[0002] The end face flange of the valve is connected to the pipeline. Before drilling the end face of the valve, the end face circle on the valve end face needs to be fully polished to prevent uneven protrusions on the outer surface of the end face, which may cause workers to be stabbed when connecting the pipeline and drilling the end face. In the existing technology, sandpaper is often used to slowly grind and reduce burrs, but this method has slow processing speed, consumes manpower, and takes too much time when encountering large unevenness. Therefore, a valve end face circular grinding device is needed.

A grinding device is provided on the first support frame for performing circumferential grinding of the end face of the clamped valve.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] Example 1, as Figure 1 As shown, a valve end face circular grinding device includes a casing 1, a clamping mechanism 4 is fixedly connected to the middle of the inner cavity of the casing 1, a grinding mechanism 5 is provided on the right side of the clamping mechanism 4, U-shaped frames 2 are fixedly connected to the middle of the left and right ends of the casing 1, and a transport component 3 is commonly provided in the inner cavities of the two U-shaped frames 2. The outer surface of the transport component 3 passes through the middle of the left end and the middle of the right end of the casing 1 in sequence, and the transport component 3 is located directly below the clamping mechanism 4 and the grinding mechanism 5. A left-right symmetrical observation window 6 is provided on the upper side of the front end of the casing 1.

[0033] It should be noted that the transport component 3 is composed of a drive motor, a conveyor belt, two rollers, a pulley and a belt. When the drive motor is started, the two rollers are driven to rotate simultaneously with the cooperation of the pulley and the belt, thereby driving the conveyor belt to rotate. The specific installation method of the drive motor, the circuit connection method and the control method are all conventional designs, which are conventional design means of designers.

[0034] First, open the observation window 6 to fix the valve on the clamping mechanism 4, and determine the diameter of the valve end face. Adjust the grinding mechanism 5 according to the diameter of the valve end face. After the adjustment is completed, close the observation window 6, and start the clamping mechanism 4 and the grinding mechanism 5 at the same time, so that the grinding mechanism 5 grinds the circumference of the valve end face. The grinding generated during the grinding process falls into the transport component 3, and the grinding is discharged to the outside of the device through the transport component 3. The staff can observe the grinding condition of the valve in real time through the observation window 6.

[0035] In order to clamp the valve and drive the valve to rotate, Figure 2 and Figure 3 As shown, the clamping mechanism 4 includes a connecting frame 41, and the front and middle parts of the upper end of the connecting frame 41 are fixedly connected to the slide rails 44, and the outer surfaces of the two slide rails 44 are slidably connected to the clamping group 43. The lower left part of the clamping group 43 is fixedly connected to the electric telescopic rod 1 42, and the lower end of the electric telescopic rod 1 42 is fixedly connected to the left side of the upper end of the connecting frame 41. The front and rear ends of the connecting frame 41 are respectively fixedly connected to the front wall and rear wall of the inner cavity of the casing 1.

[0036] It should be noted that the specific installation method of the electric telescopic rod 42, the circuit connection method and the control method in the present invention are all conventional designs and are conventional design means of designers.

[0037] The valve is first clamped and fixed by the clamping group 43, and the diameter of the valve end face is determined. The grinding mechanism 5 is adjusted according to the diameter of the valve end face. After the adjustment is completed, the electric telescopic rod 42 is started, so that the electric telescopic rod 42 pushes the clamping group 43 to slide to the right on the outer surfaces of the two slide rails 44, so that the fixed valve moves to the appropriate position on the left side of the grinding mechanism 5, and the circumference of the valve end face is polished by the grinding mechanism 5. After the polishing is completed, the electric telescopic rod 42 is started, and the clamping group 43 is driven by the electric telescopic rod 42 to move to the left on the outer surface of the slide rail 44 to restore the initial position. Then the clamping group 43 will drive the valve to rotate, so that the circumference of the unpolished end face of the valve rotates to one side of the grinding mechanism 5, and then the clamping group 43 is driven to move to the right by the electric telescopic rod 42, so that the circumference of the unpolished end face of the valve moves to the appropriate position of the grinding mechanism 5, and the grinding mechanism 5 is started again to polish, thereby achieving the purpose of clamping the valve and driving the valve to rotate.

