Description

Technical Field

[0001] This utility model belongs to the field of nitrogen spring assembly technology, specifically relating to a nitrogen spring tooling tray. Background Technology

[0002] A nitrogen spring is a component with elastic properties. It seals high-pressure nitrogen gas in a defined container. An external force compresses the nitrogen gas through a piston rod. When the external force is removed, the high-pressure nitrogen gas expands to generate a certain elastic force. It mainly consists of a cylinder, guide seat, sealing ring, O-ring, and piston rod. Nitrogen springs are widely used not only in the mold industry but also in other industrial fields such as automotive, electronics, and instrumentation.

[0003] The assembly and production of nitrogen springs involves multiple workstations on a streamlined process, such as height and diameter checks of cylinder blocks and piston rods, oiling, bushing pressing, snap ring installation, nitrogen filling, pressure testing, and other procedures. Each process is connected by a dedicated conveyor line that transports the components or semi-finished products to be assembled. Specifically, each component is placed on a pallet and moved as a whole along the conveyor line to its respective workstation.

[0004] Due to the differences in shape and size of components such as nitrogen spring cylinders and piston rods, and the limitations of their pallet structure for assembly, each pallet can only carry one type of part. Parts to be assembled cannot be transported together. Therefore, when assembling at each workstation, the corresponding parts carried in each pallet need to be removed and assembled separately. This method affects the efficiency of assembly and is less flexible. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A nitrogen spring tooling tray, comprising:

[0007] At least one plate, the upper end of which is provided with several recessed holes for inserting nitrogen springs;

[0008] Side wings are connected to the side of the plate and are arranged around the outline of the plate;

[0009] Several connecting blocks are disposed at the lower part of the plate and connected to the side wing. The connecting blocks are connected end to end to form a downward convex structure that conforms to the shape of the side wing.

[0010] Furthermore, the connecting block has a first connecting lug and a second connecting lug with corresponding shapes on both sides.

[0011] Furthermore, a positioning protrusion is provided on the upper end of the connecting block along the length direction.

[0012] Furthermore, the upper edge of the connecting block has a folded portion, which forms a groove with the main body of the connecting block for the insertion of the side wings.

[0013] Furthermore, the side wing has several positioning through holes and fastening through holes distributed along its length.

[0014] Furthermore, the concave hole is a stepped hole.

[0015] Furthermore, the thickness of the plate is not less than 10 cm.

[0016] Furthermore, there are two plates.

[0017] Furthermore, the diameter of the recesses in each of the plates is equal.

[0018] Furthermore, the diameters of the recesses in each of the plates are not equal.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] By creating several recesses in the plate, multiple parts of the same or different types can be placed in these recesses and transported together with the pallet. Because the pallet has multiple connecting blocks on its side wing bottom, adjacent plates with recesses of different sizes can be connected in series through the combination of these blocks, forming a single unit that is transported simultaneously. This method allows for the flexible combination of multiple existing plates, enabling the simultaneous mixed transport of components such as cylinders and piston rods. Compared to traditional single-component transport, mixed transport improves the assembly efficiency of nitrogen springs at each workstation. Attached Figure Description

[0030] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] The accompanying drawings are for illustrative purposes only and represent schematic diagrams, not actual physical objects. They should not be construed as limiting the scope of this patent.

[0032] like Figure 1 - Figure 7 As shown, a nitrogen spring tooling tray of the present invention includes at least one plate 1, side wings 2 and several connecting blocks 3;

[0033] Among them, the upper end of the plate 1 is provided with several recessed holes 10 for inserting nitrogen springs 4;

[0034] Side wing 2 is connected to the side of plate 1 and is arranged around the outline of plate 1;

[0035] Connecting block 3 is located at the lower part of plate 1 and is connected to side wing 2. Several connecting blocks 3 are connected end to end to form a downward convex structure that conforms to the shape of side wing 2.

[0036] By creating several recesses 10 in the plate 1, multiple parts of the same or different types can be placed in the recesses 10 and transported together with the pallet. Since the bottom of the side wing 2 of the pallet is provided with multiple connecting blocks 3, by combining the connecting blocks 3, two adjacent plates 1 with recesses 10 of different sizes can be connected in series to form a whole that is transported at the same time. In this way, multiple existing plates 1 can be flexibly combined to transport cylinders, piston rods and other assembled parts together. Compared with the traditional single-part transport, mixed transport is beneficial to improving the assembly efficiency of nitrogen springs 4 at each workstation.

[0037] like Figure 6 , Figure 7 As shown, the connecting block 3 has a first connecting lug 31 and a second connecting lug 32 on each side. The first connecting lug 31 and the second connecting lug 32 are combined to form an interconnected structure. Specifically, the first connecting lug 31 and the second connecting lug 32 are respectively located at the upper and lower parts of the two ends. When adjacent connecting blocks 3 are combined, the first connecting lug 31 and the second connecting lug 32 are connected to make each connecting block 3 tightly connected. Using this connection method, the number of connecting blocks 3 can be selected according to the length of each side of the plate 1. Of course, the side length of the plate 1 and the length of the connecting block 3 are not arbitrary dimensions, but have a certain functional relationship, such as the side length of the plate 1 being an integer multiple of the length of the connecting block 3.

[0038] The first connecting lug 31 and the second connecting lug 32 can be connected by bolts.

[0039] like Figure 7 As shown, a positioning protrusion 33 is provided on the upper end of the connecting block 3 along the length direction, and several positioning through holes 20 are distributed on the side wing 2 along the length direction. Through the cooperation of the positioning protrusion 33 and the positioning through holes 20, the plate body 1 can be quickly positioned during assembly, so that the threaded holes are aligned and the connection is facilitated.

[0040] Specifically, fastening through holes 21 are distributed along the length direction on the side wing 2.

[0041] Furthermore, the upper edge of the connecting block 3 has a folded portion 34, which forms a groove 35 with the main body of the connecting block 3 for the insertion of the side wing 2. The folded portion 34 and the groove 35 make the connection with the side wing 2 more secure.

[0042] Of course, when assembling nitrogen springs 4 in small batches, a single tray can also be used for mixed assembly, such as... Figure 1 , Figure 2 As shown, the recess 10 can be configured as a stepped hole. This stepped hole has holes with diameters different from the inner diameter, which is suitable for inserting cylinders of different diameters and piston rods of different sizes.

[0043] To prevent the nitrogen spring 4 from shaking during pallet transport and causing any parts to fall off, the thickness of its plate 1 is no less than 10 cm. This ensures the depth of insertion into the plate 1 and the recess 10, resulting in greater stability.

[0044] In this embodiment, there are two plates 1, and the diameters of the recesses 10 in each plate 1 are equal or unequal.

[0045] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
