However, such measurement methods are mostly semi-automatic: the inspector needs to hold the optical measuring instrument to measure the circular axis, and record the measurement data one by one, and the detection efficiency is very low.

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
图1所示为本发明一实施例中检测装置100的示意图。如图1中所示,检测装置100包括基部110、光学测量部120、顶尖部130和PC-PLC控制中心(未图示)。其中,光学测量部120和顶尖部130均设置在基部110上并可相对基部110运动。FIG. 1 is a schematic diagram of a detecting apparatus 100 in accordance with an embodiment of the present invention. As shown in FIG. 1, the detecting device 100 includes a base 110, an optical measuring portion 120, a tip portion 130, and a PC-PLC control center (not shown). The optical measuring portion 120 and the tip portion 130 are both disposed on the base portion 110 and movable relative to the base portion 110.
具体地,基部110可用于安装光学测量部120和顶尖部130。基部110包括基板112和设于基板112上的第一导轨或基板导轨113。In particular, the base 110 can be used to mount the optical measurement portion 120 and the tip portion 130. The base 110 includes a substrate 112 and a first rail or substrate rail 113 disposed on the substrate 112.
基板112具有横向(图示为第一方向D1)和纵向(图示为第二方向D2)。在图1所示的实施例中,基板112呈矩形,第一方向D1为基板112的长度方向,第二方向D2为基板112的宽度方向。两条基板导轨113相互平行且间隔的设于基板112上。在图1所示的实施例中,两条基板导轨113分别沿着第一方向D1延伸,并在第二方向D2上相间设置。The substrate 112 has a lateral direction (illustrated as a first direction D1) and a longitudinal direction (illustrated as a second direction D2). In the embodiment shown in FIG. 1, the substrate 112 has a rectangular shape, the first direction D1 is the longitudinal direction of the substrate 112, and the second direction D2 is the width direction of the substrate 112. The two substrate guides 113 are disposed on the substrate 112 in parallel and spaced apart from each other. In the embodiment shown in FIG. 1, the two substrate guides 113 extend along the first direction D1 and are disposed in the second direction D2.
光学测量部120包括第二导轨或光学测量仪导轨122和设于光学测量仪导轨122上的光学测量仪123。The optical measuring portion 120 includes a second rail or optical gauge rail 122 and an optical gauge 123 disposed on the optical gauge rail 122.
两个光学测量仪导轨122相互平行且间隔地设置在基板导轨113上,并可相对基板导轨113运动。在图1所示的实施例中,两个光学测量仪导轨122分别沿着第二方向D2延伸,并在第一方向D1上间隔设置;换言之,光学测量仪导轨122垂直于基板导轨113。每一光学测量仪导轨122的两端安装在基板导轨113上,而且每一光学测量仪导轨122可沿着第一方向D1相对于基板导轨113运动。The two optical gauge rails 122 are disposed parallel to each other and spaced apart from each other on the substrate rail 113 and are movable relative to the substrate rail 113. In the embodiment shown in FIG. 1, the two optical gauge rails 122 extend along the second direction D2, respectively, and are spaced apart in the first direction D1; in other words, the optical gauge rails 122 are perpendicular to the substrate rails 113. Both ends of each optical gauge rail 122 are mounted on the substrate rail 113, and each optical gauge rail 122 is movable relative to the substrate rail 113 along the first direction D1.
光学测量仪123可滑动地安装在光学测量仪导轨122上。光学测量仪123的数量可根据实际使用需求进行调整,例如,可以为1个或多个。当光学测量仪123的数量为1个时,光学测量仪导轨122的数量可相应地改为一个。在图1所示的实施例中,光学测量仪导轨122的数量位多个并分别设置在光学测量仪导轨122上。光学测量仪123可沿着第二方向D2相对于光学测量仪导轨122滑动。The optical gauge 123 is slidably mounted on the optical gauge rail 122. The number of optical meters 123 can be adjusted according to actual use requirements, for example, one or more. When the number of optical gauges 123 is one, the number of optical gauge rails 122 can be changed to one accordingly. In the embodiment shown in FIG. 1, the number of optical gauge rails 122 is a plurality of and disposed on the optical gauge rails 122, respectively. The optical gauge 123 is slidable relative to the optical gauge rail 122 along the second direction D2.
由于光学测量仪导轨122垂直于基板导轨113并可沿着第一方向D1相对于基板导轨113滑动,以及光学测量仪123可沿着第二方向D2相对于光学测量仪导轨122滑动,因此,通过调节光学测量仪导轨122与基板导轨113之间的相对运动以及光学测量仪123与光学测量仪导轨122之间的相对运动,可将光学测量仪123调到合适的测量位置。Since the optical gauge rail 122 is perpendicular to the substrate rail 113 and is slidable relative to the substrate rail 113 along the first direction D1, and the optical gauge 123 is slidable relative to the optical gauge rail 122 along the second direction D2, By adjusting the relative motion between the optical gauge rail 122 and the substrate rail 113 and the relative motion between the optical gauge 123 and the optical gauge rail 122, the optical gauge 123 can be adjusted to a suitable measurement position.
顶尖部130包括第三导轨或顶尖导轨132、设于顶尖导轨132的两端的顶尖结构如第一顶尖结构133和第二顶尖结构135,以及V型支撑座136。The tip portion 130 includes a third rail or a tip rail 132, a tip structure such as a first tip structure 133 and a second tip structure 135, and a V-shaped support seat 136 provided at both ends of the tip rail 132.

