Description

Technical Field

[0001] The invention belongs to the technical field of automation equipment, and in particular relates to a gear meshing assembly device. Background Art

[0002] A reduction gearbox is a mechanical transmission device that is mainly used to reduce the speed of the engine output and increase the torque to meet the requirements of different speeds. At present, in the production and assembly of automotive motor reduction gearboxes, it is common to manually place the drive shaft into the reduction gearbox in sequence and mesh the gear teeth on the drive shaft with the gear teeth on another drive shaft. Since the bearings and gears of the automotive motor reduction gearbox are relatively large and heavy, combined with repeated mechanized operations on the production line, as the working hours of the operator increase, the tooth surface will be damaged due to fatigue. At the same time, manual operation is also difficult to ensure uniform quality, uniform standards and assembly efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide a gear meshing assembly device to solve the technical problems described in the background technology.

[0004] The gear meshing assembly device includes a frame, on which a first gear frame and a second gear frame are installed. The first gear frame is installed with a first tensioning assembly via a first rotating shaft. The first tensioning assembly is used to extend into a central hollow hole of the first transmission shaft to pick up and fix the first transmission shaft. The second gear frame is installed with a second translational force module. The second translational force module is transmission-connected with a second translation plate. The second tensioning assembly is installed on the second translation plate. The second tensioning assembly is used to extend into the central hollow hole of the second transmission shaft to pick up and fix the second transmission shaft. The second translational force module is used to drive the second translation plate to drive the second transmission shaft on the second tensioning assembly to engage with the first transmission shaft.

[0005] According to the technical solution, the present invention can achieve the following beneficial effects: The present invention extends the first tensioning component into the central hollow hole of the first transmission shaft to pick up and fix the first transmission shaft, and then extends the second tensioning component into the central hollow hole of the second transmission shaft to pick up and fix the second transmission shaft, and then drives the second translation plate to drive the second transmission shaft on the second tensioning component to be in contact with the first transmission shaft through the second translational force module. Since the first tensioning component is installed on the first gear frame through the first rotating shaft, when the second transmission shaft is in contact with the first transmission shaft, the gear on the second transmission shaft will push the gear on the first transmission shaft to rotate until the gear on the second transmission shaft pushes the gear on the first transmission shaft to mesh, and then, the frame can be driven to move horizontally and lift by a conveying mechanism (such as a screw module, a mechanical arm, etc.) to place the second transmission shaft and the first transmission shaft in the reduction box; therefore, the present invention can achieve the meshing and installation of the second transmission shaft and the first transmission shaft through a mechanical mechanism, thereby reducing manual interference and reducing the possibility of tooth surface damage caused by improper manual operation, and at the same time, better ensuring quality uniformity, standard uniformity and assembly efficiency.

[0006] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0007] In some embodiments, the first gear rack is equipped with a first rotating motor that is transmission-connected to the first rotating shaft, and the first rotating motor drives the first tensioning group to drive the first transmission shaft to rotate, so that the second transmission shaft and the first transmission shaft are meshed with each other when they are in contact with each other; According to the technical solution, before or during the contact between the second translational force module and the second translational plate and the second transmission shaft on the second tensioning assembly and the first transmission shaft, the first rotational motor can be used to drive the first tensioning group to rotate the first transmission shaft to adjust the gear tooth position of the first transmission shaft to prevent the gear teeth of the first transmission shaft from rotating with the gear teeth of the second transmission shaft and failing to engage with each other.

[0008] In some embodiments, the second tensioning assembly module is mounted on the second translation plate via a second rotating shaft; According to the technical solution, when the second transmission shaft on the second tensioning assembly is in contact with the first transmission shaft, the gear on the first transmission shaft will push the gear on the second transmission shaft to rotate, so that the gear on the second transmission shaft can mesh with the gear on the first transmission shaft more stably and efficiently.

