[0050] Please refer to Figures 1-6 , this embodiment provides a chain link disassembling and riveting head device 100. The chain link disassembling and riveting head device 100 includes a base 110, a driving unit 120, a positioning tooling 130, a disassembling nail 140, and a movable riveting head block 150;

[0051] The driving unit 120 is connected to the base 110; the positioning tooling 130 is connected to the base 110, and the positioning tooling 130 is used for positioning and installing the chain link 210;

[0052] Either the disassembling nail 140 or the movable riveting head block 150 is connected to the driving unit 120. The driving unit 120 is used to drive the disassembling nail 140 or the movable riveting head block 150 to move relative to the base 110 to eject the pin on the chain link 210 or press and rivet the exposed pin on the chain link 210.

[0053] Please refer to Figures 1-6, the working principle of the chain link removal and riveting head device 100 is as follows:

[0054] First of all, it should be noted that in this embodiment, the chain link removal and riveting head device 100 is used as an example for removing links and riveting heads of the wound chain 200. In other embodiments of the present invention, the chain link removal and riveting head device 100 can also be used for the link removal work or riveting head work of other chains 200;

[0055] In addition, in order to enable the chain link removal and riveting head device 100 to remove links and rivet heads of the chain 200, it includes a base 110, a driving unit 120, a positioning tooling 130, a link removal nail 140 and a movable riveting head block 150;

[0056] Among them, the link removal nail 140 and the movable riveting head block 150 are selectively connected to the driving unit 120, and the driving unit 120 is used to drive the link removal nail 140 or the movable riveting head block 150 to move relative to the base 110. Then, after the chain 200 to be processed is positioned and installed on the positioning tooling 130, the driving unit 120 can be used to drive the link removal nail 140 or the movable riveting head block 150 to move relative to the base 110, so as to be able to eject the pin on the link 210 or press-rivet the exposed pin on the link 210;

[0057] In the above content, it should be pointed out that when positioning the chain 200 through the positioning tooling 130, the method of positioning one or more links 210 to be processed through the positioning tooling 130 is adopted. That is, when removing links or riveting heads, based on the number of pins for removing links or riveting heads, when removing one pin, only the two links 210 connected by the pin need to be positioned. And when riveting the two pins on one link 210, only the link 210 corresponding to the pin needs to be positioned;

[0058] Based on the above content, please refer to Figures 1-6 , the working steps of the chain link removal and riveting head device 100 are as follows:

[0059] First, put the chain 200 to be removed from the link into the clamping plate, and position the pins to be ejected by positioning two of its links 210;

[0060] Subsequently, install the link removal nail 140 on the movable end of the driving unit 120, start the driving unit 120, so that the driving unit 120 moves along the axis direction of the pin corresponding to the link removal, and make the link removal nail 140 move towards the direction of the pin to a position where it abuts against the pin, and continue to move. Then, during the process of the movable end of the driving unit 120 moving in the downward pressing direction, the pin can be ejected from the link 210, thereby realizing the process of removing the link of the chain 200;

[0061] When a riveting head is required at the connection of the two chains 200, the two chains 200 are positioned and installed in the positioning tooling 130, and the movable riveting head block 150 is connected to the movable end of the driving unit 120. The driving unit 120 is started, so that the driving unit 120 moves along the axis direction of the pin shaft corresponding to the riveting head, and the movable riveting head block 150 presses on the pin shaft, thereby riveting the pin shaft in the chain 200 to realize the riveting process at the connection of the chain 200;

[0062] It should be noted that in this embodiment, by replacing the positioning work, the positioning and installation work of chains 200 of different specifications can be satisfied, and by adjusting the detaching nail 140 and the movable riveting head block 150, the detaching and riveting work of different specifications can be satisfied; thus, the chain detaching and riveting device 100 can satisfy the processing work of chains 200 of various specifications and has good versatility.

[0063] In summary, the chain detaching and riveting device 100 has a simple structure and is convenient to use. It can quickly perform the detaching work and the riveting work of the chain 200, thereby improving the processing efficiency of the chain 200 and reducing the labor intensity of the workers; in addition, it can also improve the processing quality of the chain 200 and its consistency.

[0064] Further, please refer to Figures 1-9 , in this embodiment, when configuring the driving unit 120, the driving unit 120 can adopt a structural setting method combining a motor and a hydraulic cylinder. The purpose is to quickly adjust the position of the detaching nail 140 or the movable riveting head block 150 in space by the rotation of the motor. When the detaching nail 140 or the movable riveting head block 150 is adjusted to the position in contact with the chain link 210 to be processed, a large external force can be applied to the detaching nail 140 or the movable riveting head block 150 through the action of the hydraulic cylinder, thereby improving its processing quality. At the same time, in this way, the processing efficiency can be improved and the processing consistency can be improved.

