Description

Technical Field

[0001] This application relates to the field of gear technology, and in particular to gear angular position detection mechanisms, adjustment devices, and gear assembly systems. Background Technology

[0002] Gear transmission is a mechanical transmission method that uses the meshing of gear teeth to transmit power and motion. Multiple gears can transmit the rotational motion, torque and power of one shaft to another through the meshing of their teeth.

[0003] Gear meshing requires high accuracy in the angular position of each gear. The angular position of a gear is the amount of rotation of the gear around its own axis. If the angular position of a gear deviates too much from the predetermined position, it can easily lead to large meshing errors, which in turn can cause problems such as excessive friction between gears, vibration, and reduced transmission efficiency.

[0004] In related technologies, the angular position of gears is often checked by human observation or manual measurement. This method has low efficiency and is also affected by human subjectivity, resulting in poor accuracy. Utility Model Content

[0005] This application provides a gear angular position detection mechanism, adjustment device, and gear assembly system, which can improve the efficiency and accuracy of gear angular position detection.

[0006] In a first aspect, this application provides a gear angular position detection mechanism, which includes a mounting base, a probe, and a detection module. The probe is slidably connected to the mounting base along its own axial direction, and a first end of the probe extends out of the mounting base along its axial direction. The detection module is configured to detect the length by which the first end of the probe extends out of the mounting base.

[0007] The gear angular position detection mechanism provided in this application has a probe that is slidably connected to a mounting base along its own axial direction. This allows the length of the first end of the probe extending axially from the mounting base to be adjustable. This ensures that the axial direction of the probe is perpendicular to the gear's axis, and that the first end of the probe contacts the outer edge of the gear along the direction it extends from the mounting base. The length of the probe extending from the mounting base reflects the gear's angular position. A shorter extension distance indicates the first end is close to the gear's tooth tip, while a longer extension distance indicates the first end is close to the gear's tooth root. In other words, the length of the probe extending from the mounting base indicates whether the tooth tip or the tooth root is facing the probe, thus reflecting the gear's angular position. Alternatively, the first end of the probe can be embedded in a groove of a gear component (which can refer to a gear or a part containing gears, such as a gear shaft). A shorter extension distance indicates the first end is close to the top of the groove, while a longer extension distance indicates the first end is close to the bottom of the groove. The detection module is used to detect the length of the first end of the probe extending out of the mounting base, and the detection result of the module can reflect the angular position of the gear. Therefore, this application provides a gear angular position detection mechanism. The detection module can automatically detect the gear angular position based on the length of the first end of the probe extending out of the mounting base, without the need for human observation or manual detection, thus improving the efficiency and accuracy of detection.

[0008] In some alternative implementations of this application, the gear angular position detection mechanism further includes an elastic element disposed between the mounting base and the probe element, configured to drive the first end of the probe element to move away from the mounting base.

[0009] In this way, the elastic element can apply a constant force towards the gear component to the probe, which helps to ensure close contact between the probe and the gear component and improves the accuracy of the detection. Moreover, compared with mechanisms such as power cylinders or linear motors, the elastic element has a simpler structure. Using the elastic element as the structure for applying constant force helps to simplify the structure of the gear angular position detection mechanism and reduce its cost.

[0010] In some alternative implementations of this application, the sidewall of the probe protrudes to form abutment, the elastic member is sleeved on the probe, the first end of the elastic member abuts against the abutment along the axial direction of the probe, and the second end of the elastic member abuts against the mounting base along the axial direction of the probe.

[0011] By fitting the elastic element onto the detector, the installation reliability of the elastic element is high, and the elastic element is not prone to bending or displacement. By supporting the elastic element axially between the abutment and the mounting base, the elastic element can apply a constant force toward the gear component to the detector, ensuring tight contact between the detector and the gear component.

[0012] In some alternative implementations of this application, the first end of the probe is formed with a ball head, and the first end of the elastic member abuts against the ball head along the axial direction of the probe.

