Description

Technical Field

[0001] The utility model relates to the field of forging manipulators, and particularly relates to a moving drive mechanism of a forging manipulator. Background Technique

[0002] A forging manipulator is an important auxiliary mechanical equipment in forging production, mainly used for clamping, flipping, feeding and moving up and down ingots or blanks to replace heavy manual operations and improve the productivity of forging machines. The moving drive mechanism of the forging manipulator is a key part to realize the flexible movement, positioning of the forging manipulator in the forging workshop and cooperate with the forging press to complete the forging process, which is of great significance for improving forging production efficiency and forging quality.

[0003] During the use of the existing moving drive mechanism of the forging manipulator, since the moving drive mechanism is a device installed at the bottom of the forging manipulator to drive the forging manipulator to move flexibly in the forging workshop, and the frame of the moving drive mechanism itself has a large structure, it often abuts against the outside of the forging table and cannot continue to extend in. In this way, the distance between the forging manipulator and the workpiece is not enough, and the operator needs to use external machinery to shorten the distance between the moving drive mechanism of the forging manipulator and the workpiece. This not only takes time and effort and delays the forging time of the workpiece, but also reduces the overall use range of the moving drive mechanism.

[0004] Therefore, it is very necessary to invent a moving drive mechanism of a forging manipulator to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a moving drive mechanism of a forging manipulator. Through the side push plate, hydraulic cylinder, hydraulic rod, sliding groove, moving drive secondary frame, outer wheels and upper mounting frame, it not only shortens the distance for clamping and fixing the forging workpiece for the forging manipulator, but also when clamping the workpiece and moving back and forth, the cooperation between the hydraulic cylinder and the outer wheels also makes the forging manipulator on the upper mounting frame drive more stably back and forth. In this way, under such combined use, it avoids the cumbersome operation that the distance between the forging manipulator and the workpiece is not enough and the operator needs to use external machinery to shorten the distance. It not only saves time and effort and speeds up the forging time of the workpiece, but also expands the overall use range of the moving drive mechanism, so as to solve the problem that during the use of the existing moving drive mechanism of the forging manipulator, since the moving drive mechanism is a device installed at the bottom of the forging manipulator to drive the forging manipulator to move flexibly in the forging workshop, and the frame of the moving drive mechanism itself has a large structure, it often abuts against the outside of the forging table and cannot continue to extend in. In this way, the distance between the forging manipulator and the workpiece is not enough, and the operator needs to use external machinery to shorten the distance between the moving drive mechanism of the forging manipulator and the workpiece. This not only takes time and effort and delays the forging time of the workpiece, but also reduces the overall use range of the moving drive mechanism.

[0006] To achieve the above object, the present utility model provides the following technical solution: A moving drive mechanism of a forging manipulator, including a first-stage moving drive frame for carrying the main body of the moving drive of the forging manipulator;

[0007] An outer load-bearing wheel is arranged outside the first-stage moving drive frame for driving the first-stage moving drive frame to move. A suspension is fixedly installed in front of the first-stage moving drive frame. A steel plate is fixedly installed above the first-stage moving drive frame. A side push plate is arranged above the steel plate. A hydraulic cylinder is fixedly installed on one side of the side push plate. A hydraulic rod is movably connected inside the hydraulic cylinder;

A first torsion turntable is fixedly installed at the output end of the servo motor. A transmission chain belt is movably connected to the outside of the first torsion turntable. A second torsion turntable is movably connected to one side inside the transmission chain belt. A transmission shaft is fixedly installed on the outside of the second torsion turntable.

[0011] Preferably, an outer fixing disc is fixedly installed on the outside of the telescopic rod. A torsion spring is fixedly installed on one side of the outer fixing disc. A fixing block is fixedly installed at one end of the torsion spring. A fixing bolt penetrates above the fixing block.

[0012] Preferably, the second-stage moving drive frame is movably connected to the first-stage moving drive frame. The hydraulic cylinders are symmetrically arranged with respect to the central axis of the side push plate.

[0013] Preferably, the outer running wheel is movably connected to the second-stage moving drive frame. The first torsion turntable and the second torsion turntable are used in cooperation.

