New description: [New technical field] This is a machine tool spindle stop device that uses a driven chuck to engage the main shaft of the spindle to move the tool spindle stop device. By. [Prior Art] Press, there are quite a few machine tools with spindles, 1^ vertical machine, horizontal machine tool or gantry machine tool, vertical lathe, , ^ team car Che Qingyi - etc. In particular, lathe-type machine tools are frequently used in the operation of the spindle. Taking the stop application of the spindle in a vertical lathe as an example, a turning tool and a milling cutter are usually provided under the spindle in the moving machine. The clothes can be automatically and steadily switched, and the bed below the main shaft is used for placing the work pieces that are lost by the jig. When machining with a milling cutter, the main shaft drives the milling cutter to rotate and the bed is

In the traditional way, the DC motor that drives the spindle rotates the disc that is linked to the spindle to be positioned at an angle necessary for the turning of the turning tool. The piece holds the disk that is interlocked with the spindle to stop the disk together with the spindle. However, since the spindle that is interlocked with the turning tool is stopped, the workpiece on the lower side of the spindle is rotated by the turning tool. For turning, the relative force of the rotating workpiece on the turning tool will affect the disc that is linked with the spindle and the lower turning tool. Even if the brake plate is held and the disc is still slipping, the displacement of the turning tool under the spindle changes. A 4 M328921 cutting angle, which seriously affects the smoothness and precision of turning machining, needs to be improved. [New content] The spindle stop device of the creation tool machine comprises: a disc, which is interlocked with the tool-machine spindle, the disc plate is provided with a stop groove; and a latch device, which is arranged in the direction of the disc The latch body is pivotally embedded in the retaining groove of the disc; by the above configuration, the latch body on the latch can chuck the retaining slot on the disc, so that the disc can be completely accurate. Stopper. [Embodiment] The features of the present invention can be applied to various machine tools, but the description of the stoppage of the spindle in the vertical lathe (hereinafter referred to as the machine tool) is explained, please refer to the schematic of the first figure; The center vertical lathe has a disc bed 1 and has a door-shaped frame 2 on the back side of the bed 1 , and a stand 3 on the column 2 , and then stands on the rail 3 The spindle holder 4 is pivoted to the head 5 which can be displaced above and below the spindle holder 4. Referring to the second figure, the head 5 is provided with a spindle 52 driven by a DC motor 51, and the spindle 5 is provided with a stop device 6 of the present invention. Referring to the third figure, the embodiment of the present writing device 6 includes: a disc 6 1 which is substantially disk-shaped and interlocks with the main shaft 5 2 in the second figure, and corresponds to the circumferential diameter of the disc 6 1 The two ends are respectively provided with concave groove 6 1 1 and 6 1 2 on the upper and lower sides of the disk 6 1 ; the two latches 6 2 are respectively disposed at opposite ends of the circumferential diameter of the disk 6 1 Please refer to the fourth and fifth figures. Each of the latches 6 2 respectively has an upper base 621 and a lower base 631 at the upper and lower ends, and is divided into the corresponding discs 6 1 by M328921. a lower stop groove 6 1 1 , 6 1 2 ; a piston chamber 6 2 2 is disposed in the upper frame 6 2 1 , and a piston 6 2 3 is disposed in the piston chamber 6 2 2 , the piston β 2 3 faces the A disc body 6 24 having a square cross section is protruded from the disc 6 1 direction, and is pivotable to the outside of the piston chamber 62 2 and embedded in the retaining groove 611 above the disc 61, and further toward the disc 6 1 in a reverse direction, a piston rod 6 2 5 can be pivoted to the outside of the piston chamber 6 2 2; a piston chamber 633 is disposed in the lower base 63 1 , and a piston 633 is disposed in the piston 632. 633 protrudes toward the disk 6 1 in a direction a carcass 6 3 4 having a cross-section that can be pivoted outside the piston chamber 633 and embedded in the stop groove 6 below the disk 6 1 and protruded in the opposite direction of the disk 6 1 A piston rod 635 can be pivoted out of the piston chamber 633. When the spindle 52 in the second figure is to be stopped, since the DC motor 51 that drives the spindle 52 has the ability to accurately position the rotation angle, when the spindle 5 2 is to be stopped, such as the sixth and seventh. As shown in the figure, the locking groove 6 11 , 612 of the upper and lower ends of the corresponding diameter of the disk 6 1 and the base 621 of the second latch 62 and the lower body 63 1 of the lower base 63 can be precisely controlled. The cartridge body 6 34 corresponds to each other, so that the piston chamber 6 2 2 of the upper base 6 2 1 and the piston chamber 6 3 2 of the lower base 6 3 1 are respectively hydraulically supplied via the two latchers 6 2 , and the pistons 6 . 2 3, the piston 6 3 3 will be respectively pushed by the hydraulic pressure and respectively connected to the upper jaw body 6 2 4, the card body 6 3 4 respectively protrudes toward the piston chamber 6 2 2, the piston chamber 6 3 2, respectively The locking groove 6 1 1 above the disk 6 1 and the stopping groove 6 1 2 below the disk β i are engaged to cause the disk 61 to be stopped. M328921 In the creative feature provided by the present embodiment, since the disk 6 1 interlocked with the spindle 52 can be respectively driven by the hydraulic pressure on the two latches 6 2, the latch body 6 24, 6 3 4 card The retaining groove 6 1 1 and 612 on the upper side of the disk, so that the disk 61 can be completely accurately stopped, and the spindle 5 2 can be prevented from being received by the disk 6 1 by means of a conventional clamping method. The slippage effect can not be stopped, making the tool changer of the machine tool more convenient, stable and safe. Due to its practicability and special structure, it is neither found in the conventional tool machine spindle stop device nor before the application. , 1 提出 Propose a new type of patent application according to law. However, the above is only a preferred and feasible embodiment of the present invention, and the scope of the present invention cannot be limited by this, that is, the equivalent structural changes and modifications made by the applicant in accordance with the scope of the patent application and the content of the creation specification. All should remain within the scope of this creation patent. [Simple description of the diagram] The first figure shows a three-dimensional schematic diagram of a general vertical lathe.
