Description

キャリア4はワークWの仕上げ寸法よりも薄い薄板状の円板であって、ワークWが着脱自在に装着される装着孔9を略同心状に有する。キャリア4は図1〜図4に示すように、その外周に略同心状に配置されたキャリアリング5と、キャリアリング5内に固定され且つキャリア4の外周をキャリアリング5側に押える押えリング10とにより支持されている。キャリアリング5は円筒面状に形成された外周面12をキャリア4の回転中心に対して略同心状に有し、また軸心方向の両側の端面は静圧パッド1の静圧面の外周側の段部11と隙間をおいて対向している。キャリア4、キャリアリング、押えリング10によりキャリア手段7が構成されている。 The carrier 4 is a thin plate-like disk that is thinner than the finished dimensions of the workpiece W, and has mounting holes 9 in which the workpiece W is detachably mounted. As shown in FIGS. 1 to 4, the carrier 4 has a carrier ring 5 disposed substantially concentrically on the outer periphery thereof, and a holding ring 10 that is fixed in the carrier ring 5 and presses the outer periphery of the carrier 4 toward the carrier ring 5. And is supported by. The carrier ring 5 has a cylindrical outer peripheral surface 12 formed concentrically with respect to the center of rotation of the carrier 4, and both end surfaces in the axial direction are on the outer peripheral side of the static pressure surface of the static pressure pad 1. It faces the step 11 with a gap. The carrier 4, the carrier ring, and the presser ring 10 constitute carrier means 7 .

固定手段16aは静圧キャリアガイド6aの一方のピン孔21に圧入された固定ピン39と、固定ピン39が嵌脱するピン孔38bを有し且つ支持アーム34の側面に着脱自在に装着された固定ブラケット38とを有する。固定ブラケット38は基部側の固定ボルト40により支持アーム34に着脱自在に枢着され、その長孔38aを貫通して支持アーム34側に螺合する調整ボルト41により固定ボルト40廻りに角度調整可能である。ピン孔38bは固定ブラケット38の先端部に設けられ、このピン孔38b固定ピン39が嵌脱自在に嵌合している。規制手段17aは静圧キャリアガイド6aの他方のピン孔21と、収容部35を貫通してピン孔21に挿通された規制ピン42とにより構成され、規制ピン42とピン孔21との間にフローティング範囲に相当する隙間が設けられている。 The fixing means 16a has a fixing pin 39 press-fitted into one pin hole 21 of the static pressure carrier guide 6a, and a pin hole 38b into which the fixing pin 39 fits and is detachably mounted on the side surface of the support arm 34. And a fixing bracket 38. The fixing bracket 38 is detachably pivotally attached to the support arm 34 by a fixing bolt 40 on the base side, and the angle of the fixing bracket 38 can be adjusted around the fixing bolt 40 by an adjustment bolt 41 that passes through the long hole 38a and is screwed to the support arm 34 side. It is. The pin hole 38b is provided at the tip of the fixed bracket 38, and the fixed pin 39 is fitted in the pin hole 38b so as to be detachable. The restricting means 17 a is configured by the other pin hole 21 of the static pressure carrier guide 6 a and a restricting pin 42 that passes through the accommodating portion 35 and is inserted into the pin hole 21, and between the restricting pin 42 and the pin hole 21. A gap corresponding to the floating range is provided.

静圧キャリアガイド6bを固定するときの固定手段16bは、図3、図5、図10に示すように、係合ピン55と固定ブラケット50の固定孔53とにより構成され、係合ピン55を固定孔53に挿入することにより、静圧キャリアガイド6bを固定するようになっている。 As shown in FIGS. 3, 5, and 10, the fixing means 16 b for fixing the static pressure carrier guide 6 b is configured by the engaging pin 55 and the fixing hole 53 of the fixing bracket 50. The static pressure carrier guide 6b is fixed by being inserted into the fixing hole 53 .

またキャリアリング5の外周に略四等配に配置された各静圧キャリアガイド6a,6bの内、キャリアリング5の直径方向の両側に配置された静圧キャリアガイド6a,6bは、図に示すように、静圧流体の圧力及び流量が十分大である同一回路27に接続されているため、静圧キャリアガイド6a,6bの静圧面22とキャリアリング5の外周面12との間の隙間が変動したときには、同一回路27内の圧力を揃えようとする力が働き、キャリアリング5が定位置を保とうとするため、安定した回転精度を得ることができる。 The respective hydrostatic carrier guides 6a disposed substantially square uniformly arranged on the outer periphery of the carrier ring 5, among 6b, hydrostatic carrier guide 6a that is disposed on both sides of the diameter direction of the carrier ring 5, 6b are in FIG. 9 As shown, the gap between the static pressure surface 22 of the static pressure carrier guides 6a and 6b and the outer peripheral surface 12 of the carrier ring 5 is connected to the same circuit 27 where the pressure and flow rate of the static pressure fluid are sufficiently large. When the pressure fluctuates, a force that tries to equalize the pressure in the same circuit 27 works and the carrier ring 5 tries to maintain a fixed position, so that stable rotation accuracy can be obtained.

図3、図5、図6、図10は各静圧キャリアガイド6a,6bを固定した状態を示す。上側の静圧キャリアガイド6aを固定する場合には、図3、図6に示すように静圧キャリアガイド6aの固定ピン39を固定ブラケット38のピン孔38bに挿入し、また固定ブラケット38を固定ボルト40で支持アーム34に枢着する。この状態で固定ボルト40廻りに長孔38aの範囲内で固定ブラケット38を回動させると、静圧キャリアガイド6aがフローティング軸15a廻りに回動して、フローティング軸15aの両側で静圧キャリアガイド6aの静圧面22とキャリアリング5の外周面12との隙間が変化するので、フローティング軸15aの両側でその隙間が略均等になった位置で調整ボルト41を締め付けて固定すれば良い。 3, FIG. 5, FIG. 6 , and FIG. 10 show a state in which the static pressure carrier guides 6a and 6b are fixed. When the upper static pressure carrier guide 6a is fixed, the fixing pin 39 of the static pressure carrier guide 6a is inserted into the pin hole 38b of the fixing bracket 38 and the fixing bracket 38 is fixed as shown in FIGS. The bolt 40 is pivotally attached to the support arm 34. In this state, when the fixing bracket 38 is rotated around the fixing bolt 40 within the range of the long hole 38a, the static pressure carrier guide 6a is rotated around the floating shaft 15a, and the static pressure carrier guide is formed on both sides of the floating shaft 15a. Since the gap between the static pressure surface 22 of 6a and the outer peripheral surface 12 of the carrier ring 5 changes, the adjustment bolt 41 may be fastened and fixed at the positions where the gap is substantially uniform on both sides of the floating shaft 15a.
