Description
Technical field
The utility model relates to machinery fields, and in particular to a kind of universal straight line slide unit.
Background technique
Straight line slide unit be it is a kind of can provide linear motion mechanical structure, can either in a horizontal or vertical use, can also combine
It is used at specific movement mechanism, currently, straight line slide unit mainly uses following two form: first is that with the ball wire of precision drive
Bar slide unit, by stepper motor drive lead screw rotation, gap is embedded with steel ball between screw rod and sliding block, so as to by them it
Between sliding friction become rolling friction, to substantially reduce frictional force between the two, the rotary motion of motor is converted
For the linear motion of slide unit；Second is that using the rack-and-pinion slide unit mould group of gear and rack teeth mechanism, motor driven gear rotation, rack gear
It is fixed on bottom plate, rack and pinion engagement movement, since rack gear is fixed so gear while doing linear translational motion and rotation
Movement, but both the above mode has the following problems: ball leading screw driving is to be widely used in industrial automation in method one
The basic transmission device of equipment, but use cost is higher；The kind of drive of two middle gear rack gear of mode is rigidly good, and load is big, the longevity
Life length, movement controllability is good, higher to the requirement on machining accuracy of components, and heavy equipment is suitble to select.
And toothed belt transmission flexibility ratio is high, has unique advantage particularly with the occasion of narrow space, has at present not
Few producer drives slide unit movement using synchronous pulley and synchronous belt, drives and is fixed on synchronous belt when synchronous pulley rotates
Slide unit moves in a straight line, but toothed belt transmission needs to pre-tighten and is all that manual pre-tighten greatly reduces working efficiency, and due to
The service life for substantially reducing belt not in time is pre-tightened, use cost is increased.
Utility model content
The purpose of this utility model is to provide a kind of transmission to stablize, load is big, sliding is smooth and can pre-tighten automatically logical
With type straight line slide unit.
For this purpose, the utility model uses following technical scheme:
