[0030] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments disclosed in the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The present application embodiment discloses a self-propelled docking platform that takes into account the rolling docking function of cone-section products, such as Figure 1 As shown, it includes a first mobile platform 1 and a second mobile platform 2, and the first mobile platform 1 and the second mobile platform 2 are slidably connected to the surface of the self-propelled vehicle 4 along the same straight line direction.

[0032] like Figure 2 As shown, the first mobile platform and the second mobile platform have the same structure, and both include an upper enveloping ring 11, a lower enveloping ring 12, a rolling bracket 13, a rolling motor 14, and a posture adjustment mechanism 15. The posture adjustment mechanism 15 is slidably connected to the surface of the self-driving vehicle (the sliding direction is the X direction), and the rolling bracket 13 is connected above the posture adjustment mechanism 15. The posture adjustment mechanism 15 is used to drive the rolling bracket 13 to rise and fall in the vertical direction (Z direction), and to drive the rolling bracket 13 to move in the Y direction, and the Y direction is perpendicular to both the X direction and the Z direction. The upper enveloping ring 11 and the lower enveloping ring 12 are semicircular ring structures, and the open ends of the upper enveloping ring 11 and the lower enveloping ring 12 are detachably connected to form an annular rolling enveloping ring. The upper surface of the rolling bracket 13 is an arc surface, and an arc groove is provided on the upper surface of the rolling bracket 13, and the rolling enveloping ring is placed in the arc groove.

[0033] Three groups of rolling positioning devices 5 are connected to the middle of the arc groove of the rolling bracket 13. A rolling wheel mechanism 6 is arranged in the arc groove of the rolling bracket 13. The rolling wheel mechanism 6 includes an active rolling wheel 61 and a passive rolling wheel 62. The active rolling wheel 61 and the passive rolling wheel 62 are respectively located at the two ends of the three groups of rolling positioning devices 5. The outer circumferential surface of the rolling ring is a rolling surface, which contacts the rolling wheel mechanism 6 installed in the rolling bracket 3. The inner circumferential surface of the rolling ring is a supporting surface, which fits the external profile of the conical product. The rolling positioning device 5 contacts the two end faces of the rolling bracket 13 along its own axial direction, playing a guiding role. The connection method of the upper ring 11 and the lower ring 12 is plug-in plus screw connection plus pin positioning to ensure a tight connection without deviation. The key point of the rolling ring is that the center of the circle must be kept coincident with the theoretical center of mass of the product. Eccentricity will cause the rolling function to fail. The main view of the ring structure is shown in 2.

[0034] This patent is used for rolling docking of conical workpieces. The outer diameter and inner diameter of the rolling ring of the first mobile platform are smaller than the outer diameter and inner diameter of the rolling ring of the second mobile platform, so that the large end outer surface of the conical workpiece cooperates with the rolling ring of the second mobile platform, and the small end outer surface of the conical workpiece cooperates with the rolling ring of the first mobile platform.

[0035] Figure 4 It is a rolling positioning device 5, each group of rolling positioning devices 5 includes two positioning components, the two positioning components are respectively arranged at the two ends of the rolling bracket 13, each positioning component includes a positioning shell 51, a positioning bearing 52, a positioning shaft 53 and a fixing nut 54, the rolling bracket 13 is provided with a mounting hole, one end of the positioning shell 51 is connected to a convex edge, the positioning shell 51 passes through the mounting hole to the outside of the arc groove of the rolling bracket 13, the convex edge is clamped in the arc groove of the rolling bracket 13, and the convex edge and the rolling bracket 13 are fixedly connected by bolts; the end of the positioning shell 51 facing the arc groove is a mounting groove, the positioning shell 51 is provided with a mounting plate in the middle of the mounting groove, the positioning shaft 53 is fixed to the ring of the positioning bearing 52, the positioning shaft 53 passes through the mounting plate, and the fixing nut 54 is threadedly connected to the positioning shaft 53, so that the positioning shaft 53 and the positioning bearing 52 are installed on the mounting plate; the rotation axis of each positioning bearing 52 is along the radial direction of the arc groove of the rolling bracket 13. The outer ring of the locating bearing 52 faces the end face of the rolling ring. When the rolling ring contacts the locating bearing 52, the outer ring of the locating bearing 52 can rotate along with the rolling ring, so that the rolling process of the rolling ring is carried out along a fixed track without obvious shaking.

[0036] Figure 5The rolling wheel mechanism 6 includes an active rolling wheel 61 which is rotatably connected to the arc groove of the rolling bracket 13. The active rolling wheel 61 is connected to a rolling motor 14, which drives the active rolling wheel 61 to rotate. The passive rolling wheel 62 is rotatably connected to the arc groove of the rolling bracket 13. The rotation axes of the active rolling wheel 61 and the passive rolling wheel 62 are parallel to the rotation axis of the rolling ring in the arc groove. When the rolling ring is in the arc groove, the outer circumferential surface of the rolling ring contacts the outer circumferential surface of the active rolling wheel 61 and the passive rolling wheel 62, so that the rotation of the active rolling wheel 61 can drive the rolling ring to rotate. The middle part of the outer circumferential surface of the active rolling wheel 61 and the passive rolling wheel 62 is concave, presenting an annular groove. The rolling ring is located in the annular groove, which can further ensure that there is no risk of the ring tipping over during the rolling process.

