Description

Technical Field

[0001] This utility model belongs to the field of flange processing technology, and in particular relates to a pipe flange processing device. Background Technology

[0002] A flange, also called a flange disc or flange, is generally designed in the shape of a disc. Flanges are parts that connect shafts to each other, used for connecting pipe ends, and also used on equipment inlets and outlets for connecting two pieces of equipment, such as speed reducer flanges. During the flange production process, flanges often need to be further processed, such as grinding the flange circumference or cutting the edges.

[0003] Existing patents disclose a multi-station machine tool for flange processing, relating to the field of flange processing machine tool technology. In this invention, a flange processing device is mounted on a lifting control console. This device has multiple processing stations, each equipped with a set of flange processing components. A flange positioning control system is installed inside the machine tool body. This system includes a load-bearing power mechanism, comprising a transverse load-bearing shaft and a transverse power shaft. An array of flange positioning mechanisms is arranged on the transverse load-bearing shaft, and the flange positioning mechanisms are fixedly connected to the transverse load-bearing shaft, with adjacent flange positioning mechanisms spaced equidistantly. Each set of flange positioning mechanisms corresponds to one flange processing component, allowing simultaneous control of the intermittent rotation of multiple flanges to be processed. Under the action of the flange processing components, automated processing of the flanges is achieved, meeting the needs of batch flange processing and improving processing efficiency. However, this equipment only grinds the circumferential surfaces of the flange, neglecting the processing of the flange end faces. Previous technologies involved overly complex processing of the flange end faces, resulting in low processing efficiency and hindering flange processing. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a pipe flange processing device that can conveniently process the end face of the flange and improve the processing efficiency of the flange.

[0005] In view of this, the present invention provides a pipe flange processing device, comprising:

[0006] A cutting device is provided with a cutting edge, which is disposed on the flange end face and is used to perform cutting machining on the flange end face.

[0007] A fixing device is disposed inside the flange and connected to the cutting device. The fixing device is used to fix the cutting device to the flange.

[0008] In this technical solution, the cutting device is fixed to the flange by a fixing device, so that the cutting edge on the cutting device passes close to the flange end face, so that the cutting device can process the flange end face, thereby improving the processing efficiency of the flange.

[0009] Furthermore, the fixing device includes:

[0010] A fixing seat, which has openings at the top and bottom and has a hexagonal cross-section, is connected to a cutting device.

[0011] A support mechanism is detachably mounted on a fixed base. Multiple support mechanisms are provided, arranged circumferentially on the fixed base. One end of each support mechanism is fixedly connected to the inner circumferential surface of the flange.

[0012] In this technical solution, one end of multiple support mechanisms is supported within the inner circumferential surface of the flange, fixing the fixed seat at the circumferential center of the flange, thereby fixing the cutting device connected to the fixed seat onto the flange.

[0013] Furthermore, the support mechanism includes:

[0014] A connector is disposed on the outer surface of the fixed base in a direction perpendicular to the axis of the fixed base, and one end of the connector is threadedly connected to the fixed base by a bolt;

[0015] A telescopic cylinder, wherein the telescopic cylinder is fixedly mounted on the connecting member;

[0016] A telescopic rod is provided outside the fixing member along the extension direction of the connecting member, and one end of the telescopic rod is connected to the output end of the telescopic cylinder.

[0017] In this technical solution, the fixing seat is placed inside the flange, and the telescopic cylinder drives the telescopic rod to extend outward, so that one end of the telescopic rod contacts the inner circumferential surface of the flange. The telescopic rods on multiple support mechanisms support the flange, so that the fixing seat can be fixed inside the flange. After processing, the telescopic rod is retracted by the telescopic cylinder, thereby removing the fixing device from the flange for easy operation.

[0018] Furthermore, the fixed base is provided with a connecting base, the connecting base has a through connecting hole at its center, and the connecting base has a recessed fixing groove along the circumferential direction inside, and the connecting hole is axially fixedly connected to the cutting device.

