Detailed Description
The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.
The specific embodiment is as follows: referring to fig. 1 to 4, a clamp for ring-like workpieces comprises a base plate 2, wherein the base plate 2 is fixed on a workbench of a machining center in use, a 180-degree opening and closing pneumatic finger cylinder 5 capable of penetrating through a center hole 11 is arranged on the base plate 2, a supporting table 3 for supporting the workpiece 1 is arranged on the periphery of the 180-degree opening and closing pneumatic finger cylinder 5, a plurality of positioning strips 4 capable of being in contact with the outer side of the workpiece 1 to position the horizontal position of the workpiece 1 are arranged on the top surface of the supporting table 3, a pressing block 51 for pressing the upper surface of the workpiece 1 is rotatably connected to the top of a finger 52 of the 180-degree opening and closing pneumatic finger cylinder 5, and the rotation axis (the pressing block 51 rotates around the axis) of the pressing block 51 is parallel to the rotation axis (the finger 52 rotates around the axis) of the finger 52. In actual use, in order to enable the press block 51 to press the upper surface of the workpiece 1, after the workpiece 1 is placed on the support table 3, the upper surface of the workpiece 1 is slightly higher than the lower surface of the press block 51 when the finger 52 is in the horizontal state.
The briquetting 51 includes column 511, the one end of column 511 rotates with the top of finger 52 to be connected, the other end of column 511 is provided with clamp plate 512, the cross-sectional area of clamp plate 512 is greater than the cross-sectional area of column 511, has reduced pressure, is difficult to crush work piece 1.
