Abstract

The invention relates to an integrated main gear. The problem that an existing main gear is prone to resonance and poor in reliability is solved. The integrated main gear comprises a rack, a main belt crossbeam, a servo motor, a small synchronous pulley, a large synchronous pulley and a synchronous belt. An anti-collision shaft is arranged on the rack and comprises a rod, two check blocks and a spring, wherein the rod, the check blocks and the spring are arranged on the rack in a penetrating mode. The rack is provided with a tension device used for tensioning the synchronous belt. The tension device comprises an upper wedge block, a lower wedge block, an adjusting bolt, four sliding grooves and four fastening bolts, wherein the lower wedge block corresponds to the upper wedge block and is fixedly connected to the servo motor, the adjusting bolt penetrates through the rack and is fixedly connected with the upper wedge block, the four sliding grooves are formed in the rack, and the fastening bolts penetrate into the four sliding grooves and are fixedly connected with the servo motor. The integrated main gear is convenient to install and simple in structure, reduces resonance between the components and noise, is high in reliability, and saves labor compared with a traditional transversely-installed main gear, and the degree of tightness of the synchronous belt can be adjusted only by adjusting one screw.

Description

Integral type main drive
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 forms by the lower bearing bracket 12 for small synchronous pulley 4 is installed with for the upper spider 11 that large synchronous pulley 5 is installed, upper spider 11 and lower bearing bracket 12 are installed on main belt crossbeam 2, upper spider 11 and lower bearing bracket 12 are not an entirety, easily produce in use resonance, and 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 produce the 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 drive, comprise frame, be fixed together with frame and large synchronous pulley above frame of the main belt crossbeam of left and right directions setting, the servomotor that is arranged on frame below, the small synchronous pulley being connected with the rotating shaft of servomotor, switching, with small synchronous pulley and synchronous pulley is meshed greatly Timing Belt; Described frame is provided with anticollision shaft, described anticollision shaft comprise wear penetrate the bar in frame, be separately positioned on two blocks at 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 the tensioning apparatus for tensioning Timing Belt, described tensioning apparatus comprises wedge, and the adjusting bolt that be connected in lower wedge servomotor on, be located in frame in and with upper wedge be mutually connected corresponding with upper wedge, be opened in four chutes in frame, four wear respectively the fastening bolt of penetrating in four chutes and being connected mutually with servomotor.
Further, in described frame, be also provided with cut-offing protecting switch; For stop head to dash forward because of system problem by power-off.
Further, in two blocks, at least one is nut, and bar is provided with corresponding screw thread; Be convenient to install and regulate the cushion effect of anticollision shaft.
Compared with prior art advantage of the present invention is: this integral type main drive mid frame is as a whole, and traditional main servo motor cabinet, frame and tightening regulator are become one, easy for installation; Simple in structure, 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 Timing Belt tightening regulator, only needing to regulate a screw is adjustable tightness of synchronous belt simultaneously.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described:
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, be fixed together with frame 1 and the main belt crossbeam 2 of left and right directions setting, be arranged on the servomotor 3 of frame 1 below, large synchronous pulley 5 above frame 1 of the small synchronous pulley 4 that is connected with the rotating shaft of servomotor 3, switching, with small synchronous pulley 4 and synchronous pulley 5 is meshed greatly Timing Belt 6; Described frame 1 is provided with anticollision shaft 7, described anticollision shaft 7 comprise wear penetrate the bar in frame 1 71, be separately positioned on two blocks 72 at the two ends, left and right of bar 71, between the block 72 on right side and frame 1 and be socketed in the spring 73 on bar 71; Described frame 1 is provided with the tensioning apparatus for tensioning Timing Belt 6, described tensioning apparatus comprises wedge 91, and the adjusting bolt 93 that be connected in lower wedge 92 servomotor 3 on, be located in frame 1 in and with upper wedge 91 be mutually connected corresponding with upper wedge 91, be opened in four chutes in frame 94, four wear respectively the fastening bolt 95 of penetrating in four chutes 94 and being connected mutually with servomotor 3; In described frame 1, be also provided with cut-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 drives large synchronous pulley 5 to rotate by Timing Belt 6, and 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 presses down lower wedge 92, 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 program problem, whole head all can be thrown out, cut-offing protecting switch 8 stops providing power to head by power-off, anticollision shaft 7 stops head by buffering.
This integral type main drive becomes one traditional main servo motor cabinet, frame and tightening regulator, easy for installation; Simple in structure, all parts are all loaded in frame, have reduced the resonance between each parts, have reduced noise; Integral type main drive is that suspension type is installed, and more traditional horizontal installation is laborsaving; Be integrated with Timing Belt tightening regulator, only needing to regulate a screw is adjustable tightness of synchronous belt simultaneously; This device has also added to be prevented hitting power-off protection apparatus, and trigger switch stops, and has improved production security; Integral type 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 among the scope of the claims of the present invention.
