Description

Technical Field

[0001] This invention belongs to the field of steel ball production technology, specifically relating to a high-chromium alloy steel ball production equipment with automatic clamping function. Background Technology

[0002] Steel balls are classified into ground steel balls, forged steel balls, and cast steel balls according to their manufacturing process. Among them, bearing steel balls are important basic components in industry. The steel balls produced are not used because their surfaces are not smooth. In order to improve the smoothness of the steel ball surface, it is necessary to polish the surface of the steel ball.

[0003] When polishing steel balls, they need to be clamped and fixed. However, existing clamping components usually clamp the steel balls rigidly, which results in greater friction when the steel balls rotate, making it difficult to perform rotational polishing. Furthermore, as the outer diameter of the steel balls decreases, rigid clamping cannot maintain a close fit. In addition, the current methods of controlling the rotation of steel balls are mostly regular rotations, which cannot achieve full coverage of the steel ball surface. Summary of the Invention

[0004] The purpose of this invention is to provide a high-chromium alloy steel ball production equipment with a simple structure and reasonable design and automatic clamping function in order to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A high-chromium alloy steel ball production equipment with automatic clamping function includes a base plate fixing frame, which is fixedly connected to the upper surface of the base plate. A polishing mechanism is installed on the fixing frame through a lifting control mechanism. A table is horizontally arranged above the base plate, and the table is fixedly connected to the base plate through multiple vertically arranged supports. A placement ring groove is fixedly installed in the middle of the table. A movable plate is arranged below the table and movably sleeved on the outer wall of the supports. A rotating ring is rotatably installed on the upper surface of the movable plate. Two connecting shafts are horizontally rotatably installed on the inner wall of the rotating ring. One end of each of the two connecting shafts passes through the rotating ring. An adjusting roller is fixedly sleeved in the middle of the connecting shaft. The two connecting shafts are connected through a transmission mechanism, and one of the connecting shafts is connected to a drive mechanism.

[0006] As a further optimization of the present invention, the lifting control mechanism includes a first electric push rod that is vertically fixedly installed on the upper part of the fixed frame. The free end of the first electric push rod movably passes through the fixed frame, and a U-shaped connecting frame is fixedly installed on the free end of the first electric push rod.

[0007] As a further optimization of the present invention, the polishing mechanism includes a first motor that is laterally rotatably mounted on the outer wall of the connecting frame, the output shaft of the first motor rotatably passing through the connecting frame, and a polishing roller that is fixedly sleeved on the outer wall of the output shaft of the first motor is provided inside the connecting frame.

[0008] As a further optimization of the present invention, the transmission mechanism includes pulleys fixedly installed at one end of two connecting shafts, and the two pulleys are connected by belt drive.

[0009] As a further optimization of the present invention, the driving mechanism includes a second motor that is vertically fixedly installed on the outer wall of the rotating ring, and bevel gears are fixedly installed on the output shaft of the second motor and the end of one of the connecting shafts, and the two bevel gears are meshed together.

[0010] As a further optimization of the present invention, a gate-shaped fixing seat is fixedly installed on the upper surface of the base plate, and a second electric push rod is vertically fixedly installed on the top surface of the fixing seat. The free end of the second electric push rod movably passes through the fixing seat, and a cross plate is fixedly installed on the free end of the second electric push rod. The cross plate is fixedly connected to the inner wall of the moving plate.

[0011] As a further optimization of the present invention, a third motor is horizontally fixedly installed on the upper surface of the movable plate, a worm gear is horizontally fixedly installed on the output shaft of the third motor, and a worm wheel is fixedly sleeved on the outer wall of the rotating ring, with the worm wheel meshing with the worm gear.

[0012] As a further optimization of the present invention, force-bearing blocks are respectively provided on both sides of the placement ring groove and fixedly installed on the upper surface of the table. Clamping members are fixedly installed on the opposite surfaces of the two force-bearing blocks by horizontally arranged telescopic rods, and springs are movably sleeved on the outer wall of the telescopic rods.

