Swing type pneumatic clamping reaction arm mechanism

Abstract

The invention discloses an oscillating type pneumatic clamping reverse force arm mechanism. The oscillating type pneumatic clamping reverse force arm mechanism comprises a rack (2) provided with a roller bed (1), and a tray (3) for conveying workpieces is arranged on the roller bed (1). The oscillating type pneumatic clamping reverse force arm mechanism is characterized in that a supporting frame (4) is arranged on the rack (2), an oscillating bar (6) with an oscillating handle (5) is rotationally supported by the supporting frame (4), the oscillating bar (6) can drive a sector-shaped disk (7) to rotate, an air locking device (8) matched with the sector-shaped disk (7) is arranged, a reverse force arm screwing mechanism (9) which is arranged on the supporting frame (4) and can axially float can rotate along with the oscillating bar (6) at the same time, a pushing handle (10) is arranged at the tail end of the reverse force arm screwing mechanism (9), at least two positioning shafts (11) are arranged at the front end of the reverse force arm screwing mechanism (9), a working handle (12) is arranged on the supporting frame (4), and a button (13) capable of controlling the work of the reverse force arm screwing mechanism (9) is arranged at the top end of the working handle (12).

Description

technical field [0001] The invention relates to a reaction arm tightening mechanism, in particular to a swing type pneumatic clamping reaction arm mechanism. Background technique [0002] When installing some workpieces, it is necessary to use the reaction arm mechanism to tighten the bolts on the workpiece to realize the connection between the workpieces. The traditional reaction arm mechanism requires the operator to hold the handle on it to move, so that the reaction The tightening mechanism on the moment arm mechanism moves to the bolt of the workpiece for tightening operation. The problem with this method is that it is cumbersome for the operator to move the reaction arm mechanism and position it accurately with the bolt, and it is impossible to achieve fast and accurate positioning operation, which delays the production efficiency. And in the tightening process, it is necessary for the operator to hold the reaction arm mechanism to bear a part of the reaction arm, whi...

Problems solved by technology

The problem with this method is that it is troublesome for the operator to move the reaction arm mechanism and position it accurately with the bolt, and it is impossible to achieve fast and accurate positioning operation, which delays the production efficiency

Moreover, during the tightening process, the operator needs to hold the reaction arm mechanism to bear a part of the reaction arm, which sometimes cannot be achieved only by the strength of the operator.