[0009] In some embodiments, the second gear rack is equipped with a second rotary motor which is transmission-connected to the second rotary shaft, and the second rotary motor drives the second tensioning assembly to drive the second transmission shaft to rotate; According to the technical solution, when the second transmission shaft needs to be rotated to engage with the third transmission shaft, the second rotation motor can be used to drive the second tensioning assembly to drive the second transmission shaft to rotate, so as to adjust the gear tooth position of the second transmission shaft to prevent the gear teeth of the first transmission shaft from rotating with the gear teeth of the second transmission shaft and failing to engage.

[0010] In some embodiments, the first tensioning group or the second tensioning group includes a tensioning sleeve and a tensioning cylinder, the tensioning sleeve is connected to the first gear rack or the second gear rack bearing, the tensioning sleeve is provided with a plurality of tensioning fingers that can freely open outward or move inward, the tensioning cylinder is connected to the bearing of one end of the first rotating shaft or the second rotating shaft, the tensioning cylinder pushes the first rotating shaft or the second rotating shaft to move, and the other end of the first rotating shaft or the second rotating shaft is provided with a tensioning pull head, the outer periphery of the tensioning pull head is inclined, the tensioning pull head is located between the plurality of tensioning fingers and is aligned with the tensioning pull head. The tensioning fingers are close to each other, so that when the plurality of tensioning fingers are inserted into the central hollow hole of the first transmission shaft or the central hollow hole of the second transmission shaft, the tensioning pull head pushes the plurality of tensioning fingers to open outwards and to be interference-connected with the central hollow hole of the first transmission shaft or the central hollow hole of the second transmission shaft. At this time, since the central hollow hole of the first transmission shaft or the central hollow hole of the second transmission shaft restricts the tensioning fingers from opening outwards, the tensioning pull head is interference-connected with the plurality of tensioning fingers, so that the first rotating shaft or the second rotating shaft can drive the tensioning fingers and the first transmission shaft and the second transmission shaft to rotate; According to the technical solution, the present invention can further achieve the following beneficial effects: 1. Since the second transmission shaft and the first transmission shaft are grabbed and driven to rotate by inserting into the central hollow hole of the first transmission shaft or the central hollow hole of the second transmission shaft, when the peripheral gear teeth of the second transmission shaft mesh with the peripheral gear teeth of the first transmission shaft, no interference or obstruction is caused; 2. Compared with the traditional clamping jaws that clamp the outer periphery of the first transmission shaft and the second transmission shaft, during the process of the outer peripheral gear teeth of the second transmission shaft rotating and meshing with the outer peripheral gear teeth of the first transmission shaft, the fixing parts used to fix the first transmission shaft and the second transmission shaft will not collide, thereby improving the safety during meshing. In addition, there is no need to control the rotation stroke of the first transmission shaft and the second transmission shaft to make the above-mentioned fixing parts staggered to avoid, thereby improving the meshing efficiency.

[0011] In some embodiments, the frame is installed with a third gear frame, the third gear frame is installed with a third transverse force module, the third transverse force module is transmission-connected with a third transverse plate, the third transverse plate is installed with a clamping assembly for clamping a portion of the third transmission shaft, and the third transverse force module drives the third transverse plate to drive the third transmission shaft on the clamping assembly to engage with the first transmission shaft or the first transmission shaft; According to the technical solution, the present invention can further achieve the following beneficial effects: 1. When three transmission shafts need to be assembled, the third transmission shaft is clamped by the clamping assembly. After that, the moving force module drives the third transverse plate to drive the third transmission shaft on the clamping assembly to contact the first transmission shaft or the first transmission shaft. At this time, since the first transmission shaft and the second transmission shaft are rotatable, the third transmission shaft will push the first transmission shaft or the second transmission shaft to rotate at the moment of contact with the first transmission shaft or the second transmission shaft, so that the gear teeth of the third transmission shaft can be meshed with the gear teeth of the first transmission shaft or the second transmission shaft; 2. Since the first tensioning assembly is inserted into the central hollow hole of the first transmission shaft, or the second tensioning assembly is inserted into the central hollow hole of the second transmission shaft, even if the clamping assembly can clamp the third transmission shaft by clamping a part of the third transmission shaft and drive it to fit with the first transmission shaft or the second transmission shaft, the meshing of the gear teeth will not be affected; 3. Since the third transmission shaft is clamped by clamping, the lighter transmission shaft can be grasped by the first tensioning assembly and the second tensioning assembly, while the heavier and larger transmission shaft can be grasped by the clamping assembly, thereby improving the assembly stability of the transmission shaft.

