Description

Technical Field

[0001] This utility model relates to the field of warehousing material transportation equipment, and in particular to a bidirectional double-stroke transfer device. Background Technology

[0002] In machining parts storage systems, loading, unloading, and transfer of stored parts are required to complete various processing steps, necessitating the use of transfer equipment during transportation. The main problems with existing automated transfer equipment are: If the length of the automatic support device is too short, it cannot stably load large workpieces and tooling, or reach the accurate support position; while if the length is too long, it increases the space required for movement, thus increasing the storage system's floor space cost, and may also interfere with or collide with the racks during loading, reducing system safety. Furthermore, in large-capacity storage rack structures, as the length and height of the racks increase, the racks, due to increased weight and a shift in the center of gravity, may experience unpredictable deflection and swaying. This causes the actual position of the workpieces and tooling to be loaded to not perfectly match the predetermined position, resulting in low loading accuracy and a significantly increased frequency of collisions. Utility Model Content

[0003] This utility model aims to solve the above problems and provides a bidirectional, dual-stroke transfer device, the technical solution of which is as follows: A bidirectional, double-stroke transfer device includes a fixed connecting frame, a primary sliding frame, and a secondary sliding frame. The upper surface of the secondary sliding frame is flat. A primary drive gear is rotatably connected to the fixed connecting frame, and the primary drive gear rotates in a vertical plane. A primary rack is fixedly connected to the primary sliding frame facing the fixed connecting frame, and the primary rack extends along the moving direction of the primary sliding frame, with the primary drive gear meshing with the primary rack. A secondary drive gear is rotatably connected to the primary sliding frame, and the secondary drive gear rotates in a vertical plane. A secondary rack is fixedly connected to the secondary sliding frame facing the primary sliding frame, and the secondary rack is parallel to the primary rack and extends along the moving direction of the secondary sliding frame, with the secondary drive gear meshing with the secondary rack.

[0004] Based on the above scheme, the fixed connecting frame includes two vertically arranged and relatively parallel connecting plates, a primary drive gear is connected between the two connecting plates, a primary sliding frame is arranged above the fixed connecting frame, the primary sliding frame extends downward in the outer area of ​​the fixed connecting frame and bends to form a primary sliding groove, a connecting frame pulley is rotatably arranged on the fixed connecting frame in the horizontal direction, the connecting frame pulley rotates in the vertical plane, the connecting frame pulley is arranged on the opposite outer side of the connecting plate, and the connecting frame pulley is rotatably engaged in the primary sliding groove.

[0005] Based on the above scheme, there are multiple connecting frame pulleys on each side connecting plate, and they are arranged in a direction parallel to the first-stage rack.

[0006] Preferably, the secondary sliding frame is disposed above the primary sliding frame, and the bottom of the secondary sliding frame is fixedly connected to the secondary connecting frame in the outer area of ​​the primary sliding frame. The secondary connecting frame is rotatably connected to the secondary pulley, which rotates in the vertical plane. The primary sliding frame is recessed inward on the side facing the secondary connecting frame to form a secondary sliding groove, and the secondary pulley is rotatably engaged in the secondary sliding groove.

[0007] Based on the above scheme, the secondary connecting frame and the secondary sliding groove are respectively set on both sides of the secondary sliding frame and the primary sliding frame. The number of secondary pulleys connected on each side of the secondary connecting frame is multiple, and they are arranged in a direction parallel to the secondary rack.

[0008] Preferably, a supporting pulley is rotatably connected to the outer side of the primary sliding frame. The supporting pulley rotates in a vertical plane, and its upper part abuts against the lower edge of the secondary connecting frame and rotates relative to the secondary connecting frame. A limiting pulley is rotatably connected to the lower edge of the secondary connecting frame. The limiting pulley rotates in a horizontal plane, and its side near the primary sliding frame abuts against the outer edge of the primary sliding frame and rotates relative to the primary sliding frame.

[0009] Preferably, there are multiple primary drive gears arranged in a direction parallel to the primary rack, with adjacent primary drive gears meshing with each other, and each primary drive gear meshing with the primary rack; there are two secondary drive gears, located at opposite corners of the primary sliding frame.

