Further, the supporting shaft is of a hollow structure.
Further, one end of the supporting shaft is provided with an outwards protruding boss, and the center of the boss is provided with a center hole.
Further, the supporting shaft part at one end of the limiting ring is a clamping section.
After the structure is adopted, the utility model has the beneficial effects that:
According to the utility model, the workpiece is clamped and limited by arranging the pair of clamping assemblies, and then the clamping assemblies are fixed by the fastening nuts, so that the workpiece can be fixed, quick installation is realized, and meanwhile, the fastening nuts can adjust the pressing force of the clamping assemblies, so that the workpiece is prevented from being extruded and deformed in the fixing process.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Reference numerals illustrate:
1 supporting shaft, 2 clamping components, 21 clamping blocks, 3 fastening nuts, 4 limiting rings, 5 bosses, 6 center holes and 100 machined parts.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be further described in detail below with reference to the accompanying drawings and detailed description. It should be understood that the detailed description is presented by way of example only and is not intended to limit the utility model.
Referring to fig. 1, a fixing device for finish machining of an outer circle piece comprises a support shaft 1, the outside left and right sides of the support shaft 1 is slidingly sleeved with a clamping assembly 2, the clamping assembly 2 is of a split structure and is composed of a plurality of clamping blocks 21 of conical structures, the whole clamping assembly after combination is of a conical structure, a machining piece 100 is placed between the clamping assemblies 2 in a conical tip opposite mode, the outside left and right sides of the support shaft 1 are further connected with a fastening nut 3 in a threaded mode and are fixedly provided with a limiting ring 4, and the fastening nut 3 and the limiting ring 4 are used for fixing the fastening assemblies 2 on the left side and the right side respectively and limiting the limiting ring 4. Specifically, firstly, a proper pair of clamping blocks 21 are taken out according to the diameter of a workpiece, then one clamping block 21 is sleeved on the support shaft 1 and abuts against the limiting ring 4, then the workpiece 100 is sleeved on the support shaft 1 and the clamping blocks 21, then the other clamping block 21 is sleeved on the support shaft 1, the two clamping blocks 21 lift the workpiece 100 and are in a suspension state, and then the clamping blocks 21 are fixed through the lock nuts 3; the clamping blocks 21 on the clamping assembly 2 can be selected according to the diameter of the workpiece, and the proper clamping blocks 21 are selected to ensure that the workpiece can be positioned on the inclined plane of the clamping blocks 21, so that the workpiece is in a suspension state, and the machining is facilitated.
In this embodiment, the supporting shaft 1 has a hollow structure, which reduces the mass of the supporting shaft 1 and facilitates operation.
In this embodiment, one end of the supporting shaft 1 is provided with an outwards protruding boss 5, and the center of the boss 5 is provided with a center hole 6, so that the center tailstock of the machine tool is supported, and the fixing tool is well suitable for machining of the machine tool.
In this embodiment, the supporting shaft at one end of the limiting ring 4 is a clamping section for clamping and fixing the machine tool.
The foregoing is merely illustrative of the present utility model and not restrictive, and other modifications and equivalents thereof may occur to those skilled in the art without departing from the spirit and scope of the present utility model.
