Description

Technical Field

[0001] This utility model relates to the field of air conditioning refrigeration system installation technology, and in particular to welding fixtures for air conditioning copper pipes. Background Technology

[0002] In air conditioning systems, due to the large number of pipes, copper pipes tend to sag under gravity after the pipes are installed. This makes it difficult to maintain balance and verticality during welding, which affects the welding of joints. Traditionally, one person holds the copper pipe while another welds it. However, this often results in the arm accidentally touching the welded joint and being burned by the uncooled weld. Furthermore, the shaking caused by the person can affect the quality of the weld.

[0003] Existing technologies have the following problems:

[0004] Traditional welding fixtures typically consist of a single lifting bracket, capable of supporting only a single copper pipe at a time. When dealing with multiple copper pipes densely arranged in an air conditioning system, this necessitates frequent adjustments to the fixture position or the use of multiple sets of fixtures in parallel, resulting in severely low welding efficiency. For example, the air conditioning copper pipe welding support fixture disclosed in application number CN201820399478.X significantly increases welding time in the case of welding pipes in large central air conditioning units due to the single-pipe support method. Secondly, existing fixtures often have fixed lifting brackets, which cannot be flexibly adjusted according to the spacing and height of the copper pipes. When encountering different models of air conditioning units or special pipe layouts, traditional fixtures often need to be customized due to their incompatibility, increasing production and time costs. Furthermore, some welding fixtures use an integrated design between the lifting bracket and the main structure. Once the bracket component is damaged, the entire fixture needs to be replaced, resulting in high maintenance costs. For instance, after the lifting bracket placement slot wears down over time, the entire support assembly must be replaced, leading to persistently high maintenance costs for the fixture.

[0005] To address these shortcomings, we proposed a welding fixture for air conditioning copper pipes. Utility Model Content

[0006] The purpose of this utility model is to propose a welding fixture for air conditioning copper pipes to overcome the shortcomings of existing technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an air conditioning copper pipe welding fixture, including a base, a column rotatably connected to the top surface of the base, a sliding seat slidably connected to the outer wall of the column, and a lifting bracket detachably installed on one side of the sliding seat. The inner wall of the sliding seat is provided with a receiving groove, and a fastening block is provided inside the receiving groove. One side surface of the fastening block abuts against the outer wall of the column. A hand-tightening bolt is threadedly connected to the surface of the sliding seat, and one end of the hand-tightening bolt extends into the receiving groove and is fixedly connected to the side surface of the fastening block away from the column.

[0008] The sliding seat has a slot on its surface, one end of the lifting bracket is inserted into the slot, the sliding seat has a locking hole on its surface, and the lifting bracket has a clearance groove on its surface corresponding to the locking hole. The clearance groove is connected to a locking block by a spring, and the locking block is used in conjunction with the locking hole.

[0009] The lifting support is provided in multiple ways, and the multiple lifting supports are arranged along the axial direction of the column.

[0010] The surface of the lifting bracket is provided with a copper tube placement groove, and a protective pad is adhered inside the copper tube placement groove.

[0011] The surface of the sliding seat is provided with a through hole that is slidably connected to the column.

[0012] The volume of the clearance groove is larger than the volume of the locking block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, multiple independently adjustable lifting supports are set on the same column, which can support and position multiple copper pipes at one time. For example, when supporting three parallel copper pipes, it can reduce the position adjustment by two times compared with the traditional single support tooling, and the welding efficiency is significantly improved. Each lifting support can be independently adjusted in height to adapt to copper pipes with different diameters and arrangement heights, ensuring the uniformity and stability of multi-pipe support.

[0015] This invention features a detachable modular lifting bracket, which allows for flexible adjustment of the support span and number of supports based on the spacing between copper pipes. This reduces deployment time compared to traditional fixed fixtures and makes maintenance and replacement much easier. Attached Figure Description

[0025] Please refer to Figure 1 and Figure 2 The air conditioning copper pipe welding fixture includes a base 1, a column 2 rotatably connected to the top surface of the base 1, a sliding seat 3 slidably connected to the outer wall of the column 2, and a lifting bracket 8 detachably installed on one side of the sliding seat 3.

[0026] The base 1 serves as the basic support component of the tooling and is connected to the column 2 via a rotatable connection, allowing for angle adjustment of the column 2 to accommodate copper pipe welding requirements in different orientations. The column 2 is set perpendicular to the base 1, providing a vertical sliding track for the sliding seat 3. Its outer wall mates with the through hole of the sliding seat 3, ensuring that the sliding seat 3 can move up and down along the column 2. The sliding seat 3 is fitted onto the outer wall of the column 2, and its height on the column 2 can be adjusted by sliding. A detachable lifting bracket 8 is provided on one side for installing components that support the copper pipe.

