[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0025] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the steel sleeve feeding and casting unloading robot for die casting of lower cylinder housing includes a fixed base 1 for fixing and connecting the robot arm. One side of the fixed base 1 is provided with a feeding mechanism 2 for feeding the steel sleeve 9 for die casting of the casting 8, and the other side of the fixed base 1 is provided with a unloading mechanism 3 for removing the die-cast casting 8 from the mold.

[0026] This utility model proposes a robotic arm for feeding and unloading steel sleeves for die casting of lower cylinder housing castings. A fixed base 1 is used to fix and connect the robotic arm. As the supporting structure for the entire robotic arm, it ensures the stability and accuracy of the robotic arm during operation. A feeding mechanism 2 is located on one side of the fixed base 1 and can feed the steel sleeve 9 used for die casting of the casting 8. The feeding mechanism 2 can grasp, position, and place the steel sleeve 9 to the designated position on the die casting machine, preparing it for the subsequent die casting process.

[0027] The material handling mechanism 3 is located on the other side of the fixed base 1 and is capable of removing the die-cast part 8 from the mold. The material handling mechanism 3 can accurately identify and grasp the die-cast part 8 and then remove it from the mold for subsequent processing or transportation.

[0028] The robotic arm is connected to the fixed base 1 and adjusted to the appropriate working position. The loading mechanism 2 and the unloading mechanism 3 are in standby mode, ready to perform loading and unloading operations.

[0029] When material needs to be loaded, the loading mechanism 2 begins operation. It grips the steel sleeve 9 from its storage location. The loading mechanism 2 accurately places the steel sleeve 9 into the designated position on the die-casting machine, preparing it for the die-casting process. The die-casting machine begins operation, die-casting the part 8 into the desired shape. During this process, both the loading mechanism 2 and the picking mechanism 3 of the robotic arm remain in a waiting state until the die-casting is complete. Once the die-casting is complete, the picking mechanism 3 begins operation. It locates and grips the die-cast part 8. Then, the picking mechanism 3 removes the part 8 from the mold and places it in a designated location or on a transport device for further processing or transportation.

[0030] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the material handling mechanism 3 includes a double-rail slide finger motor 4 disposed on the side of the fixed base 1. The double-rail slide finger motor 4 has two movable chucks 5 that move in opposite directions mounted on the two slides of the double-rail slide finger motor 4. A positioning mechanism 6 is fixedly disposed on the outside of the movable chucks 5.

[0031] Specifically, the dual-rail slide finger motor 4 is mounted on the side of the fixed base 1. It provides stable and precise linear motion, ensuring that the moving parts can move accurately along a predetermined path. The dual-rail slide finger motor 4 is equipped with two slides, which form the mounting base for the movable chucks 5. Guided by the dual rails, the slides can perform smooth and accurate linear motion. The two movable chucks 5 are mounted on the two slides respectively and are designed to move in opposite directions. This allows the movable chucks 5 to open or close as needed to grip or release the casting 8.

[0032] The positioning mechanism 6 is fixedly mounted on the outside of the movable chuck 5 to provide precise positioning when gripping the casting 8. The positioning mechanism 6 ensures that the movable chuck 5 can be accurately aligned with the gripping point of the casting 8.

[0033] Before starting work, the material handling mechanism 3 is in its initial state, with the dual-rail slide finger motor 4, slide, movable chuck 5, and positioning mechanism 6 all in predetermined positions. The system prepares for the gripping operation according to a preset program or external command. Upon receiving a gripping command, the dual-rail slide finger motor 4 starts working, driving the slide to move along the guide rail. The slide moves the movable chuck 5 towards the casting 8, while the positioning mechanism 6 starts working to ensure that the movable chuck 5 accurately aligns with the gripping point of the casting 8. When the movable chuck 5 reaches the predetermined position, the dual-rail slide finger motor 4 controls the slide to move the two movable chucks 5 towards each other, firmly gripping the casting 8. The positioning mechanism 6 ensures the accuracy and stability of the gripping. After gripping the casting 8, the dual-rail slide finger motor 4 works again, driving the slide to move in the opposite direction along the guide rail, removing the casting 8 from the mold. Then, the material handling mechanism 3 can move the casting 8 to a designated location or transport equipment as needed, completing the material handling process. After the material is picked up, the picking mechanism 3 resets to its initial state and waits for the next picking command.