[0065] Further, please refer to Figures 1-9 , in this embodiment, to improve the disassembly and assembly efficiency of the detaching nail 140 and the movable riveting head block 150 with the movable end of the driving unit 120, a connecting seat is configured at the movable end of the driving unit 120, and the detaching nail 140 and the movable riveting head block 150 are selectively detachably connected to the connecting seat. In this way, the disassembly and replacement work of the detaching nail 140 and the movable riveting head block 150 can be quickly completed through the connecting seat, and when the detaching nail 140 and the movable riveting head block 150 are disconnected from the connecting seat, the connection method can be a threaded connection or a snap connection.

[0066] On the basis of the above structure, when configuring the workbench, its function is to install the positioning tooling 130 and the driving unit 120, and at the same time form the working space for machining the processing link 210. Thus, the base 110 of this embodiment is configured with a first workbench 111 and a second workbench 112; the positioning tooling 130 is connected to the first workbench 111, the driving unit 120 is connected to the second workbench 112, and the second workbench 112 is provided with a through hole 113 for the movable end of the driving unit 120 to pass through; wherein, the first workbench 111 and the second workbench 112 are arranged in parallel and at intervals to form an activity space for the split pin 140 or the movable riveting head block 150 connected to the connecting seat in the interval area between the two.

[0067] On the basis of the above structure, in order to improve the positioning efficiency of the positioning work with the first workbench 111 and improve the positioning accuracy, therefore, the first workbench 111 is configured with a positioning hole 114 for installing the positioning tooling 130. In this way, when positioning and installing the positioning tooling 130, the structure on the positioning tooling 130 can be matched with the positioning hole 114 to complete the positioning and installation steps, thereby improving the positioning and installation efficiency of the positioning tooling 130.

[0068] Furthermore, in this embodiment, when configuring the positioning tooling 130, in order to enable the positioning tooling 130 to meet the processing requirements of splitting the link and riveting the head, therefore, the positioning tooling 130 includes a link-splitting positioning member 160 and a riveting-head positioning member 170, and the link-splitting positioning member 160 and the riveting-head positioning member 170 are selectively matched with the positioning hole 114;

[0069] Among them, the link-splitting positioning member 160 is used to position and install the link 210, and make the axis of the pin to be split of the link 210 coincide with the axis of the split pin 140, and guide the pin to withdraw when the split pin 140 ejects the pin, that is, the link-splitting positioning member 160 is used for the link-splitting work of the chain 200;

[0070] The riveting-head positioning member 170 is used to position and install the link 210, and abut against the pin to be press-riveted of the link 210 or abut against the link plate of the link 210; that is, the riveting-head positioning member 170 is used for the riveting-head work of the chain 200;

[0071] Thus, during the use process, according to the use requirements, by replacing the link-splitting positioning member 160 and the riveting-head positioning member 170, the processing requirements of splitting the link and riveting the head of the chain 200 can be met. In this way, the purpose is to have corresponding positioning tools to meet the positioning and processing requirements during the link-splitting and riveting-head processing of the link 210, so as to improve the processing quality through this way.

[0072] Please refer to Figures 1-9, when configuring the joint-separating positioning member 160 and the riveting head positioning member 170, to improve their positioning accuracy on the first workbench 111, therefore, the joint-separating positioning member 160 and the riveting head are configured with positioning posts 115 that cooperate with the positioning holes 114. The inner peripheral surface of the positioning hole 114 is provided with a first positioning portion; the outer peripheral surface of the positioning post 115 is provided with a second positioning portion for cooperating with the first positioning portion. Moreover, the first positioning portion extends along the axial direction of the positioning hole 114, and one of the first positioning portion and the second positioning portion is a groove, and the other is a protrusion. That is, through the foregoing structural settings, while positioning through the cooperation of the positioning hole 114 and the positioning post 115, the rotation of the positioning post 115 in the positioning hole 114 can be limited through the cooperation of the groove and the protrusion, thereby improving its positioning accuracy and facilitating the improvement of the processing quality of the chain 200.

