Definitions

  • the present invention relates to a washer bending device for bending a washer to stop the rotation of a screw-attaching work screw-attached to a screw-attaching portion through the washer.
  • the rotation of the screw-attaching work is formerly stopped to prevent loosening of a screwing state to the screw-attaching portion and detachment from the screw-attaching portion with respect to the screw-attaching work such as a bolt or the like screw-attached to the screw-attaching portion through the washer.
  • the screw-attaching work such as a bolt or the like screw-attached to the screw-attaching portion through the washer.
  • an engaging pawl for engagement with an engaging portion or the like of the screw-attaching portion in advance is first arranged in the washer, and the rotation of the screw-attaching work is stopped with respect to the screw-attaching portion.
  • one portion of the washer nipped between the screw-attaching portion and the screw-attaching work is bent along a flat portion located in a hexagonal head portion of the bolt or the like.
  • the rotation of the washer is stopped with respect to the screw-attaching portion, and the rotation of the screw-attaching work is bent along a flat portion located in a hexagonal head portion of the bolt or the like.
  • the rotation of the washer is stopped with respect to the screw-attaching portion, and the rotation of the screw-attaching work such as the bolt or the like is stopped by the bent one portion of the washer, and a screw-attaching state of the screw-attaching work to the screw-attaching portion is maintained.
  • a socket member is provided at one end with a recess adapted to receive a bolt head or nut, and an actuating member is shiftabily mounted at one side thereof and provided at its lower portion with a wedge portion adapted to be inserted between the locking portion of a lock washer and said bolt head or nut.
  • U.S. Patent No. 2,950,944 discloses a bearing retaining assembly for locking a bearing on an axle having a threaded end and a keyway comprising a washer having a key engageable in the keyway, an annular flocking element disposed adjacent to the washer, the locking element and the washer having cooperatively interengaged means for presenting rotation of said flocking element relative to the washer.
  • the present invention dissolves such disadvantages and its object is to provide a washer bending device able to continuously make the confirming operation of the fastening degree of the screw-attaching work screw-attached to the screw-attaching portion through the washer and the bending operation of the washer for stopping the rotation of the screw-attaching work for a short time, and improve working operation.
  • the present invention refers to a washer bending device in which a screw-attaching work having a screw portion, and a projecting-out portion projected out and formed at a base end of the screw portion and having a flat face at its outer circumference, the screw-attaching work can be screw-attached to a screw-attaching portion through a washer nipped between the projecting-out portion of the screw-attaching work and a screw-attaching portion, said washer having a shape projected out in a flange shape; and, from a state in which rotation of the washer is stopped as a result of one portion of an outer circumference of the washer being engaged with an engaging portion arranged at the screw-attaching portion, another portion of the outer circumference of the washer can be bent by the washer bending device along the flat face of the projecting-out portion so that the rotation of the screw-attaching work with respect to the screw-attaching portion is stopped through the washer; characterized in that the washer bending device comprises: a work storing member of a
  • the washer bending device of the present invention is used with respect to the screw-attaching work screw-attached to the screw-attaching portion.
  • the screw portion of the screw-attaching work is screwed to the screw-attaching portion.
  • the projecting-out portion projected out of the base end of the screw portion is formed, and the flat face is formed in the outer circumference of the projecting-out portion.
  • a hexagonal portion seen from a plane such as the head of a bolt is used as this projecting-out portion.
  • the flat face of the projecting-out portion may have a shape able to fit a spanner, a wrench or the like when the screw portion is screwed to the screw-attaching portion.
  • the screw portion is screwed to the screw-attaching portion in a state inserted into the washer.
  • the screw-attaching portion and the projecting-out portion attain a state screw-attached through the washer.
  • the washer is located between the screw-attaching portion and the projecting-out portion, one portion of its outer circumference is engaged with the engaging portion arranged in the screw-attaching portion.
  • the washer bending device of the present invention is then used as follows.
  • a portion except for the screw portion of the screw-attaching work screw-attached to the screw-attaching portion is stored to the storing chamber from a side through the opening portion of the work storing member.
  • the projecting-out portion of the screw-attaching work stored in the storing chamber is fitted to the fitting portion.
  • the washer abutting portion of the washer bending member simultaneously abuts against the face of the screw-attaching portion side of a portion projected out in a flange shape from a portion between the screw-attaching portion of the washer and the projecting-out portion of the screw-attaching work.
  • the washer abutting portion abuts against the washer in a position corresponding to the flat face.
  • the handle of the support frame is rotated and operated and rotation torque is given to the screw-attaching work in a screwing direction to the screw-attaching portion.
  • the support frame supports the work storing member, and the projecting-out portion of the screw-attaching work is fitted to the fitting portion of the work storing member. Accordingly, the rotation torque can be easily given to the screw-attaching work through the work storing member by merely rotating and operating the handle. A fastening degree of the screw-attaching work to the screw-attaching portion can be confirmed by the handle operation at this time, and fastening is again performed if the screw-attaching work is loosened with respect to the screw-attaching portion.
  • the screw-attaching work is pressed toward the screw-attaching portion by the pressing device along its axial direction.
  • the support frame, the work storing member and the washer bending member are relatively integrally retreated with respect to the screw-attaching work screw-attached to the screw-attaching portion.
  • the washer abutting portion of the washer bending member is retreated while bending the projecting-out portion of the washer, and the projecting-out portion of the washer is bent along the flat face of the projecting-out portion of the screw-attaching work.
  • the rotation of the screw-attaching work is stopped with respect to the washer by the bent portion of the washer, and the rotation of the washer is stopped with respect to the screw-attaching portion by the engaging portion of the screw-attaching portion as mentioned above. Accordingly, screw loosening of the screw-attaching work with respect to the screw-attaching portion is prevented.
  • the washer bending device of the present invention just after the confirming operation of a fastening degree of the screw-attaching work screw-attached to the screw-attaching portion through the washer, the washer can be bent by merely operating the pressing device. Accordingly, the confirming operation of the fastening degree and the bending operation of the washer can be continuously made for a short time, and working operation can be improved.
  • the washer bending member is rotatably arranged along the outer circumference of the work storing member.
  • the washer bending member is rotated and the washer bending member is rotated and the arm portion of the washer bending member is aligned with a position corresponding to the opening portion so that dislocation of the screw-attaching work from the storing chamber can be reliably prevented.
  • the work storing member is supported by the support frame so as to be freely advanced and retreated with respect to the washer abutting portion of the washer bending member, and the support frame has a biasing device which biases the work storing member toward the washer abutting portion of the washer bending member.
  • the work storing member can be elastically retreated at a stage at which the washer is being bent by the washer abutting portion. Accordingly, the washer can be smoothly and precisely bent without unnecessarily deforming the washer.
