Below, the bracing or strutting arrangement of the utility model embodiment is described with reference to the accompanying drawings in detail.The following description uses upper and lower, all around shown in arrow in figure.
Embodiment 1
Lathe 1 comprises equipment (by bracing or strutting arrangement) 2, four bracing or strutting arrangements 3.
Equipment 2 comprises base station 21, maintaining part 22, processing department 23, column sections 24, control part 25, protuberance 26.Base station 21 has four legs 211, and each leg 211 has the through hole 212 of above-below direction.The inner peripheral surface of through hole 212 is formed with negative thread (not shown).
Protuberance 26 has outstanding post portion 261 integratedly and inserts protuberance 262.
Outstanding post portion 261 is in cylindric, and its side face is formed with pin thread (not shown).Outstanding post portion 261 screws togather with the through hole 212 of the leg 211 of base station 21.The side, bottom in outstanding post portion 261 is given prominence to downward from leg 211.Insert protuberance 262 to give prominence to downward from the bottom in outstanding post portion 261, and in thinner than outstanding post portion 261 cylindric.
Column sections 24 is fixed on base station 21 top.Processing department 23 supports to and can move up and down by column sections 24.
Processing department 23 is positioned at the front side of column sections 24.Column sections 24 has tool storage room 230 in processing department 23 front portion.Tool storage room 230 is discoid in what can rotate in the circumferential.Multiple instrument 231 is installed on tool storage room 230 in the mode that can install and remove respectively.
Maintaining part 22 is located at base station 21 top, and is located on the downside of processing department 23.Maintaining part 22 is so-called workbench, and it keeps workpiece (not shown).Maintaining part 22 supports to and can move along direction, all around by base station 21.
Control part 25 is configured at the rear side of column sections 24.The moving up and down of control part 25 pairs of processing departments 23, the rotation of tool storage room 230, the movement of maintaining part 22 control.
Be positioned at tool storage room 230 instrument 231 bottom to process workpiece.An instrument in multiple instrument 231 is carried towards above-mentioned by rotating by tool storage room 230 bottom.Moved up and down by processing department 23 and instrument 231 rotates, processing implemented by instrument 231 pairs of workpiece.Maintaining part 22 moves along all around direction, to change the position of processing work.
Each bracing or strutting arrangement 3 is positioned at the bottom of equipment 2.Each leg 211 is located at by each bracing or strutting arrangement 3.Each bracing or strutting arrangement 3 comprises fixed part 31, sliding part 32.Sliding part 32 is integrally formed with movable insertion section 321 and protuberance bearing 322.Movable insertion section 321 is in the form of annular discs.The lower surface 32a of movable insertion section 321 is rounded plane.At the projecting protuberance bearing 322 having mountain peak shape upward of movable insertion section 321 upper surface.The top of protuberance bearing 322 has inserts recess 33.Insert recess 33 opening upward.The horizontal cross-section of inserting recess 33 is circular.The diameter of this circle inserting recess 33 is roughly the same with the external diameter of the insertion protuberance 262 of protuberance 26.
The insertion protuberance 262 (cephalic par namely on the downside of protuberance 26) of protuberance 26 is inserted in the mode that can insert or deviate from and inserts recess 33.When insertion protuberance 262 being inserted into insertion recess 33, protuberance 26 is not combined with sliding part 32.But protuberance 26 can not relative to sliding part 32 relatively transverse shifting.
Fixed part 31 is in thicker than the movable insertion section 321 of sliding part 32 discoid in vertical.The lower face side of fixed part 31 is configured at the floor F of factory.The upper surface of fixed part 31 is provided with recess 41.
Recess 41 opening upward, it is inner in cylindric.The internal diameter of recess 41 is larger than the external diameter of the movable insertion section 321 of sliding part 32.The thickness of the movable insertion section 321 of the depth ratio sliding part 32 of recess 41 is little.The inner bottom surface 41a of recess 41 is broader than the lower surface 32a of sliding part 32 and is in the circular plan shape of horizontal posture.Inner bottom surface 41a and the inner peripheral surface 41b of recess 41 are orthogonal.
Recess 41 is inserted in the movable insertion section 321 of sliding part 32.The lower surface 32a of sliding part 32 contacts with the inner bottom surface 41a of recess 41 in slidable mode.Therefore, sliding part 32 can relative to fixed part 31 relatively transverse shifting.In other words, the base station 21 of equipment 2 can relative to floor F relatively transverse shifting.
Therefore, the difference between the external diameter of the internal diameter of recess 41 and the movable insertion section 321 of sliding part 32 is configured to enough little value (such as below 1mm).
Such as, when in factory, change configures, if operator uses lowering or hoisting gear to make equipment 2 move upward, then the insertion protuberance 262 of each protuberance 26 can easily be extracted from the insertion recess 33 of each bracing or strutting arrangement 3.Afterwards, equipment 2 is carried to assigned position by operator.
If operator makes equipment 2 move downward above each bracing or strutting arrangement 3, then the insertion protuberance 262 of protuberance 26 easily can insert the insertion recess 33 of each bracing or strutting arrangement 3.Now, bracing or strutting arrangement 3 because of the deadweight of equipment 2 stably support works device 2.
Each protuberance 26 can adjust from the overhang that leg 211 is outstanding.This overhang is changed by the position of changing protuberance 26 and the through hole 212 of leg 211 and screwing togather.By adjusting this overhang, the distance that each leg 211 leaves floor F changes, and base station 21 can maintain flat-hand position.
Below the difference of lathe 1 with existing lathe is described.
Existing lathe 100 shown in Fig. 5 comprises equipment 2, four bracing or strutting arrangements 300.
