Description

Technical Field

[0001] This application relates to the field of bar processing, and in particular to a bar feeding device. Background Technology

[0002] A bar feeder is an auxiliary device specifically designed to supply long bars to machine tools, facilitating the processing of these long bars, as shown in patent publication number CN113415631B.

[0003] However, the bar feeder disclosed in the aforementioned patent is only suitable for conveying bars with a certain degree of rigidity, such as bars with a diameter of 3mm or more. For bars with a smaller diameter, such as less than 1mm, the material is soft and lacks rigidity. Using the bar feeder disclosed in the aforementioned patent will cause many problems. For example, the small bars have less weight and cannot slide smoothly down the upper surface of the feeding plate 12 to the side near the feeding trough 2 under the action of frictional resistance. Moreover, the small bars will bend arbitrarily on the feeding plate 12, making it impossible to ensure that all the top hooks 11 can hook the bars, thus affecting the bar feeding.

[0004] For example, the material gripping mechanism 6 disclosed in the aforementioned patent is prone to bending the small rod during the clamping process, which makes it impossible for the material conveying rod push plug to be smoothly inserted and fixedly connected with the rod.

[0005] Furthermore, the synchronization mechanism disclosed in the aforementioned patent uses an encoder to achieve synchronized movement between the bar and the machine tool. Due to the inherent error of the encoder, the synchronization accuracy is limited. For bars with larger diameters, the synchronization error generated by the encoder has little impact on the bar's machining accuracy. However, for bars with smaller diameters, such as less than 1 mm, the synchronization error generated by the encoder has a significant impact on the machining accuracy of such bars, because the thinner the bar, the higher the machining accuracy requirement.

[0006] Therefore, existing bar feeders can only be used to convey bars with a certain rigidity, which are not easy to bend and have a large diameter. They cannot convey bars that are soft, easy to bend and have a small diameter. Hence, this application was designed. Summary of the Invention

[0007] In order to facilitate the smooth feeding of small-diameter, easily bent bars, this application provides a bar feeding device.

[0008] In one aspect of this disclosure, a bar feeding device is provided, comprising: The feeding device has multiple sets of spaced-apart conveying plate groups. Each set of conveying plate groups includes a fixed plate and a movable plate spaced-apart. The upper surfaces of the fixed plate and the movable plate are provided with multiple toothed grooves spaced apart along the bar conveying direction. The fixed plate is fixedly installed. The movable plate is rotatably mounted with multiple eccentric wheels. The eccentric wheels are mounted on a rotating shaft. The rotating shaft is connected to a driving element. The eccentric wheels are configured such that the driving element drives the rotating shaft to rotate, thereby causing the eccentric wheels to rotate. The eccentric wheels then cause the movable plate to perform a circular translation relative to the fixed plate in the vertical plane. When the movable plate is translated to its highest position, the lowest point of the toothed groove of the movable plate is above the highest point of the toothed groove of the fixed plate. When the movable plate is translated to its lowest position, the highest point of the toothed groove of the movable plate is below the lowest point of the toothed groove of the fixed plate. The conveying device has: The slide rail has a material conveying trough one, a material dropping hole and a material conveying trough two arranged sequentially along the bar conveying direction. The material conveying trough one is located below the material feeding end of the material conveying plate group. The bar that slides down from the material feeding end of the material conveying plate group falls into the material conveying trough one. Slider 1, which can move on a slide rail; The drive mechanism is connected to slider one and is used to drive slider one to move on the slide rail; A transfer mechanism 1 is connected to a material conveying component. The transfer mechanism 1 is configured to drive the material conveying component into a material conveying trough 1 and connect it to a slider 1, and to drive the material conveying component away from the material conveying trough 1 and separate it from the slider 1. The clamping mechanism is configured to clamp the bar at the discharge hole, so as to cooperate with the slider to complete the connection and separation of the conveying component and the bar; The second transfer mechanism is connected to a cover plate, and the second transfer mechanism is configured to drive the cover plate in and out of the second conveying trough.

[0009] By adopting the above technical solution, the feeding device supplies small-diameter, easily bendable bars to the conveying device. The feeding device can realize the smooth and orderly conveying of small bars, and can also drive the small bars forward or backward to meet the needs of continuous feeding for a long time. The cover plate prevents the bars from bending and leaving the conveying trough during the conveying process, ensuring the smooth conveying operation. The clamping mechanism clamps the bars from both the top and bottom, ensuring that the conveying rod push plug can be smoothly inserted and fixedly connected with the bars.

