Description

Technical Field

[0001] This invention relates to the field of heat treatment conveying technology, and in particular to a conveying device for machining cemented carbide anti-vibration milling cutters. Background Technology

[0002] Carbide anti-vibration end mills are rotary cutting tools used for milling operations. They have one or more cutting teeth and are usually long rod-shaped structures. In the process of manufacturing carbide anti-vibration end mills, multiple heat treatment operations are usually performed to improve their structural strength. Conveying devices are usually set up between multiple heat treatment stations in the workshop to realize the loading and unloading operations of the end mills during the heat treatment process.

[0003] To ensure convenient loading and unloading and enable simultaneous loading and unloading operations at the same point, the conveying device is usually designed as a ring structure. When the conveying direction changes during the use of the ring structure, it is inevitable to use an arc-shaped conveying structure for connection. However, because the arc lengths of the inner and outer sides of the arc-shaped conveying structure are inconsistent, the track length of the outer side is much longer than that of the inner side. This makes it easy for the milling cutter holder to deflect during the use of the arc-shaped conveying structure, affecting the accuracy of the milling cutter being grasped by the heat treatment device during the cyclic conveying process, and thus affecting the overall processing efficiency.

[0004] To address these issues, a conveying device for machining cemented carbide anti-vibration milling cutters is proposed. Summary of the Invention

[0005] The purpose of this invention is to solve the shortcomings of the existing technology where the arc-shaped conveying structure is used for conveying milling cutters during the heat treatment process, which makes the milling cutters prone to deflection during transfer and affects the accuracy of gripping the milling cutters during the heat treatment process. Therefore, this invention proposes a conveying device for machining cemented carbide anti-vibration milling cutters.

[0009] Preferably, a roller is rotatably mounted at the hinge joint between the first hinge rod and the first push plate, and the roller rolls against the outer surface of the baffle. A first electromagnet is fixedly mounted inside the first push plate.

[0010] Preferably, the bottom of the frame is equipped with a plurality of circumferentially distributed ball bearings, which are rolled and embedded in the bottom of the frame.

[0011] Preferably, a downward-opening storage box is fixedly embedded in the bottom of the frame, and a bottom box is slidably installed inside the storage box. A top box is slidably installed inside the bottom box. The sides of the bottom box and the top box are provided with corresponding U-shaped grooves.

A straight spring is fixedly connected between the bottom box and the top box. A first long strip electromagnet that spans the inside of the first conveyor belt and the second conveyor belt is fixedly installed on both the front and rear sides of the conveyor frame.

[0012] Preferably, multiple outwardly extending trays are fixedly installed on the left and right sides of the conveyor frame, and the multiple trays are arranged symmetrically on the left and right.

