Description

Technical Field

[0001] This invention relates to the field of fuel injector testing technology, and in particular to a conveying device for detecting the protrusion height of fuel injectors. Background Technology

[0002] When inspecting the protrusion height of the S04 / F30 injector on the final assembly line in the workshop, the operation process is quite complicated. The operator needs to first stand up the cylinder head, add a copper washer to assemble the injector into place, and then use a dial indicator to check the protrusion height of the injector. After the inspection is completed, the injector needs to be removed from the cylinder head.

[0003] Currently, Chinese patent application number CN202410172545.4 discloses a single-cylinder diesel engine cylinder head processing production system and its working method. This invention's single-cylinder diesel engine cylinder head processing production system and its working method utilize a conveying device to transport the diesel engine cylinder head to be processed; the cylinder head is clamped by a push-pull mechanism; and a pressing device presses an injector copper sleeve into the clamped cylinder head, thereby achieving the installation of the injector copper sleeve. Furthermore, the pressing device, through a copper sleeve pressing rod, can perform quality inspection before pressing the injector copper sleeve to avoid the need for disassembly after installation of defective copper sleeves. Although it can transport the cylinder head... While the cylinder head is being transported, the fuel injectors are inspected. However, due to the different processing environments of the cylinder head during transportation, the smoothness of its bottom varies. That is, when the cylinder head has been polished, its bottom is smooth. If the same smooth roller is used for transportation, slippage and misalignment are likely to occur. Conversely, if the cylinder head has been painted, its surface is coated with anti-corrosion paint. If rollers with a higher coefficient of friction are used for transportation, this will wear down the anti-corrosion paint on the surface of the cylinder head, thus affecting the anti-corrosion effect.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were discovered:

[0005] The roughness of the conveyor belt cannot be freely adjusted as needed, and it is easy to cause wear to the cylinder head: When the existing cylinder head is inspected, the conveyor belt is stopped. This requires the motor used to control the conveyor belt to repeatedly start and stop. This not only easily damages the motor, but also prevents the cylinder heads on the same conveyor belt from moving, thus affecting subsequent processes. In addition, the cylinder head is heavy, and the motor is affected by inertia during the start and stop process, resulting in very large resistance during start and stop, which further affects the service life of the motor.

[0006] Therefore, the commonly used cylinder head transportation method relies on rollers as the power source. However, since the surface roughness of the rollers is constant and cannot be changed, while the cylinder needs to stop moving at the inspection station during inspection, clamping or other methods are required to limit the cylinder head. Furthermore, because the cylinder head is too large to be easily lifted, its bottom will still be in contact with the moving rollers, causing relative movement between the rollers and the conveyor belt. For cylinder heads with anti-corrosion paint, a large roller roughness will cause wear. Therefore, for cylinder heads that have been painted or surface-treated, smooth rollers are mostly used as transportation devices. Secondly, because the friction between smooth rollers and cylinder heads is small, rollers with large roughness are required for transportation of cylinder heads that have been ground and polished to avoid misalignment. However, existing cylinder head transportation devices do not have roughness adjustment functions, making it difficult to adapt to the various transportation needs of existing cylinder heads. Therefore, we propose a transportation device for detecting the protrusion height of fuel injectors. Summary of the Invention

[0007] (a) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this invention provides a conveying device for detecting the protrusion height of fuel injectors. By employing an interlocking method to connect the rollers and anti-slip sleeves, and by providing threads on the outer wall of the anti-slip sleeves to increase their surface roughness, the device's applicability is improved. This solves the technical problem of existing conveying devices for cylinder heads being unable to freely adjust the roughness of the conveyor belt as needed, and easily causing wear to the cylinder head.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A conveying device for detecting injector protrusion height, the conveying device comprising:

[0012] support;

[0013] A conveyor, mounted on a support, is used to convey the cylinder head;

[0014] The conveying component includes a roller and an anti-slip sleeve that are nested together, and the two have different surface roughnesses. The roller is driven to rotate by a motor.

[0015] When the anti-slip sleeve slides to one end of the roller near the center of the bracket, the anti-slip sleeve wraps around the outside of the roller, and the roller contacts the cylinder head through the anti-slip sleeve.

