[0047] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0048] The embodiment of the present application provides an automatic joint tightening device, including a fixing mechanism 1, a clamping mechanism 4, a moving mechanism 6, and a screwing mechanism 5. Please refer to Figure 1 .

[0049] The fixing mechanism 1 is used to fix the device 2, and the device 2 needs to wait for the installation of the connector 3. Here, the device 2 and the fixing mechanism 1 are detachably connected. After the installation of the connector 3 of a certain device 2 is completed, the device 2 can be removed to wait for subsequent use. The specific detachable connection method can be a snap connection, a fastener 14 connection, etc., which can facilitate installation and disassembly while ensuring reliable and stable fixation.

[0050] The device 2 on which the joint 3 is to be installed may be in the form of a pipeline, a water collector, etc., and may be any device 2 on which the joint 3 needs to be installed.

[0051] The fixing mechanism 1 is specifically applicable to the setting of different types of devices 2, based on the detachable connection between the fixing mechanism 1 and the device 2. Even for different types of devices 2, it is sufficient as long as the device 2 and the fixing mechanism 1 can be fastened by the fastener 14.

[0052] The clamping mechanism 4 is provided with a plurality of clamping cavities 41 arranged along the moving route of the fixing mechanism 1. The clamping cavities 41 can clamp the fixing mechanism 1, that is, can relatively fix the fixing mechanism 1 so as to relatively fix the device 2 on the fixing mechanism 1.

[0053] The mobile mechanism 6 is connected to the fixed mechanism 1, and the fixed mechanism 1 can be driven to move by the mobile mechanism 6. The mobile mechanism 6 can specifically be made of a cylinder, an oil cylinder, an electric cylinder, a gear rack assembly and a motor, a linear module, a robotic arm, etc. that can realize linear motion, and can be flexibly set according to actual movement needs.

[0054] The fixing mechanism 1 can be moved out of any clamping cavity 41 and moved into the adjacent clamping cavity 41, that is, the moving route of the fixing mechanism 1 is in two directions, one is the direction of moving in and out relative to the clamping cavity 41, and the other is the direction corresponding to the movement along the two adjacent clamping cavities 41. Correspondingly, the driving that the moving mechanism 6 can provide is also at least in two directions to meet the use requirements.

[0055] The screwing mechanism 5 is arranged on the moving route of the fixing mechanism 1, so that the movement of the fixing mechanism 1 can deliver the device 2 and the joint 3 to the working position of the screwing mechanism 5, and further by the screwing mechanism 5 moving and approaching the joint 3, a joint 3 delivered by the fixing mechanism 1 can be screwed onto the device 2, and then the screwing mechanism 5 removes the contact with this joint 3; the moving mechanism 6 moves the fixing mechanism 1 from the state where the previous joint 3 is clamped in the clamping cavity 41 to another clamping cavity 41, so that the next joint 3 can reach the working position, and by the screwing mechanism 5 moving and approaching the joint 3 again, the next joint 3 can be screwed onto the device 2, and it is repeated until all the joints 3 on the device 2 are screwed.

[0056] In this embodiment, it should be noted that the connector 3 can be pre-installed on the device 2. This installation is not a tight installation, but only to keep the connector 3 on the device 2 to prevent it from falling, so as to facilitate the subsequent tightening operation. For example, the connector 3 is installed on the device 2 by manually screwing it a few turns, and then tightened one by one by the screwing mechanism 5.

[0057] In this embodiment, the screwing mechanism 5 has a movement that can move closer to or away from the connector 3, and also has a movement that can rotate to tighten the connector 3. After tightening the connector 3, only relying on the movement of the screwing mechanism 5 away from the connector 3 can relatively separate the connector 3 and the screwing mechanism 5.

