Description

Technical Field

[0001] The invention relates to the technical field related to mechanical processing, and in particular to a material blocking structure based on CNC lathe processing. Background Art

[0002] With the rapid development of modern industry, the requirements for the precision, quality and production efficiency of mechanical parts are getting higher and higher. Traditional ordinary lathe processing can no longer meet the needs of complex-shaped parts, high-precision parts and large-scale production. Against this background, CNC lathes came into being. They can realize automated and high-precision processing and provide strong technical support for the upgrading of the manufacturing industry. During the processing, if there is no blocking structure, the workpiece may exceed the processing range and collide with other parts or tools of the machine tool, resulting in damage to the machine tool and breakage of the tool. The blocking structure can limit the moving range of the workpiece and avoid collision accidents. Therefore, there is a special need for a blocking structure based on CNC lathe processing.

[0003] However, the existing stopper structure based on CNC lathe processing usually has poor accuracy when detecting the stroke of the stopper action on the workpiece position. In a more complex processing environment, the detection signal may be interfered by the outside world, which may cause inaccurate stopper results and ultimately have an adverse effect on the processing accuracy. Summary of the invention

The motor shaft is fixed to one side of the conveyor belt by a fixed motor box, the motor drives the crawler belt to rotate, and the crawler belt drives the rotating shaft to rotate. Since the rotating shaft and the second connecting rod are rotatably connected, the rotating shaft drives the second connecting rod to rotate, the second connecting rod is rotatably connected to the transmission rod, and the second connecting rod drives the transmission rod to telescopically move on the inner wall surface of the fixed block. The fixed block is fixedly connected to one side of the conveyor belt, so the transmission rod will not shake when telescoping on the inner wall of the fixed block, and it is more stable. The transmission rod is rotatably connected to the first connecting rod, and the transmission rod drives the first connecting rod to move regularly. The first connecting rod is rotatably connected to the material blocking rod, and the rotation of the first connecting rod drives the material blocking rod to do telescopic movement. The sliding shaft below the material blocking rod is fixedly connected, and the sliding shaft is located on the inner wall of the limit block and is slidably connected to limit the movement range of the sliding shaft. Therefore, the material blocking rod performs telescopic movement in a certain range. In this way, the infrared sensor can quickly and accurately detect the workpiece or processing position, and trigger the crank-connecting rod mechanism to automatically perform the corresponding action without manual intervention, reducing the operation time and waiting time, thereby significantly improving the production efficiency.

After receiving the information, the infrared controller 916 transmits the signal to the motor 915 through the first circuit 917, thereby activating the motor shaft 915 to start working, and the motor shaft 915 is fixed to the motor shaft 915. The box 913 is fixed on one side of the conveyor belt 8, and the motor 915 drives the crawler belt 914 to rotate, and the crawler belt 914 drives the rotating shaft 911 to rotate. Since the rotating shaft 911 is rotatably connected with the second connecting rod 908, the rotating shaft 911 drives the second connecting rod 908 to rotate, and the second connecting rod 908 is rotatably connected with the transmission rod 902, and the second connecting rod 908 drives the transmission rod 902 to perform telescopic movement on the inner wall surface of the fixed block 901, and the transmission rod 902 is rotatably connected with the first connecting rod 903, and the transmission rod 902 drives the first connecting rod 903 to perform reciprocating linear motion, and the first connecting rod 903 is rotatably connected with the blocking rod 904, and the first connecting rod 903 rotates to drive the blocking rod 904 to perform telescopic movement, and the sliding shaft 905 below the blocking rod 904 is fixedly connected.The sliding shaft 905 is slidably connected to the inner wall of the limit block 906, which limits the range of movement of the sliding shaft 905, so the blocking rod 904 can move telescopically in a certain range. In this way, the infrared sensor can quickly and accurately detect the workpiece or processing position, triggering the crank connecting rod mechanism to automatically perform corresponding actions without manual intervention, reducing the operation time and waiting time, thereby significantly improving production efficiency.

