Description

Technical Field

[0001] The utility model relates to the field of manufacturing spherical plain bearings, and particularly relates to a spherical plain bearing press-fitting and assembling mechanism. Background Art

[0002] A spherical plain bearing is a sliding bearing with a special structure, which mainly consists of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. The characteristics of this bearing are that it can bear large loads, including radial loads, axial loads or combined loads with both radial and axial loads existing simultaneously. Since the sliding surface of the spherical plain bearing is spherical, it can perform tilting motion (i.e., self-aligning motion) within a certain angle range, and is suitable for low-speed oscillating motion and low-speed rotation. Even when the concentricity between the supporting shaft and the hole of the shaft housing is relatively large, the spherical plain bearing can still work normally.

[0003] Spherical plain bearings have various characteristics, including simpler structure than rolling bearings, large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, good lubricity, etc. These characteristics enable spherical plain bearings to be widely used in industries such as engineering hydraulic cylinders, forging machines, construction machinery, automation equipment, automotive shock absorbers, and water conservancy machinery.

[0004] However, the existing press-fitting of spherical plain bearings is often carried out manually, and such a method cannot perform the assembling and press-fitting of spherical plain bearings well. Summary of the Utility Model

[0005] In order to overcome the above defects of the prior art, the purpose of the utility model is to provide a spherical plain bearing press-fitting and assembling mechanism. The utility model realizes no damage to the spherical plain bearing during press-fitting and assembling and saves the assembling time wasted under manual assembling through the improvement of the assembling structure.

[0006] In order to achieve the purpose of the utility model, the technical scheme adopted is:

[0007] A spherical plain bearing press-fitting and assembling mechanism, comprising:

[0008] A lower die structure, in which a spring mounting seat is arranged in the structure cavity of the lower die structure, a spring is axially arranged above the spring mounting seat, and a guide seat is arranged at the top of the spring;

[0009] A through hole is formed in the middle of the guide seat, a guide rod of the lower die passes through the mounting hole of the guide seat, and the lower end surface of the press-fitting platform of the lower die contacts or disengages from the upper end surface of the guide seat;

[0010] The upper end surface of the press-fitting platform of the lower die contacts the bottom of the spherical plain bearing to be press-fitted;

[0011] The upper die structure includes a mounting seat for a press-fitting structure. An upper die is arranged inside the mounting seat for the press-fitting structure. Driven by the mounting seat for the press-fitting structure, the upper die moves up and down axially to contact the upper part of the joint bearing to be press-fitted.

[0012] In a preferred embodiment of the present invention, a press-fitting chamber is arranged at the upper end of the structure cavity of the lower die structure, and the press-fitting platform of the lower die is arranged inside the press-fitting chamber.

[0013] In a preferred embodiment of the present invention, a plurality of mounting grooves are arranged on the outer periphery of the lower part of the structure cavity of the lower die structure. The structure cavity of the lower die structure is arranged on the working surface of an external press-fitting device by matching with the mounting grooves through fasteners.

[0014] The beneficial effects of the present invention are as follows:

[0015] Through the improvement of the sleeve assembling structure, the present invention realizes no damage to the joint bearing during press-fitting sleeve assembling and saves the sleeve assembling time wasted in manual sleeve assembling. Description of the Drawings

[0020] Such as Figure 1A joint bearing press-fitting and sleeving mechanism as described in item 2, comprising a lower die structure 100. A spring mounting seat 110 is arranged in a structure cavity 101 of the lower die structure 100. A spring 120 is axially arranged above the spring mounting seat 110. A guide seat 130 is arranged at the top of the spring 120.

[0021] A hole is opened in the middle of the guide seat 130. A guide rod 141 of the lower die 140 passes through the mounting hole of the guide seat 130, and the lower end surface of the press-fitting platform 142 of the lower die 140 contacts or disengages from the upper end surface of the guide seat 130. The upper end surface of the press-fitting platform 142 of the lower die 140 contacts the bottom of the joint bearing to be press-fitted (not shown in the figure).

[0022] A press-fitting chamber 102 is arranged at the upper end of the structure cavity 101 of the lower die structure 100. The press-fitting platform 142 of the lower die 140 is arranged in the press-fitting chamber 102.

[0023] A plurality of mounting grooves 103 are arranged on the outer periphery of the lower part of the structure cavity 101 of the lower die structure 100. The structure cavity 101 of the lower die structure 100 is arranged on the working surface of an external press-fitting device (not shown in the figure) by cooperating with the mounting grooves 103 through fasteners 300.

[0024] The upper die structure 200 includes a press-fitting structure mounting seat 210. An upper die 220 is arranged in the press-fitting structure mounting seat 210. The upper die 220 moves up and down axially under the drive of the press-fitting structure mounting seat 210 to contact the upper part of the joint bearing to be press-fitted (not shown in the figure).

[0025] With the elastic force of the spring 120 and the cooperation of the upper die structure 200 and the lower die structure 100, the inner ring of the bearing is fixed. The upper die 220 is moved by a press to contact the inner ring of the bearing sleeved on the guide seat 130 for sleeving until the appropriate position is reached.

[0026] The elastic force of the spring 120 is used to buffer the impact force during the closing process of the outer ring of the bearing during sleeving. Then, by using relative movement, the outer ring of the bearing is moved in the reverse direction to achieve bearing sleeving, so as to achieve no damage during the bearing sleeving process and save the time required for sleeving.
