At this time, the end face of the turntable 4 is perpendicular to the top plane of the fixture base 1, and the tool of the machine tool body 31 is started to process the side of the part blank.

[0030] As a technical optimization scheme of the present invention, the debris cleaning mechanism includes a collection trough 25, a belt 27, and a cleaning brush 29. The top of the fixture base 1 is provided with a collection trough 25 between the two fixture supports 2.

[0033] As a technical optimization solution of the present invention, a third locking block 33 is fixedly connected to the top of the third electric telescopic rod 24, the third locking block 33 is adapted to the slot 23, and the third locking block 33 and the slot 23 are both configured to be conical.

[0034] As a technical optimization solution of the present invention, a through groove 34 is formed at one end of the collecting groove 25 away from the roller 26 , and the through groove 34 is connected to the inclined groove 32 .

[0035] Working principle: This CNC machine tool processing center is mainly composed of a machine tool body 31, a circular rotation mechanism, a 90-degree flip mechanism, and a debris cleaning mechanism, and is mainly used for drilling, expanding, reaming, and other processing of parts. In the initial state, the second locking block 16 is plugged into the inside of the turntable 3, and the plugging position is located in the middle of the side of the turntable 3 close to the second locking block 16, and the end face of the turntable 4 is parallel to the top plane of the fixture base 1. When working, the part blank is first placed on the top of the turntable 4, and then the cylinder 6 is started. The output end of the cylinder 6 tightly abuts the part blank on the V-shaped surface of the V-shaped block 5. The cylinder 6, the V-shaped block 5 and the turntable 4 are combined to complete the locking and positioning of the part blank. Then the machine tool body 31 is started, and the tool of the machine tool body 31 processes the part blank. When there are multiple holes to be processed at the top of the part, or there are holes to be processed on the side of the part, the circular rotation mechanism and the 90-degree flip mechanism are started.

[0036] Working process of the circular rotating mechanism: when the first hole at the top of the part blank is processed, the stepper motor 7 is started, the output end of the stepper motor 7 drives the first gear 8 to rotate, the first gear 8 drives the second gear 9 meshing with it to rotate, the second gear 9 drives the turntable 4 to rotate through the short shaft, the turntable 4 drives the part blank to rotate one station around the axis of the short shaft, then the stepper motor 7 stops working, the air pump 17 is started immediately, the air pump 17 pushes the gas into the air guide tube 18, the air pressure inside the air guide tube 18 and the air cylinder 19 increases The air pressure pushes the piston 20, and the piston 20 pushes the rubber block 22 through the push rod 21, so that the rubber blocks 22 at both ends of the turntable 4 are tightly squeezed on the outer wall of the turntable 4, fixing the turntable 4 to prevent it from deviating from the workstation due to the inertia generated by the rotation, and then starting the third electric telescopic rod 24, the output end of which pushes the third locking block 33 into the slot 23, and the third locking block 33 cooperates with the conical inclined surface of the slot 23 to correct the position of the turntable 4, and lock the turntable 4 in the processing station to prevent it from shaking. At this time, the tool of the machine tool body 31 can be started to process the second hole of the part blank. Similarly, until the holes at the top of the blank are all processed.

[0037] The working process of the 90-degree flipping mechanism: when the top of the part blank is processed, it is necessary to drill holes on its side, etc., then start the flipping motor 10 and the second electric telescopic rod 15, and the output end of the second electric telescopic rod 15 pulls the second locking block 16 out of the inside of the turntable 3, so that the turntable 3 is flipped 90 degrees around the axis of the rotating shaft. After the flipping motor 10 is started, its output end drives the third gear 11 to rotate, and the third gear 11 drives the fourth gear 12 meshing with it to rotate, and the fourth gear 12 drives the turntable 3 to rotate through the rotating shaft. After the turntable 3 rotates 90 degrees, its lower part abuts against the baffle at the lower part of the fixture support 2, and the flipping motor 10 stops running, and the first electric telescopic rod 13 is started, and its output end extends and pushes the first locking block 14, so that the first locking block 14 is inserted into the inside of the turntable 3, locking the position of the turntable 3 to prevent it from shaking. At this time, the end face of the turntable 4 is perpendicular to the top plane of the fixture base 1. The tool of the machine tool body 31 is started to process the side of the part blank. If there are multiple holes on the side of the part blank that need to be processed, the stepper motor 7 is started, and the circular rotation mechanism works. The circular rotation mechanism drives the part blank to rotate, so that the tool can process different parts of the side of the blank. After all the holes on the side of the blank are processed, the flip motor 10 and the first electric telescopic rod 13 are started, the output end of the first electric telescopic rod 13 is shortened, and the turntable 3 rotates 90 degrees in the opposite direction to return to the initial state. When the end of the turntable 3 abuts against the baffle on the upper part of the fixture support 2, the flip motor 10 stops working, and the second electric telescopic rod 15 is started. Its output end drives the second locking block 16 to be inserted into the inside of the turntable 3 to prevent it from shaking, so as to facilitate the processing of the next part blank.

[0038] Working process of the debris cleaning mechanism: When the part blank is processed by drilling, reaming, reaming, etc., a large amount of debris will be generated, and these debris will fall on the turntable 4 and the turntable 3. After the turntable 3 is turned down by 90 degrees from the horizontal position, the debris on the surface of the turntable 3 and the turntable 4 will fall into the inside of the collection tank 25. When the tool processes the side of the part blank, due to gravity and the vibration of the machine tool, the debris will directly fall into the collection tank 25. When the turntable 3 is flipped downward by 90 degrees from the horizontal position to the vertical position, the belt 27 is pulled, the upper belt 27 gradually extends, and the lower belt 27 gradually shortens, and the belt 27 drives the cleaning brush 29 to move in the direction close to the roller 26, and the cleaning brush 29 moves from the starting position (the end of the collecting groove 25 away from the roller 26) to the final position (the end of the collecting groove 25 close to the roller 26), and pushes the debris in the collecting groove 25 into the inclined groove 32 during the movement. After the turntable 3 is rotated to the vertical position, the debris on the turntable 3 may fall into the collecting groove 25 behind the cleaning brush 29. A through groove 34 is opened downward on the rear side of the collecting groove 25, and the through groove 34 is connected to the inclined groove 32. When the turntable 3 is flipped back to the horizontal position from the vertical position, the cleaning brush 30 returns to the starting position due to the elastic force of the reset spring 30. During the movement, the debris on the rear side of the cleaning brush 30 is pushed into the inclined groove 32 through the through groove 34.
