Description
Technical field：
The utility model is related to machine tool drive leading screw protection technology fields, and in particular to a kind of wound form machine tool drive leading screw
Protective device.
Background technology：
Ball screw assembly, is as the driving parts of other pivoting frictions, as long as avoiding abrasive particle and chemically reactive substance
Into, so that it may to think that these elements are almost to work in the case where not generating abrasion, but such as fallen on raceway dirty
Object, or using dirty lubricating oil, the proper motion of ball can be not only interfered, but also abrasion is made to sharply increase, manufacture is missed
For the ball-screw-transmission pair of poor and preload deflection in microns, this abrasion is just especially sensitive, therefore effectively protect,
Sealing and the cleaning of holding lubricating oil just seem very necessary.
Generally use felt circle is sealed nut, and felt circle thickness is 2 ~ 3 times of screw pitch, and endoporus makes spiral shell
The shape of line is allowed to closely encase leading screw, and puts into nut or the slot really of sleeve two, and sealing ring is in addition to using softness
Outside the Numeric Control Technology of felt, oil-proof rubber or nylon material can also be used, since sealing ring and leading screw are in direct contact, sealing effect
Fruit is bad, while also increasing the frictional resistance moment of ball screw assembly,.
Utility model content：
The purpose of the utility model is to overcome existing leading screw sealing structure sealing effect is bad, the big problem of frictional resistance,
A kind of reduction frictional resistance is provided, sealing effect, the wound form machine tool drive leading screw protecting device cleared up automatically are improved.
Above-mentioned purpose is realized by following technical scheme：
A kind of wound form machine tool drive leading screw protecting device, composition include：Guard shield, interior point of the guard shield
Ball nut, supporting mechanism and strainer are not installed, the ball nut is connect with leading screw, the both ends of the leading screw
It is located at outside the guard shield across the side of the guard shield, the supporting mechanism and the strainer
Between be provided with steel band, the both ends of the steel band are respectively wound around on the leading screw to be fixedly connected with the leading screw.
The wound form machine tool drive leading screw protecting device, the protection shell both sides are provided with cleaning shell, institute
The cleaning casing stated is connect on the leading screw with the protection outer casing screw.
The wound form machine tool drive leading screw protecting device, the supporting mechanism includes two support rollers, described
Support roller pass through with the protection enclosure and support axis connection.
The wound form machine tool drive leading screw protecting device, the strainer includes tensioning plate, the tensioning
Plate, by fixing axis connection, the first fixed pin, the guarantor is provided on the tensioning plate with the protection enclosure
Shield enclosure interior is provided with the second fixed pin, is connected by spring between first fixed pin and second fixed pin
It connects, axis pin there are two fixations on the tensioning plate, tensioning wheel is installed on the axis pin.
The wound form machine tool drive leading screw protecting device, the screw pitch of the leading screw are equal to the width of the steel band
Degree, the depth of the thread groove of the leading screw are equal to the thickness of the steel band.
Advantageous effect：
1. the operation principle of the utility model is：The both ends of steel band are separately fixed on leading screw.Steel band bypasses support roller,
And by spring and tensioning wheel by steel belt tensioning, when leading screw rotates, the steel band of leading screw one end is released by the screw pitch of leading screw, and another
One end then with same screw pitch by steel band spooling on leading screw, since the width of steel band is just the screw pitch of leading screw, spiral shell
Groove is firmly blocked thereon, and since the obverse and reverse sides of steel band do not contact always, the foul of steel band outer surface adherency would not be by band
Onto inner surface, inner surface is made to keep cleaning.
The utility model setting cleaning shell so that the sundries or dirty lubricating oil being sticked on steel band can be cleaned outer
The arc plate of shell lower part is wiped off, can further be cleared up steel band, can be kept the cleaning of steel strip surface, prevents steel band from winding
Leading screw operation is had an impact when on to leading screw.
Strainer is arranged in the utility model, steel band can be made to be constantly in tensioning state, prevents from loosening due to steel band
Cause leading screw operation impacted.
Support device is arranged in the utility model, can play the role of support to steel band, realizes steel band one ends wound in silk
On thick stick, the other end is wrapped in the steel band on leading screw and is released, and realizes that the relieving of steel band is run simultaneously with winding.
