The embodiment provides a bearing press-in device 100, and the bearing press-in device 100 is used for pressing a bearing 200 into a bearing mounting hole arranged on a shaft seat 300, so that the bearing 200 and the shaft seat 300 can be assembled quickly and accurately. As shown in fig. 1 to 3, the bearing press-fitting device 100 includes a press-fitting body 1, a first tap structure 2, a second tap structure 3, and a sliding sleeve 4. The press-in body 1 is a rod-shaped structure, the two ends of the press-in body are respectively a first end 101 and a second end 102, the size of the first end 101 of the press-in body 1 is larger than that of the bearing mounting hole, and the size of the second end 102 of the press-in body 1 is smaller than that of the bearing mounting hole. First knocking structure 2 and second knocking structure 3 interval set up on the body 1 of impressing, and sliding sleeve 4 cover is established on the body 1 of impressing to be located between first knocking structure 2 and the second knocking structure 3, sliding sleeve 4 is lighter than the distance between first knocking structure 2 and the second knocking structure 3 along axial length, in order to realize sliding sleeve 4 and strike the removal between structure 2 and the second knocking structure 3. In the present exemplary embodiment, the first striker structure 2 is arranged close to a first end 101 of the press-in body 1, and the second striker structure 3 is arranged close to a second end 102 of the press-in body 1.
When the bearing 200 and the shaft seat 300 are assembled by using the bearing press-in device 100, the process includes two processes of initial assembly and deep assembly. During initial assembly, the bearing 200 is firstly arranged right above the bearing mounting hole; then aligning the first end 101 of the press-in body 1 with the bearing 200 and abutting the first end 101 of the press-in body 1 with the top surface of the bearing 200; finally, the sliding sleeve 4 is held by hand to move towards the direction of the first knocking structure 2 and hit the first knocking structure 2, so that the bearing 200 is gradually knocked into the bearing mounting hole until the top surface of the bearing 200 is flush with the top surface of the shaft seat 300 as shown in fig. 2, and at this time, the primary assembly of the bearing 200 and the shaft seat 300 is completed. During initial assembly, the size of the first end 101 is set to be larger than that of the bearing mounting hole, so that the size of the first end 101 is inevitably larger than that of the bearing 200, and therefore, the bearing press-in device 100 can be ensured to be in full contact with the bearing 200 at the initial stage of assembly of the bearing 200 and the shaft seat 300, so that the uniformity of force application is improved, and the bearing 200 is prevented from being deflected or damaged in the process of entering the bearing mounting hole.
Thereafter, deep assembly is possible, in which the entire bearing press-fitting device 100 is first reversed to align the second end 102 of the press-fitting body 1 with the bearing 200 and to bring the second end 102 of the press-fitting body 1 into contact with the top surface of the bearing 200; then, the handheld sliding sleeve 4 moves towards the second knocking structure 3 and hits the second knocking structure 3, so that the bearing 200 gradually moves towards the bottom of the bearing mounting hole until the bottom surface of the bearing 200 is aligned with the bottom surface of the bearing mounting hole in an abutting mode as shown in fig. 3, and at this time, the deep assembly of the bearing 200 and the shaft seat 300 is completed. During deep assembly, the size of the second end 102 is smaller than that of the bearing mounting hole, so that the second end 102 can enter the bearing mounting hole and knock the bearing 200 to the bottom of the bearing mounting hole, thereby improving the connection stability of the bearing 200 and the shaft seat 300 and preventing the bearing 200 from being separated from the bearing mounting hole in the working process.
This bearing push in device 100 is through set up sliding sleeve 4 between first knocking structure 2 and second knocking structure 3, compact structure not only, and utilizes sliding sleeve 4 to not equidirectional removal can beat first knocking structure 2 or second knocking structure 3, convenient operation. Therefore, the bearing press-in device 100 has strong specificity, can quickly and accurately realize the assembly of the bearing 200 and the shaft seat 300, and cannot easily damage the bearing 200 and the shaft seat 300 in the assembly process.
Alternatively, in the present embodiment, in order to make the bearing press-in device 100 compact and easy to manufacture, it is selected to integrally form the first knocking structure 2 and the press-in body 1. Further alternatively, as shown in fig. 1 to 3, the first striking structure 2 is disposed at the first end 101 of the press-in body 1 and is integrally formed with the first end 101, that is, the first striking structure 2 can be in contact with the bearing 200 as a part of the first end 101 of the press-in body 1, and such an arrangement can further improve the structure of the simplified bearing press-in device 100, making the structure of the bearing press-in device 100 more compact. Of course, in other embodiments, the first striking structure 2 may also be disposed in the middle of the press-in body 1, that is, the first striking structure 2 is located between the first end 101 of the press-in body 1 and the sliding sleeve 4, and in this case, the first end 101 of the press-in body 1 is a separate structure, and its own size needs to be larger than that of the bearing installation hole.
In particular, the first rapper structure 2 is a flange arranged along the circumference of the press-in body 1, optionally the first rapper structure 2 is a circular flange. The first knocking structure 2 includes two end faces arranged up and down, one of the end faces is a press-fitting plane, the other end face is a knocking plane, and the press-fitting plane is flush with the end face of the first end 101. Optionally, the press-fitting plane is perpendicular to the axis of the press-in body 1, and the knocking plane is perpendicular to the axis of the press-in body 1, so as to improve the knocking effect when the first knocking structure 2 knocks the bearing 200 and the sliding sleeve 4 knocks the first knocking structure 2.
In order to reduce the weight of the entire bearing press-fitting device 100 and to reduce the work intensity when an operator holds the device by hand, a through hole 103 is provided in the press-fitting body 1 in the axial direction. Since the bearing 200 includes the inner ring and the outer ring, in order to avoid the effect of the press-fitting of the first end 101 and the second end 102 of the press-fitting body 1, which is affected by the wall thickness of the press-fitting body 1 due to the arrangement of the through hole 103, the inner diameter of the through hole 103 is set to be smaller than or equal to the inner diameter of the bearing 200 in the present embodiment. Further, in order to improve the smoothness of the sliding sleeve 4 when sliding on the press-in body 1, the press-in body 1 is designed to be cylindrical, and the inner hole of the sliding sleeve 4 is formed as a circular hole.
In addition, since the first striking mechanism 2 is integrally formed with the press-in body 1, the sliding sleeve 4 cannot be attached from the first end 101 of the press-in body 1, and the second striking mechanism 3 is provided as a ring structure detachably connected to the press-in body 1 in order to facilitate the installation of the sliding sleeve 4 onto the press-in body 1 from the second end 102 of the press-in body 1. Specifically, as shown in fig. 1, the second knocking structure 3 is a pipe clamp, the pipe clamp includes a split ring 301, locking holes are provided at two ends of an opening of the split ring 301, and a locking member 302 passes through the locking holes to fix the split ring 301 on the pressing body 1. Of course, in other embodiments, the first rapping structure 2 may also be provided as a pipe clamp.
It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
