Description

Technical Field

[0001] The invention belongs to the technical field of laser repair, and in particular relates to a mechanical property detection system for parts laser repair. Background Art

[0002] Laser cladding technology refers to a process in which the selected coating material is placed on the surface of the coated substrate in the form of different fillers, and the coating material and a thin layer on the substrate surface are melted at the same time by laser irradiation, and then quickly solidified to form a surface coating with extremely low dilution and metallurgical bonding with the substrate material, thereby significantly improving the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties of the substrate material surface;

[0003] This technology is now commonly used to repair parts. Parts that are worn out due to use can be repaired using this technology, such as various types of roller shafts and conveyor rods.

[0004] In the process of testing the mechanical properties of parts, people mostly use stretching, torsion, compression, impact, hardness, stress relaxation, fatigue and other methods to conduct testing. This process is relatively complicated and basically ignores the fundamental reason for the unqualified mechanical properties of parts - the existence of honeycombs and holes on the surface or inside of the repaired parts. Whether there are small honeycombs and holes on the repaired surface or inside of the parts directly affects the results of various performance tests of the parts. If the existence of honeycombs and holes on the surface and inside of the parts is tested, then the items of other tests can inevitably be relatively reduced, thereby achieving the effect of improving efficiency and detection accuracy.

[0048] Among them, the delay mechanism includes a second gear 22, the top surface of the device frame 1 is connected to the second gear 22 through a bearing, the top surface of the device frame 1 is provided with a slide groove, the device frame 1 is slidably connected to a sliding member 23 through the slide groove provided on the top surface, the top surface of the second gear 22 is fixedly connected to an incomplete gear 24, the sliding member 23 is sleeved on the surface of the incomplete gear 24, the interior of the sliding member 23 is equidistantly and symmetrically provided with tooth grooves, the sliding member 23 is meshed with the incomplete gear 24 through the tooth grooves provided inside, the top surface of the sliding member 23 is symmetrically and fixedly connected with a linkage wire 32, one end of the linkage wire 32 passes through the surface of the detection chamber 31 and extends to the interior of the detection chamber 31.

[0049] The top surface of the device frame 1 is symmetrically connected to rollers 26 via bearings, and the surface of the rollers 26 is tangent to the adjacent surface of the moving beam 27.

[0050] Among them, the interior of the detection chamber 31 is symmetrically connected to the first roller 33 through a rotating shaft, one end of the detection frame 35 is connected to the second roller 36 through a rotating shaft, the surface of the detection arc piece 40 is equidistantly connected to the contact wheel 42 through the rotating shaft, the surface of the contact wheel 42 is glued with a rubber pad, and the surface of the rubber pad is provided with anti-slip grooves.

[0051] In this embodiment, the user first starts the first electric telescopic rod 14, and the first electric telescopic rod 14 extends to a position higher than the top of the detection chamber 31, and then inserts the repaired roller shaft into the latch hole 13, and then starts the first electric telescopic rod 14 again, so that the docking seat 15 on the first electric telescopic rod 14 contacts the top of the roller shaft, thereby fixing the roller shaft;

[0052] At this time, the motor 2 can be started, and the output end of the motor 2 drives the third gear 44 to rotate. During the rotation process, the third gear 44 will drive the meshed first gear 3 to rotate synchronously. During the rotation process, the first transmission roller 5 connected to the surface of the first gear 3 follows its synchronous movement and embeds into the groove on the surface of the mounting plate 4 during the movement, thereby synchronously driving the mounting plate 4 to rotate a certain angle, and then another group of first transmission rollers 5 on the first gear 3 are then embedded in the groove on the surface of the mounting plate 4 due to the transmission effect of the first gear 3, and drive the mounting plate 4 to rotate a certain angle again, and the two groups of second transmission rollers 7 on the connecting plate 6 on the surface of the third gear 44 are synchronously driven to rotate, and each time they are embedded in the groove on the surface of the mounting plate 4, the mounting plate 4 is driven to rotate and return to the initial position, so that the above-mentioned movement process causes the roller shaft fixed by the mounting seat 8 on the mounting plate 4 to perform two circular motions with the same rotation angle and then perform a reset motion;

[0053] During this process, the output end of the motor 2 will synchronously drive the incomplete gear ring 11 sleeved on the output end surface to rotate. During the rotation process, the incomplete gear ring 11 will drive the moving part 10 in the T-shaped plate 9 meshing with it to make a horizontal reciprocating motion in the T-shaped plate 9, so that the latch rod 12 on the moving part 10 will be embedded in the latch hole 13 opened on the surface of the mounting seat 8, and the mounting plate 4 will be temporarily locked;

[0054] At the same time, the transmission roller shaft 17 sleeved on the surface of the output end of the motor 2 will rotate through the transmission belt 20 transmission shaft 18 on the transmission roller shaft 19, and the gear assembly 21 connected to the shaft 18 will be synchronously driven to rotate. During the rotation of the gear assembly 21, the passive rod 25 on its surface rotates along with it. During the movement, the passive rod 25 will move the transmission member 28 at the connection point on the top surface of the device frame 1, so that the transmission member 28 drives the moving beam 27 to move between the rollers 26 through the positioning rod 29 during the rotation. Then, further rotation of the gear assembly 21 will cause another group of passive rods 25 on its surface to move the guide rod 30, so that the moving beam 27 moves and resets. During the first movement of the moving beam 27, it will drive the detection chamber 31 connected to it to approach the mounting seat 8, so that the detection chamber 31 covers the surface of the roller shaft fixed on the mounting seat 8.

