Description
Technical field
The present invention relates to flat machine field, relate in particular to integral type main drive.
Background technology
Existing straight-bar machines main drive, as shown in Figure 5, frame by for install small synchronous pulley 4 underFrame 12 and forming for the upper spider 11 that large synchronous pulley 5 is installed, upper spider 11 and lower bearing bracket 12 are equalBe arranged on main belt crossbeam 2, upper spider 11 and lower bearing bracket 12 are not an entirety, easy in useProduce resonance, noise is large, poor reliability, and there is no safety device.
Summary of the invention
The invention provides a kind of integral type main drive, be intended to solve existing main drive and easily produceThe problem of resonance poor reliability.
In order to solve above technical problem, the present invention is achieved through the following technical solutions: integral type main transmission dressPut, comprise frame, be fixed together with frame and the main belt crossbeam of left and right directions setting, be arranged on frameLarge above frame of the servomotor, the small synchronous pulley being connected with the rotating shaft of servomotor of below, switchingSynchronous pulley, the Timing Belt being meshed with small synchronous pulley and large synchronous pulley; Described frame is provided with crashproofAxle, described anticollision shaft comprise wear two blocks penetrating the bar in frame, be separately positioned on the two ends, left and right of bar,Between the block on right side and frame and be socketed in the spring on bar; Described frame is provided with for tensioning sameThe tensioning apparatus of step band, described tensioning apparatus comprises wedge, corresponding with upper wedge and be connected in and watchThe adjusting bolt that takes lower wedge on motor, be located in frame and be connected mutually with upper wedge, be opened inFour chutes in frame, four are worn respectively the fastening screw of penetrating in four chutes and being connected mutually with servomotorBolt.
Further, in described frame, be also provided with cut-offing protecting switch; For stoping head because being by power-offSystem problem and dashing forward.
Further, in two blocks, at least one is nut, and bar is provided with corresponding screw thread; Be convenient to installWith the cushion effect that regulates anticollision shaft.
Compared with prior art advantage of the present invention is: this integral type main drive mid frame is as a whole,Traditional main servo motor cabinet, frame and tightening regulator are become one, easy for installation; Structure letterSingle, all parts are all loaded in frame, have reduced the resonance between each parts, have reduced noise, and reliability is high;Integral type main drive is that suspension type is installed, and more traditional horizontal installation is laborsaving; Be integrated with synchronous simultaneouslyBand tightening regulator, only needing to regulate a screw is adjustable tightness of synchronous belt.

Fig. 1 is front view of the present invention;
Fig. 2 is for watching structural representation of the present invention from left front;
Fig. 3 is for watching structural representation of the present invention from left back;
Fig. 4 is the partial enlarged drawing at A place in Fig. 3;
Fig. 5 is the structural representation of existing main drive.
Detailed description of the invention
Consult Fig. 1, Fig. 2, Fig. 3 and Fig. 4, integral type main drive, comprise frame 1, with frame 1Be fixed together and the main belt crossbeam 2 of left and right directions setting, be arranged on frame 1 below servomotor 3,Large synchronous pulley 5 above frame 1 of the small synchronous pulley 4 that is connected with the rotating shaft of servomotor 3, switching,The Timing Belt 6 being meshed with small synchronous pulley 4 and large synchronous pulley 5; Described frame 1 is provided with anticollision shaft 7,Described anticollision shaft 7 comprises wears two of two ends, left and right that penetrate the bar in frame 1 71, are separately positioned on bar 71Block 72, between the block 72 on right side and frame 1 and be socketed in the spring 73 on bar 71; Described machineFrame 1 is provided with the tensioning apparatus for tensioning Timing Belt 6, described tensioning apparatus comprise wedge 91, withUpper wedge 91 is corresponding and be connected in lower wedge 92 on servomotor 3, be located in frame 1 and withAdjusting bolt 93 that upper wedge 91 is connected mutually, be opened in four chutes in frame 94, four and wear respectivelyThe fastening bolt 95 of penetrating in four chutes 94 and being connected mutually with servomotor 3; In described frame 1, be also provided withCut-offing protecting switch 8; In two blocks 72, at least one is nut, and bar 71 is provided with corresponding screw thread.
When use, servomotor 3 drives small synchronous pulley 4 to rotate, and small synchronous pulley 4 is by Timing Belt 6Drive large synchronous pulley 5 to rotate, large synchronous pulley 5 spreads out of power.
In the time that Timing Belt 6 is lax, will rotate adjusting bolt 93, wedge 91 is moved forward, upper wedge willLower wedge 92 presses down, and lower wedge 92 moves down drive servomotor 3, thereby by Timing Belt 6 tensionings,Then by four fastening bolts 95, servomotor 3 is fixed.
When head in operation when cut-offing protecting switch 8, also dash forward continuing, this is mainly system journeyOrder problem, can all throw whole head out, and cut-offing protecting switch 8 stops providing moving to head by power-offPower, anticollision shaft 7 stops head by buffering.
This integral type main drive is integrated into traditional main servo motor cabinet, frame and tightening regulatorOne, easy for installation; Simple in structure, all parts are all loaded in frame, have reduced the resonance between each parts,Reduce noise; Integral type main drive is that suspension type is installed, and more traditional horizontal installation is laborsaving; WithTime be integrated with Timing Belt tightening regulator, only needing to regulate a screw be adjustable tightness of synchronous belt; This dressPut also to have added and prevent hitting power-off protection apparatus, trigger switch stops, and has improved production security; OneFormula main drive structure, mounting means and operation principle.
The foregoing is only specific embodiments of the invention, but technical characterictic of the present invention is not limited to this,Any those skilled in the art is in the field of the invention, and the variation of doing or modification are all encompassed in the present inventionThe scope of the claims among.
