Abstract
The utility model discloses the supporting sleeve in a kind of two rotating shaft piece bearing devices.This supporting sleeve is arranged on welding machine cross slide seat, and comprise the upper axle journal of coaxial setting up and down and lower axle journal, the center of upper axle journal and lower axle journal is respectively equipped with upper shaft hole and lower shaft hole, forms the shaft shoulder at the jointing place radial protrusion of upper axle journal and lower axle journal.The utility model structure is simple, is realized the rotation of the rotation drive welding gun of horizontal slide in automatic welding machine, simplify two rotor supporting structures by supporting sleeve.
Description
technical field:
The utility model relates to the supporting sleeve in a kind of two rotating shaft piece bearing devices.
background technique:
Cross slide seat in automatic welding machine drives welding gun motion, and horizontal slide wherein drives welding gun to move horizontally and around the rotation of horizontal axis, wherein, in horizontal slide, leading screw drives welding-torch horizontal to move by rotating, the rotation of welding gun is then driven by horizontal stand, and lead screw shaft and horizontal stand are the rotors of two coaxial lines, if design by usual shaft support design, its supporting structure will be comparatively complicated, thus make whole cross slide seat volume large, cost is high, is not easy to handling and the maintenance of automatic welding machine simultaneously.
summary of the invention:
The utility model provides the supporting sleeve in a kind of two rotating shaft piece bearing devices to solve above-mentioned prior art Problems existing.
The technological scheme that the utility model adopts has:
Supporting sleeve in two rotating shaft piece bearing devices, described supporting sleeve is arranged on welding machine cross slide seat, comprise the upper axle journal of coaxial setting and lower axle journal, the center of described upper axle journal and lower axle journal is respectively equipped with upper shaft hole and lower shaft hole, forms the shaft shoulder at the jointing place radial protrusion of upper axle journal and lower axle journal.
Further, the circumferential surface of described upper shaft hole is provided with the step surface for bearing location.
Further, described lower shaft hole circumferential surface is provided with keyway.
Further, described lower axle journal end axis is provided with annular brace locating slot to a position.
Further, the described shaft shoulder is provided with attachment hole.
Further, described upper shaft hole and lower shaft hole connect.
The utility model structure is simple, is realized the rotation of the rotation drive welding gun of horizontal slide in automatic welding machine, simplify two rotor supporting structures by supporting sleeve; The axle journal of axle sleeve is provided with the shaft shoulder of this axle sleeve of convenient assembling and disassembling, makes the connection of axle sleeve more reliable; Axle journal is provided with the annular brace locating slot of positioning bearing, avoids generation dislocation when bearing is fixed on axle sleeve axle journal mobile, decrease axle sleeve wearing and tearing, add the working life of this axle sleeve; Be provided with keyway at axis hole, convenience is connected with motor output shaft.
accompanying drawing illustrates:
Fig. 1 is the structural drawing of the utility model axle sleeve.
Fig. 2 is described axle sleeve sectional structure chart.
Fig. 3 is described axle sleeve structural representation on horizontal slide.
