Description

一种大冲击载荷加载装置A large impact load loading device

技术领域Technical field

本发明属于零部件性能测试设备技术领域,尤其涉及一种大冲击载荷加载装置。The invention belongs to the technical field of component performance testing equipment, and in particular relates to a large impact load loading device.

背景技术Background technique

在很短的时间内(作用时间小于受力机构的基波自由振动周期的一半)以很大的速度作用在构件上的载荷称为冲击载荷。冲击荷载是评定材料脆性与韧性程度的重要参数,其应力与变形量的计算相当复杂,计算时一般按照机械能守恒定律进行。The load that acts on a component at a very high speed in a short period of time (the action time is less than half of the fundamental free vibration period of the force-bearing mechanism) is called an impact load. Impact load is an important parameter for evaluating the brittleness and toughness of materials. The calculation of stress and deformation is quite complicated. The calculation is generally carried out according to the law of conservation of mechanical energy.

现有的冲击测试方法主要有摆锤式、落锤式和拉伸冲击式,而在上述三种方法中,摆锤式和落锤式是较为常用的冲击测试方法。但是在实际测试时,无论是摆锤式还是冲击式都只能从单一的方向对材料进行冲击测试,其中落锤式主要是从顶部对材料进行撞击,而摆锤式则主要是从侧面对材料进行撞击,因此当需要对同一材料进行顶部以及侧面的冲击测试时,需要使用不同的测试仪器,或者在完成材料的某一面冲击测试后,重新调整材料并固定,因此较为麻烦,此外,由于现有的测试仪器都有测量范围,因此对于一些抗冲击性能较大的材料而言,不易测量出该类材料的抗冲击性能的最大值范围。The existing impact testing methods mainly include pendulum type, drop weight type and tensile impact type. Among the above three methods, pendulum type and drop weight type are the more commonly used impact testing methods. However, in actual testing, both the pendulum type and the impact type can only impact the material from a single direction. The drop hammer type mainly impacts the material from the top, while the pendulum type mainly impacts the material from the side. The material is impacted, so when the same material needs to be impact tested on the top and side, it is necessary to use different testing instruments, or after completing the impact test on a certain side of the material, the material is readjusted and fixed, so it is more troublesome. In addition, because Existing test instruments all have measurement ranges, so for some materials with high impact resistance, it is not easy to measure the maximum range of the impact resistance of such materials.

因此,发明一种大冲击载荷加载装置来解决上述问题很有必要。Therefore, it is necessary to invent a large impact load loading device to solve the above problems.

The area inside the ring 702, and as the toothed ring 702 continues to rotate, when the notch of the toothed ring 702 rotates to the position of the fork lever 5, the electric gear lever 704 rotates out of the storage groove, thereby connecting the fork bar 5 and the toothed ring 702 Locked together, as the ring gear 702 continues to rotate, the stopper 703 on the ring gear 702 can push the pendulum rod 5, causing it to drive the pendulum ball 6 to gradually move upward along the inner edge of the ring gear 702. When the pendulum rod 5 moves When it reaches the notch position at the top of the conical cylinder 2, the second motor 710 stops rotating. At this time, the swing rod 5 is located at the highest point of the larger end of the conical cylinder 2 opening;

在对材料进行抗冲击测试时,若需要对材料的顶部进行抗冲击测试,先启动第一电机707,使其带动弧形杆705向靠近挡块703的一侧偏转,从而使弧形杆705不再对摆杆5进行限制,当弧形杆705完全与摆杆5的底部错开时,使电动挡杆704迅速收回到收纳槽中,此时由于摆杆5不再受到电动挡杆704的限制,摆球6能够在重力的作用下带动摆杆5以固定球4为圆心向下偏转并撞击在设备夹紧台16顶部的待测试材料上,此时材料受到的冲击力能够根据动量定理公式F=mv求得,其中F为材料所受到的冲击力,m为摆球6的质量,v为摆球6撞击材料时的速度,其中摆球6的质量能够通过称量直接获得,而摆球6撞击材料时的速度能够通过激光测速传感器8测量获得,从而通过两个数据的乘积即可获得材料顶部的抗冲击测试数据;When performing an impact resistance test on the material, if it is necessary to perform an impact resistance test on the top of the material, first start the first motor 707 to drive the arc rod 705 to deflect to the side close to the stop 703, thereby causing the arc rod 705 to deflect. The swing rod 5 is no longer restricted. When the arc-shaped rod 705 is completely staggered from the bottom of the swing rod 5, the electric blocking rod 704 is quickly retracted into the storage groove. At this time, the swing rod 5 is no longer affected by the electric blocking rod 704. Limit, the pendulum ball 6 can drive the pendulum rod 5 to deflect downward with the fixed ball 4 as the center of the circle under the action of gravity and hit the material to be tested on the top of the equipment clamping table 16. At this time, the impact force on the material can be determined according to the momentum theorem. It is obtained by the formula F=mv, where F is the impact force on the material, m is the mass of the pendulum ball 6, and v is the speed when the pendulum ball 6 hits the material. The mass of the pendulum ball 6 can be directly obtained by weighing, and The speed of the pendulum ball 6 when it hits the material can be measured by the laser speed sensor 8, so that the impact resistance test data on the top of the material can be obtained by multiplying the two data;

