Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing installation technology, specifically to a tooling fixture for installing embedded bearings. Background Technology
[0002] Embedded bearings are a design that integrates bearings into the internal structure of equipment. Through a compact layout, they improve space utilization and mechanical stability. They are often used in high-precision, high-load scenarios, effectively reducing vibration, extending lifespan, and optimizing overall performance.
[0003] When installing embedded bearings, the inner ring typically mates with the shaft, while the outer ring mates with the bearing housing. Current common methods involve tapping the inner and outer rings separately with sleeves during installation. This requires attention to both mating areas, and the diameters of the inner and outer rings may increase after heating. This method is cumbersome because it requires repeated tapping of the inner and outer rings to fit the bearing into the mating area. It also necessitates changing the sleeves between the inner and outer rings, which can damage the bearing and results in low installation efficiency. Furthermore, the sleeves used for installation are not easily adjustable in diameter, and different sleeves are required for different bearing sizes, leading to poor applicability. Therefore, a tooling fixture for installing embedded bearings is proposed to solve these problems. Utility Model Content
[0004] The objective of this utility model can be achieved through the following technical solutions: A tooling fixture for mounting an embedded bearing includes an inner positioning mechanism, and an outer positioning mechanism is provided on the outside of the inner positioning mechanism. The inner positioning mechanism includes a mounting plate, with an inner guide rail fixedly connected to the outer wall of the front side of the mounting plate. The inner guide rails are arranged equidistantly around the axial direction of the mounting plate. A turntable is rotatably connected to the inner wall of the front side of the mounting plate. An extrusion groove is formed on the surface of the turntable near each inner guide rail. An inner ring pressure rod is slidably connected to the inner wall of each extrusion groove. The middle part of the inner ring pressure rod is slidably connected to the inner guide rail. Distance scales are set on the surface of each inner guide rail along its own length direction.
[0005] As a further embodiment of this utility model: an end plate is fixedly installed on the upper end of the front outer wall of the mounting plate, an arc-shaped groove is opened on the surface of the end plate, a sliding shaft is slidably connected to the inner wall of the arc-shaped groove, a second mounting hole is opened in the middle of the end face of the sliding shaft, a bolt is threadedly fastened to the inner wall of the second mounting hole, and the end face of the bolt is fitted with an anti-slip washer and abuts against the surface of the end plate, and the sliding shaft is fixed to the front edge of the turntable.
[0006] As a further embodiment of this utility model: a support pad is glued and fixed to the middle of the back of the mounting plate, a guide rod is connected through the inner side of the support pad, and the end of the guide rod is fixedly installed to the back of the mounting plate. A swing hammer is slidably sleeved on the outer wall of the guide rod, and a handle is fixedly connected to one side of the outer wall of the swing hammer. A mounting hole is opened at the end of the guide rod away from the mounting plate.
[0007] As a further embodiment of this utility model: the external positioning mechanism includes a mounting ring, a rotating ring is slidably connected to the inner wall of the front side of the mounting ring, the inner diameter of the mounting ring and the rotating ring are the same, and the inner side wall of the mounting ring is fixedly installed to the outer wall of the mounting plate. Mounting seats are fixedly installed on both sides of the outer wall of the mounting ring, and threaded mounting holes are provided around the end face of the mounting seats.
[0008] As a further embodiment of this utility model: an outer guide rail is fixedly connected to the outer wall of the front side of the mounting ring, and each of the outer guide rails is arranged equidistantly around the central axis of the rotating ring. A number of bolts are threaded through and connected to the outer wall of the mounting ring, and the ends of each bolt abut against the outer wall of the rotating ring.
[0009] As a further embodiment of this utility model: each of the rotating ring surfaces near each of the outer guide rails is provided with an extrusion groove 2, and each of the extrusion groove 2 is slidably connected to an outer ring pressure rod, each of the outer ring pressure rods is respectively connected to the inner side of the outer guide rail through and slidably connected, and each of the outer guide rails is provided with a distance scale in its own length direction on its surface.
[0010] As a further embodiment of this utility model: the two end faces of the outer ring pressure rod and the two end faces of the inner ring pressure rod are respectively located on the same vertical plane.
[0011] The beneficial effects of this utility model are: This invention features multiple inner ring pressure rods on the outer side of the mounting plate, a fixed mounting ring on the outer side of the mounting plate, and multiple outer ring pressure rods on the outer side of the mounting plate. When the inner ring pressure rods press against the inner ring of the bearing, the outer ring pressure rods simultaneously press against the outer ring of the bearing. When installing the embedded bearing, the operator can use a hammer to strike the mounting plate and mounting ring along the guide rod on the back of the device. This causes the inner and outer ring pressure rods to apply pressure to the inner and outer rings of the bearing simultaneously, making the inner ring of the bearing fit with the shaft and the outer ring fit with the bearing housing. This improves installation efficiency and facilitates damage-free installation of the bearing.
[0012] Each inner ring pressure bar can move radially along the mounting plate simultaneously to accommodate bearing inner rings of different sizes, and each outer ring pressure bar can also move radially along the mounting plate simultaneously to accommodate bearing outer rings of different sizes. Thus, this fixture can accommodate bearings of various specifications and is easy to adjust. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figure 1-4 As shown, a tooling fixture for mounting an embedded bearing includes an inner positioning mechanism 1, with an outer positioning mechanism 2 disposed on the outer side of the inner positioning mechanism 1. The inner positioning mechanism 1 includes a mounting plate 101, with inner guide rails 107 fixedly connected to the outer wall of the front side of the mounting plate 101. The inner guide rails 107 are equidistantly arranged around the axial direction of the mounting plate 101. A turntable 108 is rotatably connected to the inner wall of the front side of the mounting plate 101. Each inner guide rail 107 has a pressing groove 109 on its surface near the inner guide rails 109. Each inner ring pressure rod 115 is slidably connected to the inner wall of the pressing groove 109. The middle part of each inner ring pressure rod 115 is slidably connected to the inner guide rail 107. Each inner guide rail 107 has a distance scale along its length direction on its surface. Figure 1 , Figure 4 As shown, the distance between the outer ring pressure rod 206 or the inner ring pressure rod 115 and the axis can be determined by the scale on the surface of the inner guide rail 107 and the outer guide rail 203.