[0012] In some embodiments, the clamping assembly includes a clamping claw cylinder, which drives a gripper that can move closer or open to each other, and the gripper is used to clamp the outer periphery of the third transmission shaft. When the gripper clamps the third transmission shaft, part of the third transmission shaft is exposed outward, and the outwardly exposed part of the third transmission shaft is used to engage with the first transmission shaft or the second transmission shaft; According to the technical solution, the present invention can further achieve the following beneficial effects: 1. The gripper is driven to move closer by the gripper cylinder, so as to clamp the outer periphery of the third transmission shaft; 2. When the gripper clamps the third transmission shaft, part of the third transmission shaft is exposed outward, so that the clamped third transmission shaft can mesh with the gear teeth of the first transmission shaft or the gear teeth of the second transmission shaft of the first transmission shaft through the exposed part.

[0013] In some embodiments, the clamp assembly bearing is connected to the third transverse plate; According to the technical solution, when the third transmission shaft contacts the first transmission shaft or the first transmission shaft, the first transmission shaft or the first transmission shaft can push the third transmission shaft to rotate, so that the third transmission shaft can engage with the first transmission shaft or the first transmission shaft more stably.

[0014] In some embodiments, a guide shaft is provided between the grippers, and the guide shaft is used to be inserted into the central hollow hole of the third transmission shaft to position the third transmission shaft; According to the technical solution, when the gripper moves to the periphery of the guide shaft, it can be inserted into the central hollow hole of the third transmission shaft together with the guide shaft to position the third transmission shaft, so that when the gripper is driven by the clamping cylinder to move closer, the third transmission shaft can be stably clamped. At the same time, when the third transverse moving force module drives the third transverse moving plate to drive the third transmission shaft on the clamping assembly to stick to the first transmission shaft or the first transmission shaft, the third transmission shaft can be more stably engaged with the first transmission shaft or the first transmission shaft.

[0015] In some embodiments, the frame is installed with a gear tooth sensor; according to the technical solution, the gear teeth of the first transmission shaft, the gear teeth of the second transmission shaft, and the gear teeth of the third transmission shaft can be positioned by the gear tooth sensor, thereby adjusting the positions of the gear teeth of the first transmission shaft, the gear teeth of the second transmission shaft, and the gear teeth of the third transmission shaft, so that the gear teeth of the first transmission shaft, the gear teeth of the second transmission shaft, and the gear teeth of the third transmission shaft can be more stably engaged.

[0019] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail with reference to the accompanying drawings. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0020] like Figures 1 to 7 As shown, the present specific embodiment provides a gear meshing assembly device, which includes a frame 1, on which a first gear frame 2 and a second gear frame 3 are installed, the first gear frame 2 is installed with a first tensioning component 22 through a first rotating shaft 21, the first tensioning component 22 is used to extend into the central hollow hole of the first transmission shaft to pick up and fix the first transmission shaft, the second gear frame 3 is installed with a second translational force module 31, the second translational force module 31 is transmission-connected with a second translation plate 32, the second tensioning component 33 is installed on the second translation plate 32, the second tensioning component 33 is used to extend into the central hollow hole of the second transmission shaft to pick up and fix the second transmission shaft, the second translational force module 31 is used to drive the second translation plate 32 to drive the second transmission shaft on the second tensioning component 33 to engage with the first transmission shaft.

