Embodiment Construction
[0022] The present invention will be further elaborated below in conjunction with embodiment.
[0023] The invention provides a method for collecting busbar data by dividing the inner wall of the titanium alloy nozzle. The method divides the deviation between the actual busbar and the theoretical busbar on the inner wall of the titanium alloy nozzle into several regions according to the amount of circumferential runout, and uses the arc length of each region The busbar at the point is used as the theoretical busbar for data processing to control the data deviation of the entire area. Through data optimization, the processing program can be generated, which overcomes the problem that the milling toolpath cannot be generated due to the large deviation between the actual busbar and the theoretical busbar.
[0024] Such as figure 1 As shown, the method for collecting busbar data by dividing the inner wall of the titanium alloy nozzle mainly includes the following steps:

The invention relates to a titanium alloy spray pipe inner wall area dividing busbar data collecting method and belongs to the field of spray pipe inner wall data preprocessing. The method includes the following steps that firstly, a busbar data collecting system is established; secondly, a single-point type laser scanning sensor is used for scanning the outer wall of a spray pipe inner wall blank, and busbars having deviation with a theoretical busbar in practical busbars on the spray pipe inner wall blank are obtained; thirdly, a dial indicator is used for measuring the deviation value existing between the busbars having deviation and the theoretical busbar, and area dividing is conducted on every two adjacent busbars having deviation; fourthly, the single-point laser scanning sensor isused for scanning to obtain a data point set of the middle busbar; and fifthly, milling machining is conducted on the spray pipe inner wall blank according to the data of the practical busbar at the middle point position. By means of the method, it is effectively ensured that a machining process can also be generated when the attaching state between the spray pipe inner wall blank and the local part of a jig is poor, the application range of machining is enlarged, consistency of milling groove sizes is ensured, the sampling time is shortened, and the machining efficiency is improved.
Description
technical field [0001] The invention belongs to the field of data preprocessing on the inner wall of a nozzle, and relates to a method for collecting busbar data by dividing the inner wall of a titanium alloy nozzle. Background technique [0002] Chinese Patent Publication No. CN 101412122A, date of publication is April 22, 2009, titled "Vertical Machining Method for Liquid Rocket Engine Nozzle Cooling Channel" discloses a method for vertical processing of liquid rocket engine nozzle cooling channel, the method Based on the busbar data of the drawing, the single-point laser sensor is used to scan the actual busbar of the blank on the inner wall of the nozzle one by one, and the milling toolpath trajectory is calculated after data processing, which is suitable for milling grooves of nozzles that are in good fit with the mold. Its shortcomings are: when the inner wall blank of the nozzle and the mold part are in a poor state of fit, and the actual busbar of the product part de...
