Description

Technical Field

[0001] This utility model belongs to the field of bearing processing technology, and specifically relates to a bearing ring polishing device for bearing production. Background Technology

[0002] The main purpose of polishing bearing races is to improve their surface smoothness and brightness, and to remove surface defects and hardened layers. Through polishing, the bearing surface becomes smoother, reducing friction and improving the bearing's rotational accuracy and service life. Furthermore, polishing removes burrs and impurities from the bearing surface, ensuring the bearing's stability during operation.

[0003] When polishing bearing rings, due to the different clamping methods, only the inner or outer diameter of the bearing ring can be ground. When clamping the outer diameter of the bearing ring, only the inner diameter can be polished, and when clamping the inner diameter of the bearing ring, only the outer diameter can be ground. It is impossible to simultaneously satisfy the polishing of both the inner and outer diameters of the bearing ring in one clamping, which makes the polishing process of bearing rings inconvenient. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a bearing ring polishing device for bearing production, which can simultaneously perform polishing processing on the inner and outer diameters of the bearing ring in one clamping, thereby making the polishing process of the bearing ring more convenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bearing ring polishing device for bearing production includes a base, an upright plate fixed on the upper surface of the base and a first guide rail horizontally fixed on the base on the right side of the upright plate, two support rollers supporting the bearing ring are installed on the right side of the upright plate, and a rotary motor for driving one of the support rollers to rotate is fixed on the left side of the upright plate. An upward guide opening is provided on the upper side of the upright plate, and a movable block that can move up and down is fitted inside the guide opening. A fixed plate is fixed at the upper end of the upright plate, and an electric lifting rod for driving the movable block to move up and down is fixed on the upper side of the fixed plate. A pressure roller for pressing the upper side of the bearing ring is rotatably installed on the right side of the movable block.

[0007] A movable plate is mounted on the first guide rail, and an electric telescopic rod that drives the movable plate to move left and right is fixed to the right end of the first guide rail. A movable seat is mounted on the upper side of the movable plate. A polishing head is installed on the left side of the movable seat, and a grinding motor that drives the polishing head to rotate is fixed to the right side of the movable seat. A drive mechanism that drives the movable seat to move back and forth is fixed to the upper side of the movable plate.

[0008] Furthermore, the movable block has slots on both the front and rear sides that engage with the side walls of the guide opening, and a connecting plate is fixed on the left side of the movable block.

[0009] Furthermore, a stepped shaft is fixed to the left end of the support roller, and a connecting shaft connected to the output shaft of the rotating motor is fixed to the left end of the stepped shaft.

[0010] Furthermore, the drive mechanism includes a support plate fixed to the upper side of the movable plate, a lead screw threaded through the movable seat is installed on the rear side of the support plate, and a drive motor for driving the lead screw to rotate is fixed on the front side of the support plate.

[0011] Furthermore, a second guide rail is fixed on the upper side of the movable plate to movably engage the movable seat, and a guide slot is provided on the lower side of the movable plate to engage with the first guide rail.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When the electric telescopic rod drives the movable plate to move to the left, the polishing head is aligned with the side of the bearing ring. The drive mechanism drives the movable seat to move the polishing head forward or backward to contact the inner or outer diameter of the bearing ring for polishing. At the same time, the rotating motor drives the support roller to rotate, thereby driving the bearing ring to rotate to better cooperate with the polishing head for polishing. This allows for polishing of both the inner and outer diameters of the bearing ring in one clamping, making the polishing process of the bearing ring more convenient.

[0014] 2. When clamping the bearing ring, place it on two support rollers. At this time, the electric lifting rod drives the movable block to lower the pressure roller to press the upper side of the bearing ring, thereby completing the quick clamping of the bearing ring.

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1 As shown, a bearing ring polishing device for bearing production includes a base 1. A vertical plate 4 and a first guide rail 15 located on the right side of the vertical plate 4 and horizontally fixed on the base 1 are fixed on the upper surface of the base 1. Two support rollers 3 for supporting the bearing ring are installed on the right side of the vertical plate 4. A rotary motor 2 for driving one of the support rollers 3 to rotate is fixed on the left side of the vertical plate 4. An upward guide opening 8 is opened on the upper side of the vertical plate 4. A movable block 6 that can move up and down is clamped inside the guide opening 8. A fixed plate 5 is fixed at the upper end of the vertical plate 4. An electric lifting rod 7 for driving the movable block 6 to move up and down is fixed on the upper side of the fixed plate 5. A pressure roller 9 for pressing the upper side of the bearing ring is rotatably installed on the right side of the movable block 6. When clamping the bearing ring, it is placed on the two support rollers 3. At this time, the electric lifting rod 7 drives the movable block 6 to drive the pressure roller 9 to descend and press the upper side of the bearing ring, thereby completing the rapid clamping of the bearing ring.

