Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for attaching a steel pole to a predetermined location such as a bearing.

Conventionally, this type of steel pole was installed by applying high viscosity oil such as grease to the brush, attaching the steel poles to the tip of the brush one by one, and placing them in a designated location such as a bearing. etc. can easily get dirty by adhering to other things,
It is necessary to constantly check whether the required number of steel poles have been correctly attached to the predetermined locations, and the work is complicated and time-consuming.

In view of the above-mentioned circumstances, the present invention provides a device for accurately attaching a required number of steel poles at a time to predetermined locations coated with grease, using air suction instead of manual work such as the tip of a brush. The inner cylinder, which has an opening for connecting the near compressor and an opening for ventilation formed in the surrounding wall, has an inner cylinder that is closed at the upper end and has an opening formed on the surrounding wall, and is slidable in the vertical direction. At the same time, a steel pole suction attachment is removably attached to the lower end of the outer cylinder, and when connected to the air sprayer 2, the inner cylinder is slid vertically to open the opening of the outer cylinder. By aligning the opening with the near compressor connection opening or the ventilation opening, the steel pole can be attracted to or released from the steel pole attachment.

Hereinafter, the present invention will be explained based on illustrated embodiments.

The illustrated steel pole mounting device is constructed by fitting an inner cylinder 2 into an outer cylinder l so as to be slidable in the vertical direction, and a steel pole suction attachment 3 is detachably attached to the lower end of the outer cylinder 1. .

As shown in the second and third figures, the peripheral wall of the outer cylinder 1 is provided with a cylindrical opening isthmus 11 protruding from its approximately central height position, which is connected to a near compressor (not shown) via a connecting hose B. A screw hole 13 for screwing the retaining pin 12 above it
However, a small diameter ventilation opening 14 is formed below it. Further, a threaded portion 15 is formed at the lower end of the peripheral wall of the outer cylinder 1 to be screwed into the steel pole adsorption attachment 3.

The inner cylinder 2 has a small-diameter opening 22 and an axial slit 23 formed on its peripheral wall, which correspond to the cylindrical opening 11 and the engagement pin screw hole 13 of the outer cylinder 1, respectively, and closes the upper end side. The flat screw 21 has a flange-shaped head and is fitted into the outer cylinder l with an outer diameter approximately equal to the inner diameter of the outer cylinder l. The inner end of the integrated pin 12 screwed into the engagement pin screw hole 13 of the outer cylinder l protrudes and engages with the slit 23 of the inner cylinder 2, thereby limiting the relative sliding range of the inner cylinder 2 with respect to the outer cylinder l. When the engagement pin 12 contacts the lower end of the slit 23, that is, at the maximum upward sliding position of the inner cylinder 2, the opening 22 of the inner cylinder 2 is (see FIG. 2); conversely, when the retaining pin 12 contacts the upper end of the slit 23, that is, at the maximum downward sliding position of the inner cylinder 2, the opening 22 is used for ventilation of the outer cylinder 1. It is configured to coincide with the opening 14 (see FIG. 4). Further, a spring 4 is interposed between the top of the outer cylinder 1 and the flange-shaped head of the flat screw 21 of the inner cylinder 2.
The inner cylinder 2 is urged to its upward sliding position.

As shown in Figures 2 and 5, the steel pole suction attachment 3 has a spiral portion 15 of an outer cylinder l on the inner wall of its upper end opening.
A spiral portion 31 is formed to engage with the steel pole, and a predetermined number of steel pole suction holes 32 are provided at predetermined positions at the lower end. The shape of this attachment 3, especially the shape of the lower end, corresponds to the shape of the area around the steel pole mounting position of the bearing c@c', C", etc., and is configured so that they can be fitted together. (See Figure 4.6φ7).

When the steel pole mounting device configured in this way is positioned above the stocker A of the steel pole a and then operates the near compressor (not shown), the suction hole 32 of the attachment 3, the opening 22 of the inner cylinder 2, etc. , outer cylinder 1
Outside air is sucked in through the cylindrical opening acid part 11, and one steel pole a is sucked into each suction hole 32 of the attachment 3 by this suction force. After adsorbing the steel pole a, move the entire device to the vicinity of the installation position of the steel pole such as the bearing C, and with the attachment 3 aligned with the installation position of the bearing, tighten the flat screw 21 against the biasing force of the spring 5. When pressed, the inner cylinder 2 relatively slides vertically within the outer cylinder 1 so that the opening 22 of the inner cylinder 2 coincides with the ventilation opening 14 of the outer cylinder l, and the peripheral wall of the inner cylinder 2 causes the outer cylinder l to
The cylindrical opening isthmus 11 is closed, the suction of the steel pole is released, and the steel pole a is placed in a predetermined position such as a bearing. In addition, steel pole adsorption attachments 3 and 3' are available depending on the shape of the bearing etc. on which the steel pole is attached.
・By replacing 3'', various bearings C, C'',
It can be used for C11 etc.

As described above, according to the steel pole attaching device according to the present invention, a required number of steel poles can be attached to a predetermined location such as a bearing at once and accurately.
