Above-mentioned tapering internal thread machining clamping device, it is characterized in that: described L shaped cover plate is fixedly mounted on described balladeur train by screw, described V-arrangement jaw one is fixedly mounted on described sliding support piece one side by screw, described V-arrangement jaw two is fixedly mounted on described sliding support piece two upsides by screw, and described locating stop piece is fixedly mounted on described L shaped cover sidewall by screw.
The utility model compared with prior art has the following advantages:
(1) this tapering internal thread machining clamping device design is very reasonable, simple and compact for structure, when processing two ends have the branch sleeve of inside tapered thread, after one end inside tapered thread machines, unclamp a little clamp nut, balladeur train can unclamp with support, tightens clamp nut after balladeur train is rotated to 180 °, can continue to process the inside tapered thread of the other end of branch sleeve, thereby this clamping only needs clamped one time can complete two ends processing.
(2) between the support of this tapering internal thread machining clamping device setting and balladeur train, arrange two pairs to determining steel ball, thereby its anglec of rotation is accurately reliable, machining accuracy is high.
(3) operation is very easy for this tapering internal thread machining clamping device, and operating personnel only need use spanner to rotate the clamping that clamp nut can complete connection set meal to be processed, and the labour intensity that greatly reduces operating personnel is low, has improved working (machining) efficiency.
(4) this tapering internal thread machining clamping device volume is small and exquisite, lightweight, and easy accessibility is convenient to carrying.
(5) a lot of parts of this tapering internal thread machining clamping device are all convenient to produce, buy very much, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.
