Abstract

PURPOSE:To suppress wear of a bearing and prolong the life of a device by furnishing a fixed shaft, which guides a traveling unit slidingly, and a bracket having a bearing to support the free end of said fixed shaft, and thereby eliminating fear of deformation of the fixed shaft despite its elongation/contraction owing to thermal expansion. CONSTITUTION:Two brackets 7a, 7b are fixed on a base 6, and a fixed shaft 8 is installed in such a way that its one end is supported by the bracket 7a as a cantilever. A bearing 9 is fixed in the bracket 7b to bear the free end of said fixed shaft 8. A traveling unit 10 has a movable unit bearing and slides on the fixed shaft 8 in the axial direction under guidance of this shaft 8. During continuous use, the fixed shaft 8 elongates toward the free end owing to thermal conduction from the motor mounted on the unit 10 are frictional heat at the sliding surfaces. At this time, the bearing 9 can slide without causing hindrance to elongation of the fixed shaft 8. Therefore the fixed shaft 8 is free from fear of deformation.

有していた。However, in the above configuration, the fixed shaft 3 generates thermal expansion due to heat conduction from the motor attached to the moving unit 4 and frictional heat of the sliding surface during continuous use. For this reason,
The fixed shaft 3 and the bracket 2I'i, which are fixed at both ends, are deformed, and the movement of the moving unit 4 is obstructed, so that accurate positioning cannot be performed. Furthermore, the fixed shaft 3 and the bearings 6 of the moving unit 4 have the disadvantage that wear is accelerated and the life of the device is shortened.

。Structure of the Invention The present invention provides a moving unit that performs a positioning operation, a fixed shaft that guides and slides the moving unit, a placket that fixes one end of the fixed shaft, and a placket that has a bearing that supports the free end of the fixed shaft. The expansion and contraction of the fixed shaft due to thermal expansion is counteracted by supporting the free end of the fixed shaft with one end fixed by a bearing, eliminating deformation of the identification shaft and reducing wear of the fixed bolt and the bearings of the moving unit. This has a unique effect in that the life of the device can be maintained for a long time without being accelerated.