[0024] like Figure 1As shown, a movable plate 16 is mounted on the first guide rail 15, and an electric telescopic rod 14 for driving the movable plate 16 to move left and right is fixed to the right end of the first guide rail 15. A movable seat 11 is mounted on the upper side of the movable plate 16. A polishing head 10 is installed on the left side of the movable seat 11, and a grinding motor 12 for driving the polishing head 10 to rotate is fixed to the right side of the movable seat 11. A drive mechanism 13 for driving the movable seat 11 to move back and forth is fixed to the upper side of the movable plate 16. The electric telescopic rod 14 drives the movable plate 16 to move to the left so that the polishing head 10 is aligned with the side of the bearing ring. The drive mechanism 13 drives the movable seat 11 to move the polishing head 10 forward or backward to contact the inner or outer diameter of the bearing ring for polishing. At the same time, the rotating motor 2 drives the support roller 3 to rotate, thereby driving the bearing ring to rotate to better cooperate with the polishing head 10 for polishing. This allows for the simultaneous polishing of the inner and outer diameters of the bearing ring in one clamping, making the polishing process of the bearing ring more convenient.

[0025] like Figure 2 As shown, the movable block 6 has slots 62 on both the front and rear sides that are engaged with the side walls of the guide opening 8. The movable block 6 is engaged in the guide opening 8 by means of the slots 62. A connecting plate 61 is fixed on the left side of the movable block 6. The connecting plate 61 is used to connect with the electric lifting rod 7.

[0026] like Figure 3 As shown, a stepped shaft 32 is fixed to the left end of the support roller 3. The stepped shaft 32 uses the step between itself and the support roller 3 to limit the placement of the bearing ring.

[0027] The left end of the stepped shaft 32 is fixed with a connecting shaft 31 that is connected to the output shaft of the rotating motor 2. The stepped shaft 32 is driven to rotate by connecting the rotating motor 2 through the connecting shaft 31.

[0028] like Figure 4 As shown, the drive mechanism 13 includes a support plate 132 fixed on the upper side of the movable plate 16. A lead screw 133 threaded through the movable seat 11 is installed on the rear side of the support plate 132, and a drive motor 131 for driving the lead screw 133 to rotate is fixed on the front side of the support plate 132. The drive motor 131 drives the lead screw 133 to rotate, and the rotating lead screw 133 drives the movable seat 11 to adjust its movement in the front and rear directions.

[0029] like Figure 5 As shown, a second guide rail 161 is fixed on the upper side of the movable plate 16 to movably engage the movable seat 11. The movable plate 16 uses the second guide rail 161 to guide the movable seat 11 in the front-back direction.

[0030] The lower side of the movable plate 16 is provided with a guide slot 162 that is engaged with the first guide rail 15. The movable plate 16 is guided to move on the first guide rail 15 by means of the guide slot 162.

[0031] The working principle of this utility model is as follows: When polishing the bearing ring, the bearing ring is placed on two support rollers 3. At this time, the electric lifting rod 7 drives the movable block 6 to drive the pressure roller 9 to descend and press the upper side of the bearing ring. Then, the rotating motor 2 drives the support roller 3 to rotate, thereby driving the bearing ring to rotate. At this time, the electric telescopic rod 14 drives the movable plate 16 to move to the left, so that the polishing head 10 extends into the inner side of the bearing ring and aligns with the inner side of the bearing ring. The drive motor 131 drives the lead screw 133 to rotate. The rotating lead screw 133 drives the movable seat 11 to move backward, thereby driving the polishing head 10 to move backward and contact the inner diameter of the bearing ring for polishing.

[0032] Then, control the movable plate 16 to move to the right so that the polishing head 10 is away from the bearing ring, and control the movable seat 11 to drive the polishing head 10 to move backward so that it moves to the outside of the bearing ring. Then, control the movable plate 16 to move to the left again so that the polishing head 10 is aligned with the outer side of the bearing ring. At this time, control the movable seat 11 to move forward so that the polishing head 10 moves forward to contact the outer diameter of the bearing ring for polishing.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
