[0002] The adjusting body is a key component for adjusting the tooth clearance on the steering gear. Two O-rings need to be installed in its groove to ensure the sealing performance and the clearance adjustment accuracy. However, due to the differences in part sizes during the automatic installation process, and the soft and deformable material of the O-ring, there is a risk of missing the installation of the O-ring. The traditional detection method mainly relies on manual visual inspection, which not only has low production efficiency, but also has a large labor intensity, and is prone to missed inspection or misjudgment.

[0003] In the prior art, common detection methods include: a vision detection system that performs visual recognition on the adjusting body through a high-precision camera, but this system has a high cost and high requirements for ambient light, and is prone to failure in a complex environment; contact sensing detection, which senses the presence of the O-ring through a mechanical probe or a shrapnel, but due to the complex structure, the probe is easily damaged, the maintenance cost is high, and it is difficult to perform compatible detection on adjusting bodies of different specifications.

[0004] The existing detection schemes still have many deficiencies in terms of automation degree, stability and detection accuracy, and are difficult to meet the requirements of large-scale production lines. Therefore, there is an urgent need in the market for a device with high stability, high detection accuracy and capable of automatically separating unqualified parts to replace the traditional manual detection method.

Embodiment 1

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution: a device for automatically identifying and adjusting the missing installation of O-rings on a body, including a feeding component, a clamping component, and a detection component. The feeding component includes a pushing cylinder 1, a feeding plate 3, and a sliding plate 4. The telescopic end of the pushing cylinder 1 is connected with a pushing block 2. The feeding plate 3 is arranged at one end of the sliding plate 4, and the pushing block 2 corresponds to the feeding plate 3. The pushing cylinder 1 is used to push the adjustment body 5 to be inspected along the feeding plate 3 into the sliding plate 4. The sliding plate 4 serves as a bearing platform for the adjustment body 5 to be inspected and cooperates with the detection component to realize the detection of O-rings. The detection component is used to detect the installation condition of the O-ring on the adjustment body 5. The detection component includes an upper O-ring detection component 6 and a lower O-ring detection component 7, which are respectively arranged on one side of the sliding plate 4. The upper O-ring detection component 6 includes an upper O-ring detection spring piece 20, a spring 21, a rotating pin 25, a detection mounting plate 26, a nylon block 27, and a mounting bracket 28. The nylon block 27 and the detection mounting plate 26 are sequentially arranged on the mounting bracket 28. The upper O-ring detection spring piece 20 is connected with the detection mounting plate 26 through the rotating pin 25. The spring 21 is arranged between the side plate of the upper O-ring detection spring piece 20 and the detection mounting plate 26. The spring 21 provides pressure for the O-ring detection spring piece to keep it in contact with the surface of the adjustment body 5 to be inspected during the detection process. The lower O-ring detection component 7 includes a lower O-ring detection spring piece 23. The installation positions of the upper O-ring detection spring piece 20 and the lower O-ring detection spring piece 23 are different; the upper O-ring detection spring piece 20 and the lower O-ring detection spring piece 23 are respectively used to detect different O-rings on the adjustment body 5 to be inspected. The lower O-ring detection spring piece 23 adopts the same installation structure. When the O-ring is missing from the adjustment body 5 to be inspected, the upper O-ring detection spring piece 20 and the lower O-ring detection spring piece 23 respectively contact the adjustment body 5 to be inspected to form a closed circuit, and the electrical signal is fed back to the PLC control module. The clamping component is used to clamp the adjustment body 5 to be inspected and move it horizontally. The clamping component includes a jaw cylinder one 17, a jaw cylinder two 16, a horizontal movement cylinder 18, and a cylinder mounting plate 15. The telescopic end of the horizontal movement cylinder 18 is connected with the cylinder mounting plate 15. The jaw cylinder one 17 and the jaw cylinder two 16 are respectively fixed on the cylinder mounting plate 15. The clamping ends of the jaw cylinders contact the outer circle of the adjustment body 5 to be inspected to stabilize the position of the adjustment body 5 to be inspected.

[0021] The detection mounting plate 26 is fixed on the mounting bracket 28 by mounting screws 22. An adjusting screw 24 for adjusting the O-ring detection spring piece is provided on the detection mounting plate 26. By rotating the adjusting screw 24, the angle of the O-ring detection spring piece can be adjusted to facilitate the O-ring detection of the object to be inspected and adjusted 5.

[0022] It further includes a bottom plate 19. A support plate 14 is arranged above the bottom plate 19. The support plate 14 is slidably connected to the bottom plate 19 in the front-back direction. The lateral movement cylinder 18 is fixed on the support plate 14. The cylinder mounting plate 15 is slidably connected to the support plate 14. The support plate 14 is used to mount the clamping assembly. The sliding structure of the support plate 14 enables the lateral movement of the cylinder mounting plate 15. A front-back movement cylinder 29 is arranged on the bottom plate 19. The telescopic end of the front-back movement cylinder 29 is connected to the side surface of the support plate 14. By driving the front-back movement of the support plate 14 by the front-back movement cylinder 29, the cyclic operation of the clamping cylinder for forward clamping action and backward releasing action is realized.

