Description

The combined multipurpose parallels

The utility model relates to a kind of especially parallels of using of lathe of machinery of installing.

Existing parallels, as application number 89218726.3 " lathe Filled Iron for Vibration Damping ", application number is 92212300.4 " two-stage vibrationproof parallels ", its shortcoming: the one, the supporting surface of parallels can not carry out the rotation of Vertical direction, with the levelness of adjusting parallels, thereby can't realize that parallels firmly contacts with the lathe bed large size; The 2nd, damping element and parallels combine together, can only realize that lathe bed contacts with fixedly vibration damping (elasticity) between parallels, ground, and can not rigidity with select arbitrarily during in various degree vibration damping (elasticity) contacts and adjust; The 3rd, it is single to install and use mode, and parallels is held on the ground, and its underpart is not imbedded in the ground, make contact between parallels and ground insecure, reliable; The 4th, complex structure, manufacturing expense height.

The purpose of this utility model just provides a kind of lathe bed supporting surface levelness of parallels and adjusts automatically, can select and regulate the rigidity of parallels and vibration damping (elasticity) degree arbitrarily, mounting type is various, of many uses, be fit to various machine tools and use, contact good, firm combined multipurpose parallels.

For achieving the above object, the technical solution adopted in the utility model is: constitute the combined multipurpose parallels by center bolt, set screw nut, base etc., its structural feature is, base is " protruding " font, its outer surface of upper and adjusting element inner cavity surface scyewed joint, the top of adjusting element is passed bolt hole on the lathe bed pedestal for the upper end of the concave spherical surface that matches with ball ring, center bolt and is threaded with set screw nut, the middle part sky is enclosed within the inner chamber of ball ring, and the bottom is provided with to match with set screw nut and is used to install the securing means of parallels.

After adopting design as above, the ball ring that directly contact with lathe bed can vertically suitably rotation in the concave spherical surface of the adjusting element that matches with it, thereby adjusts the levelness of parallels automatically, and the realization parallels contacts with the good rigidity of the large size between lathe bed; Between ball ring and lathe bed, and set up different rigidity between base and the ground or resilient pad (backing plate) both can be regulated the parallels height easily, can select the rigidity or vibration damping (elasticity) degree of parallels again arbitrarily.Select center bolt and all the other part combinations in addition for use with different securing meanss, the activity between parallels and ground that then can realize is placed, bury underground fixing, the fixing several different installation of boring swelling, be applicable to interim installation and the inconvenient lathe of ground, the lathe that needs the fixed installation use, the various machine tools of quick fastening installation buried underground respectively, of many uses, easy to use.

Below in conjunction with the drawings and specific embodiments the utility model is done to describe in further detail.

Fig. 1 is vertical sectional structure schematic representation of the utility model embodiment one.

Fig. 2 is A-A sectional view of Fig. 1.

Fig. 3 is vertical sectional structure schematic representation of the utility model embodiment two.

Fig. 4 is vertical sectional structure schematic representation of the utility model embodiment three.

Fig. 5 is B-B sectional view of Fig. 4.

Fig. 1, Fig. 2 illustrate, the utility model embodiment one constitutes base 4 vertical profiles by center bolt 1, set screw nut 8, base 4 etc. and is " protruding " font, its outer surface of upper is threaded with adjusting element 5 inner cavity surface, the concave spherical surface of the top of adjusting element 5 for matching with ball ring 6, center bolt 1 upper end is passed the bolt hole on lathe bed 13 pedestals and is threaded with set screw nut 8, center bolt 1 middle part sky is enclosed within on the inner chamber of ball ring 6, and center bolt 1 underpart evagination is also closely chimeric with ball ring lower lumen concave surface.

Tighten set screw nut 8, both can realize that the lathe bed base of machinery such as lathe contacted with close and firm between parallels, base 4 upper support adjusting elements 5 and ball ring 6, then be held on the ground versatilely below, the screw thread that turns 4 of adjusting element 5 and bases is the height of each parallels of can regulate then, thereby regulate the horizontality of whole lathe, realize firmly, reliably install.Regulate for ease of installing, the outside of adjusting element 5 can be established one and is convenient to the hexagonal protrusions that wrench turns, and the cross-section, bottom of base 4 also is hexagon or polygon.The parallels of present embodiment is used for installing temporarily or be not easy to bury underground the installing and using of machinery equipment of ground.When interim the installation or under the less demanding situation, even can not need center bolt 1, set screw nut 8, directly will get final product down in lathe bed by the parallels pad that adjusting element 5, ball ring 6, base 4 are formed.

Also can set up pad 10 between ball ring 6 and lathe bed 13, this pad 10 has mesopore.Also sky is enclosed within on the center bolt 1, and pad 10 can so that do not dismantling under the other pieces situation, take out or insert center bolt 1 with pad 10 from the side at a side gap, and gap is not good for this pad certainly, and then contact is more firm.Change the thickness of pad 10, can adjust the height of parallels easily; Parallels and ground can be adjusted and select to the pad of selecting different materials to make then arbitrarily, in various degree rigidity or vibration damping (elasticity) contact between lathe bed.

Fig. 3 illustrates, and concrete formation of the utility model embodiment two, itself and embodiment's one difference is: center bolt 1 length is longer, the also empty mesopore that overregulates part 5, the mesopore of base 4 of covering in its middle part.The underpart of center bolt 1 is hook-shaped, is hooked on the anchoring piece 15 in the ground, cooperates with the set screw nut 8 of center bolt 1 upper end and forms the securing means that is used to install.The bottom of base 4 and center bolt 1 all lays fixed in the ground during installation.Tighten set screw nut 8, realize that promptly parallels contacts with fixation between lathe bed 13, ground.Be applicable to the installation that needs machinery equipments such as hard-wired various lathes.

Fig. 4, Fig. 5 illustrate concrete formation of the utility model embodiment three, and it is with embodiment two difference: the securing means of center bolt 1 bottom is different.Its securing means is center bolt 1 bottom overcoat one expansion sleeve 2, and sleeve pipe 2 tops are connected with base 4 inner chamber lower thread, and these sleeve pipe 2 bottoms have dilatation joint 16, and the outer surface indentation, and through Quenching Treatment.The root of center bolt 1 bottom is the taper that increases gradually downwards.Also can set up the ground backing plate 3 that is placed on the center bolt 1 in the bottom of base 4, this ground backing plate 3 also can be same by different rigidity or damping material system, select different ground backing plates 3 for use, also can select to adjust the rigidity and the damping property of parallels, also can adjust the length of parallels and center bolt.

During installation, center bolt 1 bottom and expansion sleeve 2 place in the ground datum hole, load onto all the other parts in addition, tighten the set screw nut 8 of center bolt 1 upper end, move on the tapered root of center bolt 1, the bottom of distending expansion sleeve 2, sawtooth on it is embedded in the ground, and it is tighter, very firm more to expand.This kind mode is suitable for the fastening lathe usefulness of quick mounting, can bear bigger vibration.
