Abstract
The utility model relates to a travelling table locating device of a blade trimming and forming press of a large turbine. The travelling table locating device is characterized by comprising locating sleeves B arranged on diagonal positions of two sides of a travelling table, locating sleeves A arranged in the locating sleeves B, a guide sleeve fixedly arranged in a lower cross beam, a locating pin arranged in the guide sleeve, and a drive mechanism used for driving the locating pin to move up and down, wherein the locating pin in the lower cross beam and the locating sleeves A are coaxial. The travelling table locating device has the advantages that the traveling table of the press can be repeatedly and accurately located when being transferred in or out during mould changing; the travelling table locating device is simple in structure, easy to maintain, accurate in locating precision, high in safety performance, and stable in running; errors and abrasion can be prevented during location of an upper mould and a lower mould, and the processing quality of a blade is ensured.
Description
Technical field
The utility model belongs to hydraulic machinery technical field, particularly relates to a kind of large-size steam turbine blade trimming for forming pressing machine moving platform positioner.
Background technology
Steam turbine is main prime mover of modern thermal power plant and nuclear power plant, and it also can be used as the various large-scale working machines of industry in order to drive such as the thrust power of large ship and warship and metallurgy, chemical industry.Blade is building block important in steam turbine, processing vapor turbine blade is all to adopt drop press moulding at present, the dead block fixed structure of the general employing of travelling table of tradition die-forging forming press, because press occurs cumulative errors after frequent shock, easily cause travelling table location inaccurate, and then cause the patrix of mould and counterdie location to occur the wearing and tearing of error and mould, therefore had a strong impact on blade processing quality.
Summary of the invention
The utility model for solve the technical problem existing in known technology provide a kind of simple in structure, can guarantee travelling table accurately location and the large-size steam turbine blade trimming for forming pressing machine moving platform positioner that can improve the quality of products.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
Large-size steam turbine blade trimming for forming pressing machine moving platform positioner, comprise and be arranged on the locational positioning sleeve B of travelling table both sides diagonally opposing corner and be arranged on positioning sleeve A in positioning sleeve B, be packed in guide pin bushing in sill, be arranged on alignment pin and the driving mechanism for driving alignment pin to move up and down in guide pin bushing, the alignment pin in described sill and positioning sleeve A concentric.
The utility model can also adopt following technical scheme:
Described driving mechanism comprises the oil cylinder being arranged in sill, and the in-built piston rod and the connecting rod being connected with piston rod that is useful on jack-up alignment pin of described oil cylinder, is fixed with cylinder mouth guide pin bushing by clamp nut between described piston rod and oil cylinder.
The detection sender mechanism for detection of alignment pin position is equipped with in described connecting rod one end.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, by this device, can realize and when pressing machine moving platform moves in and out when the die change, repeat accurately location, when travelling table immigration puts in place, detect sender mechanism sender, alignment pin, by oil cylinder jack-up, is realized travelling table positioning function, when travelling table shifts out, detect sender mechanism sender, alignment pin is retracted by oil cylinder, and travelling table can freely shift out.This device is easy care simple in structure not only, and positioning precision is accurate, and security performance is high, stable, but also can prevent that error and wearing and tearing from appearring in upper mould and counterdie location, guaranteed the crudy of blade.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, oil cylinder; 2, piston rod; 3, cylinder mouth guide pin bushing; 4, clamp nut; 5, locknut; 6, alignment pin; 7, guide pin bushing; 8, positioning sleeve A; 9, positioning sleeve B; 10, cover plate; 11, connecting rod; 12, sill; 13, travelling table; 14, detect sender mechanism.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, large-size steam turbine blade trimming for forming pressing machine moving platform positioner, comprise and be arranged on the locational positioning sleeve B9 of travelling table 13 both sides diagonally opposing corner and be arranged on positioning sleeve A8 in positioning sleeve B, be packed in guide pin bushing 7 in sill 12, be arranged in guide pin bushing and alignment pin 6 and the driving mechanism for driving alignment pin to move up and down, the alignment pin in described sill and the positioning sleeve A concentric that are slidably matched with it.Described positioning sleeve A end opening is shaped with is convenient to the cone mouth that alignment pin 6 enters, and in positioning sleeve B upper end, by screw, cover plate 10 is housed.
In the present embodiment, described driving mechanism comprises the oil cylinder 1 being arranged in sill, and described oil cylinder is fastening by locknut 5 and sill.The in-built piston rod 2 of jack-up alignment pin and the connecting rod 11 being connected with piston rod of being useful on of described oil cylinder, is fixed with cylinder mouth guide pin bushing 3 by clamp nut 4 between described piston rod and oil cylinder.
The detection sender mechanism 14 for detection of alignment pin position is equipped with in described connecting rod 11 one end.
Operation principle of the present utility model:
By travelling table, promote the action of shifting out with moving into that cylinder is realized travelling table, when travelling table immigration puts in place, detect sender mechanism 14 senders, alignment pin 6 is by oil cylinder jack-up, realize travelling table positioning function, when travelling table shifts out, detect sender mechanism 14 senders, alignment pin 6 is retracted by oil cylinder, and travelling table can freely shift out.
Travelling table is unclamped in the pressure release of this device fluid, and when travelling table moves into, buying oil of this device ejects, and travelling table is located.