[0038] Further explanation, such as Figure 4As shown, the clamping group 43 includes a convex plate 431, a front-to-back symmetrical sliding groove 4391 is opened at the lower end of the convex plate 431, a mounting groove 1 432 is opened at the upper end in the vertical direction of the convex plate 431, a motor 1 433 is fixedly connected to the rear side of the inner cavity of the mounting groove 1 432, a gear plate 434 is fixedly connected to the output end of the motor 1 433, the outer surface of the gear plate 434 is meshed with a gear shaft 435, the outer surface of the gear shaft 435 is rotatably connected to the front side of the inner cavity of the mounting groove 1 432, an L-shaped bracket 4392 is fixedly connected to the rear side of the upper end in the horizontal direction of the convex plate 431, and an electric telescopic rod 3 439 is fixedly connected to the middle part of the rear end of the L-shaped bracket 4392. The output end of telescopic rod three 439 passes through the rear end of the L-shaped bracket 4392 and is fixedly connected to the limiting frame 438. The upper and lower sides of the outer surface of the limiting frame 438 are respectively slidably connected to the L-shaped bracket 4392 and the convex plate 431. The front side of the upper end of the L-shaped bracket 4392 is fixedly connected to the electric telescopic rod two 437. The output end of the electric telescopic rod two 437 and the upper end of the gear shaft 435 are both provided with a groove clamping plate 436. The lower end of the convex plate 431 is fixedly connected to the right side of the upper end of the connecting frame 41. The inner cavities of the two sliding grooves 4391 are respectively slidably connected to the outer surfaces of the two slide rails 44. The lower middle side of the left end of the convex plate 431 is fixedly connected to the output end of the electric telescopic rod one 42.

[0039] It should be noted that the specific installation methods, circuit connection methods, and control methods of the motor 1 433, the electric telescopic rod 2 437, and the electric telescopic rod 3 439 in the present invention are all conventional designs, which are conventional design means of designers. The output end of the electric telescopic rod 2 437 is rotatably connected to the middle part of the upper end of the groove clamping plate 436 located on the upper side. The groove clamping plates 436 that are symmetrical in upper and lower directions can clamp ordinary valves as well as right-angle three-phase valves.

[0040] In detail, first place the valve that needs end face circumference grinding into the inner cavity of the groove clamping plate 436 on the lower side, start the electric telescopic rod 2 437 to drive the groove clamping plate 436 on the upper side to move downward to the appropriate position, complete the clamping and fixing of the valve, then start the electric telescopic rod 1 42, so that the electric telescopic rod 1 42 drives the convex plate 431 to move to the right to the appropriate position on the outer surface of the slide rail 44 under the cooperation of the sliding groove 4391, and grinds the valve end face circumference through the grinding mechanism 5. When the end face circumference that is not ground needs to be ground, the electric telescopic rod 1 42 drives the convex plate 431 to move to the left to restore the initial position. At this time, start the motor 1 433 to drive the toothed disc 434 to rotate. The rotation drives the gear shaft 435 to rotate together, and the rotation of the gear shaft 435 causes the groove clamping plate 436 to drive the valve to rotate together, so that the unpolished end surface circumference of the valve rotates to the right, and the electric telescopic rod three 439 is started to push the limit frame 438 to get stuck at the rear ends of the two groove clamping plates 436, so that it cannot rotate. At this time, the electric telescopic rod one 42 is started again to push the convex plate 431 to the right to a suitable position, and the unpolished end surface circumference of the valve is polished by the polishing mechanism 5. The support of the groove clamping plate 436 by the limit frame 438 increases the stability of the valve during the polishing process. When the unpolished end surface circumference needs to be polished, there is no need to remove the valve and reinstall it, which saves time and improves work efficiency.

[0041] Example 2: Based on Example 1, this example implements the grinding of the valve end face, end face circumference, outer circle and inner hole, such as Figure 5 and Figure 6 As shown, the grinding mechanism 5 includes a base plate 51, a fixed plate 52 is fixedly connected to the middle of the upper end of the base plate 51, a motor 2 53 is fixedly connected to the lower side of the outer surface of the fixed plate 52, a rotating shaft 57 is rotatably connected to the upper side of the outer surface of the fixed plate 52, a transmission wheel 58 is fixedly connected to the output end of the motor 2 53 and the right end of the rotating shaft 57, the two transmission wheels 58 are connected by a belt, a fixed group 56 is fixedly connected to the left end of the rotating shaft 57, a grinding group 3 55 is provided on the left side of the fixed group 56, and a grinding group 1 54 is provided on the right side of the grinding group 3 55, and the lower end of the base plate 51 is fixedly connected to the right side of the upper end of the connecting frame 41.

[0042] It should be noted that the specific installation method, circuit connection method and control method of the motor 2 53 in the present invention are all conventional designs and are conventional design means of designers. In addition, rotation grooves are opened on the upper sides of the left and right ends of the fixed plate 52 to install the rotating shaft 57 without affecting the rotation of the rotating shaft 57 itself. Through square grooves are opened on the lower sides of the left and right ends of the fixed plate 52 to install the motor 2 53.

[0043] First, when the clamping group 43 clamps the valve and moves it to the right to the appropriate position on the left side of the grinding mechanism 5, the starting motor 2 53 is used in conjunction with the transmission wheel 58 and the belt to rotate the rotating shaft 57. The rotation of the rotating shaft 57 drives the fixed group 56 to rotate together. The rotation of the fixed group 56 drives the grinding group 3 55 and the grinding group 1 54 to rotate together, so that the grinding group 1 54 grinds the circumference of the valve end face. In addition, the valve end face can also be polished by the rotation of the grinding group 3 55. When the outer circle or inner hole of the valve needs to be polished, the grinding group 1 54 can be adjusted according to its diameter. The outer circle or inner hole of the valve can be polished by the rotation of the grinding group 1 54, and finally the purpose of grinding the valve end face, end face circumference, outer circle and inner hole is achieved, making the application range of the device wider.

