Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] In the description of the utility model, it is still necessary to point out that, unless explicitly defined and limited, the terms "set", "set", "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model should be understood according to the specific circumstances.

[0027] As Figs. 1-3The utility model provides a kind of universal bearing puller frock, the universal bearing puller frock includes base, clamping plate, flange end, plug-in interface, weight reduction groove, bolt, transition surface;Base 1 includes clamping plate 11, flange end 12, plug-in interface 13 and weight reduction groove 14, flange end 12 is fixedly arranged in the both ends of clamping plate 11, and flange end 12 is connected into an organic whole with clamping plate 11, the cross section of flange end 12 is rectangle, the rim of the both ends of clamping plate 11 is the straight line along mouth of flat, clamping plate 11 provides the support of overall structure, ensure the stability of device.Each flange end 12 is provided with plug-in interface 13 in the protruding end, every two adjacent flange end 12, there is a bolt 2 and is arranged in the plug-in interface 13 of two flange end 12.Weight reduction groove 14 is arranged in one side of clamping plate 11, the position of weight reduction groove 14 covers the symmetry axis of clamping plate 11, and the setting number of weight reduction groove 14 corresponds to clamping plate 11 one by one;The design of weight reduction groove 14 not only reduces the overall weight of frock, but also helps to improve the operation convenience and cost-effectiveness of frock.Base 1 is provided with three, and the outer diameter of three bases 1 is on a circular contour line.Base 1 is one of the core components of entire universal bearing puller frock, and its main function is to provide stable support and clamping force.

[0028] Weight reduction groove 14 is arranged in one side of clamping plate 11 and extends along the symmetry axis of clamping plate 11, and its design intention is to reduce the weight of frock and increase the operability of frock.Meanwhile, weight reduction groove 14 also plays the role of aesthetics and structural optimization, reduces the use of materials, thereby reducing manufacturing cost, and the area where weight reduction groove 14 is located adopts light material, so as to reduce unnecessary weight and improve the flexibility of operation.

[0029] The clamping cutout 4 of three bases 1 is on a circular outer contour line, and the arc fluctuation of transition surface 3 is higher than clamping cutout 4.Through these designs, multiple bases 1 can be connected by bolt 2 to form stronger clamping force, adapt to the demand of different bearing models.The outer contour of base 1 is circular, and the bases 1 form a symmetrical design, and when multiple bases 1 are combined together, the distribution of clamping force is more uniform, preventing damage to bearings when being pulled out due to uneven force.The design of arc fluctuation of transition surface 3 helps to better adapt to different bearing shapes, ensuring that bearings can stably bear the force when being pulled out by puller.The outer surface of base 1 is coated with protective paint, which can effectively prevent rust and wear and tear, and increase the service life of frock.

[0030] In order to adapt to different sizes of bearings, the bolt 2 is designed to pass through the plug-in interface 13, and the screw rod of the bolt 2 is rotationally connected with the inner wall of the plug-in interface 13. The combination of the bolt 2 and the plug-in interface 13 in the design allows adjustment according to different bearing sizes. By rotating the bolt 2, the spacing between each base 1 can be accurately controlled, ensuring that the tool can adapt to shafts of various diameters and is less likely to damage the bearings due to improper tool size. The bolt should be made of high-strength alloy steel to ensure that it does not loosen easily during long-term operation and can withstand frequent adjustments without deformation or breakage.

[0031] The transition surface 3 is arc-shaped and is arranged on one side of the outer diameter side of the clamping plate 11. The arc-shaped gradual design of the transition surface 3 can help evenly distribute the pulling force to the entire contact surface, avoiding stress concentration. This helps prevent uneven stress on the bearing and reduces the risk of bearing damage, especially when the bearing surface is relatively fragile. The transition surface 3 is designed in a streamlined manner, allowing the tool to adapt to bearings of different shapes and sizes. During disassembly, the transition surface 3 can effectively contact the bearing outer ring, ensuring that there are no sharp angles or uneven force transmission, protecting the bearing from scratches or damage. The design of the transition surface 3 helps the tool make precise contact with the bearing, reducing asymmetry in the tool and bearing contact, ensuring accurate alignment during each operation and improving assembly and disassembly accuracy.

[0032] The clamping cutout 4 is arranged on the other side of the clamping plate 11. It helps to fix and control the bearing during operation. The design of the cutout can adjust the depth and range of clamping according to the different diameters of the bearing, ensuring that the clamping force is strong enough to prevent the bearing from loosening or sliding during disassembly. Especially when a large torque is required, the clamping cutout 4 can ensure that the bearing is securely fixed to the tool. The clamping cutout 4 is usually designed precisely to avoid direct contact between the sharp edges of the contact surface and the bearing surface. By reasonably designing the shape and position of the cutout, it ensures that the clamping part only exerts pressure on the bearing outer ring, without affecting the bearing inner ring or other sensitive parts. This reduces the risk of bearing rupture or deformation caused by improper clamping

[0033] It should be noted that the universal bearing puller tool designed by the utility model can be adjusted by adjusting the bolt 2 to adapt to different bearings. The nut of the bolt 2 can be rotated axially to pull apart or pull together the spacing between each base 1, thereby adjusting the clamping plate 11 to adapt to the diameter of the different shafts it is fitted to. The flange on the base 1 can be directly placed into the inner diameter of the bearing when the bearing has a large inner diameter, and the force is applied to the bearing inner ring to ensure that the bearing is not damaged when pulled out by the puller.

[0034] Although the embodiments of the present application have been shown and described, it is to be understood that the application is not limited to the above-mentioned embodiments and various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
