Description

Technical Field

[0001] This invention relates to the field of shell-making robotic arms, and in particular to a fully automated intelligent shell-making robotic arm. Background Technology

[0002] In the foundry industry, shell-making is one of the key processes to ensure the quality of castings. Traditional shell-making methods rely heavily on manual operation, where workers need to immerse the mold into paint buckets and sand-spreading devices in sequence to complete processes such as coating and sand-spreading. This manual operation method has many drawbacks: First, manual operation is inefficient and cannot meet the needs of large-scale production; second, the shell-making quality is greatly affected by human factors such as worker skill level and working conditions, resulting in unstable product quality, significant differences in parameters such as thickness and uniformity within the same batch, and a high scrap rate; in addition, the shell-making process generates a large amount of dust and harmful gases, and long-term exposure to this working environment poses a serious threat to the health of workers. However, to solve the problems of manual shell-making, existing technologies use robotic arms for shell-making operations, which are pre-programmed to complete the shell-making process according to fixed paths and movements. However, when the shell-making robotic arm is working, the large amount of mechanical movement causes vibration in the base supporting the robotic arm. Over time, the fastening nuts at the bottom are prone to loosening, which affects the stability of the robotic arm connection, and can easily lead to base displacement and a decrease in the positioning accuracy of the robotic arm. More seriously, vibration and loosening can cause abnormal stress on structural components, resulting in fatigue cracks, which may eventually lead to component breakage, damaging the equipment and potentially causing safety accidents, seriously affecting the stability of the shell-making process and production safety. Summary of the Invention

[0003] In view of this, the present invention provides a fully automatic intelligent shell-making robotic arm. Through the reinforcement structure at the connection point of the robotic arm base, a limiting component further strengthens the restraint on the nut, preventing loosening of the nut due to vibration transmission and ensuring the stability of the robotic arm connection. This effectively avoids problems such as base displacement and decreased positioning accuracy of the robotic arm caused by nut loosening, ensuring the stable operation of the shell-making process. Furthermore, through the adjustment components, the robotic arm can flexibly adjust its position according to the actual height of the workpiece, greatly expanding its applicability. This allows the same robotic arm to adapt to shell-making tasks for various workpiece specifications, avoiding the hassle of changing different equipment due to workpiece height differences and reducing equipment procurement costs. On the other hand, during maintenance, the adjustable robotic arm can be lowered to a lower height, allowing maintenance personnel to more easily access various components for inspection, repair, and replacement of parts, reducing the difficulty and safety hazards of maintenance work, shortening maintenance time, and improving the maintainability of the equipment.

[0061] This example: Please refer to Figures 1 to 10 :

[0062] This invention proposes a fully automated intelligent shell-making robotic arm, comprising: a ground 1, an assembly support 2044, and a reinforcing structure 3;

[0063] A fixed base plate 101 is provided on the top of the ground 1. Anchor bolt holes 1011 are provided on the fixed base plate 101, and anchor bolts 102 are installed in the anchor bolt holes 1011. Four sets of support corner blocks 103 are fixedly connected to the top of the fixed base plate 101. An assembly support 2044 is provided on the top of the fixed base plate 101. Reinforcing structures 3 are provided on the four sides of the assembly support 2044. The reinforcing structures 3 include:

[0064] The positioning support plate 301 is fixedly connected to the top of the assembly support 2044. A pre-welded stud 3011 is fixedly connected to the top of the assembly support 2044, and a nut 3012 is engaged on the outside of the pre-welded stud 3011.

[0065] The assembly carrier 302 is located on the top of the assembly support 2044. The bottom of the assembly carrier 302 is provided with a positioning groove 3021 and a through hole 3022 is provided on the assembly carrier 302. The assembly carrier 302 is installed on the pre-welded stud 3011 through the through hole 3022.

[0066] An extension plate 303 is fixedly connected to the four sides of the mounting support 2044. A rotating bracket 3031 is fixedly connected to the top of the extension plate 303. A second screw hole 3032 is provided on the rotating bracket 3031. A guide groove 3033 is provided on the top of the rotating bracket 3031.