[0028] Furthermore, the three-jaw chuck 5 is symmetrically arranged with respect to the central axis of the rotating disk 4, and the height limiting shaft 6 is symmetrically arranged with respect to the central axis of the rotating disk 4. Through the arrangement of the rotating disk 4, the three-jaw chuck 5 and the height limiting shaft 6, when in use, the three-jaw chuck 5 is symmetrically arranged with respect to the central axis of the rotating disk 4, so that the clamped workpiece is subjected to more uniform force during the rotation process, which helps to improve the machining accuracy and make the machined parts more accurate in size and higher in surface quality. The height limiting shaft 6 is symmetrically arranged with respect to the central axis of the rotating disk 4, which can effectively limit the axial position of the workpiece and ensure the consistency of the machining depth, which is crucial for machining tasks that require precise control of the axial size and improves the axial machining accuracy.

[0029] Furthermore, the transmission rod 902 forms a telescopic structure with the material-blocking rod 904 through the first connecting rod 903, and the outer wall size of the transmission rod 902 is consistent with the inner wall size of the fixed block 901. Through the arrangement of the fixed block 901, the transmission rod 902, the first connecting rod 903 and the material-blocking rod 904, when in use, the transmission rod 902 forms a telescopic structure with the material-blocking rod 904 through the first connecting rod 903, and the extension and retraction of the material-blocking rod 904 can be precisely controlled as needed. This can achieve accurate blocking and release of materials during material transmission and processing, and improve the accuracy and controllability of production. The outer wall size of the transmission rod 902 is consistent with the inner wall size of the fixed block 901, which ensures the stability and linearity of the transmission rod 902 during movement, thereby improving the accuracy of the telescopic structure.

[0030] Furthermore, the inner wall size of the second connecting rod 908 is consistent with the outer wall size of the connecting shaft 909, and the inner wall size of the rotating shaft 911 is consistent with the inner wall size of the connecting shaft 909. Through the arrangement of the second connecting rod 908, the connecting shaft 909 and the rotating shaft 911, when in use, the inner wall size of the second connecting rod 908 is consistent with the outer wall size of the connecting shaft 909, and the inner wall size of the rotating shaft 911 is consistent with the inner wall size of the connecting shaft 909. This tight fit enables the various components to maintain a good relative position during movement, reducing looseness and shaking. The precise size fit ensures the accuracy and stability of the transmission, avoids motion errors and energy losses caused by excessive clearance, and improves the reliability of the entire mechanism.

[0031] Furthermore, the rotating shaft 911 forms a rotating structure with the motor 915 through the track 914, and the sliding shaft 905 is slidably connected with the limit block 906 through the conveyor belt 8. Through the arrangement of the sliding shaft 905, the limit block 906, the conveyor belt 8, the transmission shaft 911, the track 914 and the motor 915, when in use, the rotating shaft 911 forms a rotating structure with the motor shaft 915 through the track 914. This connection method can ensure that the rotational power of the motor 915 is accurately transmitted to the rotating shaft 911, and can accurately control the rotation. The sliding 905 is movably connected with the limit block 906 through the conveyor belt 8, so that the sliding shaft 905 can perform precise linear motion in the limit block 906 driven by the conveyor belt 8, thereby further improving the processing accuracy of the entire system.

[0032] Furthermore, the outer wall size of the rotating shaft 911 is consistent with the inner wall size of the protective shaft 912, and the outer wall size of the protective shaft 912 is consistent with the inner wall size of the fixed motor box 913. Through the arrangement of the rotating shaft 911, the protective shaft 921 and the fixed motor box 913, when in use, the outer wall size of the rotating shaft 911 is consistent with the inner wall size of the protective shaft 921. This tight fit enables the rotating shaft to maintain a stable position during rotation, reducing shaking and deviation. The protective shaft 921 is consistent with the inner wall size of the fixed motor box 913, further enhancing the stability of the entire structure.

[0033] Furthermore, the outer wall size of the transmission rod 902 is consistent with the inner wall size of the first connecting rod 903, and the inner wall size of the first connecting rod 903 is consistent with the outer wall size of the material stopping rod 904. Through the arrangement of the transmission rod 902, the first connecting rod 903 and the material stopping rod 904, when in use, the outer wall size of the transmission rod 902 is consistent with the inner wall size of the first connecting rod 903, ensuring the efficient transmission of power from the transmission rod 902 to the first connecting rod 903, reducing energy loss and transmission error, and the inner wall size of the first connecting rod 903 is consistent with the outer wall size of the material stopping rod 904, so that the first connecting rod 903 can accurately transmit the motion to the material stopping rod 904, thereby realizing precise control of the function of the material stopping rod 904, and this close size matching enables the three components to maintain a relatively stable positional relationship during operation, reducing vibration and shaking caused by looseness or gaps.

