Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth further below in conjunction with concrete diagram.
Fig. 1 is the structural representation of one embodiment of the invention, comprise a platform base 4, platform base 4 side is provided with stepless locking mechanism 5, stepless locking mechanism 5 is supported by the latch mechanism support 6 be fixed on platform base 4, the opposite side of platform base 4 is provided with feeding module 2, and the top of feeding module 2 is fixed with processing module 3.
As shown in Figure 3, stepless locking mechanism 5 comprises four-bar mechanism 5.2, the bottom of four-bar mechanism 5.2 is provided with handle 5.1, the top of four-bar mechanism 5.2 is provided with brake disc 5.3, through hole is provided with in the middle of brake disc 5.3, be installed with rotating shaft 5.4 in through hole, rotating shaft 5.4 is connected with described latch mechanism support 6 by bearing.This mechanism utilizes the dead-centre position of four-bar mechanism 5.2, determining position rotating to, reaching self-locking state by upwards pulling handle 5.1, compresses brake disc 5.3, realizes the location of rotating shaft 5.4.Need to pull lower handle 5.1 during adjustment and can remove locking, thus ensure freely adjusting of rotating shaft 5.4.
Rotating shaft is connected with fixture 1 near the side of processing module, and fixture 1 as shown in Figure 2, comprises chuck, and chuck is provided with claw 1.3, and claw 1.3 is driven by the bevel gear 1.2 be provided with in chuck by chuck handle 1.1.When rotating chuck spanner 1.1, drive chuck inner cone gear 1.2 rotates, thus drives the claw 1.3 of chuck to link, and the centering realized for blank clamps.The present embodiment adopts adjustable four-jaw chuck centering clamping mode, can realize the clamping for difformity blank.
Feeding module as shown in Figure 4, is comprised cross slide way 2.1 and longitudinal rail 2.2, is driven respectively by handwheel 2.3 by ball screw; Be provided with worm and gear 2.4 above longitudinal rail 2.2, worm and gear 2.4 be fixed with scissors mechanism 2.5.Processing module 3 is fixed on scissors mechanism 2.5.In the present embodiment, processing module is electric cutter, is fixed on feeding module by offset cam.
Ball-screw is driven to move thus the rectilinear movement realized on the transverse and longitudinal direction of plane by rotating handwheel 2.3, in the vertical direction realizes feed by the elevating movement of the scissors mechanism 2.5 that design improves, rotated by worm and gear 2.4 and self-locking thus determine the multiple different machining state of cutter, simultaneously in order to ensure the dimensional accuracy of cutting processing, the size datum detent mechanism on horizontal stroke, vertical, vertical three directions and feed control gear can also being designed, can size datum be provided when controlling horizontal, vertical, vertical three direction feed motions.
Realize quick-clamping to electric cutter by Eccentric earn mechamism, can change tool category as required, when pulling open handle 5.1, quick detach unclamps, and it is fixing that upper lower slide is removed electric cutter, and during by lower handle 5.1, cutter is fixed by knife rest.Can bend arbitrarily because heating wire has, electric cutter can carry out the conversion of multiple simple processing type, can carry out comprising cutting shoulder, grooving, punching, does cutting plane in interior multiple physical treatment operation.Heating wire is fixed by tail end holding screw, and cutting temperature can pass through stepless pressure regulation switch-mode regulation.Adapt to different surface quality needs.
Utilizing platform of the present invention, can foam be material, illustrates related notion in Engineering Drawing by the manufacturing process dynamic image of model; Apply heating wire cutting technique, the heating wire cutter that shape is changeable and the fast and flexible that plug-type rapid changing knife structure achieves for model make; Rely on this platform can design the experiment of various engineering graphics, the corresponding ability of training student 3D solid and two dimension view.
The present invention is mainly used in the private classroom of Course of Engineering Graphics, Engineering Drawing typical model miscellaneous can be made for teachers and students, as passed through mutually, cut friendship, cutting and coal-rock combination body, and the related notion in modelling process in Dynamic Display Engineering Drawing, also can be used as Course of Engineering Graphics inquiry experiment instrument simultaneously, carry out independent thought experiment for student, deepen its understanding to the corresponding relation between 3D solid and two dimension view.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention; the technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and application claims protection domain is defined by appending claims and equivalent thereof.
