[0001] The present invention relates to the technical field of rotating member driving, and in particular to a driving mechanism for driving a rotating member to rotate. At the same time, the present invention also relates to a vehicle door hanger driving device using the driving mechanism. Background Art

[0002] The rotating part drive mechanism is a device that provides power to drive the rotating part to rotate. Its main function is to realize the rotation of the rotating part and convert the power it provides into the torque and speed required for the rotation of the rotating part.

[0003] Taking the rotating part as a car door hanger as an example, the car door hanger is a special tool used to hang and fix the car door, which plays a pivotal role in the process of automobile manufacturing, maintenance and transportation. The existing car door hanger mainly includes a hanger body, which can rotate around the hanger shaft, and door clamps are arranged on both sides of the hanger body, and the door clamps on both sides are used to clamp different car doors.

[0004] During the use of the existing door hanger, when the door clamp needs to be switched, the door hanger is rotated completely manually, and the existing driving mechanism for driving the rotating member is inconvenient to connect with the door hanger and is not suitable for driving the existing door hanger to rotate. Summary of the invention

[0005] In view of this, the present invention aims to provide a driving mechanism suitable for driving a rotating member such as a door hanger to rotate.

[0006] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] A driving mechanism, used to drive a rotating member to rotate, comprises a mounting member, a transmission member, a limiting member and a driving part;

[0008] A guide structure is provided between the mounting member and the transmission member, and the guide structure is used to guide the transmission member to rotate relative to the mounting member around the rotation axis of the rotating member;

[0009] The transmission member is provided with a first plug-in portion, and the first plug-in portion can be plug-connected with the rotating member in a direction orthogonal to the rotation axis;

[0010] The limiting member is arranged on the mounting member, and the limiting member is used to limit the position of the transmission member along the rotation axis;

[0011] The driving part is arranged on the mounting part, and is transmission-connected with the driving part, and is driven by the driving part. The transmission part can drive the rotating part to rotate.

[0012] Furthermore, the guide structure includes a guide groove provided on the transmission member, and a guide wheel rotatably provided on the mounting member, at least a portion of the guide wheel is embedded in the guide groove; and / or, the limiting members on each side include a plurality of limiting wheels rotatably provided on the mounting member, and the plurality of limiting wheels on each side are spaced apart and distributed on the same arc centered on the rotation axis.

[0013] Furthermore, the driving part includes a first driving member, and a driving rod connected to the power output end of the first driving member; the driving rod is slidably arranged on the mounting member, and the driving rod and the transmission member are meshed and connected; when the first driving member drives the driving rod to slide relative to the mounting member, it can drive the transmission member to rotate.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The driving mechanism described in the present invention can be connected to the rotating member by plugging the transmission member through the setting of the transmission member. The driving unit drives the transmission member to drive the rotating member to rotate, so that the driving connection with the rotating member such as the door hanger can be realized, and it also has the advantage of convenient operation. At the same time, by setting the limit member, there is no need to set the rotating bearing, and there is no need to change the structure of the rotating member such as the door hanger. It can replace manual driving to realize the rotation of the rotating member such as the door hanger, and has good practicality.

[0016] In addition, the design of the guide structure is mainly used to ensure the stable and controllable rotation of the transmission member on the mounting member. The guide structure includes two parts: a guide groove and a guide wheel. The guide groove is a groove set on the transmission member to guide or limit the moving path of the transmission member, and the guide wheel is rotatably mounted on the mounting member and embedded in the guide groove. As the transmission member rotates, the guide wheel will roll in the guide groove, thereby ensuring that the transmission member rotates smoothly along the predetermined path, which can not only ensure the movement stability of the transmission member, but also reduce friction, making the transmission member rotate more smoothly.

[0017] The main function of the limiter is to limit the movement of the transmission member in the length direction of the rotation axis to ensure that the transmission member does not exceed the predetermined range during the rotation process and can rotate smoothly. In terms of specific structure, the limiter is realized by a plurality of limit wheels, which are rotatably arranged on the mounting member. The plurality of limit wheels on each side are spaced apart on the arc centered on the rotation axis, which can ensure that the transmission member rotates stably and smoothly within the predetermined range, and can also reduce the friction and wear of the transmission member by dispersing the contact points, thereby improving the durability of the overall structure.

[0018] Another object of the present invention is to provide a vehicle door hanger driving device for driving the vehicle door hanger to rotate, which comprises the driving mechanism as described above; the vehicle door hanger constitutes the rotating member.

[0019] Furthermore, it also includes a mounting carrier and a floating mechanism; the mounting member is arranged on the mounting carrier through the floating mechanism; the floating mechanism includes an elastic member arranged between the mounting carrier and the mounting member, and when the driving mechanism deviates from its own mounting position, the elastic member stores energy; the elastic member releases energy to drive the driving mechanism to reset.

[0020] Furthermore, it also includes a pin pulling device arranged on the mounting carrier, the pin pulling device includes a bracket seat, a pin pulling member, and a first position adjustment mechanism arranged between the bracket seat and the pin pulling member; the first position adjustment mechanism is used to drive the pin pulling member to slide in a first direction and a second direction relative to the bracket seat in sequence, so that after the pin pulling member is plugged and connected with the locating pin of the vehicle door hanger along the first direction, the locating pin is pulled out along the second direction; wherein the first direction and the second direction intersect.

