[0044] Bottom plate 1;

[0045] A support assembly, disposed on the bottom plate 1, for supporting the valve bracket 5;

[0046] The limiting structure is constructed on the supporting assembly and is used to position the valve bracket 5.

[0047] In this embodiment, the positioning tooling includes: a base plate 1, a supporting assembly and a limiting structure; the supporting assembly is arranged on the base plate 1, and the supporting assembly is used to support the valve bracket 5; the limiting structure is arranged on the supporting assembly, and the limiting structure is used to position the valve bracket 5. The positioning tooling of this embodiment is used to position the valve bracket 5, so that the valve bracket 5, the large stop valve 6 and the small stop valve 7 are pre-installed. Compared with operating on the production line, this embodiment uses the positioning tooling to pre-install production in advance, thereby improving efficiency and avoiding quality risks caused by materials falling and breaking during online production.

[0048] This embodiment solves the quality problems such as low efficiency of line operation and damage to products by investing in positioning tooling, and pre-installs the parts in advance to avoid quality problems caused by bumps and damages. The investment in this stop valve screw pre-installation device achieves a reduction of one person per shift, improves job operation efficiency, and solves the bottleneck process in production.

[0049] A plurality of positioning fixtures can be used simultaneously to pre-install the valve bracket 5, the large stop valve 6 and the small stop valve 7, and employees can perform cycle operations to further improve production efficiency.

[0050] The positioning tool of this embodiment is universal and can be pre-installed on the valve bracket 5 of the 1P / 2P / 3P air conditioner outdoor unit. The valve bracket 5 is pre-installed in advance at the production line. Pre-installation can avoid the valve bracket and the stop valve from falling and causing quality failures due to tightening on the assembly line. Employees can check the tightening status of the screws, effectively discover faults, and avoid the flow of faulty products.

[0051] In some embodiments, the support assembly includes at least two support portions spaced apart from each other on the bottom plate 1 , and the valve bracket 5 is disposed on top of at least two of the support portions.

[0052] The support assembly of this embodiment includes at least two support parts spaced apart from each other on the bottom plate 1 , and the valve support 5 is provided on top of the at least two support parts, thereby supporting the valve support 5 .

[0053] In some embodiments, the bottom of the valve bracket 5 is configured with a downwardly extending ear 51, at least two support parts include a first support part 21, the limiting structure is arranged on one side of the first support part 21, and the ear 51 is limited between the first support part 21 and the limiting structure.

[0054] Since the bottom of the valve bracket 5 is constructed with a downwardly extending ear 51, the at least two supporting parts of this embodiment include a first supporting part 21. By setting a limiting structure on one side of the first supporting part 21 and limiting the ear 51 between the first supporting part 21 and the limiting structure, the valve bracket 5 is positioned to ensure that the valve bracket 5 is stably installed on the positioning tooling.

[0055] In some embodiments, the limiting structure includes a first segment 31 and a second segment 32 connected to each other, wherein one end of the first segment 31 away from the second segment 32 is connected to the first support portion 21 , and the second segment 32 is spaced apart from the first support portion 21 .