[0010] Preferably, the feeding device further includes: The storage container is positioned higher than the conveyor plate assembly; A guide component has an inclined upper surface. The high end of the upper surface of the guide component is configured to receive the bar material falling from the storage container, and the low end of the upper surface of the guide component is configured to allow the bar material sliding obliquely downward along the upper surface of the guide component to slide away from the low end and fall into the tooth grooves corresponding to multiple sets of conveyor plates.

[0011] By adopting the above technical solution, the bars to be fed can be stored in a storage container. Then, manual labor or robotic arms or other equipment will push the bars one by one to the guide components. The guide components will guide the bars to fall smoothly, orderly and accurately into the corresponding toothed grooves of multiple sets of conveyor plates, so as to achieve uniform and continuous feeding of the bars.

[0012] Preferably, the driving mechanism includes a transmission wheel and a transmission belt sleeved on the transmission wheel, and the slider is connected to the transmission belt. The slider is equipped with a roller, which is rotatably connected to the slide rail; The slider is provided with an upwardly protruding limiting component. The feeding component includes a feeding rod, a connecting plate, and a connecting block fixedly connected to the feeding rod and the connecting plate. The end of the feeding rod away from the connecting block is provided with a plug. When the transfer mechanism drives the feeding rod into the feeding trough, the connecting plate and the limiting component are detachably plugged in. When the transfer mechanism drives the feeding rod away from the feeding trough, the connecting plate and the limiting component are separated.

[0013] By adopting the above technical solution, the material conveying components and the slider can be quickly connected or separated, thereby smoothly completing the bar conveying operation.

[0014] Preferably, the transfer mechanism includes: The second rotating shaft has several hook rods and connecting parts arranged at intervals along its axial direction, and the hook rods hook onto the conveying rod; A limiting block is fixedly connected to a connecting piece two. The limiting block is provided with a sliding groove. The connecting plate is provided with a slider two. The slider two is slidably connected to the sliding groove. The sliding direction is the bar conveying direction. Push-pull component one is connected to rotating shaft two via connecting rod one, and is used to drive rotating shaft two to rotate.

[0015] By adopting the above technical solution, the push-pull component 1 drives the rotating shaft 2 to rotate, and then the connecting component 2 drives the limiting block to rotate around the rotating shaft 2. With the help of the limiting block, the connecting plate moves synchronously, so that the material conveying component can smoothly leave the material conveying trough 1. The setting of the slider 2 and the trough does not affect the slider 1 from driving the connecting plate to slide along the material conveying trough 1 and separate from the limiting block, and from driving the connecting plate to reconnect with the limiting block.

[0016] Preferably, the second transfer mechanism includes: Connector 1 is fixedly connected to shaft 2, and mounting plate is fixedly connected to connector 1; Lifting component one is fixedly connected to the mounting plate, and the cover plate is connected to the movable end of lifting component one; There are multiple cover plates, which are arranged in a straight line along the length of the feed trough.

[0017] By adopting the above technical solution, the push-pull component 1 drives the rotating shaft 2 to rotate, which in turn drives the mounting plate to move closer to or away from the material conveying trough 2. When it is necessary to block the material conveying trough 2, the lifting component 1 can be controlled to drive the cover plate to descend, which can prevent the bar from bending and leaving the material conveying trough 2 during the conveying process, and ensure that the material conveying work is carried out smoothly. At the same time, the lifting component 1 drives the cover plate to rise, providing a channel for the sliding of the slider 1 and the connecting plate, avoiding the cover plate from blocking the sliding of the slider 1 and the connecting plate to push the bar to move.

[0018] Preferably, the bar feeding device further includes a connecting and separating mechanism, the connecting and separating mechanism comprising: Push-pull component two, the pushing-pull direction is parallel to the length direction of feed trough one; Link two has one end hinged to the movable end of push-pull component two, and the other end fixedly connected to a plug-in component, which is vertically and detachably plugged into the connecting plate; The second lifting component has a movable end connected to a third slider, which is slidably connected to the plug-in component, and the sliding direction is the same as the pushing and pulling direction of the second lifting component.

[0019] By adopting the above technical solution, the connection and separation of the rod and the plug can be achieved by using the connection and separation mechanism in conjunction with the clamping mechanism.

[0020] Preferably, the bar feeding device further includes a synchronization mechanism, the synchronization mechanism comprising: A drive shaft, on which the drive wheel is mounted; The second transmission wheel and the electromagnetic clutch are mounted on the transmission shaft. The electromagnetic clutch is configured to control the second transmission wheel and the transmission shaft to be connected or disconnected in transmission. A third drive wheel is spaced apart from the second drive wheel along the bar conveying direction, and a second drive belt is fitted on both the second and third drive wheels. The slide bar is set parallel to the direction of bar conveying and is connected to the second transmission belt.