[0021] The gear meshing assembly device extends into the central hollow hole of the first transmission shaft through the first tensioning component 22 to pick up and fix the first transmission shaft. Thereafter, the second tensioning component 33 extends into the central hollow hole of the second transmission shaft to pick up and fix the second transmission shaft. Thereafter, the second translation plate 32 is driven by the second translation force module 31 to drive the second transmission shaft on the second tensioning component 33 to be in contact with the first transmission shaft. Since the first tensioning component 22 is installed on the first gear frame 2 through the first rotating shaft 21, when the second transmission shaft is in contact with the first transmission shaft, The gear on the first transmission shaft will push the gear on the first transmission shaft to rotate until the gear on the second transmission shaft pushes the gear on the first transmission shaft to engage. Subsequently, the frame 1 can be driven to move horizontally and lift up and down through a handling mechanism (such as a screw module, a robotic arm, etc.) to place the second transmission shaft and the first transmission shaft in the reduction box; therefore, the present invention can achieve the engagement and installation of the second transmission shaft and the first transmission shaft through a mechanical mechanism, thereby reducing manual interference and the possibility of damaging the tooth surface due to improper manual operation, and at the same time, better ensuring quality uniformity, standard uniformity and assembly efficiency.

[0022] In some embodiments, the first gear rack 2 is equipped with a first rotating motor 23 which is transmission-connected to the first rotating shaft 21. The first rotating motor 23 drives the first tensioning group to rotate the first transmission shaft so that the second transmission shaft meshes with the first transmission shaft when they are in contact with each other.

[0023] Before or during the process of the second translational force module 31 driving the second translational plate 32 to drive the second transmission shaft on the second tensioning assembly 33 to contact the first transmission shaft, the first rotation motor 23 drives the first tensioning assembly to rotate the first transmission shaft to adjust the gear tooth position of the first transmission shaft to prevent the gear teeth of the first transmission shaft from rotating with the gear teeth of the second transmission shaft and failing to engage with each other.

[0024] In some embodiments, the second tensioning assembly 33 module is installed on the second translation plate 32 via a second rotating shaft 34 .

[0025] When the second transmission shaft on the second tensioning assembly 33 is in contact with the first transmission shaft, the gear on the first transmission shaft will push the gear on the second transmission shaft to rotate, so that the gear on the second transmission shaft can mesh with the gear on the first transmission shaft more stably and efficiently.

[0026] In some embodiments, the second gear rack 3 is equipped with a second rotary motor 35 which is transmission-connected to the second rotary shaft 34 . The second rotary motor 35 drives the second tensioning assembly 33 to drive the second transmission shaft to rotate.

[0027] When the second transmission shaft needs to be rotated to engage with the third transmission shaft, the second tensioning assembly 33 can be driven by the second rotating motor 35 to rotate the second transmission shaft to adjust the gear position of the second transmission shaft to prevent the gear teeth of the first transmission shaft from rotating and failing to engage with the gear teeth of the second transmission shaft.

[0028] In some embodiments, the first tensioning group or the second tensioning group includes a tensioning sleeve 41 and a tensioning cylinder 42. The tensioning sleeve 41 is connected to the first gear frame 2 or the second gear frame 3 by a bearing. The tensioning sleeve 41 is provided with a plurality of tensioning fingers 43 that can be freely opened outward or moved inward. The tensioning cylinder 42 is connected to one end of the first rotating shaft 21 or one end of the second rotating shaft 34 by a bearing. The tensioning cylinder 42 pushes one end of the first rotating shaft 21 or one end of the second rotating shaft 34 to move. The other end of the first rotating shaft 21 or the other end of the second rotating shaft 34 is provided with a tensioning pull head 44. The outer periphery of the tensioning pull head 44 is inclined. The tensioning pull head 44 is located at a plurality of tensioning fingers. The tensioning fingers 43 are between the tensioning fingers 43 and are in contact with the tensioning fingers 43, so that when the tensioning fingers 43 are inserted into the central hollow hole of the first transmission shaft or the central hollow hole of the second transmission shaft, the tensioning pull head 44 pushes the tensioning fingers 43 to open outward and are interference-connected with the central hollow hole of the first transmission shaft or the central hollow hole of the second transmission shaft. At this time, since the central hollow hole of the first transmission shaft or the central hollow hole of the second transmission shaft restricts the tensioning fingers 43 from opening outward, the tensioning pull head 44 is interference-connected with the tensioning fingers 43, so that the first rotating shaft 21 or the second rotating shaft 34 can drive the tensioning fingers 43 and the first transmission shaft and the second transmission shaft to rotate.

