Description

Technical Field

[0001] This utility model belongs to the technical field of workpiece annealing equipment, and particularly relates to a local annealing machine. Background Technology

[0002] Aerospace blind rivets are critical connecting components in the assembly of aircraft wings and fuselages, and their reliability depends on the quality of the localized annealing of the rivet sleeve (workpiece). The annealing process requires controlling the heating temperature error of the softening zone within ±10℃ and achieving extremely high uniformity to ensure a consistent hardness distribution around the rivet body. This uniformity of hardness is fundamental to achieving stable riveting force and rivet interchangeability, and directly relates to the integrity of the aircraft structure and flight safety.

[0003] After annealing, the workpiece sleeve needs to be ejected from the annealing machine via a blanking assembly. Currently, traditional blanking assemblies have design shortcomings; their structures are either too complex or too simple, making it difficult to achieve a good balance between manufacturing cost, operational efficiency, and feeding accuracy. More importantly, existing assemblies have poor adaptability to fluctuations in operating conditions, and their feeding process lacks necessary robustness, failing to ensure that the workpiece can stably and reliably enter the blanking assembly under various circumstances. This directly affects the automation level of the production line and the product qualification rate. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model discloses a partial annealing machine that can achieve a variety of highly adaptable feeding methods. It can not only reduce manufacturing and maintenance costs, but also more flexibly cope with different working conditions, ensuring that workpieces can be efficiently and reliably transferred out of the annealing machine under various circumstances.

[0005] The specific technical solution of this utility model is as follows: A partial annealing machine includes a feeding assembly, a transfer assembly, a clamping assembly, a heating assembly, and a unloading assembly. The transfer assembly transfers a workpiece from the feeding assembly to the clamping assembly. The heating assembly heats the workpiece placed on the clamping assembly. The unloading assembly receives the workpiece that falls from the clamping assembly. The clamping assembly includes a first top member and a second top member that can move relative to each other to clamp or release the workpiece. The first top member and / or the second top member can rotate about their own axis. The clamping assembly also includes a drive mechanism three and an air blowing block, which are connected in a transmission manner to drive the air blowing block to move toward or away from the workpiece. The air outlet of the air blowing block corresponds to the workpiece on the clamping assembly.

[0006] The first and second top members can clamp the workpiece. The function of the air blowing block is realized after the annealing process. Therefore, in order for the air blowing block to meet the unloading requirements well, its air outlet needs to be aligned with the workpiece on the clamping assembly. Thus, when unloading is required, the workpiece can be blown by the airflow. In some cases, the airflow cannot blow the workpiece away from the first and second top members well. At this time, the third drive mechanism can be activated to make the air blowing block knock the workpiece into the unloading assembly. It can be seen that the air blowing block in this application has multiple unloading methods and can be configured with different working conditions to ensure that the workpiece can be efficiently and reliably transferred out of the annealing machine under various conditions.

[0007] Preferably, the clamping assembly further includes a base one and a base two, at least one of which is movable relative to the other; The base is provided with a top member and a limiting member. The top member can rotate relative to the base about the axis of the top member. A buffer is provided between the limiting member and the top member. When the top member rotates about its own axis, the buffer is in a non-rotating state. A top member 2 is provided on the base 2, and the top member 2 can rotate relative to the base 2 about the axis of the top member 2; The clamping assembly further includes a drive mechanism for driving top member one and / or top member two to rotate about their own axis.

[0008] This application, by incorporating a buffer, effectively prevents workpiece damage due to overload during clamping. Simultaneously, the buffer's adaptive characteristics ensure stable clamping of the workpiece, reliably meeting clamping requirements. During the annealing process, the workpiece needs to continuously rotate around its own axis; therefore, both top members 1 and 2 must possess rotational capability. However, with a buffer, if one end rotates with top member 1 while the other end remains fixed, the force state of the buffer changes, failing to provide a continuous and uniform clamping force. Therefore, this application configures the buffer to remain in a non-rotating state when top member 1 rotates, thereby avoiding clamping force fluctuations caused by structural asynchrony and ensuring a stable clamping effect for the workpiece throughout its rotation.

[0009] Preferably, a rotating joint is provided at the end of the top member one that is away from the top member two, and the buffer member is disposed between the rotating joint and the limiting member. The rotating joint is used to bear the axial force and, when the top member one rotates around its own axis, allows relative rotation between the top member one and the buffer member.

[0010] Maintaining the non-rotating state of the buffer component while the top component rotates can be achieved through a rotating pair, avoiding axial misalignment caused by the rotational connection between the buffer component and the top component, thus preventing the inability to continuously provide uniform clamping force.

