[0002] Bearings are an important component in mechanical equipment. Their main function is to support mechanical rotating bodies and reduce the friction coefficient during their movement. When machining the inner circle of a bearing, the inner circle of the bearing needs to be fixed. The Chinese utility model patent with the prior art publication number CN215700262U proposes a bearing fixing device for a bearing inner circle machining grinder. The bearing fixing device is provided with a fixing mechanism and a clamping cylinder.

[0008] Preferably, it also includes a vertical rod, a roller and a spring. The upper end surface of the arc baffle is an inclined surface. The end of the arc baffle away from the positioning block is lower than the end close to the positioning block. The vertical rod is vertically installed on the end of the arm toward the arc baffle.

The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0020] Example 1

[0021] like Figures 1 to 6 As shown, a bearing fixing device for bearing inner circle processing includes a base plate 1 and two positioning blocks 2; it also includes a motor 3, an arm 4, a push block 5, an electromagnet 6 and an arc-shaped slide 7. The arc-shaped slide 7 is set on the base plate 1, the motor 3 is installed on the base plate 1, the motor 3 is located at the center of the arc-shaped slide 7, one end of the arm 4 is connected to the output shaft of the motor 3, and two push blocks 5 are installed on the side wall of the other end of the arm 4. The two push blocks 5 are located in the arc-shaped slide 7. Electromagnets 6 are installed on the opposite surfaces of the two push blocks 5. The two push blocks 5 are respectively opposite to the two positioning blocks 2, and the two positioning blocks 2 are located at one end of the arc-shaped slide 7; it also includes an adjustment slide 8 and a locking bolt 9. The base plate 1 is provided with an adjustment slot The slide 8, the adjustment slide 8 is located at one end of the arc-shaped slide 7, the two positioning blocks 2 are slidably installed in the adjustment slide 8, and the two positioning blocks 2 are provided with locking bolts 9, which are used to lock the positioning block 2 with the adjustment slide 8; it also includes a support column 21, an electromagnet 22, a screw assembly 23, a cross plate 24 and a pressure rod 25, the support column 21 is vertically installed on the base plate 1, the support column 21 is located on the side away from the positioning block 2, the lower end of the support column 21 is provided with an electromagnet 22, the screw assembly 23 presses the cross plate 24 to be installed on the top of the support column 21, the pressure rod 25 is located on the inner side of the support column 21, the pressure rod 25 is located above the arc-shaped slide 7, and the upper end of the pressure rod 25 is installed on the cross plate 24.

[0022] During operation, the two positioning blocks 2 are moved along the adjusting slot 8 to adjust the positions of the two positioning blocks 2, and the two positioning blocks 2 are locked on the adjusting slot 8 by tightening the two locking bolts 9, so as to fix the inner circles of bearings of different diameters. The base plate 1 is installed on the grinding machine. At this time, the positioning block 2 is located on the inner side of the main shaft of the grinder, and one end of the arc slot 7 extends out of the outer side of the main shaft of the grinder. After the inner circles of multiple bearings are concentrically aligned and stacked, they are sleeved on the pressure rod 25. The pressure rod 25 presses the outer walls of the inner circles of multiple bearings tightly against the inner wall of the supporting column 21 from the inside. The electromagnet 22 is energized to adsorb the inner ring of the bearing at the bottom, completing the loading of multiple bearing inner circles. When loading is required, the arm 4 rotates to the side of the supporting column 21 away from the positioning block 2, and the electromagnet The power is cut off for the second 22, causing the inner circle of the lowest bearing to fall onto the arc-shaped slide 7. During the descent of the inner ring of the bearing, the pressure rod 25 plays a guiding role. The electromagnet 22 is energized to adsorb the inner circle of the bearing in the second position. The motor 3 drives the arm 4 to swing inward, so that the two push blocks 5 push the inner circle of the bearing along the arc-shaped slide 7 and press it against the two positioning blocks 2, thereby fixing the inner circle of the bearing. At this time, the main shaft of the grinder drives the grinding head to process the inner circle of the bearing. After the processing is completed, the two electromagnets 1 6 are energized to adsorb the inner circle of the bearing, and the motor 3 is reversed to rotate the arm 4 outward, so that the two push blocks 5 pull the inner circle of the bearing outward along the arc-shaped slide 7 through the two electromagnets 1 6, thereby realizing the discharge of the inner circle of the bearing, improving work efficiency, and avoiding danger when retrieving materials.

