Description

一种摆锤冲击试验机 技术领域
本发明涉及冲击试验机领域,具体涉及一种摆锤冲击试验机。

冲击试验机(英文名称:impact testing machine)是指对试样施加冲击试验力,进行冲击试验的材料试验机。冲击试验机分为手动摆锤式冲击试验机、半自动冲击试验机、数显冲击试验机、微机控制冲击试验机、落锤冲击试验机以及非金属冲击试验机等。可以通过更换摆锤和试样底座,可实现简支梁和悬臂梁两种形式的试验。
摆锤式冲击试验机是冲击试验机的一种,是用于测定金属材料在动负荷下抵抗冲击的性能,从而判断材料在动负荷作用下的质量状况的检测仪。

一种摆锤冲击试验机,包括底座1;所述底座1的一侧设有高架2;所述高架2的上方设有摆锤滑轴3;所述摆锤滑轴3上滑移安装有摆锤滑板4;所述摆锤滑板4的外端设有气缸架5;所述气缸架5的上端设有气缸6;所述气缸6的下端设有垂直滑板7;所述垂直滑板7的下端设有转轴10;所述转轴10上设有摆锤12。
所述垂直滑板7的下端还设有转向电机8;所述转向电机8上设有转轴齿轮11;所述转轴10上设有转向齿轮9;所述转轴齿轮11和转向齿轮9相啮合。
所述转向电机8的两端均设有转轴齿轮11;所述转轴10的两端均设有转向齿轮9;所述转向电机8两端的转轴齿轮11和转轴10两端的转向齿轮9相对应。
所述摆锤滑板4的下方设有摆锤滑块13;所述高架2上设有横移电机;所述横移电机上设有摆锤丝轴14;所述摆锤丝轴14和摆锤滑块13螺纹相接。
所述垂直滑板7上设有垂直滑板导轨;所述摆锤滑板4上设有垂直滑板卡槽;所述垂直滑板导轨和垂直滑板卡槽滑动卡嵌连接。
所述底座1上设有测试滑轴16;所述测试滑轴16上滑移安装有测试架15;所述测试架15上设有测试架滑块;所述底座1上设有测试电机18;所述测试电机18上设有测试丝轴17;所述测试丝轴17与测试架滑块螺纹相接。
所述测试架15上挡板19;所述挡板19和测试架15之间设有加强筋20。
所述测试架15上设有夹持架。
其工作原理为:
将测试材料放置于测试架15上,并通过夹持架对测试材料进行夹紧固定,然后通过测试丝轴17调节测试架15的前后位置。摆锤丝轴14则调节水平冲击的位置,以保证摆锤12能精准的对测试材料进行冲击实验。气缸6则调节纵向方向的冲击位置。
在进行实验时,转向电机8通电驱动转向齿轮9旋转,从而带动转轴齿轮11旋转,使得转轴10上的摆锤12发生倾角变化,当到达指定位置后,转向电机8的转向齿轮9失锁,使得摆锤12通过自身重力开始自由落体,从而进行冲击实验。
在实验中,可以对转向电机8的转向齿轮9进行反向瞬时驱动,起到助力作用,从而改变冲击力度的大小,具体通过改变转向齿轮9的转速即可。
对于本领域技术人员而言,显然本发明不限于上述示范性实施例的细节,而且在不背离本发明的精神或基本特征的情况下,能够以其他的具体形式实现本发明。因此,无论从哪一点来看,均应将实施例看作是示范性的,而且是非限制性的,本发明的范围由所附权利要求而不是上述说明限定,因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
