Description

[Detailed Description of the Invention] (A) Field of Industrial Application The present invention relates to a workpiece holder for stabilizing a workpiece without a clamping mechanism in an ultra-high pressure water processing device.

(B) Conventional technology Ultra-high-pressure water processing equipment that sprays ultra-high-pressure water to perform processes such as peeling and polishing materials has many advantages, such as generating less dust and noise and vibration. Because of this, it has recently been used in many ways.

However, if the workpiece is simply placed on a flat support jig, the workpiece will move due to the pressure of ultra-high pressure water. Therefore, conventionally, the workpiece was held down with a clamp. However, when the material is held down with a clamp, the part held down by the clamp is hidden and cannot be processed at once, and there is also the disadvantage that the part held down is damaged.

Therefore, it is conceivable to form a concave groove in the workpiece receiving jig according to the shape of the workpiece, and to insert and hold the workpiece into the concave groove. However, even with this receiving jig, when ultra-high pressure water is applied, the direction of the water escaping is opposite to the ultra-high pressure water jetting, so if the work is a light work, the work may fluctuate, resulting in unevenness. Processing becomes impossible.

(C) Problems to be Solved by the Present Invention Therefore, in the present invention, a concave groove is formed in the workpiece receiving jig according to the shape of the workpiece, and a notch for water escape is formed on the convex edge forming the periphery of the concave groove. , furthermore, the bottom of the concave groove,
In other words, by providing a through hole or a conduit groove on the bottom of the main body, the workpiece is held down and the water is directed horizontally or in the same direction (downward) as the ultra-high pressure water jet.
This is intended to prevent the occurrence of flapping by allowing the air to escape.

(D) Means for Solving the Problem In order to solve the above-mentioned problems, the present invention aims to solve the above-mentioned problems by using a workpiece receiving jig 1 having a groove 2 formed therein according to the shape of the workpiece in ultra-high pressure water processing equipment. 2, a water escape groove 3 is provided laterally to the outside by cutting out the convex edge 4, and a through hole 6 is provided inside the convex edge 4, with the convex edge portion having an open groove shape and penetrating through the bottom part 5 of the main body. It is an object of the present invention to provide a workpiece receiving jig characterized by the following features.

(E) Example Figure 1 shows the first example in the scope of the utility model registration claim.
It is a perspective view of a 1st Example corresponding to a claim.

A groove 2 corresponding to the shape of the workpiece is formed on the upper surface of the workpiece receiving jig 1. If there is a large gap between the side surface of the workpiece and the side surface of the groove 2, the workpiece will fluctuate, so the groove 2 should be made so that the side surface of the workpiece contacts the side surface of the groove 2 to the extent that handling is not inconvenient. It is formed to match the dimensions of the workpiece.

A water escape groove 3 extending laterally outward from the groove 2 is provided by cutting out a convex edge 4 forming the periphery of the main body of the workpiece receiving jig 1. The water escape grooves 3 are cut out in four places in the center of the front edge, rear edge, left edge, and right edge of the convex edge 4 of the workpiece receiving jig 1, up to the bottom surface 5 of the groove 2. It is provided.

This allows the water on the top surface of the workpiece to escape no matter which direction the water flows in, front, back, left, or right. Further, since the workpiece is thick, water will fall into the water escape groove 3 and will not accumulate on the upper surface of the workpiece. It is desirable for the width of the water escape groove 3 to be wide enough to allow a finger to be inserted when taking out a workpiece.

A through hole 6 is provided inside the convex edge 4 in the shape of an open groove in which the convex edge portion is cut out in a semicircular shape and passes through the bottom of the work body. The through holes 6 are provided at several locations on each edge with respective water escape grooves 3 in between.
Thereby, water that tends to collect around the four corners of the workpiece, which is difficult to flow into the water release groove 3, can be released.

FIG. 2 is a perspective view of the second embodiment.

In the second embodiment, in addition to the structure of the first embodiment, a water release groove 3 is provided on the bottom surface 5 of the groove 2 of the workpiece receiving jig 1.
A water conduit groove 7 extending to the tip of the concave groove 2 is formed to be orthogonal to the center of the bottom surface 5 of the concave groove 2 .

FIG. 3 is a perspective view of the third embodiment. In the third embodiment, the groove bottom surface 5 in the second embodiment is
In place of the water conduit groove 7 cut out in the groove, a through hole 8 for water escape is bored through the bottom of the concave groove. In this embodiment, the through hole 8 is a line connecting the bottom surface 5 of the concave groove 2 with the water escape grooves 3 cut out at the front and rear edges, respectively, and the water escape grooves 3 cut out at the left edge and right edge, respectively.
A total of four holes are drilled, one on each side divided into four equal parts by the line connecting the two. This allows the water that has flowed to the bottom of the workpiece to escape wherever it goes.

It should be noted that other embodiments may be considered in which the water conduit groove 7 in the second embodiment and the through hole 8 in the third embodiment are formed at the same time.

(F) Effect The effects of the examples will be explained below.

By forming the concave groove 2 in the workpiece holding jig 1 according to the shape of the workpiece, the workpiece can be held down, so there is no need to spray ultra-high pressure water on the held part again, unlike when holding down with a clamp. No more scratches caused by the clamp foot.

In response to the injection of ultra-high pressure water, the used water can escape horizontally through the water escape groove 3 and in the same direction (downward) through the through hole 6, so that the water can escape in the opposite direction to the injection. Workpiece flapping can be prevented.

Regarding the workpiece receiving jig 1 in the present invention,
By inserting your finger into the cutout water escape groove 3,
Workpieces can be easily taken out after processing.

In the second and third embodiments, when ultra-high-pressure water is injected onto a frame-shaped workpiece, even if used water flows to the bottom of the workpiece, it will not flow through the water conduit 7 or the through hole 8. It is something you can escape through.
