Detailed Description
The utility model is described in further detail below with reference to the accompanying drawings.
As shown in fig. 2 to 5, the balance pressing device for an aluminum alloy metro car coupler seat of the present utility model comprises: the device comprises a supporting seat 1, a compression bolt 2, a compression arm 3, a lateral jacking mechanism 4 and a force balancing mechanism 5, wherein a limiting block 1-1 is fixedly connected to the front end of the upper portion of the supporting seat 1, the limiting block 1-1 is used for limiting the side wall of a car coupler seat 6, and the height of the supporting seat 1 is smaller than that of the car coupler seat 6. The lower part of the compression bolt 2 passes through the compression arm 3 and is in threaded connection with the top end of the supporting seat 1, and the upper part of the compression bolt 2 is pressed at the middle part of the compression arm 3; the lateral tightening mechanism 4 is a screw rod structure formed by a screw nut and a screw rod which are in threaded connection, the screw nut is fixedly connected to the side wall of the supporting seat 1, and the screw rod is used for tightening the side wall of the coupler seat 6. The force balancing mechanism 5 includes: the base sleeve 5-1, the bolt 5-2 and the spanner 5-3, base sleeve 5-1 and supporting seat 1 parallel arrangement, the bottom of base sleeve 5-1 and the bottom of supporting seat 1 all link firmly on same base, and force balance mechanism 5 is located the below of compressing tightly arm 3, and the inner wall of base sleeve 5-1 is equipped with the screw thread, and the lower part of bolt 5-2 inserts in the base sleeve 5-1 and with its threaded connection, and spanner 5-3 links firmly on bolt 5-2 upper portion lateral wall, and bolt 5-2 is used for upwards pushing up the rear end of compressing tightly arm 3.