[0021] By adopting the above technical solution, an electromagnetic clutch is used to replace the encoder to improve the synchronization accuracy of the synchronization mechanism, thus meeting the requirements for high machining accuracy of small bars.

[0022] Preferably, the bar feeding equipment further includes a positioning detection mechanism, which includes: The lifting component has a mounting piece connected to its movable end; The baffle is located on the discharge path of the second conveying trough and is hinged to the mounting component; Separable sensing device, suitable for separating from the baffle and generating sensing signal.

[0023] By adopting the above technical solution, compared with photoelectric sensing detection methods, the mechanical positioning detection mechanism in this embodiment not only has high detection accuracy and can detect small diameter rods, but also has low cost, long service life, and stable and reliable performance.

[0024] Preferably, a receiving box is provided below the material discharge hole.

[0025] By adopting the above technical solution, the receiving box is used to centrally receive and collect the tailings of the bar stock, which facilitates recycling and processing.

[0026] Preferably, the upper surface of the fixed plate and the movable plate has a feeding slope at the feeding end, and a guide frame is provided between the feeding device and the conveying device, so that the bar sliding down from the feeding slope falls into the conveying trough along the guide frame.

[0027] By adopting the above technical solution and adding a guide frame, the bar material is ensured to fall smoothly into the feeding trough, thus ensuring smooth feeding.

[0028] Beneficial technical effects: The bar feeding equipment of this application can smoothly feed and transport small-diameter, easily bent bars. During the conveying process, the flip-top mechanism restricts the bar from bending violently, ensuring smooth conveying. At the same time, the bar is clamped from both the top and bottom, ensuring that the feed rod push plug can be smoothly inserted and fixedly connected to the bar. Finally, an electromagnetic clutch is used instead of an encoder to improve the synchronization accuracy of the synchronization mechanism, meeting the requirements of high processing accuracy for small bars.

[0051] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0052] The following is in conjunction with the appendix Figures 1-21 This application will be described in further detail.

[0053] In one aspect of the present disclosure, a bar feeding device is provided, the bar feeding device including a feeding device 1, a conveying device 4, a first transfer mechanism 7, a second transfer mechanism 6, a synchronization mechanism 8, and a positioning detection mechanism 9.

[0054] The feeding device 1 is used to supply the bar stock 2 one by one to the conveying device 4. Specifically, after the feeding device 1 feeds a bar stock 2 into the conveying device 4, the conveying device 4 feeds the bar stock 2 into the machine tool, where the machine tool processes the bar stock 2. After the bar stock 2 is processed, the feeding device 1 feeds another bar stock 2 into the conveying device 4, and the conveying device 4 feeds the bar stock 2 into the machine tool for processing. This is how the feeding device 1 supplies the bar stock 2 one by one to the conveying device 4.

[0055] During the process of conveying bar 2, the conveying device 4 needs to connect the bar 2 with a conveying component so that the bar 2 can move forward or backward. The transfer mechanism 7 is used to connect or separate the conveying component from the conveying device 4 to avoid the conveying component blocking the feeding device 1 from feeding the bar 2 into the conveying device 4. Therefore, when the feeding device 1 needs to feed the bar 2 into the conveying device 4, the conveying component is first separated from the conveying device 4. After the bar 2 is fed into the conveying device 4 and reaches the set position, the conveying component is connected to the conveying device 4. Then the conveying component can be connected to the bar 2.

[0056] During the process of conveying bar 2 by the feeding device 4, the cover plate 62 is needed to prevent the bar 2 from leaving the feeding device 4, so as to ensure that the bar 2 is smoothly conveyed to the machine tool for processing. At the same time, the cover plate 62 also needs to leave the feeding device 4 in a timely manner to avoid obstructing the feeding device 1 from feeding the bar 2 into the feeding device 4. The transfer mechanism 6 is used to drive the cover plate 62 to contact or separate from the feeding device 4. When the cover plate 62 contacts the feeding device 4, it can prevent the bar 2 from leaving the feeding device 4. When the cover plate 62 separates from the feeding device 4, it does not affect the feeding device 1 from feeding the bar 2 into the feeding device 4.

[0057] The synchronization mechanism 8 is used to link the feeding device 4 and the machine tool together to achieve synchronous operation of the two, so as to ensure that the bar 2 is processed smoothly.

[0058] The arrival detection mechanism 9 is used to detect the length of the bar 2 fed into the machine tool by the feeding device 4, so as to control the feeding device 4 to stop feeding in time when the length of the bar 2 fed into the machine tool reaches the set value.

[0059] The following is a detailed description of each component of the bar feeding equipment.