[0015] Preferably, a through groove is provided in the fixed plate, the third hinge rod is installed in the through groove, and the fourth hinge rod is provided on the upper and lower sides of the second push plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by connecting the meshing first gear and the second gear between the first roller and the second roller on the left and right sides, the first conveyor belt and the second conveyor belt rotate synchronously relative to each other. With the help of the stops of the baffles erected at the front and rear ends of the conveyor frame and the push of the first push assembly set at the front and rear ends, the milling cutter head is circulated on the first conveyor belt and the second conveyor belt. During the circulated conveying process, the milling cutter head moves horizontally and vertically in a straight line and is not easy to deviate. This helps to ensure the stability of the milling cutter head being captured by the heat treatment equipment during the processing and production process, thereby helping to ensure the efficiency of milling cutter processing and production. 2. In this invention, by setting the first pushing component to be completely retracted at the edge of the conveyor frame when not in use, its space occupation is small. Compared with the prior art, which uses an electric push rod to push the milling cutter holder to move laterally, it can effectively reduce the amount of lateral space occupied by the device in the workshop, which is conducive to improving the convenience of the device during installation and use. At the same time, by using the second servo motor to drive the gear plate to rotate at high speed, the connecting plate can be driven to move back and forth at high speed, which is conducive to ensuring the efficiency of the first push plate pushing the milling cutter holder to move laterally and the first push plate resetting. 3. In this invention, by hinged a second hinge rod, which is parallel to the first hinge rod, between the first push plate and the connecting plate, the connecting plate, the first hinge rod, the first push plate, and the second hinge rod form a parallelogram structure, ensuring that the first push plate is always parallel to the connecting plate and that the first push plate is flat and in close contact with the outer surface of the milling cutter holder. Combined with the magnetic attraction connection after the first electromagnet inside the first push plate is energized, this helps to ensure the stability of the milling cutter holder when it is moved laterally by the first push plate. 4. In this invention, by sliding the bottom box and top box inside the storage box and using the elastic support of the straight spring, the bottom of the bottom box is in contact with the first conveyor belt, the second conveyor belt and the top of the tray under normal circumstances. This helps to ensure the stability of the milling cutter holder's position under normal circumstances. At the same time, by rolling the ball bearings at the bottom of the frame, and cooperating with the meshing and reversing of the third gear and the first and second racks, as well as the magnetic attraction of the first and second long electromagnets after they are energized, the bottom of the milling cutter holder only relies on the ball bearings for contact when it moves between the first conveyor belt, the second conveyor belt and the tray. This helps to improve the smoothness of the milling cutter holder's position transfer during the conveying process. 5. In this invention, by symmetrically arranging the pallets on the left and right and placing the second pushing component between the two symmetrical pallets, one second pushing component can act on both pallets to transfer the milling cutter holder. The heat treatment equipment on the left and right sides can share one second pushing component, which helps to reduce the amount of second pushing component used by the device and reduces the manufacturing and use costs of the device to a certain extent. 6. In this invention, the second pushing component is retracted in the middle of the conveyor frame when it is not activated. Its overall structure is a longitudinally flat structure, which occupies little lateral space and helps to save space in the workshop. At the same time, during the activation of the second pushing component, the rotating shaft is directly driven by the third servo motor to control the swing of the third hinge rod, so that the third hinge rod can be quickly driven to swing back and forth, which helps to improve the efficiency of the milling cutter head in transferring between the first conveyor belt, the second conveyor belt and the pallet.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example: This example provides a conveying device for machining carbide anti-vibration end mills. See [link to example]. Figure 1 - Figure 12 Specifically, the system includes a conveyor frame 1, with multiple vertically arranged support legs 101 mounted on its bottom. A first roller 102, symmetrically arranged front to back, is mounted on the left side of the conveyor frame 1. A first conveyor belt 103, located on the left side of the conveyor frame 1, is sleeved between two of the first rollers 102. A second roller 104, symmetrically arranged front to back, is mounted on the right side of the conveyor frame 1. A second conveyor belt 105, located on the right side of the conveyor frame 1, is sleeved between two of the second rollers 104, and is arranged side-by-side with the first conveyor belt 103. A first servo motor 106 is fixedly mounted on the conveyor frame 1, and a coaxially arranged [unclear - possibly a component or mechanism] is fixedly mounted at the end of the second roller 104 at the front end. A first gear 107 is mounted on the conveyor frame 1, and a second gear 108 is rotatably connected to the lower part of the first gear 107. A transmission belt 109 is connected between the second gear 108 and the first roller 102 located at the front end. Vertical baffles 2 are fixedly installed at the front and rear ends of the conveyor frame 1. Multiple milling cutter holders 3 are placed on the first conveyor belt 103 and the second conveyor belt 105. The milling cutter holder 3 includes a frame 301 with a square structure. Multiple vertical slots 302 are evenly opened in the frame 301. Carbide anti-vibration milling cutters are vertically inserted into the slots 302. A first pushing component 4 is installed on the left front end and the right rear end of the conveyor frame 1.