[0013] In this way, the first end of the probe has a ball head. On the one hand, the ball head can be inserted into the tooth groove or recess of the gear and abut against the groove wall. On the other hand, the ball head can also abut against the elastic element. The ball head is fully utilized, and the probe does not need to have other structures for abutting against the elastic element, which helps to simplify the structure and improve its compactness. The ball head abuts against the groove wall. On the one hand, the outer surface of the ball head is relatively smooth, which helps to reduce damage to the gear. On the other hand, the ball head has an automatic centering function in the tooth groove or recess, which can reduce alignment errors and improve detection accuracy.

[0014] Secondly, this application provides a gear angle position adjustment device, which includes a drive mechanism and a gear angle position detection mechanism provided in the first aspect of this application. The drive mechanism is connected to a detection module and is configured to drive a gear component to rotate relative to the mounting base around its own axis according to the detection result of the detection module. The axis of the gear component is perpendicular to the axis of the detector component, and the direction from the gear component to the detector component is opposite to the direction in which the first end of the detector component extends out of the mounting base.

[0015] The gear angular position adjustment device provided in this application, including the gear angular position detection mechanism, achieves the same technical effect, namely, improving the accuracy of gear angular position detection. Furthermore, the gear angular position adjustment device provided in this application has a drive mechanism that can drive the gear component to rotate relative to the mounting base around its own axis. That is, the drive mechanism can adjust the angular position of the gear. The drive mechanism is connected to the detection module, and can drive the gear component to rotate based on the detection results of the detection module. When the first end of the probe extends a preset length beyond the mounting base, the drive mechanism stops driving the gear component to rotate relative to the mounting base, completing the angular position adjustment. The detection module has high efficiency and accuracy in detecting the gear angular position, resulting in high efficiency and accuracy in the drive mechanism's adjustment of the gear angular position.

[0016] In some alternative implementations of this application, the drive mechanism includes a fixed part and a rotating shaft. The fixed part is fixed relative to the mounting base, and the rotating shaft is rotatably connected to the fixed part about its own axis. The rotating shaft is configured to cooperate with a gear component.

[0017] By fixing the fixed part relative to the mounting base, and rotating the shaft around its own axis and connecting it to the fixed part, the drive mechanism has a simpler structure, lower cost, and higher reliability. By having the rotating shaft cooperate with a gear component to drive the gear component to rotate relative to the mounting base, the connection between the rotating shaft and the gear component is simpler, lower in cost, and higher in reliability.

[0018] In some alternative implementations of this application, the gear angular position adjustment device further includes a receiving member, which is fixed relative to the mounting base. The receiving member forms a receiving cavity, which is configured to receive a gear. The receiving cavity has an opening, the orientation of which is opposite to the orientation of the first end of the probe. The first end of the probe is configured to extend into the receiving cavity through the opening.

[0019] By placing the gear component within the receiving cavity, the receiving component protects the gear component during gear angle position adjustment, reducing external interference and improving adjustment efficiency and the accuracy of the adjusted gear angle position. By allowing the first end of the probe to extend into the receiving cavity through an opening to contact the gear component, most of the gear angle position detection mechanism can be located outside the receiving cavity. This reduces the likelihood of interference between the gear component and other structures of the gear angle position detection mechanism (excluding the probe), improving adjustment efficiency. Furthermore, it eliminates the need for an excessively large receiving component, reducing material consumption.

[0020] In some alternative implementations of this application, the receiving member includes a cylindrical portion, at least one end of which is open, the inner cavity of which is configured to receive the gear member, and an opening is formed in the side wall of the cylindrical portion.

[0021] By opening at least one end of the cylinder, the gear component can be inserted into the cylinder through the opening at at least one end, making the process of placing the gear component into the cylinder more convenient. By forming an opening on the side wall of the cylinder, the first end of the probe can extend into the receiving cavity through the opening to contact the gear component, thereby realizing the detection of the gear angular position.

