DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings: Example 1

[0026] See also Figure 1-Figure 7 In an embodiment of the present invention, a CNC milling, drilling and tapping integrated machine tool with high production efficiency includes a frame 1 and a multi-axis drilling tool 2. The multi-axis drilling tool 2 is installed on the top of the frame 1. A mounting slot 3 is opened in the middle of the frame 1. A fixed seat 4 is fixedly connected to the inner bottom wall of the mounting slot 3. A movable platform 6 is provided above the fixed seat 4 through a left and right moving component 5. A mounting plate 7 is fixedly connected to the upper surface of the movable platform 6. A first clamp 8 is provided on the rear side of the upper surface of the mounting plate 7. A second clamp 9 is provided on the front side of the upper surface of the mounting plate 7. A feeding component 10 is provided on the front side of the upper surface of the fixed seat 4. A storage component 11 is provided on the left side of the fixed seat 4.

[0027] Specifically, the multi-axis drilling tool 2 is equipped with a drill bit 201, a milling cutter 202 and a tap 203, so that the drill bit 201 is provided on the multi-axis drilling tool 2 to drill a hole, and after the drilling is completed, the motor 501 is started to drive the movable platform 6 to move to the left, and then sequentially complete the milling, drilling and tapping work;

[0028] Among them, the left and right moving component 5 includes a motor 501 and a screw rod 502, and the left and right sides of the movable platform 6 are fixedly connected with the left side plate 503 and the right side plate 504 respectively. The motor 501 is installed on the right side of the right side plate 504, one end of the screw rod 502 is fixedly connected to the output end of the motor 501, and the other end of the screw rod 502 passes through the fixed seat 4 and is rotatably connected to the left side plate 503 through a bearing. The screw rod 502 is threadedly connected to the fixed seat 4. The setting is such that the starting motor 501 drives the screw rod 502 to rotate. Since the screw rod 502 is threadedly connected to the fixed seat 4, and the motor 501 is fixedly connected to the right side plate 504 on the right side of the movable platform 6, the screw rod 502 can drive the movable platform 6 to move during the rotation process;

[0029] Among them, the right side of the left plate 503 is fixedly connected to two guide rods 505, the right end of the guide rod 505 passes through the fixed seat 4 and is fixedly connected to the right side plate 504, the guide rod 505 is slidably connected to the fixed seat 4, so that the guide rod 505 is provided to guide the movable platform 6, so that the movable platform 6 moves more stably;

[0030] Furthermore, the first fixture 8 includes a fixed plate 801, a first electric push rod 802 and a first clamping block 803. The fixed plate 801 is fixedly connected to the upper surface of the mounting plate 7. The first electric push rod 802 is mounted on the back of the fixed plate 801. The first clamping block 803 is fixedly connected to the output end of the first electric push rod 802. The front of the first clamping block 803 is provided with a first positioning groove 804. In this way, when the movable platform 6 moves to the left to the storage assembly 11, the second electric push rod 902 is activated to retract and drive the second clamping block 903 to reset. At the same time, the first electric push rod 802 is activated to extend and drive the first clamping block 803 to move forward. During the movement, the first clamping block 803 pushes the parts into the storage assembly 11.

[0031] Furthermore, the second clamp 9 includes an L-shaped plate 901, a second electric push rod 902 and a second clamping block 903. The L-shaped plate 901 is fixedly connected to the upper surface of the mounting plate 7, the second electric push rod 902 is installed on the front of the L-shaped plate 901, and the second clamping block 903 is fixedly connected to the output end of the second electric push rod 902. A second positioning groove 904 is provided on the back of the second clamping block 903. When the second clamping block 903 is moved to the through groove 1003 and aligned with the part, the second electric push rod 902 is started to extend to drive the second clamping block 903 to push the part to move. Since the inner bottom wall of the through groove 1003 is flush with the upper surface of the mounting plate 7, the second electric push rod 902 will push the part onto the mounting plate 7 and fix it through the first clamping block 803. Example 2

[0032] See also Figure 3-Figure 7 , which is different from Example 1:

[0033] Specifically, the feeding assembly 10 includes a fixed column 1001 and a hopper 1002, the fixed column 1001 is fixedly connected to the upper surface of the fixed seat 4, and the hopper 1002 is fixedly connected to the top of the fixed column 1001, and a through slot 1003 is provided on the left side of the fixed column 1001, and the upper surface of the mounting plate 7 is flush with the inner bottom wall of the through slot 1003, the size of the through slot 1003 is larger than the size of the second clamping block 903, and a through hole 1004 is provided on the upper surface of the through slot 1003, which passes through the upper surface of the fixed column 1001 and is connected to the hopper 1002, and a fixing assembly 1005 corresponding to the L-shaped plate 901 is provided on the left side of the fixed column 1001. In this way, the parts to be processed are placed one by one in the hopper 1002, and the parts will slide into the through hole 1004, and the bottom part will fall on the inner bottom wall of the through slot 1003;

