[0001] The present invention relates to the technical field of mechanical equipment detection, and in particular to an automatic detection system and method for mechanical engineering equipment. Background Art

[0002] With the rapid development of society, the demand for mechanical engineering equipment is increasing. The existing manual inspection can no longer meet social needs. In order to ensure quality and improve overall efficiency, mechanical engineering equipment will be automatically inspected at the end of the production line. The patent document with announcement number CN220751978U discloses an automated offline inspection system for engineering machinery. Although the automated offline inspection system can help engineering equipment adjust to the standard position in the parking position through multi-directional image detection, the actual adjustment process still requires the driver to make fine adjustments based on image feedback, which not only places high demands on the driver, but also cannot control the adjustment time, which is not conducive to improving work efficiency. Summary of the invention

[0003] In view of the fact that the existing technology not only has high operating requirements for the driver, but also cannot control the adjustment time and has low work efficiency, the present invention hopes to provide an automatic detection system and method for mechanical engineering equipment that can automatically adjust mechanical engineering equipment to a standard position, thereby improving work efficiency and being more convenient.

[0004] The present invention provides an automatic detection system for mechanical engineering equipment, comprising two ground rails arranged parallel to each other on the ground, a detection mechanism slidably connected to the ground rails, and an alignment mechanism respectively arranged at the front end and / or rear end of the ground rails;

[0005] The left and right sides of the detection mechanism are provided with laser rangefinder generators; the left and right sides of the mechanical engineering equipment are provided with laser rangefinder receivers corresponding to the laser rangefinder generators;

[0006] The alignment mechanism includes an underground support plate, an electric turntable installed on the underground support plate, and a parking disc installed coaxially with the output shaft of the electric turntable; the parking disc is driven by the electric turntable installed on the underground support plate;

[0007] The center line between the two ground rails intersects with the rotation axes of the two parking discs.

[0008] Furthermore, the detection mechanism includes a sliding base slidably mounted on the ground rail, a self-adjusting frame rotatably mounted on the sliding base, and a detector mounted on the self-adjusting frame; a driver sits in a cab on the detector to control the entire automatic detection system.

[0009] Furthermore, partition walls are arranged opposite to each other on the left and right sides of the underground support plate, and a telescopic rod is fixedly installed on each partition wall, and the telescopic ends of the two telescopic rods are hinged with laser rangefinder receivers; when the mechanical engineering equipment is parked on the parking disc, the laser rangefinder receivers on the left and right sides are attached to the mechanical engineering equipment by adjusting the telescopic rods.

[0010] Furthermore, the telescopic rod includes a fixed sleeve and a movable rod arranged inside the fixed sleeve; one end of the fixed sleeve is fixedly installed on the partition wall, and a blocking ring is arranged on the inner wall of the other end; a rubber block is arranged on the end of the movable rod extending into the fixed sleeve, and the blocking ring is used to limit the rubber block from escaping from the fixed sleeve.

[0011] Furthermore, mirror panels are arranged on the inner sides of the two oppositely arranged partition walls, and the mirror panels are connected to the partition walls via a plurality of elastic connecting members.

[0012] Furthermore, the mirror panel is tilted upward and toward the detector, and the mirror panel includes a soft mirror and a rubber plate arranged behind the soft mirror.

[0013] Furthermore, a lubricating sleeve is arranged at the bottom of the parking disc, an annular groove is arranged at the top of the lubricating sleeve, balls are evenly distributed in the annular groove, and the top of the balls is in contact with the parking disc.

[0014] Furthermore, laser vertical meter receivers are arranged on the front and rear sides of the sliding base, and a laser vertical meter generator is arranged on the front or rear side of the self-adjusting platform; after one of the laser vertical meter receivers is vertically aligned with the laser vertical meter generator, the detection mechanism starts to work.

[0015] Furthermore, blocking frames are respectively arranged at both ends of the floor rail, and touch pressure sensors facing the sliding base are arranged on the blocking frames.

