To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
Fig. 1 is a kind of spindle support device assembling schematic diagram provided in an embodiment of the present invention, as shown in Figure 1, mandrel supports
Device includes：Mandrel 10, dissection type liner body 1 and multiple length adjustment bars, dissection type liner body 1 include two and half tube structures, cut open
By two and half tube structure sandwicheds on the mandrel 10, length adjustment bar one end is fixed in dissection type liner body 1 fraction liner body 1,
Multiple length adjustment bars are circumferentially uniformly distributed along 1 outer edge of dissection type liner body, and length adjustment bar includes：Tube-like piece 7, axle sleeve 2, mistake
Connector 3, strut 4, mandril 5 and jacking block component 6 are crossed, tube-like piece 7 is fixedly connected with dissection type liner body 1, and axle sleeve 2 is installed on tube-like piece
In 7,3 both ends of transit joint are equipped with screw thread, and 3 one end of transit joint is connected through a screw thread with axle sleeve 2,3 other end of transit joint with
One end of strut 4 is connected through a screw thread, the threaded hole that axle sleeve 2, strut 4 are connected with transit joint 3 it is oppositely oriented, strut 4
One end of the other end and mandril 5 is connected through a screw thread, and 5 other end of mandril is connected with jacking block component 6, and jacking block component 6 is used for treating
The inner wall of processing cylindrical work pieces 9 offsets.
The embodiment of the present invention is by clamping dissection type liner body 1 on the mandrel 10 and circumferentially equal in 1 outer edge of dissection type liner body
The multiple length adjustment bars of cloth, the other end of length adjustment bar and 9 inner wall of cylindrical work pieces of required processing offset, therefore in clamping cylinder
During shape workpiece 9, it is only necessary to which 10 both ends of stationary spindle are the support that can be achieved to cylindrical work pieces 9, and support device is not straight with cylindrical work pieces 9
Contact, easy to the processing to cylindrical work pieces 9.In embodiments of the present invention, during transit joint 3 in knob length adjustment bar,
Since axle sleeve 2 is opposite with the thread rotary orientation of 4 upper screwed hole of strut so that strut 4 and axle sleeve during knob transit joint 3
Relative telescopic displacement (length adjustment for realizing length adjustment bar) is produced between 2, hence in so that the present invention can support different sizes
Cylindrical work pieces 9, enhances adaptability of the spindle support device to different dimension workpieces, while can also be by replacing different length

There is good greasy property, hence in so that the tolerance plate 62 being arranged on jacking block body 61, which has, reduces tubular work in clamping process
The effect that part 9 is damaged, sets tolerance plate 62 to be suitable for geometric tolerance certain on 9 inner wall of cylindrical work pieces, and can slow down cylinder
The wear-out period of shape workpiece 9, increases the service life of jacking block component 6, reduces the maintenance cost of spindle support device.
Preferably, the end face that jacking block body 61 is connected with tolerance plate 62 is cylindrical surface, the circular arc on 61 cylindrical surface of jacking block body
Outside diameter is identical with 9 diameter of bore of cylindrical work pieces.Jacking block body 61 and the face that cylindrical work pieces 9 contacts are set to cylindrical surface and the face
Circular arc outer diameter is identical with 9 diameter of bore of cylindrical work pieces so that jacking block component 6 is preferably bonded with cylindrical work pieces 9, increases jacking block group
The contact area of part 6 and cylindrical work pieces 9, improves the enabling capabilities of spindle support device.
More specifically, the both ends of the surface of mandrel 10 are equipped with the centre bore of the line on the basis of 10 center line of mandrel, mandrel 10 is axial
Transversal disc constant diameter.Mandrel 10 for both ends with centre bore without ladder optical axis, centre bore is set at 10 both ends of mandrel, just
In the connection of mandrel 10 and lathe, facilitate mandrel 10 to position, improve clamping efficiency, while mandrel 10 is arranged to no multi-diameter shaft just
In the axial transposition installation of dissection type liner body 1 so that spindle support device is suitable for the support of different length cylindrical work pieces 9.
As shown in Figure 1, two and half tube structures of dissection type liner body 1 are connected using removable fasteners, using detachable
Two and half tube structures of fastener connection dissection type liner body 1, quick easy to dissection type liner body 1 remove and install.
In spindle support device provided in an embodiment of the present invention, annular rubber ring is equipped between dissection type liner body 1 and mandrel,
Annular rubber ring is set to increase dissection type liner body 1 and frictional force during 10 clamping of mandrel, so as to strengthen mandrel 10 and tubular work
The effect of moment of torsion transmission between part 9, while set annular rubber ring also to slow down the abrasion speed of mandrel 10 and dissection type liner body 1
Degree, increases the service life of spindle support device.
In the spindle support device clamping cylindrical work pieces 9 provided by the embodiment of the present invention, Fig. 5 is implementation of the present invention
A kind of spindle support device clamping cylindrical work pieces schematic diagram that example provides, as shown in figure 5, first pressing from both sides two dissection type liner bodies 1
It is set in mandrel 10, and the axle sleeve 2 for being threaded hole is loaded in the tube-like piece 7 of dissection type liner body 1, both ends is then carried into spiral shell
The strut 4 of pit all sets threaded transit joint 3 with both ends and is connected and by 3 other end of transit joint with being enclosed in dissection type
Axle sleeve 2 in liner body 1 connects, and the cylindrical work pieces realized on spindle support device to Large Diameter Pipeline, size is installed in using strut 4
9 support, also, use and be threadedly coupled between strut 4, axle sleeve 2 and transit joint 3, the spiral shell that strut 4 is connected with transit joint 3
Therefore the thread rotary orientation in threaded hole that pit and axle sleeve 2 are connected with transit joint 3 by knob transit joint 3 on the contrary, can be made
The movement of relative telescopic occurs between axle sleeve 2 and strut 4, realizes the adjusting of center roller support device size range, need to such as fit
The cylindrical work pieces 9 of larger size scope is answered, can be by replacing strut 4 or transit joint 3, to adapt to larger size cylindrical work pieces 9
Support.Meanwhile 4 other end of strut is connected through a screw thread with mandril 5, also can small range fine setting spindle support device support ruler
Very little scope.Then 5 other end of mandril is connected with jacking block component 6, wherein the hemispherical dome structure 51 in mandril 5 is arranged on jacking block group
In the groove of part 6, when the fit system of groove and hemispherical dome structure 51 make it that jacking block component 6 props up 9 inner wall of cylindrical work pieces, adapt to
A degree of geometric tolerance on 9 inner wall of cylindrical work pieces, then loads jacking block body 61 by hemispherical dome structure using cover piece 63
51 are fixed in groove, while tolerance plate 62 is installed to cylindrical work pieces 9, reduce the damage to workpiece in clamping process.Need
When wanting the larger cylindrical work pieces 9 of the axial length of clamping, replaceable mandrel 10 or adjust distance between two dissection type liner bodies 1 and realize pair
The adaptation of the larger cylindrical work pieces 9 of axial length.
The foregoing is merely a prefered embodiment of the invention, is not intended to limit the invention, all in the spirit and principles in the present invention