[0023] Example 2

[0024] like Figures 1 to 5As shown, on the basis of Example 1, it also includes a shaft rod 10, an arc baffle 11 and a torsion spring 12. A notch is set at the top of the outer arc of the arc slide 7, and the notch is used for the inner circle of the bearing to slide out. The shaft rod 10 is installed at one end of the notch away from the positioning block 2. The end of the arc baffle 11 is rotatably connected to the shaft rod 10, one end of the torsion spring 12 is connected to the arc baffle 11, and the other end of the torsion spring 12 is connected to the shaft rod 10; it also includes a vertical rod 13, a roller 14 and a spring 15. The upper end surface of the arc baffle 11 is an inclined surface, and the end of the arc baffle 11 away from the positioning block 2 is lower than the end close to the positioning block 2. The vertical rod 13 is vertically installed on the end of the arm rod 4 facing the arc baffle 11, and the roller 14 is slidably installed on the vertical rod 13. One end of the spring 15 is connected to the roller 14, and the other end of the spring 15 is connected to the arm rod 4. The elastic force of -15 pulls the roller 14 downward, and the lowest position of the roller 14 is higher than the lowest end of the arc baffle 11 and lower than the highest end of the arc baffle 11. The wheel surface of the roller 14 rolls and supports the inner wall of the arc baffle 11 to open the arc baffle 11; it also includes a lever 16, a push roller 17, an arc rack 18, a gear shaft 19 and a blocking plate 20. The middle part of the lever 16 is rotatably mounted on the arm 4 through an axis rod, and an elastic component is arranged between the lever 16 and the arm 4. A push roller 17 is arranged on the end of the lever 16 facing the push block 5, the arc rack 18 is mounted on the arm 4, and the gear shaft 19 is rotatably mounted on the base plate 1. When the arc baffle 11 is opened by the roller 14, the arc rack 18 engages with the gear shaft 19, and the blocking plate 20 is mounted on the gear shaft 19. When the blocking plate 20 is driven horizontally by the gear shaft 19, it blocks the end of the lever 16.

[0025] The elastic force of the torsion spring 12 causes the arc baffle 11 to block the notch of the arc chute 7. When the arm 4 swings toward the positioning block 2 to push the inner circle of the bearing to load the material, the lower end face of the roller 14 is supported by the upper end face of the arc baffle 11 and gradually rises along the vertical rod 13 during the movement to stretch the spring 15. When the roller 14 is separated from the arc baffle 11, the spring 15 contracts and causes the roller 14 to drop and reset. Therefore, during the loading process, the arc baffle 11 blocks the notch of the arc chute 7 to prevent the inner circle of the bearing from falling off. When the inner circle of the bearing is processed, when the arm 4 swings outward to pull the inner circle of the bearing to load the material, the wheel surface of the roller 14 is outward. The arc baffle 11 is rolled and squeezed, so that the arc baffle 11 automatically opens the gap of the arc chute 7 around the shaft 10, and the two electromagnets 16 are de-energized to release the inner circle of the bearing, and the arc rack 18 begins to engage with the gear shaft 19, so that the gear shaft 19 drives the blocking plate 20 to rotate, so that the blocking plate 20 rotates from the longitudinal position to the transverse position, so that the blocking plate 20 blocks the end of the shift rod 16 away from the push roller 17, so that the other end of the shift rod 16 drives the push roller 17 to approach the two push blocks 5, so that the push roller 17 automatically discharges the inner circle of the bearing between the two push blocks 5 from the gap of the opened arc chute 7, thereby realizing automatic unloading.

[0026] like Figures 1 to 6 As shown, the utility model is a bearing fixing device for processing the inner circle of a bearing. When it is working, it first stacks multiple inner circles of bearings and loads them between the supporting column 21 and the pressure rod 25, and enables the electromagnet 22 to adsorb the inner circle of the lowest bearing. The motor 3 drives the arm 4 to rotate to the side of the supporting column 21 away from the positioning block 2. The electromagnet 22 is powered off so that the inner circle of the lowest bearing falls onto the arc-shaped slide 7. During the descending process of the inner ring of the bearing, the pressure rod 25 plays a guiding role. The electromagnet 22 is powered on to adsorb the inner circle of the bearing in the second position. Then the arm 4 rotates and pushes the inner circle of the lowest bearing to be pressed against the two positioning blocks 2 through the two pushing blocks 5 to achieve the fixation of the inner circle of the bearing. Then the main shaft of the grinder drives the grinding head to process the inner circle of the bearing. After the processing is completed, the two electromagnetic Iron 16 is energized to adsorb the inner circle of the bearing, and the motor 3 is reversed to rotate the arm 4 outward, so that the two push blocks 5 pull the inner circle of the bearing outward along the arc chute 7 through the two electromagnets 16. At the same time, the wheel surface of the roller 14 rolls outward to squeeze the arc baffle 11, so that the arc baffle 11 automatically opens the gap of the arc chute 7 around the shaft 10. Finally, the arc rack 18 begins to engage with the gear shaft 19, so that the gear shaft 19 drives the baffle plate 20 to rotate, so that the baffle plate 20 rotates from longitudinal to transverse, so that the baffle plate 20 blocks the end of the shift rod 16 away from the push roller 17, so that the other end of the shift rod 16 drives the push roller 17 to approach the two push blocks 5, so that the push roller 17 automatically discharges the inner circle of the bearing between the two push blocks 5 from the gap of the opened arc chute 7, and the automatic unloading is completed.
