Description

Technical Field

[0001] This utility model belongs to the field of chain processing technology, and more specifically, it relates to a chain four-corner riveting machine with detection function. Background Technology

[0002] As a key component in mechanical transmission and conveying, the chain's connection strength and the quality of its riveting heads directly determine its service life and operational safety. The chain four-corner riveting machine is a core piece of equipment in the chain production process. Existing chain four-corner riveting machines mainly consist of an upper die, a lower die, a riveting drive mechanism, and a chain drive mechanism. During operation, the riveting drive mechanism drives the upper die to press down, riveting the chain pins on the lower die; the upper die has four corner grooves that compress the pin ends to form four-corner riveting heads, achieving a secure connection between the chain links. Simultaneously, the chain drive mechanism, through multiple sets of pneumatic push rods, drives a toothed structure to mesh with the chain, propelling the chain smoothly within the lower die's conveying groove to complete continuous processing.

[0003] Existing application number CN201020243726.5 discloses a chain four-corner riveting machine, comprising: an upper beam, riveting mechanisms, a chain channel, guide posts, a machine frame worktable, a lower die, toothed plates, and a cross slide plate. The chain channel is positioned on the machine frame worktable, with guide posts at both ends. The upper beam is mounted on the guide posts and located directly above the chain channel. The lower die is positioned directly below the chain channel, with the upper beam and lower die corresponding vertically. A cross slide plate, capable of moving horizontally and vertically, is located on one side of the chain channel, and a toothed plate is mounted on the cross slide plate. Two riveting mechanisms are mounted on the upper beam, and two riveting mechanisms are also mounted inside the lower die. The chain four-corner riveting machine of this invention has high production efficiency and improves the riveting head qualification rate.

[0004] Based on the above, most existing chain corner riveting machines directly convey the chain out of the equipment after completing the riveting process. Whether the riveted corner structure meets dimensional specifications, conforms to standards, and whether there are any quality issues such as missing rivets all require subsequent inspection by staff. This not only increases the workload and inspection costs, but also, in high-volume continuous processing scenarios, manual inspection is prone to fatigue, leading to decreased efficiency, missed inspections, and misjudgments, thus affecting the overall production rhythm. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a chain corner riveting machine with inspection capabilities. This solves the problem that existing chain corner riveting machines mostly directly convey the chain out of the equipment after completing the riveting process. Whether the riveted corner structure meets dimensional specifications, conforms to standards, and has any quality issues such as missing rivets all require subsequent individual inspection by staff. This not only increases the workload and inspection costs, but also, in high-volume continuous processing scenarios, manual inspection is prone to fatigue, leading to decreased efficiency, missed inspections, and misjudgments, thus affecting the overall production rhythm.

[0006] The purpose and effectiveness of this utility model, a chain four-corner riveting machine with detection function, are achieved by the following specific technical means: A chain four-corner riveting machine with detection function includes a riveting body, a lower die body, a conveying guide rail, a drive mechanism, an upper beam body, an upper die body, a detection mechanism, a conveying mechanism, a dimension detection component, and a displacement detection component. The lower die body is fixedly connected to the upper part of the riveting body; the conveying guide rail is fixedly connected to the upper part of the lower die body; the drive mechanism is fixedly installed on the upper part of the riveting body; the upper beam body is fixedly installed on top of the drive mechanism; the upper die body is fixedly installed on the lower part of the upper beam body; the detection mechanism is fixedly installed on the upper part of the conveying guide rail; the conveying mechanism is installed on the upper part of the lower die body; the dimension detection component is disposed inside the detection mechanism; and the displacement detection component is disposed at the bottom of the detection mechanism.

[0007] Furthermore, the size detection component includes a drive block and a first rack, wherein the drive block is fixedly installed on the side of the upper mold body; and the first rack is vertically slidably connected inside the detection mechanism.

[0008] Furthermore, the size detection component also includes: a rotating shaft and an elastic coil spring, wherein the rotating shaft is rotatably connected inside the detection mechanism; one end of the elastic coil spring is fixedly connected to the outside of the rotating shaft, and the other end of the elastic coil spring is fixedly connected to the inside of the detection mechanism.

[0009] Furthermore, the size detection component also includes: a drive gear and a second rack, the drive gear being coaxially and fixedly connected to the middle of the rotating shaft, and the drive gear and the first rack meshing with each other; the second rack being vertically and slidably connected inside the detection mechanism, and the second rack and the drive gear meshing with each other.

