Abstract
A special fixture for an annular workpiece aims to solve the problem that when the annular workpiece is machined on a lathe, the workpiece needs to be mounted and dismounted twice, and concentricity of the workpiece can not be guaranteed. The special fixture for the annular workpiece is characterized in that a chuck 1 is arranged on the lathe and provided with a jaw 4, and a center clamping piece 3 is arranged in the middle of the chuck. When the center of the workpiece 2 needs to be machined, the outer edge of the workpiece 2 is clamped through the jaw 4 for machining. When machining of the center of the workpiece 2 is finished and the outer edge of the workpiece needs to be machined, the center clamping piece 3 is used for clamping the workpiece 2, the jaw 4 is dismounted, the outer edge of the workpiece 2 is machined, and therefore the purpose of machining the workpiece at one step is achieved.
Description
Technical field
The utility model relates to a kind of a kind of special fixture that ring-like workpiece is carried out lathe processing.
Background technology
When lathe is processed ring-like and the ring-like workpiece of class, process often inside dimension and then unload workpiece, reclamp inside workpiece processing external dimensions, or unload workpiece reprocessing inside dimension after processing external dimensions.But this processing mode has a very large drawback, to causing off-centre in the higher situation of concentricity requirement, is difficult to reach the requirement of high concentricity exactly, and the staff needs twice workpiece loading and unloading when processing a workpiece, and labour intensity is large, and efficient is low.
Summary of the invention:
Goal of the invention of the present utility model mainly is that the technical scheme by the following stated is achieved.At lathe chuck is arranged, lathe drives the chuck rotation.Claw is housed on the chuck, and chuck hub has the center clamping element.When lathe processing work center, claw is clamped the edge of work, process after the clamping.After workpiece centre machines, with laying down claw behind the clamping element clamping work pieces of center, advance again the external process of workpiece.Until workpiece is laid down workpiece after all machining.Workpiece need not be laid down in the middle of process like this, concentricity that can maximized assurance workpiece, and alleviate workman's labour intensity.Therefore the utility model has following advantage:
1, solves ring-like workpiece and added the problem that to load and unload two subjobs man-hour, alleviated workman's labour intensity.
2, because workpiece clamps at chuck from start to finish always, thereby be subjected to displacement, so can guarantee the concentricity of workpiece.
Description of drawings
Accompanying drawing provides structural representation and the operation principle of ring-like workpiece special fixture of the present utility model.
The specific embodiment
Below by embodiment also by reference to the accompanying drawings, structure of the present utility model is further described.
Embodiment: as shown in Figure 1, at lathe chuck 1 is arranged, claw 4 is housed on the chuck 1.Center clamping element 3 is arranged in the middle of the chuck.In the time of needs processing work 2 center, enter processing with claw 4 clamping work pieces 2 outer rims.When workpiece 2 center completion of processing, when needing the processing work outer rim, use center clamping element 3 clamping work pieces 2, lay down claw 4, processing work 2 outer rims, thus finish the purpose of disposable processing work.
