Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of parts retrieval equipment, specifically relating to a cold chamber parts retrieval machine. Background Technology
[0002] Die casting machines are used to inject molten metal into a pre-designed mold cavity, where it is cooled and solidified under high pressure and high speed to create metal products of various complex shapes. Die casting machines are generally classified into hot chamber die casting machines and cold chamber die casting machines according to the working state of their pressure chambers. In a hot chamber die casting machine, the pressure chamber is immersed in molten metal in a holding crucible, and the injection mechanism is installed above the holding crucible. In a cold chamber die casting machine, the pressure chamber is separate from the holding furnace; molten metal is taken from the holding furnace and injected into the pressure chamber for die casting.

Furthermore, when a round workpiece is subjected to clamping force, due to its shape, the force may concentrate at certain points, causing excessive pressure on the material at those points, while other points may experience insufficient force. This uneven distribution of clamping force can lead to workpiece deformation, cracking, or damage. Utility Model Content

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:
[0019] This utility model's cold chamber part-retrieving machine utilizes a base, a sliding mechanism, a rotating mechanism, and a part-retrieving mechanism in cooperation. The sliding mechanism is mounted on the base, and the part-retrieving mechanism includes a rotating arm and a clamp connected to the other end of the rotating arm. One end of the rotating arm is connected to the sliding mechanism via the rotating mechanism. The sliding mechanism drives the rotating mechanism and the rotating arm to slide along the z-axis, effectively enabling the rotating mechanism and the rotating arm to move forward or backward along the z-axis, effectively expanding the part-retrieving range of the clamp, improving the flexibility of the part-retrieving machine, and thus improving the part-retrieving efficiency. The clamp has two opposing clamping parts, each with a clamping block. By making the thickness of the middle part of the clamping block less than the thickness of its edge along the x-axis, this structure allows for a more even distribution of clamping force when clamping a workpiece. Because the middle part is thinner, the clamping force is more concentrated upon contact with the workpiece, while the thicker edge provides sufficient support, preventing workpiece deformation or damage caused by excessive concentration of clamping force. In addition, by setting an anti-slip layer on the upper surface of the clamping block, the anti-slip performance of the clamp is further enhanced, effectively increasing the friction between the clamp and the workpiece, preventing the workpiece from sliding or shifting during clamping, thereby enhancing clamping stability.

[0043] The following will be combined with the appendix Figures 1-8 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0044] Please see Figures 1-8 The cold chamber retrieval machine 100 of this utility model includes a base 10, a sliding mechanism 20, a rotating mechanism 30, and a retrieval mechanism 40. The sliding mechanism 20 is disposed on the base 10, and the rotating mechanism 30 is rotatably disposed on the sliding mechanism 20. The retrieval mechanism 40 includes a rotating arm 41 and a clamp 42. One end of the rotating arm 41 is connected to the rotating mechanism 30, and the clamp 42 is connected to the other end of the rotating arm 41. The clamp 42 has two opposing clamping parts 421, and each clamping part 421 has a clamping block 422. Along the x-axis direction, the thickness of the middle part of the clamping block 422 is less than the thickness of the edge of the clamping block 422, and the upper surface of the clamping block 422 is provided with an anti-slip layer 423.
[0045] Compared with the prior art, the cold chamber retrieval machine 100 of this utility model uses a base 10, a sliding mechanism 20, a rotating mechanism 30 and a retrieval mechanism 40 in cooperation. The sliding mechanism 20 is set on the base 10. The retrieval mechanism 40 includes a rotating arm 41 and a clamp 42 connected to the other end of the rotating arm 41. One end of the rotating arm 41 is connected to the sliding mechanism 20 through the rotating mechanism 30. The sliding mechanism 20 is used to drive the rotating mechanism 30 and the rotating arm 41 to slide along the z-axis, effectively enabling the rotating mechanism 30 and the rotating arm 41 to move forward or backward along the z-axis, effectively expanding the retrieval range of the clamp 42, improving the flexibility of the retrieval machine, and thus improving the retrieval efficiency of the retrieval machine. The fixture 42 has two opposing clamping portions 421, each with a clamping block 422. By making the thickness of the middle portion of the clamping block 422 less than the thickness of its edges along the x-axis, this structure allows for a more even distribution of clamping force when clamping the workpiece. The thinner middle portion concentrates the clamping force upon contact with the workpiece, while the thicker edges provide sufficient support, preventing workpiece deformation or damage caused by excessive force concentration. Furthermore, an anti-slip layer 423 on the upper surface of the clamping block 422 further enhances the anti-slip performance of the fixture 42, effectively increasing the friction between the fixture 42 and the workpiece, preventing the workpiece from sliding or shifting during clamping, thereby enhancing clamping stability.