如图1-3所示,当待检测圆轴200放置到V型支撑座136上时,待检测圆轴200位于第一顶尖结构133与第二顶尖结构135之间;此时,第一顶尖结构133与第二顶尖结构135中的气缸1335的气缸伸缩杆1336伸展或紧缩,与固定块13324上的凸出块13328相互作用,推动基座13323及上方的顶尖1338沿顶尖导轨132往基部110中间靠拢,使顶尖1338恰与待检测圆轴200的两端顶接即将待检测圆轴200夹紧。当顶尖1338与待检测圆轴200顶接后,在顶尖1338一侧的步进电机1339通过皮带带动顶尖1338转动,光学测量仪123对待检测圆轴200相关数据进行测量,并将数据反馈给PC-PLC控制中心。As shown in FIG. 1-3, when the to-be-detected round shaft 200 is placed on the V-shaped support base 136, the to-be-detected round shaft 200 is located between the first tip structure 133 and the second tip structure 135; at this time, the first tip The structure 133 and the cylinder telescoping rod 1336 of the cylinder 1335 in the second tip structure 135 extend or contract, interacting with the projections 13328 on the fixed block 13324, pushing the base 13323 and the upper tip 1338 along the top rail 132 toward the base 110 The middle is close together, so that the tip 1338 is just adjacent to both ends of the round shaft 200 to be detected, and the round shaft 200 to be detected is clamped. When the tip 1338 is spliced with the to-be-detected round shaft 200, the stepping motor 1339 on the side of the tip 1338 is rotated by the belt to drive the tip 1338, and the optical measuring instrument 123 measures the data related to the detecting round shaft 200, and feeds the data back to the PC. - PLC Control Center.
在测量过程中,如图11所示,当待检测圆轴200开始转动后,光学测量仪123开始测量待检测圆轴200相应数据。光学测量仪123根据其发出光线被待检测圆轴200遮蔽后产生的阴影得到数据,以与光线垂直段圆轴边缘点作切线,得到阴影间距d。以圆轴边缘与光线各个切点与光线边缘间距测得间距L1或者L2。因为待检测圆轴200旋转至少一周,故可得到数据(d1,d2,…,dn)、(L11,…,L1n)或者(L21,…,L2n),PC-PLC控制中心将数据记录并输送至计算模块。通过对(d1,d2,…,dn)平均值计算待检测圆轴200的外径值。通过计算(L11,…,L1n)或者(L21,…,L2n)中最大值与最小值之差,得出待检测圆轴200的一个轴跳动值,通过计算若干轴跳动值,得出待检测圆轴200的平均跳动值。通过计算(d1,d2,…,dn)中最大值与最小值之差,得出待检测圆轴200的一个真圆度值,通过计算若干真圆度值,得出待检测圆轴200的平均真圆度。上述平均外径值、轴跳动值和真圆度值可保证检测数据的客观性。此外,在PC-PLC控制中心中可设置数据输出形式包括excel或者max、min、ave、cpk工程能力报表使检测人员对待检测圆轴200的数据一目了然。In the measurement process, as shown in FIG. 11, after the round shaft 200 to be detected starts to rotate, the optical measuring instrument 123 starts measuring the corresponding data of the round shaft 200 to be detected. The optical measuring instrument 123 obtains data according to the shadow generated by the light emitted by the circular axis 200 to be detected, and tangentially points with the edge of the circular axis of the vertical section of the light to obtain a shadow spacing d. The distance L1 or L2 is measured by the edge of the circular axis and the distance between each cut point of the light and the edge of the light. Since the round shaft 200 to be detected is rotated for at least one week, data (d1, d2, ..., dn), (L11, ..., L1n) or (L21, ..., L2n) can be obtained, and the PC-PLC control center records and transmits the data. To the calculation module. The outer diameter value of the round shaft 200 to be detected is calculated by averaging (d1, d2, ..., dn). By calculating the difference between the maximum value and the minimum value in (L11, ..., L1n) or (L21, ..., L2n), an axis jump value of the circular axis 200 to be detected is obtained, and by calculating a number of axial runout values, it is determined that the axis is to be detected. The average runout value of the circular shaft 200. By calculating the difference between the maximum value and the minimum value in (d1, d2, ..., dn), a true circularity value of the circular axis 200 to be detected is obtained, and by calculating a plurality of true circularity values, the round axis 200 to be detected is obtained. Average roundness. The above average outer diameter value, axis runout value and true roundness value can ensure the objectivity of the detected data. In addition, the data output form can be set in the PC-PLC control center, including excel or max, min, ave, cpk engineering capability reports, so that the tester can see the data of the detection round shaft 200 at a glance.
待一根待检测圆轴200检测完毕后,步进电机139停止转动,气缸伸缩杆1336伸展或紧缩,与固定块13324上的凸出块13328相互作用,推动基座13323及上方的顶尖1338沿顶尖导轨132往基部110外侧运动,使顶尖1338恰与待检测圆轴200的两端分离即将待检测圆轴200松开,然后将待检测圆轴200取走。由于在检测开始前已预设检测数值分类范围,PC-PLC控制中心可将数据与检测数值范围比较、分类,并将结果输送至显示屏或相应的下料分拣机构150,控制下料分拣机构150完成圆轴分料。After the detection of a round shaft 200 to be detected, the stepping motor 139 stops rotating, and the cylinder telescopic rod 1336 expands or contracts, interacting with the protruding block 13328 on the fixed block 13324, pushing the base 13323 and the top tip 1338 along The top rail 132 moves to the outside of the base 110, so that the tip 1338 is separated from the two ends of the round shaft 200 to be detected, that is, the round shaft 200 to be detected is loosened, and then the round shaft 200 to be detected is taken away. Since the detection value classification range is preset before the start of the detection, the PC-PLC control center can compare and classify the data with the detection value range, and deliver the result to the display screen or the corresponding blanking sorting mechanism 150 to control the blanking point. The sorting mechanism 150 completes the round shaft dispensing.
