っている。Conventionally, devices with various structures have been developed as devices for automatically polishing the surface of articles.
Barrel polishing devices disclosed in Japanese Patent No. 9156 and Japanese Patent No. 45-34360 are known. This polishing device has a plurality of cylinder supports supported on the outer periphery of a rotary drum parallel to the rotation axis of the rotary drum, and each of these cylinder supports has a plurality of cylinder supports symmetrically with respect to the axis of the cylinder support. Attach hollow cylindrical or prismatic cylinders, store an abrasive material and an object to be polished in each cylinder, and connect the rotary drum to a motor using a wet or dry polishing method, and fix each cylinder holder. The structure is such that the plurality of cylinders attached to each cylinder holder rotate as a unit as the rotary drum revolves, and the central axis of each cylinder is connected to each cylinder holder. The connection between the rotary drum and the fixed part is achieved by meshing gears, and the rotation of the rotary drum is operated continuously.

適用できない。By the way, the above-mentioned conventional polishing device is very useful for simply removing deburrs and polishing the surface of articles, but for example, it can be used for polishing oscillating crystals in the shape of flat rods, strips, or spindle disks. It cannot be applied to cases where the object to be polished must be polished into a predetermined shape (a shape with a symmetrically processed curved surface), such as in the following.
その理由を上記発振用水晶を例にとって説明する。The reason for this will be explained by taking the above-mentioned oscillation crystal as an example.
まず、発振用水晶は第1図(1)(2)(3)の(a)
に示すように薄肉平棒状、短冊状、円盤状に切り出され

ンズ状にliを11aと11bを研磨する。First, the oscillation crystal is shown in (a) of Figure 1 (1) (2) (3).
As shown in the figure, a quartz single crystal piece i cut out in the shape of a thin flat bar, strip, or disk is polished, and its top and bottom surfaces ia, i are polished.
Leaving the center parts A and B of b, the outer periphery is shaved off with a constant curvature, and as shown in (b) of (1), (2), and (3), 11a and 11b of li are polished into a double-sided convex lens shape.
この様に一定の曲率で上下底面ia1山を図A、3面の
一部を残して研磨するためには、その−定の曲率を持つ
研磨面に、上記水晶単結晶lの上下底面ia、 ibを
同じ時間均等に摩擦させる様にしなければならない。In this way, in order to polish the top and bottom surfaces ia1 with a constant curvature while leaving a part of the three surfaces in Figure A, the top and bottom surfaces ia of the quartz single crystal l, The ib must be rubbed evenly for the same amount of time.

研磨体が激しく擾乱されることになる。However, in the above-mentioned polishing device, the abrasive material and the object to be polished in each cylinder are subjected to a force directed outward in the radial direction of the rotary drum due to the centrifugal force caused by the rotation of the rotary drum, and the material and object to be polished are pushed against the inner wall of each cylinder located outside the rotary drum. It's always being pushed. For this reason, the object to be polished and the polishing material are pressed against each other by a large centrifugal force, but at the same time, the cylinder rotates in the opposite direction to the rotation of the drum, so it flows against the inner wall of the cylinder.
Moreover, since the inner wall of the cylinder is provided with a rubber or synthetic resin layer having ridges, the abrasive material and the object to be polished are violently disturbed by this flow.
この様にして大きな圧力で互いに圧接している研磨材と
被研磨体とが互いに摺動して研磨が行われることになる

強く行われる部分はシリンダー内壁に直接接する研磨材
とその上にある被研磨体との間であり、この時の偏平形
状の被研磨体が反転する確率も大変少ない。In this way, the abrasive material and the object to be polished, which are in contact with each other under great pressure, slide against each other and polishing is performed. The surface will be polished almost evenly. In addition, when the object to be polished is a flat-shaped object, the part where strong sliding with the abrasive material occurs is between the abrasive material that is in direct contact with the inner wall of the cylinder and the object to be polished above it, and the flat shape at this time The probability that the object to be polished will turn over is also very low.
そのため偏平形状の被研磨体は、その上下各底面の一方
が特に余計に研磨される事になるし、またその研磨も所
定の曲率を持って行い得ない。Therefore, in the case of a flat object to be polished, one of its upper and lower bottom surfaces must be polished excessively, and the polishing cannot be performed with a predetermined curvature.