[0010] Furthermore, the size detection component also includes: a detection rod, standard grooves, and contacts. The detection rod is fixedly connected to the end of the second rack. Multiple sets of standard grooves are provided, and the multiple sets of standard grooves are equidistantly provided at the bottom of the detection rod. The size of the standard grooves is fully adapted to the standard specifications of the four corner rivets. Multiple sets of contacts are provided, and every four sets of contacts are fixedly connected to the inner perimeter of a set of standard grooves.

[0011] Furthermore, the displacement detection component includes a displacement sensor and an elastic element. The displacement sensor is slidably connected to the bottom of the detection mechanism. One end of the elastic element is fixedly connected to the top of the displacement sensor, and the other end of the elastic element is fixedly connected inside the detection mechanism.

[0012] Furthermore, the displacement detection component also includes a movable roller, which is rotatably connected to the bottom of the displacement sensor.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Firstly, this utility model has a size detection component. Through a drive block linked to the upper mold body, the rack and pinion transmission is driven, and with the reset action of the elastic coil spring, the detection rod is automatically raised and lowered. During riveting, the detection rod is raised to avoid interfering with the chain conveying. After riveting, the detection rod moves down to make the standard groove accurately engage the rivet head. Then, by observing the contact state between the contact point in the groove and the rivet head, the size of the rivet head is judged in real time to determine whether it is compliant. There is no need for manual measurement, which greatly reduces the workload of manpower and avoids fatigue omissions in manual inspection, thus improving the accuracy and efficiency of rivet head size detection.

[0014] Secondly, this utility model has a displacement detection component, which provides a continuous preload to the displacement sensor through an elastic element, so that the bottom moving roller is tightly attached to the chain surface. When the chain is conveyed, the roller moves accordingly to reduce friction damage. The displacement sensor captures the undulation changes of the chain surface in real time. If there is a case of excessive rivet height or missing rivets, it can be quickly identified through abnormal displacement data. It complements the size detection component to realize full-dimensional detection of rivet quality and further ensure the chain processing quality.

[0015] This invention has the advantages of rapid detection, ease of use, and reduced manual intervention. It does not require additional independent detection procedures and can complete quality inspection simultaneously during chain riveting. This simplifies the production process, speeds up the production pace, reduces the flow of defective products, and lowers subsequent rework costs, making it suitable for the high-efficiency quality inspection needs of large-volume chain processing scenarios.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Example 1: As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a chain four-corner riveting machine with detection function, including a riveting body 1, a lower die body 2, a conveying guide rail 3, a drive mechanism 4, an upper beam body 5, an upper die body 6, a detection mechanism 7, a conveying mechanism 8, and a size detection component. The lower die body 2 is fixedly connected to the upper part of the riveting body 1; the conveying guide rail 3 is fixedly connected to the upper part of the lower die body 2; the drive mechanism 4 is fixedly installed on the upper part of the riveting body 1; the upper beam body 5 is fixedly installed on the top of the drive mechanism 4; the upper die body 6 is fixedly installed on the lower part of the upper beam body 5; the detection mechanism 7 is fixedly installed on the upper part of the conveying guide rail 3; the conveying mechanism 8 is installed on the upper part of the lower die body 2; and the size detection component is disposed inside the detection mechanism 7.

[0024] The size detection component includes a drive block 601 and a first rack 701. The drive block 601 is fixedly installed on the side of the upper mold body 6; the first rack 701 is vertically slidably connected inside the detection mechanism 7.

[0025] The dimension detection component also includes a rotating shaft 702 and an elastic coil spring 7022. The rotating shaft 702 is rotatably connected inside the detection mechanism 7. One end of the elastic coil spring 7022 is fixedly connected to the outside of the rotating shaft 702, and the other end of the elastic coil spring 7022 is fixedly connected inside the detection mechanism 7.

[0026] The size detection component also includes a drive gear 7021 and a second rack 703. The drive gear 7021 is coaxially fixedly connected to the middle of the rotating shaft 702, and the drive gear 7021 and the first rack 701 mesh with each other. The second rack 703 is vertically slidably connected inside the detection mechanism 7, and the second rack 703 and the drive gear 7021 mesh with each other.

[0027] The dimension detection component also includes: a detection rod 704, a standard groove 7041, and a contact 7042. The detection rod 704 is fixedly connected to the end of the second rack 703. Multiple sets of standard grooves 7041 are provided, and multiple sets of standard grooves 7041 are equidistantly provided at the bottom of the detection rod 704. The size of the standard grooves 7041 is fully compatible with the standard specifications of the four corner rivets. Multiple sets of contacts 7042 are provided, and every four sets of contacts 7042 are fixedly connected to the inner periphery of a set of standard grooves 7041.