[0011] Preferably, the clamping assembly further includes: The slide rail, wherein base one and base two are slidably connected on the slide rail; and Drive mechanism two, the slide rail is set in the moving part of drive mechanism two to drive base one and base two to move synchronously.

[0012] Both base one and base two in this application can be adjusted to slide, which is beneficial to expanding the application conditions and thus better meeting the clamping requirements of the workpiece; the drive mechanism two can realize the synchronous position adjustment of base one and base two, thereby better meeting the position requirements of actual working conditions.

[0013] Preferably, the actuating part is provided with a base three; The top component 2 is provided with an airflow channel 1; The top part 2 is provided with a slip ring at the end away from the top part 1. The slip ring includes a fixed part and a rotating part. The rotating part is located inside the fixed part and is rotatably connected to the fixed part. The slip ring is connected to the airflow channel 1. The fixed part and the base are connected in three ways, and the rotating part and the top part are connected in two ways.

[0014] The slip ring can achieve negative pressure suction, thereby achieving the purpose of fixing the workpiece and heat dissipation. At the same time, it can also allow airflow, so that the corresponding holes can be cleaned when there is no workpiece. Since the slip ring includes a fixed part and a rotating part, it can also prevent air pipe entanglement.

[0015] Preferably, a metal heat sink is provided at one end of the top member two near the top member one; A heat dissipation sleeve is fitted on the outer side of the metal heat sink; The metal heat sink is provided with an airflow channel two, and the heat sink sleeve is provided with an airflow channel three. The airflow channel two is connected to the airflow channel one and the airflow channel three, and the airflow channel three is also connected to the outside.

[0016] During the annealing process, the metal heat sink can effectively meet the heat dissipation requirements, and the heat sink sleeve can improve the heat dissipation speed of the metal heat sink, thereby achieving a more effective heat dissipation effect.

[0017] Preferably, the drive mechanism three is disposed in the actuating part.

[0018] This structure enables the drive structure three to move the air blowing block in accordance with the motion of the action unit. After a single position adjustment, it can ensure that the air outlet of the air blowing block is always aligned with the position of the workpiece on the clamping assembly in subsequent processes, thereby meeting the subsequent unloading requirements.

[0019] Preferably, the feeding assembly includes a transfer mechanism and a distribution turntable. The distribution turntable has at least one interface on its circumference for receiving workpieces transferred by the transfer mechanism. The distribution turntable rotates to transfer the received workpieces to the discharge position of the feeding assembly.

[0020] The transfer mechanism can transfer the workpiece to the distribution turntable. By rotating the distribution turntable, the workpiece moves to the discharge position of the feeding component, so that the clamping component can further transfer the workpiece to the heating component for annealing. This structure is simple and has high transfer efficiency.

[0021] Preferably, the feeding assembly further includes a material guide, which is disposed on the path of the workpiece moving from the feeding position of the feeding assembly to the discharge position, and is used to adjust the posture of the workpiece.

[0022] When the workpiece moves to the loading position of the loading assembly, its axis may not be perpendicular to the rotation plane of the distribution turntable. This may cause the workpiece's axis to be inconsistent with the axes of top part one and top part two when the clamping assembly picks up the workpiece and places it on the heating assembly. Consequently, the workpiece cannot be heated evenly on its circumference when it rotates around its own axis, resulting in uneven heating. After setting the material pusher, the material pusher can keep the workpiece's axis perpendicular to the rotation plane of the distribution turntable during the drive movement of the distribution turntable, thereby ensuring the stability of subsequent processes.

[0023] Preferably, the transfer component includes: Clamping mechanisms are used to hold workpieces; and A motion mechanism that drives the gripping mechanism to rotate and / or move linearly.

[0024] The clamping mechanism can clamp the workpiece and transfer it to the heating assembly. Since the motion mechanism can realize the rotational and / or linear motion of the clamping mechanism, it can avoid motion interference between the clamping mechanism and other components while satisfying the workpiece transfer, thereby ensuring the stability of the annealing machine.

[0025] Preferably, the heating assembly includes a heating element with a central hole and a protective cover, as well as a drive mechanism for synchronously moving the heating element and the protective cover; The heating element is located on one side of the protective cover, and there is a gap between the heating element and the protective cover. The protective cover is provided with a vent for introducing protective gas. The top member one and top member two can reciprocate in the central hole.

[0026] An inert protective gas (usually argon) is introduced into the protective cover. This gas effectively prevents the workpiece from being oxidized during the annealing process by isolating it from oxygen, thus ensuring and effectively improving the yield of the workpiece.