[0067] The screw 304 is meshed in the second screw hole 3032, and one end of the screw 304 is fixedly connected to the handle 3041;

[0068] An anti-rotation block 305 is located at the other end of the screw 304. A fixed support ring 3051 is fixedly connected to one end of the anti-rotation block 305 near the screw 304. The screw 304 is rotatably installed in the fixed support ring 3051. A guide support bar 3052 is fixedly connected to the top of the anti-rotation block 305.

[0069] By aligning the through hole 3022 on the assembly carrier 302 with the pre-welded stud 3011 and then tightening it with the nut 3012, the pre-installation is completed. At this time, the screw 304 is rotated by turning the handle 3041. The screw 304 engages and moves in the second screw hole 3032. At the same time, the second screw hole 3032 pushes the anti-rotation block 305 to move. Under the guidance of the guide support 3052 and the guide groove 3033, the anti-rotation block 305 moves smoothly, thereby locking the anti-rotation block 305 on the outside of the nut 3012 and limiting it.

[0070] Example 2: Based on Example 1, wherein, as Figures 2 to 4 As shown, the top of the fixed base plate 101 is provided with an adjustment component 2. The adjustment component 2 includes a fixed support frame 201 and a connecting carrier plate 202. The fixed support frame 201 is fixedly connected to the top of the fixed base plate 101. The connecting carrier plate 202 is fixedly connected to the top of the fixed support frame 201. The top of the connecting carrier plate 202 is fixedly connected to a fixed vertical frame 2021. A through groove 2022 is opened on the side of the fixed vertical frame 2021. A limiting top plate 2023 is fixedly connected to the top of the fixed vertical frame 2021.

[0071] A first motor 203 is fixedly installed inside the fixed support frame 201. The drive end of the first motor 203 is fixedly connected to one end of the first lead screw 2031, and the other end of the first lead screw 2031 is rotatably installed on the bottom of the limiting top plate 2023.

[0072] The fixed vertical frame 2021 has a movable belt plate 204 inside. The movable belt plate 204 has a first screw hole 2041 in the middle. Fixed protrusions 2042 are fixedly connected to the four sides of the movable belt plate 204. The top of the fixed protrusions 2042 is fixedly connected to the assembly support 2044 through the extension carrier plate 2043.

[0073] By starting the first motor 203, the first lead screw 2031 is driven to rotate. The first lead screw 2031 rotates and engages with the first screw hole 2041 on the moving belt plate 204. However, the moving belt plate 204 is limited in the through groove 2022 by the fixed protrusion 2042, so that the first lead screw 2031 drives the moving belt plate 204 to move up and down. The moving belt plate 204 then drives the assembly support 2044 to adjust up and down through the extension carrier plate 2043. Thus, the assembly support 2044 drives the robotic arm structure 4 to adjust up and down.

[0074] Example 3: Based on Examples 1 and 2, wherein, as shown in Example 3... Figures 8 to 10As shown, the top of the assembly carrier 302 is provided with a robotic arm structure 4, which includes a robotic arm 401 and a second motor 402. The robotic arm 401 is fixedly installed on the top of the assembly carrier 302, and the second motor 402 is fixedly installed at the end of the robotic arm 401. A fixed carrier plate 403 is fixedly connected to the bottom of the second motor 402. Fixed vertical plates 4031 are fixedly connected to the middle of the two sides of the fixed carrier plate 403. A connecting base plate 4034 is fixedly connected between the bottom ends of the fixed vertical plates 4031. A second lead screw 4021 is fixedly connected to the drive end of the second motor 402, and the bottom end of the second lead screw 4021 is rotatably mounted on the connecting base plate 4034.

[0075] The two sides of the fixed vertical plate 4031 are fixedly connected to a first hinge 4032 and a second hinge 4033, and a first axle pin 4035 and a second axle pin 4036 are installed on the first hinge 4032 and the second hinge 4033.

