Abstract
The utility model relates to an automatic leveling vibration reducing device, which is composed of a base, a steel ball, a lifting seat, a rubber pad and a secondary vibration reducing seat. The secondary vibration reducing seat and the lifting seat form a spherical pair. The secondary vibration reducing seat is provided with a rubber block. As the utility model adopts the spherical pair structure and a primary vibration reducing device is additionally provided, the utility model overcomes the drawbacks of the existing vibration reducing device that the multipoint leveling is time-consuming with large labor consumption, and the bottom face of a machine tool is damaged. The utility model not only has easy leveling, but also has good stability. After the machine tool is leveled, the leveling accuracy of the original machine tool can not be damaged by the larger external force when the machine tool works.
Description
The utility model automatically levelling vibration damping equipment is a kind of yielding support.It is mainly used in installation, debugging, maintenance, the maintenance of machine tool, also can be used for levelness and shockproof device of having relatively high expectations, as: refrigerator, big power washing machine, Haug drainer etc.
Yielding support is a kind of comparatively advanced supporting.At present, adopt this supporting that the more and more of lathe are installed both at home and abroad, the trend that replaces traditional rigid support is arranged greatly.Present yielding support generally is made up of rubber pad, base, steel ball and elevating bracket, the fixing bolt in addition that has.This supporting has that vibration damping is moving, shock insulation, noise reduction, simplification are installed, easy to adjust, carrying flexibly and improve advantage such as machining accuracy.It has compared remarkable progress with rigid support.But we find that it also has the some shortcomings part in practice and after the serious analysis.The smoothing of this supporting realizes by the rotation and lifting seat fully.Because being installed, a machine tool to use several supportings, one by one still comparatively time-consuming, the effort of these supportings of adjustment.Moreover elevating bracket and lathe face contact friction force are big, and during adjustment, elevating bracket rotates and can scratch the lathe bottom surface, lathe is rotated or displacement, add to the difficulties to smoothing, therefore its are done further to improve that to improve is necessary.
The purpose of this utility model is a kind of laborsaving, automatically levelling vibration damping equipment of saving time, not hindering lathe of design.
The utility model automatically levelling vibration damping equipment has base; steel ball; elevating bracket; rubber pad; the secondary vibration proof mounting is arranged on the elevating bracket; elevating bracket and secondary vibration proof mounting constitute spherical pair; on the secondary vibration proof mounting block rubber is arranged; the secondary vibration proof mounting is higher than on the elevating bracket groove dark that constitutes spherical pair with the secondary vibration proof mounting; spherical pair this structure is the characteristics of having utilized ball to roll (are stressed after unstability); make lathe through after the preset; rely on own wt pressure automatically levelling; spherical pair has three degree of freedom and plays a part universal levelling; make that the adjustment machine tool horizontal is easier; simultaneously; because the frictional force that its frictional force contacts with block rubber less than the lathe bottom surface; so the torsion digestion during the elevating bracket rotation is in spherical pair; can not cause scratching the lathe bottom surface and lathe is rotated; and the destruction horizontal accuracy; be reflected in just moving up and down on the lathe bottom surface; be convenient to preliminary adjustment; block rubber on the secondary vibration proof mounting is the one-level vibration damping equipment that the utility model increases, and effectiveness in vibration suppression is further improved.
Automatically levelling vibration damping equipment of the present utility model, there is a through hole at secondary vibration proof mounting middle part, concentric with the bolt hole on the elevating bracket, but diameter is greater than the bolt hole on the elevating bracket, on the secondary vibration proof mounting through hole being set, is in order to install and fix bolt, so that the utility model is used to have the lathe in lower margin hole, the diameter of through hole is for when the utility model is loaded onto fixing bolt greater than the bolt hole on the elevating bracket, also can automatically levelling.
The utility model is owing to be provided with the secondary vibration damping equipment, and makes it and elevating bracket constitutes spherical pair, makes vibration damping equipment have the automatically levelling and the further function of vibration damping, improved the smoothing precision, shortened collating time, reached save time, the labour-saving purpose.This device stability is good.After the smoothing, lathe is subjected to bigger external force effect when work can not destroy original machine tool horizontal precision yet.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
Fig. 1 automatically levelling damping device structure schematic representation (being used to have the lathe in lower margin hole) is screw 1., 2. tray, 3. rubber pad, 4. steel ball, 5. base, 6. elevating bracket, 7. secondary vibration proof mounting, 8. block rubber, 9. bolt
The utility model is made up of screw 1, tray 2, rubber pad 3, steel ball 4, base 5, elevating bracket 6, secondary vibration proof mounting 7, block rubber 8 and bolt 9.3 one-level damping effects of 12 rubber pads are arranged below the base 5, steel ball 4 is connected on the elevating bracket 6 by 4 screws 1 of tray 2 usefulness, can freely roll, steel ball partly exposes, secondary vibration proof mounting 7 is positioned on the elevating bracket 6, constitute spherical pair with elevating bracket 6, block rubber 8 is placed in and plays the secondary damping effect on the secondary vibration proof mounting 7, secondary vibration proof mounting 7 middle parts have a through hole concentric with the bolt hole on the elevating bracket 6, but diameter is greater than the bolt hole on the elevating bracket 6, bolt 9 passes secondary vibration proof mounting 7 and is threaded with elevating bracket 6, base 5 is threaded with elevating bracket 6 for basic part, has just constituted this device, elevating bracket 6 on the base 5 can more than revolve, backspin is adjusted levelness, elevating bracket 6 makes the steel ball kiss the earth to backspin, removable lathe.During use the bolt on the vibration damping equipment being penetrated in the lathe lower margin hole band upper gasket and nut screws with spanner and gets final product.
Claims (2)
1, a kind of automatically levelling vibration damping equipment has base, steel ball, elevating bracket, rubber pad, and it is characterized in that has the secondary vibration proof mounting on the elevating bracket, and elevating bracket and secondary vibration proof mounting constitute spherical pair, on two utmost point vibration proof mountings block rubber are arranged.
