Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 6This utility model provides an inspection machine for fastener processing of automotive steering systems, including a housing 1 and a support platform 4 connected inside the housing 1. The two ends of the support platform 4 are connected to a feeding mechanism 2 and a discharging mechanism 3. The support platform 4 is connected to a transfer mechanism for bushing transfer. The transfer mechanism includes a fixed base 13, a horizontal rail 16, a first motor 19, a vertical rail 20, a second motor 22, a moving plate 14, and multiple clamping cylinders 15. The fixed base 13 is connected to the top of the support platform 4, and the horizontal rail 16 is connected to the fixed base 13. The second motor 22 drives the vertical rail 20 to reciprocate along the length of the horizontal rail 16, and the first motor 19 drives the moving plate 14 to reciprocate along the height of the vertical rail 20. Multiple clamping cylinders 15 are equidistantly connected to the sides of the moving plate 14. An inspection mechanism for inspecting bushings is connected inside the housing 1.

[0022] The feeding mechanism 2 and discharging mechanism 3 include a support frame 8, a conveyor belt 9, a drive motor 10, and two rotating rollers. The support frame 8 is connected to the support platform 4, and the rotating rollers are rotatably connected to the support frame 8. The two rotating rollers are connected via the conveyor belt 9. The drive motor 10 is connected to the support frame 8, and the power output end of the drive motor 10 is connected to the rotating rollers. When a product is placed on the feeding mechanism 2, it is immediately conveyed into the machine housing 1. The transfer mechanism then transfers and conveys the product, allowing it to pass through stations one through six for inspection and processing. Figure 5 The middle arrow indicates the product conveying direction and marks the corresponding workstation. After all products have been fully inspected, the last clamping cylinder 15 clamps the product and discharges it through the discharge mechanism 3.

[0023] The support frame 8 is connected to a first-stage pusher cylinder 5 and a buffer hopper 6. The buffer hopper 6 is positioned opposite to the first-stage pusher cylinder 5, with its outlet facing the discharge channel 11 connected to the top of the support platform 4. A second-stage pusher cylinder 7 is connected to the end of the discharge channel 11. When a product fails inspection, the first-stage pusher cylinder 5 pushes the product into the buffer hopper 6, where it falls from the bottom to the discharge channel 11. The second-stage pusher cylinder 7 then pushes the product into a collection box for subsequent centralized processing. Qualified products continue to move along the length of the conveyor belt 9, thus eliminating and screening out unqualified products and preventing confusion.

[0024] The transfer mechanism also includes a sliding block 17, a sliding block 21, and two lead screws. A motor 22 is connected to the end of the transverse track 16, and the power output end of the motor 22 is connected to the lead screw. The lead screw is threadedly connected to the sliding block 17. The sliding block 17 is slidably connected to the transverse track 16 and is connected to the vertical track 20. A motor 19 is connected to the top of the vertical track 20, and the power output end of the motor 19 is connected to the lead screw. The lead screw is threadedly connected to the sliding block 21. The sliding block 21 is slidably connected to the vertical track 20 and is connected to the moving plate 14.

[0025] Motor 22 drives the lead screw to rotate, which in turn drives the sliding block 17 to move back and forth along the length of the transverse track 16. Simultaneously, it drives the vertical track 20, the moving plate 14, and the seven clamping cylinders 15 to move back and forth laterally. Meanwhile, motor 19 drives the lead screw to rotate, which drives the sliding block 21 to move back and forth along the height of the vertical track 20. This enables the moving plate 14 and the seven clamping cylinders 15 to perform lifting and lowering actions, facilitating the transfer and handling of products.

[0026] The clamping cylinders 15 located at the beginning and end clamp the inner ring of the product, enabling product transfer. For example... Figure 4 The middle arrow indicates the direction of product movement, while the third clamping cylinder 15 on the right is a rotary clamping cylinder that flips the product over to facilitate subsequent inspection of the bottom surface.

[0027] The testing mechanism includes multiple camera mounts 12, multiple high-definition cameras 23, testing platform six 24, motor five 26, testing platform five 27, testing platform four 28, testing platform three 29, motor four 30, cylinder 31, motor three 32, testing platform two 33, pneumatic measuring instrument 34, testing platform one 35, testing platform one 35, testing platform two 33, testing platform three 29, testing platform four 28, testing platform five 27, and testing platform six 24, arranged from right to left. Cylinder 31 is connected to... The bottom of the support platform 4 is connected to the power output end of the cylinder 31, which is connected to the power output end of the motor 32. The power output end of the motor 32 is connected to the test platform 2 33, which corresponds to the pneumatic measuring instrument 34. The pneumatic measuring instrument 34 is connected to the top of the support platform 4. The motor 4 30 is connected to the support platform 4, and the power output end of the motor 4 30 is connected to the test platform 3 29. The motor 5 26 is connected to the support platform 4, and the power output end of the motor 5 26 is connected to the test platform 5 27.

[0028] The HD camera 23 has five settings, namely: Figure 5In steps a, b, c, d, and e, step a photographs the two stepped surfaces 001 of the product. The product is then transferred to the second workstation. Cylinder 31 drives motor 32 and the inspection table 33 to move forward, bringing the product close to the pneumatic measuring instrument 34. Motor 32 drives the product to rotate 360°, measuring the product's outer diameter and roundness. The pneumatic measuring instrument 34 is existing technology, capable of converting changes in workpiece dimensions into changes in compressed air flow or pressure, which are then indicated by an indicator device, thus measuring the workpiece's dimensional error. The pneumatic measuring instrument 34 generally consists of two parts: the instrument body (float-type pneumatic measuring instrument, pointer-type pneumatic measuring instrument, or electronic pneumatic measuring instrument) and the measuring device (also called a pneumatic measuring head). The same pneumatic measuring instrument body, equipped with different pneumatic measuring heads, can measure various parameters of the workpiece, such as length, thickness, groove width, inner hole diameter, outer diameter, center distance between two holes, straightness of the axis, roundness, coaxiality, perpendicularity, and flatness. Then, the product is transferred to the third station, where b takes photos of the product's inner side. Simultaneously, motor 430 drives the product to rotate 360° for multi-position photography. The product is then transferred to the fourth station, c, where it is photographed to check the product's inner diameter. Between the fourth and fifth stations, a rotary clamping cylinder flips the product 180°, placing it on inspection table 527. D then photographs the product, while motor 526 drives inspection table 527 to rotate, synchronously rotating the product for easy inspection of its outer diameter, appearance, and height. Further, the product is transferred to the sixth station, e, where e photographs the product with its bottom facing upwards for bottom appearance inspection. Finally, all inspection information is fed back to the PLC controller for centralized processing to determine if the product has defects, which are then screened by the subsequent pushing cylinder 5.

[0029] The camera mount 12 is connected to the top of the support platform 4, and the high-definition camera 23 is connected to the camera mount 12. The high-definition cameras 23 located on the first inspection platform 35, the fourth inspection platform 28, and the sixth inspection platform 24 are vertically distributed, the high-definition cameras 23 located on the third inspection platform 29 are inclined, and the high-definition cameras 23 located on the fifth inspection platform 27 are horizontally distributed.

[0030] A PLC controller is connected inside the housing 1. The PLC controller is electrically connected to the feeding mechanism 2, the discharging mechanism 3, the transfer mechanism, and the detection mechanism.