[0060] In the embodiments disclosed herein, such as Figures 1-7As shown, the feeding device 1 has multiple sets of conveyor plate groups arranged at intervals. The specific number of conveyor plate groups can be determined according to the length of the bar 2. Each set of conveyor plate groups includes a fixed plate 103 and a movable plate 107 arranged at intervals. The interval arrangement should be understood as the presence of a gap between the fixed plate 103 and the movable plate 107, and the gap value is not less than 0.

[0061] like Figure 4 , Figure 5 , Figure 7 As shown, the upper surfaces of both the fixed plate 103 and the movable plate 107 are provided with a plurality of toothed grooves 104 arranged at intervals along the conveying direction of the bar 2. Figure 4 The direction of the middle arrow indicates the direction in which the feeding device 1 conveys the bar 2. The fixed plate 103 is fixedly installed, and the movable plate 107 is rotatably mounted with multiple eccentric wheels 106. The eccentric wheels 106 are mounted on a rotating shaft 105, which is connected to a driving element 111. The eccentric wheels 106 are configured such that the driving element 111 drives the rotating shaft 105 to rotate, thereby causing the eccentric wheels 106 to rotate. The eccentric wheels 106 then cause the movable plate 107 to perform a circular translation relative to the fixed plate 103 on the vertical plane containing the side of the movable plate 107. When the movable plate 107 reaches its highest position, the lowest point of the tooth groove 104 of the movable plate 107 is above the highest point of the tooth groove 104 of the fixed plate 103. Conversely, when the movable plate 107 reaches its lowest position, the highest point of the tooth groove 104 of the movable plate 107 is below the lowest point of the tooth groove 104 of the fixed plate 103. This design utilizes the movement of the movable plate 107 relative to the fixed plate 103 to achieve the rotation of the rod 2 along... Figure 4 Move in the direction of the middle arrow.

[0062] Specifically, the placement of the bar 2 in the toothed groove 104 is as follows: Figure 4 As shown, when the movable plate 107 moves obliquely upward along the arc, it causes the rod 2 in the toothed groove 104 of the fixed plate 103 to rise and separate from the fixed plate 103. After the movable plate 107 rises to its highest point, it moves obliquely downward along the arc, causing the rod 2 to fall into another toothed groove 104 of the fixed plate 103. This other toothed groove 104 is adjacent to the aforementioned toothed groove 104 of the fixed plate 103. In this way, the rod 2 can be moved along the arc. Figure 4 Move in the direction of the middle arrow.

[0063] In one example, the feeding device 1 further includes a storage container 101 and a guide component 102, such as Figure 2 As shown, the storage container 101 is positioned higher than the conveyor plate assembly. The storage container 101 is used to temporarily store a large number of bars 2, such as... Figure 2 , Figure 4 , Figure 5 , Figure 7As shown, the upper surface of the guide component 102 is inclined. The high end of the upper surface of the guide component 102 is configured to receive the rod 2 falling from the storage container 101. The low end of the upper surface of the guide component 102 is configured to allow the rod 2, which slides obliquely downward along the upper surface of the guide component 102, to slide away from the low end and fall into the toothed grooves 104 corresponding to the multiple sets of conveyor plates.

[0064] Because the small-diameter rods 2 are soft, have poor rigidity, and are easily bent, it is very difficult to place the rods 2 directly into the corresponding slots 104 of multiple sets of conveyor plates by hand. It would take a lot of time to fill all the slots 104 with the rods 2, and it is difficult to ensure that each rod 2 corresponds to its own slot 104 one by one. This is especially true when the rods 2 are very long. It is very easy for other parts of the rods 2 to twist and leave the slots 104 of other conveyor plates or enter other slots 104 of other conveyor plates when the rods 2 are placed into the slots 104 of one set of conveyor plates. This brings great difficulties and troubles to the rod feeding work. Therefore, this embodiment includes a storage container 101 and a guide component 102. The bars 2 to be fed are stored in the storage container 101. When feeding into the toothed grooves 104, the bars 2 are manually or mechanically moved one by one from the storage container 101. Then, the bars 2 are precisely guided by the guide component 102 into the corresponding toothed grooves 104 on multiple sets of spaced-apart conveyor plates. This solves the problem of manually placing the bars 2 directly onto the multiple sets of spaced-apart conveyor plates. The guide component 102 ensures that the bars 2 accurately fall into the designated toothed grooves 104. Then, controlling the movable plate 107 to move relative to the fixed plate 103 drives the bars 2 along... Figure 4 Advance towards the conveying device 4 in the direction indicated by the middle arrow. After the bar 2 has advanced to the next adjacent toothed groove 104, continue to let the bar 2 fall into the guide component 102 and enter the designated toothed groove 104. In this way, the toothed grooves 104 on the conveying plate group can be easily and quickly filled with bar 2.

