[0003] The self-closing valve die casting surface polishing device is a special equipment used to polish the surface of self-closing valve die castings (such as ball heads and other parts). Its purpose is to remove defects such as burrs, flash, and oxide scale from the surface of the die castings.

[0004] When polishing ball heads, traditional manual polishing tools can only polish a portion of the curved surface of the ball head because the ball head surface is curved.

Moreover, the manual polishing force will deviate each time the position is changed, resulting in uneven polishing effect. Therefore, a surface polishing device for self-closing valve die castings is proposed to address the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6This utility model provides a surface polishing device for die-cast self-closing valves, including a base 1; characterized in that: multiple sets of support rods 11 are fixedly connected to the end of the base 1; a connecting plate 12 is provided on the top of the base 1; the support rods 11 and the connecting plate 12 are fixedly connected; an electric push rod 13 is fixedly connected to the inner wall of the connecting plate 12; a first motor 14 is fixedly connected to the inner wall of the output end of the electric push rod 13; a clamping mechanism is provided at the output end of the first motor 14; a spherical assembly shell 15 is rotatably connected to the inner wall of the base 1; multiple sets of buffer grooves 16 are opened on the inner wall of the spherical assembly shell 15; an assembly frame 17 is slidably connected to the side wall of the buffer groove 16; an elastic floating mechanism is provided between the buffer groove 16 and the assembly frame 17; a second motor 18 is provided on the inner wall of the assembly frame 17; a drive wheel 19 is fixedly connected to the output end of the second motor 18; a grinding wheel 101 is provided on the outer wall of the drive wheel 19; firstly, the ball head is firmly clamped and fixed by the clamping mechanism to prevent the ball head from shaking. The system then activates the electric push rod 13 to transport the ball head into the spherical assembly shell 15, bringing the ball head into contact with the grinding wheel 101. Subsequently, the external control element activates all the second motors 18, which drive the grinding wheel 101 to rotate rapidly via the drive wheel 19. At this time, the rapid rotation of the grinding wheel 101 polishes the surface of the ball head. Simultaneously, the internal structure of the spherical assembly shell 15 fits snugly against the ball head, and the grinding wheel 101 is circumferentially distributed along the internal structure of the spherical assembly shell 15, maximizing the area of ​​the grinding wheel 101 acting on the ball head and achieving complete coverage of the ball head, thereby increasing the polishing area. During this process, the elastic floating mechanism automatically adjusts the pressure according to the curvature of the ball head surface, improving the polishing uniformity. At the same time, during the polishing process, the first motor 14 is activated to slowly rotate the ball head via the clamping mechanism, allowing the grinding wheel 101 to perform comprehensive polishing of the ball head, avoiding polishing dead corners, and thus improving the polishing degree and uniformity.

[0029] Furthermore, such as Figure 2 , Figure 3As shown, the clamping mechanism includes a connecting rod 2 disposed at the output end of the first motor 14; multiple sets of first spring rods 21 are fixedly connected to the inner side wall of the connecting rod 2; the first spring rods 21 are arranged in a circumferential array; clamping plates 22 are fixedly connected to the ends of the first spring rods 21; before polishing, the ball head is first fixed. First, the worker manually holds the three sets of clamping plates 22 to compress the first spring rods 21 and reduce the circumferential range of their action. Then, the ball head is placed in the horizontal position of the clamping plates 22, and the clamping plates 22 are gradually released. At this time, the first spring rods 21 rebound. Force is applied to clamping plate 22, causing clamping plate 22 to push outward and clamp the ball head. Through the three-way pushing force, the inner ring of the ball head is stably clamped and fixed. At the same time, the three sets of first spring rods 21 set in each direction provide sufficient pushing force to clamping plate 22, which can stabilize the clamping effect on the inner ring of the ball head. Through the three-way elastic pushing clamping mechanism, the installation and removal of the ball head can be conveniently realized, improving efficiency. At the same time, the three-way pushing clamping can stabilize the clamping effect on the ball head, improve clamping stability, and thus reduce the shaking during polishing.

[0030] Furthermore, such as Figure 5 As shown, the elastic floating mechanism includes a second spring rod 3 symmetrically fixed to the inner sidewall of the buffer groove 16; a connecting plate 31 is fixed to the end of the second spring rod 3; the connecting plate 31 is fixedly connected to the assembly frame 17; when the grinding wheel 101 contacts the ball head surface, the second spring rod 3 automatically adjusts the pressure of the grinding wheel 101 according to the surface curvature change and the sliding depth of the assembly frame 17 in the buffer groove 16, reducing the pressure at the protruding part to avoid over-polishing, and moderately increasing the pressure at the concave part to ensure the polishing effect, thus ensuring uniform and stable polishing quality.

[0031] Furthermore, such as Figure 3 As shown, the side wall of the clamping plate 22 is provided with multiple sets of filling grooves 4; the side wall of the filling groove 4 is provided with magnetic blocks 41; when the clamping plate 22 clamps the inner ring of the ball head, the magnetic blocks 41 can generate a magnetic attraction effect with the ball head, thereby improving the fit and stability between the clamping plate 22 and the inner ring of the ball head, and thus improving the clamping force on the ball head.