[0027] Preferably, the feeding assembly includes: A guide box, wherein a guide channel one and a guide channel two are provided at the end of the guide box; and The material guide can switch between the first material dropping station and the second material dropping station to guide the material guide channel one or the second material guide channel.

[0028] After the annealing process is completed, the workpieces will be either good or defective. After the two are distinguished, they can be collected separately through different guide channels, thereby achieving the purpose of sorting good and defective products.

[0029] Preferably, the guide member has a drive mechanism five for driving its rotation, and the guide member rotates in a circular motion to guide either the first guide channel or the second guide channel; Alternatively, the guide member has a drive mechanism five for driving its linear motion, the guide member moving linearly in the arrangement direction of guide channel one or guide channel two to open guide channel one or guide channel two.

[0030] The material guide can be switched in various ways, and specific settings can be made according to actual conditions. All of the above structures have the advantages of stable operation and simple structure.

[0031] Preferably, when the guide component moves linearly in the arrangement direction of guide channel one or guide channel two, the guide component includes a dropping slope, and the workpiece falls onto the dropping slope to guide the workpiece into guide channel one or guide channel two.

[0032] The material drop slope can effectively guide the movement of the workpiece, allowing it to fall out of the annealing machine through a suitable material guide channel.

[0033] Preferably, the material feeding assembly further includes a temperature sensor, which is communicatively connected to the drive mechanism to connect either the material feeding channel one or the material feeding channel two.

[0034] The temperature sensor can sense the heating temperature of the workpiece and then determine whether the heating temperature in the circumferential direction of the workpiece is uniform, thereby realizing the judgment of good and bad products. The structure is simple and practical.

[0035] Compared with the prior art, this utility model achieves workpiece clamping through the combined action of top member one and top member two, thus completing the annealing process. After annealing, to meet the unloading requirements, the air outlet of the air blowing block is set to align with the workpiece on the clamping assembly. During unloading, the workpiece can be blown off by airflow. If the workpiece is not blown off smoothly for any reason, the drive mechanism three can be activated to push the air blowing block to mechanically knock the workpiece into the unloading assembly. Therefore, this application can flexibly adapt to different working conditions, ensuring that the workpiece can be efficiently and reliably transferred out of the annealing machine under various circumstances. The structure is simple and practical. In addition, this utility model can effectively solve the problem that the buffer is difficult to continuously apply stable clamping force during the workpiece's rotation around its own axis, thereby effectively avoiding pressure fluctuations caused by the workpiece's rotation. Based on providing stable clamping for the workpiece, this utility model ensures that the workpiece always maintains its position relative to the preset positioning reference surface during the annealing process, thereby guaranteeing the stability requirements of the annealing process and improving the heat treatment quality.

Detailed Implementation

[0038] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0039] like Figures 1 to 16As shown, a partial annealing machine includes a feeding assembly 200, a transfer assembly 300, a clamping assembly 400, a heating assembly 500, and a unloading assembly 600. The transfer assembly 300 transfers a workpiece 100 from the feeding assembly 200 to the clamping assembly 400. The heating assembly 500 heats the workpiece 100 placed on the clamping assembly 400. The unloading assembly 600 receives the workpiece 100 falling from the clamping assembly 400. The clamping assembly 400... The clamping assembly 400 includes a top member 3 and a top member 6 that are movable relative to each other to clamp or release the workpiece 100. The top member 3 and / or the top member 6 are rotatable about their own axes. The clamping assembly 400 also includes a drive mechanism 34 and an air blowing block 35. The drive mechanism 34 and the air blowing block 35 are tractively connected to drive the air blowing block 35 to move toward or away from the workpiece 100. The air outlet of the air blowing block 35 corresponds to the workpiece 100 on the clamping assembly 400.

[0040] In this embodiment, the air-blowing block 35 has two functional modes: a blowing mode, in which a high-pressure airflow blows the workpiece 100, which has been released from the top member 3 and the top member 2 6, into the unloading assembly 600; and a striking mode, in which the air-blowing block 35 mechanically strikes the workpiece 100 through the action of the drive mechanism 34, thereby knocking the workpiece 100 into the unloading assembly 600. This redundancy of the two modes ensures that the workpiece 100, having completed the annealing process, can fall into the unloading assembly 600, thus allowing the next workpiece 100 to be quickly placed between the top member 3 and the top member 2 6 and clamped, thereby improving process efficiency. In this embodiment, the drive mechanism 34 can be a cylinder, a gear and rack mechanism, a chain mechanism, etc. With the air-blowing block 35 positioned at the free end of the drive mechanism 34, it can reciprocate relative to the placement position of the workpiece 100 when the drive mechanism 34 is activated.