[0016] Preferably, a protective plate is provided at the top of the bracket and near the two side edges, and the protective plate is provided with a linkage inside to drive the anti-slip sleeve to slide.

[0017] The linkage includes a connecting plate disposed inside the protective plate, and the connecting plate is connected to the end of the anti-slip sleeve away from the roller through a bearing. Under the action of the driver, the connecting plate drives the anti-slip sleeve connected to it to move synchronously.

[0018] Preferably, the bracket has a groove at its top and near its edge, and the protective plate has a through hole at the position opposite to the groove. The roller is located in the groove, and when the anti-slip sleeve moves away from the roller, the anti-slip sleeve is located in the through hole on the surface of the protective plate.

[0019] Preferably, the actuator includes a knob disposed on the protective plate, with its head located on the outside of the protective plate, and its screw portion extending into the interior of the protective plate and connected to the inner wall of the protective plate. The end of the connecting plate is connected to the screw, and the connecting plate can be slid when the knob is rotated.

[0020] Preferably, the conveying component further includes a central shaft disposed on the top of the support, and the two ends of the central shaft extend into the protective plates on both sides of the support and are connected to the inner wall of the protective plates through bearings. The roller is connected to the central shaft near the end position, and the surface of the central shaft protrudes from the plane where the top of the support is located.

[0021] The anti-slip sleeve has an inner ring at one end opposite to the connecting plate, and the inner ring can slide along the groove on the outer wall of the central shaft. When the roller and the anti-slip sleeve are in contact, the mating pin on the inner wall of the anti-slip sleeve is inserted into the mating groove on the outer wall of the roller.

[0022] Preferably, the protective plate has a driven gear installed inside, and the driven gear corresponds to the end of the central shaft. The driven gear can be driven to rotate by a motor on the outside of the bracket, and then the driven gear transmits power to the central shaft.

[0023] Preferably, the outer side of the protective plate is provided with a switching component, and the switching component corresponds one-to-one with the conveying component inside the protective plate, so that the docking cylinder can be connected to the central shaft through the switching component;

[0024] The switching component includes corresponding electromagnetic rings and movable rings, which are connected by a return spring. The center of the movable ring is connected to a connecting pin by a bearing. When the electromagnetic ring is de-energized, the connecting pin is inserted between the driven gear and the central shaft under the action of the spring.

[0025] Preferably, the switching component further includes a protective cover connected to the protective plate, and both the electromagnetic ring and the movable ring are disposed inside the protective cover, with the electromagnetic ring disposed on the side of the movable ring away from the protective plate;

[0026] When the electromagnetic ring is energized, the movable ring drives the connecting pin to move in the direction of the electromagnetic ring, and the connecting pin moves out from the end of the central shaft.

[0027] Preferably, a docking cylinder is inserted at the center of the driven gear, and the docking cylinder is connected to the inner wall of the protective plate near the switching component via a bearing. Limiting strips are provided inside the docking cylinder, on the inner wall of the central shaft corresponding to the docking cylinder, and on the outer wall of the connecting pin. When the connecting pin and the docking cylinder are inserted, the limiting strips between them are interleaved.

[0028] Preferably, a retaining ring is provided at the opening of the protective cover, and the retaining ring and the movable ring face the side of the protective plate, and the movable ring is in contact with the outer wall of the retaining ring under the action of the return spring;

[0029] The inner wall of the protective cover is provided with a guide strip, and the notch on the edge of the movable ring corresponds to the guide strip. The movable ring can extend along the length of the guide strip.

[0030] (III) Beneficial Effects

[0031] 1. By using an interlocking method to connect the rollers and anti-slip sleeves, and by setting threads on the outer wall of the anti-slip sleeves to increase their surface roughness, the device improves its applicability by allowing control over whether the anti-slip sleeves are fitted over the rollers as needed. Furthermore, by connecting the anti-slip sleeves to a connecting plate and then to a knob on the protective plate, rotating the knob drives the anti-slip sleeves connected to the connecting plate to move synchronously. Therefore, this effectively solves the technical problem of existing conveyor devices for cylinder heads under inspection, which cannot freely adjust the roughness of the conveyor belt as needed and easily cause wear to the cylinder head. This achieves the goal of freely adjusting the surface roughness of the conveyor device, allowing adjustment based on the processing conditions of the cylinder head or the workpiece being transported, thus adapting to various processing requirements and improving the device's applicability.

