[0008] 进一步改进， 所述动颚的宽度为 L， 所述动颚的厚度为 H; 所述肘板槽距离所 述动颚宽度方向两端的距离为 D， 其中 0.05L^EK0.2L; 所述肘板槽的深度为 W， 其中 1/3HSWS2/3H。 肘板槽两端与动颚两端的距离 D在上述范围内， 本发明中的 动颚更可靠性， 使用寿命更长。 所述肘板槽的深度为 W， 所述肘板槽的深度在上 述范围内， 在保证本发明中的动颚具有良好结构强度、 延长动颚的使用寿命的 前提下， 肘板可更加深入的进入至肘板槽内与动颚连接， 使得本发明有效的节 约占用空间， 利于生产现场的布置。
[0009] 进一步改进， 所述肘板槽具有开口， 上下相对的第一侧面和第二侧面， 左右相 对的第三侧面和第四侧面， 以及与对着开口的底面； 所述第一侧面沿着指向所 述肘板槽外部的方向向上倾斜设置； 所述第二侧面沿着指向所述肘板槽外部的 方向向下倾斜设置。 本发明中肘板槽的横街面为不规则四边形， 所述肘板槽在 向着动颚外部的方向为敞口型。 方便本发明中动颚与肘板配合连接， 敞口结构 的肘板槽方便工具的伸入， 方便肘板的安装。
[0010] 进一步改进， 所述底面为平面， 所述肘板槽的第一侧面与底面之间的夹角为第 一夹角， 所述第一夹角为钝角； 所述肘板槽的第二侧面对底面之间的夹角为第 二夹角， 所述第二夹角为钝角。 本发明中肘板槽的第一侧面和第二侧面与底面 之间的第一夹角和第二夹角越大， 越能避免本发明中动颚受到肘板的巨大破碎 力时由于肘板槽槽两面角度变化过于陡 （角度越小， 两面之间的角度变化越尖 锐） 造成的应力集中， 利于延长本发明中动颚的使用寿命， 利于提高本发明的 可靠性。
[0011] 进一步改进， 所述第一夹角的角度较所述第二夹角的角度小。 即本发明中由于 肘板槽位于动颚的下部， 因此肘板安装的过程中需要一个相对较大的空间， 以 及在肘板安装的过程中， 肘板多是从肘板槽的下侧进入或者移出， 第二夹角的 角度设置大于第一夹角， 使得肘板槽的下部敞开角度更大， 利于肘板槽或者肘 板垫的拆装操作。 [0012] 进一步改进， 所述第一侧面的宽度为 W1， 所述第二侧面的宽度为 W2， 其中 W 1 < W2。 第二侧面的宽度较第一侧面的宽度窄， 使得本发明中动颚下端的厚度较 小且形状规则， 避免了动颚下部肘板槽的下部向外凸出， 因此肘板在安装过程 中动颚不会对肘板的移动和安装造成阻碍， 同时也利于减轻本发明的重量。
[0013] 进一步改进， 所述底面为曲面， 所述第一侧面和所述第二侧面分别与所述底面 的上下两端相切设置。 本发明中将肘板槽的第一侧面和第二侧面设置为与底面 相切， 进一步减小了肘板槽内主要受力面上各面之间角度的变化， 减少动颚在 肘板槽处因肘板处的作用力发生应力集中， 本发明具结构强度好， 具有较长的 使用寿命。
[0014] 进一步改进， 所述肘板槽内装有至少一片肘板垫， 所述肘板垫位于所述动颚和 所述肘板之间。 由于肘板与动颚之间的相互作用力大， 为了避免二者之间发生 严重的摩擦， 损害肘板与动颚接触位置的结构， 因此在肘板槽内安装有肘板垫 ， 保护肘板和动颚， 肘板槽发生摩擦后可以进行更换， 利于本发明的长期稳定 使用。
[0015] 进一步改进， 所述肘板槽的底面设有多个定位孔， 所述定位孔水平设置， 所述 肘板垫通过固定螺栓与所述定位孔配合将所述肘板垫锁紧在所述肘板槽内。 通 过上述设置， 配合肘板槽的结构， 方便肘板垫的拆装。 进一步优选， 肘板槽的 敞口结构， 肘板垫和肘板的拆装更加方便， 设备的安装维护也更加方便。