若需要对材料的侧面进行抗冲击测试时,能够先使弧形杆705保持初始状态,接着使电动挡杆704迅速收回到收纳槽中,此时,由于摆杆5不再受到电动挡杆704的限制,摆杆5能够在弧形杆705的导向作用下沿着齿环702的内壁加速向下摆动,并且在摆球6向下偏转的过程中,虽然弧形杆705的长度小于齿环702内侧周长的一半,但是当摆球6向下偏转至二分之一齿环702高度位置时,由于摆球6具有一定的速度,因此摆球6会在离心力的作用下继续沿着齿环702的内侧进行圆周运动,当摆球6移动至锥形筒2内侧边缘最底部时,摆球6会以水平方向的速度冲击在待检测材料的侧面,此时再次根据动量定理公式,即可在无需调整待检测材料的前提下实现对材料顶部以及侧面的抗冲击测试,提高了测试效率。If it is necessary to conduct an impact resistance test on the side of the material, the arc-shaped rod 705 can be maintained in the initial state first, and then the electric blocking rod 704 can be quickly retracted into the storage groove. At this time, since the swing rod 5 is no longer affected by the electric blocking rod 704 limit, the pendulum rod 5 can accelerate and swing downward along the inner wall of the ring gear 702 under the guidance of the arc rod 705, and during the downward deflection of the pendulum ball 6, although the length of the arc rod 705 is smaller than the ring ring 702 inner circumference, but when the pendulum ball 6 deflects downward to half the height of the toothed ring 702, since the pendulum ball 6 has a certain speed, the pendulum ball 6 will continue to move along the gear ring under the action of centrifugal force. The inner side of the ring 702 performs circular motion. When the pendulum ball 6 moves to the bottom of the inner edge of the conical cylinder 2, the pendulum ball 6 will impact the side of the material to be detected at a horizontal speed. At this time, according to the momentum theorem formula again, that is Impact resistance testing on the top and sides of the material can be achieved without adjusting the material to be tested, improving testing efficiency.

如图1和图2所示,压动组件9包括两个连接杆91,两个连接杆91呈前后分布,且两个连接杆91的中部之间垂直贯穿插接有同一个驱动轴92,且驱动轴92的一端连接有第三电机93,第一电机707、第二电机710以及第三电机93均为步进电机,其能够在断电状态下自动锁定,从而能够避免齿环702、电动挡杆704以及压杆96分别在第一电机707、第二电机710以及第三电机93突然断电的情况下,失去对齿环702、电动挡杆704以及压杆96的控制作用,保证本发明的使用安全,驱动轴92靠近两端的位置均转动套接有安装板94,两个安装板94的底部固定连接有同一个支撑台95,支撑台95固定连接在底座1顶部,两个连接杆91的两端之间均垂直连接有压杆96,且压杆96能够与摆杆5远离摆球6的一端接触,两个安装板94与锥形筒2之间设有加速组件,压杆96上转动套接有压辊15,压辊15位于压杆96的中间位置,且压辊15的直径由两端向中间逐渐减小;As shown in Figures 1 and 2, the pressing assembly 9 includes two connecting rods 91. The two connecting rods 91 are distributed front and back, and the same driving shaft 92 is vertically inserted between the middle portions of the two connecting rods 91. And one end of the drive shaft 92 is connected to a third motor 93. The first motor 707, the second motor 710 and the third motor 93 are all stepper motors, which can automatically lock in a power-off state, thereby preventing the ring gear 702, When the first motor 707, the second motor 710 and the third motor 93 suddenly lose power respectively, the electric gear lever 704 and the pressure lever 96 lose their control over the ring gear 702, the electric gear lever 704 and the pressure lever 96, ensuring that The present invention is safe to use. The driving shaft 92 is rotatably connected to a mounting plate 94 near both ends. The bottoms of the two mounting plates 94 are fixedly connected to the same support platform 95. The support platform 95 is fixedly connected to the top of the base 1. Two A pressure rod 96 is vertically connected between both ends of the connecting rod 91, and the pressure rod 96 can contact the end of the swing rod 5 away from the swing ball 6. An acceleration assembly is provided between the two mounting plates 94 and the tapered cylinder 2. A pressure roller 15 is rotatably connected to the pressure rod 96. The pressure roller 15 is located in the middle of the pressure rod 96, and the diameter of the pressure roller 15 gradually decreases from both ends toward the middle;