[0016] The present invention also discloses a detection method of an automatic detection system for mechanical engineering equipment, comprising the following steps:

[0017] S1. The laser vertical instrument generator sends out a laser signal. When the laser vertical instrument receiver located on the left side of the sliding base receives the laser signal, it proves that the self-adjusting platform is completely aligned with the sliding base.

[0018] S2. Place the mechanical engineering equipment on the parking disc on one side, adjust the length of the telescopic rod so that the laser rangefinder receiver fits on both sides of the mechanical engineering equipment at a position equal to the width of the two laser rangefinder generators; the laser rangefinder generator emits a laser signal. If the laser rangefinder receiver receives the laser signal, it is determined that the mechanical engineering equipment has been parked, otherwise the driver continues to operate the parking disc to rotate the mechanical engineering equipment to the standard position;

[0019] S3. After the mechanical engineering equipment is adjusted to the standard position, the driver can start to operate the automated inspection system to perform appearance inspection on the mechanical engineering equipment.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings.

[0039] Please refer to Figures 1 to 8 The present invention provides a specific embodiment of an automatic detection system for mechanical engineering equipment. For the convenience of description, Figure 1 As a reference, this patent sets the extension direction of the floor rail 1 as the front-to-back direction, and the extension direction of the telescopic rod 35 as the left-to-right direction.

[0040] like Figure 1-Figure 8 As shown, the automatic detection system for mechanical engineering equipment provided by the present invention includes two ground rails 1 arranged parallel to each other on the ground, a detection mechanism 2 slidably connected to the ground rails 1, and an alignment mechanism 3 respectively arranged at the front end and / or rear end of the ground rails 1.

[0041] In this embodiment, the detection mechanism 2 slides forward or backward on the ground rail 1, and can be used to detect mechanical engineering equipment parked on the front or rear alignment mechanism 3; setting two alignment mechanisms 3 at the front and back can save the waiting time of the detection mechanism 2 when parking multiple times, greatly improving efficiency.

[0042] like Figure 3-Figure 4 As shown, a laser rangefinder generator 21 is arranged on the left and right sides of the detection mechanism 2; a laser rangefinder receiver 22 corresponding to the laser rangefinder generator 21 is arranged on the left and right sides of the mechanical engineering equipment; the detection mechanism 2 includes a sliding base 23 slidably mounted on the ground rail 1, a self-adjusting stand 24 rotatably mounted on the sliding base 23, and a detector 25 mounted on the self-adjusting stand 24; a cab (not shown) is arranged on the self-adjusting stand 24, and a controller of the automatic detection system of the present patent is arranged in the cab, and buttons for controlling the telescopic rod 35, the electric turntable 32, the detector 25, the sliding base 23, etc. are also arranged in the cab; the driver sits in the cab on the detector 25 to control the entire automatic detection system.

[0043] In this embodiment, the driver observes whether the laser rangefinder receiver 22 can receive the laser emitted by the laser rangefinder generator 21 clamped on both sides of the mechanical engineering equipment to determine whether the mechanical engineering equipment on the alignment mechanism 3 is stopped at the standard position; the driver presses the corresponding button to drive the sliding base 23 to slide back and forth on the ground rail 1, and drives the self-adjusting stand 24 to move together, so that the detector 25 can perform a full range of detection on the mechanical engineering equipment. In addition, the positions of the laser rangefinder generator 21 and the laser rangefinder receiver 22 here can also be interchanged, which can achieve the same above-mentioned effect.

[0044] like Figure 1 and Figure 3 As shown, laser vertical meter receivers 26 are arranged on the front and rear sides of the sliding base 23, and a laser vertical meter generator 27 is arranged on the front or rear side of the self-adjusting stand 24; after one of the laser vertical meter receivers 26 is vertically aligned with the laser vertical meter generator 27, the detection mechanism 2 starts to work.