[0021] When using this device, the operator installs it longitudinally on the workshop floor and evenly distributes the heat treatment equipment for machining carbide anti-vibration milling cutters on both sides of the device. Then, the operator connects the device to an external power supply, providing power. During operation, the first servo motor 106 mounted on the conveyor frame 1 is energized and starts, driving the second roller 104, which is connected to its drive shaft, to rotate. During the rotation of the second roller 104, the second conveyor belt 105 rotates, conveying the milling cutter holder 3 placed on it. The rotation of the second roller 104 at the front end drives the... The first gear 107, which is fixed coaxially, rotates. Then, through the meshing and reversal of the first gear 107 and the second gear 108, and the transmission connection of the transmission belt 109, the first roller 102 located at the front end rotates in the opposite direction to the second roller 104. During the rotation of the first roller 102, it will drive the first conveyor belt 103 to rotate synchronously, and transport the milling cutter holder 3 placed on the first conveyor belt 103. The rotation direction of the first conveyor belt 103 located on the left is opposite to the rotation direction of the second conveyor belt 105 located on the right. The second conveyor belt 105 transports the milling cutter holder 3 backward, and the first conveyor belt 103 transports the milling cutter holder 3 forward.

[0022] By vertically setting baffles 2 at both ends of the conveyor frame 1, the milling cutter holder 3 moving to the ends of the first conveyor belt 103 and the second conveyor belt 105 can be blocked, preventing the milling cutter holder 3 from falling off the front end of the first conveyor belt 103 and the rear end of the second conveyor belt 105 during the conveying process. When the milling cutter holder 3 is conveyed to the rear end of the conveyor frame 1 by the second conveyor belt 105, the first pushing component 4 installed on the right side of the rear end of the conveyor frame 1 is activated, pushing the milling cutter holder 3 placed at the top rear end of the second conveyor belt 105 laterally onto the left side of the first conveyor belt 103. When the milling cutter holder 3 is conveyed to the front end of the conveyor frame 1 by the second conveyor belt 105, the first pushing component 4 installed on the left side of the front end of the conveyor frame 1 is activated, pushing the milling cutter holder 3 placed at the top front end of the first conveyor belt 103 laterally onto the right side of the second conveyor belt 105. With the help of the opposite rotation of the first conveyor belt 103 and the second conveyor belt 105, and the pushing of the two first pushing components 4, the milling cutter is driven to move. The milling cutter holder 3 is cyclically conveyed by the device. During the conveying process, the milling cutter holder 3 loaded with milling cutters can be captured by the heat treatment equipment set on the left and right sides of the device as needed. Then, the robotic arms in the heat treatment equipment grab the milling cutters loaded in the milling cutter holder 3 one by one for heat treatment. After heat treatment, the milling cutters are put back into the milling cutter holder 3 by the robotic arms. After all the milling cutters in the entire milling cutter holder 3 have been processed into milling cutters, the milling cutter holder 3 loaded with milling cutters is transferred back to the first conveyor belt 103 or the second conveyor belt 105 and is conveyed by the device again. The operator places the milling cutter holder 3 loaded with unprocessed milling cutters on the second conveyor belt 105 from the front end of the device, and removes the milling cutter holder 3 loaded with heat-treated milling cutters from the first conveyor belt 103 from the front end of the device. Through the cyclic conveying of the milling cutter holder 3 by the device, the loading and unloading operations of the milling cutter holder 3 can be carried out at the same position at the front end of the device, which helps to improve the convenience of loading and unloading.

