[0001] The present application relates to the field of machinery, and in particular to a CNC machine tool for milling, drilling and tapping of cylindrical parts and a chuck seat assembly thereof. Background Art

[0002] The motor base is a cylindrical part. When processing the motor base, it is necessary to process the end face and the outer periphery of the motor base. The motor base is flipped by the flip mechanism 1 on the CNC machine tool. Figure 1 The flip mechanism 1 in the related art includes a flap 11 and connecting plates 12 at both ends of the flap 11. The two ends of the connecting plate 12 are used to be rotatably connected to the machine tool, and the machine tool is provided with a flip motor that drives the connecting plate 12 to rotate; a first internal expansion chuck 14 is rotatably provided on the flap 11, and a driving motor that drives the first internal expansion chuck 14 to rotate is provided on the side of the flap away from the motor base. When in use, the motor base is fixed by the first internal expansion chuck 14, the flip motor drives the flap 11 to rotate, thereby processing the side wall of the motor base, and the driving motor drives the first internal expansion chuck 14 to rotate, so that the circumferential side wall of the motor base is processed.

[0003] However, the above-mentioned turning mechanism 1 is only convenient for processing the outer periphery and one end face of the motor base, and the other end face needs to be additionally processed, resulting in low processing efficiency. Utility Model Content

[0004] In order to facilitate all-round processing of the outer peripheral wall of a motor base, the present application provides a CNC machine tool for full-sequence processing of milling, drilling and tapping of cylindrical parts and a chuck seat assembly thereof.

[0005] In the first aspect, the present application provides a chuck seat assembly, which adopts the following technical solution:

[0006] The chuck seat assembly includes a flipping mechanism, which includes a flap and connecting plates at both ends of the flap, and the flap is provided with a first inward-expanding chuck for fixing the motor base; it also includes a slide rail and a side-end positioning and rotating mechanism slidably connected to the slide rail, the side-end positioning and rotating mechanism is arranged on one side of the flipping mechanism, and the sliding direction of the side-end positioning and rotating mechanism is a direction away from or close to the flipping mechanism, and the first inward-expanding chuck flips in a direction close to or away from the side-end positioning and rotating mechanism; the side-end positioning and rotating mechanism includes a sliding seat and a second inward-expanding chuck rotatably arranged on the sliding seat, the second inward-expanding chuck is horizontally facing the flipping mechanism, and the second inward-expanding chuck is used to clamp the end of the motor base away from the flap; a processing hole is opened through the flap, and the processing hole is opposite to the area of ​​the end face of the motor base that needs to be processed.

[0007] By adopting the above technical solution, during processing, the motor base is fixed to the flap by the first internal expansion chuck, at which time the axis of the motor base is in the vertical direction, the milling and drilling mechanism is located at the top of the motor base, and the milling and drilling mechanism processes the motor base. When processing the end of the motor base close to the flap, the flap is rotated upward, and the milling and drilling mechanism passes through the processing hole to process the motor base, thereby realizing the processing of both ends of the motor base.

[0008] When processing the side wall of the motor base, the first internal expansion chuck flips toward or away from the side end positioning rotation mechanism until the axis of the motor base is horizontal, and the second internal expansion chuck slides along the slide rail into the motor base and clamps the motor base. The milling, drilling and tapping mechanism processes the side wall of the motor base. When the direction of the side wall needs to be changed, the first internal expansion chuck releases the motor base, and the second internal expansion chuck fixes the motor base and rotates, thereby changing the angle of the side wall of the motor base, which is convenient for all-round processing of the side wall of the motor base. In this application scheme, both ends and circumferential side walls of the motor base can be processed, thereby realizing full-sequence processing, without the need for step-by-step or machine tool processing, making processing convenient, improving processing efficiency, and reducing production costs.

[0009] During processing, both ends of the motor base are rigidly and stably supported by the second internal expansion chuck and the first internal expansion chuck, so that the motor base is stable during processing; at the same time, the force strength of the first internal expansion chuck is also reduced, reducing the possibility of damage to the first internal expansion chuck.

