As a specific embodiment of the present invention, a magnetic sheet is embedded in the bottom end of the non-slip mat 37, the rubber head 36 is in a cavity structure, the cavity of the rubber head 36 is communicated with the cavity of the telescopic rod 32, a magnetic block is embedded in the contact portion of the rubber head 36 and the bottom end of the non-slip mat 37, and the magnetic sheet and the magnetic block have opposite magnetism; when the gear aligning device works, if the rubber head 36 is too hard, the gear to be detected may be driven to rotate in the process that the rubber head 36 is withdrawn from the tooth groove downwards, so that the accuracy of gear aligning is influenced; by arranging the rubber head 36 into a cavity structure, the rubber head 36 is softened in the process of controlling the air release of the telescopic rod 32 by the second electromagnetic valve, so that the influence degree of the rubber head 36 on the gear in the process of exiting is reduced to the minimum; meanwhile, after the rubber head 36 enters the adjacent tooth grooves, the anti-slip pad 37 is opened under the action of the repulsive force of the magnetic blocks, so that the rotation of the gear is further limited by the anti-slip pad 37, and the gear can be correctly meshed.
When the gear meshing inspection device works, only one gear can be inspected at a time through the existing gear meshing inspection, the problem of batch gear detection is not solved, the gears need to be assembled and disassembled after each inspection, long detection time is needed for large batches of automobile gears, meanwhile, burden is brought to workers, and the gear meshing inspection device solves the problem; the invention is fixed on the workbench during inspection, so as to ensure the invention
The utility model can not be overturned when in work; then stringing the gear to be detected on the surface of the connecting rod 22 to ensure that the detected gear is concentric with the connecting rod 22; then the standard gear is arranged on the screw 14, and the standard gear is rotationally arranged on the bracket 12 by using the nut 15; then setting parameters of the detection gear and the standard gear on the controller, so that the invention can automatically check according to the setting; during inspection, the first motor 8 drives the screw rod 9 to rotate, so that the sliding plate 10 moves along the length direction of the screw rod 9; the sliding plate 10 moves to change the position of the standard gear on the bracket 12, and meanwhile, the push rod motor 3 drives the sliding block 5 to move up and down to change the standard position, so that the standard gear is meshed with the gear to be detected under the cooperation of the driving motor and the push rod motor 3; after the two are meshed, the second motor 13 drives the screw 14 to rotate, so that the standard gear rotates, and the gear to be detected synchronously rotates; if the gear to be detected is a non-standard gear, the standard gear is extruded downwards, so that the return spring 4 is pressed to generate compression; the slide plate 10 is moved downwards during the standard gear is pressed downwards, so that the transverse plate 16 on the side wall of the slide plate 10 is moved downwards; the laser distance measuring sensor 19 measures the distance between the transverse plate 16 and the transverse plate, so that the change value of the center distance between the gear to be detected and the standard gear is measured, and a result of whether the gear to be detected meets the standard is obtained; after the detection of the gear to be detected on the single connecting rod 22 is finished, the rotating disc 20 is rotated to rotate the gear which is not detected to the lowest point position of the rotating disc 20, so that the next continuous detection is facilitated; according to the invention, a large number of gears are connected in series, and the first motor 8 is utilized to drive the standard gear and each gear to be detected to continuously detect, so that the detection efficiency is improved by multiple times, and a large amount of loading and unloading time is saved, thereby improving the detection efficiency of the gears.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention.
