Processing method of large driven box assembly

Abstract

The invention relates to a method for machining a large-scale driven box assembly part which comprises a driven box and a transition sleeve. The method is characterized by comprising the following steps: S1, respectively performing rough machining of the driven box and the transition sleeve; S2, performing aging treatment of the driven box; S3, after aging treatment of the driven box, respectively performing semi-finishing and partial finishing of the driven box and the transition sleeve; S4, assembling the driven box and the transition sleeve, and then performing finishing of the assembly part; and S5, removing process tables without detaching the assembly part. The method has the following advantages: the advantages of conventional equipment are utilized to not only ensure the machining precision and quality of the driven box assembly part and improve the precision of a gear machine tool but also improve the utilization ratio of the machine tool and lower the machining cost; and therefore, the method can provide convenient conditions and advanced process means for machining the large-scale driven box assembly part on a cutting machine tool.

Description

technical field [0001] The invention belongs to the technical field of gear machine tool manufacturing, in particular to a processing method for a large driven box assembly. Background technique [0002] The driven box is an important part of the whole gear machine tool, because in the whole gear machine tool, the driven box plays an important role in connecting the column, the saddle and the active box, and it is necessary to install the transmission spindle at its center hole, Therefore, the precision and quality requirements of the entire driven box are very high. After assembly, the coaxiality error value of each center hole is required to be less than 0.008mm, and the parallelism error value between the center line of the center hole and the upper end surface and lower end surface of the guide rail should be less than 0.01. mm, so it is difficult to meet the accuracy requirements of the entire assembly using traditional processing methods. The traditional processing me...

[0002] The driven box is an important part of the whole gear machine tool, because in the whole gear machine tool, the driven box plays an important role in connecting the column, the saddle and the active box, and it is necessary to install the transmission spindle at its center hole, Therefore, the precision and quality requirements of the entire driven box are very high. After assembly, the coaxiality error value of each center hole is required to be less than 0.008mm, and the parallelism error value between the center line of the center hole and the upper end surface and lower end surface of the guide rail should be less than 0.01. mm, so it is difficult to meet the accuracy requirements of the entire assembly using traditional processing methods

The traditional processing method is not to make a process table on the driven box, and the driven box and the transition sleeve are processed to the final size before assembly, and then the two are assembled together, so that the reference plane is not uniform due to the lack of a process table , thereby increasing the number of clamping times, and at the same time, each component has been processed to the final size before assembly, which leads to an increase in the cumulative error value of the entire assembly, which cannot meet the design requirements, thereby affecting the accuracy of the entire gear machine tool
