[0036] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] like Figures 1-2 As shown, this utility model provides a pipe assembly tool for assembling pipes and fittings. The assembly tool includes a first clamping assembly 1, a second clamping assembly 2, and an adjusting assembly 3.

[0038] The first clamping assembly 1 is used to clamp the pipe, and the second clamping assembly 2 is used to clamp the pipe fitting;

[0039] The first clamping component 1 and the second clamping component 2 are connected by an adjusting component 3, which is used to adjust the position of the second clamping component 2 relative to the first clamping component 1.

[0040] The pipe is fixed in place by the first clamping component 1, and the pipe fitting is fixed in place by the second clamping component 2. After the pipe and fitting are fixed in place, the position of the second clamping component 2 relative to the first clamping component 1 is adjusted by the adjusting component 3, so that the end faces of the pipe and fitting that are close to each other are parallel and the pipe and fitting are aligned. After the fixing is completed, the workers are freed up and no manual assistance is required for subsequent welding and other operations. It can be used for clamping, fixing and aligning pipes and fittings of various specifications and sizes, with high adaptability and high practicality.

[0041] The angle and position can be finely adjusted by the adjustable component 3. The first clamping component 1 and the second clamping component 2 can clamp and fix pipes and fittings of various specifications and sizes, which greatly simplifies the assembly process. Compared with the traditional method, the assembly time can be shortened by more than 30%, significantly speeding up the construction progress and improving the assembly efficiency. Multi-directional displacement and rotation fine adjustment can be achieved with controllable accuracy down to the millimeter level.

[0042] Suitable for complex working conditions with different sizes and angles, the assembly tooling has a scientific structure that is easy to operate and adjust, greatly reducing the reliance on highly skilled workers. Frontline operators can quickly master the usage method, reducing human error and training costs.

[0043] According to one embodiment of the present invention, the first clamping assembly 1 includes a first support member and two first adjusting members;

[0044] Two first adjusting members are symmetrically arranged on both sides of the first support member, and the two first adjusting members cooperate to clamp the pipe.

[0045] According to one embodiment of the present invention, the first support member includes two symmetrically arranged arc-shaped plates 101;

[0046] The two arc plates 101 are connected by a plurality of second bolts 105.

[0047] Each arc plate 101 has a first through hole;

[0048] The first adjusting component includes a first adjusting bolt 102, a first adjusting nut 103, and a first clamping block 104;

[0049] The first adjusting nut 103 is fixed to the arc plate 101, and the first adjusting bolt 102 passes through the first adjusting nut 103 and the first through hole in sequence and is rotatably connected to the first clamping block 104.

[0050] A first cavity with openings at both ends is formed between the two arc-shaped plates 101. Part of the pipe is placed in the first cavity. By turning the first adjusting bolt 102, the distance between the two first clamping blocks 104 is adjusted, thereby fixing the pipe in place.

[0051] In actual use of pipe assembly fixtures, the top of the arc-shaped plate 101 has a fixing device that can fix the upper arc-shaped plate 101 in place, so that the first support member will not shake or shift. For example, the fixing device includes a frame, a cylinder, and an arc-shaped abutment plate. The first support frame is located on the frame, and the cylinder is connected to the top of the frame by a support rod. The arc-shaped abutment plate is installed on the pushing end of the cylinder. By pushing the cylinder, the arc-shaped abutment plate abuts against the upper arc-shaped plate 101 to prevent it from shaking. In addition, the fixing device can also support and limit the first support member for the base installed at the bottom of the bottom arc-shaped plate 101, preventing it from shaking or shifting.

[0052] Preferably, the first adjusting member further includes a limiting rod, which passes through the arc plate 101 and connects to the first pressing block 104. A first adjusting bolt 102 is provided. By turning the first adjusting bolt 102, the first pressing block 104 moves downward under the combined action of the first adjusting bolt 102 and the limiting rod. Its purpose has not deviated from the design concept of this utility model. Therefore, it should fall within the protection scope of this utility model.

[0053] Preferably, two first adjusting bolts 102 are connected to the same first pressing block 104. The two first adjusting bolts 102 have the same specifications and rotate at the same speed, so that the first pressing block 104 moves relative to the arc plate 101.

[0054] Optionally, only one first adjusting bolt 102 is connected to the same first clamping block 104. A T-slot is provided on the rectangular shell sidewall of the first clamping block 104. A first T-post is connected to the tail of the first adjusting bolt 102. A first rubber ring is provided between the first T-post and the sidewall of the T-slot. The first rubber ring is connected to the first T-post. Due to the first rubber ring, the friction between the first T-post and the T-slot can be increased, so that the first clamping block 104 will not rotate arbitrarily.

[0055] According to one embodiment of the present invention, the first pressing block 104 includes a first rectangular block and a first rubber block;

[0056] A first receiving groove is provided on the first rectangular block, and a first rubber block is embedded in the first receiving groove.

[0057] The first rubber block protrudes from the opening of the first receiving groove. The protruding surface of the first rubber block is arc-shaped, which provides better retention for the pipe.

[0058] According to one embodiment of the present invention, the second clamping assembly 2 includes a ring plate 201 and at least two second adjusting members;

[0059] Multiple second adjusting elements are arranged around the ring plate 201, and the multiple ring plates 201 cooperate to clamp the pipe fitting.

