一种快速散热的切割机 技术领域
本发明涉及切割机领域，具体涉及的是一种快速散热的切割机。
背景技术
切割机主要用于在机械加工过程中，对板材进行切割分离。现有的切割机主要在主轴箱内设有转动连接的主轴，主轴上安装切割锯片，并且通过驱动装置驱动主轴转动，从而带动切割锯片进行切割。在切割过程中，由于主轴高速转动，会使得主轴和轴承的温度过高，从而使主轴和轴承膨胀，影响切割精度。
为了解决上述主轴和轴承温度过高的问题，现有的切割机大多在主轴箱的侧壁上开通冷却液流槽，并向冷却液流槽内输送流动的冷却液，通过冷却液吸热的方式来对主轴箱进行散热冷却处理。但现有的冷却方式中，由于冷却液只能在主轴箱内循环流动，无法与主轴以及轴承直接接触，导致吸热效果较差，无法对主轴和轴承进行快速降温。
有鉴于此，本申请人针对上述问题进行深入研究，遂有本案产生。

优选的，由于主轴贯穿主轴箱1设置，主轴的一端设有第一轴承31和第二轴承32，主轴的另一端设有第三轴承，因此第一冷却腔12和第二冷却腔13对应轴承的安装位置分布在主轴箱1的两端，储液腔11处于第一冷却腔12和第二冷却腔13之间。
更优选的，储液腔11的一端与第一冷却腔12连通且另一端与第二冷却腔13连通。采用此结构，使得第一冷却腔12和第二冷却腔13内的冷却液在吸热冷却后可以向主轴箱1的中部回流至储液腔11内。
优选的，储液腔11的侧壁设有与第一冷却腔12连通的第一连通口，以及与第二冷却腔13连通的第二连通口，冷却液通过第一连通口流入和流出第一冷却腔12，冷却液通过第二连通口流入和连出第二冷却腔13。

优选的，由于第一冷却腔12内设有第一轴承31和第二轴承32，因此第一冷却腔12内需要较多的冷却液，第一进液口121包括设在第一冷却腔12上表面的第一进液孔1211和第二进液孔1212，第一分流管道21包括第一分流支管211和第二分流支管212，第一进液孔1211和第一分流支管211连接，第二进液孔1212和第二分流支管212连接。采用此结构，第一进液孔1211和第二进液孔1212可同时流入冷却液，可加速冷却液流入第一冷却腔12的流速同时增加冷却液的流量，使得对两个轴承的冷却更加高效。
优选的，为了防止第一分流支管211和第二分流支管212在主轴箱1内窜动而相互打结，主轴箱1还设有连通于储液腔11和第一冷却腔12之间的过渡腔14，过渡腔14用于容置第一分流支管211和第二分流支管212。
更优选的，为了进一步固定第一分流支管211和第二分流支管212，过渡腔14的侧壁设有连通储液腔11的夹持孔141，夹持孔141固定第一分流支管211与第二分流支管212。

优选的，第二容置腔124对应第二进液孔1212设置，第二进液孔1212内的冷却液可流入第二容置腔124内对第二轴承32进行冷却。
更优选的，第二容置腔124设在第二进液孔1212的正下方，此结构使得第二进液孔1212内的冷却液能够更快进入第二容置腔124，并快速与第二轴承32接触吸热，提高了散热效率。
优选的，第一冷却腔12还包括将冷却液从第一进液口121导向第一容置腔123和第二容置腔124的导油套125。导油套125的两个端面与第一轴承31和第二轴承32的端面抵顶，对第一轴承31和第二轴承32之间起到一定限位效果。同时，当冷却液进入导油套125后，导油套125可将冷却液直接分流至第一轴承31的端面和第二轴承32的端面，从第一轴承31的内部和第二轴承32的内部进行冷却，从而加速冷却，使得冷却更加高效。
优选的，导油套125对应第一进液孔1211设置。使得第一进液孔1211内的冷却液能够人流入导油套125并在导油套125的作用下导向第一轴承31和第二轴承32，从而进行冷却散热。
更优选的，导油套125设在第一进液孔1211的正下方，加快冷却液流入导油套125的速度，从而加快冷却液导入第一轴承31和第二轴承32，进一步提高冷却效率。
优选的，导油套125包括套设在主轴4上并抵顶于第一轴承31和第二轴承32内圈之间的内限位套1251，以及套设在内限位套1251外并抵顶于第一轴承31和第二轴承32外圈之间的外限位套1252。采用上述结构后，导油套125在主轴4转动时，对第一轴承31和第二轴承32的端面进行抵顶，从而限制第一轴承31和第二轴承32沿主轴4的轴线方向窜动，使第一轴承31和第二轴承32安装更加牢固。
优选的，内限位套1251和外限位套1252之间具有导液间隙1253，外限位套形1252成有与间隙相连通的导液孔1255。采用上述结构后，第一进液孔1211内的冷却液通过导液孔1255进入导液间隙1253，并将冷却液从导液间隙1253导向第一轴承31与第二轴承32。
优选的，第一轴承31和第二轴承32的轴承游隙均与导液间隙1253连通，使得冷却液能够直接流入第一轴承31和第二轴承32内部并进行吸热冷却。
更优选的，第一轴承31和第二轴承32的轴承游隙位置均与导液间隙2553相对应，此结构可加快冷却液流入轴承游隙，从而加速轴承冷却。
优选的，由于导液孔1255孔径较小，冷却液流入导液间隙1253的速度较慢，为了防止第一冷却孔1211内的冷区液四处流动，外限位套1252的周面形成有与导液孔1255连通的环形储液槽1254，环形储液槽1254与第一进液孔1211连通。环形储液槽1254可将第一进液孔1211流出的冷却液暂时存储。
优选的，环形储液槽1254与第一进液孔1211相对应。
更优选的，环形储液槽1254设在第一进液孔的正下方，加快第一进液孔1211内的冷却液能够直接流入环形储液槽1254内。
优选的，第二冷却腔13设有安装第三轴承33的安装槽133。第三轴承33嵌入安装槽133内部，使得第三轴承33安装更加牢固。
