Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing technology, specifically to a bearing connecting ring extrusion tool. Background Technology

[0002] The primary function of bearings is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Without bearings, shafts in machines would not rotate smoothly or would wear out rapidly. Bearing production is a systematic engineering process that transforms raw materials (mainly steel) into high-precision components. This involves more than just simple cutting; it also includes complex material handling and precision machining.

[0003] In the bearing industry, bearing connections are mostly made using connecting rings, which are then processed using rollers. However, this method is suitable for bearings with simple structures and large inner diameters. If the bearing inner diameter is small and the connecting ring shape is complex, the rolling method cannot achieve the connection, so improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a bearing connecting ring extrusion tool to solve the problem that the rolling method mentioned in the background art is not suitable for the installation of bearings with small inner diameter and negative pressure on the connecting ring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing connecting ring extrusion fixture, including a hydraulic frame, a fixing clamp is provided on the inner side of the hydraulic frame, a bearing body is clamped on the inner side of the fixing clamp, a mold assembly is provided inside the bearing body, a first hydraulic cylinder and a third hydraulic cylinder are respectively installed on the top and bottom of the hydraulic frame, and a first pressure plate and a second pressure plate are respectively connected to one end of the first hydraulic cylinder and the third hydraulic cylinder.

[0006] The mold assembly is located between the first pressure plate and the second pressure plate. The mold assembly includes a lower mold inserted into the bearing body, a rubber block on the top of the lower mold, an upper mold on the top of the rubber block, and a connecting ring sleeved on the outer wall of the rubber block.

[0007] Preferably, both the upper and lower molds are made of metal, and both the upper and lower molds are slidably connected to the hydraulic structure.

[0008] Preferably, a lower mold is placed on the top of the second pressure plate, and an upper mold is provided at the bottom of the first pressure plate.

[0009] Preferably, a second hydraulic cylinder is fixedly connected to one side of the hydraulic frame, and the second hydraulic cylinder is symmetrically distributed about the bisector of the hydraulic frame.

[0010] Preferably, one end of the second hydraulic cylinder is fixedly connected to the fixing clamp, and a rubber protective pad is provided on the inner side of the fixing clamp.

[0011] Preferably, both the fixing clamp and the rubber protective pad are arc-shaped structures, with the inner side of the rubber protective pad adhering to the outer wall of the bearing body.

[0012] Preferably, the inner ring of the bearing housing has an arc groove, and the arc groove is distributed in three equally spaced rings around the inner ring of the bearing housing.

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

[0014] (1) This device improves installation efficiency by using the extrusion method. The installation is also simpler and more time-saving, thereby improving overall production efficiency while improving installation safety.

[0015] (2) This device sets up a mold assembly. The upper mold, lower mold and rubber block of the mold assembly can be inserted into the inner ring of the bearing body. By applying pressure and deformation, the rubber block pushes the connecting ring on the outer wall to deform and be inserted into the inner ring of the bearing body, thus achieving a fast and stable connection and improving installation efficiency.

[0016] (3) This device can match the shape of the connecting ring after it is squeezed by opening an arc groove in the inner ring of the bearing body, thereby improving the firmness of the connection between the connecting ring and the bearing body. Attached Figure Description

One end of the pressure cylinder 7 is fixedly connected to the fixed clamp 6. A rubber protective pad 8 is provided inside the fixed clamp 6. The second hydraulic cylinder 7 is controlled by a PLC to ensure synchronous movement. Simultaneously, the second hydraulic cylinder 7 can automatically push the fixed clamp 6 to clamp and fix the bearing body 2, ensuring the stability of the bearing body 2 during the extrusion process. The bearing body 2 is clamped inside the fixed clamp 6. A mold assembly 3 is provided inside the bearing body 2. A first hydraulic cylinder 4 and a third hydraulic cylinder 11 are respectively installed at the top and bottom of the hydraulic frame 9. One end of the first hydraulic cylinder 4 and the third hydraulic cylinder 11 are respectively connected to a first pressure plate 5 and a second pressure plate 10. A lower mold 32 is placed on the top of the second pressure plate 10, and an upper mold 31 is provided at the bottom of the first pressure plate 5. The second pressure plate 10 and the first pressure plate 5 can respectively apply pressure to the lower mold 32 and the upper mold 31. To ensure consistent pressure input at both ends, the accuracy of applying pressure to the upper and lower ends of the connecting ring 1 is improved, ensuring a stable connection between the connecting ring 1 and the inner ring of the bearing body 2. The first hydraulic cylinder 4 and the third hydraulic cylinder 11 are controlled by a PLC to ensure synchronous movement. The mold assembly 3 is located between the first pressure plate 5 and the second pressure plate 10. The mold assembly 3 includes a lower mold 32 inserted inside the bearing body 2.

Subsequently, the mold assembly 3 is inserted into the inner ring of the bearing body 2. At this time, the lower mold 32 is located on top of the second pressure plate 10. After adjusting the position of the mold assembly 3, the first hydraulic cylinder 4 and the third hydraulic cylinder 11 are started. The first hydraulic cylinder 4 and the third hydraulic cylinder 11 simultaneously push the first pressure plate 5 and the second pressure plate 10 to press the upper mold 31 and the lower mold 32 respectively, causing the middle rubber block 33 to deform. During the deformation of the rubber block 33, the connecting ring 1 is pushed to deform and move closer to the inner ring of the bearing body 2 until the connecting ring 1 is completely connected to the inner ring of the bearing body 2. Finally, the first pressure plate 5 and the second pressure plate 10 are reset to remove the bearing body 2.