[0037] There is a 0.5 mm gap between the inner side of the rolling support 13 and the end face of the rolling ring.

[0038] Figure 6 The in-place positioning device 7 is provided between the rolling ring and the rolling bracket 13. The in-place positioning device 7 includes a tensioning device and a first lug 75. The upper ring 11 and the lower ring 12 are each installed with four first lugs 75 of the in-place positioning device, that is, one first lug 75 is installed at each end of the two end faces of the upper ring 11, and one first lug 75 is installed at each end of the two end faces of the lower ring 12. Four tensioning devices are provided, and one tensioning device is connected to each end position of the two end faces of the rolling bracket 13. The tensioning device includes a pin 71, a nut 72, a first screw 73, a second screw 74 and a second ear 76. The second ear 76 is fixedly connected to the end face of the rolling bracket 13. The first screw 73 is connected to the second ear 76 through a pin. The nut 72 is sleeved on the first screw 73 and the second screw 74. The other end of the second screw 74 is detachably connected to the first ear 75 through the pin 71. When the nut 72 rotates, the distance between the first screw 73 and the second screw 74 increases or decreases. After the first ear of the upper wrapping ring 11 is connected and docked with the tensioning device, when other products need to be installed on the top of the rolling wrapping ring, the rolling wrapping ring is flipped 180° so that the first ear 75 of the lower wrapping ring 12 is connected to the tensioning device. The rolling wrapping ring can be positioned by flipping the rolling wrapping ring 180°. After the product is flipped, the tensioning device is connected to prevent the rolling wrapping ring from rolling.

[0039] Furthermore, the rolling bracket 13 of the second mobile platform is connected with a backstop mechanism 3 on the side facing away from the first mobile platform. The backstop mechanism 3 is used to resist the large end surface of the conical workpiece, thereby ensuring the position stability of the conical workpiece during the non-rolling process.

[0040] Figure 3As for the anti-retraction mechanism, the anti-retraction mechanism 3 includes a retraction bracket 31, a front section connecting seat 32, a rear section screw 33 and a hexagonal nut 34. The front section connecting seat 32 and the rear section screw 33 are welded and connected, and the front section connecting seat 32 is detachably connected to the rolling bracket 13. The retraction bracket 31 is sleeved on the outside of the rear section screw 33, and two hexagonal nuts 34 are threadedly connected to the rear section screw 33, and the two hexagonal nuts 34 are arranged on both sides of the retraction bracket 31. The retraction bracket 31 is clamped by the two hexagonal nuts 34 to achieve the function of preventing retraction and preventing disengagement. The position of the retraction bracket 31 in different states can be adjusted by rotating the hexagonal nut 34. In order to reduce its weight and facilitate manual disassembly and installation, the front section connecting seat 32 is in the form of thick-walled hollow.

[0041] The rolling of products with large tapers needs to consider the risk of the product falling off during the rolling process. Therefore, for products with large tapers and special-shaped surfaces, the docking trolley involved must not only realize the basic trolley function, but also ensure the safety of operation. Secondly, the combination of docking and rolling integrated trolleys requires precise layout in a limited space, and ensure that there is no interference between the various mechanisms, and the mechanism operation is convenient and labor-saving, without operational risks.

[0042] The rolling ring has a lifting hole for connecting the lifting ring separately, and can also be lifted and transported using two symmetrical weight-reducing holes. The upper and lower rings can independently support one side of the product, and the whole ring can be used to achieve operations such as rolling and flipping. The rolling ring accounts for nearly half of the weight of the frame, so it is equipped with a corresponding mechanism to solve the problem of fixing the ring and enhancing its rolling safety.

[0043] The characteristic of the docking and rolling integrated frame vehicle is that it saves the manufacturing cost of the flip sling. One set of integrated frame vehicles can meet the needs of front docking, flip docking, support parking, product flipping, etc. This frame vehicle is also transformable, and its main structure (flip ring) is a detachable and replaceable structure, which can be adapted to the assembly docking of similar products in the future.

[0044] In addition, the self-propelled vehicle at the bottom of the platform can transfer products to any designated location in the factory and can perform guided docking.

[0045] The contents not described in detail in this application specification belong to the common knowledge of those skilled in the art.

[0046] The present application is described in detail above in conjunction with specific implementation methods and exemplary examples, but these descriptions cannot be understood as limiting the present application. Those skilled in the art understand that, without departing from the spirit and scope of the present application, a variety of equivalent replacements, modifications or improvements can be made to the technical solution of the present application and its implementation methods, all of which fall within the scope of the present application. The scope of protection of the present application shall be subject to the attached claims.
