Description

本発明は、リニアアクチュエータに関し、特に、オートロック機能付きリニアアクチュエータ用組付け装置に関するものである。   The present invention relates to a linear actuator, and more particularly to an assembly device for a linear actuator with an auto-lock function.

まず、図１を参照する。リニアアクチュエータの運動は、モータ１０が動力を出力し、この動力は、互いに垂直に噛合うウォーム１１とウォーム歯車１２とを経由し、ねじ軸１３に伝えられ、ねじ軸１３が回転し、このとき、ねじ軸１３に螺合するブッシュ１４がねじ軸１３の軸方向に沿って変位し、これにより、ブッシュ１４と同軸に連接する内管１５を押えることができ、ブッシュ１４によるリニア押え力が内管１５を経由して外部に与えられ、且つウォーム歯車１２に締結されるオートロック用バネ１６によりねじ軸１３の回動が制御される。   First, refer to FIG. As for the movement of the linear actuator, the motor 10 outputs power, and this power is transmitted to the screw shaft 13 via the worm 11 and the worm gear 12 that are vertically engaged with each other, and the screw shaft 13 rotates. The bush 14 that is screwed to the screw shaft 13 is displaced along the axial direction of the screw shaft 13, whereby the inner tube 15 that is coaxially connected to the bush 14 can be pressed, and the linear pressing force by the bush 14 is increased. The rotation of the screw shaft 13 is controlled by an auto-locking spring 16 which is given to the outside via the pipe 15 and fastened to the worm gear 12.

上記の伝動装置を適切に組付けるために、図２及び図３に示すように、特許文献１の米国特許第７０６６０４１号及び特許文献２の欧州特許第１３２２８７６号のアクチュエータ用組付け装置２０が提案された。アクチュエータ用組付け装置２０は、ほぼチューブ形状を呈するギアボックス２１に伝動装置の各部材が組み付けられ、ねじ軸１３のシャフトの一端に設けられ二つの部材を組合って構成されるリア固定台２２により軸受１７にねじ軸１３を固定する。そうすると、ねじ軸１３のその軸方向への変位ができなくなり、二つのハーフケース２３、２４を上下に組合わせることにより、ギアボックス２１とリア固定台２２を連接することができる。   In order to properly assemble the above transmission device, as shown in FIG. 2 and FIG. 3, the actuator assembly device 20 of US Pat. No. 6,066,041 of Patent Literature 1 and European Patent No. 1,228,762 of Patent Literature 2 is proposed. It was done. The actuator assembly device 20 includes a rear fixing base 22 configured by combining each member of the transmission device with one end of the shaft of the screw shaft 13 in which each member of the transmission device is assembled in a gear box 21 having a substantially tube shape. Thus, the screw shaft 13 is fixed to the bearing 17. Then, the screw shaft 13 cannot be displaced in the axial direction, and the gear box 21 and the rear fixing base 22 can be connected by combining the two half cases 23 and 24 up and down.

米国特許第７０６６０４１号明細書US Pat. No. 6,066,041 欧州特許第１３２２８７号明細書European Patent No. 132287

しかしながら、これは次のような欠点があった。
（１）リア固定台２２は、更に、リニアアクチュエータ全体と外部の部材を連結するためのものとされ、しかし、従来の二つの部材を組合って構成されるリア固定台２２の応力を受ける強度が不足であり、リア固定台２２は損壊し易い。 However, this has the following drawbacks.
(1) The rear fixing base 22 is further used for connecting the entire linear actuator and an external member, but the strength of the rear fixing base 22 configured by combining two conventional members is subjected to stress. Is insufficient, and the rear fixing base 22 is easily damaged.

（２）二つのハーフケース２３、２４を結合してケースを構成する技術はよく見られるが、二つのハーフケース２３、２４の結合面がモータ１０の軸方向と垂直になる場合には、製造が不便になり、すなわち、組付時の操作スペースが規制され、且つ超音波溶接により二つのハーフケースを溶接するときに、重力により二つのハーフケースを緊密に接触することができず、溶接による結合の品質が低下する。 (2) A technique of combining two half cases 23 and 24 to form a case is often seen. However, if the connecting surface of the two half cases 23 and 24 is perpendicular to the axial direction of the motor 10, manufacture is possible. Is inconvenient, that is, the operation space during assembly is restricted, and when the two half cases are welded by ultrasonic welding, the two half cases cannot be brought into close contact with each other due to gravity. The quality of the bond is reduced.

（３）重力により二つのハーフケースを緊密に接触することができない問題を解決するために、ヤットコ２５により外管１８とギアボックス２１を結合する方法が採用されるが、構成が複雑になり、製造プロセスが複雑化になり、製造コストが増加する。 (3) In order to solve the problem that the two half cases cannot be brought into close contact with each other due to gravity, a method of joining the outer tube 18 and the gear box 21 with the Yatco 25 is adopted, but the configuration becomes complicated. The manufacturing process becomes complicated and the manufacturing cost increases.

本発明の主な目的は、リニアアクチュエータ全体と外部の部材の結合構造の強度が増加し、リニアアクチュエータの寿命が更に長く延び、超音波溶接により二つのハーフケースを溶接するときに、重力だけを利用すると、二つのハーフケースを緊密に接触することができ、固定子を利用せずに外管とギアボックスを結合することができ、部品の点数が減少し、製造コストを減少することができるオートロック機能付きリニアアクチュエータ用組付け装置を提供することにある。   The main object of the present invention is to increase the strength of the combined structure of the entire linear actuator and the external member, further extend the life of the linear actuator, and reduce only the gravity when welding two half cases by ultrasonic welding. When used, the two half cases can be brought into close contact with each other, the outer tube and the gear box can be coupled without using the stator, the number of parts can be reduced, and the manufacturing cost can be reduced. An object is to provide an assembly device for a linear actuator with an auto-lock function.