[0032] 2. By setting a switching component on the outside of the protective plate and corresponding it to the roller on the bracket, electromagnetic induction technology is used to attract the iron (or magnet, etc.) movable ring when the electromagnetic ring is energized. This causes the connecting pin inserted between the central shaft and the docking cylinder to retract back into the docking cylinder. At this time, the driven gear driven by the motor cannot transmit torque through the connecting pin, so the roller at this position is stationary, and the cylinder head on it can be inspected by the testing equipment. Conversely, when the electromagnetic ring is de-energized, the connecting pin is inserted into the hole at the end of the central shaft under the push of the return spring. Limiting strips are set on the hole and the outer wall of the connecting pin to ensure that the torque of the driven gear can be stably transmitted to the roller, thus completing the roller drive and transporting the cylinder head again. No clamping or limiting devices are required during this process. At the same time, this start-stop method can effectively avoid the friction of the roller on the cylinder head during testing, ensuring the safety of the bottom of the cylinder head.

[0056] This application provides a conveying device for detecting the protrusion height of fuel injectors. This effectively solves the technical problem of existing conveying devices for cylinder heads under test, which cannot freely adjust the roughness of the conveyor belt as needed and easily cause wear to the cylinder head. In existing conveying devices for cylinder heads under test, the rollers and anti-slip sleeves are connected by an interlocking method, and threads are provided on the outer wall of the anti-slip sleeves to increase their surface roughness. This allows for control over whether the anti-slip sleeves are fitted outside the rollers, thereby improving the device's applicability. Furthermore, by using a connecting plate connected to the anti-slip sleeves and a knob on the protective plate, rotating the knob drives the anti-slip sleeves connected to the connecting plate to move synchronously, thus achieving the purpose of freely adjusting the surface roughness of the conveying device. This allows for adjustment of the surface roughness of the conveying device according to the processing conditions of the cylinder head or the workpiece being transported, thereby adapting to various processing requirements and improving the device's applicability.

[0057] Example 1

[0058] The technical solution in this application embodiment effectively solves the technical problem that existing conveyor devices for cylinder heads under test cannot freely adjust the roughness of the conveyor belt as needed, and are prone to causing wear to the cylinder head. The overall idea is as follows:

[0059] To address the problems existing in the prior art, the present invention provides a conveying device for detecting the protrusion height of an injector. This conveying device mainly consists of three parts: first, a supporting structure, such as a bracket 11, for supporting and bearing the conveying device; second, a conveying component for providing conveying force to the cylinder head 2, which employs two interlocking rollers 32 and an anti-slip sleeve 33. The rollers 32 have smooth surfaces, suitable for cylinder heads 2 coated with anti-corrosion paint, as the surface of the cylinder head 2 already has a certain anti-corrosion coating after coating. If a certain degree of roughness is present, and the same rough roller 32 is used for support and transportation, it will cause wear to the bottom of the cylinder head 2 during injector testing. Conversely, the anti-slip sleeve 33 has anti-slip threads on its surface. By setting anti-slip threads to increase the roughness of the anti-slip sleeve 33, the friction between the roller 32 and the cylinder head 2 can be increased during transportation. This is mainly suitable for polished cylinder heads 2. Since the surface of the polished cylinder head 2 is smooth, if a smooth roller 32 is used to support and transport the cylinder head 2... The friction between the cylinder head 2 and the roller 32 is relatively small. If the cylinder head 2 is impacted or accidentally touched, it will slide, potentially causing misalignment. Therefore, a roller 32 with a higher roughness is needed to ensure stable transport. This is achieved by using interlocking rollers 32 and anti-slip sleeves 33. During normal use, the anti-slip sleeve 33 is located on one side of the roller 32 and does not participate in the transport of the cylinder head 2. Conversely, when the anti-slip sleeve 33 is pushed towards the roller 32, it... The sliding sleeve 33 participates in the transport of the cylinder head 2, thereby adjusting the surface roughness of the conveying component; thirdly, there is a switching component 5 used to control whether the roller 32 rotates. The switching component 5 can remove or connect the roller 32 at a specific location from the overall conveying device. Therefore, during inspection, the roller 32 at the bottom of the cylinder head 2 can be adjusted to prevent rotation, facilitating the inspection and positioning of the cylinder head 2. Furthermore, by stopping the rotation of the roller 32, the roller 32 can be prevented from rotating relative to the bottom of the cylinder head 2. The specific structure is as follows:

