[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] The purpose of this invention is to provide a self-aligning physical diagnostic equipment tooling to solve the problems existing in the prior art. The main body of the equipment is transported by an automatic walking mechanism, and a synchronous locking mechanism locks it during the transport. After it is in place, the synchronous locking mechanism releases its degree of freedom, ensuring stable transportation without affecting the normal operation of the diagnostic equipment.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Please refer to the following: Figs. 1-7As shown, a self-aligning physical diagnostic equipment fixture is provided, including an automatic walking mechanism 1, a synchronous locking mechanism 2, and a main body 3. The synchronous locking mechanism 2 includes a lower support 12, a transition frame 13, an upper support 14, a drive motor 16, a lower lead screw 17, and an upper lead screw 21. The lower support 12, the transition frame 13, and the upper support 14 are all plate-shaped structures. The lower lead screw 17 is rotatably mounted on the lower support 12 via a bearing seat 38. The two ends of the lower lead screw 17 have threads with opposite directions. The two ends of the lower lead screw 17 are respectively threaded to a lower nut 18. The transition frame 13 is slidably mounted on the lower support 12 along the axial direction of the lower lead screw 17. The upper frame 13 is provided with a lower slide rail 20. The bottom of the transition frame 13 is provided with a groove that matches the lower slide rail 20. The groove is slidably disposed on the lower slide rail 20. The horizontal height of the lower surface of the transition frame 13 is lower than the horizontal height of the upper surface of the lower nut 18, so that when the two lower nuts 18 move towards each other, they can clamp and position the transition frame 13 along the axial direction of the lower lead screw 17. The upper lead screw 21 is rotatably disposed on the transition frame 13 through the bearing seat 38. The lower lead screw 17 and the upper lead screw 21 are connected to the drive motor 16. The upper lead screw 21 is perpendicular to the lower lead screw 17. The two ends of the upper lead screw 21 have threads with opposite directions. The two ends of the upper lead screw 21 are respectively threaded to the upper nut 22. The upper bracket 14 is slidably mounted above the transition frame 13 along the axial direction of the upper lead screw 21. Specifically, an upper slide rail 23 is provided on the upper surface of the transition frame 13, and a groove matching the upper slide rail 23 is provided at the bottom of the upper bracket 14. The groove slides on the upper slide rail 23. The lower surface of the upper bracket 14 is horizontally lower than the top of the upper nut 22, allowing the two upper nuts 22 to clamp and position the upper bracket 14 axially along the upper lead screw 21 when they move towards each other. The top of the upper bracket 14 is provided with a connecting part 15 that connects to the main body 3 of the equipment. By controlling the rotation direction of the drive motor 16, the two lower nuts 18 and the two upper nuts 22 can be controlled. The automatic walking mechanism 1 moves in opposite directions or in the opposite direction to lock and unlock the transition frame 13 and the upper bracket 14. During the process of the automatic walking mechanism 1 transferring the main body of the equipment 3, the synchronous locking mechanism 2 is kept in the locked state to stably transfer the main body of the equipment 3. After the main body of the equipment 3 is installed in place, the synchronous locking mechanism 2 is kept in the unlocked state to release the X and Y degrees of freedom, remove the restriction on the main body of the equipment 3, and disengage from the rigid connection with the main body of the equipment 3. This avoids affecting the adjustment accuracy of the diagnostic equipment and the deformation and vibration generated during the operation. At the same time, the automatic walking mechanism 1 is located below the main body of the equipment 3, making full use of the space below and reducing the occupation of the lateral space, which is suitable for transportation in complex environments.

[0035] Nut grooves 19 that match the nut can be provided on the lower bracket 12 and the transition bracket 13 to ensure the stable movement of the nut.

[0036] Since the height and posture of the main body 3 need to be adjusted when docking with the test device 4, the bottom of the lower bracket 12 is connected to the automatic walking mechanism 1 through the lifting electric cylinder 8. The lifting electric cylinder 8 can control the height of the main body 3. By setting several synchronous locking mechanisms 2, the docking posture of the main body 3 can be controlled by controlling the lifting height of different lifting electric cylinders 8.

