Adjustable grinding medium feeding device for steel ball machining

Abstract

The utility model discloses an adjustable grinding medium feeding device for steel ball machining. The adjustable grinding medium feeding device comprises a frame body. The threaded rod is rotated to drive the second plate body, and then the roller body is driven to move. The positions of the grooves in the surface of the roller body are changed along with the change of the position of the roller body. The multiple sets of grooves in the surface of the roller body are designed in a gradient mode and tend to become large gradually from the starting end to the tail end. The amount of the grinding medium entering the grooves is different due to the size difference of the grooves. When the roller body moves to a specific position, only a small amount of grinding medium is allowed to enter the groove with a smaller size, and the roller is suitable for a fine machining stage with a higher grinding precision requirement; and when the roller body moves to the position where the size of the groove is large, more grinding media can be contained, and the requirement of the rough machining stage where materials need to be rapidly removed can be met. In this way, the position of the roller body is adjusted by rotating the threaded rod, and the feeding amount of the grinding medium can be controlled to a certain degree.

Description

Technical Field

[0001] This utility model relates to the technical field of steel ball processing, and in particular to an adjustable grinding media dispensing device for steel ball processing. Background Technology

[0002] Grinding media come in a variety of materials, such as silicon carbide, which possesses high hardness, high wear resistance, and good thermal conductivity. In steel ball grinding, it can quickly remove material, improve grinding efficiency, and is suitable for roughing and semi-finishing stages. For example, in the machining of steel balls for some ordinary mechanical parts where the surface roughness requirements are not extremely high, silicon carbide abrasives can effectively grind the steel ball blank to near the finished product size.

[0003] In the current steel ball processing field, most grinding media dispensing devices use a fixed-size discharge port design. However, in actual production, the steel ball processing technology is complex and precise, with significant differences in the required grinding media dosage at different stages. In the rough grinding stage, to efficiently remove excess material from the steel ball blank, the amount of grinding media added needs to be increased to enhance the grinding intensity. However, in the semi-fine and fine grinding stages, to ensure the steel balls achieve high-precision dimensions and a mirror-like surface finish, the dosage needs to be precisely reduced to avoid over-grinding and workpiece damage. However, fixed-size discharge ports cannot meet these dynamic production needs, forcing operators to passively adjust production processes or change equipment when faced with different process requirements, thus impacting production efficiency to some extent. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable grinding media dispensing device for steel ball processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable grinding media dispensing device for steel ball processing includes a frame. Two sets of plates are connected to one end of the frame. The two sets of plates are rotatably connected to the same set of threaded rods. The threaded rods are threadedly connected to two sets of plates, which are rotatably connected to the same set of rollers. Multiple grooves are formed on the outer wall of the rollers. A third plate is connected to one end of the frame. The threaded rods are rotatably connected to the third plate. A motor is mounted on one end of the third plate. The output end of the motor is connected to a disc. Multiple rods are connected to one end of the disc. A second disc is connected to one end of the rollers. The second disc has multiple sets of holes. The rods are slidably connected to corresponding holes. A hopper is connected to the frame. The rollers are located at and fit into the opening of the hopper. A slide rail is connected to the frame. The dimensions of the multiple rows of grooves decrease sequentially towards the motor.

[0007] Preferably, one end of the slide is arc-shaped and fits the roller body.

[0008] Preferably, baffles are connected to both one end and the other end of the slide.

[0009] Preferably, the slide is V-shaped.

[0010] Preferably, the frame is provided with two sets of sliding grooves, and one end of each of the two sets of plates is connected to two sets of sliders, and the multiple sets of sliders are slidably connected to the corresponding sliding grooves.

[0011] Preferably, a handwheel is connected to one end of the threaded rod.

[0012] Preferably, all of the rods are made of carbon steel.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the cooperation between the threaded rod, plate two, and roller, rotating the threaded rod drives plate two, which in turn moves the roller. As the position of the roller changes, the position of its surface grooves also changes. The multiple sets of grooves on the roller surface adopt a gradient design, gradually increasing in size from the beginning to the end. The amount of abrasive media entering the grooves varies depending on the groove size. When the roller moves to a specific position, the smaller grooves allow only a small amount of abrasive media to enter, suitable for fine machining stages with high grinding precision requirements; while when the roller moves to a position with larger grooves, it can accommodate more abrasive media, meeting the needs of rough machining stages that require rapid material removal. In this way, by rotating the threaded rod to adjust the position of the roller, the amount of abrasive media can be controlled to a certain extent.

