[0009] Compared with the traditional mechanical detection method, the staff only needs to install the lock head in the predetermined position, and the detection process is automatically performed, so that the detection efficiency is higher. Meanwhile, the traditional detection method can only determine whether it meets the requirements, and the quantitative detection can be realized through the detection method. The detection pattern on the surface of the display device is analyzed by the detection device, so that the quantitative detection can be realized, and the detection accuracy is higher. By judging the size tolerance of each position of the locking part, the data can be analyzed and summarized, and fed back to the production end to improve the production process and realize high-quality production of the lock head.

DETAILED DESCRIPTION

[0032] The application will be further described below in combination with the drawings and examples.

[0033] The train carriage for transporting goods is positioned and locked between the car body through the lock head. The lock head includes a locking part and a base part. The base part cooperates with the groove at the bottom of the carriage to realize the positioning and locking of the carriage.

[0034] The accuracy of the shape of the base part determines the accuracy of the positioning and locking of the carriage. Therefore, in the last process of lock head production, the shape of the lock head needs to be detected to avoid deviation of the positioning position after the lock head is assembled.

[0035] The traditional shape detection process is manually performed through a detection sheet containing a detection gap. The lock head is fixed on the surface of the detection platform, and the detection sheet is slid relative to the lock head. The lock head with the correct shape can pass through the detection gap, and the smooth passing of the detection sheet through the lock head means that the shape of the lock head meets the positioning requirements.

[0036] The traditional lock head shape detection process needs to be manually performed. The traditional detection method is relatively complicated, and the detection efficiency is limited. At the same time, the accuracy of the lock head outside detection is limited by the accuracy of the detection sheet and the standard degree of manual operation of the detection personnel. The accuracy of the lock head shape detection cannot reach a high level.

[0037] In order to solve the above problems, with reference to the accompanying Figure 1 -Appendix Figure 8 A lock head shape automatic detection equipment, including a detection housing 200, the detection housing 200 is internally provided with a detection device 500 and a display device 600, through the cooperation of the detection device 500 and the display device 600, the shape of the lock head 100 can be efficiently detected through optical detection, and the specific detection process is as follows.

[0038] First, according to the size of the lock head 100 and the position between the detection device 500, the display device 600 and the lock head 100, the detection pattern on the surface of the display device 600 is determined according to the projection relationship, and is enlarged or reduced according to the standard size of the lock head 100; the detection device 500 is located on the other side to analyze the pattern, and judge whether the outline of the detection pattern can be observed. If the detection device 500 cannot detect the outline of the detection pattern of the display device 600, it means that the size of the lock head 100 is too large and does not meet the production requirements; if the outline of the detection pattern observed by the detection device 500 is too large and exceeds the threshold value, it means that the size of the lock head 100 is too small and also does not meet the production requirements.

[0039] Through the above detection method, by using the relationship of image projection, the lock head 100 is placed between the detection device 500 and the display device 600, which can quickly detect the shape of the lock head 100 and quickly judge whether the size of the lock head 100 meets the production requirements, thereby improving the efficiency and accuracy of the detection of the lock head 100.

[0040] After the detection of the first side of the locking part 120 is completed, the whole lock head 100 is rotated by 90°, so that the second side of the locking part 120 is located between the detection device 500 and the display device 600, and the quick detection of the shape of the second side of the locking part 120 is realized. During this detection process, the image displayed by the display device 600 is adaptively adjusted.

[0041] It should be noted that the display device 600 can be a display screen, which displays two detection patterns of different colors (with large color contrast) on the surface of the display device 600, and the shape of the locking part 120 is judged by judging the blocking of the detection pattern.

[0042] Compared with the traditional mechanical detection method, the worker only needs to install the lock head 100 in the predetermined position, and the detection process is automatically performed, so that the detection efficiency is higher. At the same time, the traditional detection method can only judge whether it meets the requirements, and the detection method can realize quantitative detection. The detection pattern on the surface of the display device 600 is analyzed by the detection device 500, so that quantitative detection can be realized, the detection accuracy is higher, the size tolerance of each position of the locking part 120 is judged, the data can be analyzed and summarized, and feedback is provided to the production end, the production process is improved, and high-quality production of the lock head 100 is realized.