[0034] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the positioning mechanism 6 includes positioning frames 61 set on both sides of the front end of the dual-rail slide finger motor 4, and a semi-circular positioning block 62 matching the outer contour of the clamping part of the casting 8 is set on the top of the positioning frame 61.

[0035] Specifically, the positioning frame 61 is set on both sides of the front end of the dual-rail slide finger motor 4, not only providing installation positions for other components, but also ensuring the stability and rigidity of the entire positioning mechanism 6 during the material handling process. The semi-circular positioning block 62 is installed on the top of the positioning frame 61, and its shape matches the outer contour of the clamping part of the casting 8, so that the positioning block 62 can fit tightly against the casting 8, thereby providing accurate positioning and stable support during the gripping process.

[0036] As the dual-rail slide finger motor 4 drives the slide and movable chuck 5 to move towards the casting 8, the positioning mechanism 6 also approaches the casting 8. During this process, the positioning frame 61 remains stable, providing an accurate movement path for the semi-circular positioning block 62. As the movable chuck 5 approaches, the semi-circular positioning block 62 first contacts the outer contour of the clamping area of ​​the casting 8. Because the shape of the semi-circular positioning block 62 matches the outer contour of the casting 8, they fit together, providing initial positioning for subsequent gripping.

[0037] Based on the initial positioning by the semi-circular positioning block 62, the movable chuck 5 continues to move towards the casting 8, firmly gripping it. At this time, the positioning mechanism 6, through the contact between the semi-circular positioning block 62 and the casting 8, ensures the accuracy and stability of the gripping, preventing the casting 8 from sliding or shifting during the gripping process. After gripping the casting 8, the dual-guide rail slide finger motor 4 drives the slide and the entire material handling mechanism 3 to move, removing the casting 8 from the mold and placing it in the designated position. During this process, the positioning mechanism 6 always maintains contact with the casting 8, ensuring the stability and safety of the casting 8 during movement. After completing the material handling, the positioning mechanism 6, together with the material handling mechanism 3, resets to its initial state, preparing for the next gripping operation.

[0038] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a clamping block 51 for contacting the casting 8 being transported is installed at the front end of the movable chuck 5 facing outwards. Anti-slip texture 52 is provided on the clamping surface of the clamping block 51.

[0039] Specifically, the movable chucks 5 can move towards or away from each other to accommodate the gripping needs of castings of different sizes. A clamping block 51 is mounted on the front end of the movable chuck 5 (i.e., the side facing the casting 8 being handled), serving as the medium for direct contact with the casting 8. The clamping block 51 is fixed to the front end of the movable chuck 5 and faces the other movable chuck 5 (i.e., the two clamping blocks 51 are arranged opposite each other). As the component that directly contacts the casting 8, the clamping block 51 must bear the gripping force and transmit it to the casting 8, while protecting the surface of the casting 8 from damage.

[0040] Anti-slip texture 52 is etched or molded onto the clamping surface of the clamping block 51 (i.e., the surface in contact with the casting 8). This prevents the casting 8 from slipping due to vibration, inertia, or oil contamination during gripping or handling, ensuring gripping stability.

[0041] Combination Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the feeding mechanism 2 includes a motor 21 mounted on a fixed base 1, and the output end of the motor 21 is connected to a fixing head 22 for fixing the steel sleeve 9.

[0042] Specifically, motor 21 is fixed to the mounting base 1, with its output end facing vertically or horizontally toward the processing area (designed according to the fitting direction of the steel sleeve 9). The fixed head 22 is driven to rotate by rotating the output end, thus achieving automatic fitting of the steel sleeve 9. The fixed head 22 and the output end of motor 21 are fixedly connected via a coupling or keyway to ensure synchronous rotation. The fixed head 22 has a shape that matches the inner hole of the steel sleeve 9 (e.g., cylindrical, conical, or stepped), and its surface may be hardened (e.g., quenched) to enhance wear resistance.

[0043] Combination Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the fixed head 22 includes a circular outer shell 221. A movable push rod 222 is provided at the axis of the circular outer shell 221. Multiple holes 223 are equidistantly arranged in a ring on the circular outer shell 221. Each hole 223 is provided with a ball 224 inside. The outer wall of all the balls 224 abuts against the top of the movable push rod 222.

