Description

Technical Field

[0001] This utility model relates to the field of automated CNC machine tool production technology, and in particular to a transmission device in an automated CNC machine tool production line. Background Technology

[0002] In automated CNC machine tool production lines, the transmission device is a key component that connects various processing equipment and realizes the flow of materials. Its function is to accurately and efficiently transport the raw materials to the CNC machine tools for processing, and to promptly transfer the semi-finished or finished products to the subsequent processes or storage areas. With the continuous development of the manufacturing industry, the requirements for the production efficiency, processing accuracy and stability of automated CNC machine tool production lines are getting higher and higher. The performance of the transmission device directly affects the operation of the entire production line.

[0003] Currently, some of the conveyor devices commonly used in automated CNC machine tool production lines on the market adopt the traditional belt conveyor method. This method uses a motor to drive the belt to move materials. It has a relatively simple structure and low cost. However, it has obvious defects in terms of transmission accuracy. Materials are prone to deviation during movement, especially when conveying small, high-precision parts. Deviation can lead to inaccurate positioning of parts during processing, which in turn affects the processing quality of subsequent products. Moreover, belt operation does not have a buffering effect. When placing materials for transmission, it cannot buffer the vibration during the material transmission process, making it difficult to provide good protection for the materials.

[0004] Therefore, a transmission device for automated CNC machine tool production lines is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a transmission device for automated CNC machine tool production lines. This device addresses the common problem in existing automated CNC machine tool production line transmission devices on the market, which partially employ traditional belt conveyors. While this method uses a motor to drive the belt to move materials and has a relatively simple structure and low cost, it has significant drawbacks in terms of transmission accuracy. Materials are prone to shifting during movement, especially when conveying small, high-precision parts. This shifting can lead to inaccurate positioning of parts during processing, thus affecting the processing quality of subsequent products. Furthermore, belt operation lacks a buffering effect, failing to cushion vibrations during material transport and thus failing to provide adequate protection for the materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transmission device in an automated CNC machine tool production line, including a rail frame, a controller is provided on the right side of the rail frame, a driving structure is provided inside the rail frame, a base plate is bolted to the top of the driving structure, a buffer mechanism is provided on the top of the base plate, a placement plate is bolted to the top of the buffer mechanism, and a positioning mechanism is provided on the top of the placement plate.

[0007] The positioning mechanism includes a sliding groove formed around the top perimeter of the placement plate. Air cylinders are bolted to the outer perimeter of the placement plate. A push rod is slidably connected inside the air cylinder. The inner side of the push rod passes through the outer side of the placement plate and extends into the sliding groove. A flexible clamp is fixedly connected to the inner side of the push rod. The flexible clamp is slidably connected inside the sliding groove. A matching block is fixedly connected to the outer side of the push rod. A four-way pipe is connected to the outer side of the air cylinder. An air valve pipe is connected to the bottom of the four-way pipe. An infrared sensor is installed on the top of the placement plate.

[0008] Preferably, the buffer mechanism includes fixing sleeves bolted to the four corners of the top of the base plate, and springs are fixedly connected inside the fixing sleeves.

[0009] Preferably, a buffer shell is fixedly connected to the top of the spring, and the top of the buffer shell is bolted to the bottom of the placement plate.

[0010] Preferably, a reinforcing post is fixedly connected inside the fixing sleeve, the reinforcing post is located outside the spring, and the reinforcing post is located at the bottom of the buffer shell.

[0011] Preferably, the driving structure includes a servo motor bolted to the front side inside the rail frame, the servo motor being electrically connected to a controller, a fixed sleeve bolted to the rear side inside the rail frame, a lead screw fixedly connected to the output end of the servo motor, and the rear side of the lead screw being rotatably connected inside the fixed sleeve.

[0012] Preferably, a movable block is threadedly connected to the outer side of the lead screw, the top of the movable block is fixedly connected to the bottom of the base plate, and sliding sleeves are fixedly connected to the four corners of the bottom of the base plate, with the sliding sleeves slidably connected to the outer side of the top of the rail frame.