[0041] Furthermore, the clamping assembly 400 also includes a base 1 and a base 2, at least one of which is movable relative to the other; a top member 3 and a limiting member 4 are provided on the base 1, the top member 3 is rotatable relative to the base 1 about the axis of the top member 3; a buffer member 5 is provided between the limiting member 4 and the top member 3, the buffer member 5 is in a non-rotating state when the top member 3 rotates about its own axis; a top member 6 is provided on the base 2, the top member 6 is rotatable relative to the base 2 about the axis of the top member 6; the clamping assembly 400 also includes a driving mechanism 7 for driving the top member 3 and / or the top member 6 to rotate about their own axes.

[0042] In this embodiment, both the base 1 and the base 2 can reciprocate vertically. When they move closer to each other, they can clamp the workpiece 100. When they move further apart, the workpiece 100 can be removed from between the top piece 3 and the top piece 6. Of course, the workpiece 100 can also be placed there at this time.

[0043] like Figures 2-6 As shown, to better clamp the workpiece 100, one of the two opposite ends of the top member 3 and the top member 6 is provided with a positioning post 8, and the other is provided with a conical ejector pin 9. Specifically, in this embodiment, the top member 3 is provided with a conical ejector pin 9 to position the small-diameter end of the workpiece 100, and the top member 6 is provided with a positioning post 8 to position the large-diameter end of the workpiece 100. Generally speaking, the diameter of the positioning post 8 is similar to the diameter of the small-diameter end, thus better meeting the placement requirements of the workpiece 100.

[0044] In this embodiment, a metal heat sink 10 is provided at one end of the top member 2 6 near the top member 1 3; a heat sink sleeve 11 is fitted on the outer side of the metal heat sink 10. A mounting platform 2 12 is provided at the end of the top member 2 6, and the metal heat sink 10 is placed on the mounting platform 2 12. At this time, a positioning post 8 can be placed on the metal heat sink 10, thereby improving heat dissipation performance. The heat sink sleeve 11 further enhances the heat dissipation effect. The metal heat sink 10 is preferably a copper base, and the heat sink sleeve 11 can be made of aluminum alloy, ceramic, etc. Furthermore, the mounting platform 2 12 has a protruding structure, through which the metal heat sink 10 connects with the mounting platform 2 12. In addition, to meet heat dissipation requirements and structural optimization requirements, the positioning post 8 or a conical pin 9 is provided on the metal heat sink 10.

[0045] In this embodiment, the limiting member 4 is a cover structure, and the buffer member 5 is located inside the limiting member 4. Thus, by limiting one end of the buffer member 5 with the limiting member 4, the function of the buffer member 5 can be prevented from being affected by external dust and other impurities.

[0046] In some embodiments, one end of the buffer member 5 is fixedly connected to the limiting member 4, and the other end is movably connected to the top member 3. That is, when the top member 3 rotates, the buffer member 5 can remain in a non-rotating state. However, since the buffer member 5 itself has deformation capability, the rotation of the top member 3 may still cause the buffer member 5 to rotate. Therefore, the adaptive clamping force of the buffer member 5 on the workpiece 100 is unstable. Thus, in this embodiment, a rotating joint 13 is provided at the end of the top member 3 away from the top member 6. The buffer member 5 is disposed between the rotating joint 13 and the limiting member 4. The rotating joint 13 is used to bear the axial force and, when the top member 3 rotates around its own axis, allows relative rotation between the top member 3 and the buffer member 5. Specifically, the top member 3 has a mounting platform 14 at its end, and the rotating joint 13 is mounted on the mounting platform 14. The rotating joint 13 has a moving part and a stationary part. The moving part is connected to the mounting platform 14, and the stationary part has a positioning platform 15 with a positioning protrusion 16. Thus, the buffer member 5 is placed on the positioning platform 15 via the positioning protrusion 16. Furthermore, the mounting platform 14 has a groove structure, and the moving part of the rotating joint 13 is located in the groove structure. Therefore, when the top member 3 rotates around itself, the buffer member 5 can maintain a non-rotating state.

[0047] In this embodiment, the rotating pair 13 is configured as a thrust bearing, which can effectively bear axial forces and allow relative rotation between the top member 3 and the buffer member 5 when the top member 3 rotates around its own axis. In other embodiments of this embodiment, the rotating pair 13 can also be configured as a self-lubricating bearing, a tapered roller bearing, a thrust washer, etc.