发明实施例
本发明的实施方式
[0028] 为了进一步解释本发明的技术方案， 下面通过具体实施例来对本发明进行详细 阐述。
[0029] 实施例一
[0030] 本实施例公开一种嵌入式动颚总成， 如图 1至图 3所示， 包括动颚 1和肘板 2， 所 述动颚 1为箱式结构， 所述动颚 1上部设有偏心轴通孔 11， 所述动颚 1下部设有肘 板槽 12, 所述肘板槽 12的中轴线与偏心轴通孔 11的中轴线平行； 沿着所述动颚 1 的厚度方向， 所述肘板槽 12嵌入所述动颚 1内； 沿着所述动颚 1宽度方向， 所述 肘板槽 12两端与所述动颚 1两端均留有一定的距离； 所述肘板 2伸入所述肘板槽 1 2中与所述动颚 1抵触连接。 本实施例中沿着所述动颚 1的厚度方向， 所述肘板槽 12嵌入所述动颚 1内； 沿着所述动颚 1宽度方向， 所述肘板槽 12两端与所述动颚 1 两端均留有一定的距离； 通过上述设置， 将原本置于动颚 1外部的肘板槽 12设置 于动颚 1内部， 肘板 2与动颚 1连接的一端可伸入动颚 1内部的肘板槽 12与动颚 1连 接， 节约了本实施例所占用的空间； 动颚 1下部的形状更加规则， 动颚 1的体积 减小和重量降低。 另一方面， 本实施例中动颚 1肘板槽 12两端与动颚 1两端留有 距离， 相对于现有技术中通槽结构的肘板槽 12， 本实施例中动颚 1上没有贯穿动 颚 1的缺口， 避免了颚式破碎机运行过程中本实施例受到肘板 2施加较大的破碎 力， 通槽结构的肘板槽 12发生应力集中引起动颚 1断裂， 提高本实施例的使用寿 命和可靠性。
[0031] 本实施例中优选所述本体 1的宽度为 L， 所述本体 1的厚度为 H; 所述肘板槽 12 距离所述本体 1宽度方向两端的距离为 D， 其中 D=0.05L; 所述肘板槽 12的深度为 W, 其中 W=1/3H; 相比于现有技术中动颚 16个月左右的使用寿命， 本实施例的 使用寿命可达 12个月至 24个月。 肘板槽 12两端与动颚 1两端的距离 D在上述范围 内， 本实施例中的动颚 1更可靠性， 使用寿命更长。 所述肘板槽 12的深度为 W， 所述肘板槽 12的深度在上述范围内， 在保证本实施例中的动颚 1结构强度好、 延 长动颚 1使用寿命的前提下， 肘板 2可更加深入的进入至肘板槽 12内与动颚 1连接 ， 本实施例有效节约占用空间， 利于生产现场布置。
[0032] 本实施例中所述肘板槽 12具有开口， 上下相对的第一侧面 121和第二侧面 122， 左右相对的第三侧面和第四侧面， 以及与对着开口的底面 123 ; 所述第一侧面 12 1沿着指向所述肘板槽 12外部的方向向上倾斜设置； 所述第二侧面 122沿着指向 所述肘板槽 12外部的方向向下倾斜设置。 本实施例中肘板槽 12的横街面为不规 则四边形， 所述肘板槽 12在向着动颚 1外部的方向为敞口型。 方便本实施例中动 颚丄与肘板 2配合连接， 敞口结构的肘板槽 12方便工具的伸入， 方便肘板 2的安装