[0022] In some optional implementations of this application, the axial direction of the probe is horizontal, and the gear angular position adjustment device further includes a placement stage, which is disposed in the receiving cavity. The placement stage is rotatably connected to the receiving component, and the axis of relative rotation between the placement stage and the receiving component is parallel to the vertical direction.

[0023] By providing a placement platform within the receiving cavity, the gear component can be placed on the platform while it is located within the receiving cavity. This prevents the gear component from tipping over, sliding, or shaking, thereby improving the accuracy of gear angle adjustment. The placement platform is rotatably connected to the receiving component, allowing the platform to rotate together with the gear component when it rotates relative to the receiving component. This reduces friction between the gear component and the placement platform, minimizing damage to the gear component.

[0024] Thirdly, this application provides a gear assembly system, which includes a placement fixture, a conveying device, and a gear angular position adjustment device provided in the second aspect of this application. The placement fixture is configured to place gear parts, and the conveying device connects the gear angular position adjustment device and the placement fixture, and is configured to convey the gear parts to the placement fixture by the gear angular position adjustment device.

[0025] The gear assembly system provided in this application, including the gear angular position adjustment device provided in the second aspect of this application, can achieve the same technical effect, namely, improving the efficiency and accuracy of gear angular position adjustment. Furthermore, in the gear assembly system provided in this application, the conveying device can transport the gear from the gear angular position adjustment device to the placement fixture. After adjustment by the gear angular position adjustment device, the gear has high angular position accuracy, and is then transported by the conveying device to the placement fixture for assembly with other gears, resulting in a gear set with high meshing accuracy.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3 This application provides a gear angular position detection mechanism, which includes a mounting base 1, a probe 2, and a detection module. The probe 2 is slidably connected to the mounting base 1 along its own axial direction, and a first end of the probe 2 extends out of the mounting base 1 along its axial direction. The detection module is configured to detect the length by which the first end of the probe 2 extends out of the mounting base 1.

[0035] The gear angular position detection mechanism provided in this application embodiment has a probe 2 that is slidably connected to the mounting base 1 along its own axial direction, so that the length of the first end of the probe 2 extending out of the mounting base 1 along the axial direction is adjustable. In this way, the axial direction of the probe 2 is perpendicular to the axis of the gear, and the first end of the probe 2 contacts the outer edge of the gear along the direction of extending out of the mounting base 1. The length of the probe 2 extending out of the mounting base 1 can reflect the angular position of the gear. If the first end of the probe 2 extends a shorter distance, that is, the first end of the probe 2 is located near the tooth tip of the gear, and if the first end of the probe 2 extends a longer distance, that is, the first end of the probe 2 is located near the tooth root of the gear, that is, the length of the probe 2 extending out of the mounting base 1 can reflect whether the tooth tip or the tooth root is facing the probe 2, that is, it can reflect the angular position of the gear. The first end of the probe 2 can also be embedded in the groove 011 containing the gear component 01 along the direction extending out of the mounting base 1. The gear component 01 can refer to a gear or a part containing gears, such as a gear shaft. The first end of the probe 2 can extend a shorter distance, i.e., the first end of the probe 2 is located near the top of the groove 011, or it can extend a longer distance, i.e., the first end of the probe 2 is located near the bottom of the groove 011. The detection module is used to detect the length of the first end of the probe 2 extending out of the mounting base 1, and the detection result of the detection module can reflect the angular position of the gear. Therefore, this embodiment of the application provides a gear angular position detection mechanism. The detection module can automatically detect the angular position of the gear based on the length of the first end of the probe 2 extending out of the mounting base 1, without requiring human observation or manual detection, thus improving the efficiency and accuracy of the detection.

[0036] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, during the detection process, the axial direction of the probe 2 can be made to intersect with the axis of the gear, that is, the axial direction of the probe 2 is a radial direction of the gear.

