[Prior art]

 FIG. 6 is a front view of a conventional foot type cylinder 80.

As shown in FIG. 6, a foot-type cylinder 80 includes a cylinder body 82 and mounting brackets 83a and 83b. The cylinder body 82 includes a cylinder tube, a cover, a piston (not shown), a piston rod 81, and the like. The mounting brackets 83a and 83b are fixed to the cylinder body 82 by four bolts 84a to 84d. Instead of the bolts 84a to 84d, a tie rod and a nut penetrating the cylinder body 82 may be used. The mounting brackets 83a and 83b are fixed to the gantry 84 by four bolts 85a to 85d.

A male screw 81E is provided at the tip of the piston rod 81, and is screwed into a female screw 86I provided on the work 86. Although not shown, a lock nut is usually attached to the male screw 81E.

In order for the work 86 to move smoothly, it is necessary that the axis of the piston rod 81 and the axis of the female screw 86I of the work 86 match in height and parallelism. Conventionally, when the shaft center of the piston rod 81 is lower than the shaft center of the female screw 86I, shims 87a to 87d are inserted between the mounting brackets 83a and 83b and the base 84 so that the foot type cylinder 80 Is adjusted from the gantry 84. Thus, the piston rod 81 and the female screw 86I are aligned.

[0006] The work of centering by inserting the shims 87a to 87d is performed, for example, as follows. That is, a number of shims of the same or different thicknesses are prepared in large numbers, and a shim that is considered to be appropriate among the shims is loosened by loosening the bolts 85a to 85d, and the bolts 85a to 85b of the mounting brackets 83a and 83b are removed. After inserting at the position of 85d, the bolts 85a to 85d are tightened again. By moving the piston rod 81 in the axial direction and seeing whether or not the work 86 moves smoothly, it is determined whether or not the axis of the piston rod 81 and the axis of the female screw 86I exactly match at each position. Check if. If they do not match exactly, loosen some or all of the bolts 85a-85d, replace them with another shim, and repeat the same operation.

[0007]

[Problems to be solved by the invention]

 Thus, in the work of centering by inserting the shim, it is necessary to select a shim having an appropriate thickness, which is troublesome. If there is no shim with the optimum thickness, accurate alignment cannot be performed.

The present invention has been made in view of the above-mentioned problem, and provides an adjusting device for adjusting the height of a cylinder, which can accurately adjust the height of the cylinder by a simple operation. The purpose is to do.