[0013] Preferably, a rubber pad is adhered to the top of the placement plate, and the surface of the rubber pad is provided with anti-slip texture.

[0014] Preferably, connecting plates are fixedly connected to both sides of the bottom of the movable block, and rollers are rotatably connected to the inner side of the connecting plates, with the bottom of the rollers contacting the bottom side inside the rail frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application sets up a driving structure and a positioning mechanism. The driving structure provides stable power for material transmission, ensuring the high efficiency of material conveying. During this process, when the material is placed on the placement plate, the infrared sensor can quickly sense the material. After the material is detected, high-pressure air is connected to the air valve pipe. The controller controls the air valve pipe to open and air is supplied to the four-way pipe. The push rod in the air cylinder slides inward under the action of air pressure, which drives the flexible clamping plate to slide in the slide groove and clamp the material. This design can automatically adjust the clamping force and position according to the size of the material, effectively avoiding the material from shifting during the transmission process. It ensures that small, high-precision parts can be accurately positioned during processing, greatly improving the transmission accuracy and thus improving the processing quality of subsequent products.

[0017] 2. By setting up a buffer mechanism, this application can effectively buffer the vibration during the material transfer process when the material is placed on the placement plate, thereby reducing the damage to the material caused by vibration. Whether it is a brittle precision part or a part with an easily scratched surface, it can be well protected. At the same time, it reduces the impact of vibration on the stability of the transmission device and the entire production line, extends the service life of the equipment, and ensures the smooth operation of the production line.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] The transmission device in the automated CNC machine tool production line includes a rail frame 1, a controller 2 is provided on the right side of the rail frame 1, a drive structure 3 is provided inside the rail frame 1, a base plate 4 is bolted to the top of the drive structure 3, a buffer mechanism 5 is provided on the top of the base plate 4, a placement plate 6 is bolted to the top of the buffer mechanism 5, and a positioning mechanism 7 is provided on the top of the placement plate 6.

[0027] The positioning mechanism 7 includes a sliding groove 71 formed around the top of the placement plate 6. Air cylinders 72 are bolted to the outer perimeter of the placement plate 6. A push rod 73 is slidably connected inside the air cylinder 72. The inner side of the push rod 73 passes through the outer side of the placement plate 6 and extends into the sliding groove 71. A flexible clamp 74 is fixedly connected to the inner side of the push rod 73. The flexible clamp 74 is slidably connected inside the sliding groove 71. A matching block 75 is fixedly connected to the outer side of the push rod 73. A four-way pipe 76 is connected to the outer side of the air cylinder 72. An air valve pipe 77 is connected to the bottom of the four-way pipe 76. An infrared sensor 78 is provided on the top of the placement plate 6.

[0028] In this embodiment: by setting up a driving structure 3, a buffer mechanism 5, and a positioning mechanism 7, the driving structure 3 operates inside the rail frame 1 under the control of the controller 2, providing stable power for the entire transmission process. It drives the bottom plate 4 bolted to its top to move, thereby causing the buffer mechanism 5, the placement plate 6, and the material on the placement plate 6 installed on the bottom plate 4 to move accordingly, ensuring the high efficiency of material conveying. When the material is placed on the placement plate 6, the infrared sensor 78 on the top of the placement plate 6 will quickly sense the presence of the material and transmit the signal to the controller 2. After receiving the signal, the controller 2 controls the air inlet valve pipe 77 to open, allowing the high-pressure air from outside to pass through the four-way pipe 76. The high-pressure air enters the air cylinder 72, causing the push rod 73 inside the air cylinder 72 to slide inward under the action of air pressure. The flexible clamping plate 74 fixedly connected to the inner side of the push rod 73 also slides inward. The material slides within the grooves 71 around the top of the placement plate 6, clamping it from all sides. Because the push rod 73 has a matching block 75 on its outer side, the sliding distance of the push rod 73 can be automatically adjusted according to the size of the material, thereby changing the clamping force and position of the flexible clamping plate 74. This effectively prevents material deviation during transmission, ensuring precise positioning of small, high-precision parts during processing, improving transmission accuracy, and guaranteeing the processing quality of subsequent products. Simultaneously, during material transmission, the buffer mechanism 5 is installed between the base plate 4 and the placement plate 6, effectively buffering the vibration generated during material transmission. This not only reduces damage to the material caused by vibration, protecting brittle precision parts or easily scratched components, but also reduces the impact of vibration on the transmission device and the stability of the entire production line, extending the equipment's service life and ensuring the smooth operation of the production line.

