DETAILED DESCRIPTION

[0027] The following will refer to the attached Figure 1 To the attached Figure 6 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

In detail, a first ball screw 16 is installed on the support frame 11, and the rotating disk 12 is installed on the first ball screw 16. First slide rails 15 for use with the rotating disk 12 are provided on both sides of the first ball screw 16.

[0029] The rotating disk 12 and the second drive base 13 are rotatably engaged. An arcuate rack 121 is fixedly connected to the edge of the rotating disk 12. A transmission gear 171 is mounted on the side of the second drive base 13 facing the rotating disk 12 and meshes with the arcuate rack 121. A driver 17 is fixedly connected to the second drive base 13 and is in driving connection with the transmission gear 171. Specifically, a support shaft is provided in the middle of the rotating disk 12, and the second drive base 13 is rotatably mounted on the support shaft to control the position of the second drive base 13.

[0030] A first sliding seat 14 slidably engages with the second drive seat 13, allowing it to slide along the length of the second drive seat 13. A clamp 141 is mounted on the first sliding seat 14. The second drive seat 13 is also equipped with a motor 142, which is connected to the clamp 141. Once the drill bit is clamped in the clamp 141, the motor 142 drives the drill bit to rotate. A gun drill guide sleeve 104, corresponding to the clamp 141, is mounted on the side of the second drive seat 13 facing away from the rotating disk 12. This sleeve ensures a horizontal turntable for long drill bits, improving their stability.

[0031] A second ball screw 103 is mounted on the second driving seat 13 , and the first sliding seat 14 is mounted on the second ball screw 103 . Second slide rails 106 for use with the first sliding seat 14 are provided on both sides of the second driving seat 13 .

[0032] The processing platform 3 includes a second sliding seat 31, a third sliding seat 32, and a positioning platform 33. The second sliding seat 31 slides along the length of the first drive seat 2, and the third sliding seat 32 slides along the length of the second sliding seat 31. The positioning platform 33 and the third sliding seat 32 rotate with each other. Specifically, the first drive seat 2 is equipped with a third ball screw 21 and two third slide rails 22 for use with the second sliding seat 31. The second sliding seat 31 is equipped with a fourth ball screw 311 and a fourth slide rail 312 for use with the third sliding seat 32. The third sliding seat 32 is equipped with a rotating shaft 321 for rotating the positioning platform 33. The ball screws are connected to a motor to drive their rotation, and the slide rails can reduce friction between the two objects.

[0033] Specifically, the second drive seat 13 can realize the switching between horizontal and vertical drilling and milling machine tools through the cooperation of the arc rack 121 on the rotating disk 12 and the transmission gear 171, integrating the functions of horizontal drilling and milling machine tools and vertical drilling and milling machine tools. Among them, the second drive seat 13 and the processing platform 3 can slide up and down, left and right, and rotate, thereby achieving the effect of six-axis drive, effectively improving the diversity of the use of drilling and milling machine tools, and can realize the drilling and milling machine tool to process any position and direction except the bottom of the workpiece, solving the problem that the workpiece needs to be switched between horizontal machine tools and vertical machine tools, and improving the processing efficiency of the workpiece.

[0034] Two groups of limiting units are provided on the side of the second drive seat 13 facing the rotating disk 12. The two groups of limiting units can better limit the second drive seat 13, accurately control the rotation angle of the second drive seat 13, and avoid the second drive seat 13 from rotating too much. The limiting unit includes a telescopic device 132, an articulated seat 133 and a limiting rod 134. The telescopic device 132 and the articulated seat 133 are both installed on the second drive seat 13, and the limiting rod 134 is installed on the articulated seat 133. One end of the limiting rod 134 is installed on the telescopic device 132, and one end of the limiting rod 134 is slidably matched with the telescopic device 132, and the other end of the limiting rod 134 corresponds to the rotating disk 12.

[0035] Specifically, after the second drive seat 13 rotates to a suitable angle, the telescopic device 132 pushes the limiting rod 134 to rotate, so that the limiting rod 134 contacts the rotating disk 12, thereby realizing the position limitation between the rotating disk 12 and the second drive seat 13.

[0036] Both sides of the limiting rod 134 are provided with a limit block 131 installed on the second drive seat 13, and the limit block 131 has a limit groove, and the rotating disk 12 corresponds to the limit groove. The setting of the limit block 131 can disperse the supporting strength of the support shaft and ensure the stability of the connection between the rotating disk 12 and the second drive seat 13.

[0037] Two symmetrically arranged guide frames 18 are installed above the support frame 11, and a guide wheel 181 is installed inside the guide frame 18. A counterweight block 183 is installed inside the support frame 11. A retractable belt 182 is wrapped around the guide wheel 181, and the two ends of the retractable belt 182 are fixedly connected to the rotating disk 12 and the counterweight block 183 respectively.

[0038] Specifically, during the lifting process of the second drive seat 13, the counterweight block 183 follows the lifting of the second drive seat 13 through the retractable belt 182 and the rotating disk 12, providing the necessary reverse force to the counterweight block 183 to ensure the stability and safety of the second drive seat 13 during operation.

[0039] Both sides of the first drive seat 2 are provided with a material guide groove 23, and a threaded chip removal device 24 is provided inside the material guide groove 23. Telescopic protective covers 313 are respectively installed between the two sides of the second sliding seat 31 and the first drive seat 2, and between the two sides of the third sliding seat 32 and the second sliding seat 31. In detail, the threaded chip removal device 24 includes a shaftless blade and a motor. The motor is fixed to the outside of the first drive seat 2, and the shaftless blade is located in the material guide groove 23 and is connected to the motor for transmission.
