Description

Technical Field

[0001] This utility model relates to the field of chain production and processing technology, and in particular to a chain connecting piece assembly equipment with a safety device. Background Technology

[0002] With economic development and rapid industrial growth, large chains are increasingly used in industrial equipment. However, due to their numerous parts and the lack of dedicated assembly equipment, manual assembly of large chains is inefficient, requiring multiple processes and time-consuming. Furthermore, material jams and shortages can occur during assembly, and if not detected in time, it is difficult to identify missing internal parts, which can seriously affect the quality of the chain and make subsequent replacement of parts inconvenient. Therefore, improvements are necessary. Utility Model Content

[0003] This utility model provides a chain connecting piece assembly device with a safety device that can automatically produce and assemble chains with high assembly efficiency. It is applicable to the assembly of various irregularly shaped chains, significantly reduces the need for manual labor, meets higher production demands, and effectively avoids material jamming and shortage during chain assembly, ensuring the integrity of the chain assembly. It solves the technical problems of low assembly efficiency of large chains, low efficiency of manual assembly, inability to guarantee chain quality, inability to meet higher production demands, and the occasional material jamming and shortage during chain assembly, which seriously affect chain quality.

[0004] The above-mentioned technical problem of this utility model is solved by the following technical solution: a chain connecting piece assembly device with a safety device, including a machine tool, a transverse feeding groove on the machine tool, an assembly module on the machine tool, and a lower chain piece, a small tube, a sleeve, and an upper chain piece being assembled sequentially from the assembly module. The machine tool is characterized by: a connecting component assembly module, from which a lower connecting piece, a connecting pin, and an upper connecting piece are assembled sequentially; a feeding module for driving the chain assembly to move, and a first safety module on the feeding module; and a pushing mechanism corresponding to the assembly module and the connecting component assembly module on the rear side of the machine tool, with a second safety module on the pushing mechanism. During processing, the lower chain links, small tubes, sleeves, and upper chain links of the chain parts are sequentially produced from the assembly module and assembled. The lower chain links, small tubes, sleeves, and upper chain links are assembled into several chain components. Meanwhile, the lower connecting piece, connecting pin, and upper connecting piece are produced from the component assembly module. The lower chain links, small tubes, sleeves, and upper chain links connect adjacent chain components. The lower chain links, small tubes, sleeves, upper chain links, lower connecting pieces, connecting pins, and upper connecting pieces are assembled into a complete chain.

[0005] Preferably, the assembly module includes an assembly base block fixed to the machine tool feed end, with several assembly discharge ports on the assembly base block. A material box is mounted above the assembly base block, and an assembly material cylinder is provided between the material box and the assembly discharge ports. Chain parts are stored in sections in the material box, and the parts fall into the assembly base block along the assembly material cylinder. Under the action of the pushing mechanism, the parts are discharged into the conveying trough for assembly.

[0006] Preferably, the connecting component assembly module includes a first connecting platform that connects to the assembly module. The bottom of the first connecting platform has a lower connecting piece outlet, and the first connecting platform also has a connecting pin outlet groove. The lower connecting piece and the connecting pin are stored in the first connecting platform and are discharged into the conveying groove under the action of the pushing mechanism for assembly. The connecting pin and the lower connecting piece initially connect the chain component assembled from the lower chain piece, small tube, sleeve, and upper chain piece.

[0007] Preferably, the connecting pin discharge groove is mounted above the material trough, and a discharge hole is provided at the end of the connecting pin discharge groove. The connecting pin falls into the small tube from the discharge hole.

[0008] Preferably, the connecting component assembly module further includes a second connecting platform spaced apart from the first connecting platform, with an upper connecting piece outlet on its top side. The upper connecting piece is stored in the second connecting platform and is discharged for assembly under the action of a pushing mechanism.

[0009] Preferably, the feeding module includes a drive base plate slidably mounted on the machine tool, which is driven by a motor. The drive base plate has several clamping plates spaced apart, each with a slot corresponding to a chain component. The clamping slots of the clamping plates engage with the components, and the drive base plate then moves the components to the right.

[0010] Preferably, the first safety module includes two contact sliders slidably mounted on a plate, each contact slider corresponding to a part. Each contact slider has a contact stop bar. A safety block is fixedly mounted on the plate, energized, and located in front of the contact stop bar, with a gap between the safety block and the contact stop bar. The safety block is connected to the drive motor of the feeding module via a circuit. During processing, if a part is missing from the corresponding position, the contact stop bar will move backward, contacting and energizing the safety block. At this time, an electrical signal is sent to the drive motor of the feeding module, causing the drive motor to stop working and ensuring that no chain parts are missing.

