Description

Technical Field

[0001] The utility model relates to the technical field of production of plain bearings, in particular to an assembly tooling for a self-locking plain bearing. Background Art

[0002] A needle roller thrust bearing is a special type of bearing, which belongs to one of the roller bearings. The diameter of the rollers is relatively small, but the length is relatively long. Such rollers are called needle rollers. The design of the needle roller thrust bearing makes it relatively compact in the radial structure. Although it has a small cross-section, it can still bear a high load. The outer diameter of this bearing is the smallest, and it is particularly suitable for support structures with limited radial installation dimensions.

[0003] When installing a plain bearing, the needle rollers need to be pressed into the cage, and the pressing depth needs to be effectively controlled. When the existing needle rollers are installed, the cage cannot be effectively fixed, and the automatic adjustment of the pressing position cannot be carried out after positioning, resulting in inconvenient installation of the needle rollers. Since the plain bearing has a flat structure, it is difficult to take out the needle rollers from the interior of the assembly equipment after installation. Summary of the Utility Model

[0004] The utility model aims at the defects in the prior art and provides an assembly tooling for a self-locking plain bearing.

[0005] The utility model is realized by the following technical solutions:

[0022] As Figures 1-5 shown, an assembly tooling for a self-locking plain bearing includes a base 1, a mounting ring 2, a clamping seat 3, a wedge block 4, an ejecting mechanism 5, a control mechanism 6, a clamping mechanism 7 and a gear 8. The mounting ring 2 is fixedly arranged on the upper surface of the base 1. The clamping seat 3 is movably connected to the inner side of the mounting ring 2. The wedge block 4 is fixedly arranged on the top of the clamping seat 3. The ejecting mechanism 5 is arranged inside the clamping seat 3. The control mechanism 6 is arranged on the upper surface of the base 1. The clamping mechanism 7 is arranged on the inner side of the top of the clamping seat 3. The gear 8 is fixedly arranged outside the clamping seat 3. The ejecting mechanism 5 includes a lifting plate 51, an ejecting rod 52, a first spring 53 and a hand ring 54. The ejecting rod 52 is fixedly arranged on the upper surface of the lifting plate 51. The first spring 53 is sleeved outside the ejecting rod 52. The hand ring 54 is fixedly arranged outside the lifting plate 51. The clamping mechanism 7 includes a cylinder 71, a lifting plate 72, a guide rod 73, a second spring 74 and a pressing strip 75. An installation hole is opened at the top of the clamping seat 3. The cylinder 71 is installed in the installation hole at the top of the clamping seat 3. The lifting plate 72 is fixed to the end of the cylinder 71. An installation groove is opened on the outer side of the lifting plate 72. A guide rod 73 is fixedly arranged at the bottom of the installation groove. The second spring 74 is sleeved on the surface of the guide rod 73. The pressing strip 75 is clamped in the installation groove on the side surface of the lifting plate 72.

[0023] Specifically, the control mechanism 6 includes an electric telescopic rod 61 and a rack 62. The electric telescopic rod 61 is installed on the upper surface of the base 1, and the rack 62 is fixedly arranged at the telescopic end of the electric telescopic rod 61. The rack 62 meshes with the gear 8. The lifting plate 51 is clamped inside the clamping seat 3. The first spring 53 is located between the lifting plate 51 and the inner side of the top of the clamping seat 3. A clamping hole for the ejector rod 52 to cooperate with is opened at the top of the clamping seat 3. The top of the ejector rod 52 is lower than the top of the clamping hole at the top of the clamping seat 3. A clamping groove for cooperating with the plane bearing cage is opened at the top of the clamping seat 3. A groove for cooperating with the depth of the needle roller clamping is opened at the bottom of the clamping groove at the top of the clamping seat 3. A contact block for cooperating with the wedge block 4 is arranged at the bottom of one end of the pressing strip 75. One end of the guiding rod 73 extends into one end of the pressing strip 75. The second spring 74 is arranged inside the pressing strip 75.

[0024] In this embodiment, first, ensure that the electric telescopic rod 61 is in a fully retracted state. Then, the cage is clamped into the clamping groove at the top of the clamping seat 3 that cooperates with it, and the installation angle of the cage is adjusted according to the pressing and installation position of the needle roller. Then, control the cylinder 71 to contract. As the cylinder 71 contracts, the lifting plate 72 descends. The inclined position of the lower surface of the contact block at the bottom of the pressing strip 75 contacts the top inclined surface of the wedge block 4. As the cylinder 71 contracts, the pressing strip 75 is pushed out under the guidance of the guiding rod 73, and the second spring 74 is compressed and contracted. The protruding part at the bottom of the front end of the pressing strip 75 presses on the upper surface edge of the cage, achieving the effect of fixing the cage.

[0025] Furthermore, the pressing device presses the needle roller into the mounting hole on the surface of the cage. The pressing depth is controlled by the depth of the groove at the bottom of the mounting clamping groove on the upper surface of the clamping seat 3. After the installation of a single needle roller is completed, the electric telescopic rod 61 extends a certain distance, so that the rack 62 moves a certain distance, thereby driving the gear 8 to rotate a certain angle, achieving the effect of switching the needle roller installation area. A support guiding strip is arranged on the upper surface of the base 1 and clamped at the bottom of the rack 62 to achieve the effect of guiding and limiting. When all the needle rollers are installed, the cylinder 71 extends. Under the action of the second spring 74, the pressing strip 75 automatically contracts, releasing the fixing effect on the cage. At this time, lift the hand ring 54, the lifting plate 51 rises, and the ejector rod 52 ejects the finished product, facilitating the material taking work. The first spring 53 facilitates the automatic reset of the lifting plate 51.
