Description
Technical field
The utility model relates to a kind of pressure-detecting device, is a kind of oil pocket pressure-detecting device, is particularly suitable for detecting heavy machine tool hydrostatic slideway oil pocket pressure.
Background technology
What current heavy machine tool guide rail both domestic and external adopted mostly is static-pressure guide rail structure.But hydrostatic slideway that is large-scale or heavy machine tool has many fuel feeding paths usually, hydrostatic slideway needs the oil supply system of a set of complexity, all may there is deviation or problem in the fuel feeding situation of every bar fuel feeding path, this makes maintenance and the maintenance quite difficulty of whole static pressure oil circuit, take time and effort, maintenance worker's labour intensity is very large.So be badly in need of a kind of device that accurately can detect static-pressure oil chamber pressure fast, improve the efficiency that static-pressure system is safeguarded and overhauled.
Summary of the invention
The purpose of this utility model is according to shortage of the prior art and deficiency, provides a kind of device that accurately can detect oil pocket pressure fast, improves the efficiency that static-pressure system is safeguarded and overhauled.
The utility model provides a kind of oil pocket pressure-detecting device be arranged on high-precision numerical control machine, comprise multi-head pump, oil path block, pressure switch and pressure measuring tie-in, described multi-head pump is arranged on slide, hydraulic oil fuel feeding oil pipe from system is connected with multi-head pump, and hydraulic oil is divided into the hydraulic oil on more than the identical road of flow by point oilgear in multi-head pump; Slide is provided with oil path block, and the hydraulic oil that the above flow in road separated by multi-head pump is identical is connected with each oil-feed oil circuit of oil path block, forms the oil circuit of one or more; Each fuel-displaced oil circuit of oil path block is connected with each static-pressure oil chamber, flows out, enter into each static-pressure oil chamber from the fuel-displaced oil circuit of oil path block; One or more oil circuit of described oil path block is provided with pressure switch; Oil path block is provided with the pressure measuring tie-in corresponding to each bar oil circuit, pressure measuring tie-in is connected with pressure tester.
Oil pocket pressure-detecting device described in the utility model, the beneficial effect that Yan Suoneng produces for prior art is, effectively can overcome maintenance and the detection difficult of static pressure oil circuit, the problem that maintenance worker's labour intensity is large, the device accurately detecting static-pressure oil chamber pressure fast can be realized, improve the efficiency of static-pressure system maintenance and maintenance.Also have that structural principle is simple, functional reliability is high simultaneously, original lathe carries out the low cost and other advantages improved.
