Detailed description of the invention

In order to make those skilled in the art be better understood from this utility model scheme, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is carried out clear, complete description, obviously, described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all should belong to the scope of this utility model protection.

With reference to shown in Fig. 1-2, a kind of adjustable clamping device, including by the front bar being parallel to each other, rear bar, the left bar being parallel to each other, right bar and four legs form the support 1 in four square frame-shapeds, connected by the first connector 5 in the front bar of support 1 and have the first casting die 2, first connector 5 includes the axle sleeve 51 in inverted U and the first rotating shaft 52 being located in axle sleeve 51, it is provided with bearing between axle sleeve 51 and the first rotating shaft 52, two free ends of axle sleeve 51 outwards bend extension and form boss 511, the lower section of boss 511 is provided with cushion structure 512, i.e. there is between boss 511 and support 1 bigger deformation space.Boss 511 is provided with through hole, screw may pass through this through hole and is screwed onto in the front bar of support 1, first casting die 52 hollow cylindrical structure ringwise, its two ends are designed with the first connector, first rotating shaft 52 extends whole first casting die 52 and arranges, and the first casting die 52 can rotate along with the first rotating shaft 52 under the driving of the second force piece 8.

Being rotatably connected to bracing frame 6 on support 1, this bracing frame 6 includes two " Z " the font connecting rods 61 being connected on left bar and right bar, is connected to the first support bar 62 and the second support bar 63 of two " Z " font connecting rod 61 ends.The lower surface of the first support bar 62 is provided with the second rotating shaft 31 being electrically connected with the second force piece 8 by the second connector, this the second rotating shaft 31 outer sheath is provided with the second casting die 3, being provided with cushion structure between second connector and the first support bar 62, the structure of this second casting die 3 is identical with the structure of the first casting die 2.Second support bar 63 is provided with the first force piece 4, concrete, and in the present embodiment, the first force piece 4 is cylinder, and it pulls the second support bar 63 to rotate counterclockwise, and drives whole bracing frame 6 to rotate counterclockwise, thus the second casting die 3 moves down.In order to increase workpiece stability of equilibrium on support 1, rear bar upper surface at support 1 has, by the 3rd connector connection, the 3rd rotating shaft 71 being electrically connected with the second force piece 8,3rd rotating shaft 71 outer sheath is provided with the 3rd casting die 7, it is provided with cushion structure between rear bar and the 3rd connector, the structure of the 3rd casting die 7 is identical with the structure of the first casting die 2, for circular cylinder structure.In order to increase the balance of workpiece further, if workpiece is slim plate construction, parallel between the first casting die 2 and the 3rd casting die 7 can be provided with the 4th casting die, 4th casting die is rotatably connected on left bar and right bar by the 4th connector, being provided with cushion structure between 4th connector and left bar and right bar, the 4th casting die can also be electrically connected with the second force piece 8.

Vertical between first force piece 4 with the second support bar 63 it is provided with expansion link 41, when closing power source, expansion link 41 is in extended state, when opening power source, expansion link 41 shrinks to the first force piece 4 direction, drives the second support bar 63 to rotate counterclockwise, thus drives whole bracing frame 6 to rotate, make the second casting die 3 near the first casting die 2, it is achieved the effect of clamping workpiece.First force piece 4 is also connected with bearing 9, bearing 9 includes the erected parallel the first supporter 91 and the second supporter 92 in first force piece 4 left and right sides respectively, in order to improve the stability of bearing 9, with the first supporter 91 and the second supporter 92 is vertical is fixedly connected with base 94 bottom bearing 9.The at least two that is provided with the sidewall of the first supporter 91 runs through the through hole 93 of sidewall, on the sidewall of the second supporter 92 with the through hole 93 on the first supporter 91 just to position also offer the through hole of equal number, the sidewall of the first force piece 4 is provided with and the protuberance of two side through hole 93 adaptations, this protuberance cocker sets in through hole 93, by the first force piece 4 card is set the through hole 93 into differing heights, thus change the distance between the first force piece 4 and the second support bar 63, thus when promoting or stretch expansion link 41, the rotating angular range of bracing frame 6 changes, thus change the second casting die 3 clamping dynamics to workpiece.

Operation principle of the present utility model is, the workpiece welded moves on the first casting die 2, first force piece 4 drives bracing frame 6 to rotate counterclockwise by pulling expansion link 63, when after the second casting die 3 with absorption surface, first casting die 2 and the second casting die 3 act on jointly by Workpiece clamping, under the driving of the second force piece 8, first rotating shaft 51 drives the first casting die 2 to rotate clockwise, second rotating shaft 31 drives the second casting die 3 to rotate counterclockwise, drive workpiece travels forward, when workpiece motion s is to the 4th casting die and the 3rd casting die 7, it forms supporting role to workpiece, and second force piece 8 drive the 3rd rotating shaft 71 and the first rotating shaft 51 to rotate with identical speed and equidirectional, drive the 3rd casting die 7, further speed up the output of workpiece.First force piece 4 card is set the through hole 93 into differing heights, changes the angle that bracing frame 6 rotates, and then regulate the first casting die 2 and the second casting die 3 clamping dynamics to workpiece.

Above-mentioned detailed description of the invention is used for illustrating this utility model; rather than this utility model is limited; in spirit of the present utility model and scope of the claims, any modifications and changes that this utility model is made, both fall within protection domain of the present utility model.
