[0002] The crankshaft is a core component of the engine, and its machining accuracy directly affects the engine performance. In the crankshaft machining process, high-precision punch presses are used for punching, trimming, and other processes on the crankshaft blank.

[0003] Because high-speed moving parts of punch presses (such as slides and dies) pose significant safety hazards, traditional protective devices mostly use mechanical fences or fixed protective covers. Although these can prevent personnel from contacting dangerous areas, they lack flexibility and cannot monitor the safety of personnel in the operating area in real time.

[0004] While existing photoelectric protection devices can achieve non-contact protection, traditional infrared beam-guided devices have a large beam spacing, making it difficult to detect intrusions into small limbs. Furthermore, the worktable size and mold height vary greatly among different models of punch presses, making it difficult for infrared beam-guided protection devices to quickly adapt to molds of different heights and lengths, resulting in poor practicality.

[0005] Therefore, it is necessary to provide a photoelectric protection device for high-precision crankshaft punch presses to solve the above-mentioned technical problems. Utility Model Content

A photoelectric protection device for a high-precision crankshaft punch press includes: a worktable 1 and a movable component 3;

[0028] Two sets of movable parts 3 are respectively fixedly installed on the front and rear sides of the top of the workbench 1. The movable parts 3 include mounting blocks 31, lifting parts 32, connecting blocks 33, sliding grooves 34 and threaded rods 35. The two mounting blocks 31 are respectively fixedly installed on the left and right sides of the surface of the workbench 1. The lifting parts 32 are fixedly installed on the top inside the mounting blocks 31. The connecting blocks 33 are fixedly installed on the top of the output shaft of the lifting parts 32. The sliding grooves 34 are opened in the middle of one side of the connecting blocks 33. The threaded rods 35 are rotatably installed inside the sliding grooves 34.

[0029] The monitoring component 4 is threadedly engaged with the outer surface of the threaded rod 35. The monitoring component 4 includes a slider 41, a mounting base 42, a photoelectric monitoring system 43, and a threaded hole 44. The slider 41 is threadedly engaged with the outer surface of the threaded rod 35. The mounting base 42 is fixedly installed on one side of the slider 41. The photoelectric monitoring system 43 is disposed on one side of the mounting base 42. The threaded hole 44 is opened on one side of the outer surface of the slider 41.

[0032] The lifting component 32 is a hydraulic cylinder structure.

[0033] A central control module is installed on one side of the surface of the stamping equipment 2.

[0034] The detection components 4 on the surfaces of the two sets of moving parts 3 correspond to each other, one being the transmitter and the other the receiver, and they move synchronously.

[0036] The working principle of the photoelectric protection device for high-precision crankshaft punching machine provided by this utility model is as follows:

[0037] During operation, the output shaft of the lifting component 32 can be moved up and down to adjust the height of the mounting block 31 and the monitoring component 4. The alternating forward and reverse rotation of the threaded rod 35 can adjust the position of the detection component 4 in the slide groove 34, adapting to different punch press worktable widths and crankshafts of different widths.

[0038] One set of monitoring components 4 serves as the transmitter, integrating 128 sets of infrared emitting tubes arranged in a matrix with a beam spacing of 5mm, forming a high-density infrared light curtain that can detect obstacles with a diameter as small as 5mm.

[0039] The other monitoring component 4 is the receiving end, which is equipped with 128 infrared receiving tubes, and has a built-in signal amplification module and anti-interference filtering circuit, which can effectively filter stray light and electromagnetic interference generated by the vibration of the punch press.

[0040] The transmitter and receiver work synchronously. The control module uses an industrial-grade PLC. When it receives a signal from the receiver and detects that the light curtain is blocked, it outputs a stop signal to the punch press control system and triggers the buzzer and warning light at the same time.
