Plastic pipe creep ratio testing machine, two light rods are installed on the left and right sides of the bottom plate, two light rods are installed with a ball screw, the upper beam is fixed on the top of the light rod, the ball screw drives the middle beam to move up and down, the specimen is placed in the fixture under the middle beam, the force sensor is installed between the middle beam and the fixture, and the main machine is composed of shell, servo motor, synchronous belt and synchronous wheel. The output shaft of the servo motor is connected with the left and right synchronous wheels through the synchronous belt, and the left and right ball screw are connected with the corresponding synchronous wheels respectively. The utility model uses a servo motor as power source, and is driven to two ball screw by synchronous wheel and belt as reducer. The ball screw drives the middle beam to move up and down along the bare rod, and the force sensor is fixed on the top of the middle beam to move with it. The displacement of the middle beam is controlled by the servo motor. The utility model can be widely used in creep ratio test of pipes, and has the advantages of reasonable design, convenient operation and stable and reliable accuracy.

塑料管材蠕变比率试验机
本技术涉及一种土工织物表面摩擦特性检测仪器,具体涉及一种塑料管材蠕变比率试验机。
技术介绍
在分子水平上,塑料材料是由大量长链分子组成的,当施加载荷时,微观上链分子将立刻受到挤压,宏观上产生产品的形变。当产品受到持续的载荷时,链分子将在力的作用下相互移动,产生蠕变,即连续增加的变形。因此对塑料管材进行蠕变比率试验成为一项反应棺材质量的必不可少的工作,目前的塑料管材蠕变比率试验机结构复杂,试件安装固定麻烦,测试过程费时费力,测试精度不稳定。
技术实现思路
本技术针对现有技术存在的不足,提供了一种塑料管材蠕变比率试验机。本技术解决其技术问题所采用的技术方案是:一种塑料管材蠕变比率试验机,包括主机、底板、光杆、上梁、中梁、夹具和控制柜,主机安装在底板上,两根光杆分别安装在底板的左右两侧,两根光杆上分别设置一个滚珠丝杠,上梁固定在光杆顶部,滚珠丝杠带动中梁在光杆上上下移动,试件置于中梁下方的夹具中,中梁和夹具之间安装力值传感器,主机由机壳、伺服电机、同步带和同步轮组成,伺服电机输出轴通过同步带分别与左右两个同步轮传动连接,左右两个滚珠丝杠分别与相应的同步轮 ...
