[0012] By means of the above technical solution, the present invention provides a water cooling device for alloy castings after hot-dip galvanizing, which has at least the following beneficial effects compared with the prior art:

[0013] 1. The present invention cools the alloy casting quickly and stably by arranging a spoiler mechanism and a clamping mechanism to cooperate with each other. The alloy casting is stably clamped by the clamping mechanism and placed in a cold water tank. At the same time, the spoiler mechanism is driven to operate, thereby stirring the cooling water in the cold water tank to flow rapidly, which is beneficial to accelerate the cooling speed of the alloy casting, better control the thickness and uniformity of the casting coating, improve the quality and performance of the alloy casting, shorten the cooling time of the casting, reduce the cooling efficiency of the alloy casting, and avoid the situation where the current water cooling device clamps the casting and it is easy to fall into the water when it is shaken or swung, and it needs to be fished out, which wastes time.

[0014] 2. The present invention sets a linkage component to synchronously drive multiple connected vertical rods to drive the clamping blocks at the bottom thereof to move toward the middle, thereby clamping the alloy casting. Alloy castings of different sizes can be stably clamped, thereby expanding the use range of the water cooling device. At the same time, the contact surface between the clamping block and the casting is set to a concave and convex surface, thereby increasing the friction between the clamping block and the casting and improving the stability of clamping the casting.

[0015] 3. When the clamping block contacts the casting, the reaction force pushes the clamping block, and the clamping block squeezes the buffer spring. The buffer spring produces elastic deformation and is compressed, providing a buffering effect for the clamping block, which can effectively reduce the impact and extrusion of the casting during the clamping process, prevent damage or deformation of the casting surface, and reduce the impact force and wear generated during the clamping process, thereby extending the service life of the clamping block.

[0016] 4. The present invention limits the top position of the alloy casting by setting a limit assembly. When the alloy casting is immersed in cooling water, the cooling water will provide upward resistance to the casting. In the process of clamping the casting, the anti-fall-off block is pushed to contact the top of the casting through the transmission structure, so as to press the top of the casting to prevent the casting from falling off due to excessive upward resistance and affecting the subsequent water cooling process, thereby improving the stability of the water cooling process of the casting and improving the practicability of the water cooling device.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] First embodiment

[0032] After the hot-dip galvanizing process, alloy castings are usually cooled by water cooling devices. At present, in order to speed up the cooling speed of the castings, the castings are shaken or swung in the cooling water, but this is easy to shake the castings into the cooling water tank. After cooling, they need to be fished out before entering the next process, resulting in a waste of time. In order to save cooling time and improve the cooling efficiency of alloy castings, refer to Figure 1 - Figure 6The present embodiment provides a water cooling device for alloy castings after hot-dip galvanizing, which is composed of a cold water tank 1, a mechanical arm 2, a clamping mechanism 4 and a spoiler mechanism 3. The mechanical arm 2 is arranged on one side of the cold water tank 1 and is used to clamp the alloy castings that need water cooling. The clamping mechanism 4 is arranged on the output shaft of the mechanical arm 2 and is used to clamp the alloy castings and put them into the cold water tank 1 for cooling. The spoiler mechanism 3 is arranged on the inner side of the cold water tank 1 and is used to stir the cooling water flow to accelerate the cooling of the alloy castings, and the clamping mechanism 4 drives the spoiler mechanism 3 to operate when it moves downward. The temperature of the cooling water is generally controlled between 25 and 50°C. This temperature range helps to optimize the cooling effect and prevent the castings from being overheated or overcooled, thereby ensuring the uniformity and adhesion of the galvanized layer.

[0033] Specifically, the clamping mechanism 4 includes a connecting shell 41 fixedly installed at the bottom of the end effector of the robot arm 2, and three connecting vertical rods 42 arranged at the bottom of the connecting shell 41 and distributed in a circular array. A clamping block 43 is arranged at the bottom of the connecting vertical rod 42, and an uneven surface is arranged on the side of the clamping block 43 that contacts the casting to increase the friction between the clamping block 43 and the casting and improve the stability of clamping the casting. A sliding groove 44 is provided at one end of the clamping block 43, and the connecting vertical rod 42 passes through the sliding groove 44 and is slidably connected thereto. A buffer spring 45 located in the sliding groove 44 and fixed to the clamping block 43 is fixed on one side of the bottom of the connecting vertical rod 42. The buffer spring 45 provides a buffering effect for the clamping block 43, which can effectively reduce the impact and extrusion on the casting during the clamping process and prevent damage or deformation to the surface of the casting.

