Description

Technical Field

[0001] This application relates to the field of grinding, and more specifically, to a ball grinding apparatus. Background Technology

[0002] Ball grinding involves grinding the outer surface of the balls to make them smooth, which helps ensure better bearing performance when the balls are used in bearings.

[0003] However, the conventional method of grinding balls mainly uses the mutual movement of two staggered plates to grind the balls. This method results in a small number of balls being ground each time, and the balls will change their rolling direction multiple times under the action of the two plates, which is not conducive to the long-term high-speed rotation of the balls and results in low grinding efficiency. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] Furthermore, the grinding device also includes a pressure monitoring element; the pressure monitoring element is used to monitor the clamping force of the abutting part against the ball.

[0007] Furthermore, a stop is formed on the lifting seat, and when the abutting part abuts against the ball, the stop at least partially overlaps with the base, so that a shielding area is formed between the lifting seat and the base to prevent oil and debris from leaking out.

[0008] Furthermore, the width of the annular groove matches the diameter of the ball.

[0009] Furthermore, a bottom plate is provided in the annular groove; the bottom plate abuts against the bottom of the annular groove, and the bottom plate and the bottom of the annular groove are detachably connected; the bottom plate matches the annular groove, and when the bottom plate is disassembled, the bottom plate abuts against the inner wall of the annular groove.

[0010] Furthermore, a plurality of flexible rods are provided on the base plate, the flexible rods are located on the edge of the base plate, and the flexible rods are located in the annular groove.

[0011] The beneficial effects of this application are as follows:

[0012] By utilizing the continuous rolling of balls in an annular groove along one direction, the balls can maintain high-speed rolling for a long time, thus improving grinding efficiency. Attached Figure Description

[0028] Reference Figures 1-5 ,

[0029] A ball grinding device includes: a base 1, a lifting seat 2, and a driving component.

[0030] The base 1 forms multiple annular grooves 11 for accommodating balls. The lifting seat 2 forms multiple abutting portions that abut against the balls. Each abutting portion is a plate protruding relative to the lifting seat 2, and its shape matches the annular groove 11. A driving component is used to move the lifting seat 2 until the abutting portion abuts against the balls, and to rotate the base 1 relative to the lifting seat 2 when the abutting portion abuts against the balls. The balls are placed into the annular grooves 11, which can accommodate multiple balls. Therefore, during the rotation of the base 1, the abutting portions abut against the balls, allowing the balls to rotate within the annular grooves 11. Rolling friction between the balls and the inner wall of the annular groove 11, as well as rolling friction with the abutting portions, enables the grinding of a large number of balls, resulting in a fast grinding speed.

[0031] Specifically, the grinding device also includes a fixed frame 3. The fixed frame 3 is used to mount the base 1, the lifting seat 2, and the driving component. The base 1 is rotatably connected to the fixed frame 3, and the lifting seat 2 is slidably engaged with the fixed frame 3. The driving component includes a drive motor and a drive hydraulic cylinder 5. Both the drive hydraulic cylinder 5 and the drive motor are mounted on the fixed frame 3. The drive hydraulic cylinder 5 is used to move the lifting seat 2 up and down, so that the abutment part of the lifting seat 2 is pressed against the ball bearings. The drive motor is used to drive the base 1 to rotate.

[0032] Specifically, the grinding device further includes a pressure monitoring element 4; the pressure monitoring element 4 is used to monitor the clamping force of the abutting part against the ball. The pressure monitoring element 4 is a pressure gauge, which is set between the driving hydraulic cylinder 5 and the lifting seat 2. That is, the driving hydraulic cylinder 5 drives the lifting seat 2 to move through the pressure gauge. Therefore, when the abutting part of the lifting seat 2 is pressed against the ball, the pressure gauge displays the clamping force of the abutting part against the ball.

[0033] Specifically, the lifting seat 2 also has a baffle 21. When the abutting part abuts against the ball, the baffle 21 at least partially overlaps with the base 1, so that a shielding area is formed between the lifting seat 2 and the base 1 to prevent oil and debris from leaking out. The baffle 21 is an annular plate, and the baffle 21 partially overlaps with the base 1, thereby sealing the gap between the base 1 and the lifting seat 2, thus preventing oil and grinding debris in the annular groove 11 from being thrown outward, and better protecting the working environment.

[0034] Specifically, the width of the annular groove 11 matches the diameter of the ball. This allows for better polishing of the ball.

[0035] Specifically, a base plate 12 is provided in the annular groove 11; the base plate 12 abuts against the bottom of the annular groove 11, and the base plate 12 and the bottom of the annular groove 11 are detachably connected; the base plate 12 matches the annular groove 11, and when the base plate 12 is disassembled, the base plate 12 is pressed against the inner wall of the annular groove 11. A slot 13 is provided at the bottom of the annular groove 11, and a plug 14 matching the slot 13 is formed on the base plate 12. When the base plate 12 is placed into the annular groove 11, the plug 14 is inserted into the slot 13, thereby fixing the base plate 12 to the bottom of the annular groove 11. When it is necessary to disassemble the base plate 12, simply pull the base plate 12 outward, and the plug 14 disengages from the slot 13, thus completing the disassembly. Since the base plate 12 abuts against the inner wall of the annular groove 11, when the base plate 12 is removed, the base plate 12 will scrape away the debris adhering to the inner wall of the annular groove 11, thereby cleaning the annular groove 11.

[0036] Specifically, a plurality of flexible rods 15 are provided on the base plate 12. The flexible rods 15 are located on the edge of the base plate 12 and are situated in the annular groove 11. During grinding, debris is generated. The function of the flexible rods 15 is to promptly contact the ball bearings, causing the debris to detach from the ball bearings, thereby preventing the debris from adhering to the ball bearings. During ball bearing grinding, the debris and the ball bearings undergo frictional welding, which better ensures the grinding quality. The flexible rods 15 are brush rods.

[0037] Preferably, the driving component also includes a cylinder, which is used to move the base plate 12 up and down. The cylinder moves the base plate 12 up to the outside of the annular groove 11, making the base plate 12 easy to disassemble.