[0048] It should be noted that in this embodiment, one end of the workpiece 100 contacts the top member 3 and the other end contacts the top member 6. Therefore, in order to ensure the smooth rotation of the workpiece 100, the optimal implementation is that the top member 3 and the top member 6 rotate synchronously. Thus, in order to improve the rotation performance of the top member 3 and the top member 6, a sleeve 17 is provided on the base 1. At least a part of the top member 3 is located inside the sleeve 17, and a bushing 18 is sleeved on the outer side of the top member 3. Furthermore, the bushing 18 is provided with balls. One end of the bushing 18 is received by the inner ring of the sleeve 17, and the other end of the bushing 18 is axially limited by the snap ring 19. This structure is simple and easy to assemble. In other embodiments, thrust needle roller bearings can also be used for axial limitation at both ends of the bushing 18. For the top part 3 or the top part 6, one of the thrust needle roller bearings can be limited by the mounting platform 14 or the mounting platform 22, and the other can be limited by the locking nut. The bushing 18 has a ball groove, and the balls are placed in the groove. Thus, the bushing 18 can realize the function of a bearing, which can ensure that it is aligned with the rotation axis of the top part 3 while facilitating installation, effectively improving the rotation efficiency of the top part 3. Similarly, for the top part 6, the base 2 is provided with a sleeve 20, at least a part of the top part 6 is located inside the sleeve 20, and the outer side of the top part 6 is fitted with a bushing 21; the bushing 21 is provided with balls.

[0049] like Figures 2-4 As shown, in this embodiment, the second top member 6 is a hollow shaft. Based on this, in this embodiment, a slip ring 22 is provided at the end of the second top member 6 away from the first top member 3. The slip ring 22 includes a fixed part and a rotating part. The rotating part is located inside the fixed part and is rotatably connected to the fixed part. The slip ring 22 communicates with the airflow channel 31. The fixed part is connected to the second base 2, and the rotating part is connected to the second top member 6. The slip ring 22 has a switching channel for positive and negative airflow. Of course, the switching between positive and negative airflow can also be achieved by connecting the slip ring 22 to different air pipes. During the annealing process, negative airflow can provide stability for the placement of the workpiece 100 and can remove some heat during heating. When the workpiece 100 is not clamped between the first top member 3 and the second top member 6, positive airflow can cool the placement position of the workpiece 100, providing a good annealing foundation for the next workpiece 100. In addition, positive airflow can also clear the airflow channel. Furthermore, as... Figure 9As shown, the metal heat sink 10 is provided with an airflow channel 2 32, and the heat sink sleeve 11 is provided with an airflow channel 33. The airflow channel 2 32 connects to the airflow channel 1 31 and the airflow channel 33, and the airflow channel 33 also connects to the outside. It should be noted that the negative pressure airflow enters the airflow channel 1 31 from the slip ring 22, and then acts on the metal heat sink 10 to stabilize the placement of the metal heat sink 10 while simultaneously drawing in outside air to dissipate heat from the heated area.

[0050] As can be seen from the above, the clamping assembly 400 in this embodiment realizes the start and stop of positive and negative airflow, which has a good usage effect. During the annealing process, the top part 3 and the top part 6 will rotate, and the air pipe connected to the top part 6 will also become entangled. Therefore, based on the setting of the slip ring 22, the air pipe can be effectively prevented from becoming entangled, thereby improving the usage safety of this embodiment.

[0051] In this embodiment, the drive mechanism 7 is configured as a synchronous belt mechanism, a gear mechanism, or a chain mechanism. For ease of installation and structural simplification, as a preferred embodiment, such as... Figures 1-3 As shown, the drive mechanism 7 is configured as a synchronous belt mechanism. The drive mechanism 7 is used to drive the top member 6 to rotate around its own axis. Furthermore, it also includes a slide rail 23, on which the base 1 and base 2 are slidably connected. Driven by a linear motion module, or by a cylinder mechanism, gear and rack mechanism, lead screw mechanism, etc., it can be achieved. Therefore, in this embodiment, base 1 and base 2 can reciprocate along a straight line relative to the other. In other embodiments, clamping or releasing the workpiece 100 can also be achieved by the relative rotation of base 1 and base 2. Furthermore, in this embodiment, it also includes a drive mechanism 24, with the slide rail 23 disposed in the actuating part 30 of the drive mechanism 24. Specifically, in addition to the slide rail 23, the actuating part 30 also has a base 25. The fixed end of the synchronous belt mechanism is set on the base, and the driving end of the synchronous belt mechanism is set with pulley one. Pulley two is set on the top part 2 6. The top part 2 6 is driven by the synchronous belt meshing with pulley one and pulley two. Based on this structure, the driving mechanism one 7 drives the top part 2 6 to rotate, and the driving force is transmitted to the workpiece 100, causing the workpiece 100 to rotate. Then, the workpiece 100 drives the top part one 3 to rotate. Since the workpiece 100 is clamped by the top part one 3 and the top part two 6, and the buffer 5 can provide adaptive clamping force, the requirement of the annealing process can be well met by using only the driving mechanism one 7 to drive the top part two 6 to rotate.

