Abstract
An eccentric bolt is mainly applied to an aircraft engine, the eccentric bolt is mostly made of materials such as stainless steel or high-temperature alloy, and the requirements on the mechanical property and machining precision of parts are higher; and as shown in the figure 7 and the figure 8, bolt bodies on the two sides of the eccentric bolt are not positioned at a same axis, thus the working accuracy is poor and the disability rate is higher in a manufacturing process. In order to improve the working accuracy and reduce the rejection rate of the parts, the invention discloses an eccentric resilient bushing utilized as a clamping apparatus for processing the eccentric bolt. In use, bar stock of the eccentric bolt is inserted into the resilient bushing, and then the eccentric resilient bushing is fixed on a turning machine or a chuck of a machining center so as to be processed.
Description
Technical field
The present invention relates to a kind of eccentric resilient bushing that is used to process eccentric bolt class part.
Background technology
Eccentric bolt is mainly used on the aero-engine, and mostly its material is materials such as stainless steel or high temperature alloy, higher to the mechanical performance and the requirement on machining accuracy of part.Like Fig. 7 and shown in Figure 8, because the body of bolt of eccentric bolt both sides is on same axial line, machining accuracy is poor in process, scrappage is higher.
Summary of the invention
For improving machining accuracy and reducing the part scrappage; The present invention discloses a kind of eccentric resilient bushing; As the anchor clamps of processing eccentric bolt, during use the bar of eccentric bolt being inserted should the off-centre resilient bushing, again should the off-centre resilient bushing be fixed on the chuck of lathe or machining center to process.
Processing of this off-centre resilient bushing by cylindric metal bar material; As shown in Figure 1; Eccentric resilient bushing of the present invention is made up of cylindrical shell 1, anti-rotation boss 2, eccentric orfice 3 and regulating tank 4; Be processed with anti-rotation boss 2 in the less side of cylindrical shell 1 barrel thickness, be processed with regulating tank 4 in the bigger side of cylindrical shell 1 barrel thickness.
During use; To insert eccentric orfice 3 like Fig. 5 and the less side of eccentric bolt bar diameter shown in Figure 6; The bolt block 6 that the eccentric bolt bar processes fixed pan in advance and the fixed pan of the anti-rotation boss 2 of eccentric resilient bushing are matched; Regulate regulating tank 4 so that eccentric resilient bushing clamps the less side of eccentric bolt bar diameter, eccentric resilient bushing is clipped on the chuck of lathe or machining center processes then.After the body of bolt that processes a side 8, process opposite side more in the same way and form the body of bolt 7.
Because eccentric resilient bushing of the present invention has overcome the needed eccentric angle of eccentric bolt; So in the process of processing, not only improved machining accuracy, reduced the part scrappage; Also greatly reduce workman's tool setting time and difficulty of processing, effectively improved operating efficiency.

The specific embodiment
The specific embodiment one
As shown in Figure 1, eccentric resilient bushing of the present invention is made up of cylindrical shell 1, anti-rotation boss 2, eccentric orfice 3 and regulating tank 4, is processed with anti-rotation boss 2 in the less side of cylindrical shell 1 barrel thickness, is processed with regulating tank 4 in the bigger side of cylindrical shell 1 barrel thickness.
During use; To insert eccentric orfice 3 like Fig. 5 and the less side of eccentric bolt bar diameter shown in Figure 6; The bolt block 6 that the eccentric bolt bar processes fixed pan in advance and the fixed pan of the anti-rotation boss 2 of eccentric resilient bushing are matched; Regulate regulating tank 4 so that eccentric resilient bushing clamps the less side of eccentric bolt bar diameter, eccentric resilient bushing is clipped on the chuck of lathe or machining center processes then.After the body of bolt that processes a side 8, process opposite side more in the same way and form the body of bolt 7.
The specific embodiment two
Like Fig. 2, Fig. 3 and shown in Figure 4; Eccentric resilient bushing of the present invention is made up of cylindrical shell 1, anti-rotation boss 2, eccentric orfice 3, regulating tank 4 and location-plate 5; Be processed with anti-rotation boss 2 in the less side of cylindrical shell 1 barrel thickness, be processed with regulating tank 4 in the bigger side of cylindrical shell 1 barrel thickness.The effect of location-plate is to increase the chucking power of the eccentric resilient bushing of the present invention to the eccentric bolt bar, also makes this eccentric resilient bushing convenient and be installed in accurately on the chuck of lathe or machining center simultaneously.
During use; To insert eccentric orfice 3 like Fig. 5 and the less side of eccentric bolt bar diameter shown in Figure 6; The bolt block 6 that the eccentric bolt bar processes fixed pan in advance and the fixed pan of the anti-rotation boss 2 of eccentric resilient bushing are matched; Regulate regulating tank 4 so that eccentric resilient bushing clamps the less side of eccentric bolt bar diameter, eccentric resilient bushing is clipped on the chuck of lathe or machining center processes then.After the body of bolt that processes a side 8, process opposite side more in the same way and form the body of bolt 7.