[0013] As a further optimization of the present invention, the opposing surfaces of the two clamping members are curved surfaces, and a through groove is provided on the upper surface of the platform, and the clamping members are slidably connected to the inner wall of the through groove.

[0014] The beneficial effects of this invention are as follows: 1. This invention uses a spring in conjunction with a telescopic rod to install the clamping component. The spring pushes the clamping component to ensure that the clamping component and the steel ball are elastically fitted together, so that the friction force received by the steel ball during rotation is reduced. When the outer diameter of the steel ball is reduced due to polishing, the clamping component can automatically adjust to ensure that it fits the steel ball. In addition, the working surface of the clamping component is curved, which improves the fit with the steel ball.

[0015] 2. This invention uses two adjusting rollers that rotate in the same direction to drive the steel ball to rotate, and a third motor indirectly drives the rotating ring to rotate. This causes the self-rotating adjusting rollers to rotate and change their axial direction in the horizontal plane, resulting in irregular rotation of the steel ball. This allows the polishing roller to evenly cover the surface of the steel ball, making the surface of the steel ball smoother and the polishing quality higher.

[0016] 3. The present invention makes the cleaning and collection of metal debris more convenient by using a rotating ring and a moving plate that are suspended in the air. In addition, the rotating ring and the table surface cooperate to cover the worm gear, worm, and bevel gear at the bottom, preventing debris from contacting the transmission components and effectively ensuring the stability of the device's transmission components.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1: As Figures 1-5As shown, a high-chromium alloy steel ball production equipment with automatic clamping function includes a base plate 1 and a fixed frame 2. The fixed frame 2 is fixedly connected to the upper surface of the base plate 1. The fixed frame 2 is equipped with a polishing mechanism through a lifting control mechanism. A table 3 is horizontally arranged above the base plate 1. The table 3 is fixedly connected to the base plate 1 through multiple vertically arranged supports 4. A placement ring groove 5 is fixedly installed in the middle of the table 3. A movable plate 6 is movably sleeved on the outer wall of the support 4 below the table 3. A rotating ring 7 is rotatably installed on the upper surface of the movable plate 6. Two connecting shafts 8 are horizontally rotatably installed on the inner wall of the rotating ring 7. One end of each of the two connecting shafts 8 passes through the rotating ring 7. An adjusting roller 9 is fixedly sleeved in the middle of the connecting shaft 8. The two connecting shafts 8 are connected through a transmission mechanism. One of the connecting shafts 8 is connected to a drive mechanism. The two adjusting rollers 9 are in contact with the lower surface of the steel ball. The rotating adjusting tank 9 continuously drives the steel ball to rotate, and the third motor 20 indirectly drives the adjusting rollers 9 to change direction, causing the steel ball to rotate irregularly. The polishing roller 13 fully covers the surface of the steel ball.

[0021] like Figure 1 As shown, the lifting control mechanism includes a first electric push rod 10 vertically fixedly installed on the upper part of the fixed frame 2. The free end of the first electric push rod 10 moves through the fixed frame 2. A U-shaped connecting frame 11 is fixedly installed on the free end of the first electric push rod 10. The first electric push rod 10 indirectly controls the lifting of the polishing roller 13, so that the polishing roller 13 can be in contact with the surface of the steel ball.

[0022] like Figure 1 As shown, the polishing mechanism includes a first motor 12 that is horizontally rotatably mounted on the outer wall of the connecting frame 11. The output shaft of the first motor 12 rotates through the connecting frame 11. A polishing roller 13 is fixedly sleeved on the outer wall of the output shaft of the first motor 12 inside the connecting frame 11. The first motor 12 drives the polishing roller 13 to rotate and polish the surface of the steel ball.

[0023] like Figure 1 , Figure 2 , Figure 5 As shown, the transmission mechanism includes pulleys 14 fixedly installed at one end of two connecting shafts 8. The two pulleys 14 are connected by a belt 15. The drive mechanism includes a second motor 16 vertically fixedly installed on the outer wall of the rotating ring 7. The output shaft of the second motor 16 and the end of one of the connecting shafts 8 are respectively fixedly installed with bevel gears 17. The two bevel gears 17 are meshed and connected. The second motor 16 indirectly controls the rotation of two adjusting rollers 9. The cooperation between the pulleys 14 and the belt 15 ensures that the two adjusting rollers 9 rotate in the same direction, thereby realizing the rotation adjustment of the steel ball.

