Abstract
The invention discloses a pressure limit device of a steel ball polishing machine, relating to a steel ball polishing machine. The invention aims at providing a pressure limit device of the ball steel polishing machine; the pressure position device can prevent equipment damage caused by error operation of the operator or leading the pressure of a hydraulic system to exceed regulation in order to improve production efficiency. The technical proposal of the invention is that the pressure limit device of the steel ball polishing machine comprises a hydraulic system; the oil path of the hydraulic system is provided with a pressure switch connected with the power supply of a pump station motor. The pressure switch is arranged on the oil path between a liquid-control check valve and an oil cylinder. The invention is used for a steel ball polishing machine.
Description
Technical field:
The present invention relates to the pressure limiting device of a kind of steel ball finishing machine, particularly a kind of steel ball finishing machine.
Background technology:
The hydraulic system of existing steel ball finishing machine all is not provided with pressure limiting device, only on the tube apparatus operation instructions all the pressure permissible value to the equipment hydraulic system make explicit provisions, but equipment in use since operating personnel in order to devote exclusive attention to output or the force value of faulty operation hydraulic system surpasses regulation and causes equipment breakdowns such as Hydraulic Elements damage, bearing crushing, screw extraction.
Summary of the invention:
The pressure limiting device that the purpose of this invention is to provide a kind of steel ball finishing machine, this pressure limiting device can to prevent operating personnel's faulty operation or to make the pressure of hydraulic system cause device damage above regulation in order enhancing productivity.Technical scheme of the present invention is that a kind of pressure limiting device of steel ball finishing machine comprises hydraulic system, it is characterized in that: a pressure switch is set on the oil circuit of liquid system is connected with the power supply of Electric Machine at Pumping Station.Pressure switch is located on the oil circuit between hydraulic control one-way valve and the oil cylinder.The present invention is owing to be provided with pressure limiting device, thereby has the reliable advantage of stable equipment operation compared with the prior art.
Description of drawings:
Accompanying drawing is a hydraulic system pressure limiting schematic diagram of the present invention.
The specific embodiment:
In conjunction with above accompanying drawing the present invention is elaborated, pumping plant 1, three position four-way directional control valve 2, two position three way directional control valve 3, hydraulic control one-way valve 4, accumulator 5, oil cylinder 6 are arranged in the hydraulic system of existing steel ball finishing machine, on the oil circuit of this system, pressure limiting device is not set, when system oil pressure surpasses setting, will cause device damage, be head it off, a pressure switch 7 be connected with the Electric Machine at Pumping Station power supply (referring to accompanying drawing) is set on the oil circuit between the hydraulic control one-way valve 4 of hydraulic system and the oil cylinder 6.Therefore, when no matter any reason caused the oil pressure of hydraulic system to surpass setting, the motor power of pumping plant was cut off in pressure switch 7 actions, and system quits work, and has guaranteed the safety of equipment.
