Five, the specific embodiment
Combine accompanying drawing that the utility model is explained further details at present:
A kind of bindiny mechanism that is applied to air-jet loom underneath type opening; Its structure is to be integral through rivet by connection-peg 1 and middle brace 2, left and right sides brace 3; Middle brace 2, left and right sides brace 3 are provided with 60 ° of flange; In the special bearing 10 that inner ring has 60 ° of taper holes is housed in the swing arm 4, left swing arm 5, right swing arm 6, through a pair of special bolt nut 11 that has 60 ° of conical surfaces in swing arm 4, left swing arm 5, right swing arm 6 link into an integrated entity with connection-peg 1.Connection-peg 1 produces certain elasticity and hardness through heat treatment, and two connectors of connection-peg 1 are pre-large post-small, have 4.6 ° tapering, when not stressing, can insert left connecting rod 7 and right connecting rod 8 inner chambers, and there is the emboss pit of special circular arc both sides.Left side connecting rod 7 suppresses the circular groove that matches with joint 1 with side, right connecting rod 8 two ends on punch press through particular manufacturing craft.
Link into an integrated entity through rivet, bolt and nut 11 on connection-peg 1, middle brace 2, left and right sides brace 3, middle swing arm 4, left swing arm 5, the right swing arm 6; Middle swing arm 4, left swing arm 5, right swing arm 6 can swing through bearing 10, and connection-peg 1 and middle brace 2, left and right sides brace 3 riveted joint backs are more than the 150kg at P to tensile failure intensity.
Connection-peg 1 inserts left connecting rod 7 and right connecting rod 8 one ends; With the inner hexagon spanner M5 screw special 9 that turns clockwise; Shore two connectors of connection-peg 1, connection-peg 1 produces strain and opens, the mutual interlock of convex-concave circular arc on connection-peg 1 and left connecting rod 7 and the right connecting rod 8; Like this, left connecting rod 7 and right connecting rod 8 just with middle swing arm 4, left swing arm 5, right swing arm 6 firm correct linking together.This connected mode is more than the 100kg at P to tensile failure intensity.When dismantling left connecting rod 7 with right connecting rod 8; Be rotated counterclockwise M5 screw special 9 with inner hexagon spanner; M5 screw special 9 heads do not contact with the bottom connector disengaging of U-shaped connection-peg 1; Connection-peg 1 returns to nature, takes down M5 screw special 9, and left connecting rod 7 just can withdraw from from connection-peg 1 with right connecting rod 8 easily.
The utility model is the improvement to the opening linkage of existing air-jet loom; Mainly be to the existing in prior technology syndeton is heavy, inertia is big, power consumption is high, can not realize high-speed motion; Provide a kind of positive cam shedding rational in infrastructure to use linkage; Especially connecting rod is down linking into an integrated entity with swing arm of secure in working order, can combine dismounting from swing arm easily again when transportation or replacing.
The fundamental diagram of the utility model.Left side connecting rod 7 is connected with shedding motion through special carrier with right connecting rod 8 one ends; The size of opening amount is adjusted through moving the position of chuck on the opening arm of shedding motion; Easy to operate, left connecting rod 7 and right connecting rod 8 other ends are connected with joint on being fixed on the standard heald frame with having the hook of fastening system.This opening linkage adopts underneath type installation, quadric chain, and through rigidity square steel connection opening device and heald frame, front and back two hooks are synchronized with the movement, and guarantee that heald frame moves up and down by cam curve is well-regulated.The special long and short connecting rod of cold drawn section steel manufacture, cold drawn shaped steel has enough intensity, rigidity and impact resistance, and appearance and size is smooth, and flatness, perpendicularity all have specific (special) requirements.Connection-peg 1 with the catenation principle of middle swing arm 4, left swing arm 5, right swing arm 6 is: special-purpose connection-peg 1 and middle brace 2, left and right sides brace 3 are integral through rivet; Middle brace 2, left and right sides brace 3 are provided with 60 ° of flange; In the special bearing 10 that inner ring has 60 ° of taper holes is housed in the swing arm 4, left swing arm 5, right swing arm 6, through a pair of special bolt nut 11 that has 60 ° of conical surfaces in swing arm 4, left swing arm 5, right swing arm 6 link into an integrated entity with connection-peg 1.Middle swing arm 4, left swing arm 5, right swing arm 6 can swing through bearing 10, and connection-peg 1 and middle brace 2, left and right sides brace 3 riveted joint backs are more than the 150kg at P to tensile failure intensity, satisfy the job requirement of linkage fully.
Connection-peg 1 with the catenation principle of right connecting rod 8 is: connection-peg 1 inserts right connecting rod 8 one ends, and M5 screw special 9 is shored connection-peg 1, and connection-peg 1 produces strain and opens, and the mutual interlock of convex-concave circular arc on connection-peg 1 and the right connecting rod 8 links together.This connected mode is more than the 100kg at P to tensile failure intensity.During dismounting right connecting rod 8, take down M5 screw special 9, connection-peg 1 returns to nature, and right connecting rod 8 just can withdraw from from connection-peg 1 easily.