[0076] A movable carrier block 404 is provided between the fixed carrier plate 403 and the connecting base plate 4034. A third screw hole 4041 is provided in the middle of the movable carrier block 404. Connecting side frames 4042 are fixedly connected to both sides of the movable carrier block 404. A third shaft pin 4043 is installed on the connecting side frame 4042.

[0077] A hinged arm 405 is provided between the first hinge frames 4032. The corner of the hinged arm 405 is hinged to the first hinge frame 4032 through the first axle pin 4035. One end of the hinged arm 405 is provided with a fourth axle pin 4051. At the same time, the connecting side frame 4042 is hinged to both ends of the first connecting rod 406 through the third axle pin 4043 and the fourth axle pin 4051 respectively. The other end of the hinged arm 405 is fixedly connected to a fixing recess 4052. A fifth axle pin 4053 is provided on the fixing recess 4052.

[0078] The bottom of the fixed recess 4052 is provided with a gripper 407, and the top of the gripper 407 is fixedly connected with a fixed hinge ear 4071. The fixed hinge ear 4071 is hinged to the fixed recess 4052 through a fifth shaft pin 4053. A third hinge 4072 is provided on one side of the fixed hinge ear 4071. A sixth shaft pin 4073 is installed on the third hinge 4072. At the same time, the third hinge 4072 is hinged to the bottom end and the top end of the second connecting rod 408 through the sixth shaft pin 4073 and the second hinge 4033 through the second shaft pin 4036, respectively.

[0079] The sidewall of the gripper 407 is provided with serrated teeth 4074.

[0080] By starting the second motor 402, the second lead screw 4021 is driven to rotate. The second lead screw 4021 rotates and engages with the third screw hole 4041 on the moving block 404. The moving block 404 then pulls the first connecting rod 406 through the connecting side frame 4042. The first connecting rod 406 then drives the hinged arm 405 to move, which in turn drives the gripper 407 to move. By controlling the forward and reverse rotation of the second lead screw 4021, the moving block 404 can be raised and lowered. When the moving block 404 rises, the gripper 407 clamps the object. Conversely, when the moving block 404 falls, the gripper 407 releases the object.

[0081] The specific usage and function of this embodiment: In this invention, the first motor 203 is started to drive the first lead screw 2031 to rotate. The first lead screw 2031 rotates and engages with the first screw hole 2041 on the moving belt plate 204. The moving belt plate 204 is limited in the through groove 2022 by the fixed protrusion 2042, so that the first lead screw 2031 drives the moving belt plate 204 to move up and down. The moving belt plate 204 then drives the assembly support 2044 to adjust its height through the extension carrier plate 2043. Thus, the assembly support 2044 drives the robotic arm structure 4 to adjust its height. It can flexibly adjust its position according to the actual height of the workpiece, which greatly expands the application range of the robotic arm structure 4. It enables the same robotic arm structure 4 to adapt to the shell making task of various specifications of workpieces, avoiding the need to change different equipment due to the difference in workpiece height. The equipment procurement cost is reduced by simplifying the preparation process. Then, by controlling the robotic arm 401 to approach the module, the second motor 402 is started to drive the second lead screw 4021 to rotate. The second lead screw 4021 rotates and engages with the third screw hole 4041 on the moving block 404, causing the moving block 404 to rise. Then, the linkage gripper 407 clamps the module, and the shell-making process can be completed through the preset fixed path and actions. At the same time, by setting a reinforcement structure 3 at the connection of the base of the robotic arm 401, the anti-rotation block 305 further strengthens the limit of the nut 3012, preventing the nut 3012 from loosening due to vibration transmission, ensuring the stability of the connection of the robotic arm 401, and effectively avoiding problems such as base displacement and decreased positioning accuracy of the robotic arm 401 due to loosening of the nut 3012, ensuring that the shell-making process can be carried out stably.