[0034] Specifically, the spoiler mechanism 3 includes movable vertical rods 31 respectively arranged at the bottom of the three connecting vertical rods 42, and a movable vertical pipe 32 arranged at the bottom of the movable vertical rod 31 and rotating with the cold water tank 1 through a sealed bearing, a stirring wheel 33 is fixed to the outer side of the bottom of the movable vertical pipe 32, and the upper end inner wall of the movable vertical pipe 32 is integrally formed with a screw thread connected to the bottom thread of the movable vertical rod 31, the lower end inner wall of the movable vertical pipe 32 is set as a smooth inner wall, the bottom of the movable vertical rod 31 is rotatably provided with a connecting vertical shaft 34, and the bottom end of the connecting vertical shaft 34 is sealed and slidable in the movable vertical pipe 32, and the bottom of the connecting vertical shaft 34 is fixed with a reset spring 35 fixed to the movable vertical pipe 32. When the movable vertical rod 31 moves downward, it drives the connecting vertical shaft 34 to move downward, and the bottom end of the connecting vertical shaft 34 slides on the inner side of the movable vertical pipe 32, and the connecting vertical shaft 34 squeezes the reset spring 35, and the reset spring 35 is elastically deformed and compressed.

[0035] When the three clamping blocks 43 move downward, the clamping blocks 43 push the movable vertical rod 31 to move downward. Since the bottom of the movable vertical rod 31 is threadedly connected to the upper end of the movable vertical pipe 32, the movable vertical rod 31 drives the movable vertical pipe 32 at its bottom to rotate, and the movable vertical pipe 32 drives the stirring wheel 33 to rotate. The stirring wheel 33 drives the cooling water in the cold water tank 1 to flow, thereby accelerating the cooling speed of the casting, better controlling the thickness and uniformity of the casting coating, improving the quality and performance of the alloy casting, and shortening the cooling time of the casting.

[0036] Second embodiment

[0037] In order to stably clamp alloy castings of different sizes, the use range of the water cooling device is expanded, and the impact and extrusion of the castings during the clamping process can be effectively reduced to prevent damage or deformation of the casting surface. Figure 4 In this embodiment, a linkage assembly 46 for synchronously driving the three connecting vertical rods 42 to move toward the middle is provided on the connecting shell 41. Specifically, the linkage assembly 46 includes three strip-shaped slide grooves 461 arranged in a circumferential array on the bottom wall of the connecting shell 41, the top of the connecting vertical rod 42 passes through the connecting shell 41 and is slidably connected to the strip-shaped slide groove 461, and racks 462 are respectively fixed to the tops of the three connecting vertical rods 42 and located on the inner side of the connecting shell 41, and one end of the three racks 462 is respectively meshed and connected with a gear 463, and the gear 46 A vertical shaft 1 464 is fixed at the axis center of the connecting housing 41 and rotates with the connecting housing 41 through a bearing. A transmission gear ring 465 meshing with the gear 463 is rotatably arranged inside the connecting housing 41. The rack 462 and the transmission gear 463 are arranged to be staggered up and down to ensure that the rack 462 can move stably. A vertical shaft 2 466 is fixed at the axis center of the transmission gear ring 465, and the two ends of the vertical shaft 2 466 respectively penetrate the two sides of the connecting housing 41 and extend to the outside thereof. A driving assembly 468 for driving the vertical shaft 2 466 to rotate is arranged at the top of the connecting housing 41. The driving assembly 468 includes a servo motor 4681 fixedly mounted on the top of the connecting housing 41, a worm 4682 is fixed on the output shaft of the servo motor 4681, and a worm wheel 4683 fixed to the top of the vertical shaft 2 466 is meshed and arranged on one side of the worm 4682.