[0052] In this embodiment, the second drive mechanism 24 is a linear displacement mechanism. When the linear displacement mechanism operates, its moving part 30 can reciprocate vertically, thereby carrying the slide rail 23 and the base 25 in synchronous motion. It should be noted that the relative position between the base 25 and the moving part 30 is determined, and the second base 2 can move relative to the moving part 30. The relative position adjustment of the second base 2 is usually performed before the workpiece 100 is processed, with the aim of determining the optimal placement position of the workpiece 100. The optimal placement position can also be achieved through the second drive mechanism 24. In this way, one achieves a large-range adjustment and the other achieves a small-range adjustment. For example, the movement of the moving part 30 achieves a large-range adjustment (coarse adjustment) of the placement position of the workpiece 100, while the movement of the second base 2 achieves a small-range adjustment (fine adjustment). Thus, in the actual clamping and releasing of the workpiece 100, the displacement of the first base 1 is sufficient. Furthermore, in this embodiment, the adjustment of the base 1 can be achieved by a cylinder, and the adjustment of the base 2 can be achieved by a push screw. This not only facilitates the quick clamping and releasing of the workpiece 100, but also enables faster fine-tuning, and is more conducive to saving costs and reducing assembly volume. In other embodiments, the base 1 can also be implemented by a gear and rack mechanism, a linear module, etc. In the specific annealing process, the workpiece 100 is carried in the heating zone of the heating assembly 500 by the action of the drive mechanism 24 to realize the annealing process; of course, a three-axis slide can also be set in the heating assembly 500, which moves in three mutually perpendicular directions to meet its own positioning requirements and the heating requirements of the workpiece 100.

[0053] In this embodiment, to ensure high blowing efficiency of the air-blowing block 35, the drive mechanism 34 is located on the actuating part 30. Therefore, when the actuating part 30 moves under the drive of the drive mechanism 24, the workpiece 100 and the air-blowing block 35 move synchronously. That is, the placement position of the workpiece 100 and the air-blowing block 35 move synchronously. Specifically, when the top member 26 remains relatively stationary, and the top member 3 moves to release the workpiece 100, the air-blowing block 35 can disengage the workpiece 100 from the clamping assembly 400 in different ways. Furthermore, this structure only requires one of the air-blowing block 35 and the top member 26 to adjust its position relative to the other, making the adjustment structure simple and the process convenient.

[0054] like Figure 8As shown, in this embodiment, the base 1 includes a first part 26 and a second part 27. The first part 26 is slidably connected to the slide rail 23. The second part 27 is adjustablely disposed on the first part 26, and the limiting member 4 is adjustablely disposed on the second part 27. Specifically, the second part 27 can be slidably adjusted on the first part 26 by adjusting screw a28, and the limiting member 4 can be slidably adjusted on the second part 27 by adjusting screw b29. The movement direction of the first part 26, the adjustment direction of the second part 27, and the adjustment direction of the limiting member 4 are perpendicular to each other. Thus, with the axis of the second top part 6 as a reference, it is ensured that the axis of the first top part 3, the axis of the buffer part 5, and the axis of the second top part 6 are coaxial, thereby better ensuring the rotation requirements of the workpiece 100 in the annealing process.

[0055] like Figure 1 and Figure 10 As shown, in this embodiment, the feeding assembly 200 includes a transfer mechanism 36 and a material distribution turntable 37. The material distribution turntable 37 is provided with at least one interface portion 38 in its circumferential direction for receiving the workpiece 100 transferred by the transfer mechanism 36. The material distribution turntable 37 rotates to transfer the received workpiece 100 to the discharge position of the feeding assembly 200.

[0056] The transfer mechanism 36 consists of a vibratory feeder mechanism and a linear vibration mechanism. Through these two mechanisms, the workpiece 100 stored in the vibratory feeder mechanism can be transferred to the material distribution turntable 37. When the interface part 38 and the end of the linear vibration mechanism are connected, the workpiece 100 can enter the interface part 38. At this time, the material distribution turntable 37 rotates, which can transfer the workpiece 100 to the discharge position of the feeding component 200, so that the transfer component 300 can pick up the workpiece 100 to be annealed.