[0044] Specifically, the circular outer shell 221 is made of high-strength metal (such as alloy steel) or wear-resistant engineering plastic to ensure structural rigidity and impact resistance. As the main support structure of the fixed head 22, it provides installation space for internal components and withstands external forces during the installation process. The movable push rod 222 pushes the balls 224 radially to expand or contract through axial movement, achieving clamping and releasing of the steel sleeve 9. The balls 224 are evenly distributed (usually 3-8) along the circumference of the circular outer shell 221, with a diameter slightly larger than the diameter of the balls 224, ensuring that the balls 224 can roll freely but are not easily dislodged. The inner wall of the holes 223 may be machined with guide grooves or chamfers to guide the balls 224 along a predetermined path and prevent deflection. The balls 224, as the medium for transmitting clamping force, convert the axial force of the push rod into radial clamping force through contact with the movable push rod 222 and the inner wall of the steel sleeve 9. The number of balls 224 is consistent with the number of holes 223 to ensure uniform distribution of clamping force.

[0045] When the movable push rod 222 is in its lowest position (away from the steel sleeve 9), the contact force between the top of the push rod and the ball 224 is minimal. Under its own weight or a slight spring force, the ball 224 partially retracts into the hole 223. The diameter of the exposed part of the ball 224 is smaller than the inner diameter of the steel sleeve 9, allowing the steel sleeve 9 to be freely inserted or removed. At this time, the fixed head 22 has no effective clamping force on the steel sleeve 9 and is in a standby state. When the sensor detects that the steel sleeve 9 is inserted into the fixed head 22 or receives a clamping command, the motor 21 pushes the movable push rod 222 (towards the steel sleeve 9) to move. The tapered surface at the top of the movable push rod 222 contacts the ball 224. As the movable push rod 222 moves, the radial component of the force exerted by the tapered surface on the ball 224 gradually increases. Under the action of this component force, the ball 224 rolls outward along the hole 223 until the outer wall of the ball 224 is in close contact with the inner wall of the steel sleeve 9. All the balls 224 expand synchronously, forming a uniform radial clamping force to fix the steel sleeve 9 onto the fixed head 22. The clamping force can be controlled by adjusting the stroke of the movable push rod 222 to accommodate steel sleeves of different specifications. The motor 21 drives the fixed head 22 to rotate, pressing the fixed head 22 (along with the clamped steel sleeve 9) into the target shaft or workpiece. The centrifugal force generated by the rotation keeps the steel sleeve 9 tightly against the balls 224, reducing the risk of slippage; the axial thrust ensures proper placement.

[0046] After the sleeve is installed, the motor 21 pulls the movable push rod 222 to move in the opposite direction, reducing the contact force between the top of the movable push rod 222 and the ball bearing 224. Under the pressure of the inner wall of the steel sleeve 9 or its own weight, the ball bearing 224 retracts into the hole 223, reducing the exposed diameter of the ball bearing 224, and the steel sleeve 9 is released. The fixed head 22 returns to its initial position, waiting for the next feeding cycle.

[0047] Combination Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the movable top rod 222 includes a rod body 2221 connected to the output end of the motor 21. The top end of the rod body 2221 is provided with a conical top joint 2222, and the outer wall of the top joint 2222 abuts against the outer wall of the ball 224.

[0048] Specifically, the rod 2221 is connected to the output end of the motor 21. Through this connection, the power of the motor 21 can be transmitted to the movable push rod 222, causing it to move accordingly. The top joint 2222 is located at the top of the rod 2221 and is conical in shape. The outer wall of the top joint 2222 abuts against the outer wall of the ball bearing 224, and there is an interaction between them, involving the transmission of force or a change in the mode of motion.

[0049] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the fixed base 1 is provided with a connecting rod 7 for connecting with the robotic arm, and the connecting rod 7 has bolt holes.

[0050] Specifically, the connecting rod 7 is mounted on the fixed base 1 and is used to establish a connection with the robotic arm. The connecting rod 7 is generally a slender rod, and its length, diameter, and cross-sectional shape are designed according to the connection method with the robotic arm and the magnitude of the force it will withstand. Bolt holes are formed on the connecting rod 7 and are used to securely connect the connecting rod 7 to the robotic arm using bolts. The bolt holes are evenly distributed at the end of the connecting rod 7 where it connects to the robotic arm or at suitable locations to ensure the stability and reliability of the connection.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
