Description

Technical Field

[0001] This utility model relates to the field of valve ball processing technology, specifically a valve ball surface treatment device. Background Technology

[0002] A ball valve is a type of valve in which the opening and closing element (ball) is driven by the valve stem, which rotates around the axis of the ball valve. This type of valve is mainly used for fluid regulation and control. Ball valves were first introduced in the 1950s. With the rapid development of science and technology and the continuous improvement of production processes and product structures, it has become a major type of valve. In pipelines, ball valves are mainly used to cut off, distribute, and change the flow direction of the medium. It only requires a 90-degree rotation and a very small torque to achieve a tight closure. When machining the valve ball, its surface needs to be polished.

[0003] Chinese Patent Publication No. CN117620869A discloses a valve ball manufacturing and processing device, including a first motor and a rotating assembly. The rotating assembly for direction adjustment is located behind the first motor. The rotating assembly includes an output shaft, a rotating disk, a connecting rod, a sliding sleeve, a support rod, a first rotating rod, a mounting rod, and a second rotating rod. The rotating disk is located behind the output shaft, the connecting rod is located behind the rotating disk, and the sliding sleeve is located behind the connecting rod. This application drives the first motor to move the sliding sleeve, thereby indirectly moving the polishing block on the surface of the ball valve. This allows the device to change the polishing position during operation, resulting in uniform surface processing of the ball valve. The device can complete the surface processing of the ball valve without changing the fulcrum, making it convenient and easy for operators to use.

[0004] However, the diameter of the locking block in the above-mentioned patent is fixed, and since the inner diameter of the valve ball is different, different locking blocks need to be replaced. Therefore, it is inconvenient to fix different models of valve balls, which makes the applicability of the device low and reduces the practicality of the device. To this end, we propose a valve ball surface treatment device. Utility Model Content

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This valve ball surface treatment device works by fitting the valve ball onto the outside of the mounting cylinder. Turning the knob drives the bidirectional screw to rotate, causing the moving discs to move away from each other. This causes the connecting rod to deflect vertically, which in turn causes the connecting seat to move vertically, moving the clamping plate. The clamping plate then presses against the inner wall of the valve ball, fixing the valve ball in place. This facilitates the fixing of valve balls with different inner diameters and makes it easier to process valve balls with different inner diameters. This increases the applicability and practicality of the device.

[0021] 2. This valve ball surface treatment device, through the start of the drive motor, drives the turntable to rotate, causing the connecting shaft to deflect, thereby squeezing the connecting groove, causing the deflection plate to drive the rotating shaft to rotate back and forth, which in turn causes the connecting plate to rotate back and forth, causing the polishing disc to deflect back and forth, thereby increasing the polishing range, preventing polishing dead corners, and is easy to operate, making it convenient for staff to operate and improving the practicality of the device.

[0031] This utility model provides a valve ball surface treatment device, which facilitates the fixing of valve balls with different inner diameters and makes it easier to process valve balls with different inner diameters. This increases the applicability and practicality of the device. Please refer to [link / reference]. Figure 1 It includes a workbench 100, support legs 200, support base 300, fixing mechanism 400, support rod 500 and swing mechanism 600;

[0032] Please refer to it again. Figure 1 The workbench 100 is used to install the support legs 200, support base 300, fixing mechanism 400, support rod 500 and swing mechanism 600;

[0033] Please refer to it again. Figure 1 The support feet 200 are fixed at the four corners of the bottom of the workbench 100, the support base 300 is fixed at the rear top of the workbench 100, the top of the support base 300 is fixed with a rotating motor 310, the fixing mechanism 400 is fixed at the end of the output shaft of the rotating motor 310, the swing mechanism 600 is connected to the outside of the workbench 100, and the support rod 500 is symmetrically connected to the top of the swing mechanism 600.

[0034] Please refer to it again. Figure 1 An electric telescopic rod 510 is fixed to the top of the support rod 500. An installation plate 520 is fixed to the end of the output shaft of the electric telescopic rod 510. A polishing motor 530 is fixed to the middle of one side of the installation plate 520. A polishing disc 540 is fixed to the end of the output shaft of the polishing motor 530.

[0035] Please refer to it again. Figure 2 The fixing mechanism 400 includes a mounting cylinder 410 fixed to the end of the output shaft of the rotating motor 310. A bidirectional screw 420 is rotatably inserted through the middle of one side of the mounting cylinder 410. A knob 430 is fixed to one end of the bidirectional screw 420. Two movable disks 440 are screwed to the outer side of the bidirectional screw 420.

