Drawings
Fig. 1 is a schematic perspective view of a simple and reliable hydraulic clamping milling fixture according to an embodiment of the present utility model.
Detailed Description
In order to further understand the technical scheme of the utility model, the technical scheme of the utility model is clearly and completely described by the embodiment and the attached drawings.
As shown in fig. 1. The simple and reliable hydraulic clamping milling fixture comprises a groove type base 1, action guiding devices respectively arranged on the groove type base, clamping devices and the like.
The groove type base 9 is composed of a bottom plate 10 and side plates 1 which are correspondingly and respectively fixedly connected to two opposite ends of the bottom plate 10 in opposite directions, supporting triangular plates 11 are respectively and fixedly connected between opposite side walls of the two side plates 1 and the bottom plate 10, accommodating grooves 8 are formed in the bottom plate parts between the two side plates 1 and the two side plates, and a workpiece machining operation workbench area is formed by the accommodating grooves 8. The structure is particularly simple and reasonable.
The action guiding device comprises a vertical backing plate 4, four guide posts 3, a flange 2, a hydraulic cylinder 12 and the like, wherein the vertical backing plate is positioned on the inner side of one end side plate 1 of a groove type base 9. One end of each of four guide posts 3 which are transversely arranged is fixedly connected to the corresponding side of the backing plate 4 near four corners, the other end of each of the four guide posts 3 which are transversely arranged is movably connected to the side plate 1 through a guide hole formed in the side plate 1, and the cylinder body of the hydraulic cylinder 12 is fixedly connected to the outer side wall of the side plate 1, the piston rod of the hydraulic cylinder is connected to the flange 2 through a bolt in a threaded manner, and the flange 2 is fixedly connected to the side wall of the corresponding side of the backing plate 4 through a bolt.
The clamping device comprises two V-shaped blocks 5, wherein the two V-shaped blocks comprise a movable V-shaped block 5a, a fixed V-shaped block 5b and the like. The movable V-shaped block 5a is fixedly connected to the corresponding side wall of the other side of the base plate 4, the fixed V-shaped block 5b is fixedly connected to the inner side wall of the other end side plate 1 of the groove base, V-shaped notches of the movable V-shaped block 5a and the fixed V-shaped block 5b correspond to each other in opposite directions, and the V-shaped notch opening direction is the same as the axial direction of the workpiece 7.
During operation, the hydraulic cylinder is controlled to operate so that the movable V-shaped block is far away from the fixed V-shaped block, a workpiece is placed between the movable V-shaped block and the fixed V-shaped block, and then the hydraulic cylinder is controlled to move the movable V-shaped block towards the fixed V-shaped block so as to clamp the workpiece, so that the workpiece can be machined, and after machining is finished, the hydraulic cylinder is controlled to operate so that the movable V-shaped block moves reversely, namely the workpiece is loosened. When clamping a workpiece, the lower end of the workpiece is suspended or supported on the bottom plate of the groove base according to the corresponding specific position of the workpiece processing part or the positioning surface, and the workpiece processing operation working table area formed by the containing groove 8 is matched with the clamping device, so that the workpiece processing part and the clamping part are more approximate.