[0055] During the rotation of the gear assembly 21, the second gear 22 meshed with it will be synchronously driven to rotate, and the incomplete gear 24 connected to the second gear 22 rotates with it and drives the sliding member 23 meshed with it to slide back and forth along the slide groove opened on the top surface of the device frame 1, and during the sliding process, it will pull the linkage wire 32 to extend from and into the interior of the detection chamber 31;

[0056] When the detection chamber 31 is covered in front of the surface of the roller shaft, the movement of the sliding member 23 will provide the linkage wire 32 with a certain length required for the movement span, thereby avoiding the situation in which the plug-in 34 inside the detection chamber 31 has been driven to move closer to each other before reaching the two sides of the roller shaft;

[0057] Then, when the sliding member 23 rotates to the limit, the linkage wire 32 is tightened, and the further movement of the detection chamber 31 drives the plug-in 34 inside it to move. The plug-in 34 will synchronously contact the detection frame 35 during the movement, so that the detection arc piece 40 on the detection frame 35 extends from the inside of the detection chamber 31 and contacts the surface of the roller shaft. Then, the second electric telescopic rod 38 can be started to extend and contract, so that the detection arc piece 40 can rotate on the surface of the roller shaft, so that the detection arc plate 39 can move more smoothly on the surface of the detection target, and the single-chip microcomputer 43 and the micro air pump 52 are started during the movement to detect the detection target. If more accurate detection is required, the user only needs to rotate the detection target in the mounting seat 8 for a certain angle after the current detection is completed and then check it again;

[0058] The first roller 33, the second roller 36 and the contact wheel 42 are all arranged to avoid excessive friction and wear of the components on their respective contact surfaces due to contact, and the three can rotate with a small friction force to assist the transmission of the components that transmit transmission to each other.

[0059] It should be noted that the user can change the proportions of the components on the device to adapt it to the detection of various roller shafts and other rod-shaped parts within a certain range.

[0060] Among them, the mounting plate 4 is connected to the device frame 1 through a damping bearing.

[0061] This arrangement can prevent the mounting plate 4 from rotating excessively due to inertia during the transmission rotation process.

[0062] The microcontroller 43 is internally deployed with the following modules forming a system electrically integrated on the same circuit board, including:

[0063] The control module 45 is used to control the opening and closing of the single chip microcomputer 43 and the micro air pump 52;

[0064] The acquisition module 46 is used to acquire the airflow resistance when the airflow ejected from the output end of the micro air pump 52 contacts the detection target surface;

[0065] A recording module 47, used to record data collected by the collection module 46;

[0066] A marking module 48, used for marking the position of the detection arc piece 40 currently located on the detection target surface;

[0067] A setting module 49 is used to set a detection target error allowable threshold;

[0068] A comparison module 50 is used to compare the data collected by the collection module 46 with the allowable error threshold set by the setting module 49;

[0069] The determination module 51 is used to obtain the comparison result of the comparison module 50. If the data value collected by the acquisition module 46 is within the allowable error threshold range, the detection target is qualified, otherwise it is unqualified.

[0070] When the system is running, the control module 45 controls the system and the micro air pump 52 to start when the contact wheel 42 on the detection arc sheet 40 is in contact with the surface of the detection target, and obtains the airflow resistance when the airflow ejected from the output end of the micro air pump 52 contacts the detection target surface through the acquisition module 46. If there are some honeycombs and holes on the surface of the detection target that are imperceptible to the human eye, the airflow resistance will change. At this time, while the data collected by the acquisition module 46 is recorded by the recording module 47, the error allowable threshold set by the setting module 49 is compared with the change value of the data value collected by the acquisition module 46 through the comparison module 50. Finally, the judgment module 51 determines whether the current detection target is qualified. If it is unqualified, the marking module 48 is used to mark the detection target and its unqualified position for the user to know.

[0071] On the other hand, refer to Figure 6 An electric slide rail 53 is installed inside the detection chamber 31, and an ultrasonic detector 54 is slidably connected inside the electric slide rail 53. When the detection target is in the detection chamber 31 for detection, the electric slide rail 53 can also be started to drive the ultrasonic detector 54 to move up and down reciprocatingly inside it, so that the ultrasonic detector 54 emits ultrasonic waves and continuously contacts the surface of the detection target to generate echoes. The user can configure a display on the surface of the device to electrically connect the display to the ultrasonic detector 54 to receive the ultrasonic echo data measured by the ultrasonic detector 54 in real time. The ultrasonic echo data can be used to further evaluate the mechanical properties of the detection target after repair.