[0029] Since the second transmission shaft and the first transmission shaft are grabbed and driven to rotate by inserting into the central hollow hole of the first transmission shaft or the central hollow hole of the second transmission shaft, when the peripheral gear teeth of the second transmission shaft are engaged with the peripheral gear teeth of the first transmission shaft, no interference or obstruction is caused.

[0030] Compared with the traditional clamping jaws that clamp the outer periphery of the first transmission shaft and the second transmission shaft, during the process of rotational meshing of the outer peripheral gear teeth of the second transmission shaft with the outer peripheral gear teeth of the first transmission shaft, the fixing components used to fix the first transmission shaft and the second transmission shaft will not collide, thereby improving the safety during meshing. In addition, there is no need to control the rotation stroke of the first transmission shaft and the second transmission shaft to make the above-mentioned fixing components misaligned and avoid, thereby improving the meshing efficiency.

[0031] In some embodiments, the frame 1 is installed with a third gear rack 5, the third gear rack 5 is installed with a third transverse moving force module 51, the third transverse moving force module 51 is transmission-connected with a third transverse moving plate 52, the third transverse moving plate 52 is installed with a clamping assembly 6 for clamping a part of the third transmission shaft, the third transverse moving force module 51 drives the third transverse moving plate 52 to drive the third transmission shaft on the clamping assembly 6 to engage with the first transmission shaft or the first transmission shaft.

[0032] When three transmission shafts need to be assembled, the third transmission shaft is clamped by the clamping assembly 6. Thereafter, the moving force module drives the third transverse plate 52 to drive the third transmission shaft on the clamping assembly 6 to be attached to the first transmission shaft or the first transmission shaft. At this time, since the first transmission shaft and the second transmission shaft are rotatable, the moment the third transmission shaft contacts the first transmission shaft or the second transmission shaft, the third transmission shaft will push the first transmission shaft or the second transmission shaft to rotate, so that the gear teeth of the third transmission shaft can be engaged with the gear teeth of the first transmission shaft or the second transmission shaft.

[0033] Since the first tensioning component 22 extends into the central hollow hole of the first transmission shaft, or the second tensioning component 33 extends into the central hollow hole of the second transmission shaft), even if the clamping component 6 can clamp the third transmission shaft by clamping a part of the third transmission shaft and drive it to fit against the first transmission shaft or the second transmission shaft, it will not affect the meshing of the gear teeth; in addition, since the third transmission shaft is clamped by clamping, the lighter transmission shaft can be grasped by the first tensioning component 22 and the second tensioning component 33, while the heavier and larger transmission shaft can be grasped by the clamping component 6, thereby improving the assembly stability of the transmission shaft.

[0034] In some embodiments, the clamping assembly 6 includes a clamping cylinder 61, which drives a gripper 62 that can move closer or open to each other. The gripper 62 is used to clamp the outer periphery of the third transmission shaft. When the gripper 62 clamps the third transmission shaft, part of the third transmission shaft is exposed outwardly, and the outwardly exposed part of the third transmission shaft is used to engage with the first transmission shaft or the second transmission shaft.

[0035] The clamping claw cylinder 61 drives the gripper 62 to move closer, thereby clamping the outer periphery of the third transmission shaft.

[0036] When the gripper 62 clamps the third transmission shaft, part of the third transmission shaft is exposed outwardly, so that the clamped third transmission shaft can mesh with the gear teeth of the first transmission shaft or the gear teeth of the first transmission shaft and the second transmission shaft through the exposed part.

[0037] In some embodiments, the clamping assembly 6 is bearing-connected to the third transverse plate 52. When the third transmission shaft contacts the first transmission shaft or the first transmission shaft, the first transmission shaft or the first transmission shaft can push the third transmission shaft to rotate, so that the third transmission shaft can be more stably engaged with the first transmission shaft or the first transmission shaft.