[0033] 本实施例中所述底面 123为平面， 所述肘板槽 12的第一侧面 121与底面 123之间 的夹角为第一夹角， 所述第一夹角为钝角； 所述肘板槽 12的第二侧面 122对底面 123之间的夹角为第二夹角， 所述第二夹角为钝角。 本实施例中肘板槽 12的第一 侧面 121和第二侧面 122与底面 123之间的第一夹角和第二夹角越大， 越能避免应 力集中， 相比较于现有技术中动颚 1受到肘板 2的巨大破碎力时由于肘板槽 12两 面角度变化过于陡 （角度越小， 两面之间的角度变化越尖锐） 造成的应力集中 ， 本实施例中第一夹角和第二夹角均为钝角， 利于延长本实施例中动颚 1的使用 寿命， 利于提高本实施例的可靠性。 进一步优选， 第一侧面 121与底面 123之间 有一倒角过渡面， 第二侧面 122与底面 123之间也有一倒角过渡面， 通过过渡面 来弱化肘板槽 12第一侧面 121和第二侧面 122分别与底面 123之间的角度， 防止动 颚 1的肘板槽 12内应力集中。
[0034] 本实施例中所述第一夹角的角度较所述第二夹角的角度小。 本实施例中肘板槽 12位于动颚 1的下部， 肘板 2安装的过程中需要一个相对较大的空间， 以及在肘 板 2安装的过程中， 肘板 2多是从肘板槽 12的下侧进入或者移出， 第二夹角的角 度设置大于第一夹角， 使得肘板槽 12的下部敞开角度更大， 利于肘板槽 12或者 肘板垫 3的拆装操作。
[0035] 本实施例中所述第一侧面 121的宽度 （即肘板槽 12的第一侧面 121与底面 123的 相交线至第一侧面 121位于肘板槽 12开口一侧边缘线的垂直距离） 为 W1， 所述第 二侧面 122的宽度 （即肘板槽 12的第二侧面 122与底面 123的相交线至第二侧面 12 2位于肘板槽 12开口一侧边缘线的垂直距离） 为 W2， 其中 W1 < W2。 第二侧面 12 2的宽度较第一侧面 121的宽度窄， 使得本实施例中动颚 1下端的厚度较小且形状 规则， 避免了动颚 1下部肘板槽 12的下部向外凸出， 因此肘板 2在安装过程中动 颚 1不会对肘板 2的移动和安装造成阻碍， 同时也减轻本实施例的重量、 缩小本 实施例的体积。
[0036] 本实施例中所述肘板槽 12内装有至少一片肘板垫 3 , 所述肘板垫 3位于所述动颚 1和所述肘板 2之间。 肘板 2与动颚 1之间的相互作用力大， 为了避免二者之间发 生严重的摩擦， 损害肘板 2与动颚 1接触位置的结构， 因此在肘板槽 12内安装有 肘板垫 3 , 保护肘板 2和动颚 1， 肘板槽 12发生摩擦后可以进行更换， 利于本实施 例的长期稳定使用。
[0037] 本实施例中所述肘板槽 12的底面 123设有多个定位孔 124， 所述定位孔 124水平 设置， 所述肘板垫 3通过固定螺栓与所述定位孔 124配合将所述肘板垫 3锁紧在所 述肘板槽 12内。 通过上述设置， 配合肘板槽 12的结构， 方便肘板垫 3的拆装。 进 一步优选， 肘板槽 12为敞口结构， 肘板垫 3和肘板 2的拆装更加方便， 设备的安 装维护也更加方便。
[0038] 本实施例中的肘板槽 12由于位于动颚 1内部， 可以通过铣床获得肘板槽 12， 即 肘板槽 12与动颚 1为一体结构， 本实施例结构强度好； 同时在一定程度上降低了 动颚 1的重量， 用于推动本实施例自身重量的能量减少， 降低了能耗的使用， 用 于粉碎原料的能耗增加， 能耗的利用效率提高。
[0039] 实施例二
[0040] 如图 4和图 5所示， 本实施例与实施例一的主要区别在于， 本实施例中所述底面 123为曲面， 所述第一侧面 121和所述第二侧面 122分别与所述底面 123的上下两 端相切设置。 本实施例中将肘板槽 12的第一侧面 121和第二侧面 122设置为与底 面 123相切， 进一步减小了肘板槽 12内主要受力面上各面之间角度的变化， 减少 动颚 1在肘板槽 12处因肘板 2处的作用力发生应力集中， 本实施例结构强度好， 具有较长的使用寿命。
