Description
Technical field
The present invention relates to a kind of micromatic setting, more particularly to a kind of unique 3D printer synchronization belt tension precisely finely tunes dress
Put.
Background technology
At present, the economical 3D printer of the Table top type of FDM technology typically adopts toothed belt transmission, its synchronously with closed loop and
Two kinds of open loop.Using closed-loop synchronization band, its tension adjustment can typically have two kinds of modes：The first is adjusted using tensioner apparatus
The synchronous belt tension of section, typically can also again adjust tension force after the completion of general assembly, but tensioner apparatus generally comprise torsion spring, bearing, open
Bearing up pulley, guide finger, excentric sleeve and some other component, generally require to take more machine construction space, and cost is relatively
Height, assembles also more relatively cumbersome.To increase printing shaping work space as far as possible, the economical 3D printer structure space of Table top type sets
Meter is all very compact, thus seldom adopts tensioner apparatus.By adjusting and locking belt wheel when being utilized in machine general assembly for second
Adjusting synchronous belt tension, so need not take typically can not after the completion of machine construction space and cost, but general assembly for shaft position
Tension force is adjusted again, machine assembling is re-started if it need to adjust tension force again, bother very much.Using open loop Timing Belt, its tension force
Regulation typically can also have two kinds of modes：The first is to adopt tensioner apparatus.As it was previously stated, the economical 3D printer pole of Table top type
Adopt less in this way；Second is using Timing Belt clip.The economical 3D printer majority of Table top type is adopted in this way, it
Need not take machine construction space and cost, but can only the extensive regulation tension force of hand operation, do not accomplish precisely fine setting, and adjust
Section operation is also cumbersome.
Synchronous belt tension has a major impact to 3D printer performance：Excessive belt stretch, can add heavy duty, may make motor
Accidental step-out, causes to print failure；Belt is excessively loose, can affect transmission accuracy, causes to print bad.Additionally, 3D printer is being grown
During phase use Timing Belt can gradual change relax, generally require periodic adjustment synchronously take to appropriateness it is elastic.Therefore, how with comparing
Simple economy and reliable technical scheme, allow users to easily the synchronous belt tension of precisely fine setting, become Table top type economical
One major issue of 3D printer.
The content of the invention
The present invention is exactly in view of the shortcomings of the prior art, there is provided a kind of unique 3D printer synchronization belt tension essence
Quasi- micromatic setting.
To solve the above problems, the technical solution used in the present invention is as follows：

Specific embodiment
Below in conjunction with specific embodiments illustrating present disclosure.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a kind of described synchronous belt tension of unique 3D printer is accurate
Micromatic setting, including linear bearing seat 1, latch segment 2, adjusting slider 3, lock-screw 4a and 4b, regulation locking bed 5, square nut
6th, pad 7, adjusting screw 8, hex nut 9a and 9b.When Timing Belt 12 and motor 10, belt wheel 11, band wheel seat 13, belt wheel
After bearing 14, belt shaft 15 are assembled, two end is locked in linear bearing seat 1 with latch segment 2 and regulation locking bed 5 respectively
On.In linear bearing seat 1 and two grooves are shown, bottom land is the flank of tooth, be covered with the straight-tooth matched with Timing Belt tooth, the two of groove top
The muscle of side is inclined-plane.The top surface both sides of latch segment 2 and regulation locking bed 5 are inclined-plane, and the gradient on each inclined-plane is identical.
After loading onto Timing Belt 12, the left tilted surface 202 and right tilted surface 201 of latch segment 2 respectively with the left groove of linear bearing seat 1
Inclined-plane 101 is bonded to each other, tightens lock-screw 4b, and its coupling mechanism force is decomposed into the normal pressure to left groove inclined-plane 101 and to left recessed
The normal pressure of the groove flank of tooth 102, makes the segment sync band tooth of end one mutually lock with left groove tooth, so as to an end by Timing Belt 12
End is securely locked in the left groove of linear bearing seat 1；Adjust locking bed 5 left tilted surface 502 and right tilted surface 501 respectively with directly
The right groove inclined-plane 104 of bobbin bearing 1 is bonded to each other, tightens lock-screw 4a and hex nut 9b, and it is right that its coupling mechanism force is decomposed into
The normal pressure on right groove inclined-plane 104 and the normal pressure to the right groove flank of tooth 103, make another end Timing Belt tooth with right groove tooth phase
Mutually locking, so as to another end of Timing Belt 12 is securely locked in the right groove of linear bearing seat 1.
Adjusting one end of locking bed 5 has gathering sill 506 and chute 504, and adjusting slider 3 loads and wherein can retreat slip：Its
Middle Slipper 304 is in slide block guide groove 506, cervical region 302 is snapped in chute 504, and by limited step 303 and seam 503
It is spacing to prevent from coming off.Adjusting the other end of locking bed 5 has bayonet socket 505 to press-fit square nut 6.Adjusting screw 8 puts on hex nut
After 9a and pad 7, through the right-hand member hole for adjusting locking bed 5, in being screwed into square nut 6, and rotatable realization is retreated.Adjusting slider 3
Front end be cambered surface 306, the bright finish of Timing Belt 12 is bypassed wherein and is had in advance some tension force during installation；The rear end of adjusting slider 3
For planar end surface 305, the front end face for being conditioned screw 8 is headed on.
By the advance and retreat of the controllable adjustable slide block 3 of turning adjusting screw 8.When partially pine, tension force are less than normal for Timing Belt 12, precession
Adjusting screw 8 makes adjusting slider 3 advance so as to hold out against Timing Belt 12, increases tension force；When Timing Belt 12 is tight slightly, tension force is bigger than normal
When, adjusting screw 8 is moved back in rotation, the rollback therewith of adjusting slider 3, enables Timing Belt 12 to loosen release tension force, reduces tension force.
Adjusting screw 8 for each revolution, adjusting slider 3 will one pitch of displacement exactly, so as to be capable of achieving to Timing Belt
The accurate fine setting of tension force.When production assembling and specialized maintenance, synchronous belt tension can pass through tension detector reading and determine whether
Conformance with standard, turning adjusting screw is precisely finely tuned when not meeting.During user's working service, Timing Belt can be judged according to feel
It is elastic, when partially loose or tight slightly rotatable adjusting screw synchronize band elasticity precise fine-adjustment.
A kind of unique accurate micromatic setting of 3D printer synchronization belt tension of the present invention, can be to synchronous belt tension
Precisely finely tuned, but it is simple and convenient, and only need to take few machine construction space, cost of implementation is also very low
It is honest and clean.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