[0037] Please refer to Figure 1 , Figure 2 and Figure 3 It should be noted that, in this embodiment of the application, the first end of the probe 2 is one end of the probe 2 along the axial direction of the probe 2.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 It should be explained that, in the embodiments of this application, the length by which the first end of the probe 2 extends out of the mounting base 1 refers to the length by which the first end of the probe 2 extends out of the mounting base 1 along the axial direction of the probe 2.

[0039] In some embodiments of this application, the detection module may be a displacement sensor, etc.

[0040] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the gear angular position detection mechanism further includes an elastic element, which is disposed between the mounting base 1 and the probe 2 and configured to drive the first end of the probe 2 to move away from the mounting base 1.

[0041] In this way, the elastic element can apply a constant force towards the gear component 01 to the probe 2, which helps to ensure close contact between the probe 2 and the gear component 01 and improves the accuracy of detection. Moreover, compared with mechanisms such as power cylinders or linear motors, the structure of the elastic element is relatively simple. Using the elastic element as the structure for applying constant force helps to simplify the structure of the gear angular position detection mechanism and reduce costs.

[0042] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the sidewall of the probe 2 protrudes to form abutment, and an elastic member is sleeved on the probe 2. The first end of the elastic member abuts against the abutment along the axial direction of the probe 2, and the second end of the elastic member abuts against the mounting base 1 along the axial direction of the probe 2.

[0043] By fitting the elastic element onto the detector 2, the installation reliability of the elastic element is high, and the elastic element is not prone to bending or displacement. By supporting the elastic element axially between the abutment and the mounting base 1, the elastic element can apply a constant force toward the gear 01 to the detector 2, ensuring close contact between the detector 2 and the gear 01.

[0044] Please refer to Figure 1 , Figure 2 and Figure 3 It should be explained that in the embodiments of this application, the axial direction of the elastic element, i.e. the elastic direction of the elastic element, is the same as the axial direction of the probe 2. The elastic element is sleeved on the probe 2, which means that the elastic element is sleeved on the probe 2 along the axial direction.

[0045] Please refer to Figure 1 , Figure 2 and Figure 3 It is understood that, in the embodiments of this application, when the elastic element is in a compressed state, a constant force toward the gear element 01 can be applied to the first end of the elastic element. In some embodiments of this application, the elastic element may be a compression spring.

[0046] Please refer to Figure 1 , Figure 2 and Figure 3 It should be explained that, in the embodiments of this application, the first end and the second end of the probe 2 are the two opposite ends of the probe 2 along the axial direction of the probe 2.

[0047] Please refer to Figure 1 , Figure 3 and Figure 4 In some embodiments of this application, the first end of the probe 2 is formed with a ball head 21, and the first end of the elastic member abuts against the ball head 21 along the axial direction of the probe 2. Thus, the ball head 21 at the first end of the probe 2 serves two purposes: firstly, it can be inserted into the tooth groove of a gear or into the groove 011 containing the gear component 01, abutting against the groove wall of the tooth groove or groove 011; secondly, it also abuts against the elastic member. The ball head 21 is fully utilized, and the probe 2 does not need other structures for abutting against the elastic member, which simplifies the structure and improves its compactness. The ball head 21 abuts against the groove wall of the tooth groove or groove 011. Firstly, the outer surface of the ball head 21 is relatively smooth, which helps reduce damage to the gear component 01. Secondly, the ball head 21 has an automatic alignment function within the tooth groove or groove 011, which reduces alignment errors and improves detection accuracy.

[0048] Please refer to Figure 1 , Figure 3 and Figure 4 In some embodiments of this application, the gear component 01 can be a gear shaft, and the groove 011 can be formed on the side wall of the shaft portion of the gear shaft.