レンズ状に研磨成形することができない訳である。Therefore, with this polishing apparatus, it is not possible to polish and shape the quartz single crystal piece l into the shape of a double-sided convex lens.

明した。The present inventor has conducted extensive experiments in order to develop a barrel polishing device that can easily form products with flat and symmetrically processed curved surfaces, such as oscillating crystals in the shape of flat rods, strips, or spindle discs, by polishing. As a result of repeated consideration, the following points were found.

される。(b) No rubber or synthetic resin layer is provided on the inner surface of the cylinder, the inner surface is kept in a relatively smooth condition, and the entire inner surface of this cylinder has a curvature that is approximately the same as the processed curved surface of the product to be molded. The specified amount (0025% of the internal volume of the cylinder) is
When the rotary drum is rotated with an abrasive material of about 100 to 100 mm in diameter, the abrasive material in the cylinder is pressed against the inner wall of the cylinder by centrifugal force, forming an abrasive layer with a uniform thickness. As a result, a polishing layer is formed on the inner wall of the cylinder whose curvature is the same as that of the inner wall of the cylinder, that is, the same as the curvature of the curved surface of the processed product.
3) By sliding a spindle disk shape, a regular square disk, or a rectangular square disk shape, a curved surface with a desired curvature is formed on one bottom surface of the object to be polished.

り一層高まり均一円形に所要曲率の曲面が形成される。When the cylinder is rotated at a predetermined angle (7° to 15°) with respect to the rotation axis of the rotary drum, the abrasive material in the cylinder and the object to be polished slide, and one end of the cylinder and the other end of the cylinder are rotated. Since the polishing fluid flows continuously in a figure-eight pattern along the inner peripheral surface of the cylinder, the polishing efficiency is further increased and a uniform circular curved surface with the required curvature is formed.

リンダーに被研磨体を投入を研磨した場合、被研磨体は
長方円筒状シリンダーの長手方向、横軸方向のみで研磨
され縦軸方向には研磨されない事が判明した。However, it is impossible to polish the flat bar-shaped oscillating crystal piece shown in FIG. 1 (1). This is because when the object to be polished is put into the rectangular cylindrical cylinder shown in Figure 2 ■■, the object to be polished is polished only in the longitudinal direction and horizontal axis direction of the rectangular cylindrical cylinder, and not in the vertical axis direction. It turned out that it was not polished.
従って上記被研磨体を研磨する場合は第2図■■の球形
研磨シリンダーを使用する事で被研磨体(平棒状)を所
要の曲率の曲面にほぼ研磨することができる。Therefore, when polishing the object to be polished, by using the spherical polishing cylinder shown in FIG.

の曲面にほぼ研磨形成する事ができる。The object to be polished and 3 to 8 g of the abrasive material layer are placed in a spherical polishing cylinder, a plurality of spherical polishing cylinders are set in the polishing cylinder case, and the polishing is performed after being fixed to the polishing cylinder holder with a jig and a presser cover. The object to be polished is pressed and slid against the inner wall of the spherical polishing cylinder, and can be polished into a curved surface with a predetermined curvature in any direction.

る。(b) Development of a new polishing device In recent years, the high-tech industry has entered an era of lightness, thinness, and shortness, and the vibrator industry is also under pressure to increase production of small, flat rod-shaped vibrators.

