实施例：Example:

请参阅图1～图4，本发明优选实施例中的O型密封油槽的高度检测装置包括定位组件1和测量组件3，由定位组件1完成工件2的定位，也即是实现O型密封油槽201的定位。之后，通过测量组件3在定位组件1上的定位放置，实现测量组件3与O型密封油槽201的定位和测量。Please refer to FIGS. 1 to 4 , the height detection device of the O-shaped sealed oil groove in the preferred embodiment of the present invention includes apositioning assembly 1 and ameasurement assembly 3 , and thepositioning assembly 1 completes the positioning of theworkpiece 2 , that is, the realization of the O-shaped sealed oil groove. 201 positioning. After that, by positioning and placing the measuringassembly 3 on thepositioning assembly 1, the positioning and measurement of the measuringassembly 3 and the O-shaped sealingoil groove 201 are realized.

具体而言，优选实施例中的定位组件1如图1中所示，其包括呈板状结构的底板101，该底板101的一端为工件定位端，其顶面上设置有多个销柱结构，用于实现工件2的定位和限位；相应地，底板101的另一端为测具定位端，其顶面上成对设置有等高块102，两等高块102进一步优选平行间隔设置在底板101顶面上的横向两侧，用于测量组件3的放置和定位。实际设置时，等高块102自测具定位端延伸至工件定位端的销柱结构两侧，使得工件2对应定位后，其O型密封油槽201可以位于两等高块102之间。Specifically, as shown in FIG. 1 , thepositioning assembly 1 in the preferred embodiment includes abottom plate 101 in a plate-like structure, one end of thebottom plate 101 is a workpiece positioning end, and a plurality of pin structures are provided on the top surface of thebottom plate 101 . , is used to realize the positioning and limiting of theworkpiece 2; Correspondingly, the other end of thebottom plate 101 is the positioning end of the measuring tool, and the top surface thereof is provided with equal height blocks 102 in pairs, and the two equal height blocks 102 are further preferably arranged in parallel and at intervals. The two lateral sides on the top surface of thebase plate 101 are used for the placement and positioning of themeasurement assembly 3 . In actual setting, thecontour block 102 extends from the positioning end of the measuring tool to both sides of the pin structure at the positioning end of the workpiece, so that after theworkpiece 2 is positioned correspondingly, its O-shaped sealingoil groove 201 can be located between the two contour blocks 102 .

更详细地，优选实施例中的销柱结构包括至少3个支撑柱105，用于支撑工件2的底部；优选地，优选实施例中的支撑柱105为如图1中所示的间隔设置的3个，分别用于支撑工件2的三角。同时，在支撑柱105的外侧设置有多个限位柱104，例如图1中间隔设置的5个，用于对工件2的外周侧壁面进行抵接限位，防止工件2在检测过程中发生偏移，保证检测过程的准确性。实际实质是，各支撑柱105设置在多个限位柱104所围区域的内侧，以此保证支撑柱105对工件2的可靠支撑以及限位柱104对工件2的准确限位。In more detail, the pin structure in the preferred embodiment includes at least threesupport columns 105 for supporting the bottom of theworkpiece 2 ; preferably, thesupport columns 105 in the preferred embodiment are spaced as shown in FIG. 1 . 3, respectively used to support the triangle ofworkpiece 2. At the same time, a plurality oflimit columns 104 are arranged on the outer side of thesupport column 105, for example, five are arranged at intervals in FIG. 1, which are used to limit the contact of the outer peripheral side wall surface of theworkpiece 2 to prevent theworkpiece 2 from occurring during the detection process. offset to ensure the accuracy of the detection process. The actual essence is that eachsupport column 105 is disposed inside the area surrounded by the plurality oflimit columns 104 , so as to ensure reliable support of theworkpiece 2 by thesupport columns 105 and accurate limit of theworkpiece 2 by thelimit columns 104 .

相应地，对应工件2上的定位孔设置有定位销106，如图1中所示的两个，用于从底部嵌入工件2上的定位孔中，对工件2的位置进行进一步地定位。Correspondingly, the positioning holes on theworkpiece 2 are provided withpositioning pins 106 , such as two shown in FIG. 1 , for inserting into the positioning holes on theworkpiece 2 from the bottom to further locate the position of theworkpiece 2 .