[0060] The second adjusting component is provided in four sets, and the four sets of second adjusting components are evenly spaced around the axis of the ring plate 201.

[0061] According to one embodiment of the present invention, the adjustment component 3 includes a first strip plate 301, a second strip plate 302, and a first fastener;

[0062] The first strip plate 301 is fixedly connected to the ring plate 201, and the second strip plate 302 is fixedly connected to the first support member;

[0063] The first fastener includes a first bolt 303, a first nut 304, and a second nut;

[0064] The first strip plate 301 has a first strip hole 305, and the second strip plate 302 has a second strip hole 306. The first bolt 303 passes through the second nut, the first strip hole 305 and the second strip hole 306 in sequence and is screwed to the first nut 304.

[0065] According to one embodiment of the present invention, the adjustment component 3 is provided in four sets. By providing four sets of adjustment components 3, the second adjustment component 3 can be fixed more stably, preventing the first set of adjustment components 3 from being subjected to excessive gravity, which could lead to rotation.

[0066] Because the pipe fittings have different specifications, that is, different sizes and curvatures, the position and angle of the second clamping component 2 relative to the first clamping component 1 can be adjusted by adjusting component 3, so as to better fix the pipe fittings and assemble them with the pipeline.

[0067] According to one embodiment of the present utility model, the second adjusting member includes a second adjusting bolt 202, a second adjusting nut 203 and a second pressing block 204. A plurality of second through holes are provided on the ring plate 201, and the second adjusting bolt 202, the second adjusting nut 203 and the second through holes correspond one-to-one.

[0068] The second adjusting nut 203 is fixedly connected to the ring plate 201;

[0069] The second adjusting bolt 202 passes through the second adjusting nut 203 and the second through hole in sequence and is then connected to the second clamping block 204.

[0070] The second clamping block 204 includes a second rectangular block and a second rubber block. The second rectangular block has a second receiving groove, and the second rubber block is embedded in the second receiving groove. The second rubber block protrudes from the opening of the second receiving groove, and the protruding surface of the second rubber block is an arc surface, which makes it easier to fix the pipe fitting.

[0071] In this embodiment, the second adjusting bolt 202 and the second clamping block 204 correspond one-to-one. The second adjusting bolt 202 and the second clamping block 204 are rotatably connected. The tail of the second adjusting bolt 202 is connected to a second T-shaped post. The second clamping block 204 is provided with a second T-shaped groove. The second T-shaped post is located in the second T-shaped groove. A second rubber ring is connected between the second T-shaped groove and the second T-shaped post. When the second adjusting bolt 202 is turned, the second clamping block 204 can rotate and move with the second adjusting bolt 202. During the adjustment process, the second clamping block 204 can be limited by holding it with one hand, so that it only performs translational movement when the second adjusting bolt 202 rotates.

[0072] Preferably, the axis of the first support member and the axis of the ring plate 201 are located in the same plane.

[0073] Furthermore, by using a measuring ruler, the adjustment distance of the first adjusting bolt 102 can be measured in real time, ensuring that the adjustment distances of the first adjusting bolts 102 located on both sides of the arc plate 101 are consistent. This ensures that after the pipe is fixed, the axis of the pipe coincides with the axis between the two arc plates 101. Multiple measuring rulers can be installed. The measuring ruler can also be installed on one side of the second adjusting bolt 202 to measure the distance of the second adjusting bolt 202. When the measuring ruler is installed on one side of the second adjusting bolt 202, its length and the direction of movement of the corresponding second adjusting bolt 202 are consistent.

[0074] In actual pipe assembly, the pipe assembly tooling also includes plate 106.

[0075] Specifically, the pipe is placed between the two first clamping blocks 104, and the first adjusting bolt 102 is tightened to fix the pipe in place. The end face of the fitting is fully aligned with the end face of the pipe (the axis of the fitting and the axis of the pipe are in the same plane). The fitting is located inside the ring plate 201. The second clamping assembly 2 is placed in a suitable position, and the worker assists in holding the fitting and the ring plate 201. The four second adjusting bolts 202 are tightened so that the corresponding second clamping blocks 204 work together to initially fix the fitting in place. Then, the second nut is pressed against one side of the first strip plate 301, and the first nut 30 is tightened. 4. Secure the ring plate 201 to fix the relative position of the pipe and fitting. Loosen the first adjusting bolt 102 on one of the arc-shaped plates 101 in the reverse direction, and move the pipe in the opposite direction to the fitting. Place a flat plate 106 at the end of the pipe near the fitting, with the plate 106 positioned between the pipe and fitting. Move the pipe towards the fitting end until the end of the fitting is in complete contact with the surface of the plate 106. After fixing, tighten the first adjusting bolt 102 and remove the plate 106. At this point, the end face of the fitting and the end face of the pipe are parallel, and the axis of the fitting and the axis of the pipe are in the same plane. A gap is left between the end face of the fitting and the end face of the pipe to allow for a weld. The size of the gap can be adjusted by replacing the plate 106 with one of different thicknesses. After fixing, subsequent welding operations can be performed without manual assistance.

[0076] Pipeline assembly tools can be quickly disassembled, transported, and maintained, thus allowing for flexible allocation according to the construction schedule and meeting the needs of multi-point parallel operations.
