Description

  The present invention relates to a component fixing device, and more particularly, to a component fixing device that fixes a conveying jig and a housing.

  Conventionally, reusable screws or non-reusable rivets have been used as an example of an instrument for fixing hardware. FIG. 12 is a side view of an example of a conventional component fixing device and attachment component.

  Referring to the figure, tools 101 and 102, screws 103, washers 104, nuts 105, and attachment parts 106 and 107 are displayed.

  That is, conventionally, the screw 103, the washer 104, and the nut 105 are used to fix the attachment parts 106 and 107. Then, the nut 105 is supported by the tool 102 and the mounting parts 106 and 107 are fixed by turning the screw 103 with the tool 101. Alternatively, the mounting parts 106 and 107 are fixed by supporting the screw 103 with the tool 101 and turning the nut 105 with the tool 102.

  However, it is necessary to use a tool for fixing the conventional mounting parts, and therefore, there is a disadvantage that a lot of time is spent and the burden on the operator is large.

  On the other hand, an example of means for solving this drawback is disclosed in Patent Document 1. This is because the device surface is formed on the outer periphery of the washer, and a spring that presses the washer in the tightening direction is provided between the washer and the nut. A step portion for locking the washer is provided at the position.

  According to this technology, with a washer and nut attached to a tightening bolt, the support base to which the bolt is attached is moved horizontally, and the bolt is attached to the object to be secured without using a tool. The body can be fixed.
