Abstract
The invention relates to a detection system for a steam turbine blades. The system includes a blade fixing apparatus and a detection apparatus. The blade fixing apparatus includes a bottom board, a blade root positioning mechanism and a blade crown positioning mechanism. The detection apparatus is composed of a positioning set, a detection template and a radiation apparatus. The blade crown positioning mechanism, the blade root positioning mechanism, the positioning group and the radiation apparatus are all disposed on the same side of the bottom board. The positioning group is disposed between the blade crown positioning mechanism and the blade root positioning mechanism. The detection template matches the positioning group. The radiation apparatus is disposed behind the blade crown positioning apparatus. According to the invention, the detection system is advantaged by being able to detect whether the convex line inside the steam turbine blades meet manufacturing requirements in a rapid and easy manner, and can save power.
Description
Technical field
The present invention relates to back arc lines detection means in a kind of turbine blade, especially a kind of device that can quickly detect back arc lines in turbine blade.
Background technology
In the production process of turbine blade, need to measure its interior, convex profile and chord width, determine if to conform to quality requirements.Originally check the quality condition of interior, convex profile and chord width processing, need to make different measurers to detect, measuring the interior of same blade, convex profile and chord width must just use three kinds of measurers, extremely inconvenience, and during being detected, need staff with the naked eye to go to be observed, compare and lose time and energy.
The content of the invention
The technical problem to be solved is to provide a kind of device for detecting back arc lines in turbine blade that can quickly, easy.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is：Back arc lines detection means in one, its innovative point is comprising blade fixing device, detection means；
Blade fixing device includes base plate, blade root detent mechanism and integral shroud detent mechanism, blade root detent mechanism and integral shroud detent mechanism are installed in the same face of base plate, blade root detent mechanism is made up of blade root positioning boss, located lateral bar A and radius rod, integral shroud detent mechanism is made up of integral shroud positioning boss and located lateral bar B, the located lateral B bar in located lateral bar A and integral shroud detent mechanism in blade root detent mechanism is located at the same side of positioning boss, and radius rod is arranged on the rear side of blade root positioning boss；
Detection means is by positioning group, detection template and irradiation unit are constituted, positioning group is located at integral shroud detent mechanism and blade root detent mechanism centre position, positioning group is made up of some locating rods, each two locating rod constitutes one group of positioning group, detection template is placed in the gap between locating rod, detection template matches with positioning group, detection template is divided into inner arc molded line detection template and back arc lines detection template, irradiation unit includes light irradiator, travel switch, programmable logic controller (PLC) and impermeable light shield, light irradiator is arranged on the dead astern of integral shroud positioning boss, impermeable light shield is cased with light irradiator, impermeable light shield is provided with a circular port near the side of integral shroud positioning boss, circular port is in same level position with light irradiator, travel switch is arranged on integral shroud positioning boss, travel switch is connected with the input terminal of programmable logic controller (PLC), the outlet terminal of programmable logic controller (PLC) is connected with the power supply of light irradiator.
Advantage using said apparatus is：In detection, only back arc lines detection template in correspondence blade need to be placed in corresponding positioning group, can be carried out detection, and when whether back arc lines meet production requirement in observation, only need to stand see whether to see that light just can be with the opposite of lamp light transmitter, it is very convenient, the power supply of lamp light transmitter is controlled additionally by travel switch, the effect of power saving can be reached.
Description of the drawings

Fig. 2 is the schematic diagram of inner arc detection template of the present invention.
Fig. 3 is the schematic diagram of present invention back of the body arc detection template.
Specific embodiment
From institute's diagram of Fig. 1, Fig. 2 and Fig. 3, the fan blade of the present invention includes blade fixing device and detection means with detecting system.
Blade fixing device includes base plate 4, blade root detent mechanism and integral shroud detent mechanism, blade root detent mechanism and integral shroud detent mechanism are installed in the same face of base plate 4, blade root detent mechanism is made up of blade root positioning boss 7, located lateral bar A5 and radius rod 6, integral shroud detent mechanism is made up of integral shroud positioning boss 1 and located lateral bar B2, the located lateral bar B2 in located lateral bar A5 and integral shroud detent mechanism in blade root detent mechanism is located at the same side of integral shroud positioning boss 1 and blade root positioning boss 7, and radius rod 6 is arranged on the rear side of blade root positioning boss 7；
Detection means is by positioning group, detection template and irradiation unit are constituted, positioning group is located at integral shroud detent mechanism and blade root detent mechanism centre position, positioning group is made up of some locating rods 3, locating rod 3 is fixed on base plate 4, each two locating rod 3 constitutes one group of positioning group, detection template is placed in the gap between locating rod 3, detection template matches with positioning group, detection template is divided into inner arc molded line detection template 8 and back arc lines detection template 9, irradiation unit includes light irradiator 11, travel switch 12, programmable logic controller (PLC) and impermeable light shield 10, light irradiator 11 is arranged on the dead astern of integral shroud positioning boss 1, impermeable light shield 10 is cased with light irradiator 11, impermeable light shield 10 is provided with a circular port near the side of integral shroud positioning boss 1, circular port is in same level position with light irradiator 11, travel switch 12 is arranged on integral shroud positioning boss 1, travel switch 12 is connected with the input terminal of programmable logic controller (PLC), the outlet terminal of programmable logic controller (PLC) is connected with the power supply of light irradiator 11.
When specifically being detected using said apparatus, the blade root of blade and integral shroud are placed on blade root positioning boss 7 and integral shroud positioning boss 1 first, the travel switch 12 being now arranged on integral shroud positioning boss 1 is triggered, the programmable logic controller (PLC) being connected with travel switch 12 is after the signal for receiving travel switch 12, connect the power supply of light irradiator 11, open light irradiator 11, then the inner arc detection template 8 of different model and back of the body arc detection template 9 are individually positioned between the gap of corresponding locating rod 3, operator station observes on the opposite of light irradiator 11, if light can be seen, then illustrate that blade is undesirable, if can't see light, then illustrate that blade meets production requirement.After a crop leaf measuring is complete, after taking out blade, travel switch 12 on integral shroud positioning boss 1 is triggered again, the programmable logic controller (PLC) being connected with travel switch 12 is after this signal for receiving travel switch 12, break the power supply of light irradiator 11, light irradiator 11 is closed, electric power is saved.
