In an automobile production line, the tightening of bolts, nuts, screws, studs, etc. accounts for a considerable part of the workload of the entire manufacturing process. Traditionally, it is manual tightening, and there have also been some semi-automatic tightening scenarios, but still cannot meet the requirements of high-efficiency unmanned operation in current intelligent manufacturing. Therefore, it is necessary to design an intelligent tightening device and system.

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Height measurement verification device See also Figure 1 and Figure 2 The height measurement and verification device 840 includes a displacement mounting plate 841 , a displacement driver 842 , a traction block 843 , a sliding module 844 , a detection mounting seat 845 and a floating height meter 846 .

[0019] Arrangement relationship: The chute block of the displacement driver 842 and the sliding module 844 is fixed to the side surface of the displacement mounting plate 841. One side surface of the traction block 843 is fixed to the outer side surface of the upper section of the slide rail of the sliding module 844, and the end of the driving rod of the displacement driver 842 is connected to the traction block 843. The detection mounting seat 845 in a "C" shape is mounted to the outer side surface of the lower section of the slide rail of the sliding module 844, and the floating height gauge 846 is mounted on the detection mounting seat 845 and moves up and down synchronously.

[0020] Furthermore, a height measurement contact bottom plate 847 is also provided at the bottom of the detection mounting seat 845. The hardness of the height measurement contact bottom plate 847 is lower than that of the detection mounting seat 845, preventing the bottom surface of the detection mounting seat 845 from making hard contact with the workpiece to be measured during height measurement, thereby reducing the probability of damage.

[0021] Furthermore, two lifting limit components 848 are also provided on the side of the displacement mounting plate 841. The limiting ends of the two lifting limit components 848 face the upper and lower surfaces of the traction block 843, thereby limiting the overall lifting stroke of the slider of the sliding module 844, the detection mounting seat 845, and the floating height gauge 846.

[0022] Among them, the floating height gauge 846 includes a height gauge body 8461, a height measurement floating rod 8462, and a detection floating head 8463. The height measurement floating rod 8462 is floatingly arranged at the lower part of the height gauge body 8461 and partially retracts into the height gauge body 8461 during height measurement. The detection floating head 8463 is replaceably arranged at the lowermost end of the height measurement floating rod 8462 and is used to abut against the workpiece to be measured.

[0023] Both the upper and lower end extension support parts of the detection mounting seat 845 are provided with holes. The upper hole is used to support and mount the floating height gauge 846, and the lower hole is used for the through-hole guidance of the detection floating head 8463.

[0024] Furthermore, a floating head guide cylinder 8464 is also provided in the hole opened at the lower end of the detection mounting seat 845 for guiding the detection floating head 8463.

[0025] The use of the material of the floating head guide cylinder 8464 ensures that the friction force during the up and down movement of the detection floating head 8463 is minimized, that is, the floating head guide cylinder 8464 plays a role in guiding and reducing friction. The material of the guide cylinder can be composed of bronze, peek plastic, composite materials, etc.

[0026] A limit protection block 849 is also provided in the middle of the detection mounting seat 845 for limiting the stroke of the detection floating head 8463.

[0028] Height measurement method: the workpiece to be measured reaches the height measurement station through the material tray seat, the height measurement verification device 840 is driven by the measured space transfer mechanism to be transferred to the top of the workpiece to be measured, the displacement driver 842 drives the floating altimeter 846 to move to the height measurement starting point, the bottom surface of the detection floating head 8463 abuts against the upper surface of the workpiece to be measured, and then driven to unlock, the height measuring floating rod 8462 and the detection floating head 8463 of the floating altimeter 846 freely fall under gravity until they are stopped by the workpiece to be measured, thereby the floating altimeter 846 calculates the moving distance of the height measuring floating rod 8462 and the detection floating head 8463, which is the height of the workpiece to be measured.

[0029] Intelligent tightening system See also Figure 5 The intelligent tightening system includes a first feeding device 100, a conveying device 200, a feeding visual judgment mechanism 300, a tightening part transfer device 400, a tightening device 500, a second feeding and transmission device 600, a pressing plate mechanism 700 and a height measurement verification device 800.

[0030] A loading visual judgment mechanism 300 is arranged corresponding to the picking position of the handling device 200, and the fastening part transfer device 400 is set between the tightening station of the second feeding and transmission device 600 and the handling device 200. The tightening execution part of the tightening device 500 with a torque detection function moves in a reciprocating space that can be raised and lowered between the fastening part transfer device 400 and the tightening station of the second feeding and transmission device 600; the height measurement verification equipment 800 is set at the tightening state detection station of the second feeding and transmission device 600, and is used to detect whether the height of the fastening part after tightening is qualified.

[0031] The pressing plate mechanism 700 is arranged above the tightening station of the second feeding and conveying device 600 in a liftable manner, and releases or tightens the tightened parts on the tightening station by lifting.

[0032] The second feeding and transmission device 600 adopts a linear rail mechanism, and the aforementioned material tray seat is movably supported on the linear rail. The linear rail is provided with a material receiving station, a tightening station, a tightening state detection station and a material unloading station. At the tightening state detection station, the height measurement verification device 800 is started to perform height detection on the workpiece to be tested to determine whether the tightening state is qualified.
