Description

Technical Field

[0001] This utility model relates to the field of welded pipe mold technology, specifically a synchronous centering and positioning structure for welded pipe molds. Background Technology

[0002] Welded pipe molds are mainly used to produce various types of welded pipes. In the processing and production of welded pipe molds, since welded pipe molds are usually composed of multiple parts, these parts need to be connected by welding to form a complete mold. Before welding, the two parts of the mold need to be spliced ​​and fixed by a positioning structure so that welding can be carried out.

[0003] The announcement number is CN222095212U, which discloses "a positioning structure for a welding pipe mold processing device, including a welding machine body, wherein the welding machine body includes a machine body, a placement plate and a welding pipe mold";

[0004] There are still some drawbacks in its use. When clamping, the two mold sections are clamped directly, and the welded pipe needs to be manually pushed to connect them so that the welded ends of the two mold sections come into contact. After the mold is fixed, when the mold position needs to be adjusted, the clamping component needs to be separated from the mold before it can be adjusted. The mold position adjustment is inconvenient, and it is also inconvenient to adjust the mold connection angle after the mold is clamped, making it inconvenient to use. Utility Model Content

[0005] The purpose of this utility model is to provide a synchronous centering and positioning structure for welded pipe molds to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A synchronous centering and positioning structure for a welded pipe mold includes:

[0008] A base plate, on one side surface of which multiple mounting plates are fixedly installed;

[0009] Multiple fixing components are disposed on one side surface of the mounting plate. Each fixing component includes a base fixedly mounted on one side surface of the mounting plate. A first fixing ring is movably disposed on the inner side of the base. A second fixing ring is hinged to one end of the first fixing ring. A second slider is fixedly mounted on the outer surface of the first fixing ring. A spring is fixedly connected to one side surface of the second slider.

[0010] The clamping component is located inside the fixing component.

[0011] Furthermore, a semi-cylinder is fixedly installed at one end of the outer surface of both the first and second fixing rings, and a collar is movably sleeved on the outer side of the semi-cylinder.

[0012] Furthermore, the inner surface of the base is provided with multiple first-level sliding grooves, and the outer surface of the first-level fixing ring is symmetrically fixed with first-level sliders. The first-level sliders and second-level sliders are slidably connected to the first-level sliding grooves at their respective positions.

[0013] Preferably, the other end of the spring is fixedly connected to one end of the first groove at the corresponding position.

[0014] Furthermore, the clamping assembly includes:

[0015] Multiple slide rails are symmetrically fixedly installed on the inner surfaces of the first and second fixing rings;

[0016] Two clamps are movably located inside the first and second fixing rings;

[0017] Multiple slip rings are fixedly installed on the outer surfaces of the two clamping plates.

[0018] Preferably, the slip ring is slidably connected to the slide rail at the corresponding position, and multiple rubber strips are fixedly installed at equal intervals on the inner surface of the clamping plate.

[0019] Preferably, a second sliding groove is provided on the outer surface of the second fixing ring, a third slider is slidably connected inside the second sliding groove, a fastening knob is screwed onto the inner side of the third slider, and the fastening knob moves through the clamping plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. By placing the mold on the clamping plate inside the first fixing ring, gently push the first fixing ring outwards towards the docking point to compress the spring. Then close the second fixing ring to fix the mold with the two clamping plates. After releasing the first fixing ring, the spring force pushes the second slider to slide inside the first slide groove, moving the mold towards the docking point. Thus, the spring force gives the mold a moving force, pushing the two molds to dock autonomously. At the same time, the spring's contraction range makes it easy to adjust the mold's splicing position, making it easier to use.

