Description

Technical Field

[0001] This utility model relates to the field of bearing assembly technology, and in particular to a bearing assembly clamping device. Background Technology

[0002] A bearing assembly clamping device is a specialized piece of equipment used to apply pressure to the bearing during the assembly process of the bearing with the shaft, bearing housing, and other mating components, so that the bearing is pressed into the target position. Its core function is to avoid bearing damage caused by rough assembly methods such as manual hammering, while improving assembly efficiency.

[0003] When using the bearing assembly clamping device, the bearing needs to be installed on the inner wall of the limiting ring, and then the bearing is squeezed by the clamping rod. However, in order to facilitate the installation and removal of the bearing, the inner diameter of the limiting ring is slightly larger than the outer diameter of the bearing. This causes the bearing to shift on the inner wall of the limiting ring during the bearing assembly process, which may lead to the problem of loose bearing assembly. Utility Model Content

[0004] This invention provides a bearing assembly clamping device to address the problem that during bearing assembly, the bearing may shift within the inner wall of the limiting ring, potentially leading to loose bearing assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bearing assembly and clamping device, comprising a base, a frame fixedly installed on the top of the base, a cylinder telescopic rod installed on the top of the frame, a movable plate fixedly installed at one end of the cylinder telescopic rod, the movable plate being slidably installed on the inner wall of the frame, a pressing rod fixedly installed at the bottom of the movable plate, a limiting ring installed in the middle of the top of the base, and an auxiliary device provided on the outer surface of the limiting ring, the auxiliary device providing auxiliary fixing of the bearing by setting a rubber ring at the bottom of the limiting ring to abut against the bearing.

[0006] The effect achieved by the above components is as follows: by setting the rubber ring and adjusting the rubber ring so that the outer surface of the rubber ring abuts against the outer surface of the bearing, the rubber ring can provide auxiliary fixation between the limiting ring and the bearing, which helps to prevent the bearing from shifting on the inner wall of the limiting ring during assembly, thereby making the bearing assembly tighter.

[0007] Preferably, the auxiliary device includes a cylinder fixedly installed at the middle of the top of the base, a limiting ring disposed inside the cylinder, a rubber ring disposed between the cylinder and the limiting ring, the rubber ring being fixedly installed at the top of the base, an external threaded cylinder disposed at the top of the rubber ring, the external threaded cylinder being threadedly connected to the inner wall of the cylinder, and four through holes evenly provided at the bottom of the limiting ring.

[0008] The effect achieved by the above components is as follows: rotating the external threaded cylinder causes it to expand and contract within the inner wall of the cylinder. The external threaded cylinder compresses the rubber ring, causing it to deform and pass through the inner wall of the through hole until the outer surface of the rubber ring completely contacts the outer surface of the bearing placed in the limiting ring. The friction between the rubber ring and the bearing can then provide auxiliary fixation between the limiting ring and the bearing, which helps to prevent the bearing from shifting within the inner wall of the limiting ring during assembly.

[0009] Preferably, the rubber ring has a hollow structure.

[0010] The effect achieved by the above components is that by setting a hollow rubber ring, the deformation capacity of the rubber ring can be increased, making it easier to adjust the degree of deformation of the rubber ring, so that the rubber ring can play a better role in fixing the bearing.

[0011] Preferably, a silicone ring is fixedly installed at one end of the external threaded cylinder, the silicone ring is disposed between the cylinder and the limiting ring, and one side of the silicone ring abuts against one side of the rubber ring.

[0012] The effect achieved by the above-mentioned components is that by setting a silicone ring, one end of the external threaded cylinder can be used to abut against one side of the rubber ring, which can play a certain protective role for the rubber ring and help prevent the external threaded cylinder from excessively squeezing the rubber ring, causing the hollow rubber ring to break.

[0013] Preferably, the top of the inner wall of the limiting ring is provided with a bevel.

