Description

Technical Field

[0001] This utility model relates to the field of workpiece assembly technology, and specifically to a steering and conveying mechanism. Background Technology

[0002] With the rapid development of my country's equipment manufacturing industry, enterprises have increasingly higher demands for mechanical automation in production. In automated production lines, it is often necessary to transfer workpieces from one station to another for assembly. Electric rotary grippers are usually used. During the assembly process, the rotating electric grippers can only change the orientation of the workpiece. This is obviously unsuitable for assembling workpieces that are not on the same plane. For example, if the planes of the two workpieces are perpendicular, the rotating electric grippers need to be rotated 90° to transfer them to the other station for alignment with the workpiece and assembly. Therefore, there is an urgent need for a structure that can rotate the gripping components and move the workpiece to another station. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a steering and conveying mechanism that can solve the problem of assembling two workpieces on different planes.

[0004] To achieve the above technical objectives, this utility model proposes the following technical solution: a steering and conveying mechanism, comprising a worktable, a moving mechanism, and a cylinder rotatably mounted on top of the moving mechanism. An L-shaped support rod is fitted inside the cylinder, and a rotating electric gripper is provided at the end of the L-shaped support rod away from the cylinder. A groove is provided on the outer wall of the cylinder, and a roller is provided in the groove. The moving mechanism includes two upright plates, a guide rod fixed between the two upright plates, and a sliding plate slidably mounted on the guide rod. A slide rail is installed on the top of the sliding plate, and a slider is provided in the slide rail. The slider and the roller are connected by a sleeve. A rotating shaft is installed on the sliding plate. When the rotating shaft rotates, it can cause the L-shaped support rod to turn. When the rotating shaft is stationary, it can cause the L-shaped support rod to move.

[0005] Furthermore, a spring is provided inside the sleeve, and the rotation shaft of the roller is installed inside the sleeve via the spring.

[0006] Furthermore, a rack is provided on one side of the slider, and a gear that meshes with the rack is provided at one end of the rotating shaft.

[0007] Furthermore, a worm gear is installed at the other end of the rotating shaft through the sliding plate, and a worm gear meshing with the worm gear is provided between the two upright plates and on both sides of the worm gear. A motor for driving the worm gear to rotate is provided at either end of the worm gear.

[0008] Furthermore, the number of guide rods is no less than two.

[0009] Furthermore, the projected length of the groove is 1 / 4 of the outer circumference of the top of the cylinder.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the utility model has a simple structure and is easy to operate. The rotation direction of the two worm gears is controlled by the motor, which drives the worm wheel to rotate or move, thereby providing power for the movement and steering of the rotary electric gripper; the roller is indirectly driven to slide in the slide groove through the rack, thereby realizing the steering of the rotary electric gripper, which facilitates the assembly of two workpieces on different planes and realizes the cyclic operation, achieving the purpose of automated production.

[0015] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1-3 As shown, this utility model provides a steering and conveying mechanism, including a workbench 1, a moving mechanism 2, and a cylinder 3 rotatably mounted on top of the moving mechanism 2. An L-shaped support rod 4 is fixedly fitted inside the cylinder 3. A rotating electric gripper 5 is provided at the end of the L-shaped support rod 4 away from the cylinder 3. A sliding groove 6 is provided on the outer wall of the cylinder 3, and a roller 7 is provided in the sliding groove 6. The moving mechanism 2 includes two upright plates 21 fixed on the workbench 1, a guide rod 22 fixed between the two upright plates 21, and a sliding plate 23 slidably mounted on the guide rod 22. A slide rail 8 is installed on the top of the sliding plate 23, and a slider 9 is provided in the slide rail 8. The slider 9 is connected to the roller 7 through a sleeve 10. The number of guide rods 22 is not less than two, which can maintain the stability of the sliding plate 23 sliding on the guide rod 22. A rotating shaft 24 is installed on the sliding plate 23. When working, the rotating shaft 24 can cause the L-shaped support rod 4 to turn when it rotates, and can cause the L-shaped support rod 4 to move when the rotating shaft 24 is stationary.