加速组件包括升降台10,升降台10固定连接在支撑台95的顶部,升降台10的顶部固定连接有两个伸缩杆11,且伸缩杆11的顶端向靠近驱动轴92的方向倾斜,两个伸缩杆11关于摆杆5呈前后对称分布,且伸缩杆11上套接有弹簧12,两个伸缩杆11的顶端之间转动连接有支撑杆13,且支撑杆13能够与摆杆5接触;The acceleration assembly includes a lifting platform 10. The lifting platform 10 is fixedly connected to the top of the support platform 95. The top of the lifting platform 10 is fixedly connected with two telescopic rods 11, and the top of the telescopic rod 11 is tilted in the direction close to the drive shaft 92. The two The telescopic rod 11 is symmetrically distributed front and back with respect to the swing rod 5, and a spring 12 is connected to the telescopic rod 11. A support rod 13 is rotatably connected between the tops of the two telescopic rods 11, and the support rod 13 can contact the swing rod 5;

在对材料进行最大冲击性能的测试时,随着第三电机93的启动,第三电机93能够通过驱动轴92带动两个压杆96围绕着驱动轴92转动,当其中一个压杆96上的压辊15自上而下压动摆杆5时,摆杆5远离摆球6的一端能够逐渐向下偏转并与支撑杆13靠近,当摆杆5与支撑杆13接触时,随着压杆96继续压动摆杆5,两个伸缩杆11能够在支撑杆13的压动下压缩两个弹簧12,随着压杆96的继续运动,当压辊15与摆杆5分离时,随着压辊15对摆杆5限制力的移除,两个弹簧12能够自动复位,从而通过两个伸缩杆11推动支撑杆13和摆杆5远离摆球6的一端一起向上偏转,从而使得摆杆5获得一个初始加速度,进而能够使得摆球6能够在该加速的作用下快速冲击在材料的表面,进而根动量定理公式,计算得出此时材料所承受的冲击力,随后观察材料是否发生明显的形变或者破损来判定材料是否达到最大冲击荷载,如果没有,则能够升高升降台10,并重复上述操作,但是与上述测试过程中不同的是,由于升降台10高度提升了,支撑杆13的高度也随着提升,因此在压杆96压动摆杆5偏转相同角度的情况下,弹簧12的压缩程度进一步提升,从而导致在压杆96与摆杆5分离的瞬间,弹簧12对支撑杆13的反作用力更大,从而能够使摆球6获得更大的初速度,进而实现摆球6对材料冲击力度的逐渐增加,如此往复即可最终实现对材料最大抗冲击性能范围的测试。When testing the maximum impact performance of the material, with the start of the third motor 93, the third motor 93 can drive the two pressure rods 96 to rotate around the drive shaft 92 through the drive shaft 92. When one of the pressure rods 96 is When the pressure roller 15 presses the fork 5 from top to bottom, the end of the fork 5 away from the pendulum ball 6 can gradually deflect downward and approach the support rod 13. When the fork 5 contacts the support rod 13, as the pressure rod 96 continues to press the fork bar 5, and the two telescopic rods 11 can compress the two springs 12 under the pressure of the support rod 13. As the pressure bar 96 continues to move, when the pressure roller 15 separates from the fork bar 5, as When the pressure roller 15 removes the restricting force of the pendulum bar 5, the two springs 12 can automatically reset, thereby pushing the support rod 13 and the end of the pendulum rod 5 away from the pendulum ball 6 to deflect upward together through the two telescopic rods 11, thereby causing the pendulum rod to deflect upward. 5 obtains an initial acceleration, which enables the pendulum ball 6 to quickly impact the surface of the material under the action of the acceleration. Then, based on the momentum theorem formula, the impact force endured by the material at this time is calculated, and then it is observed whether the material has any obvious deformation or damage to determine whether the material has reached the maximum impact load. If not, the lifting platform 10 can be raised and the above operation can be repeated. However, what is different from the above test process is that since the height of the lifting platform 10 is raised, the support rod 13 The height also increases, so when the pressure rod 96 presses the swing bar 5 to deflect at the same angle, the compression degree of the spring 12 further increases, resulting in the moment when the pressure rod 96 and the swing bar 5 separate, the spring 12 supports the The reaction force of the rod 13 is greater, so that the pendulum ball 6 can obtain a greater initial velocity, thereby gradually increasing the impact force of the pendulum ball 6 on the material. By repeating this process, the test of the maximum impact resistance range of the material can be finally achieved.

当需要对材料进行最大抗冲击性能测试时,随着摆杆5穿过锥形筒2上的缺口并继续向上偏转,两个限位板14能够对摆杆5进行限制,避免在摆球6下落的过程中,摆杆5因偏斜与锥形筒2上的缺口内壁发生磕碰,从而能够保证摆球6沿竖直方向向下冲击在材料表面。When the material needs to be tested for maximum impact resistance, as the pendulum rod 5 passes through the gap in the conical cylinder 2 and continues to deflect upward, the two limiting plates 14 can limit the pendulum rod 5 to avoid the pendulum ball 6 During the falling process, the pendulum rod 5 collides with the inner wall of the notch on the conical cylinder 2 due to deflection, thereby ensuring that the pendulum ball 6 impacts the material surface downward in the vertical direction.

以上实施例仅用以说明本发明的技术方案,而非对其限制。The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
