Fig. 2 is the partial enlarged view of the utility model.
Specific embodiment:
Embodiment: as shown in Fig. 1 to Fig. 2, a kind of polishing of top mount hardware extension bar self-turning mechanism, including machine
Frame 10, be fixed with blowing block 11 in the middle part of the top plate of the rack 10, and the middle part of blowing block 11, which forms, to be upwardly extended
The top surface middle part of cylindrical portion 111, cylindrical portion 111 forms vertical jack 112, and the bottom surface of vertical jack 112 forms bolt apertures
113, the column 114 that is spirally connected is screwed onto bolt apertures 113, and the top for the column 114 that is spirally connected forms support plate 115, and support plate 115 is pressed against
On the bottom surface of vertical jack 112, the top surface of support plate 115 is fixed with buffer spring 116, and the top surface of buffer spring 116 is fixed with
The top surface middle part of connecting plate 117, connecting plate 117 forms hemispherical projections 118, and 100 sleeve of extension bar to be processed is in vertical jack
In 112, the bottom face of extension bar 100 to be processed is pressed against on the spherical surface of hemispherical projections 118, the top of extension bar 100 to be processed at
Type has major diameter portion 101, has rectangular jack in the middle part of the top surface of major diameter portion 101;
The top surface of the top plate of the rack 10 is fixed with upper support frame 12, fixes in the middle part of the top surface of the top plate of upper support frame 12
There is lifting cylinder 13, the push rod of lifting cylinder 13 passes through the bottom surface of the top plate of upper support frame 12 and is fixed with lifter plate 14, goes up and down
The bottom surface of plate 14 is fixed with lower bracing frame 15, and the middle top surface of the bottom plate of lower bracing frame 15 is fixed with rotating electric machine 16, electric rotating
The output shaft of machine 16 passes through the bottom surface of the bottom plate of lower bracing frame 15 and is fixed with square block 161, and 161 sleeve of square block is inserted rectangular
Kong Zhong.
Further, the top surface of the lifter plate 14 is fixed with guide rod 141, and 141 sleeve of guide rod is in upper support frame
In the guide through hole 121 formed on 12 top plate.
Further, guide sleeve 122 is fixed on the inner sidewall of the guide through hole 121,141 sleeve of guide rod is being led
Into set 122.
Further, there is annular groove, 17 sleeve of self-lubricating body is in ring on the inner sidewall of the vertical jack 112
In connected in star, the lateral wall of self-lubricating body 17 is fixed on the inner sidewall of annular groove, and 100 sleeve of extension bar to be processed is in Zi Run
In sleeve body 17.
Further, the top outer wall of the self-lubricating body 17 has radially extending edges 171, radially extending edges
171 are nested in the annular groove having on the inside top wall of vertical jack 112 and are pressed against on the bottom surface of annular groove.
