Description

Technical Field

[0001] This utility model belongs to the field of steel processing technology, and specifically relates to a tool that facilitates multi-angle processing. Background Technology

[0002] During production operations, workers often need to process materials temporarily. Some materials require specific angles for processing. In traditional steel pipe processing, workers typically use manual marking or simple clamps to achieve this angle processing. However, manual marking relies on visual alignment, which is prone to errors and has low repeatability, making it unsuitable for batch processing. Simple clamps require multiple adjustments to bolt tightness to fix the angle, which is cumbersome and time-consuming. Furthermore, the clamps have poor stability, and vibrations during welding can easily cause angle shifts. Utility Model Content

[0003] The purpose of this invention is to provide a tool that facilitates multi-angle processing, aiming to solve the problems of low accuracy and efficiency of manual measurement, insufficient stability of fixtures, and easy pipe shaking and processing failure caused by single-person operation in the aforementioned background technology.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A tool for facilitating multi-angle machining includes bearings, two of which are arranged vertically. An inner steel tube is sleeved between the inner rings of the two bearings. The inner ring of the inner steel tube has scale markings. The outer rings of the two bearings are respectively sleeved with outer steel tubes. A gap is provided between the upper and lower outer steel tubes. The two outer steel tubes are respectively connected to a fixing device. A gap is provided between the fixing device and the outer steel tube.

[0005] Furthermore, the fixing device includes iron plate bases respectively set on two outer steel pipes. An inner threaded tube is fixed to the surface of the iron plate base at the end away from the outer steel pipe. A bolt is inserted through the inner threaded tube. An inner nut is provided at the end of the bolt near the bearing, and an outer nut is provided at the other end.

[0006] The beneficial effects of this utility model are as follows: By connecting the inner and outer steel pipes with upper and lower bearings, and with the 0-360° engraving marks on the inner steel pipe, stepless adjustment and precise reading of the angle can be achieved (accuracy can reach ±1°); the gap between the upper and lower outer steel pipes prevents friction when the bearings rotate; the quick fixing mechanism adopts a three-point clamping structure of bolt-nut-iron plate base, which can be completed by a single person; the lightweight design adopts a combination of steel pipe and bearing, which is easy to carry to the field and solves the problems of traditional clamps being bulky and difficult to move.

[0009] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0010] Example 1 like Figures 1 to 2 As shown, a tool for facilitating multi-angle machining includes bearings 2, two of which are arranged vertically. An inner steel tube 1 is sleeved between the inner rings of the two bearings 2. The height of the inner steel tube 1 is set to 10cm, and its upper and lower ends are flush with the upper and lower bearings 2. The inner ring of the inner steel tube 1 is marked with a 0-360° scale. The outer rings of the two bearings 2 are respectively sleeved with outer steel tubes 3. The height of the outer steel tubes 3 is set to 4-5cm. There is a gap between the upper and lower outer steel tubes 3 so that no friction is generated when the bearings 2 rotate. The two outer steel tubes 3 are respectively connected to a fixing device, and there is a gap between the fixing device and the outer steel tube 3.

[0011] Specifically, the fixing device includes iron plate bases 4 respectively set on two outer steel pipes 3. The surface of the iron plate bases 4 away from the outer steel pipes 3 is fixed with an inner thread tube 5. A bolt 6 is installed through the inner thread tube 5. The height of the bolt 6 is the midpoint of the height of the inner steel pipe 1. An inner nut 7 is provided at the end of the bolt 6 near the bearing 2, and an outer nut 8 is provided at the other end to facilitate the operator to tighten the bolt 6.

[0012] In practical applications, taking two steel pipes to be processed as an example, align the fixing device at one end of the device with one of the steel pipes to be processed, place the steel pipe to be processed in the gap between the inner nut 7 and the outer steel pipe 3, rotate the outer nut 8 at this end to push the bolt 6 inward until the steel pipe to be processed is clamped between the inner nut 7 and the outer steel pipe 3, ensuring that the axis of the steel pipe to be processed is perpendicular to the central axis of the outer steel pipe 3.

[0013] Then, using the inner steel tube 1 of the tool as the rotation axis, observe the 0-360° markings on the inner side of the inner steel tube 1 according to the processing requirements, and rotate the outer steel tube 3 at the other end to make it rotate the fixing device at the other end until it aligns with the target angle scale line. Place the second steel tube to be processed into the fixing device after adjusting the angle, following the above steps, ensuring that the welding ends of the two steel tubes to be processed are in close contact and the angle error does not exceed ±1°. Keep the tool fixed and weld the connection between the two pipes; during the welding process, the inner rings of the upper and lower bearings 2 are fixed to the inner steel tube 1, and the outer rings keep the angle stable synchronously with the outer steel tube 3, and the angle will not shift due to welding stress. Depending on the specifications of the product to be tested, steel tubes with diameters of 50-200mm can be processed by changing the bolts 6 and iron plate bases 4 of different specifications.
