When clamping workpiece (G), the positioning spigot place that first workpiece (G) is positioned to described terminal pad (2) centre bore right-hand member, then loads onto described pressing plate (4), secondly starts described cylinder (3), and pressing plate (4) is compressed workpiece (G), so that the endoporus of lathe tool turner (G).
Adopt above technical scheme, the utility model positions the periphery of thin-wall part, and by cylinder and pressing plate, the end face of thin-wall part is compressed, so just make the sidewall of thin-wall part not bear power radially, thereby prevent that thin-wall part from producing distortion diametrically, and then the circularity of assurance thin-wall part endoporus, so just overcome well the defect of traditional processing mode, and this automobile clamper is simple in structure, easy to implement, easy to operate, be specially adapted to the endoporus of processing thin-walled.
As optimal design, the number of described cylinder (3) is three, these cylinders (3) being circumferentially evenly arranged along described positioning disk (2).
Adopt above structure, the number of described cylinder (3) is moderate, and not only thrust is reliable, even, and does not increase the cost of this fixture because selecting too much cylinder (3).
In this case, described threaded mounting hole (4b) be shaped as " 8 " font, the aperture of one of them hole section is greater than the aperture of another hole section, the diameter of described attachment screw (5) head is between the aperture of two hole sections of threaded mounting hole (4b).
Adopt above structure, we just can by attachment screw (5) between two hole sections of threaded mounting hole (4b) mobile come pressing plate (4) described in dismounting, convenient to operation, laborsaving.
As preferably, the circumferentially uniform bolt through-hole (1a) that has of edge on the round plate on described terminal pad (1) left side, the axis parallel of the axial line of this bolt through-hole and terminal pad (1), the bolt facilitating like this by being located in bolt through-hole (1a) is fixedly connected with the ring flange of lathe.
Beneficial effect: the utility model positions the periphery of thin-wall part, and by cylinder and pressing plate, the end face of thin-wall part is compressed, so just make the sidewall of thin-wall part not bear power radially, thereby prevent that thin-wall part from producing distortion diametrically, and then guarantee the circularity of thin-wall part endoporus, so just overcome well the defect of traditional processing mode, and this automobile clamper is simple in structure, easy to implement, easy to operate, be specially adapted to the endoporus of processing thin-walled.
