Description

Technical Field

[0001] The utility model relates to a cutting machine tool, in particular to a drilling and cutting machine tool. Background Art

[0002] Machine tools can be divided into general-purpose and special-purpose machine tools. General-purpose machine tools are capable of processing a wide range of workpieces, while special-purpose machine tools are designed specifically for machining specific workpieces. Drilling machines are a type of general-purpose machine tool used to drill holes in workpieces. When a workpiece has a large number of holes, machining efficiency is low, and repeated clamping of the workpiece inevitably leads to accumulated errors, affecting the quality of the workpiece.

[0003] Therefore, it is necessary to design a special machine tool for drilling disc-shaped parts. Utility Model Content

[0021] The following is combined with Figure 1 To the attached Figure 4 The principles and features of the present invention are described, and the examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] A drilling and cutting machine tool comprises a first cutting mechanism 1, a second cutting mechanism 2, a spindle assembly 3 and a fourth bracket 5.

[0023] The first cutting mechanism 1 includes a first drill 101, and the second cutting mechanism 2 includes a second drill 201. The first drill 101 can move in three mutually perpendicular directions in space, and the second drill 201 can move in three mutually perpendicular directions in space. The first drill 101 and the second drill 102 are cutting terminals consisting of a motor and a drill bit, and are used to drill holes in a workpiece.

[0024] Refer to the attached Figure 1 , defining the Y direction as the first direction, the Z direction as the second direction, and the X direction as the third direction. The first cutting mechanism 1 further includes a first bracket 102, a first slide 103, a second slide 104, and a third slide 105. The first slide 103 is slidably connected to the first bracket 102 and slides along the first direction; the second slide 104 is slidably connected to the first slide 103 and slides along the second direction; and the third slide 105 is slidably connected to the second slide 104 and slides along the third direction. The second cutting mechanism 2 includes a second bracket 202, a fourth slide 203, a fifth slide 204 and a sixth slide 205; the fourth slide 203 is slidably connected to the second bracket 202, the fourth slide 203 slides along the third direction, the fifth slide 204 is slidably connected to the fourth slide 203, the fifth slide 204 slides along the first direction, the sixth slide 205 is slidably connected to the fifth slide 204, and the sixth slide 205 slides along the second direction; the second drilling rig 201 is fixed to the sixth slide 205. The sliding mode and driving mode of the first slide 103, the second slide 104, the third slide 105, the fourth slide 203, the fifth slide 204 and the sixth slide 205 are all consistent. The sliding mode is achieved by the cooperation of the guide rail and the slider; the driving mode is achieved by the cooperation of the motor, the lead screw and the slider. This implementation method is a common technical method in this field and will not be repeated here.

[0025] The spindle assembly 3 includes a spindle body 301 and a fixture 302 for securing the workpiece 4. The fixture is a conventional three-jaw chuck, attached to the upper end of the spindle body 301. The spindle body 301 is rotatably connected to the fourth bracket 5. A synchronous pulley is attached to the spindle body 301, which is driven by a motor and a synchronous belt to rotate the spindle body 301.

[0026] The first and second drilling machines can be moved to the upper and lower positions of the workpiece 4, respectively, to perform machining operations. Therefore, this solution is suitable for drilling disc-type parts (such as brake discs), as all holes can be machined in a single clamping operation. This improves machining efficiency while also avoiding machining errors caused by repeated clamping.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
