[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0024] like Figures 1-12As shown, a segmented chain-type rolling device includes a linear drive rolling limit block module 1, a rolling drive mechanism, and chain-type rolling limit blocks 2. The rolling drive mechanism includes a central rotating platform 4, a multi-faceted prism 401, and a motor 5. The output end of the motor 5 is fixed to the bottom of the central rotating platform 4, and the multi-faceted prism 401 is fixed to the top of the central rotating platform 4. The chain-type rolling limit block 2 is composed of multiple rolling limit blocks hinged together, and the first rolling limit block 201 of the chain-type rolling limit block 2 is fixed to one side of the multi-faceted prism 401.
[0025] The linear drive winding limit block module 1 drives the sliding rod 101 to move horizontally, and the end of the sliding rod 101 is fixed to the outer wall of the last winding limit block 202 of the chain winding limit block 2. Each winding limit block of the chain winding limit block 2 has a support mechanism 6 connected to its bottom.
[0026] Specifically, the linear drive rolling limit block module 1 is an existing structure, which can be a motor-driven screw. The screw passes through the movable seat and is threadedly connected to the movable seat, so that the movable seat can move along the guide rail. A sliding rod 101 is fixed on the movable seat.
[0027] The support mechanism 6 includes a connector 604, a column 601, a roller 602, and a connecting plate 603. The top of the column 601 is fixed to the bottom of the rolling limit block, and the connector 604 is fixed to the bottom of the column 601. The roller 602 is rotatably connected inside the connector 604, and the connecting plate 603 is also fixedly connected to the connector 604. The bottom of the roller 602 rotates on the support rod 11, and a connecting seat is fixedly connected to the bottom of the support rod 11.
[0028] Specifically, the support mechanism 6 ensures that the chain-type rolling limit block 2 can slide smoothly in both the straight section and the rolling section, with smooth movement and no jamming.
[0029] It also includes a base 3 12, on which a support column is fixedly connected. A base 2 9 is fixedly connected to the top of the support column, and a base 1 3 is fixedly connected to base 2 9. Two opposing linear slide rails 301 are fixedly connected to base 1 3, and a chain-type circular limiting block 2 is slidably connected to the slide rails 301. A circular through-slot is formed at the top of base 2 9, and a linear through-slot is formed on base 1 3. The linear through-slot is tangent to the circular through-slot, and the bottom of the chain-type circular limiting block 2 is located within both the linear and circular through-slots. The extension direction of the support rod 11 is consistent with the extension direction of the linear through-slot. The movement direction of the sliding rod 101 is also consistent with the extension direction of the linear through-slot.
[0030] The motor 5 in the rolling drive mechanism is fixed to the base 312. The polyhedron 401 is located in the circular through slot.
[0031] The base 312 is also equipped with a circular lifting mechanism 8, which includes a circular ring 7 and an electric cylinder. The electric cylinder is fixed on the base 312, and the movable end of the electric cylinder is fixed to the circular ring 7.
[0032] The ring 7 is a double-layered ring structure connected together, and the connecting plate 603 in the support mechanism 6 can be slidably connected in the double-layered ring 7. The support mechanism 6 at the bottom of the chain-type rolling limit block 2 can move between the support rod 11 and the ring 7. A notch is provided on the ring 7, located at one end of the support rod 11, and the support mechanism at the bottom of the chain-type rolling limit block 2 can transition between the support rod 11 and the ring 7.
[0033] Specifically, the outer edge of the connecting plate 603 is arc-shaped.
[0034] Each of the chain-type rolling limit blocks 2 has a groove on its top, and a segmented iron core 10 is limited in the groove. The segmented iron core 10 is higher than the rolling limit block, and the groove matches the outer dimensions of the segmented iron core 10.
[0035] Each of the chain-type circular limiting blocks 2 has a protrusion 203 on its inner wall, and a limiting groove is provided on one outer wall of the segmented iron core 10. The protrusion 203 cooperates with the limiting groove. The opposite inner wall of each circular limiting block is also provided with a positioning bead 204, and the positioning bead abuts against the other outer wall of the segmented iron core 10.
[0036] The number of faces of the polyhedron 401 and the number of rolled locating blocks are matched.
[0037] The linear drive winding limit block module 1 and the winding drive mechanism move synchronously.
[0038] The method of using this utility model is as follows: Step 1: Initially, the chain-type rolling limit block 2 is in a straight line shape. The rollers 602 in the support mechanism 6 at the bottom of a part of the rolling limit block are supported on the support rod 11. The connecting plate 603 on a part of the rolling limit block is set in the double-layered ring 7. The support rod 11 and the ring 7 play the role of supporting and guiding the chain-type rolling limit block 2.
[0039] Step two: Place the multiple segmented iron cores 10 into the grooves at the top of each of the chain-type rolling limiting blocks 2. During placement, the limiting groove on one side of the segmented iron core 10 engages with the protrusion 203 on the inner wall of the rolling limiting block, while the positioning bead 204 on the other inner wall of the rolling limiting block abuts against the other outer wall of the segmented iron core 10, thereby achieving positioning of the segmented iron core 10. The upper part of the segmented iron core 10 is higher than the rolling limiting block, making it easier for the robot arm to remove the rolled iron core.
[0040] Step 3: Start the motor 5 in the rolling drive mechanism and the motor in the linear drive rolling limit block module 1, and control them to maintain synchronous movement. Motor 5 drives the central rotating platform 4 to rotate, which in turn drives the multifaceted prism 401 to rotate. The multifaceted prism 401 pushes the first rolling limit block 201, which is fixed to it, to rotate. At the same time, the linear drive rolling limit block module 1 drives the sliding rod 101 to move horizontally forward, pushing the last rolling limit block 202 to move along the direction of the linear through groove.
[0041] Step four: Motor 5 in the rolling drive mechanism gradually rolls multiple rolling limit blocks of the chain-type rolling limit block 2 onto the polyhedron 401. After rolling is completed, the robot arm removes the rolled segmented iron core.
[0042] Step 5: The motor 5 and the linear drive rolling limit block module 1 in the rolling drive mechanism drive the chain rolling limit block 2 to reset to the initial state.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