[0038] In some embodiments, a guide shaft 63 is provided between the grippers 62 , and the guide shaft 63 is used to be inserted into the central hollow hole of the third transmission shaft to position the third transmission shaft.

[0039] When the gripper 62 moves to the periphery of the guide shaft 63, it can be inserted into the central hollow hole of the third transmission shaft together with the guide shaft 63 to position the third transmission shaft, so that when the clamping cylinder 61 drives the gripper 62 to move closer, the third transmission shaft can be stably clamped. At the same time, when the third transverse moving force module 51 drives the third transverse moving plate 52 to drive the third transmission shaft on the clamping assembly 6 to stick to the first transmission shaft or the first transmission shaft, the third transmission shaft can be more stably engaged with the first transmission shaft or the first transmission shaft.

[0040] In some embodiments, the frame 1 is equipped with a gear tooth sensor 7, which can be an infrared sensor. The infrared sensor emits infrared light through the outer periphery of the first transmission shaft, the second transmission shaft and the third transmission shaft, and determines the gear tooth position according to whether the infrared light is blocked by the gear teeth or the infrared light can pass through the tooth grooves and pass through the first transmission shaft, the second transmission shaft and the third transmission shaft.

[0041] Therefore, the gear teeth of the first transmission shaft, the gear teeth of the second transmission shaft and the gear teeth of the third transmission shaft can be positioned by the gear tooth sensor 7, thereby driving the first transmission shaft and the second transmission shaft to rotate, and adjusting the relative positions of the gear teeth of the first transmission shaft, the gear teeth of the second transmission shaft and the third transmission shaft, so that the gear teeth of the first transmission shaft, the gear teeth of the second transmission shaft and the third transmission shaft can mesh more stably.

[0042] Furthermore, in order to facilitate the assembly of the first transmission shaft, the second transmission shaft and the third transmission shaft, the first transmission shaft, the second transmission shaft and the third transmission shaft may be provided with a central hollow hole in the central area.

[0043] In order to further illustrate the gear meshing assembly device described in this specific embodiment, the following examples are listed.

[0044] like Figures 1 to 7As shown, this embodiment provides a gear meshing assembly device, which includes a frame 1, and the frame 1 is used to install a robotic arm or other driving device that can drive its lateral, longitudinal and lifting movements. In addition, the frame 1 is installed with a first gear frame 2, a second gear frame 3, a third gear frame 5 and a gear tooth sensor 7.

[0045] The first gear frame 2 is equipped with a first tensioning assembly 22 and a first rotating motor 23. The first tensioning assembly 22 is installed on the first gear frame 2 through the first rotating shaft 21. The first tensioning assembly 22 is used to extend into the central hollow hole of the first transmission shaft to pick up and fix the first transmission shaft. The first rotating motor 23 drives the first tensioning assembly to drive the first transmission shaft to rotate.

[0046] The second gear rack 3 is equipped with a second translation force module 31 and a second rotary motor 35. The second translation force module 31 is connected to the second translation plate 32 in transmission, and the second tensioning assembly 33 is installed on the second translation plate 32 through the second rotary shaft 34. The second tensioning assembly 33 is used to extend into the central hollow hole of the second transmission shaft to pick up and fix the second transmission shaft. The second translation force module 31 is used to drive the second translation plate 32 to drive the second transmission shaft on the second tensioning assembly 33 to engage with the first transmission shaft. The second rotary motor 35 is connected to the second rotary shaft 34 in transmission, and the second rotary motor 35 drives the second tensioning assembly 33 to rotate the second transmission shaft.

