Description

Technical Field

[0001] This utility model belongs to the field of pig tail tube processing technology, and specifically relates to a multi-size rapid positioning device. Background Technology

[0002] The pig tail tube is an essential component in the converter. During use, the tube is subjected to high temperature and high pressure, which inevitably leads to thermal expansion and contraction. To prevent the pig tail tube from cracking due to thermal expansion and contraction, the tube must be bent into a certain shape.

[0003] However, dimensional control is relatively troublesome when bending pipes with a pipe bending machine. It can only be ensured by manually marking lines in advance, which has a certain impact on work efficiency and will also introduce errors during the marking process. Utility Model Content

[0004] The purpose of this invention is to provide a multi-size rapid positioning device that eliminates the need for multiple scribing operations, reduces scribing errors, and improves work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-size rapid positioning device, which is installed on a pipe bending machine for processing pig tail pipe fittings, comprising:

[0006] Fixture;

[0007] A lead screw, which is fixedly installed on the fixing frame;

[0008] Positioning blocks are spaced apart and sleeved on the lead screw. Each positioning block is locked to the lead screw on both sides by fixing nuts. At the same time, the positioning blocks can rotate around the lead screw so that the bottom of the positioning blocks rotates and abuts against the fixing frame.

[0009] Preferably, the fixing frame is an L-shaped plate structure, and both ends of the L-shaped plate also include integrally formed and welded fixing ear plates for installing the two ends of the lead screw.

[0010] Preferably, it also includes a bearing, the positioning block is sleeved with the lead screw through the bearing, and the two end faces of the bearing are stopped and limited by the fixing nut, so that the positioning block can slide and rotate along the lead screw.

[0011] Preferably, the positioning block includes a rotating arm and an abutment plate; the rotating arm and the abutment plate are integrally formed and connected, and the bearing is welded onto the rotating hole of the rotating arm.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] This invention replaces manual marking and bending with a multi-size positioning device, which ensures precise size control, eliminates the need to mark each pipe, reduces errors during marking, and improves work efficiency. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0018] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a multi-size rapid positioning device, installed on a pipe bending machine for processing pig tail pipe fittings, comprising:

[0019] Fixture 1;

[0020] Lead screw 2, which is fixedly installed on the fixing frame 1;

[0021] Positioning blocks 3 are spaced apart and sleeved on the lead screw 2. Each positioning block 3 is locked to the lead screw 2 on both sides by fixing nuts 4. At the same time, the positioning blocks 3 can rotate around the lead screw 2 so that the bottom of the positioning blocks 3 rotates and abuts against the fixing frame 1.

[0022] The fixing frame 1 is an L-shaped plate structure, and the two ends of the L-shaped plate also include integrally formed and welded fixing ear plates for installing the two ends of the lead screw 2.

[0023] It also includes a bearing, and the positioning block 3 is sleeved with the lead screw 2 through the bearing. The fixing nut 4 stops and limits the two ends of the bearing, so that the positioning block 3 can slide and rotate along the lead screw 2.

[0024] The positioning block 3 includes a rotating arm 31 and an abutment plate 32; the rotating arm 31 and the abutment plate 32 are integrally formed and connected, and the bearing is welded on the rotating hole of the rotating arm 31.

[0025] It also includes the following working principles:

[0026] The fixing nuts 4 are fixed to the lead screw 2 according to the required dimensions of the pigtail pipe to be bent. For example, four positioning blocks 3 are used to determine four dimensions; the number of positioning blocks 3 corresponds to the number of dimensions required. The positioning blocks 3 are welded to a bearing. After the two fixing nuts 4 fix the bearing to the lead screw 2, the positioning blocks 3 can rotate around the lead screw 2 via the bearing. The workpiece is placed on the fixing frame 1, pressing against the first positioning block 3 at the front end (away from the pipe bending machine) to determine the first dimension. The remaining positioning blocks 3 can rest on the workpiece. After the workpiece moves to the second dimension on the pipe bending machine side, the rotating positioning blocks 3 will automatically fall, allowing the workpiece to press against the second positioning block 3 to determine the second dimension. This process continues to determine subsequent dimensions. This device can be used on pipe bending machines and also in straight pipe multi-hole drilling machines.

[0027] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
