Embodiment Construction

[0050] In conjunction with the accompanying drawings, the description is as follows:

[0051] refer to figure 1 , a device for performing reliability tests on two power servo tool holders at the same time, consisting of two tool holders (knife holder A1, tool holder B3), a double tool holder installation device 8, a joint loading device 2, a control cabinet 4, The data acquisition box 5, the console 6 and the horizontal iron 7 are composed.

[0052] The two knife rests are installed on the double knife rest mounting table device 8, and can move along the guide rails on the double knife rest mounting table device 8 driven by the servo motor 16. The joint loading device 2 is located above the double tool rest mounting table device 8 in terms of spatial arrangement, and is arranged between the two tool rests. Simultaneously simulate the loads of two tool holders during cutting, and test the performance of the tool holders.

[0053] The data collection box 5 is placed on the co...

Abstract

The invention belongs to the technical field of mechanical test equipment and method, and relates to a double-tool-rest reliability test device based on combined loading. The double-tool-rest reliability test device comprises two tool rests, a double-tool-rest mounting table device, a combined loading device, a control cabinet, a data acquisition box, and a control console. The two tool rests are mounted on the double-tool-rest mounting table device, and are driven by a servo motor to move along a guide rail. The combined loading device is disposed on the double-tool-rest mounting table device and arranged between the two tool rests, and are used for applying a load to the two tool rests at the same time and detecting the performance of the tool rests. Switching between an ordinary tool bit loading mode and a dynamic tool bit loading mode is realized by means of hierarchical automatic switching, wherein ordinary tool bit loading is based on a direction-adjustable piezoelectric ceramic loading mechanism, and dynamic tool bit loading is based on the mutual support principle of two dynamic tool bits and a bending moment and vibration loading structure. The working conditions of two tool rests are detected simultaneously by one set of image detection mechanism, and the device has a high degree of integration and automation.

Description

technical field [0001] The invention belongs to the technical field of mechanical test equipment and methods, and relates to a reliability test device for combined loading of double tool holders, in particular to a reliability test device that can simulate the working conditions of two CNC tool holders at the same time . technical background [0002] As the key functional component of CNC lathe, the CNC tool post's failure directly affects the machining accuracy and work efficiency of the lathe. Looking at the current reliability test benches of CNC tool holders at home and abroad, most of them can only conduct reliability tests on a single CNC tool holder, and the numerous loading devices and accessories lead to high cost and low space utilization of the test bench. In terms of loading the power head of the dynamic servo tool post, most of the test benches currently only use the dynamometer to load the power head with torque, which cannot simulate bending moment and cuttin...