[0019] Furthermore, the cutting device includes:

[0020] A positioning seat is disposed on the outside of the flange, and a cutting edge is rotatably provided on the positioning seat;

[0021] A moving mechanism is fixedly mounted on the side of the positioning seat, and the moving mechanism is used to drive the cutting edge to move;

[0022] A drive mechanism is disposed in a connecting hole and connected to a moving mechanism. The drive mechanism is used to drive the moving mechanism to move.

[0023] Furthermore, the drive mechanism includes:

[0024] A hollow motor, wherein the hollow motor is fixedly mounted on the connecting hole, and the lower end of the hollow motor is connected to the fixing groove;

[0025] A rotating shaft is disposed below the moving mechanism along the axis of the connecting hole. One end of the rotating shaft is connected to the output end of the hollow motor, and the other end of the rotating shaft is connected to the moving mechanism.

[0026] A rotating plate is mounted through a rotating shaft and is fixedly connected to the rotating shaft. A speed reducer is fixedly mounted on the rotating plate and is connected to a moving mechanism.

[0027] In this technical solution, the hollow motor starts working, driving the rotating shaft to rotate, which in turn drives the moving mechanism to rotate, allowing the cutting edge to rotate along the circumference of the flange. The reducer on the rotating plate is connected to the moving mechanism through a worm gear, allowing the cutting edge to slide on the flange end face, so that the cutting edge can be better machined on the flange end face.

[0028] Furthermore, a bearing is provided below the rotating plate, and the bearing is positioned above the connecting seat. The upper surface of the bearing is located on the same plane as the upper surface of the hollow motor, and the outer circumferential surface of the bearing is fixedly connected to the inner circumferential surface of the bottom of the rotating plate.

[0029] In this technical solution, the bearing can fix the position of the rotating plate and support the rotation of the rotating plate, reduce friction, and make the rotating shaft, rotating plate and bearing rotate together.

[0030] Furthermore, a first oil-free bushing is provided between the connecting seat and the bearing, and a second oil-free bushing is provided between the bearing and the rotating plate.

[0031] In this technical solution, the oil-free bushing uses a self-lubricating material, such as graphite filled in the metal material. The oil-free bushing can reduce friction under oil-free lubrication conditions, making the bearing rotate more smoothly and reducing the wear of the bearing during rotation.

[0032] Furthermore, the moving mechanism includes:

[0033] The outer casing is fixedly mounted on one side of the positioning seat;

[0034] The guide rail is slidably disposed below the housing and is slidably connected to the housing. The guide rail is also connected to the output end of the reducer.

[0035] In this technical solution, the housing sits on the guide rail and receives power from the gearbox through the worm gear to run the guide rail, so that the housing slides along the extension direction of the guide rail.

[0036] Furthermore, a gear set is provided below the outer casing, the gear set is fixedly connected to the rotating rod, the gear set is meshed with the reducer on the rotating plate, and a lifting cylinder is fixedly provided between the outer casing and the gear set.

[0037] In this technical solution, the reduction gearbox, which is fixedly connected to the rotating plate, is driven by meshing with the gear set. Under the movement of the lifting cylinder, the reducer meshes with different gears on the gear set, thereby adjusting the sliding speed of the housing to facilitate better machining of the flange end face.

[0038] The beneficial effects of this utility model are:

[0039] 1. In this utility model, the telescopic cylinder drives the telescopic rod to extend outward, so that one end of the telescopic rod contacts the inner circumferential surface of the flange. The telescopic rods on multiple support mechanisms are supported on the flange, so that the fixing seat can be fixed inside the flange. After processing, the telescopic cylinder retracts the telescopic rod, thereby removing the fixing device from the flange for easy operation.

[0040] 2. When the hollow motor in this utility model starts working, the hollow motor drives the rotating shaft to rotate, thereby driving the moving mechanism to rotate, so that the cutting edge can rotate along the circumference of the flange. The reducer on the rotating plate is connected to the moving mechanism through the worm gear, so that the cutting edge can slide on the flange end face, so that the cutting edge can be better processed on the flange end face.
