Description

Technical Field

[0001] This utility model relates to the technical field of bearing disassembly devices, and more specifically, to rolling bearing disassembly fixtures. Background Technology

[0002] In the field of mechanical repair and assembly, the disassembly of rolling bearings is extremely common and important. When disassembling bearings, disassembly tools are generally used.

[0003] Existing tooling has an unreasonable structural design and poor stability when adjusting and fixing moving parts. During disassembly, it is easy for the clamping to become loose, causing the bearing to shift or even fall off. This may not only damage the bearing, but also pose a safety hazard to the operator. For example, some tooling relies on simple clips or friction to fix the clamping parts after adjusting their position. When a large disassembly force is applied, the fixing parts are easy to loosen. Therefore, a rolling bearing disassembly tooling is provided to solve the above-mentioned problems. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a rolling bearing disassembly fixture, which has the advantage of clamping and fixing bearings of different sizes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rolling bearing disassembly fixture, including a lever arm and slots. The lever arm has symmetrically opened slots, and there is a set of two lever arms. The internal thread of the lever arm is connected to a threaded pull rod, and both ends of the threaded pull rod pass through the interior of the lever arm. The two lever arms are slidably connected to a movable rod, and the movable rod is located in the two sets of slots respectively. One end of the movable rod is fixedly connected to a clamping plate.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, this utility model provides a rolling bearing disassembly fixture, including a lever arm 1 and slots 101. The lever arm 1 has symmetrical slots 101 and there is a set of two lever arms 1. The internal thread of the lever arm 1 is connected to a threaded pull rod 3, and both ends of the threaded pull rod 3 pass through the interior of the lever arm 1. The two lever arms 1 are slidably connected to a movable rod 2, and the movable rod 2 is located in the two sets of slots 101 respectively. One end of the movable rod 2 is fixedly connected to a clamping plate 4. The movable rod 2 includes a threaded post 201 threadedly sleeved inside the movable rod 2. A locking nut 202 is threadedly connected to the threaded post 201, and the locking nut 202 fixes the movable rod 2 to the lever arm 1.

[0021] At this point, the movable rod 2 is fixed by four sets of locking nuts 202, which makes it more secure and effectively prevents it from loosening.

[0022] A sliding block 203 is fixedly connected to the threaded post 201, and the sliding block 203 is slidably connected in the slot 101, with the two threaded posts 201 located at the two ends of the sliding block 203 respectively.

[0023] There are two sets of sliding blocks 203 on the moving rod 2. At this time, there are two sets of locking nuts 202 on each set of sliding blocks 203. Both sets of locking nuts 202 can be reversed to move them away from the lever arm 1, and then the moving rod 2 can be moved.

[0024] The lever arm 1 has a mounting rod 5 fixedly installed on its side, and a sliding groove is provided inside the mounting rod 5. A bidirectional screw 6 is rotatably installed in the sliding groove. A sliding ring 701 is threadedly connected to the outer surface of the bidirectional screw 6, and both ends of the bidirectional screw 6 pass through the two sliding rings 701 and the sliding rings 701 are slidably installed in the sliding groove. A mounting post 702 is fixedly connected to the outer surface of the sliding ring 701. A rotating rod 8 is rotatably installed inside the mounting post 702. A retaining ring 9 is fixedly connected to the end of the rotating rod 8 away from the sliding ring 701. The retaining ring 9 is threadedly sleeved on the outer surface of the threaded post 201.

[0025] By rotating the bidirectional screw 6, the two sets of mounting posts 702 move closer or further apart synchronously until the two moving rods 2 finally drive the two clamping plates 4 to abut against the bearing. Then, the locking nut 202 is tightened to fix the moving rods 2. At this time, by rotating the threaded pull rod 3, the threaded pull rod 3 gradually approaches the bearing. Since the two clamping plates 4 abut against the inner side of the bearing, there will be an upward supporting force. Thus, when the threaded pull rod 3 gradually squeezes the bearing, the bearing can be disassembled.

[0026] The mounting post 702 has an insertion hole 703 inside, and the rotating rod 8 is U-shaped. The end of the rotating rod 8 away from the retaining ring 9 is connected to the insertion hole 703.

[0027] After moving the moving rod 2, the retaining ring 9 can be removed from the threaded post 201 by pulling the rotating rod 8 upward. This setting is for easy use as needed. Beginners can disassemble the bearing by using the retaining ring 9, which increases clamping stability and avoids damage to the bearing caused by improper clamping.

[0028] The slot 101 is elliptical in shape and is located inside the lever arm 1.

[0029] The elliptical shape of the slot 101 facilitates the movement of the threaded post 201 inside the slot 101.

[0030] Among them, the threaded tie rod 3 is T-shaped, and the upper end of the threaded tie rod 3 is wide on both sides and narrow on the inside.

[0031] The threaded tie rod 3 is T-shaped, and the upper end of the threaded tie rod 3 is wider on both sides and narrower on the inside, which makes it easy for the staff to rotate the threaded tie rod 3.

[0032] The inner side of the clamp 4 is arc-shaped, and the two clamps 4 are in contact in a circular shape.

[0033] The inner side of the clamping plate 4 is arc-shaped, and the two clamping plates 4 are in contact with each other in a circular shape, which allows the clamping plate 4 to fit the bearing better and reduce misalignment caused by non-fitting.

[0034] Working principle and usage process of this utility model:

[0035] First, observe the dimensions of the rolling bearing to be disassembled. Place lever arm 1 in a suitable position so that it aligns with the disassembly direction of the bearing. This device uses two sets of lever arms 1, and there are two sets of sliding blocks 203 on the moving rod 2. At this time, there are two sets of locking nuts 202 on each set of sliding blocks 203. Both sets of locking nuts 202 can be reversed to move them away from lever arm 1. Then move the moving rod 2. At this time, simply pull the rotating rod 8 upward and rotate the rotating rod 8 so that the retaining ring 9 on the rotating rod 8 is fitted onto the threaded post 201 on the moving rod 2. At this time, one end of the rotating rod 8 is located in the insertion hole 703, and the other end... The end sleeve is connected to the threaded post 201. At this time, the nut can be rotated to release the fixation of the moving rod 2. Finally, the bidirectional screw 6 can be rotated to make the two sets of mounting posts 702 move closer or further away at the same time, until the two moving rods 2 finally drive the two clamping plates 4 to abut against the bearing. Then, the locking nut 202 is locked to fix the moving rod 2. At this time, by rotating the threaded pull rod 3, the threaded pull rod 3 gradually approaches the bearing. Since the two clamping plates 4 abut against the inner side of the bearing, there will be an upward supporting force. Thus, when the threaded pull rod 3 gradually squeezes the bearing, the bearing can be disassembled.
