Embodiment Construction

[0025] Such as Figure 1-6 As shown, the present invention includes a sealed container and an air inlet 5 communicating with the sealed container. The sealed container includes a rotating shaft fin 61 fixed on a rotating shaft 6. A reset member for resetting the rotating shaft 6 is arranged on the rotating shaft 6. The rotating shaft 6 The upper part is also connected with a rotating disk 7 through a one-way gap rotating member.

[0026] The present invention enters the air into the sealed container through the air inlet 5, and the air pressure in the sealed container rises, pushing the rotating shaft fin 61 to rotate, thereby driving the rotating shaft 6 to rotate. 7 does not rotate. When the airtight container is not fed in, the gas in the airtight container leaks and the air pressure drops, and the fins 61 of the rotating shaft return to the initial position under the action of the reset member, thereby driving the turntable 7 to rotate. The rotation angle of the turntabl...

Abstract

The invention relates to a device and method for changing the rotating angle, in particular to a pneumatic rotating device and a method for changing the rotating angle. The pneumatic rotating device includes a sealing container and an air inlet communicating with the sealing container; the sealing container comprises a rotating shaft fin fixed on a rotating shaft, and a reset piece used for resetting the rotating shaft is arranged on the rotating shaft; and the rotating shaft is further connected with a turntable through a one-way intermittent rotating piece. According to the pneumatic rotating device, gas filling and releasing are combined with the one-way intermittent rotating piece, the qualitative and quantitative control over the rotating angle of the device is achieved so as to adjust the frequency of the material supply and the spacing of the material storage or to supply the transmission of materials of different sizes, the positioning accuracy is high, and the materials can beused for stamping and the like.

Description

technical field [0001] The invention belongs to a device and method for changing the rotation angle, in particular to a pneumatic rotation device and a method for changing the rotation angle. Background technique [0002] In production practice, it is often necessary to have quantitative or qualitative control over the angle of rotation. For example, when the high molecular polyethylene fiber precursor is stretched, it needs to be placed in a specific way; or when the workpiece is processed, multiple surfaces need to be processed. In addition to adjusting the position of the processing equipment, the position of the workpiece can also be adjusted. [0003] For example, the Chinese patent application No. 98201965.3 discloses a rotation angle control mechanism for multi-jaw fixtures, which consists of a base, an index wheel and a drive rod. The base is provided with a pivot hole for the index wheel and a pivot hole for the drive rod. The outer circumference of the indexing wh...
