[specific embodiment]
Refer to shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, in the present embodiment, the stub bar mechanism of automatically twisting of the present invention, it comprises:
Support 100, this support 100 comprises pillar 110 and is located at the gripper shoe 120 on this pillar 110, this gripper shoe 120 is provided with four through holes 121;
Localization tool 200, its side of being located at described gripper shoe 120 is to place product to be processed 300;
Fixed head 400, it is located at the opposite side of gripper shoe 120, and this fixed head 400 is provided with cylinder fixed block 410, on this cylinder fixed block 410, is fixed with cylinder 420;
Connecting plate 500, it is connected with described cylinder 420, is connected with two tooth bars 600 on this contiguous block 500, and this tooth bar 600 is provided with gear teeth structure 610;
Four rotating shafts 700, these four rotating shafts 700 are respectively between two corresponding to described tooth bar 600, these rotating shaft 700 one end are respectively equipped with gear 710, this gear 710 engages with the gear teeth structure 610 on described tooth bar 600, this rotating shaft 700 makes its other end be located in described through hole 121 through fixed head 400, correspondingly fixed head 400 is provided with accommodation hole and therefrom passes for rotating shaft 700, and have groove 720 in this rotating shaft 700, the stub bar of product 300 is inserted in this groove 720, the width of this groove 720 be greater than stub bar width so that this stub bar after being twisted into two parts, from groove 720, directly drop out,
Electric control gear, it comprises power switch and starting switch, in the present embodiment, this starting switch is floor push.
Wherein, described fixed head 400 is provided with four back shafts 430, these four back shafts 430 are between two corresponding to above-mentioned two tooth bars 600, on this back shaft 430, be respectively equipped with bearing 431 with tooth, this bearing 431 with tooth is vertically tangent with described tooth bar 600, to assist this tooth bar 600 better to do rectilinear motion, friction between this bearing 431 with tooth and tooth bar 600 is rolling friction, frictional resistance is little, makes motion steadily, has avoided because of frictional resistance conference, phenomenon stuck tooth bar 600 being occurred.
Wherein, on described fixed head 400, be also provided with two back-up blocks 440, these two back-up blocks 440 correspond respectively to above-mentioned two tooth bars 600, this back-up block 600 is provided with bearing 431 with tooth, and this bearing 431 with tooth is tangent with described tooth bar 600 levels, to assist this tooth bar 600 better to do rectilinear motion, friction between this bearing 431 with tooth and tooth bar 600 is rolling friction, frictional resistance is little, makes motion steadily, has avoided because of frictional resistance conference, phenomenon stuck tooth bar 600 being occurred.
Refer to shown in Fig. 2 and Fig. 4, this course of work of automatically twisting stub bar mechanism is:
Staff is put into product 300 on localization tool 200, and steps on floor push; Then the magnetic valve of cylinder 420 is charged, the piston of cylinder 420 ejects, and promotes connecting plate 500 and does rectilinear motion, and connecting plate 500 is with carry-over bar 600 to do rectilinear motion, tooth bar 600 motions drive the gear 710 being engaged with to rotate, thereby gear 710 rotates drive, rotating shaft 700 is rotated jointly; After rotating shaft 700 rotations, drive the stub bar rotation that is plugged in rotating shaft 700 the insides, this rotating shaft 700 after turning around is twisted into two parts stub bar, and stub bar directly falls down from groove 720, and staff takes product 300 away, place next processed product 300, realized continuous production process; Finally, until cylinder 420 moves to after range, cylinder 420 resets, thereby drives connecting plate 500, tooth bar 600 to reset, and waits for circulation next time.
Automatically the stub bar mechanism of twisting of the present invention, realize the automatically stubborn stub bar of product, save manpower, and twist stub bar by machinery and improved production efficiency, and avoided causing because staff is tired out the affected phenomenon of assembling of product, this is automatically twisted stub bar mechanism to twist into two parts the length of stub bar consistent in addition, and this twists stub bar mechanism and be not subject to the restriction of product structure automatically, solve the too small or stub bar in space due to stub bar place on cambered surface or inclined-plane, cannot be by the problem of the direct milling of milling cutter.
