Abstract
The utility model discloses a marine cylinder sleeve liquid fine turning clamp. A mandrel (1) is a hollow body with an inner hole, expanded sleeves (9) are installed at two ends of the mandrel (1), a front choke plug (3) is installed in the front of the inner hole of the mandrel (1), a rear choke plug (10) is installed at the rear of the inner hole of the mandrel (1), a piston (5) is installed in the front choke plug (3), one end of a push rod (4) is connected with a hydraulic cylinder, the other end of the push rod (4) abuts against the piston (5), axial holes (8) are evenly distributed in a wall of the mandrel (1) along the circumference, radial holes (6) are formed at two ends of the mandrel (1) located in the middle of inner cavities of the expanded sleeves (9), the radial holes (6) and the axial holes (8) are communicated with the front choke plug (3), and vent holes (7) are formed at two ends of the mandrel (1) located on the matched surfaces of the inner cavities of the expanded sleeves (9) and are communicated with the axial holes (8). The marine cylinder sleeve liquid fine turning clamp is simple in structure and runs stably, retained air in a sealed inner cavity of the clamp is removed, clamping force is stable, and slipping of a cylinder sleeve is avoided.
Description
Technical field
The utility model relates to ship cylinder cover fluidity lathe finish fixture, is specifically related to the internal expansion type fixture that passes through fluidity filler and transmit clamping force of ship cylinder cover finish turning processing use.
Background technology
The fluidity internal expansion type fixture that marine diesel cylinder liner finish turning is used, hole is established in its mandrel inside, and ringfeder, front silently, after silently form the cavity of sealing, fill fluidity filler in cavity, make ringfeder rising, clamping cylinder cover by the front silently pressure transmission of middle piston.Facts have proved that fixture in the past exists following shortcoming: when filling fluidity filler after Fixture assembly, in the cavity of sealing, total some air that exist are not yet discharged, and affects stablizing of clamping force, easily cause cylinder jacket to skid man-hour adding.
Summary of the invention
The purpose of this utility model is: a kind of ship cylinder cover fluidity lathe finish fixture is provided, gets rid of the air being detained in cavity, ensure that ringfeder clamps stable.
Technical solution of the present utility model is: this fixture comprises mandrel, ringfeder, before silently, piston, push rod and after silently, mandrel is the ducted body with endoporus, on the flange of mandrel, establish screw, ringfeder interference is arranged on the two ends of mandrel, before be silently arranged on the endoporus front portion of mandrel, after be silently arranged on the endoporus rear portion of mandrel, before piston is arranged on silently in, on the hydraulic cylinder of push rod one end connecting machine tool, the push rod other end withstands piston, on the wall of mandrel along even circumferential distribution axial hole, the two ends of mandrel are positioned at the inner chamber middle part of ringfeder and establish radial hole, radial hole and axial hole and frontly silently communicate, it is characterized in that: the two ends of mandrel are positioned at the other steam vent of establishing of inner chamber mating surface of ringfeder, steam vent communicates with axial hole.
The utility model is simple in structure, stable, gets rid of the air entrapment in fixture closed inner chamber, and when work, clamping force is stable, avoids cylinder jacket skidding.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1 mandrel, 2 screws, before 3 silently, 4 push rods, 5 pistons, 6 radial holes, 7 steam vents, 8 axial holes, 9 ringfeders, after 10 silently.
Detailed description of the invention
As shown in Figure 1, this fixture comprises mandrel 1, ringfeder 9, before silently 3, piston 5, push rod 4 and after silently 10, mandrel 1 is the ducted body with endoporus, on the flange of mandrel 1, establish screw 2, ringfeder 9 interference are arranged on the two ends of mandrel 1, before 3 endoporus front portions that are arranged on mandrel 1 silently, after 10 endoporus rear portions that are arranged on mandrel 1 silently, before piston 5 is arranged on silently in 3, on the hydraulic cylinder of push rod 4 one end connecting machine tools, push rod 4 other ends withstand piston 5, on the wall of mandrel 1 along even circumferential distribution axial hole 8, the two ends of mandrel 1 are positioned at the inner chamber middle part of ringfeder 9 and establish radial hole 6, radial hole 6 and axial hole 8 and frontly silently 3 communicate, it is characterized in that: the two ends of mandrel 1 are positioned at the other steam vent 7 of establishing of inner chamber mating surface of ringfeder 9, steam vent 7 communicates with axial hole 8.
