Abstract
Description
Technical Field
[0001] The utility model belongs to the field of bearing removal devices, in particular to a sliding bearing removal device. Background Art
[0002] Sliding bearings are characterized by stability, reliability, low noise, and simple structure, so they are widely used in mechanical products. When a sliding bearing is damaged and needs to be replaced, the damaged sliding bearing needs to be removed, otherwise the entire part will be scrapped. The existing sliding bearing removal method generally uses a tool to push or pull out the sliding bearing, or cuts the sliding bearing and then removes it. When removing it, a threaded tool needs to be screwed onto the sliding bearing, but the inner and outer rings of the bearing will rotate relative to each other, making the tool inconvenient to install. Therefore, we have invented a sliding bearing removal tool that is not affected by the rotation of the inner and outer rings of the bearing. Utility Model Content
[0003] The utility model provides a sliding bearing removal device, which is used to solve the defects in the prior art.
[0004] The utility model is achieved through the following technical solutions:
[0005] A sliding bearing removal device includes a pressure rod, which is provided with two left and right pressure rods. The same nut is fixedly installed on the pressure rod, and the internal thread of the nut is connected to the threaded rod. A push block is rotatably installed on the threaded rod. The bottom of the push block is hemispherical. Slide sleeves are slidably installed on the pressure rod, and an arc-shaped vertical rod is fixedly installed on the sliding sleeve. An arc block is fixedly installed on the opposite side of the arc-shaped vertical rod. The push block can contact and cooperate with the arc block. The outer sides of the arc-shaped vertical rods are respectively provided with threads that can cooperate with the sliding bearing threads.
[0006] In the sliding bearing removal device as described above, a handle is fixedly mounted on the threaded rod.
[0007] In the sliding bearing removal device as described above, the side surfaces of the push block relative to the arc-shaped block are respectively flat.
[0008] In the sliding bearing removal device as described above, threaded holes are respectively provided on the arc-shaped vertical rods, and the internal threads of the threaded holes are adapted to fit the mounting bolts.
[0009] The advantages of the present invention are as follows: the present invention has a simple structure and an ingenious design; the threads on the arc-shaped vertical rod can be matched with the threads on the sliding bearing by moving the arc-shaped vertical rod outward, and the arc-shaped vertical rod does not need to be screwed onto the sliding bearing, thereby avoiding the influence caused by the mutual rotation of the inner and outer rings of the sliding bearing. The present invention can meet actual needs and is suitable for promotion. When it is necessary to remove the sliding bearing from a part, the pressure rod is placed on the part, and then the threaded rod is rotated to move it downward and drive the push block to move together. When the push block contacts the arc block, the push block gives the arc block a thrust, pushing it to move to both sides, and at the same time drives the arc-shaped vertical rod to move along the pressure rod, thereby approaching the sliding bearing until the threads on the arc block and the threads on the sliding bearing are matched. At this time, the threaded rod and the pressure rod are pulled upward to drive the arc block upward, and then the sliding bearing is driven upward by the thread, and the sliding bearing can be removed.

[0013] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0014] A sliding bearing removal device, such as Figure 1 、 2As shown in Figure 3, it includes a pressure rod 1, which is provided with two left and right parts. The same nut 4 is fixedly installed on the pressure rod 1. The internal thread of the nut 4 is connected to the threaded rod 2. The push block 3 is rotatably installed on the threaded rod 2. The bottom of the push block 3 is hemispherical. Slide sleeves 5 are slidably installed on the pressure rod 1. The slide sleeves 5 are fixedly installed on the arc-shaped vertical rods 6. The arc blocks 7 are fixedly installed on the opposite sides of the arc-shaped vertical rods 6. The push blocks 3 can contact and cooperate with the arc blocks 7. The outer sides of the arc-shaped vertical rods 6 are respectively provided with threads that can cooperate with the threads of the sliding bearings 100. The utility model has a simple structure and an ingenious design. By moving the arc-shaped vertical rods 6 outward, the threads on them can cooperate with the threads on the sliding bearings 100. There is no need to screw the arc-shaped vertical rods 6 onto the sliding bearings 100, which avoids the influence of the mutual rotation of the inner and outer rings of the sliding bearings 100. It can meet actual needs and is suitable for promotion. When the sliding bearing 100 on the part 101 needs to be removed, the pressure rod 1 is placed on the part 101, and then the threaded rod 2 is rotated to move it downward and drive the push block 3 to move together. When the push block 3 contacts the arc block 7, the push block 3 gives the arc block 7 a thrust, pushing it to both sides, and at the same time drives the arc vertical rod 6 to move along the pressure rod 1, thereby approaching the sliding bearing 100, until the thread on the arc block 7 matches the thread on the sliding bearing 100. At this time, pull the threaded rod 2 and the pressure rod 1 upward to drive the arc block 7 to move upward, and then drive the sliding bearing 100 upward through the thread, and the sliding bearing 100 can be taken out.
[0015] Specifically, as shown in the figure, the threaded rod 2 of this embodiment is fixed with a handle 20. Rotating the threaded rod 2 through the handle 20 is more convenient and labor-saving.
[0016] Specifically, as shown in the figure, the side surfaces of the push block 3 relative to the arc block 7 in this embodiment are respectively plane. Setting the side surfaces of the push block 3 as planes can better fit with the push block 3, thereby making it more stable to apply thrust to the arc block 7.
[0017] Furthermore, as shown in the figure, threaded holes are respectively provided on the arc-shaped vertical rods 6 of this embodiment, and the internal threads of the threaded holes cooperate with the mounting bolts 40. When the bottom of the sliding bearing 100 is not in contact with the part 101, the bolts 40 can be screwed so that their outer ends extend beyond the corresponding arc-shaped vertical rods 6. When the threaded rod 2 approaches the sliding bearing 100, the bolts 40 are driven to move together. After the threaded rod 2 contacts the sliding bearing 100, the bolts 40 are located on the lower side of the sliding bearing 100. When the threaded rod 2 is pushed upward to pull out the sliding bearing 100, the bolts 40 will also give the sliding bearing 100 a thrust, thereby making it easier to remove the sliding bearing 100.
[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