Different projection relationships can be formed by adjusting the position of the detection assembly 530, so as to realize efficient detection of different types of lock heads 100. Meanwhile, the position of the detection assembly 530 can be positioned through the detection positioning rod 540, so as to ensure that the detection assembly 530 and the lock head 100 are in a relatively same position for detection, and ensure the accuracy of the image detection result of the detection assembly 530. The detection positioning rod 540 herein is adjusted and set according to the width size of the lock head 100.

[0044] In order to realize the rapid feeding and discharging and rotation control of the lock head 100, the turnover device 400 is further installed in the detection shell 200. The turnover device 400 comprises electric sliding blocks 410 which are in sliding connection with the inner wall of the detection shell 200 and can be linearly moved along the vertical direction under electric control. An electric turnover shaft 420 is installed between the two electric sliding blocks 410 and can rotate around the X axis. A deflection shaft 430 is rotationally connected at the center of the electric turnover shaft 420 and can rotate around the Z axis. Clamping devices 300 for limiting the lock head 100 are installed on both sides of the deflection shaft 430. By controlling the rotation of the electric turnover shaft 420, different lock heads 100 can be controlled to be located in the detection shell 200, so as to realize alternate detection. Meanwhile, the lock head 100 in the detection shell 200 can be controlled to rotate 90° through the deflection shaft 430, so that different sides of the lock head 100 are located between the detection device 500 and the display device 600, and efficient detection is realized.

[0045] The above structure design can quickly adjust the positions of two lock heads 100, so as to meet the requirement of efficient detection of the lock head 100. Meanwhile, the lock head 100 is controlled to be lifted and rotated around the X axis under electric control, and is controlled to be rotated around the Z axis under manual control, so as to realize efficient control of the lock head 100 in the detection process, avoid the design of redundant structures, reduce the operation cost, and meet the requirement of efficient detection of the lock head 100.

[0046] Referring to the accompanying drawings Figure 5 It should be noted that the Z axis is vertically arranged, and the X axis is horizontally arranged.

[0047] Referring to the accompanying drawings Figure 7 , the accompanying drawings Figure 8Further, the clamping device 300 comprises a connecting portion 310 and clamping portions 320 located on both sides of the connecting portion 310, the clamping portions 320 on both sides are matched with the outer side of the base portion 110, and the installation of the whole lock head 100 can be completed by sliding the base portion 110 relative to the clamping portions 320.

[0048] Further, the first locking assembly 321 arranged horizontally and the second locking assembly 322 arranged vertically are installed in the clamping portion 320, the first locking assembly 321 and the second locking assembly 322 are arranged in an extendable and retractable manner, the position of the lock head 100 can be adjusted by adjusting the extension length of the first locking assembly 321 on both sides.

[0049] The second locking assembly 322 herein comprises four matrix arranged telescopic ends, the deflection of the base portion 110 towards the first direction can be adjusted by adjusting the telescopic ends on the front and back sides, and the deflection of the base portion 110 towards the second direction can be controlled by adjusting the telescopic ends on the left and right sides.

[0050] Through the above structure design, during the detection of the lock head 100 in the detection shell 200, the deflection position of the lock head 100, especially the locking portion 120, can be adjusted in a small range, the actual installation position of the locking portion 120 after the installation of the base portion 110 deviates by a certain amount can be simulated, the installation position of the base portion 110 can be simulated, and the shape detection under different installation conditions can be realized according to the shape detection results of the detection device 500 and the display device 600, and whether the locking portion 120 meets the installation requirements under the limit condition is further judged.

[0051] It should be further pointed out that the second locking assembly 322 herein is located on the side close to the locking portion 120, after the lock head 100 and the clamping device 300 are turned over by 180°, the second locking assembly 322 is located at the bottom, the second locking assembly 322 is combined with the gravity of the lock head 100, and efficient adjustment can be realized; and through the design of the extendable and retractable first locking assembly 321 and the second locking assembly 322, the first locking assembly 321 and the second locking assembly 322 are controlled to be in the retracted state, the base portion 110 can be quickly slid into the predetermined position, and quick installation can be realized; and the first locking assembly 321 and the second locking assembly 322 are controlled to be extended, the surface of the base portion 110 can be abutted tightly, the stability of the whole structure of the lock head 100 during the turning over and detection process is ensured, the normal shape detection of the locking portion 120 is ensured, and the accuracy of the detection structure is further ensured.