[0023] In the prior art, taking the conveying of the milling cutter holder 3 in the opposite direction by the first conveyor belt 103 and the second conveyor belt 105 in this invention as an example, in order to achieve the cyclic conveying of the milling cutter holder 3, semi-circular conveying structures are usually provided at the front and rear ends of the first conveyor belt 103 and the second conveyor belt 105. The semi-circular conveying structure is usually composed of conveying rollers arranged along a semi-circular trajectory. By rotating the conveying rollers, the milling cutter holder 3 located at the back end of the second conveyor belt 105 is transferred to the back end of the first conveyor belt 103, or the milling cutter holder 3 located at the front end of the first conveyor belt 103 is transferred to the front end of the second conveyor belt 105. When the above structure cyclically conveys the milling cutter holder 3, due to the inner and outer sides of the semi-circular conveying structure... The inconsistent side conveying lengths mean that during the movement of the milling cutter holder 3, the trajectory length conveyed by the outer side of the semi-circular conveying structure is much longer than the trajectory length conveyed by the inner side of the semi-circular conveying structure. Since the rotational speeds of the inner and outer ends of each conveying roller are consistent, the milling cutter holder 3 is prone to skewness when the semi-circular conveying structure transfers it. This affects the accuracy and stability of the transfer of the milling cutter holder 3 from the first conveyor belt 103 to the second conveyor belt 105, and from the second conveyor belt 105 to the first conveyor belt 103. Consequently, the milling cutter holder 3 is prone to skewness when transferring between the first and second conveyor belts 103 and 105, affecting the accuracy of the milling cutter holder 3 when it is grasped by the heat treatment equipment during the conveying process.

[0024] In this application, by means of the lateral pushing of the first pushing component 4, the position of the milling cutter holder 3 is transferred at the ends of the first conveyor belt 103 and the second conveyor belt 105. The conveying direction of the milling cutter holder 3 can be flexibly changed. Combined with the rotational conveying in opposite directions of the first conveyor belt 103 and the second conveyor belt 105, the milling cutter holder 3 can be cyclically conveyed. When the milling cutter holder 3 is transferred at the ends of the first conveyor belt 103 and the second conveyor belt 105, it will not be deflected due to the inconsistent conveying speeds of the inner and outer sides. This can ensure the stability of the cyclic conveying of many milling cutter holders 3 between multiple heat treatment equipment.

[0025] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the first pushing assembly 4 includes a slide 401 slidably mounted on the edge of the conveyor frame 1, and a connecting plate 402 is fixedly mounted on the top of the slide 401. A first hinge rod 403 is hinged to the side of the connecting plate 402 near the baffle 2, and a torsion spring 404 is installed at the hinge point between the first hinge rod 403 and the connecting plate 402. A first push plate 405 is installed at the end of the first hinge rod 403 away from the connecting plate 402. A third rack 408 is fixedly mounted on the bottom of the slide 401. A second servo motor 409 is fixedly mounted on the conveyor frame 1, and a gear plate that meshes with the third rack 408 is coaxially fixed on the drive shaft of the second servo motor 409.

[0026] During operation, when the first pushing component 4 is not activated, it is completely retracted at the edge of the conveyor frame 1 away from the first conveyor belt 103 and the second conveyor belt 105. The first pushing component 4, installed on the left front end of the conveyor frame 1, is correspondingly positioned to the baffle 2. The first pushing component 4, installed on the right rear end of the conveyor frame 1, is also correspondingly positioned to the baffle 2. When the milling cutter holder 3 moves to the front end of the first conveyor belt 103 and the rear end of the second conveyor belt 105, and needs to be transferred to the other side of the conveyor belt, the first pushing component 4 will be activated. During the activation process, the second servo motor 409 installed on the conveyor frame 1 is energized and starts, driving the gear plate fixed coaxially with its drive shaft to rotate. Then, with the help of the meshing of the gear plate and the third rack 408, the slide 401 is driven to move the connecting plate 402 towards the corresponding baffle 2. During the movement, under the obstruction of the corresponding baffle 2, the first pushing component 401 is driven to move the connecting plate 402 towards the corresponding baffle 2. When the first hinge rod 403 deflects, it overcomes the elastic support of the torsion spring 404, causing the torsion spring 404 to be in a compressed state. When the connecting plate 402 moves into place, the first hinge rod 403, which was originally close to 180° with the connecting plate 402, deflects to a state perpendicular to the connecting plate 402. During the deflection of the first hinge rod 403, it drives the first push plate 405 connected to the end of the first hinge rod 403 to move laterally along the baffle 2. Under the movement of the first push plate 405, the milling cutter holder 3 is pushed from the rear end of the second conveyor belt 105 to the rear end of the first conveyor belt 103, or from the front end of the first conveyor belt 103 to the front end of the second conveyor belt 105, thus realizing the transfer operation of the milling cutter holder 3 at the ends of the first conveyor belt 103 and the second conveyor belt 105.