[0060] The load-bearing structure includes a bracket 11, with a protective plate 12 disposed on the top and near both sides of the bracket 11. The extending direction of the protective plate 12 is consistent with the length direction of the bracket 11. When the bracket 11 is transported to the cylinder head 2, the protective plates 12 are respectively located on both sides of the cylinder head 2. Figure 1 As shown, the main motor 14 and the component box are positioned on one side of the bracket 11. A drive gear 15 is mounted on the output shaft of the main motor 14, and the drive gear 15 is connected to the driven gear 13 inside the protective plate 12 via a chain 16. The driven gear 13 is connected to the roller 32 on the bracket 11. Figure 9As shown, the main motor 14 drives the drive gear 15 to rotate, which in turn drives the chain 16 and the driven gear 13 meshing with the chain 16 to move. The driven gear 13 then drives the roller 32 to rotate, thereby providing a transmission force to the cylinder head 2.

[0061] The conveying component mainly consists of interlocking rollers 32 and anti-slip sleeves 33. Grooves are symmetrically formed on the top of the support 11 near both sides, and the rollers 32 are placed in these grooves. A central shaft 31 connects the two opposing rollers 32 and is inserted into the support 11. Figure 1 As shown, the two ends of the central shaft 31 extend into the protective plates 12 on both sides of the bracket 11, and are connected to the inner wall of the protective plates 12 via bearings. Rollers 32 are connected to the central shaft 31 near its ends, and the surface of the central shaft 31 protrudes from the plane containing the top of the bracket 11. Figure 2 As shown, when one roller 32 rotates, it can drive the other roller 32 to rotate synchronously, facilitating the control of the subsequent switching component 5. A through hole is then provided on the side of the protective plate 12 facing the groove, and this through hole is connected to the interior of the protective plate 12. This allows the anti-slip sleeve 33 to slide into the through hole on the protective plate 12 when the anti-slip sleeve 33 is slid towards the side of the roller 32 away from the bracket 11. Figure 1 As shown in the enlarged view, when it is necessary to increase the friction between the roller 32 and the cylinder head 2, the anti-slip sleeve 33 is pushed in the direction of the roller 32, so that the anti-slip sleeve 33 can replace the roller 32 in contact with the bottom of the cylinder head 2.

[0062] The reason for using two different roughness switching methods is that during injector testing, the injector is pre-installed on cylinder head 2, such as... Figure 1As shown, after installation, the cylinder head 2, which supports the injector, is tested by testing equipment. However, the cylinder head 2, which supports the injector, is divided into two categories according to the processing sequence. One type uses the freshly formed cylinder head 2 as the carrier for the injector. Testing at this stage is necessary to ensure that the mounting holes on the cylinder head 2 surface correspond and fit the injector. However, because the bottom of the injector is smooth, if a similarly smooth roller 32 is used as the transport structure for the cylinder head 2, even slight force will cause the injector to shift. Therefore, a rougher anti-slip sleeve 33 is needed to contact the cylinder head 2 to ensure that the cylinder head 2 can move normally without shifting. The other type involves the cylinder head 2 being processed... After completion and inspection, the machining steps of cylinder head 2 are complete. The reason for inspection at this stage is to check the compatibility between the two after the fuel injector is assembled. However, unlike the previous stage, the cylinder surface has been treated and has a certain friction. If a rough anti-slip sleeve 33 is used as the transport structure of cylinder head 2, when cylinder head 2 moves to the inspection station, it stops moving under the limit of the fixture. Due to its large weight, it cannot be lifted off the conveyor belt when it is stopped. Therefore, even during inspection, its bottom will still roll on the roller 32, and the anti-slip sleeve 33 will cause wear on the bottom of cylinder head 2. Therefore, in this state, a smooth roller 32 is required.

