Abstract
The invention discloses a jet pipe and a method for manufacturing the jet pipe. The jet pipe comprises a head part and a pipe part, wherein the pipe part and the head part are integrally formed. The diameter of the head part is phi 4.2 mm. The pipe part comprises a wide-diameter section and a contracting section. The diameter of the wide-diameter section is phi 2.62 mm. The finish degree of the wide-diameter section is Ra 0.4 microns. The cylindricity of the wide-diameter section is 0.005 mm. The diameter of the upper end of the contracting section is phi 2.5 mm. The diameter of the lower end of the contracting section is phi 2.3 mm. The concentricity of the lower end of the contracting section and the wide-diameter section is 0.01 mm. An inner hole is formed in the pipe part. The diameter of the inner hole is phi 1.2 mm. The depth of the inner hole ranges from 26.5 mm-0.1 mm to 26.5 mm+0.1 mm. A threaded hole is formed in the free tail end of the pipe part. The nominal diameter of the threaded hole is 1.8 mm. The tolerance zone of the threaded hole is H5. The depth of the threaded hole is 5 mm. The concentricity of the threaded hole and the wide-diameter section is 0.02 mm. An opening communicating with the inner hole is formed in the head part. The stability and production efficiency of products are improved.
Description
technical field [0001] The invention relates to the field of mechanical processing, in particular to a jet tube and a manufacturing method thereof. Background technique [0002] The hydraulic servo motor system is a commonly used servo control system in engineering. It has the characteristics of fast response, high power / weight ratio, high load rigidity, and high cost performance. It can realize high-precision, high-speed and high-power control. Therefore, hydraulic servo motor systems are widely used in aerospace, metallurgy, ships, machine tools, power equipment and coal mining machinery. The jet tube involved in the present invention is one of the key components in the hydraulic servo motor system. The jet tube has high requirements on size and shape, so the processing is difficult, resulting in a high scrap rate, low production efficiency, and poor quality. Stable, not ready for mass production. Contents of the invention [0003] The technical problem to be solved by...
