Description

Technical Field

[0001] The utility model relates to the technical field of roller assembly equipment, in particular to a stand for disassembling and assembling the inner ring of a roller bearing. Background Art

[0002] Rollers are crucial components and tools used in rolling mills to produce continuous plastic deformation of metals. They primarily consist of the roll body, roll neck, and shaft head. Because the roll neck is mounted within the mill's bearings, the bearing inner rings often need to be pre-installed on the roll neck before the rolls are assembled.

[0003] Typically, the bearing inner ring needs to be heated first, leveraging the principle of thermal expansion and contraction to facilitate smooth assembly onto the roll neck. A stand is required for this assembly process. Since the roll barrel is cylindrical, without a stand to secure it, the roll can easily roll during installation, preventing proper installation. Furthermore, the heated inner ring needs to be installed quickly. Without a dedicated stand, assembly time is significantly increased, and once the inner ring cools, it will not fit properly. Utility Model Content

[0004] The purpose of the utility model is to provide a stand for disassembling and assembling the inner ring of a roller bearing, which can effectively improve the assembly efficiency and assembly accuracy of the bearing inner ring.

[0005] According to the purpose of the present utility model, the present utility model provides a stand for disassembling and assembling the inner ring of a roller bearing, comprising a panel, a longitudinal baffle and two transverse baffles, the two transverse baffles being fixed on the top of the panel, the longitudinal baffle being fixed on the top of the panel, and a circular through hole being provided on the longitudinal baffle.

[0006] Furthermore, columns are fixed at the four corners of the bottom of the panel.

[0007] Furthermore, the two transverse baffles are spaced apart from each other.

[0008] Furthermore, the two transverse baffles are arranged parallel to each other.

[0009] Furthermore, the circular through hole is arranged at the bottom center of the longitudinal baffle.

[0010] Furthermore, a support plate is provided between the longitudinal baffle and the panel.

[0011] Furthermore, the support plate is arranged at an angle.

[0012] Furthermore, the bottom of the support plate is fixedly connected to the panel, and the top of the support plate is fixedly connected to the longitudinal baffle.

[0013] Furthermore, the transverse baffle is made of channel steel.

[0014] Furthermore, the longitudinal baffle is a steel plate with the circular through hole.

[0015] This utility model's technical solution effectively prevents the roller from rolling during the installation of the bearing inner ring by installing two transverse baffles on the panel. The longitudinal baffle with a circular through hole effectively prevents the roller from longitudinal movement during the assembly of the bearing inner ring, thereby ensuring that the heated bearing inner ring can be installed as quickly as possible, significantly reducing assembly time.

[0024] Example 1

[0025] like Figure 1-Figure 3 As shown:

[0026] A stand for disassembling and assembling the inner ring of a roller bearing comprises a panel 2 and two transverse baffles 3. Vertical columns 1 are welded and fixed at the four corners of the bottom of the panel 2. The two transverse baffles 3 are welded and fixed above the panel 2. There is space between the two transverse baffles 3 for accommodating the roller, and the two transverse baffles 3 are arranged parallel to each other.

[0027] The longitudinal baffle 4 is welded and fixed above the panel 2. A circular through hole for the roller neck 7 and the shaft head 8 to pass through is provided on the longitudinal baffle 4. The circular through hole is arranged at the bottom center position of the longitudinal baffle.

[0028] The support plate 5 is tilted and arranged between the longitudinal baffle 4 and the panel 2. The bottom of the support plate 5 is welded to the panel, and the top of the support plate 5 is welded to the longitudinal baffle 4. The support plate 5 supports the longitudinal baffle 4 to prevent it from deformation and improve its service life.

[0029] In this embodiment, channel steel is used as the transverse baffle 3 and welded to both sides of the panel 2. The use of channel steel can increase the contact area between the transverse baffle 3 and the panel 2, thereby preventing the transverse baffle 3 from deforming and improving its service life.

[0030] In this embodiment, the longitudinal barrier 4 is a steel plate with a circular through-hole. When the bearing inner ring 9 is assembled along the assembly direction, the roll neck 7 and shaft head 8 at one end of the roller pass through the circular through-hole, preventing the roller from moving longitudinally. The column 1 is constructed of steel pipe to increase the contact area between the column 1 and the ground and prevent movement during assembly.

[0031] like Figure 2 As shown, the roll is composed of a roll body 6, a roll neck 7 and a shaft head 8, and a bearing inner ring 9 is assembled onto the roll neck 7.

[0032] like Figure 3 As shown, when this device is in use, the roller body 6 is placed on the panel 2 and between the two transverse baffles 3. This effectively prevents the roller from rolling during the installation of the bearing inner ring. This facilitates the insertion of the roller neck 7 and the shaft head 8 through the circular through-holes in the longitudinal baffles 4. This effectively prevents longitudinal movement of the roller during the assembly of the bearing inner ring 9, ensuring that the heated bearing inner ring can be installed as quickly as possible, significantly reducing assembly time.

[0033] To ensure stable, convenient, and quick installation of the bearing inner ring 9, this utility model provides a low-cost, simple-structured stand for disassembling and assembling the inner ring of a roller bearing. This effectively improves assembly efficiency and precision of the bearing inner ring 9; the transverse baffle 3 significantly extends the service life of the structure; and the longitudinal baffles and columns with circular through-holes enhance the stability of the structure.

[0034] The utility model has a simple structure and low cost. The transverse baffle made of channel steel increases the contact area between the panel and the panel to prevent deformation. The longitudinal baffle with circular through holes, transverse baffles and columns can improve the stability of the structure in many aspects.

[0035] 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 above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