[0027] After the first pusher plate 405 pushes the milling cutter holder 3 from one side of the conveyor belt to the other side, the second servo motor 409 quickly starts in the reverse direction, driving the gear plate to rotate in the reverse direction, causing the slide 401 to move in the reverse direction and reset. The slide 401 drives the connecting plate 402 away from the corresponding baffle 2. During this process, the torsion spring 404 installed at the hinge position between the connecting plate 402 and the first hinge rod 403 is gradually released. Under the elastic support of the torsion spring 404, the first hinge rod 403 moves in the reverse direction and pulls the first pusher plate 405 back to its initial state, retracting to the edge position of the conveyor frame 1. When the first pusher assembly 4 is retracted to the edge position, it will not obstruct the milling cutter holder 3 conveyed on the first conveyor belt 103 and the second conveyor belt 105. The forward and backward movement of 02, with the blocking of baffle 2 and the elastic reset of torsion spring 404, drives the first hinge rod 403 to deflect, causing the first push plate 405 to move left and right, pushing the milling cutter holder 3 to transfer. Under normal circumstances, the first push component 4 is extremely narrowly folded into the side position of the conveyor frame 1, occupying little space. Compared with the existing technology of pushing the milling cutter holder 3 to transfer laterally by electric push rod, it can effectively reduce the lateral space occupied by the device in the workshop, which is conducive to improving the convenience of the device during installation and use. In addition, with the help of the second servo motor 409 to drive the gear plate to rotate at high speed, it can drive the connecting plate 402 to move back and forth at high speed, ensuring the efficiency of the first push component 4 in pushing the milling cutter holder 3 laterally and the reset of the first push component 4.

[0028] The first push plate 405 is hinged to the first hinge rod 403. The first push plate 405 is parallel to the connecting plate 402. The end of the first push plate 405 away from the first hinge rod 403 is hinged to the connecting plate 402 with a second hinge rod 406, which is parallel to the first hinge rod 403. When the device is in use, the second hinge rod 406, which is parallel to the first hinge rod 403, is hinged between the first push plate 405 and the connecting plate 402. This allows the connecting plate 402, the first hinge rod 403, the first push plate 405, and the second hinge rod 406 to form a parallelogram structure. Under the hinge, when the first hinge rod 403 deflects and drives the first push plate 405 to move laterally, it ensures that the first push plate 405 is always parallel to the connecting plate 402. The first push plate 405 and the outer surface of the milling cutter holder 3 remain flat and in contact, which helps to ensure the stability of the milling cutter holder 3 when it is moved laterally by the first push plate 405.

[0029] A roller 407 is rotatably mounted at the hinge of the first hinge rod 403 and the first push plate 405, and the roller 407 rolls against the outer surface of the baffle 2. A first electromagnet is fixedly installed inside the first push plate 405. When the device is in use, by rotatably mounting the roller 407 at the hinge position of the first hinge rod 403 and the first push plate 405, the rolling contact between the roller 407 and the baffle 2 ensures that the first hinge rod 403 is blocked by the baffle 2, thus ensuring the smooth and stable deflection of the first hinge rod 403. When the first push plate 405 moves laterally to push and transfer the milling cutter holder 3, the first electromagnet installed inside the first push plate 405 is energized and activated. The frame 301 is made of iron material. With the help of the magnetic attraction of the frame 301 after the first electromagnet is energized, the connection between the first push plate 405 and the frame 301 can be strengthened, which is beneficial to ensuring the stability of the milling cutter holder 3 when it is transferred at the ends of the first conveyor belt 103 and the second conveyor belt 105.

