Description

Technical Field

[0001] The utility model belongs to the technical field of bearing shape preservation, and in particular relates to a bearing processing shape preservation tool. Background Art

[0002] Bearing is an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

[0003] Traditional bearings require cutting of the bearing rings on the bearings during processing. However, during the clamping process, the high temperature and high pressure environment during cutting and grinding, as well as the clamping pressure of the clamping parts, can easily lead to an imbalance in the pressure inside and outside the bearing rings, until the bearing rings are squeezed inward, collapsed and damaged, which can easily cause product processing failure. Therefore, a bearing processing conformal tooling is needed to solve the above problem. Utility Model Content

[0004] The utility model aims to provide a bearing processing conformal tooling to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bearing processing conformal tooling, comprising a base, a vertical block fixedly connected to the base, a toothed ring rotatably connected to the front of the vertical block, a plurality of toothed columns meshed inside the toothed ring, a plurality of toothed columns are rotatably connected to the front of the vertical block, a plurality of racks are slidably connected to the front of the vertical block through a T-shaped slide bar, a plurality of racks are respectively meshed with the upper parts of a plurality of toothed columns, a plurality of racks are fixedly connected to the adjacent ends of a plurality of racks, a polygonal protrusion is rotatably connected to the front of the vertical block, a plurality of pressing protrusions are rotatably connected to the front of the vertical block, and the pressing protrusions are magnetically attracted to the surface of the polygonal protrusion through a magnetic attraction surface. The front side of the vertical block is rotatably connected with a gear, and the gear ring is meshed with the gear through external teeth. The gear is fixedly connected to the first bevel gear at the rotation point on the back side of the vertical block. The back side of the vertical block is fixedly connected with a fixed block. The lower surface of the fixed block is fixedly connected with a motor. The output shaft of the motor is fixedly connected to the first bevel gear. The polygonal protrusion is fixedly connected with a worm gear at the rotation point on the back side of the vertical block. Two connecting blocks are fixedly connected to the back side of the vertical block. The adjacent sides of the two connecting blocks are rotatably connected with a worm screw together. The worm screw and the worm gear are meshed with each other. The rotation point of one end of the worm screw is fixedly connected with a second bevel gear. The first bevel gear and the second bevel gear are meshed with each other.

[0006] By setting the above structure, when the motor is started, the motor will drive multiple clamping blocks to clamp the outside of the bearing ring through a series of transmissions, and at the same time as the motor is started, it will also drive the polygonal protrusions to rotate through a series of transmissions. When the polygonal protrusions rotate, the protruding parts of the multiple pressing protrusions will rotate outward through the rotation of their convex angles, and then the multiple pressing protrusions will flip out and protrude to press against the inner surface of the bearing ring. In this way, the inside and outside of the bearing ring can be firmly clamped and positioned, and the bearing ring will not be easily squeezed, collapsed and damaged during the later processing because its inner surface is supported, which helps to ensure the probability of successful product processing.

[0007] As a preferred implementation, the plurality of racks are all located in front of the gear column.

[0008] As a preferred implementation manner, the polygonal protrusion is located at the center of the plurality of pressing protrusions.

[0009] As a preferred implementation, the diameter of the first bevel gear is greater than the diameter of the second bevel gear.

[0010] As a preferred implementation, the diameter of the gear is smaller than the diameter of the gear ring.

[0011] As a preferred implementation, the outer surface of the pressing protrusion is an arc-shaped surface.

[0012] By setting the diameter of the first bevel gear to be larger than that of the second bevel gear, and the diameter of the gear to be smaller than the gear ring, the clamping of the clamping block and the pressing of the pressing protrusion can be kept synchronized by adjusting the reduction ratio between the gears, which helps the bearing ring to achieve a stable clamping effect.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model provides a pressing protrusion. When the motor is started, the motor drives the multiple clamping blocks to clamp the outside of the bearing ring through a series of transmissions. When the motor is started, the multi-angle protrusion is also driven to rotate through a series of transmissions. When the multi-angle protrusion rotates, the protruding parts of the multiple pressing protrusions are pressed to rotate outwards through the rotation of the convex angles of the multi-angle protrusions. Then, the external parts of the multiple pressing protrusions are turned over and protruded to press against the inner surface of the bearing ring. In this way, the inside and outside of the bearing ring can be firmly clamped and positioned. In the later processing, the bearing ring will not be easily squeezed, collapsed and damaged due to the support of its inner surface, which helps to ensure the probability of successful product processing.

[0015] The utility model sets the diameter of the first bevel gear to be larger than that of the second bevel gear, and the diameter of the gear is smaller than that of the gear ring. By adjusting the reduction ratio between the gears, the clamping of the clamping block and the pressing of the pressing protrusion can be kept synchronized, which helps the bearing ring to achieve a stable clamping effect.
