DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a height adjusting device for adjusting the height of various devices.

[0002]

2. Description of the Related Art In a cable manufacturing process and the like, a traveling cable is passed through a visual inspection device to inspect the peripheral surface of the cable for defects. At the time of this visual inspection, it is necessary to adjust the height of the visual inspection device according to the outer diameter of each cable to be inspected. FIG. 4 shows a main part of a conventional height adjusting device. In the drawing, reference numeral 1 denotes an appearance inspection device. A cable 3 is coaxially passed through the circular through hole 2 of the visual inspection device 1, and when the cable 3 runs, the presence or absence of a defect on the peripheral surface is detected by a plurality of sensor units 4.

The conventional height adjusting device includes a mounting plate 5 on which the appearance inspection device 1 is mounted, and a fixing plate 6 which is arranged below the mounting plate 5 so as to be opposed to the mounting plate 5. The center of the mounting plate 5 supports the head 8 of the height adjustment bolt 7 in a state where the head 8 is rotatably inserted at a fixed position, and the screw portion of the height adjustment bolt 7 extends downward to fix the fixing plate. 6, and is screwed into a screw hole 9a of a column 9 which fixedly supports the fixing plate 6. Guide tubes 10 are fixed to both sides of the fixed plate 6 so as to penetrate along the vertical direction, and anti-rotation rods 11 protruding from the lower surface of the mounting plate 5 are inserted into these guide tubes 10.

When the head 8 of the height adjusting bolt 7 is turned with a wrench (not shown) in the height adjusting device having the above-described configuration, the height adjusting bolt 7 enters or projects into the screw hole 9 a of the support 9. The mounting plate 5 moves up and down accordingly. Accordingly, the height of the visual inspection device 1 is adjusted accordingly.

[0005]

However, in the above-described conventional height adjusting device, the weight of the visual inspection device 1 is reduced by the mounting plate 5.
, The bolt is directly applied to the height adjusting bolt 7, so that a very large force is required when the head 8 is turned with a wrench, and there is a disadvantage that a great burden is imposed on the operator. In addition, there is some play between the head 8 of the height adjustment bolt 7 and the mounting plate 5 because the head 8 needs to be turned, so that the mounting plate 5 It may move up and down non-parallel. Therefore, in this case, the rotation preventing rod 11 is
Since it moves up and down while being strongly pressed against the inner surface, there is a drawback that a larger force is required when turning the head 8. The present invention has been made in order to solve such a point, and an object of the present invention is to provide a device height adjusting device that can adjust the device height with a small force.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a device height adjusting device 2 according to the present invention.
FIG. In FIG. 1, reference numeral 21 denotes an apparatus main body, and an elevating table 22 is attached to the apparatus main body 21 so as to be able to move up and down. That is, a guide groove 21A is provided on the rear side of the apparatus main body 21 along the up-down direction.
A is slidably engaged. Therefore, the elevating platform 22 rises or descends along the guide groove 21A via the rear projection 22A.

An inclined surface 22B is formed at the lower end of the elevating table 22, and a guide rail 23 is attached to the inclined surface 22B. A slide member 24 having a substantially U-shaped cross section is slidably engaged with the guide rail 23. The slide member 24 is fixed to the upper surface of the moving body 25, and the lower end of the moving body 25 has a guide groove 2 on the upper surface of a support plate 26 which is disposed horizontally.
6a. Therefore, the weight of the visual inspection device 1 mounted on the mounting plate 27 on the lift 22 is added to the support plate 26 via the lift 22, the slide member 24, and the moving body 25. The support plate 26 is arranged so that bolts 29, 29 penetrating through the base 28 are inserted and can be moved up and down, that is, only movement in the horizontal direction is restricted.
When the pressing screws 30, 30 penetrating the base 28 are tightened, the pressing screws 30 are lifted by the tips thereof, and the height position thereof is set while being pressed against the moving body 25. Thus, the support 26 supports the weight of the appearance inspection apparatus 1 and prevents the weight from being added to a feed screw rod 31 described later.

A feed screw rod 31 is screwed into the lower part of the moving body 25 in a state of penetrating therethrough. The feed screw rod 31 is arranged in a horizontal direction, and one end is rotatably supported by a bearing portion 32 attached to a lower portion of an outer wall of the apparatus main body 21. The other end of the feed screw rod 31 penetrates the other outer wall of the apparatus main body 21, is rotatably supported by a bearing 33, and has a handle 34 attached thereto. Handle 3
4 is provided with a grip 34a.

Next, the operation of the height adjusting device 20 according to the present invention will be described. The cable 3 is passed through the circular through hole 2 of the visual inspection device 1, and a defect on the peripheral surface of the cable 3 is detected by the plurality of sensor units 4 during traveling. When the handle 34 is turned by holding the grip 34a of the handle 34 by hand,
Since the feed screw rod 31 rotates, the moving body 25 screwed to the feed screw rod 31 moves in the horizontal direction.

When the moving body 25 moves, the slide member 24 also moves with it, so that the elevator 22 moves up or down. In this case, the weight of the appearance inspection device 1 is
, The handle 34 can be rotated with a small force. Also, by setting the screw pitch of the feed screw rod 31 small, the height position can be finely adjusted. Further, since there is no play between the slide member 24 and the guide rail 23 and between the movable body 25 and the feed screw rod 31, the lift 22 can be always raised and lowered smoothly.

FIG. 2 is a partial sectional view showing a modification of the height adjusting device shown in FIG. In this modification, a lifting bolt 36 is screwed into the base 28 from below. The lifting bolt 36 is integrally fixed with a washer 38 on the tip end side.
The washer 38 is locked to the lower surface of the support base 26 with the distal end portion 36a inserted into the concave portion on the lower surface of the support base 26. A lock nut 37 is screwed into the base side of the lifting bolt 36 via a washer 39, whereby the lifting bolt 36
Is fixed. Therefore, the support base 26 can be pressed against the lower surface of the moving body 25 via the washer 38 by screwing in the lifting bolt 36, and the horizontal movement of the support base 26 can be prevented. Therefore, it is not necessary to use both the bolt 29 and the pressing screw 30 as in the embodiment of FIG.

FIG. 3 is a front view showing another embodiment of the height adjusting device 20 according to the present invention. In this embodiment, the moving body 25 is not supported by the support plate 26 (see FIG. 1), but is directly supported by the feed screw rod 31. The other end of the feed screw rod 31 is prevented from rotating (reverse rotation) by pressing the tip of a reverse rotation preventing screw 35 provided on the bearing portion 33. In this embodiment, the reverse rotation preventing screw 35 is loosened and the handle 34 is turned to move the moving body 25 with the feed screw rod 31.
Is moved in the horizontal direction, whereby the slide member 24 is slid to move the lift 22 up or down. After the height adjustment is completed, the rotation preventing screw 35 is tightened to prevent the feed screw rod 31 from rotating.

In the embodiment shown in FIG. 3, the weight of the visual inspection device 1 is added to the feed screw rod 31, but the moving body 25 is moved in a horizontal direction perpendicular to the vertical direction where the weight is added. Can be rotated with a small force. Since the weight of the feed screw rod 31 directly adds to the weight of the device, it is preferable that the diameter is slightly increased to maintain rigidity. In the above-described two embodiments, the height adjusting device 20 according to the present invention is used for adjusting the height of the visual inspection device 1, but can be used for other devices that require height adjustment.
