The connecting rod device is shown in Figures 1 and 2. The connecting rod 1 is a thin-walled rectangular tube. The connection between the connecting rod 1 and related parts adopts Special tapered screw 4, tapered nut 3 and special bearing 2, and taper holes are punched on the two opposite sides of the rectangular tube, and the tapered screw 4 and tapered nut 3 are respectively placed on one side of the tube wall In the tapered hole and screwed with each other, the special bearing 2 is supported on the tapered surface, and the inner cavity of the tapered surface forms the tapered hole.
织机在日常的维护修理或更换轴承2时，必须要拆除连杆装置，而拆除连杆装置的核心就是拆卸锥形螺钉4，但装配该螺钉时通常要用规定的力矩锁紧螺钉或加螺钉胶，因此拆卸螺钉所需的扭力大，更麻烦的是往往螺母跟着螺钉转动，无奈之下只有硬敲，常常敲坏连杆，增加维护成本。 When the loom is in daily maintenance or replacement of the bearing 2, the connecting rod device must be dismantled, and the core of dismantling the connecting rod device is to disassemble the tapered screw 4, but when assembling the screw, it is usually necessary to lock the screw or add Screw glue, so the torque required to disassemble the screw is large. What's more troublesome is that the nut often rotates with the screw. In desperation, there is only hard knocking, which often breaks the connecting rod and increases maintenance costs.

具体实施方式 detailed description
如图1，本发明的特殊螺钉拆卸器用于纺机开口机构的连杆上特殊螺钉4的拆卸。结合图2、3，特殊螺钉4的中心设有用于旋转该螺钉的六角孔41，特殊螺母3是可转动的设置在连杆1上，特殊螺钉4旋接在特殊螺母3上。本发明的拆卸器主要由拆卸座5和锁紧螺栓6及六角扳手7组成，拆卸座5设有可容纳部分连杆的凹槽51，该凹槽51相对的两侧槽壁52上分别设有螺孔53和通孔54，锁紧螺栓6旋接于螺孔53中，拆卸所述连杆上的所述特殊螺钉4时，将连杆上具有特殊螺钉4和特殊螺母3的一端置于凹槽51中，并使特殊螺母3和特殊螺钉4分别对着螺孔53和通孔54。旋动锁紧螺栓6使之通过相对螺孔53的运动，形成轴向移动，使锁紧螺栓6的端面A紧压在特殊螺母3的对应端面上。六角扳手7穿过通孔54伸入到特殊螺钉4的六角孔中，转动该六角扳手7，特殊螺钉跟随转动。由于锁紧螺栓6紧压在特殊螺母对应端面上的压紧力足够大，由此产生的摩擦力矩足以抵消特殊螺钉4转动有可能带动特殊螺母3跟随转动的力矩，从而使特殊螺母被固定，由此特殊螺钉4能相对特殊螺母3转动，使两者脱开螺旋连接，特殊螺钉4被卸下，从而可更换轴承2。 As shown in Fig. 1, the special screw remover of the present invention is used for the dismounting of the special screw 4 on the connecting rod of the opening mechanism of the spinning machine. 2 and 3, the center of the special screw 4 is provided with a hexagonal hole 41 for rotating the screw, the special nut 3 is rotatably arranged on the connecting rod 1, and the special screw 4 is screwed on the special nut 3. The remover of the present invention is mainly composed of a dismounting seat 5, a locking bolt 6 and a hexagonal wrench 7. The dismounting seat 5 is provided with a groove 51 that can accommodate part of the connecting rod. There are screw holes 53 and through holes 54, and the locking bolt 6 is screwed into the screw holes 53. When disassembling the special screw 4 on the connecting rod, place the end of the connecting rod with the special screw 4 and the special nut 3 in the groove 51, and make the special nut 3 and the special screw 4 face the screw hole 53 and the through hole 54 respectively. Rotate the locking bolt 6 to move relative to the screw hole 53 to form an axial movement, so that the end surface A of the locking bolt 6 is tightly pressed against the corresponding end surface of the special nut 3 . The hexagonal wrench 7 stretches into the hexagonal hole of the special screw 4 through the through hole 54, and the hexagonal wrench 7 is rotated, and the special screw follows the rotation. Because the locking bolt 6 is tightly pressed against the corresponding end surface of the special nut, the pressing force is large enough, and the resulting frictional moment is enough to offset the torque that the special screw 4 may drive the special nut 3 to follow the rotation, so that the special nut is fixed. Thus the special screw 4 can rotate relative to the special nut 3, so that the two are disengaged from the screw connection, and the special screw 4 is unloaded, so that the bearing 2 can be replaced.
为了增强形成凹槽51的两侧槽壁52的强度，凹槽51为U形凹槽，且为与槽的U形截面的垂直方向贯通，即为一个贯通的U形凹槽。而两侧槽壁上分别设置的螺孔53和通孔54为共轴线孔，以便该两孔的基孔可一次性加工。 In order to strengthen the strength of the groove walls 52 on both sides of the groove 51, the groove 51 is a U-shaped groove, and is vertical to the U-shaped cross section of the groove, that is, a through U-shaped groove. The screw holes 53 and the through holes 54 respectively provided on the groove walls on both sides are coaxial holes, so that the base holes of the two holes can be processed at one time.
同时为了保证锁紧螺栓对特殊螺母的推抵仅作用于特殊螺母上，锁紧螺栓紧压于特殊螺母一端的直径小于特殊螺母3对应端的直径。而为了方便地旋动锁紧螺栓6，将锁紧螺栓一端的外周侧61设置为六角面，或将锁紧螺栓6的中心孔62设置为六角孔，以便用对应扳手旋动锁紧螺栓6，使之向特殊螺母3一侧移动直至抵压在特殊螺母3上。 Simultaneously in order to ensure that the pushing of the locking bolt to the special nut only acts on the special nut, the diameter of the end of the locking bolt pressed against the special nut is smaller than the diameter of the corresponding end of the special nut 3 . And in order to turn the locking bolt 6 conveniently, the outer peripheral side 61 of one end of the locking bolt is set as a hexagonal surface, or the central hole 62 of the locking bolt 6 is set as a hexagonal hole, so that the locking bolt 6 can be rotated with a corresponding wrench. , so that it moves to the side of the special nut 3 until it is pressed against the special nut 3 .
再有，为了保证卸下的特殊螺钉4能较好地从连杆1上取出，通孔54的直径D大于特殊螺钉4最大处的直径。 Furthermore, in order to ensure that the removed special screw 4 can be taken out from the connecting rod 1 better, the diameter D of the through hole 54 is greater than the diameter of the largest part of the special screw 4 .