[0028] The specific usage and function of this embodiment are as follows: First, the conveying mechanism 8 on the upper part of the lower mold body 2 is activated, driving the chain in the conveying guide rail 3 to move smoothly along the processing direction, so that the chain segment to be riveted is accurately conveyed to the upper mold body 2 corresponding to the upper mold body 6. Then, the drive mechanism 4 outputs power, driving the upper beam body 5 and the upper mold body 6 below it to move downward synchronously, and performing four-corner riveting operation on the conveyed chain pin shaft.

[0029] During the downward movement of the upper mold body 6, the drive block 601 fixed on its side moves synchronously with the upper mold and presses down on the first rack 701 inside the detection mechanism 7, causing the first rack 701 to slide vertically down along the guide structure inside the detection mechanism 7. As the first rack 701 slides down, it drives the drive gear 7021 to rotate around the rotating shaft 702 through tooth surface meshing. During the rotation of the rotating shaft 702, the elastic coil spring 7022 connected to its outer side is simultaneously contracted to store elastic potential energy. At the same time, the drive gear 7021 drives the second rack 703 to move vertically upward along the inside of the detection mechanism 7 through tooth surface meshing on the other side. The upward movement of the second rack 703 simultaneously drives the detection rod 704 at its end to rise, avoiding interference between the detection rod 704 and the conveying chain and ensuring smooth chain transmission.

[0030] After the chain riveting is completed, the drive mechanism 4 drives the upper beam body 5 and the upper mold body 6 to return to their original positions. At this time, the elastic coil spring 7022 in the detection mechanism 7 releases its stored elastic potential energy, causing the rotating shaft 702 to rotate in the opposite direction and reset. The rotating shaft 702, through the meshing transmission of the drive gear 7021 and the second rack 703, pulls the second rack 703 to move vertically downward, thereby driving the detection rod 704 to move downward synchronously. This causes the multiple sets of standard grooves 7041 at the bottom of the detection rod 704 to precisely engage with the outer side of the four corner rivets of the chain. Because the size of the standard grooves 7041 is perfectly matched with the standard specifications of the four corner rivets, the four sets of contacts 7042 on its inner perimeter can fully contact the surface of the rivet. If the rivet size meets the standard, the contacts 7042 can stably trigger the detection signal; if the rivet size exceeds the standard or is damaged, the contacts 7042 will show an abnormal signal. This detection signal can be transmitted to an externally connected computer in real time to visually present the rivet quality in the form of data or images, realizing automated detection of rivet specifications.

[0031] Example 2: Based on Example 1, such as Figures 1 to 5 As shown, it also includes a displacement detection component, which is located at the bottom of the detection mechanism 7.

[0032] The displacement detection component includes a displacement sensor 705 and an elastic element 7051. The displacement sensor 705 is slidably connected to the bottom of the detection mechanism 7. One end of the elastic element 7051 is fixedly connected to the top of the displacement sensor 705, and the other end of the elastic element 7051 is fixedly connected to the inside of the detection mechanism 7.

[0033] The displacement detection component also includes a movable roller 7052, which is rotatably connected to the bottom of the displacement sensor 705.

[0034] The specific usage and function of this embodiment are as follows: Before the equipment is put into operation, the displacement sensor 705 in the displacement detection assembly is always under the elastic support of the elastic element 7051, which keeps it under downward preload. This ensures that the movable roller 7052, which is rotatably connected to the bottom of the displacement sensor 705, fits tightly against the upper surface of the chain in the conveying guide rail 3, thus ensuring the stability of the initial detection state.

[0035] When the conveying mechanism 8 drives the chain to move along the conveying guide rail 3, the friction between the chain and the moving roller 7052 causes the moving roller 7052 to rotate synchronously. This rolling contact significantly reduces the frictional resistance during chain conveying, preventing scratch damage to the chain surface and ensuring the stability of the chain conveying trajectory. During this process, if the height of the chain pin after riveting meets the standard, the displacement sensor 705 will maintain the amplitude of the undulation of the upper surface of the chain within a preset range. If the rivet head is too convex or there is no rivet head at the corresponding position, resulting in a surface depression, the undulation distance of the upper surface of the chain will exceed the normal threshold. The displacement sensor 705 can capture this displacement change in real time and convert the detected displacement data into an electrical signal, which is transmitted to an externally connected computer. By comparing the data, the computer can intuitively determine whether the chain pin riveting height meets the standard and whether there is any missing riveting, further improving the all-dimensional detection of rivet head quality.

[0037] 2. Where there is no conflict, this embodiment and the features in the embodiment can be combined with each other to obtain new embodiments.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this embodiment should be included within the protection scope of this embodiment.
