Description

Technical Field

[0001] The utility model relates to the technical field of factory assembly line equipment, in particular to a workbench chain self-locking mechanism. Background Art

[0002] An assembly line workbench is a workbench used to assemble, process or produce products, usually in the manufacturing and production fields. It usually consists of one or more workbenches, on which transmission rollers are set so that products can move smoothly between the workbenches. Assembly line workbenches are usually designed in a modular structure so that they can be flexibly laid out and adjusted according to production needs. Operators can operate on the assembly line workbench according to the predetermined process flow to complete the assembly, processing or treatment of products.

[0003] Normally, AGV (Automated Guided Vehicle) transfers goods to the workbench for storage. However, since the goods have inertia when they are moving, they will continue to slide due to inertia when they are transferred to the workbench, and even slide off the workbench. In another case, because the worker accidentally touches the goods stored on the workbench, the transmission roller rotates in the opposite direction, causing the goods to slide off the workbench. Both cases will cause the goods to slide off the workbench. Utility Model Content

[0004] The utility model aims to provide a workbench chain self-locking mechanism, which can solve the problem that goods easily slide off the workbench.

[0005] The purpose of this utility model is achieved through the following technical solutions:

Power transmission is achieved between two adjacent transmission rollers 11 by sleeved with the chains 12. The self-locking mechanism is installed below the chains 12. The self-locking mechanism comprises an active arm 13, at least two fixed seats 14, a driven arm 15, a counterweight 16 and a contour tooth 17, wherein the two fixed seats 14 are fixed on the inner side of the workbench 1. The middle part of the active arm 13 and the middle part of the driven arm 15 are respectively rotatably mounted on one side of the fixed seat 14 through hinge pins. One end of the driven arm 15 close to the active arm 13 is rotatably connected to one end of the active arm 13 and is installed with the contour tooth 17, and the other end is installed with the counterweight 16.

[0021] Embodiment 1

[0022] A workbench chain self-locking mechanism, such as Figure 1-2 As shown, it includes a workbench 1 equipped with a self-locking mechanism, and a plurality of transmission rollers 11 and chains 12 are arranged on the workbench 1. Power transmission is achieved between two adjacent transmission rollers 11 by sleeved with the chains 12. The self-locking mechanism is installed below the chains 12. The self-locking mechanism includes an active arm 13, at least two fixed seats 14, a driven arm 15, a counterweight 16 and a contour tooth 17, and the two fixed seats 14 are fixed on the inner side of the workbench 1. The middle part of the active arm 13 and the middle part of the driven arm 15 are respectively rotatably mounted on one side of the fixed seat 14 through hinge pins. One end of the driven arm 15 close to the active arm 13 is rotatably connected to one end of the active arm 13 and is installed with the contour tooth 17, and the other end is installed with the counterweight 16.

[0023] In this embodiment, the self-locking mechanism can be provided with multiple sets of active arms 13, fixed seats 14 and driven arms 15 to extend the overall length. The shapes and sizes of the active arms 13 and driven arms 15 can be changed to adapt to different actual mechanical conditions. The fixed seat 14 can be fixed to the inner side of the workbench 1 by bolts or welding. The counterweight 16 can be installed at one end of the driven arm 15 by bolts or welding.

[0024] Further, a slide groove 151 is provided at one end of the driven arm 15 connected to the active arm 13. Further, a cam 131 is provided at one end of the active arm 13 connected to the driven arm 15, and the cam 131 is slidably installed in the slide groove 151.

[0025] Further, the driven arm 15 is located below the active arm 13 in the vertical direction. Further, one end of the driven arm 15 connected to the active arm 13 extends upward. Further, one end of the active arm 13 connected to the driven arm 15 extends downward.

[0026] In this embodiment, the heights of both ends of the active arm 13 and the driven arm 15 are adjusted according to actual conditions, the main function of which is to allow the driven arm 15 to have enough space to rotate so that the contoured teeth 17 can clamp the chain 12 upwards and unlock the chain 12 downwards.

[0027] Working principle:

[0028] like Figure 4 As shown, when the AGV (automatic guided vehicle) abuts against the workbench 1, or other external forces act to raise the active arm 13 away from one end of the driven arm 15, the active arm 13 rotates around the fixed seat 14, and the end of the active arm 13 connected to the driven arm 15 moves downward, driving the contour tooth 17 to move downward, thereby unlocking the chain 12, the chain 12 can rotate, and the transmission roller 11 rotates to drive the object above to move.

[0029] like Figure 3 As shown, when the AGV (automatic guided vehicle) evacuates the workbench 1, or other external forces do not act on the end of the active arm 13 away from the driven arm 15, the counterweight 16 is lowered by gravity, driving the end of the driven arm 15 away from the active arm 13 to lower, the driven arm 15 rotates around the fixed seat 14, and the end of the driven arm 15 connected to the active arm 13 moves upward, driving the contour tooth 17 to move upward, thereby blocking the chain 12, the chain 12 cannot rotate, the transmission roller 11 stops rotating, and the object on the transmission roller 11 cannot move easily. The workbench chain is self-locking.

[0030] The utility model uses the gravity of the counterweight block to make the profiled tooth installed at the other end of the driven arm move upward and be clamped in the gap on the chain to prevent the chain from rotating, thereby solving the problem that objects are easy to move on the workbench.

[0031] In the description of the present invention, it should be understood that the terms "middle", "length", "up", "down", "front", "back", "vertical", "horizontal", "inside", "outside", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0032] In the present invention, unless otherwise clearly specified and limited, the first feature "on" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. "Multiple" means at least two, such as two, three, etc., unless otherwise clearly and specifically limited.
