Description

Technical Field

[0001] This utility model relates to the field of metal tube processing technology, and specifically to an angle adjustment device for metal tube processing. Background Technology

[0002] Metal pipes are generally classified into rectangular pipes and circular pipes according to their shape. Circular pipes are mainly used for fluid transportation. Because the cross-sectional shape of rectangular pipes is closer to that of a square or rectangle, they can more effectively resist deformation and torsion from external forces. They usually have higher strength and rigidity. Rectangular metal pipes are often used to manufacture various frames and structures. However, the welding process of this type of metal pipe still mainly adopts the method of manual fixing. Usually, the welder fixes one pipe to be welded to another by hand or foot and performs welding work while maintaining this manual fixing state. This manual fixing method is prone to causing the metal pipe to shift due to the welder's operation, affecting the welding quality. Moreover, this fixing method increases the difficulty of operation for the welder and is relatively inconvenient. Utility Model Content

Detailed Implementation

[0021] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0022] Example 1:

[0023] Reference Figures 1 to 4 This utility model provides an angle adjustment device for metal pipe processing, including a base 1 and a rotating frame 2. The rotating frame 2 is rotatably mounted on the base 1. A pressure block 3 for pressing the rotating frame 2 is movably arranged on the base 1. A tensioning component 4 for driving the pressure block 3 to move is arranged on the base 1. Fixing frames 5 are detachably arranged on both the base 1 and the rotating frame 2. Each fixing frame 5 is provided with a fastener 6 for fixing the pipe fitting 9 to be welded.

[0024] By installing fixing brackets 5 on the base 1 and the rotating frame 2 respectively, the fixing bracket 5 on the base 1, together with the fastener 6, fixes the base 1 to one of the pipe fittings 9 to be welded, and the fixing bracket 5 on the rotating frame 2, together with the fastener 6, fixes the other pipe fitting 9 to be welded. Rotating the rotating frame 2 can adjust the angle position of the two pipe fittings 9 to be welded. By using the tensioning component 4 to drive the pressure block 3 to press the rotating frame 2, the rotating frame 2 can be fixed. This realizes the angle adjustment work for metal pipe welding processing, eliminating the need for the welder to manually fix the pipe fittings 9 to be welded during the welding process, simplifying the welding operation and providing convenience for the welder. In addition, different specifications of fixing brackets 5 can be replaced on the base 1 and the rotating frame 2 as needed to be used for welding pipe fittings of different sizes and specifications, which has good versatility.

[0025] Specifically, the tensioning assembly 4 includes a handle 41 and a rotating rod 42. The rotating rod 42 is rotatably mounted on the base 1. The rotating frame 2 is provided with a central hole 21 through which the rotating rod 42 passes. The handle 41 is connected to the rotating rod 42. The rotating rod 42 is provided with a threaded part 421. The pressure block 3 is provided with a threaded hole 31 that mates with the threaded part 421.

[0026] Specifically, the pressure block 3 is a square block, and the base 1 is provided with a square groove for the pressure block 3 to be moved and installed. The square groove cooperates with the square block so that the square block can only move relative to the base 1 and cannot rotate relative to the base 1.

[0027] After fixing the two pipe fittings 9 to be welded on the two fixed brackets 5 respectively and adjusting the position of the rotating bracket 2, the rotating handle 41 drives the pressure block 3 to approach and press the rotating bracket 2 under the action of the threaded part 421 on the rotating rod 42 and the threaded hole 31 on the block, thus fixing the angular position between the two pipe fittings 9 to be welded. By rotating the handle 41 in the opposite direction, the pressure block 3 is driven away from the rotating bracket 2 and the pressing state on the rotating bracket 2 is released, so that the rotating bracket 2 can be swung freely to readjust the angular position between the two pipe fittings 9 to be welded.

[0028] Specifically, the side of the pressure block 3 that contacts the rotating frame 2 is provided with textures to increase friction.

[0029] By setting textures on the pressure block 3 to increase friction, the surface roughness of the pressure block 3 is increased to improve the friction between the pressure block 3 and the rotating frame 2, thereby improving the fastening effect on the rotating frame 2 and making the rotating frame 2 less prone to accidental deflection.

[0030] Example 2:

[0031] Reference Figures 1 to 4 In conjunction with the technical solution of Embodiment 1, in this embodiment, the fixing frame 5 includes a connecting plate 51, a limiting plate 52 and an adjusting plate 53. The connecting plate 51, the limiting plate 52 and the adjusting plate 53 are connected to each other to form a U-shaped frame structure with one end open. The fastener 6 is set on the adjusting plate 53 and is used to press the pipe fitting 9 to be welded against the connecting plate 51.

[0032] The pipe fitting 9 to be welded is moved into the opening and abuts against the limiting plate 52, and the pipe fitting 9 to be welded is pressed against the connecting plate 51 by the fastener 6, thus realizing the fixing operation of the pipe fitting 9 to be welded.

[0033] Specifically, the fastener 6 is a bolt, and the adjusting plate 53 is provided with an adjusting screw hole 531 that mates with the bolt thread. The bolt is used to fix the pipe fitting 9 to be welded onto the connecting plate 51.

[0034] By rotating the bolt, the bolt can be moved closer to or away from the connecting plate 51 under the action of the adjusting screw hole 531, thereby realizing the tightening and loosening operation of the pipe fitting 9 to be welded.

[0035] Specifically, the bolt is equipped with a handle 61.

[0036] By setting a handle 61 on the bolt, the welder can easily tighten the bolt manually to fasten the pipe fitting 9 to be welded.

[0037] Example 3:

[0038] Reference Figures 1 to 4 In conjunction with the technical solutions of Embodiment 1 and Embodiment 2, in this embodiment, both sides of the base 1 and both sides of the rotating frame 2 are provided with sliding grooves 7, both sides of the connecting plate 51 are provided with sliding protrusions 511 that are inserted and cooperate with the sliding grooves 7, and one end of the sliding groove 7 is provided with a limiting part 71 for the sliding protrusions 511 to abut.

[0039] By inserting and connecting the sliding protrusion 511 and the groove 7, the two fixing brackets 5 can be detachably installed on the base 1 and the rotating bracket 2 respectively through the connecting plate 51. This makes it easy to replace the fixing brackets 5 of different specifications as needed, so as to be suitable for different specifications of pipe fittings 9 to be welded, and has good versatility.

[0040] Specifically, mounting holes 72 are provided on both sides of the slide groove 7, and mounting screw holes 512 aligned with the mounting holes 72 are provided on both sides of the sliding protrusion 511. Each mounting screw hole 512 is threaded with a screw 8. The screw 8 passes through the mounting hole 72 and cooperates with the mounting screw hole 512 to fix the sliding protrusion 511 on the slide groove 7.

[0041] After the sliding protrusion 511 on the connecting plate 51 moves along the slide groove 7 to abut against the limiting part 71, the mounting screw hole 512 on the sliding protrusion 511 aligns with the mounting hole 72 on the slide groove 7. Then, the screw 8 is passed through the mounting hole 72 and threaded to the mounting screw hole 512 to achieve a detachable connection of the fixing bracket 5. The detachable installation of the fixing bracket 5 is achieved by using a threaded connection on the basis of the plug-in connection, which improves the tightness of the fixing bracket 5.

[0042] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model.
