Main shaft annular water spraying device

Abstract

The invention discloses a main shaft annular water spraying device, and belongs to the field of machining machine tool main shafts. The main shaft annular water spraying device comprises an annular end cover main body, a gear ring and water spraying devices; the gear ring cooperates with the annular end cover main body, and can be coaxially rotated relative to the annular end cover main body; an internal water tank is formed in the annular end cover main body; the annular end cover main body is provided with a water inlet communicating with the internal water tank; the annular end cover main body is provided with multiple water spraying devices along the internal water tank; the water spraying devices are provided with nozzles; the nozzles communicate with the internal water tank through the water spraying devices; and when each water spraying device is coaxially rotated along with the gear ring relative to the annular end cover main body, each water spraying device synchronously and consistently swings back and forth in the axial direction relative to the gear ring. The main shaft annular water spraying device is compact in structure and free of occupying external space near mainshafts, can totally save external water spraying pipes, can automatically adjust the positions of the nozzles to achieve higher convenience and accuracy, improves the cutter cutting conditions, reduces the defect of gradual manual adjustment, and improves the automation degree and the machining efficiency of machine tools.

Description

technical field [0001] The invention belongs to the field of mechanical processing machine tool spindles, in particular to the field of mechanical processing spindles and tool cooling, and is used for the supporting parts of mechanical processing machine tools. Background technique [0002] In the CNC milling machine, CNC machining center, and CNC drilling and tapping center in the machining industry, there are three main structural forms of spindle cooling and tool cooling: [0003] 1. If Figure 17 , by spraying cooling water through the bone-saving water pipe 15 near the main shaft, or blowing cooling air through the trachea. [0004] 2. If figure 1 , the cooling liquid is sprayed from the nozzle water outlet 19 near the main shaft through the nozzle water inlet hole 18 through the inside of the main shaft. [0005] 3. If figure 1 , the coolant passes through the main shaft water inlet hole 20 to the tool handle through the center of the main shaft, and then sprays o...
