Abstract
Description
Technical Field
[0001] This utility model relates to the field of chain pin processing technology, specifically to an automatic chain pin pressing and positioning device. Background Technology
[0002] A pin is a standardized fastener that can provide both static fixation and relative movement with the connected parts. It is primarily used at the hinge joints of two parts to form a hinge connection. Pins are typically locked with cotter pins, ensuring reliable operation and easy disassembly. Chains can be connected using pins.
[0003] When installing a chain, a pressing device is needed to press the pins onto the connection points between the chains. However, most existing pressing devices are operated manually, which makes chain installation inefficient and time-consuming. Therefore, corresponding improvements are needed to address these issues.

[0006] The top of the pressing rod is equipped with an installation plate, and the top of the installation plate is equipped with a connecting rod. The outer surface of the connecting rod is equipped with a connecting block, and a lifting plate is installed on one side of the connecting block. An electric push rod is installed on one side of the top of the lifting plate, and the electric push rod is installed on the top of the mounting column. The bottom end of the mounting column is installed with the top of the worktable.
[0007] Preferably, support legs are installed on both sides of the bottom of the workbench, and mounting blocks are installed on both sides of the placement slot on one side of the workbench, with mounting holes provided inside the mounting blocks.
[0008] Preferably, a stop block is movably provided on one side of the interior of the placement groove, and mounting plates are installed on both sides of the stop block, with mounting bolts movably screwed into the interior of the mounting plates.
[0009] Preferably, the outer diameter of the bottom end of the mounting bolt is adapted to the inner diameter of the mounting hole, and the bottom end of the mounting bolt extends into the interior of the mounting hole and is movably screwed thereto.
[0010] Preferably, a mounting groove is provided on one side of the mounting column, and the bottom end of the lifting plate is located inside the mounting groove and is slidably connected to it.
[0011] Preferably, the bottom end of the electric push rod penetrates the inner wall of the top of the mounting groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] By incorporating components such as positioning plates, positioning holes, support legs, mounting blocks, mounting holes, stop blocks, mounting plates, mounting bolts, mounting columns, mounting grooves, electric push rods, lifting plates, connecting blocks, connecting rods, mounting discs, and pressing rods, the problem of low chain installation efficiency and time-consuming and labor-intensive operations caused by the manual pressing operation of most existing pressing devices can be effectively solved.
[0014] The user can place the chain to be installed inside the placement slot. Then, the stop block can be placed inside the placement slot on one side, so that the three inner walls of the placement slot and one side surface of the stop block can limit the chain. After that, the user can rotate the two sets of mounting bolts so that the bottom ends of the two sets of mounting bolts can extend into the corresponding mounting holes and be movably screwed into them, so that the stop block can be fixedly installed between it and the worktable.
[0015] Subsequently, the user can insert the pins into the connection points between the chains, with the pins located inside the positioning holes. After that, the user can activate several sets of electric push rods, causing one end of the lifting plate to slide downwards inside the mounting groove. This allows the connecting block and connecting rod to move downwards, which in turn allows the mounting plate and pressing rod to move downwards. Ultimately, the bottom end of the pressing rod can be aligned with the top end of the pin, pressing the pin downwards and completely pressing it to the connection point between the chains, thus completing the installation of the chains.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] To achieve the above objectives, according to Figures 1-4 As shown, this utility model provides the following technical solution: an automatic chain pin pressing and positioning device, including a workbench 1 for placing the chain, a placement groove 11 is provided on one side of the top of the workbench 1, and the inner walls on both sides of the placement groove 11 are respectively installed on one side of the positioning plate 12 near the top. One side of the placement groove 11 is open, and the user can place the chain into the interior of the placement groove 11 through this side. The positioning plate 12 has a positioning hole 13 inside. Support legs 14 are installed on both sides of the bottom of the workbench 1, and the two sets of support legs 14 can support the workbench 1. Mounting blocks 15 are installed on both sides of the workbench 1 near the placement groove 11, and mounting holes 16 are provided inside the mounting blocks 15. It also includes a pressing rod 37 for pressing the pin.
[0023] A mounting plate 36 is installed at the top of the pressing rod 37, and a connecting rod 35 is installed at the top of the mounting plate 36. A connecting block 34 is installed on the outer surface of the connecting rod 35, and a lifting plate 33 is installed on one side of the connecting block 34. An electric push rod 32 is installed on one side of the top of the lifting plate 33, and the electric push rod 32 is installed at the top of the mounting column 3. The bottom end of the electric push rod 32 penetrates the inner wall of the top of the mounting groove 31. The bottom end of the mounting column 3 is installed with the top of the workbench 1. A mounting groove 31 is opened on one side of the mounting column 3, and the bottom end of the lifting plate 33 is located inside the mounting groove 31 and is slidably connected to it.
[0024] A stop block 2 is movably installed on one side of the interior of the placement slot 11, and mounting plates 21 are installed on both sides of the stop block 2. The stop block 2 is T-shaped. Mounting bolts 22 are movably screwed into the interior of the mounting plates 21. The outer diameter of the bottom end of the mounting bolts 22 is adapted to the inner diameter of the mounting hole 16, and the bottom end of the mounting bolts 22 extends into the interior of the mounting hole 16 and is movably screwed into it.
[0025] In actual use, there are several sets of positioning plates 12, and the spacing between the several sets of positioning plates 12 corresponds one-to-one with the connection between the chains. That is, the installation position of the pin corresponds one-to-one with the several sets of positioning plates 12, so that the positioning plates 12 and the positioning holes 13 can position the pin. There are several sets of pressing rods 37, and the several sets of pressing rods 37 correspond one-to-one with the several sets of positioning plates 12. The pressing rods 37 are located directly above the positioning plates 12. Because there are several sets of pressing rods 37, all the parts installed with the pressing rods 37 are correspondingly provided with several sets.
[0026] In use, the user can place the chain to be installed inside the placement groove 11. After that, the stop block 2 can be placed inside the placement groove 11 on one side, so that the three inner walls of the placement groove 11 and one side surface of the stop block 2 can limit the chain. Then, the user can rotate the two sets of mounting bolts 22 accordingly, so that the bottom ends of the two sets of mounting bolts 22 can be inserted into the corresponding mounting holes 16 and movably screwed into them, so that the stop block 2 can be fixedly installed between it and the workbench 1.