[0063] To ensure synchronized movement of all anti-slip sleeves 33 during use, reducing adjustment difficulty and time, a rectangular connecting plate 34 is installed inside the protective plate 12. This connecting plate 34 is connected to the knobs 351 at both ends of the protective plate 12. Figure 1 As shown, the head of the knob 351 is located on the outside of the protective plate 12, while the screw part passes through the protective plate 12 and enters its interior, connecting with the connecting plate 34 located inside it. The screw is connected to the end of the protective plate 12, and a positioning plate 352 is provided at the end of the screw inserted into the protective plate 12. The positioning plate 352 is connected to the inner wall of the protective plate 12, forming a shape as shown in the diagram. Figure 2 and Figure 3 As shown, by rotating the knob 351 on the connecting plate 34, since the screw of the knob 351 is threadedly connected to the connecting plate 34, rotating the knob 351 can drive the connecting plate 34 to extend along the length direction of the screw. The length direction of the screw is consistent with the direction of the anti-slip sleeve 33 towards the roller 32. Therefore, rotating the knob 351 can control the connecting plate 34 to be pushed towards the roller 32. Since the side of the connecting plate 34 facing the roller 32 is connected to the anti-slip sleeve 33 via a bearing, when the connecting plate 34 moves towards the roller 32, it can control the anti-slip sleeve 33 to be fitted onto the roller 32. Figure 3As shown, at this time, the anti-slip sleeve 33 is sleeved on the outside of the roller 32. When the cylinder head 2 moves along the bracket 11, the cylinder head 2 contacts the anti-slip sleeve 33 sleeved on the outside of the roller 32, thereby using the anti-slip sleeve 33 with a larger roughness as a support structure for the cylinder head 2.

[0064] Conversely, when a roller 32 with a lower surface roughness is required, rotating the knob 351 in the opposite direction controls the screw to move the connecting plate 34 and the anti-slip sleeve 33 connected to the connecting plate 34 to the side away from the roller 32. Figures 3 to 2 As shown, the anti-slip sleeve 33 moves out of the outside of the roller 32, exposing the roller 32 on its bracket 11. In this way, when the cylinder head 2 is transported, the cylinder head 2 will come into contact with the smooth roller 32, thereby changing the friction between the cylinder head 2 and the roller 32.

[0065] To improve the sliding stability of the anti-slip sleeve 33 and the stability of the connection between the anti-slip sleeve 33 and the roller 32, a mating groove 353 is formed on the outer wall of the roller 32 near the location of the anti-slip sleeve 33, corresponding to the mating pin 354 on the inner wall of the anti-slip sleeve 33. When the roller 32 is in contact with the anti-slip sleeve 33, the mating pin 354 on the inner wall of the anti-slip sleeve 33 can be inserted into the mating groove 353 on the outer wall of the roller 32. When the roller 32 rotates, torque can be transmitted to the anti-slip sleeve 33 through the insertion relationship between the mating pin 354 and the mating groove 353, thus preventing slippage. The sleeve 33 rotates synchronously. Based on the above, we also provide an inner ring 356 at the end of the anti-slip sleeve 33 opposite to the connecting plate 34. The inner ring 356 can slide along the groove 355 on the outer wall of the central shaft 31. In this way, the central shaft 31 can rotate together with the anti-slip sleeve 33 during rotation. Since the anti-slip sleeve 33 and the connecting plate 34 are connected by a bearing, the anti-slip sleeve 33 sleeved on the outside of the central shaft 31 can rotate together when the central shaft 31 rotates, so as to ensure that the mating pin 354 on the inner wall of the anti-slip sleeve 33 corresponds to the mating groove 353 on the outer wall of the roller 32.