[0037] A connecting sleeve is provided at the bottom of the lower bracket 12. The connecting sleeve is inserted into the rod of the telescopic end of the lifting electric cylinder 8 to ensure the stability of the connection between the two.

[0038] The connecting part 15 is a vertical connecting lug provided on both radial sides of the upper bracket 14 corresponding to the main body 3 of the equipment. The bottom of the main body 3 is provided with a protrusion for inserting between the two vertical connecting lugs. The bottom of the protrusion is semi-circular, and the thickness of the protrusion is the same as the distance between the two vertical connecting lugs. The protrusion and the vertical connecting lugs are provided with pin holes. The protrusion is connected to the connecting lug pin to ensure the connection. At the same time, the protrusion can rotate around the pin in the two connecting lugs to adjust the posture in conjunction with the lifting electric cylinder 8. A circular through hole is opened in the middle of the upper bracket 14 to avoid the rotation of the bottom of the protrusion.

[0039] One side of the main body 3 of the equipment is provided with an installation interface 5 for connecting to the test device 4. The installation interface 5 is provided with a connecting flange for bolting to the test device 4. The connecting flange is connected to the main body 3 of the equipment via a ball joint. Telescopic fine-tuning legs 6 are hinged to both radial sides of the end of the main body 3 away from the test device 4. The ends of the two telescopic fine-tuning legs 6 away from the main body 3 are both hinged to the support base plate. During transportation, the retraction of the telescopic fine-tuning legs 6 lifts the support base plate off the bottom surface to avoid affecting normal transportation. When the docking is completed and the posture of the main body 3 needs to be finely adjusted, the telescopic fine-tuning legs 6 are extended and the support base plate contacts the bottom surface to achieve support. At this time, the posture of the main body 3 can be finely adjusted by controlling the two telescopic fine-tuning legs 6 respectively. The telescopic fine-tuning legs 6 are preferably high-precision servo electric cylinders.

[0040] Because using two drive motors 16 to drive the upper lead screw 21 and the lower lead screw 17 respectively not only increases the number of drive motors 16 and the system weight, but also may result in different locking accuracies between the upper and lower lead screws, the lower lead screw 17 is designed with a smooth cylindrical shape in the middle. A keyway is provided axially in the middle of the lower lead screw 17, and a first bevel gear 24 is slidably fitted in the middle of the lower lead screw 17. The journal of the first bevel gear 24 has an opening that connects to the lower lead screw 17 via a guide transmission pin 28. This ensures that the transition frame 13 can be unlocked... In this state, it can move axially along the lower lead screw 17, and it can also ensure that the lower lead screw 17 transmits rotation to the first bevel gear 24. The outer circumference of the journal of the first bevel gear 24 is provided with a transmission pin retainer ring 33 to prevent the guide transmission pin 28 from falling out. The transmission pin retainer ring 33 is composed of two semicircles connected by bolts, which is convenient for installation. A corresponding stop can be set at the bottom of the transition frame 13 to restrict the axial movement of the transmission pin retainer ring 33 and prevent it from losing its ability to restrict the guide transmission pin 28. The middle of the upper lead screw 21 is provided with a fourth bevel gear 27, and the middle of the transition frame 13 is vertically connected. A through hole is provided, and a drive shaft 32 is installed in the through hole via a rolling bearing 34. The bottom of the drive shaft 32 is connected to the first bevel gear 24 via a second bevel gear 25, and the top is connected to the fourth bevel gear 27 via a third bevel gear 26. Both the second bevel gear 25 and the third bevel gear 26 are fixed to the drive shaft 32 by shaft end retaining rings 37. Vertical sleeves 35 are fitted on the outer walls of the drive shaft 32 on both sides corresponding to the rolling bearing 34. One end of the vertical sleeve 35 abuts against the inner ring of the rolling bearing 34, and the other end abuts against the second bevel gear 25 or the third bevel gear 26. The inner ring of the rolling bearing 34 is limited by a through hole with a variable diameter, including a large diameter section at the top and a small diameter section at the bottom. An elastic retaining ring 36 is embedded in the large diameter section. The elastic retaining ring 36 works with the step between the large and small diameter sections to limit the axial movement of the outer ring of the rolling bearing 34. The movement of the lower lead screw 17 is transmitted to the upper lead screw 21 by a mechanical structure to ensure the synchronization of their movements, thereby improving the accuracy of locking and unlocking. Moreover, only one drive motor 16 is needed to drive it, reducing the number of drive motors 16 used and reducing the overall weight of the equipment.

