Description

Technical Field

[0001] This utility model relates to the field of chain assembly technology, specifically to a chain assembly mold. Background Technology

[0002] Chains can be classified into roller chains, toothed chains, and other types according to their structure, with roller chains being the most widely used. The structure of a roller chain consists of inner link plates, outer link plates, pins, bushings, and rollers. The inner link plates and bushings, and the outer link plates and pins are fixed together by interference fits, called inner and outer link links; the rollers and bushings, and the bushings and pins are connected by clearance fits.

[0003] According to Chinese Patent Application No. CN202223429673.8, a chain assembly mold is disclosed, including a mold base. Guide seats are provided on both the left and right sides of the mold base. A sliding hole is opened between the guide seats and the mold base. A guide support column is slidably connected in the sliding hole. A first step and a second step are provided on the guide support column. An elastic thrust device is provided between the bottom of the guide support column and the mold base. A limit groove is opened on the side of the guide support column. A limit block adapted to the limit groove is installed on the guide seat. During assembly, the inner chain plate is first sleeved on the second step. Under the thrust of the elastic thrust device, the limit block limits the bottom of the limit groove, so that the guide support columns on the left and right sides are at the same height, thereby allowing the inner chain plate to be placed horizontally. Then, the sleeve is sleeved on the first step, so that the sleeve and the sleeve mounting hole on the inner chain plate are vertically aligned.

[0004] Currently, there are still some shortcomings in the chain assembly mold. For example, when the chain pieces are of different sizes during use, the spacing between the holes between the chain pieces is different. The guide support column of the device is fixed in position, which limits the chain assembly and cannot meet the assembly of chains of different sizes. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a chain assembly mold, which solves the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A chain assembly mold includes: an assembly table, a hydraulic frame fixedly mounted on the top surface of the assembly table, a hydraulic press fixedly mounted on the top surface of the hydraulic frame, a punch provided on the bottom surface of the hydraulic frame, a shaft of the hydraulic press fixedly connected to the punch, an assembly block provided inside the assembly table, a positioning element provided inside the assembly block, a chain link provided on the top surface of the assembly block, a roller provided on the top surface of the chain link, another chain link provided on the top surface of the roller, and a chain pin provided inside the roller; and an adjustment component provided on the top surface of the assembly block for adjusting the positioning element.

[0008] Preferably, the adjustment assembly includes: an adjustment groove, the adjustment groove being formed on the top surface of the assembly block, a bidirectional lead screw being rotatably installed on one side of the adjustment groove, two adjustment blocks being threaded to the outside of the bidirectional lead screw, an adjustment hole being formed on one side of the assembly table, an adjustment head being rotatably installed inside the adjustment hole, and the adjustment head being fixedly connected to the bidirectional lead screw.

[0009] Preferably, the positioning element includes: a positioning hole, the positioning hole being formed on the top surface of the adjusting block, and a positioning post being movably sleeved inside the positioning hole.

[0010] Preferably, a limit block is provided inside the positioning hole, the positioning post is fixedly connected to the limit block, and a spring is provided inside the positioning hole.

[0011] Preferably, a connecting ring is fixedly installed on one side of the assembly block, and a threaded hole is opened on one side of the assembly table. A screw is threadedly connected inside the threaded hole, and the screw is rotatably connected to the connecting ring.

[0012] Preferably, two guide rods are fixedly installed on one side of the assembly table, and the assembly block is movably sleeved with the guide rods.

[0013] In summary, the present invention has the following main advantages:

[0014] By setting up an adjustment component, when the worker places the chain link on the adjustment block, the positioning pin on the adjustment block positions the chain link, preventing the chain link from shifting during assembly. After the chain link is positioned, the punch presses against the chain pin, creating an interference fit between the chain pin, the chain link, and the roller. The chain pin, under pressure, presses down on the positioning pin on the adjustment block. At this time, the spring is compressed, causing the positioning pin to retract into the adjustment block, thus allowing the chain pin to have an interference fit with the chain link below. When assembling chain links of different sizes, the hole spacing between the chain links of different sizes is different. The worker can rotate the adjustment head, which drives the double-sided lead screw to rotate, causing the two adjustment blocks to move inward or outward. This allows the spacing of the positioning components on the adjustment block to be adjusted according to the spacing between the chain links being assembled, thus adapting to the assembly of chain links of different sizes and meeting production needs.

[0020] 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.

