[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-2A pinion grading device includes a pinion grading device body, which includes a welded lower frame 1. Multiple locking casters 10 are rotatably mounted on the bottom of the welded lower frame 1, allowing the entire device to move. A welded upper frame 8 is fixedly connected to the top of the welded lower frame 1. A PLC controller 3 is fixedly connected between the inner walls of both sides of the welded upper frame 8, supporting the PLC controller 3. A human-machine interface is provided on the front side of the PLC controller 3. A tooling 7 is fixedly connected to the front side of the welded lower frame 1, and a barcode scanner 6 is fixedly connected to the right front side of the welded lower frame 1. The barcode scanner 6 is used to scan barcodes on products.

[0020] Both sides of the tooling 7 are equipped with displacement sensors 701 fixedly installed on the top of the welding lower frame 1. The displacement sensors 701 are used to detect the displacement of the product. The detection principle is existing technology and will not be described in detail here. The bottom left side of the tooling 7 is equipped with an NG material box 4 fixedly installed on the welding lower frame 1. The NG material box 4 is used to place unqualified products.

[0021] The fixture 7 includes multiple input shafts 702. An upper weight 703 and a lower weight 704 are sleeved on the input shafts 702. The upper weight 703 and the lower weight 704 cooperate with each other. The lower weight 704 is fixedly sleeved on the corresponding input shaft 702, and the upper weight 703 is movably sleeved on the corresponding input shaft 702. A drive component 705 for driving it is installed on the upper weight 703.

[0022] A feeding mechanism 2 is fixedly installed on the rear side of the welding frame 8. An inclined feeding slide 201 is fixedly connected to the front side of the feeding mechanism 2. The front side of the feeding slide 201 extends through the welding frame 8 to its front side. A type detection sensor is fixedly installed on the welding frame 8 above the feeding slide 201. A start switch 9 is fixedly connected to the inner walls on both sides of the welding frame 8. A three-color alarm light 5 is fixedly installed on the top right side of the welding frame 8. The three-color alarm light 5, the type detection sensor, the start switch 9, the displacement sensor 701, and the barcode scanner 6 are all electrically connected to the PLC controller 3. The start switch 9 on the left side controls the type detection sensor through the PLC controller 3, and the start switch 9 on the right side controls the drive component 705 through the PLC controller 3. Through a series of structural settings, this utility model can perform secondary detection on the pinion and needle roller bearings during the pinion grading process, thereby effectively improving the detection accuracy and making up for the deficiencies in the accuracy of existing devices.

[0023] Working principle: When in use, the pinion gear and needle roller bearing are placed in the feeding mechanism 2 in sequence. The pinion gear and needle roller bearing slide down the inclined surface of the feeding slide 201 to the bottom of the type detection sensor. Then, the type detection sensor is turned on by the start switch 9 on the left and the PLC controller 3. The type detection sensor detects the type of the product inside the feeding slide 201 and determines whether the type is qualified. If it is not qualified, the PLC controller 3 controls the three-color alarm light 5 to light up red to remind the personnel. The personnel can then take the unqualified product out of the feeding slide 201 and put it into the NG material box 4.

[0024] Simultaneously, the qualified pinion and needle roller bearing are removed and fitted onto the corresponding input shaft 702. The barcodes on the pinion and needle roller bearing are scanned by the barcode scanner 6, and the scanned information is transmitted to the PLC controller 3. At this time, the pinion and needle roller bearing are supported by the corresponding lower weight 704. After fitting, pressing the start switch 9 on the right side controls the drive component 705 to start via the PLC controller 3. The drive component 705 drives the corresponding upper weight 703 to move down and press down on the pinion. Then, the input shaft 702 rotates, which drives the pinion to rotate through the lower weight 704, simulating the actual running state. During the rotation, the displacement sensor 701 detects the needle roller. The bearing displacement is assessed to determine the suitability of the needle roller bearing for the pinion drive. A suitable needle roller bearing model is recommended based on calculations. Simultaneously, the detected information is transmitted to the PLC controller 3. The PLC controller 3 analyzes the pass / fail status of the pinion and needle roller bearing. Upon completion of the inspection, the three-color alarm light 5 illuminates green, indicating the product can be removed. If any defects are detected during the inspection, the three-color alarm light 5 illuminates red to alert personnel. The defective product is then removed and placed in the NG (Not Qualified) bin 4. This secondary inspection of the pinion and needle roller bearing, using a combination of type detection sensors and displacement sensors 701, effectively improves the accuracy of the inspection.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
