[0002] In the field of valve bending and locking cores, the valve is a device that provides a flow channel for gas, which needs to be bent before being used in conjunction with the valve core assembly. Usually, the valve is supported by a support seat, and the clamping and resisting effect of the second push plate and the resisting head is utilized to make the turntable drive the bending rod to rotate and push the clamped and resisted valve to bend and deform, so as to achieve bending, and then the locking core mechanism is utilized to lock the valve core into the bent valve.

[0155] The bracket 60 is fixed to a side of the C plate 54 close to the support 1;

[0156] The laser pen 61 is fixed through a side of the bracket 60 away from the C-plate 54;

[0157] The reflector 64 is rotatably connected to the bracket 60 and is located above the movable groove 55 and the pushing plate 67;

[0158] The arc plate 42 is fixed to one end of the reflector 64 close to the arc push plate 59.

[0159] In actual application of this embodiment, the C plate 54 can provide a stable support for the bracket 60. A rotating rod 62 is installed inside the bracket 60. A rotating sleeve 63 is rotatably mounted on the outer side of the rotating rod 62. The rotating sleeve 63 is fixedly connected to the end of the reflector 64 close to the laser pen 61. The bracket 60 can provide a stable support for the laser pen 61. After the laser pen 61 is started, it will emit colored light to the reflector 64. The reflector 64 can push the rotating sleeve 63 to rotate together on the outer side of the rotating rod 62 under the action of external force. The arc plate 42 can provide a guiding effect for the valve behind the lock core, so that when it moves in a direction away from the semicircular plate 35, the arc plate 42 pushes the reflector 64 to rotate, so that the valve behind the lock core can move below the reflector 64.

[0160] When the lock core is finished working, the valve stem behind the lock core can be placed inside the movable groove 55 according to the actual needs. At the same time, the valve stem behind the lock core will contact the pushing plate 67 through one end under the action of external force, and use the curvature of the pushing plate 67 to push the pushing plate 67 to move in the direction away from the guide groove 57, and stretch the third spring 66 to store energy during the movement until the valve stem behind the lock core is completely placed in the inner side of the movable groove 55.

The position where the light is irradiated on the transparent ruler 56 is related to the angle of the reflector 64. When the light is irradiated on the transparent ruler 56, a light spot will appear on the transparent ruler 56 for the staff to observe. At this time, the staff can read the size by observing the position of the scale line set on the transparent ruler 56 corresponding to the light spot, and the size of the valve nozzle behind the lock cylinder is reflected by the size, so as to detect the size of the valve nozzle behind the lock cylinder more finely.

[0161] Working principle: the support feet 13 provide a stable support for the machine base 5 and the base 6, so that the machine base 5 can stably support the first straight vibrator 7, the support seat 1 and the servo motor 2. The servo motor 2 drives the turntable 3 to rotate, and the turntable 3 drives the bending rod 4 to rotate. The bending rod 4 uses the rotational power to contact the clamped and fixed valve nozzle and push the valve nozzle to bend to achieve bending. The first straight vibrator 7 array transports the valve nozzle to the inner side of the guide cylinder 8. Under the action of gravity, the valve nozzle slides along the guide cylinder 8 to the inner side of the movable groove 20. The second straight vibrator 9 array transports the valve core to the inner side of the tray 10. The lock core seat 11 stably supports the clamp 12 and the electric rod 14. The clamp 12 and the clamp 17 clamp the valve core and the valve nozzle so that the lock core positions of the valve core and the valve nozzle correspond to each other. The electric rod 14 provides a stable support for the low-speed motor 16 through the first push plate 15. The high-speed motor 16 drives the clamp 17 to rotate at a low speed, so that the valve mouth is inserted into the bent valve mouth during the translation process, and the valve core is interlocked with the bent valve mouth by using the rotational power to realize the locking core operation. The staff can control the operation of all electrical facilities of the device through the controller 19, inject the valve core into the second straight vibrator 9, inject the valve mouth into the first straight vibrator 7, start the first straight vibrator 7 and the second straight vibrator 9, so that the valve mouth and the valve core are respectively transported in an array. After clamping and fixing the valve mouth moved to the movable groove 20, start the servo motor 2, so that the servo motor 2 drives the turntable 3 to rotate, so that the turntable 3 drives the bending rod 4 to rotate, and in the process of rotation, cooperates with the resistance effect of the resistance head 45 to push and bend the clamped valve mouth. The more the bending rod 4 rotates beyond one hundred and eighty degrees, the greater the bending angle.After bending, the servo motor 2 needs to rotate in the opposite direction, and drive the bending rod 4 to rotate and reset through the turntable 3. When the valve mouth is bent and its clamping and fixing are released, the control robot arm 18 will clamp and move the bent valve mouth into the clamp 12, so that the clamp 12 clamps and fixes the bent valve mouth, and the control robot arm 18 takes the valve core from the tray 10 and moves it into the clamp 17, and makes the clamp 17 clamp the valve core to ensure that the lock core position of the valve core and the valve mouth is matched, and the control electric rod 14 is extended, so that the electric rod 14 pushes the clamp 17 and the clamped valve core to the lock core position of the clamped bent valve mouth through the first push plate 15 and the low-speed motor 16 under the support of the lock core seat 11, and starts the low-speed motor 16 at the same time, so that the low-speed motor 16 drives the clamp 17 and the clamped valve mouth to rotate slowly under the support of the first push plate 15, so that the valve mouth is inserted into the bent valve mouth during the translation process, and the valve mouth is inserted into the bent valve mouth during the translation process. Use rotational power to interlock the valve core with the bent valve mouth to achieve locking core operation. The staff can use the support feet 13 to firmly place the machine base 5 and the base 6 at the work site according to the actual needs, and operate the controller 19 to control the operation of all electrical facilities of the device according to the actual needs. The staff can inject the valve core into the second straight vibrator 9 and the valve mouth into the first straight vibrator 7 according to the actual needs, and start the first straight vibrator 7 and the second straight vibrator 9, so that the first straight vibrator 7 and the second straight vibrator 9 respectively convey the valve mouth and the valve core in an array. After clamping and fixing the valve mouth moved to the movable groove 20, start the servo motor 2, so that the servo motor 2 drives the turntable 3 to rotate, so that the turntable 3 drives the bending rod 4 to rotate, and cooperates with the resistance effect of the resistance head 45 to push and bend the clamped valve mouth during the rotation. The more the bending rod 4 rotates beyond one hundred and eighty degrees, the greater the bending angle. After bending, the servo motor 2 needs to rotate in the opposite direction, and the turntable 3 drives the bending rod 4 to rotate and reset. When the valve mouth is bent and its clamping is released, the control arm 18 clamps and moves the bent valve mouth into the clamp 12, so that the clamp 12 clamps and fixes the bent valve mouth. The control arm 18 takes the valve core from the tray 10 and moves it to the clamp 17, and the clamp 17 clamps the valve core to ensure that the lock core position of the valve core and the valve mouth is matched, and the control rod 14 is extended to make the valve core and the valve mouth lock core match. With the support of the lock core seat 11, the electric rod 14 pushes the clamp 17 and the clamped valve core to translate toward the lock core position of the clamped bent valve mouth through the first push plate 15 and the low-speed motor 16, and at the same time starts the low-speed motor 16, so that the low-speed motor 16 drives the clamp 17 and the clamped valve mouth to rotate slowly with the support of the first push plate 15, so that the valve mouth is inserted into the bent valve mouth during the translation process, and the rotational power is used to interlock the valve core with the bent valve mouth to realize the lock core operation.
