DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-cylindrical ceramic material which has been polished into a cylindrical shape with a polishing jig before firing, and more particularly to a high-frequency heating device incorporated in a mounting table motor. .

[0002]

2. Description of the Related Art Conventionally, in this processing method, as shown in FIG. 6, after adjusting the raw material, the raw material is formed into a non-cylindrical shaft, and after firing, dimensions are determined in six polishing steps. The molded product was finished to a finished product through three of six steps for polishing the corners of the non-cylindrical shaft.

[0003]

However, the conventional processing method has a problem in that the non-cylindrical shaft is soft before firing and cracks or the like occur when the shaft is polished. Therefore, the non-cylindrical shaft was polished after firing. Moreover, since the ceramic shaft after firing is hard, it takes three steps to grind the corner of the non-cylindrical shaft, it takes time, and there is a problem that expensive artificial diamond must be used to grind. I was

[0004]

According to the present invention, in order to solve the above-mentioned problems, as shown in FIG. 5, the non-cylindrical ceramic shaft immediately after molding is soft, so that the angle of the non-cylindrical shaft is set immediately after molding. The polishing is made possible by using air so that no load is applied for the polishing. According to the above invention, the polishing step after firing is reduced by three steps, so that the time and the capital investment can be reduced.

[0006] A polishing jig having a non-cylindrical shaft and a polishing surface on the inside, and a transfer unit for transferring the rotating body and the shaft are provided. This is a cylindrical material processing device that enables mass production by being provided.

[0007] A heating chamber for storing and heating a heated object, a heating object mounting table provided in the heating chamber for mounting and rotating the heated object, and a weight sensor element for measuring the weight of the heated object. A transmission shaft and a mounting table motor for rotating the heated object mounting table with the shaft, the polishing jig itself configured with an abrasive on the polishing surface is moved back and forth, and has a non-cylindrical shape before firing. A high-frequency heating apparatus having a configuration in which a surface of a ceramic shaft is polished into a cylindrical shape, fired, and the shaft is further polished so as to have a predetermined size, which is incorporated in the mounting table motor. .

An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are sectional views of a main part of a cylindrical material processing apparatus according to a first embodiment of the present invention. FIG. 3 is an external view of the cylindrical material processing apparatus. FIG. 4 is an external view of the high-frequency heating device. FIG. 5 shows a processing step using a cylindrical material processing apparatus.

FIG. 5 shows a molded article which has been formed after adjusting the raw materials, has a non-cylindrical shaft, and then grinds the corner of the non-cylindrical shaft with a cylindrical material processing apparatus. Therefore, as shown in FIG. 1, the polishing jig 7 is formed in a semicircular shape so that the shaft 4 can be mounted thereon, and an abrasive 8 for polishing the shaft 4 is mounted between the polishing jig 7 and the shaft 4. ing. Polishing jig 7
A hole for sucking / discharging the air 10 is provided in the semicircular bottom surface. Axis 4 with air 10 from this hole
By moving the polishing jig 7 in the longitudinal direction while sucking the
The configuration is such that the corners of the shaft 4 can be polished by the friction between the material and the abrasive material 8. At this time, the ceramic powder generated at the time of polishing is also sucked by the suction force of the air 10 at the same time. Also, as shown in FIG. 2, the discharged air 10 pushes up the shaft 4 and brings the shaft 4 into contact with the rotating body 11 mounted above the polishing jig 7 so that a new processing surface appears, and The unprocessed surface is polished. FIG. 3 shows a transport unit 9 for transporting the shaft 4 for mass production of the shaft 4, and a wall for fixing the shaft 4 because the polishing jig 7 moves in the longitudinal direction. I have.

FIG. 4 shows a state in which the object 2 is placed on a heating table 3 provided in a heating chamber 1 in which the object 2 is housed and heated.

[0011]

As described above, the present invention has the following advantageous effects.

(1) By suctioning with air, the polishing effect of the non-cylindrical shaft is improved, and it is possible to sharpen quickly and at the same time to suck in powder generated during polishing. Further, by moving in the longitudinal direction, the corner of the non-cylindrical shaft can be rounded.

(2) The discharge by air and the rotation by the rotating body does not apply a load to the soft non-cylindrical ceramic shaft, and a stable quality can be obtained without generating defects such as cracks.

(3) By configuring the transfer unit when polishing a non-cylindrical shaft, mass production with stable quality is possible without contact between non-cylindrical shafts.

(4) By polishing the non-cylindrical shaft before firing, three polishing steps after firing can be reduced. Further, since the processing time can be reduced and the capital investment can be reduced, the total processing cost can be reduced, and finally, the product cost can be reduced.
