Description

Technical Field

[0001] The utility model relates to the technical field of forging manipulators, and more particularly to a traction walking mechanism of a full-hydraulic forging manipulator. Background Art

[0002] Forging manipulators are used to clamp and transport red-hot metal products in the workshop. Forging manipulators are divided into tracked and trackless types, and there are also great differences in their use. Tracked manipulators are more commonly used for large metal products and are more stable. When traditional tracked manipulators are processing large metal products, the metal products are supported and located at the front end of the manipulator, which will cause the manipulator to tilt forward. Therefore, as a manipulator supported by walking wheels and pulling the manipulator to move at the same time, since the front end of the manipulator does not have a shock-absorbing and buffering effect on heavy objects, the walking wheels at the rear end of the manipulator may warp or deflect on the guide rail, causing the manipulator to be unable to move stably.

[0003] Patent authorization number CN216140755U discloses a traction and walking mechanism of a fully hydraulic forging manipulator, including a manipulator and an installation cavity fixedly connected to the front end of the manipulator, the installation cavity is used to install and drive the manipulator for walking; two guide rails, a first walking wheel and a second walking wheel are provided on the lower side of the manipulator, the first walking wheel and the second walking wheel are symmetrically arranged and rotatably connected to the guide rails, and the liquid passing through the lower side of the piston will flow to the upper side through the through hole on the piston. Since the through hole is small, the liquid flow rate is slow, which plays a buffering role when the installation cavity moves downward. Since a spring is fixedly connected between the sealing cavity and the installation cavity, the spring can play a shock-absorbing and buffering role when the installation cavity moves downward, thereby effectively achieving a shock-absorbing effect on the manipulator body while the manipulator is towed and walking.

[0004] However, when the walking mechanism in patent authorization number CN216140755U supports and pulls the workpiece and reaches the designated workstation, the walking mechanism cannot brake quickly, causing the pulled workpiece to easily deviate from the processing station, thereby affecting the processing of the workpiece. Therefore, we proposed a traction walking mechanism of a fully hydraulic forging manipulator to solve the above problems. Utility Model Content

[0032] The outer wall portion of the wheel axle 7 located between the connecting frames 6 is rotatably connected to a driven gear 9. A strip hole 10 is transversely opened at the portion of the base 2 corresponding to the driven gear 9. A sleeve 11 corresponding to the driven gear 9 is welded to the inner wall of the strip hole 10. A movable rod 12 is inserted into the side wall of the sleeve 11, and multiple movable rods 12 are provided. A brake pad 13 is installed at one end of the movable rod 12 close to the wheel axle 7.

[0033] A driving motor 16 is installed on one side of the top opening of the strip-shaped hole 10, and a driving gear 17 meshing with the driven gear 9 is installed at the power output end of the driving motor 16;

[0034] It should be noted that when the traction walking mechanism of the fully hydraulic forging manipulator is working, the workpiece is clamped by the manipulator body 5, and then the driving mechanism located inside the mounting cavity 4 drives the active walking wheel 3 to cooperate with the guide rail 1 to roll, and the driven walking wheel 8 cooperates with the guide rail 1 to roll and carry the workpiece to the designated workstation. The drive motor 16 is connected to an external control device, and the control device is used to set the forward and reverse rotation program for the drive motor 16, and the power output end of the drive motor 16 is equipped with a locking assembly. When the output shaft of the drive motor 16 stops rotating, the locking assembly is used to lock the output shaft of the drive motor 16;

[0035] The driving gear 17 is driven to rotate by the power output end of the driving motor 16, so that the driven gear 9 rotates in conjunction with the wheel shaft 7, and then the guide rod 14 slides inside the arc-shaped guide hole 15, so that the guide rod 14 moves toward the axial center of the driven gear 9, and the movable rod 12 slides in conjunction with the sleeve 11 until the brake pad 13 abuts against the wheel shaft 7, thereby quickly achieving rapid braking of the traction walking mechanism, avoiding the workpiece from deflecting when it reaches the work station, which is beneficial to the forging processing of the workpiece.

[0036] like Figure 1 As shown, the edge of the base 2 away from the mounting cavity 4 is installed with an audible and visual alarm lamp 18, and two audible and visual alarm lamps 18 are symmetrically arranged;

[0037] It should be noted that, during the operation of the traction traveling mechanism, the sound and light alarm light 18 works to remind nearby workers to stay away from the traction traveling mechanism, thereby ensuring the safety of the workers during the forging process of the workpiece.

[0038] like Figure 2 As shown, a bearing is installed at the portion where the connecting frame 6 and the wheel axle 7 are combined;

[0039] It should be noted that the friction between the wheel axle 7 and the connecting frame 6 is reduced, and the rotation accuracy of the wheel axle 7 is guaranteed.

[0040] like Figure 2 、 Figure 4 As shown, a bearing is installed in the middle of the driven gear 9, and the bearing is interference-connected with the axle 7;

[0041] It should be noted that the driving gear 17 is locked by the power output end of the driving motor 16 , so that the driving gear 17 is used to position the driven gear 9 , and the bearing is used to make the wheel shaft 7 rotate relative to the driven gear 9 .

[0042] like Figure 2 、 Figure 3 、 Figure 4 As shown, there are three movable rods 12, and the angle between the axis of the corresponding housing 11 of two adjacent movable rods 12 is 120°. The brake pad 13 is arranged in an arc-shaped structure, and the curvature of the brake pad 13 is adapted to the outer diameter of the wheel axle 7. The axis of the driven gear 9, the housing 11 and the wheel axle 7 are all located on the same straight line;

[0043] It should be noted that the wheel axle 7 can be braked quickly.

[0044] like Figure 2 、 Figure 3 As shown, a through hole is opened in the middle of the housing 11, and the inner diameter of the through hole is larger than the outer diameter of the axle 7;

[0045] It should be noted that friction between the axle 7 and the housing 11 is avoided.

[0046] During use: the workpiece is clamped by the operating machine body 5, and then the driving mechanism located inside the installation cavity 4 drives the active walking wheel 3 to roll with the guide rail 1, while the driven walking wheel 8 rolls with the guide rail 1 to carry the workpiece to the designated workstation. The drive motor 16 is connected to an external control device, and the control device is used to set the forward and reverse rotation program for the drive motor 16. The power output end of the drive motor 16 is equipped with a locking assembly. When the output shaft of the drive motor 16 stops rotating, the locking assembly is used to lock the output shaft of the drive motor 16.

[0047] The driving gear 17 is driven to rotate by the power output end of the driving motor 16, so that the driven gear 9 rotates in conjunction with the wheel axle 7, and then the guide rod 14 slides inside the arc-shaped guide hole 15, so that the guide rod 14 moves toward the axial center of the driven gear 9, and the movable rod 12 slides in conjunction with the sleeve 11 until the brake pad 13 abuts against the wheel axle 7, thereby quickly achieving rapid braking of the traction walking mechanism.
