[0014] Preferably, the sliding block is slidably connected to the inner wall of the travel groove.

[0015] Working principle: When using this device to detect the bending degree of the crankshaft in the production process, first place the crankshaft parallel to the center of the positioning plates on both sides through the external feeding device, and then adjust it according to the different lengths of the crankshafts, and turn on the third motor to drive the first connecting rod to rotate. After the first connecting rod rotates, it will pull the pulling plates connected to the second connecting rods on both sides closer to the middle, so that the position of the positioning plate is aligned with the center axis position of both ends of the crankshaft, and then turn on the second motor, and drive the screw to rotate through the output of the second motor, so as to drive the adjustment block to gradually pull the connection position of the middle block through the threaded connection. During the movement of the middle block, the distance between the support rod and the extension rod will be extended, thereby changing multiple moving plates so that the locking block gradually contacts with both sides of the crankshaft, thereby completing the fixation.

[0016] At this time, the staff can open the hand-tightening bolt, select the crankshaft detection position by adjusting the position of the sliding block, and make the sensor wheel completely contact the crankshaft position to be detected. An inductive displacement sensor is installed inside the crankshaft to perform circumference statistics on the measured crankshaft end, and when the curvature changes, it will transmit pressure to the inside of the percentage meter by lifting up, thereby obtaining the curvature difference data.

[0017] Before measurement, the crankshaft needs to be driven to rotate around the central axis. At this time, the first motor can be turned on, and the output power of the first motor drives the gear and the gear ring to engage with each other, so that the rotating ring drives the clamped crankshaft to rotate.

[0018] The present invention provides a bending detection device for crankshaft production, which has the following beneficial effects: 1. The present invention can effectively improve the detection and fixing effect of the device on crankshafts of different sizes, increase stability, and ensure the accuracy of curvature detection through the coordinated use of components such as a screw, an adjustment block, a gear ring, a rotating ring, and a gear.

[0019] 2. The present invention uses the sensor wheel, the sliding block, the travel groove and other components in coordination, and can simultaneously detect multiple data of the crankshaft during the detection process, effectively reducing the detection steps and improving the overall processing efficiency.

[0020] 3. The present invention can realize the effect of automatically driving the crankshaft to rotate through the coordinated use of the second motor, the screw rod, the adjustment block, the connecting block and other components, can replace manual operation, reduce detection errors and improve comprehensive detection stability.

Through such a design, the overall displacement distance range of the locking block 17 can be controlled.

[0026] Please refer to the attached Figure 6 A second motor 9 is fixedly connected to one side of the rotating ring 7, a screw 10 is fixedly connected to the output end of the second motor 9, an adjusting block 11 is threadedly connected to the outer wall of the screw 10, a connecting block 12 is rotatably connected to one side of the adjusting block 11, a middle ring 16 is fixedly connected to one side of the connecting block 12, and a plurality of supporting rods 15 are rotatably connected to the middle side of the middle ring 16, an adjusting component is arranged at the bottom of the positioning plate 3, and a detecting component is arranged at the top of the workbench 1.

[0027] The output of the second motor 9 drives the screw 10 to rotate, thereby driving the adjustment block 11 to gradually pull the connection position of the middle block through the threaded connection. The moving plate 14 is slidably connected to the inner wall of the support rod 15. During the movement of the middle block, the distance between the support rod 15 and the extension rod 13 is extended, thereby changing multiple moving plates 14 so that the locking block 17 gradually contacts with both sides of the crankshaft, thereby completing the fixation.

[0028] Before measurement, the crankshaft needs to be driven to rotate around the central axis. At this time, the first motor 5 can be turned on, and the gear 6 and the gear ring 8 are meshed and connected. The first motor 5 outputs power to drive the gear 6 and the gear ring 8 to mesh and connect, so that the rotating ring 7 drives the clamped crankshaft to rotate.

[0029] Please see attached Figure 7 -Attached Figure 8 The adjustment component includes a docking plate 23, which is fixedly connected to the bottom of the positioning plate 3. A plurality of assembly blocks 25 are fixedly connected to the middle side of the top of the workbench 1, and a track column 22 is fixedly connected to the inner wall of the assembly block 25.

[0033] Open the hand-tightening bolt 29, select the crankshaft detection position to be positioned by adjusting the position of the sliding block 27, and allow the sensor wheel 31 to fully contact the crankshaft position to be detected. When the curvature changes, pressure will be transmitted to the inside of the percentage meter by lifting up, thereby obtaining the curvature difference data.

[0034] Please see attached Figure 1 -Attached Figure 3 The hand-tightening bolts 29 pass through the through groove 28 and are threadedly connected to the top two sides of the sliding block 27. Through such a design, the accuracy of positioning and the stability of the percentage meter body 30 during the detection process can be improved. An inductive displacement sensor is installed inside the sensor wheel 31. The inductive displacement sensor is arranged inside the crankshaft to perform circumference statistics on the measured crankshaft end, thereby realizing the integrated effect of multi-data detection.