[0057] When the material distribution turntable 37 is provided with only one interface section 38, the movement of the material distribution turntable 37 is usually configured as reciprocating motion. However, when the material distribution turntable 37 is provided with multiple interface sections 38 on the circumference, the material distribution turntable 37 usually performs intermittent circular motion. This is beneficial to improving the material receiving efficiency of the feeding assembly 200. In other words, when the previous workpiece 100 reaches the discharge position, the next workpiece 100 can enter the next interface section 38.

[0058] It should be noted that the material distribution turntable 37 includes a disc body 39 and a guide body 40. The movement of the material distribution turntable 37 involves clamping the workpiece 100 between the disc body 39 and the guide body 40, and the rotation of the disc body 39 causing the workpiece 100 to move along the extension direction of the guide body 40. In other words, when the material distribution turntable 37 is in motion, the guide body 40 remains relatively stationary, and only the disc body 39 rotates. It is known that the interface portion 38 is located circumferentially on the disc body 39.

[0059] like Figure 11As shown, to better utilize this embodiment, the feeding assembly 200 further includes a material guide 41, which is disposed on the path of the workpiece 100 moving from the feeding position to the discharging position of the feeding assembly 200, and is used to adjust the posture of the workpiece 100. A gap 47 exists between the material guide 41 and the material distribution turntable 37. Specifically, the material guide 41 can be disposed on the guide body 40 and remain stationary. When the workpiece 100 rotates to the material guide 41, if the axis of the workpiece 100 and the turntable 39 are not at a 90° angle, the material guide 41 can contact the upper surface of the workpiece 100, thereby correcting the transport posture of the workpiece 100 so that the axis of the workpiece 100 and the turntable 39 are at a 90° angle, thus better meeting the uniformity requirements of the annealing process.

[0060] In this embodiment, both the loading and unloading positions of the material distribution turntable 37 are equipped with diffuse reflective optical fibers, which can determine whether the workpiece 100 is in place, thereby linking the subsequent transfer component 300.

[0061] like Figure 1 ,like Figure 12As shown, in this embodiment, the transfer assembly 300 includes a gripping mechanism 42 and a motion mechanism; the gripping mechanism 42 is used to grip the workpiece 100; the motion mechanism drives the gripping mechanism 42 to rotate and / or move linearly. The gripping mechanism 42 includes a first gripper and a second gripper that can move relative to each other, thereby achieving the gripping of the workpiece 100. The first gripper and the second gripper can move relatively linearly to grip the workpiece 100, or they can rotate relative to each other to meet the requirements of gripping the workpiece 100. In this embodiment, the first gripper and the second gripper can achieve relative movement by being driven by a cylinder to clamp the workpiece 100; the motion mechanism includes a first power mechanism 43 and a second power mechanism 44. The first power mechanism 43 can drive the clamping mechanism 42 to move, and the second power mechanism 44 can drive the second power mechanism 44 to move. Specifically, the first power mechanism 43 is a pneumatic swing table, the free end of which is connected to the clamping mechanism 42. The second power mechanism 44 is a lead screw mechanism, which includes a slider, a lead screw, and a slide rail 23. The first power mechanism 43 is mounted on the slider. The slider and the lead screw are connected by transmission and are slidably connected to the slide rail 23, so that when the lead screw rotates, the slider can achieve linear displacement, thereby achieving linear displacement of the clamping mechanism 42. In this embodiment, when the workpiece 100 is placed into the clamping assembly 400, the workpiece 100 is inverted, that is, the workpiece 100 is rotated 180° by the power mechanism 43. The advantage of this is that the workpiece 100 in this embodiment is usually configured as a nail sleeve. Therefore, during the initial transfer (at the loading assembly 200 and the transfer assembly 300) of the nail sleeve, the movement can be limited by the convex edge of the nail sleeve. That is, at this time the convex edge is on top, and the movement stability of the workpiece 100 is maintained by overlapping. When the workpiece 100 is placed into the clamping assembly 400, it can be placed and positioned by the convex edge with a large contact area between it and the top part 6. Therefore, the inversion of the workpiece 100 by the power mechanism 44 is beneficial to the transfer and annealing of the workpiece 100.