[0014] The effect achieved by the above components is that by setting a bevel at the top of the inner wall of the limiting ring, the inner diameter of the bevel at the top is larger and becomes smaller towards the bottom, making it easier to insert the bearing into the limiting ring.

[0015] Preferably, an operating ring is fixedly installed at the other end of the external threaded cylinder, and the outer surface of the operating ring is uniformly provided with protrusions.

[0016] The effect achieved by the above components is as follows: by setting the operating ring, rotating the operating ring can drive the external threaded cylinder to rotate. At the same time, the outer surface of the operating ring is provided with protrusions, which can effectively increase the friction of the outer surface of the operating ring and have an anti-slip effect when rotating the operating ring.

[0017] Preferably, a plurality of screw hole blocks are fixedly installed at the bottom of the operating ring, and bolts are threaded into the inner wall of the screw hole blocks.

[0018] The effect achieved by the above components is as follows: when the bolt is rotated, one end of the bolt passes through the inner wall of the threaded hole block until one end of the bolt abuts against the outer surface of the cylinder. The bolt can then provide auxiliary fixation between the external threaded cylinder and the cylinder, which helps to prevent the external threaded cylinder from loosening and causing the rubber ring to reset.

[0019] Preferably, a rubber sleeve is fixedly installed on the outer surface of the cylinder, and the bolt is located on one side of the rubber sleeve.

[0020] The effect achieved by the above components is that by setting a rubber sleeve, the outer surface of the cylinder can be replaced to abut against one end of the bolt, and the friction between the bolt and the cylinder can be increased, making the bolt more securely fixed to the external threaded cylinder.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting a rubber ring and adjusting the rubber ring so that the outer surface of the rubber ring abuts against the outer surface of the bearing, the rubber ring can provide auxiliary fixation between the limiting ring and the bearing, which helps to prevent the bearing from shifting on the inner wall of the limiting ring during assembly, thereby making the bearing assembly tighter.

[0024] Example 1, referring to Figures 1-3As shown, this embodiment discloses a bearing assembly clamping device, including a base 1, a frame 2 fixedly installed on the top of the base 1, a cylinder telescopic rod 3 installed on the top of the frame 2, a movable plate 4 fixedly installed at one end of the cylinder telescopic rod 3, the movable plate 4 slidably installed on the inner wall of the frame 2, a pressing rod 5 fixedly installed at the bottom of the movable plate 4, a limiting ring 6 installed in the middle of the top of the base 1, and an auxiliary device 7 provided on the outer surface of the limiting ring 6. The auxiliary device 7 provides auxiliary fixing of the bearing by setting a rubber ring 72 at the bottom of the limiting ring 6 to abut against the bearing. By setting the rubber ring 72 and adjusting the rubber ring 72 so that the outer surface of the rubber ring 72 abuts against the outer surface of the bearing, the rubber ring 72 can provide auxiliary fixing between the limiting ring 6 and the bearing, which helps to prevent the bearing from shifting on the inner wall of the limiting ring 6 during the assembly process, thereby making the bearing assembly tighter.

[0025] Reference Figures 2-4 As shown, the auxiliary device 7 includes a cylinder 71, which is fixedly installed in the middle of the top of the base 1. A limiting ring 6 is disposed inside the cylinder 71. A rubber ring 72 is disposed between the cylinder 71 and the limiting ring 6. The rubber ring 72 is fixedly installed on the top of the base 1. An externally threaded cylinder 73 is disposed on the top of the rubber ring 72. The externally threaded cylinder 73 is threadedly connected to the inner wall of the cylinder 71. Four through holes 74 are evenly opened at the bottom of the limiting ring 6. When the externally threaded cylinder 73 is rotated, it expands and contracts within the inner wall of the cylinder 71, thus squeezing the rubber ring 72 and causing it to rotate. The rubber ring 72 deforms, allowing it to pass through the inner wall of the through hole 74 until its outer surface completely abuts against the outer surface of the bearing placed in the retaining ring 6. The friction between the rubber ring 72 and the bearing provides auxiliary fixation between the retaining ring 6 and the bearing, which helps prevent the bearing from shifting on the inner wall of the retaining ring 6 during assembly. The rubber ring 72 is hollow, which increases its deformation capacity and makes it easier to adjust the degree of deformation, thus enabling the rubber ring 72 to provide a better fixing effect on the bearing.

