The present invention is realizes object above, using following scheme：A kind of numerical control walks scheming synchronization guide pin bushing and increases shaft coupling, bag
Include outer tube, inner tube and retainer plate, the outer wall of said inner tube is in axial direction provided with raised line, the inwall of the outer tube be provided with it is described
The first groove that raised line is engaged, said inner tube is set slidably and to be fitted close, the fixation in the outer tube
The diameter of circle is equal to the internal diameter of the outer tube and is detachably mounted to one end inwall of the outer tube, the outer wall of said inner tube
The second groove with the tab parallel is provided with close to the side of the raised line, one end is spacing provided with first in second groove
Block, corresponding position is provided with the second limited block on the inwall of the outer tube other end.
Further, the two side of the raised line and the junction of said inner tube outer wall are provided with the sky for being used for accommodating lubricating oil
Chamber, the cavity have towards the strip opening outside said inner tube.
Further, the cross section of the cavity is circle.
Further, the outer circumference surface of the retainer plate is provided with screw one, and the outer circumference surface of one end of the outer tube is provided with
The screw two coordinated with the screw one, the retainer plate are bolted with the outer tube.
Further, the end face of the retainer plate is provided with screw three.
Compared to the prior art the present invention, has the following advantages that and beneficial effect：
1st, using double-deck stretching structure, the length that can process part is effectively increased, the shaft coupling after improvement can be not
While changing original machine tool, that is, solves the problems, such as lathe insufficient space, and the length that can process part is promoted to
Original about 2 times；
2nd, be provided with the cavity for filling lubricating oil between bilayer sleeve, cavity it is compact to design, can store certain
The lubricating oil of amount simultaneously can be separated out uniformly, effectively reduce the friction between bilayer sleeve.

Embodiment
With reference to Fig. 1 to Fig. 9, a kind of numerical control walks scheming synchronization guide pin bushing and increases shaft coupling, including outer tube 1, inner tube 2 and retainer plate
3, the outer wall of said inner tube 2 is in axial direction provided with raised line 21, and the inwall of the outer tube 1 is provided with what is be engaged with the raised line 21
First groove 11, said inner tube 2 is set slidably and to be fitted close, the diameter of the retainer plate 3 in the outer tube 2
Equal to the outer tube 1 internal diameter and be detachably mounted to one end inwall of the outer tube 1, the outer wall of said inner tube 2 is close
The side of the raised line 21 is provided with second groove 22 parallel with the raised line 21, and one end is provided with first in second groove 22
Limited block, corresponding position is provided with the second limited block on the inwall of the other end of outer tube 1.Such as Fig. 1, Fig. 3, Fig. 4, Fig. 5 institute
Showing, in the present embodiment, the limited block of outer tube 1 and inner tube 2 can use screw to be arranged on positioning hole 1 and positioning hole 2 42,
Wherein, the screw on outer tube 1 inserts into the inner wall and extended in the second groove 22, and the screw in inner tube 2 stretches out to its outer wall, and 2
Individual screw is worked in coordination, and is propped up mutually when inner tube 2 extend out to the end of outer tube 1, is made inner tube 2 be no longer able to, plays limit
Position effect.
With reference to Fig. 8 and Fig. 9, the two side of the raised line 21 is provided with the junction of the outer wall of said inner tube 2 to be used to accommodate profit