[0038] By starting the servo motor 4681, the output shaft of the servo motor 4681 drives the vertical shaft 2 466 to rotate through the worm 4682 and the worm wheel 4683, and the vertical shaft 2 466 drives the transmission gear ring 465 to rotate. The transmission gear ring 465 simultaneously drives the three gears 463 to rotate, and the three gears 463 respectively drive the racks 462 meshing therewith to move, and the rack 462 drives the connecting vertical rod 42 at one end thereof to slide inside the strip slide groove 461, and the connecting vertical rod 42 drives the clamping block 43 at its bottom to move, and the three clamping blocks 43 clamp and fix the alloy casting.

[0039] Third embodiment

[0040] In order to limit the top position of the alloy casting, prevent the casting from falling off due to excessive upward resistance and affecting the subsequent water cooling process, and improve the stability of the casting water cooling process, refer to Figure 6 In this embodiment, a limit assembly 467 for limiting the top position of the alloy casting is provided at the bottom of the connecting shell 41. The specific implementation method is that the limit assembly 467 includes a threaded vertical shaft 4671 fixed to the bottom end of the vertical shaft 466, and a connecting vertical pipe 4672 threadedly arranged at the bottom of the threaded vertical shaft 4671, a supporting vertical frame 4673 fixed to the bottom of the connecting shell 41 is slidably arranged at the bottom of the connecting vertical pipe 4672, a connecting spring 4674 is fixedly arranged at the bottom of the connecting vertical pipe 4672, and an anti-slip block 4675 is fixedly arranged at the bottom of the connecting spring 4674.

[0041] When the second vertical shaft 466 rotates, the threaded vertical shaft 4671 at its bottom is driven to rotate, and the threaded vertical shaft 4671 drives the connecting vertical pipe 4672 to move downward, and the connecting vertical pipe 4672 pushes the anti-slip block 4675 to move downward through the connecting spring 4674, and the bottom of the anti-slip block 4675 contacts the top of the casting to limit the casting, thereby pressing the top of the casting to prevent the casting from falling off due to excessive upward resistance, affecting the subsequent water cooling process, thereby improving the practicability of the water cooling device.

[0042] During the actual use of the water cooling device, the clamping mechanism 4 on the output shaft of the robot arm 2 is first moved to the top of the alloy casting that needs water cooling, and the servo motor 4681 is started at the same time. The servo motor 4681 starts to operate, and the output shaft of the servo motor 4681 drives the worm 4682 to rotate, and the worm 4682 drives the worm wheel 4683 engaged with it to rotate, and the worm wheel 4683 drives the vertical shaft 2 466 at its axis to rotate, and the vertical shaft 2 466 drives the transmission gear ring 465 at its axis to rotate, and the transmission gear ring 465 simultaneously drives the three gears 463 to rotate, and the three gears 463 respectively drive the rack 462 engaged with them to move, and the rack 462 drives the connecting vertical rod 42 at one end thereof to slide inside the strip slide groove 461, and the connecting vertical rod 42 drives the clamping block 43 at its bottom to move, and the three clamping blocks 43 clamp and fix the alloy casting.

[0043] At the same time, the second vertical shaft 466 drives the threaded vertical shaft 4671 at its bottom to rotate, and the threaded vertical shaft 4671 drives the connecting vertical pipe 4672 to move downward. The connecting vertical pipe 4672 pushes the anti-slip block 4675 to move downward through the connecting spring 4674. The bottom of the anti-slip block 4675 contacts the top of the casting to limit the alloy casting.

[0044] Then the robotic arm 2 moves the clamped alloy casting to the top of the cold water tank 1 and moves downward, so that the three clamping blocks 43 move downward at the same time, and the clamping blocks 43 push the movable vertical rod 31 at its bottom to move downward, and the movable vertical rod 31 drives the movable vertical pipe 32 at its bottom to rotate, and the movable vertical pipe 32 drives the stirring wheel 33 to rotate, and the stirring wheel 33 drives the cooling water in the cold water tank 1 to flow, thereby accelerating the cooling speed of the casting and shortening the cooling time of the casting.
