[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a four-axis turntable for a CNC machine tool, comprising:

[0023] A CNC machine tool body 1, a turntable body 7 is arranged above the CNC machine tool body 1;

[0024] An adjustment component includes a support plate 3, an adjustment plate 6, an arc plate 8, a rack 10 and a gear 13. The support plate 3 is arranged above the CNC machine tool body 1. A cylinder 2 is installed on the CNC machine tool body 1. The output end of the cylinder 2 is fixedly arranged at the bottom of the support plate 3. The cylinder 2 can drive the turntable body 7 to adjust the height through the support plate 3. A fixed plate 4 is fixedly arranged on one side of the support plate 3. Two damping shafts 5 are fixedly arranged at the outer end of the bottom of the fixed plate 4. The other ends of the two damping shafts 5 are fixedly arranged at one end of the bottom of the adjustment plate 6. The turntable body 7 is fixedly installed on the adjustment plate 6;

[0025] The two damping shafts 5 can make the adjustment plate 6 rotate at the outer end of the fixed plate 4. The two damping shafts 5 can also play a buffering role for the adjustment plate 6 to prevent the adjustment plate 6 from falling down and damaging the gear 13. The fixed plate 4 is provided so that there is a certain gap between the adjustment plate 6 and the support plate 3, so that the adjustment plate 6 can be adjusted to a vertical state;

[0026] The arc plate 8 is fixedly arranged at the bottom of the adjustment plate 6, and a through hole 9 is penetrated on the support plate 3. The arc plate 8 is slidably arranged through the through hole 9, and the inner top of the through hole 9 is arranged in an arc surface. The arc plate 8 is slidably arranged against the top and both sides of the through hole 9, thereby improving stability;

[0027] The rack 10 is fixedly arranged on the outer side of the arc plate 8, and the rack 10 is arranged in an arc shape. A shaft 12 is rotatably arranged on the inner wall of the through hole 9. The other end of the shaft 12 penetrates one side of the support plate 3 and is rotatably arranged. The shaft 12 penetrates the gear 13 and is fixedly arranged. The rack 10 is meshed and connected with the gear 13, so that the rotation of the gear 13 can drive the rack 10 to move. Limit blocks 11 are fixedly arranged at both ends of the rack 10. The two limit blocks 11 are both arranged in cooperation with the gear 13. The two limit blocks 11 both play a role of limiting the adjustment plate 6. When the two limit blocks 11 are respectively against the gear 13, the adjustment plate 6 is in a vertical state and a horizontal state respectively.

[0028] A crank 14 is fixedly provided on the outer side of the shaft 12, and a latch 15 is slidably provided on the crank 14. A latch hole is provided on one side of the support plate 3, and the latch 15 is matched with the latch hole. When the rack 10 is rotated to the ends of both ends by the crank 14, the latch 15 can be just inserted into the latch hole.

[0029] The detailed working process of the utility model is as follows:

[0030] 1. When adjusting to the vertical state, the staff first pulls out the latch 15, then turns the crank 14 counterclockwise to drive the shaft 12 to rotate, the shaft 12 drives the rack 10 to rotate through the gear 13, and the rack 10 drives the adjustment plate 6 to rotate downward through the arc plate 8. When the limit block 11 at one end clamps the gear 13, the latch 15 is inserted back into the clamping hole to adjust the turntable body 7 to the vertical state;

[0031] 2. When adjusting to the horizontal state, the staff first pulls out the pin 15, then turns the crank 14 clockwise to drive the adjustment plate 6 to rotate upward. When the limit block 11 at the other end clamps the gear 13, the pin 15 is inserted back into the clamping hole to adjust the turntable body 7 to the horizontal state.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
