Bearing unit assembling method and assembling equipment

Abstract

The invention relates to the technical field of bearings, in particular to a bearing unit assembling method and assembling equipment. The method comprises the following steps of square bearing block feeding, square bearing block direction adjusting, square bearing block correcting, bearing feeding, square bearing block assembling, bearing unit discharging and bearing unit rotary plate conveying. According to the method, by arranging a bearing block rotating mechanism, the manual feeding time is shortened, rapid feeding is achieved, by arranging a bearing block correcting mechanism, the position deviation of a clamping fixture relative to a square bearing block positioning jig is avoided, the falling accuracy of a square bearing block is guaranteed, by arranging a discharging device, the square bearing block is accurately pushed into a shifting platform sliding groove for discharging, by arranging a rotary plate conveying device, the conveying time of the square bearing block is shortened, deviation of a bearing unit is avoided, and conveying stability of the bearing unit is guaranteed.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing unit assembly method and assembly equipment. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The bearing unit includes a square bearing seat and a cylindrical bearing. The cylindrical bearing is fitted in the bearing hole of the square bearing seat, and the outer ring of the cylindrical bearing and the bearing hole of the square bearing seat are interference fit; during the assembly of the bearing unit : 1) Transport the cylindrical bearing to the bearing hole of the square bearing seat; 2) Press the cylindrical bearing by the press-fitting device to press the bearing outer ring into the bearing hole of the square bearing seat for interference fit; 3) Put the press-fitted...

AI Technical Summary

Problems solved by technology

[0003] The existing technology has the following deficiencies: 1. When moving the square bearing seat, in order to ensure that the oil nozzle on the square bearing seat is transported in the correct direction, the square bearing seat is manually placed in the correct direction, and then the square bearing is moved by the moving mechanism. The seat is moved to the next station; while manually adjusting the direction of the square bearing seat, it is necessary to identify the correctness of the loading each time, and then put the square bearing seat into the feeding device, which increases the time for manual loading and is not conducive to fast loading

2. When the moving device moves the square bearing seat to the positioning fixture, the clamping fixture in the moving device first moves the square bearing seat above the correction positioning fixture, and then the clamping fixture drives the square bearing seat to drop directly to the correction positioning fixture In the tool; while the clamping fixture is driven by the cylinder guide rod, there will be a gap between the guide rod and the guide sleeve due to the wear of the guide rod after the cylinder guide rod has been used for a period of time, so that the guide rod moves relative to the guide sleeve in the gap. Shaking; when the guide rod drives the clamping fixture to fall, it will cause the position of the clamping fixture to shift relative to the positioning fixture of the square bearing seat, thus affecting the accuracy of the falling of the square bearing seat

3. When unloading the square bearing seat, the unloading and pushing mechanism first drives the upper top plane to lift the square bearing seat upwards, and then toggles the drive assembly to drive the protruding toggle block to push the side of the square bearing seat to lift the square bearing seat Push it into the chute of the toggle platform in the unloading toggle platform; while the upper top plane is a plane, and the upper top plane has no guiding effect on the moving direction of the square bearing seat; and the toggle block extends a long distance from the toggle drive assembly, The toggle block and the toggle drive assembly are cantilever structures; the small movement error on the toggle drive assembly will be amplified according to the principle of leverage after being transmitted by the cantilever structure, so that the moving direction of the toggle block is relatively offset from the set direction. Large, the square bearing seat cannot be accurately pushed into the chute of the toggle platform for discharging

4. When conveying the bearing unit, use the linear moving device to drive the air gripper to grab the bearing unit and move it from the blanking station to the receiving device; while the linear moving device needs to move the captured bearing unit to the receiving device first , and then the linear transfer device returns to the blanking station to move the next bearing unit, so that the bearing unit needs to wait for the two processes of moving and returning of the linear transfer device, which increases the conveying time of the bearing unit; and the linear transfer device grabs The bearing unit is directly grasped by the air gripper, and the air gripper only positions the two opposite sides that the air gripper touches, that is, only positions the bearing unit in one direction; when it is impacted during the moving process Or when vibrating, the bearing unit is easy to deviate in the vertical direction relative to the grabbing direction of the air gripper, thus affecting the stability of the bearing unit conveying
