Abstract
The invention discloses a balancing device for a floor boring spindle box, which is used for realizing the balance of a spindle box of a machine tool comprising a box-type column. The balancing device comprises a hydraulic oil cylinder arranged at the front of the box-type column in the vertical direction, and also comprises a supporting component arranged at the end part of a piston rod of the hydraulic oil cylinder, wherein the spindle box of the machine tool is connected with the hydraulic oil cylinder through the supporting component, and the hydraulic oil cylinder is positioned in the middle of the front of the box-type column; in the rising process of the spindle box, oil is fed into a rod chamber of the hydraulic oil cylinder, and the piston rod generates pull force to balance the gravity of the spindle box; and in the falling process of the spindle box, the oil is discharged from the rod chamber of the hydraulic oil cylinder, and the piston rod generates the pull force to balance the gravity of the spindle box. The balancing device has the advantages that: the structure is simple, the weight is light, the mass of the whole machine tool is effectively decreased, especially the mass of moving parts is decreased, the balancing effect is good, and the installation and maintenance are convenient.
Description
Technical field
The present invention relates to lathe headstock balancing technique field, particularly relate to a kind of bascule of floor boring spindle box.
Background technology
The quality of balance has important impact to machine tool capability.Balance mode about the main spindle box of lathe has varied, such as servomotor amplification balance, counterweight balance, oil pressure balance etc., and various balance mode has oneself pluses and minuses.At present, main spindle box balance in floor-type milling & boring machine adopts weight to balance mostly, weight is arranged on column inside, be connected with main spindle box by steel wire rope, realize main spindle box balance, such as a kind of balancing motion shock-absorbing device for heavy punch disclosed in Chinese patent CN 101879688A, but because weight volume, quality are larger, larger inertia impact can be produced, lathe also can be caused on the other hand to move integrally part quality and strengthen, thus have a strong impact on the fast-response of lathe.Chinese patent CN 201279593Y discloses a kind of lathe headstock automatic balancing structure, comprise air accumulator and compensating cylinder, constant pressure pressure-reducing valve and pressure regulator valve are housed between air accumulator and compensating cylinder, this kind utilizes pneumatic equalizer greatly can reduce the quality of complete machine tool with the technical scheme of pneumatic cylinder replacement weight, also good response is had, but due to self limitation pneumatic, pneumatic equalizer is applied in large-scale and heavy machine tool at present or seldom.
Summary of the invention
For above-mentioned Problems existing, the object of this invention is to provide a kind of bascule of floor boring spindle box, under the prerequisite of active balance main spindle box weight, the weight of moving component can be alleviated to a great extent, improve the fast-response of lathe.
The object of the invention is to be achieved through the following technical solutions:
A bascule for floor boring spindle box, for realizing the balance of lathe headstock, lathe comprises box column, wherein, comprises the hydraulic jack being arranged on box column face portion, and described hydraulic jack is arranged along the vertical direction of box column; Also comprise a support unit, described support unit is arranged on the piston rod end of described hydraulic jack, and lathe headstock is connected with described hydraulic jack by described support unit; Described hydraulic jack is positioned at the centre position of box column face portion; In main spindle box uphill process, the oil-feed of described hydraulic jack rod chamber, described piston rod produces pulling force with the gravity of balancing main shaft case; In main spindle box decline process, the oil extraction of described hydraulic jack rod chamber, described piston rod produces the gravity of tension balanced main spindle box.
Further, described support unit is a support.
Further, described support unit is arranged on the piston rod end of described hydraulic jack by locking nut.
Further, described hydraulic jack is fixed on the face portion of box column by attaching parts, and described attaching parts comprise supporting base and bolt.
Further, the cross section of described supporting base is " Ω " type.
Further, lathe headstock is bolted on described support unit.
Compared with the prior art, beneficial effect of the present invention is: structure is simple, and quality is light, effectively reduces complete machine tool quality, especially the quality of moving component, good balance effect, and easy to installation and maintenance.
Accompanying drawing explanation
Fig. 1 is the front view of the bascule of floor boring spindle box of the present invention;
Fig. 2 is the side view of Fig. 1.
Detailed description of the invention
Below in conjunction with schematic diagram and concrete operations embodiment, the invention will be further described.
As depicted in figs. 1 and 2, the bascule of floor boring spindle box of the present invention is for realizing the balance of lathe headstock 00, lathe comprises box column 0, and bascule of the present invention specifically comprises the hydraulic jack 1 being arranged on box column 0 face portion, and hydraulic jack 1 is arranged along the vertical direction of box column 0.Hydraulic jack 1 is fixed on the face portion of box column by attaching parts 2, attaching parts 2 comprise supporting base 21 and bolt 22, the cross section of supporting base 21 can be " Ω " type etc., specifically determine according to the shape of cross section of hydraulic jack 1, supporting base 21 can by material one machine-shapings such as cast irons, bolt 22 commercially easily obtains, to facilitate realization of the present invention.
Continue referring to shown in Fig. 2, bascule of the present invention also comprises a support unit 3, support unit 3 is arranged on the piston rod end of hydraulic jack 1, and lathe headstock 00 is connected with hydraulic jack 1 by support unit 3, and hydraulic jack 1 is positioned at the centre position of box column 0 face portion.Support unit 3 is a support, and support cylinder iron can wait the machine-shaping of material one, and this is the common practise of those skilled in the art, does not repeat them here.Lathe headstock 00 is bolted on support unit 3, and support unit 3 is arranged on the piston rod end of hydraulic jack 1 by locking nut 4, the active force produced is delivered on main spindle box 00 by support 3 during the piston rod movement of hydraulic jack 1.In the process of bascule effect, piston rod is flexible with the motion of main spindle box 00, realize the balance of main spindle box 00 optional position on its stroke, piston rod end is directly connected with main spindle box 00 by support 3, this just makes the stroke of piston rod namely be main spindle box stroke, when in main spindle box 00 uphill process, rod chamber oil-feed in hydraulic jack 1, piston rod produces pulling force with the gravity of balancing main shaft case 00; When in main spindle box 00 decline process, rod chamber oil extraction in hydraulic jack 1, piston rod produces the gravity of tension balanced main spindle box.
To sum up, the balance device structure of floor boring spindle box of the present invention is simple, and quality is light, effectively reduces complete machine tool quality, especially the quality of moving component, good balance effect, and easy to installation and maintenance.
Be described in detail specific embodiments of the invention above, but the present invention is not restricted to specific embodiment described above, it is just as example.To those skilled in the art, any equivalent modifications and substitute also all among category of the present invention.Therefore, equalization conversion done without departing from the spirit and scope of the invention and amendment, all should contain within the scope of the invention.
