Description

Technical Field

[0001] This utility model relates to the field of drilling and tapping center machines, and in particular to a high-speed drilling and tapping center machine. Background Technology

[0002] In the field of machining, drilling and tapping centers are commonly used equipment for cutting metal. They are also known as drilling and milling tapping centers, drilling and tapping centers, drilling and milling centers, and drilling and milling machining centers. They are mainly used for drilling and tapping operations on small metal workpieces. Drilling and tapping centers are currently the most efficient and precise machine tools on the market that integrate cutting, drilling, and tapping. They are derived from traditional metal cutting machine tools, namely vertical machining centers.

[0003] Traditional drilling and tapping centers have certain limitations in design and function, making it difficult to meet the high-efficiency requirements of modern manufacturing. Existing drilling and tapping centers generally use robotic arms to assist in material changing, but the robotic arms can only perform single pick-up and drop-off. The processed material must be taken out first before the material to be processed can be put in. In addition, the robotic arm usually requires complex structure and operation to achieve clamping and centering of the material. All of these factors result in long waiting times, compress the working time of the drilling and tapping center, and indirectly lead to an increase in production costs.

[0004] Therefore, it is necessary to provide a new high-speed drilling and tapping center machine to solve the above-mentioned technical problems. Utility Model Content

[0028] Please see Figure 1 and Figure 5The rotating structure 5 includes: a rotating column 6, a first worm gear 7, a first motor 8, and a first worm 9. The rotating column 6 is fixedly connected to the bottom of the turntable 2, and the first worm gear 7 is fixedly connected to the bottom of the rotating column 6.

[0030] The working principle of the high-speed drilling and tapping center machine provided by this utility model is as follows:

[0031] Rotation process: The second motor 20 is started, which drives the bidirectional worm gear 21 to rotate. The rotation of the bidirectional worm gear 21 drives the two second worm wheels 19 to rotate, one of which rotates clockwise and the other counterclockwise. After the chip gate 3 has rotated 90 degrees, the first motor 8 is started. The first motor 8 drives the first worm gear 9 to rotate, which drives the first worm wheel 7 to rotate counterclockwise. The first worm wheel 7 drives the rotating column 6 to rotate counterclockwise, which drives the turntable 2 to rotate counterclockwise. The turntable 2 drives the material tray to rotate counterclockwise. As the turntable 2 rotates, the pressure block 13 on the side of the material tray will contact the arc-shaped wall 4 on one side of the drilling platform and the arc-shaped track at the bottom of the drilling platform. The arc-shaped wall 4 and the arc-shaped track squeeze the pressure block 13, which squeezes the telescopic column 12. The telescopic column 12 squeezes the spring 24. The pressure block 13, through the connecting rod 14 fixedly connected to it, drives the two clamping blocks 11 fixedly connected to the connecting rod 14 to move closer to each other. When the two clamping blocks 11 approach each other, they will drive the L-shaped connecting rods 17 connected to them to move in the same direction. The L-shaped connecting rods 17 drive the rotating ring 16 to rotate counterclockwise. The rotation of the rotating ring 16 drives the other two L-shaped connecting rods 17 connected to it to move. The other two L-shaped connecting rods 17 will drive the clamping blocks 11 connected to them to move closer to each other. All four clamping blocks 11 will drive the telescopic stop rods 15 fixedly connected to them to move in the same direction, thus completing the clamping of the material. When the rotating column 6 rotates 90 degrees, the first motor 8 is turned off and the second motor 20 is started. The second motor 20 drives the bidirectional screw to rotate in the opposite direction. The bidirectional screw drives the two second worm gears 19 to rotate. One worm gear rotates counterclockwise and the other worm gear rotates clockwise. After the chip gates 3 are all reset, the second motor 20 is turned off. In addition, the spring 24 in the telescopic column 12 inside the material tray of the rotating drilling platform pushes the telescopic column 12 to extend. The telescopic column 12 drives the pressure blocks 13 to move away from each other. The subsequent steps are the reverse of those of the rotating drilling platform.
