[0004] However, the aforementioned publicly available solutions have the following shortcomings: the existing automatic assembly equipment for gear reducers requires workers to install the reducers into specific positions for assembly, which is inefficient and cannot realize an automated production line. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that gearboxes cannot be automatically transported and installed, and to propose an automatic gearbox assembly device.

[0006] The technical solution of this utility model: an automatic assembly device for gear reducers, comprising a mounting frame, a support frame disposed on the side of the mounting frame, and a conveying roller disposed on the top of the support frame; further comprising:

[0007] The centering adjustment mechanism is located at the bottom of the mounting frame and is used to center and clamp gearboxes of different sizes.

[0009] The partition plate has a fixed shaft rotatably mounted on its inner side. The bottom of the fixed shaft is connected to the top of the mounting frame. A photosensitive switch is mounted on the partition plate, and a controller is mounted on the back of the partition plate. The limit mechanism drives the partition plate to rotate intermittently. When the partition plate rotates to a position perpendicular to the conveyor roller, it stops the gearbox. At the same time, the gearbox covers the photosensitive switch, thereby controlling the controller to open. The controller controls the centering adjustment mechanism to open.

[0027] Example 1

[0028] like Figures 1-5As shown, the present invention proposes an automatic assembly equipment for gear reducers, including a mounting frame 1, a support frame 2 disposed on the side of the mounting frame 1, a conveying roller 3 disposed on the top of the support frame 2, a centering adjustment mechanism, a limiting mechanism, and a baffle plate 707. There are two support frames 2 symmetrically arranged about the mounting frame 1. The conveying roller 3 is used to place the gear reducer and convey the gear reducer.

[0029] The centering adjustment mechanism is located at the bottom of the mounting bracket 1 and is used to center and clamp gearboxes of different sizes;

[0030] The limiting mechanism is located on the top of the mounting bracket 1 and is used to intermittently limit the gearbox.

[0031] A fixed shaft 708 is rotatably mounted on the inner side of the baffle 707. The bottom of the fixed shaft 708 is connected to the top of the mounting bracket 1. A photosensitive switch 709 is mounted on the baffle 707. A controller 710 is mounted on the back of the baffle 707. The limiting mechanism drives the baffle 707 to rotate intermittently. When the baffle 707 rotates to a position perpendicular to the conveyor roller 3, it stops the reduction gearbox. At the same time, the reduction gearbox covers the photosensitive switch 709, thereby controlling the controller 710 to open. The controller 710 controls the centering adjustment mechanism to open.

[0032] The mounting frame 1 has a top plate 4 on top and a robotic arm 5 at the bottom of the top plate 4. The robotic arm 5 is used to automatically install the components inside the gear reducer.

[0033] The limiting mechanism includes a fixed frame 701, a second cylinder 702, a second push rod 703, and a push block 704. The fixed frame 701 is located on the top of the mounting bracket 1, the second cylinder 702 is located inside the fixed frame 701, the second push rod 703 is located at the output end of the second cylinder 702, and the push block 704 is rotatably located at the end of the second push rod 703 away from the second cylinder 702.

The inner side of the guide groove 706 is slidably connected to the push block 704. When the cylinder 702 is activated, the cylinder 702 drives the push rod 703 to move intermittently back and forth. The push rod 703 drives the push block 704 to move. When the push block 704 moves, it drives the rotating plate 705 to rotate through the guide groove 706. The top of the rotating plate 705 is connected to the bottom of the baffle plate 707, so they rotate synchronously, thereby causing the baffle plate 707 to rotate to a position perpendicular to the conveyor roller 3 to limit the gearbox.

[0034] Example 2

[0035] like Figures 2-3 As shown, the present invention proposes an automatic assembly device for gear reducers. Compared with Embodiment 1, this embodiment details the structure of the centering adjustment mechanism.

[0036] The centering adjustment mechanism includes a centering component and an adjustment component. The centering component is located on the top of the mounting frame 1 and is used to drive the adjustment component to move for centering. The adjustment component is located on the top of the centering component and is used to adjust the centering movement distance according to the gearbox of different sizes and to clamp the gearbox for centering. The centering component includes a cylinder 601, a push rod 602, a mounting plate 603, and a fixing block 604. The cylinder 601 is located at the bottom of the mounting frame 1, the push rod 602 is located at the output end of the cylinder 601, the mounting plate 603 is located on the top of the push rod 602, and the fixing block 604 is located on the top of the mounting plate 603. The cylinder 601 drives the push rod 602 to move, the push rod 602 drives the mounting plate 603 to move, and the mounting plate 603 drives the rotating rods 605 on both sides to rotate synchronously through the fixing block 604. The rotating rods 605 drive the centering plate 615 to move through the sliding rod 612 and the fixed platform 613. The adjustment assembly includes a sliding rod 612, a rotating rod 605, a fixed platform 613, a slide bar 611, a connecting frame 610, a motor 609, and a rotating shaft 608. The rotating rod 605 is rotatably mounted inside the fixed block 604, the sliding rod 612 is slidably mounted inside the rotating rod 605, the fixed platform 613 is rotatably mounted at the end of the sliding rod 612 away from the rotating rod 605, the fixed platform 613 has a sliding groove, a sliding plate 614 is slidably mounted inside the groove, a centering plate 615 is mounted at the end of the sliding plate 614, the slide bar 611 is mounted outside the rotating rod 605, the connecting frame 610 is slidably mounted on the slide bar 611, and the motor 609... Located on the side of the connecting frame 610 away from the slide bar 611, the rotating shaft 608 is located at the output end of the motor 609. A spur gear 607 is provided on the outer side of the rotating shaft 608, and a rack 606 meshes with the outer side of the spur gear 607. The side of the rack 606 is connected to the side of the rotating rod 605. The outer side of the rotating shaft 608 is rotatably connected to the inner side of the sliding rod 612. The motor 609 drives multiple spur gears 607 to rotate through the rotating shaft 608. The spur gears 607 roll on the rack 606, thereby driving the sliding rod 612 to slide on the rotating rod 605. Thus, the overall length of the sliding rod 612 and the rotating rod 605 is adjusted according to the width of the gearbox.

[0037] In summary, when using this utility model, the motor 609 is started, and the motor 609 drives multiple spur gears 607 to rotate via the rotating shaft 608. The spur gears 607 roll on the rack 606, thereby causing the sliding rod 612 to slide on the rotating rod 605. The overall length of the sliding rod 612 and the rotating rod 605 is then adjusted according to the width of the gearbox. When a wider gearbox needs to be clamped, the spur gears 607 drive the sliding rod 612 to move outward, increasing the overall length; conversely, the opposite is true. After adjustment, the gearboxes are placed equidistantly on the conveying roller 3. When the conveying roller 3 moves the gearboxes to the robotic arm 5, the cylinder 702 drives the push rod 703 to move, and the push rod 703 drives the push block 704 to move. When 704 moves, it drives the rotating plate 705 to rotate through the guide groove 706. The rotating plate 705 drives the baffle plate 707 to rotate to a position perpendicular to the conveyor roller 3 to limit the gearbox. At the same time, the gearbox covers the photosensitive switch 709, thereby controlling the controller 710 to open. The controller 710 controls the cylinder 601 to start. The cylinder 601 drives the push rod 602 to move. The push rod 602 drives the mounting plate 603 to move. The mounting plate 603 drives the rotating rods 605 on both sides to rotate synchronously through the fixing block 604. The rotating rods 605 drive the centering plate 615 to move through the sliding rod 612 and the fixed platform 613, thereby centering and clamping the gear reducer. After clamping, the robotic arm 5 performs automatic assembly.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
