Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing, in particular to a pipe fitting fixing mechanism for a milling machine. Background Art

[0002] Pipe fittings are a general term for components that play the role of connection, control, direction change, diversion, sealing, support, etc. in pipeline systems. Steel pipe fittings are all pressure-bearing pipe fittings. According to different processing techniques, they are divided into four categories, namely butt-welding pipe fittings, socket welding pipe fittings, threaded pipe fittings and flange pipe fittings.

[0003] During the production and processing of various types of pipe fittings, they need to be clamped and fixed. In the prior art, due to the different shapes and sizes of pipe fittings, a good clamping effect cannot be achieved for pipe fittings of any size. In addition, when fixing the existing pipe fittings, an adaptive position cannot be selected according to the actual length of the pipe fittings. During actual processing operations, the overall support force of the pipe fittings is insufficient, and the unprocessed parts may bend, which is not practical. Therefore, it is necessary to redesign a pipe fixing mechanism for a milling machine to address the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a pipe fixing mechanism for a milling machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, the limiting mechanism comprises a limiting rod fixedly installed inside the moving groove, and the limiting rod slides through the two moving blocks.

[0008] Preferably, the connection mechanism comprises a connection plate fixedly mounted on the end of the rotating shaft, and the end of the connection plate is fixedly connected to the inner wall of the connection plate.

[0009] Preferably, the lifting mechanism comprises an electric push rod fixedly mounted on the upper end surface of the lifting plate, and the telescopic end of the electric push rod is fixedly connected to the outer wall of the arc-shaped support plate.

[0010] Preferably, an anti-skid pad is fixedly installed on the inner wall of the arc-shaped clamping plate, and the anti-skid pad is made of rubber.

[0011] Preferably, the outer wall of the workbench is provided with a slide groove connected to the movable groove, and two storage boxes are slidably installed inside the slide groove.

[0012] Beneficial effects of the utility model:

[0013] 1. By setting up components such as cylinders, arc-shaped clamping plates and gears, under the telescopic effect of the cylinders, the two cylinders can drive the two arc-shaped clamping plates to move towards each other, thereby clamping and fixing pipes of different sizes. Under the cooperation of the two gears, the connecting plate is driven to rotate, and the connecting plate drives the clamped pipe to rotate, thereby realizing all-round processing of the pipe surface.

[0014] 2. By setting up components such as double-headed screws, moving blocks and support plates, when the double-headed screws rotate, they cooperate with the limit rods to drive the two moving blocks to move closer to each other, and the two moving blocks then drive the support plates and the lifting plates to move closer to each other, thereby achieving clamping and fixing of pipes of different lengths.

The connecting mechanism includes a connecting plate 9 fixedly installed on the end of the rotating shaft 8, and the end of the connecting plate 10 is fixedly connected to the inner wall of the connecting plate 9. Cylinders 11 are fixedly installed on the inner walls of the two connecting plates 10, and arc-shaped clamping plates 12 are fixedly installed on the telescopic ends of the two cylinders 11. Anti-skid pads 13 are fixedly installed on the inner walls of the arc-shaped clamping plates 12. The anti-skid pads 13 are made of rubber material, and the rubber material has good elasticity and softness, which enables it to form a closer contact between the surface and the object, thereby increasing friction and improving the friction coefficient.

[0022] A stabilizing plate 14 is fixedly mounted on the upper end surface of the support plate 6, a second motor 15 is fixedly mounted on the outer wall of the stabilizing plate 14, gears 16 are fixedly mounted on the outer wall of the rotating shaft 8 and the outer wall of the output shaft of the second motor 15, and the two gears 16 are meshed with each other, a lifting plate 17 is fixedly mounted on the end of the other moving block 5, an arc-shaped supporting plate 19 is fixedly mounted on the upper end surface of the lifting plate 17 through a lifting mechanism, the lifting mechanism includes an electric push rod 18 fixedly mounted on the upper end surface of the lifting plate 17, the telescopic end of the electric push rod 18 is fixedly connected to the outer wall of the arc-shaped supporting plate 19, a slide groove connected to the moving groove is opened on the outer wall of the workbench 1, and two storage boxes 20 are slidably mounted inside the slide groove.

[0023] When the utility model is used, when it is necessary to process the pipe fittings, the pipe fittings are first placed between the two arc-shaped clamping plates 12, and then the cylinder 11 can drive the two arc-shaped clamping plates 12 to move up and down, and clamp the pipe fittings while moving until they are fixed. Under the telescopic action of the two cylinders 11, pipe fittings of different sizes can be clamped and fixed, and at the same time, the friction between the pipe fittings and the anti-slip pad 13 can be increased to increase the clamping effect, and the first motor 3 is started, and the double-headed screw 2 is driven to rotate by the first motor 3. When the double-headed screw 2 rotates, it can drive the two moving blocks 5 to move relative to each other through the cooperation with the limit rod 4, and the two moving blocks 5 drive the support plate 6 and the lifting plate 17 to approach each other, thereby achieving the clamping and fixation of pipe fittings of different lengths.

[0024] At the same time, the electric push rod 18 drives the arc-shaped support plate 19 to move up and down, which can support the clamped and fixed pipe fittings and increase the stability of pipe fittings of different sizes during inspection. When it is necessary to process other parts of the pipe fittings, the second motor 15 is started. The second motor 15 drives one of the gears 16 to rotate and mesh with the gear 16 on the outer wall of the rotating shaft 8.