[0021] refer to Figures 1-4A chain assembly mold includes: an assembly table 1, a hydraulic frame 2 fixedly mounted on the top surface of the assembly table 1, a hydraulic press 3 fixedly mounted on the top surface of the hydraulic frame 2, a punch 4 provided on the bottom surface of the hydraulic frame 2, a shaft of the hydraulic press 3 fixedly connected to the punch 4, an assembly block 5 provided inside the assembly table 1, a positioning component provided inside the assembly block 5, a chain piece 9 provided on the top surface of the assembly block 5, a roller 16 provided on the top surface of the chain piece 9, another chain piece 9 provided on the top surface of the roller 16, and a chain pin 17 provided inside the roller 16; and an adjustment component provided on the top surface of the assembly block 5 for adjusting the positioning component.

[0022] By setting the punch 4, after the worker places the chain piece 9 on the assembly block 5 through the positioning part, and then installs the roller 16 and another chain piece 9 on the chain piece 9, and inserts the chain pin 17, the chain component can be quickly press-fitted by the combination of the hydraulic press 3 and the punch 4. This reduces the time of manual operation, increases the assembly speed, and is very suitable for mass production.

[0023] As a further embodiment of this utility model, the adjustment component includes: an adjustment groove 6, which is opened on the top surface of the assembly block 5; a bidirectional lead screw 7 is rotatably installed on one side of the inner side of the adjustment groove 6; two adjustment blocks 8 are threadedly connected to the outer side of the bidirectional lead screw 7; an adjustment hole 14 is opened on one side of the assembly table 1; an adjustment head 15 is rotatably installed inside the adjustment hole 14; and the adjustment head 15 is fixedly connected to the bidirectional lead screw 7.

[0024] By setting an adjustment component, when assembling chain links 9 of different sizes, the hole spacing between chain links 9 of different sizes is different. The operator can rotate the adjustment head 15, which drives the bidirectional lead screw 7 to rotate, causing the two adjustment blocks 8 to move inward or outward. This allows the spacing of the positioning parts on the adjustment blocks 8 to be adjusted according to the spacing between the chain links 9 being assembled, thus adapting to the assembly of chain links 9 of different sizes and meeting production needs.

[0025] As a further embodiment of this utility model, the positioning component includes: a positioning hole 10, which is opened on the top surface of the adjusting block 8, and a positioning post 11 is movably sleeved inside the positioning hole 10.

[0026] By setting the positioning post 11, when the worker places the chain piece 9 on the adjusting block 8, the positioning post 11 on the adjusting block 8 will position the chain piece 9 to prevent the position of the chain piece 9 from shifting during the assembly process and affecting the assembly quality.

[0027] As a further embodiment of this utility model, a limiting block 12 is provided inside the positioning hole 10, the positioning post 11 is fixedly connected to the limiting block 12, and a spring 13 is provided inside the positioning hole 10.

[0028] By setting the spring 13, after the chain piece 9 is positioned, the punch 4 presses against the chain pin 17, so that the chain pin 17 is in an interference fit with the chain piece 9 and the roller 16. The chain pin 17 is pressed down and presses against the positioning post 11 on the adjusting block 8. At this time, the spring 13 is in a compressed state, so that the positioning post 11 retracts into the adjusting block 8, thereby enabling the chain pin 17 to be in an interference fit with the chain piece 9 below.

[0029] As a further embodiment of this utility model, a connecting ring 18 is fixedly installed on one side of the assembly block 5, and a threaded hole 20 is opened on one side of the assembly table 1. A screw 19 is threadedly connected inside the threaded hole 20, and the screw 19 is rotatably connected to the connecting ring 18.

[0030] By setting the screw 19, during assembly, the assembly block 5 is located on one side of the punch 4. After assembly, when stamping is required, the operator rotates the screw 19 to move the assembly block 5 below the punch 4 for stamping. After stamping is completed, the screw is rotated in the opposite direction to move the assembly block 5 to a position close to the edge of the assembly table 1, which is beneficial to the safety of the operator during the operation.

[0031] As a further embodiment of this utility model, two guide rods 21 are fixedly installed on one side of the interior of the assembly table 1, and the assembly block 5 is movably sleeved with the guide rods 21.

[0032] By setting guide rod 21, the assembly block 5 is limited during the movement of the assembly block 5, ensuring the stability of the assembly block 5 during the movement and preventing positional deviation.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
