下面结合附图对本发明的具体实施例进行详细说明。
实施例 1
如图 1 - 4所示， 本发明所提出的打核机 A, 包括一机头 83, 上模座 (图 中未示）， 下模座 4， 机架 84及脚踏板 85。 当需要在布料上安装按钮时， 将 需要结合的按钮部件分别放置在上、下模座上，然后踩下脚踏板 85,带动上、 下模座相对运动， 从而将按扭安装在布料上。 本实施例的打钮机 A具有一打 钮机緩冲装置， 其包括一緩冲筒 1及与之固定连接的一緩冲盖 5, 所述緩冲 筒 1内 有一下模托 2,—用来安装下模的下模座 4放置于所述下模托 2上， 所述下模托 2下方套设有一弹簧 3， 其中， 所述緩冲筒 1内还设置有一打钮 力度调节装置， 该打钮力度调节装置设置在上述弹簧 3下方， 借助所述打钮 力度调节装置可改变上述弹簧 3的长度， 以改变打钮机的打钮力度。
具体来说， 所述緩冲筒 1于中心沿轴向具有一贯通的阶梯孔 11 , 且靠近 緩沖盖 5—侧较大通孔 111的直径大于远离緩冲盖 5的较小通孔 112的直径， 该緩沖筒 1于靠近緩冲盖 5—侧内设有至少一长槽 12，并于该侧的圆环壁上 设置有多个螺纹孔 13。
上述下模托 2设于上述緩沖筒 1的较大通孔 111内并顶抵于其较小通孔 112的端壁上， 所述下模托 2具有一结合端 21和固定端 22， 该结合端 21供 上述弹簧 3穿套定位，该固定端 22顶抵于緩沖筒 1，该下模托 2于固定端 22 的一侧沿轴向设置有一凹孔 23以承托上述下模座 4。
所述打钮力度调节装置包括一调节件 6和与之配合的一活动托 7, 所述 活动托 7设置在上述弹簧 3下方，该活动托 7具有一滑动端 71和限位端 72, 于滑动端 71周向上设有至少一个凸柱 711， 在本实施例中， 对称设有两个凸 柱 711， 该凸柱 711可卡在所述长槽 12内并沿该长槽 12位移； 该活动托 7 于滑动端 71—侧沿轴向凹设有一弹簧座 73以供上述弹簧 3容设定位。 所述 P艮位端 72沿径向贯穿有一通孔 722， 一滚针轴 74设置于该通孔 722内， 且 该滚针轴 74的长度大于活动托 Ί的通孔 722长度， 以使滚针轴 74的两端显 露出该通孔 722外。
上述打钮力度调节装置包括一调节件 6, 其与上述活动托 7的限位端 72 相连。 所述调节件 6具有一连接端 61和一操作端 62， 该调节件 6于连接端 61一侧沿中心轴向内凹设有一连接孔 63， 以供上述活动托 7的限位端 72容 置， 该调节件 6于连接端 61的端面上设置有至少两道凹槽 64， 以供上述滚 针轴 74嵌置， 各个凹槽 64的深浅度不一， 其间最好为光滑过度（如图 5、 6 所示）。 其中， 还可在滚针轴 74的两端分别套设滚针轴承 741 , 来减少其与 调节件 6的摩擦。
上述緩冲盖 5沿其中心轴亦设置有一贯通的阶梯孔 51， 且靠近緩冲筒 1 一侧较大通孔 511的直径大于远离緩冲筒 1较小通孔 512的直径， 在该緩沖 盖 5的圆环壁上设置有与緩冲筒 1上的螺纹孔 13对应的通孔 52,该緩冲盖 5 通过螺丝 53等合适的固定件固定连接于緩冲筒 1上。上述调节件 6的操作端 62穿出上述阶梯孔 51而显露于外，而其连接端 61容设于该緩沖盖 5的较大 通孔 511 内并挡止于该较小通孔 512的端壁上。 另外， 还可在上述调节件 6 与緩沖盖 5之间设置平面轴承 54, 以减少调节件 6的摩擦。
所述下模托 2设置于该緩沖筒 1的阶梯孔 11内， 且其固定端 22挡止于 较小通孔 112的端壁上； 上述弹簧 3套在上述下模托 2的结合端 21 , 上述活 动托 7由其凸柱 711插入上述緩冲筒 1的长槽 12内，上述弹簧 3—端顶抵于 下模托 2的固定端 22，另一端借助弹簧座 73而顶抵定位于上述活动托 7;上 述滚针轴 74插入活动托 7的通孔 722内， 并于其两端安装滚针轴承 741， 上 述调节件 6借助连接孔 63套在活动托 7的限位端 72上，并使滚针轴 74对应 设入调节件 6的凹槽 64内。 连接端 61挡止于緩沖盖 5的较小通孔 512的端 壁上，并使其通孔 52与緩沖筒 1的螺纹孔 13对应设置。螺丝 53穿过上述緩 沖盖 5的通孔 52并螺入緩沖筒 1的螺纹孔 13，以将上述緩冲盖 5与緩冲筒 1 固定连接起来；上述下模座 2从上述緩冲筒 1的阶梯孔 11穿入并放置于上述 下模托 2的凹孔 23内。 通过螺丝 14将本发明的緩沖装置安装于打钮机上， 如图 4所示。
