Description

Technical Field

[0001] This utility model relates to the field of flipping structures, and in particular to a workpiece flipping mechanism for a sleeve machine. Background Technology

[0002] A sleeve fitting machine is a device used to fit two pipes or a pipe to a fitting. The pipes or fittings are cylindrical workpieces. During the transport process by the conveyor trolley, the central axis of the workpiece is usually vertical. The weight of the pipes or fittings is usually relatively heavy, so a flipping mechanism is needed to flip the workpiece 90° so that the central axis of the workpiece becomes horizontal.

[0003] Traditional flipping mechanisms are mostly driven by motors. The flipping platform is L-shaped, and the output shaft of the motor is fixedly connected to the corner of the flipping platform. When the output shaft of the motor rotates, it controls the flipping platform to flip. However, when flipping heavy workpieces, the torque required by the motor is very large, which leads to unstable flipping. Therefore, a flipping mechanism with improved stability is needed. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a workpiece flipping mechanism for a sleeve-making machine.

[0005] The technical solution of the workpiece flipping mechanism for a sleeve-making machine provided in this application is as follows:

[0006] A workpiece flipping mechanism for a sleeve-making machine includes a flipping platform and a drive assembly. The flipping platform is L-shaped and includes a first plate and a second plate fixedly connected. Before flipping, the first plate is horizontal and the second plate is vertical. After flipping, the first plate is vertical and the second plate is horizontal.

[0007] A support frame is provided on the ground, and a rotating shaft is provided at the end of the second plate away from the first plate. The rotating shaft is rotatably connected to the support frame through a bearing seat.

[0008] The drive assembly includes a cylinder and a transmission plate. An auxiliary frame is provided on the ground. The cylinder is mounted on the auxiliary frame, and the transmission plate is slidably mounted on the auxiliary frame. One end of the transmission plate is rotatably connected to the piston rod of the cylinder, and the other end of the transmission plate is rotatably connected to a second plate. The auxiliary frame is provided with a limiting component for limiting the end of the transmission plate away from the flipping platform. The limiting component keeps the end of the transmission plate away from the flipping platform sliding along the length direction of the auxiliary frame.

[0009] The distance between the position where the transmission plate is rotatably connected to the second plate and the rotation axis of the second plate is d1, and the distance between the position where the transmission plate is rotatably connected to the second plate and the position where the transmission plate is rotatably connected to the cylinder piston rod is d2, where d1=d2;

[0010] During the flipping process, the transmission plate of the flipping platform rotates from horizontal to vertical.

[0011] Preferably, the limiting component includes a sliding seat and a slide rail. The slide rail is fixedly installed on the top surface of the auxiliary frame. A limiting groove is formed on the top surface of the slide rail. The bottom of the sliding seat slides within the limiting groove. The bottom of the sliding seat and the cross-section of the limiting groove are both dovetail-shaped. The end of the transmission plate away from the flipping platform is rotatably connected to the sliding seat.

[0012] Preferably, when the second plate of the flipping platform is vertical, the side of the sliding seat away from the cylinder abuts against the inner wall of the end of the limiting groove away from the cylinder.

[0013] Preferably, the flipping platform is provided with a support base and a fixing block. The support base includes an arc-shaped receiving groove. The workpiece is located in the receiving groove of the support base. The inner peripheral wall of the receiving groove is in contact with the outer peripheral wall of the workpiece. The fixing block is located on the side of the support base near the second plate. The fixing block is fixedly connected to the second plate. The support base is fixedly connected to the fixing block.

[0014] Before the flipping platform is flipped, the first plate is horizontal and the central axis of the support base is vertical. After the flipping platform is flipped, the first plate is vertical and the central axis of the support base is horizontal.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] When flipping the workpiece, the piston rod of the cylinder extends, causing the end of the transmission plate that is rotatably connected to the cylinder to slide away from the cylinder. Since the end of the second plate of the flipping platform is rotatably connected to the support frame, the end of the transmission plate away from the cylinder slowly pushes the flipping platform upward to flip 90°, so that the second plate flips from vertical to horizontal. At this time, the transmission plate is perpendicular to the second plate, so that the flipping platform flips stably. The side of the sliding seat away from the cylinder abuts against the inner wall of the end of the limiting groove away from the cylinder, thereby limiting the two sides of the transmission plate in the vertical state, improving the stability of the flipping platform, and making it very stable even when flipping heavy workpieces.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a workpiece flipping mechanism for a sleeve-making machine.