[0010] Preferably, a primary drive motor is connected to the fixed connecting frame, and the primary drive motor drives the primary drive gear to rotate; a secondary drive motor is connected to the primary sliding frame, and the secondary drive motor drives the secondary drive gear to rotate; it also includes a distance sensor, the distance sensor being fixed in relative position to the fixed connecting frame, and the distance sensor being communicatively connected to the primary drive motor and the secondary drive motor.

[0011] Preferably, it further includes a horizontal transfer guide rail, a vertical transfer guide rail, and a movable frame. The horizontal transfer guide rail is arranged in a horizontal plane, the vertical transfer guide rail is arranged in a vertical direction, and the vertical transfer guide rail is slidably arranged on the horizontal transfer guide rail. The movable frame is slidably arranged on the vertical transfer guide rail, and the fixed connecting frame is fixedly connected to the movable frame. The extension direction of the horizontal transfer guide rail is perpendicular to the extension direction of the first-stage rack in the horizontal plane.

[0012] The beneficial effects of this utility model are as follows: The two-stage sliding mechanism satisfies two different transport needs: short-distance small-sized workpieces and long-distance large-sized workpieces. When transporting short-distance or small-sized workpieces and tooling, only the second-stage or first-stage sliding frame moves. When transporting long-distance or large-sized workpieces and tooling, both the first-stage and second-stage sliding frames extend together, effectively doubling the stroke of the bearing device based on the fixed connecting frame, thus meeting the needs of different sizes and transport distances. The two-stage gear structure not only meets the bidirectional movement requirements, enabling direct bidirectional transport of workpieces and tooling, but also allows for precise stepless control of the sliding frame extension distance according to actual distance requirements. The multi-pulley structure reduces friction between the sliding frames during relative movement and increases support stability during the receiving and transport process.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0017] like Figures 1 to 3 As shown, a bidirectional double-stroke transfer device includes a fixed connecting frame 461, a primary sliding frame 471 and a secondary sliding frame 481. The upper surface of the secondary sliding frame 481 is flat and is used to support workpieces or tooling.

[0018] A primary drive gear 462 is rotatably connected to the fixed connecting frame 461. The primary drive gear 462 rotates in a vertical plane. A primary sliding frame 471 is fixedly connected to a primary rack 472 on the side facing the fixed connecting frame 461. The primary rack 472 extends along the moving direction of the primary sliding frame 471, and the primary drive gear 462 meshes with the primary rack 472. The rotation of the primary drive gear 462 drives the primary rack 472 and the primary sliding frame 471 to move relative to the fixed connecting frame 461. Preferably, there are multiple primary drive gears 462, arranged parallel to the primary rack 472, with adjacent primary drive gears 462 meshing with each other. Each primary drive gear 462 meshes with the primary rack 472, improving driving capability and supporting the primary sliding frame 471 at different positions.

[0019] A secondary drive gear 473 is rotatably connected to the primary sliding frame 471. The secondary drive gear 473 rotates in a vertical plane. A secondary rack (not shown in the figure) is fixedly connected to the secondary sliding frame 481 facing the primary sliding frame 471. The secondary rack is parallel to the primary rack 472 and extends along the moving direction of the secondary sliding frame 481. The secondary drive gear 473 meshes with the secondary rack. The rotation of the secondary drive gear 473 drives the secondary rack and the secondary sliding frame 481 to move relative to the primary sliding frame 471. There are two secondary drive gears 473, which are located diagonally opposite each other on the primary sliding frame 471. Correspondingly, there are also two secondary racks to balance the supporting force of the secondary drive gears 473 on the secondary sliding frame 471.

