Problems solved by technology
[0002] With the rapid growth of industrial production, the application of thin-walled structural parts is becoming more and more extensive. Due to the complex structure and wall thickness of these parts, the traditional process mainly includes the following steps: blanking, rough turning, semi-finishing turning, drilling, Finishing hole, hobbing, grinding plane, post-processing, inspection; turning processing is used in the processing process, but in the processing process, due to the poor rigidity of the parts, deformation is easy to occur, so the accuracy of the processed parts cannot be guaranteed, and it is necessary to use Turning, process compensation and other methods for shape correction lead to low production efficiency and difficulty in quality assurance, which makes it difficult to exert processing efficiency; fierce market competition requires product development and production cycles to be shorter and shorter, and traditional processing techniques and manufacturing methods have become difficult. Adapt to the high-quality processing requirements of such thin-walled parts

Embodiment Construction
[0023] The following are specific examples to further illustrate the technical solution of the present invention:
[0024] A processing technology for a speed-measuring gear ring of a thin-walled part, comprising the following steps:
[0025] 1) Material selection and cutting:
[0026] Select 12 mm Q345 seamless steel plate, and the cutting size is: Φ430×Φ366×12 mm; because Q345 steel has good mechanical properties, it can reduce deformation;
[0027] 2) Rough turning processing:
[0028] On the C630 horizontal lathe, the inner and outer circles and end faces of the gear ring are roughly turned, the outer circle is to Φ422±0.20 mm, the inner circle is to Φ372±0.20 mm, and the thickness is 9±0.10 mm; use a horizontal lathe to balance the gravity on the gear ring , can reduce the deformation of the gear ring during reprocessing;
[0029] 3) Drilling die seam for fine turning:
[0030] Cool for at least 24 hours after rough turning, and the inner circle of the finish turning ...

Abstract
The invention relates to a processing technology of a thin wall element, in particular to a processing technology for an annular thin wall element of a motor speed test gear, which is used for a track. The processing technology comprises the following steps of: selecting a material, blanking, roughly processing, finely drilling a jig and a slot, drilling a hole, tapping, finely stitching two planes, finely stitching an inner circle and an outer circle, processing burr, galvanizing and lettering. By adopting the technical scheme disclosed by the invention, the deformation of the thin wall element is reduced, time and labor are saved, and the processing precision of the thin wall element is greatly improved.
