The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Referring to fig. 1 and 2, fig. 1 shows a top view of a mounting assembly of an embodiment of the present invention, and fig. 2 shows a cross-sectional view of fig. 1. As shown in the drawings, the assembling device of the present embodiment for assembling a flexible bearing and a cam of a wave generator includes: the device comprises a bottom plate 1, a guide rail 2, screws 3, a power device, a jig pressing block, a limiting block 6 and a pressing rod 7. In this embodiment, the power unit is a cylinder assembly, in other embodiments, other types of power units are possible, and the power unit is not limited to a cylinder.
It should be understood that the base plate 1 is provided with a guide rail 2, and the guide rail 2 is fixed on the base plate 1 by a screw 3. The left end of the bottom plate 1 is provided with an air cylinder assembly, and the air cylinder assembly comprises an air cylinder 41, an air cylinder piston rod 42 and an air cylinder push block 43; wherein a part of the cylinder piston rod 42 is arranged in the cylinder 41, and the front end of the cylinder piston rod 42 is fixedly provided with a cylinder push block 43. When the cylinder 41 is started, the cylinder piston rod 42 is movably extended from the cylinder 41, and drives the cylinder push block 43 arranged at the front end of the cylinder piston rod to move towards the direction of the first press block 51.
A jig pressing block is arranged on the guide rail 2 and comprises a first pressing block 51 and a second pressing block 52, and the first pressing block 51 and the second pressing block 52 are of split structures and can be separated from each other; in this embodiment, the first pressing piece 51 is on the left, and the second pressing piece 52 is on the right. Both the first and second pressing pieces 51, 52 are provided with grooves, which may be semi-elliptical grooves, for example, and each of the grooves can accommodate a portion of the flexible bearing. The cylinder piston rod 42 can drive the first pressing block 51 to move towards the second pressing block 52, when the first pressing block 51 is jointed with the second pressing block 52, a limiting groove is defined on the jig pressing block, and the limiting groove can accommodate the deformed flexible bearing, for example, an oval groove, so as to guide the deformation of the flexible bearing 9.
In some embodiments of the present invention, the assembly component further includes a limiting block 6, the limiting block 6 is disposed at the rightmost end of the bottom plate 1 and connected to the rightmost end of the second pressing block 52, so that the maximum displacement of the second pressing block 52 can be limited; the assembly component also comprises a pressure lever 7 which is arranged above the jig pressing block and is matched with the jig pressing block for use.
When using the assembly, the cam 8 is frozen in a low temperature environment (e.g., -20 to-40 ℃) for 6 to 8 hours, so that the cam 8 is sufficiently shrunk. The inner ring of the flexible bearing 9 is limited to a shape similar to the outer ring of the cam, and one method for limiting the shape of the flexible bearing 9 is realized by using the assembly component disclosed in the above embodiment, for example, the flexible bearing 9 is placed in the groove of the second pressing block 52, so that the outer ring of the flexible bearing 9 abuts against the inner wall of the groove. Then, the air cylinder 41 is started, so that the air cylinder 41 pushes the first pressing block 51 to move towards the direction of the second pressing block 52 until the first pressing block 51 contacts with the flexible bearing 9. The cylinder 41 continues to push and press the first pressing block 51 towards the second pressing block 52 until the first pressing block 51 is jointed with the second pressing block 52, the jig pressing block is closed, and a limiting groove formed after the jig pressing block is closed is oval, so that the flexible bearing 9 generates oval deformation under the pressing action of the pressed and closed jig pressing block. It will be appreciated that the freezing step of the cam 8 is not preceded by the deformation step of the flexible bearing 9.
Secondly, adjusting the position and the posture of the cam 8 to enable the cam 8 to be positioned right above the limiting groove, enabling the long shaft of the cam 8 to be overlapped with the long shaft of the limiting groove, then placing the frozen cam 8 into the inner ring of the deformed flexible bearing 9, and arranging the cam 8 into the flexible bearing 9 by a method which is realized by utilizing the assembly disclosed by the embodiment, for example, sleeving the cam 8 which is fully frozen and contracted on the shaft of the pressure lever 7; subsequently, the pressing rod 7 is pressed down, and the cam 8 sleeved on the shaft of the pressing rod 7 is pressed into the inner ring of the flexible bearing 9 which is deformed in an elliptic manner. In the assembling process, the size of the cam 8 is smaller than that of the deformed inner ring of the flexible bearing 9 after being frozen, so that the cam 8 and the flexible bearing 9 are not in interference fit in the installation process of pressing the pressing rod 7 downwards, the contact between the cam 8 and the flexible bearing 9 can be reduced, and the damage of the assembling action on the cam 8 and the flexible bearing 9 is reduced.
Thirdly, placing the assembled cam 8 and the flexible bearing 9 at room temperature for standing or drying by using an air duct; and after the frost and water condensed on the wave generator are melted and evaporated to be dry, the assembly work of the wave generator is completed. When the assembly is performed by using the assembly components disclosed in the above embodiments, the cylinder 41 is started to return the first press block 51, and the wave generator is taken out from the jig press block, and then the wave generator is left to stand at room temperature or dried by using an air duct.
The cam and the flexible bearing are assembled according to the assembly component, so that the damage to the outer wall of the cam and the inner wall of the flexible bearing can be reduced, and the manufactured wave generator and the harmonic reducer have high precision and high durability.
The embodiments of the present invention have been described in detail, but the present invention is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are included in the scope of the present invention defined by the claims. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
