[0042] Example 1
[0043] like Figure 1-5 As shown, this embodiment of the utility model provides a positioning fixture for positioning the valve support 5, so that the valve support 5, the large stop valve 6, and the small stop valve 7 are pre-assembled. The positioning fixture includes:
[0044] Base plate 1;
[0045] A support assembly is disposed on the base plate 1 to support the valve bracket 5;
[0046] A limiting structure, constructed on the support assembly, is used to position the valve bracket 5.
[0047] In this embodiment, the positioning fixture includes: a base plate 1, a support component, and a limiting structure; the support component is disposed on the base plate 1 and is used to support the valve bracket 5; the limiting structure is disposed on the support component and is used to position the valve bracket 5. The positioning fixture in 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-assembled. Compared with operation on the production line, this embodiment uses the positioning fixture to pre-assemble the production in advance, which improves efficiency and can also avoid the quality hazards caused by materials falling and breaking during online production.
[0048] This embodiment solves quality problems such as low efficiency in line operation and product damage by introducing positioning fixtures. Pre-installation avoids quality problems caused by bumps and damage. The introduction of this gate valve screw pre-installation device reduces the number of staff by 1 person per shift, improves the efficiency of on-the-job operation, and solves the bottleneck process in production.
[0049] Multiple positioning fixtures can be used simultaneously to pre-install valve bracket 5, large gate valve 6, and small gate valve 7, allowing employees to operate in rotation, thereby further improving production efficiency.
[0050] The positioning fixture in this embodiment is universal and can be pre-installed on valve brackets 5 of 1P / 2P / 3P air conditioner outdoor units. During production, the valve brackets 5 are pre-installed on the production line. Pre-installation avoids damage to the valve brackets and shut-off valves caused by loose screws during assembly line tightening, preventing quality defects. Employees can also check the screw tightness to effectively identify faults and prevent defective products from being shipped out.
[0051] In some embodiments, the support assembly includes at least two support portions spaced apart on the base 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 portions spaced apart on the base plate 1, and a valve bracket 5 is disposed on top of the at least two support portions to support the valve bracket 5.
[0053] In some embodiments, the valve bracket 5 has a downwardly extending lug 51 at its bottom, and at least two support portions including a first support portion 21. The limiting structure is disposed on one side of the first support portion 21, and the lug 51 is limited between the first support portion 21 and the limiting structure.
[0054] Since the bottom of the valve bracket 5 has a downwardly extending lug 51, the at least two support parts in this embodiment include the first support part 21. By setting the limiting structure on one side of the first support part 21 and limiting the lug 51 between the first support 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 fixture.
[0055] In some embodiments, the limiting structure includes a first segment 31 and a second segment 32 connected together. The 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.
[0056] The limiting structure of this embodiment includes a first segment 31 and a second segment 32 connected together. By connecting the end of the first segment 31 away from the second segment 32 to the first support 21, and setting the second segment 32 at intervals from the first support 21, the hanging ear 51 is limited between the first support 21 and the limiting structure. The valve bracket 5 is positioned in this way to ensure that the valve bracket 5 is stably installed on the positioning fixture.
[0057] In some embodiments, the lug 51 is located at one end near the length of the valve bracket 5, and at least two support portions further include a second support portion 22; the second segment 32 is located on the side of the first support portion 21 away from the second support portion 22.
[0058] In this embodiment, the lug 51 is located at one end near the length of the valve bracket 5, and at least two support parts also include a second support part 22. In this embodiment, by setting the second segment 32 on the side of the first support part 21 away from the second support part 22, the first support part 21 and the second support part 22 can jointly support the valve bracket 5, while the lug 51 is limited between the first support part 21 and the limiting structure, thereby positioning the valve bracket 5 and ensuring that the valve bracket 5 is stably installed on the positioning fixture.
[0059] In some embodiments, the top of the second segment 32 is higher than the top of the first support 21, and the top of the second segment 32 gradually approaches the base plate 1 in the direction from the first support 21 toward the second support 22.
[0060] In this embodiment, the top of the second segment 32 is higher than the top of the first support 21. In the direction from the first support 21 to the second support 22, the top of the second segment 32 gradually approaches the bottom plate 1. This structure makes it easier for the hanging ear 51 to be limited between the first support 21 and the limiting structure, thereby improving assembly efficiency.
[0061] In some embodiments, the first support portion 21 and the second support portion 22 are at the same height and are located at opposite ends of the base plate 1 along its length.
[0062] In this embodiment, the first support part 21 and the second support part 22 are of equal height and are located at both ends near the length direction of the base plate 1, which can horizontally fix the valve bracket 5 on the positioning fixture, making it convenient to pre-assemble the valve bracket 5, the large stop valve 6 and the small stop valve 7, and improving the assembly efficiency.
[0063] In some embodiments, the bottom of the valve bracket 5 is also provided with a protrusion 52, which is located on the side of the lug 51 facing the first support portion 21. The first support portion 21 is provided with a slot 211, and the protrusion 52 is located in the slot 211.
[0064] In this embodiment, a slot 211 is provided on the first support part 21, and the protrusion 52 is set in the slot 211. Through cooperation with the limiting structure, the valve bracket 5 is further positioned to prevent the valve bracket 5 from moving back and forth or left and right on the positioning fixture.
[0065] In some embodiments, the top of the valve bracket 5 is configured with a first mounting position 55 and a second mounting position 56. One side of the valve bracket 5 is configured with two first mounting grooves 53 and second mounting grooves 54 that respectively penetrate the first mounting position 55 and the second mounting position 56. The large shut-off valve 6 is disposed at the first mounting position 55 and has a first tube 61 extending downward through the first mounting groove 53 and toward the second support portion 22. The small shut-off valve 7 is disposed at the second mounting position 56 and has a second tube 71 extending downward through the second mounting groove 54 and toward the second support portion 22. The second support portion 22 is provided with a clearance groove 221 to avoid the first tube 61 and the second tube 71.
[0066] In this embodiment, by providing a clearance groove 221 on the second support 22 to avoid the first pipe 61 and the second pipe 71, interference between the positioning fixture and the first pipe 61 of the large stop valve 6 and the second pipe 71 of the small stop valve 7 is prevented.
[0067] In some embodiments, the positioning fixture further includes a crossbeam 4, the two ends of which are connected to the first support portion 21 and the second support portion 22 respectively, thereby improving the stability of the positioning fixture.
[0068] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the devices, apparatuses, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here.
[0069] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