[0021] Furthermore, the first position adjustment mechanism includes a second driving unit, a mobile bracket and a third driving unit; the second driving unit is arranged between the bracket seat and the mobile bracket, and the second driving unit is used to drive the mobile bracket to move along the first direction relative to the bracket seat; the third driving unit is arranged between the mobile bracket and the pin pulling member, and the third driving unit is used to drive the pin pulling member to move along the second direction relative to the mobile bracket.

[0022] Furthermore, the pin pulling device further comprises a fourth driving part, the fourth driving part is respectively connected to the mounting carrier and the bracket seat, and the fourth driving part is used to drive the pin pulling device to swing relative to the mounting carrier.

[0023] Furthermore, the mounting carrier includes a carrier body, a mounting portion, and a second position adjustment mechanism arranged between the carrier body and the mounting portion; the second position adjustment mechanism is used to drive the mounting portion to slide along a third direction and / or a fourth direction relative to the carrier body, so that the transmission member of the drive mechanism and the door hanger can be plugged and connected; wherein the third direction and the fourth direction intersect.

[0024] Furthermore, the second position adjustment mechanism includes an intermediate bracket, a fifth driving part arranged between the carrier body and the intermediate bracket, and a sixth driving part arranged between the intermediate bracket and the mounting part; the fifth driving part is used to drive the intermediate bracket to slide along a third direction relative to the carrier body; the sixth driving part is used to drive the mounting part to slide along a fourth direction relative to the intermediate bracket; and / or, the mounting carrier also includes a base, the carrier body is installed on the base, and a height adjustment structure for adjusting the height position of the carrier body on the base is provided between the base and the mounting carrier.

[0025] The door hanger driving device of the present invention has the same beneficial effects as the aforementioned driving mechanism relative to the prior art, which will not be described in detail herein.

[0026] In addition, the mounting carrier is the foundation or supporting part of the entire mechanical structure, which is used to fix and support the driving mechanism. The floating mechanism is set to allow the driving mechanism to have a certain floating or moving range on the mounting carrier. When the driving mechanism deviates from its original mounting position due to external force, the elastic member will begin to store energy, and it will store the energy generated by the deviation from the original mounting position. Once the external force disappears or weakens to a degree sufficient for the elastic member to release energy, it will begin to release the previously stored energy and drive the driving mechanism back to its original mounting position, which is conducive to the smooth plug-in connection between the transmission member and the rotating member, and the plug-in connection process is not a hard connection but a soft connection, which can prevent damage to the transmission member or the rotating member during the plug-in process.

[0027] In addition, the pin pulling device is a mechanism installed on the mounting carrier and is specifically used for plugging and pulling out the locating pins of the door hanger. It is mainly composed of a bracket seat, a pin pulling piece, and a first position adjustment mechanism. Among them, the bracket seat is the fixed part of the pin pulling device, which is used to support and fix the pin pulling piece and the first position adjustment mechanism. The pin pulling piece is the movable part of the pin pulling device, which is used to perform actual plugging and pulling operations with the locating pins of the door hanger. Its shape and size usually match the locating pin to ensure that the two can fit closely.

[0028] The first position adjustment mechanism is the core part of the pin pulling device, which is used to drive the pin pulling member to slide relative to the bracket seat in two intersecting directions, such as the first direction and the second direction. This allows the pin pulling member to first be plugged and connected with the positioning pin in the first direction, and then the positioning pin is pulled out in the second direction. The intersection of the first direction and the second direction can ensure that the pin pulling member can move flexibly in two directions, thereby completing the plugging and pulling operations. This intersection structure is used to ensure that the pin pulling member will not be subject to unnecessary obstructions or interference during the movement process, thereby improving the degree of automation and work efficiency.

[0029] Furthermore, the second driving part is a driving device arranged between the bracket seat and the mobile bracket, and its main function is to drive the mobile bracket to move in the first direction relative to the bracket seat. The mobile bracket is the middle part connecting the second driving part and the third driving part, and it moves in the first direction with the driving of the second driving part, and serves as the installation base of the third driving part, which can withstand the force and torque generated by the pin pulling member during the movement. The third driving part is a driving device arranged between the mobile bracket and the pin pulling member, and its main function is to drive the pin pulling member to move in the second direction relative to the mobile bracket.

[0030] The first position adjustment mechanism can realize the flexible movement of the pin pulling member in two intersecting directions through the coordinated work of the second driving part and the third driving part. This design can not only improve the automation degree and work efficiency of the pin pulling device, but also enhance its ability to adapt to different working environments and requirements.

[0031] As for the newly added fourth driving part, its two ends are respectively pivotally connected to the mounting carrier and the bracket seat, which means that the fourth driving part can rotate or swing relative to the mounting carrier and the bracket seat. Driven by the fourth driving part, the pin pulling device can swing relative to the mounting carrier. This structure can be used to adjust the angle or position of the pin pulling member relative to the door hanger positioning pin to meet different work requirements.