[0030] In the specific implementation process, such as Figure 4 , Figure 11 and Figure 12 As shown, a plurality of ball bearings 303 are installed around the bottom of the frame 301, and the ball bearings 303 are rolled and embedded in the bottom of the frame 301. When the device is in use, the numerous ball bearings 303 that can roll flexibly are installed around the bottom of the frame 301. With the help of the rolling connection of the ball bearings 303, the frictional resistance between the bottom of the frame 301 and the top surface of the first conveyor belt 103 and the second conveyor belt 105 when the milling cutter holder 3 moves laterally can be effectively reduced, which is conducive to improving the smoothness of the milling cutter holder 3 when it moves laterally between the first conveyor belt 103 and the second conveyor belt 105.

[0031] A downward-opening storage box 304 is fixedly embedded in the bottom of the frame 301, and a bottom box 305 is slidably installed inside the storage box 304. A top box 306 is slidably installed inside the bottom box 305. U-shaped grooves 307 are provided on the sides of the bottom box 305 and the top box 306 respectively. A third gear 308 is rotatably installed on the inner end wall of the storage box 304 and is provided in the U-shaped groove 307. A first rack 309 that meshes with one side of the third gear 308 is fixedly installed on the bottom box 305, and a second rack 310 that meshes with the other side of the third gear 308 is fixedly installed on the top box 306. A straight spring 311 is fixedly connected between the bottom box 305 and the top box 306. A first long strip electromagnet 5 that spans the interior of the first conveyor belt 103 and the second conveyor belt 105 is fixedly installed on both the front and rear sides of the conveyor frame 1.

[0032] In normal operation, the device, supported by the elasticity of the straight spring 311, keeps the bottom box 305 and top box 306, which are positioned vertically, tending to move away from each other. At this time, the bottom of the bottom box 305 is tightly fitted with the tops of the first conveyor belt 103 and the second conveyor belt 105, increasing the actual contact area between the bottom of the frame 301 and the tops of the first and second conveyor belts 103 and 105. This ensures the stability of the milling cutter holder 3 as it is conveyed forward by the first conveyor belt 103 and backward by the second conveyor belt 105. The bottom box 305 is made of wear-resistant plastic, and the top box 306 is made of iron. When the milling cutter holder 3 needs to be moved to the end of the first conveyor belt 103 and the second conveyor belt 105, the first elongated electromagnet 5 installed at the end of the conveyor frame 1 inside the first conveyor belt 103 and the second conveyor belt 105 is energized and activated. Magnetic adsorption occurs at the top. Under the magnetic attraction of the first long strip electromagnet 5, the top box 306 inside the milling cutter holder 3 that needs to be transferred moves downward. During the downward movement of the top box 306, the second rack 310 moves downward synchronously. With the help of the meshing and reversing of the third gear 308, the first rack 309 on the other side drives the bottom box 305 to move upward. In this state, due to the upward movement of the bottom box 305, its bottom separates from the top of the first conveyor belt 103 and the second conveyor belt 105. The milling cutter holder 3 only contacts the first conveyor belt 103 and the second conveyor belt 105 by the rolling of the ball bearings 303. The above structure makes the milling cutter holder 3 stable when it is transported back and forth by the device, and the milling cutter holder 3 moves smoothly between the first conveyor belt 103 and the second conveyor belt 105, which improves the flexibility of the device in actual use to a certain extent.

[0033] In the specific implementation process, such as Figure 7 , Figure 9 and Figure 10 As shown, multiple outwardly extending trays 6 are fixedly installed on the left and right sides of the conveyor frame 1, and the multiple trays 6 are arranged symmetrically on the left and right. A second pushing component 7 is installed between two symmetrical trays 6, located in the middle of the first conveyor belt 103 and the second conveyor belt 105. A second long strip electromagnet 8 extending into the conveyor frame 1 is fixedly installed at the bottom of the tray 6. When the device is in use, the multiple trays 6 installed on the left and right sides of the conveyor frame 1 are connected to the corresponding heat treatment equipment. The trays 6 are used as the connection platform between the conveyor frame 1 and the heat treatment equipment. A label is affixed to the outer surface of the frame 301. A card reader for label recognition is installed on the conveyor frame 1. By recognizing the label information through the card reader, the milling cutter holder 3 can be identified. A vision probe is also installed on the conveyor frame 1 to detect the heat treatment status of the milling cutters in each milling cutter holder 3, realizing visual inspection during the milling cutter conveying process. The surrounding conveying structure greatly improves the detection range of a single vision probe, which helps to reduce the cost of visual inspection and intelligent heat treatment conveying of milling cutters.