[0027] The inner wall of the sliding seat 3 is provided with a receiving groove 4, and a fastening block 6 is provided inside the receiving groove 4. One side surface of the fastening block 6 abuts against the outer wall of the column 2. The surface of the sliding seat 3 is threaded with a hand-tightening bolt 5, and one end of the hand-tightening bolt 5 extends into the receiving groove 4 and is fixedly connected to the side surface of the fastening block 6 away from the column 2.

[0028] The receiving groove 4 is located on the inner wall of the sliding seat 3. The fastening block 6 is set in the groove, and one side of it directly contacts the outer wall of the column 2. The hand-tightening bolt 5 is connected to the surface of the sliding seat 3 through the thread. When the hand-tightening bolt 5 is tightened, the bolt pushes the fastening block 6 to move towards the column 2. The friction between the fastening block 6 and the outer wall of the column 2 is used to lock the height of the sliding seat 3, so as to achieve quick adjustment and fixation.

[0029] Please refer to Figure 1 , Figure 3 and Figure 4 The surface of the sliding seat 3 is provided with a slot 7, one end of the lifting bracket 8 is inserted into the slot 7, the surface of the sliding seat 3 is provided with a locking hole 12, the surface of the lifting bracket 8 is provided with a clearance groove 10 corresponding to the position of the locking hole 12, and the interior of the clearance groove 10 is connected to a locking block 13 by a spring 11, and the locking block 13 is used in conjunction with the locking hole 12.

[0030] The slot 7 on the surface of the sliding seat 3 is used to insert one end of the lifting bracket 8 to form a preliminary positioning. The locking mechanism (locking hole 12, clearance groove 10, spring 11, locking block 13) is used to quickly lock the lifting bracket 8 when it is inserted into the slot 7. The clearance groove 10 on the lifting bracket 8 is aligned with the locking hole 12 of the sliding seat 3. The spring 11 pushes the locking block 13 to pop out and embed into the locking hole 12, thereby achieving quick locking of the lifting bracket 8. When disassembling, press the locking block 13 to retract it into the clearance groove 10, and the lifting bracket 8 can be pulled out for easy replacement or adjustment of the bracket position.

[0031] Please refer to Figure 1 and Figure 2 Multiple lifting supports 8 are provided, and the multiple lifting supports 8 are arranged along the axis of the column 2.

[0032] Multiple lifting supports 8 can be arranged vertically along the column 2 to simultaneously support multiple copper pipes of different heights, solving the problem of needing to adjust multiple times with a traditional single support and improving welding efficiency.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 The surface of the lifting bracket 8 is provided with a copper tube placement groove 9, and a protective pad is adhered inside the copper tube placement groove 9.

[0034] The copper tube placement groove 9 is used to support the copper tube. The shape of the groove is adapted to the outer diameter of the copper tube to ensure stable support. The protective pad is adhered to the inside of the copper tube placement groove 9. The material is usually rubber or soft material, which can prevent scratches on the surface of the copper tube and increase friction to prevent the copper tube from sliding during welding.

[0035] Please refer to Figure 1 and Figure 3 The surface of the sliding seat 3 is provided with a through hole that is slidably connected to the column 2.

[0036] The diameter of the through hole is slightly larger than the outer diameter of the column 2 to ensure that the sliding seat 3 can slide smoothly up and down along the column 2, while ensuring stability during sliding.

[0037] Please refer to Figure 1 and Figure 4 The volume of the clearance slot 10 is greater than the volume of the locking block 13.

[0038] The space of the clearance groove 10 is larger than that of the locking block 13, providing room for the extension and retraction of the locking block 13 under the action of the spring 11, preventing the locking block 13 from getting stuck, and ensuring smooth disassembly and installation of the lifting bracket 8.

[0039] Working principle: In use, first fix the base 1 to the metal chassis of the air conditioning unit. Then, according to the arrangement height of the copper pipes, slide the sliding seat 3 up and down along the column 2. After adjusting to the appropriate position, tighten the hand-tightening bolt 5 and push the fastening block 6 to press against the outer wall of the column 2 to lock the height of the sliding seat 3. Next, according to the number and spacing of the copper pipes, insert the lifting bracket 8 into the slots 7 of multiple sliding seats 3. When inserted, the locking block 13 of the lifting bracket 8 automatically engages with the locking hole 12 of the sliding seat 3 under the action of the spring 11, completing the bracket fixing. If it is necessary to adjust the number or position of the brackets, press the locking block 13 to retract it, and the bracket can be disassembled. Finally, place multiple copper pipes into the copper pipe placement slots 9 of each lifting bracket 8. The protective pad can prevent the copper pipes from sliding and scratching. Since multiple lifting brackets 8 can be independently adjusted in height along the column 2, they can adapt to copper pipes of different heights and achieve one-time synchronous support, avoiding safety hazards and welding quality problems caused by manual pipe support. After welding is completed, the tooling can be disassembled by reversing the operation, which is convenient for storage and next use.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