[0032] Furthermore, such as Figure 2 As shown, a gear ring 5 is fixedly connected to the outer wall of the spherical assembly shell 15; a gear ring 5 is rotatably connected to the end of the base 1; a third motor 51 is fixedly connected to the inner wall of the base 1; a gear disk 52 is provided at the output end of the third motor 51; the gear ring 5 and the gear disk 52 are meshed; during the grinding process of rotating the ball head, the third motor 51 is started to drive the gear disk 52 to rotate, thereby driving the spherical assembly shell 15 to rotate through the gear ring 5. At this time, by rotating the polishing device, a dual rotation mode of the polishing device and the ball head is realized, which increases the polishing area of ​​the ball head, reduces the occurrence of polishing dead corners, and thus improves the polishing effect.

[0033] Furthermore, such as Figure 4 As shown, a storage shell 6 is fixedly connected to the inner wall of the spherical assembly shell 15; the storage shell 6 is connected to the miniature vacuum cleaner 61 through a pipe; a fixing sleeve 62 is fixedly connected to the bottom end of the base 1; the miniature vacuum cleaner 61 is fixedly connected to the inner wall of the fixing sleeve 62; when polishing the ball head, dust will be generated. Due to gravity, the dust will fall to the center of the bottom end of the spherical assembly shell 15. At this time, the storage shell 6 collects the dust and the miniature vacuum cleaner 61 sucks it out. At the same time, the suction force generated by the miniature vacuum cleaner 61 absorbs the dust in the top range of the storage shell 6, achieving a dust removal effect and thus improving the polishing environment.

[0034] Furthermore, such as Figure 5 As shown, a rolling bearing 7 is provided on the inner side wall of the assembly frame 17; the rolling bearing 7 is rotatably connected to the output end of the second motor 18; when the second motor 18 starts to rotate the output rod, the rolling bearing 7 ensures that the rotation trajectory of the output rod is stable, thereby improving the stability during rotation and improving the polishing uniformity.

[0035] Working principle: First, the ball head is firmly clamped and fixed by the clamping mechanism to prevent it from shaking. Then, the electric push rod 13 is activated to transport the ball head into the spherical assembly shell 15, so that the ball head contacts the grinding wheel 101. Subsequently, all the second motors 18 are activated by external control elements, which drive the grinding wheel 101 to rotate rapidly via the drive wheel 19. At this time, the rapid rotation of the grinding wheel 101 polishes the surface of the ball head. At the same time, the internal structure of the spherical assembly shell 15 fits snugly against the ball head, and the grinding wheel 101 is circumferentially distributed along the internal structure of the spherical assembly shell 15, which maximizes the area of ​​the grinding wheel 101 acting on the ball head, thus achieving polishing of the ball head. The ball head is fully enclosed, thus increasing the polishing area. During this process, the elastic floating mechanism automatically adjusts the pressure according to the curvature of the ball head surface, improving polishing uniformity. Simultaneously, during polishing, the first motor 14 is activated, driving the ball head to rotate slowly through the clamping mechanism. This allows the abrasive wheel 101 to perform comprehensive polishing of the ball head, avoiding polishing dead angles and improving polishing degree and uniformity. Before polishing, the ball head is first fixed. The operator manually holds the three sets of clamping plates 22 to compress the first spring rod 21, reducing its circumferential range of action. Then, the ball head is placed in the horizontal position of the clamping plates 22, and the clamping plates 22 are gradually released. At this time, the first spring rod... The rebound force generated by 21 acts on the clamping plate 22, causing the clamping plate 22 to push outward and clamp the ball head. Through the three-directional pushing force, a stable clamping and fixation of the inner ring of the ball head is achieved. Simultaneously, the three sets of first spring rods 21 in each direction provide sufficient pushing force to the clamping plate 22, ensuring a stable clamping effect on the inner ring of the ball head. When the grinding wheel 101 contacts the surface of the ball head, the second spring rod 3 automatically adjusts the pressure of the grinding wheel 101 according to the surface curvature change and the sliding depth of the assembly frame 17 in the buffer groove 16. When the clamping plate 22 clamps the inner ring of the ball head, the magnetic block 41 creates a magnetic attraction effect with the ball head, improving the fit and stability between the clamping plate 22 and the inner ring of the ball head. This allows for grinding while rotating the ball head. During the process, the third motor 51 is started to drive the gear disk 52 to rotate, which in turn drives the spherical assembly shell 15 to rotate through the gear ring 5. At this time, the polishing device is rotated to achieve a dual rotation mode of the polishing device and the ball head, thereby increasing the polishing area of ​​the ball head. When polishing the ball head, dust is generated. Due to gravity, the dust falls to the center of the bottom of the spherical assembly shell 15. At this time, the dust is collected by the collection shell 6 and sucked out by the mini vacuum cleaner 61. At the same time, the suction force generated by the mini vacuum cleaner 61 also absorbs the dust in the top area of ​​the collection shell 6. When the second motor 18 is started to rotate the output rod, the rolling bearing 7 ensures that the rotation trajectory of the output rod is stable.
