技术领域Technical Field
本实用新型涉及塑料件抗压检测技术领域,具体为一种塑料件用抗压检测装置。The utility model relates to the technical field of plastic part compression detection, in particular to a plastic part compression detection device.
背景技术Background technique
塑料件抗压检测是保证批量化生产塑料件质量保障手段之一,主要方式是利用压力设备对塑料件施压压力,测量塑料件变形时的极限值,塑料件抗压检测装置是一种用于测试塑料件抗压性能的设备;它通常由一个压力传感器、一个压力加载系统和一个数据采集系统组成;在测试过程中,塑料件被放置在加载系统下方,加载系统通过施加压力来对塑料件进行压缩,直至塑料件失效,进而检测出塑料件的抗压能力。The compression test of plastic parts is one of the means to ensure the quality of plastic parts in mass production. The main method is to use pressure equipment to apply pressure to plastic parts and measure the limit value of plastic parts deformation. The compression test device for plastic parts is a device used to test the compression performance of plastic parts; it usually consists of a pressure sensor, a pressure loading system and a data acquisition system; during the test, the plastic parts are placed under the loading system, and the loading system compresses the plastic parts by applying pressure until the plastic parts fail, thereby detecting the compression resistance of the plastic parts.
现有的塑料件抗压检测装置通常是将塑料件放置在平台上,压头从上方对塑料件进行施压,进而检测塑料件的抗压能力,但是对于底部没有小平面的异形塑料件而言,难以按照预定方向放置在平台上,使得难以指定异形塑料件的受压方向,进而使得难以准确测出异形塑料件在指定方向上的受压能力,因此,我们提出一种塑料件用抗压检测装置来解决上述中存在的问题。Existing plastic part compression testing devices usually place the plastic part on a platform, and the pressure head applies pressure to the plastic part from above to test the compression resistance of the plastic part. However, for special-shaped plastic parts without a small flat surface on the bottom, it is difficult to place them on the platform in a predetermined direction, making it difficult to specify the compression direction of the special-shaped plastic parts, and further making it difficult to accurately measure the compression resistance of the special-shaped plastic parts in the specified direction. Therefore, we propose a plastic part compression testing device to solve the above problems.

支撑板6上表面固定安装有定位盘7,定位盘7为圆形,定位盘7设置在压盘4的正下方,定位盘7与压盘4同轴设置,定位盘7外侧套设有连接环8,连接环8转动连接在定位盘7外侧,连接环8内部设置有用于塑料件定位的限位板,限位板为栅状结构,限位板包括第一连接柱13、栅条杆14和第二连接柱15,第一连接柱13为圆柱形,转动连接在连接环8内侧,第一连接柱13竖直设置,第一连接柱13一侧固定设置有栅条杆14,栅条杆14均匀设置在第一连接柱13一侧,栅条杆14为四棱柱,且栅条杆14长度方向垂直于第一连接柱13轴线方向,栅条杆14远离第一连接柱13的一端固定设置有第二连接柱15,第二连接柱15与第一连接柱13相互平行,栅条杆14之间的间隙大于栅条杆14宽度的两倍,限位板环形分布在连接环8内侧,数量为三个,三个栅状的限位板相互交织,在三个限位板交织后形成一个等边三角形的区域,定位盘7的上表面开设有滑槽12,滑槽12环形分布在定位盘7上表面,且滑槽12在定位盘7上表面中心向外呈辐射状分布,滑槽12的数量为三个,第二连接柱15的下端滑动连接在滑槽12内部,由第一连接柱13、栅条杆14和第二连接柱15构成的限位板一端转动链接在连接环8内侧,另一端下部被定位盘7上表面开设的滑槽12所限制,当逆时针转动套设在定位盘7外侧的连接环8时,连接环8带动转动连接在其内侧的限位板运动,由于限位板一端的第二连接柱15滑动连接在滑槽12内部,使得相互交织的栅状限位之间的相互运动,进而使得三个限位板为成的三角形区域减小,反之,顺时针转动连接环8时,三个限位板为成的三角形区域增大。A positioning plate 7 is fixedly installed on the upper surface of the support plate 6. The positioning plate 7 is circular and is arranged directly below the pressure plate 4. The positioning plate 7 is coaxially arranged with the pressure plate 4. A connecting ring 8 is sleeved on the outer side of the positioning plate 7. The connecting ring 8 is rotatably connected to the outer side of the positioning plate 7. A limiting plate for positioning the plastic part is arranged inside the connecting ring 8. The limiting plate is a grid-like structure. The limiting plate includes a first connecting column 13, a grid bar rod 14 and a second connecting column 15. The first connecting column 13 is cylindrical and rotatably connected to the inner side of the connecting ring 8. The first connecting column 13 is cylindrical and rotatably connected to the inner side of the connecting ring 8. The column 13 is vertically arranged, and a bar bar 14 is fixedly arranged on one side of the first connecting column 13. The bar bar 14 is evenly arranged on one side of the first connecting column 13. The bar bar 14 is a quadrangular column, and the length direction of the bar bar 14 is perpendicular to the axis direction of the first connecting column 13. A second connecting column 15 is fixedly arranged on one end of the bar bar 14 away from the first connecting column 13. The second connecting column 15 is parallel to the first connecting column 13. The gap between the bar bars 14 is greater than twice the width of the bar bar 14. The limit plates are annularly distributed in the connecting ring 8. The number of the three chute plates is three, and the three grating-shaped limiting plates are interwoven with each other. After the three limiting plates are interwoven, an equilateral triangle area is formed. A slide groove 12 is provided on the upper surface of the positioning plate 7. The slide groove 12 is annularly distributed on the upper surface of the positioning plate 7, and the slide groove 12 is radially distributed outward from the center of the upper surface of the positioning plate 7. The number of the slide groove 12 is three, and the lower end of the second connecting column 15 is slidably connected to the inside of the slide groove 12. One end of the limiting plate composed of the first connecting column 13, the grating bar 14 and the second connecting column 15 is rotatably connected to the connecting column 13. On the inner side of the connecting ring 8, the lower part of the other end is restricted by the slide groove 12 provided on the upper surface of the positioning plate 7. When the connecting ring 8 sleeved on the outer side of the positioning plate 7 is rotated counterclockwise, the connecting ring 8 drives the limit plate connected to the inner side thereof to move. Since the second connecting column 15 at one end of the limit plate is slidably connected inside the slide groove 12, the interwoven grid-like limit plates move relative to each other, thereby reducing the triangular area formed by the three limit plates. Conversely, when the connecting ring 8 is rotated clockwise, the triangular area formed by the three limit plates increases.
