[0026] like Figure 1 to Figure 5As shown, an embodiment of the utility model proposes a square hole shaft positioning groove milling tool, including a fixed seat 1 and a shaft 3, a slot is opened in the center of one side wall of the fixed seat 1, one end of the shaft 3 is inserted into the inner wall of the slot, and four groups of positioning grooves 16 are evenly opened on the outer wall of the shaft 3, and four groups of slots intersecting with the slot are opened on the fixed seat 1, and a limiting block 15 is slidably arranged in the slot, and one end of the limiting block 15 is clamped on the inner wall of the positioning groove 16. The shaft 3 in the slot can be positioned by the set limiting block 15, and the shaft 3 can be evenly stressed during operation by evenly arranging four groups of positioning grooves 16 and the limiting block 15 on the shaft 3.

[0027] Specifically, the limit block 15 is fixedly connected to the guide column 12 on the outer wall of the slot side, and a buffer cavity is arranged on the inner wall of the guide column 12, in which a buffer block is slidably connected, and one end of the buffer block is connected to the buffer cavity through a second spring 13. The guide block 11 and the slide rod 14 can move up and down through the provided buffer block and the second spring 13. After the sleeve 2 slides out of the outside of the slot, the guide block 11 will pop out of the slot under the elastic force recovery of the second spring 13, so as to facilitate the removal of the limit block 15, thereby disassembling and replacing the shaft 3. The four groups of slots and the guide rod 5 are staggered, and the guide block 11 cannot pop out of the slot.

[0028] Specifically, the other end of the buffer block is fixedly connected to a slide rod 14, one end of the slide rod 14 extends out of the buffer cavity and is installed with a guide block 11, and the slide rod 14 and the guide block 11 are extended and retracted to drive the limit block 15 at one end of the guide column 12 to move.

[0029] Specifically, a sleeve 2 is provided on the outside of the guide block 11, and the sleeve 2 is slidably set on the outer wall of the fixed seat 1, and two groups of guide rods 5 are symmetrically connected to one side wall of the sleeve 2. The four groups of guide blocks 11 in the slot can be compressed and limited by the set sleeve 2, so that the limit block 15 can be fixed, so that the shaft 3 can work stably. When it is necessary to release the fixation of the shaft 3, the four groups of guide blocks 11 can be ejected at the same time by sliding the sleeve 2. At this time, it is only necessary to pull the limit blocks 15 one by one to disengage from the positioning groove 16.

[0030] Specifically, two groups of guide seats 4 are symmetrically arranged on the outer wall of the fixing seat 1 , one end of the guide rod 5 extends into the guide groove arranged on the inner wall of the guide seat 4 , and the sliding of the guide rod 5 in the guide seat 4 can support the stable movement of the sleeve 2 .

[0031] Specifically, the inner wall of the guide groove is fixedly installed by a first spring 7, one end of the first spring 7 is fixedly connected to the inner wall of the guide rod 5, and a slider 8 is fixedly connected to the outer wall of one end of the guide rod 5. The slider 8 is slidably set in the slide groove 9, and the slide groove 9 is set on one side of the guide groove. When the locking column 10 is taken out, the guide rod 5 can be driven to one side by the elastic force of the first spring 7, and the sliding between the set slider 8 and the slide groove 9 can support the stable sliding of the guide rod 5 and play a role of limiting at the same time.

[0032] Specifically, a locking column 10 is threadedly connected to the inner wall of the guide rod 5, and one end of the locking column 10 passes through the guide seat 4 and is fixedly connected to the knob 6. The guide rod 5 can be fixed by the set locking column 10. When the shaft 3 needs to be removed, the locking column 10 can be driven to be screwed out by the knob 6. At this time, with the cooperation of the elastic force of the first spring 7 and the second spring 13, the shaft 3 can be conveniently replaced.

[0033] Working principle: The axis 3 in the slot can be positioned by the limit block 15, and the axis 3 can be evenly stressed during operation by evenly arranging four groups of positioning slots 16 and the limit block 15 on the axis 3. The guide block 11 and the slide bar 14 can move up and down by the buffer block and the second spring 13. After the sleeve 2 slides out of the slot, the guide block 11 will pop out of the slot under the elastic force of the second spring 13, so that the limit block 15 can be taken out, thereby disassembling and replacing the axis 3. The four groups of guide blocks in the slot can be adjusted by the sleeve 2. 11 is compressed and limited, so that the limit block 15 can be fixed, so that the shaft 3 can work stably. When it is necessary to release the fixation of the shaft 3, the four groups of guide blocks 11 can be ejected at the same time by sliding the sleeve 2. At this time, it is only necessary to pull the limit blocks 15 out of the positioning groove 16 one by one, and the locking column 10 can be driven out by the knob 6. When the locking column 10 is taken out, the elastic force of the first spring 7 can drive the guide rod 5 to bounce to one side, and the sliding between the slider 8 and the slide groove 9 is provided to support the guide rod 5 to slide stably, and at the same time play a role of limiting.
