The specific embodiment
In order further to explain technical scheme of the present invention, come the present invention is set forth in detail through specific embodiment below.
Extremely shown in Figure 3 like Fig. 1; It is a kind of multi-purpose type material end face clamping device 100 that the present invention relates to, and comprises mount pad 1, height regulating shaft 11, upper clip 2, lower clamping piece 3, folding rotating shaft 33, folding hydraulic cylinder 4, folding driving-chain 41, tilt cylinders 5 and titling axis 51.
This mount pad 1 is as the mounting seat of whole clamping device 100; It is provided with adjusting screw(rod) 12; This adjusting screw(rod) 12 is used to regulate lower clamping piece 3 present height under the gravity effect; Be the elemental height of clamping, specifically can pass through to change the position of adjusting screw(rod) 12 on mount pad 1, and change the elemental height of clamping.Also be connected with U type switching piece 13 on this mount pad 1, this U type switching piece 13 is fixed on the mount pad 1, and this height regulating shaft 11, titling axis 51 and tilt cylinders 5 are arranged on the U type switching piece 13.
These height regulating shaft 11 rotatable being arranged on the mount pad 1, this tilt cylinders 5 all is fixed on the height regulating shaft 11 with titling axis 51, and this lower clamping piece 3 also can be done the adjustment action of short transverse around height regulating shaft 11.
This upper clip 2 is rotatably connected on lower clamping piece 3 through folding rotating shaft 33; The end of this upper clip 2 and lower clamping piece 3 is respectively arranged with fixture block 21 and following fixture block 31, and this folding hydraulic cylinder 4 and folding driving-chain 41 are between upper clip 2 and lower clamping piece 3 and control the folding angle of upper clip 2 and lower clamping piece 3; Concrete; This folding hydraulic cylinder 4 is fixed on the lower clamping piece 3 through hydraulic cylinder leg 42; And through chain switching piece 43 and link to each other with folding driving-chain 41; Also be provided with sprocket wheel 32 on this lower clamping piece 3, this folding driving-chain 41 pile warp sprocket wheels 32 backs connect with upper clip 2 and are fixedly linked, specifically be with upper clip 2 on chain holder 22 be fixedly linked.
This tilt cylinders 5 links to each other with lower clamping piece 3 transmissions, and drives lower clamping piece 3 along titling axis 51 rotations; Concrete; This tilt cylinders 5 is installed on the cylinder support 52; Then also be provided with the bearing 53 that is used to support titling axis 51 on this titling axis 51, this bearing 53 is preferably taper roll bearing, its when last fixture block 21 with after following fixture block 31 all contacts the clamping face of section bar 200; Because the power of folding hydraulic cylinder 4 is greater than the power of this tilt cylinders 5; Make lower clamping piece 3 rotate, and feasible upward fixture block 21 and the clamping surface of following fixture block 31 perpendicular to section bar 200, thereby realize reliable and stable clamping.
Preferably; Also be provided with elastomer 6 and support 61 between this upper clip 2 and the lower clamping piece 3; On these elastomer 6 settings and the support 61 and two ends contact at respectively on upper clip 2 and the lower clamping piece 3, and the elastic force of this elastomer 6 is slightly larger than the gravity of upper clip 2, these elastomer 6 concrete employing leaf springs.
Like this, a kind of multi-purpose type material end face clamping device 100 that the present invention relates to, the distance between its upper clip 2 and the lower clamping piece 3 can be adjusted by folding hydraulic cylinder 4 and folding driving-chain 41, thereby makes the section bar 200 that can be adapted to different-thickness; Because this upper clip 2 can rotate under the effect of tilt cylinders 5 and titling axis 51 with lower clamping piece 3; So it goes for the section bar 200 of different angles; And under the effect of this folding hydraulic cylinder 4; Can make lower clamping piece 3 overcome the effect of tilt cylinders 5 and make upper clip 2 and lower clamping piece 3, thereby have the characteristics of clamping accurate positioning all perpendicular to clamping face.
In sum, the present invention can be applicable to the section bar 200 of different size, thickness and angle, and can carry out automatic clamping to various section bars 200, has that the suitable dimensions scope is big, chucking power is big and the characteristics of accurate positioning.
Shown in Fig. 4 A and Fig. 4 B, the sketch map when it the present invention relates to clamping device 100 clamping band steels for utilizing, at first tilt cylinders 5 is stretched out, and lower clamping piece 3 makes upper clip 2 and lower clamping piece 3 all perpendicular to the clamping face of band steel section bar 200 around titling axis 51 rotations; Then folding hydraulic cylinder 4 actions, drop-down upper clip 2 get around the last clamping face that closes rotating shaft 33 rotations and make its contact band steel section bar 200, continue the application of force and then can play the effect that clamps band steel.
Shown in Fig. 5 A, 5B, 5C and 5D; Sketch map when it the present invention relates to clamping device 100 cleat angles or flat-bulb steel for utilizing; At first tilt cylinders 5 is regained; Upper clip 2 makes upper clip 2 and lower clamping piece 3 and section bar 200 clamping faces keep certain angle around titling axis 51 rotations, but not necessarily vertical, like Fig. 5 A; Folding hydraulic cylinder 4 action then, drop-down upper clip 2 get around closes rotating shaft 33 and rotates to contact and go up clamping face, like Fig. 5 B; Because section bar 200 positions are not removable, the active force of folding this moment hydraulic cylinder 4 will make lower clamping piece 3 lift around 11 rotations of height regulating shaft, and clamping face under contact is like Fig. 5 C; Last folding hydraulic cylinder 4 continues the application of forces, and lower clamping piece 3 overcomes the active force of tilt cylinders 5, and the rotation around titling axis 51 takes place, and makes the clamping face of upper clip 2 and lower clamping piece 3 equal vertical section bars 200, like Fig. 5 D, and then reaches the purpose of clamping.
The foregoing description and graphic and non-limiting product form of the present invention and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from patent category of the present invention to its suitable variation or modification of doing.
