Description

Technical Field

[0001] This utility model relates to the field of fiberglass product assembly technology, specifically to a positioning fixture for assembling the center distance of positioning columns. Background Technology

[0002] In the stacking process of fiberglass composite products, positioning posts play a crucial role. They provide precise positioning benchmarks, prevent component displacement, ensure repeatability during assembly, enhance structural integrity, and support standardized design. The deviation in the center distance of the positioning posts determines the stability and reliability of the product during actual use.

[0003] Currently, the assembly of positioning posts mostly adopts traditional processes. First, the center distance between two positioning posts is determined manually using vernier calipers, and then the positioning posts are fixed. This operation method is prone to the following problems:

[0004] First, human visual observation has visual biases, making it difficult to achieve accurate positioning. At the same time, the uneven assembly skills among operators can easily introduce random errors, resulting in poor consistency between product batches.

[0005] Second, the positioning process is complex and cumbersome, which seriously affects assembly efficiency and is a bottleneck process in the assembly process, thus restricting the product production progress. Summary of the Invention

[0006] This invention addresses the problem that traditional assembly processes easily introduce random errors, leading to poor consistency between product batches and slow assembly efficiency. It provides a positioning fixture for assembling the center distance of positioning columns. This fixture is easy and quick to operate, has high positioning accuracy, reduces random errors, improves assembly efficiency and assembly pass rate, meets the requirements for consistency between product batches, and has significant engineering application value.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A positioning fixture for assembling the center distance of positioning posts, wherein there are at least two positioning posts arranged in parallel, and the distance between the centers of two positioning posts is the center distance of the positioning posts. The positioning fixture includes a connecting sleeve and a connecting rod, wherein one end of the connecting sleeve is matched with the positioning post and the other end is provided with the connecting rod.

[0009] The connecting sleeve and the positioning post are fitted with a clearance. The positioning post includes a rod, a protrusion and a head from bottom to top. The width of the protrusion is greater than the width of the head, and the width of the head is greater than the width of the rod.

[0010] The bottom of the connecting sleeve is provided with a positioning groove, which mates with the column head. At least two connecting sleeves are provided on the connecting rod. The direct mating of the connecting sleeves with the positioning column enables rapid positioning of the positioning column.

[0011] Furthermore, the upper part of the column head is conical and the lower part is cylindrical, the protrusion is hexagonal prism, and the column rod is cylindrical. The column head, protrusion, and column rod are concentrically arranged. High-precision control of the center distance of the positioning column is achieved by controlling the center distance of the connecting sleeve.

[0012] Furthermore, the connecting sleeve is concentrically cylindrical, with the upper diameter of the connecting sleeve being smaller than the lower diameter. The positioning groove has a convex cross-section, with the upper notch of the positioning groove matching the column head and the lower notch matching the protrusion. The positioning groove is used to connect to and engage with the positioning column.

[0013] Furthermore, the positioning groove is cylindrical, and the gap between the positioning groove and the column head is less than 0.16 mm. The smaller the gap, the higher the positioning accuracy.

[0014] Furthermore, the connecting rod includes a set of connecting plates connected in parallel between the connecting sleeves, and a plurality of reinforcing columns disposed between the connecting plates, the direction of which is parallel to the connecting sleeves. The reinforcing columns are used to improve its resistance to deformation and increase its service life.

[0015] Furthermore, the connecting rod is strip-shaped, with a connecting sleeve at each end. The center distance between the connecting sleeves is the same as the center distance between the positioning posts required by the process.

[0016] Furthermore, the bottom outer periphery of the column is provided with external threads. The external threads are used to connect to the bottom housing.

[0017] The beneficial effects of this utility model through the above technical solution are as follows:

[0018] Eliminating random errors and ensuring product standardization. This utility model achieves high-precision positioning of the center distance of the positioning columns through dimensional chain control, eliminating random errors caused by human operation, improving product consistency, ensuring product standardization, achieving a 100% assembly qualification rate, and guaranteeing the alignment accuracy of internal components; it also has strong scalability, is compatible with similar structural products, and reduces tooling development costs.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] like Figures 1-3 As shown, this embodiment provides a positioning fixture for assembling the center distance of positioning posts. There are at least two positioning posts 1, which are arranged in parallel. The distance between the centers of the two positioning posts is the center distance of the positioning posts. The positioning fixture is used to adjust the positioning posts 1 to ensure that the center distance of the positioning posts 1 meets the production process requirements.

[0026] The positioning fixture includes a connecting sleeve 2 and a connecting rod 3. One end of the connecting sleeve 2 is matched with the positioning post 1, and the other end is provided with the connecting rod 3. At least two connecting sleeves 2 are provided on the connecting rod 3. The connecting sleeve 2 and the connecting rod 3 can be made of any one of carbon structural steel, high-quality low-carbon alloy steel, aluminum alloy, or stainless steel. The connecting rod 3, the connecting sleeve 2, and the reinforcing post 4 are all connected by welding.

[0027] The bottom of the connecting sleeve 2 is provided with a positioning groove, which cooperates with the column head 101. The connecting sleeve 2 and the positioning column 1 are fitted with a clearance fit. Specifically, the connecting sleeve 2 and the column head 101 of the positioning column 1 are fitted with an H7 / g6 clearance fit.