[0058] In this embodiment, the clamping cavity 41 can be a closed cavity or a cavity with an opening. Specifically, when the clamping cavity 41 is a closed cavity, such as a circular shape, the moving mechanism 6 can drive the fixing mechanism 1 to move out or retract. Here, the extension corresponds to the situation where the fixing mechanism 1 is relatively fixed in the clamping cavity 41, and the retraction corresponds to the situation where the fixing mechanism 1 is relatively moved out of the clamping cavity 41 and can move into the next clamping cavity 41. When the clamping cavity 41 is a cavity with an opening, such as a U shape, the moving mechanism 6 can drive the fixing mechanism 1 to move to disengage from the opening of the clamping cavity 41 or enter the clamping cavity 41 from the opening. Here, disengaging from the clamping cavity 41 corresponds to the situation where the fixing mechanism 1 can move into the next clamping cavity 41, and entering the clamping cavity 41 from the opening corresponds to the situation where the fixing mechanism 1 moves to be relatively fixed in the clamping cavity 41.

[0059] In this embodiment, since the tightening of several connectors 3 on the device 2 relies on the movement and transportation of the moving mechanism 6 and the automatic and unified tightening of the screwing mechanism 5, good tightening reliability can be ensured, saving time and effort, and improving the installation efficiency of the connector 3.

[0060] On the basis of the above embodiment, please refer to Figure 1 、 Figure 3 , the clamping cavity 41 includes a clamping section 411 and a disengaging section 412 communicating therewith. The disengaging section 412 extends in a direction away from the clamping section 411 to guide the fixing mechanism 1 to move into or out of the clamping section 411.

[0061] In this embodiment, the clamping section 411 is the part that can reliably clamp the fixing mechanism 1, and can relatively fix the fixing mechanism 1 in the clamping mechanism 4 to wait for the subsequent operation of screwing the connector 3; the disengaging section 412 is used for guiding the fixing mechanism 1 to enter or exit the clamping section 411, and can ensure the smooth transfer of the fixing mechanism 1 between adjacent clamping cavities 41, and ensure the reliable tightening of several connectors 3 on the device 2.

[0062] In this embodiment, through the guidance of the disengaging section 412, the movement of the fixing mechanism 1 in and out can be facilitated, and damage to components or the clamping cavity 41 can be avoided. The disengaging section 412 can be specifically set as an inclined-plane guide or an arc-plane guide, which can provide a reliable guiding effect.

[0063] In addition, the side of the inclined-plane guide or the arc-plane guide away from the clamping section 411 can have an opening or can be closed. For example, an opening is provided on the side of the inclined-plane guide or the arc-plane guide away from the clamping section 411. This opening enables the part of the fixing mechanism 1 corresponding to the clamping cavity 41 to smoothly enter the clamping section 411 under the action of the inclined-plane guide or the arc-plane guide, and also enables the fixing mechanism 1 to smoothly move out of the clamping cavity 41 through this opening under the action of the inclined-plane guide or the arc-plane guide.

[0064] If the side of the inclined-plane guide or the arc-plane guide away from the clamping section 411 is closed, it means that the fixing mechanism 1 can disengage from the disengaging section 412 before reaching the closed position, and the fixing mechanism 1 does not enter the clamping section 411 from the closed position of the disengaging section 412. Therefore, it is not restricted by the closed section of the disengaging section 412. In this case, the overall structural strength and hardness of the clamping cavity 41 can be ensured.

[0065] In this embodiment, the disengaging section 412 extends in a direction gradually away from the clamping section 411. It should be noted here that the extending direction can also be regarded as the direction away from the device 2. The clamping section 411 is relatively close to the device 2, and the disengaging section 412 is relatively far from the device 2, so as to provide a reliable guide for the movement of the device 2 in and out through the disengaging section 412 without affecting the movement process of the device 2 along with the moving mechanism 6.

[0066] Based on any of the above embodiments, please refer to Figure 3 The disengaging section 412 is inclined with respect to the clamping section 411, and an opening is provided on the side of the disengaging section 412 away from the clamping section 411.

[0067] As Figure 3 shown, the disengaging section 412 is formed by an inclined plate that is bent with respect to the clamping section 411. This inclined plate can be formed by bending or can be connected to the disengaging section 412 by welding, and has a certain structural strength and hardness.