[0010] Optionally, a reduction gearbox is fixed on the sliding seat, a numerically controlled motor is connected to the input end of the reduction gearbox, and an output end of the reduction gearbox is connected to the second internal expansion chuck.

[0011] By adopting the above technical solution and setting the reduction box, it is convenient to adjust the rotation speed of the second internal expansion chuck, and it is also convenient to install the numerical control motor.

[0012] Optionally, a stepped limiting ring groove is provided on the flap, the first internal expansion chuck is provided at the center of the stepped limiting ring groove, and the stepped limiting ring groove limits the end of the motor base.

[0013] By adopting the above technical solution, the stepped limiting ring groove positions the motor base, making the motor base more stable during processing.

[0014] In the second aspect, the present application provides a CNC machine tool for milling, drilling and tapping of cylindrical parts, which adopts the following technical solution:

[0015] A CNC machine tool for full-sequence milling, drilling and tapping of cylindrical parts, comprising a machine tool body and the above-mentioned chuck seat assembly, the machine tool body comprising a base and a milling, drilling and tapping mechanism arranged on the top of the base; the flip mechanism is arranged on the base, and the flip mechanism is located below the milling, drilling and tapping mechanism; the sides of two connecting plates facing away from each other are rotatably connected to the base, the base is provided with a slide groove, the slide groove is located at the bottom of the flip plate, the slide rail is arranged in the slide groove, and the side end positioning and rotating mechanism is slidably connected to the slide rail.

[0016] By adopting the above technical scheme, the milling, drilling and tapping mechanisms are located above the flipping mechanism, which fixes the motor base and can flip and adjust the side wall of the motor base to facilitate processing. When the side end positioning mechanism flips the motor base to a horizontal direction with the axis, the second internal expansion chuck clamps the motor base. After the second internal expansion chuck is rotated, the direction of the motor base can be adjusted, which facilitates the processing of the circumferential side walls and end faces of the motor base, allowing the CNC machine tool to easily realize full-sequence processing.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. The setting of the second internal expansion chuck facilitates all-round processing of the side wall of the motor base and realizes full-sequence processing without step-by-step or machine tool processing, making processing convenient, improving processing efficiency and reducing production costs;

[0019] 2. During processing, the two ends of the motor base are rigidly and stably supported by the second internal expansion chuck and the first internal expansion chuck, so that the motor base is stable during processing; at the same time, the force strength of the first internal expansion chuck is also reduced, reducing the possibility of damage to the first internal expansion chuck; BRIEF DESCRIPTION OF THE DRAWINGS

Figure 2 The chuck seat assembly includes a flipping mechanism 1, a side end positioning and rotating mechanism 2 and a slide rail 3. The flipping mechanism 1 includes a flap 11 and connecting plates 12 at both ends of the flap 11. When the flap 11 is in a horizontal direction, the connecting plates 12 at both ends of the flap 11 are fixed to the top surface of the flap 11, the two connecting plates 12 are parallel to each other, and the two connecting plates 12 are in a vertical direction. A limiting plate 13 is fixed to the top surface of the flap 11, and a plurality of concentrically arranged stepped limiting ring grooves 131 are provided on the limiting plate 13. The thickness of the limiting plate 13 located at the center of the stepped limiting ring groove 131 is the thickest. The stepped limiting ring groove 131 is snapped into the end of the motor base to form a positioning. A first internal expansion chuck 14 for fixing the motor base is installed at the center of the limiting plate 13, and the two opposite sides of the connecting plate 12 are rotatably connected to the machine tool, and the connecting plate 12 is driven to rotate by the motor.

At this time, the two ends of the motor base are fixed, making the processing stable. When the circumferential outer wall of the motor base is to be processed, the first internal expansion chuck 14 is loosened, and the second internal expansion chuck 24 rotates to drive the motor base to rotate the set angle, which is convenient for the full sequence processing of the second internal expansion chuck 24.