[0041] 另外， 本实施例中优选所述动颚 1的宽度为 L， 所述动颚 1的厚度为 H; 所述肘 板槽 12距离所述动颚 1宽度方向两端的距离 D=0.2L; 所述肘板槽 12的深度 W=2/3 H， 肘板 2可更加深入的进入至肘板槽 12内与本实施例连接， 兼顾本实施例能够 有效的节约安装空间。 相比于现有技术中动颚 16个月左右的使用寿命， 本实施 例中动颚 1的使用寿命可达 18个月至 24个月。
[0042] 实施例三
[0043] 本实施例公开一种具有嵌入式动颚的颚式破碎机， 如图 6， 图 7所示， 包括机架 4、 动颚 1、 肘板 2以及拉紧装置 5 , 动颚 1和肘板 2, 所述动颚 1为箱式结构， 所述 动颚 1上部设有偏心轴通孔 11， 所述动颚 1下部设有肘板槽 12, 所述肘板槽 12的 中轴线与偏心轴通孔 11的中轴线平行； 沿着所述动颚 1的厚度方向， 所述肘板槽 12嵌入所述动颚 1内； 沿着所述动颚 1宽度方向， 所述肘板槽 12两端与所述动颚 1 两端均留有一定的距离； 所述肘板 2伸入所述肘板槽 12中与所述动颚 1抵触连接 。 本实施例中沿着所述动颚 1的厚度方向， 所述肘板槽 12嵌入所述动颚 1内； 沿 着所述动颚 1宽度方向， 所述肘板槽 12两端与所述动颚 1两端均留有一定的距离 ; 通过上述设置， 将原本置于动颚 1外部的肘板槽 12设置于动颚 1内部， 肘板 2与 动颚 1连接的一端可伸入动颚 1内部的肘板槽 12与动颚 1连接， 节约了本实施例所 占用的空间； 动颚 1下部的形状更加规则， 动颚 1的体积和重量都得到了减小。 另一方面， 本实施例中动颚 1肘板槽 12两端与动颚 1两端留有距离， 相对于现有 技术中通槽结构的肘板槽 12, 本实施例中动颚 1上没有贯穿动颚 1的缺口， 避免 了颚式破碎机运行过程中本实施例受到肘板 2施加较大的破碎力， 通槽结构的肘 板槽 12发生应力集中引起动颚 1断裂， 提高本实施例的使用寿命和可靠性。
[0044] 本实施例中优选所述本体 1的宽度为 L， 所述本体 1的厚度为 H; 所述肘板槽 12 距离所述本体 1宽度方向两端的距离为 D， 其中 D=0.05L; 所述肘板槽 12的深度为 W, 其中 W=1/3H; 相比于现有技术中动颚 16个月左右的使用寿命， 本实施例的 使用寿命可达 12个月至 24个月。 肘板槽 12两端与动颚 1两端的距离 D在上述范围 内， 本实施例中的动颚 1更可靠性， 使用寿命更长。 所述肘板槽 12的深度为 W， 所述肘板槽 12的深度在上述范围内， 在保证本实施例中的动颚 1具有良好结构强 度、 延长动颚 1的使用寿命的前提下， 肘板 2可更加深入的进入至肘板槽 12内与 动颚 1连接， 使得本实施例有效的节约占用空间， 利于生产现场的布置。
[0045] 本实施例中所述肘板槽 12具有开口， 上下相对的第一侧面 121和第二侧面 122， 左右相对的第三侧面和第四侧面， 以及与对着开口的底面 123 ; 所述第一侧面 12 1沿着指向所述肘板槽 12外部的方向向上倾斜设置； 所述第二侧面 122沿着指向 所述肘板槽 12外部的方向向下倾斜设置。 本实施例中肘板槽 12的横街面为不规 则四边形， 所述肘板槽 12在向着动颚 1外部的方向为敞口型。 方便本实施例中动 颚丄与肘板 2配合连接， 敞口结构的肘板槽 12方便工具的伸入， 方便肘板 2的安装
