[0021] By adopting the above technical scheme, when the drilling and tapping machine processes the parts, the worker can directly place the parts to be processed on the first fixed plate 3, and then start the first motor 4. The first motor 4 drives the internal thread plate 5 to operate to clamp and limit the parts, and then start the baffle 2 and the drilling and tapping device 12. After the baffle 2 is started, it drives the parts to move. When the baffle 2 drives the parts to move to the lower side of the drilling and tapping device 12, the parts are processed by the drilling and tapping device 12. After the processing is completed, the baffle 2 continues to drive the parts to move. When the baffle 2 drives the parts to move above the guide plate 6, the first motor 4 operates to move the internal thread plate 5, so that the internal thread plate 5 returns to its position, so that the processed parts can be unloaded through the guide plate 6. By setting an automatic feeding mechanism, the drilling and tapping machine can automatically clamp and feed the parts when processing the parts, so that workers do not need to clamp them manually, which effectively improves the processing efficiency.

[0022] An auxiliary mechanism is arranged at the middle end of the baffle 2, and the auxiliary mechanism includes a shell 7, a turntable 8 and a spring 9. The shell 7 is arranged on the inner side of both ends of the baffle 2, and the turntable 8 is arranged at the end of the shell 7 away from the baffle 2, and the spring 9 is arranged at the outer end of the turntable 8.

[0023] By adopting the above technical solution, when the debris generated by drilling and tapping falls on the baffle 2, when part of the baffle 2 rotates to the lower end, the shell 7 is started, and the turntable 8 is driven to rotate by the shell 7. After the turntable 8 rotates, it drives the spring 9 to intermittently hit the lower end of the baffle 2, so that the debris attached to the baffle 2 falls off. By setting an auxiliary mechanism, the debris attached to the baffle 2 can be cleaned when the drilling and tapping machine processes the parts, which is convenient for subsequent cleaning.

[0024] The inner side of the middle end of the machine tool 1 is fixedly connected to a baffle plate 2 , and the outer side of one end of the baffle plate 2 is fixedly connected to a motor 21 . The output shaft of the motor 21 passes through the baffle plate 2 and is fixedly connected to a conveyor belt 22 , and the end of the conveyor belt 22 away from the motor 21 is transferred to the baffle plate 2 .

[0025] By adopting the above technical solution, by arranging the baffle 2, the motor 21 and the conveyor belt 22, it is convenient to drive the parts to be automatically fed.

[0026] The outer side of the middle end of the conveyor belt 22 is fixedly connected to the first fixing plate 3 , and the outer sides of both ends of the first fixing plate 3 are fixedly connected to the second fixing plates 31 .

[0027] By adopting the above technical solution and providing the first fixing plate 3 and the second fixing plate 31 , it is convenient to support the first motor 4 and the internal thread plate 5 .

[0028] The opposite sides of the two sets of second fixing plates 31 are fixedly connected to the first motor 4 , and the output shaft of the first motor 4 passes through the second fixing plates 31 and is fixedly connected to the external threaded rod 41 .

[0029] By adopting the above technical solution and providing the first motor 4 and the externally threaded rod 41 , it is convenient to drive the internally threaded plate 5 to rotate.

[0030] The outer side of one end of the external threaded rod 41 away from the first motor 4 is inserted into the internal threaded plate 5, and the side of the internal threaded plate 5 away from the external threaded rod 41 is fixedly connected to the rubber pad 51, and the two ends of the side of the internal threaded plate 5 close to the second fixed plate 31 are fixedly connected to the telescopic rod 52, and the end of the telescopic rod 52 away from the internal threaded plate 5 passes through and is fixedly connected in the second fixed plate 31.

[0031] By adopting the above technical solution, by providing the internal thread plate 5, the rubber pad 51 and the telescopic rod 52, it is convenient to clamp and fix the parts.

[0032] The inner side of one end of the baffle 2 close to the guide plate 6 is fixedly connected to the outer shell 7, and a second motor 71 is inserted and fixedly connected inside the outer shell 7. The output shaft of the second motor 71 is fixedly connected to a transmission rod 72, and the end of the transmission rod 72 away from the second motor 71 passes through the outer shell 7 and is fixedly connected to the turntable 8. The outer side of the turntable 8 is fixedly connected to a connecting plate 81.

[0033] By adopting the above technical solution, by arranging the housing 7, the second motor 71, the transmission rod 72, the rotating disk 8 and the connecting plate 81, it is convenient to drive the spring 9 to operate.

[0034] A fixed spring 9 is inserted inside the end of the connecting plate 81 away from the rotating disk 8 , and the end of the spring 9 away from the rotating disk 8 is fixedly connected to a striking block 91 , and the end of the striking block 91 close to the spring 9 is inserted in the connecting plate 81 .

[0035] By adopting the above technical solution and providing the spring 9 and the striking block 91 , it is convenient to perform intermittent striking on the lower end of the baffle 2 .

[0036] Working principle: when drilling and tapping parts, first start the motor 21 and the second motor 71. After the motor 21 is started, the output shaft drives the conveyor belt 22 to rotate. After the conveyor belt 22 rotates, it drives the first fixed plate 3 to rotate. After the second motor 71 is started, the output shaft drives the transmission rod 72 and the turntable 8 to rotate. After the turntable 8 rotates, it drives the connecting plate 81, the spring 9 and the striking block 91 to rotate. The rotation of the striking block 91 is used to intermittently strike the lower end of the baffle 2. When the striking block 91 hits the baffle 2, the recoil force inserts the compressed spring 9 into the connecting plate 81. The debris attached to the lower end of the conveyor belt 22 is knocked off by intermittent striking. Then the parts are placed on the middle end of the upper side of the first fixed plate 3, and then the first motor 4 is started. The output shaft of the first motor 4 rotates clockwise to drive the external threaded rod 41 to rotate. After the external threaded rod 41 rotates, it engages with the thread of the internal threaded plate 5, allowing the internal threaded plate 5 to drive the rubber pad 51 to extend. The parts are supported and fixed under the limit of the retractable rod 52, and then the conveyor belt 22 continues to drive the clamped parts to move. When the conveyor belt 22 drives the clamped parts to move to the lower side of the drilling and tapping device 12, the motor 21 is turned off at this time, and the drilling and tapping device 12 is started and the clamped parts are processed. After the processing is completed, the drilling and tapping device 12 is turned off and the motor 21 is continued to be started. After the motor 21 is started, it drives the processed parts to move, and at the same time drives the next group of parts to be processed to move to the lower side of the drilling and tapping device 12 for processing. When the processed parts move to the upper end of the guide plate 6, the first motor 4 is started at this time, and the output shaft of the first motor 4 rotates counterclockwise to drive the external threaded rod 41 to rotate, so that the internal threaded plate 5 drives the rubber pad 51 away from the processed parts under the limit of the telescopic rod 52. As the conveyor belt 22 rotates, the processed parts are guided by the guide plate 6 and fall to the designated area for collection.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
