Description

Technical Field

[0001] This utility model relates to the field of stamping auxiliary equipment technology, and in particular to a rotating mechanism for a stamping manipulator. Background Technology

[0002] A stamping robot is an automated device designed specifically for stamping production scenarios. It uses a programmable control system to drive the mechanical structure and perform operations such as gripping, handling, positioning, and loading / unloading of stamped workpieces. It can precisely coordinate with the working rhythm of the stamping machine and replace manual labor in repetitive, labor-intensive, and safety-risk processes. When the robot handles workpieces, a corresponding rotating mechanism is required to drive the robot to adjust its angle.

[0003] During long-term operation, gears in rotating mechanisms are prone to insufficient lubrication. To perform lubrication replenishment and other maintenance, maintenance personnel need to periodically remove the protective casing of the rotating mechanism, which significantly increases maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that maintenance personnel need to regularly remove the protective shell of the rotating mechanism when performing maintenance operations such as replenishing lubricating oil on gears, which significantly increases the maintenance cost of the rotating mechanism. Therefore, a rotating mechanism for a stamping manipulator is proposed.

[0009] Preferably, the lubrication brush includes a mounting plate, a protrusion, and a brush body. The protrusion and the brush body are respectively fixedly connected to both sides of the mounting plate. Iron sheets are symmetrically fixedly connected to one side of the mounting plate, and the iron sheets are magnetically connected to a magnet.

[0010] Preferably, the rotary drive assembly includes a drive motor, a speed changer, and a drive gear.

[0013] 1.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 - Figure 5As shown, this utility model provides a rotating mechanism for a stamping-type robotic arm, including a mounting platform 1. A transmission gear 11 is rotatably connected to the center of the mounting platform 1. A rotation drive assembly 2 is driven to the outer side of the transmission gear 11. A transmission disk 12 is fixedly connected to the center of the transmission gear 11. A robotic arm is fixedly connected to the top of the transmission disk 12. A protective shell 3 is provided on the outer side of the transmission gear 11. A lubricating oil supply assembly 4 is provided on the outer side of the protective shell 3. The output end of the lubricating oil supply assembly 4 is fixedly connected to a lubricating oil output chamber 5. The lubricating oil output chamber 5 is disposed in the gap between the protective shell 3 and the transmission gear 11. A mounting groove 31 is provided on one side of the protective shell 3. A lubricating brush 6 is movably engaged inside the mounting groove 31. The lubricating oil supply assembly 4 includes a lubricating oil tank 41, an oil delivery chamber 42, an electrically controlled valve 43, and an oil delivery pipe 44. One end of the lubricating oil tank 41 is fixedly connected to the input end of the oil delivery chamber 42. The output end of the oil delivery chamber 42 is fixedly connected to one end of the electrically controlled valve 43. The other end of the electrically controlled valve 43 is fixedly connected to one end of the oil delivery pipe 44. One side of the lubricating oil output chamber 5 is fixedly connected to one end of the oil delivery pipe 44. Several oil outlets 51 are provided on the other side of the lubricating oil output chamber 5 in a linear arrangement.

[0025] The specific settings and functions of this embodiment are described below. When the transmission gear 11 needs to be lubricated, the electrically controlled valve 43 is opened. The lubricating oil in the lubricating oil tank 41 enters the lubricating oil output chamber 5 through the oil delivery chamber 42 and the oil delivery pipe 44 in sequence. Then, it drips evenly onto the outside of the transmission gear 11 through several oil outlets 51, effectively lubricating the transmission gear 11 without disassembling the protective shell 3, thereby reducing maintenance costs.

