Problems solved by technology
However, in such a trunnion support structure, the clamping block fits with the mounting groove of the trunnion bracket and the positioning groove of the cylinder at the same time. During assembly, the processing accuracy of the mounting groove of the trunnion bracket and the positioning groove of the cylinder is high, which improves the processing efficiency. cost
The clamping block needs to be inserted into the installation groove after the preliminary positioning of the trunnion bracket and the cylinder, and the installation process is also relatively inconvenient

The invention discloses an air cylinder trunnion supporting attachment. The air cylinder trunnion supporting attachment comprises a cylinder body and trunnion supports which are symmetrically arrangedon the two sides of the cylinder body, positioning grooves matched the cylinder body in width are formed in the inner sides of the trunnion supports, trunnions are arranged on the outer sides of thetrunnion supports, column grooves are formed in the two side walls of each positioning groove correspondingly, clamping columns which are parallel to the cylinder body in the axial direction are arranged in the column grooves, gaskets which are rotationally connected with the trunnion supports are arranged at the ends of the clamping columns, and protrusions which are attached to the clamping columns are arranged on the side face of the cylinder body, and locking screws which act on the clamping columns to enable the clamping columns to be fastened to the protrusions are arranged on the trunnion supports. The air cylinder trunnion supporting attachment aims to achieve the effects of reducing the machining cost and improving the installation convenience.
Description
technical field The invention belongs to the field of pneumatic components, in particular to a cylinder trunnion supporting accessory. Background technique At present, most of the trunnion brackets of the cylinder are fixed in an embracing manner, that is, symmetrical brackets are used on both sides of the cylinder body of the cylinder, and fastened by fixing bolts, such as Chinese patent announcement number: CN201412413, authorized announcement date February 24, 2010 On the 1st, a movable central trunnion was disclosed, comprising a main body, four pressing blocks, and screws. The main body is provided with small shafts up and down, and the main body and the four pressing blocks are fastened by screws. However, such a fixed structure is easily loosened by the impact of the repeated movement of the cylinder piston, causing the trunnion bracket to slide in the axial direction of the cylinder body, the entire cylinder moves, and the action stroke of the piston rod becomes inva...
