Technical Field

The invention relates to bearing roll package assembly, in particular to parabolic joint bearing roll package assembly equipment.

Background

Spherical plain bearings are standard parts used in the mechanical and aeronautical industries in a very wide range of applications. The universal assembly modes of the parts comprise roll-pack assembly and stamping assembly. Although the rolling strength quality can be ensured in the traditional three-ball rolling mode, the operation is inconvenient, the rolling efficiency is relatively low, three balls with different sizes roll along the raceway, and the pressing tracks on the raceway are difficult to ensure consistency, namely the contact ratio of the raceway circle is insufficient, the problem of wrinkles and skin on the surface of the raceway is difficult to avoid, and the service life of the tool is relatively short. The stamping and edge covering assembly mode has the advantages that the assembly force is large, the risk of extrusion deformation of workpieces and bearings is large, and the service life of a stamping tool is short.

Disclosure of Invention

The invention aims to solve the problems of high power consumption, poor quality and low rolling efficiency of assembling equipment of a joint bearing in the prior art, and provides parabolic joint bearing rolling assembling equipment.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

the invention relates to a parabola-shaped joint bearing rolling and packaging assembly device which is characterized in that: comprises a constant pressure rod, a roller shaft, a rolling wheel and a workpiece clamp;

the lower end of the constant pressure rod is provided with a U-shaped notch with a downward opening, and the inner walls of two sides of the U-shaped notch are provided with mounting holes;

two ends of the roller shaft are respectively arranged in the two mounting holes;

the rolling wheel is sleeved on the roller shaft and protrudes outwards from the U-shaped notch, a bulge is outwards arranged on the outer peripheral surface of the rolling wheel, and the section of the bulge is in a parabolic shape;

the rolling wheel is characterized in that a workpiece clamp is arranged below the rolling wheel, a counter bore used for installing a bearing seat to be machined is formed in the workpiece clamp, and the workpiece clamp clamps the bearing seat to be machined to rotate around the axis of the bearing seat to be machined.

Further, the press machine is connected with the constant pressure rod and used for providing constant pressure for the constant pressure rod.

Further, the workpiece clamping device further comprises a motor which is connected with the workpiece clamping device and used for providing rotary power for the workpiece clamping device.

Furthermore, the counter bore is a step bore, a large hole of the counter bore is matched with the bearing seat to be processed, and a small hole of the counter bore is matched with the inner ring of the joint bearing.

Furthermore, the rolling wheels and the protrusions are of an integral structure and are all made of hard alloy.

Further, the hardness of the protrusion is HRC60 or more.

Further, the formula of the section parabola of the bulge is that y is 0.5x²Wherein x is the axial direction of the rolling wheel, and y is the radial direction of the rolling wheel.

The invention has the beneficial effects that:

the invention transmits the constant acting force on the constant pressure rod to the bulge by arranging the bulge with the parabolic section on the peripheral surface of the rolling wheel, so that the bulge generates the axial constant pressure, is contacted with the annular V-shaped groove on the bearing seat to be processed and deforms the bearing seat, the area is the minimum and the pressure is the maximum when the bulge with the parabolic section is contacted with the annular V-shaped groove, and the contact point is continuous and smooth; meanwhile, the workpiece clamp drives the bearing seat to be machined to rotate, and the rolling assembly of the joint shaft and the bearing seat is completed through the downward pressing of the bulge and the rotation of the workpiece clamp, so that the assembly power consumption is low; the surface of the rolled raceway is smooth, the surface quality is ensured, and the rolling efficiency is relatively high.
