During this rotation process, only the position of the maximum outer diameter of the joint bearing will be subjected to extrusion by the inner circumferential wall of the bearing hole, and the extrusion does not occur simultaneously but gradually occurs during the rotation of the joint bearing around the X-axis direction. Therefore, the stress area of the joint bearing subjected to extrusion is far smaller than that of the joint bearing directly pressed downwards into the bearing hole in the coaxial direction, so that surface damage and internal damage of the joint bearing during pressing can be greatly avoided, and the performance and stability of the product can be ensured.

The positioning table 112 can slide up and down relative to the base 111 in the Z-axis direction. Preferably, a guide column extending in the Z-axis direction is arranged between the base 111 and the positioning table 112, and the positioning table 112 is slidingly matched with the guide column. The upper end of the positioning table 112 is provided with a positioning groove 112a, and the shape of the positioning groove 112a matches the shape of the end of the workpiece 70. During assembly, the end of the workpiece 70 is arranged in the positioning groove 112a, so as to limit the displacement of the workpiece 70 in the horizontal direction, and realize the positioning of the workpiece 70.

When the workpiece 70 needs to be pressed, the pressing rod 117 is rotated to the upper side of the workpiece 70 and then pressed down. When the workpiece 70 needs to be removed after assembly is completed, the pressing rod 117 is moved upward to loosen the workpiece 70 and is rotated to make room, so as to facilitate other mechanical structures to remove the workpiece 70. In some preferred modes, the lower surface of the pressing rod 117 is provided with a flexible pad, and the pressing rod 117 contacts the upper surface of the workpiece 70 through the flexible pad, so as to avoid bruising the workpiece 70.

[0087] As shown in the figure, Figure 12 The embodiment one also discloses an assembling method of a joint bearing, which uses the above-mentioned assembling device 10, and the assembling method includes the following steps:

[0088] Step A100, an external mechanical hand places a workpiece 70 on the positioning assembly 110, specifically: the external mechanical hand places the workpiece 70 on the positioning table 112, the end of the workpiece 70 is arranged in the positioning groove 112a of the positioning table 112, and the pressing rod 117 rotates and presses the workpiece 70;

[0089] Step A200, the bearing connecting part 1241 of the mounting arm 124 is connected with the joint bearing 60 to be assembled, the outer circumferential surface of the joint bearing 60 is aligned with the outer expansion arc groove 70b of the bearing hole 70a in the Z-axis direction, specifically: the bearing connecting part 1241 moves downward and is connected with the joint bearing 60 to be assembled, the joint bearing 60 to be assembled corresponds to the bearing hole 70a of the workpiece 70 up and down, and since the joint bearing 60 is vertical (that is, the axial direction of the joint bearing 60 is the X-axis direction) when the mounting arm 124 takes the material, the joint bearing 60 is aligned with the outer expansion arc groove 70b of the bearing hole 70a in the Z-axis direction;

[0090] Step A300, the mounting arm 124 drives the joint bearing 60 to move downward along the Z-axis direction until the joint bearing 60 is assembled into the bearing hole 70a and the outer expansion arc groove 70b, specifically: the first Z-axis module 123 drives the mounting arm 124 and the joint bearing 60 to be assembled to be inserted downward into the bearing hole 70a, and stops when inserted to a predetermined depth, generally, when the axis of the joint bearing 60 reaches 1 / 2 of the depth of the bearing hole 70a, the mounting arm 124 stops moving downward; wherein, due to the design of the outer expansion arc groove 70b, the joint bearing 60 will not be subjected to extrusion force during the process of being inserted vertically downward into the bearing hole 70a;

[0091] Step A400, the first rotary driving part 125 drives the mounting arm 124 and the joint bearing 60 to rotate ninety degrees in the bearing hole 70a around the Z-axis direction, specifically: the joint bearing 60 rotates ninety degrees around the axis of the bearing hole 70a (that is, the Z-axis direction), and after the rotation is completed, the mounting arm 124 is reset upward, and the outer circumferential surface of the joint bearing 60 will not be subjected to extrusion during the process of self-rotation of the joint bearing 60 around the Z-axis direction;

[0092] Step A500, the first X-axis module 131 drives the first clamping jaw 134 to move along the X-axis direction and approach the workpiece 70 until the first clamping jaw 134 moves to the outer circumferential side of the joint bearing 60 and clamps the outer circumferential side of the joint bearing 60, specifically: after the joint bearing 60 rotates ninety degrees around the Z-axis direction, the first X-axis module 131 of the second mounting assembly 130 drives the second sliding table 132, the second rotary driving part 133 and the first clamping jaw 134 to gradually approach the joint bearing 60 on the workpiece 70 along the X-axis direction until the first clamping jaw 134 is located on the outer side of the joint bearing 60, and then the first clamping jaw 134 clamps the outer circumferential surface of the joint bearing 60;

[0093] Step A600, the second rotary drive 133 drives the first jaw 134 and the joint bearing 60 to rotate 90 degrees around the X-axis direction. After installation, the first jaw 134 releases the joint bearing 60 and resets. Specifically: the second rotary drive 133 and the first jaw 134 drive the joint bearing 60 to rotate 90 degrees around the X-axis direction, so that the joint bearing 60 is in contact or clearance fit with the movable arc groove 70c in the bearing hole 70a, and the joint bearing 60 is coaxial with the bearing hole 70a, thereby completing the installation of the joint bearing 60. It should be noted that during the rotation of the joint bearing 60 around the X-axis direction, the area of the joint bearing 60 subjected to extrusion at the same time is limited, and the joint bearing 60 still has deformation space in its radial direction, which can release stress and avoid damage.

[0094] The first mounting assembly 120 drives the joint bearing 60 to insert into the bearing hole 70a along the Z-axis direction, and then the first mounting assembly 120 drives the joint bearing 60 to rotate 90 degrees around the Z-axis. Then, the second mounting assembly 130 drives the joint bearing 60 to rotate 90 degrees around the X-axis direction, and the installation is completed. In this embodiment, by using step-by-step spinning, the joint bearing 60 is first vertically pressed in, then rotated, and then rotated and leveled. The joint bearing 60 has deformation space throughout the process and the area subjected to extrusion at the same time is small, which can greatly avoid surface damage and internal damage of the joint bearing 60 during pressing, and ensure the performance and stability of the product.
