Description

The hydraulic feed voltage-stabilizing system of drill unit
Technical field
The utility model is a kind of voltage-stabilizing system, particularly a kind of hydraulic feed voltage-stabilizing system of drill unit, for industries such as machinery industry, electric power, steel construction, welding and automatic assembly lines.
Background technology
Along with the progress of production technology, the application of high speed drill is more and more extensive.But in drill for high-speed processing, from chisel edge exposes workpiece, cutting resistance can reduce gradually, the feed speed thereupon producing a jumping characteristic increases (see accompanying drawing one: the drilling processing feed speed curve not adopting voltage stabilizing oil circuit).This feed speed accelerated suddenly at boring end, the FAQs bringing us has two: the cutting that 1. usually can destroy drill bit is tough, and collapsing that namely we often say is tough.This just makes drilling process the non-cutting time adding a lot of coping drills, decreases the service life of drill bit, significantly limit the performance of the high efficiency ability of high-speed machine tool own.2. feed speed is significantly accelerated suddenly, and oil motor can be made to occur superpressure rotation phenomenon, can make the main shaft all standing of rotation, cause fractureing of drill bit when superpressure is serious, and this, concerning expensive inner-cooled high speed bit, adds production cost greatly.
How preventing boring end from occurring velocity shock phenomenon, extend the service life of drill bit, play the operating efficiency of high-speed drilling machine to greatest extent, is the new problem that the processing of current drill for high-speed needs to solve.
Utility model content
The utility model mainly solves the deficiencies in the prior art, compact conformation, completely eliminates the hydraulic feed voltage-stabilizing system of the drill unit of the phenomenon of the feed speed sudden change produced because cutting resistance reduces at boring end.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of hydraulic feed voltage-stabilizing system of drill unit, comprise compressed oil cylinder mechanism, feed cylinder mechanism, fuel tank, backflow oil circuit, supply oil circuit and overflow oil circuit, described compressed oil cylinder mechanism comprises compressed oil cylinder, guide rail cylinder, compress backflow oil circuit and compress supply oil circuit, described compression supply oil circuit successively and three-position four-way electromagnetic directional valve, stacking type hydraulic control check valve, stacked unidirectional throttle valve is connected with compressed oil cylinder, described compression backflow oil circuit successively and three-position four-way electromagnetic directional valve, stacking type hydraulic control check valve, stacked unidirectional throttle valve is connected with compressed oil cylinder, one end of described guide rail cylinder is connected with the oil inlet end of compressed oil cylinder, the other end of described guide rail cylinder is connected with the backflow end of compressed oil cylinder, described feed cylinder mechanism comprises feed cylinder, feeding for oil supply oil circuit and feeding backflow oil circuit, described feeding is connected with feed cylinder with three-position four-way electromagnetic directional valve I, speed speed control valve, stacked unidirectional throttle valve I successively for oil supply oil circuit, and described feeding backflow oil circuit is connected with feed cylinder with three-position four-way electromagnetic directional valve I, speed speed control valve, stacked unidirectional throttle valve I successively, described fuel tank is provided with pump group, described pump group is connected with feed cylinder mechanism with compressed oil cylinder mechanism respectively by supply oil circuit, described fuel tank is connected with backflow oil filter, described backflow oil filter is connected with wind cooling oil cooler, and described wind cooling oil cooler is connected with feed cylinder mechanism with compressed oil cylinder mechanism respectively by backflow oil circuit.
As preferably, described compression backflow oil circuit and compression supply between oil circuit and are provided with shockproof electrical contact manometer mileage, described feeding refluxes between oil circuit for oil supply oil circuit and feeding and is provided with stacked compression release valve, be provided with between described pump group and supply oil circuit and pull formula check valve, described formula of pulling check valve is connected with one end of electromagnetic relief valve with between pump group, the other end of described electromagnetic relief valve is connected with backflow oil circuit, is provided with proportional flow pressure valve in described overflow oil circuit.
Utilize the characteristic of pressure-reducing valve secondary oil circuit constant pressure, ensure that drill bit work speed not by the impact of P mouth pressure change.Thus obtain one desirable, close to constant rate curve.Magnetic valve is utilized to switch the bypass condition of choke valve, to control the switching of the F.F. of drill bit, rewind, work speed, and can stable adjust flux be maintained, the impact making it not be subject to out oiler pressure to change, accurately control the feed speed of feed cylinder rodless cavity.
Effectively ensure that the stable of feed speed in drill for high-speed processing.Eliminate the phenomenon of boring end drilling velocity jump, prevent end add the damage of drill bit in man-hour and fracture, effectively extend the service life of drill bit, reduce processing cost.Significantly decrease the non-cutting time of drilling processing, effectively ensure that the high efficiency performance of high-speed drilling machine.Effectively stop the phenomenon that oil motor superpressure is rotated, extend the service life of Hydraulic Elements.Improve the geometric accuracy of boring.Eliminate and occur oval phenomenon because boring end drilling velocity jump forms aperture end.
Therefore, the hydraulic feed voltage-stabilizing system of the drill unit that the utility model provides, compact conformation, stability is high, reduces use cost, improves performance accuracy.