[0036] Please refer to it again. Figure 2 The outer wall of the movable disk 440 is evenly provided with rotating grooves 441, and a connecting rod 450 rotates inside the rotating grooves 441. The outer side of the mounting cylinder 410 is evenly provided with clamping plates 460, and a connecting seat 470 is symmetrically fixed on one side of the clamping plate 460.

[0037] In summary, by fitting the valve ball onto the outside of the mounting cylinder 410, rotating the knob 430 drives the bidirectional screw 420 to rotate, causing the moving discs 440 to move away from each other. This causes the connecting rod 450 to deflect vertically, which in turn causes the connecting seat 470 to move vertically, thus moving the clamping plate 460. The clamping plate 460 then abuts against the inner wall of the valve ball, fixing the valve ball in place. This facilitates the fixing of valve balls with different inner diameters and makes it easier to process valve balls with different inner diameters. This results in a high degree of applicability and improved practicality of the device.

[0038] Please refer to it again. Figure 2 The fixing mechanism 400 also includes a through groove 411 evenly opened through the outside of the mounting cylinder 410, and a fastening bolt 431 is threaded through one side of the knob 430.

[0039] Please refer to it again. Figure 2 One end of the connecting rod 450 rotates inside the connecting seat 470, and the connecting rod 450 is located inside the through groove 411.

[0040] Please refer to it again. Figure 2 The outer side of the knob 430 is provided with anti-slip texture, and the outer side wall of the clamp 460 is fixed with a rubber pad.

[0041] Please refer to it again. Figure 4 The swing mechanism 600 includes a rotating shaft 610 that rotates through the top center of the worktable 100. A connecting plate 620 is fixed to the top of the rotating shaft 610, and a deflection plate 630 is fixed to the bottom of the rotating shaft 610. A connecting groove 640 is provided through the top of the deflection plate 630. A mounting bracket 650 is fixed to the bottom of the worktable 100. A drive motor 660 is fixed to the middle of the bottom of the inner side of the mounting bracket 650. A turntable 670 is fixed to the end of the output shaft of the drive motor 660, and a connecting shaft 680 is fixed to the top edge of the turntable 670.

[0042] Please refer to it again. Figure 4 The support rod 500 is symmetrically fixed to the top of the connecting plate 620, and the deflection circumference diameter of the connecting shaft 680 is smaller than the length of the connecting groove 640.

[0043] Please refer to it again. Figure 5 The connecting shaft 680 is located inside the connecting groove 640, and the outer side wall of the connecting shaft 680 is in contact with the inner side wall of the connecting groove 640.

[0044] In summary, by starting the drive motor 660, the turntable 670 is driven to rotate, causing the connecting shaft 680 to deflect, thereby squeezing the connecting groove 640. This causes the deflection plate 630 to drive the rotating shaft 610 to rotate back and forth, which in turn causes the connecting plate 620 to rotate back and forth, causing the polishing disc 540 to deflect back and forth. This increases the polishing range, prevents polishing dead corners, and is easy to operate, making it convenient for staff to use and improving the practicality of the device.

[0045] In practical use, when processing the valve ball, those skilled in the art will fit the valve ball onto the outside of the mounting sleeve 410, positioning the valve ball between the two polishing discs 540. Rotating the knob 430 will drive the bidirectional screw 420 to rotate, causing the moving discs 440 to move away from each other. This will cause the connecting rod 450 to deflect vertically, thereby moving the connecting seat 470 vertically and causing the clamping plate 460 to move. The clamping plate 460 will then press against the inner wall of the valve ball, fixing it in place. Afterwards, the fastening bolt 431 will be tightened to secure the knob 430. The electric telescopic rod 510 will then be activated, allowing the polishing discs to... When 540 contacts the valve ball, the rotary motor 310, polishing motor 530, and drive motor 660 are started. The start of the rotary motor 310 drives the fixed mechanism 400 to rotate, causing the valve ball to rotate. The start of the polishing motor 530 drives the polishing disc 540 to rotate, polishing the valve ball. The start of the drive motor 660 drives the turntable 670 to rotate, causing the connecting shaft 680 to deflect, thereby squeezing the connecting groove 640. This causes the deflecting plate 630 to drive the rotating shaft 610 to rotate back and forth, which in turn causes the connecting plate 620 to rotate back and forth, causing the polishing disc 540 to deflect back and forth, thereby increasing the polishing range.
