Description

Technical Field

[0001] This invention relates to the field of bearing outer ring machining technology, and in particular to a groove grinding device and process for bearing outer rings. Background Technology

[0002] The outer ring of a bearing is a ring-shaped part with one or more grooves. During processing, the grooves are ground to a smooth and delicate finish, making it more aesthetically pleasing and dimensionally more precise.

[0003] Existing bearing outer ring grinding equipment first fixes the bearing outer ring with a fixture, and then runs the grinding tool to grind the groove. When there are two grooves on the bearing outer ring, one groove can only be ground first, and then the bearing outer ring can be flipped over and fixed with a fixture again before processing the other groove. This working method results in low overall processing efficiency. Summary of the Invention

This working method results in low overall processing efficiency.

The bottom end of the worm gear is fixedly connected to the output end of the second motor. The worm wheel is fixedly connected to the left end of the main shaft. The main shaft is rotatably connected to the housing through a bearing. The top end of the worm gear is engaged with the worm wheel.

[0007] Preferably, the clamping assembly includes a clamping box, a cylinder, and a movable plate. The left side of the clamping box is fixedly connected to a rotating shaft. The cylinder is fixedly connected to the inner wall of the left side of the clamping box. The movable plate is fixedly connected to the output end of the cylinder. The right side of the clamping box has four elongated holes. A clamping rod is slidably connected inside the elongated holes. The left end of the clamping rod is located inside the clamping box and has an oblique hole. An L-shaped rod corresponding to the oblique hole is fixedly connected to the right side of the movable plate.

[0008] Preferably, a guide rod is fixedly connected to one side of the inner wall of the elongated hole, one end of the guide rod passes through the clamping rod and is fixedly connected to the other side of the inner wall of the elongated hole, and the guide rod is slidably connected to the clamping rod.

One end of the sliding rod is fixedly connected to the inner wall of the front of the rectangular hole, and the other end of the sliding rod passes through the movable block and is fixedly connected to the inner wall of the back of the rectangular hole. The sliding rod is slidably connected to the movable block.

[0011] Preferably, the grinding assembly includes a grinding motor and a grinding wheel, with the grinding motor mounted on the right side of the movable block and the grinding wheel mounted on the output end of the grinding motor.

[0012] Preferably, the adjustment assembly includes a second electric push rod and a fixed base. The fixed base is fixedly connected to the left side of the movable block, the second electric push rod is installed on the left side of the movable plate, and the telescopic end of the second electric push rod is fixedly connected to the fixed base.

The output end of the pump body is fixedly connected to two connecting pipes. A cooling nozzle is installed at the end of the connecting pipe away from the pump body. The cooling nozzle is installed on the upper surface of the support plate.

[0014] A groove grinding process for the outer ring of a bearing includes the following steps:

[0015] 1. Place the outer ring of the bearing in the upper clamping box, then start the cylinder to extend and drive the movable plate and L-shaped rod to move to the right in the inclined hole. At this time, the clamping rod is squeezed and slides along the guide rod to the middle until the four clamping rods fix the outer ring of the bearing.

[0016] 2. Fill the collection tank with coolant, start the pump to extract the coolant from the collection tank, and then spray it out through the connecting pipe to cool the grinding area.

[0017] Third, start the second motor to drive the worm gear to rotate. During the rotation, the worm gear cooperates with the worm wheel to drive the spindle and the bearing plate to rotate until the outer ring of the bearing is rotated to the grinding assembly at the rear. Then start the first motor to drive the shaft and the outer ring of the bearing to rotate. At the same time, start the grinding motor to drive the grinding wheel to rotate. Then start the first electric push rod to extend and drive the movable plate to move to the left. During the movement, the movable plate can move the grinding wheel to the inside of the outer ring of the bearing. Finally, adjust the assembly to make the grinding wheel close to the outer ring of the bearing to grind the first groove.

[0018] 4. Move the outer ring of the bearing to the lower side. The cooling water at the front grinding assembly will flow to the lower side through the water guide plate for cooling. Then rotate the outer ring of the bearing to the front grinding assembly to grind the second groove of the outer ring of the bearing. Finally, release the clamping assembly to obtain the ground outer ring of the bearing.

[0019] The beneficial effects of this invention are:

[0020] 1. The bearing outer ring groove grinding equipment and process fixes the bearing outer ring with a clamping assembly, and then drives the assembly to rotate so that two grinding assemblies grind the two grooves of the bearing outer ring in sequence. Therefore, the bearing outer ring does not need to be flipped over during processing, which improves processing efficiency.

[0021] 2. The grinding equipment and process for the outer ring of the bearing involves injecting coolant into the collection tank, starting the pump to extract the coolant from the collection tank, and then spraying it out through the connecting pipe to cool the grinding area and prevent the outer ring of the bearing from overheating and deforming.

[0022] 3. The equipment and process for grinding the groove of the bearing outer ring: After the first groove of the bearing outer ring is ground, the drive assembly can rotate the bearing outer ring to the lower side for sufficient time to cool down, and the cooling water at the front grinding assembly will flow to the lower side through the water guide plate, thereby fully reducing the temperature of the bearing outer ring and better enabling the grinding assembly to grind the second groove.