[0068] The clamping cavity 41 formed by the disengaging section 412 and the clamping section 411 can facilitate the movement of the fixing mechanism 1 into any clamping cavity 41 and can also facilitate the smooth disengagement of the fixing mechanism 1 from any clamping cavity 41, so as to meet the requirement of sending several connectors 3 of the device 2 to the working positions of the screwing mechanism 5 through the movement of the fixing mechanism 1 for screwing one by one, making the screwing of the connectors 3 on the device 2 automated and improving the installation efficiency and reliability of the connectors 3.

[0069] TakingFigure 1 For example, when the fixing mechanism 1 disengages from the clamping cavity 41, it moves from bottom to top, making the whole fixing mechanism 1 higher than the surface of the disengaging section 412, so that under the drive of the left-to-right movement, the fixing mechanism 1 can be driven to move above the adjacent clamping cavity 41, and then the fixing mechanism 1 moves from top to bottom, so that the fixing mechanism 1 is relatively fixed in the clamping section 411 of the adjacent clamping cavity 41.

[0070] Based on any of the above embodiments, please refer to Figure 3 , the clamping mechanism 4 includes at least two side plates 42 arranged oppositely, a moving space 43 is formed between any two adjacent side plates 42, and the fixing mechanism 1 can move in the moving space 43. The side plates 42 have a certain thickness, have good structural strength, and can have certain anti-impact and anti-deformation properties to ensure reliable working performance.

[0071] The moving space 43 between any two adjacent side plates 42 is the space that can be used for the fixing mechanism 1 to move in different directions. The fixing mechanism 1 is restricted to move in the moving space 43 for a certain limit.

[0072] Each side plate 42 is provided with a clamping cavity 41. The clamping cavities 41 located on the same side of at least two side plates 42 can act together to clamp the fixing mechanism 1. The same side is the side perpendicular to the moving direction of the fixing mechanism 1 relative to the same clamping cavity 41. Through the setting of multiple clamping cavities 41, reliable clamping of the fixing mechanism 1 can be ensured, the reliable stability of the fixing mechanism 1 when sending the device 2 to the working position of the screwing mechanism 5 can be ensured, and the reliable screwing operation of the joint 3 can be ensured.

[0073] In this embodiment, through the setting of at least two side plates 42, the number of side plates 42 can be increased or decreased according to the actual situation to meet different usage requirements. For example, if the overall size of the device 2 is relatively large and the redundant side plates 42 will cause interference, the redundant part can be removed; if the part of the fixing mechanism 1 corresponding to the clamping cavity 41 is relatively large and multiple clamping cavities 41 need to act together to clamp reliably, the number of side plates 42 can be increased.

[0074] Such as Figure 3 As shown in the figure, when two side plates 42 are provided, the disengaging sections 412 in both side plates 42 are arranged away from the moving space 43 to maintain good symmetry and ensure structural strength.

[0075] Based on any of the above embodiments, the moving mechanism 6 includes a first moving component and a second moving component. The first moving component can drive the fixing mechanism 1 to move in a first direction, so that the fixing mechanism 1 can be moved into or out of the clamping cavity 41. The second moving component is connected to the first moving component to realize the movement of the fixing mechanism 1 in a second direction, so that the fixing mechanism 1 can move between two adjacent clamping cavities 41. The first direction is set perpendicular to the second direction, so as to Figure 1 take an example, the first direction is the up-and-down movement, and the second direction is the left-and-right movement.

[0076] The distance of a single movement of the second moving component is a multiple of the distance between two adjacent clamping cavities 41. Here, the multiple can be one time, two times or more. Among them, based on the types of the connectors 3 on the device 2, they may be the same or different. Here, it mainly refers to that there are certain differences in the outer diameter sizes of the connectors 3. For example, in the distribution form of large-size connectors - small-size connectors - large-size connectors - small-size connectors, the second moving component can first drive the large-size connector to move to the working position of the screwing mechanism 5 for screwing. In this case, the distance of a single movement of the corresponding second moving component is twice the distance between the adjacent clamping cavities 41. Of course, the second moving component can also drive the large-size connector to move to the working position of the screwing mechanism 5 for screwing, and then drive the adjacent small-size connector to move to the working position of the screwing mechanism 5 for screwing, and only then perform the screwing of the next large-size connector, and so on.

