[0039] like Figures 1 to 11As shown, a seat component riveting detection equipment comprises a turntable 2 and a rotary drive mechanism 10. The turntable 2 is provided with a plurality of positioning fixtures 3 for placing adjusting components 7. The turntable 2 is provided with loading and unloading stations, a riveting station and a torque detection station in the circumferential direction. The turntable 2 is connected to the rotary drive mechanism 10. The rotary drive mechanism 10 drives the turntable 2 to rotate and makes the positioning fixture 3 on the turntable 2 pass through the loading and unloading stations, the riveting station and the torque detection station in sequence. The riveting station is provided with a riveting device 5 for riveting the seat component. The torque detection station is provided with a torque detection device 6 for detecting whether the screw cap torque on the adjusting component 7 is qualified. The loading and unloading station is provided with a loading and unloading mechanism, and the adjusting component 7 is placed on the positioning fixture 3 or removed from the positioning fixture 3 by the loading and unloading mechanism.

[0040] When the present invention is in use, the adjusting component 7 is first grabbed by the loading and unloading mechanism to the positioning fixture 3 located on the loading and unloading station, and the adjusting component 7 is positioned by the positioning fixture 3; then the turntable 2 rotates, and the adjusting component 7 is rotated to the riveting station by the rotation of the turntable 2, and the screw 7-2 and the plastic nut 7-1 on the adjusting component 7 are riveted by the riveting equipment 5 on the riveting station; after the riveting is completed, the turntable 2 continues to rotate so that the adjusting component 7 reaches the torque detection station, and the rotational torque of the plastic nut 7-1 is detected by the torque detection device 6. If the rotational torque is greater than the set torque, the product is judged to be unqualified, otherwise, if the rotational torque is less than the set torque, the product is judged to be qualified; after completing the torque detection of the adjusting component 7, the turntable 2 continues to rotate to the loading and unloading station, and then the product (adjusting component 7) is unloaded by the loading and unloading mechanism.

[0041] When the present invention is used, the entire processing and testing process does not require manual participation, has a high degree of automation, saves time and effort, greatly reduces labor costs, and improves production efficiency. The present invention uses a torque detection device 6 to detect the rotational torque of the plastic nut 7-1 on the adjustment component 7, replacing the traditional manual detection method, avoiding human errors in the detection process, and improving the reliability of the detection result.

[0042] The positioning tool 3 includes a tool body 3-1, on which a positioning boss 3-2 and a positioning pin 3-3 are provided, and the positioning pin 3-3 matches with the positioning hole 7-3 on the adjusting component 7.

[0043] The loading and unloading mechanism includes a loading conveyor belt 8, a unloading conveyor belt 9, and a loading and unloading manipulator 4 for grabbing the adjusting component 7. The adjusting component 7 (product) to be processed and tested is placed on the loading conveyor belt 8. When loading, the loading and unloading manipulator 4 transfers the adjusting component 7 on the loading conveyor belt 8 to the positioning fixture 3 on the turntable 2; when unloading, the loading and unloading manipulator 4 transfers the adjusted component 7 after the test from the positioning fixture 3 to the unloading conveyor belt 9. Among them, the qualified products are placed near the left side of the unloading conveyor belt 9, and the unqualified products are placed near the right side of the unloading conveyor belt 9, which is convenient for the staff to distinguish between qualified and unqualified products.

[0044] The riveting device 5 includes a first support frame 5-1, on which a fixing seat 5-2 is arranged, on which a riveting mechanism 5-5 and a clamping mechanism are arranged, and the clamping mechanism is used to clamp the plastic nut 7-1 on the adjusting component 7; the clamping mechanism includes two clamping driving members 5-3 arranged opposite to each other, and a clamping block 5-4 is arranged on the clamping driving member 5-3. In this embodiment, the riveting mechanism 5-5 adopts a rotary riveting machine. When the adjusting component 7 is riveted, the plastic nut 7-1 is first clamped and fixed by the clamping mechanism, so that the plastic nut 7-1 remains fixed during the riveting process.

