33设置在卡板 3的尾部。 第一调整孔 31为两横向椭圆形槽或近似椭圆形槽 (也称腰 形槽), 以方便销座 7穿过, 另外在卡板 3尾部开一纵向腰形槽, 即第二调整孔 33, 用于偏心轮 9的安装。将压板 8顶住销座 7后靠紧固件 4及弹垫 5固定安装。安装后, 压板 8不直接跟卡板 3接触, 从而在偏心轮 9处于松开位置时, 卡板 3可以从对连接 件定位的位置滑出, 而不会影响卡板 3的左右滑行。 如图 3所示, 偏心轮 9包括转轴 91和与转轴 91连接的转轮 93。 转轮 93与转轴 91 的端部相连接。 转轴 91设置在压板 8中。 例如, 压板 8上设有轴套 83, 轴套 83 贯穿压板 8, 转轴 91设置在轴套 83中。 转轮 93设置在第二调整孔 33中。 第二调整 孔 33的口径与转轮 93的行程相配合。例如,第二调整孔 33为椭圆形孔或近似椭圆形 孔的长条形孔。 转轮 93具有锁紧位置和松开位置, 当处于锁紧位置时, 卡板 3位于销轴 2的凹槽 内, 以实现卡板 3对销轴 2的定位; 当处于松开位置时, 卡板 3从销轴 2的凹槽内脱 离, 从而能够实现对销轴 2的安装或者拆卸。 由于采用偏心轮 9, 偏心轮 9包括转轴 91和转轮 93, 转轴 91设置在压板 8中, 转轮 93设置在第二调整孔 33中,所以在保持转轴 91不离开压板 8的条件下,通过偏 心轮 9的转动, 使得转轮 93带动卡板 3运动, 使得卡板 3能够相对塔身 1和压板 8 移动。从而卡板 3能够脱离对销轴 2的定位位置, 使得转轮 93从锁紧位置移到松开位 置并对应卡板 3从对销轴 2的定位位置到达脱离对销轴 2的定位, 从而实现了不需拆 卸卡板 3即可更换销轴 2, 克服了现有技术更换销轴 2需拆卸卡板 3、容易损坏连接处 的问题, 进而达到了更换方便、 降低了施工强度且不会造成卡板 3丢失的效果。 如图 8至图 10所示的卡板位置示意图所示,其中, 图 8为卡板 3处于最右端极限 位置时的位置示意图, 此时偏心轮 9的旋转角度为 0°; 图 9为偏心轮 9的旋转角度为 90°时的卡板 3的位置示意图; 图 10为卡板处于最右端极限位置时的位置示意图, 此 时偏心轮 9旋转角度为 180°。 在上述图中, r为转轴 91的半径, R为转轮 93的半径, L1为当卡板 3处于最右端极限位置时销轴 2的圆心到卡板 3的最左端的距离, L2为 当卡板 3处于最左端极限位置时销轴 2的圆心到卡板 3的最左端的距离。 设卡板总行 程为 L, 由图可知:
L=L 1 -L2=(2R-r)-r=2(R-r)。 由以上图示还可得出, 在本实施例中, 尺寸 L1大于销轴 2的半径, 以保证卡板 3 在最右端极限位置时能够完全从销轴 2的凹槽内部退出, 从而不会影响销轴 2的安装 和拆卸; L2大于销轴 2的凹槽的半径尺寸, 以保证在最左端极限位置时卡板 3能够嵌 入到销轴 2的凹槽内, 从而能够实现卡板对销轴 2的限位功能。 优选地, L2与销轴 2 的凹槽的半径尺寸相等。 第二调整孔 33为纵向腰形槽, 其横向尺寸为 h 其纵向尺寸为 h2, 转轮 93的转 动半径为 R, 转轴 91的转动半径为 r, 其中: O h i^R^O^hz-i^ 如图 8至图 10可知, 该转轮 93的转动半径 (R) 大于或等于第二调整孔 33的水 平方向的口径 (0.51^ ) 与转轴半径 (R)之差并且小于第二调整孔 33垂直方向的口径 ( 0.5h2)与转轴半径(r)之差, 以保证转轮 93能够在转动中通过对第二调整孔 33的 内壁施力, 从而能够推动卡板 3沿水平方向移动。 优选地, 如图 5所示, 卡板 3具有与销轴 2的卡槽 21相配合定位的结构。 销轴 2 具有环形卡槽 21, 卡板 3例如为直板, 卡板 3的端部厚度小于环形卡槽 21的宽度, 因而, 卡板 3的端部可以插进环形卡槽 21中, 对销轴 2定位。 这种定位方式, 结构简 单、 便于加工。 优选地, 如图 5所示, 偏心轮 9具有手柄 95, 这样, 便于旋转的操作。 优选地,如图 3至图 5所示,固定布料机塔身与销轴连接的结构还包括定位销 10, 连接偏心轮 9与压板 8, 用于固定偏心轮 9, 使偏心轮 9到达极限位置(包括锁紧位置 和松开位置) 后被锁紧, 从而保持塔身 1与销轴 2连接的稳定性。 如图 3所示, 偏心 轮 9的转轴 91上设有销孔 97, 压板 8的轴套 83上设有销孔 85, 定位销 10穿设在销 孔 97与销孔 85中。 优选地, 定位销 10为弹簧销。 这样, 便于拆卸。 优选地, 如图 3所示, 第一调整孔 31为长条形, 这样, 便于铣床加工。 如图 3所示, 本发明还提供了一种布料机, 包括塔身 1、设置在塔身 1中的销轴 2 以及前面的塔身间连接件的固定结构。 由于具有上述塔身间连接件的固定结构, 这种 布料机不需频繁拆装卡板 3, 降低了施工强度且不会造成卡板 3丢失。 如图 8至图 10所示, 固定布料机塔身 1与销轴 2连接的结构安装好后,顺时针旋 转偏心轮 9将卡板 3退位到最右端极限位置 (如图 8所示)。 打入连接塔身用销轴 2。 销轴 2到位后, 逆时针旋转偏心轮 9, 在外力驱动下, 卡板 3向左滑行(如图 9所示)。 最后卡板 3左端面顶入销轴 2环形卡槽 21内, 卡板 3到达最左端极限位置 (如图 10 所示)。 此时将弹簧销插入压板 8与偏心轮 9各自的销孔, 卡板 3止动。 需拆卸销轴 2 时, 上述动作相反即可。 从以上的描述中, 可以看出, 本发明上述的实施例实现了如下技术效果: 本发明不需频繁拆装卡板, 降低了施工强度且不会造成设备部件丢失, 而且结构 简单, 便于加工、 安装。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