[0047] The first tensioning group or the second tensioning group includes a tensioning sleeve 41 and a tensioning cylinder 42. The tensioning sleeve 41 is connected to the first gear frame 2 or the second gear frame 3 through the first rotating shaft 21 or the second rotating shaft 34. The tensioning sleeve 41 is provided with a plurality of tensioning fingers 43 that can be freely opened outward or moved inward. The tensioning cylinder 42 is connected to one end of the first rotating shaft 21 or one end of the second rotating shaft 34. The tensioning cylinder 42 pushes one end of the first rotating shaft 21 or one end of the second rotating shaft 34 to move. The other end of the first rotating shaft 21 or the other end of the second rotating shaft 34 is provided with a tensioning pull head 44. The outer periphery of the tensioning pull head 44 is inclined. The tensioning pull head 44 is located at The tensioning fingers 43 are arranged between the tensioning fingers 43 and in contact with the tensioning fingers 43, so that when the tensioning fingers 43 are inserted into the central hollow hole of the first transmission shaft or the central hollow hole of the second transmission shaft, the tensioning pull head 44 pushes the tensioning fingers 43 to open outward and to be interference-connected with the central hollow hole of the first transmission shaft or the central hollow hole of the second transmission shaft. At this time, since the central hollow hole of the first transmission shaft or the central hollow hole of the second transmission shaft restricts the tensioning fingers 43 from opening outward, the tensioning pull head 44 is interference-connected with the tensioning fingers 43, so that the first rotating shaft 21 or the second rotating shaft 34 can drive the tensioning fingers 43 and the first transmission shaft and the second transmission shaft to rotate.

[0048] The third gear rack 5 is equipped with a third transverse moving force module 51, and the third transverse moving force module 51 is transmission-connected to the third transverse moving plate 52. The third transverse moving plate 52 is equipped with a bearing connected to a clamping assembly 6, and the clamping assembly 6 is used to clamp a part of the third transmission shaft. The third transverse moving force module 51 drives the third transverse moving plate 52 to drive the third transmission shaft on the clamping assembly 6 to engage with the first transmission shaft or the first transmission shaft.

[0049] The clamping assembly 6 includes a clamping claw cylinder 61, which drives a gripper 62 that can be brought together or opened. The gripper 62 is used to clamp the outer periphery of the third transmission shaft. When the gripper 62 clamps the third transmission shaft, part of the third transmission shaft is exposed outward, and the outwardly exposed part of the third transmission shaft is used to engage with the first transmission shaft or the second transmission shaft. A guide shaft 63 is provided between the grippers 62, and the guide shaft 63 is used to be inserted into the central hollow hole of the third transmission shaft to position the third transmission shaft.

[0050] The gear tooth sensor 7 may be an infrared sensor, which emits infrared light through the outer periphery of the first transmission shaft, the second transmission shaft and the third transmission shaft, and determines the gear tooth position according to whether the infrared light is blocked by the gear teeth or the infrared light can pass through the tooth grooves and pass through the first transmission shaft, the second transmission shaft and the third transmission shaft.

[0051] The following is a working description of the gear meshing assembly device.

[0052] The first tensioning component 22 extends into the central hollow hole of the first transmission shaft to fix the first transmission shaft, the second tensioning component 33 extends into the central hollow hole of the second transmission shaft to fix the second transmission shaft, and the clamping component 6 clamps the third transmission shaft; thereafter, the robotic arm drives the frame 1 to rise, so that the first transmission shaft, the second transmission shaft and the third transmission shaft rise, so that they can move and rotate freely; thereafter, the second rotating motor 35 drives the second tensioning component 33 to drive the second transmission shaft to rotate, and the second translational force module 31 drives the second translation plate 32 to drive the second transmission shaft on the second tensioning component 33 to fit with the first transmission shaft. At this time, the gear on the second transmission shaft will push the gear on the first transmission shaft to rotate until the gear on the second transmission shaft pushes the gear on the first transmission shaft to engage; thereafter, the second rotating motor 35 drives the second tensioning component 33 to drive the second transmission shaft to rotate, and the second transmission shaft The shaft drives the first transmission shaft to rotate, or the first rotating motor 23 drives the first tensioning group to drive the first transmission shaft to rotate, and the first transmission shaft drives the second transmission shaft to rotate.
