Description

Technical Field

[0001] The utility model relates to the technical field of chain conveyors, in particular to an assembly device for flat outer chain plates of chain conveyors. Background Art

[0002] In the field of engineering and manufacturing, chains are a common transmission device used to transfer power from one place to another. Chains are widely used in various industrial equipment and machinery, such as conveyors, motorcycles, bicycles, construction machinery, etc. Each application scenario may require a specifically designed chain to meet specific requirements and environmental conditions. At present, the installation of chains still relies more on manual operation, but manual operation often leads to a series of problems.

[0003] The Chinese patent document with publication number CN221270385U discloses a special fixture for metal chain processing, including a workbench, a rotating shaft is passed through one end of the top surface of the workbench, and an L-shaped support seat is fixedly provided at the other end. A cylinder is fixedly provided on the top surface of the rotating shaft, and a mounting groove is opened in the middle of the cylinder in the height direction. An abutment plate that can slide up and down is arranged in the mounting groove. A turntable is also arranged on the outer side surface of the rotating shaft extending out of the workbench, and a fixed seat is also arranged on the top surface of the workbench away from the L-shaped support seat at a position corresponding to the end of the turntable, and an arc groove that allows the turntable to pass through is also opened on the inner end surface of the fixed seat, and a fixing device that can position the turntable is also provided in the middle position of the arc groove.

[0004] In the last step of chain assembly, the flat outer chain plate needs to be crimped between two chain link units to form a continuous chain, and in order to ensure the stability of the crimping, the two chain link units need to have sufficient positional accuracy. In the above patent solution, only a single chain plate and a single chain hole can be assisted in positioning, and it cannot be applied to the chain assembly process, so the applicability is limited. A single chain often has many chain link units, so this also requires that the clamping device of the chain link unit needs to be easy to operate. Utility Model Content

[0005] In order to overcome the technical problems in the prior art that during the chain assembly process, the link units need to be accurately positioned, and due to the large number of link units, the positioning state needs to be frequently switched; one purpose of the utility model is to provide a chain conveyor chain flat outer chain plate assembly device, by providing two elastic positioning columns, and providing inclined surfaces that can be driven by rollers on the chain on the positioning columns, the positioning columns are inserted between two adjacent rollers under the action of elastic force for positioning, and the horizontal movement of the chain drives the inclined surface to automatically release the positioning state.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a chain conveyor chain flat outer chain plate assembly device, including a hydraulic press and a support platform arranged on the hydraulic press; two positioning parts are symmetrically arranged on the support platform, and the chain passes through the middle of the two positioning parts; the positioning part includes a mounting shell, a positioning column slidably connected in the mounting shell, and a spring arranged between the mounting shell and the positioning column; the elastic force of the spring is used to make the positioning column slide in the direction of the chain; wherein, an inclined surface is arranged on one side of the outer end of the positioning column, and the other side of the outer end of the positioning column and the inclined surface are respectively against two adjacent rollers.

[0007] During the crimping process of the hydraulic press, the hydraulic pressure is in a nonlinear change, and sufficient position accuracy is required to enable the flat outer chain plate to achieve stable crimping under precise pressure control; the two positioning posts are inserted into the chain at the same time, and are against the two adjacent rollers, so that the chain is positioned, which is convenient for the smooth crimping process; after the crimping is completed, while the chain is pulled to adjust the position, the roller drives the inclined surface to make the positioning post leave the chain, and then, after the position adjustment is completed, the two adjacent rollers are again facing the positioning post, and then the chain is fixed again. In this way, the operation process can be greatly simplified, the working cycle can be reduced, and the work efficiency of chain assembly can be improved.

[0008] Furthermore, a guide structure is provided on the upper end of the support platform for enabling the chain to slide only horizontally linearly; the other side of the outer end of the positioning column and the inclined surface respectively abut against two rollers on the same chain link unit; one end of the crimped flat outer link plate is located directly above the roller abutting against the inclined surface.

[0009] The positioning column is inserted into the link unit instead of between two link units, which can further improve the stability of the chain being fixed, avoid slight bending on the chain, improve the success rate of crimping, and facilitate the position adjustment of the chain.

[0010] Optionally, the guide structure is a linear slide groove arranged on the upper end of the support platform; the lower end of the chain is located in the linear slide groove.

[0016] Specifically, an air hole is provided at one end of the mounting shell away from the positioning column; and the air hole is communicated with the interior of the mounting shell.

[0017] The presence of the air hole prevents the installation shell from being liquid sealed in the presence of lubricating oil, and while ensuring lubricity, it also facilitates the sliding of the positioning column relative to the installation shell.

[0018] Furthermore, a notch is provided on the side of the mounting shell facing the chain; a limiting plate is provided on the side of the positioning column away from the chain; the limiting plate is located in the mounting shell, and the width of the limiting plate is greater than the width of the notch.

[0019] Specifically, the mounting shell includes a cavity shell and a cover body detachably connected to the upper end of the cavity shell; the upper end of the cavity shell is provided with a sliding cavity slidably connected to the limit plate; the spring is located in the sliding cavity and its two ends are respectively against the inner wall of the sliding cavity and the limit plate.

[0020] Furthermore, two positioning brackets are symmetrically arranged on the upper end of the supporting platform; and the mounting shell is arranged on the upper end of the positioning brackets.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The positioning column is inserted into the chain under the action of elastic force to position it, which is convenient for the installation of the flat outer chain plate; at the same time, after the installation is completed, the horizontal movement of the chain can synchronously drive the positioning column to move out of the chain, which is convenient for the position adjustment of the chain, simplifies the operation steps, reduces the process cycle, and helps to improve work efficiency.

[0023] 2. The setting of the oil guide groove and the oil filling hole ensures the smooth sliding of the positioning column in the mounting shell, reduces the pulling force required to pull the chain to adjust the position, facilitates manual operation, and also increases the service life of the positioning part.

[0024] 3. The setting of the guide structure further provides a positioning basis for the fixation of the chain, and also facilitates the horizontal movement and adjustment of the chain, further simplifying the processing flow and improving assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
