[0003] In the process of metal blade processing, drilling is a common and critical process. Traditional metal blade drilling processing is usually carried out by ordinary drilling machines. This method has many disadvantages. On the one hand, the automation level of ordinary drilling machines is low, and manual clamping, positioning and adjustment are required frequently. Not only is the labor intensity high, but the processing efficiency is low, which is difficult to meet the needs of large-scale production.

[0004] On the other hand, the processing precision of ordinary drilling machines is limited, and it is difficult to ensure the accuracy and consistency of the drilling position, which easily leads to unstable processing quality of the blade and affects the performance and life of the blade;

[0005] In terms of blade clamping, traditional metal blade drilling equipment does not have a corresponding clamping and fixing structure, which may cause the blade to move during the drilling process, reducing the drilling quality of the blade. At the same time, if the metal chips generated during the drilling process cannot be collected and cleaned up in a timely and effective manner, it will not only affect the cleanliness of the working environment, but may also interfere with the normal operation of the equipment, and even damage the equipment, reducing the service life of the equipment.

[0021] The present invention provides a CNC drilling machine for metal blade processing, which has the following beneficial effects:

[0022] 1. The CNC drilling machine for processing metal blades places the metal blade in the placement groove of the blade cylinder through the setting of the blade placement mechanism. The clamp clamps the blade under the action of the elastic steel sheet. The second motor drives the second transmission shaft to rotate, and then the blade cylinder rotates, so that the blade to be processed is placed directly below the drilling mechanism. The placement grooves are evenly distributed along the axis of the blade cylinder, which can realize the placement of multiple blades. Multiple blades can be processed in one clamping, which improves the processing efficiency. The elastic clamping method of the clamping part can firmly fix blades of different specifications, and it is easy to install and disassemble, which meets the processing requirements of metal blades of different sizes. The positioning sleeve in the positioning part coincides with the axis of the drill bit, which ensures the accuracy of the drilling position and improves the processing accuracy.

[0023] 2. The CNC drilling machine for processing metal blades has a mounting mechanism, in which a rotating ring on the outer surface of the blade cylinder is mounted in a rotating groove of a first fixed ring, so that the blade mounting mechanism can be rotatably mounted in the mounting mechanism. The mounting mechanism provides a stable support and rotation basis for the blade mounting mechanism. The structural design of the two fixed seats and the first fixed ring ensures the stability of the blade mounting mechanism during rotation, reduces shaking, makes drilling processing more stable, and improves processing quality. The cooperation between the rotating groove and the rotating ring enables the blade mounting mechanism to rotate flexibly, which is convenient for adjusting the blade position for processing.

[0024] 3. The CNC drilling machine for processing metal blades has a chip feeder and a chip collector. During the drilling process, the metal chips generated enter the tool barrel through the chip feed tube and then fall into the chip collection tube. The protective pad at the end of the chip feed tube prevents the blade from being damaged by direct contact with the chip feed tube. The chip feed ring guides the metal chips into the chip collection tube smoothly. After the processing is completed, the chip collection tube is unscrewed by the handle for cleaning. The chip feeder and the chip collection tube can effectively collect and clean the metal chips, keep the working environment clean, reduce the wear of the equipment and the influence of the processing accuracy on the metal chips, and the protective pad protects the blade from damage during the processing, thereby improving the yield rate of the blade.

[0025] Fourth, the CNC drilling machine for processing metal blades has a lifting mechanism. The telescopic end of the cylinder drives the telescopic rod to move up and down, so that the slider fixed on the top of the telescopic rod slides in the through hole, and the height of the drilling mechanism is adjusted to keep the drill bit at a suitable distance from the blade surface. The lifting mechanism can flexibly adjust the height of the drilling mechanism, thereby improving the versatility of the equipment.

[0026] 5. The CNC drilling machine for processing metal blades starts the first motor through the setting of the drilling mechanism. The first motor drives the drill bit to rotate at high speed through the first transmission shaft. At the same time, the cylinder pushes the telescopic rod to move downward, so that the drill bit gradually approaches and drills into the metal blade for drilling. The first motor drives the drill bit through the first transmission shaft, which can provide stable drilling power and ensure the efficiency and quality of drilling.

[0058] The second motor 9 is started. The second motor 9 is controlled by the controller to make the second transmission shaft 10 rotate intermittently and drive the knife placement mechanism 3 to rotate. The positioning sleeve 342 on the third fixing ring 341 will rotate to a position opposite to the drill bit 85, and the drill bit 85 can coincide with the axis of the positioning sleeve 342 to achieve accurate positioning;

[0059] The first motor 83 is started, and the first motor 83 drives the drill bit 85 to rotate at high speed through the first transmission shaft 84. At the same time, the cylinder 71 is started, and the cylinder 71 pushes the telescopic rod 72 to move downward, so that the slider 73 fixed on the top of the telescopic rod 72 slides in the through hole 5, and the height of the drilling mechanism 8 is adjusted. The drill bit 85 gradually approaches and drills into the metal blade to perform the drilling operation. During the drilling process, the generated metal chips will enter the inside of the knife barrel 31 through the chip feed tube 361. The protective pad 362 at the end of the chip feed tube 361 can prevent the blade from being directly contacted with the chip feed tube 361 and damaged;

[0060] After the drilling of one blade is completed, the cylinder 71 drives the drilling mechanism 8 to rise and reset;

[0061] The second motor 9 continues to rotate the blade placement mechanism 3, and rotates the placement slot 35 with the next blade to the drilling position, and repeats the above positioning, adjustment and drilling steps to process the next blade;

[0062] When all the blades are processed, turn off the first motor 83 and the second motor 9, hold the handle 382 on the chip collecting barrel 381, rotate the chip collecting barrel 381 out of the knife barrel 31, and clean the metal chips collected in the chip collecting barrel 381 for next use.