Each bracing or strutting arrangement 300 is provided with at an upper portion thereof and inserts recess 33, and the bottom of each bracing or strutting arrangement 300 is configured at floor F.Bracing or strutting arrangement 300 is integrally formed, and does not have fixed part 31 and the sliding part 32 of bracing or strutting arrangement 3 of the present utility model.Therefore, the protuberance 26 of equipment 2 or even base station 21 can not relative to floor F relatively transverse shiftings.
When the maintaining part 22 of equipment 2 carries out transverse shifting, inertia force during acceleration and deceleration can cause maintaining part 22 to be vibrated in the horizontal.The workpiece particularly kept in maintaining part 22 is heavier, or maintaining part 22 high-speed mobile, or in the situation such as maintaining part 22 conversion direction, easily produces the vibration of maintaining part 22.
Such as high-speed mobile forward maintaining part 22 to the right sharply conversion direction time, maintaining part 22, towards moving right, is vibrated on one side in the longitudinal direction.Existing lathe 100, when making the Work piece high-speed conversion direction of such as 100kg, can produce the vibration of 50Hz ~ 60Hz.The eigentone of this vibration and maintaining part 22 is roughly equal.Particularly after direction is just changed, the vibration of maintaining part 22 has the comparatively large amplitude of about 0.015mm.
The vibration of maintaining part 22 is understood process in time and decays.In vibration processes, maintaining part 22 can produce dislocation relative to processing department 23 (specifically instrument 231) on direction of vibration, and therefore, machining accuracy can be deteriorated.Therefore, the vibration suppressing maintaining part 22 is needed.
Because base station 21 supports maintaining part 22, therefore the vibrational energy of maintaining part 22 can be passed to base station 21.
Therefore, in lathe 1, along with the vibration of maintaining part 22, base station 21 also vibrates.But base station 21 is difficult compared with maintaining part 22 to be vibrated, and the vibration of base station 21 easily decays.This is because base station 21 is heavier than maintaining part 22 because supporting maintaining part 22.Along with the vibration of base station 21, the lower surface 32a of sliding part 32 slides on the inner bottom surface 41a of recess 41.Larger frictional resistance is produced between the lower surface 32a and the inner bottom surface 41a of recess 41 of sliding part 32.Therefore, the vibrational energy being passed to base station 21 reduces fast.
The vibrational energy of maintaining part 22 is consumed in the outside of maintaining part 22, and therefore, the vibrational energy of maintaining part 22 reduces fast.That is, the vibration rapid decay of maintaining part 22.Because base station 21 also vibrates together with maintaining part 22 simultaneously, therefore the vibration frequency of maintaining part 22 is no longer consistent with the eigentone of maintaining part 22.Therefore, the vibration amplitude of maintaining part 22 less than existing lathe 100 (being such as about 0.008mm).
The base station 21 of existing lathe 100 is fixed on floor F by bracing or strutting arrangement 300, and therefore, the vibrational energy of maintaining part 22 can not be consumed in the outside of maintaining part 22.
The lower surface 32a of the sliding part 32 of present embodiment and the inner bottom surface 41a of recess 41 is circle.Therefore, compared with when being rectangle with the lower surface 32a of such as sliding part 32, the impact when junction section between the inner bottom surface 41a of the junction section between the lower surface 32a of sliding part 32 and outer peripheral face and recess 41 and inner peripheral surface 41b abuts along with the vibration of sliding part 32 is less.This is because the collision in such bight, four angles that there is not rectangle.
As mentioned above, the vibration of lathe 1 maintaining part 22 that bracing or strutting arrangement 3 can be utilized to suppress to produce during processing work.Bracing or strutting arrangement 3 to the suppression of vibration based on be frictional resistance, instead of based on the viscous drag of viscous fluid.That is, lathe 1 can suppress the vibration of maintaining part 22 when not using viscous fluid.Therefore, can eliminate as suppressing vibration to use the various undesirable situation (attachment of foreign matter, the variation etc. of transaction capabilities) produced during viscous fluid.
When using viscous fluid, viscous fluid is filled in the inside of recess 41.The frictional resistance produced between the lower surface 32a and the inner bottom surface 41a of recess 41 of sliding part 32 reduces because of the existence of viscous fluid, may hinder the suppression of the vibration to maintaining part 22.

The circular plate of sliding component 323 in horizontal posture, its upper surface is installed on the lower surface of movable insertion section 321.The lower surface 32b of sliding component 323 is the circular plan shape of horizontal posture.The degree of depth of the Thickness Ratio recess 41 of sliding component 323 is little.
The lower surface 32b of sliding component 323 has the area with the lower surface of movable insertion section 321 (i.e. the lower surface 32a of embodiment 1) same degree.But lower surface 32b is at least large than the frictional resistance of the lower surface 32a of embodiment 1 relative to the frictional resistance of the inner bottom surface 41a of recess 41.
Movable insertion section 321 and the sliding component 323 of sliding part 32 insert recess 41.The lower surface 32b of sliding part 32 contacts with the inner bottom surface 41a of recess 41 in slidable mode.The same with the sliding part 32 of embodiment 1, the sliding part 32 of embodiment 2 also can relative to fixed part 31 relatively transverse shifting.But the frictional resistance of lower surface 32b is larger than the frictional resistance of the lower surface 32a of embodiment 1, and therefore, the vibration of maintaining part 22 decays more rapidly.
When fixed part 31 and sliding part 32 are such as made of metal, in the lathe 1 of embodiment 1, noise may be produced because the lower surface 32a of sliding part 32 slides relative to the inner bottom surface 41a of recess 41.When sliding component 323 is such as made up of synthetic rubber, the lathe 1 of embodiment 2 can reduce the noise produced because of slip.