[0044] Further explanation, such as Figure 7 As shown, the fixing group 56 includes a fixing plate 561, and a symmetrical clamping hole 567 is provided at the left end of the fixing plate 561. The two clamping holes 567 are provided with a mounting groove 2 564 on the side where the inner cavities are close to each other. The middle part of the inner cavity of the mounting groove 2 564 is rotatably connected with an adjusting component 1 566. The left side of the outer surface of the adjusting component 1 566 is meshed and connected with two connecting seats 565. The upper side and the lower side of the inner cavity of the two connecting seats 565 are rotatably connected with connecting rods 563. The two connecting rods 563 on the same side are provided with a top column 562 on the side away from the adjusting component 1 566. The outer surfaces of the two top columns 562 are close to each other and pass through the two clamping holes 567 respectively. The middle part of the right end of the fixing plate 561 is fixedly connected to the left end of the rotating shaft 57.

[0045] In detail, it should be noted that the adjusting component 1 566 is composed of a countersunk round rod and a bidirectional threaded rod. In the initial state, the upper and lower symmetrical top columns 562 are respectively stuck in the inner cavity of the clamping hole 567 on the same side to fix the grinding group 3 55. When it is necessary to replace the grinding group 3 55 and the grinding group 1 54, the adjusting component 1 566 is rotated by a special hexagonal wrench. Through the rotation of the adjusting component 1 566, the two connecting seats 565 are driven to move away from each other on the outer surface of the adjusting component 1 566. Through the movement of the two connecting seats 565 away from each other, the two upper and lower symmetrical connecting rods 563 are rotated, and then the top columns 562 on the upper and lower sides are driven to move closer to each other, so that the top columns 562 are disengaged from the inner cavity of the clamping hole 567. At this time, the grinding group 3 55 can be pulled out from the inner cavity of the two clamping holes 567, and the grinding group 3 55 or the grinding group 1 54 can be replaced, repaired, etc., making the device more flexible in use.

[0046] Further explanation, such as Figure 8As shown, the grinding group 3 55 includes a connecting plate 551, and the right end of the connecting plate 551 is fixedly connected to a circular hole card plate 552 that is symmetrical up and down. The outer surfaces of the two circular hole card plates 552 are respectively slidably connected to the inner cavities of the two card holes 567, and the outer surfaces of the two top columns 562 that are away from each other respectively pass through the inner cavities of the two circular hole card plates 552. A mounting hole 1 558 that is symmetrical up and down is opened in the middle of the left end of the connecting plate 551. The inner cavities of the two mounting holes 1 558 are both sleeved and connected with two bolts 3 559. The two bolts The left side of the outer surface of the third bolt 559 is engaged with the frosting disc 557, and the middle part of the right end of the connecting disc 551 is provided with a second threaded hole 553 symmetrically arranged in the upper and lower parts, and the middle part of the right end of the connecting disc 551 is provided with a third mounting groove 554, and the middle part of the left end of the connecting disc 551 and the middle part of the left end of the frosting disc 557 are both provided with a limiting hole 5591, and the front side of the left end of the connecting disc 551 and the front side of the left end of the frosting disc 557 are both provided with a limiting groove 556, and two fourth mounting grooves 555 are provided on the upper and lower sides of the middle part of the right end of the connecting disc 551.

[0047] In detail, the grinding group 1 54 is installed through the mounting groove 3 554, the mounting groove 4 555 and the threaded hole 2 553, so that the connecting plate 551 and the grinding group 1 54 can be assembled or disassembled. The rear side of the outer surface of the grinding plate 557 is clamped in the inner cavity of the two mounting holes 1 558 and fixed by the bolt 3 559. The two circular hole clamping plates 552 are respectively clamped in the inner cavity of the clamping holes 567, and the top column 562 passes through the clamping holes 567 and the circular hole clamping plate 552, so that the fixing group 56 fixes the grinding group 3 55. When only the valve end face needs to be polished, the grinding group 1 54 can be removed and the connecting plate 551 can be driven by the fixing group 56. The grinding disc 557 is rotated by the rotation of the connecting disc 551, so that the grinding disc 557 grinds the valve end face. When the circumference, outer circle or inner hole of the valve end face needs to be polished, the polishing group 54 can be installed and adjusted at the same time. With the cooperation of the limiting hole 5591 and the limiting groove 556, the connecting disc 551 is rotated by the fixing group 56, and the grinding group 54 is driven to complete the grinding operation of the valve end face circumference, outer circle or inner hole through the rotation of the connecting disc 551, so that the device has multiple grinding methods and increases the scope of application of the device.

[0048] Further explanation, such as Figure 9As shown, the grinding group 1 54 includes a rectangular plate 541, and a sliding groove 544 is opened in the middle of the left end and the front of the left end of the rectangular plate 541.