[0077] It should be noted that for connectors 3 with different outer diameter sizes, the equipped screwing mechanism 5 can also have screwing parts of various sizes. For example, by setting multiple sets of screwing parts, the corresponding required size can be selected according to the actual situation.

[0078] Based on any of the above embodiments, please refer to Figure 6 、 Figure 7 , the first moving component includes a bearing plate 66 and a fixing plate 62. One side of the bearing plate 66 is provided with a bearing surface for bearing the fixing mechanism 1. The other side of the bearing plate 66 is provided with a plurality of lifting cylinders 65. The moving ends of the lifting cylinders 65 are fixed to the bearing plate 66, and the fixed ends of the lifting cylinders 65 are connected to the fixing plate 62. The fixing plate 62 is connected to the second moving component. The bearing surface is the part for placing the fixing mechanism 1 and the device 2. The positioning part can be set on the bearing surface to ensure the reliable stability of the fixing mechanism 1 on the bearing surface, so that the device 2 can reliably move in the first direction along with the driving of the first moving component along with the fixing mechanism 1.

[0079] The driving of the first moving component mainly depends on the lifting cylinder 65. The fixed end of the lifting cylinder 65 is connected to the second moving component through the fixing plate 62, so that the second moving component can drive the whole first moving component, the fixing mechanism 1 and the device 2 to generate the movement in the second direction.

[0080] When the lifting cylinder 65 is in the lifted state, it can move the fixing mechanism 1 and the device 2 upward, so that the fixing mechanism 1 disengages from the clamping cavity 41, and can be driven by the second moving component to send the fixing mechanism 1 and the device 2 to the corresponding position of another adjacent clamping cavity 41; when the lifting cylinder 65 is in the reset and lowered state, it can move the fixing mechanism 1 and the device 2 downward, so that the fixing mechanism 1 enters another adjacent clamping cavity 41, completing the movement of the device 2 in the second direction and the first direction, so as to be able to send the connectors 3 at different positions on the device 2 to the working position of the screwing mechanism 5 in sequence for screwing operations.

[0081] In this embodiment, the number of the lifting cylinders 65 is not limited. For example, in order to maintain good stability, a plurality of lifting cylinders 65 can be arranged in the second direction between the bearing plate 66 and the fixing plate 62, and can be flexibly selected and designed according to the actual situation.

[0082] Please refer to Figure 6 、 Figure 7 The second moving component includes a moving cylinder 61 provided on the fixing frame 7. The moving end of the moving cylinder 61 is connected to the fixing plate 62, so as to be able to drive the first moving component, the fixing mechanism 1 and the device 2 to move in the second direction through the fixing plate 62.

[0083] In this embodiment, on the premise of using the moving cylinder 61, the fixing mechanism 1 can be fixed on the bearing plate 66 or just placed on the bearing plate 66.

[0084] In a specific implementation manner, if the stroke of the moving cylinder 61 can meet the installation of the connectors 3 with the farthest spacing distance on the device 2, the fixing mechanism 1 can be fixed on the bearing plate 66. During the screwing operation, the bearing plate 66 can play a certain supporting role for the fixing mechanism 1. When the moving cylinder 61 extends or retracts in one direction, it can realize sending the multiple connectors 3 on the device 2 to the working positions of the screwing mechanism 5 respectively for separate screwing operations.