[0014] In the above technical solution, the technical effects and advantages provided by the present utility model:

[0015] The utility model is provided with a side push plate, a hydraulic cylinder, a hydraulic rod, a sliding groove, a moving drive secondary frame, an outer wheel and an upper mounting frame. When the moving drive mechanism and the forging manipulator are installed and used, the moving drive primary frame abuts against the outside of the forging table. The moving drive secondary frame can be pushed by the telescopic movement of the hydraulic cylinder and the hydraulic rod. In this way, the servo motor inside the moving drive secondary frame can also drive the outer wheel steadily forward for a certain distance in the sliding groove through the linkage operation of the first torsion turntable and the second torsion turntable. This not only shortens the distance for the forging manipulator to clamp and fix the forging workpiece, but also when clamping the workpiece and moving it back and forth, the cooperation of the hydraulic cylinder and the outer wheel makes the reciprocating drive of the forging manipulator on the upper mounting frame more stable. With such a combined use, it avoids the cumbersome operation that the distance between the forging manipulator and the workpiece is not enough and the operator needs to use external machinery to pull the distance closer. It not only saves time and effort, but also speeds up the forging efficiency of the workpiece, and also expands the overall use range of the moving drive mechanism;

[0016] The utility model is provided with a side positioning frame, a positioning sleeve, a positioning screw, a buffer push plate, a movable frame, a telescopic rod, an outer fixing plate and a torsion spring. When the moving drive mechanism and the forging manipulator are installed and used, the moving drive primary frame with a determined position can be positioned on both sides of the moving drive primary frame through the positioning screws, so that the forging manipulator is more stable during the moving process, reducing the deviation caused by uneven ground or walking error, thereby improving the positioning accuracy. Then, the telescopic rod is extended and the position of the telescopic rod is determined through the fixing block and the fixing bolt. In this way, when the moving drive primary frame is vibrated, the telescopic rod will drive the external torsion spring to expand and contract for buffering and shock absorption, reducing the deviation amplitude of the moving drive primary frame during positioning and ensuring the accurate positioning of the forging manipulator.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] The present utility model provides a moving drive mechanism of a forging manipulator as shown in Figures 1-5 which includes a first-stage moving drive frame 1 for carrying the main body of the moving drive of the forging manipulator;

[0027] An external load-bearing wheel 2 is arranged outside the first-stage moving drive frame 1 and is used to drive the first-stage moving drive frame 1 to move. A suspension 3 is fixedly installed in front of the first-stage moving drive frame 1, a steel plate 14 is fixedly installed above the first-stage moving drive frame 1, a side pushing plate 15 is arranged above the steel plate 14, a hydraulic cylinder 16 is fixedly installed on one side of the side pushing plate 15, and a hydraulic rod 17 is movably connected inside the hydraulic cylinder 16;

[0028] The sliding groove 18 is arranged above the steel plate 14 and is used to assist in pushing and moving the secondary moving drive frame 19. A servo motor 20 is fixedly installed inside the secondary moving drive frame 19. A first torsion turntable 21 is fixedly installed at the output end of the servo motor 20. A drive chain belt 22 is movably connected to the outside of the first torsion turntable 21. A second torsion turntable 23 is movably connected to one side inside the drive chain belt 22. A transmission shaft 24 is fixedly installed on the outside of the second torsion turntable 23. The other end of the transmission shaft 24 is fixedly installed with an outer traveling wheel 25. An upper mounting frame 26 is fixedly installed above the secondary moving drive frame 19. The secondary moving drive frame 19 can be pushed by the telescopic movement of the hydraulic cylinder 16 and the hydraulic rod 17. In this way, the servo motor 20 inside the secondary moving drive frame 19 can also drive the outer traveling wheel 25 through the linkage operation of the first torsion turntable 21 and the second torsion turntable 23, so that the secondary moving drive frame 19 can move forward steadily for a certain distance in the sliding groove 18.

