The heald lifting device comprises a box body 1, a left moving rod 2, a right moving rod 2, an input shaft 3, a first transmission shaft 4, a second transmission shaft 5, an output shaft 6, a first bevel gear 7, a second bevel gear 8, a first transmission gear 9, a second transmission gear 10, a third transmission gear 11, a cam 12, a fixed block 13, a stop block 14, a fastening screw 15, a roller 16, an output gear 17, a left and right moving box 18, an opening heald frame 19 and a heald lifting box 20.
Detailed Description
The present invention will be described in further detail with reference to examples.
The embodiment provides a left and right moving box for a shedding heald frame, as shown in fig. 1 to 4, which comprises a box body 1 and left and right moving rods 2, wherein an input shaft 3, a transmission shaft I4, a transmission shaft II 5 and an output shaft 6 are rotatably connected to the box body 1, a bevel gear I7 is arranged at one end of the input shaft 3, which is positioned in the box body 1, a transmission gear I9 and a bevel gear II 8 meshed with the bevel gear I7 are fixed on the transmission shaft I4, a transmission gear II 10 and a transmission gear III 11 meshed with the transmission gear I9 are fixed on the transmission shaft II 5, a cam 12 and an output gear 17 meshed with the transmission gear II 10 are fixed on the output shaft 6, two fixed blocks 13 are arranged on the inner wall of the box body 1, linear bearings are arranged on the fixed blocks 13, the left and right moving rods 2 are connected with the fixed blocks 13 through the linear, the linear bearings provide guidance for the movement of the left and right moving rods 2, and ensure that the moving routes are on the same straight line. The stoppers 14 are two and located on both sides of the cam 12. The transmission ratio between the input shaft 3 and the output shaft 6 is 1:6, preferably, the bevel gear I7 and the bevel gear II 8 are the same in size, and the diameter ratios of the transmission gear I9, the transmission gear III 11, the transmission gear II 10 and the output gear 17 are 1:2:1:3 in sequence.
The top of the stop block 14 is provided with a mounting hole and a screw hole communicated with the mounting hole, a fastening screw 15 is connected with the screw hole in an internal thread manner, and the left and right moving rods 2 penetrate through the mounting hole and are fastened through the fastening screw 15; the lower part of the block 14 is provided with a mounting groove, and a roller 16 opposite to the cam 12 is arranged in the mounting groove. The stop block 14 and the left and right moving rods 2 are fixed through the fastening screw 15, so that the position of the stop block 14 on the left and right moving rods 2 can be conveniently adjusted according to requirements, and the left and right moving amplitude of the left and right moving rods 2 can be adjusted; by arranging the roller 16, the contact between the cam 12 and the stopper 14 is rolling friction, so that the friction force between the cam 12 and the stopper 14 is reduced, and the moving fluency of the left and right moving rods 2 is improved.
