Description

Technical Field

[0001] The utility model relates to the technical field of deep groove ball bearing press-fitting, in particular to a deep groove ball bearing press-fitting device. Background Art

[0002] Deep groove ball bearings, formerly known as radial ball bearings, are the most widely used rolling bearings. The basic deep groove ball bearings consist of an outer ring, an inner ring, a set of steel balls and a set of cages.

[0003] When assembling deep groove ball bearings manually, it is necessary to manually fit the inner ring onto the inner side of the outer ring first, and make the inner ring tend to fit the inner side of the outer ring, so that there is a large gap between the inner ring and the other inner side of the outer ring. Then, place a group of steel balls at the large gap, and then maintain the whole in this state, and slowly place it on a press-fitting workbench, so that the inner ring remains stationary and the outer ring is squeezed, so as to complete the press-fitting operation of the inner ring, outer ring and steel balls. During this process, in order to ensure the stability of the posture of the inner ring and the outer ring, the staff needs to apply squeezing force to them with their hands all the time, which increases the staff's hand fatigue. In order to simplify the hand's maintenance action on the position of the inner ring and the outer ring, so as to achieve the purpose of improving the press-fitting work efficiency, a press-fitting device for deep groove ball bearings is provided. Utility Model Content

[0004] The utility model aims to provide a deep groove ball bearing press-fitting device in order to further improve the working efficiency of manual press-fitting of deep groove ball bearings.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a press-fitting device for a deep groove ball bearing, comprising a press-fitting table, a quick press assembly is arranged on the top of the press-fitting table, and the quick press assembly is used to realize a quick press-fitting operation between an inner ring, an outer ring and a steel ball;

[0006] The quick pressing assembly includes a positioning unit and a pressing unit;

[0007] The positioning unit is used to realize the limited placement of the inner ring and outer ring of different diameters, so as to facilitate the installation of the steel ball, and the press-fitting unit is used to realize the press-fitting operation between the inner ring, the outer ring and the steel ball;

[0008] The positioning unit includes a positioning column, a convex sliding groove, a convex sliding block, a connecting rod, and a first V-shaped pressing plate;

[0009] There are two positioning posts, and the two positioning posts are symmetrically fixed on the top of the press-fitting table;

[0010] The convex slide groove is opened inside the press-fitting platform and passes through the top of the press-fitting platform. The convex slide groove is distributed at one end of the positioning column. The convex slider is slidably connected to the inner side of the convex slide groove and protrudes to the top of the press-fitting platform and is fixedly connected to the connecting rod. The first V-shaped pressing plate is fixed to one end of the connecting rod away from the convex slider, and the first V-shaped pressing plate is close to the positioning column.

[0011] The inner ring and the outer ring are placed between the positioning column and the first V-shaped pressure plate, the inner side of the inner ring is limited by the positioning column, and the outer side of the outer ring is limited by the first V-shaped pressure plate, so that the inner ring is placed close to the inner side of the outer ring;

[0012] The distance between the first V-shaped pressure plate and the positioning column is adjusted by the cooperation of the convex sliding block and the convex sliding groove, so as to limit the inner ring and outer ring of different diameters.

[0013] As a further solution of the utility model: the positioning unit further includes a compression spring;

[0014] The compression spring is arranged inside the convex slide groove and the two ends of the compression spring are respectively in contact with the end surface of the convex slider and the end surface of the inner wall of the convex slide groove.

[0017] The electric push rod drives the second V-shaped pressure plate close to the positioning column to push the inner ring, outer ring and steel ball as a whole. When the other inner side of the inner ring is squeezed and fitted with the positioning column, the outer ring is further pushed by the second V-shaped pressure plate to achieve relative displacement with the inner ring, thereby realizing the press-fitting of the inner ring, outer ring and steel ball.

[0018] As a further solution of the present invention: the second V-shaped pressure plate is symmetrically distributed with the first V-shaped pressure plate, and the symmetric midlines of the two positioning columns coincide with the mid-axis lines of the second V-shaped pressure plate and the first V-shaped pressure plate.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 3 In the embodiment of the utility model, a press-fitting device for a deep groove ball bearing comprises a press-fitting platform 1, a quick press assembly 2 is arranged on the top of the press-fitting platform 1, and the quick press assembly 2 is used to realize a quick press-fitting operation between an inner ring 3, an outer ring 4 and a steel ball;

[0029] The quick pressing assembly 2 includes a positioning unit and a pressing unit;

[0030] The positioning unit is used to realize the limited placement of the inner ring 3 and the outer ring 4 of different diameters, so as to facilitate the installation of the steel ball. The press-fitting unit is used to realize the press-fitting operation between the inner ring 3, the outer ring 4 and the steel ball.

[0031] The positioning unit includes a positioning column 201, a convex sliding groove 202, a convex sliding block 203, a connecting rod 204, and a first V-shaped pressing plate 205;

[0032] There are two positioning posts 201, and the two positioning posts 201 are symmetrically fixed on the top of the press-fitting platform 1;

[0033] The convex chute 202 is opened inside the press-fitting platform 1 and passes through the top of the press-fitting platform 1. The convex chute 202 is distributed at one end of the positioning column 201. The convex slider 203 is slidably connected to the inner side of the convex chute 202 and protrudes to the top of the press-fitting platform 1 and is fixedly connected to the connecting rod 204. The first V-shaped pressing plate 205 is fixed to one end of the connecting rod 204 away from the convex slider 203, and the first V-shaped pressing plate 205 is close to the positioning column 201.

