Description

Technical Field

[0001] This utility model relates to the field of valve component processing technology, and in particular to a polishing machine for processing valve discs. Background Technology

[0002] The disc is a key component in a valve, usually referring to a rotatable disc structure in the valve body. The disc is installed in the cylindrical channel of the valve body and rotates around its axis to open and close, used to control the flow of fluid or to regulate it. It is an important part of the valve assembly, and its surface needs to be polished during the manufacturing process.

[0003] Existing disc polishing equipment suffers from the following drawbacks: Current automated disc polishing equipment uses a robotic arm to hold the disc and polish it against a sanding belt. The robotic arm operates according to preset values, but different discs require different polishing positions and durations. Automated equipment struggles to achieve comprehensive and precise polishing of different disc surfaces. Therefore, most operations still rely on manual operation, where the disc is held by hand and the sanding belt is in contact with the blade. This method presents safety hazards and is inconvenient due to the fixed position of the sanding belt and the direct hand contact with the disc. To address these issues, we propose a polishing machine for valve disc processing. Utility Model Content

[0004] The main objective of this invention is to provide a polishing machine for processing valve discs. Through the polishing mechanism set on the top of the frame, the angle of the abrasive belt can be adjusted during the polishing process so that it can contact different positions on the disc surface. At the same time, the operator's hand can be kept away from the polishing position during operation, which improves safety and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A polishing machine for processing valve discs includes a frame, and a polishing mechanism for processing the discs is provided on the top of the frame, comprising: Motor: Mounted on one side of the top of the frame by fasteners as the mechanical power source for the polishing mechanism, with a drive wheel installed at its power output end; Movable frame: Movablely installed on one side of the top of the frame. The top of the frame has an arc-shaped groove and the side of the movable frame is welded with bolts that penetrate the inside of the arc-shaped groove. The side of the movable frame is equipped with a movable wheel corresponding to the position of the drive wheel, and a sanding belt for disc grinding is sleeved between the drive wheel and the movable wheel. Spring A: Installed inside the arc-shaped groove and its two ends are respectively welded to the end of the inner wall of the arc-shaped groove and the side of the bolt, which plays an auxiliary role in resetting the position of the movable frame. At the same time, a tie rod is welded to the side of the movable frame. Bracket: It is fixed to the side of the frame by fasteners and has a groove structure on the side for the sanding belt to pass through. The disc clamp is installed through the bracket.

[0006] Furthermore, it also includes a base, the top of which is fixed to the bracket by fasteners, and inserts are symmetrically welded to both sides of the top of the base. A movable seat is movably connected to the top of the base, and a pin is welded to the bottom of the movable seat, with its end inserted into the insert. A fixed sleeve is vertically welded to the top of the movable seat, and a movable sleeve is movably connected to the top of the fixed sleeve. A rod is welded to the bottom of the movable sleeve, inserting into the fixed sleeve, and a spring B is installed around the outer periphery of the rod, located inside the fixed sleeve. Positioning pins are welded to the sides of both the fixed sleeve and the movable sleeve, inserting into the valve stem mounting position on the side of the disc. The bottom of the movable seat is connected to a... The pin is inserted into the insert, and the pin and insert form a rotating shaft structure, allowing the movable seat to rotate at an angle on the top of the base. The clamping assembly is located on the side of the movable seat. Before processing the disc plate, the movable sleeve is pulled up, causing the insert rod to move upward and the spring B to be compressed, aligning the valve stem installation position on the side of the disc plate with the positioning post. Then, the movable sleeve is released, causing the spring B to drive the movable sleeve downward. The positioning posts on the sides of the fixed sleeve and the movable sleeve are respectively inserted into the two ends of the valve stem installation position to fix the position of the disc plate. At the same time, during the processing, the angle of the disc plate can be adjusted by adjusting the angle of the movable seat.

[0007] Furthermore, the bolt surface is screwed with a nut for adjusting the tightness of the movable frame; when the sanding belt angle needs to be adjusted during processing, the nut can be loosened to control the movement of the movable frame during processing, and the position of the movable frame can be fixed by tightening the nut.

[0008] Furthermore, a controller is installed on the top of the frame near the motor, and the controller's control terminal is connected to the motor's control terminal; the controller is used to regulate the starting and stopping operation of the motor.

[0009] Furthermore, the fixed sleeve is symmetrically welded with limiting posts on both sides of the positioning post; when the positioning post fixes the disc plate, the limiting posts fit exactly against the surface of the disc plate and are located on both sides of the positioning post, which can limit the angle of the disc plate and prevent it from deflecting around the positioning post.

[0010] Furthermore, a rocker arm is horizontally welded to the side of the fixed sleeve away from the positioning post; the angle of the movable seat can be adjusted through the rocker arm structure.

[0011] Compared with the prior art, this utility model has the following advantages: A movable frame is installed on the top of the frame via an arc groove and bolts. The driven wheel of the positioning sanding belt is installed on the side of the movable frame via bearings. The movable frame can slide along the arc groove, driving the driven wheel to move and thus adjusting the angle of the sanding belt. When polishing the disc, it is fixed on the clamp on the top of the bracket. During processing, the position of the sanding belt is adjusted by the pull rod, and the angle of the disc is adjusted by the rocker arm. The combination of these two methods allows the sanding belt to perform fine polishing on different parts of the disc surface during processing. At the same time, the operator's hands are away from the polishing position during operation, eliminating the need to hold the disc, thus ensuring the flexibility of the polishing operation. This design significantly improves operational safety. The bottom of the movable seat is inserted into the insert cylinder via a pin. The pin and insert cylinder work together to form a rotating shaft structure, allowing the movable seat to rotate at an angle on the top of the base. The clamping assembly is located on the side of the movable seat. Before processing the disc plate, the movable sleeve is pulled up, causing the insert rod to move upward and spring B to be compressed. This aligns the valve stem installation position on the side of the disc plate with the positioning post. Then, the movable sleeve is released, causing spring B to drive the movable sleeve downward. The positioning posts on the sides of the fixed sleeve and the movable sleeve are inserted into the valve stem installation positions at both ends, thus fixing the disc plate position. During processing, the angle of the disc plate can be adjusted by adjusting the angle of the movable seat. Attached Figure Description