[0049] Please refer to Figure 3 , Figure 5 and Figure 6 In some embodiments of this application, the mounting base 1 has a mounting hole, and the probe 2 slides within the mounting hole. This simplifies the connection between the probe 2 and the mounting base 1, reduces cost, and increases reliability. The mounting hole can be a through hole or a blind hole. In some embodiments of this application, the second end of the probe 2 may be inserted into the mounting hole.

[0050] Understandable, Figure 5 In the paper, the direction in which the probe 2 extends out of the mounting base 1, i.e., the orientation of the first end of the probe 2, is perpendicular to the paper and outwards.

[0051] Please refer to Figure 1 , Figure 2 and Figure 3 This application provides a gear angle position adjustment device, which includes a drive mechanism 4 and a gear angle position detection mechanism. The drive mechanism 4 is connected to a detection module and is configured to drive the gear component 01 to rotate around its own axis relative to the mounting base 1 according to the detection result of the detection module. The axis of the gear component 01 is perpendicular to the axis of the detector component 2, and the direction from the gear component 01 to the detector component 2 is opposite to the direction in which the first end of the detector component 2 extends out of the mounting base 1.

[0052] The gear angular position adjustment device provided in this application embodiment, including the gear angular position detection mechanism provided in this application embodiment, can achieve the same technical effect, namely, improving the accuracy of gear angular position detection. Furthermore, in the gear angular position adjustment device provided in this application embodiment, the drive mechanism 4 can drive the gear component 01 to rotate relative to the mounting base 1 around its own axis. That is, the drive mechanism 4 can adjust the angular position of the gear. The drive mechanism 4 is connected to the detection module, and can drive the gear component 01 to rotate according to the detection result of the detection module. When the first end of the probe 2 extends beyond the mounting base 1 by a preset length, the drive mechanism 4 stops driving the gear component 01 to rotate relative to the mounting base 1, completing the angular position adjustment. The detection module has high efficiency and accuracy in detecting the gear angular position, resulting in high efficiency and accuracy in the gear angular position adjustment by the drive mechanism 4.

[0053] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the drive mechanism 4 includes a fixed part 41 and a rotating shaft 42. The fixed part 41 is fixed relative to the mounting base 1, and the rotating shaft 42 is rotatably connected to the fixed part 41 around its own axis. The rotating shaft 42 is configured to cooperate with the gear component 01.

[0054] By fixing the fixed part 41 relative to the mounting base 1, and rotating the shaft 42 around its own axis and rotatably connecting it to the fixed part 41, the structure of the drive mechanism 4 is relatively simple, with low cost and high reliability. By cooperating with the gear component 01 to drive the gear component 01 to rotate relative to the mounting base 1, the connection between the shaft 42 and the gear component 01 is simple, with low cost and high reliability.

[0055] Please refer to Figure 1 , Figure 2 and Figure 3 It is understood that in the embodiments of this application, the rotating shaft 42 is coaxial with the gear component 01. In some embodiments of this application, the rotating shaft 42 can abut against the gear component 01 axially to drive the gear component 01 to rotate relative to the mounting base 1 around its own axis. In some embodiments of this application, the rotating shaft 42 can mate with the center hole of the gear component 01. One of the sidewalls of the rotating shaft 42 and the sidewall of the center hole forms a protrusion, and the other forms a limiting groove. The protrusion and the limiting groove mate with each other so that the rotating shaft 42 can drive the gear component 01 to rotate relative to the mounting base 1 around its own axis.

[0056] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the drive mechanism 4 may include an electric motor, the output shaft of which is at least a portion of the rotating shaft 42. Electric motors are a relatively mature technology, making them a cost-effective option for drive mechanism 4.

[0057] Please refer to Figure 3 , Figure 7 and Figure 8 In some embodiments of this application, the gear angle position adjustment device further includes a receiving member 5, which is fixed relative to the mounting base 1. The receiving member 5 forms a receiving cavity 51, which is configured to receive the gear member 01. The receiving cavity 51 has an opening 52, the orientation of which is opposite to the orientation of the first end of the probe member 2. The first end of the probe member 2 is configured to extend into the receiving cavity 51 through the opening 52.

