And a spindle partitioning device of an opposing two-spindle lathe.
    [15] In general, the opposite two-spindle lathe is installed so that two spindles face each other. In order to reduce productivity and reduce work space by using one bed, it is possible to work continuously in both spindles and to improve productivity. It is used.
    [16] However, since such a conventional two-axis lathe is not provided with any blocking device in the middle of both spindles, when the workpieces that are bitten by both spindles are large in size and are processed at the same time in close proximity, a chip is used. The impact had both sides and had a problem of scratching the workpiece.
    [17] In addition, if the workpiece is removed from both spindles by using a device that automatically loads / unloads the workpiece, such as a gantry loader, while simultaneously cutting the workpiece with different machining time on both spindles When unloading the workpiece on one spindle and biting a new workpiece, the chuck must be opened. In this process, chips splashing from the opposite spindle flow into the jaws of the chuck, causing an error in clamping of the workpiece. If this progresses, there is a problem that the spindle causes severe vibration and damages the workpiece as well as the spindle.
    [18] In addition, when a user manually bites or removes a workpiece, the worker is always in danger by the workpiece rotating at a high speed from the opposite side and a tool that may not move anywhere. When the workpiece is detached after completion, another problem arises that delays working time and lowers productivity.

    [21] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
    [22] As shown in FIGS. 1 to 7, the cover frame 30 is installed at the front and rear sides between the two spindles 20 and 22 and the cover frame 30 is installed inside the cover frame 30 to move in the front and rear directions. It is inserted between the pneumatic cylinder 40 and the door guides 50 and 52 provided at regular intervals downward from the cover frame 30 and the door guides 50 and 52 to slide back and forth, and pneumatically The partition door 60 which is connected to the cylinder 40 and moves back and forth while blocking or opening between the spindles 20 and 22, and the flow path flowing through the pneumatic cylinder 40, switch the pneumatic cylinder 40 back and forth. It consists of a direction change valve (SV) that controls to move.
    [23] A guide rail 70 installed in parallel with the pneumatic cylinder 40 inside the cover frame 30, and linearly moved back and forth by the guide rail 70, and sliding connected to an upper end of the partition door 60. It consists of blocks 72 and 74.
    [24] The pneumatic cylinder 40 is, for example, a rodless cylinder consisting of a cylinder tube 42 fixed to the inside of the cover frame 30 and a cylinder block 44 connected to the sliding blocks 72 and 74. Can be configured.
    [25] The directional valve (SV) is composed of a five-port two-switched valve in which the port is switched by both solenoids (SL1) (SL2),
    [26] In the drawings, reference numerals M1 and M2 denote silencers installed in the discharge port of the directional valve SV, and RV1 and RV2 are installed in respective ports of the pneumatic cylinder 40 to indicate relief valves for adjusting the flow rate. LS1 and LS2 represent proximity switches used to detect a stop position of the pneumatic cylinder 40 and determine a time point for the control device to cut off the excitation current flowing to the solenoid SL2 and SL2. It shows a magnet installed in the cylinder block 44 of the pneumatic cylinder 30 for the detection of the switches (LS1) (LS2).
    [27] Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.
    [28] As shown in FIG. 7, when the driving current flows to one of the solenoids SL2 and SL2 of both of the solenoids SL2 and SL2, the direction switching valve SV is switched and the pneumatic cylinder 40 is switched. The flow path flowing through) is changed, and at the same time, the pneumatic cylinder 40 is linearly moved forward and backward.
    [29] At this time, as shown in Figures 1 to 6, the pneumatic cylinder 40 is configured as a rodless cylinder, and the direction switching valve SV is switched to the direction in which the partition door 60 is closed. When the block 44 moves to the front side, the sliding blocks 72 and 74 and the partition door 60 connected to the cylinder block 44 linearly move forward together, between both spindles 20 and 22. Will block.
    [30] During the operation as described above, the sliding blocks 72 and 74 serve to further stabilize the linear motion of the partition door 60 while receiving a linear guide of the guide rail 70 installed in the cover frame 30. The door 60 is linearly stabilized more stably without shaking by the door guides 50 and 52 located at both edge portions thereof.
    [31] At this time, when the pneumatic cylinder 40 reaches the front end portion, the closing of the partition door 60 is detected while the magnet 80 installed in the cylinder block 44 approaches the proximity switch LS1, and this signal is detected. The current flowing into the solenoid SL2 of the direction change valve SV is cut off through the input port of the control device so that the solenoid SL2 is in the non-excited state, and the partition door 60 is kept closed. .
    [32] On the other hand, when the direction change valve (SV) is switched in the direction of opening the partition door 60, the cylinder block 44 of the rodless cylinder is moved to the rear side, the sliding block 72 is connected to the cylinder block 44 74 and the partition door 60 are linearly moved to the rear side together to open between the two spindles (20, 22).
    [33] During the operation as described above, the sliding blocks 72 and 74 serve to further stabilize the linear motion of the partition door 60 while receiving a linear guide of the guide rail 70 installed in the cover frame 30. The door 60 is linearly stabilized more stably without shaking by the door guides 50 and 52 located at both edge portions thereof.
    [34] At this time, when the pneumatic cylinder 40 reaches the rear end portion, the opening of the partition door 60 is detected as the magnet 80 installed in the cylinder block 44 approaches the proximity switch LS2, and this signal is detected. The current flowing through the solenoid SL1 of the diverter valve SV is cut off through another input port of the control device so that the solenoid SL1 is in an unexcited state, and the partition door 60 remains open. Done.
    [35] Then, when the relief valves RV1 and RV2 provided on the flow path from the direction switching valve SV to the pneumatic cylinder 40 are adjusted, the partition door 60 opens and closes individually. It can be set.
    [36] As described above, the present invention uses a pneumatic cylinder and a partition door to block the work space inside the machine formed by both spindles from side to side. Even when using a device that automatically loads / unloads a workpiece such as a gantry loader, it is possible to prevent a malfunction because it does not affect each other, even if it is blocked using a partition door. If the partition door is blocked even by manually removing the workpiece, it is possible to protect the operator from safety accidents, and the continuous operation of the machine is possible to improve the productivity.
