Description

Technical Field

[0001] This utility model relates to the field of steel ball processing technology, specifically a ball grinding machine for steel ball processing. Background Technology

[0002] Ball bearings are essential basic components of various mechanical equipment, and the steel balls are the key parts of ball bearings, playing a crucial role. Steel ball processing is divided into polishing, grinding, and lapping, with corresponding equipment including polishing machines, grinding machines, and lapping machines, respectively. Lapping machines use high-speed rotation to smooth the surface of the steel balls during processing.

[0003] Chinese patent provides a high-efficiency ball grinding machine for steel ball processing, publication number CN220330870U, which includes a support base, a protective cover tightly attached to the lower end face of the support base, fixing blocks fixedly welded to both sides of the protective cover, screws sleeved inside the fixing blocks, buffer rubber fixedly welded to the lower end of the protective cover, a dust suction pipe sleeved and welded to one side of the protective cover, a hydraulic cylinder fixedly installed on the lower end face of the support base, and a base fixedly connected to the lower end of the hydraulic cylinder.

[0004] Although the device is equipped with a ball grinding tool that can grind steel balls, it can only grind steel balls of the same diameter and cannot be adapted to different types of steel balls, resulting in poor applicability. Furthermore, it can only grind the upper half of the ball, and the lower half needs to be stopped, repositioned, and then restarted to grind the remaining part, which is inefficient.

[0005] Therefore, there is a need to provide a ball grinding machine for steel ball processing. Utility Model Content

[0006] The purpose of this invention is to provide a ball grinding machine for steel ball processing, so as to solve the problems of poor adaptability and low grinding efficiency mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a ball grinding machine for steel ball processing, comprising a base plate and a top plate, a side plate fixedly installed on the top surface of the base plate, a diameter adjustment mechanism fixedly installed on the side surface of the side plate, and an adaptive grinding mechanism fixedly installed on the bottom surface of the top plate; the adaptive grinding mechanism includes a drive motor, the side of the drive motor being fixedly connected to the top plate via a fixing member, an mounting plate fixedly installed on the end face of the drive motor transmission rod, an mounting block fixedly installed on the bottom surface of the mounting plate, a second cylinder fixedly installed on the bottom surface of the mounting block, a third cylinder fixedly installed on the bottom surface of the mounting block, a first hinge fixedly installed on the end face of the push rod of the second cylinder, a first grinding block fixedly installed on the bottom surface of the first hinge, a connecting block fixedly installed on the end face of the push rod of the third cylinder, a second hinge fixedly installed on the bottom surface of the connecting block, and a second grinding block fixedly installed on the bottom surface of the second hinge.

[0008] Preferably, a placement block is fixedly installed on the side of the second grinding block, and a return spring is fixedly installed on the end face of the placement block, with the end face of the return spring being fixedly connected to the side of the connecting block.

[0009] Preferably, the diameter adjustment mechanism includes a fixing block, the side of the fixing block is fixedly connected to the side of the side plate, and a first cylinder is fixedly installed on the side of the fixing block.

[0010] Preferably, a servo motor is fixedly mounted on the side of the side plate by a fastener, and a motor wheel is fixedly mounted on the side of the servo motor transmission rod.

[0011] Preferably, a mounting bracket is fixedly installed on the end face of the first cylinder push rod, and a pin is rotatably mounted on the side of the mounting bracket via a bearing sleeve. A rubber wheel is fixedly installed on the side of the pin, and a driven wheel is fixedly installed on the side of the pin.

[0012] Preferably, a belt is installed in contact with the side of the driven wheel, and the inner wall of the belt is in contact with the side of the motor wheel.

[0013] Preferably, a mounting plate is fixedly installed on the top surface of the side plate, a support rod is fixedly installed on the top surface of the mounting plate, and a top plate is fixedly installed on the top surface of the support rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) This steel ball grinding machine places the steel ball to be ground on a rubber wheel. The second cylinder is opened to push the first grinding block down to contact the steel ball to be ground. The third cylinder is opened to push the connecting block down. At this time, the return spring pushes the placement block and the second grinding block to deflect around the second hinge, pushing the second grinding block to the surface of the steel ball to be ground and making it fit against it. Then, the drive motor is turned on to drive the mounting plate, the first grinding block and the second grinding block to rotate, and perform grinding operations on the steel ball. During grinding, the servo motor is turned on and drives the driven wheel to rotate through the belt, which in turn drives the rubber wheel to rotate. Through the six rubber wheels and the matching transmission system, the contact surface between the steel ball and the first grinding block and the second grinding block can be adjusted, so as to achieve the purpose of adjusting the grinding position without stopping the machine, thereby improving the grinding efficiency of the steel ball.

[0016] 2) When the steel ball grinding machine is used to grind steel balls of different sizes, the first cylinder is opened to push the mounting frame to move, which in turn pushes the rubber wheel to move. By adjusting the distance between the two corresponding rubber wheels, it can adapt to steel balls of different sizes. The first and second hinges are adapted to the size of the steel ball to adjust the contact angle. The return spring makes the second grinding block fit tightly with the steel ball, thus achieving the purpose of grinding steel balls of different sizes. This can improve the applicability and grinding efficiency of the device. Attached Figure Description

[0026] Specifically, in use, first adjust the spacing between the six rubber wheels 306, place the steel ball to be polished on the rubber wheels 306, then open the second cylinder 704 to push the first hinge 705 and the first polishing block 706 down to contact the steel ball to be polished.