[0032] The mounting carrier includes a carrier body, a mounting portion and a second position adjustment mechanism, wherein the carrier body is the main part of the mounting carrier and is used to provide a stable support and fixing point. The mounting portion is a mounting base for mounting a driving mechanism, which is connected to the carrier body through a second position adjustment mechanism and can be adjusted in position within a certain range. The second position adjustment mechanism is a driving device arranged between the carrier body and the mounting portion, and its main function is to drive the mounting portion to move relative to the carrier body along the third direction and / or the fourth direction. This movement adjustment enables the transmission member of the driving mechanism to be plugged and connected with the door hanger. The third direction and the fourth direction are intersecting, which means that they are not parallel, but there is a certain angle between them.

[0033] As for the fifth driving unit, it is a driving device arranged between the carrier body and the intermediate bracket, which is responsible for driving the intermediate bracket to move along the third direction relative to the carrier body. The intermediate bracket is a bridge connecting the fifth driving unit and the sixth driving unit, and plays a role of transition and support. It moves along the third direction with the drive of the fifth driving unit, and provides stable support for the sixth driving unit and the mounting unit. The sixth driving unit is a driving device arranged between the intermediate bracket and the mounting unit, which is responsible for driving the mounting unit to slide along the fourth direction relative to the intermediate bracket. The fourth direction here intersects with the third direction, which refers to a direction perpendicular to or at a certain angle to the third direction.

[0034] By introducing the fifth driving part, the intermediate bracket and the sixth driving part, the design of the second position adjustment mechanism can be further improved. This design can not only improve the flexibility and adaptability of the mechanical structure, but also provide the possibility for its application in more complex and changeable working environments.

[0035] The provided base is the basic part of the mounting carrier, which provides a stable mounting foundation for the carrier body. The height adjustment structure is an adjustment device provided between the base and the mounting carrier, and its main function is to adjust the height position of the carrier body relative to the base. By introducing the base and the height adjustment structure, the design of the mounting carrier can be further improved, thereby improving the flexibility and adaptability of the mechanical structure, and also providing the possibility for its application in more complex and changeable working environments. At the same time, combined with the use of the second position adjustment mechanism, the mounting carrier can be accurately adjusted in multiple dimensions, thereby ensuring accurate connection with the door hanger.

[0058] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0059] Embodiment 1

[0060] The present embodiment relates to a driving mechanism, which can drive a rotating member such as the door hanger 5 in the present embodiment to rotate, thereby reducing manual labor intensity and improving the efficiency of switching the door clamp 503 .

[0061] Based on the above design concept, an exemplary structure of the driving mechanism of this embodiment is as follows: Figure 1 and Figure 2 As shown, in terms of overall structure, the driving mechanism of this embodiment mainly includes a mounting member 1, a transmission member 2, a limiting member 3 and a driving part.

[0062] Among them, a guide structure 4 is provided between the mounting member 1 and the transmission member 2, and the guide structure 4 is used to guide the transmission member 2 to rotate relative to the mounting member 1 around the rotation axis of the rotating member. A first plug-in portion 201 is provided on the transmission member 2, and the first plug-in portion 201 can be plugged and connected with the rotating member in a direction orthogonal to the rotation axis. After the transmission member 2 and the rotating member are plugged and connected, they are coaxially arranged. A limiter 3 is provided on the mounting member 1, and the limiter 3 is used to limit the position of the transmission member along the rotation axis.

[0063] The aforementioned driving part is arranged on the mounting part 1, and the transmission part 2 is connected to the driving part by transmission; driven by the driving part, the transmission part 2 can drive the rotating part to rotate around the aforementioned rotation axis. It should be noted that in this embodiment, the rotation axis of the rotating part is along the vertical direction. The driving mechanism of this embodiment is safe and reliable, saves time and effort, and can realize the scientific and automated rotation of the door hanger 5.

[0064] It should also be noted that in this embodiment, the rotating member is described as a door hanger 5. It should be understood that the rotating member can be other parts that need to rotate in addition to the door hanger 5.

[0065] In order to better understand the driving mechanism of this embodiment, first refer to Figure 7The structure shown mainly includes a sling body 501, the cross section of which is square and the length of which extends in the vertical direction, and door clamps 503 are arranged on both sides of the sling body 501. The sling body 501 rotates around the sling shaft 502, and can rotate the required door clamp 503 to a required position.

[0066] A positioning pin 504 is provided at the lower part of the hanger body 501. The hanger body 501 can rotate around the hanger shaft 502 only after the positioning pin 504 is pulled out. When the positioning pin 504 is not pulled out, the hanger body 501 cannot rotate around the hanger shaft 502. The specific structure of the door hanger 5 can refer to the existing structure.

[0067] The driving mechanism of this embodiment is to drive the aforementioned door hanger 5 to rotate without changing the structure of the existing door hanger 5 .

[0068] In terms of specific structure, Figure 2 As shown, a plug-in slot is provided at the rotation center of the transmission member 2 of this embodiment, and an opening is provided on one side of the plug-in slot. A part of the hanger body 501 can be embedded in the plug-in slot from the opening on one side, so that the rotation center of the transmission member 2 and the rotation center of the hanger body 501 are coaxial, so that the transmission member 2 can drive the vehicle door hanger 5 to rotate around the axial center line of the hanger shaft 502.

