Operation principle of the present invention：
The bottom surface counterbore 102 of end cap seal plate 10 is socketed on the cylindrical type bar that locating dowel 32 and clamping bar 52 are constituted, end cap
The lower surface of sealing plate 10 contacts to realize plane positioning with three limited posts 6；It is connected, is pulled with pull bar 7 by Digit Control Machine Tool
Pull bar 7, pull bar 7 drives the pulled down in sliding groove 13 of sliding seat 2, and sliding seat 2 is connected by long bolt 16 with slip ring 5,
Slip ring 5 is driven to move down so that with locating dowel 32 vertical displacement movement occurs for clamping bar 52, clamping bar 52 moves down,
Because by contact of incline plane, therefore clamping bar 52 can be moved out while producing when moving down between clamping bar 52 and locating dowel 32
It is dynamic so that clamping bar 52 forms interior expansion motion with locating dowel 32 and clamps bottom surface counterbore 102, and drives end cap seal plate 10 simultaneously
Move down, it is ensured that end cap seal plate 10 is not only automatic to be clamped but also contacted automatically with the post 63 of shoring of the upper end of limited post 6, it is ensured that
Plane positioning.
The annular boss 15 of the upper end of support 1 can ensure the coaxial positioning precision on chassis 35.
Dust ring 4 can ensure the precision that slip ring 5 is moved up and down.
The height of the depth ratio sliding seat 2 of sliding groove 13 is big so that sliding groove 13 has enough spaces to be easy on sliding seat 2
Lower movement.
The crossbeam 51 of the lower end of clamping bar 52 can ensure that clamping bar 52 has enough screen resiliences.
End cap sealing plate 10 is fixed on the positioning by locating dowel 32 and clamping bar 52 by the present invention, does not influence end cap seal
The circumferential edges processing of plate 10 so that lathe can once complete the finishing of the circumferential edges to end cap sealing plate, greatly improve
The process velocity of end cap seal plate, improves machining accuracy.
