For a unified description, the following takes the spherical product 200 to be tested as an example to describe the automatic rotary drop test machine 100.
请参阅图1至图3,自动旋转跌落试验机100包括机座1、旋转机构2、移送机构3以及拾取机构4,其中,机座1具有间隔设置的旋转工位11及跌落工位12;旋转机构2设于机座1,用以将旋转工位11处的待测产品200旋转至所需角度;移送机构3设于机座1,用以将待测产品200自旋转工位11移送至跌落工位12;拾取机构4可升降地安装于机座1,用以自跌落工位12拾取待测产品200并提升至所需高度后释放。1 to 3, the automatic rotary drop test machine 100 includes a base 1, a rotating mechanism 2, a transfer mechanism 3, and a pickup mechanism 4. The base 1 has a rotating station 11 and a drop station 12 arranged at intervals; The rotating mechanism 2 is set on the machine base 1 to rotate the product 200 to be tested at the rotating station 11 to a desired angle; the transfer mechanism 3 is set on the machine base 1 to transfer the product 200 to be tested from the rotating station 11 To the drop station 12; the pick-up mechanism 4 is mounted on the machine base 1 so as to be lifted and lowered to pick up the product 200 to be tested from the drop station 12 and release it after being lifted to a desired height.
本发明提供的技术方案中,旋转机构2将待测产品200旋转至所需角度后,移送机构3将待测产品200移送至跌落工位12,供拾取机构4拾取并提升至所需高度后释放,试验过程由旋转机构2、移送机构3及拾取机构4自动完成,无需依赖人工操作,具有跌落点准确且效率高的优点,有助于优化试验效果。In the technical solution provided by the present invention, after the rotating mechanism 2 rotates the product 200 to be tested to a required angle, the transfer mechanism 3 transfers the product 200 to be tested to the drop station 12 for the picking mechanism 4 to pick up and lift it to the required height. Release, the test process is automatically completed by the rotating mechanism 2, the transfer mechanism 3, and the picking mechanism 4, without relying on manual operation, and has the advantages of accurate drop point and high efficiency, which helps to optimize the test effect.
可以理解的是,所述机座1用以连接并支撑所述旋转机构2、所述移送机构3以及所述拾取机构4,可以具体表现为箱体状或者架体状等;机座1可以为整体式结构,也可以由多个分体构件组合构成,每一分体构件的形状及尺寸等具体表现形式与对应位置处的旋转机构2、移送机构3以及拾取机构4相适配;多个分体构件可以一体成型设置,也可以通过例如焊接、螺接或者卡扣扣合等方式连接成一体。It is understandable that the base 1 is used to connect and support the rotating mechanism 2, the transfer mechanism 3, and the pick-up mechanism 4, and may be embodied in a box shape or a rack shape, etc.; the base 1 may It is a monolithic structure, which can also be composed of a combination of multiple split components. The specific expressions such as the shape and size of each split component are adapted to the rotating mechanism 2, the transfer mechanism 3, and the pickup mechanism 4 at the corresponding position; more The separate components may be integrally formed and arranged, or they may be connected into one body by means such as welding, screw connection, or snap-fitting.
旋转工位11与跌落工位12间隔设置,且旋转机构2对应旋转工位11处设置,拾取机构4对应跌落工位12处设置,使得待测产品200的角度调节操作与跌落试验操作互不干涉,有助于自动旋转跌落试验机100的角度调节操作与跌落试验操作的同时进行,从而提高自动旋转跌落试验机100的试验效率。移送机构3将待测产品200自旋转工位11移送至跌落工位12,实现同一待测产品200的角度调节操作与跌落试验操作的准确衔接,有助于消除人工作业时容易产生操作误差的问题。The rotating station 11 and the drop station 12 are arranged at intervals, and the rotating mechanism 2 is arranged at the rotating station 11, and the picking mechanism 4 is arranged at the drop station 12, so that the angle adjustment operation of the product under test 200 and the drop test operation are mutually exclusive The interference helps the angle adjustment operation of the automatic rotary drop test machine 100 and the drop test operation to be performed at the same time, thereby improving the test efficiency of the automatic rotary drop test machine 100. The transfer mechanism 3 transfers the product under test 200 from the rotating station 11 to the drop station 12 to realize the accurate connection between the angle adjustment operation and the drop test operation of the same product under test 200, which helps to eliminate the easy operation errors during manual operations. The problem.
