[0002] At present, chain as a kind of mechanical transmission device, plays an important role in many fields. They are widely used in industrial automation, material handling, automobile manufacturing, food processing and other industries. With the promotion of industry 4.0 and intelligent manufacturing, the performance requirements of chain are higher and higher, such as high precision, high efficiency, low noise and long service life. Common chain is usually composed of a plurality of chain links that can swing relative to each other and a pin shaft that connects adjacent two chain links, and each chain link generally contains a pair of chain plates. Of course, considering the effect of reducing friction during rotation, some chains also have sleeve components installed on the outside of the pin shaft.

[0003] In the process of producing chain links or assembling chains, the pin shaft needs to be inserted between two overlapping chain links, and the accuracy of the pressing process greatly affects the stability and durability of the chain during long-term operation of the equipment. Therefore, special molds or equipment are usually used to position the chain links during the process to prevent them from deflecting and shaking during pressing, which affects the quality of the final chain product.

[0032] The following specific embodiments are only an explanation of the utility model, and are not a limitation of the utility model. Those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.

[0033] The present scheme is realized through the following technical means:

[0034] Embodiment: In the embodiment, a kind of chain product is given to the chain plate A between the two sides of single chain link, still be equipped with the roller B component type, can realize more stable and accurate press mounting effect's worktable for the roller chain press mounting and the roller chain press mounting assembly equipment comprising the worktable.

[0035] First, in the embodiment, the structure of the product to be produced and processed to obtain the roller chain needs to be explained first.In here, with reference to the attached drawings of the specification Figure 1The provided structural diagram shows that the smallest unit of this roller chain includes a roller B component located in the middle. Two chain plates A are respectively fitted onto both sides of roller B, belonging to the same link on one side. Another pair of chain plates A are symmetrically fitted onto the outer sides of these two chain plates A, belonging to the same link on the opposite side. When the pin C passes through these rollers B and chain plates A in sequence, the connection between the components is achieved, allowing roller B to rotate around its central axis, and the chain links on both sides to rotate relative to each other around a common central axis. Of course, for smoother rotation, bushing components can be pre-installed between the components.

[0036] For the chain product with roller B mentioned above, whether in the process of producing a single chain link or in the process of connecting two separate chain links, a thin pin C needs to be inserted into the chain plate A and roller B. However, if manual positioning is required during the pressing process, there is a significant risk. If the pressing is performed directly, the roller B and chain plate A components placed on top of each other are prone to shifting, resulting in deformation and damage to the product after pressing.

[0037] To address the aforementioned problems, the roller chain press-fitting workbench described in this embodiment employs an improved and optimized solution, effectively preventing product component wobbling and displacement during the press-fitting process and achieving precise positioning. For details, please refer to the appendix to the instruction manual. Figure 2 As shown, the workbench, as part of the assembly equipment for pressing with roller chains, is located inside the recessed working area 701 on the front side of the main body 7 of the equipment. The drive device 8 included in the equipment is a lifting support cylinder, and the pressure plate component 5 included in the workbench is connected to the end of the lower movable output end of the cylinder device, and can also move vertically.

[0038] For the workbench that achieves stable pressing, refer to the appendix of the instruction manual for its main structure. Figure 3As shown, comprising the lower bearing platform 1 and cover installed on the bearing platform 1 above the limit support plate 2; the bearing platform 1 is provided with a mounting hole slot 101 extending vertically from the upper surface, and a supporting spring 3 is arranged in the mounting hole slot 101; the limit support plate 2 is provided with a through hole 201 and an adjustable positioning pin column 4 is arranged, the positioning pin column 4 comprises an upwardly extending cylindrical segment 401 capable of passing through the through hole 201, and a limiting portion 402 capable of abutting with the lower surface of the limit support plate 2, the cylindrical segment 401 can be inserted into the hole of the chain plate A and the roller B above the through hole 201 to position the chain plate A and the roller B, and the lower surface of the limiting portion 402 abuts with the upper end of the supporting spring 3, and the limiting portion 402 can move up and down in the mounting hole slot 101.

[0039] It should be noted that the diameter of the cylindrical segment 401 formed on the positioning pin column is close to the hole diameter of the hole of the chain plate A and the roller B, but will not exceed the hole diameter, that is, it is a kind of clearance fit relationship. When positioning and installing in this state, when the cylindrical segment 401 coincides with the axial direction of the hole, the cylindrical segment 401 can pass through each component smoothly. Correspondingly, the connection relationship between the pin shaft C and the chain plate A and the roller B is an interference fit, so a large downward pressure force is required to be provided by the upper pressing plate component 5 to realize the press fitting connection, and to prevent loosening and falling out after installation.

[0040] Referring to the schematic diagram Figure 4 and 5 The cylindrical segment 401 passes through each component upwardly to realize accurate positioning and fixing of the components before the press fitting process. Then, when the pin shaft C component is in an upright state and is supported above the chain plate A by the sleeve, the pressing plate component 5 is pressed downwardly to push the spool into the chain plate A and the roller B from top to bottom under the drive of the driving device 8. At the same time, during the process, as the pin shaft C moves downwardly, the positioning pin column 4 originally positioned in the chain plate A and the roller B is pushed out downwardly until it is completely separated from the roller B and the chain plate A.

[0041] Preferably, in order to keep the positioning pin member 4 upright during the lifting movement and make the movement more smooth, the limiting part 402 is made in a disc shape, so that the inner wall surface of the mounting hole groove 101 and the outer wall surface of the limiting part 402 are in abutment. Further, a plurality of mounting hole grooves 101 are provided on the carrier plate 1, and a plurality of through holes 201 are provided on the limiting support plate 2, and the positioning pin member 4 and the supporting spring 3 are respectively installed in the mounting hole groove 101 and the through hole 201. Such a structure allows the compression of multiple pin shafts C in one compression process.

[0042] Since the position of the product placed below the pressing plate member 5 is not unique, and the number of components in a single compression process is adjusted according to the actual compression requirement, the upward resistance force on the pressing plate member 5 is not uniform. Therefore, in order to ensure the stable linear movement of the pressing plate member 5 during the compression process, a positioning guide mechanism 6 is formed between the pressing plate member 5 and the carrier plate 1, which includes a guide column 601 and a guide groove 602 extending in the vertical direction on the pressing plate member 5 and the carrier plate 1 respectively. As shown in the drawings, a plurality of positioning guide mechanisms 6 are provided on the outer periphery of the pressing plate member 5 and the carrier plate 1, so that the four corners of the flat block-shaped pressing plate member 5 can move up and down more uniformly and synchronously, thereby improving the compression precision and uniformity of the compression effect of the chain product with rollers B at different positions.

Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.​
