Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] see Figure 1-5 , the station axis accuracy measurement and adjustment method of the disc type multi-station machine tool of the present invention is composed of a single-station measurement mechanism and a data processing and adjustment method.

[0033] figure 1 It is a schematic diagram of a single-station detection mechanism. figure 1 Among them, detect the mandrel 3 and the lever dial indicator 4. When testing, remove the power head, and replace the power head with the detection mandrel 3. There are threads at the protrusions at the top of the detection mandrel 3 , and the lever dial indicator 4 is fixed on the detection mandrel 3 through threaded connections during detection.

[0034] figure 2 Is the measurement schematic diagram of the invention of the method. figure 2 Among them, 1 is the power plate for placing the motor and tool,...

Abstract

The invention relates to a station axis precision measuring and adjusting method for a disc type multi-station machine tool. A single-station measuring mechanism and a data processing and adjusting guide method are used, and a detection core rod and a dial test indicator are arranged at the position of a station machining main shaft head; round run-out errors of stations on different discs are obtained through a basic error collection method, wherein the basic error collection method comprises the step of using the signal-station measuring mechanism for obtaining single-station rotating round run-out error data. On the basis of the single-station circumference run-out error geometric model, reliability checking and single-station deviation calculation of test data are carried out, and a swarm intelligence optimization method is used for calculating and determining the overall deviation of the discs. The whole discs are adjusted according to the calculated overall deviation result. The station axis precision of the disc type multi-station machine tool can be effectively measured only through simple instruments including the dial test indicator and the like and the software processing technology, the machine tool is effectively adjusted according to the result obtained through measurement, and the aims that the overall precision of the multi-station machine tool is improved and the machining error is reduced are achieved.

Description

technical field [0001] The invention relates to a method for measuring and adjusting the accuracy of a machine tool, in particular to a method for measuring and adjusting the accuracy of a station axis of a disc type multi-station machine tool. Background technique [0002] The disc type multi-station machine tool has multiple stations and multiple power heads. It has advantages in the occasions where parts require multi-process precision machining. Generally, one work disc is equipped with multiple power motors and their processing combination mechanisms, which are called power discs. ; Another working disc parallel to it places the workpiece, which is called the workpiece disc. Usually the power plate remains stationary, and the material is fed through the rotating motion of the workpiece plate, so that the processing of each station can be completed according to a certain processing sequence. Its structural diagram is attached figure 2 shown. [0003] The axis deviatio...
