It should be noted that: the drawings are in simplified form and are not to precise scale, the intention being solely for the convenience and clarity of illustrating embodiments of the invention; second, the structures shown in the drawings are often part of actual structures.
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Example (b):
referring to fig. 1 and 2, the rolling and assembling device for the parabolic spherical plain bearing of the present embodiment includes a constant pressure rod 1, a roller shaft 2, a rolling wheel 3, a work holder 4, a press, and a motor;
the lower end of the constant pressure rod 1 is provided with a U-shaped notch 11 with a downward opening, and the inner walls of two sides of the U-shaped notch 11 are provided with mounting holes 12; two ends of the roller shaft 2 are respectively arranged in the two mounting holes 12; the rolling wheel 3 is sleeved on the roller shaft 2, the rolling wheel 3 protrudes outwards from the U-shaped notch 11, a bulge 31 is outwards arranged on the outer peripheral surface of the rolling wheel 3, and the section of the bulge 31 is in a parabola shape; the rolling wheel 3 and the bulge 31 are of an integral structure, are made of hard alloy, and have the hardness of more than or equal to HRC 60. A workpiece clamp 4 is arranged below the rolling wheel 3, a counter bore 41 used for installing a bearing seat 5 to be machined is arranged on the workpiece clamp 4, the counter bore 41 is a stepped bore, a small bore 412 of the stepped bore is positioned at the lower end of a large bore 411, the large bore 411 is matched with the outer circular surface of the bearing seat 5 to be machined, and the small bore 412 is matched with an inner ring 62 of the joint bearing 6. The work holder 4 holds the bearing housing 5 to be machined to rotate around the axis thereof. The press is connected to the constant pressure bar 1 for supplying a constant pressure to the constant pressure bar 1. The motor is connected with the work holder 4 and is used for providing rotary power for the work holder 4.
Therefore, a vertical downward force is given to the constant pressure rod 1 by a press machine or manpower, the constant pressure rod 1 transmits the force to the bulge 31 and the annular V-shaped groove 51 on the bearing seat 5 to be processed in sequence, the parabolic curved surface on the bulge 31 is contacted with the annular V-shaped groove 51 to deform the same, the parabolic curved surface can ensure the minimum area and the maximum pressure when the rolling wheel 3 is contacted with the annular V-shaped groove 51, and the contact surface is kept continuous and smooth, the tool clamp 4 drives the bearing seat 5 to be processed to rotate, the annular V-shaped groove 51 is gradually contacted with the parabolic curved surface on the protrusion 31 rolling by autorotation, because the hardness of the bearing seat 5 to be processed is far lower than the hardness of the material of the rolling wheel 3, the annular V-shaped groove 51 is rolled into a parabolic curved groove, and the annular V-shaped groove 51 is extruded and flanged to wrap the edge of the bearing outer ring 61, so that the assembly rolling package of the bearing is completed.
The rotating speed, the number of machining circles and the pressure of the constant pressure rod 1 in the machining process of the workpiece clamp 4 are all required to be optimized and trial-assembled according to different sizes of the knuckle bearings during rolling. The parameters after trial fitting will become the fixed preferred fitting parameters for fitting the specification size spherical plain bearing. For example: the bearing seat to be processed is made of 316 stainless steel, and the joint bearing is UC 12. The parameters of the matching are as follows: the diameter of the outer edge of the rolling wheel 3 is 11mm, the thickness is 6mm, and the parabola formula is that y is 0.5x2Wherein x and y take the contact point of the bulge 31 and the bearing seat 5 to be processed as a circular point, the radial direction of the rolling wheel 3 as a y axis, and the radial direction of the bearing seat 5 to be processed as an x axis. The constant pressure is 300KG, the fixture rotating speed is 5r/mi n, the number of rolling turns is 1 circle, and the part after rolling passes through standard test, reaches qualified standard.
The parabolic spherical plain bearing roll-pack assembling equipment provided by the embodiment has the working principle as follows:
according to the preferred principle of the rolling line, on one hand, the vertical pressure is required to be small, on the other hand, the rotating moment is required to be minimum, the area of the extrusion contact point of the rolling line and the bearing seat 5 to be processed is small enough, and the enough extrusion pressure can be ensured, so that the power consumption of the plastic deformation of the bearing seat 5 to be processed is relatively minimum by the rolling mode. Therefore, the pressing line with the minimum power consumption should be the moving track of the contact point with the maximum pressing component generated by the minimum force applied to the contact point on the moving direction projection. As shown in fig. 3, on the vertical force-bearing surface, the protrusions 31 on the rolling wheel 3 are pressed from top to bottom along the axial direction thereof, the projection of the trajectory is divided into a composite trajectory of the moving speed of the contact point moving radially outward along the bearing seat 5 to be machined and the moving speed of the contact point moving downward along the vertical direction, and according to the variation of the moving speeds of the two, the trajectory forms a parabolic shape as shown in fig. 4.
As shown in fig. 5, in the case that the bearing seat to be machined is rotationally moved along its circumferential direction on the horizontal plane, and the rolling wheel 3 is relatively kept stationary, and in the case that the contact point area between the protrusion 31 and the annular V-shaped groove 51 on the bearing seat 5 to be machined is the smallest, the movement locus is the resultant speed locus of the radial movement speed and the tangential movement speed along the rotation circumference, as shown in fig. 6, which is also a parabolic locus.
The optimal moving tracks of the two surfaces of the horizontal surface and the vertical surface are all in the form of parabolas in the same direction, so that the compression curved surface of the entity rolling wheel can be synthesized from the projection tracks of the two vertical surfaces, and the curved surface becomes the optimal compression curved surface according to the principle of preference. This is the greatest finding of the invention on the principle of extrusion.
Because the parabola is a smooth curve, a contact point forms a rotating curved surface around a point all the time in the rolling process, the surface of the rolled raceway is smooth, and heavy skin and wrinkles cannot be generated.
The parabola extrusion principle is used for bearing rolling package assembly, and the consumed power is low, so that the processing is labor-saving and time-saving, the maximum rolling effect is exerted by the minimum force, and the assembly efficiency and the assembly quality of workpieces can be improved. The effect of four or two stirring jacks is achieved, and the effect of twice the result is achieved with half the effort.