[0069] In the above structure, the plug-in groove constitutes the first plug-in portion 201 provided on the transmission member 2, and the hanger body 501 constitutes the first plug-in matching portion of the door hanger 5. The first plug-in portion 201 and the first plug-in matching portion are plug-connected, so that the transmission member 2 can drive the rotating member to rotate.

[0070] It should be noted that, in order to facilitate the smooth insertion of a part of the sling body 501 into the plug-in slot, a guide portion is provided at the opening on one side of the plug-in slot, which is specifically a chamfer provided at the opening of the plug-in slot, so that a part of the sling body 501 can be smoothly inserted into the plug-in slot. In this embodiment, the guide portion specifically includes a guide plate 202 detachably connected to the opening, which can be connected to the transmission member 2 by, for example, screwing and clamping.

[0071] In order to improve the applicability of the transmission member 2, adjustment washers 203 are provided on both sides of the plug-in slot. By changing the thickness and number of the adjustment washers 203 on both sides, the width of the plug-in slot can be adjusted, so that the transmission member 2 can be suitable for rotating door hangers 5 of various specifications. In a preferred embodiment, the adjustment washers 203 are detachably installed in the plug-in slot, for example, screwed to the transmission member 2 by countersunk screws.

[0072] It should be noted that, in addition to improving the application range of the driving mechanism, the adjustment gasket 203 can also be made of materials such as rubber silicone to reduce wear and noise during the plug-in connection between the transmission member 2 and the rotating member.

[0073] like Figure 2 and Figure 6 As shown, preferably, the transmission member 2 is semicircular, and its outer peripheral wall is provided with external teeth, so that the transmission member 2 is a semicircular gear. It should be understood that the center of the rotating member can be set as other structures that are convenient for plugging and connecting with the rotating member and can drive the rotating member to rotate in addition to the above structure.

[0074] In order to facilitate the smooth rotation of the transmission member 2, as a preferred embodiment, the guide structure 4 includes a guide groove 401 arranged on the transmission member 2, and a guide wheel 402 rotatably arranged on the mounting member 1, and at least part of the guide wheel 402 is embedded in the guide groove 401.

[0075] Here, the design of the guide structure 4 is mainly used to ensure the stable and controllable rotation of the transmission member 2 on the mounting member 1. The guide structure 4 includes two parts: a guide groove 401 and a guide wheel 402. The guide groove 401 is a groove arranged on the transmission member 2, which is used to guide or limit the moving path of the transmission member 2, and the guide wheel 402 is rotatably mounted on the mounting member 1 and embedded in the guide groove 401.

[0076] In this embodiment, the rotation center of the transmission member 2 is along the vertical direction, and the axial center line of the guide wheel 402 is also along the vertical direction. As the transmission member 2 rotates, the guide wheel 402 rolls in the guide groove 401, thereby ensuring that the transmission member 2 rotates smoothly along the predetermined path, which can not only ensure the movement stability of the transmission member 2, but also reduce friction, making the transmission member 2 rotate more smoothly.

[0077] In order to facilitate the smooth rotation of the transmission member 2, the limiting members 2 are disposed on both sides of the transmission member 2 along the rotation axis. As a preferred embodiment, the limiting members 3 on each side include a plurality of limiting wheels rotatably disposed on the mounting member 1, and the plurality of limiting wheels on each side are spaced apart on the same arc centered on the rotation axis. In this embodiment, the axial direction of each limiting wheel is along the horizontal direction, and the axial center line of each limiting wheel passes through the rotation axis of the rotation center of the transmission member 2, so that the transmission member 2 rotates smoothly.

[0078] In this embodiment, the main function of the limiter 3 is to limit the movement of the transmission member 2 in the length direction of the rotation axis, so as to ensure that the transmission member 2 does not exceed the predetermined range during the rotation process and can rotate smoothly. In terms of specific structure, the limiter 3 is realized by a plurality of limiter wheels, which are rotatably arranged on the mounting member 1, and the plurality of limiter wheels on each side are spaced apart on an arc centered on the rotation axis, which can ensure that the transmission member 2 rotates stably and smoothly within the predetermined range, and can also reduce the friction and wear of the transmission member 2 by dispersing the contact points, thereby improving the durability of the overall structure.

[0079] In this embodiment, the limiting member 3 is used to support the transmission member 2. At the same time, during the entire process of the rotation of the transmission member 2, the limiting member 3 always supports the member 2, that is, the limiting member 3 is used to ensure the smooth rotation of the transmission member 2 during the rotation of the transmission member 2. It should be understood that in addition to being set as a limiting wheel, the limiting member 3 can also be other structures that can prevent the transmission member 2 from moving along the rotation axis during the rotation of the transmission member 2, for example, it can be a limiting plate, a limiting block, etc.