[0034] When the heat treatment equipment needs to capture the milling cutter holder 3, the second pushing component 7 installed on the conveyor frame 1 is powered on and activated. The second pushing component 7 pushes the required milling cutter holder 3 onto the corresponding tray 6. Then, the robot on the heat treatment equipment can grab or place the milling cutter in the milling cutter holder 3. After the milling cutter in the milling cutter holder 3 has finished processing, the milling cutter holder 3 can be transferred from the conveyor frame 1 back to the first conveyor belt 103 and the second conveyor belt 105 through the second pushing component 7. During the use of this device, multiple trays 6 on the left and right sides are symmetrically arranged, and the corresponding second pushing component 7 is located in the middle of the first conveyor belt 103 and the second conveyor belt 105, and is arranged in correspondence with the symmetrical trays 6 on the left and right sides. The second pushing component 7 can transfer the milling cutter from the first conveyor belt 103 and the second conveyor belt 105 on both sides to the trays 6 on the left and right sides respectively. With the above structural arrangement, the symmetrical heat treatment equipment on the left and right sides can share a second pushing component 7, which helps to reduce the amount of second pushing component 7 used by the device and can effectively reduce the manufacturing and use costs of the device.

[0035] When the milling cutter holder 3 is driven by the second pushing component 7 to move from the top of the first conveyor belt 103 and the second conveyor belt 105 to the tray 6, or from the tray 6 to the top of the first conveyor belt 103 and the second conveyor belt 105, the second elongated electromagnet 8 installed at the bottom of the tray 6 is energized and started. After the second elongated electromagnet 8 is energized and started, it will generate a magnetic attraction on the top box 306, just like the first elongated electromagnet 5, driving the bottom box 305 to move upward, ensuring the smooth transfer of the milling cutter holder 3 between the top of the first conveyor belt 103 and the second conveyor belt 105 and the tray 6.

[0036] In the specific implementation process, such as Figure 5 and Figure 6 As shown, the second pushing assembly 7 includes a fixed plate 701 fixedly installed on the conveyor frame 1, and a vertically arranged rotating shaft 702 is rotatably installed inside the fixed plate 701. A third servo motor 703 is fixedly installed at the bottom of the conveyor frame 1, and the drive shaft of the third servo motor 703 is connected to the rotating shaft 702. A longitudinally arranged third hinge rod 704 is fixedly connected to the rotating shaft 702, and a second push plate 705 is hinged to the end of the third hinge rod 704 away from the rotating shaft 702. A second electromagnet is fixedly installed inside the second push plate 705. When the device is in use, the second pushing assembly 7 is folded in the middle position of the conveyor frame 1 when it is not activated. Its overall structure is a longitudinally flat structure, which occupies little lateral space and helps to save space in the workshop.

