Embodiment Construction

[0031] In order to facilitate understanding of the present invention, the present invention enumerates the following examples. It should be clear to those skilled in the art that the embodiments are only for helping to understand the present invention, and should not be regarded as specific limitations on the present invention.

[0032] A turbine shaft remanufacturing repair process, the turbine shaft to be repaired must be classified, cleaned, and surface treated qualified parts, the surface is dry and there is no residual sand shot, the process includes the following steps:

[0033] Step 1, preliminary measurement: 1) Use a digital display micrometer to measure the diameter of the matching journal between the turbine shaft and the floating bearing, and the matching journal diameter between the turbine shaft and the inner hole of the impeller. Continue to operate the qualified workpiece, and the unqualified workpiece enters the scrapping box; 2) Use a precision The measuring ...

Abstract

The invention provides a turbine shaft refabricating repairing process. The turbine shaft refabricating repairing process comprises the following steps of (1), primary measuring; (2), workpiece installing, specifically, a turbine shaft to be repaired is installed on a desk type instrument lathe, the instrument lathe is started, and the turbine shaft is made to rotate; (3), shaft neck repairing, specifically, the shaft neck repairing comprises coarse grinding, fine grinding and polishing; (4), sealing ring groove repairing, specifically, the sealing ring groove repairing comprises coarse grinding, fine grinding and polishing; (5), workpiece primary cleaning; (6), workpiece fixing; (7), locking screw thread repairing, specifically, operations are performed on the locking screw thread by a threading die, the locking screw thread is repaired, the coaxial degree of the turbine shaft is guaranteed, and the thread groove cleanliness of the locking screw thread is improved; (8), workpiece primary cleaning; (9), ultrasonic wave cleaning; (10), final measuring. By means of the turbine shaft refabricating repairing process, the surface state of the turbine shaft can be restored, the quality of the turbine shaft is made to be as new, and the cost is substantially saved, the material and energy consumption is lowered, and the refabricating rate of a turbocharger is increased.

Description

technical field [0001] The invention belongs to the automobile turbocharger remanufacturing technology, in particular to a turbocharger turbine shaft remanufacturing and repairing process. Background technique [0002] Our country has entered the automobile society. A large number of automobiles are scrapped every year, and the turbochargers used in these scrapped automobiles are also scrapped. At present, a large number of these turbochargers are re-smelted according to the material characteristics of the parts, resulting in cost and material losses. Significant waste, energy consumption, and environmental pollution will increase significantly; a small amount will be reassembled after simple cleaning and sandblasting, resulting in the performance and quality of the produced turbocharger far below the requirements for remanufactured turbochargers , not to mention compared with the same new products. [0003] As a key part of a turbocharger, the turboshaft has complex proces...
