Description

Technical Field

[0001] The utility model relates to the technical field of bearing fixtures, in particular to a positioning structure for bearing processing. Background Art

[0002] Bearings are an important component in mechanical equipment, mainly used to support mechanical rotating bodies and reduce the friction coefficient during their movement.

[0003] Currently, the production of bearings requires grinding (generally grinding the inner ring or outer ring of the bearing). During the grinding process, the bearing needs to be fixed and positioned to ensure the stability of the grinding. Today's positioning structure only has the function of fixing the bearing. During the bearing grinding process, it is usually necessary to move the bearing to make the bearing grinding process smoother. However, the current positioning structure cannot make the bearing movable after fixing it. Therefore, the existing positioning structure is not suitable for today's bearing grinding process.

[0004] In summary, improvements need to be made. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a fixture for bearing processing, aiming to solve the problems arising from the above-mentioned background technology.

[0006] The technical solution of the present utility model is implemented as follows: a positioning structure for bearing processing, including a main board that can be installed on a machine tool, characterized in that at least three positioning wheels are rotatably connected to the main board, and a driving structure that can drive the positioning wheels to rotate synchronously is provided at the bottom of the main board.

[0007] Preferably, the driving structure includes:

[0008] A driving wheel connected to the positioning wheel through a transmission shaft;

[0009] Synchronous transmission belt, connecting between the driving wheels;

[0010] Among them, any driving wheel can be controlled by the motor to rotate clockwise or counterclockwise.

[0011] Preferably, the positioning wheel includes:

[0012] a wheel body, rotatably disposed on the main board;

[0013] The guide body is coaxially mounted on the wheel body;

[0014] Wherein, the guide body is in the shape of a truncated cone.

[0015] Preferably, the guide body is rotatably connected to the wheel body via a first rotating shaft and is spaced apart from the wheel body, and a limiting structure is further provided between the wheel body and the guide body, wherein the limiting structure includes:

[0016] A limiting piece is rotatably connected to the wheel body via a second rotating shaft;

[0017] A driven gear is mounted on the second rotating shaft;

[0018] A driving gear is provided on the first rotating shaft and meshes with the driven gear;

[0019] The guide body and the first rotating shaft can slide in the axial direction relative to each other.

[0020] Preferably, the matching surfaces of the guide body and the first rotating shaft are provided with mutually matching limiting ribs and limiting sliding grooves.

[0021] Preferably, the guide body is formed with an axial cavity which cooperates with the first rotating shaft and allows the first rotating shaft to slide, and the limiting sliding groove is provided in the axial cavity;

[0023] Preferably, a handle is provided at one end of the guide body away from the wheel body.

[0024] The utility model has at least the following beneficial effects:

[0025] 1.

[0037] Example 1

[0038] like Figure 1-3 As shown, the utility model discloses a positioning structure for bearing processing, including a main board 10 that can be installed on a machine tool, four positioning wheels 20 are rotatably connected to the main board 10, and a driving structure that can drive each positioning wheel 20 to rotate synchronously is provided at the bottom of the main board 10.

[0039] In this embodiment, the driving structure includes:

[0040] The driving wheel 30 is connected to the positioning wheel 20 via a transmission shaft 31;

[0041] Synchronous transmission belt 31a, connected between the driving wheels 30;

[0042] Any driving wheel 30 can be controlled by the motor 32 to rotate clockwise or counterclockwise.

[0043] In this embodiment, the positioning wheel includes:

[0044] The wheel body 200 is rotatably mounted on the main board 10 and connected to the transmission shaft 31;

[0045] The guide body 201 is coaxially mounted on the wheel body 200;

[0046] The guide body 201 is in the shape of a truncated cone.

[0047] In this embodiment, a bearing support plate 40 is rotatably connected to the main board 10 .

[0048] refer to Figure 1-3 When this embodiment is in use, the main board is installed on the machine tool, and when grinding the bearing, the bearing components (such as the bearing outer ring) are placed on the bearing support plate, and the outer wall of the bearing outer ring is made to contact with each positioning wheel. When grinding the inner wall of the bearing outer ring, the grinding tool is made to contact with the inner wall of the bearing outer ring. The motor controls the rotation of the positioning wheel to make the bearing rotate, thereby facilitating the grinding of the bearing outer ring.

[0049] The guide body provided in this embodiment can guide the bearing to move toward the bearing support plate when the bearing is placed, thereby facilitating loading.

[0050] Example 2 is different from Example 1 in that:

[0051] like Figure 4-7 As shown, in this embodiment, the guide body 201 is rotatably connected to the wheel body 200 via the first rotating shaft 50 and is spaced apart from the wheel body 200. A limiting structure is further provided between the wheel body 200 and the guide body 201, wherein the limiting structure includes:

[0052] The limiting piece 51 is rotatably connected to the wheel body 200 via the second rotating shaft 52;

[0053] The driven gear 53 is mounted on the second rotating shaft 52;

[0054] The driving gear 54 is disposed on the first rotating shaft 50 and meshes with the driven gear;

[0055] The guide body 201 and the first rotating shaft 50 can slide relative to each other in the axial direction.

[0056] In this embodiment, the matching surfaces of the guide body 201 and the first rotating shaft 50 are provided with mutually adapted limiting ribs 61 and limiting sliding grooves 62 .

[0057] In this embodiment, the guide body 201 is formed with a shaft cavity 70 that cooperates with the first rotating shaft 50 and allows the first rotating shaft 50 to slide. The shaft cavity 70 is provided with the limiting sliding groove;

[0058] A limit spring 71 is connected between the first rotating shaft 50 and the shaft cavity 70 .

[0060] refer to Figure 4-7 In order to improve the stability of the fixed bearing, this embodiment provides a limiting structure on the wheel body. When in use, the handle is used to pull the guide body away from the wheel body, and the guide body is separated from the driven gear, damaging the rotating guide body and driving the driving gear to rotate through the first rotating shaft, so that the driven gear drives the limiting plate to rotate, so that the limiting plate moves out to limit the outer ring of the bearing. After the adjustment is completed, the handle is released, and the guide body is driven to reset by the limiting spring and the guide body is against the driven gear, thereby preventing the driven gear from rotating and completing the limiting of the outer ring of the bearing.

[0061] After the bearing is polished, the handle is used again to drive the guide body away from the driven gear and drive the guide body to rotate, so that the limit plate rotates around the second rotation axis and retracts into the gap formed between the guide body and the wheel body, so that the outer ring of the bearing can be removed.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