[0045] In this embodiment, when it is necessary to detect the mechanical engineering equipment behind, the driver drives the self-adjusting platform 24 to rotate by pressing a button. At this time, the laser vertical meter generator 27 located on one side of the self-adjusting platform 24 emits a laser. The driver observes whether the laser vertical meter receiver 26 located on one side of the sliding base 23 receives the laser to determine whether the positions of the self-adjusting platform 24 and the sliding base 23 are vertically aligned. If aligned, the rotation is stopped. At this time, the detection mechanism 2 can detect the mechanical engineering equipment behind; the laser vertical meter receiver 26 is set on both sides, which is more convenient for laser alignment; the self-adjusting platform 24 is a rotating structure, which can make the detection of mechanical engineering equipment more convenient and efficient, saving the waiting time of the detection mechanism 2 when parking multiple times, and greatly improving the efficiency. In addition, the positions of the laser vertical meter generator 27 and the laser vertical meter receiver 26 can also be interchanged, which can achieve the same above-mentioned effect.

[0046] like Figure 4-Figure 6 As shown, the alignment mechanism 3 includes an underground support plate 31, an electric turntable 32 installed on the underground support plate 31, and a parking disc 33 installed coaxially with the output shaft of the electric turntable 32; the parking disc 33 is driven by the electric turntable 32 installed on the underground support plate 31; the center line between the two ground rails 1 intersects with the rotation axis of the two parking discs 33; partition walls 34 are arranged on the left and right sides of the underground support plate 31, and a telescopic rod 35 is fixedly installed on each partition wall 34, and the telescopic ends of the two telescopic rods 35 are hinged with laser rangefinder receivers 22; when the mechanical engineering equipment is parked on the two parking discs 33, the two laser rangefinder receivers 22 are attached to the mechanical engineering equipment by adjusting the telescopic rod 35.

[0047] In this embodiment, the mechanical engineering equipment is first parked on the parking disc 33, and the driver determines whether the mechanical engineering equipment is parked at the standard position. If not, the driver needs to press the corresponding button to drive the electric turntable 32 to rotate the parking disc 33, so as to park the mechanical engineering equipment at the standard position; when placing the mechanical engineering equipment, the telescopic rod 35 needs to be retracted through the driver's button control, and then the mechanical engineering equipment is placed on the parking disc 33 between the two partition walls 34, and then the telescopic rod 35 is extended and adjusted through the driver's button control so that the two laser rangefinder receivers 22 at the end are attached to the mechanical engineering equipment, and the end of the telescopic rod 35 can be rotated and adjusted so that the laser rangefinder receiver 22 can better fit the body of the mechanical engineering equipment.

[0048] like Figure 6-Figure 7As shown, the telescopic rod 35 includes a fixed sleeve 351 and a movable rod 352 arranged inside the fixed sleeve; one end of the fixed sleeve 351 is fixedly installed on the partition wall 34, and a blocking ring 3511 is arranged on the inner wall of the other end; one end of the movable rod 352 extending into the fixed sleeve 351 is provided with a rubber block 3522, and the blocking ring 3511 is used to limit the rubber block 3522 from escaping from the fixed sleeve 351.

[0049] In this embodiment, when the telescopic rod 35 is extended too quickly or with too much force, the rubber block 3522 can be used to clamp the blocking ring 3511 to prevent the movable rod 352 from escaping from the fixing sleeve 351 .

[0050] like Figure 4 and Figure 6 As shown, a mirror panel 36 is arranged on the inner side of the two oppositely arranged partition walls 34, which is inclined upward and toward the detector 25. The mirror panel 36 includes a soft mirror 361 and a rubber plate 362 arranged behind the soft mirror 361. The mirror panel 36 and the partition wall 34 are connected by a plurality of elastic connectors 37.