[0080] Still refer to Figure 2 and Figure 6 As shown, the limit members 3 are divided into two groups, each group of limit members 3 has two limit members 3, and the two limit members 3 are placed on both sides of the transmission member 2. The installation space between the two limit members 3 is placed in the guide groove 401, which is convenient for the overall arrangement and conducive to the stable and reliable rotation of the transmission member 2. The angle between the rotation axes of the two limit members 3 on each side of the transmission member 2 is 90°, so that the transmission member 2 can rotate smoothly. It should be understood that the number of groups of limit members 3, the number of limit members 3, and the angle between the rotation axes of the two limit members 3 on each side of the transmission member 2 can be adjusted according to actual needs.

[0081] As a preferred embodiment, the aforementioned driving part includes a first driving member 6, and a driving rod 7 connected to the power output end of the first driving member 6. The driving rod 7 is slidably arranged on the mounting member 1, and the length direction and sliding direction of the driving rod 7 are both along the tangent direction of the outer periphery of the transmission member 2. Specifically, the length direction and sliding direction of the driving rod 7 are both along the third direction described below.

[0082] A rack is provided on one side of the driving rod 7 to facilitate meshing of the driving rod 7 and the transmission member 2, so that when the first driving member 6 drives the driving rod 7 to slide relative to the mounting member 1, the driving rod 7 can drive the transmission member 2 to rotate.

[0083] In this structure, the first driving member 6 is the power source of the entire driving part and is responsible for providing the necessary driving force. In this embodiment, the first driving member 6 is a cylinder. It should be understood that the first driving member 6 can be a motor, a hydraulic motor or other forms of power devices in addition to the cylinder.

[0084] The driving part includes not only the first driving member 6 and the driving rod 7, but also other structures that can drive the transmission member 2 to rotate. The aforementioned driving rod 7 is connected to the power output end of the first driving member 6, and is mainly used to transmit power to the transmission member 2.

[0085] It should be noted that the aforementioned mounting member 1 is a mounting carrier 9 that fixes and supports the entire drive mechanism to ensure the stability and reliability of the drive mechanism during operation. Preferably, the mounting member 1 is specifically a mounting plate, which is arranged parallel to the horizontal plane.

[0086] In order to improve the stability of the movement of the driving rod 7, a first slide rail 8 is provided between the driving rod 7 and the mounting member 1, and the first slide rail 8 can refer to the existing structure. The axial direction of the power output shaft of the aforementioned first cylinder is parallel to the sliding direction of the driving rod 7, and the power output shaft is arranged on the side of the first cylinder facing away from the transmission member 2. The power output shaft of the first cylinder is connected to the driving rod 7 through a connecting rod 601, and the connecting rod 601 is "L"-shaped, which is convenient for overall layout and helps to save occupied space.

[0087] In order to improve the reliability of the operation of the driving mechanism, in a preferred embodiment, a limiting portion 602 is provided on the connecting rod 601. When the first cylinder drives the driving rod 7 to slide, the limiting portion 602 is used to limit the sliding limit position of the driving rod 7. In this embodiment, a mounting bracket for mounting the first cylinder is provided on the mounting member 1. When the driving rod 7 slides to the limit position, the limiting portion 602 can press against the mounting bracket of the first cylinder.

[0088] Preferably, the limiting portion 602 is detachably mounted on the connecting rod 601, so as to facilitate replacement of different limiting portions 602 to adjust the sliding limit position of the driving rod 7. In this embodiment, the limiting portion 602 specifically includes a bolt screwed on the connecting rod 601, and a nut that fixes the bolt on the connecting rod 601 and is screwed to the bolt.

[0090] Embodiment 2

[0091] This embodiment relates to a door hanger driving device for driving a door hanger 5 to rotate, which includes a driving mechanism as in the first embodiment, and the door hanger 5 constitutes the rotating member in the first embodiment.

[0092] like Figure 1 As shown, as a preferred embodiment, the door hanger driving device of this embodiment includes a mounting carrier 9 and a floating mechanism 10. The mounting member 1 of the driving mechanism of the first embodiment is arranged on the mounting carrier 9 through the floating mechanism 10.

[0093] In terms of specific structure, the floating mechanism 10 includes an elastic member 1002 arranged between the mounting carrier 9 and the mounting member 1. When the driving mechanism deviates from its own mounting position, the elastic member 1002 stores energy; the elastic member 1002 releases energy to drive the driving mechanism to reset.

[0094] As in this embodiment, the floating mechanism 10 also includes a guide shaft 1003 fixed on the mounting portion 902 described below. The aforementioned elastic member 1002 specifically includes two springs sleeved on the guide shaft 1003. The bottom of the mounting member 1 is provided with a ring sleeved on the guide shaft 1003 and located between the two springs.

[0095] Both ends of the guide shaft 1003 are provided with limit blocks 1004, and the limit blocks 1004 at both ends are used to block the two ends of the two springs. In this way, the driving mechanism slides in any direction of the guide shaft 1003, and the elastic member 1002 can store energy.

[0096] In this embodiment, the axial direction of the guide shaft 1003 and the sliding direction of the second slide rail 1001 described below are both along the fourth direction described below, so that the floating direction of the entire driving mechanism is along the fourth direction.

[0097] In the above structure, the mounting carrier 9 is the foundation or supporting part of the entire mechanical structure, and is used to fix and support the driving mechanism. The floating mechanism 10 is provided to allow the driving mechanism to have a certain floating or moving range on the mounting carrier 9. When the driving mechanism deviates from its original mounting position due to external force, the elastic member 1002 will start to store energy, and it will store the energy generated by the deviation from the original mounting position.

