機構の精度に多く依存する。The accuracy and stability of the moving dimensions of moving carriages such as tables, which are widely used in various industries, greatly depend on the accuracy of the feeding mechanism.
従来上記送り機構は、第１３図と第１４図に示すような

式がある。Conventionally, the above-mentioned feeding mechanism includes a direct mounting type as shown in FIGS. 13 and 14, and a leaf spring type as shown in FIGS. 15 and 16.

ＮＨ２を１枚の板バネＦを介して連結している。In the direct mounting type feeding mechanism, a nut N1 is directly fixed to the moving carriage C1 via a nut holder NH1, and a feed screw S1 is screwed onto the nut N1. Further, in the leaf spring type feeding mechanism, the nut boulder NH2 is connected to the moving carriage C2 via one leaf spring F.

をバラツキの多い不安定なものにしている点に注目した
。- Problem to be solved by Akira By the way, the present inventor has discovered that the nut N1. The eccentric movement of N2 (see Figure 17) results in the periodic application of harmful stress to the stable moving carriages C1 and C2, making the movement of the moving carriages C1 and C2 variable and unstable. I paid attention to the fact that
ナツトの振れによる移動キャリッジの揺動に伴なう影響
を、工作機械について例示して説明する。The influence of the swinging of the moving carriage due to the swinging of the nut will be explained using a machine tool as an example.
第１８図から第２１図に示すように、直っけ式のもので

２７０’ 、３６０”と回転移動する（各々Ｑ印から・
印に移動）と、移動キトリッジＣ１は上下方向に揺動す
る。As shown in Figs. 18 to 21, in the case of the straight type, the runout P of the nut is 90°, 180° counterclockwise,
Rotate 270' and 360'' (from the Q mark respectively)
mark), the movable kittridge C1 swings in the vertical direction.

に対してｄＱ＝Ｈ−ｔａｎｅ
の関係をもって発生する。That is, as shown in FIG. 22, the moving carriage C1
The swing angle θ causes a feed error d9, and this error dQ is determined by the height H from the center of the feed screw s1 to the workpiece processing part F.
This occurs with the relationship dQ=H-tane.

送りムラを生じながら移動する。On the other hand, in the leaf spring type, the deflection position of the nut N2 rotates as shown in FIGS. 23 to 26. A feed error d9 occurs due to the rotation angle α of the nut holder N)+2,
The error d9 is α X L/360=df! with respect to the lead L of the feed screw S2. This occurs due to the following relationship, and the moving carriage c2 moves with periodic uneven feeding.

ツトの振れによって、移動キャリッジの揺動を招き、移
動キャリッジの移動精度の低下がさけられない。Therefore, in both the straight type and the leaf spring type, the rotational movement of the nut holder that occurs when absorbing the swinging movement of the nut causes uneven feeding and backlash when the feed screw is reversed. Then, the vibration of the nut caused by the bending of the feed screw causes the moving carriage to swing, and a decrease in the movement accuracy of the moving carriage is unavoidable.

り機構を提供することを目的とする。This invention was made in order to solve the above problems, and while preventing the rotational movement of the nut boulder, the swinging circular movement of the nut is controlled in the vertical and horizontal directions with respect to the feeding direction of the moving carriage. To provide a feeding mechanism capable of accurately and stably feeding a moving carriage by converting the movement into a displacement movement, without causing unnecessary rocking of the moving carriage, and capable of uniform feeding and positioning.

In FIG. 8, the swing point of the nut 5 rotates counterclockwise by 90 degrees from the resting state in FIG. At the same time, the nut holder 12 moves in parallel in the E direction, and the swing point 5a is located above the horizontal reference line L1-11 and to the left of the vertical reference line L2-12.