[0051] In this embodiment, the mirror panel 36 tilted upward and toward the detector 25 can facilitate the driver to quickly observe the bottom of the mechanical engineering equipment on the parking disc 33 through the refraction and reflection of the mirror, and more conveniently help the driver to determine whether all the mechanical engineering equipment is placed on the parking disc 33; the rubber plate 362 behind the soft mirror 361 can prevent the back of the mirror from rubbing against the wall when the elastic connecting member 37 is working, thereby increasing the service life of the mirror panel 36 and reducing wear and tear; multiple elastic connecting members 37 can flexibly adjust the position angle between the mirror panel 36 and the partition wall 34, so that the driver can observe the situation of the mechanical engineering equipment from multiple angles through the mirror panel 36, which plays a role in conveniently and quickly improving efficiency.

[0052] like Figure 5 As shown, a lubricating sleeve 38 is provided at the bottom of the parking disc 33 , and an annular groove is provided at the top of the lubricating sleeve 38 . Balls 39 are evenly distributed in the annular groove, and the top of the ball 39 is in contact with the parking disc 33 .

[0053] In this embodiment, when the driver drives the parking disc 33 to rotate by pressing a button, the lubricating sleeve 38 at the bottom can reduce the friction and wear of the bottom of the parking disc 33 and provide continuous lubrication, and the rolling of the ball 39 increases the force area at the top of the parking disc 33, making the rotation smoother. In addition, marking lines of different colors can be sprayed at the midpoint and edge of the parking disc 33, making the position of the parking disc 33 clearer and easier for the driver to find the correct position for parking.

[0054] like Figure 8As shown, blocking frames 4 are respectively provided at both ends of the floor rail 1 , and touch pressure sensors 5 facing the sliding base 23 are provided on the blocking frames 4 .

[0055] In this embodiment, when the sliding base 23 slides back and forth on the ground rail 1, in order to prevent the sliding base 23 from sliding out of range, a blocking frame 4 and a touch pressure sensor 5 with a buffering function are provided at both ends of the ground rail 1. The touch pressure sensor 5 is electrically connected to the external light / sound and electric alarm component. When the sliding base 23 slides and hits the touch pressure sensor 5, the touch pressure sensor 5 will trigger the external light / sound and electric alarm component due to the pressure, and the external light / sound and electric alarm component will emit a light / sound alarm, which can serve as a timely reminder.

[0056] like Figure 1-Figure 8 As shown, the present invention provides a detection method for an automatic detection system of mechanical engineering equipment, comprising the following steps:

[0057] S1. The laser vertical meter generator 27 emits a laser signal. When the laser vertical meter receiver 26 located on the left side of the sliding base 23 receives the laser signal, it proves that the self-adjusting gantry 24 is completely aligned with the sliding base 23;

[0058] S2. Place the mechanical engineering equipment on the parking disc 33 on one side, adjust the length of the telescopic rod 35, so that the laser rangefinder receiver 22 fits on both sides of the mechanical engineering equipment and is equal to the width of the two laser rangefinder generators 21; the laser rangefinder generator 21 emits a laser signal, and if the laser rangefinder receiver 22 receives the laser signal, it is determined that the mechanical engineering equipment has been stopped, otherwise the driver continues to operate the parking disc 33 to rotate the mechanical engineering equipment to the standard position;

[0059] S3. After the mechanical engineering equipment is adjusted to the standard position, the driver can start to operate the automated inspection system to perform appearance inspection on the mechanical engineering equipment. The driver operates the front end of the detector 25 to rotate around the mechanical engineering equipment to achieve appearance inspection on the mechanical engineering equipment.

[0060] S4. When the alignment mechanism 3 is provided at both the front and rear, the mechanical engineering equipment at the rear is inspected. The driver needs to control the self-adjusting platform 24 to rotate. At the same time, the laser vertical instrument generator 21 emits a laser. The driver observes whether the laser is received by the laser vertical instrument receiver 22 to determine whether the self-adjusting platform 24 and the sliding base 23 are vertically aligned. If the laser is received, the driver controls to stop the rotation. At this time, the detector 25 can inspect the mechanical engineering equipment at the rear.

[0061] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