[0098] Once the external force disappears or weakens to a level sufficient for the elastic member 1002 to release energy, it will begin to release the previously stored energy, driving the drive mechanism back to its original installation position, facilitating the smooth plug-in connection between the transmission member 2 and the rotating member. The plug-in connection process is not a hard connection but a soft connection, which can prevent damage to the transmission member 2 or the rotating member during the plug-in process.

[0099] In order to improve the floating stability of the mounting member 1, two second slide rails 1001 are provided between the mounting member 1 and the mounting portion 902, and the guide shaft 1003 and the elastic member 1002 are provided between the two second slide rails 1001, so that the mounting member 1 can float smoothly relative to the driving mechanism.

[0100] As a preferred embodiment, the driving mechanism of this embodiment further includes a pin pulling device provided on the mounting carrier 9, such as Figure 5 As shown, the pin pulling device includes a support seat 11, a pin pulling member 12, and a first position adjustment mechanism disposed between the support seat 11 and the pin pulling member 12.

[0101] The first position adjustment mechanism is used to drive the pin puller 12 to slide in the first direction and the second direction relative to the bracket seat 11, so that after the pin puller 12 is plugged and connected with the positioning pin 504 of the door hanger 5 in the first direction, the positioning pin 504 can be pulled out in the second direction; wherein the first direction and the second direction intersect. In this embodiment, the first direction and the second direction are both arranged in the horizontal direction.

[0102] It should be noted that the pin pulling device is a mechanism installed on the mounting carrier 9 and is specifically used for inserting and removing the positioning pin 504 of the door hanger 5. It is mainly composed of a bracket seat 11, a pin pulling member 12, and a first position adjustment mechanism. Among them, the bracket seat 11 is the fixed part of the pin pulling device, which is used to support and fix the pin pulling member 12 and the first position adjustment mechanism. The pin pulling member 12 is the movable part of the pin pulling device, which is used to perform actual insertion and removal operations with the positioning pin 504 of the door hanger 5. Its shape and size are usually matched with the positioning pin 504 to ensure that the two can fit closely.

[0103] The first position adjustment mechanism is the core part of the pin pulling device, and is used to drive the pin pulling member 12 to slide relative to the bracket seat 11 in two intersecting directions, such as the first direction and the second direction. This allows the pin pulling member 12 to first be plugged and connected with the positioning pin 504 in the first direction, and then the positioning pin 504 can be pulled out in the second direction. The intersection of the first direction and the second direction can ensure that the pin pulling member 12 can move flexibly in two directions, thereby completing the plugging and pulling operations. This intersecting structure is used to ensure that the pin pulling member 12 will not be subject to unnecessary obstructions or interference during the movement process, thereby improving the degree of automation and work efficiency.

[0104] It should be understood that the first position adjustment mechanism may be in various forms, such as a slide rail, a lead screw, a cylinder, etc., depending on application needs and design requirements. As a preferred embodiment, the first position adjustment mechanism includes a second drive unit 13, a movable bracket 14 and a third drive unit 15.

The mobile bracket 14 is the middle part connecting the second driving part 13 and the third driving part 15. It moves along the first direction with the drive of the second driving part 13, and serves as the installation base of the third driving part 15, which can withstand the force and torque generated by the pin pulling member 12 during the movement. The third driving part 15 is a driving device arranged between the mobile bracket 14 and the pin pulling member 12, and its main function is to drive the pin pulling member 12 to move along the second direction relative to the mobile bracket 14.

[0107] The design of the aforementioned movable bracket 14 should ensure sufficient rigidity and stability to withstand the force and torque generated during the movement of the pin pulling member 12. As in this embodiment, the movable bracket 14 is preferably in a plate shape to facilitate overall arrangement.

[0108] In the above structure, the first position adjustment mechanism can realize the flexible movement of the pin pulling member 12 in two intersecting directions through the coordinated work of the second drive unit 13 and the third drive unit 15. This design can not only improve the automation level and work efficiency of the pin pulling device, but also enhance its ability to adapt to different working environments and needs.

The second driving part 13 and the third driving part 15 are both cylinders, and it should be understood that in addition to the second cylinder, other forms of driving devices can also be used, such as motors, cylinders, hydraulic cylinders, etc., depending on application needs and design requirements.

[0110] In order to facilitate the installation of the third driving unit 15, a seventh mounting plate 1501 is fixedly provided on the mobile bracket 14. Preferably, the seventh mounting plate 1501 is L-shaped to facilitate the installation of the third driving unit 15 on the mobile bracket 14. In a preferred embodiment, the aforementioned pin puller 12 is provided with a plug-in groove, which constitutes a second plug-in portion 1201 provided on the pin puller 12, so as to facilitate plugging and connecting with the positioning pin 504 on the door hanger 5, specifically, the positioning pin 504 is embedded in the plug-in groove on the pin puller 12.