[0085] In another specific embodiment, if the stroke of the moving cylinder 61 cannot meet the installation of the connectors 3 with the farthest spacing on the device 2, the fixing mechanism 1 can be placed on the bearing plate 66. Here, "placed" does not simply mean putting it there; there is a certain positioning, but it is not a clamping relationship, only ensuring the reliable stability of the fixing mechanism 1 placed on the bearing plate 66. In this case, when the moving cylinder 61 extends and drives the fixing mechanism 1 to move a certain distance in the second direction, and then the lifting cylinder 65 drops and resets to clamp the fixing mechanism 1 in the clamping cavity 41, the fixing mechanism 1 has already been supported by the clamping cavity 41. The moving cylinder 61 can retract and drive the first moving component to move in the reverse direction by a certain distance to reset the moving cylinder 61. If it is necessary to transfer the fixing structure to another clamping cavity 41 again, the moving cylinder 61 can perform the extending and retracting actions again. The certain distances of extension and retraction all correspond to multiples of the distance between adjacent clamping cavities 41, and the spacing is relatively small. Through this setting form, the small-distance movement of the moving cylinder 61 can meet the situation where multiple connectors 3 need to be installed on the device 2, resulting in a longer moving stroke distance, with fewer requirements for the moving cylinder 61 and reduced usage costs.

[0086] At least one section of guide rail 63 is provided on the fixing frame 7. On one side of the fixing plate 62 close to the guide rail 63, a sliding member 64 or a rolling member is provided. The sliding member 64 or the rolling member is connected to the guide rail 63 to achieve the guiding of the moving cylinder 61 driving the fixing plate 62 to move. The setting of the guide rail 63 here can ensure that the single moving stroke of the moving cylinder 61 is the distance between adjacent two clamping cavities 41, ensuring the accuracy of the moving route and the reliability of the sequential installation and screwing of multiple connectors 3. If multiple sections of guide rail 63 are provided, they can be arranged in multiple sections in the third direction perpendicular to the second direction and the first direction to ensure the reliable stability of the guiding.

[0087] The settings of the sliding member 64 and the rolling member can cooperate with the slide rail for guiding. There are no excessive restrictions on the quantity and form.

[0088] A guiding section is provided on the fixing frame 7 corresponding to the area of the lifting cylinder 65. The distance between the head end and the tail end of the guiding section corresponds to the positions of the extension and retraction of the moving cylinder 61, and corresponds to multiples of the spacing between adjacent two clamping cavities 41 along the moving direction of the moving cylinder 61. The guiding section can provide the guiding for the movement and retraction of the moving cylinder 61. In this case, after the moving cylinder 61 extends to drive the fixing mechanism 1 to move to any clamping cavity 41, the fixing mechanism 1 remains stationary, and the moving cylinder 61 retracts to wait for the next movement of the fixing mechanism 1, suitable for the situation where a moving cylinder 61 with a small stroke completes the installation operation of connectors 3 with a large stroke.

[0089] For the setting of the guiding section, it can be used to guide the movement of the moving cylinder 61. Specifically, it can be a guiding groove. The head and the end of the guiding groove are two limits. One corresponds to the position corresponding to the fixed end of the lifting cylinder 65 when the moving cylinder 61 extends, and the other corresponds to the position corresponding to the fixed end of the lifting cylinder 65 when the moving cylinder 61 retracts.

[0090] The distance between the head and the end of the guiding section corresponds to a multiple of the distance between two adjacent clamping cavities 41 along the moving direction of the moving cylinder 61. The multiple depends on the installation order of the connectors 3 on the device 2 and can be one time, two times or more.

[0091] The fixed end of the lifting cylinder 65 has a guiding column 651 that extends out of the fixing plate 62 and inserts into the guiding section. At least one guiding column 651 is provided. Please refer to Figure 1 、 Figure 7 , and the guiding column 651 can move within the guiding section to provide guidance for the movement route of the moving cylinder 61, ensuring that the fixing mechanism 1 can reliably move between the clamping cavities 41 to correspondingly and reliably install the connectors 3 at different positions.

[0092] Please refer to Figure 2 , the fixing mechanism 1 includes a fixing frame 11. The fixing frame 11 can form a placement space 12 for the device 2. Connecting holes are provided on the outer peripheral edge of the fixing frame 11, and fasteners 14 are provided in the connecting holes. The fasteners 14 are used to fix or limit the device 2 within the placement space 12. The setting of the placement space 12 is for the positioning of the device 2 installed on the fixing frame 11, and the setting of the fasteners 14 is what can be used to reliably install the device 2 on the fixing frame 11. Through this setting form, the reliability of the device 2 on the fixing mechanism 1 can be ensured, the accuracy of the device 2 moving with the fixing mechanism 1 to the clamping cavity 41 can be ensured, and the effect of the installation of the connector 3 affected by the offset of the device 2 can be avoided. Specifically, the fastener 14 can be a screw or a bolt, which is specifically determined in combination with the corresponding hole positions or connection positions on the device 2.

