Description

Technical Field

[0001] This utility model relates to the field of bearing processing and assembly technology, and in particular to a tooling for a mandrel assembly component of a combined bearing. Background Technology

[0002] In the field of bearing processing and assembly technology, with the continuous development of industry, the application range of bearings is becoming increasingly wide, and their performance and quality play a crucial role in the normal operation of various mechanical equipment. As an indispensable component in mechanical equipment, the precision and efficiency of bearing processing and assembly directly affect the performance and reliability of the entire equipment. High-quality bearings can effectively reduce equipment vibration and noise, improve the operational stability and service life of the equipment, thereby bringing higher efficiency and lower costs to industrial production. During the operation of various mechanical equipment, bearings need to withstand enormous pressure and friction; therefore, the quality of their processing and assembly is directly related to the safety and reliability of the equipment.

[0003] During the machining and assembly of bearings, when it is necessary to install accessories such as magnetic rings on a bearing mandrel that has already been assembled with an outer ring, oil seal, and cage, the conventional approach is to directly install them. One method is to forcibly insert the magnetic ring or other accessories into the mandrel. This method is simple to operate, but it is difficult to precisely control the installation position and force during the installation process.

[0004] Existing technologies for adding accessories such as magnetic rings to bearing spindles that have already been assembled with outer rings, oil seals, and cages have significant drawbacks. Because it is difficult to avoid stress on the outer ring during installation, relative displacement between the spindle and the outer ring can easily occur, leading to damage to the cage, steel balls, and ultimately the bearing itself. Furthermore, existing installation methods are relatively cumbersome, not only affecting installation efficiency but also increasing the risk of bearing damage. Utility Model Content

[0024] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] This utility model discloses a tooling for a mandrel assembly component of a combined bearing, such as... Figure 1 As shown, the fixture includes a fixture body 1 and a pressing mechanism 5. The fixture body 1 and the pressing mechanism 5 work together. The pressing mechanism 5 is located on the top of the fixture body 1. The fixture body 1 provides space for the placement and operation of the magnetic ring 4 and the bearing 3. The pressing mechanism 5 is used to press down on the bearing 3 to assemble the magnetic ring 4 on the bearing 3 spindle. This fit avoids relative displacement between the spindle and the outer ring during installation, ensuring that the bearing 3 will not be damaged.

[0026] Specifically, the fixture body 1 includes two notches 2 at the top, an inner cavity 6, a slot 7, and a limiting block 9.

[0027] The notch 2 at the top of the fixture body 1 is relatively large, facilitating the insertion of the bearing 3 into the fixture from the top and increasing the operating space. The notch 2 is semi-circular in shape. A limiting block 9 is also provided at this notch 2. The limiting block 9 can be a block-shaped metal structure, fixed to the fixture body 1 by welding, bolting, or other methods. The function of the limiting block 9 is to limit the outer ring of the bearing 3, preventing lateral movement of the bearing 3 during insertion and pressing, ensuring accurate installation.

[0028] The notch 2 at the bottom of the top of the fixture body 1 is relatively small, mainly to facilitate the insertion of the magnetic ring 4. The shape of this notch 2 can also be designed according to the shape of the magnetic ring 4, such as circular or square. A slot 7 is provided at this notch 2. The slot 7 can be an annular groove, the size of which matches the magnetic ring 4, to fix the magnetic ring 4 and prevent the magnetic ring 4 from shaking inside the fixture body 1.

[0029] The fixture body 1 has an inner cavity 6. The top diameter of the inner cavity 6 matches the outer ring of the bearing 3, and its inner wall can be a smooth cylindrical surface. This allows the bearing 3 to be guided only by its outer ring without being clamped when it is inserted. The bottom diameter of the inner cavity 6 matches the outer diameter of the mandrel, allowing the mandrel to pass smoothly through the bottom of the inner cavity 6. The inner wall surface of the inner cavity 6 is provided with a wear-resistant layer. The wear-resistant layer can be a sprayed wear-resistant coating, such as ceramic coating or tungsten carbide coating, or it can be an inlaid wear-resistant bushing, such as a copper alloy bushing or a stainless steel bushing. The wear-resistant layer reduces the friction between the bearing 3 and the mandrel and the inner wall of the fixture body 1, extending the service life of the fixture body 1.

[0030] The combined structure of the fixture body 1 provides a stable placement and operating environment for the installation of the magnetic ring 4 and the bearing 3. The upper notch 2 and the limiting block 9 ensure the convenience and accuracy of inserting the bearing 3, while the lower notch 2 and the slot 7 facilitate the placement and fixation of the magnetic ring 4. The design of the inner cavity 6 ensures the guidance of the outer ring of the bearing 3 and the smooth passage of the mandrel, and the wear-resistant layer improves the durability of the fixture body 1.

[0031] Specifically, the pressing mechanism 5 includes a punch head 51 disposed on the top of the fixture body 1.

[0032] The stamping head 51 can be a cylindrical metal structure, and its bottom can be a flat surface or a curved surface that matches the shape of the outer ring of the bearing 3. The stamping head 51 achieves the pressing and resetting actions through hydraulic drive, electric drive, or other means. When the magnetic ring 4 needs to be installed, the stamping head 51 presses down to the specified depth, accurately fitting the magnetic ring 4 onto the mandrel of the bearing 3, and then the stamping head 51 resets, waiting for the next operation.

[0033] The stamping head 51 is connected to the top of the fixture body 1 through a guide rail, slider, and other structures to ensure that the stamping head 51 can accurately press down and return to its original position in the vertical direction. The stamping head 51 is connected to the drive device through a transmission rod, coupling, and other components to transmit the power of the drive device to the stamping head 51.

[0034] The cooperation between the stamping head 51 and the fixture body 1 enables the magnetic ring 4 to be accurately and stably installed on the bearing 3 mandrel. The downward pressing action of the stamping head 51 provides the pressure required for installation, while the fixture body 1 ensures the positional accuracy of the bearing 3 and the magnetic ring 4 during installation, avoiding relative displacement between the mandrel and the outer ring, thereby ensuring the quality of the bearing 3.

[0035] The implementation principle of this embodiment is as follows: The tooling in this embodiment, through the special design of the fixture body 1, including the top notch 2, inner cavity 6, slot 7, and limiting block 9, as well as the stamping head 51 of the pressing mechanism 5, enables the installation of a magnetic ring 4 on the bearing 3 spindle that has already been assembled with an outer ring, oil seal, and cage. During installation, the fixture body 1 only guides the outer ring of the bearing 3 without clamping it, avoiding relative displacement between the spindle and the outer ring due to force on the outer ring, thereby preventing damage to the cage, steel balls, etc., and ensuring the integrity of the bearing 3 body.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
