Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1 、 2 As shown in Figures 3, 4, 5, and 6, the present utility model provides a technical solution: a main housing detection device, including: a bottom plate 1 made of iron; a center positioning shaft 20 is installed on the top of the bottom plate 1 through bolts for positioning from the inside of the workpiece; positioning grooves are arranged on the top of the bottom plate 1, and a plurality of positioning grooves are provided and arranged concentrically with the center positioning shaft 20. Measuring parts for measuring distances are symmetrically arranged at the top of the positioning grooves; a telescopic part is arranged above the bottom plate 1. The telescopic part includes a limit slide bar 4 and a telescopic rod. The end of the support pillar 2 and the output end of the telescopic rod are both fixedly connected with a detection head 6. The detection head 6 is provided with a second pressure sensor 9 for the aperture.

[0027] It should be noted that the present utility model is provided with a processor, a controller, and a display. The processor is connected to each sensor. The main housing is a circular tube structure on the outside and is provided with a plurality of holes and three protruding mounting parts, such as Figure 5As shown, the circular tube structure is sleeved outside the central positioning shaft from top to bottom, and the outward protruding mounting parts are respectively inserted into the corresponding positioning slots. In this way, the position of the center of the shell is determined by the central positioning shaft 20. The three mounting parts cooperate with the positioning slots to achieve the angle, so that the holes at each position correspond to the detection heads 6 of the telescopic rods. The detection heads 6 are driven by the telescopic rods to be inserted into the holes, and the pressure value data is detected by the second pressure sensors 9 on the upper and lower sides to determine whether it is qualified by judging whether the pressure value data is within the preset range value.

[0028] Please refer to Figure 1 、 2 As shown in FIGS. 3 and 6, the positioning slots include a first positioning card slot 7, a second positioning card slot 12 and a third positioning card slot 16. The first positioning card slot 7, the second positioning card slot 12 and the third positioning card slot 16 are all vertically and fixedly connected to the top of the bottom plate 1 along the length direction. The second positioning card slot 12 is fixedly connected with a positioning rod 13 on one side of the central positioning shaft 20.

[0029] It should be noted that the heights of the three mounting parts on the outer side of the main shell of the present invention are different and are distributed at different angles. The first positioning card slot 7, the second positioning card slot 12 and the third positioning card slot 16 are all rectangular frames with openings on the sides. Their heights are different and are respectively matched and positioned with the corresponding mounting parts, which is convenient for determining the angle of the main shell during detection and for corresponding the opened holes with the detection heads 6. There is a gap between the positioning rod 13 and the central positioning shaft 20. When the main shell is deformed or has different thicknesses, the main shell cannot be inserted into the gap between the positioning rod 13 and the central positioning shaft 20. In this way, the outer shape of the main shell can be preliminarily detected.

[0030] Please refer to Figure 1 、 2 As shown in FIGS., the measuring part includes a second infrared rangefinder 19 and a first infrared rangefinder 17. The first infrared rangefinder 17 and the second infrared rangefinder 19 are symmetrically arranged about the center of the central positioning shaft 20. The bottom of the second infrared rangefinder 19 is fixedly connected with a bracket 18, and the bracket 18 is fixedly connected with the bottom plate 1. The first infrared rangefinder 17 is fixedly connected to the top of the third positioning card slot 16.

[0031] It should be noted that the first infrared rangefinder 17 and the second infrared rangefinder 19 of the present invention are located on the symmetric sides of the main shell. After the outer shape of the main shell is preliminarily positioned by the central positioning shaft 20 and the positioning rod 13, the first infrared rangefinder 17 and the second infrared rangefinder 19 measure the distance between the outer side of the main shell and the measuring point. In this way, by judging whether the measured distance is within the preset value range, it is determined whether the outer diameter of the workpiece side is within the preset range and whether it is qualified.

[0032] Please refer to Figure 1 、 2As shown in Figures 3, 6, a support column 2 is fixedly connected to the top of the bottom plate 1. A limit slide bar 4 is slidably installed in the middle of the support column 2. The fixed end of the air cylinder 3 is fixedly connected to the limit slide bar 4 through a connecting plate. The output end of the air cylinder 3 is fixedly connected to the support column 2. The telescopic rod includes a second electric push rod 10, a fifth electric push rod 11, a third electric push rod 15 and a first electric push rod 8. Both the second electric push rod 10 and the fifth electric push rod 11 are located above the second positioning slot 12. Both the second electric push rod 10 and the fifth electric push rod 11 are fixedly connected to the bottom plate 1 through a support frame. The third electric push rod 15 is fixedly connected to the top of the bottom plate 1 in between, and the third electric push rod 15 is located on one side close to the third positioning slot 16. The first electric push rod 8 is inserted in the middle of the first positioning slot 7.

[0033] It should be noted that the present utility model is provided with multiple detection heads 6, and the diameters are different according to the sizes of the corresponding measurement holes. After the main housing is positioned, the air cylinder 3 drives the limit slide bar 4 to move through the connecting plate by telescoping, so that the detection head 6 at the end of the limit slide bar 4 contacts the corresponding hole. At the same time, the second electric push rod 10, the fifth electric push rod 11, the third electric push rod 15 and the first electric push rod 8 are all located at the center of the hole position, and they drive the corresponding detection heads 6 to contact the corresponding holes. The position and size of the hole are judged whether they are within the preset range by the pressure value caused by the contact between the inner wall of the hole side and the second pressure sensor 9.

[0034] Please refer to Figure 4 As shown in the figure, the detection head 6 includes a connecting column 14. Second pressure sensors 9 are symmetrically embedded and installed on the outside of the connecting column 14. One end of the connecting column 14 is fixedly connected with a first pressure sensor 5.

[0035] It should be noted that the first pressure sensor 5 of the present utility model is at the end of the connecting column 14. When the first pressure sensor 5 is subjected to resistance and generates pressure, it indicates that the position is not the hole position and the vacant position is unqualified. The second pressure sensor 9 is installed on the outside of the connecting column 14 and can measure the pressure change generated when inserted into the hole in real time. When the connecting column is inserted into the hole, the contact between the hole wall and the connecting column will cause a pressure change. If the diameter of the hole meets the predetermined standard, the pressure measured by the sensor will remain within a normal range. If the hole diameter is too large or too small, the pressure value will deviate significantly from this range, so that the actual diameter of the hole can be inferred. The sensor measures the pressure on both the left and right sides at the same time. By comparing the pressure values on both sides, it can be judged whether the hole is in the center position. If the pressure difference between the two sides is large, it means that the connecting column fails to be exactly in the center of the hole.