[0073] Based on the above, when configuring the joint-separating positioning member 160, its function is to position and install the link 210, make the axis of the pin to be separated of the link 210 coincide with the axis of the joint-separating nail 140, and guide the pin to exit when the joint-separating nail 140 ejects the pin;

[0074] Based on this, through the cooperation of the above positioning hole 114 and positioning post 115, its positioning on the first workbench 111 can be completed, so as to determine its relative position relative to the drive unit 120 of the second workbench. Please refer to Figures 1-12 , the joint-separating positioning member 160 includes a first clamping plate 161 and a second clamping plate 162, and the first clamping plate 161 is connected to the second clamping plate 162; the first clamping plate 161 is configured with two spaced-apart positioning protrusions 163, and the two positioning protrusions 163 are used for inserting into the gaps between two links 210 adjacent to the pin; the second clamping plate 162 cooperates with the positioning hole 114, that is, the positioning post 115 is arranged on the second clamping plate 162, and the second clamping plate 162 is also provided with a relief groove 164, the relief groove 164 is directly opposite to the pin, and extends along the axial direction of the pin toward the side away from the drive unit 120.

[0075] Thus, through the above structural settings, the two protrusions can be inserted into the gaps between two links 210 adjacent to the pin, thereby positioning the link. Subsequently, when the drive unit 120 drives the joint-separating nail 140 to approach the pin in the direction of the pin, since the axial direction of the joint-separating nail 140 coincides with the axial direction of the pin, therefore, after the joint-separating nail 140 abuts against the pin, on the basis of its continuous movement in the same direction, the pin can be ejected from the link 210, and the ejected pin will extend into the relief groove 164, thereby completing the joint separation of the link 210.

[0076] When configuring the riveting head positioning member 170, please refer to Figures 1-14, based on the structures of the positioning holes 114 and positioning posts 115 described above, it can position its position on the first workbench 111, and at the same time can determine its position relative to the driving unit 120 and the movable riveting head block 150 connected to the driving unit 120;

[0077] Specifically, the riveting head positioning member 170 provided in this embodiment includes a mounting seat 171, a fixed riveting head block 172 and a movable seat 173; the mounting seat 171 cooperates with the positioning hole 114, the movable seat 173 is detachably connected to the mounting seat 171, and together form the positioning area of the mounting link 210, and the fixed riveting head block 172 is connected to the mounting seat 171 and is located in the positioning area; wherein, the fixed riveting head block 172 is used to abut against the pin to be riveted or abut against the link plate of the link 210.

[0078] Moreover, the movable seat 173 is configured with a plug-in portion 174 extending towards the positioning area, and the plug-in portion 174 is used to be plugged into the gap of the link 210 in the positioning area.

[0079] Thus, through the above structural settings, after the link 210 is connected to the positioning area of the movable seat 173 and the mounting seat 171, the plug-in portion 174 on the movable seat 173 is plugged into the gap of the link 210 in the positioning area, and then the positioning of the connection can be completed. At this time, the side of the link 210 along the axis of its pin away from the driving unit 120 abuts against the fixed riveting head block 172;

[0080] Subsequently, under the driving action of the driving unit 120, it moves towards the direction close to the pin. At this time, the exposed end of the pin on the link 210 faces the movable riveting head block 150 on the driving unit 120. Then, after the movable riveting head block 150 abuts against the exposed end of the pin, it can be riveted. At this time, the movable riveting head block 150 and the fixed riveting head block 172 are located at both ends along the axis of the pin.

[0081] In summary, please refer to Figures 1-14 , the chain link disassembling and riveting head device 100 has a simple structure. Through the setting of the positioning tooling 130, it can meet the processing requirements of disassembling and riveting; and by replacing the positioning tooling 130, it can meet the processing requirements of chains 200 of different specifications, thereby expanding its application range, improving its versatility, and reducing its use cost; that is, it can realize the disassembly of the standard chain 200, and by replacing the disassembly positioning member 160 and the disassembly nail 140, the disassembly of multi-specification chains 200 can be realized; it can realize the riveting of the standard chain 200, and by replacing the riveting head positioning member 170 and the riveting head block, the riveting of multi-specification chains 200 can be realized;

[0082] Moreover, it is convenient to use. Based on the settings of the driving unit 120 and the structures of the base 110 and the positioning tooling 130, the movement precision of the driving unit 120 for driving the joint removing nail 140 and the movable riveting head block 150 can be improved, thereby improving the processing quality. Also, the joint removing work and the riveting work of the chain 200 can be carried out quickly, thus improving the processing efficiency of the chain 200 and reducing the labor intensity of workers.

[0083] In addition, through the setting of the driving unit 120, the external force during the joint removing and riveting processes can be unified, thereby improving the processing quality and consistency during the batch processing of the chain 200.

[0084] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
