Description
Technical field
The present invention relates to a kind of slide unit, especially a kind of slide unit based on worm screw tooth row.
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
Used at specific movement mechanism -- it is commonly referred to as XY axis, XYZ Zhou Deng poly-axial motion mechanism i.e. in automation industry.It is general next
It says, straight line slide unit can have drive part and slipper, and the drive part of traditional line slide unit is various, but these drive
Partially (transmission) in use, exposes different problems:
1, oil pressure elevating structure.The piston of oil cylinder can wear oil sealing after being used for a long time, and cause oil cylinder oil leakage phenomenon occur, carrying out
The problem of falling is easy to appear when vertical displacement movement, there are security risks.
2, feed screw nut's structure.Screw-nut structure is limited as transmission, impulse stroke by the length of lead screw,
It such as needs the movement of long stroke to transmit, then needs to configure longer lead screw, the cost is relatively high, and screw-nut structure conduct
When transmission realizes longitudinal movement, when drive motor is shut down, however it remains some potential safety problems.
3, hoist cable, wire rope structure.For this class formation in the case where being used for a long time and not overhauling, there are the wind of cables break
Danger.
4, gear tooth row structure.During the work time, only there are three the flank of tooth and teeth always on gear for gear tooth row transmission
Tooth on row contacts with each other, and in the moment started or stoped, transmission sound is larger, generates noise；And between gear and tooth row
Contact area it is minimum (actually therebetween be only line contact), on the one hand can generate stress concentration, lead to the entirety of slide unit
Load is severely limited, and on the other hand also affects the whole service life of slide unit.
Therefore a kind of method or apparatus for being able to solve the above problem is needed now.
Summary of the invention
The present invention is to propose a kind of simple in sturcture, ingenious in design, cloth to solve above-mentioned deficiency present in the prior art
Rationally, safety coefficient is high for office, loads the big slide unit based on worm screw tooth row.
The technical solution of the invention is as follows: a kind of slide unit based on worm screw tooth row, it is characterised in that: the slide unit packet
Rectilinear orbit fixing base 1 is included, wired rail 2 and tooth row 3 are set on rectilinear orbit fixing base 1, are provided on the tooth row 3 multiple equally distributed
Tooth 4, the slide unit further include sliding block fixing seat 5, and worm screw fixing seat 6, the worm screw are fixedly connected in the sliding block fixing seat 5
Rotational support has worm screw 7 in fixing seat 6, and the worm screw 7 matches with the tooth row 3, is additionally provided with and watches in worm screw fixing seat 6
Motor 8 is taken, the servo motor 8 is connected with the end of the worm screw 7 by pulley drive pair, is set in worm screw fixing seat 6
At least two support portions 9 are equipped with, the top of all support portions 9 is supported by mobile working platform 10, the worm screw fixing seat 6 jointly
Bottom end be provided with sliding block 11, the sliding block 11 is slidably connected on online rail 2.
The line rail 2 is two to be parallel to each other, and the tooth row 3 is between two lines rail 2.
The line rail 2 is one, and tooth row 3 is located at the top of line rail 2.
The present invention compared with the existing technology, has the advantages that
The slide unit based on worm screw tooth row of this kind of structure type, simple in sturcture, ingenious in design, rationally distributed, it is for tradition
The transmitting that slide unit is mostly moved using rack pinion pair, and by generation variety of problems, it is a kind of special to design
Slide unit structure, it creatively designs the tooth row that can be engaged with worm screw and just can send out with the tooth row when worm screw rotates
Raw relative motion, and then linear motion is converted by the output of the torque of motor.Compared with traditional rack-and-pinion type transmission mechanism,
At any time, worm screw can all be in contact this transmission mechanism with multiple teeth, i.e., there are a plurality of lines to contact between worm screw and tooth row,
And the quantity of contact line then depends on the quantity of helical tooth on worm screw, therefore designer can carry out the spiral number of teeth according to design requirement
The determination of amount, and then achieve the purpose that adjust contact line quantity.The quantity of contact line is more, and the afforded load of this slide unit is got over
Greatly, self-lock ability is stronger, so even there is motor shutdown, this kind of slide unit will not be fallen in vertical direction.
The sound issued in this slide unit operation process simultaneously is minimum, and the speed buffering for being able to achieve high torque rotation and heavy load is fixed
Position；The effective travel of this kind of slide unit, depending on the length of wherein tooth row, since the structure of tooth row is relatively easy, theoretically
Say that this slide unit can realize the stroke of random length.And the manufacture craft of this slide unit is simple, and manufacturing cost is cheap, therefore can
To say that it has a variety of advantages, particularly suitable for promoting and applying in the art, market prospects are very wide.

Specific embodiment
Below in conjunction with Detailed description of the invention a specific embodiment of the invention.As shown in Figures 1 to 4: one kind being based on worm tooth
The slide unit of row, it includes rectilinear orbit fixing base 1, and wired rail 2 and tooth row 3 are arranged on rectilinear orbit fixing base 1, is provided on the tooth row 3
Multiple equally distributed teeth 4, the slide unit further include sliding block fixing seat 5, and it is solid that worm screw is fixedly connected in the sliding block fixing seat 5
Reservation 6, rotational support has worm screw 7 in the worm screw fixing seat 6, and the worm screw 7 matches with the tooth row 3, fixes in worm screw
Servo motor 8 is additionally provided on seat 6, the servo motor 8 is connected by pulley drive pair with the end of the worm screw 7,
At least two support portions 9 are provided in worm screw fixing seat 6, the top of all support portions 9 is supported by mobile working platform 10 jointly,
The bottom end of the worm screw fixing seat 6 is provided with sliding block 11, and the sliding block 11 is slidably connected on online rail 2.
There are two types of structure types for the slide unit, the first is double rail type, i.e., line rail 2 is two to be parallel to each other, described
Tooth row 3 is between two lines rail 2；Second is monorail, and tooth row 3 is arranged in the top of line gauge 2.
The course of work of the slide unit based on worm screw tooth row of the embodiment of the present invention is as follows: the workpiece delivered will be needed to be placed on
On mobile working platform 10, then starting servo motor 8, servo motor 8 moves worm screw 7 by pulley drive subband and rotates, by
It is meshed in worm screw 7 with tooth row 3, therefore entire sliding block fixing seat 5 can be driven to move relative to tooth row 3 when the rotation of worm screw 7, herein
In the process, it is slided on the online rail 2 of sliding block 11, realizes the purpose for converting the torque output of servo motor 8 to straight line output；
Since all helical tooths on worm screw 7 can all be contacted with the tooth 4 on tooth row 3, during above-mentioned movement occurs, snail
It is equivalent between bar 7 and tooth row 3 there are a plurality of contact line, compared with traditional rack pinion pair, not only contact area increases
It is big, while a plurality of contact line is uniformly distributed on the length direction of tooth row 3, makes the transmitting of movement more stable, while can also
To carry bigger load.
