Rotating shaft rotating angle limiting and adjusting mechanism

Abstract

The invention discloses a rotating shaft rotating angle limiting and adjusting mechanism. The rotating shaft rotating angle limiting and adjusting mechanism comprises a mechanism shaft, stop blocks, alimiting block, gears and worms, the two gears are arranged on the mechanism shaft in a penetrating mode and are in clearance fit with the mechanism shaft, the two worms are arranged on one side of the mechanism shaft and are correspondingly engaged with the two gears correspondingly, the two stop blocks are fixedly connected to the two gears correspondingly and rotate along with the gears, the limiting block is fixedly connected to the mechanism shaft and arranged between the two gears, two limiting arms which are arranged in a staggered mode are arranged on the limiting block, and the two stop blocks are located on a rotating path where the two limiting arms rotate around the axis of the mechanism shaft correspondingly. According to the rotating shaft rotating angle limiting and adjusting mechanism, position fixing of the stop blocks is achieved through worm and gear self-locking, the adjusting range is wide, use is flexible, the two stop blocks are arranged, the positions are independent, independent adjustment and control can be achieved, and the mechanism is reliable in operation and convenient to use.

Description

Technical field: [0001] The invention relates to a rotation angle limit adjustment mechanism of a rotation shaft. Background technique: [0002] When the mechanical reciprocating swing structure based on the rotating shaft as the center of rotation is in use, in order to prevent the swinging action from exceeding the limited range during the mechanical execution process, an adjustment mechanism for adjusting the rotation angle of the rotating shaft is often provided in the rotating direction of the rotating shaft. [0003] The existing adjustment structure generally fixes a limit block on the rotating shaft, and then sets two limit nails on the circumferential path of the limit block rotating along the axis of the shaft, and the two limit nails are correspondingly located on the circumferential path of the limit block. When the limit block rotates to the position of the limit nail, it is limited by the limit nail to avoid over-range movement during the reciprocating swing of...

Problems solved by technology

[0004] When this structure is in use, the position change of the limit nail is generally provided with several limit holes on the preset rotation path (that is, on the circumferential path of the above-mentioned limit block). When a certain position limit is required, Screw the limit screw into the hole at the corresponding position. This structure has poor flexibility and is inconvenient to adjust.