[0065] Furthermore, the movable plate 107 can also achieve circular translation of the rod 2 along the fixed plate 103. Figure 4The feed plate moves backward in the direction indicated by the middle arrow, closer to the guide component 102, to facilitate filling the grooves 104 on the feed plate assembly with bar 2, thus achieving continuous feeding of bar 2. For example, after all the bar 2 on the storage container 101 is laid on the grooves 104, the worker leaves the feeding device 1 to retrieve the next batch of bar 2, or temporarily leaves the work station for other matters. At this time, the feed device 4 is still working normally, and the feeding device 1 needs to supply one bar 2 to the feed device 4 every once in a while. Therefore, after a period of time, some grooves 104 on the feed plate assembly (grooves 104 near the guide component 102) will be empty of bar 2. Therefore, in order to ensure that the feeding device 1 always supplies bar 2 evenly and continuously to the feed device 4, it is necessary to control the movable plate 107 to drive the bar 2 along the feed plate assembly at an appropriate time. Figure 4 The bar 2 is moved back in the direction indicated by the middle arrow to the guide member 102, and then continues to fall into the guide member 102 into the designated toothed groove 104, thereby filling the toothed groove 104 on the feed plate assembly with the bar 2 again.

[0066] In the embodiments disclosed herein, such as Figure 4 As shown, a sensing element 110 is installed at the end of the rotating shaft 105, and a positioning detection device 108 is provided next to the sensing element 110. When the rotating shaft 105 drives the sensing element 110 to rotate one revolution, the positioning detection device 108 senses and generates a detection signal, and then controls the rotating shaft 105 to automatically stop rotating after each revolution, so that the bar 2 can enter the designated tooth groove 104 along the guide member 102.

[0067] In one example, such as Figure 4 As shown, the upper surface of the fixed plate 103 and the movable plate 107 has a feeding slope 109 at the feeding end. The bar 2 leaving the tooth groove 104 slides down the feeding slope 109 and falls into the feeding device 4 to feed the feeding device 4.

[0068] Optional, such as Figure 4 As shown, a guide frame 3 is provided between the feeding device 1 and the conveying device 4. The bar 2 that slides down from the unloading slope 109 continues to slide down along the guide frame 3 into the conveying device 4. The addition of the guide frame 3 can ensure that the bar 2 falls smoothly into the conveying device 4, thus ensuring that the feeding of the bar 2 in the conveying device 4 proceeds smoothly.

[0069] In the embodiments disclosed herein, such as Figures 1-21 As shown, the material conveying device 4 includes a slide rail 404, a slider 402, a drive mechanism, and a clamping mechanism 420. Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 16 , Figure 19As shown, the slide rail 404 is sequentially constructed with a first conveying trough 406, a dropping hole 418, and a second conveying trough 416 along the conveying direction of the bar 2. The bar 2 fed by the feeding device 1 falls into the first conveying trough 406. The transfer mechanism 7 drives the conveying component to connect with the conveying device 4, which means that the conveying component is placed into the first conveying trough 406. Under the drive of the conveying device 4, the bar 2 passes through the dropping hole 418 and enters the second conveying trough 416, and finally leaves the second conveying trough 416 and enters the machine tool. The first conveying trough 406, the dropping hole 418, and the second conveying trough 416 are arranged in a straight line along the length direction and conveying direction of the bar 2. After a bar 2 is processed by the machine tool, the remaining part is called the tail material 21. The tail material 21 is driven by the conveying device 4 to the dropping hole 418, and then the tail material 21 is released, falling through the dropping hole 418 and into the machine tool. Figure 1 The receiving box 5 shown below the discharge hole 418 is used to collect the tail material 21 of the bar stock 2, which is convenient for recycling.

[0070] like Figure 2 , Figure 4 , Figure 5 , Figure 7 As shown, the feeding trough 406 is located below the feeding end of the feeding plate group, and the bar 2 sliding down from the feeding end of the feeding plate group falls into the feeding trough 406.

[0071] In this embodiment of the disclosure, the slider 402 is connected to a driving mechanism, which drives the slider 402 to move on the slide rail 404, thereby moving the bar 2.

[0072] In one example, such as Figure 4 As shown, the slider 402 is provided with a roller 407, which is rotatably connected to the slide rail 404. The roller 407 can reduce the sliding wear and frictional resistance of the slider 402, which is conducive to the high-speed movement of the slider 402.