[0093] Please refer to Figure 2 , the fixing mechanism 1 includes a protruding shaft 13 that protrudes from the fixing frame 11 and is arranged away from the placement space 12. The protruding shaft 13 has a first part 131 that is clamped in the clamping cavity 41 and a second part 132 that is located in the moving space 43 and abuts against the side plate 42. The diameter of the first part 131 is smaller than the diameter of the second part 132. The protruding shaft 13 here is the part where the fixing mechanism 1 can be clamped or disengaged from the clamping cavity 41. The number of the protruding shafts 13 provided can be determined according to the actual situation. For example, multiple can be set to ensure the reliable support of the fixing mechanism 1 within the clamping cavity 41. The situation of setting multiple here means that it can be on the front and rear sides and the left and right sides of the fixing mechanism 1. The front, rear, left, and right here are the Figure 1 orientations defined with reference to the illustration.

[0094] By setting the protruding shaft 13 as a stepped shaft body, when the first part 131 is located within the clamping cavity 41, the second part 132 can provide a supporting force by abutting against the side plate 42, preventing the protruding shaft 13 from detaching and affecting the reliability of the joint 3 installation.

[0095] The fixing frame 7 is provided with multiple mounting positions perpendicular to the length direction of the side plate 42. The side plate 42 can be fixed to any one of the mounting positions to adjust the size of the moving space 43. Here, the length direction of the side plate 42 is the second direction, and the orientation perpendicular to the length direction of the side plate 42 is essentially the third direction perpendicular to the first and second directions. By setting the multiple mounting positions, the size of the moving space 43 can be adjusted according to actual needs to meet the use of different types of devices 2. Of course, if there is interference with the screwing mechanism 5, the screwing mechanism 5 can also be moved on the fixing frame 7 to match the use of different types of devices 2 to improve applicability.

[0096] Please refer to Figure 1 , the bottom of the fixing frame 7 is provided with universal wheels 8 for changing the position of the joint automatic tightening device. By setting the universal wheels 8, the position of the joint automatic tightening device can be changed according to on-site requirements. For example, if the device 2 is not convenient to move, this form can be used to achieve it. After moving to a certain position, the universal wheels 8 can be locked so that the automatic screwing device can be locked at a certain position for operation, improving the applicability of the device.

[0097] On the side of the side plate 42 away from the moving space 43, there are several reinforcing ribs. One end of the reinforcing rib is connected to the side plate 42, and the other end is connected to the fixing frame 7. By setting the reinforcing ribs, the structural strength of the side plate 42 can be guaranteed, its anti-deformation ability can be improved, the reliability and stability of the clamping cavity 41 can be ensured, and the reliability of the automatic screwing and installation of multiple joints 3 can be guaranteed.

[0098] Based on any of the above embodiments, please refer to Figure 4 , Figure 5 , the screwing mechanism 5 includes a sleeve 57. One end of the sleeve 57 is connected to a driving component for driving it to contact or disengage from the outer periphery of the joint 3. The other end of the sleeve 57 is provided with multiple-level clamping positions 571 arranged along its axial direction. The multiple-level clamping positions 571 are used to correspond to different driving distances of the driving component and different outer diameters of the joint 3.

[0099] The setting of the multiple-level clamping positions 571 of the sleeve 57 can correspond to joints 3 with various different outer diameter sizes. By screwing with the clamping position 571 corresponding to the outer diameter size of the joint 3 and the joint 3, the tightening of a specific type of joint 3 can be carried out specifically to ensure the reliability of the joint 3 installation.