[0111] In order to facilitate the smooth movement of the pin puller 12, the pin puller 12 is fixedly mounted on the power output end of the third driving unit 15 through the fifth mounting plate 1202 and the sixth mounting plate 1203, and in a preferred embodiment, the fifth mounting plate 1202 is "L" shaped, and the fifth mounting plate 1202, the sixth mounting plate 1203 and the pin puller 12 are fixedly connected together.

[0114] In a preferred embodiment, both ends of the fourth driving part 16 are pivotally connected to the mounting carrier 9 and the bracket seat 11 respectively, and the fourth driving part 16 is used to output a linear driving force so that the pin pulling device can swing relative to the mounting carrier 9 .

[0115] The fourth driving part 16 newly added here is pivotally connected at both ends to the mounting carrier 9 and the bracket seat 11, which means that the fourth driving part 16 can rotate or swing relative to the mounting carrier 9 and the bracket seat 11. The main function of the fourth driving part 16 is to output a linear driving force. Through the drive of the fourth driving part 16, the pin pulling device can swing relative to the mounting carrier 9. This structure can be used to adjust the angle or position of the pin pulling member 12 relative to the positioning pin 504 of the door hanger 5 to meet different working requirements.

[0116] In this embodiment, the fourth driving part 16 is specifically a cylinder, the third mounting plate 1601 is fixed on the aforementioned mounting carrier 9, the fourth mounting plate 1603 is fixed on the bracket seat 11, and the two ends of the fourth driving part 16 are respectively pivoted to the third mounting plate 1601 and the fourth mounting plate 1603, and the two pivot axes are arranged in the vertical direction. In order to facilitate the bracket seat 11 to drive the pin pulling device to swing relative to the mounting carrier 9, the bracket seat 11 is pivoted to the mounting carrier 9 through the connecting shaft 1602, and the axial direction of the connecting shaft 1602 is arranged in the vertical direction.

[0117] As a preferred embodiment, Figures 2 to 4 As shown, the aforementioned mounting carrier 9 includes a carrier body 901, a mounting portion 902, and a second position adjustment mechanism disposed between the carrier body 901 and the mounting portion 902. The second position adjustment mechanism is used to drive the mounting portion 902 to slide along the third direction and / or the fourth direction relative to the carrier body 901, so that the transmission member 2 of the driving mechanism and the door hanger 5 can be plugged and connected; wherein the third direction and the fourth direction intersect.

[0118] It should be noted that the mounting carrier 9 includes a carrier body 901, a mounting portion 902 and a second position adjustment mechanism, wherein the carrier body 901 is the main part of the mounting carrier 9, and it may take various forms, such as a frame, a base, etc., to provide a stable support and a fixing point. The mounting portion 902 is a mounting base for mounting the driving mechanism, which is connected to the carrier body 901 through the second position adjustment mechanism, and can be adjusted in position within a certain range.

[0119] The second position adjustment mechanism is a driving device disposed between the carrier body 901 and the mounting portion 902, and its main function is to drive the mounting portion 902 to move along the third direction and / or the fourth direction relative to the carrier body 901, and this movement adjustment enables the transmission member 2 of the driving mechanism to be plugged and connected with the door hanger 5. The third direction and the fourth direction are intersecting structures, which means that they are not parallel, but have a certain angle.

[0120] As a preferred embodiment, the second position adjustment mechanism includes a fifth driving unit 17, an intermediate bracket 18 and a sixth driving unit 19; the fifth driving unit 17 is arranged between the carrier body 901 and the intermediate bracket 18, and the fifth driving unit 17 is used to drive the intermediate bracket 18 to slide along the third direction relative to the carrier body 901; the sixth driving unit 19 is arranged between the intermediate bracket 18 and the mounting unit 902, and the sixth driving unit 19 is used to drive the mounting unit to slide along the fourth direction relative to the intermediate bracket 18.

[0121] The fifth driving unit 17 is a driving device disposed between the carrier body 901 and the intermediate bracket 18, and is responsible for driving the intermediate bracket 18 to move along the third direction relative to the carrier body 901. In a preferred embodiment, the fifth driving unit 17 is mounted on the carrier body 901 through the second mounting plate 905, and the intermediate bracket 18 is connected to the power output end of the fifth driving unit 17. In order to improve the stability of the movement of the intermediate bracket 18, two sets of third slide rails 20 are disposed between the intermediate bracket 18 and the carrier body 901, and the two sets of third slide rails 20 are arranged at intervals along the fourth direction.

[0122] The intermediate bracket 18 is a bridge connecting the fifth driving part 17 and the sixth driving part 19 , and plays a role of transition and support. It moves along the third direction as the fifth driving part 17 is driven, and provides stable support for the sixth driving part 19 and the mounting part 902 .

[0123] The sixth driving part 19 is a driving device arranged between the intermediate bracket 18 and the mounting part 902, which is responsible for driving the mounting part 902 to slide along the fourth direction relative to the intermediate bracket 18. The fourth direction here intersects with the third direction and refers to a direction perpendicular to or at a certain angle to the third direction.

[0124] In a preferred embodiment, the sixth driving unit 19 is mounted on the intermediate bracket 18 via the first mounting plate 904, and the mounting portion 902 is mounted on the power output end of the sixth driving unit 19 via the connecting portion 903. In order to improve the stability of the movement of the mounting portion 902, two sets of fourth slide rails 21 are provided between the driving mechanism and the intermediate bracket 18, and the two sets of fourth slide rails 21 are arranged at intervals along the third direction.

