Description

Technical Field

[0001] The utility model relates to the technical field of loom accessories, in particular to a rocker shaft connecting seat structure which is convenient for assembly. Background Art

[0002] The existing driving transmission device of the air jet loom includes a crankshaft, a rocking shaft, a center shaft, a serration shaft and a driving motor. The crankshaft is connected to the rocking shaft through a handgrip and a swing arm. When the crankshaft rotates, the rocking shaft is driven to swing through the swing arm, and then the rocking shaft drives the sley of the air jet loom to swing to beat the weft. The movement form of the rocking shaft is swinging, and the direction of its torque is constantly changing. The rocking shaft swinging component is also a component with extremely asymmetric moment of inertia. The moment of inertia of the swinging component is concentrated on one side of the center line of the rocking shaft. If this continues for a long time, it will cause the rocking shaft to bend eccentrically, causing the rocking shaft to swing unbalanced, affecting the beating of the loom. Therefore, it is necessary to disassemble and replace the rocking shaft in time, but the rocking shaft connecting seat is usually an integrated structure that is inconvenient to disassemble and assemble, affecting the working efficiency of the loom.

[0024] Working principle:

[0025] In the present invention, the connecting rod 5 and the fixed seat 2 can be unlocked by the locking bolt 6, and the movable seat 3 can be pulled in the vertical direction, and the movable seat 3 can be pulled upward to make the movable seat 3 separate from the fixed seat 2 in the vertical direction. In the process of pulling upward, the extrusion block 8 installed on the sliding block 7 contacts and abuts against the unlocking block 15. Through the effect of the inclined extrusion surface, the sliding block 7 slides inward in the horizontal slide groove 11 until the sliding block 7 is completely retracted into the horizontal slide groove 11. The sliding rack 82 can mesh with the locking gear 9 in the rotating groove 12, and can drive the locking rod 10 to slide backward in the telescopic groove 13 through threaded cooperation until the locking rod 10 is separated from the locking hole 16 and hidden in the telescopic groove 13. At this time, the connecting rod 5 and the sliding block 7 are unlocked. The connecting rod 5 can be rotated on the sliding block 7. Rotating the connecting rod 5 can make the movable seat 3 separate from the fixed seat 2 in the horizontal direction and expose the internal connecting bearing 1, so as to realize the rapid disassembly and assembly of the rocking shaft. After the assembly is completed, the connecting rod 5 is rotated to reset the movable seat 3 in the horizontal direction, and the connecting rod 5 is slid vertically downward. During the downward sliding process, the extrusion block 8 will gradually separate from the unlocking block 15 and lose the extrusion support. Under the action of the reset torsion spring 14, the locking gear 9 rotates in the opposite direction, and the locking rod 10 will extend forward into the locking hole 16 to form a rotation lock, until the connecting rod 5 slides to the lower end of the sliding groove 4, and the locking bolt 6 is used to form a sliding lock between the connecting rod 5 and the fixed seat 2, so as to complete the rapid assembly of the rocking shaft and the connecting seat body.
