Description

The connecting rod type transmission mechanism of solid carving machine

Technical field

The present invention relates to a kind of connecting rod type transmission mechanism of solid carving machine, belong to technical field of engraving.

Background technology

Chinese patent number discloses a kind of headgear of solid carving machine for the patent document of CN200820083901.1; As shown in Figure 4; A plurality of rotating disks 103 are installed on this engraving machine; And each rotating disk 103 is driven by a turbine and worm decelerator 102, and servomotor 101 drives 102, the second of first turbine and worm decelerators and follow-up turbine and worm decelerator 102 drives through rotating shaft 104 and shaft coupling 105; The shortcoming of this headgear is to have several rotating disks 103 just to need several turbine and worm decelerators 102, and cost is higher, when most importantly turbine and worm decelerator 102 is worked; The contact-making surface of turbine and worm screw is sliding friction; Therefore wearing and tearing are very fast, are easy to generate the gap, are unfavorable for processing; As because of equidistance not carries out the gap adjustment to worm screw, cost will be multiplied again.In addition, solid carving machine headgear at present commonly used also comprises two kinds of Fig. 5 and Fig. 6.Each rotating disk 203 of the solid carving machine headgear of Fig. 5 drives by a servomotor 201 and turbine and worm decelerator 202; Clearly the cost of this transmission mechanism is higher; And each servomotor 201 and corresponding turbine and worm decelerator 202 relatively independent work, therefore difficult the realization fully synchronously.First rotating disk 303 of the support body engraving machine headgear of Fig. 6 is driven by servomotor 301 and corresponding turbine and worm decelerator 302; Follow-up rotating disk 303 by with first rotating disk 303 rotate synchronously synchronously with 305 and supporting regulating wheel 304 drive with synchromesh gear 306, the regulating wheel 304 of this mechanism is not easy to regulate, when making when being with 305 tension force big slightly synchronously; The load of servomotor 301 is very big; Influence the engraving machine operate as normal, and be with 305 tension force slightly hour synchronously, be with 305 to skid easily synchronously with rotating disk 303; And rotating disk 303 shakes easily, influences machining accuracy.

Summary of the invention

It is low to the purpose of this invention is to provide a kind of cost, can realize that rotating disk rotates synchronously, thereby improves the connecting rod type transmission mechanism of the solid carving machine of machining accuracy.

For reaching the technical scheme that the present invention of foregoing invention purpose adopted be:

The connecting rod type transmission mechanism of solid carving machine comprises lathe bed, is equipped with on the lathe bed by the forward and backward slip workbench of the 3rd screw mandrel drive carrying out; Turntable mounting is installed on the workbench; A plurality of rotating disks evenly are installed on the turntable mounting, the tail-holder rack that can carry out forward and backward slip also is installed on the said workbench, install and the corresponding tailstock of rotating disk on the tail-holder rack; Tailstock and rotating disk constitute clamping device; It is characterized in that said a plurality of rotating disk is driven by connecting rod, connecting rod is connected through pin with each rotating disk, and the position that pin is installed on each rotating disk is consistent; Said connecting rod is driven by driving mechanism, and said driving mechanism comprises drive motors and the decelerator that links to each other with the drive motors axle.

The characteristics of present technique scheme are that a plurality of rotating disks of engraving machine are driven by connecting rod; Connecting rod is connected through pin with each rotating disk; The position that pin is installed on each rotating disk is consistent; Said connecting rod is driven by driving mechanism, and said driving mechanism comprises drive motors and the decelerator that links to each other with the drive motors axle; A plurality of like this rotating disks only need dispose a drive motors and decelerator, have compared with prior art obviously reduced the cost of engraving machine; And all rotating disks drive by a connecting rod, guarantee to realize the synchronous rotation of all rotating disks, have improved the machining accuracy of solid carving machine.

Column is installed in the both sides of said lathe bed, and said column inside is equipped with bearing block, disposes second screw mandrel on the bearing block; Second screw mandrel is driven by servomotor; Be equipped with between two columns by the drive of second screw mandrel and carry out upper and lower mobile crossbeam, be fixed with upper and lower two guide rails on the crossbeam, dispose on upper and lower two guide rails by first screw mandrel and drive the left and right cross slide that horizontally slips; On two cross slides toolframe is installed; Be fixed with a plurality of spindle motors on the toolframe, mounting cutter in the rotating shaft of spindle motor, cutter is corresponding one by one with said clamping device.The present technique scheme is equivalent to the transmission mechanism of vertical direction of the prior art is moved on on two columns; Laterally transmission mechanism is placed on the transmission mechanism of vertical direction; Make like this and have only toolframe on the cross slide and be installed in spindle motor and the cutter on the toolframe; When the left and right slip of cross slide, significantly reduced motional inertia, reduced the impact of cross slide column and lathe bed simultaneously; In addition under the prerequisite that does not increase cross slide width and weight; Can the cross slide on two guide rails be shifted to the end near column; Make cross slide to two ends, the support force of toolframe, thereby reduced the shockproofness at toolframe two ends, and then guarantee product quality near toolframe.

Said lathe bed is made up of base one and base two, and the width of said workbench is corresponding with the width of said base one.The base one general width of solid carving machine is little at present; But the width of workbench is bigger; The present technique scheme has not only reduced waste of material with the width of reduced width to the said base one of workbench, has alleviated the overall weight of solid carving machine; And make complete machine seem small and exquisite, the handled easily personnel operation.
