Description
Technical field
The utility model belongs to the machine tool accessory technical field, relates to a kind of lathe foot pad.
Background technique
Lathe comprises the lathe pin, and the lathe pin is fixed on the bottom of lathe, for contacting with ground, makes the stable placement of lathe on the ground.Generally all need to guarantee the horizontal accuracy of its main lathe bed but be placed on ground lathe, this just need to be adjusted the height of lathe pin; And lathe adding man-hour, generally all there are larger vibrations, vibrations can reduce the machining accuracy of lathe too strongly.
For above-mentioned be problem, people design some height-adjustable, and the lathe foot pad that also there is shock-absorbing function, be arranged at the bottom of lathe pin, for example the Chinese patent literature data discloses high damping Automatic Levelling vibration damper [application number 91213831.9], it is the supporting feet of machine tool, by base and elevator mechanism, formed, elevator mechanism is comprised of bolt and square nut, the bottom of base connects a rubber pad, the space of an indent is arranged at the bottom of rubber pad, the front end of bolt end face spherical in shape, square nut is positioned at the square groove on base top, the middle of bottom land is recessed into conical surface downwards, bolt is connected with screw thread with square nut, its front end spherical end surface stretches out screw and contacts with conical surface.
The supporting feet of this kind of structure, bolt is connected with screw thread with square nut through the footing hole of lathe, by swivel bolt, makes the square nut lifting reach suitable height, thereby adjusts the height of lathe and the levelness of lathe; But the supporting feet of this kind of structure can only be positioned over height and the levelness that could adjust accurately lathe on very smooth ground, once ground is smooth not, error during adjusting is just larger, be difficult for level-off, and due to bolt for the rotating part that connects the instrument such as spanner the inside at the lathe pin, swivel bolt comparatively bothers, and regulates trouble.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, and a kind of lathe foot pad simple, that degree of regulation is high of regulating is provided.
The purpose of this utility model can realize by following technical proposal: a kind of lathe foot pad, comprise base, it is characterized in that, it also comprises a ball stud, the center of described base upper surface has concave spherical surface, one end of described ball stud is for having externally threaded joint one, and the other end is that the joint two and the described joint two that with concave spherical surface, are complementary are positioned at above-mentioned concave spherical surface place, between described joint one and joint two, has the pulling part for being connected with instrument.
Joint one and the lathe pin screw thread of ball stud are connected, the joint two of ball stud and the concave spherical surface face of base contact and are rotationally connected, even Installing machine tool is on irregular ground, base is low dip slightly, by the joint two of ball stud and the concave spherical surface of base, match, can make ball stud vertically, thereby improve the levelness that lathe master lathe bed is installed, degree of regulation is high, and joint two and concave spherical surface cooperatively interact and can also adjust the skew of the substantially horizontal that lathe causes in use for some time; The machine bed leg pad is clamped pulling part roating sphere hook bolt by spanner, and pulling part is regular hexagon, makes the ball stud precession or screws out the lathe pin, carrys out the levelness of height and the lathe master lathe bed of adjusting tool, regulates simply, and degree of regulation is high.
In above-mentioned a kind of lathe foot pad, the center of described joint two bottoms has interior threaded hole, the center of described base lower surface has the rounded groove of cross section, have through hole between described groove and described concave spherical surface, and the diameter of through hole is less than the radial length of groove.The cross section of groove is rounded, and the diameter of groove is greater than the diameter of through hole, and certainly the cross section of groove also can be square or rectangular, as long as minor face still is greater than the diameter of through hole.
In above-mentioned a kind of lathe foot pad, in described through hole, activity is equipped with connecting bolt, one end of described connecting bolt is connected in by screw thread in the interior threaded hole of joint two, and the diameter of the described connecting bolt the other end is greater than the diameter of through hole and is less than the radial length of groove.Connecting bolt makes ball stud be connected with base, and lathe base in handling process also can not come off, and between connecting bolt and base, is to be flexibly connected, and the rotation of ball stud is unaffected.
In above-mentioned a kind of lathe foot pad, between the other end of described connecting bolt and bottom portion of groove, there is gap.When base is placed on irregular ground, the longitudinal center line of ball stud and the longitudinal center line of the base angle that can stagger, this gap makes ball stud can slightly rotate certain angle.
In above-mentioned a kind of lathe foot pad, the described ball stud joint one place locking nut that has been threaded.After lathe height, Level-adjusting are good, locking nut rotates on the lower surface that abuts against the lathe pin upward, and ball stud is fixed, and ball stud can not rotate because of the vibrations of lathe, and the firm degree that ball stud is connected is high, the lathe good stability.
In above-mentioned a kind of lathe foot pad, the lower surface of described base has an annular mounting hole, in described mounting hole, is fixed with snubber block, and the bottom of described snubber block protrudes from the lower surface of base.Snubber block ringwise, is connected in the mounting hole of base, and the lower surface of snubber block directly contacts with ground, and snubber block absorbs the vibrations that lathe produces when work, reduces the vibrations of lathe, makes the lathe good stability, improves the machining accuracy of lathe.
In above-mentioned a kind of lathe foot pad, also there is pad in described mounting hole, a side of described pad is close to the upper surface of snubber block, and opposite side is close on base.Pad increases the lifting surface area of snubber block, thereby improves the damping effect of lathe foot pad.
In above-mentioned a kind of lathe foot pad, described snubber block is made by polyurethane material.Snubber block is once injection molded by polyurethane material, and more than hardness reaches 90 degree, load-bearing property is good, and shock-absorbing effect is good.
Compared with prior art, the lathe foot pad that the utility model provides has the following advantages:
1, the pulling part on the machine bed leg pad ball stud is positioned at lathe underfooting side, pulling part by instrument rotating ballhead bolts such as spanners makes joint one precession of ball stud or screws out the lathe pin, carry out the levelness of height and the main lathe bed of adjusting tool, regulate simple; And joint two spherical in shape and the concave spherical surface of base match by ball stud, even Installing machine tool also can guarantee ball stud vertically, thereby improve the degree of regulation of lathe height and levelness not being on very smooth ground.
2, the bottom of the machine bed leg pad is fixed with an annular snubber block injection molded by polyurethane material, and load bearing effect is good, and shock-absorbing effect is good, has increased the using scope of lathe foot pad, the lathe good stability.
3, the machine bed leg pad, by locking nut lock ball hook bolt, fixes ball stud, and ball stud can not rotate because of the vibrations of lathe, and the firm degree that ball stud is connected is high, the lathe good stability.