[0018] An end plate 112 is fixedly mounted on the upper part of the front outer wall of the mounting plate 101. An arc-shaped groove 113 is formed on the surface of the end plate 112. A sliding shaft 110 is slidably connected to the inner wall of the arc-shaped groove 113. A mounting hole 111 is formed in the middle of the end face of the sliding shaft 110. A bolt 114 is threaded into the inner wall of the mounting hole 111, and the end face of the bolt 114 mates with an anti-slip washer and abuts against the surface of the end plate 112. The sliding shaft 110 is fixed to the front edge of the turntable 108. Figure 4 As shown, after bolt 114 is tightened, it abuts against the surface of end plate 112, thereby obstructing the movement of slide shaft 110 along arc groove 113.
[0019] A support pad 102 is adhered and fixed to the center of the back of the mounting plate 101. A guide rod 103 is connected through the inner side of the support pad 102, and the end of the guide rod 103 is fixedly installed to the back of the mounting plate 101. A swing hammer 105 is slidably sleeved on the outer wall of the guide rod 103. A handle 106 is fixedly connected to one side of the outer wall of the swing hammer 105. A mounting hole 104 is opened at the end of the guide rod 103 away from the mounting plate 101. Figure 2 As shown, mounting hole 104 can be used with fasteners to connect an external auxiliary grip, making it convenient for operators to grip and position. Support pad 102 can be made of engineering plastic or rubber.
[0020] The external positioning mechanism 2 includes a mounting ring 201, with a rotating ring 204 slidably connected to the inner wall of the front side of the mounting ring 201. The inner diameters of the mounting ring 201 and the rotating ring 204 are the same, and the inner side wall of the mounting ring 201 is fixedly installed to the outer wall of the mounting plate 101. Mounting seats 207 are fixedly installed on both sides of the outer wall of the mounting ring 201, and threaded mounting holes are provided around the end face of the mounting seats 207. Figure 1 As shown, mounting base 207 can be used with fasteners to connect an external auxiliary grip or bracket.
[0021] An outer guide rail 203 is fixedly connected to the outer wall of the mounting ring 201. Each outer guide rail 203 is equidistantly arranged around the central axis of the rotating ring 204. Several bolts 202 are threaded through and connected to the outer wall of the mounting ring 201. The end of each bolt 202 abuts against the outer wall of the rotating ring 204. Figure 3 As shown, the tightened bolt 202 prevents the rotating ring 204 from rotating inside the mounting ring 201.
[0022] Each outer guide rail 203 has a second extrusion groove 205 on its surface near the outer ring 204. An outer ring pressure rod 206 is slidably connected to the inner side of each extrusion groove 205. Each outer ring pressure rod 206 penetrates and slidably connects to the inner side of the outer guide rail 203. Each outer guide rail 203 has distance markings along its length on its surface. Figures 1-4As shown, anti-detachment grooves are provided on the inner sides of both the outer guide rail 203 and the inner guide rail 107. The middle side of the outer ring pressure rod 206 and the inner ring pressure rod 115 slides along the anti-detachment groove, thereby preventing the outer ring pressure rod 206 and the inner ring pressure rod 115 from detaching from the device after being vibrated. The second extrusion groove 205 and the first extrusion groove 109 are both at a 45-degree angle to the adjacent outer guide rail 203 or inner guide rail 107.
[0023] The end faces of the outer ring compression member 206 and the end faces of the inner ring compression member 115 are located on the same vertical plane, as shown below. Figure 1 As shown, during bearing installation, it can be ensured that both the inner and outer rings of the bearing are subjected to axial pressure simultaneously.
[0024] The working principle of this utility model: When the device is in use, the shaft is installed in the bearing housing, ensuring that the shaft and the bearing housing are concentric. Then, the embedded bearing is installed between the bearing housing and the shaft, with the inner ring of the bearing mating with the shaft and the bearing fully mating with the bearing housing. After that, the inner ring pressure rod 115 is pressed against the inner ring of the bearing, and the outer ring pressure rod 206 is pressed against the outer ring of the bearing. The operator controls the swing hammer 105 through the handle 106. The swing hammer 105 strikes the support pad 102, so that the inner ring pressure rod 115 and the outer ring pressure rod 206 both apply pressure in the axial direction of the bearing, thereby gradually pushing the inner ring and the outer ring of the bearing into place. Secondly, when adjusting the spacing of the outer ring pressure rods 206, the rotating ring 204 can be rotated, and the outer ring pressure rods 206 in the outer guide rail 203 can be pushed to slide simultaneously through the extrusion groove 205. When fixing, tighten the bolt 202 on the outside of the mounting ring 201. The bolt 202 abuts against the side of the rotating ring 204 to prevent it from rotating. When adjusting the spacing of the inner ring pressure rods 115, rotate the turntable 108, and the extrusion groove 109 pushes the inner ring pressure rods 115 in the inner guide rail 107 to slide simultaneously. When fixing, tighten the bolt 114. The end of the bolt 114, in conjunction with the anti-slip washer, abuts against the surface of the end plate 112 to prevent the sliding shaft 110 and the turntable 108 from rotating.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
