cushion through cross bar and screw; Optoelectronic switch is installed in the groove of travel switch support, is installed on the base through screw together again.Adjustment optoelectronic switch position can regulator solution pressure pad stroke L.Overhead hydraulic die cushion stroke limit device is installed in the reverse of travelling table moving direction, in order to avoid interfere with the power transmission shaft of travelling table.
Description of drawings
Come further to illustrate below in conjunction with the accompanying drawing and the specific embodiment:
Fig. 1 is the structural representation of the utility model one embodiment
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The utility model comprises travelling table 1, and its workbench also can be set to stationary work-table, hydraulic die cushion 2, base 3, cross bar 4, travel switch support 5, protective cover 6, optoelectronic switch 7.A breach is opened at travelling table 1 rear portion, be used to install overhead hydraulic die cushion stroke limit device.Be specially cross bar 4 and be installed on the hydraulic die cushion 2, move up and down with hydraulic die cushion 2 through screw; Optoelectronic switch 7 is installed in the groove of travel switch support 5, is installed on the base 3 through screw together again, the outside protective cover 6 of installing, and adjustment optoelectronic switch 7 positions can regulator solution pressure pad stroke L.
In sum; This example is merely an embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