[0058] By placing the gear component 01 inside the receiving cavity 51, the receiving component 5 can protect the gear component 01 during the adjustment of the gear's angular position, which helps reduce external interference and improves adjustment efficiency and the accuracy of the gear's angular position after adjustment. By allowing the first end of the probe 2 to extend into the receiving cavity 51 through the opening 52 to contact the gear component 01, most of the structure of the gear angular position detection mechanism can be located outside the receiving cavity 51. On the one hand, this makes it less likely for the gear component 01 to interfere with other structures of the gear angular position detection mechanism except for the probe 2, which helps improve adjustment efficiency. On the other hand, it also means that the receiving component 5 does not need to be too large, which helps reduce the material consumption of the receiving component 5.

[0059] Please refer to Figure 3 , Figure 7 and Figure 8 It should be explained that, in the embodiments of this application, the orientation of the first end of the probe 2 refers to the direction in which the first end of the probe 2 extends out of the mounting base 1, which is parallel to the axial direction of the probe 2.

[0060] Please refer to Figure 3 , Figure 7 and Figure 8 In some embodiments of this application, the first end of the probe 2 is further configured to disengage from the receiving cavity 51 through the opening 52. In this way, after the angular position of one gear 01 is adjusted, the first end of the probe 2 can disengage from the receiving cavity 51, making it less likely for the probe to interfere with the gear 01 during the process of placing another gear 01 into the receiving cavity 51, thus facilitating the placement of the gear 01.

[0061] Please refer to Figure 3 , Figure 7 and Figure 8 In some embodiments of this application, the receiving member 5 includes a cylindrical portion, at least one end of which is open, the inner cavity of which is configured to receive the gear member 01, and an opening 52 is formed in the side wall of the cylindrical portion.

[0062] By opening at least one end of the cylindrical portion, the gear component 01 can enter the cylindrical portion through the opening at at least one end, making the process of placing the gear component 01 into the cylindrical portion more convenient. By forming an opening 52 on the side wall of the cylindrical portion, the first end of the probe 2 can extend into the receiving cavity 51 through the opening 52 to contact the gear component 01, thereby realizing the detection of the angular position of the gear.

[0063] Please refer to Figure 3 , Figure 7 and Figure 8 In some embodiments of this application, the fixing part 41 is located outside the receiving cavity 51, and the rotating shaft 42 extends into the receiving cavity 51 through the opening at one end of the cylindrical part, cooperating with the gear component 01. In this way, most of the structure of the drive mechanism 4 can be set outside the receiving cavity 51. On the one hand, this makes it less likely for the gear component 01 and other structures of the drive mechanism 4, except for the rotating shaft 42, to interfere with each other, which is beneficial to improving adjustment efficiency. On the other hand, it also means that the receiving part 5 does not need to be too large, which is beneficial to reducing the material consumption of the receiving part 5.

[0064] Please refer to Figure 3 , Figure 7 and Figure 8 In some embodiments of this application, the axial direction of the probe 2 is horizontal, and the gear angle position adjustment device further includes a placement platform 6, which is disposed in the receiving cavity 51. The placement platform 6 is rotatably connected to the receiving member 5, and the axis of relative rotation between the placement platform 6 and the receiving member 5 is parallel to the vertical direction.

[0065] By providing a placement platform 6 within the receiving cavity 51, the gear component 01 can be placed on the placement platform 6 when it is located within the receiving cavity 51. This prevents the gear component 01 from tipping over, sliding, or shaking when placed within the receiving cavity 51, thereby improving the accuracy of angular position adjustment of the gear. The placement platform 6 is rotatably connected to the receiving component 5, so that when the gear component 01 rotates relative to the receiving component 5, the placement platform 6 can rotate together, which helps reduce the friction between the gear component 01 and the placement platform 6, thus reducing damage to the gear component 01.