[0100] The driving component can drive any clamping position 571 of the sleeve 57 to contact or disengage from the joint 3. Specifically, it means that after the driving component drives the sleeve 57 to move into contact with the joint 3, the joint 3 with the corresponding outer diameter size can be reliably screwed onto the device 2 by rotating the sleeve 57; after screwing, the driving component drives the sleeve 57 to move to disengage it from the joint 3.

[0101] The different driving distances of the driving component can be controlled based on the control element. Specifically, it means that corresponding driving programs can be set based on joints 3 with different outer diameter sizes to achieve the operation of automatically tightening the joint 3.

[0102] In this embodiment, by directly processing the sleeve 57, the installation of joints 3 with various different sizes can be completed on the same sleeve 57 without replacing the sleeve 57, making the operation more convenient and the applicability stronger.

[0103] Based on any of the above embodiments, please refer to Figure 4 , the driving component includes a first driving member 51 and a second driving member 52. The first driving member 51 is connected to the fixed frame 7 through a connecting frame 53. The second driving member 52 is connected to the first driving member 51 through a connecting plate 58 to achieve movement, and the second driving member 52 is connected to the sleeve 57 to achieve the rotation of the sleeve 57. The movement of the second driving member 52 is the movement of the sleeve 57 relative to approaching or departing from the joint 3, and the rotation of the second driving member 52 driving the sleeve 57 is the rotation of screwing the joint 3 onto the device 2.

[0104] The driving component further includes a guiding member, which is rotatably connected to the sleeve 57 to achieve rotational guidance; the guiding member here can specifically be in the form of a turntable, a faceplate, a bearing 55, etc., which can provide guidance when the second driving member 52 drives the sleeve 57 to rotate, ensuring that the rotation route of the sleeve 57 is reliable and accurate, and ensuring that the joint 3 can be reliably tightened.

[0105] Alternatively, the guiding member is slidably arranged relative to the second driving member 52 to achieve translational guidance when the second driving member 52 moves, ensuring the accuracy of the route of the sleeve 57 moving to approach or depart from the joint.

[0106] Based on any of the above embodiments, please refer to Figure 4 , the second driving member 52 is a driving motor connected to the first driving member 51 through a guiding plate 56. The output end of the driving motor is connected to the sleeve 57 through a coupling 54. The driving motor is connected to the sleeve 57 through the coupling 54 to be able to drive the sleeve 57 to rotate through the driving motor. The rotation here can be bidirectional to be applicable to the usage scenarios of screwing or unscrewing the joint 3.

[0107] At least one guiding plate 56 is provided along the axial direction of the sleeve 57. A guiding hole is provided in the guiding plate 56, and a guiding member is provided in the guiding hole. The guiding member is rotatably connected to one end of the coupling 54 which is connected to the sleeve 57. The guiding member is preferably a bearing 55. One end of the sleeve 57 connected to the coupling 54 is as Figure 5 shown as a shaft body structure. A plurality of guiding plates 56 can be provided. A bearing 55 can be nested in each guiding plate 56 so as to be able to contact the shaft body structure from multiple axial directions to guide the rotation of the sleeve 57 and ensure the precise reliability of the rotation of the sleeve 57.

[0108] On the basis of any of the above embodiments, a control mechanism is further included. The fixing mechanism 1 is provided with a scanning strip or a radio frequency card. The control mechanism is used to determine the type of the device 2 based on the information of the scanning strip or the radio frequency card so as to be able to control the driving component and the moving mechanism 6 to operate.

[0109] By binding the bar code or the radio frequency card to the supporting program of the control mechanism, when in use, the control mechanism scans the scanning strip or the radio frequency card on the fixing mechanism 1, and then the corresponding device joint installation program can be started, improving the intelligent and automated level of the device joint installation.

[0110] In this embodiment, it should be noted that the scanning strip and the radio frequency card are provided on the fixing mechanism 1, and each fixing mechanism 1 corresponds to a different device 2. Then, by equipping multiple sets of fixing mechanisms 1, the joint 3 installation operation of different types of devices 2 can be carried out, improving the overall applicability of the equipment.

Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
