The adjustable piston ring machining device has simple structure, can conveniently process piston rings, and can effectively ensure design accuracy requirements of the piston rings.
Description
Technical field
The utility model relates to the processing and fabricating equipment of vital part-piston ring in a kind of runner of hydro-generating unit piston cylinder assembling, belongs to the hydraulic generator unit and makes the field.
Background technology
In recent years, along with the manufacturing continuous development of hydraulic generator unit, unit is done bigger and bigger, and each component geometry size is also increasing accordingly.The assembling of runner piston cylinder is the key of the hydraulic turbine, and piston ring is the vital part of piston cylinder, its machining accuracy particularly thickness direction dimensional requirement is very high, and its machining accuracy directly can cause reduce, the wear and tear quickening, service life of leakage of oil, piston ring and the oil cylinder contact-making surface of piston cylinder to reduce even phenomenon such as block.The piston ring of domestic as shown in the figure certain hydraulic generator unit, diameter are 2.4m, and its thickness direction dimensional tolerance only is 0.05mm, and the flatness on two planes is 0.03mm, and the perpendicularity of interior external diameter is 0.03mm.And because the characteristics of piston ring own, has characteristic withstand voltage, good springiness, the diameter dimension of sectional dimension and workpiece itself differs greatly, the rigidity of piston ring is very poor, adding its special serviceability requires to cut (free state gap-clearance of piston rings, the duty piston ring links closely), so the difficulty of processing of piston ring is very big, never is well solved.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, adjustable piston ring process equipment that machining accuracy is high.
The technical scheme that the utility model adopted is, a kind of adjustable piston ring process equipment, comprise base, workbench, pressing plate and cushion block, stationary table is on base, pressing plate and cushion block are in the two ends of workbench respectively, cushion block shape and piston ring inner ring coupling, pressing plate connects arrangement for adjusting height, and cushion block connects holding device.
Preferably, described arrangement for adjusting height comprises pressing plate screw rod, panel nut, heightens screw rod and Height Adjustment nut, the pressing plate screw rod is separately fixed on the base with the bottom of heightening screw rod, the pressing plate screw rod passes the pressing plate end respectively with the top of heightening screw rod, panel nut is connected with the pressing plate screw flight and the clamping platen top, the Height Adjustment nut with heighten screw flight and be connected also bottom the clamping platen.
Preferably, described holding device comprises bearing and hold out against screw, and rest base is fixed on the base by nut, holds out against screw and passes the bearing top and be fixed on the bearing by setscrew nut, holds out against screw end and holds out against cushion block.
Preferably, described cushion block is the inclined-plane with the acting surface that holds out against screw.
Adjustable piston ring process equipment of the present utility model is simple in structure, can easily the machining piston ring, effectively guarantee the design accuracy requirement of piston ring.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is described in further detail, but protection domain of the present utility model is not limited to this.
As shown in Figure 1, a kind of adjustable piston ring process equipment, comprise base 7, workbench 13, pressing plate 2 and cushion block 12, workbench 13 is fixed on the base, pressing plate 2 and cushion block 12 are in the two ends of workbench 13 respectively, cushion block 12 shapes and piston ring 1 inner ring coupling, pressing plate 2 connects arrangement for adjusting height, and cushion block 12 connects holding device.
Described arrangement for adjusting height comprises pressing plate screw rod 4, panel nut 3, heightens screw rod 6 and Height Adjustment nut 5, pressing plate screw rod 4 is separately fixed on the base 7 with the bottom of heightening screw rod 6, pressing plate screw rod 4 passes pressing plate 2 ends respectively with the top of heightening screw rod 6, panel nut 4 is threaded with pressing plate screw rod 4 and clamping platen 2 tops, Height Adjustment nut 5 with heighten screw rod 6 also clamping platen 2 bottoms that are threaded.Described holding device comprises bearing 9 and holds out against screw 11, and bearing 9 bottoms are fixed on the base 7 by nut 8, holds out against screw 11 and passes bearing 9 tops and be fixed on the bearing 9 by setscrew nut 10, holds out against screw 11 ends and holds out against cushion block 12.Described cushion block 12 is the inclined-plane with the acting surface that holds out against screw 11.
When the utility model uses, at first stay process allowance rough turn in piston ring, entad mill out opening.Then base 7 is arranged on the lathe floral disc, its center is on the diameter of piston ring, and pressing plate 2 compresses back light and goes out, and installs workbench 13, pressing plate 2 again and compresses back light and go out, and guarantees flatness.The piston ring free state is placed on the workbench 13, make the cylindrical locating ring with pressing plate 2, heighten bolt and nut and adjust the pressing plate height, make it be close to workbench 13, interior circle is with the taper liner piece and hold out against screw and hold out against, and fixes piston ring, piston ring is close on the workbench 13, process allowance is stayed on half finish turning, two planes, notes in the turning process standing up, and can not time processing put in place.Process milling piston ring faying surface behind thickness direction two planes, hold piston ring tightly faying surface with special-purpose anchor ear in addition and take the jail to the piston ring duty, the piston ring gap place pads by actual, distinguish the inside and outside circle of turning piston ring to the figure paper size with this equipment clamping, finish turning piston ring thickness direction two planes in working order the time are located once more with locating ring in the intact back of car, guarantee dimensional tolerance and the flatness and the perpendicularity of thickness.
