A kind of processing thin-walled sleeve bracing or strutting arrangement is disclosed in the description of the Chinese utility model patent that is CN202070928U at notification number, this bracing or strutting arrangement comprises bearing block, one end of bearing block is connected with the Morse taper shank in the mohs tapered bore that is arranged on tail stock while use, the other end at bearing block is provided with support bar along Morse taper shank axial support, is radioactivity is evenly equipped with four length-adjustable support columns on support bar away from one end of bearing block around circumference.When use, tube kind part to be processed is clamped fixing by lathe chuck, the Morse taper shank of bracing or strutting arrangement is arranged in the mohs tapered bore that on tail stock, correspondence is provided with, the support column of support bar end is inserted in sleeve endoporus, and press and be supported on sleeve inner hole wall to play auxiliary fixed support effect by the circular arc top away from the support bar top of support column, thereby ensure the machining accuracy of tube kind part.
But need to be around circumferentially concentrating the bolt hole that support column is installed while offering multiple use on above-mentioned support bar, difficulty of processing is larger on the one hand, also affected on the other hand the intensity of support bar, the number that is arranged on like this support column on support bar can not be a lot, and then can affect the work of bracing or strutting arrangement.
Summary of the invention
The object of the present invention is to provide a kind of tube kind part turning processing positioning tool, offer the technical problem of the bolt hole of support column being installed while using and then affecting support bar intensity to solve need to concentrate in prior art on support bar.
For achieving the above object, tube kind part turning processing provided by the present invention adopts following technical scheme with positioning tool: a kind of tube kind part turning processing positioning tool, comprise support bar, the front end of this support bar is inserted into the bracing or strutting arrangement in tube kind part endoporus while being coaxially equipped with use, described bracing or strutting arrangement comprises the support wheel of coaxial winding in support bar outside, between this support wheel and support bar, be installed with the spoke architecture that supports fixed support wheel, on the outer ring surface of support wheel around being circumferentially evenly equipped with the threaded mounting hole radially extending along support wheel, in each threaded mounting hole, all spiral is equipped with supporting studs, one end that deviates from described support bar of this supporting studs has top while use and is pressed in the top pressure side on tube kind part inner hole wall.
Described spoke architecture comprises the inner ring sleeve being coaxially fixedly set on support bar, the spoke architecture between support bar and support wheel be two ends be connected in respectively on inner ring sleeve and support wheel around circumferentially uniform support column of inner ring sleeve, this support column and described threaded mounting hole were upwards staggeredly arranged in support wheel week.
The rear end of described support bar is by being rotatably equipped with and being assemblied in the Morse taper shank extending along the pivot center of revolute pair backward on tail stock while using with the coaxially arranged revolute pair of support bar.
Described supporting studs comprises the thread segment coordinating with described threaded mounting hole, convex with in one end that deviates from support bar of thread segment along the axially extended optical axis section of supporting studs, the outside dimension of this optical axis section is less than the outside dimension of thread segment, one end that deviates from support bar of described optical axis section is the top pressure side of described supporting studs, and it is dome structure that section is pressed on this top.
The invention has the beneficial effects as follows: the bracing or strutting arrangement on positioning tool provided by the present invention is the supporting role power to tube kind part by spoke architecture, support wheel and supporting studs shared, intensity to each parts and rigidity requirement are just lower like this, need to perforate on support bar, do not affect like this intensity of support bar, the spiral installing hole of offering on support wheel can be offered a lot, can plug so more supporting studs with improve bracing or strutting arrangement support effect.On bracing or strutting arrangement provided by the present invention, be that the mode of adjusting supporting studs by spiral is pushed up to press the top of tube kind part is pressed and supported and centering cylindrical shell center, adjusting range is little like this, adjusts efficient and conveniently, has reduced the time before processing.Positioning tool provided by the present invention is simple in structure, easy to use, has improved greatly the passing rate of processing of production efficiency and tube kind part.