此外，为了实现测量组件3在测量时的校准，在两等高块102之间设置有至少一处标准柱103，其设置在底板101上后，顶面距底板101顶面、距等高块102的顶面的距离为已知的固定值，以此来实现测量组件3测量前的校准，保证测量结果的准确性。In addition, in order to realize the calibration of the measuringassembly 3 during measurement, at least onestandard column 103 is provided between the two equal-height blocks 102 . The distance of the top surface of 102 is a known fixed value, so as to realize the calibration of themeasurement component 3 before measurement, and to ensure the accuracy of the measurement result.

显然，不难理解的是，优选实施例中标准柱103的设置位置处于销柱结构的最外侧，确保工件2限位放置于销柱结构上后，标准柱103位于不被工件2所遮挡的位置，如图4中所示。Obviously, it is not difficult to understand that in the preferred embodiment, the setting position of thestandard column 103 is at the outermost side of the pin structure. After ensuring that theworkpiece 2 is placed on the pin structure in a limited position, thestandard column 103 is located in a place not blocked by theworkpiece 2. position, as shown in Figure 4.

进一步地，对于优选实施例中的销柱结构而言，其高度形式如图2中所示。其中，支撑柱105在底板101上设置后的竖向尺寸L₁小于限位柱104的竖向尺寸，使得工件2在支撑柱105上设置后，限位柱104的顶部可突出工件2的底面。同时，标准柱103的竖向尺寸L₂不小于支撑柱105的竖向尺寸，并使得工件2在定位组件1上设置后其O型密封油槽201的底部高度大于标准柱103的竖向高度。当然，显而易见地，标准柱103的竖向尺寸低于两等高块102的竖向尺寸L₃。另外，位于两等高块102之间的限位柱104的高度也不大于等高块102的高度，以此避免发生干涉。Further, for the pin structure in the preferred embodiment, its height form is as shown in FIG. 2 . The vertical dimension L1_of thesupport column 105 after being set on thebottom plate 101 is smaller than the vertical dimension of thelimit column 104, so that after theworkpiece 2 is set on thesupport column 105, the top of thelimit column 104 can protrude from the bottom surface of theworkpiece 2 . At the same time, the vertical dimension L₂ of thestandard column 103 is not smaller than the vertical dimension of thesupport column 105 , so that the bottom height of the O-seal oil groove 201 of theworkpiece 2 after being set on thepositioning assembly 1 is greater than the vertical height of thestandard column 103 . Of course, it is obvious that the vertical dimension of thestandard column 103 is lower than the vertical dimension L₃ of the two equal-height blocks 102 . In addition, the height of the limitingcolumn 104 located between the two equal-height blocks 102 is not greater than the height of the equal-height blocks 102, so as to avoid interference.

如图3中所示，优选实施例中的测量组件3如图3中所示，其包括呈长条形块状结构的表座301，其长度不小于两等高块102之间的距离，使得表座301的两端可对应搭放在两等高块102上。同时，优选实施例中的表座301为耐变形和耐磨损的金属块结构，其重量较大，以此来保证其两端放置于两等高块102上工作时的稳定性，避免测量过程中表座301的端部抬起，为百分表302的测量提供可靠的基准。As shown in FIG. 3 , themeasurement assembly 3 in the preferred embodiment is shown in FIG. 3 , which includes ameter base 301 in the form of a long block-shaped structure, the length of which is not less than the distance between the two equal-height blocks 102 , The two ends of thewatch base 301 can be placed on the two equal-height blocks 102 correspondingly. At the same time, thewatch seat 301 in the preferred embodiment is a metal block structure that is resistant to deformation and wear, and its weight is relatively large, so as to ensure the stability of its two ends when it is placed on the two equal-height blocks 102 and avoid measuring During the process, the end of thewatch seat 301 is lifted to provide a reliable reference for the measurement of thedial indicator 302 .
