Technical Field

The present application relates to the technical field of chain thickness measurement, and in particular to a chain thickness detection device based on laser measurement.

Background technique

Chains can be divided into roller chains, toothed chains and other types according to their structures, among which roller chains are the most widely used. Roller chains consist of inner chain plates, outer chain plates, pins, sleeves and rollers. The inner chain plates and sleeves, the outer chain plates and pins are respectively connected by interference fit, which are called inner and outer chain links; the rollers and sleeves, and the sleeves and pins are clearance fits. When the inner and outer chain plates are relatively flexed, the sleeves can rotate freely around the pins. The rollers are movably mounted on the sleeves. When working, the rollers roll along the sprocket tooth profiles to reduce the wear of the gear teeth. At present, in most chain production processes, the chain inspection is carried out manually, that is, relying on the experience of the inspectors, judging whether the chain is qualified by appearance observation and feel. It is conceivable that a large number of inspectors are required, which not only has low production efficiency and high labor costs, but also relies on the experience of the inspectors. In particular, it is easy to miss the inspection during the inspection of the chain dead joints, and the quality of the chain inspection is difficult to be guaranteed. There are deficiencies that need to be improved.

The chain thickness detection device based on laser measurement of the present invention has the following working process:

In the initial state, hydraulic oil is provided in the hydraulic oil chamber 14, hydraulic oil is provided in the push liquid chamber 22, the fixed block 37 does not clamp the fixed wheel 34, the sliding wheel 73 does not contact the contact wheel 69, chains are wound on the two sprocket wheels 33, and the thrust rack 42 does not mesh with the meshing wheel 38.

Start the detection motor 47 to output power, thereby driving the second threaded shaft 48 to rotate, thereby driving the threaded push plate 49 to move, thereby discharging the hydraulic oil in the push chamber 22 into the lifting chamber 44, thereby driving the detection block 11 to move upward, so that the marking rod 75 is in a position to contact the chain, and rotating the torsion block 60, thereby driving the transmission belt 52 to rotate, thereby driving the slider 54 to move up and down, thereby driving the intermediate shaft 58 to move up and down, so that the cleaning belt 59 moves to the position of contacting the chain, thereby cleaning the chain;

At this time, the power motor 25 is started to output power, thereby driving the power shaft 29 to rotate, thereby driving the power wheel 30 to rotate, thereby driving the driven wheel 32 to rotate, thereby driving the fixed shaft 53 and the force measuring wheel 76 to rotate, thereby driving the chain wheel 33 to rotate, so that the chain is unwound and reeled. At this time, the laser measuring device 43 detects the chain. At this time, the detection motor 47 is started to output power, thereby driving the drive shaft 50 to rotate, thereby driving the upper side wheel 51 to rotate, thereby driving the intermediate wheel 18 to rotate through the transmission belt 52, thereby driving the intermediate shaft 58 to rotate, thereby driving the cleaning belt 59 to rotate, so as to clean the chain to avoid affecting the detection. When an abnormal thickness is detected, the power shaft 29 stops rotating, and the first threaded shaft 28 starts to rotate, thereby driving the threaded plate 26 to move, so that the hydraulic pressure in the hydraulic oil chamber 14 is The oil is discharged into the push plate cavity 17 and the thrust cavity 20, thereby driving the push plate 35 to move, thereby driving the push rod 36 to move, thereby driving the fixed block 37 to move, so that the fixed block 37 clamps the fixed wheel 34, so that the fixed wheel 34 cannot rotate, thereby making the fixed shaft 53 unable to rotate, and thus making the left chain wheel 33 unable to rotate. When the hydraulic oil enters the thrust cavity 20, it drives the thrust plate 39 to rotate, thereby driving the thrust rod 40 to move, thereby driving the pressure sensor 41 to move, thereby driving the thrust rack 42 to move, and the thrust rack 42 contacts the meshing wheel 38, thereby driving the meshing wheel 38 to rotate, thereby driving the force measuring wheel 76 to rotate, thereby driving the right chain wheel 33 to rotate, thereby pulling the chain, and the pressure sensor 41 can record the thrust size, thereby checking whether the chain meets the tension standard;

Since a winding rope 70 with one end connected to the upper end wall of the detection chamber 13 is wound around the rotating wheel 68, when the rotating wheel 68 moves downward, it will rotate under the action of the winding rope 70, thereby driving the torsion shaft 66 to rotate, thereby driving the contact wheel 69 to rotate. When it is detected that the thickness of the chain is too thin, the right electromagnet 72 is energized. When it is detected that the thickness of the chain is too thick, the left electromagnet 72 is energized, thereby driving the sliding wheel 73 to move, thereby causing the sliding wheel 73 to contact the contact wheel 69, thereby driving the sliding wheel 73 to rotate, thereby driving the rotating shaft 71 to rotate, thereby driving the marking rod 75 to rotate, so that one end of the marking rod 75 is marked at the chain detection position, thereby facilitating the observation of the chain thickness.