[0024] Reference Figure 1-4 The workpiece flipping mechanism for the sleeve machine includes a flipping platform 1 and a driving assembly 2 for flipping the flipping platform 1. The flipping platform 1 is L-shaped and includes a first plate 11 and a second plate 12 that are fixedly connected. Before flipping, the first plate 11 is horizontal and the second plate 12 is vertical. After flipping, the first plate 11 is vertical and the second plate 12 is horizontal.

[0025] A support frame 3 is provided on the ground. A rotating shaft is provided at the end of the second plate 12 away from the first plate 11. The rotating shaft is rotatably connected to the support frame 3 through a bearing seat 31. The rotating shaft is fixedly connected to the second plate 12. The bearing seat 31 is fixedly connected to the support frame 3. The rotating shaft is rotatably connected to the bearing seat 31.

[0026] The drive assembly 2 includes a cylinder 21 and a transmission plate 22. An auxiliary frame 4 is provided on the ground. The cylinder 21 is mounted on the auxiliary frame 4. The transmission plate 22 is slidably mounted on the auxiliary frame 4. One end of the transmission plate 22 is rotatably connected to the piston rod of the cylinder 21, and the other end of the transmission plate 22 is rotatably connected to the second plate 12. A limiting assembly 5 is provided on the auxiliary frame 4 to limit the end of the transmission plate 22 away from the flipping platform 1. The limiting assembly 5 keeps the end of the transmission plate 22 away from the flipping platform 1 sliding along the length direction of the auxiliary frame 4.

[0027] The limiting component 5 includes a sliding seat 51 and a slide rail 52. The slide rail 52 is fixedly installed on the top surface of the auxiliary frame 4. A limiting groove 521 is opened on the top surface of the slide rail 52. The bottom of the sliding seat 51 slides in the limiting groove 521. The bottom of the sliding seat 51 and the cross section of the limiting groove 521 are both dovetail-shaped to prevent the sliding seat 51 from disengaging from the limiting groove 521. The end of the transmission plate 22 away from the flipping platform 1 is rotatably connected to the sliding seat 51. During the flipping process, the transmission plate 22 rotates from horizontal to vertical.

[0028] When the second plate 12 of the flipping platform 1 is vertical, the side of the sliding seat 51 away from the cylinder 21 abuts against the inner wall of the limiting groove 521 away from the cylinder 21, thereby limiting the two sides of the transmission plate 22 in the vertical state.

[0029] The distance between the position where the transmission plate 22 is rotatably connected to the second plate 12 and the rotation axis of the second plate 12 is d1, and the distance between the position where the transmission plate 22 is rotatably connected to the second plate 12 and the position where the transmission plate 22 is rotatably connected to the piston rod of the cylinder 21 is d2, where d1=d2.

[0030] The flipping platform 1 is equipped with a support base 6 and a fixing block 7. The support base 6 includes an arc-shaped receiving groove 61. The workpiece 8 is located in the receiving groove 61 of the support base 6. The inner peripheral wall of the receiving groove 61 fits against the outer peripheral wall of the workpiece 8 to prevent the workpiece 8 from rolling on the flipping platform 1 and to keep the workpiece 8 stably positioned on the support base 6. The fixing block 7 is located on the side of the support base 6 near the second plate 12. The fixing block 7 is fixedly connected to the second plate 12, and the support base 6 is fixedly connected to the fixing block 7. Before the flipping platform 1 is flipped, the first plate 11 is horizontal and the central axis of the support base 6 is vertical. After the flipping platform 1 is flipped, the first plate 11 is vertical and the central axis of the support base 6 is horizontal.

[0031] The implementation principle of a workpiece flipping mechanism for a sleeve-making machine according to an embodiment of this application is as follows:

[0032] When flipping workpiece 8, the piston rod of cylinder 21 extends, causing the end of transmission plate 22 that is rotatably connected to cylinder 21 to slide away from cylinder 21. Since the end of the second plate 12 of flipping platform 1 is rotatably connected to support frame 3, the end of transmission plate 22 away from cylinder 21 slowly pushes flipping platform 1 upward to flip 90°, so that the second plate 12 flips from vertical to horizontal. At this time, transmission plate 22 is perpendicular to the second plate 12, so that flipping platform 1 flips stably.

[0033] After the piston rod of cylinder 21 retracts, the end of transmission plate 22 that is rotatably connected to cylinder 21 slides toward the direction closer to cylinder 21, and the end of transmission plate 22 away from cylinder 21 slowly pulls the flipping platform 1 downward and flips it 90° to reset the flipping platform 1.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