[0028] As one possible implementation method, such as Figure 2 As shown, the positioning post 1 includes, from bottom to top, a post rod 103, a protrusion 102, and a post head 101. The width of the protrusion 102 is greater than the width of the post head 101, and the width of the post head 101 is greater than the width of the post rod 103.

[0029] Specifically, the upper part of the column head 101 is conical and the lower part is cylindrical, the protrusion 102 is hexagonal prism, and the column rod 103 is cylindrical. The column head 101, the protrusion 102, and the column rod 103 are concentrically arranged. The height of the column head 101 is greater than the height of the protrusion 102.

[0030] The bottom outer periphery of the column rod 103 is provided with external threads to facilitate the connection between the positioning column 1 and the box body.

[0031] As one possible implementation method, such as Figure 3 As shown, the connecting sleeve 2 is a concentric cylinder, the diameter of the upper part of the connecting sleeve 2 is smaller than the diameter of the lower part, the cross-section of the positioning groove is convex, the upper notch of the positioning groove matches the column head 101, and the lower notch of the positioning groove matches the protrusion 102.

[0032] Specifically, the upper inner diameter of the positioning groove is smaller than the lower inner diameter of the positioning groove, the height of the upper notch of the positioning groove is greater than the height of the column head 101, the height of the lower notch of the positioning groove is greater than the height of the protrusion 102 and less than the height of the column head 101, and both the upper and lower parts of the positioning groove are cylindrical.

[0033] To ensure positioning accuracy, the positioning groove is cylindrical, and the gap between the positioning groove and the column head 101 is less than 0.16mm. The smaller the gap between the connecting sleeve 2 and the column head 101 of the positioning column 1 (i.e., the smaller the difference between the upper inner diameter of the connecting sleeve 2 and the diameter of the column head 101 of the positioning column 1), the smaller the eccentricity between the positioning column 1 and the connecting sleeve 2, and the higher the center distance accuracy of the positioning column. Preferably, the gap between the positioning groove and the positioning column 1 is 0.06mm, ensuring positioning accuracy without affecting positioning efficiency.

[0034] The connecting rod 3 is used to connect and fix the connecting sleeve 2. In one possible implementation, the connecting rod 3 includes a set of connecting plates parallel to each other between the connecting sleeves 2, and a plurality of reinforcing columns 4 disposed between the connecting plates. The direction of the reinforcing columns 4 is parallel to that of the connecting sleeve 2. The connecting rod 3, the connecting sleeve 2, and the reinforcing columns 4 are all welded together. The reinforcing columns 4 are used to improve their resistance to deformation and increase their service life.

[0035] Specifically, the connecting rod 3 is strip-shaped, with a connecting sleeve 2 at each end. The connecting rod 3 includes two connecting plates, with the connecting sleeves 2 welded to both ends of the connecting plates, and three reinforcing columns 4 positioned between the two connecting plates. The center distance tolerance of the connecting sleeves 2 is less than the center distance tolerance of the positioning columns required by the process. The flatness and perpendicularity of the two welded connecting sleeves 2 are <0.5 mm. Preferably, 45# steel, which has balanced mechanical properties, excellent machinability, high cost-effectiveness, and low cost, is selected as the material for manufacturing this positioning fixture.

[0036] The length of the connecting plate is equal to the center distance of the positioning pins required by the process. Both ends of the connecting plate have semi-circular notches for mating with the upper part of the connecting sleeve 2. The diameter of the semi-circular notches is equal to the diameter of the mating point with the connecting sleeve 2. High-precision control of the center distance of the positioning pins is achieved by controlling the center distance of the connecting sleeve 2. Rapid positioning of the positioning pin 1 is achieved through direct mating between the connecting sleeve 2 and the positioning pin 1. The reinforcing column 4 is used to improve the overall bending and torsional stiffness of the positioning fixture, increasing its service life. The flatness and perpendicularity of the two connecting sleeves of the welded parts are set to 0.2 mm.

[0037] In this embodiment, the two positioning posts 1 are located at the center of the upper surface of the front and rear main frames of the box, respectively. By controlling the center distance of the positioning posts 1, the installation position of the front and rear main frames is determined. By cooperating with the positioning holes on the bottom surface of the front and rear main frames of the upper box, the multi-layer stacking of the box is realized.

[0038] In use, first pre-assemble the front and rear main frames to the marked positions. Then, install the two positioning posts 1 onto the front and rear main frames respectively, and fix the front main frame according to the process dimensions. First, place the connecting sleeve 2 at one end of the positioning fixture onto the fixed positioning post 1 of the front main frame. Then, slowly tap the rear main frame with a mallet to indirectly adjust the position of the positioning post 1 on the rear main frame until the positioning post 1 on the rear main frame can fit onto the connecting sleeve 2 at the other end, thus achieving rapid positioning of the center distance of the positioning posts. After positioning is complete, remove the positioning fixture. This positioning fixture is easy and quick to install and remove, with a quick installation and removal time of ≤1 minute.

[0039] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