[0015] 2. Through the coordination between the motor, disc one, and rod, the motor is started to drive disc one to rotate. Disc one drives disc two to rotate through the rod. Disc two drives the roller to rotate and convey the grinding medium. Because the rod has a certain length reserved, the rod can still drive disc two to rotate after the roller moves, which has a wide range of practical applications. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5An adjustable grinding media dispensing device for steel ball processing includes a frame 1. Two sets of plates 2 are connected to one end of the frame 1. The two sets of plates 2 are rotatably connected to the same set of threaded rods 3. Rotation of the threaded rods 3 causes the second set of plates 4 to move. The threaded rods 3 are threadedly connected to the two sets of plates 4. Movement of the second set of plates 4 causes the movement of rollers 5. The two sets of plates 4 are rotatably connected to the same set of rollers 5. Multiple sets of grooves 15 are formed on the outer wall of the rollers 5. As the rollers 5 move, the positions of the grooves 15 also change. One end of frame 1 is connected to plate 3 6, and threaded rod 3 is rotatably connected to plate 3 6. A motor 7 is installed at one end of plate 3 6; the model of motor 7 can be selected according to actual conditions. The output end of motor 7 is connected to disc 1 8, which drives disc 1 8 to rotate. One end of disc 1 8 is connected to multiple sets of rods 9, which drive the rods 9 to rotate. One end of roller 5 is connected to disc 2 10, which has multiple sets of holes 11. The multiple sets of rods 9 slide in contact with the corresponding holes 11. The rod 9 and the hole 11 work together to drive the disc 10 to rotate, which in turn drives the roller 5 to rotate, conveying the grinding medium in the groove 15. Because the rod 9 has a certain margin, it can still drive the roller 5 to rotate after the roller 5 moves, making it quite practical. The frame 1 is connected to the hopper 12, and the roller 5 is located at one end of the hopper 12 and fits into it. When the roller 5 rotates, it drives the grinding medium in the groove 15 to fall onto the slide 13 and slide down to the processing area. The frame 1 is connected to the slide 13, and the size of the multiple rows of grooves 15 decreases sequentially towards the motor 7. Because the grooves 15 are of different sizes, moving the position of the roller 5 drives the corresponding size groove 15 to move below the outlet of the hopper 12. The larger the size, the more grinding medium enters the groove 15, which can be used for rough processing. Conversely, the smaller the size, the less grinding medium can be used for fine processing. This makes it convenient to adjust the amount of grinding medium added, making it quite practical.

[0024] In this embodiment, one end of the slide 13 is arc-shaped and fits into the roller 5, allowing the grinding media in the groove 15 to smoothly slide onto the slide 13. Baffles 14 are connected to both ends of the slide 13, which to some extent restrict the flow path of the grinding media and prevent it from sliding off the sides of the slide 13. The slide 13 is V-shaped, which helps prevent the grinding media from accumulating within it. Due to the inclination angle of the inclined surfaces on both sides, the grinding media is continuously subjected to a downward force, allowing it to quickly pass through the slide 13, thus reducing blockages caused by accumulation. Two sets of sliding grooves 16 are provided on the frame 1, and two sets of sliders 17 are connected to one end of each of the two sets of plates 4. Multiple sliders 17 are slidably connected to corresponding sliding grooves 16, and the sliding grooves 16 and sliders 17 cooperate to guide the plates 4. A handwheel 18 is connected to one end of the threaded rod 3, making it easier to rotate the threaded rod 3. All of the rods 9 are made of carbon steel. Carbon steel has high strength and hardness, can withstand large torque and impact, and is relatively inexpensive and has good processing performance.

[0025] The working principle of this embodiment is as follows: During use, rotating the threaded rod 3 drives the roller 5 to move through the plate 2 4. Because the size of the groove 15 is designed with gradient, after the roller 5 moves, the size of the groove 15 located below the discharge port of the hopper 12 changes, and the amount of grinding media entering the groove 15 also changes accordingly. More can be used for rough processing, and less can be used for fine processing. To a certain extent, the amount of grinding media can be adjusted according to actual needs, and it has a wide range of applications. The starting motor 7 drives the roller 5 to rotate through the cooperation of the rod 9 and the hole 11 to transport the grinding media. When the roller 5 moves in position under the synergistic action of the threaded rod 3 and the plate 2 4, even if its position changes, the rod 9 has sufficient reserved length to still drive the roller 5 to rotate through the disc 2 10, which has a wide range of applications.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
