Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a ski fixing device used for fixing a ski to a work table or the like and a ski fixing device using the same.

(Prior Art) Generally, when wax is applied to a skiing surface of a ski, the ski is fixed to a workbench such that the skiing surface is directed vertically upward. The ski and the worktable are fixed with a fixture. One of the fixtures is a vise. When fixing the ski and the work table with a vice, a pair of vise is arranged at a distance from each other and fixed to the work table. A ski is arranged between the movable vice and the fixed pawl, and the distance between the movable vice and the fixed pawl is adjusted.
The skis are fixed by the movable pawl abutting one edge of the ski and the fixed pawl abutting one edge of the ski and the fixed pawl abutting the other edge of the ski, and the ski is fixed. The running surface of the plate is held vertically upward.

However, when the distance between the movable vice and the fixed pawl of the vise is adjusted to a value smaller than a predetermined value, one edge of the ski comes in contact with the movable pawl and the other edge of the ski contacts the fixed pawl. By being in contact with the ski, a force in the width direction acts on the ski, so that the ski is elastically deformed in an arc shape along the width direction, and the skiing surface of the ski is deformed into a curved surface. . As a result, at the time of finishing the wax film after the wax application, the edge of the scraper for scraping off the convex portion of the wax film does not evenly contact the wax film on the sliding surface, and the wax film on the sliding surface has a uniform thickness. I cannot finish it. When fixing a ski having a small thickness or a ski having a trapezoidal cross section to a vise, the contact area between one edge of the ski and the movable pawl and the other edge of the ski are fixed. Because the contact area with the nail becomes smaller,
It is difficult to hold the ski with a movable claw and a fixed claw without elastically deforming the ski in an arc along the width direction.

In order to hold the ski without elastically deforming it in an arc along the width direction, a suction-type fixing device has been proposed. The suction-type fixing device includes a fixing member attached to a worktable and a suction plate having a bottom attached to the fixing member and made of a dish-shaped elastic body. When using the suction-type fixing device, the pair of suction-type fixing devices are arranged at an interval from each other, and the fixing member is attached to the workbench such that the suction plate faces vertically upward. The ski is then placed above the suction disc such that its upper surface faces the suction disc. The ski is pressed against the suction disc and the upper surface of the ski contacts the edge of the suction disc. By further pressing the ski against the suction board, the suction board is sucked onto the upper surface of the ski, and the ski is fixed to the worktable with a suction-type fixture.

(Problems to be solved by the invention) However, when a large external force acts on the ski due to a work such as a wax application operation, the ski is an elastic body. It is difficult to hold the ski stably because it is moved in the direction of action and tilts with respect to the work table. Also, when the flaw formed on the upper surface of the ski faces the edge of the suction disc, the space formed between the upper face of the ski and the suction disc communicates with the outside via the flaw, The attraction force of the suction disc on the ski decreases with time, and the ski is released from the suction disc with a slight external force. as a result,
This leads to a decrease in work efficiency.

SUMMARY OF THE INVENTION An object of the present invention is to provide a ski fixing device capable of stably holding a ski without elastically deforming the ski in an arc shape along a width direction thereof and without changing a posture of the ski by an external force. It is an object of the present invention to provide a ski fixing device capable of preventing a decrease in work efficiency by using the same.

(Means for Solving the Problems) The ski fixing device of the present invention has an internal housing space opened on the upper surface and a seat member provided with a flow path communicating the internal housing space with the outside. A pedestal attached to a pedestal such as a pedestal, and one end is inserted into the flow path of the seat member,
A tubular shaft member attached to the seat member and extending coaxially with the opening in the internal housing space, a bottom portion is attached to the other end of the shaft member, and an outer edge portion is formed from the opening of the internal housing space of the seat member. A suction member protruding to the outside and made of a dish-shaped elastic material, wherein a hole communicating with an opening at the other end of the shaft member is provided at a bottom portion of the suction member; The seat member is inclined with respect to an axis, or the seat member is rotatable about an axis orthogonal to the axis of the opening.

