[0026] Reference Figures 1 to 3 , a metal rod bending angle measuring device, comprising a bottom plate 1, a positioning member 3 and a detecting member 6. The positioning member 3 and the detecting member 6 both penetrate through the bottom plate 1, and the positioning member 3 corresponds to the detecting member 6 in position;

[0027] A through hole 2 is provided on the bottom plate 1, and the positioning member 3 penetrates through the through hole 2 to avoid interference;

[0028] The positioning member 3 includes a cylinder 4 and a pressing plate 5. The push rod of the cylinder 4 penetrates through the through hole 2, and the pressing plate 5 is movably connected to the cylinder 4 through the push rod of the cylinder 4, and is used to drive the pressing plate 5 to press the metal rod for positioning. The pressing plate 5 corresponds to the detecting member 6 in position, and is used to facilitate the detecting member 6 to detect the metal rod after the pressing plate 5 positions the metal rod;

[0029] The detection component 6 includes a power component 7, an adsorption component 8, a moving component 9, and a detection component 12; the adsorption component 8 is movably connected to the bottom plate 1 through the rotating shaft of the power component 7, and is used to drive the adsorption component 8, the moving component 9, and the detection component 12 to rotate, so as to detect the bending angle of the metal rod. The rotating shaft of the power component 7 penetrates through the bottom plate 1, and the moving component 9 penetrates through the adsorption component 8 to ensure that the moving component 9 can have relative movement with the adsorption component 8. The moving component 9 is movably connected to the adsorption component 8 through a tensioning component 10, and is used to push the detection component 12 on the mounting component 11 to keep contacting the metal rod when the adsorption component 8 no longer generates an adsorption force on the connection disk. Both the positioning component 3 and the detection component 6 are connected to an external control system, which is used to control the operation and stop of several components and transmit signals.

[0030] The detection component 12 is connected to the moving component 9 through the mounting component 11. A connection disk is arranged on the moving component 9, and the connection disk is movably connected to the adsorption component 8 through the tensioning component 10, and is used to push the detection component 12 on the mounting component 11 to keep contacting the metal rod when the adsorption component 8 no longer generates an adsorption force on the connection disk.

[0031] The detection component 12 is connected to the end of the moving component 9 through the mounting component 11. The connection disk is located at one end of the moving component 9 close to the detection component 12. The tensioning component 10 is an elastic element, and is used to push the detection component 12 on the mounting component 11 to keep contacting the metal rod when the adsorption component 8 no longer generates an adsorption force on the connection disk.

[0032] The detection component 12 is specifically a pressure sensor and is used to contact the metal rod. When the adsorption component 8 no longer has magnetic suction force, the pushing force of the tensioning component 10 on the connection disk is certain. At this time, the distance between the side of the metal rod and the detection component 12 is different, so that the pressure between the side of the metal rod and the detection component 12 is different. Thus, by detecting the pressure change signal transmitted by the detection component 12, the shape change of the metal rod can be finally obtained. The connection disk is separated from the adsorption component 8, and the tensioning component 10 is specifically a spring.

[0033] The detection component 12 is fixedly connected to the mounting component 11, and the tensioning component 10 is only connected to the connection disk of the moving component 9, so as to avoid interference between the tensioning component 10 and the main body part of the moving component 9.

[0034] The detection component 12 corresponds to the positioning component 3 in position, and the tensioning component 10 is located outside the main body part of the moving component 9.

[0035] The adsorption component 8 is a magnetic element and is used to generate a magnetic suction force on the connection disk of the moving component 9 after being energized. The connection disk of the moving component 9 is made of a metal material, and the main body part of the moving component 9 is made of a rigid material.

[0036] The adsorbing member 8 is specifically an electromagnet, which is used to conveniently control the generation and disappearance of the magnetic attraction force of the adsorbing member 8. The connecting plate is made of iron, and the main body part of the moving member 9 is made of aluminum metal. The main body part of the moving member 9 is cylindrical.

[0037] There are multiple positioning members 3, which are used to cooperate with each other to position the metal rod. The pressing plate 5, the adsorbing member 8, the moving member 9, and the detecting member 12 are all located on the same side of the bottom plate 1. The power member 7 is a motor, which is used to provide a rotational force. The air cylinder 4 is specifically a rotary pressing air cylinder, which is used to drive the pressing plate 5 to rotate while driving the pressing plate 5 to approach the metal rod.

[0038] The pressing plate 5 is a flat plate, which is used to directly press the metal rod. The pressing plate 5 is specifically composed of a rigid material. The power member 7 is specifically a stepping motor, which is used to drive the adsorbing member 8 to rotate at a constant speed.

[0039] The working principle of the present utility model is as follows: Before starting to use a metal rod bending angle measuring device, the metal rod bending angle measuring device is installed at the detection position. At this time, the connecting part at the edge of the bottom plate 1 is fixedly connected to the detection position. When starting to use a metal rod bending angle measuring device: The external handling mechanism transports the metal rod to be detected onto the bottom plate 1. Then, under the control of the external control system, the air cylinder 4 starts to work. The air cylinder 4 drives the pressing plate 5 to rotate and move towards the bottom plate 1. During this process, multiple pressing plates 5 cooperate with each other to press the metal rod on the bottom plate 1 tightly. At this time, the metal rod is completely positioned. Further, the external control system stops supplying power to the adsorbing member 8, so that the adsorbing member 8 no longer has magnetism, and the connecting plate moves away from the adsorbing member 8 under the action of the tensioning member 10. During this process, the moving member 7 drives the detecting member 12 to contact the side surface of the metal rod. Then, the detecting member 12 transmits the detected pressure signal to the external control system. Further, under the control of the external control system, the power member 7 drives the adsorbing member 8 and the detecting member 12 to rotate at a constant speed. During this process, the sensing surface of the detecting member 12 sequentially contacts different side surfaces of the metal rod. During this process, the detecting member 12 transmits the pressure signal from the side surface of the metal rod to it to the external control system. When the power member 7 rotates a certain angle, the detection process ends. Under the control of the external control system, the power member 7 stops working. Only when the pressure signal transmitted by the detecting member 12 during this process meets the set value can it be proved that the bending angle of the metal rod is qualified, otherwise it is proved that the bending angle of the metal rod is unqualified. Then, the air cylinder 4 drives the pressing plate 5 to move away from the metal rod to loosen the metal rod. The external handling mechanism transports the detected metal rod to the required position. During this process, the power member 7 drives the detecting component 6 to reset. Then, the external control system supplies power to the adsorbing member 8 to make it magnetic. The adsorbing member 8 adsorbs the connecting plate, thereby driving the detecting member 12 to approach the adsorbing member 8 and compressing part of the tensioning member 10. The external handling mechanism transports a new metal rod to be detected onto the bottom plate 1. Repeat the above process until the work is completed.

[0040] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field of the present utility model, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