[0034] Furthermore, the fixed rollers 12 are evenly spaced on the outer wall of the lathe 1, and the storage frame 11 is symmetrically arranged with respect to the central axis of the conveyor belt 8. Through the arrangement of the lathe 1, the conveyor belt 8, the storage frame 11 and the fixed rollers 12, when in use, the evenly spaced fixed rollers 12 can effectively absorb and disperse vibration energy. When the lathe 1 vibrates during processing, the fixed rollers can play a buffering role, reduce the impact of vibration on the lathe and the conveyor belt 8, and improve the stability and reliability of the equipment. The storage frame 11 is symmetrically arranged with respect to the central axis of the conveyor belt 8, which helps to ensure the balance and stability of the conveyor belt 8 during operation. The symmetrical storage frame can better fix the conveyor belt 8 to prevent it from shifting or shaking during operation.

[0035] Furthermore, the first screw 907 is threadedly connected to the transmission rod 902 through the second connecting rod 908, and the second screw 910 is threadedly connected to the connecting shaft 909 through the second connecting rod 908. Through the arrangement of the first screw 907, the second connecting rod 908, the transmission rod 902, the second screw 910 and the connecting shaft 909, when in use, the threaded connection provides a firm mechanical connection to ensure that the various components will not easily loosen or separate during operation. The threaded connection between the first screw 907 and the second connecting rod 908 and the second screw 910 and the connecting shaft 909 makes the transmission system more stable and reliable when transmitting power and motion.

[0036] Working principle: First, after opening the lathe door 13 through the handle 14, turn on the central controller 2 located on the left side of the lathe 1 to start the parts processing of the entire lathe. The material is placed on the rotating disk 4 and fixed by the three-jaw chuck 5. The height limiting shaft 6 above the rotating disk 4 limits the material from contacting the rotating disk. The material is processed by the cutting robot 3. After processing, the material will be picked up by the picking robot 7 and put into the conveyor belt 8. When the material moves on the conveyor belt 8 and passes through the infrared sensor 919, it will be captured by the infrared sensor 919. The sensor 919 transmits the captured information to the infrared controller 916 through the second line 918. After receiving the information, the infrared controller 916 transmits the signal to the motor 915 through the first line 917, thereby activating the motor 915 to start working. The motor 915 is fixed to one side of the conveyor belt 8 by the fixed motor box 913. The motor 915 drives the crawler belt 914 to rotate, and the crawler belt 914 drives the rotating shaft 911 to rotate. Since the rotating shaft 911 is rotatably connected to the second connecting rod 908, the rotating shaft 911 drives the second connecting rod 908 to rotate. The second connecting rod 908 is rotatably connected to the transmission rod 902, and the second connecting rod 908 drives the transmission rod 902 to perform telescopic movement on the inner wall surface of the fixed block 901. The transmission rod 902 is rotatably connected to the first connecting rod 903, and the transmission rod 902 drives the first connecting rod 903 to move regularly. The first connecting rod 903 is rotatably connected to the blocking rod 904, and the first connecting rod 903 rotates to drive the blocking rod 904 to perform telescopic movement. The sliding shaft 905 below the blocking rod 904 is fixedly connected, and the sliding shaft 905 is located on the inner wall sliding surface of the limit block 906. Dynamic connection limits the movement range of the sliding shaft 905, so the material blocking rod 904 can telescope in a certain range. In this way, the infrared sensor can quickly and accurately detect the workpiece or processing position, triggering the crank-connecting rod mechanism to automatically perform corresponding actions without human intervention, reducing operation time and waiting time, thereby significantly improving production efficiency. The motor model of the conveyor belt 8 is Y132S-4, and the motor model of the motor 915 is L298N. This completes the use process of a material blocking structure based on CNC lathe processing.