连接环8外侧套设有蜗轮9,蜗轮9固定安装在连接环8外侧,支撑板6上表面转动连接有蜗杆10,且蜗杆10啮合在蜗轮9外侧,支撑板6上表面固定安装有伺服电机11,且蜗杆10固定安装在蜗轮9的输出端,伺服电机11带动固定安装在其输出端的蜗杆10转动时,蜗杆10通过与其相啮合的蜗轮9带动转动连接在定位盘7外侧的连接环8转动,对于底部没有小平面的异形塑料件而言,难以按照预定方向放置在平台上,使得难以指定异形塑料件的受压方向,在使用该塑料件抗压检测装置对塑料件进行抗压能力检测时,将塑料件放置在由三个限位板围成的三角形区域内部,蜗杆10通过与其相啮合的蜗轮9带动转动连接在定位盘7外侧的连接环8转动,进而调节由限位板围成的三角形区域的大小,使得限位板的三个面抵接在塑料件外侧,定位盘7上表面支撑住塑料件,此时即可通过定位盘7上方的压盘4对塑料件进行施压,从而测出塑料件在指定方向上的抗压能力,该塑料件抗压检测装置通过转动连接环8改变交织的限位板围成的空间的大小,进而对底部没有小平面的异形塑料件进行稳定的定位,使得塑料件能够按照预定方向放置在支撑板6上,进而能够准确测出异形塑料件在指定方向上的受压能力,值得注意的是,使用该塑料件抗压检测装置对塑料件进行抗压检测时,塑料件的高度需要高于限位板的高度,当电动推杆3带动压盘4下降到最低处上,压盘4下表面仍高于限位板的上部边缘。A worm wheel 9 is sleeved on the outside of the connecting ring 8, and the worm wheel 9 is fixedly installed on the outside of the connecting ring 8. A worm 10 is rotatably connected to the upper surface of the support plate 6, and the worm 10 is meshed with the outside of the worm wheel 9. A servo motor 11 is fixedly installed on the upper surface of the support plate 6, and the worm 10 is fixedly installed at the output end of the worm wheel 9. When the servo motor 11 drives the worm 10 fixedly installed on its output end to rotate, the worm 10 drives the connecting ring 8 connected to the outside of the positioning plate 7 to rotate through the worm wheel 9 meshed with it. For special-shaped plastic parts without small flat surfaces on the bottom, it is difficult to place them on the platform in a predetermined direction, making it difficult to specify the compressive direction of the special-shaped plastic parts. When using the plastic part compression testing device to test the compression resistance of the plastic parts, the plastic parts are placed inside the triangular area surrounded by three limit plates, and the worm 10 drives the connecting ring connected to the outside of the positioning plate 7 to rotate through the worm wheel 9 meshed with it. 8 rotates, and then adjusts the size of the triangular area surrounded by the limit plates, so that the three surfaces of the limit plates abut against the outside of the plastic part, and the upper surface of the positioning plate 7 supports the plastic part. At this time, the plastic part can be pressed by the pressure plate 4 above the positioning plate 7, so as to measure the pressure resistance of the plastic part in a specified direction. The plastic part pressure resistance detection device changes the size of the space surrounded by the interwoven limit plates by rotating the connecting ring 8, and then stably positions the special-shaped plastic part without a small plane at the bottom, so that the plastic part can be placed on the support plate 6 in a predetermined direction, and then the pressure resistance of the special-shaped plastic part in the specified direction can be accurately measured. It is worth noting that when using the plastic part pressure resistance detection device to perform pressure resistance detection on the plastic part, the height of the plastic part needs to be higher than the height of the limit plate. When the electric push rod 3 drives the pressure plate 4 to drop to the lowest point, the lower surface of the pressure plate 4 is still higher than the upper edge of the limit plate.
