Abstract
A spindle box lubricating device is characterized in that an eccentric sleeve is arranged on a spindle of a spindle box, a sliding column type oil pump is arranged on one side of the eccentric sleeve, an oil suction port and an oil outlet of the oil pump are respectively provided with a one-way valve and an oil pipe, a sliding column and a spring are arranged in an inner cavity of a pump body, an extending end of the sliding column is tightly attached to the outer circular surface of the eccentric sleeve, and the position and the angle of an oil injection port of the oil outlet are adjustable. The utility model is used for the lubrication of operation part in the nonstandard headstock of lathe, equipment has simple structure, small, assembly easy maintenance, the obvious advantage that lubricated reliability is high.
Description
Technical field
The utility model relates to a kind of lubricating arrangement that is used for nonstandard main spindle box.
Background technology
Main spindle box is as the vitals of lathe, equipment, and its running gear needs sufficient lubrication such as gear, bearing, cam etc.In traditional standard main spindle box, generally design independent oil pump and oil pump shaft, by the drive path of main shaft-gear-oil pump shaft-oil pump,, again distribution of lubrication oil is arrived each lubricant housings by the rotation drive oil pump work of main shaft.This lubrication system architecture is complicated, and it is big to occupy the space, and lubricating reliability is bad, and the assembling maintenance is also inconvenient.For lubricating of nonstandard main spindle box, more not seeing at present has lubricating arrangement preferably.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, assembling lubricating arrangement that is used for nonstandard main spindle box reliably easy to maintenance, lubricated.
This practical technical scheme is in fact: be provided with eccentric bushing on the main shaft of main spindle box, side at eccentric bushing is provided with the slide column type oil pump, the inlet port of this oil pump and oil-out are respectively equipped with check valve and oil pipe, pump housing inner chamber is provided with traveller and spring, and the external part of traveller and above-mentioned eccentric bushing periphery are adjacent to.
Described check valve mainly is made of bellmouth, the little spring that is positioned at the steel ball of bellmouth and compresses steel ball, and wherein the big end of bellmouth communicates with pump housing inner chamber in the inlet port check valve, and the bellmouth small end communicates with pump housing inner chamber in the oil-out check valve; The jet position and the adjustable angle of described oil-out.
The utility model is by the eccentric bushing on main shaft, drive the stretching motion of oil pump traveller by the rotation of main shaft, change oil pump cavity volume and pressure, the check valve of suction, oil-out is opened in turn, realize lubricating oil constantly conveying in a steady stream, adjust the jet position and the angle of hydraulic fluid port oil pipe, just can the effectively lubricating desired area.Compare existing principal axis lubrication system, the utility model has saved driving members such as oil pump shaft and gear, designs simplification, it is little to take volume, assembles easy to maintenancely, and used slide column type oil pump is also more simpler than gear oil pump commonly used, this plant failure rate is little, helps improving lubricated reliability.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
As figure, on the main shaft 14 of main spindle box, be provided with eccentric bushing 13, be provided with the slide column type oil pump in a side of eccentric bushing, be fixed on the wall box by installing hole 9.The inlet port and the oil-out that are positioned at the pump housing 2 both sides are respectively equipped with check valve and oil pipe, and pump housing inner chamber is provided with traveller 12 and spring 3, and traveller slides in fairlead 11, and its external part and eccentric bushing 13 peripheries are adjacent to, dress sealing ring 10 between the fairlead and the pump housing.In the check valve of inlet port, steel ball 6 is positioned at the bellmouth of valve body 5, and the big end of bellmouth communicates with pump housing inner chamber, and little spring 4 is contained between the pump housing 2 and the valve body 5, compresses steel ball; In the check valve of oil-out, steel ball is positioned at the bellmouth of the pump housing 2, and the bellmouth small end communicates with pump housing inner chamber, and little spring is contained between the pump housing 2 and the valve body 15, compresses steel ball.The oil suction copper pipe 7 and the fuel-displaced copper pipe 1 of pump housing both sides are connected on the pump housing by joint 8, the jet position and the adjustable angle of fuel-displaced copper pipe.
Claims (3)
1. main spindle box lubricating arrangement, the main shaft that it is characterized in that main spindle box is provided with eccentric bushing, side at eccentric bushing is provided with the slide column type oil pump, the inlet port of this oil pump and oil-out are respectively equipped with check valve and oil pipe, pump housing inner chamber is provided with traveller and spring, and the external part of traveller and above-mentioned eccentric bushing periphery are adjacent to.
2. by the described main spindle box lubricating arrangement of claim 1, it is characterized in that described check valve mainly is made of bellmouth, the little spring that is positioned at the steel ball of bellmouth and compresses steel ball, wherein the big end of bellmouth communicates with pump housing inner chamber in the inlet port check valve, and the bellmouth small end communicates with pump housing inner chamber in the oil-out check valve.
3. by the described main spindle box lubricating arrangement of claim 1, it is characterized in that the jet position and the adjustable angle of described oil-out oil pipe.