形成される。A fully spherical continuous polishing cylinder (hereinafter abbreviated as spherical continuous polishing cylinder) is one in which two spherical poles are cut and successively joined into multiple pieces to form an integrated cylinder with lids on both ends. (See Figure 3 (2)) The spherical continuous polishing cylinder is made of a material such as metal, ceramic, or synthetic resin, and the inner surface is kept smooth.
The entire inner surface of this cylinder is molded to have the same curved surface curvature as the processed curved surface of the product to be molded, a predetermined amount (1 g to 5 g per ball) of abrasive material and the object to be polished are placed in this cylinder, and a rotary drum is used. When the cylinder is rotated, the abrasive material inside the cylinder is pressed against the inner wall of the cylinder by centrifugal force, forming a slightly uniform layer of abrasive material. As a result, a polishing layer is formed in which the curved surface of the inner wall of the cylinder is the same as the curvature of the inner wall of the cylinder, that is, the same as the curvature of the curved surface of the processed product. ), a curved surface with a desired curvature is formed on the bottom surface of the object to be polished. When the cylinder is tilted at a predetermined angle of 7 degrees or less, preferably 4 degrees or less, with respect to the rotation axis of the rotary drum, the abrasive material in the cylinder and the object to be polished slide, and one end of the cylinder and the other end of the cylinder slide. Polished by reciprocating flow between both ends while gradually sliding from the ball A to the ball B along the circumferential surface of the ball in a continuous spherical shape between the other end, No matter which direction the object to be polished faces, the vertical axis
A curved surface having the same required curvature is formed uniformly along the horizontal axis, Y axis, and X axis.

型シリンダーで前出の研磨方法より仕上条件が良い事が
研磨結果で確認された。The above-mentioned polishing device was developed as a dedicated polishing device for flat bar-shaped (Fig. 1 (1)) and strip-shaped vibrators, but it can also be used for polishing spindle disk-shaped, regular square, and rectangular disk-shaped vibrators using the spherical continuous type. The polishing results confirmed that the cylinder had better finishing conditions than the previously mentioned polishing method.

の破損の発生率が大きい。又傾斜角ゼロの場合は流動が
ない為、均一な研磨ができない。In addition, if the mounting angle of the cylinder with respect to the rotating shaft of the rotary drum is large, the reciprocating flow will be intense and the chances of damage to the polished object will be high. Also, if the angle of inclination is zero, there is no flow, so uniform polishing cannot be achieved.
シリンダーの傾斜角度と曲率に対する球の極との寸法が
密接に関連している事が実験の結果判明した。As a result of experiments, it was found that the inclination angle of the cylinder and the dimension of the sphere's pole relative to the curvature are closely related.

と思われる。When polishing vibrators using a barrel polishing machine equipped with the above-mentioned spherical continuous polishing cylinder, it is possible to increase the productivity of vibrators by improving the polishing finish characteristics, increasing the efficiency of polishing work, and increasing the efficiency of polishing capacity. It is believed that this will greatly contribute to the

研磨面が研磨される割合をほぼ半々にする事ができる。The polishing device according to the present invention differs from the conventional polishing device in that the central axis of the cylinder holder is inclined at a predetermined angle with respect to its rotation axis, and the cylinder attached to the cylinder holder is of a spherical continuous type, and the entire inner peripheral surface thereof is is formed to have the same curvature as the required processing curved surface of the object to be polished, and the rotary drum is rotated. If the motor is operated intermittently with a predetermined operation and stop, when the motor stops, that is, when the rotary drum stops rotating, the object to be polished in the cylinder will be released from the centrifugal force and will be reversed. If this continues for a predetermined period of time, the rate at which both wave polished surfaces of the flat object to be polished can be polished can be approximately equal to and equal to half.

両面の均一研磨の確率を高める。Furthermore, in addition to the above, when the rotary drum is stopped and the cylinder receiver and the polishing cylinder attached to the cylinder receiver are rotated by a drive device (geared motor) that rotates the cylinder receiver, the object to be polished is evenly agitated and the object to be polished is Increases the probability of uniform polishing on both sides.

両側より平均に研磨され被研磨体の中心のずれの発生を
防ぐ事ができ、研磨仕上りが良好である。In addition, by alternately operating the rotary drum in intermittent forward and reverse rotation, polishing of the object to be polished can be done in one direction only.
Polishing is done evenly from both sides, preventing the center of the polished object from shifting, resulting in a good polishing finish.