[0026] Example 2: Figure 1 - Figure 6As shown, the rotating mechanism of the stamping-type robotic arm in this utility model includes a mounting platform 1. A transmission gear 11 is rotatably connected to the center of the mounting platform 1. A rotation drive assembly 2 is driven to the outer side of the transmission gear 11. A transmission disk 12 is fixedly connected to the center of the transmission gear 11. A robotic arm is fixedly connected to the top of the transmission disk 12. A protective shell 3 is provided on the outer side of the transmission gear 11. A lubricating oil supply assembly 4 is provided on the outer side of the protective shell 3. The output end of the lubricating oil supply assembly 4 is fixedly connected to a lubricating oil output chamber 5. The lubricating oil output chamber 5 is located in the gap between the protective shell 3 and the transmission gear 11. A mounting groove 31 is opened on one side of the protective shell 3. A lubricating brush 6 is movably engaged inside the mounting groove 31. A positioning plate 311 is symmetrically fixedly connected to the inner side of the mounting plate 1. A magnet is fixedly connected to one side of the positioning plate 311. The lubrication brush 6 includes a mounting plate 61, a protrusion 62, and a brush body 63. The protrusion 62 and the brush body 63 are respectively fixedly connected to both sides of the mounting plate 61. An iron sheet is symmetrically fixedly connected to one side of the mounting plate 61. The iron sheet and the magnet are magnetically connected to each other. The rotary drive assembly 2 includes a drive motor 21, a speed changer 22, and a drive gear 23. The output end of the drive motor 21 is connected to the input end of the speed changer 22. The output end of the speed changer 22 is fixedly connected to the center of the drive gear 23. The drive gear 23 meshes with the outer side of the transmission gear 11. Support frames 13 are fixedly connected to both ends of one side of the mounting plate 1.

[0027] The overall effect of this embodiment is that when the lubricating oil drips from the lubricating oil output chamber 5 to the outside of the transmission gear 11, some of the lubricating oil will seep into the interior of the brush body 63. During the operation of the drive motor 21 driving the transmission gear 22, the drive gear 23 drives the transmission gear 11 to rotate. At this time, the brush body 63 can evenly apply lubricating oil to the outside of the transmission gear 11. Through the cooperation between the brush body 63 and the transmission gear 11, the lubricating oil is dynamically and evenly applied, avoiding the problem of local accumulation or uneven distribution of lubricating oil in the traditional dripping method. This ensures that all areas of the meshing surface of the transmission gear 11 are fully lubricated, effectively reducing the wear rate of the gears due to poor lubrication, and improving the stability and reliability of the gear transmission. The lubricating oil is absorbed by the brush body 63 and then gradually released, which can reduce the excessive consumption of lubricating oil, reduce the cost of lubricating materials, and avoid environmental pollution and resource waste caused by excess lubricating oil dripping, which meets the requirements of energy-saving and environmentally friendly production. When it is necessary to replace the lubricating brush 6, the maintenance personnel can remove the lubricating brush 6 from the mounting groove 31 by grasping the protrusion 62, and at the same time, the magnetic connection between the iron piece and the magnet can be released to complete the disassembly.

[0028] The device's operation and working principle are as follows: When lubrication of the transmission gear 11 is required, the electrically controlled valve 43 opens, and the lubricating oil in the lubricating oil tank 41 flows sequentially through the oil delivery chamber 42 and the oil pipe 44 into the lubricating oil output chamber 5. Then, it drips evenly onto the outside of the transmission gear 11 through several oil outlets 51, effectively lubricating the transmission gear 11. When the lubricating oil drips from the lubricating oil output chamber 5 onto the outside of the transmission gear 11, some of the lubricating oil will seep into the brush body 63. During the operation of the drive motor 21 driving the transmission gear 22, the drive gear 23 drives the transmission gear 11 to rotate. At this time, the brush body 63 can evenly coat the outside of the transmission gear 11 with lubricating oil.

[0029] When the lubrication brush 6 needs to be replaced, the maintenance personnel can remove the lubrication brush 6 from the mounting groove 31 by grasping the protrusion 62, and at the same time, the magnetic connection between the iron sheet and the magnet can be released to complete the disassembly.

[0030] When the robot arm needs to be driven to rotate, the rotation drive component 2 drives the transmission gear 11 to rotate, and under the transmission of the transmission disk 12, it drives the robot arm to adjust the corresponding rotation angle.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
