Problems solved by technology

[0005] The inventor found that the existing minimum quantity lubrication device mainly cools and lubricates the cutting area in the form of hanging a nozzle on one side of the main shaft, which increases the overall volume of the main shaft , it is easy to interfere with the workpiece or tooling during the processing, causing damage to the equipment
If a single channel is processed on the tool or handle, the processing is convenient, but there will be a defect of single-channel micro-lubrication. If a dual-channel is processed on the tool or handle, the dual-channel is generally a Y-shaped channel, the processing is complicated and the processing cost is high.

Embodiment 2

[0149] In Example 1, the angle of the nozzle II-4 of the cutter device II relative to the handle II-1 is fixed and cannot be adjusted automatically. If the spindle speed and other factors are considered, when the spindle speed is too high, the spray will deviate from The cutting area cannot be effectively cooled and lubricated, so the cutting tool device IV is designed on the basis of Example 1. The connection device I, the minimum quantity lubrication supply device III and their assembly relationship in this embodiment are the same as those in Embodiment 1. Combine below Figure 24-Figure 26 Embodiment 2 is described:

[0150] Figure 24 It is the structural diagram of the internal fluid channel of the tool handle and the tool. As shown in the figure, the end mill IV-2 is installed in the tool mounting hole of the tool handle IV-1. A vertical flow channel IV-1-1 is set inside the handle IV-1, and the channel inlet IV-1-2 is set on the conical surface IV-1-3 of the handle I...

Embodiment 3

[0155] In this embodiment, on the basis of Embodiments 1 and 2, a minimal quantity lubrication device V is designed according to different tool specifications. The connection device I, the minimum quantity lubrication supply device III and their assembly relationship in this embodiment are the same as those in Embodiments 1 and 2. Combine below Figure 27-Figure 31 Embodiment 3 is described:

[0156] The micro-lubrication device V includes a tool holder V-1, an end mill V-2, a spray head V-3 and a screw V-4.

[0157] In this embodiment, the diameter of the tool is greater than or equal to the diameter of the shank. Taking the end mill and the shank of the end mill as an example, the structure of the shank and the tool is as follows: Figure 27 shown. A vertical flow channel Ⅴ-1-1 is set in the handle Ⅴ-1, and passes through to the bottom end surface Ⅴ-1-4 of the handle Ⅴ-1, and the inlet Ⅴ-1-2 of the flow channel Ⅴ-1-1 It is arranged on the conical surface V-1-3 of the han...

Embodiment 4

[0164] This embodiment discloses a working method of a micro-lubrication milling device. The main shaft drives the tool handle and the tool to rotate to process the workpiece. The gas inlet port is connected, and the cutting fluid supply mechanism and the gas supply mechanism alternately inject cutting fluid and gas into the flow channel. The cutting fluid and gas are mixed in the flow channel to form aerosol, and the aerosol is ejected from the flow channel to clean the tool and the processing area. Cooling and lubrication.

Abstract

The invention relates to a minimum lubrication milling device and a working method. The device comprises a workbench, a main shaft connected with a power system, a cutter handle and a sliding ring, wherein one end of the cutter handle is fixedly connected with the main shaft, the other end of the cutter handle is fixedly provided with a cutter, a flow channel is arranged inside the cutter handle and / or the cutter, the sliding ring is slidably arranged on the periphery of the main shaft in a sleeving mode in the circumferential direction of the main shaft, the sliding ring is fixed to a shell of the power system, the sliding ring is connected with a cutting fluid supply mechanism through a cutting fluid inlet, the sliding ring is connected with a gas supply mechanism through a gas inlet, the flow channel is configured in the mode that under relative rotation of the cutter handle and the sliding ring, one end of the flow channel can alternately communicate with the cutting fluid inlet and the gas inlet, the other end of the flow channel is used for spraying out aerosol, and according to the milling device, the minimum lubrication effect is guaranteed, and meanwhile the improvement cost of the cutter and the cutter handle is reduced.

Description

technical field [0001] The invention relates to the technical field of machining equipment, in particular to a micro-lubrication milling device and a working method. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Compared with the traditional pouring external cooling lubrication method in the field of mechanical processing, minimal quantity lubrication technology (MQL) is more suitable for the concept of green manufacturing and sustainable development. It refers to a technology that mixes and atomizes a small amount of lubricating liquid, water and gas with a certain pressure, and then sprays it into the cutting area for cooling and lubrication. Water and high-pressure gas play a cooling role, and oil plays a role in lubricating the cutting zone and prolonging the life of the tool. [0004] The minimum quantity lubrication supply system can be r...
