Description

Technical Field

[0001] The invention relates to the field of steel ball processing, and more particularly to a polishing device for improving the surface finish of a steel ball. Background Art

[0002] Steel balls are one of the most common parts in industrial production. Steel balls are generally used as rolling elements. Therefore, the surface cleanliness of steel balls is highly required when they are used. Steel balls need to be ground after they are produced. In the prior art, steel ball grinding is mostly done by drum grinding, where steel balls and grinding media (such as abrasives, polishing agents, etc.) are put into the drum together. When the drum rotates, the steel balls collide and rub against each other in the drum, and at the same time come into contact with the grinding media. Under the action of abrasives and polishing agents, the roughness of the steel ball surface is gradually removed to achieve a polishing effect.

[0003] The prior art discloses a rolling polishing device for producing high wear-resistant alloy balls (patent announcement number: CN215547783U). The purpose of polishing is achieved by friction between the internal steel balls and the abrasives through the rotation of the drum. However, the device has the following shortcomings when in use: 1. The drum cannot be kept fixed during loading and unloading, so one person is required to straighten the drum while another person loads and unloads the materials and closes the hatch, resulting in a waste of human resources; 2. There is no fulcrum on the drum surface when the internal steel balls are exported, making operation inconvenient. Summary of the invention

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention. Example 1

[0018] See also Figure 1-Figure 3 As shown, a polishing device for improving the surface finish of a steel ball comprises a frame 1 and a roller 5. The frame 1 is of a structure that is small at the top and large at the bottom to improve the overall stability of the device. A cross frame 2 is laterally fixed to the inner side of the frame 1, and a driving motor 3 is arranged on one side of the upper surface of the cross frame 2. Bearing seats 4 are installed on both sides of the top of the frame 1. The roller 5 is rotatably installed between the two bearing seats 4. The roller 5 is of a horizontally arranged regular hexagonal prism structure. One end of the roller 5 is connected to the output end of the driving motor 3 by a belt transmission mechanism 6, and then the driving motor 3 can drive the roller 5 to rotate. Reinforcing ribs 51 are evenly arranged on both sides of the roller 5 to improve the strength of the roller 5.

[0019] Choose the right grinding media, usually silicon carbide, aluminum oxide, etc. Polishing agents can be pastes or liquids containing micronized abrasives and chemical additives, the chemical composition of which helps to accelerate the removal of surface materials and improve surface finish.

[0020] The rotation speed of the drum 5 is controlled. Generally, the rotation speed should not be too fast to avoid damage caused by excessive collision between the steel balls. It is usually several tens to more than one hundred revolutions per minute.

[0021] Determine a reasonable polishing time. Depending on the initial roughness of the steel ball and the required finish, the polishing time may vary from a few hours to more than ten hours.

[0022] Among them, a discharge port is provided on one side of the outer surface of the drum 5, and the discharge port is provided on one of the six surfaces of the drum 5. A sealing plate 7 for sealing the discharge port is installed on the surface of the drum 5 by bolts, so as to keep the internal seal of the drum 5 rollingly to prevent leakage. A handle 71 is provided on the outside of the sealing plate 7. A limiting cylinder 52 is provided on one side of the drum 5. The limiting cylinder 52 is placed on one side of the drum 5. The limiting cylinder 52 corresponds to the discharge port, and the limiting cylinder 52 and the discharge port are at the same angle relative to the rotation axis of the drum 5. When the discharge port is upward, the limiting cylinder 52 is also placed at the top, and the limiting cylinder 52 is placed between two adjacent reinforcing ribs 51. The limiting cylinder 5 2 ends are open, wherein a support plate 41 is arranged on the top of the bearing seat 4 near the side of the belt transmission mechanism 6, a through hole 42 is opened on the surface of the support plate 41, a slide bar 8 is slidably penetrated inside the through hole 42, the slide bar 8 slides horizontally, a limit bolt 81 is arranged at one end of the slide bar 8, the end of the limit bolt 81 is hemispherical, a pull plate 82 is arranged at the other end of the slide bar 8, the limit bolt 81 is adapted to the inner size of the limit cylinder 52, when the discharge port is vertically upward, the axis of the limit bolt 81 coincides with the axis of the limit cylinder 52, the limit bolt 81 can slide into the inside of the limit cylinder 52, and the pull plate 82 is placed on the outside of the support plate 41, so as to operate the slide bar 8 from the outside.