[0017] like Figure 1As shown, when the slider 9 slides within the slide rail 8, the slider 9 will drive the roller 7 to move linearly along the direction of the slide rail 8. When the roller 7 moves, it can drive the cylinder 3 to rotate. The cylinder 3 drives the rotating electric gripper 5 to rotate around one end of the cylinder 3 at a certain angle. The angle of rotation of the cylinder 3 is determined by the slide groove 6. In use, the rotating electric gripper 5 first clamps the workpiece. When the roller 7 slides to the left along the direction of the slide rail 8, it drives the cylinder 3 to rotate at a certain angle. When the roller 7 slides to the right along the direction of the slide rail 8, it drives the cylinder 3 to rotate in the opposite direction at a certain angle, returning to the starting position, thus realizing the reciprocating rotation of the electric gripper 5.

[0018] The sleeve 10 is equipped with a spring 11, and the rotation shaft of the roller 7 is installed inside the sleeve 10 through the spring 11.

[0019] like Figure 2 and 3 As shown, under the action of the spring 11, the roller 7 extends and retracts in the sleeve 10, which can prevent the roller 7 from making hard contact with the slider 9 and reduce the impact of the roller 7 on the inner wall of the groove 6.

[0020] A rack 12 is provided on one side of the slider 9, and a gear 13 that meshes with the rack 12 is provided at one end of the rotating shaft 24.

[0021] like Figure 3 As shown, rack 12 is slidably installed in slide rail 8. When rotation 24 rotates, it drives gear 13 to rotate. The rotation of gear 13 drives rack 12 to move along slide rail 8. Rack 12 will drive slider 9 to slide, realizing the movement of roller 7.

[0022] The other end of the rotating shaft 24 passes through the slide plate 23 and is equipped with a worm gear 25. Between the two upright plates 21 and on both sides of the worm gear 25, there is a worm 26 that meshes with the worm gear 25. A motor 27 that drives the worm 26 to rotate is provided at any end of the worm 26.

[0023] like Figure 1 and 2 As shown, when the motor 27 drives the two worm gears 26 to rotate in the same direction, the worm wheel 25 does not rotate, and the slide plate 23 moves back and forth, causing the rotating electric gripper 5 to move. When the motor 27 drives the two worm gears 26 to rotate in different directions, the worm wheel 25 will rotate but will not move back and forth, causing the gear 13 to rotate. The rotation of the gear 13 will cause the rack 12 to move along the slide rail 8, and the rack 12 will cause the slider 9 to move, thereby realizing the rotation of the cylinder 3.

[0024] The projected length of the groove 6 is 1 / 4 of the outer circumference of the top of the cylinder 3.

[0025] like Figure 1 As shown, the rotation angle of the L-shaped support rod 4 is determined according to the projected length of the slide groove 6. In this embodiment, the cylinder 3 rotates 90° in one operation.

[0026] Operating principle: In operation, the rotating electric gripper 5 picks up the workpiece. The motor 27 is started, initially driving the two worm gears 26 to rotate in opposite directions. The worm wheel 25 rotates but does not move back and forth. The rotation of the worm wheel 25 causes the gear 13 to rotate, which in turn drives the rack 12 to move along the slide rail 8. The rack 12 then drives the slider 9 to slide, which in turn drives the roller 7 to move linearly along the slide rail 9. Since the cylinder 3 is rotatably mounted on the slide plate 23, the roller 7 slides within the groove 6, causing the cylinder 3 to rotate. The cylinder 3 then drives the rotating electric gripper 5 at the end of the L-shaped support rod 4 to rotate. After the rotation, the motor 27 then drives the two worm gears 26 to rotate in the same direction, while the worm wheel 25 remains stationary. The slide plate 23 moves forward, driving the rotary electric gripper 5 to move to another workstation for assembling the workpiece. The rotary electric gripper 5 drives the workpiece to complete the assembly with the workpiece at the other workstation. After assembly, the motor 27 drives the two worm gears 26 to rotate in the same direction. The direction of rotation of the worm gears 26 is opposite to the direction in which the slide plate 23 moves forward. The slide plate 23 moves backward, driving the rotary electric gripper 5 to move away from the other workstation. Finally, the motor 27 drives the two worm gears 26 to rotate in different directions. At this time, the direction of rotation of the worm wheel 25 is opposite to the direction of rotation of the worm wheel 25 mentioned above, driving the cylinder 3 to rotate in the opposite direction, restoring the cylinder 3 to its original position. This cycle repeats to achieve the assembly of the workpiece.