[0062] like Figure 1 ,like Figure 13 and Figure 14As shown, in this embodiment, the heating assembly 500 includes a heating element with a central hole and a protective cover 45, as well as a drive mechanism 46 for synchronously moving the heating element and the protective cover 45. The heating element is located on one side of the protective cover 45, and there is a gap 47 between the heating element and the protective cover 45. The protective cover 45 is provided with a vent 48 for introducing protective gas. The top member 3 and the top member 6 can reciprocate within the central hole. In this embodiment, the heating element includes a heating coil 49 and a heating head 50. The heating coil 49 can provide heating capability to the heating head 50, thereby achieving heating of the workpiece 100. It is known that both the heating coil 49 and the heating head 50 have a central hole so that the top member 3 and the top member 6 can reciprocate axially inside the heating element. In addition, the protective cover 45 is connected to the drive mechanism 46 through a cover bracket so that the heating element and the protective cover 45 move synchronously. The protective cover 45 is connected above the heating head 50. Argon gas is introduced through the air hole 48. The argon gas flows out from the gap 47 between the heating element and the protective cover 45, so that the space in the protective cover 45 is in an argon gas environment. The workpiece 100 is heated in this environment, thereby avoiding oxidation. It can be seen that the gap 47 is very small and does not affect the argon gas environment. Specifically, taking the movement of drive mechanism 24 as an example, in this embodiment, the protective cover 45 covers the heating head 50, forming a relatively sealed argon gas protective space between the protective cover 45 and the heating head 50. The nail sleeve (workpiece 100) moves with the clamping assembly 400. At this time, the top part 3 and the top part 6 clamp the workpiece 100 and extend it into the protective cover 45 through the central hole. Then, the top part 6 drives the nail sleeve to rotate, and the top part 3 also rotates along with it. Thus, the heating head 50 can uniformly heat the outside of the nail sleeve. Since argon gas is introduced into the protective cover 45 during heating, the nail sleeve is effectively protected, preventing it from being oxidized during the annealing process, thereby realizing the annealing process. It can be seen that the same principle can be achieved when drive mechanism 46 replaces drive mechanism 24 for the main annealing movement, which will not be elaborated here. The drive mechanism 46 is the three-axis slide table mentioned above.

[0063] like Figure 1 , Figure 15 and Figure 16As shown, in this embodiment, the unloading assembly 600 includes a guide box 51 and a guide component 52; the end of the guide box 51 is provided with a first guide channel 53 and a second guide channel 54; the guide component 52 switches between unloading station one and unloading station two to guide either the first guide channel 53 or the second guide channel 54. The inlet end of the guide box 51 is located on the side where the workpiece 100 is placed in the clamping assembly 400, and on the opposite side of the air blowing block 35, thus ensuring that the workpiece 100 can fall into the guide box 51 in different ways. When workpiece 100 is a good product, it falls out from guide channel 1 53; when workpiece 100 is a defective product, it falls out from guide channel 2 54. In this embodiment, the guide component 52 has a drive mechanism 55 for switching its position. The unloading assembly 600 also includes a temperature sensor 56, which is communicatively connected to the drive mechanism 55 to connect guide channel 1 53 or guide channel 2 54. Thus, after the annealing process is completed, the temperature sensor 56 can sense the circumferential temperature of workpiece 100 to determine whether it is uniform and meets the preset temperature requirements, thereby realizing the action of drive mechanism 55. The temperature sensor 56 is mounted on one side of the heating assembly 500 via a mounting bracket 57.

[0064] Furthermore, such as Figure 16 As shown, in some embodiments of this example, the guide member 52 has a drive mechanism 55 for driving its rotation. The guide member 52 rotates circumferentially to guide the first guide channel 53 or the second guide channel 54. The guide member 52 can be disposed between the first guide channel 53 and the second guide channel 54, and is flipped by the drive mechanism 55, thereby closing the first guide channel 53 or the second guide channel 54, thus allowing selection of the material dropping position. In this embodiment, as... Figure 15As shown, the guide member 52 has a drive mechanism 55 for driving its linear motion. The guide member 52 moves linearly in the arrangement direction of the first guide channel 53 or the second guide channel 54 to open the first guide channel 53 or the second guide channel 54. Taking the guide member 52 located on one side of the first guide channel 53 as the initial position, when the workpiece 100 is a good product, the guide member 52 remains closed, and the workpiece 100 can fall directly into the first guide channel 53. When the workpiece 100 is a defective product, the guide member 52 moves to the position of closing the first guide channel 53, and then the workpiece 100 can fall into the second unloading channel. That is to say, when the guide member 52 moves linearly in the arrangement direction of the first guide channel 53 or the second guide channel 54, the selection of the first guide channel 53 and the second guide channel 54 can be realized. Furthermore, the guide component 52 includes a drop slope 58, to which the workpiece 100 falls to guide the workpiece 100 into either guide channel one 53 or guide channel two 54. The drop slope 58 not only guides the workpiece 100 but also closes one of the guide channels, resulting in a simple and practical structure. Furthermore, in this embodiment, a triangular partition plate 59 is provided between guide channel one 53 and guide channel two 54, thereby better ensuring that the workpiece 100 falls out of guide channel one 53 when a good product falls.

[0065] This effectively enables the collection of both good and defective workpieces 100.

For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