[0034] Among them, the fixing assembly 1005 includes a fixed box 1006, a movable rod 1007, a first limit block 1008, a second limit block 1009, a first spring 1010, a second spring 1011, a connecting rod 1012 and a clamping plate 1013. The fixed box 1006 is fixedly connected to the left side of the fixed column 1001. The first limit block 1008 and the second limit block 1009 are both slidably connected to the inside of the fixed box 1006. One end of the first spring 1010 is fixedly connected to the first limit block 1008, and the other end of the first spring 1010 is fixedly connected to the second limit block 1009. The left end of the movable rod 1007 passes through the fixed box 1006, and the movable rod 1007 is slidably connected to the fixed box 1006. The right end of the movable rod 1007 is located inside the fixed box 1006 and is fixedly connected to the first limit block 1008. The left end of the connecting rod 1012 is fixedly connected to the second limit block 100 9 is fixedly connected, the right end of the connecting rod 1012 is located inside the through hole 1004 and is fixedly connected to the clamping plate 1013, the second spring 1011 is sleeved on the outer surface of the connecting rod 1012, one end of the second spring 1011 is fixedly connected to the second limit block 1009, and the other end of the second spring 1011 is fixedly connected to the right inner wall of the fixed box 1006. In this way, when the L-shaped plate 901 on the mounting plate 7 squeezes the movable rod 1007, since the compression force of the first spring 1010 is greater than that of the second spring 1011, the second limit block 1009 drives the connecting rod 1012 to move right and compresses the second spring 1011. During the movement, the connecting rod 1012 drives the clamping plate 1013 to press the parts in the through hole 1004. Since the second electric push rod 902 is in a contracted state, the movable platform 6 continues to move to the right. At this time, the first spring 1010 will be compressed;

[0035] Among them, the storage component 11 includes a storage box 1101, a buffer plate 1102 and a third spring 1103. The storage box 1101 is fixedly connected to the left side of the fixed seat 4. The back of the buffer plate 1102 is connected to the back inner wall of the storage box 1101 through a rotating shaft. The front of the buffer plate 1102 is inclined. The top of the third spring 1103 is fixedly connected to the buffer plate 1102, and the bottom end of the third spring 1103 is fixedly connected to the inner wall of the storage box 1101. In this way, when the parts fall onto the buffer plate 1102 in the storage box 1101, the buffer plate 1102 is impacted and can rotate around the rotating shaft and compress the third spring 1103. The third spring 1103 is used for buffering, thereby reducing the impact of the parts and avoiding collisions between the parts.

[0036] The working principle of the present invention is: when in use, the parts to be processed are placed one by one in the hopper 1002, and the parts will slide into the through hole 1004, and the parts at the bottom will fall on the inner bottom wall of the through groove 1003, and then the motor 501 is started to drive the screw rod 502 to rotate forward. Since the screw rod 502 is threadedly connected to the fixed seat 4, and the motor 501 is fixedly connected to the right side plate 504 on the right side of the movable platform 6, the screw rod 502 can drive the movable platform 6 to move to the right during the rotation. When the L-shaped plate 901 on the mounting plate 7 squeezes the movable rod 1007, since the compression force of the first spring 1010 is greater than that of the second spring 1011, the second limit block 1009 drives the connecting rod 502 to rotate forward. The connecting rod 1012 moves to the right and compresses the second spring 1011. During the movement, the connecting rod 1012 drives the clamping plate 1013 to press the part in the through hole 1004. Since the second electric push rod 902 is in a contracted state, the movable platform 6 continues to move to the right. At this time, the first spring 1010 will be compressed until the second clamping block 903 moves to the through groove 1003 and aligns with the part. Then the second electric push rod 902 is started to extend and drives the second clamping block 903 to push the part to move. Since the inner bottom wall of the through groove 1003 is flush with the upper surface of the mounting plate 7, the second electric push rod 902 will push the part onto the mounting plate 7 and fix it through the first clamping block 803. Then, the drill bit 201 on the multi-axis drilling tool 2 is used to drill a hole. After the drilling is completed, the motor 501 is started to drive the screw rod 502 to reverse. Since the screw rod 502 is threadedly connected to the fixed seat 4, and the motor 501 is fixedly connected to the right side plate 504 on the right side of the movable platform 6, the screw rod 502 can drive the movable platform 6 to move to the left during the rotation, and then complete the milling, drilling and tapping work in sequence. When the movable platform 6 moves to the left, the first spring 1010 is reset first, and the second spring 1011 always maintains the pressure of the clamping plate 1013 to prevent the parts from slipping. When the second clamp 9 on the movable platform 6 is removed from the through slot 1003, the first spring 1010 is reset. At this time, the second spring The spring 1011 will reset, and the bottom part will fall on the inner bottom wall of the through groove 1003, which is convenient for loading the next part. When the movable platform 6 moves to the left to the storage component 11, the second electric push rod 902 is started to contract and drive the second clamping block 903 to reset. At the same time, the first electric push rod 802 is started to extend and drive the first clamping block 803 to move forward. During the movement, the first clamping block 803 pushes the part to fall onto the buffer plate 1102 in the storage box 1101. At this time, the buffer plate 1102 is impacted and can rotate around the rotating axis and compress the third spring 1103. The third spring 1103 is used for buffering, which reduces the impact of the parts and avoids collisions between the parts.