[0020] Preferably, the fixed connecting frame 461 includes two vertically arranged and relatively parallel connecting plates. A primary drive gear 462 is connected between the two connecting plates. A primary sliding frame 471 is arranged above the fixed connecting frame 461. The primary sliding frame 471 extends downward in the outer region of the fixed connecting frame 461 and is bent to form a primary sliding groove. The primary sliding groove is a U-shaped groove that opens to one side of the connecting plate. A connecting frame pulley 464 is rotatably arranged on the fixed connecting frame 461 in the horizontal direction. The connecting frame pulley 464 rotates in the vertical plane and is arranged on the opposite outer side of the connecting plate. The connecting frame pulley 464 is rotatably engaged in the primary sliding groove. On the one hand, it supports the primary sliding frame 471, and on the other hand, it modifies the sliding friction between the primary sliding frame 471 and the fixed connecting frame 461 into rolling friction, which greatly reduces the frictional resistance. Preferably, there are multiple connecting frame pulleys 464 on each side connecting plate, and they are arranged in a direction parallel to the first-stage rack 472 to provide uniform support for different positions of the first-stage sliding frame 471.

[0021] Preferably, the secondary sliding frame 481 is disposed above the primary sliding frame 471. The bottom of the secondary sliding frame 481 is fixedly connected to the secondary connecting frame 482 in the outer region of the primary sliding frame 471. The secondary connecting frame 482 is rotatably connected to the secondary pulley 483, which rotates in the vertical plane. The primary sliding frame 471 is recessed inward on the side facing the secondary connecting frame 482 to form a secondary sliding groove. The secondary sliding groove is a U-shaped groove with a horizontally outward opening. The secondary pulley 483 is rotatably engaged in the secondary sliding groove, which on the one hand supports the secondary sliding frame 481, and on the other hand modifies the sliding friction between the secondary sliding frame 481 and the primary sliding frame 471 into rolling friction, greatly reducing frictional resistance. Preferably, the secondary connecting frame 482 and the secondary sliding groove are respectively arranged on both sides of the secondary sliding frame 481 and the primary sliding frame 471. Multiple secondary pulleys 483 are connected to each secondary connecting frame 482 and arranged in a direction parallel to the secondary rack. This is used to evenly support different positions of the secondary sliding frame 481.

[0022] The outer side of the primary sliding frame 471 is rotatably connected to a supporting pulley 474, which rotates in a vertical plane. The upper part of the supporting pulley 474 abuts against the lower edge of the secondary connecting frame 482 and rotates relative to the secondary connecting frame 482, thereby supporting the secondary connecting frame 482 and the secondary sliding frame 481 and reducing friction. The lower edge of the secondary connecting frame 482 is rotatably connected to a limiting pulley 484, which rotates in a horizontal plane. The side of the limiting pulley 484 near the primary sliding frame 471 abuts against the outer edge of the primary sliding frame 471 and rotates relative to the primary sliding frame 471, thereby limiting the relative positional relationship between the secondary sliding frame 481 and the primary sliding frame 471.

[0023] A primary drive motor 463 is connected to the fixed connecting frame 461, which drives a primary drive gear 462 to rotate. A secondary drive motor is connected to the primary sliding frame 471, which drives the secondary drive gear 473 to rotate. A distance sensor 44 is also included, which is fixed in position relative to the fixed connecting frame 461 and is communicatively connected to both the primary and secondary drive motors. The distance sensor 44 detects the actual distance between the fixed connecting frame 461 and the position to be supported. Based on the detection result, the primary and secondary drive motors are controlled to operate, further controlling the extension direction and distance of the primary and secondary sliding frames 471 and 481 to meet the actual support position and distance requirements.

[0024] Preferably, the system further includes a horizontal transfer guide rail 41, a vertical transfer guide rail 42, and a movable frame 43. The horizontal transfer guide rail 41 is arranged in a horizontal plane, the vertical transfer guide rail 42 is arranged in a vertical direction and is slidably mounted on the horizontal transfer guide rail 41, and the movable frame 43 is slidably mounted on the vertical transfer guide rail 42. A fixed connecting frame 461 is fixedly connected to the movable frame 43. The extension direction of the horizontal transfer guide rail 41 is perpendicular to the extension direction of the first-stage rack 472 in the horizontal plane. By setting the transfer guide rails, the movable frame 43 can drive the fixed connecting frame 461 to move over a wide range in space, thereby enabling material transfer at different locations.

[0025] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