[0022] 2. Through the sliding connection of the slip ring and the slide rail, the clamping plate can drive the mold to rotate, which makes it easy to adjust the angle of the mold after clamping, thereby adjusting the angle of the welding surface of the mold and making the mold easier to weld. Turning the fastening knob, one end of which passes through the clamping plate and abuts against the mold, allows the clamping assembly to clamp molds of different diameters, increasing the clamping range of the clamping assembly.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 In this embodiment of the utility model, a synchronous centering and positioning structure for a welded pipe mold includes a base plate 1. Multiple mounting plates 101 are fixedly installed on one side surface of the base plate 1. Multiple fixing components 2 are disposed on one side surface of the mounting plates 101. The fixing components 2 include a base 201 fixedly installed on one side surface of the mounting plates 101. A first fixing ring 203 is movably disposed on the inner side of the base 201. A second fixing ring 207 is hinged to one end of the first fixing ring 203. A second slider 205 is fixedly installed on the outer surface of the first fixing ring 203. A spring 206 is fixedly connected to one side surface of the second slider 205. A clamping component 3 is disposed on the inner side of the fixing component 2.

[0031] Specifically, multiple mounting plates 101 are used to install the fixing component 2. The fixing component 2 limits the position of the mold, so that one of the two molds moves towards the middle to dock. Then, the mold is fixed by the clamping component 3, and the mold can be rotated at a certain angle to facilitate welding at the docking point.

[0032] Example 1

[0033] like Figure 2 and Figure 5 As shown, in this embodiment, a semi-cylinder 208 is fixedly installed at one end of the outer surface of both the first fixing ring 203 and the second fixing ring 207. A collar 209 is movably sleeved on the outer side of the semi-cylinder 208. When the second fixing ring 207 and the first fixing ring 203 are closed, the two semi-cylinders 208 form a cylinder. The collar 209 is moved so that it covers the two semi-cylinders 208, quickly fixing the second fixing ring 207 and the first fixing ring 203. Multiple first sliding grooves 202 are opened on the inner surface of the base 201. A first slider 204 is symmetrically fixedly installed on the outer surface of the first fixing ring 203. The first slider 204 and the second slider 205 are slidably connected to the first sliding groove 202 at the corresponding positions. The other end of the spring 206 is fixedly connected to one end of the first sliding groove 202 at the corresponding position.

[0034] In this embodiment, the mold is placed above the clamping plate 302 inside the first fixing ring 203. The first fixing ring 203 is gently pushed outward from the docking point, causing the spring 206 to be in a contracted state. Then, the second fixing ring 207 is closed, so that the two clamping plates 302 clamp and fix the mold. After the first fixing ring 203 is released, the elastic force of the spring 206 pushes the second slider 205 to slide inside the first slide groove 202, driving the mold to move towards the docking point. Thus, the elastic force of the spring 206 gives the mold a moving force, pushing the two molds to dock autonomously. At the same time, the contraction range of the spring 206 makes it easy to adjust the splicing position of the mold, making it easier to use.

[0035] like Figure 2-4 As shown, in this embodiment, the clamping assembly 3 includes: multiple slide rails 301 symmetrically fixedly installed on the inner surfaces of the first fixing ring 203 and the second fixing ring 207; two clamping plates 302 movably disposed inside the first fixing ring 203 and the second fixing ring 207; and multiple slide rings 303 respectively fixedly installed on the outer surfaces of the two clamping plates 302; the slide rings 303 are slidably connected to the slide rails 301 at corresponding positions; and multiple rubber strips 306 are fixedly installed at equal intervals on the inner surfaces of the clamping plates 302.

[0036] In practice, multiple rubber strips 306 increase the friction between the clamping plate 302 and the mold when the mold is clamped, making the clamping more secure. Then, through the sliding connection of the slip ring 303 and the slide rail 301, the clamping plate 302 can drive the mold to rotate, which makes it easier to adjust the angle of the mold after clamping, thereby adjusting the angle of the welding surface of the mold and making the mold easier to weld.

[0037] Example 2

[0038] Based on Embodiment 1, in order to overcome the problem that the clamping component 3 is not convenient for fixing molds of different diameters.

[0039] like Figure 5 As shown, in this embodiment, a second groove 307 is provided on the outer surface of the second fixing ring 207, a third slider 304 is slidably connected inside the second groove 307, a fastening knob 305 is screwed onto the inner side of the third slider 304, and the fastening knob 305 moves through the clamping plate 302.

[0040] In practice, the fastening knob 305 is turned, and one end of it passes through the clamping plate 302 and abuts against the mold, so that the clamping component 3 can clamp molds of different diameters, thereby increasing the clamping range of the clamping component 3.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