[0045] The torque detection device 6 includes a second support frame 6-1, a lifting plate 6-3, and a clamp 6-10. A fixed plate 6-2 is arranged on the second support frame 6-1. The lifting plate 6-3 is located below the fixed plate 6-2. A lifting drive device 6-4 is arranged on the fixed plate 6-2. The lifting drive device 6-4 is connected to the lifting plate 6-3 and drives the lifting plate 6-3 to move up and down; a motor 6-5 is arranged on the lifting plate 6-3, a rotating shaft 6-8 is connected to the motor 6-5, a torque sensor 6-9 is arranged on the rotating shaft 6-8, and the clamp 6-10 is connected to the torque sensor 6-9. When the torque detection device 6 detects the rotational torque of the plastic nut 7-1, the method is as follows: first, the lifting drive device 6-4 drives the clamping jaw 6-10 to descend to the height position where the plastic nut 7-1 is located, and the clamping jaw 6-10 grasps the plastic nut 7-1; then the motor 6-5 starts and drives the plastic nut 7-1 to rotate, and the torque of the plastic nut 7-1 during rotation is detected by the torque sensor 6-9; if the torque value is greater than the set torque, the product is judged to be unqualified; conversely, if the torque value is less than the set torque, the product is judged to be qualified; after the detection is completed, the clamping jaw 6-10 loosens the plastic nut 7-1, and then the lifting drive device 6-4 drives the clamping jaw 6-10 to rise to the initial position.

[0046] In this embodiment, the clamping jaws 6-10 are electric clamping jaws 6-10.

[0047] Among them, a guide rod 6-6 is arranged on the lifting plate 6-3, and a guide sleeve 6-7 is arranged on the fixed plate 6-2, and the guide rod 6-6 passes through the guide sleeve 6-7.

[0048] Furthermore, a locking cylinder 3-4 is provided on the tooling body 3-1, and a first oil chamber is provided in the locking cylinder 3-4, and the first oil chamber includes a main chamber 3-9 and a guide chamber 3-10 provided on both sides of the upper end of the main chamber 3-9, and a movable block 3-5 is slidably provided in the guide chamber 3-10; a sealing ring 3-8 is provided between the movable block 3-5 and the inner wall of the guide chamber 3-10; a fixing member 3-6 is provided in the locking cylinder 3-4, and the fixing member 3-6 is located between the guide chamber 3-10, a tension spring 3-7 is provided between the fixing member 3-6 and one end of the movable block 3-5, and a slope 3-11 is provided at the other end of the movable block 3-5.

[0049] The present invention also includes a driving oil cylinder 11, which includes a driving cylinder body 11-1, a piston 11-2 is arranged in the driving cylinder body 11-1, an oil chamber is formed between the piston 11-2 and the upper end of the driving cylinder body 11-1, a push rod 11-3 is connected to the lower end of the piston 11-2, and a roller 11-6 is arranged at the lower end of the push rod 11-3; the first oil chamber and the second oil chamber 11-4 are connected by a connecting pipe 13; the first oil chamber and the second oil chamber 11-4 are both filled with hydraulic oil;

[0050] A control ring 12 is provided on the frame 1, and a contour surface is provided at the upper end of the control ring 12, and the contour surface includes a high position area 12-1 and a low position area 12-2; a roller 11-6 at the lower end of the push rod 11-3 contacts the contour surface at the upper end of the control ring 12;

[0051] When the adjusting component 7 is placed on the positioning fixture 3, the locking cylinder 3-4 passes through the through hole 7-4 on the adjusting component 7; when the positioning fixture 3 rotates to the loading and unloading station, the roller 11-6 at the lower end of the push rod 11-3 is located in the low position area 12-2 on the contour surface, and the movable block 3-5 is in a retracted state. At this time, the two movable blocks 3-5 can pass through the through hole 7-4 on the adjusting component 7; when the positioning fixture 3 rotates to the riveting station and the torque detection station, the roller 11-6 at the lower end of the push rod 11-3 contacts the high position area 12-1 on the control ring 12, and the movable blocks 3-5 are in an extended state, and the inclined surfaces 3-11 on the two movable blocks 3-5 are in contact with the edges of the through hole 7-4 on the adjusting component 7; the movable blocks 3-5 apply downward pressure on the adjusting component 7 through the inclined surfaces 3-11.

