The other travel switch 7 controls the transmission motor 504 to stop and the electric telescopic rod 506 to descend through the PLC controller 306. After the electric telescopic rod 506 descends, the electric clamping claw 507 stops clamping the valve flange, so that the valve flange falls into the valve flange conveying component 6, thereby achieving the effect of automatic feeding.

[0050] Embodiment 5

[0051] like Figure 8 As shown, according to the valve flange grinding device for valve processing according to an embodiment of the present invention, the valve flange conveying assembly 6 includes a conveying mounting frame 601, and the conveying mounting frame 601 is symmetrically and movably connected with a transmission roller 602 inside, and one end of the transmission roller 602 is connected to a servo motor 603, and the outer shell of the servo motor 603 is connected to the conveying mounting frame 601, and the outer periphery of the transmission roller 602 is matched with a transmission belt 604, and a sensor mounting frame 8 is installed on one side of the conveying mounting frame 601, and an infrared sensor 9 is installed inside the sensor mounting frame 8, and the servo motor 603 and the infrared sensor 9 are electrically connected to the PLC controller 306 respectively.

[0052] Through the above technical solution, by setting up the servo motor 603, the servo motor 603 can drive the transmission roller 602 to rotate in the conveying mounting frame 601. When the transmission roller 602 rotates, it can drive the transmission belt 604 to rotate in a circle, thereby achieving the function of valve flange transportation. When the valve flange moves to the side of the infrared sensor 9 in the sensor mounting frame 8, the infrared sensor 9 stops the servo motor 603 for a certain period of time through the PLC controller 306, thereby achieving the function of intermittently conveying the valve flange, which is convenient for automatic feeding and unloading.

[0053] Among them, one side of the PLC controller 306 is electrically connected to a manual switch, so as to achieve the function of manually controlling the rotating motor 201, the transmission motor 504, the electric telescopic rod 506, the electric clamp 507 and the servo motor 603.

[0054] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation mode of the present invention in the actual process is described in detail below, including the following steps:

[0055] Step 1: By setting up a servo motor 603, the servo motor 603 can drive the transmission roller 602 to rotate in the conveying mounting frame 601. When the transmission roller 602 rotates, it can drive the transmission belt 604 to rotate in a circle, thereby achieving the function of valve flange transportation. When the valve flange moves to the side of the infrared sensor 9 in the sensor mounting frame 8, the infrared sensor 9 stops the servo motor 603 for a certain period of time through the PLC controller 306, thereby achieving the function of intermittently conveying the valve flange, which is convenient for automatic feeding and unloading.

[0056] Step 2: Drive the electric clamp 507 to descend through the electric telescopic rod 506, clamp the valve flange delivered by the valve flange conveying component 6 and then rise, then the transmission motor 504 drives the transmission threaded rod 503 to rotate in the feed and discharge mounting frame 501, and when the transmission threaded rod 503 rotates, it can drive the moving slider 505 to slide along the transmission mounting groove 502, and when the moving slider 505 moves and contacts one of the travel switches 7, the travel switch 7 controls the transmission motor 504 to stop and the electric telescopic rod 506 to descend through the PLC controller 306. After the electric telescopic rod 506 descends, the bottom of the valve flange is first polished for a certain period of time by the magnetic polishing component 2, and then the electric clamp 507 stops clamping the valve flange The electric telescopic rod 506 is held, so that the valve flange falls into the periphery of the limit rod 11 in the magnetic grinding barrel 205, thereby achieving the effect of automatic feeding. After the grinding is completed, the electric telescopic rod 506 rises and the electric clamping claw 507 clamps the valve flange out of the magnetic grinding barrel 205, and then the transmission motor 504 drives the transmission threaded rod 503 to reverse, so that the moving slider 505 returns, and the moving slider 505 returns to contact another travel switch 7. The other travel switch 7 controls the transmission motor 504 to stop and the electric telescopic rod 506 to descend through the PLC controller 306. After the electric telescopic rod 506 descends, the electric clamping claw 507 stops clamping the valve flange, so that the valve flange falls into the valve flange conveying component 6, thereby achieving the effect of automatic feeding.

[0057] Step three: After the valve flange enters the magnetic grinding barrel 205, the magnetic grinding barrel 205 drives the trigger installation ring 301 to descend. After the trigger installation ring 301 descends, the trigger installation ring 301 drives the trigger connecting rod 302 to descend, and then the trigger connecting rod 302 descends in the trigger sleeve 303. Then the trigger connecting rod 302 drives the contact pad 305 to apply pressure to the pressure sensor 304. The pressure sensor 304 starts the rotating motor 201 through the PLC controller 306, thereby achieving the function of automatically grinding the valve flange.

[0058] Step 4: By rotating the motor 201, the rotating motor 201 can drive the rotating shaft 202 to rotate. When the rotating shaft 202 rotates, it can simultaneously drive the magnetic rotating disk 203 and one of the transmission sprockets 209 to rotate. When the magnetic rotating disk 203 rotates, it can drive the permanent magnet 204 to rotate, thereby forming a rotating magnetic field. At this time, the grinding steel needle in the magnetic grinding barrel 205 moves, thereby achieving the effect of grinding the valve flange in the magnetic grinding barrel 205. When one of the transmission sprockets 209 rotates, it drives the other transmission sprocket 209 to rotate through the transmission chain 210. When the other transmission sprocket 209 rotates, it can drive the transmission shaft 208 to rotate in the transmission fixed frame 10. When the transmission shaft 208 rotates, it can drive the first transmission bevel gear 211 to rotate, and the first transmission bevel gear 211 can rotate. When the first transmission bevel gear 211 rotates, it can drive the second transmission bevel gear 212 to rotate. When the second transmission bevel gear 212 rotates, it can drive the reciprocating screw 213 to rotate in the screw fixing frame 216. At this time, the reciprocating screw 213 reciprocates under the action of the screw fixing matching block 214 and the matching block fixing frame 215. When the reciprocating screw 213 reciprocates, it can drive the movable sliding plate 206 to reciprocate along the movable sliding groove 207 through the screw fixing frame 216, thereby achieving the reciprocating movement of the rotating motor 201, the rotating shaft 202, the magnetic rotating disk 203 and the permanent magnet 204. At this time, the permanent magnet 204 will also reciprocate while rotating, so that the grinding steel needle will also reciprocate while rotating in the magnetic grinding barrel 205, thereby greatly improving the grinding effect of the valve flange.

[0059] Step 5: When the sliding plate 206 moves back and forth, it will also drive the rolling mounting plate 402 in the rolling mounting groove 401 to move back and forth. When the rolling mounting plate 402 moves back and forth, the rotating wheel 404 can be driven to roll in the rolling mounting groove 401 through the rotating rod 403, thereby achieving the effect of stable movement of the sliding plate 206.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
