[0034] like Figure 1-8 As shown, a machine tool spindle claw seat disassembly tool of an embodiment of the utility model includes a pull rod 1, a first connecting head 11 is provided at the first end of the pull rod 1, and a first external thread 111 is provided on the first connecting head 11 to cooperate with the first internal thread of the spindle claw seat 5. The pull rod 1 is connected to the spindle claw seat 5 through the first connecting head 11.

[0035] When the spindle claw seat 5 needs to be pulled out, Figure 6 As shown, first extend the first connector 11 of the pull rod 1 into the bottom of the main shaft clamping cone hole, then rotate the pull rod 1 to connect the first external thread 111 with the first internal thread, and then manually or manually connect the rotating pull rod 1 with the telescopic rod of the cylinder, as shown in FIG. Figure 7-8 As shown, the spindle claw seat 5 is pulled out.

[0036] After the spindle claw seat 5 is pulled out, the pull rod 1 is rotated in the opposite direction to separate the pull rod 1 from the spindle claw seat 5 .

[0037] A machine tool spindle claw seat disassembly tool according to an embodiment of the utility model fully utilizes the first internal thread in the spindle claw seat 5. The machine tool spindle claw seat disassembly tool according to an embodiment of the utility model is easy to disassemble and has high efficiency. In actual applications, the spindle claw seat 5 can be disassembled in 3 minutes.

[0038] The machine tool spindle claw seat disassembly tool of the utility model embodiment has strong versatility. The machining center has only two types of spindles, HSK-A100 and HSK-A63. Two sets of special tools can be used for all machine tools.

[0039] like Figure 1 As shown, in a preferred embodiment of the present utility model, it also includes an anti-rotation sleeve 2 and at least one first handle rod 3.

[0040] The anti-rotation sleeve 2 is sleeved on the outside of the pull rod 1, and the pull rod 1 can rotate relative to the anti-rotation sleeve 2. The first end of the anti-rotation sleeve 2 is used to connect with the boss 51 of the spindle claw seat 5. The first handle rod 3 is vertically fixed to the second end of the anti-rotation sleeve 2. The anti-rotation sleeve 2 and the first handle rod 3 are configured to prevent the spindle claw seat 5 from rotating when the pull rod 1 is connected to the spindle claw seat 5.

[0041] When the first connector 11 is rotationally connected with the spindle claw seat 5, the spindle claw seat 5 rotates along with the first connector 11, so that the connection between the pull rod 1 and the spindle claw seat 5 cannot be achieved. Therefore, the first end of the anti-rotation sleeve 2 is connected to the boss 51 of the spindle claw seat 5, so that when the first connector 11 is rotationally connected with the spindle claw seat 5, the spindle claw seat 5 is prevented from rotating along with the first connector 11 by holding the first handle bar 3, thereby achieving the connection between the pull rod 1 and the spindle claw seat 5.

[0042] like Figure 1 As shown, in a preferred embodiment of the present utility model, the anti-rotation sleeve 2 includes a barrel 21 and a second connector 22 fixedly connected to a first end of the barrel 21 .

[0043] One end of the second connector 22 is provided with a plurality of grooves 221 corresponding to the bosses 51 of the spindle claw seat 5 . When the first connector 11 is connected to the spindle claw seat 5 , the grooves 221 and the bosses 51 are plugged into place.

[0044] like Figure 1 , 2 As shown in FIG. 5 , in a preferred embodiment of the present utility model, the second connecting head 22 includes a circular wall plate 222 and an annular wall plate 223 .

[0045] The center of the circular wall plate 222 is fixed to the first end of the barrel 21 , one end of the annular wall plate 223 is fixed to the circular wall plate 222 , and the annular wall plate 223 surrounds the first connector 11 , and the groove 221 is located at the other end of the annular wall plate 223 .

[0046] like Figure 1 , 2As shown in Figures 6 and 7, in a preferred embodiment of the present utility model, the spindle claw seat 5 and the spindle clamping cone hole have the same center, the diameter of the annular wall plate 223 is the same as the diameter of the spindle claw seat 5, and the annular wall plate 223 and the first connecting head 11 also have the same center.

[0047] In a preferred embodiment of the present invention, the circular wall plate 222 is connected to the barrel 21 by threads or welding.

[0048] For example, a threaded hole is provided at the center of the circular wall plate 222 , an external thread is provided at the first end of the barrel body 21 , and the circular wall plate 222 is fixedly connected to the external thread at the first end of the barrel body 21 through the threaded hole.

[0049] like Figure 1 , 2 As shown, in a preferred embodiment of the utility model, a second external thread 12 is provided on the pull rod 1, and a second internal thread 21 cooperating with the second external thread 12 is provided on the inner wall of the anti-rotation sleeve 2, so as to prevent the anti-rotation sleeve 2 from shaking radially relative to the pull rod 1, ensure that the anti-rotation sleeve 2 and the pull rod 1 have the same center, and prevent the anti-rotation sleeve 2 from shaking to cause a situation that is not conducive to the connection with the main shaft claw seat 5.

[0050] like Figure 1 As shown, in a preferred embodiment of the present utility model, the number of the first handle bars 3 is two, and the two first handle bars 3 are respectively fixed to the two sides of the anti-rotation sleeve 2 to achieve two-handed holding and improve the anti-rotation effect.

[0051] like Figure 1 As shown, in a preferred embodiment of the utility model, it also includes a second handle bar 4, which is vertically arranged on the second end of the pull rod 1. The operator rotates the pull rod 1 and applies tension to the pull rod 1 by holding the second handle bar 4.

[0052] like Figure 3 As shown, in a preferred embodiment of the utility model, a through hole is opened at the second end of the pull rod 1, and the second handle rod 4 is detachably inserted into the through hole. For example, when the pull rod 1 is separated from or sleeved with the anti-rotation sleeve 2, the second handle rod 4 needs to be separated from the pull rod 1. After the anti-rotation sleeve 2 is removed or installed, the second handle rod 4 is installed on the pull rod 1.