[0029] As Figure 1 , Figure 2 and Figure 3 shown, a side positioning frame 4 is fixedly installed on the outside of the primary moving drive frame 1. A positioning screw sleeve 5 is arranged inside the side positioning frame 4. A positioning screw 6 penetrates through the upper part of the positioning screw sleeve 5. The primary moving drive frame 1 with its position already determined can be positioned on both sides of the primary moving drive frame 1 through the positioning screw 6. A buffer pushing plate 7 is fixedly installed on the back of the primary moving drive frame 1. A movable frame 8 is fixedly installed on the outside of the buffer pushing plate 7. A telescopic rod 9 is movably connected inside the movable frame 8. The movable frame 8 is convenient for retracting the telescopic rod 9 when not in use and for quickly deploying the telescopic rod 9 after the primary moving drive frame 1 is positioned. An outer fixing disk 10 is fixedly installed on the outside of the telescopic rod 9. A torsion spring 11 is fixedly installed on one side of the outer fixing disk 10. One end of the torsion spring 11 is fixedly installed with a fixing block 12. A fixing bolt 13 penetrates through the upper part of the fixing block 12. The position of the telescopic rod 9 is determined by the fixing block 12 and the fixing bolt 13 when the telescopic rod 9 is deployed. In this way, when the primary moving drive frame 1 is vibrated, the telescopic rod 9 will drive the external torsion spring 11 to expand and contract for buffering and shock absorption, reducing the offset amplitude of the primary moving drive frame 1 during positioning.

[0030] As Figure 1 , Figure 4 and Figure 5As shown, the mobile drive secondary frame 19 is movably connected to the mobile drive primary frame 1, the hydraulic cylinder 16 is symmetrically arranged with the central axis of the side push plate 15, and the mobile drive secondary frame 19 is pushed by the extension and contraction of the hydraulic cylinder 16 and the hydraulic rod 17, so that the mobile drive secondary frame 19 can be given enough thrust to carry the forging manipulator to move forward and backward, the outer wheel 25 is movably connected to the mobile drive secondary frame 19, and the first torque turntable 21 is used in conjunction with the second torque turntable 23. The first torque turntable 21 and the second torque turntable 23 have a simple structure and are easy to operate. If a fault occurs, it is also convenient for maintenance personnel to carry out maintenance and replacement in time without delaying the normal use of the device.

[0031] The working principle of the utility model is as follows: first, the external power supply is turned on, and the forging operation machine is installed with the mobile drive mechanism through the upper mounting frame 26. Then, the external vehicle can be connected to the mobile drive mechanism through the suspension 3, and the mobile drive first-level frame 1 is dragged and moved to the vicinity of the forging table. In this way, the mobile drive first-level frame 1 is in contact with the outside of the forging table, and then positioned on both sides of the mobile drive first-level frame 1 through the positioning screws 6. In this way, the forging operation machine is more stable during the movement process, and the deviation caused by uneven ground or walking error is reduced, thereby improving the positioning accuracy. Then, the telescopic rod 9 is unfolded through the movable frame 8, and the position of the telescopic rod 9 is determined through the fixing block 12 and the fixing bolt 13. In this way, when the mobile drive first-level frame 1 is vibrated, the telescopic rod 9 will drive the external torsion spring 11 to retract and buffer the shock, thereby reducing the deviation amplitude of the mobile drive first-level frame 1 during positioning, and ensuring the accurate positioning of the forging operation machine. After the preparation work is completed, the switch of the hydraulic cylinder 16 can be turned on to allow the hydraulic cylinder 16 and the hydraulic rod 17 to retract to drive the mobile drive. The second-stage frame 19 is moved, and then the servo motor 20 is started, so that the servo motor 20 drives the first torque turntable 21 and the second torque turntable 23 in the mobile drive second-stage frame 19 to operate in linkage, so that the outer wheel 25 drives the mobile drive second-stage frame 19 to move steadily forward in the sliding groove 18. This not only shortens the distance for the forging manipulator to clamp the fixed forging workpiece, but also when the forging manipulator clamps the workpiece for reciprocating movement, the cooperation of the hydraulic cylinder 16 and the outer wheel 25 also makes the reciprocating drive of the forging manipulator on the upper mounting frame 26 more stable. Then the forging manipulator can be started to clamp the workpiece being forged, and the forging machine is assisted by the cooperation of the forging manipulator and the mobile drive mechanism to complete the forging work of the workpiece. Finally, after completing the installation and use of the mobile drive mechanism of all forging manipulators according to the above operations, turn off the switch of the hydraulic cylinder 16, turn off the switch of the servo motor 20, and cut off the external power supply if it is not used for a long time. In this way, the use process of the mobile drive mechanism of the forging manipulator is completed.

[0032] Only some exemplary embodiments of the present utility model are described by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