[0066] In practical implementation, when the polished cylinder head 2 needs to be transported, the knob 351 on the rotating connecting plate 34 is rotated. Since the screw of the knob 351 is connected to the connecting plate 34 by a thread, rotating the knob 351 can drive the connecting plate 34 to extend along the length direction of the screw. The length direction of the screw is consistent with the direction of the anti-slip sleeve 33 towards the roller 32. Therefore, rotating the knob 351 can control the connecting plate 34 to push towards the roller 32. Since the side of the connecting plate 34 facing the roller 32 is connected to the anti-slip sleeve 33 by a bearing, when the connecting plate 34 moves towards the roller 32, it can control the anti-slip sleeve 33 to be fitted onto the roller 32. Figures 2 to 3As shown, at this time, the anti-slip sleeve 33 is sleeved on the outside of the roller 32. When the cylinder head 2 moves along the bracket 11, the cylinder head 2 contacts the anti-slip sleeve 33 sleeved on the outside of the roller 32, thereby using the anti-slip sleeve 33 with a larger roughness as a support structure for the cylinder head 2.

[0067] Conversely, when a roller 32 with lower roughness is required, rotating the knob 351 in the opposite direction controls the screw to move the connecting plate 34 and the anti-slip sleeve 33 connected to the connecting plate 34 away from the roller 32. Figures 3 to 2 As shown, the anti-slip sleeve 33 moves out of the outside of the roller 32, exposing the roller 32 on its bracket 11. In this way, when the cylinder head 2 is transported, the cylinder head 2 will come into contact with the smooth roller 32, thereby changing the friction between the cylinder head 2 and the roller 32.

[0068] Example 2

[0069] Based on Example 1, this application provides a feasible limiting structure to achieve auxiliary fixing and prevent friction between the rolling roller and the bottom of the cylinder head during cylinder head inspection. The overall concept is as follows:

[0070] The switching element 5 is located on one side of the protective plate 12. To freely switch the movement of the roller 32, the two need to be connected via the switching element 5. Based on the above, it can be seen that a relatively independent power source is required. Therefore, a cylindrical docking cylinder 4 is connected to the inside of the protective plate 12 via a bearing, corresponding to the end of the central shaft 31. Then, the driven gear 13, which rotates synchronously with the main motor 14, is installed on the docking cylinder 4. Figure 5 and Figure 7 As shown, therefore, it is only necessary to control whether the docking cylinder 4 is connected to the central shaft 31, so that the power received by the docking cylinder 4 can be transmitted to the central shaft 31 and the roller 32 corresponding to the central shaft 31, so that the roller 32 can rotate.

[0071] To ensure the connection between the docking cylinder 4 and the central shaft 31 when inserted into the end of the docking cylinder 4, upper limit strips are provided inside the docking cylinder 4, on the inner wall of the corresponding end of the central shaft 31 and the docking cylinder 4, and on the outer wall of the connecting pin 56. When the connecting pin 56 is inserted into the docking cylinder 4, the limit strips between them interlock. Similarly, when the connecting pin 56 is inserted into the end of the central shaft 31, the limit strips on the outside of the connecting pin 56 and the limit strips at the end of the central shaft 31 interlock. When the connecting pin 56 is inserted between the ends of the docking cylinder 4 and the central shaft 31, the docking cylinder 4 and the central shaft 31 can be moved together. Figure 12 and Figure 13 As shown.

[0072] The switching component 5 mainly consists of corresponding electromagnetic rings 52 and movable rings 53. Utilizing the characteristics of the internal electromagnetic coils of the electromagnetic rings 52, the positive and negative terminals of the electromagnetic rings 52 are connected to an external power source via wires, and a switch is installed on the wires to control the start and stop of the electromagnetic rings 52. When energized, the electromagnetic rings 52 generate magnetism, attracting the corresponding movable rings 53 before and after them. To be compatible with the electromagnetic rings 52, the movable rings 53 are made of ferrous or magnetic materials. Therefore, when the electromagnetic rings 52 are energized, they can pull the movable rings 53 towards the direction of the electromagnetic rings 52. To utilize this electromagnetic function, a connecting pin 56 is provided on the movable rings 53 facing the protective plate 12. Figure 10 and Figure 11 As shown, the docking cylinder 4 is connected and separated from the central shaft 31 by the back-and-forth movement of the connecting pin 56; the center of the movable ring 53 is connected to the connecting seat 55 at the rear end of the connecting pin 56 by a bearing. In this way, when the connecting pin 56 is inserted between the docking cylinder 4 and the end of the central shaft 31 and rotates with the central shaft 31, the torque is prevented from being transmitted to the protective cover 51.

