Abstract
The invention discloses a machine tool antiskid protecting device and relates to the technical field of machinery manufacturing. The machine tool antiskid protecting device comprises a vertical screw mounted in a vertical screw holder. A friction plate and a movable ring are sleeved on an extension part, extending out of the vertical screw holder, of the vertical screw. A star wheel is disposed between the upper section of the movable ring and the vertical screw. An axial thrust ball bearing is disposed between the lower section of the movable ring and the vertical screw. A disc-shaped spring is pressed to an end face of the thrust ball bearing. An adjusting pad is disposed on the other end face of the disc-shaped spring. The adjusting pad is connected with the disc-shaped spring in a compacted manner through a locking nut sleeved on tip threads of the extension part of the vertical screw. By the machine tool antiskid protecting device, the problems that milling and boring machine tool vertical parts slides down during mechanical balance failure and motor brake failure to cause operator injury, machine tool precision damage, cutter damage, workpiece surface scratches, economical loss and the like are solved.
Description
Technical field
The present invention relates to plant equipment manufacturing technology field, especially a kind of in, the large-sized numerical control milling-boring machine is vertical uses anti-skidding protection mechanism.
Background technology
Present domestic manufacturing, sale and use be numerical control milling-boring machine or the supporting vertical Lift Part of machining center, have following defective: 1, have only vertical lifting motor dead electricity band-type brake, lifting motor dead electricity band-type brake after losing efficacy vertical parts were glided because of gravity; 2, have only vertical mechanical type counterweight balance, after the chain of weight or the steel wire rope fatigue fracture, vertical parts glide because of gravity; 3, have only the hydraulic accumulator balance, glide because of gravity because the inefficacy of accumulator balance or pipeline leak produce vertical parts.The existence of these defectives can make the vertical parts of milling-boring machine down cause operating personnel injured during landing in accident, and machine tool accuracy is impaired, and cutter is destroyed, and surface of the work such as is bruised at accident, causes unnecessary economic loss.
Summary of the invention
Problem to be solved by this invention provides the anti-skidding protective device of a kind of lathe; it can solve after the vertical parts of milling-boring machine damage to lose efficacy because of mechanical balance or the motor band-type brake lost efficacy; because of gravity down landing may cause operating personnel injured; machine tool accuracy is impaired; destroyed and the surface of the work of cutter is bruised etc., causes the problem of economic loss.
In order to address the above problem, technical scheme of the present invention is: the anti-skidding protective device of this lathe comprises the vertical screw mandrel that is contained in the vertical screw rodb base; The extension that described vertical screw mandrel stretches out described vertical screw rodb base is set with wearing piece and moving-coil successively; Be provided with star-wheel between described moving-coil epimere and the described vertical screw mandrel, be provided with axial ball bearing between described moving-coil hypomere and the described vertical screw mandrel; Described axial ball bearing end face is crimped with disk spring, and described disk spring other end is provided with adjusting pad, and described adjusting pad compresses with described disk spring and is connected by being enclosed within locking nut on the screw thread of described vertical screw mandrel extension termination.
In technique scheme, more specifically scheme can be: the described described star-wheel of described vertical screw mandrel that is enclosed within is by flat key and described vertical screw mandrel interlock; Be provided with the fore-set that connects spring in the described star-wheel, described fore-set withstands the roller that is located between described star-wheel and the described moving-coil.
Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:
When the gravity that produces when 1, the vertical parts of milling-boring machine of the present invention glide drives vertical screw mandrel rotation, just overcome the vertical screw mandrel of prevention with mechanical adjustable anti-skidding institutional adjustment to frictional force and rotate and reach the purpose that vertical mechanism does not glide.
2, solve because the vertical parts of milling-boring machine damage because of mechanical balance lost efficacy, the motor band-type brake lost efficacy because of gravity down landing may cause operating personnel injured, machine tool accuracy is impaired, cutter is destroyed, surface of the work is bruised etc., causes the function of economic loss,
3, described anti-skidding mechanism can use at multiple Digit Control Machine Tool.
4, can improve the reliability of lathe, good cost performance.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is A-A cutaway view among Fig. 1.
Number in the figure is represented: 1, wearing piece; 2, star-wheel; 3, axial ball bearing; 4, moving-coil; 5, disk spring; 6, adjusting pad; 7, locking nut; 8, flat key; 9, vertical screw mandrel; 10, spring; 11, fore-set; 12, roller; 13, vertical screw rodb base.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
The anti-skidding protective device of the lathe of Fig. 1 and Fig. 2 comprises the vertical screw mandrel 9 that is contained in the vertical screw rodb base 13, and the extension that vertical screw mandrel 9 stretches out vertical screw rodb base 13 is set with wearing piece 1 and moving-coil 4 successively; Be provided with star-wheel between moving-coil 4 epimeres and the vertical screw mandrel 9, star-wheel 2 is enclosed within on the vertical screw mandrel 9, by flat key 8 and vertical screw mandrel 9 interlocks; Be provided with the fore-set 11 that connects spring 10 in star-wheel 2, fore-set 11 withstands the roller 12 that is located between star-wheel 2 and the moving-coil 4.Be provided with the axial ball bearing 3 that is enclosed within on the vertical screw mandrel 9 between moving-coil 4 hypomeres and the vertical screw mandrel 9; Axial ball bearing 3 end faces are crimped with disk spring 5, and disk spring 5 other ends are provided with adjusting pad 6, and adjusting pad 6 compresses with disk spring 5 and is connected by being enclosed within locking nut 7 on the vertical screw mandrel 9 extension termination screw threads.
Operation principle of the present invention is: when the vertical parts of boring and milling machine lost efficacy because of accident, because driving vertical screw mandrel 9, gravity is rotated counterclockwise, as scheme A-A cut open the institute look, spring 10 pushes away fore-set 11 makes roller 12 toward the little spatial movement of star-wheel 2, increase star-wheel 2, frictional force between roller 12 and the moving-coil 4, vertical screw mandrel 9 drives moving-coil 4 and is rotated counterclockwise, and moving-coil 4 produces the friction motion with wearing piece 1; By adjusting 7 pairs of adjusting pads 6 of locking nut, the thrust of disk spring 5 and axial ball bearing 3, thereby the friction of adjustment moving-coil 4 and wearing piece 1 reach the purpose that overcomes vertical parts downslide; Avoid the vertical parts of milling-boring machine down to cause operating personnel injured during landing in accident, machine tool accuracy is impaired, and cutter is destroyed, and surface of the work such as is bruised at accident, thereby avoids unnecessary economic loss.