[0073] Optional, such as Figure 4 , Figure 10 , Figure 13 As shown, the driving mechanism is a belt conveyor, which includes a transmission belt 403, a transmission wheel 82, and a driving element 401. The transmission belt 403 is sleeved on the transmission wheel 82. The slider 402 is connected to the transmission belt 403. The driving element 401 is used to drive the transmission belt 403 to move, thereby driving the slider 402 to move on the slide rail 404.

[0074] In this embodiment of the present disclosure, the transfer mechanism 7 is connected to a material conveying component. The transfer mechanism 7 is configured to drive the material conveying component into the material conveying trough 406 and connect it to the slider 402, and to drive the material conveying component away from the material conveying trough 406 and separate it from the slider 402.

[0075] In one example, such as Figure 2 and Figure 4 As shown, the conveying component includes a conveying rod 411, a connecting plate 409, and a connecting block 410 fixedly connected to the conveying rod 411 and the connecting plate 409, as follows: Figure 2 As shown, the slider 402 is provided with an upwardly protruding limiting component 408, such as... Figure 5 , Figure 16 As shown, the end of the conveying rod 411 away from the connecting block 410 is provided with a plug 419. When the transfer mechanism 7 drives the conveying rod 411 into the conveying trough 406, the connecting plate 409 and the limiting component 408 are detachably plugged in and connected. When the transfer mechanism 7 drives the conveying rod 411 away from the conveying trough 406, the connecting plate 409 and the limiting component 408 are separated. This design facilitates the quick connection or separation of the conveying component and the slider 402, thereby smoothly completing the conveying operation of the bar 2.

[0076] Specifically, in one example, such as Figures 1-7 , Figures 11-15 , Figures 20-21 As shown, the transfer mechanism 7 includes a rotating shaft 65, a limiting block 73, and a push-pull component 66. Several hook rods 71 ​​and connecting components 72 are axially mounted on the rotating shaft 65. Figure 15 As shown, the hook rod 71 hooks onto the conveyor rod 411; as Figure 2 , Figure 13 , Figure 21 As shown, the limiting block 73 is fixedly connected to the connecting piece 72. The limiting block 73 is provided with a sliding groove 74, and the connecting plate 409 is provided with a sliding block 405. The sliding block 405 is slidably connected to the sliding groove 74, and the sliding direction is the conveying direction of the bar 2. Figure 12 As shown, the push-pull component 66 is connected to the rotating shaft 65 via the connecting rod 67, which drives the rotating shaft 65 to rotate, thereby causing the hook rod 71 and the limiting block 73 to rotate around the rotating shaft 65. In this way, the hook rod 71 drives the conveying rod 411, and at the same time, the limiting block 73 drives the connecting plate 409 to rotate around the rotating shaft 65, causing the conveying rod 411 to fall into the conveying trough 406 and the connecting plate 409 to descend and connect with the limiting component 408, thus fixing the connecting plate 409 and the slider 402 together. Subsequently, the slider 402 drives the connecting plate 409 and the conveying rod 411 to move back and forth along the conveying trough 406, causing the slider 405 to separate from the chute 74 and reconnect. Of course, the rotation of the rotating shaft 65 can also drive the conveying rod 411 to move upward away from the conveying trough 406 and the connecting plate 409 to move upward away from the limiting component 408 and separate from the slider 402.

[0077] In the embodiments disclosed herein, such as Figure 5 , Figure 7 , Figure 16As shown, the clamping mechanism 420 is located next to the discharge hole 418 and is used to clamp the bar 2 at the discharge hole 418 to facilitate the connection and separation of the conveying component and the bar 2.

[0078] It should be noted that the specific structure of the clamping mechanism 420 has been disclosed in CN119976355A, and will not be elaborated upon here.

[0079] In this embodiment, the clamping mechanism 420 moves and clamps the bar 2 from both the top and bottom directions, thus achieving coaxiality between the tail end of the bar 2 and the plug 419, ensuring that the feed rod 411 pushes the plug 419 to smoothly insert and fix it to the bar 2.

[0080] In this embodiment of the disclosure, the feeding device 4 also has a connection and separation mechanism, which is used to cooperate with the clamping mechanism 420 to complete the connection and separation of the feeding component and the bar 2.

