Description
Technical Field
[0001] This utility model relates to the field of CNC vertical drilling machine technology, specifically a rotary CNC vertical drilling machine. Background Technology
[0002] A drilling machine is a machine tool used to machine holes in solid materials. Drilling machines have a wide range of applications in the field of machining. They can process various materials, such as metals, wood, and plastics, and are used to manufacture various mechanical parts, molds, and fixtures. In the manufacture of many mechanical parts, it is necessary to machine multiple holes with precise positional relationships on the workpiece, where rotary CNC vertical drilling machines can demonstrate their advantages.
[0003] In existing rotary CNC vertical drilling machines, the operator places the part to be processed into a fixture of fixed size, and drills holes by rotating the bottom platform and continuously moving the drill bit downward. The two work together to perform drilling operations on the part.
[0004] Existing rotary CNC vertical drilling machines use fixed-size fixtures designed for workpieces within a specific size range. For workpieces exceeding this range, the fixtures cannot be well adapted, requiring constant disassembly and replacement of the fixtures during the processing of different workpieces. To address this, we propose a rotary CNC vertical drilling machine. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rotary CNC vertical drilling machine, including a base, a support frame on the upper surface of the base, a spindle box on the front side of the support frame, a drill bit rotatably connected to the bottom end of the spindle box, a sliding groove on the front side of the support frame, a support frame slidably connected inside the sliding groove, and a clamping mechanism.
[0007] Clamping mechanism: It includes a placement platform, guide groove, clamping block, rotating column, turntable, sliding hole and sliding column. The upper surface of the support frame is rotatably connected to the placement platform. The upper surface of the placement platform is provided with guide grooves. The inside of the guide grooves is slidably connected to the clamping block. The bottom end of the clamping block is fixedly connected to the sliding column. The bottom wall of the placement platform is rotatably connected to the rotating column. The top end of the rotating column is fixedly connected to the turntable. The upper surface of the turntable is provided with sliding holes. The inner wall of the sliding holes is slidably connected to the vertically adjacent sliding column to ensure the stability of the workpiece during processing. It can significantly reduce the clamping time of each workpiece, thereby improving the processing efficiency of the rotary CNC vertical drilling machine.
[0008] Furthermore, a microcontroller is provided on the left side of the support frame. The input terminal of the microcontroller is electrically connected to an external power source to provide electrical connections for various electrical appliances.
[0009] Furthermore, the clamping mechanism also includes a worm wheel and a worm. The worm wheel is fixedly sleeved on the outside of the rotating column, and the worm is rotatably connected to the inner wall of the placement platform. The worm wheel and the worm mesh with each other to achieve stable clamping.
[0010] Furthermore, a dial wheel is fixedly connected to one end of the worm gear extending outside the placement platform. The dial wheel is provided with evenly distributed anti-slip rods on its outside to facilitate adjustment of the clamping mechanism.
[0011] Furthermore, a toothed ring is fitted on the outer bottom of the placement platform, a motor is fixedly connected to the bottom of the support frame, a gear is fixedly connected to the top of the output shaft of the motor, the gear meshes with the toothed ring, and the input end of the motor is electrically connected to the output end of the microcontroller to realize the rotation of the workpiece.
[0012] Furthermore, an electric push rod is fixedly connected to the upper surface of the base. The telescopic end of the electric push rod is fixedly connected to the bottom end of the support frame, and the input end of the electric push rod is electrically connected to the output end of the microcontroller to realize the drilling of the parts.
[0013] Furthermore, it also includes a second motor, which is disposed on the upper surface of the spindle box. The bottom end of the output shaft of the second motor is fixedly connected to the top end of the drill bit, and the input end of the second motor is electrically connected to the output end of the microcontroller to provide drive for the rotation of the drill bit.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This rotary CNC vertical drilling machine has the following advantages:
[0015] The worm gear rotates by manually turning the dial, which in turn drives the rotating column to rotate. This causes the sliding column at the bottom of the clamping block to both rotate and slide within the sliding hole in the turntable at the top of the rotating column. This allows the four clamping blocks to move synchronously towards the center, achieving stable clamping of the workpiece to be drilled. When processing different workpieces, it is not necessary to constantly disassemble and change the clamps, resulting in better adaptability and ensuring the stability of the workpiece during drilling operations.

