Numerically-controlled electrical riveting machine for riveting of extra-large bearing retainer supporting columns

Abstract

The invention discloses a numerically-controlled electrical riveting machine for riveting of extra-large bearing retainer supporting columns. The numerically-controlled electrical riveting machine comprises a hydraulic positioning and electrical riveting component, a rotating workbench component, a heating system, a cooling system and a numerical control system. The numerically-controlled electrical riveting machine for riveting of the extra-large bearing retainer supporting columns adopts the numerical control system for controlling, a workbench is driven to move longitudinal and rotationallyalong a machine body by a step motor a and a step motor b to realize workpiece moving and rotation indexing numerical control, and single-end heating and single-end riveting are realized; an electricheating head and a riveting head are in bilateral arrangement; an efficient and stable operating state of the numerically-controlled electrical riveting machine is guaranteed by measures such as vertical position adjustment of a hollow cyclic cooling structure and a hydraulic cylinder in the electric heating head. The numerically-controlled electrical riveting machine has advantages of high automation degree, stability in machining quality, high production efficiency, low consumption and energy saving. In addition, labor intensity of operating personnel is effectively relieved, and integral quality of bearing products is improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing machine manufacturing, and relates to a numerically controlled electric riveting machine for riveting the pillar of an extra-large bearing cage. Background technique [0002] At present, the riveting process of extra-large bearing pillar type cage mainly adopts low-voltage, high-current electrode heating and manual adjustment for heating and riveting. The processing method is to move the pressure rod by hand to press down the electric heating head, and manually check the temperature of the rivet to control the temperature. When it can be riveted, the electric heating head will be riveted down by the riveting head to rivet the rivet of the bearing cage. After the riveting is completed, Manually reset the electric heating head upwards, and then manually adjust the cage to carry out the riveting of the next rivet. In this process, since there is no automatic rotation and positioning device for t...

AI Technical Summary

Problems solved by technology

In this process, since there is no automatic rotation and positioning device for the cage on the working table of this type of cage riveting equipment, the position of the cage must be adjusted every time riveting, and the rivet is aligned with the riveting head for riveting.

In addition, during the riveting process, the electric heating head is in contact with the pillar of the cage, resulting in a low-voltage and high-current electrode heating method. If the current is too large, it often causes electric damage to the cage and rollers, affecting the quality of the bearing product, seriously lead to product scrapping

Secondly, the equipment is heated at both ends at the same time, and the oil cylinder is riveted, which will easily lead to bending and deformation of the bearing pillar and affect the quality of the bearing product

[0003] This processing method is greatly affected by the technical level of the operator, and there are factors such as unstable product quality, high energy consumption, high labor intensity, low production efficiency, and high production cost, which is not conducive to the market competition of bearing products.
