Detailed Description

In order to understand the technical solution more clearly, the technical solution is further described in detail below with reference to the accompanying drawings.

The fixture shown in fig. 1 includes a fixing frame 1, the fixing frame 1 has two side plates 1-1 arranged at an included angle as shown in fig. 2, in this embodiment, angle irons are used as the fixing frame 1 for practical use, a set of positioning plates 2 are arranged on the fixing frame 1 at intervals, the positioning plates 2 shown in fig. 2 are V-shaped and have the same included angle as the included angle of the side plates 1-1, so as to ensure that the height positions of the positioning plates 2 in the length direction of the fixing frame 1 are consistent, a set of position-adjustable clamping members 3 are further sleeved on the fixing frame 1, the clamping members 3 shown in fig. 4 can clamp and fix rods or pipes placed on the positioning plates 2, and since the height between the positioning plates 2 is determined, the rods or pipes fixed on the positioning plates 2 can be kept coaxial, and for convenient processing as shown in fig. 2, the positioning plates 2 can be made of angle irons.

In order to conveniently weld the fixing frame 1 with the hollow window 1-2, after one side of the bar or the pipe is welded, the clamp is turned over, the other side of the bar or the pipe is welded through the hollow window 1-2, the bar or the pipe is not required to be continuously welded after the clamping piece 3 is loosened to rotate, the bar or the pipe is prevented from being deformed by stress, and the flatness of the welded bar or pipe is ensured.

The clamping piece shown in fig. 3 comprises a fixing ring 3-1 sleeved on the positioning plate 2, a compression bolt 3-2 is connected to the fixing ring 3-1 in a threaded manner, and a bar or a pipe is compressed and fixed on the positioning plate 2 by screwing the compression bolt 3-2 to realize positioning and centering. For convenience in compression, the end part of the compression bolt 3-2 is movably provided with a V-shaped pressing block 3-3 which can be clamped on the periphery of a bar or a pipe, the V-shaped pressing block 3-3 can rotate relative to the compression bolt 3-2, and the V-shaped pressing block 3-3 can be kept not to rotate when the compression bolt 3-2 is screwed. In order to facilitate mounting and dismounting, the fixing ring 3-1 in the embodiment is divided into two sections, namely a lower fixing ring 3-11 and an upper fixing ring 3-12, and the upper fixing ring 3-12 and the lower fixing ring 3-11 are connected through a buckle to form a ring to be sleeved outside the fixing frame 1.

As shown in fig. 4, when positioning a rod or a pipe, the lengths of materials are different, so that the positioning plate 2 is movably arranged, the position is adjusted according to the length of the material, the alignment contact is kept outside the positioning plate 2 during positioning, welding of the rod or the pipe to the positioning plate 2 during welding is avoided, in addition, each section of the rod or the pipe needs to be at least provided with two positioning plates 2 for positioning and is at least pressed and fixed at the middle position through the clamping piece 3, or each section of the rod or the pipe is provided with three positioning plates 2 for supporting and positioning, and each corresponding positioning plate 2 is provided with one clamping piece 3 for pressing and fixing, the actual requirement is determined according to the length of the rod or the pipe, the shorter the better the rigidity is, the fewer the longer the rods or the pipe is provided with more positioning plates and clamping pieces, the better the positioning effect can be achieved, it can be seen from fig. 4 that three sections of rods or pipes can be arranged for centering once, and certainly the fixture needs to be determined according to the length of the rod or the pipe, so that the fixture is not only simple in structure, but also can simultaneously position and weld multiple sections of the rods or the pipes for positioning and the operation are convenient and fast for centering. It should also be noted that when the floor window is opened, in order to avoid the lack of rigidity of the side plate 1-1, the floor window may be opened in short and small positions, or several positions may be opened, or the positioning plate 2 is fixed on the fixing frame 1 to enhance the rigidity of the fixing frame 1, and certainly, the floor window is not necessarily opened, and the rod may be welded in all directions by rotating the rod or the pipe.