[0081] Specifically, in one example, such as Figure 9 and Figure 13 As shown, the connecting and separating mechanism includes a second push-pull component 414, a second connecting rod 413, and a second lifting component 415. The pushing and pulling direction of the second push-pull component 414 is parallel to the length direction of the first conveying trough 406. One end of the second connecting rod 413 is hinged to the movable end of the second push-pull component 414, and the other end of the second connecting rod 413 is fixedly connected to a connector 412, such as... Figure 2 As shown, the upper end of the connector 412 is vertically and detachably connected to the connecting plate 409; as Figure 9 and Figure 13 As shown, the movable end of the lifting component 2 415 is connected to the slider 3 417, which is slidably connected to the connector 412. The sliding direction is the same as the pushing and pulling direction of the push-pull component 2 414. With this design, when the lifting component 2 415 moves the connector 412 upward, the connector 412 is connected to the connecting plate 409. At this time, the push-pull component 2 414 drives the conveying component to slide in the conveying trough 1 406 with the help of the connecting rod 2 413. This, together with the clamping mechanism 420, completes the connection and separation of the conveying component and the bar 2. When the lifting component 2 415 moves the connector 412 downward and separates it from the connecting plate 409, the slider 1 402 can drive the conveying component to slide in the conveying trough 1 406 to move the bar 2.

[0082] When the feeding device 1 feeds the bar 2 into the feeding trough 406, the control push-pull component 66 drives the rotating shaft 65 to rotate, which in turn drives the feeding component to move upward away from the feeding trough 406. After the bar 2 is fed into the feeding trough 406, the control drive mechanism drives the slider 402 to move along the feeding trough 406, so that the slider 402 pushes the bar 2 away from the feeding trough 406 and into the feeding trough 416. However, the end of the bar 2 is located at the discharge hole 418 so that the clamping mechanism 420 can clamp the tail end of the bar 2. After the slider 402 pushes the bar 2 away from the feeding trough 406 and into the feeding trough 416, the slider 402 returns to its original position. Figure 2 At the indicated position, the push-pull component 66 then drives the rotating shaft 65 to rotate, which in turn drives the conveyor component to move down into the conveyor trough 406 and connect with the slider 402. Then, the lifting component 415 drives the plug-in component 412 to move up so that the plug-in component 412 is plugged into the connecting plate 409. Next, the push-pull component 414 drives the conveyor component to slide in the conveyor trough 406 with the help of the connecting rod 413, so that the plug 419 is plugged into and fixedly connected to the tail end of the bar 2. Then, the lifting component 415 drives the plug-in component 412 to descend and separate from the connecting plate 409. In this way, the slider 402 can drive the bar 2 to move forward and backward in the conveyor trough through the conveyor component, and cooperate with the machine tool to complete the processing of the bar 2.

[0083] In this embodiment, the transfer mechanism 7 drives the limiting block 73 to rotate around the rotating shaft 65 via the connecting member 72. With the help of the limiting block 73, the connecting plate 409 moves synchronously with the hook rod 71 to achieve smooth lifting and lowering of the conveying component. The setting of the slider 405 and the slide groove 74 does not affect the slider 402 driving the connecting plate 409 to slide along the conveying groove 406 to separate from the limiting block 73, nor does it drive the connecting plate 409 to reconnect with the limiting block 73.

[0084] In this embodiment, the second transfer mechanism 6 is connected to a cover plate 62. The second transfer mechanism 6 is configured to drive the cover plate 62 in and out of the second feeding trough 416, that is, to drive the cover plate 62 to contact or separate from the feeding device 4. With this design, the feeding device 1 supplies the feeding device 4 with small-diameter, easily bendable rods 2. The feeding device 1 can realize the stable and orderly conveying of small rods 2, and can drive the small rods 2 forward or backward to meet the requirements of long-term continuous feeding. The cover plate 62 is set to prevent the rods 2 from bending and leaving the second feeding trough 416 during the conveying process, ensuring the smooth operation of the conveying work.

[0085] Specifically, in one example, such as Figure 7 , Figure 12 , Figure 17 As shown, the transfer mechanism 2 6 includes a connector 64 and a lifting component 63, as... Figure 12As shown, the first connector 64 is fixedly connected to the second rotating shaft 65, and the first connector 64 is fixedly connected to the mounting plate 61. The rotation of the second rotating shaft 65 drives the mounting plate 61 to rotate around the second rotating shaft 65. The first lifting component 63 is fixedly connected to the mounting plate 61. The cover plate 62 is connected to the movable end of the first lifting component 63. There are multiple cover plates 62, which are arranged in a straight line along the length of the second conveying trough 416. With this design, when the feeding device 1 needs to feed the bar 2 into the conveying trough 406, if the bar 2 is long, the cover plate 62 may obstruct the bar 2 from falling into the conveying trough 406. In this case, the push-pull component 66 can drive the rotating shaft 65 to rotate, which in turn drives the mounting plate 61 and the cover plate 62 away from the conveying trough 406, ensuring that the bar 2 falls smoothly into the conveying trough 406. Then, the rotating shaft 65 is controlled to reset the mounting plate 61, and the lifting component 63 is controlled to lower the cover plate 62 to block the conveying trough 416. This prevents the bar 2 from bending and leaving the conveying trough 416 during the conveying process, ensuring smooth material conveying. When the slider 402 and the connecting plate 409 need to move in the conveying trough 416, the lifting component 63 is controlled to raise the corresponding cover plate 62 to provide a space channel for the slider 402 and the connecting plate 409 to slide, preventing the cover plate 62 from blocking the slider 402 and the connecting plate 409 from sliding and pushing the bar 2 in the conveying trough 416.