[0041] The lower lead screw 17 is slidably fitted with a first sleeve 29 and a second sleeve 30 on both sides of the first bevel gear 24. The transition frame 13 is provided with bearing seats 38 at the positions corresponding to the first sleeve 29 and the second sleeve 30. Bearings are provided between the bearing seats 38 and the first sleeve 29 and between the bearing seats 38 and the second sleeve 30. The bearings can be rolling bearings 34. The first sleeve 29 and the second sleeve 30 provide the mounting base for the bearings, which improves the movement stability of the lower lead screw 17 and ensures the relative sliding between the transition frame 13 and the lower support frame 12.

[0042] To further improve the stability of the movement of the lower lead screw 17, an annular protrusion is provided on the lower lead screw 17. The lower bracket 12 is provided with axial limiting blocks 31 on both sides of the annular protrusion. The axial limiting blocks 31 can be block-shaped structures to block the annular protrusion from both sides, or the axial limiting blocks 31 on both sides can be set as an integral structure to form a cavity that matches the annular protrusion. The cavity has through holes on both sides that match the lower lead screw 17. Similarly, the upper lead screw 21 is also provided with an annular protrusion and axial limiting blocks 31 for axial limiting.

[0043] The automatic walking mechanism 1 includes a frame 7 and a walking wheel set at the bottom of the frame 7. The frame 7 has a hollow structure to reduce the weight of the vehicle body. At the same time, the walking wheel is set as an AGV steering wheel 9, which can realize the function of automatic walking.

[0044] Several support rods 10 are hinged around the frame 7. An adjusting rod 11 is vertically threaded to the end of the support rod 10 away from the frame 7. An anti-slip pad is provided at the bottom of the adjusting rod 11. When the automatic walking mechanism 1 is in position, the anti-slip pad can be made to contact the ground by unscrewing the support rod 10 and rotating the adjusting rod 11 downward. This not only ensures the stability of the automatic walking mechanism 1, but also releases the load on the AGV steering wheel 9 and improves its service life.

[0045] The AGV steering wheel 9, lifting electric cylinder 8, drive motor 16, and telescopic fine-tuning outrigger 6 all use electricity as the driving energy. Corresponding power supplies and control systems are set on the frame 7. The control system is connected to the control terminal via a wireless module and can control the movement of each component through the control terminal.

[0046] In practical use, the synchronous locking mechanism 2 is used to lock the main body 3 of the equipment. The AGV steering wheel 9 is controlled to drive the entire equipment to the test device 4. The attitude of the main body 3 of the equipment is adjusted by the AGV steering wheel 9 and the lifting electric cylinder 8 so that the installation interface 5 of the main body 3 corresponds to the interface of the test device 4. The AGV steering wheel 9 is controlled to drive the entire equipment forward to connect the two interfaces. After connection, the connecting flange is manually connected with bolts. After connection, the synchronous locking mechanism 2 is controlled to be in the unlocked state, and the lifting electric cylinder 8 is controlled to retract downwards and wait. During the next transfer, since the connecting lug of the synchronous locking mechanism 2 is still connected to the main body of the equipment 3, the retraction of the lifting electric cylinder 8 is manifested as the downward movement of the telescopic end rod within the connecting sleeve (during the downward retraction of the lifting electric cylinder 8, the telescopic end rod does not detach from the connecting sleeve). At this time, the synchronous lock and mechanism 2 can still slide up and down on the telescopic end rod of the lifting electric cylinder 8 through the connecting sleeve, providing movement space for subsequent attitude fine-tuning. After the lifting electric cylinder 8 has retracted downward, the attitude fine-tuning of the main body of the equipment 3 can be completed by controlling the two telescopic fine-tuning legs 6.
