[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] Reference Figures 1 to 4 As shown, a high-stability turning-milling compound machine tool comprises a machine tool body 1 and a support and adjustment mechanism arranged at the bottom of the machine tool body 1;

[0024] The support adjustment mechanism includes four support plates 2 respectively fixed to the four corners of the bottom of the machine tool body 1, a double-sided screw 6 arranged below the support plate 2, a support seat 10 arranged below the double-sided screw 6, and a bottom plate 4 arranged below the support seat 10, a support block 5 is fixed to one side of the top surface of the support seat 10, one end of the double-sided screw 6 is rotatably connected to the side wall of the support block 5, and both sides of the double-sided screw 6 are threadedly connected with a moving block 9, the bottom surface of the moving block 9 is slidably connected to the top surface of the support seat 10, and multiple groups of inclined connecting rods 7 are hinged between the moving block 9 and the support plate 2;

[0025] The two sides of the support seat 10 are respectively slidably connected with the auxiliary support block 3, the bottom of the auxiliary support block 3 is fixed to the bottom plate 4, and a buffer cylinder and a spring are arranged at a position inside the auxiliary support block 3 between the bottom plate 4 and the support seat 10. A buffer cylinder and a buffer spring are arranged between the bottom plate 4 and the support seat 10;

[0026] Through the setting of the support adjustment mechanism, when it is necessary to adjust the height of the four corners of the bottom of the machine tool, the double-sided screw 6 can be rotated, causing the two moving blocks 9 to extend the rod body of the double-sided screw 6 to move relative to or away from each other under the restriction of the support seat 10, and then the connecting rod 7 is pushed by the moving block 9 to push the support plate 2 up or down, and the buffer cylinder and spring under the moving block 9 can reduce the shock of the turning and milling compound machine tool during use, making the turning and milling compound machine tool more stable when used.

[0027] But in reality, it requires the cooperation of two people. One person squats down and turns the turntable at the bottom of the lathe to adjust the height of the four corners of the machine tool, and the other person stands in front of the machine tool to observe whether the machine tool is tilted during the adjustment process, which then causes the problem of labor waste.

[0028] In view of this, in order to solve the above problem, a linkage mechanism is provided on the other side of the top surface of the support seat 10 for personnel to easily rotate the double-sided screw 6.

[0029] The linkage mechanism includes a rectangular block 15 fixed to the other side of the top surface of the support seat 10, one side of the rectangular block 15 is in contact with the surface of the machine tool body 1, and a rectangular groove is provided on the other side of the rectangular block 15. The double-sided screw 6 rotates and penetrates into the bottom of the inner side of the rectangular groove and is tightly sleeved with a gear 11. A rotating shaft located above the gear 11 is vertically fixed on the inner wall of the innermost side of the rectangular groove, and a gear 2 12 is rotatably sleeved on the rotating shaft. A metal hinge 17 is transmission-connected between the gear 11 and the gear 2 12, and a handle is provided on the edge of the gear 2 12 away from the machine tool body 1;

[0030] Through the setting of the linkage mechanism, when it is necessary to rotate the double-sided screw 6 to adjust the height of the machine tool body 1, the handle can be turned to drive gear 2 12, and the gear 1 11 can be driven to rotate synchronously through the support seat 10, and then the double-sided screw 6 can be driven to rotate synchronously, causing the two locking blocks 16 on the rod body of the double-sided screw 6 to move relative to or away from each other. In this way, it can replace the operating method in the prior art that requires two people to cooperate, one person squats and rotates the turntable at the bottom of the lathe to adjust the height of the four corners of the machine tool, and the other person stands in front of the machine tool during the adjustment process to observe whether the machine tool is tilted.

[0031] After the machine tool was used for a period of time, it was found that the handle was set too high, causing the operator to accidentally touch the handle when operating the machine tool, which in turn drove gear 2 12, causing the double-sided screw 6 to rotate and causing the machine tool body 1 to tilt.

[0032] Therefore, in order to solve the above problem, a locking component is provided on one side of the rod body of the double-sided screw 6.

[0033] Reference Figure 3 As shown, it is worth noting that the locking component includes a gear three 13 that is tightly sleeved on the rod body of the double-sided screw 6, a gear one 11 that is L-shaped and inclined on one side of the gear three 13, and a small rectangular bottom plate 8 that is arranged below the gear one 11. The small rectangular bottom plate 8 is fixed to one side of the bottom plate 4, one end of the gear one 11 is embedded between two adjacent teeth of the gear three 13, and the other end of the gear one 11 is vertically fixed with a gear two 12. Fixed blocks 14 are respectively arranged on both sides of the gear two 12, and the fixed blocks 14 are fixed to the top surface of the small rectangular bottom plate 8. A support shaft is rotatably connected between the two fixed blocks 14, and the support shaft rotates through the gear two 12;

[0034] A spring is fixed to the bottom surface of the gear 2 12 , and the end of the spring is fixed to the top surface of the small rectangular bottom plate 8 .

[0035] By setting the locking component, when it is necessary to adjust the height of the machine tool body 1, the gear 1 1 is driven to rotate with the support shaft on the fixed block 14 as the axis by stepping on the gear 2 12. During this process, the spring under the gear 2 12 is compressed, and one end of the gear 1 11 is disengaged from between the two teeth of the gear 3 13, and then the lock of the gear 1 1 on the gear 3 13 is released. After the height of the machine tool body 1 is adjusted, the gear 2 12 is released, and the reverse elastic force of the spring is used to push the gear 2 12 up. One end of the gear 2 12 is restricted by the support shaft and rotates along the support shaft, and drives one end of the gear 1 11 to be re-embedded between the two teeth of the gear 3 13. In this way, the double-sided screw 6 can be locked by the cooperation of the gear 1 11 and the gear 3 13.