[0046] Please see Figures 1-3 as well as Figures 4-5In some embodiments, the thickness of the clamping block 422 decreases from its edge to its center along the x-axis. By setting the thickness of the clamping block 422 to decrease from its edge to its center along the x-axis, this design allows for a more even distribution of clamping force when holding a circular workpiece. Because the thickness is thinner in the center, the clamping force is more concentrated upon contact with the workpiece, while the thicker edges provide sufficient support, preventing workpiece deformation or damage caused by excessive concentration of clamping force. This design helps protect the workpiece and ensure its integrity. Furthermore, the gradual decrease in thickness from the edge to the center increases the contact area between the clamping block 422 and the workpiece, thereby improving clamping stability. Even with minor unevenness or dirt on the workpiece surface, the clamping block 422 can better adapt to and firmly clamp the workpiece.
[0047] Please see Figures 1-3 as well as Figures 4-5 In some embodiments, the upper surface of the clamping block 422 has a first region and a second region adjacent to the first region. Along the x-axis, the first region is located at the edge of the upper surface of the clamping block 422, and the second region is located in the middle of the upper surface of the clamping block 422. An anti-slip layer 423 is disposed in the first region, and a groove 4221 is provided in the second region of the clamping block 422. By disposing the anti-slip layer 423 in the first region, i.e., the edge of the upper surface of the clamping block 422, this design allows the edge portion of the clamp 42 to provide greater friction when clamping a circular workpiece, effectively preventing the workpiece from slipping during clamping. Especially when the workpiece surface is smooth or wet, the anti-slip layer 423 can significantly enhance the stability of clamping. By placing the second region in the middle of the upper surface of the clamping block 422 and providing the groove 4221, this design helps to disperse the clamping force, avoiding excessive concentration of clamping force in a small area, thereby reducing the risk of deformation or damage to the workpiece due to excessive clamping force. Meanwhile, the design of the groove 4221 also increases the elasticity of the clamping block 422, allowing it to better adapt to workpieces of different shapes. Furthermore, by providing an anti-slip layer 423 in the first area and a groove 4221 in the second area, the fixture 42 can more accurately position the workpiece when clamping it. The anti-slip layer 423 provides a stable clamping point, while the groove 4221 helps adjust the gap between the fixture 42 and the workpiece, ensuring tightness and accuracy of clamping.
[0048] Please see Figure 3 as well as Figure 5In some embodiments, the anti-slip layer 423 is an uneven textured structure formed on the upper surface of the clamping block 422; or, the anti-slip layer 423 is a rubber layer; or, the anti-slip layer 423 is a resin layer. By forming an uneven textured structure on the upper surface of the clamping block 422, the coefficient of friction between the clamp 42 and the workpiece is effectively increased. This change in physical structure makes it more difficult for the workpiece to slip during clamping, thereby improving clamping stability. By making the anti-slip layer 423 a rubber layer or a resin layer, both rubber and resin materials have excellent anti-slip properties, which not only provide stable clamping force but also protect the workpiece surface from scratches or wear to a certain extent. In addition, the versatility of the anti-slip layer 423 allows the clamp 42 to adapt to round workpieces of different materials, shapes, and sizes. Whether it is a smooth metal surface, a rough plastic surface, or other special materials, the clamp 42 can provide a stable clamping effect.