[0023] The other end of the slide plate 4 is provided with a shunting assembly for automatically shunting unqualified parts and qualified parts. The shunting assembly includes a missing part collection box 11, a complete part collection box 12, a shunting cylinder 13, a shunting plate 9, a rotating shaft 10 and a blanking chute 8. The missing part collection box 11 and the complete part collection box 12 are respectively arranged on the bottom plate 19. The upper end of the blanking chute 8 corresponds to the slide plate 4, and the lower end of the blanking chute 8 corresponds to the complete part collection box 12. The shunting plate 9 is arranged on the side of the blanking chute 8 through the rotating shaft 10. The other end of the shunting cylinder 13 is arranged in a hinged structure. The output end of the shunting cylinder 13 is connected to the shunting plate 9 for driving the rotation of the shunting plate 9. By driving the rotation of the shunting plate 9 by the shunting cylinder 13, the object to be inspected and adjusted 5 is enabled to slide into the missing part collection box 11 and the complete part collection box 12 respectively. The shunting cylinder 13 is electrically connected to the PLC control module.

[0024] Detection operation principle: The to-be-inspected adjustment body 5 moves into place along the loading plate 3. Under the action of the pushing block 2 driven by the pushing cylinder 1, it is pushed onto the slide plate 4. The clamping jaw cylinder can move horizontally left and right under the action of the horizontal moving cylinder 18. When the clamping jaw cylinder holds the to-be-inspected adjustment body 5 and moves it to the right, the height of the upper O-ring detection elastic piece 20 of the upper O-ring detection assembly 6 is the same as the height of the first O-ring of the to-be-inspected adjustment body 5, which is used to detect whether the first O-ring seal is installed on the to-be-inspected adjustment body 5. The height of the lower O-ring detection elastic piece 23 of the lower O-ring detection assembly 7 is the same as the height of the second O-ring of the to-be-inspected adjustment body 5, which is used to detect whether the second O-ring is installed on the to-be-inspected adjustment body 5. When both detection assemblies detect that the O-rings are correctly installed, it is judged as a qualified part, and the to-be-inspected adjustment body 5 flows into the complete part collection box 12 along the blanking chute 8. When any one of the two detection devices detects that the O-ring is not installed, the shunting cylinder 13 acts. The shunting cylinder 13 pushes the shunting plate 9 forward to rotate along the rotating shaft 10. The shunting plate 9 rotates by a certain angle, and the to-be-inspected adjustment body 5 without the installed O-ring automatically slides into the missing-installation collection box 11, realizing automatic shunting.

[0025] Detection principle: The to-be-inspected adjustment body 5 is made of metal. When the adjustment body moves on the slide plate 4, it is always in contact. The spring 21 and the O-ring detection elastic piece are installed and fixed on the nylon block 27. Due to the nylon insulation, the O-ring detection elastic piece is not connected to the slide plate 4. The positive pole of the 5V power supply is connected to the O-ring detection elastic piece, and the negative pole of the 5V power supply is connected to the slide plate 4. The to-be-inspected adjustment body 5 is in contact with the slide plate 4. The O-ring detection elastic piece can rotate around the rotating pin 25. Under the action of the spring 21, the O-ring detection elastic piece always points downward. When a workpiece with the O-ring correctly installed passes by, due to the O-ring protruding from the metal surface, the protruding part of the O-ring blocks, and the O-ring detection elastic piece is not in contact with the to-be-inspected adjustment body 5, and the circuit is not connected. When the O-ring is not installed, the O-ring detection elastic piece directly contacts the surface of the to-be-inspected adjustment body 5, and the to-be-inspected adjustment body 5 is in contact with the slide plate 4, forming a closed circuit, thereby feeding back the loop voltage signal to the PLC control module. The PLC control module controls the action of the shunting cylinder 13 according to the electrical signal, thereby realizing shunting.

[0026] The clamping jaw cylinder two 16, the clamping jaw cylinder one 17 and the slide plate 4 cooperate to realize the workpiece transfer, detection, and blanking process as follows:

[0027] I. The to-be-inspected adjustment body 5 on the loading plate 3 enters the slide plate 4 under the action of the pushing block 2. The front and rear moving cylinder 29 pushes the bottom plate 19 to move forward as a whole. The clamping jaw cylinder acts, and the clamping jaws close to clamp the outer circular surface of the adjustment body 5, realizing initial fixation. At this time, the slide plate 4 bears and guides the adjustment body 5 to move along the detection path on the plane.

[0028] II. Lateral movement detection: The lateral movement cylinder 18 is activated, pushing the cylinder mounting plate 15 to drive the entire clamping assembly, including the clamped adjustment body 5, to move smoothly along the lateral path of the slide plate 4. During the movement, the two O-ring mounting positions of the adjustment body 5 sequentially pass through the positions of the upper O-ring detection spring piece 20 and the lower O-ring detection spring piece 23. If the O-ring is completely installed, the spring piece is pushed up, and no contact forms an open circuit. If the installation is missed, the spring piece contacts the metal surface, jointly forming a closed circuit with the slide plate 4, thereby generating a closed circuit signal.

[0029] III. Release and blanking after detection: After the detection is completed, the first jaw cylinder 17 and the second jaw cylinder 16 act. At this time, the adjustment body 5 on the lateral movement cylinder 18 and the second jaw cylinder 16 is on the blanking chute 8, and the jaws open outward to release the adjustment body 5. At the same time, the front and rear movement cylinder 29 drives the pallet 14 to retract as a whole. If it is judged as a qualified part, after loosening, the adjustment body 5 slides into the blanking chute 8 in an inclined direction and finally enters the complete part collection box 12. If an O-ring installation is detected to be missed: The PLC controls the shunt cylinder 13 to act, pushing the shunt plate 9 to rotate, so that the sliding path points to the missed installation collection box 11, realizing automatic shunting, and cycling in sequence.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Without departing from the spirit and scope of the present invention, the present invention has various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
