Apparatus for measuring shot blasting times of numerical-control shot blasting machine of engine blade

Abstract

The invention relates to an apparatus for measuring a shot blasting times of a numerical-control shot blasting machine of an engine blade. A light source emitter and a photoelectric receiver are correspondingly arranged, an A / D conversion module is arranged in the photoelectric receiver, a counter and a standard time relay are respectively electrically connected with the photoelectric receiver, adisplay device is separately connected with the counter and the standard time relay, the photoelectric receiver is used for receiving a light source emitted by the light source emitter and generatingan analog signal according to the light variation, the A / D conversion module is used for converting the analog signal to a digital signal and transmitting the digital signal to the counter and the standard time relay, the counter is used for counting the light variation times of the photoelectric receiver, the standard time relay is used for counting a working time of the counter, and the displaydevice is used for displaying the times counted by the counter and the time counted by a timer. By adopting the apparatus for measuring the shot blasting times of the numerical-control shot blasting machine of the engine blade, the problems that the traditional measurement method is low in precision and cannot meet the application requirements can be solved, the detection efficiency and the detection precision can be greatly improved, and the measurement cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of aero-engine manufacturing, and in particular relates to a device for measuring the number of shot-peening times per unit time of an engine blade numerical control shot-peening machine. Background technique [0002] With the rapid development of aviation manufacturing, the surface treatment technology and requirements for engine blades are getting higher and higher, especially the high-tech surface shot peening technology is widely used, which requires the nozzle unit time of the CNC shot peening equipment used The number of internal shot peening is calibrated. If the number of shot peening per unit time of the spray head of the CNC shot peening equipment does not meet the technical requirements of the product, it will directly affect the quality of the engine product and bring hidden dangers to production. Therefore, its calibration is particularly important. [0003] Although there are many factors that ...

Problems solved by technology

[0003] Although there are many factors that affect the quality of shot peening of blades by CNC shot peening machines, the parameter of shot peening times per unit time is a very important technical indicator, which directly affects the processing quality of products. If the number of times is greater than the number specified in the technical requirements It will lead to over-processing. If it is less, it will also affect the quality of product processing. At present, the traditional method is that inspectors use stopwatches and visual observation to count the number of shots per unit time. This method is simple, but the accuracy is low and it is prone to multiple , The phenomenon of leakage technology

Up to now, there is no device or instrument specially used to measure the number of shot peening per unit time of the engine blade CNC shot peening machine on the market.
