Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, Figure 2 and Figure 3, the expanding head test tool of the present embodiment, comprises lower link bar 23, and the outer circumference surface of lower link bar 23 is provided with small sleeve 22, and the two ends of small sleeve 22 are fixed on base 21 respectively by front end bearing block 24 and rear end bearing seat 20; Be positioned at base 21 one end and be provided with supporting seat 2, supporting seat 2 is fixed with oil cylinder 1, the head of oil cylinder 1 is provided with cutting ferrule 4, and the head being positioned at lower link bar 23 is provided with the joint flange 5 with cutting ferrule 4 clamping; Small sleeve 22 rear end is formed with flange arrangement, and flange arrangement place is provided with coupling sleeve 15 by securing member, is positioned at coupling sleeve 15 and is provided with nut 16; Also comprise expanding head 19, the support ring 18 of expanding head 19 is connected with coupling sleeve 15 by securing member, and the pull bar 17 of expanding head 19 is tightened in nut 16; Have notch in the middle part of small sleeve 22, pocket bottom mounting plane slide block 12, plane slide block 12 installs centering flange 10 by adjustment packing ring 11; The outer circumference surface of lower link bar 23 is installed follower gear 7, follower gear 7 by securing member and small sleeve 22 one end fastening.
The center line of the pull bar 17 of oil cylinder 1, lower link bar 23 and expanding head 19 is positioned at same axial location.
Lower link bar 23 head outer end is also provided with setting nut 6.
Side, base 21 top is also provided with lubricating pump 25, and lubricating pump 25 is connected with the lubricant passage way hole of expanding head 19 by pipeline.
Base 21 top is also provided with motor 26, and the output terminal of motor 26 is connected with driving gear 27 by reductor, driving gear 27 and follower gear 7 engaged transmission.
Plane slide block 12 is filled with graphite.
Plane slide block 12 adopts high-tensile strength brass material.
Small sleeve 22 is installed respectively by front end lubricating sleeve 9 and rear end lubricating sleeve 14 in the outer circumference surface two ends of lower link bar 23.
The two ends of small sleeve 22 are installed with on front end bearing block 24 and rear end bearing seat 20 respectively by the first lining 8 and the second lining 13.Because the surface finish requirements of lower link bar 23 is high, entering small sleeve 22 is very easily rub impaired, prevents lower link bar 23 precision from reducing so small sleeve 22 two ends to be installed respectively front end lubricating sleeve 9 with rear end lubricating sleeve 14.In addition, small sleeve 22 relies on front end bearing block 24 to be connected with rear end bearing seat 20, and the installation of the first lining 8 and the second lining 13 is namely in order to make small sleeve 22 uniform force.
The present invention to right, selects centering flange 10 and adjustment packing ring 11 and plane slide block 12 to ensure its center in order to lower link bar 23 axis in small sleeve 22, ensures that lower link bar 23 operates steadily, uniform force.
The present invention can complete following functions easily:
(1) spinfunction: (facilitating installing/dismounting expanding head mould)
Motor 26 driven wheel institution staff, thus drive expanding head 19 360 ° of scopes to rotate arbitrarily by the lower link bar 23 of frock, expanding head 19 mold adopts eight equal parts usually, ten deciles or ten are halved, when installing, dismantling, be all that mould is rotated extremely, which improves installation and removal (production line installs more mold exchange or maintenance according to the production steel pipe specification) efficiency of operating personnel.
(2) stretch function: (try out a whole set of expanding head 19, whether inspection assembling is wrong)
A set of expanding head 19 comprises cone, voussoir, the T-shaped key of length, backing plate, multiple workpiece assembly such as outer module forms, before the assembling of expanding machine main frame, first be arranged in this frock, pass through hydraulic power unit, oil cylinder 1 drives lower link bar 23 to stretch back and forth, thus realize pull bar 17 stretching operation back and forth, see whether the T-shaped key of length slides each other at the binding face of cone T-slot energy and voussoir and cone suitable, if this frock improper adjusts in time, so just guarantee that a whole set of expanding head 19 is contained in after on expanding main frame to run suitable (if on expanding machine, overhaul very inconvenience and lose time).
(3) lubricating function: (by oil piping system, oiling is carried out to the face of being slidably matched between the parts that expanding head 19 is installed, expanding head 19 is keeped in repair, maintenance)
Arrange that oil to be flow to the face that is slidably matched between workpiece by lubricating pipe and allocation block by lubricating pump 25, (e.g., the conical surface that rubs of cone and wedge slides; The sliding friction side of short T-shaped key and support ring front end guide ring) produce one deck oil film, reduce sliding friction thus the serviceable life of raising workpiece.Also new expanding head 19 internal oil passages circulation can be checked whether unimpeded by this oil piping system, if do not tested by this frock, be assemblied in and expanding main frame be difficult to find that there is whether road is unimpeded (if there is blocking not find, can reduce the serviceable life of workpiece greatly, if keep in repair also extremely inconvenience above being blocked in, can production be delayed, lower efficiency).
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