[0125] In the above structure, by introducing the fifth driving part 17, the intermediate bracket 18 and the sixth driving part 19, the design of the second position adjustment mechanism can be further improved. This design can not only improve the flexibility and adaptability of the mechanical structure, but also provide the possibility for its application in more complex and changeable working environments.

[0126] It should be understood that it is also feasible to provide only one of the fifth driving unit 17 and the sixth driving unit 19. For example, when only the fifth driving unit 17 is provided, the fourth slide rail 21 can be omitted, and only one of the mounting unit 902 and the intermediate bracket 18 is retained or both are integrated into an integral structure. When only the sixth driving unit 19 is provided, the third slide rail 20 can be omitted, and the intermediate bracket 18 can be directly installed on the carrier body 901, or the intermediate bracket 18 can also be omitted, and the first mounting plate 904 can be directly fixed on the carrier body 901.

[0127] Preferably, the fifth driving unit 17 and the sixth driving unit 19 mentioned above preferably use cylinders. It should be understood that in addition to cylinders, other driving methods such as motors and hydraulic cylinders can also be used, depending on application needs and design requirements.

[0128] For example, in an adjustment process, the fifth driving unit 17 works first to drive the intermediate bracket 18 to move to a predetermined position along the third direction. Then, the sixth driving unit 19 works to drive the mounting portion 902 to move along the fourth direction relative to the intermediate bracket 18, so as to ensure the accurate insertion of the transmission member 2 and the door hanger 5. This collaborative working mode enables the second position adjustment mechanism to flexibly adjust the position of the driving mechanism to adapt to different working environments and requirements.

[0129] It should be noted that, in order to facilitate the overall arrangement, an air source processing mechanism 24 and an air pressure control module 25 are also installed on the carrier body 901. The air source processing mechanism 24 is used to provide a clean and dry air source, and the air pressure control module 25 can adopt an existing control valve assembly, which is used to connect with each cylinder to control the action of each cylinder. Both the air source processing mechanism 24 and the air pressure control module 25 can adopt existing structures.

[0130] As a preferred embodiment, still refer to Figures 2 to 4As shown, the mounting carrier 9 further includes a base 22 , the carrier body 901 is mounted on the base 22 , and a height adjustment structure 23 for adjusting the height position of the carrier body 901 on the base 22 is provided between the base 22 and the mounting carrier 9 .

[0131] The base 22 provided here is the basic part for installing the carrier 9, which provides a stable installation foundation for the carrier body 901, and can be in the form of a flat plate, a frame, a column, etc.

[0132] The height adjustment structure 23 is an adjustment device disposed between the base 22 and the mounting carrier 9, and its main function is to adjust the height position of the carrier body 901 relative to the base 22. By introducing the base 22 and the height adjustment structure 23, the design of the mounting carrier 9 can be further improved, thereby improving the flexibility and adaptability of the mechanical structure, and also providing the possibility for its application in more complex and changeable working environments.

[0133] As in this embodiment, the height adjustment structure 23 specifically includes a plurality of connecting bolts and a plurality of adjustment bolts for connecting the carrier body 901 and the base 22. Each connecting bolt is inserted into a connecting hole on the carrier body 901 and the base 22, and the adjustment bolt is screwed on the carrier body 901 and tightened against the base 22, so that the height position of the installation carrier 9 can be adjusted by rotating the adjustment bolt.

[0134] It should be understood that the height adjustment structure 23 may adopt other structures besides the above structure, such as a spiral lift, a hydraulic lift, an electric lift, etc., depending on the application requirements, precision requirements and operational convenience.

[0135] The height adjustment structure 23 of this embodiment, combined with the use of the second position adjustment mechanism, enables the mounting carrier 9 to be accurately adjusted in multiple dimensions, thereby ensuring accurate connection with the door hanger 5 .

[0136] When using the driving mechanism of this embodiment, the driving mechanism can be moved to a suitable height position through the height adjustment mechanism 23 so that the pin pulling device can pull out the positioning pin, and the sixth driving unit 16 can drive the pin pulling device to a suitable position convenient for pin pulling, and the sixth driving unit 16 can drive the pin pulling device to swing the pin pulling device to a position that does not affect subsequent operations.

[0137] Through the second position adjustment mechanism, the driving mechanism can be driven to move to the transmission member 2 and the rotating member such as the door hanger to be plugged and connected. During the plugging process, the floating mechanism can effectively ensure the smooth progress of the plugging process. The transmission member 2 and the rotating member are plugged and connected and the two are coaxial. The transmission member 2 can be driven by the first driving member 6 to drive the door hanger to rotate. When used specifically, according to the use requirements, the second position adjustment mechanism and the first driving member 6 can be used to drive the door hanger to rotate multiple times. For example, the transmission member 2 of this embodiment can drive the door hanger to rotate 90° once, and can drive the door hanger to rotate 180° twice. It should be understood that the rotation angle can be controlled by the air pressure control mechanism 25, which can also be other values.

[0138] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
