Description

Technical Field

[0001] The utility model relates to the field of chain thickness detection, in particular to a chain thickness detection device based on laser measurement. Background Art

[0002] 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 sleeve can rotate freely around the pin. The rollers are movably mounted on the sleeves. When working, the rollers roll along the sprocket tooth profile, which can 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.

[0004] In the process of realizing the utility model, the inventor found that there are at least the following problems in the technology: after the chain to be tested is put on the sprocket, one of the sprockets is pushed by the tensioning cylinder to achieve tensioning, but after the tensioning cylinder is pushed, a certain tensioning force cannot be sensed, which easily causes the chain to be torn and damaged. Therefore, a chain thickness detection device based on laser measurement is now proposed. Utility Model Content

[0029] Reference Figure 1 and Figure 2 A driving assembly is provided on the base 1, and the driving assembly includes a driving motor 12. The driving motor 12 is fixedly installed on one side of the base 1. The output shaft of the driving motor 12 is fixedly connected to a first rotating rod 13. A second rotating rod 15 is rotatably connected to the base 1. Both the first rotating rod 13 and the second rotating rod 15 are fixedly connected to a synchronous gear 14. The two synchronous gears 14 are meshed with each other. One end of the second rotating rod 15 is fixedly connected to a fixed-point sprocket 16.

[0030] Reference Figure 2 and Figure 3 Two sensing seats 4 are symmetrically fixedly installed on the extension seat 3, and the two sensing seats 4 are each provided with a sensing mechanism, which includes four first sliders 17, and the four first sliders 17 slide in the two sensing seats 4 respectively, and one side of the four first sliders 17 is fixedly connected with a return spring 18, and pressure sensors 19 are fixedly provided on the inner walls of both sides of the two sensing seats 4, and the four first sliders 17 are each hinged with a connecting rod 20, and one end of the four connecting rods 20 is hinged with a second slider 21, and the four second sliders 21 are respectively slidably connected to two top plates 22, and the two top plates 22 are each provided with a contact wheel 23, and the two sensing seats 4 are fixedly connected with two auxiliary telescopic rods 24, and one end of the four auxiliary telescopic rods 24 is respectively fixedly connected to the two top plates 22.

[0031] The implementation principle of the utility model is as follows: the chain to be detected is put on the moving sprocket 7 and the fixed-point sprocket 16, and the controller 8 is used to drive the first electric push rod 5 to drive the moving block 6 to move, and the moving block 6 drives the moving wheel 7 to move, so that the movement can be adjusted according to the length of the chain to be detected. When the upper and lower parts of the chain to be detected squeeze the two contact wheels 23, the two top plates 22 can move downward, and the two top plates 22 drive the four connecting rods 20 with the intersection as the center through the four second sliders 21.

Since there are two synchronous gears 14 meshing between the first rotating rod 13 and the second rotating rod 15, the second rotating rod 15 drives the fixed-point sprocket 16 to rotate. Since the fixed-point sprocket 16 and the mobile sprocket 7 are both meshed with the chain to be detected, the chain to be detected is driven, and the ink on the marking brush 11 will be smeared on the chain. After the chain is driven one circle, the chain can be removed and the mark on the chain can be observed. The place without the mark is a dead knot.
