使用本实用新型时，由于包括支架1、第一驱动机构、导轨3、第一卡盘4、第二驱动机构和第二卡盘6，其中，第一驱动机构和导轨3均安装在支架1一侧，而第一卡盘4滑动安装在导轨3上，第一驱动机构一端与第一卡盘4活动连接在一起，接通外界电源，使得第一驱动机构被驱动的时候，第一驱动机构一端可以驱动第一卡盘4沿着导轨3的轴向进行往复滑动；另外，第二驱动机构和第二卡盘6均安装在支架1另一侧，而且，第二驱动机构一端与第二卡盘6传动连接，接通外界电源，使得第二驱动机构被驱动的时候，第二驱动机构一端可以驱动第二卡盘6进行转动，而且第一卡盘4、外界扭簧和第二卡盘6依次电连接并构成回路。在使用该扭簧疲劳试验装置对扭簧进行试验的时候，将外界芯棒装夹在第一卡盘4和第二卡盘6上(在第一卡盘4和第二卡盘6上均安装有扭转棒)，然后将外界扭簧套入该芯棒中，通过伺服系统(即第一驱动机构和第二驱动机构)调节第一卡盘4和第二卡盘6之间的位置，可以安装不同尺寸、长度和型号的扭簧，通用性非常高，例如，将一卡盘右移至接近第二卡盘6，然后将扭簧的两臂轻放入第一卡盘4和第二卡盘6之间，使得第一卡盘4通过扭转棒装夹着扭簧一端，而第二卡盘6通过扭转棒装夹着扭簧另一端，接通外界电源，试验参数并开启试验，第一电机被驱动，使得第一电机输出端带动丝杆22进行转动，使得转动中的丝杆22通过螺母滑块23带动第一卡盘4沿着导轨3的轴向进行往复滑动，同时，第二电机51被驱动时，第二电机51输出端依次通过第三齿轮52和第四齿轮53带动第二卡盘6进行转动，可以对安装在第一卡盘4和第二卡盘6之间的扭簧进行试验，而且，由于第一卡盘4、外界扭簧和第二卡盘6依次电连接并构成回路，当扭簧没有断裂时，试验到达预定循环次数后自动停机，等待人员查看结果，当扭簧中途断裂时，检测回路断开，伺服系统检测到回路中断后系统停机，待人员查看试验结果，可以准确计算所进行的试验次数，试验效率高，非常方便。能解决现有技术中的扭簧疲劳试验机一般只适用于尺寸和形状相似的几款弹簧，即通用性低，而且难以准确计算所进行的试验次数，导致试验效率低的问题。When using the utility model, due to comprising support 1, first drive mechanism, guide rail 3, first chuck 4, second drive mechanism and second chuck 6, wherein, first drive mechanism and guide rail 3 are all installed on support 1 One side, and the first chuck 4 is slidably installed on the guide rail 3, one end of the first drive mechanism is movably connected with the first chuck 4, and the external power supply is connected, so that when the first drive mechanism is driven, the first drive One end of the mechanism can drive the first chuck 4 to reciprocate and slide along the axial direction of the guide rail 3; in addition, the second driving mechanism and the second chuck 6 are installed on the other side of the bracket 1, and one end of the second driving mechanism is connected to the first The two chucks 6 are connected by transmission, and the external power supply is connected, so that when the second driving mechanism is driven, one end of the second driving mechanism can drive the second chuck 6 to rotate, and the first chuck 4, the external torsion spring and the second The chucks 6 are electrically connected in turn to form a circuit. When using this torsion spring fatigue testing device to test the torsion spring, the external mandrel is clamped on the first chuck 4 and the second chuck 6 (both on the first chuck 4 and the second chuck 6 Torsion bar is installed), then the external torsion spring is inserted into the mandrel, and the position between the first chuck 4 and the second chuck 6 is adjusted by the servo system (ie, the first drive mechanism and the second drive mechanism), Torsion springs of different sizes, lengths and models can be installed, and the versatility is very high. For example, move one chuck to the right to approach the second chuck 6, and then gently place the arms of the torsion spring into the first chuck 4 and the second chuck Between the two chucks 6, the first chuck 4 clamps one end of the torsion spring through the torsion bar, and the second chuck 6 clamps the other end of the torsion spring through the torsion bar, connect the external power supply, test the parameters and start the test , the first motor is driven, so that the output end of the first motor drives the screw mandrel 22 to rotate, so that the rotating screw mandrel 22 drives the first chuck 4 to reciprocate and slide along the axial direction of the guide rail 3 through the nut slider 23, and at the same time , when the second motor 51 is driven, the output end of the second motor 51 drives the second chuck 6 to rotate through the third gear 52 and the fourth gear 53 in turn, which can be installed on the first chuck 4 and the second chuck 6 The torsion spring between them is tested, and since the first chuck 4, the external torsion spring and the second chuck 6 are electrically connected in turn to form a circuit, when the torsion spring is not broken, the test will automatically stop after the predetermined number of cycles, and wait Personnel check the results. When the torsion spring breaks halfway, the detection circuit is disconnected. After the servo system detects that the circuit is interrupted, the system shuts down. After the personnel checks the test results, the number of tests can be accurately calculated. The test efficiency is high and it is very convenient. It can solve the problem that the torsion spring fatigue testing machine in the prior art is generally only suitable for several types of springs with similar sizes and shapes, that is, the universality is low, and it is difficult to accurately calculate the number of tests performed, resulting in low test efficiency.