[0023] Please refer to Figure 2 As shown, a spring 9 is sleeved on the surface of the slide rod 8, and the spring 9 is placed between the limit bolt 81 and the support plate 41. The elastic force of the spring 9 ensures that when the discharge port of the roller 5 is vertically upward, the limit bolt 81 always keeps in cooperation with the limit cylinder 52 to prevent it from falling off.

[0024] Please refer to Figure 3 and Figure 5As shown, a convex strip 83 is provided on the surface of the slide bar 8, and a groove 43 corresponding to the convex strip 83 is provided on the inner side of the through hole 42. The cooperation between the two ensures that the slide bar 8 can only move along the axis. When the drum 5 needs to rotate, the slide bar 8 can be pulled outward to disengage the limit bolt 81 and the limit cylinder 52, and the pulling outward is continued until the convex strip 83 disengages from the groove 43. Only then will the slide bar 8 be rotated to dislocate the convex strip 83 and the groove 43, so that the spring 9 keeps storing force while the limit bolt 81 is placed at the outermost position, which will not affect the reinforcing rib 51.

[0025] Please refer to Figure 1 and Figure 4 As shown, a fixed block 53 is provided on one side of the drum 5, the end of the fixed block 53 is flush with the outer surface of the drum 5, the fixed block 53 and the slide bar 8 are on the same side, and the fixed block 53 is placed on the side of the slide bar 8 away from the rotation axis of the drum 5, the fixed block 53 corresponds to the position of the sealing plate 7, and a handle rod 10 slides through the inside of the fixed block 53, and the handle rod 10 is perpendicular to the rotation axis of the drum 5.

[0026] Among them, a ball head 11 is provided at the end of the handle rod 10 that rotates away from the drum 5, and a limit head 12 is provided at the other end of the handle rod 10. A locking knob 13 for fixing the handle rod 10 is screwed on the surface of the fixed block 53. When the drum 5 rotates, the handle rod 10 can be slid inward to fit tightly against one side of the drum 5 to reduce the protruding distance and prevent the rotation of the drum 5 from being affected. Conversely, when pouring the internal material, the handle rod 10 can be slid outward to the maximum size and fixed by the locking knob 13 to provide a fulcrum for the rotation of the drum 5.

[0027] Please refer to Figure 1 As shown, a material discharging guide plate 14 is installed inside the frame 1 , and the front end of the material discharging guide plate 14 is tilted downward. The material discharging guide plate 14 is placed under the roller 5 to guide the material poured out through the roller 5 .

[0028] Working principle: when loading, first keep the opening of the roller 5 facing upward, and it can be fixed by the cooperation of the limit bolt 81 and the limit cylinder 52. At the same time, due to the presence of the spring 9, the stability of the cooperation between the limit bolt 81 and the limit cylinder 52 can be achieved. After adding steel balls, polishing media and corresponding polishing agents to the inside of the roller 5, the sealing plate 7 is used to seal the opening so that the inside of the roller 5 is in a sealed state. The pull plate 82 is pulled outward to make the limit bolt 81 disengage from the cooperation with the limit cylinder 52. The pull is continued until the convex strip 83 slides out of the groove 43. The pull plate 82 can be rotated to cause the convex strip 83 to be misaligned with the groove 43, so that the spring 9 always maintains the stored force state, and the limit bolt 81 will not affect the rotation of the reinforcing rib 51. Start the drive motor 3 to drive the roller 5 to rotate through the belt transmission mechanism 6 so that the internal steel ball and the polishing medium rub to achieve polishing.

[0029] After polishing, the sealing plate 7 is placed at the top using the above principle to facilitate removal of the sealing plate 7, and then the handle rod 10 is pulled up and locked by the locking knob 13. At this time, the roller 5 can be rotated by holding the ball head 11 to control the rotation angle of the roller 5 during discharging. The poured material will be discharged through the discharging guide plate 14. Conversely, during rotation polishing, the ball head 11 is made to slide downward to reduce its protruding part to prevent impact during rotation.

[0030] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