[0026] Reference Figures 2-4 As shown, a silicone ring 75 is fixedly installed at one end of the external threaded cylinder 73. The silicone ring 75 is positioned between the cylinder 71 and the limiting ring 6. One side of the silicone ring 75 abuts against one side of the rubber ring 72. By setting the silicone ring 75, one end of the external threaded cylinder 73 can abut against one side of the rubber ring 72 instead, which can play a certain protective role for the rubber ring 72 and help prevent the external threaded cylinder 73 from excessively squeezing the rubber ring 72, causing damage to the hollow rubber ring 72. A bevel 76 is provided at the top of the inner wall of the limiting ring 6. By setting the bevel 76 at the top of the inner wall of the limiting ring 6, the inner diameter of the top of the bevel 76 is larger and decreases towards the bottom, making it easier to insert the bearing into the limiting ring 6.

[0027] Reference Figure 4 As shown, an operating ring 77 is fixedly installed at the other end of the external threaded cylinder 73. The outer surface of the operating ring 77 is uniformly provided with protrusions. By setting the operating ring 77, rotating the operating ring 77 can drive the external threaded cylinder 73 to rotate. At the same time, the protrusions on the outer surface of the operating ring 77 can effectively increase the friction of the outer surface of the operating ring 77, and have an anti-slip effect when rotating the operating ring 77.

[0028] Reference Figures 2-4 As shown, several screw hole blocks 78 are fixedly installed at the bottom of the operating ring 77. Bolts 79 are threaded into the inner wall of the screw hole blocks 78. By rotating the bolts 79, one end of the bolt 79 passes through the inner wall of the screw hole block 78 until one end of the bolt 79 abuts against the outer surface of the cylinder 71. The bolt 79 can then provide auxiliary fixation between the external threaded cylinder 73 and the cylinder 71, which helps to prevent the external threaded cylinder 73 from loosening and causing the rubber ring 72 to reset. A rubber sleeve 710 is fixedly installed on the outer surface of the cylinder 71. The bolt 79 is located on one side of the rubber sleeve 710. By setting the rubber sleeve 710, it can replace the outer surface of the cylinder 71 to abut against one end of the bolt 79 and increase the friction between the bolt 79 and the cylinder 71, making the fixation of the bolt 79 to the external threaded cylinder 73 more stable.

[0029] Working principle: The bearing is inserted into the limiting ring 6 through the bevel 76. The operating ring 77 is rotated, which drives the external threaded cylinder 73 to move on the inner wall of the cylinder 71. The external threaded cylinder 73 will drive the silicone ring 75 to squeeze the rubber ring 72, causing the hollow rubber ring 72 to deform. The rubber ring 72 will pass through the inner wall of the through hole 74 until the outer surface of the rubber ring 72 is completely in contact with the outer surface of the bearing placed in the limiting ring 6. Then, the bolt 79 is rotated so that one end of the bolt 79 passes through the inner wall of the threaded hole block 78 until one end of the bolt 79 is in contact with the rubber sleeve 710 on the outer surface of the cylinder 71. The bolt 79 can provide auxiliary fixation between the external threaded cylinder 73 and the cylinder 71, which helps to prevent the external threaded cylinder 73 from loosening and causing the rubber ring 72 to reset. The friction between the rubber ring 72 and the bearing can provide auxiliary fixation between the limiting ring 6 and the bearing, which helps to prevent the bearing from shifting on the inner wall of the limiting ring 6 during assembly.