进一步地,请参阅图4及图5,在一实施例中,旋转机构2包括两个夹持部21、第一驱动器22及第二驱动器23,其中,两个夹持部21分设于旋转工 位11的相对两侧,且沿相互靠近和相互远离的夹持方向可移动设置,夹持部21沿夹持方向的轴线可旋转;第一驱动器22用于驱动两个夹持部21沿夹持方向移动,以夹持待测产品200;第二驱动器23用以驱动夹持部21沿夹持方向的轴线旋转,以通过夹持部21带动待测产品200旋转至所需角度。第一驱动器22可驱动连接两个夹持部21中的一个,然后控制该夹持部21朝另一夹持部21靠近,以实现对处于两个夹持部21中间的待测产品200的夹持固定或者解除固定;或者,第一驱动器22可以对应两个夹持部21设置有两个,分别驱动两个夹持部21相互靠近或者相互远离,以实现对处于两个夹持部21中间的待测产品200的夹持固定或者解除固定。其中,第一驱动器22可以是例如与丝杠等传动组件配合使用的电机,也可以直接由例如无杆气缸单独构成。同理地,第二驱动器23可驱动连接两个夹持部21中的至少一个,例如,旋转机构2包括两个轴承座,两个夹持部21分别通过一转轴转动安装在两个轴承座上;第二驱动器23为伺服电机,驱动连接其中一夹持部21,当两个夹持部21夹持固定待测产品200后,待测产品200实现了两个夹持部21的连接,使得在第二驱动器23驱动与之连接的夹持部21转动时,另一夹持部21及待测产品200实现同步转动。Further, referring to FIGS. 4 and 5, in one embodiment, the rotating mechanism 2 includes two clamping parts 21, a first driver 22, and a second driver 23, wherein the two clamping parts 21 are separately provided in the rotating work The two opposite sides of the position 11 are movably arranged along the clamping direction close to and away from each other, and the clamping part 21 is rotatable along the axis of the clamping direction; the first driver 22 is used to drive the two clamping parts 21 along the clamping direction. The second driver 23 is used to drive the clamping portion 21 to rotate along the axis of the clamping direction, so as to drive the product 200 to be tested to rotate to a desired angle through the clamping portion 21. The first driver 22 can drive and connect one of the two clamping parts 21, and then control the clamping part 21 to approach the other clamping part 21, so as to realize the detection of the product 200 to be tested in the middle of the two clamping parts 21 Clamping fixed or unfixed; or, the first driver 22 may be provided with two corresponding to the two clamping parts 21, respectively driving the two clamping parts 21 to approach or move away from each other, so as to realize the alignment between the two clamping parts 21 The product 200 to be tested in the middle is clamped and fixed or unfixed. Among them, the first driver 22 may be a motor used in conjunction with a transmission component such as a lead screw, or may be directly constituted by, for example, a rodless cylinder alone. Similarly, the second driver 23 can drive to connect at least one of the two clamping parts 21. For example, the rotating mechanism 2 includes two bearing seats, and the two clamping parts 21 are respectively rotatably mounted on the two bearing seats via a rotating shaft. On; the second driver 23 is a servo motor, drivingly connected to one of the clamping parts 21, when the two clamping parts 21 clamp and fix the product under test 200, the product under test 200 realizes the connection of the two clamping parts 21, As a result, when the second driver 23 drives the clamping part 21 connected to it to rotate, the other clamping part 21 and the product to be tested 200 realize synchronous rotation.
需要注意的是,旋转机构2中的两个夹持部21活动安装在机座1的同一安装平台上,此时,以球形的待测产品200为例,且以所述安装平台为参考平面,可选设置两个夹持部21的旋转轴线的高度相当,且两个夹持部21的旋转轴线的高度与球形待测产品200的球心高度相当,使得当两个夹持部21夹持固定待测产品200并旋转时,大致可模拟出待测产品200的自转,有助于提高角度调节的准确度。进一步地,还可以在旋转工位11的周向围设围框,以限制球形的待测产品200在所述安装平台上滚动。It should be noted that the two clamping parts 21 in the rotating mechanism 2 are movably installed on the same installation platform of the machine base 1. At this time, the spherical product under test 200 is taken as an example, and the installation platform is taken as the reference plane. Optionally, the heights of the rotation axes of the two clamping parts 21 are equivalent, and the height of the rotation axes of the two clamping parts 21 is equivalent to the height of the sphere center of the spherical product 200 to be tested, so that when the two clamping parts 21 clamp When the product under test 200 is held fixed and rotated, the rotation of the product under test 200 can be roughly simulated, which helps to improve the accuracy of angle adjustment. Further, a frame may be provided around the rotation station 11 to restrict the spherical product 200 to be tested from rolling on the installation platform.
接着,在本实施例中,旋转机构2设有至少两个,且两个旋转机构2的两个夹持方向呈交叉设置;以旋转机构2设有两个为例,两个旋转机构2的两个夹持方向可选大致呈垂直设置,两个旋转机构2的四个夹持部21沿旋转工位11的周向间隔设置,有助于增加待测产品200的角度调节范围,从而增加自动旋转跌落试验机100的实用性。Next, in this embodiment, at least two rotating mechanisms 2 are provided, and the two clamping directions of the two rotating mechanisms 2 are arranged crosswise; taking the two rotating mechanisms 2 as an example, the two rotating mechanisms 2 The two clamping directions can be set approximately vertically, and the four clamping parts 21 of the two rotating mechanisms 2 are arranged at intervals along the circumference of the rotating station 11, which helps increase the angular adjustment range of the product 200 to be tested, thereby increasing The practicality of the automatic rotating drop test machine 100.