[0052] Among them, when the movable block 3-5 is in a retracted state, the distance between the front ends of the two movable blocks 3-5 (that is, the end of the movable block 3-5 away from the tension spring 3-7) is smaller than the diameter of the through hole 7-4. At this time, the two movable blocks 3-5 can pass through the through hole 7-4 on the adjusting component 7.

[0053] The positioning fixture 3 uses the cooperation between the positioning pin 3-3 and the positioning hole 7-3 to realize the positioning of the adjusting component 7. However, this positioning method cannot provide downward pressure on the adjusting component 7, which easily leads to the bottom of the adjusting component 7 not being able to be in close contact with the positioning fixture 3, thereby causing the adjusting component 7 to fail to be accurately placed on the positioning fixture 3. In the present invention, a locking cylinder 3-4 is provided on the positioning fixture 3 to provide downward pressure for the adjusting component 7 through the locking cylinder 3-4. When the positioning fixture 3 rotates to the loading and unloading station, the roller 11-6 at the lower end of the push rod 11-3 is located in the low-position area 12-2 on the contour surface, and the movable block 3-5 is in a retracted state. At this time, the two movable blocks 3-5 can pass through the through hole 7-4 on the adjusting component 7. In this state, the adjusting component 7 can be conveniently placed on the positioning fixture 3 or removed from the positioning fixture 3; when the positioning fixture 3 rotates to the riveting station and the torque detection station, the roller 11-6 at the lower end of the push rod 11-3 contacts the high-position area 12-1 on the control ring 12. At this time, the movable block 3-5 is in an extended state, and the inclined surfaces 3-11 on the two movable blocks 3-5 are in contact with the edges of the through holes 7-4 on the adjusting component 7. When the adjusting component 7 is in close contact with the positioning fixture 3, the bottom of the adjusting component 7 is in close contact with the positioning fixture 3, thereby ensuring the accurate placement of the adjusting component 7 on the positioning fixture 3; when the positioning fixture 3 is rotated from the detection station to the loading and unloading station, the roller 11-6 at the lower end of the push rod 11-3 moves from the high position area 12-1 on the control ring 12 to the low position area 12-2 on the control ring 12, and the two movable blocks 3-5 on the locking cylinder 3-4 are also switched from the extended state to the retracted state. At this time, the locking cylinder 3-4 contacts and locks the adjusting component 7, so that the adjusting component 7 can be removed from the positioning fixture 3.

[0054] A method for using a seat component riveting detection device comprises the following specific steps:

[0055] Step 1: The positioning fixture 3 rotates to the loading and unloading station, and the loading and unloading robot 4 grabs the adjusting component 7 from the loading conveyor belt 8 and moves the adjusting component 7 to the positioning fixture 3.

[0056] Step 2: The positioning tool 3 is rotated to the riveting station, and the screw 7 - 2 on the adjusting component 7 and the plastic nut 7 - 1 are riveted together by the riveting equipment 5 .

[0057] Step three: The positioning tool 3 is rotated to the torque detection station, and the torque of the plastic nut 7-1 is detected by the torque detection device 6; wherein, when the torque detection device 6 detects the torque of the plastic nut 7-1, the specific method is as follows: first, the lifting drive device 6-4 drives the clamping jaw 6-10 to descend to the height position where the plastic nut 7-1 is located, and the clamping jaw 6-10 grasps the plastic nut 7-1; then the motor 6-5 starts and drives the plastic nut 7-1 to rotate, and the torque of the plastic nut 7-1 during rotation is detected by the torque sensor 6-9; if the torque value is greater than the set torque, the product is judged to be unqualified; conversely, if the torque value is less than the set torque, the product is judged to be qualified; after the detection is completed, the clamping jaw 6-10 loosens the plastic nut 7-1, and then the lifting drive device 6-4 drives the clamping jaw 6-10 to rise to the initial position.

[0058] Step 4: The positioning fixture 3 rotates to the loading and unloading station, and the loading and unloading manipulator 4 grabs the adjusted component 7 that has been inspected from the positioning fixture 3 and transfers the adjusted component 7 to the unloading conveyor belt 9.

[0059] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
