Technical Field
[0001] This utility model relates to the field of bearing manufacturing technology, and in particular to an ultra-precision mechanism for bearing roller ball base surface. Background Technology
[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Early linear motion bearings consisted of a row of wooden rods placed under a row of skids. Modern linear motion bearings use the same working principle, except that sometimes balls are used instead of rollers. The simplest rotary bearing is the bushing bearing, which is a bushing sandwiched between a wheel and an axle.
[0003] In the prior art, the rollers in the bearing play an important role in the rotation of the inner and outer rings of the bearing. The precision of the rollers affects the normal operation of the bearing. When grinding the rollers, most grinding mechanisms are fixed, which has poor flexibility and is not conducive to the device achieving good grinding precision. During grinding, the grinding angle needs to be adjusted manually multiple times, which affects the working efficiency of the grinding mechanism. Therefore, in order to solve the above problems, this utility model proposes an ultra-precision mechanism for the bearing roller ball base surface. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an ultra-precision mechanism for the bearing roller ball base surface. Through the cooperation of a hydraulic rod and a motor, the grinding block is made to fit the roller surface, enhancing the flexibility of the grinding mechanism. The grinding angle of the grinding block can be adjusted by an electric push rod, which improves the grinding accuracy of the lifting device. The grinding angle can be adjusted in time under the scanning of an infrared measuring instrument, which helps to improve the working efficiency of the grinding mechanism.
[0005] This utility model provides the following technical solution: a bearing roller ball base surface ultra-precision mechanism, including a base plate, a support frame fixedly installed on the upper part of the base plate, two support frames symmetrically distributed front and back, a hydraulic rod fixedly installed on the upper part of the support frame, a movable plate fixedly installed on the telescopic end of the hydraulic rod, a groove opened on the right side of the movable plate, a motor fixedly installed on the rear of the movable plate, a threaded rod fixedly installed on the output shaft of the motor, the threaded rod having threads symmetrically distributed front and back, the threaded rod being movably sleeved in the groove, and two sliders movably sleeved on the threaded rod. The slider is symmetrically distributed, with a connecting arm fixedly installed on its right side. The right end of the connecting arm is movably connected to a connecting plate via a shaft. The front and rear parts of the connecting arm are respectively movably connected to electric push rods via shafts. The telescopic ends of the two electric push rods are movably connected to the left side of the connecting plate via shafts. A grinding block is fixedly installed on the right side of the connecting plate. An infrared measuring instrument is fixedly installed on the upper part of the moving plate. Through the cooperation of a hydraulic rod and a motor, the grinding block is made to fit against the roller surface, enhancing the flexibility of the grinding mechanism. The grinding angle of the grinding block can be adjusted in time by the electric push rods, which promotes the grinding accuracy of the lifting device and helps to improve the working efficiency of the grinding mechanism.
[0006] Preferably, a support base is fixedly installed on the upper part of the base plate and directly to the right of the support frame. A second motor is fixedly installed on the upper part of the support base. A rotating plate is fixedly installed on the output shaft of the second motor. A vacuum suction cup is movably connected to the left side of the rotating plate via a shaft. There are two vacuum suction cups, which are symmetrically distributed front and back. The rollers are adsorbed and fixed by the vacuum suction cups, so that the device can fix rollers of different sizes, avoiding the need to change the fixing device back and forth, which helps to improve the applicability of the device.
[0007] Preferably, a water tank is fixedly installed on the upper part of the base plate and between the support frame and the support seat. A pump is fixedly installed on the upper part of the water tank, and a water supply pipe is fixedly installed on the upper part of the pump. A nozzle is fixedly installed at the other end of the water supply pipe. During the grinding process, water is sprayed onto the roller through the nozzle to cool it down, so as to avoid the ball from deforming due to high temperature. At the same time, the powder and debris generated during grinding are washed away to prevent the debris from remaining on the surface of the roller and causing adverse effects on the grinding.
[0008] Preferably, a water inlet is provided on the upper part of the water tank and directly to the left of the pump, and a water collection tank is fixedly installed on the upper part of the base plate and directly below the nozzle. A drain pipe is fixedly connected to the front of the water collection tank. The water collection tank collects water carrying dust and debris, preventing a large amount of dust from polluting the working environment of the device during grinding. At the same time, it facilitates the recycling of water and avoids waste of water resources.
[0009] Compared with the prior art, the advantages of this utility model are as follows:
[0010] 1. The hydraulic rod drives the moving plate to the left side of the roller, and the motor drives the slider to move, thereby moving the grinding block to the appropriate position so that the grinding block contacts the roller surface. This greatly enhances the flexibility of the grinding mechanism. By adjusting the extension distance of the electric push rods on the front and rear sides of the connecting arm, the angle of the connecting plate is changed, which helps the grinding block to obtain a better grinding angle and effectively improves the grinding accuracy of the device. The grinding angle can be adjusted in time under the scanning of an infrared measuring instrument, which effectively improves the working efficiency of the grinding mechanism.
[0011] 2. The rollers are adsorbed and fixed by a vacuum suction cup, allowing the device to fix rollers of different sizes, avoiding the need to change the fixing device repeatedly, which improves the applicability of the device. During the grinding process, a pump pumps clean water from the water tank, and the water flows out through the water pipe and from the nozzle to cool the rollers during grinding, preventing the rollers from deforming due to high temperature. At the same time, it washes away the powder and debris generated during grinding, preventing the debris from remaining on the roller surface and causing adverse effects on grinding, and preventing a large amount of dust from polluting the working environment of the device during grinding.

The sliders 8 are connected by the connecting arm 9 and drive the grinding block 12 to move to the appropriate position, so that the grinding block 12 contacts the surface of the roller, which enhances the flexibility of the grinding mechanism.

The sliders 8, connected by the connecting arm 9, drive the polishing block 12 to move, making the polishing block 12 contact the roller surface. Adjust the front and rear sides of the connecting arm 9. The extension distance of the electric actuator 11 changes the angle of the connecting plate 10, making it easier for the grinding block 12 to obtain a better grinding angle.
