Problems solved by technology
The detection efficiency of this method is not high, but it has high detection accuracy
[0005] At present, the inspection and debugging of the adhesive bonding tooling of aviation composite products in our institute mainly adopts three-coordinate measuring machine equipment, and a small part uses traditional physical measuring tools. Because the three-coordinate measuring machine equipment is expensive, the number is not large. When there are more tooling to be tested, Long-term use of CMM equipment will cause a large number of queues and affect efficiency

Embodiment Construction
[0025] This part is the embodiment of the present invention, which is used to explain and illustrate the technical solution of the present invention.
[0026] A fast digital detection and debugging method for the glued tooling of aviation composite products according to the present invention comprises the following steps:
[0027] Step 1. Use a three-coordinate measuring machine to establish a coordinate system for all the reference planes and reference holes of the bonding tooling, and then inspect the working surface of the bonding tooling. Mark and record the out-of-tolerance value;
[0028] Step 2. Process the area with a large surface tolerance, and use the lever dial indicator to determine the processing value to offset the tolerance value;
[0029] Step 3: Use a three-coordinate measuring machine to inspect the working surface of the processed adhesive tooling, and fine-tune the local out-of-tolerance area until all the working surfaces reach a qualified state.

The invention belongs to the technical field of aviation tool detection, and discloses a rapid digital detection and debugging method of an aviation composite material product cementing tool. The method comprises the steps of detecting a working profile of the cementing tool by using a three-coordinate measuring machine, and marking a profile out-of-tolerance area and an out-of-tolerance value; machining an area with large profile out-of-tolerance, and determining a machining value to counteract the out-of-tolerance value by using a lever indicator; and detecting the machined working profile of the cementing tool by using a three-coordinate measuring machine, and finely adjusting the local out-of-tolerance area till all the working profiles reach the qualified state. According to the method, the high-precision characteristic of digital measurement of the three-coordinate measuring machine is utilized, meanwhile, a traditional physical quantity debugging method is combined, the detection efficiency is high, the detection precision is high, the three-coordinate measuring machine does not need to be used all the time, and limited resources are liberated.
Description
technical field [0001] The invention belongs to the technical field of aviation tooling detection, and relates to a detection method for aviation composite material product bonding tooling, in particular to a rapid digital detection and debugging method for aviation composite material product bonding bonding tooling. Background technique [0002] An important function of the bonding tooling for aerospace composite products is to assist mechanical processing to prevent deformation and skewing of the composite material when it is stressed. The manufacturing compliance of its working surface will be related to the manufacturing accuracy of the product. At present, the inspection and debugging of glue joint tooling mainly adopts the following two methods: [0003] 1. Use traditional physical measuring tools for testing and debugging: that is, use measuring instruments such as height gauges, feeler gauges, and dial gauges to test the tooling profile. The advantage of this method ...