[0046] 本实施例中所述底面 123为平面， 所述肘板槽 12的第一侧面 121与底面 123之间 的夹角为第一夹角， 所述第一夹角为钝角； 所述肘板槽 12的第二侧面 122对底面 123之间的夹角为第二夹角， 所述第二夹角为钝角。 本实施例中肘板槽 12的第一 侧面 121和第二侧面 122与底面 123之间的第一夹角和第二夹角越大， 越能避免应 力集中， 主要原因是本实施例中动颚 1受到肘板 2的巨大破碎力时由于肘板槽 12 槽两面角度变化过于陡 （角度越小， 两面之间的角度变化越尖锐） 造成的应力 集中， 而本实施例中第一夹角和第二夹角均为钝角， 利于延长本实施例中动颚 1 的使用寿命， 利于提高本实施例的可靠性。 进一步优选， 第一侧面 121与底面 12 3之间有一倒角过渡面， 第二侧面 122与底面 123之间也有一倒角过渡面， 通过过 渡面来弱化肘板槽 12第一侧面 121和第二侧面 122分别与底面 123之间的角度， 防 止动颚 1的肘板槽 12内应力集中。
[0047] 本实施例中所述第一夹角的角度较所述第二夹角的角度小。 本实施例中肘板槽 12位于动颚 1的下部， 肘板 2安装的过程中需要一个相对较大的空间， 以及在肘 板 2安装的过程中， 肘板 2多是从肘板槽 12的下侧进入或者移出， 第二夹角的角 度设置大于第一夹角， 使得肘板槽 12的下部敞开角度更大， 利于肘板槽 12或者 肘板垫 3的拆装操作。
[0048] 本实施例中所述第一侧面 121的宽度 （即肘板槽 12的第一侧面 121与底面 123的 相交线至第一侧面 121位于肘板槽 12开口一侧边缘线的垂直距离） 为 W1， 所述第 二侧面 122的宽度 （即肘板槽 12的第二侧面 122与底面 123的相交线至第二侧面 12 2位于肘板槽 12开口一侧边缘线的垂直距离） 为 W2， 其中 W1 < W2。 第二侧面 12 2的宽度较第一侧面 121的宽度窄， 使得本实施例中动颚 1下端的厚度较小且形状 规则， 避免了动颚 1下部肘板槽 12的下部向外凸出， 因此肘板 2在安装过程中动 颚 1不会对肘板 2的移动和安装造成阻碍， 同时也减轻本实施例的重量、 缩小本 实施例的体积。
[0049] 本实施例中所述肘板槽 12内装有至少一片肘板垫 3 , 所述肘板垫 3位于所述动颚 1和所述肘板 2之间。 肘板 2与动颚 1之间的相互作用力大， 为了避免二者之间发 生严重的摩擦， 损害肘板 2与动颚 1接触位置的结构， 因此在肘板槽 12内安装有 肘板垫 3 , 保护肘板 2和动颚 1， 肘板槽 12发生摩擦后可以进行更换， 利于本实施 例的长期稳定使用。
[0050] 本实施例中所述肘板槽 12的底面 123设有多个定位孔 124， 所述定位孔 124水平 设置， 所述肘板垫 3通过固定螺栓与所述定位孔 124配合将所述肘板垫 3锁紧在所 述肘板槽 12内。 通过上述设置， 配合肘板槽 12的结构， 方便肘板垫 3的拆装。 进 一步优选， 肘板槽 12为敞口结构， 肘板垫 3和肘板 2的拆装更加方便， 设备的安 装维护也更加方便。
[0051] 本实施例中的肘板槽 12由于位于动颚 1内部， 可以通过铣床获得肘板槽 12， 即 肘板槽 12与动颚 1为一体结构， 本实施例结构强度好； 同时在一定程度上降低了 动颚 1的重量， 用于推动本实施例自身重量的能量减少， 降低了能耗的使用， 用 于粉碎原料的能耗增加， 能耗的利用效率提高。 [0052] 上述实施例和图式并非限定本实施例的产品形态和式样， 任何所属技术领域的 普通技术人员对其所做的适当变化或修饰， 皆应视为不脱离本实施例的专利范 畴。