[0073] During contraction, power is supplied to the electromagnetic ring 52, causing it to become magnetic. This magnetic attraction draws the movable ring 53 at its front end, causing it to pull the connecting pin 56 inwards towards the interior of the protective cover 51. Figure 11 As shown, at this time, the return spring 54, located between the electromagnetic ring 52 and the movable ring 53, is compressed, as follows. Figure 11 The lower half of the structure is shown.

[0074] When the electromagnetic ring 52 is extended, the power is de-energized, and the magnetism generated by the electromagnetic ring 52 disappears. Meanwhile, when the connecting pin 56 is in a retracted state, the return spring 54 inside the protective cover 51 is compressed. Therefore, when the electromagnetic ring 52 is de-energized, the movable ring 53 is pushed closer to the protective plate 12 under the action of the return spring 54. Figure 11 The upper part is shown. To prevent the movable ring 53 from moving out of the protective cover 51, a retaining ring 58 is provided at the opening of the protective cover 51 on the inner wall of the protective cover 51, and the retaining ring 58 corresponds to the side of the movable ring 53 facing the protective plate 12. Under the action of the return spring 54, the movable ring 53 is in contact with the outer wall of the retaining ring 58, thereby limiting the range of motion of the movable ring 53.

[0075] In order to ensure the stability of the sliding of the movable ring 53, a guide strip 57 is provided on the inner wall of the protective cover 51, which corresponds to the notch on the edge of the movable ring 53. In this way, when the movable ring 53 slides back and forth, the movable ring 53 can slide along the length of the guide strip 57, thereby preventing the movable ring 53 from sliding.

[0076] In the specific implementation process, such as Figures 12 to 13As shown, when it is necessary to separate the central shaft 31 from the driven gear 13 that follows the main motor 14, the electromagnetic ring 52 is energized, causing it to become magnetic and attract the movable ring 53 located at its front end. Since the movable ring 53 is connected to the connecting pin 56, when the movable ring 53 is attracted, it causes the connecting pin 56 to retract into the protective cover 51. Figure 11 As shown, at this time, the connecting pin 56 moves out of the hole at the end of the central shaft 31 and retracts to the position of the docking cylinder 4. At this time, the driven gear 13 rotates without affecting the roller 32. Moreover, since the driven gear 13 is connected to the inner wall of the protective plate 12 through the bearing, and the connecting seat 55 at the rear end of the connecting pin 56 is connected to the movable ring 53 through the bearing, the connecting pin 56 will not affect the driven gear 13 when it rotates with the main motor 14. The return spring 54 located between the electromagnetic ring 52 and the movable ring 53 is compressed, as... Figure 11 The lower half of the structure is shown.

[0077] When it is necessary to control the main motor 14 to output torque to the central shaft 31 and the roller 32 thereon, the electromagnetic ring 52 is de-energized. At this time, the magnetism generated by the electromagnetic ring 52 disappears, and when the connecting pin 56 is in a retracted state, the return spring 54 inside the protective cover 51 is compressed. Therefore, when the electromagnetic ring 52 is de-energized, the movable ring 53 is pushed towards the position of the protective plate 12 under the action of the return spring 54. Figure 11 As shown in the upper part. Figure 13 As shown Figure 12 As shown, under the thrust of the return spring 54, the connecting pin 56 is inserted from the docking cylinder 4 into the hole at the end of the central shaft 31. When the connecting pin 56 is inserted between the docking cylinder 4 and the end of the central shaft 31, since upper limit strips are provided inside the docking cylinder 4, on the inner wall of the corresponding end of the central shaft 31 and the docking cylinder 4, and on the outer wall of the connecting pin 56, the upper limit strip of the connecting pin 56 and the upper limit strip of the central shaft 31 interweave, thus linking the docking cylinder 4 and the central shaft 31. Figure 12 and Figure 13 As shown.

[0078] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