[0037] When the second pushing component 7 is activated to transfer the milling cutter holder 3 onto the tray 6, the third servo motor 703 installed at the bottom of the conveyor frame 1 is energized and starts, driving the rotating shaft 702 connected to its drive shaft to rotate. During the rotation of the rotating shaft 702, the third hinge rod 704 swings. During the swing of the third hinge rod 704, the second push plate 705 connected to the end of the third hinge rod 704 moves. During this process, the second electromagnet installed in the second push plate 705 is energized and starts. With the help of the magnetic attraction generated after it is energized, the second push plate 705 is stably connected to the frame 301 in the corresponding milling cutter holder 3. Then, during the swing of the third hinge rod 704, the milling cutter holder 3 is moved from the top of the first conveyor belt 103 and the second conveyor belt 105 onto the tray 6. The third hinge rod 704 can swing to the left or to the right. When the third hinge rod 704 swings to the left, it moves the milling cutter holder 3 on the first conveyor belt 103 onto the left side of the tray 6. When the third hinge rod 704 swings to the right, it moves the second push plate 705 connected to the end of the third hinge rod 704. The milling cutter holder 3 on the second conveyor belt 105 is driven to the right tray 6. After the milling cutter holder 3 is transferred to the tray 6, the second push assembly 7 quickly resets. During the reset process, the second electromagnet in the second push plate 705 disconnects from the magnetic grip of the frame 301. When it is necessary to transfer the milling cutter holder 3 on the tray 6 back to the first conveyor belt 103 and the second conveyor belt 105, the second push assembly 7 swings to the left or right to the corresponding tray 6 in an idle state. Then, the second electromagnet in the second push plate 705 is energized to connect the milling cutter holder 3. During the reset return process, the milling cutter holder 3 is driven to the first conveyor belt 103 and the second conveyor belt 105. During the start-up of the second push assembly 7, since the rotating shaft 702 that controls the swing of the third hinge rod 704 is directly driven by the third servo motor 703, the third hinge rod 704 can be quickly driven to swing back and forth, which is beneficial to improving the efficiency of the transfer of the milling cutter holder 3 between the first conveyor belt 103, the second conveyor belt 105 and the tray 6.

[0038] The second push plate 705, the third hinge rod 704, and the fixed plate 701 are on the same straight line. A fourth hinge rod 706 is hinged between the end of the second push plate 705 away from the third hinge rod 704 and the fixed plate 701. The length of the third hinge rod 704 is the same as the length of the fourth hinge rod 706. A through groove 707 is provided in the fixed plate 701, and the third hinge rod 704 is installed in the through groove 707. The fourth hinge rod 706 is located on the upper and lower sides of the second push plate 705. When the device is in use, the fixed plate 701, the third hinge rod 704, the second push plate 705, and the fourth hinge rod 706 are on the same straight line. During the swinging and unfolding process, the fixed plate 701, the third hinge rod 704, the second push plate 705, and the fourth hinge rod 706 are on the same straight line. The connecting rod 704, the second push plate 705, and the fourth hinge rod 706 form a parallelogram structure, ensuring that the second push plate 705 is always parallel to the fixed plate 701, thus guaranteeing the stability of the second push plate 705 in grasping the milling cutter holder 3. By installing the third hinge rod 704 in the through slot 707 opened on the inner side of the fixed plate 701 and setting the fourth hinge rod 706 on the upper and lower sides of the second push plate 705, the third hinge rod 704 will not interfere with the fourth hinge rod 706 during the swinging process. This helps to ensure the stability of the device when efficiently transferring the milling cutter holder 3 on the first conveyor belt 103 and the second conveyor belt 105 through the second pushing assembly 7.

[0039] Specifically, the working principle and operation method of this invention are as follows: The first servo motor 106, mounted on the conveyor frame 1, is energized and starts, driving the second roller 104, which is connected to its drive shaft, to rotate. This, in turn, drives the top of the second conveyor belt 105 to rotate backward. Through the meshing of the first gear 107 and the second gear 108, the first roller 102 is driven to rotate in the opposite direction, causing the top of the first conveyor belt 103 to rotate forward. The milling cutter holder 3, loaded with milling cutters, is stacked on the first conveyor belt 103 or the second conveyor belt 105 and moves under the rotation of the first conveyor belt 103 and the second conveyor belt 105. When the milling cutter holder... When the milling cutter holder 3 is conveyed to the front end of the first conveyor belt 103 or the rear end of the second conveyor belt 105, the first pushing component 4 installed at the corresponding position is activated, pushing the milling cutter holder 3 to the conveyor belt on the other side, realizing the cyclic conveying of the milling cutter holder 3. During the cyclic conveying process, the second pushing component 7 installed in the middle position of the conveyor frame 1 can transfer the milling cutter holder 3 conveyed on the first conveyor belt 103 and the second conveyor belt 105 to the corresponding tray 6 according to the processing requirements. During the milling cutter heat treatment process, the loading and unloading conveying operation of the milling cutter holder 3 is completed.
