Embodiment Construction

[0051] The present invention will be further described below in conjunction with accompanying drawing.

[0052] Such as figure 1 As shown, a device for detecting the dynamic wetting characteristics of droplets on the tool-workpiece interface includes a microdroplet preparation device 1, a tool block feeding device 2, a workpiece block 3, a visual inspection system and a frame. The micro-droplet preparation device 1 and the cutter block feeding device 2 are arranged side by side; The tool block feeder 2 is aligned with the workpiece block 3 . The tool block 201 of the tool block feeding device 2 performs a relative frictional movement with the workpiece block 3 after dripping the liquid drop to be measured, so that the liquid drop is dragged during the friction process to form liquid traces. The frame includes a droplet preparation support 101 , a droplet storage support 102 , a workpiece block installation support 301 and a visual detection camera support 401 . All above su...

Abstract

The invention discloses a cutter-workpiece contact surface droplet dynamic wetting characteristic detection method and device. It is necessary to detect the dynamic wetting characteristics of the cutting fluid droplets to select the cutting fluid with better performance. The device comprises a micro-droplet preparation device, a cutter block feeding device, a workpiece block, a visual detection system and a rack, wherein the micro-droplet preparation device and the cutter block feeding device are arranged side by side, the micro-droplet preparation device comprises a micro-droplet dipping module and a liquid container, the micro-droplet dipping device is mounted on a bottom plate through a door-shaped micro-droplet preparation support, the micro-droplet dipping module comprises an XZ driving table and a carbon fiber bundle, and the tool block feeding device comprises a tool block, a pressure air cylinder, a second connecting plate and a Y-direction moving platform. The device is advantaged in that an analytic hierarchy process model is established through a droplet wetting angle, the droplet spreading area and the droplet adhesion trace length, and the optimal wettability droplet selection method suitable for different tools and workpiece materials is provided through weight vector calculation.

Description

technical field [0001] The invention relates to a method and a device for detecting the wetting characteristics of droplets on a knife-chip contact surface, in particular to a method and a device for detecting the dynamic wetting characteristics of droplets on the knife-chip contact surface of broach teeth. Background technique [0002] The dynamic wetting characteristics of droplets is an important index to evaluate the performance of cutting fluid. In the process of metal cutting, the cutting fluid with good wetting properties can quickly enter the processing area to play the role of lubrication and cooling, so as to improve the processing quality and reduce tool wear. With the continuous development of the concept of "green production", minimum quantity lubrication technology (MQL) is considered to be a green and environmentally friendly cutting fluid supply method. The flow rate of the traditional pouring type supply cutting fluid is about 50-100L / h, while the MQL is re...