[0034] The inner ring 3 and the outer ring 4 are placed between the positioning column 201 and the first V-shaped pressing plate 205. The inner side of the inner ring 3 is limited by the positioning column 201, and the outer side of the outer ring 4 is limited by the first V-shaped pressing plate 205, so that the inner ring 3 is placed close to the inner side of the outer ring 4.

[0035] The distance between the first V-shaped pressing plate 205 and the positioning column 201 is adjusted by the cooperation between the convex sliding block 203 and the convex sliding groove 202, so as to limit the inner ring 3 and the outer ring 4 of different diameters;

[0036] The positioning unit further includes a compression spring 206, which is disposed inside the convex slide groove 202 and whose two ends are respectively in contact with the end surface of the convex slider 203 and the inner wall end surface of the convex slide groove 202, so that the compression spring 206 is used to provide a thrust toward the positioning column 201 for the first V-shaped pressure plate 205.

[0037] The press-fitting unit includes an electric push rod 207 and a second V-shaped pressing plate 208;

[0038] The electric push rod 207 is fixed on the top of the press-fitting table 1 and is located at one end of the positioning column 201 away from the compression spring 206. The second V-shaped pressing plate 208 is fixed at the output end of the electric push rod 207 and is close to the positioning column 201.

[0039] The second V-shaped pressure plate 208 is driven by the electric push rod 207 to approach the positioning column 201, so that the second V-shaped pressure plate 208 pushes the inner ring 3, the outer ring 4 and the steel ball as a whole. When the other inner side of the inner ring 3 is squeezed and fitted with the positioning column 201, the outer ring 4 is continued to be pushed by the second V-shaped pressure plate 208 to achieve relative displacement with the inner ring 3, thereby realizing the press-fitting of the inner ring 3, the outer ring 4 and the steel ball.

[0040] In this embodiment: when the deep groove ball bearing is press-fitted, the inner ring 3 and the outer ring 4 can be sleeved and placed as a whole on the press-fitting table 1, so that the inner ring 3 is sleeved on the outside of the positioning column 201, and the outer ring 4 squeezes the first V-shaped pressing plate 205 to move, and the first V-shaped pressing plate 205 pushes the convex sliding block 203 to move along the inner wall of the convex sliding groove 202 through the connecting rod 204, and further squeezes the compression spring 206, and finally the inner ring 3 and the outer ring 4 are located between the positioning column 201 and the first V-shaped pressing plate 205;

[0041] Then, the grip on the inner ring 3 and the outer ring 4 is released. At this time, under the restoring elastic force of the compression spring 206, the first V-shaped pressing plate 205 is reset and moves and pushes the inner ring 3 and the outer ring 4 to approach the positioning column 201. Finally, the inner wall of the inner ring 3 is attached to the two positioning columns 201, the first V-shaped pressing plate 205 is pressed against the outer side of the outer ring 4, and one side of the outer side of the inner ring 3 is attached to one side of the inner side of the outer ring 4, and the other side of the outer side of the inner ring 3 and the other side of the inner side of the outer ring 4 are in a state of large gap.

[0042] Then, a corresponding number of steel balls are placed in the middle of the larger gap, and then the electric push rod 207 is started. The electric push rod 207 drives the second V-shaped pressure plate 206 to move closer to the positioning column 201. The second V-shaped pressure plate 206 first contacts the outer ring 4 and pushes the outer ring 4 to move. At this time, the outer ring 4 pushes the inner ring 3 to move synchronously through the steel balls, and pushes the first V-shaped plate 205 to move synchronously.

[0043] When the other side of the inner ring 3 contacts the positioning column 201, the inner ring cannot move further, while the outer ring 4 continues to move, that is, the relative displacement of the outer ring 4 and the inner ring 3 is realized. At this time, the steel ball is subjected to a large extrusion force, and the steel ball is stuck in the groove inside the outer ring 4 and outside the inner ring 3, thereby realizing the press-fitting operation of the outer ring 4, the inner ring 3 and the steel ball;

[0044] After completing the press-fitting operation, the electric push rod 207 is reset, and the pressed deep groove ball bearing is taken out, and then the above operation is repeated. Compared with the traditional manual operation of maintaining the position of the inner ring 3 and the outer ring 4, and continuing to keep the state unchanged after placing the steel ball, and placing it on the press-fitting table, it not only reduces the work intensity of the staff, but also improves the overall work efficiency.

[0045] Please refer to Figures 1 to 3 The second V-shaped pressing plate 208 and the first V-shaped pressing plate 205 are symmetrically distributed, and the symmetrical midlines of the two positioning columns 201 coincide with the mid-axes of the second V-shaped pressing plate 208 and the first V-shaped pressing plate 205 .

[0046] In this embodiment: through this structure, the two positioning columns 201 and the center lines of the first V-shaped pressure plate 205 or the second V-shaped pressure plate 208 can be distributed in a triangle, so that the inner ring 3 and the outer ring 4 can maintain a stable center line alignment state during the press-fitting process.

[0047] Please refer to Figures 1 to 3 Two compression springs 206 are provided inside the convex slide groove 202, and the two compression springs 206 are symmetrically distributed about the central axis of the convex slide block 203;

[0048] When the convex sliding block 203 is located at the position closest to the positioning column 201 , the convex sliding block 203 is still in the retracted state.

[0049] In this embodiment, the compression spring 206 can provide sufficient thrust for the first V-shaped pressing plate 205, thereby ensuring that the positions of the outer ring 4 and the inner ring 3 are fixed. In addition, the first V-shaped pressing plate 205 can move horizontally so that it will not interfere with the subsequent press-fitting operation. At the same time, it can adapt to the position limiting and press-fitting operations of the inner ring 3 and the outer ring 4 of different diameters.

[0050] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
