Description

Technical Field

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

[0002] Ball valve forgings refer to core components of ball valves formed through forging processes. These forgings improve the microstructure through metal plastic deformation, resulting in valve components with high strength, high sealing performance, and corrosion resistance. During processing, they are fixed using positioning devices.

[0003] For example, the Chinese authorized patent CN220389164U (a positioning device for processing ball valve forgings) includes a base and bolts. Multiple bolts are arranged on the outer side of the base. The bottom end of the base is fixedly connected to a suction cup, and the top end of the base is fixedly connected to a fixed seat. The top end of the fixed seat is rotatably connected to a support seat, and the top end of the support seat is rotatably connected to a U-shaped seat. The two sides of the U-shaped seat are threadedly connected to second screws on both sides. By rotating the round rod, the round rod drives the first screw to rotate through a bevel gear set. The first screw drives the rack to move, the rack drives the gear to rotate, and the gear drives the U-shaped seat to rotate. By rotating the direction of the first screw, the angle of the U-shaped seat is adjusted, thereby adjusting the angle of the ball valve forging. This allows for angle adjustment of the ball valve forging without repeated disassembly during processing, making the processing and adjustment of the ball valve forging more convenient.

[0004] However, in the current process of positioning ball valve forgings, most of them are fixed in one position by extrusion. This requires a corresponding processing device to be installed in a designated position, which is inconvenient for machines of different specifications and for adjusting the position of ball valve forgings of different sizes. Therefore, it does not meet the current needs. In response, we propose a positioning device for ball valve forging processing. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning device for ball valve forging processing, so as to solve the problem mentioned in the background art that when positioning ball valve forgings during processing, most of them are fixed in one position by extrusion. This requires a corresponding processing device to be installed in a designated position, which is inconvenient for machines of different specifications, and also inconvenient for adjusting the position of ball valve forgings of different sizes, resulting in poor flexibility.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for processing ball valve forgings, comprising: a base plate, an adjustment groove provided on the upper surface of the base plate, a rotating assembly provided at the upper end of the adjustment groove, a first positioning assembly provided on one side of the rotating assembly, a second positioning assembly provided on the other side of the rotating assembly, a column groove provided on the bottom surface of the adjustment groove, and multiple column grooves provided, the rotating assembly comprising a positioning sleeve and a pin, wherein the positioning sleeve is fitted over the pin, and the positioning sleeve and the pin are respectively inserted into the adjustment groove and the column groove.

[0007] Preferably, the outer walls of both sides of the positioning sleeve are provided with limiting strips, and the inner walls of both sides of the adjusting groove are provided with limiting grooves, with the limiting strips inserted into the limiting grooves.

[0008] Preferably, a ball bearing is provided on the outer side of the top end of the positioning sleeve, a rotating plate is provided on the outer side of the ball bearing, and the rotating plate is rotatably connected to the positioning sleeve through the ball bearing. A pull ring is provided on the top surface of the positioning sleeve.

[0009] Preferably, both the first positioning component and the second positioning component include a positioning plate. An arc-shaped insert is provided on the lower surface of one end of the positioning plate. An arc-shaped groove is provided on one side of the adjustment groove, and multiple arc-shaped grooves are provided. The arc-shaped insert moves along the arc-shaped groove. A fixing knob is provided at the upper end of one end of the positioning plate. A knob hole is provided on the bottom surface of the arc-shaped groove. One end of the fixing knob passes through the arc-shaped insert and is threadedly connected to the knob hole.

[0010] Preferably, both the first positioning component and the second positioning component further include a first extrusion plate and a second extrusion plate. One side of the first extrusion plate and the second extrusion plate is rotatably connected to a threaded rod via an external bearing. The threaded rod is externally threaded to a support plate.

[0011] Preferably, the other end surface of the positioning plate is provided with a threaded groove, and both sides of the rotating plate are provided with threaded posts, and the threaded posts are threadedly connected to the threaded groove.

[0012] Preferably, one end surface of the base plate is provided with an extension plate, and one end upper surface of the extension plate is provided with a roller groove, and a roller is provided inside the roller groove, and multiple rollers are provided.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model drives the first positioning component and the second positioning component to rotate through the rotating component. According to the size of the ball valve forging and the specifications and position of the actual processing device, the position of the first positioning component and the second positioning component is adjusted. When adjusting, the pull ring is pulled upward to separate the rotating component from the base plate and then insert it into the adjustment groove at the corresponding position. When inserting, the positioning sleeve and the insert are inserted into the adjustment groove and the column groove respectively, and the limiting strip is inserted into the limiting groove to limit the insert and prevent rotation, thereby improving the applicability and flexibility. When processing the ball valve forging on the first positioning component, the ball valve forging to be processed can be installed on the second positioning component to improve the processing efficiency. This solves the problem that when the existing ball valve forging is processed and positioned, it is mostly fixed in one position by extrusion. This requires the corresponding processing device to be installed in a designated position, which is inconvenient for machines of different specifications and for adjusting the position of ball valve forgings of different sizes, resulting in poor flexibility.

[0015] (2) By setting an extension plate at one end of the base plate, and installing multiple rollers inside the roller groove at one end of the extension plate, the first positioning component or the second positioning component is supported by the rollers when it rotates to the upper end of the extension plate. By relying on the rollers, the friction of the first positioning component and the second positioning component when rotating is reduced, and the rotation flexibility is improved.
