Description

DETAILED DESCRIPTION OF THE INVENTION "Object of Invention" (Field of Industrial Application) The present invention relates to a polishing apparatus for a sample for emission spectroscopic analysis, fluorescent X-ray analysis or other instrumental analysis.

(Prior art) Polishing of a sample for instrumental analysis is generally carried out by holding a sample to be polished on a magnet with a frame and holding it in hand and pressing it against a belt sander rotating at high speed. It is common to polish.

That is, FIGS. 6 to 7 show a typical polishing jig, FIG. 6 is a side view thereof, and FIG. 7 is a bottom view thereof. Has a projection 2a formed therein. The projection 2a serves to lock and fix the sample 3 to the sample 3 when polishing the sample 3 while adhering it to the bottom surface of the magnet 2 and to prevent the sample 3 from coming off. . Polishing is performed by pressing the surface of the sample 3 described above against the belt sander surface that rotates at a high speed.

(Problems to be solved by the invention) In the conventional polishing method as described above, in order to hold the magnet with a frame in a free state and press it against the belt sander,
The pressing force applied to each part of the framed magnet (that is, the sample) is manually adjusted, and considerable skill is required to form a desired smooth surface for analysis, and individual differences are likely to occur. Further, since the whole magnet must be grasped and pressed by the fingertip, it is difficult to hold, and when continuously polishing the sample, the arm and the finger become painful and considerably fatigued. In addition, there were many problems that the sample peeled off from the magnet during polishing and jumped out depending on the force applied. The present invention has been devised in view of the above circumstances, and an object thereof is to provide a safe polishing apparatus that is relatively inexpensive and has no individual difference in the polishing surface of the sample. is there.

[Construction of the device] (Means for solving the problem) A shaft barrel of a machine frame is rotatably and movably attached to a rotating and moving shaft provided along the width direction of a belt sander, and polishing is performed on the machine frame. A sample attaching / detaching portion is formed so that one end side of a magnet for attaching / detaching a sample to be attached is pivotally attached, and the sample attaching / detaching portion presses the other end side of the magnet via a spring. A polishing apparatus for a sample for instrumental analysis, characterized by being provided with.

(Operation) A machine shaft having a sample attaching / detaching part and a polishing surface pressure adjusting mechanism and a rotating / moving shaft for the machine frame are attached to a guide shaft provided along the width direction of the belt sander, and one end of a magnet is attached to the machine frame. Since the side is pivotally attached, one end side of the magnet pivotally attached to the machine frame can be used as a reference to press the sander belt for polishing. That is, one end side of the magnet pivotally attached at the time of polishing is standardized (positioned) and pressed by the pressing force at the other end side, so that stable uniform polishing with suppressed individual difference can be performed.

In order to set the sample to be polished on the machine frame, the magnetic force by the magnet used can be easily attached and detached by turning the magnet on and off as in the strong switching method. By using an adjusting screw that presses the end portion via a spring, a uniform polished surface with no difference between the respective positions on the sample surface can be obtained, and the shock during polishing is softened. Further, the adjusting screw acts as a positioning stopper so that the lower surface of the magnet does not completely lower to the belt sander surface.

In addition, since the shaft cylinder of the machine frame is rotatably and movably attached to the rotation and movement shaft and pivotally attached, the polishing state and the retracted state are appropriately formed to rotate the machine frame to both the mounting and demounting of the sample and the polishing position. In addition, it is possible to prevent the polishing from being always performed only at a specific position in the belt sander width direction, and to avoid uniform abrasion of the polishing belt surface. As described above, it is equipped with the attachment / detachment mechanism and the mechanism for adjusting the position, angle, and pressing force of the polishing surface, and also has the rotation and movement mechanism of the polishing machine for uniformly and freely using the entire area of the belt sander. There is no individual difference in the polished surface, and the service life is extended in terms of equipment.

(Embodiment) Explaining an embodiment of the present invention as described above, the present invention has a sample attaching / detaching portion for the belt sander as described above, and a polishing surface of the sample attached to the sample attaching / detaching portion. The polishing machine is provided with an adjusting means for the.

Regarding the sample attaching / detaching part, in order to set the sample to be polished, the magnetic force is used also in the present invention,
Moreover, the strong magnet can be easily attached and detached by switching on and off. In addition, an adjustment screw that uses a spring is used between the polishing machine and the sample (including magnet) to obtain a uniform pressure contact polishing state with virtually no difference between each position on the sample surface and the impact during polishing. Try to relax.

By using a position adjusting screw separately between the polishing machine and the magnet, the sample polishing surface for the belt sander can be appropriately selected and set even when the sample thickness changes significantly.

Also, from the viewpoint of protection of the polishing belt surface, the contact between the polishing surface and the belt sander should be slightly different from the sample surface so that the edge of the polishing surface of the sample does not damage the polishing belt. It is necessary to set the magnet so that it is separated from the belt, and it is preferable that the position of the support screw of the magnet is slightly shifted to the entrance side.

Referring to the drawings, a concrete device according to the present invention will be described.