[0011] Preferably, the first safety module further includes a fixed stop bar fixed to the card plate, and a first safety spring is provided between the fixed stop bar and the contact stop bar. During processing, if a part is missing at the corresponding position, the contact stop bar will move backward under the action of the first safety spring, and the contact stop bar will make contact with the safety block and be energized. At this time, an electrical signal is sent to the drive motor of the feeding module, and the drive motor stops working.

[0012] Preferably, the pushing mechanism includes several pushing drives fixed to the rear side of the machine tool, and each pushing drive is equipped with a pushing plate. The pushing plate pushes out the parts in the assembly module and the connecting component assembly module from the rear side for assembly.

[0013] Preferably, the second safety module includes a safety bar installed below the pusher plate. The safety bar moves back and forth with the pusher plate, and its tail end has an energized safety contact. The safety contact is connected to the drive motor of the feeding module via a circuit. A gap is left between the safety bar and the safety contact, and a second safety spring is provided between the safety bar and the safety contact. During assembly, the safety bar pushes the parts out with the pusher plate. When a part gets stuck, the safety bar moves backward and contacts the safety contact. Similarly, the drive motor stops working at this time, ensuring the continuity of chain assembly and preventing parts from being missing.

[0014] Therefore, the chain connecting piece assembly equipment with a safety device of this utility model has the following advantages: it can automatically produce and assemble chains, has high assembly efficiency, can be applied to the assembly of various irregularly shaped chains, greatly reduces the need for manual work, can meet higher production requirements, and can effectively avoid material jamming or shortage during chain assembly, ensuring the integrity of chain assembly.

The lower chain piece, small tube, sleeve, and upper chain piece are sequentially discharged from the assembly module for assembly.

[0027] The machine tool 1 is also equipped with a connecting component assembly module. The connecting component assembly module includes a first connecting platform 7 that connects to the assembly module. The bottom of the first connecting platform 7 is provided with a lower connecting piece outlet 8. Two connecting pin outlet grooves 9 are mounted on the first connecting platform 7. The connecting pin outlet grooves 9 are inclined grooves, and the ends of the connecting pin outlet grooves 9 are provided with outlet holes.

[0028] The connecting component assembly module also includes a second connecting platform 10 installed at a distance from the first connecting platform 7, and the top side of the second connecting platform 10 is provided with an upper connecting piece outlet 11.

[0029] The machine tool 1 is equipped with a feeding module for moving the chain assembly, and a first safety module is installed on the feeding module. The feeding module includes a drive base plate that is slidably installed on the front side of the machine tool 1. The drive base plate is driven by a motor. Several clamping plates 12 are installed at intervals on the drive base plate. The drive base plate drives the clamping plates 12 to move forward, backward, left and right in multiple directions. Each clamping plate 12 has a slot corresponding to the chain parts.

[0030] The first safety module includes two contact sliders 13 that are slidably mounted on the corresponding card plate 12 at the sleeve outlet. The contact sliders 13 can contact the parts. Each contact slider 13 has a contact stop bar 14 fixedly mounted at its rear end. A safety block 15 is fixedly mounted on the card plate 12 corresponding to the sleeve outlet. The safety block 15 is energized and is located in front of the contact stop bar 14. There is a gap between the safety block 15 and the contact stop bar 14. The safety block 15 is connected to the drive motor of the feeding module through a circuit.

[0031] The first safety module also includes a fixed stop bar 16 fixedly installed on the clamping plate 12 corresponding to the sleeve outlet, and a first safety spring 17 is installed between the fixed stop bar 16 and the contact stop bar 14.

[0033] The ejection mechanism includes several pusher drives fixedly installed on the rear side of the machine tool 1. Each pusher drive is equipped with a pusher plate 18, which extends into the assembly module and the connecting component assembly module.

[0034] The second safety module includes a safety rod 19 installed below the pusher plate 18.

The lower chain links, small tubes, sleeves, upper chain links, lower connecting pieces, connecting pins, and upper connecting pieces are assembled into a complete chain.

[0036] During processing, if a part is missing at the corresponding position, such as a small tube or a sleeve, the contact stop bar 14 will move backward under the action of the first safety spring 17. The contact stop bar 14 will then contact the safety block 15 and be electrically connected. At this time, an electrical signal is sent to the drive motor of the feeding module, and the drive motor stops working to ensure that no chain parts are missing.

[0037] During assembly and processing, the safety bar 19 pushes the parts out along with the pusher plate 18. When the parts get stuck, the safety bar 19 will move backward and contact the safety contact 20. Similarly, at this time, the drive motor stops working to ensure the continuity of chain assembly and that no parts are missing.
