DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described in detail below in conjunction with specific embodiments: Example

[0030] See also Figure 1-9A sheet metal thickness detection device includes a detection table 1, a support plate 2 for supporting a sheet metal 46 is fixed on the detection table 1, the sheet metal 46 is fixed on the detection table 1 by a clamp, door frames 3 are fixed at both ends of the detection table 1, each door frame 3 is fixed with a longitudinal guide rod 17, a longitudinal slide 12 is slidably mounted on the longitudinal guide rod 17, a transverse strip 5 is fixed on the longitudinal slide 12, a transverse slide 8 is slidably mounted on the transverse strip 5, a laser thickness measurement module 26 is installed at the bottom of the transverse slide 8, a motor 7 is fixed on the transverse slide 8, and the motor 7 The upper drive is connected with a transverse sliding assembly, which is used to drive the transverse slide 8 to reciprocate laterally. The transverse slide 8 is equipped with a longitudinal sliding assembly for driving the longitudinal slide 12 to slide step by step relative to the longitudinal guide rod 17. A bogie 28 is rotatably installed at the bottom of the transverse slide 8, and an extension frame 29 is slidably installed on the bogie 28. A force roller 9 for pressing the sheet metal 46 is rotatably installed on the extension frame 29. A connecting spring 30 is fixed between the extension frame 29 and the bogie 28. A steering assembly for driving the bogie 28 to deflect is installed on the transverse strip 5.

[0031] When the thickness of the sheet metal part 46 is tested by the device, the sheet metal part 46 is placed on the support plate 2, and the sheet metal part 46 is fixed on the testing platform 1 by the fixture processing, so as to ensure the stability of the sheet metal part 46 during the testing process. The lateral sliding assembly drives the lateral sliding carriage 8 and the laser thickness measuring module 26 installed thereon to move laterally relative to the sheet metal part 46, so as to detect different positions of the sheet metal part 46, thereby improving the comprehensiveness of the detection of the sheet metal part 46.

[0032] Specifically, the transverse sliding assembly includes a rotating shaft 21 rotatably mounted on the transverse sliding frame 8, a traveling gear 22 is coaxially fixed on the rotating shaft 21, a rack 6 meshing with the traveling gear 22 is fixed on the transverse strip 5, and a transmission assembly is installed between the rotating shaft 21 and the motor 7. The transverse sliding assembly also includes a limit column II40 vertically slidably mounted on the transverse sliding frame 8, a positioning friction block 39 that is in frictional contact with the rotating shaft 21 is fixed on the top of the limit column II40, a spring ring I38 is fixed between the positioning friction block 39 and the transverse sliding frame 8, and the positioning friction block 39 can be in friction contact with the rotating shaft 21 under the elastic action of the spring ring I38, so as to realize temporary positioning of the rotating shaft 21 during the non-rotating period.

[0033] Among them, the transmission assembly includes a transmission sleeve 23 slidably sleeved on the rotating shaft 21, and a clamping strip 41 fixed on the rotating shaft 21 is slidably installed on the inner wall of the transmission sleeve 23. The motor 7 is drivingly connected to an incomplete bevel gear 19, and two reversing bevel gears 20 alternately meshing with the incomplete bevel gear 19 are fixedly sleeved on the transmission sleeve 23.

[0034] The motor 7 is arranged to drive the incomplete bevel gear 19 to rotate, and the incomplete bevel gear 19 intermittently meshes with the reversing bevel gear 20, so that the reversing bevel gear 20 drives the transmission sleeve 23 to rotate, and the transmission sleeve 23 drives the rotating shaft 21 to rotate through the clamping strip 41. At this time, the traveling gear 22 rotates and meshes with the rack 6 for transmission, so that the transverse slide 8 drives the laser thickness measurement module 26 to move horizontally and perform multi-point automatic detection on different positions of the sheet metal part 46.

[0035] In addition, a reversing transmission frame 24 is slidably mounted on the transverse slide 8, a transmission sleeve 23 is rotatably mounted on the reversing transmission frame 24, two ends of the reversing transmission frame 24 are provided with inclined surfaces I33 and II34, respectively, and two upright posts 13 corresponding to the inclined surfaces I33 and II34 are mounted on the transverse strip 5. An extension plate 25 located below the reversing transmission frame 24 is fixed on the transverse slide 8, two linearly distributed V-grooves 42 are provided on the extension plate 25, a positioning block 43 that is adapted to the V-grooves 42 is vertically slidably mounted on the reversing transmission frame 24, and a push spring 44 is fixed between the positioning block 43 and the reversing transmission frame 24.

