Abstract

PURPOSE:To minimize the decrease of air blow resulting from air loss by supplying pressure air as a main spindle air curtain air through a common pressure controller and a second pressure controller to reduce air pressure for the main spindle air curtain, and supplying the air into a main spindle tapered hole without passing through the second pressure controller at the initial and final times of unclamping action in the case of tool changing. CONSTITUTION:A switch valve V1 is kept in a closed state during the machining of a work. Pressure air A sent from a pressure air source E therefore enters the second pressure controller 3 through a pressure controller 2, and is supplied between a main spindle head 1 and a spindle after reduced into pressure for a main spindle air curtain to always form the spindle air curtain. A tool changer opens the switch valve V1 at the initial and final times of an unclamping action. Thus the pressure air A is supplied between the main spindle head 1 of reduced pressure and the main spindle without passing through the second pressure controller 3. The main spindle tapered hole air blow whose pressure is not reduced acts on a main spindle taper hole to unclamp a tool.

In the above-described spindle air curtain and spindle taper hole air blow, supply piping is provided as a spindle air curtain and a spindle taper hole air blow to different systems via different pressure regulators and open / close valves, respectively. Since the on-off valves are operated to perform the air blow operation at different air blow timings, a complete two-system piping system and its control system are required. Therefore, not only is the device system and control system complicated and expensive, but also the maintainability is deteriorated. Furthermore, since air is blown during the tool change period, there is wasteful air blow and energy loss is large.

Subsequently, as shown in FIGS. 1, 3 and 4, a main shaft taper hole air blow B piped from one pressure air source E through a common pressure regulator 2 and an on-off valve V1 is emitted when a tool is replaced. The opening / closing command e2 of the control means (not shown) that has received the unclamp command e1 controls the opening / closing valve V1 to open / close only for the initial T1 and the final T2 of the unclamp UK period. Due to the opening / closing operation of the opening / closing valve V1, the main shaft taper hole air blow B is blown out by a gap Y between the taper hole 11B and the taper portion 20A of the tool 20 as shown in FIG.
There is no air loss because it operates only when there is. Then, two different pressure air supplies as the pressure air A ′ of the main shaft air curtain K and the pressure air A of the main shaft taper hole air blow B are switched to open and close the opening / closing valve V1 at appropriate times. As a result, the pressure air A from the pressure air source E is supplied as the air blow A ′ for the air curtain of the spindle that is constantly ejected from the gap X between the spindle 11 and the spindle head 1A, but the flow resistance The flow amount into the spindle taper hole 11B becomes larger than this gap X, and it acts as an air blow B of the spindle taper hole 11B.

2. The pressure air from one pressure air source through a common pressure regulator is supplied to the spindle head tip side portion as a spindle air curtain or a spindle taper hole air blow, and the pressure regulator and the spindle head tip side. In addition to interposing an on-off valve that directly transmits the pressure air of the above pressure regulator between the parts, a second pressure regulator for depressurizing the spindle air curtain is installed in parallel with this on-off valve to reduce the pressure of the spindle air curtain. In addition to decompressing air with the second pressure regulator, the pressure air of the main shaft taper hole air blow is configured to be directly supplied from the opening / closing valve that opens at the beginning and end of the unclamp operation. Air blow supply device.