[0029] Specifically, such as Figure 3 As shown, the buffer mechanism 5 includes a fixing sleeve 51 bolted to the four corners of the top of the base plate 4, and a spring 52 is fixedly connected inside the fixing sleeve 51.

[0030] Specifically, such as Figure 3 As shown, a buffer shell 53 is fixedly connected to the top of the spring 52, and the top of the buffer shell 53 is bolted to the bottom of the placement plate 6.

[0031] Specifically, such as Figure 3 As shown, a reinforcing post 54 is fixedly connected inside the fixed sleeve 51. The reinforcing post 54 is located outside the spring 52 and at the bottom of the buffer shell 53.

[0032] In this embodiment: By setting up a buffer mechanism 5, when the material is transported on the rail frame 1 along with the placement plate 6, once vibration occurs, the fixed sleeve 51 will be the first to be affected by the vibration. Since the spring 52 inside the fixed sleeve 51 is elastic, it can absorb the vibration energy and convert the impact force of the vibration into the elastic potential energy of the spring 52, thereby alleviating the direct impact of the vibration on the placement plate 6. The reinforcing column 54 is located outside the spring 52. On the one hand, it can protect and limit the spring 52, preventing the spring 52 from excessively shifting or twisting during vibration. On the other hand, it can enhance the overall stability and make the buffering process more reliable. The buffer shell 53 connects the spring 52 and the placement plate 6, and transmits the relatively stable support force after the spring 52 is buffered to the placement plate 6, thereby effectively reducing the damage caused by vibration to the material on the placement plate 6. Whether it is a brittle precision part or a part with an easily scratched surface, it can be better protected. At the same time, it also reduces the impact of vibration on other parts of the transmission device, reduces the interference of vibration on the stability of the entire production line, extends the service life of the equipment, and ensures the smooth operation of the production line.

[0033] Specifically, such as Figure 4 As shown, the drive structure 3 includes a servo motor 31 bolted to the front side inside the rail frame 1. The servo motor 31 is electrically connected to the controller 2. A fixed sleeve 32 is bolted to the rear side inside the rail frame 1. A lead screw 33 is fixedly connected to the output end of the servo motor 31. The rear side of the lead screw 33 is rotatably connected inside the fixed sleeve 32.

[0034] Specifically, such as Figure 4 As shown, a movable block 34 is threadedly connected to the outer side of the lead screw 33. The top of the movable block 34 is fixedly connected to the bottom of the base plate 4. Sliding sleeves 35 are fixedly connected to the four corners of the bottom of the base plate 4. The sliding sleeves 35 are slidably connected to the outer side of the top of the rail frame 1.

[0035] In this embodiment: By setting the driving structure 3, when the controller 2 issues a command, the servo motor 31, which is electrically connected to the controller 2, starts to work. The output end of the servo motor 31 drives the lead screw 33 to rotate. Since the lead screw 33 and the moving block 34 are threadedly connected, and the top of the moving block 34 is fixed to the bottom of the base plate 4, the rotation of the lead screw 33 will be converted into the linear movement of the moving block 34 along the lead screw 33, thereby driving the base plate 4 to move. The sliding sleeve 35 is installed at the four corners of the bottom of the base plate 4. It slides on the outer side of the top of the rail frame 1, playing the role of guidance and stable support, ensuring that the base plate 4 will not deviate or shake during the movement, so that the material can be efficiently and accurately transferred in the automated CNC machine tool production line, meeting the material conveying requirements of different processing steps.