The bottom end of the output shaft of the second motor 12 is fixedly connected to the top end of the drill bit 4. The input end of the second motor 12 is electrically connected to the output end of the microcontroller 14. Through the control of the microcontroller 14, the first motor 11, the second motor 12 and the electric push rod 13 start to run synchronously. The output shaft of the first motor 11 will drive the drill bit 4, which is fixedly connected at the bottom end, to rotate at high speed. The telescopic end of the electric push rod 13 will push the support frame 6 to slide upward inside the slide groove 5, thereby causing the high-speed rotating drill bit 4 to drill holes in the workpiece. After drilling is completed, the telescopic rod of the electric push rod 13 retracts, causing the drill bit 4 to leave the inside of the workpiece. The output shaft of the first motor 11 will drive the gear 10 to start rotating. Through the meshing gear ring 9, the placement table 71 starts to rotate on the upper surface of the support frame 6 to adjust the position of the workpiece to be drilled. The above movements are repeated to drill holes.
[0022] Clamping mechanism 7 includes a placement platform 71, guide grooves 72, clamping blocks 73, rotating columns 74, turntables 75, sliding holes 76, and sliding columns 77. The placement platform 71 is rotatably connected to the upper surface of the support frame 6. Guide grooves 72 are respectively opened on the upper surface of the placement platform 71. Clamping blocks 73 are slidably connected inside the guide grooves 72. Sliding columns 77 are fixedly connected to the bottom ends of the clamping blocks 73. The rotating column 74 is rotatably connected to the bottom wall of the placement platform 71. The turntable 75 is fixedly connected to the top end of the rotating column 74.

A dial wheel 8 is fixedly connected to one end of the worm 79 extending to the outside of the platform 71. The dial wheel 8 is provided with evenly distributed anti-slip rods. When a rotary CNC vertical drilling machine is needed for part processing and manufacturing, the part to be drilled is first placed on the upper surface of the platform 71. The dial wheel 8 is rotated to make the worm 79 start to rotate. The meshing worm wheel 78 makes the rotating column 74 start to rotate, which drives the turntable 75 to start to rotate. The sliding column 77 rotates and slides inside the vertically corresponding sliding hole 76. Then, the four clamping blocks 73 slide inside the guide groove 72 under the drive of the sliding column 77. The four clamping blocks 73 move synchronously towards the center to fix the part to be processed.
[0023] The working principle of the rotary CNC vertical drilling machine provided by this utility model is as follows: When a rotary CNC vertical drilling machine is needed for parts processing and manufacturing, the part to be drilled is first placed on the upper surface of the placement table 71. The dial wheel 8 is rotated to make the worm gear 79 start to rotate. Through the meshing worm wheel 78, the rotating column 74 starts to rotate, which drives the turntable 75 to start rotating. The sliding columns 77 all rotate and slide inside the vertically corresponding sliding holes 76. Then, the four clamping blocks 73 slide inside the guide grooves 72 under the drive of the sliding columns 77. The four clamping blocks 73 move synchronously towards the center (the four guide grooves 72 are evenly distributed at equal angles with the central axis of the rotating column 74 as the center, and the center of the circle where the sliding hole 76 is located is not located on the central axis of the rotating column 74). (Above) The part to be processed is fixed. Under the control of the microcontroller 14, the first motor 11, the second motor 12 and the electric push rod 13 start to run synchronously. The output shaft of the first motor 11 drives the drill bit 4 fixed at the bottom to rotate at high speed. The telescopic end of the electric push rod 13 pushes the support frame 6 to slide upward inside the slide groove 5, thereby causing the high-speed rotating drill bit 4 to drill a hole in the part to be processed. After drilling is completed, the telescopic rod of the electric push rod 13 retracts, causing the drill bit 4 to leave the inside of the part. The output shaft of the first motor 11 drives the gear 10 to start rotating. Through the meshing gear ring 9, the placement table 71 starts to rotate on the upper surface of the support frame 6 to adjust the position of the part to be drilled. The above movement is repeated to drill holes.