[0049] Please see Figures 1-2 , Figure 4 as well as Figure 6 In some embodiments, the rotating arm 41 includes a support base 411, a rotating shaft 412, a motor 413, and a cylinder 414. The support base 411 is connected to the rotating mechanism 30. The rotating shaft 412 is rotatably mounted on the support base 411. One end of the rotating shaft 412 is provided with a first gear 415, and the other end of the rotating shaft 412 is connected to the clamp 42. The motor 413 is mounted on the support base 411, and a second gear 416 is provided on the output shaft of the motor 413. The first gear 415 and the second gear 416 mesh. The cylinder 414 is mounted on one end of the rotating shaft 412, and the output shaft of the cylinder 414 passes through the rotating shaft 412 and is connected to the clamp 42. Through the coordinated use of the support base 411, the rotating shaft 412, the motor 413, and the cylinder 414, the rotating arm 41 is connected to the rotating mechanism 30 via the support base 411, ensuring the stability and reliability of the overall structure. At the same time, the rotating shaft 412 is rotatably mounted on the support base 411, allowing the clamp 42 to rotate flexibly. The motor 413 drives the rotating shaft 412 to rotate via the first gear 415 and the second gear 416, thereby driving the clamp 42 to rotate and effectively achieving precise control of the clamp 42. The output shaft of the cylinder 414 is connected to the clamp 42 to provide additional clamping force or adjust the position of the clamp 42 to meet the clamping requirements of different workpieces. Furthermore, the meshing transmission between the motor 413 and the gears ensures the accuracy and smoothness of the clamp 42's rotation.
[0050] Please see Figure 1 , Figure 4 as well as Figure 6In some embodiments, a lifting mechanism 50 is provided on the base 10. The lifting mechanism 50 is used to drive the sliding mechanism 20, the rotating mechanism 30 and the picking mechanism 40 to rise or fall along the y-axis direction, which effectively enables the cold chamber picking machine 100 to adjust its height according to the position of the workpiece to adapt to workpieces of different heights and sizes, thereby improving the flexibility of the picking machine and thus improving the picking efficiency of the picking machine.
[0051] Furthermore, the lifting mechanism 50 includes a lifting screw 51, a guide shaft 52, and a first support plate 53. Both the lifting screw 51 and the guide shaft 52 are slidably mounted on the base 10. The first support plate 53 is connected to the end of the lifting screw 51 away from the base 10 and the end of the guide shaft 52 away from the base 10. A sliding mechanism 20 is mounted on the first support plate 53. Through the coordinated use of the lifting screw 51, the guide shaft 52, and the first support plate 53, both the lifting screw 51 and the guide shaft 52 are slidably mounted on the base 10. The design of the lifting screw 51 allows for precise height adjustment through rotation or driving its movement, effectively enabling the first support plate 53 and its components, such as the sliding mechanism 20, the rotating mechanism 30, and the part-picking mechanism 40, to move upwards or downwards as needed, thus adapting to workpieces of different heights or positions. The guide shaft 52 ensures the stability of the first support plate 53 during lifting, effectively preventing tilting or offset during lifting, thereby guaranteeing the stability and accuracy of the overall structure. Furthermore, the combined use of the lifting screw 51 and the guide shaft 52 effectively enhances the rigidity and load-bearing capacity of the lifting mechanism 50. This design enables the lifting mechanism 50 to withstand greater loads while maintaining high-precision lifting movements.