[0036] Specifically, such as Figure 2 As shown, a rubber pad 8 is glued to the top of the placement plate 6, and the surface of the rubber pad 8 is provided with anti-slip texture.

[0037] Specifically, such as Figure 5 As shown, connecting plates 9 are fixedly connected to both sides of the bottom of the movable block 34, and rollers 10 are rotatably connected to the inner side of the connecting plates 9. The bottom of the rollers 10 is in contact with the bottom side inside the rail frame 1.

[0038] In this embodiment: by setting rubber pad 8, connecting plate 9 and roller 10, the rubber pad 8 on the top of the placement plate 6 and its anti-slip texture increase the friction between the material and the placement plate 6, making the material more stable on the placement plate 6, further preventing the material from sliding or shifting during the transmission process, which helps to improve the transmission accuracy and ensure the product processing quality. In addition, the roller 10 at the bottom of the moving block 34 contacts the inner bottom side of the rail frame 1. When the moving block 34 moves, its roller 10 rotates, which indirectly makes the moving block 34 drive the base plate 4 to move more smoothly, reducing energy consumption, and also reducing the wear of the moving block 34 and the rail frame 1, extending the service life of the transmission device, and ensuring that the entire transmission process is carried out efficiently and stably.

[0039] Working Principle: In the operation of the transmission device in an automated CNC machine tool production line, the controller 2, as the core control component, plays a crucial coordinating role. When the production line starts, the controller 2 sends a command to the servo motor 31, causing the servo motor 31 to start running. Its output drives the lead screw 33 to rotate. Since the lead screw 33 is threadedly connected to the moving block 34, and the top of the moving block 34 is fixed to the base plate 4, the moving block 34 moves linearly along the lead screw 33, thereby moving the base plate 4. The sliding sleeves 35 at the four corners of the bottom of the base plate 4 are mounted on the guide rail. The top outer sliding mechanism not only serves as a guide but also ensures the stability of the base plate 4's movement, enabling efficient and accurate material transfer within the production line. During this process, when material is placed on the placement plate 6, the infrared sensor 78 on the top of the placement plate 6 quickly senses the material and transmits a signal to the controller 2. Upon receiving the signal, the controller 2 controls the air inlet valve 77 to open, allowing external high-pressure air to enter the air cylinder 72 through the four-way pipe 76. The push rod 73 inside the air cylinder 72 slides inward under air pressure, driving the inner flexible clamping plate. The push rod 74 slides within the grooves 71 around the top of the placement plate 6, clamping the material from all sides. The supporting block 75 on the outside of the push rod 73 can automatically adjust the sliding distance of the push rod 73 according to the size of the material, changing the clamping force and position of the flexible clamping plate 74, effectively preventing material deviation during transmission, ensuring accurate positioning during the processing of small, high-precision parts, improving transmission accuracy and product processing quality. If vibration occurs during material transmission, the fixed sleeve 51, located at the four corners of the top of the base plate 4, is the first to be affected by the vibration. The spring 52 inside absorbs the vibration energy, converting the impact force into elastic potential energy, mitigating the direct impact on the placement plate 6. The reinforcing column 54 is outside the spring 52, which can both protect and limit the spring 52, preventing it from excessively deviating or twisting, and also enhance the overall stability. The buffer shell 53 connects the spring 52 and the placement plate 6, transferring the stable support force after the spring 52 is buffered to the placement plate 6, reducing the damage of vibration to the material, protecting various parts, and reducing the impact of vibration on other components of the transmission device and the stability of the entire production line, extending the service life of the equipment, and ensuring the smooth operation of the production line.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
