下面说明本实用新型的汽车连接支架1检具在检测工件中的工作过程。The working process of the vehicle connection bracket 1 inspection tool of the present utility model in detecting workpieces will be described below.

因为底座2是整个检具设计、安装和调试的基准,操作台3在与底座2固定安装时应先行按同一系列被检测连接支架1要检测的相关尺寸所要求尺寸公差范围进行定位,然后在固定连接,检具安装好后,即可对工件连接支架1进行检测。Because the base 2 is the benchmark for the design, installation and debugging of the entire inspection tool, when the operation table 3 is fixedly installed with the base 2, it should first be positioned according to the dimensional tolerance range required by the relevant dimensions to be detected by the same series of connected brackets 1 to be detected, and then in the After the fixed connection and the inspection tool are installed, the workpiece connection bracket 1 can be inspected.

首先把需要检测的连接支架1放入操作台3的缺口4中,使连接支架1的外轮廓与缺口4的底面和侧面相吻合,然后可用固定压杆6将连接支架1压住,使之不能再移动。做好上述准备后观察被检测连接支架1的外轮廓是不是跟操作台3缺口4底面和缺口4侧面相吻合,若不吻合,则连接支架1不合格,若吻合,可进行下一步检测。为了使检具检测连接支架1的精度尽量提高,检具还包含检测盖板(图中未示意),检测盖板的外轮廓与连接支架1外轮廓吻合,连接支架1放入操作台3缺口4中后,检测盖板可扣合在连接支架1表面,进一步检测连接支架1外轮廓的吻合度。检测完毕后,即可进行下一步检测,检测连接支架1上面孔的孔径、孔距等。First put the connecting bracket 1 to be detected into the notch 4 of the console 3, so that the outer contour of the connecting bracket 1 matches the bottom surface and the side of the notch 4, and then the connecting bracket 1 can be pressed by the fixed pressure rod 6 to make it Can no longer move. After making the above preparations, observe whether the outer contour of the detected connecting bracket 1 matches the bottom surface of the notch 4 of the operating table 3 and the side of the notch 4. If it does not match, the connecting bracket 1 is unqualified. If it matches, the next step of testing can be carried out. In order to improve the accuracy of the inspection tool for detecting the connection bracket 1 as much as possible, the inspection tool also includes a detection cover (not shown in the figure), the outer contour of the detection cover matches the outer contour of the connection bracket 1, and the connection bracket 1 is placed in the gap of the console 3 After step 4, the detection cover can be fastened on the surface of the connecting bracket 1 to further detect the matching degree of the outer contour of the connecting bracket 1 . After the detection is completed, the next step of detection can be carried out, which is to detect the hole diameter and hole distance of the holes on the connecting bracket 1 .

按照需要检测孔取出与之对应的检测棒5,将检测棒5插入需要检测的孔内,使其通过被检测连接支架1上的孔插入与之对应的缺口4底面上的检测开孔中,如果一直插到底这说明此孔的孔距正确,若此时的孔能够与检测棒耦合,则说明此孔的孔径合格,从而说明此孔合格;反之,若其任一项不合格或两项都不合格,则此孔不合格,即此连接支架1不合格。检测完一个孔以后,再取另外口径的检测棒5插入另外需要检测的孔中,采用以上相同的检测方法,直到所有需要检测的孔检测完毕。Take out the detection rod 5 corresponding to it according to the detection hole as required, insert the detection rod 5 in the hole to be detected, and insert it into the detection opening on the bottom surface of the notch 4 corresponding to it through the hole on the connected bracket 1 to be detected, If it is inserted all the way to the bottom, it means that the hole distance of this hole is correct. If the hole at this time can be coupled with the detection rod, it means that the hole diameter of this hole is qualified, thus indicating that this hole is qualified; If they are all unqualified, then this hole is unqualified, that is, this connecting bracket 1 is unqualified. After one hole is detected, another detection rod 5 of another caliber is inserted into another hole to be detected, and the same detection method as above is adopted until all the holes to be detected are detected.

检测完毕后,拔出所有的检测棒5,将其放回到原来的位置,这样可防止检测棒5的丢失,从而方便卸下连接支架1再装上下一个需要检测的连接支架1。依次来检测所有的连接支架1,从而可迅速的完成检测。After the detection is complete, pull out all the detection rods 5 and put them back to their original positions, which can prevent the loss of the detection rods 5, thereby making it easy to unload the connection bracket 1 and then install the next connection bracket 1 that needs to be detected. All the connection brackets 1 are detected sequentially, so that the detection can be completed quickly.

采用这种方式能够迅速准确地对汽车连接支架1进行检测,解决了汽车连接支架1检测难的问题,通过一次定位基准就能检测该件相关尺寸精度是否在要就的尺寸公差范围内,不需要多次定位基准测量和坐标换算,克服了测量效率低难以满足生产要求的缺点,提高了检测工作的效率。In this way, the automobile connecting bracket 1 can be detected quickly and accurately, which solves the problem that the automobile connecting bracket 1 is difficult to detect. It can be detected whether the relevant dimensional accuracy of the part is within the required dimensional tolerance range through one positioning reference, and it is not necessary. Multiple positioning reference measurements and coordinate conversions are required, which overcomes the shortcomings of low measurement efficiency and difficulty in meeting production requirements, and improves the efficiency of inspection work.