[0066] Please refer to Figure 3 , Figure 7 and Figure 8 In some embodiments of this application, at least one end of the cylinder is open and the other end is closed. The turntable can be placed on the end wall of the closed end of the cylinder and can be rotatably connected to the end wall of the closed end of the cylinder. In this way, the installation reliability of the turntable and the cylinder is high.

[0067] Please refer to Figure 3 , Figure 7 and Figure 8In some embodiments of this application, the rotating shaft 42 can abut against the gear component 01 along the axial direction to drive the gear to rotate relative to the mounting base 1 around its own axis. Along the axial direction of the gear component 01, the rotating shaft 42 and the placement platform 6 can be respectively arranged on opposite sides of the gear component 01. In this way, the rotating shaft 42 and the placement platform 6 can clamp the gear component 01, making it less likely to tip over, slide, or shake when the gear component 01 is placed in the receiving cavity 51, thereby improving the accuracy of adjusting the angular position of the gear.

[0068] Please refer to Figure 3 , Figure 7 and Figure 8 In some embodiments of this application, along the axial direction of the gear component 01, the placement platform 6 is located on one side of the gear component 01, and the rotating shaft 42 extends from the other side of the gear component 01 into the central hole of the gear component 01, engaging with the central hole. The sidewall of the rotating shaft 42 and the sidewall of the central hole each have a protrusion and a limiting groove, respectively. The protrusion and the limiting groove engage with each other, enabling the rotating shaft 42 to drive the gear component 01 to rotate relative to the mounting base 1 around its own axis. This reduces the likelihood of interference between the rotating shaft 42 and the placement platform 6, and facilitates their arrangement.

[0069] Please refer to Figure 1 , Figure 2 and Figure 3 This application also provides a gear assembly system, which includes a placement fixture, a conveying device, and a gear angular position adjustment device. The placement fixture is configured to place a gear component 01. The conveying device connects the gear angular position adjustment device and the placement fixture and is configured to convey the gear component 01 to the placement fixture by the gear angular position adjustment device.

[0070] Please refer to Figure 1 , Figure 2 and Figure 3 The gear assembly system provided in this application embodiment, including the gear angular position adjustment device provided in this application embodiment, can achieve the same technical effect, namely, improving the efficiency and accuracy of gear angular position adjustment. Furthermore, in the gear assembly system provided in this application embodiment, the conveying device can transport the gear component 01 from the gear angular position adjustment device to the placement fixture. After adjustment by the gear angular position adjustment device, the gear component 01 has high angular position accuracy, and is then transported by the conveying device to the placement fixture for assembly with other gears, resulting in a gear set with high meshing accuracy.

[0071] Please refer to Figure 1 , Figure 2 and Figure 3In some embodiments of this application, the conveying device includes a frame and grippers. The frame is fixed relative to the mounting base 1, and the grippers are movably disposed on the frame and configured to grip the gear component 01. They are also capable of moving to positions corresponding to the gear angle position adjustment device and the placement fixture, respectively, so that the gear component 01 can be conveyed to the placement fixture by the gear angle position adjustment device.

[0072] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the conveying device is further configured to convey the gear component 01 from the storage area to the gear angle position adjustment device. That is, the conveying device can first convey the gear component 01 from the storage area to the gear angle position adjustment device, so that the gear angle position adjustment device adjusts the angular position of the gear component, and then the adjusted gear component 01 is conveyed by the conveying device to the placement fixture. In this way, the conveying device is fully utilized.

[0073] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the gear assembly system further includes a conveyor belt, the output end of which is connected to a gear angle position adjustment device and configured to transport the gear component 01 to the gear angle position adjustment device. Personnel can place the gear component 01 on the conveyor belt, which can automatically transport the gear component 01 to the gear angle position adjustment device. In some embodiments of this application, the output end of the conveyor belt can be connected to a receiving member 5, and the conveyor belt is configured to transport the gear component 01 into the receiving cavity 51.