It is preferable that the pedestal has a clamp member detachably attached to the pedestal, and the clamp member and the seat member are fixed.

In the seat member, an opening at one end is an outlet of the flow path,
A cylindrical portion having an opening at the other end serving as an inlet of the flow path, and a flange provided at the other end of the cylindrical portion so as to be rotatable around an axis of the cylindrical portion, and the internal accommodation space being provided. And the butting surface of the flange is the upper surface, and the shaft member is preferably attached to the tubular portion.

A screw is formed on the outer peripheral surface of the shaft member, a female screw is formed on the inner peripheral surface of the cylindrical portion, and the external screw of the shaft member and the female screw of the cylindrical portion are screwed. Is preferred.

A ski fixing device according to the present invention includes a plurality of ski fixing devices according to claim 1, a pipe connecting the flow paths of the ski fixing devices to each other, and a suction port fixed to each ski via the pipe. A suction device, such as a vacuum pump, that is connected to the flow path of the tool and suctions gas.

 Preferably said tube comprises a flexible tube.

(Operation) When wax is applied to the ski surface of the ski, the ski fixing device of the present invention is used.

When using the ski fixing device of the present invention, the pedestal is attached to the pedestal. Next, the upper surface of the ski opposing the sliding surface is pressed against the suction member. Since the outer edge of the attraction member projects outside from the opening of the seat member, the upper surface of the ski is abutted against the outer edge of the attraction member, so the attraction member is covered with the ski,
A closed space is formed between the attraction member and the ski so as to be shielded from the outside.

Further, when pressing the ski against the suction member,
Since the suction member is made of a dish-shaped elastic material, the outer edge of the suction member is bent toward the upper surface of the seat member. Therefore, the suction member is sandwiched between the ski and the seat member. Be included.

Further, the outer edge of the attraction member is substantially uniformly compressed between the seat member and the ski, so that the outer edge of the attraction member and the upper surface of the ski are securely brought into close contact with each other. As a result, the closed space formed by the suction member and the ski is reliably shut off from the outside, and the air in the closed space is sucked to the outside through the hole of the suction member and the flow path, thereby making the ski Is firmly adsorbed to the adsorbing member.

When an external force, such as a wax application operation, acts on the ski that is being sucked by the attraction member, the outer edge of the attraction member is sandwiched between the ski and the seat member, and the bottom of the attraction member is By being fixed to the shaft member, the attraction member is less likely to be relatively moved with respect to the seat member by an external force transmitted thereto from the ski, so that the attitude of the ski is less likely to be changed by the external force. Further, since the attraction force of the attraction member does not act in the width direction of the ski, the ski is not elastically deformed in an arc shape in the width direction.

The upper surface of the seat member is inclined with respect to the axis of the opening, or the seat member is rotatable around an axis orthogonal to the axis of the opening, so that the inclination direction of the upper surface of the seat member is The inclination direction of the upper surface of the ski can be matched.

Since the pedestal has the clamp member, the work of detaching from the pedestal becomes easy.

By rotating the flange of the seat member around the axis of the tubular portion, the inclination direction of the abutting surface of the flange can be changed relative to the base, so that the seat member can be moved to the base. The inclination direction of the abutting surface of the flange can be made to coincide with the optimum direction according to the mounting position and the like.

When the male screw of the shaft member and the female screw of the tubular portion are screwed together, the shaft member is released by releasing the screwing of the male screw of the shaft member and the female screw of the tubular portion. Since the suction member is detached from the cylindrical portion, the suction member fixed to the shaft member can be removed from the seat member, and the replacement of the suction member can be easily performed.

The ski fixing device of the present invention includes the ski fixing device, whereby the ski is firmly adsorbed to the suction member of the ski fixing device, and the ski fixing device is applied by an external force acting on the ski. Since the attraction member is not relatively moved with respect to the seat member, the ski can be stably fixed to the base, and a decrease in work efficiency performed on the ski can be prevented.

Since the tube is made of a flexible tube, the distance between the ski fixing devices adjacent to each other is not limited, so that the ski fixing device can be freely arranged.