[0052] Please see Figure 1 , Figure 4 as well as Figures 6-8In some embodiments, the sliding mechanism 20 includes a bracket 21, a first servo motor 22, a drag chain 23, and a sliding block 24. The bracket 21 is mounted on a first support plate 53, the first servo motor 22 is mounted on the bracket 21, and the sliding block 24 is slidably mounted on the bracket 21 along the z-axis. A rack 25 is mounted on the bottom of the sliding block 24, and a third gear 26 is mounted on the output shaft of the first servo motor 22. The third gear 26 meshes with the rack 25. A fixing plate is also mounted on the first support plate 53, and an electrical box 60 is mounted on the fixing plate. One end of the drag chain 23 is connected to the electrical box 60, and the other end of the drag chain 23 is connected to the sliding block 24. A rotating mechanism 30 is mounted on the sliding block 24. Through the coordinated use of bracket 21, first servo motor 22, cable chain 23, and sliding block 24, the output shaft of the first servo motor 22 is equipped with a third gear 26. The output shaft of the first servo motor 22 meshes with the rack 25 of the sliding block 24 via the third gear 26, driving the first servo motor 22. The first servo motor 22 drives the sliding block 24 to slide along the z-axis on the bracket 21, effectively enabling the sliding block 24 and its components, such as the rotating mechanism 30 and the picking mechanism 40, to move forward or backward as needed. Simultaneously, the meshing of the rack 25 and the third gear 26 further enhances the stability and reliability of the sliding motion, reducing positioning errors caused by vibration or external force interference. Furthermore, the application of the first servo motor 22 ensures the precise movement of the sliding block 24 on the bracket 21. The servo motor 413, with its high precision and fast response, can achieve precise positioning of the sliding block 24 along the z-axis, improving the degree of automation. The cable chain 23 effectively allows the cables and conduits between the electrical box 60 and the sliding block 24 to extend and retract freely as the sliding block 24 moves, avoiding cable tangling or pulling. This not only ensures stable energy transmission but also improves the overall operating efficiency of the equipment.
[0053] Please see Figure 1 as well as Figure 4In some embodiments, the rotating mechanism 30 includes a second support plate 31, a second servo motor 32, a first rotating rod 33, and a second rotating rod 34. The second support plate 31 is mounted on the sliding block 24. One end of the first rotating rod 33 and one end of the second rotating rod 34 are rotatably mounted on the top of the second support plate 31. The other ends of the first rotating rod 33 and the second rotating rod 34 are both connected to the rotating arm 41. The second servo motor 32 is mounted on the bottom of the second support plate 31, and its output shaft passes through the second support plate 31 and connects to the first rotating rod 33. Through the coordinated use of the second support plate 31, the second servo motor 32, the first rotating rod 33, and the second rotating rod 34, the output shaft of the second servo motor 32 is connected to the first rotating rod 33, effectively ensuring the precise rotation of the first rotating rod 33. The high precision and fast response capability of the servo motor 413 allow for precise control of both the rotation angle and speed. When picking up a part, the second servo motor 32 is driven, which drives the first rotating rod 33 and the rotating arm 41 to rotate. This allows the rotating arm 41 to drive the clamp 42 to rotate, effectively expanding the picking range of the clamp 42 and thus improving the picking efficiency of the cold chamber picking machine 100. At the same time, the second rotating rod 34 assists the rotating arm 41 to rotate, effectively improving the stability of the rotating arm 41 when it rotates.
[0054] Please see Figure 1 as well as Figure 4 In some embodiments, a detection mechanism 70 is also included. The detection mechanism 70 includes a support rod 71, a first sensor 72, and a second sensor 73. The support rod 71 is disposed on one side of the bracket 21, and the first sensor 72 and the second sensor 73 are both disposed on the support rod 71, located above the clamp 42. Through the coordinated use of the support rod 71, the first sensor 72, and the second sensor 73, both located above the clamp 42, the workpiece is effectively detected during pick-up, thereby preventing the clamp 42 from missing or mis-clamping the workpiece.
[0055] Please see Figure 1 , Figure 4 as well as Figure 6 In some embodiments, a protective mechanism 80 is also included. The protective mechanism 80 includes a connecting rod 81 and a protective railing 82. The protective railing 82 is disposed on one side of the first support plate 53 via the connecting rod 81, and a perforated structure 821 is provided on the protective railing 82. The protective railing 82 can effectively prevent the clamping mechanism from colliding with personnel or objects during rotation, thereby improving the safety of the cold chamber retrieval machine 100. The perforated structure 821 on the protective railing 82 facilitates observation by personnel. The protective railing 82 is designed with an "L" shape, which conforms to the overall structure of this utility model and improves its protective performance.
