In order to achieve the above object, the following technical scheme is adopted:

The utility model provides a rapier loom weft insertion pendulum rod assembly positioner, it includes weft insertion box, weft insertion pendulum rod, the pendulum rod locating plate, the gauge post, set screw, the backing pin, the locating pin, the bearing frame, a bearing, the gasket, the bolt, adjust the gasket, weft insertion cross axle, weft insertion pendulum rod sets up on weft insertion cross axle, weft insertion cross axle both ends set up bearing and bearing frame respectively, the bearing frame passes through the bolt and sets up on weft insertion box with the gasket, be provided with the adjusting gasket between bearing frame and the weft insertion box, the backing pin sets up on the pendulum rod locating plate, the pendulum rod locating plate passes through the gauge post, the locating pin sets up on weft insertion box, the pendulum rod locating plate passes through set screw and sets up on weft insertion box, the axle setting of weft insertion pendulum rod is on the backing pin, the axle and the A face of pendulum rod locating plate just contact.

As a further improvement of the invention, the two ends of the swing rod positioning plate are provided with pin holes, the middle is provided with a positioning hole, the swing rod positioning plate is arranged on the weft insertion box body through the pin holes and the gauge columns by the positioning pins, and the swing rod positioning plate is fixedly arranged on the weft insertion box body through the positioning holes by the fixing screws.

As a further improvement of the invention, the axis of the weft insertion swing rod is phi 45.

Compared with the prior art, the invention has the following beneficial effects: 1. the front and back of the weft insertion swing rod are ensured to be positioned at the set position, so that the four-bar linkage operation is flexible in the whole space, the operation performance of the whole machine is improved, the reliability is improved, and the weaving quality is improved; 2. the assembly efficiency of the loom is improved, the working hours are less, and the time and the cost are saved; 3. the assembly process is simplified, and the assembly efficiency is improved; 3. the bearing is not easy to wear, and the service life of the bearing is prolonged; the design scheme of the invention solves the positioning problem in the assembly of the weft insertion swing rod of the rapier loom.
