Description

Technical Field

[0001] The invention belongs to the technical field of valve production, and in particular relates to a valve body polishing device for valve production. Background Art

[0002] The existing valve body grinding device used in valve production is a device specifically designed for fine-finishing the internal surface of valves, ensuring that the inner wall of the valve body is smooth and burr-free, meeting stringent usage requirements. This device primarily consists of a fixing system and a grinding mechanism. During operation, the valve body is first firmly fixed vertically by the fixing device. The grinding disc is then driven to rotate and gradually move downward to grind the inner arc wall of the valve body. This device utilizes its precise grinding process to effectively remove rough areas on the inner wall of the valve body, improving the surface finish and thus ensuring good sealing and durability of the valve. Valve body grinding devices used in valve production have become an indispensable key equipment in the valve manufacturing process and play an important role in ensuring product quality.

[0003] Existing valve body grinding devices used in valve production first secure the valve body with a fixture, then drive the grinding disc to rotate and gradually move downward to grind the inner arc wall of the valve body to a smooth surface that meets user requirements. However, because the valve body is fixed vertically, only one grinding mechanism can be used to grind the inner wall of the valve body. Since only one grinding mechanism can be used, the entire valve body inner wall must be polished step by step. This results in a long grinding process, especially when processing large or complex-shaped valve bodies, and efficiency issues are more prominent. Summary of the Invention

[0004] In view of this, the present invention addresses the deficiencies in the prior art and provides a valve body polishing device for valve production, which can fix the valve body laterally and use multiple sets of polishing mechanisms to polish the inner wall of the valve body at the same time, while also scraping off burrs that have not been completely removed, effectively reducing the time required for polishing the inner wall of the valve body and significantly improving the efficiency of valve body polishing.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a valve body polishing device for valve production, including a box body, a plurality of sliding connecting plates are slidingly arranged on the upper inner end of the box body, a slide rail is arranged inside each sliding connecting plate, the sliding connecting plate and the slide rail are fixed by welding, a mounting shell is slidingly arranged inside each slide rail, a grinding disk is rotatably arranged inside each mounting shell through a rotating column, a plurality of driving boxes are arranged on the upper end of the box body, a rotating drum is rotatably arranged inside the plurality of driving boxes, a placing frame plate is arranged between the interiors of the plurality of rotating drums, a plurality of guide columns are slidingly arranged inside the placing frame plate, a clamping fixing plate is respectively arranged between the plurality of adjacent guide columns on the left and right, the front and rear positions of the two clamping fixing plates correspond, a rotating driving mechanism for driving the placing frame plate to rotate is arranged inside the driving box, and an adaptive cleaning mechanism is respectively provided at the upper end of the mounting shell.

[0006] As a further improvement of the present invention, the rotation drive mechanism includes gears arranged inside two drive boxes that are rotated by a rotating column, a gear ring is provided on the outer arc surface of each rotating cylinder, and multiple gears are respectively engaged with adjacent gear rings.

[0007] The cam is connected to the upper and lower ends of the cams by a toothed connection, and the toothed connection is connected with the toothed connection of the cam and the toothed connection of the cam.

[0008] As a further improvement of the present invention, multiple support mounting plates are provided at the lower end of the box body, the box body and the support plates are fixed by welding, multiple fixed mounting holes are provided inside the multiple support mounting plates, and the front side of the box body is hinged with multiple door panels through hinges, and the front sides of the multiple door panels are provided with handles.

[0009] As a further improvement of the present invention, the adaptive cleaning mechanism includes cavity frames respectively arranged at the upper ends of the two mounting shells, sliding columns are slidably arranged inside the multiple cavity frames, cleaning plates are respectively arranged at the upper ends of the multiple sliding columns, rectangular plates are respectively arranged on the outer arc surfaces of the multiple sliding columns, springs are respectively arranged between the multiple rectangular plates and the cavity frames, and the multiple springs are respectively arranged on the outer arc surfaces of the corresponding sliding columns.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] First, the handwheel is rotated to drive the screw rod three to rotate, so that the clamping and fixing plates on both sides approach each other under the restriction of the guide column to achieve clamping and fixing of the valve body, and then the motor one is controlled to run, and the output shaft drives the grinding disk on the rotating column to rotate, and then the motor two on both sides is controlled to run. The output shaft drives the screw rod two on both sides to rotate, and drives the grinding disks on the sliding connecting plates on both sides to approach each other and enter the interior of the valve body, and then the operation of the motor two is turned off, and then the motor three on both sides is controlled to run to make the screw rod two rotate, and then drive the grinding disk on the mounting shell to move downward and contact the inner wall of the valve body, and then the operation of the motor three is turned off, and the inner wall of the valve body is polished with the rotating grinding disk, and valves of different sizes can be fixed for polishing.

[0012] Secondly, by controlling the operation of motor four, the output shaft drives the gear on the rotating column to rotate, and then the rotating drum on the gear ring rotates, driving the valve body placed on the frame plate to rotate, and then by controlling the operation of motor two, the grinding discs on both sides are made to approach each other, and at the same time, by controlling the operation of motor three, the grinding discs are made to move up and down flexibly along the protrusions and depressions on the inner wall of the valve body. When the grinding disc on the left and the grinding disc on the right are about to contact each other, the motor two on the left is controlled to move the grinding disc on the left to the left, and then the motor two on the right is controlled to move the grinding disc on the right to the left, thereby realizing comprehensive grinding of the inner wall of the valve body. The valve body can be fixed horizontally, and multiple sets of grinding mechanisms are used to grind the inner wall of the valve body at the same time, and burrs that have not been completely removed can also be scraped off, which effectively reduces the time required for grinding the inner wall of the valve body and significantly improves the efficiency of valve body grinding.

[0013] Thirdly, when the mounting shells on both sides are driven toward each other by motor 2, the cleaning plates on both sides slide downward due to their bent shape under the restriction of the guide column, so that the cleaning plates enter the interior of the valve body, and through the elastic rebound and compression of the spring, the cleaning plates can continuously contact the interior of the valve body and cooperate with the rotating valve body to clean and scrape the burrs, ensuring that the interior of the valve body is polished more cleanly.

[0014] Fourthly, the grinding device can be supported by the support mounting plate, and the fixed mounting holes can be used to fix it to the ground with fixing bolts, ensuring that the grinding device operates more stably. At the same time, the door panel can be opened through the handle to store materials inside for easy use. BRIEF DESCRIPTION OF THE DRAWINGS
