Description

Technical Field

[0001] The utility model belongs to the technical field of pipe processing and relates to a clamping support tool, in particular to a support tool used for processing large-diameter thin-wall pipes. Background Art

[0002] Large-diameter thin-walled tubes are characterized by large diameter and thin wall. If the clamping force is too great during the clamping process of such workpieces, the workpiece will be deformed after processing, and an elliptical phenomenon will occur, resulting in waste. If the clamping force is insufficient, the workpiece will fall onto the lathe bed under the action of the cutting force, causing damage to the bed and tool holder, posing a safety hazard to the operator. Summary of the Invention

[0003] The purpose of the utility model is to provide a supporting tool for processing large-diameter thin-walled pipes, which has a scientific and reasonable structural design, reduces the scrap rate, avoids damage to the lathe, is safe and reliable, and is easy to implement.

[0004] The utility model solves the technical problem by the following technical solutions:

[0005] A supporting tool for processing large-diameter thin-walled tubes is characterized by comprising a cross-support frame, an adjusting screw and a fixing nut, wherein fixing nuts are provided at both ends of the cross-support frame, and the adjusting screw is threadedly installed on the fixing nut.

[0006] Moreover, the cross support frame is formed by welding seamless steel pipes.

[0007] Moreover, a rubber sleeve is packed at the nut of the adjusting screw.

[0008] The advantages and beneficial effects of the utility model are:

[0009] This supporting tooling used for processing large-diameter thin-walled pipes has the characteristics of small size, light weight, easy installation, firm clamping and good use effect.

[0010] This support fixture for machining large-diameter, thin-walled pipes improves both efficiency and economic benefits: Using this support allows for increased feed and depth during lathe machining, significantly improving efficiency. Furthermore, the finished pipe dimensions and roundness are guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely illustrative and non-restrictive, and should not be used to limit the scope of protection of the present invention.

[0016] A support fixture for processing large diameter thin-walled pipes, the innovation of which is that it includes a cross support frame 4, an adjusting screw 6 and a fixing nut 5. The ends of the cross support frame are provided with fixing nuts, and the adjusting screw is threadedly installed on the fixing nut. The cross support frame is welded by three seamless steel pipes, such as Figure 2 As shown, two shorter seamless steel pipes are vertically arranged on both sides of the middle of a longer seamless steel pipe, and the cross support frame forms four support positions on the inner wall of the large-diameter thin-walled wall.

[0017] The nut of the adjusting screw is packed with a rubber sleeve to ensure that the support fixture is stable on the inner wall of the large diameter thin-walled tube 3. Each adjusting screw is made of a grade 8.8 bolt and can be freely adjusted in length according to the inner diameter of the large diameter thin-walled tube.

[0018] Working principle:

[0019] Place this supporting fixture inside the large-diameter thin-walled tube, and locate it at the tube mounting end position, adjust the four adjusting screws at the end of the cross support frame, adjust the torque of the four adjusting screws with appropriate torque, and then match the large-diameter thin-walled tube to the clamping jaws of the four-jaw chuck 2. At this time, the clamping position 7 of the four-jaw chuck on the outer wall of the large-diameter thin-walled tube is consistent with the supporting position of the cross support frame on the inner wall of the large-diameter thin-walled tube. The internal support and external clamping method is adopted to ensure the firm clamping of the large-diameter thin-walled tube.

[0020] Working process:

[0021] 1. Select the cross support frame of corresponding length according to the diameter of the large diameter thin-walled tube;

[0022] 2. Install the cross support frame at the clamping position of the pipe end, and adjust the adjusting screw so that the nut of the adjusting screw abuts against the inner wall of the large-diameter thin-walled pipe;

[0023] 3. Use a four-jaw chuck for clamping, and the jaws of the four-jaw chuck correspond to the position of the adjusting screw;

[0024] 4. Start lathe 1 processing;

[0025] 5. After processing is completed, remove the supporting tooling.

[0026] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will understand that various replacements, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