[0024] like Figure 1 , Figure 3As shown, a gate-shaped fixed seat is fixedly installed on the upper surface of the base plate 1. A second electric push rod 18 is vertically fixedly installed on the top surface inside the fixed seat. The free end of the second electric push rod 18 moves through the fixed seat. A cross plate 19 is fixedly installed on the free end of the second electric push rod 18. The cross plate 19 is fixedly connected to the inner wall of the moving plate 6. The second electric push rod 19 indirectly controls the height of the adjusting roller 9 to ensure that the adjusting roller 9 can fit against the lower surface of the steel ball.

[0025] like Figure 1 , Figure 2 As shown, a third motor 20 is horizontally fixedly installed on the upper end face of the movable plate 6. A worm gear 21 is horizontally fixedly installed on the output shaft of the third motor 20. A worm wheel 22 is fixedly sleeved on the outer wall of the rotating ring 7. The worm wheel 22 is meshed with the worm gear 21. The third motor 20 is a servo motor. The third motor 20 drives the worm gear 21 to rotate intermittently in the forward and reverse directions. Through the transmission of the worm wheel 22, it indirectly drives the rotating ring 7 to rotate, thereby adjusting the axial direction of the internal adjusting roller 9.

[0026] like Figure 1 , Figure 4 As shown, force-bearing blocks are fixedly installed on the upper surface of the table 3 on both sides of the placement groove 5. Clamping parts 24 are fixedly installed on the opposite surfaces of the two force-bearing blocks through horizontally arranged telescopic rods 23. Springs 25 are movably sleeved on the outer wall of the telescopic rods 23. The telescopic rods 23 and springs 25 push the clamping parts 24 to fit against the steel ball, providing elastic auxiliary fixation for the steel ball. The fit can be automatically adjusted when the outer diameter of the steel ball decreases, ensuring the clamping and fixing effect.

[0027] like Figure 1 , Figure 4 As shown, the opposing surfaces of the two clamping members 24 are curved surfaces, and a through groove is provided on the upper end surface of the platform 3. The clamping member 24 is slidably connected to the inner wall of the through groove. The clamping member 24 is set as a curved surface to increase the fit with the surface of the steel ball and to provide more stable auxiliary fixation for the steel ball.

[0028] It should be noted that in use, this high-chromium alloy steel ball production equipment with automatic clamping function involves pulling open the two clamping parts 24, placing the steel ball in the placement ring groove 5, and the clamping parts 24, pushed by the spring 25, pressing against the steel ball to clamp and fix it. The second electric push rod 18 is then activated, causing the moving plate 6 to move upwards. The moving plate 6 then drives the rotating ring 7 to move upwards, and the adjusting roller 9 moves upwards synchronously with the rotating ring 7 until the adjusting roller 9 is pressed against the steel ball. The second motor 16 then drives the bevel gear 17 directly connected to it to rotate, and indirectly drives the connecting shaft 8 to rotate through its interaction with another bevel gear 17. The connecting shaft 8 is connected to the pulley 1. 4. The belt 15 drives the other connecting shaft 8 to rotate synchronously. The adjusting roller 9 rotates synchronously with the corresponding connecting shaft 8. The rotation of the adjusting roller 9 drives the steel ball to rotate in the placement ring groove 5. The third motor 20 drives the worm 21 to rotate intermittently in both directions. The worm 21 drives the worm wheel 22 to rotate. The rotating ring 7 rotates synchronously with the worm wheel 22, causing the adjusting roller 9 to rotate in the horizontal plane and change direction. The steel ball rotates irregularly in the placement ring groove 5. The first motor 12 works to drive the polishing roller 13 to rotate. The first electric push rod 10 works to drive the connecting frame 11 to move downward, indirectly driving the polishing roller 13 on the connecting frame 11 to move downward. The polishing roller 13 contacts the steel ball to perform polishing.

[0029] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