[0036] Through the above arrangement, the traverse slide 8 drives the reversing transmission frame 24 to move horizontally. When the inclined surface I33 abuts against one of the columns 13 or the inclined surface II34 abuts against the other column 13, the reversing transmission frame 24 slides relative to the traverse slide 8. At this time, the transmission sleeve 23 drives the reversing bevel gear 20 to slide, so that the incomplete bevel gear 19 switches from meshing with one of the reversing bevel gears 20 to meshing with the other reversing bevel gear 20. The above switching process realizes the change of the rotation direction of the running gear 22, thereby realizing the automatic reciprocating movement of the laser thickness measurement module 26 and fully detecting the sheet metal part 46. In the above switching process, the positioning plug 43 is plugged and adapted with the corresponding V-groove 42, ensuring the stable meshing transmission of the incomplete bevel gear 19 and the reversing bevel gear 20.

[0037] In addition, the longitudinal sliding assembly of the device includes a push plate I10 and a push plate II11 fixed on both sides of the transverse slide 8, and a plurality of linearly equidistantly distributed wedge surfaces I4 and wedge surfaces II18 are respectively provided on the two door frames 3. The push plate I10 is opposite to the wedge surface I4, and the push plate II11 is opposite to the wedge surface II18.

[0038] During the reciprocating motion of the transverse slide 8, the push plate I10 pushes the wedge surface I4 once, the longitudinal slide 12, the transverse slide 8 and the laser thickness measurement module 26 move longitudinally once, the push plate II11 pushes the wedge surface II18 once, the longitudinal slide 12, the transverse slide 8 and the laser thickness measurement module 26 move longitudinally once, and this process is repeated to realize automatic thickness detection of the sheet metal part 46 at different longitudinal positions, thereby greatly improving the comprehensiveness of the thickness detection of the sheet metal part 46.

[0039] In addition, the longitudinal sliding assembly also includes a limit column I36 slidably mounted on the longitudinal slide 12, and a friction arc disk 16 is fixed on the limit column I36 and is in friction contact with the longitudinal guide rod 17. A spring ring II45 is fixed between the friction arc disk 16 and the longitudinal slide 12. In the process of the longitudinal slide 12 sliding relative to the longitudinal guide rod 17, the friction arc disk 16 is elastically pushed by the spring ring II45 and is in friction contact with the longitudinal guide rod 17, so that the longitudinal slide 12 can temporarily limit its position after each longitudinal movement, thereby ensuring the stability of the laser thickness measurement module 26 in the process of measuring the thickness of the sheet metal part 46. Example

[0040] See also Figure 1-9 On the basis of Example 1, in addition, the steering assembly of the device includes a vertical slider 47 vertically slidably installed on the transverse slide 8, a vertical spring 35 is fixed between the vertical slider 47 and the transverse slide 8, a connecting column 37 is fixed to the upper end of the bogie 28, a connecting rod 31 is hinged between the connecting column 37 and the vertical slider 47, a driving column 32 is fixed on the bogie 28, and a vertical plate I14 and a vertical plate II15 for pushing the driving column 32 are installed on the transverse strip 5, and the vertical plate I14 and the vertical plate II15 are respectively located on both sides of the driving column 32.

[0041] In addition, two side blocks 27 are fixed to the transverse slide 8 and are respectively located on both sides of the connecting column 37 . The two side blocks 27 are used to abut against the connecting column 37 .

[0042] Through the above-mentioned arrangement, when the transverse slide 8 drives the laser thickness measurement module 26 to move horizontally, the force roller 9 presses the sheet metal part 46 to simulate the state of the sheet metal part 46 being subjected to pressure under actual working conditions. After the sheet metal part 46 is subjected to pressure, the laser thickness measurement module 26 measures and detects the thickness of the sheet metal part 46.

[0043] After the driving column 32 moves laterally and pushes against the vertical plate I14 or the vertical plate II15, the bogie 28 rotates and the connecting rod 31 swings, so that the bogie 28 rotates to the front side of the lateral moving direction of the laser thickness measurement module 26, and the force roller 9 presses the sheet metal part 46 for detection. Under the pushing action of the vertical spring 35, the connecting column 37 abuts against the side block 27, achieving an effective positioning effect of the position of the force roller 9, ensuring that the force roller 9 can stably press the sheet metal part 46 after the position is switched, greatly improving the thickness measurement effect of the sheet metal part 46 after being pressed.

[0044] In summary, the present invention realizes the thickness measurement of the transverse area of ​​the sheet metal 46 by reciprocating the transverse sliding assembly, and when the transverse slide 8 moves to the left and right ends, the longitudinal sliding assembly drives the transverse strip 5 and the transverse slide 8 to move longitudinally, so that the laser thickness measurement module 26 can automatically switch positions and perform comprehensive detection of the sheet metal 46, which greatly improves the thickness measurement efficiency and comprehensiveness of the sheet metal 46. The present invention can perform the pressing effect on the sheet metal 46 before detection by the force roller 9 set, and realize the working condition of simulating the external pressure of the sheet metal 46, so that the sheet metal 46 can be tested for thickness after pressurization, and the force roller 9 can be turned and switched according to the change of the sliding direction of the transverse slide 8, so as to ensure that the thickness of the sheet metal 46 is tested after being pressed, and the thickness measurement effect of the sheet metal 46 is significantly improved.
