[0018] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0019] As shown in Figures 1-3, a rocker arm shaft laser detection device includes a workbench 10, which is characterized in that: two clamping components and a detection component are arranged on the workbench 10, wherein the clamping components are located on both sides of the detection component, and the detection component is movably connected on the workbench 10, and the detection component includes an upper adjustment seat 16 and a lower adjustment seat 17, and the upper adjustment seat 16 and the lower adjustment seat 17 are hinged to each other, and the upper adjustment seat 16 and the lower adjustment seat 17 are both provided with a semicircle, and when the upper adjustment seat 16 and the lower adjustment seat 17 are closed, a complete circle is formed, a slide rail 21 is fixed on the workbench 10, and a slide seat 22 is fixed at the bottom of the lower adjustment seat 17, and the slide seat 22 slides on the slide rail 21, and a slider 19 that slides up and down is provided in the upper adjustment seat 16, and the slide A screw block 23 is installed in the block 19 through a spring, and an adjusting screw rod 18 is connected to the inner thread of the screw block 23. The adjusting screw rod 18 passes through the upper adjusting seat 16 to the outside. Two symmetrically arranged paint cavities 24 are also provided inside the slider 19. A laser sensor 20 is fixed to one end face of the slider 19. The wear of the rocker shaft is detected through the bottom of the slider 19. The detection component includes an auxiliary clamping base 15 and a main clamping base 11, wherein a three-jaw chuck 13 is rotatably connected in the main clamping base 11, and a motor 12 is provided on the side of the main clamping base 11 away from the auxiliary clamping base 15. The motor 12 and the three-jaw chuck 13 are installed together, and a laser lamp 14 is movably connected to the upper end face of the main clamping base 11, and the laser lamp 14 corresponds to the laser sensor 20.

[0020] A sliding cavity is provided on the side end face of the upper adjustment seat 16, and a slider 19 is located in the sliding cavity. The bottom of the slider 19 is arranged in an inverted tower shape, and two nozzles are provided at the bottom, and the nozzles are connected to the pigment cavity 24. There is also a partial protrusion at the bottom of the slider 19, and the two nozzles are distributed on both sides of the protrusion. The liquid filled in the pigment cavity 24 has different colors.

[0021] When in use, insert one end of the rocker shaft to be tested into the auxiliary clamping base 15, and the other end into the three-jaw chuck 13, fix the rocker shaft through the three-jaw chuck 13, and then rotate the upper adjustment seat 16 to make the upper adjustment seat 16 buckle on the lower adjustment seat 17, and rotate the adjusting screw rod 18 to make the screw block 23 drive the slider 19 to move through the spring until the slider 19 just abuts against the rocker shaft and the spring is in a compressed state. At this time, push the detection component to the vicinity of the three-jaw chuck 13, and then adjust the laser light 14 so that the light spot of the laser light 14 is irradiated in the middle of the laser sensor 20. At this time, the motor 12 can be started to rotate, and the rocker shaft can be driven to rotate through the three-jaw chuck 13. When the surface here is relatively smooth, the position of the slider 19 will not change, and the laser sensor 20 can always receive the light of the laser light 14. When the surface here is more worn, when the wear is When it rotates to the slider 19, the slider 19 will move downward due to the notch of the rocker shaft. The downward movement of the slider 19 will drive the laser sensor 20 to move downward synchronously. At this time, the light spot of the laser lamp 14 will be near the upper side of the laser sensor 20.