当布料较厚或层数较多则需要增加打钮力度， 此时手动或通过工具（例 如扳手 )转动上述调节件 6的操作端 62使弹簧 3压缩。 由于上述活动托 7 的凸柱 711嵌置于緩冲筒 1的长槽 312内， 即活动托 7不能转动， 上述调节 件 6相对活动托 7转动，以使活动托 7上的滚针轴 74在弹簧 3的偏压下从调 节件上的深度较深的凹槽 64转动到深度较浅的凹槽 64中， 从而推动活动托 7向外运动压缩弹簧 3 , 进而增加打钮力度。
而当布料稍薄或层数变薄较少时， 由于打钮力度已经设定为较大， 则由 于緩冲装置的存在则不需要再次调机以减轻打钮力度。 而当布料厚度变薄较 多时， 为了避免打鈕力度过大将布料打穿， 则需要降低打鈕力度， 此时需要 转动调节件 6，使滚针轴 74在弹簧 3的偏压下从深度较浅的凹槽转动到深度 较深的凹槽中， 使弹簧 3长度增加， 从而减小了打钮力度。
本发明的緩冲装置应用时， 可根据目前打钮力度的需要， 在緩冲装置上 设置两种力度： 1500牛顿和 3800牛顿。 1500牛顿的力度与上述调节件 6其 中一较深凹槽 64相对应， 此时适合打轻型产品； 3800牛顿的力度与上述调 节件 6其中一较浅凹槽 64相对应， 此时适合打重型产品。 其中， 可将各个凹 槽 64的位置对应体现在调节件 6的操作端 62相对緩冲盖 5旋转的角度上， 例如为 50度。 即緩冲装置起点位置的力度为 1500牛顿， 向左旋转调节件 62 约 50度位置的力度为 3800牛顿，若再需转换成 1500牛顿，则向右旋转调节 件 62约 50度位置即可。 同样本领域技术人员可以明白 , 亦可将上述角度位 置通过标记的方式设置在緩沖盖 5上。 力度的设置经过精确仪器的测量，.在 转换力度时既准确又快速， 相应的力度作用在相应的产品上， 能确保打出合 格的产品。
综上所述， 本发明的緩冲装置既能确保产品的安全使用性， 又能减轻操 作者的劳动强度， 调机一步到位; 而本发明操作简单， 一般的操作人员经过 简单培训就会操作， 不必使用资深技工操作， 从而提高了其生产效率， 同时 节省了成本。 实施例 2
本实施例的结构与上述实施例基本相同， 其区别仅在于本实施例是电动 操作， 其结构相同之处不再详细描述。 如图 7-10所示， 在本实施例中， 所述 打钮力度调节装置还包括一与调节件 6相连的皮带轮 65， 所述皮带轮 65与 调节件 6的操作端 62以键 67配合连接，例如在操作端 61上具有键槽，在皮 带轮 65的中心孔中亦具有键槽，键 67插置其中从而将皮带轮 65与调节件 6 固定连接起来；所述皮带轮 65通过一皮带 66与一步进电机 81相连。所述调 节件 6的连接端 61与上述活动托 7以螺纹连接，该调节件 6可转动地设置于 所述活动托 7内， 当步进电机 81带动皮带轮 65转动一个角度， 调节件 6的 连接端 61相对活动托 7转动同样的角度， 从而使得活动托 7会在调节件 6 的转动下而轴向移动，进而改变了弹簧 3的长度，其结果是改变了打钮力度。
其中， 可在上述緩冲盖与调节件 6之间设置平面轴承 54， 以减少其间的 摩擦， 在本实施例中， 緩冲盖 5内具有一凸台 55， 在凸台 55上下两侧均设 置平面轴承 54, 同时在调节件 6的操作端 62上且于键槽上方设有一螺紋段 68, 螺母 10等合适的固定件螺设其中， 即， 位于凸台 55上侧的平面轴承 54 固定于调节件 6的挡块 69与凸台 55之间， 位于凸台 55下侧的平面轴承 54 固定于凸台 55与螺母 10之间， 螺母 10的作用是支承平面轴承 54， 并防止 平面 松动。
本实施例还可以包括一电脑控制器 82， 使用时预先在该电脑控制器 82 上设置相应的力度，例如，设置数字键 1代表 1500牛顿，数字键 2代表 3800 牛顿， 数字键 3代表 4500牛顿 （数字键 4 - 9待设定）， 使用时， 接通电源， 先将电脑控制器 82归零，然后根据产品结合时所需要的力度去选择其中一个 数字键,按下相应的数字键，上述皮带轮 65和调节件 6就能完成力度的转换。 应当理解， 上述电脑控制器及其工作原理并非本发明所要保护的细节， 本领域技术人员根据本发明所提出的打钮机緩沖装置可以自由地选择现有的 控制装置或控制程序。
以上所述仅为本发明的具体实施例而已， 不能以此限定本发明实施的范 围； 即大凡依本发明权利要求书所作的任何变化与修改， 皆属本发明专利保 护的范围。