[0086] After a bar 2 is processed, the tail 21 of the bar 2 is driven back to the dropping hole 418 by the conveying component. Then, the clamping mechanism 420 clamps the bar 2, and the connecting separation mechanism drives the conveying component to slide in the conveying trough 406 to separate the plug 419 from the tail 21 of the bar 2. Then, the clamping of the tail 21 is released, and the tail 21 falls through the dropping hole 418 into the receiving box 5. After that, the control transfer mechanism 7 drives the conveying component to leave the conveying trough 406, and the feeding device 1 feeds the next bar 2 into the conveying trough 406.

[0087] In one example, such as Figure 10 , Figure 17 , Figure 19 As shown, the synchronization mechanism 8 includes a drive shaft 81, a second drive wheel 83, an electromagnetic clutch 84, a third drive wheel 86, and a slide rod 88, as follows: Figure 10 As shown, the first transmission wheel 82 is mounted on the transmission shaft 81; the second transmission wheel 83 and the electromagnetic clutch 84 are mounted on the transmission shaft 81. The electromagnetic clutch 84 is configured to control the transmission wheel 83 and the transmission shaft 81 to be connected or disconnected. When the second transmission wheel 83 and the transmission shaft 81 are connected, the second transmission wheel 83 drives the first transmission wheel 82 to rotate synchronously. When the transmission wheel 83 and the transmission shaft 81 are disconnected, the second transmission wheel 83 rotates freely. Figure 17As shown, the third transmission wheel 86 is spaced apart from the second transmission wheel 83 along the conveying direction of the bar 2. A second transmission belt 85 is fitted onto both the second transmission wheel 83 and the third transmission wheel 86. Figure 17 and Figure 19 As shown, the slide bar 88 is arranged parallel to the conveying direction of the bar 2 and is fixedly connected to the transmission belt 85 via the mounting block 87. When the transmission belt 85 moves, it drives the slide bar 88 to move synchronously. The end of the slide bar 88 away from the transmission belt 85 is connected to the machine tool spindle. Thus, during the machining of the bar 2, the spindle moves, causing the slide bar 88 to move synchronously, which in turn drives the transmission belt 85 to move. The drive mechanism moves synchronously via the transmission shaft 81, achieving synchronous movement of the machine tool spindle and the bar 2, ensuring smooth machining of the bar 2. The electromagnetic clutch 84 is used instead of the encoder to improve the synchronization accuracy of the synchronization mechanism 8, meeting the high machining accuracy requirements of the small bar 2.

[0088] In one example, such as Figure 19 As shown, the positioning detection mechanism 9 includes a lifting component 91, a baffle 92, and a separation sensor 94. The movable end of the lifting component 91 is connected to a mounting component 93. The baffle 92 is located on the discharge path of the material conveying trough 416 and is hinged to the mounting component 93. The separation sensor 94 contacts the baffle 92 and is adapted to separate from the baffle 92 to generate a sensing signal. After the bar 2 moves away from the second conveying trough 416 under the drive of the conveying device 4, the head of the bar 2 hits the lower end of the baffle 92, causing the baffle 92 to rotate. Then, the upper end of the baffle 92 separates from the separation sensing device 94. At this time, the separation sensing device 94 generates a sensing signal. Based on the signal, the lifting component 91 is controlled to drive the baffle 92 to rise and leave the discharge path of the second conveying trough 416, so as to avoid affecting the discharge of the bar 2. At the same time, the timer starts according to the generated sensing signal to calculate the length of the bar 2 that leaves the second conveying trough 416 and enters the machine tool, so as to control the conveying device 4 to stop conveying in time when the length of the bar 2 fed into the machine tool reaches the set value.

[0089] Compared to photoelectric sensing detection methods, the mechanical positioning detection mechanism 9 in this embodiment not only has high detection accuracy and can detect small diameter rods 2, but also has low cost, long service life, and stable and reliable performance. In contrast, traditional photoelectric sensing detection methods either cannot accurately detect small diameter rods 2, or are expensive, lack reliability and stability, and are prone to failure and damage.
