Description

Technical Field

[0001] This utility model relates to the field of workpiece inspection, and in particular to a steel wire inspection machine. Background Technology

[0002] In the field of machinery manufacturing, the machining accuracy of small workpieces such as screws and bolts directly affects the assembly quality and operational stability of the entire machine, especially when machining small parts such as screws and bolts. Figure 2 As shown, the multi-segment workpiece makes precision inspection after machining a crucial step in ensuring product quality. These workpieces typically require comprehensive testing of multiple parameters, including thread accuracy, shank straightness, head flatness, and surface defects, to meet the stringent requirements of aerospace, high-end equipment, and other fields. However, due to the small size of the workpiece, specialized gripping fixtures are necessary for stable fixation during inspection to prevent errors caused by workpiece movement.

[0003] Most current mainstream gripping fixtures adopt clamping or adsorption structures. To ensure gripping stability, the fixture often needs to cover more than 60% of the workpiece surface area, which can easily cause obstruction, especially in critical inspection areas such as threaded sections and heads. This means that only a portion of the surface parameters can be collected in a single inspection. To obtain complete inspection data, the workpiece must be flipped multiple times by a robotic arm or manually, the clamping position adjusted, and the inspection process repeated. This operating mode not only prolongs the inspection cycle and reduces production efficiency, but may also cause minor deformation or surface scratches to the workpiece due to repeated clamping. At the same time, the cumulative error of multiple positioning will also affect the inspection accuracy, making it difficult to meet the high-efficiency and precision inspection requirements of large-scale production. Utility Model Content

[0004] To improve the convenience and intuitiveness of workpiece inspection, this utility model provides a steel wire inspection machine.

[0005] This utility model provides a technical solution that adopts the following approach:

[0006] A wire inspection machine includes an inspection component, a feeding component, a conveying component, and a discharging component. The conveying component includes two metal wires for transmission. The two metal wires move from the feeding component to the discharging component. The two metal wires are parallel to each other, and the distance between the two metal wires is less than the diameter of the smallest part of the workpiece. The metal wires are horizontally arranged and are in a taut state. The inspection component is located between the feeding component and the discharging component.

[0007] The feeding assembly places the workpiece on two metal wires. The larger diameter portion of the workpiece restricts its descent, suspending it between the two wires. The wire diameter is smaller than the minimum diameter of the workpiece, allowing the two wires to carry the workpiece synchronously along their length, thus moving it from the feeding assembly to the unloading assembly. During this transfer, the detection assembly inspects the workpiece on the wires. The volume of the part of the wire in contact with the workpiece is much smaller than the workpiece's volume, thus greatly reducing obstruction and impact on the workpiece during inspection. This makes the processing status of each part of the workpiece more intuitive and easier to inspect.

[0008] Preferably, the conveying assembly further includes two sets of conveying disks and a drive motor, the end of the metal wire is closed and sleeved on the periphery of one set of conveying disks, and the drive motor drives the conveying disks to rotate.

[0009] Two metal wires are looped around the perimeter of two sets of conveyor discs. The workpiece is placed on the metal wires on the side of the two sets of conveyor discs that are close to each other. The conveyor discs drive the metal wires to reciprocate, and at the same time, they can flex the metal wires.

[0010] Preferably, the peripheral wall of the conveyor disc has an annular limiting groove for embedding metal wires.

[0011] The setting of the limiting groove allows the metal wire to be securely sleeved on the peripheral wall of the conveyor plate, which helps to improve the stability of the metal wire conveyed by the metal plate, thereby improving the stability of the workpiece movement. In addition, supporting multiple workpieces requires a certain amount of support force, and the limiting groove allows the metal wire to support multiple workpieces more securely.

[0012] Preferably, the conveyor trays are inclined, and the conveyor trays in the same group extend downward from one end that is close to the other end that is far away from the other.

[0013] The conveyor plate is tilted so that the opening of the limiting groove used to support the metal wires that are close to each other faces upward, which can more stably support the metal wires and prevent the metal wires from falling out of the limiting groove.

[0014] Preferably, the detection assembly includes a plurality of detection parts and a support frame for supporting the detection parts. The plurality of detection parts are evenly distributed along the length direction of the metal wire. The plurality of detection parts are set with an adaptive tilt angle corresponding to the direction of the feature to be detected. The support frame extends to a position close to the workpiece.

[0015] The multi-directional detection unit can simultaneously collect various parameters, meeting the needs of efficient and precise detection in large-scale production. Moreover, the tilted design means that after fixing the detection unit at a certain angle, it is not necessary to rotate it again to detect the relevant parameters of the workpiece, which helps to improve the efficiency and quality of detection.

[0016] Preferably, the distance between the support frame and the portion of the metal wires that are close to each other is adjustable.

[0017] In this embodiment, a height adjustment component or a horizontal position adjustment structure can be provided to adjust the distance between the detection unit on the support frame and the workpiece on the wire, enabling the inspection machine to adapt to the inspection of workpieces of various models and sizes. The height adjustment component can be set as a guide rail slider structure in the vertical direction, and the horizontal position adjustment component can be set as a guide rail slider structure in the horizontal direction, thereby adjusting the position of the detection unit.

[0018] Preferably, the conveying assembly further includes a wire guide frame, which is disposed between the feeding assembly and the unloading assembly. The wire guide frame is disposed on one side of the two metal wires that are far apart from each other. The wire guide frame has a wire groove, which supports the metal wires.

[0019] The wire support bracket supports the side of the metal wire that is not in contact with the workpiece, avoiding the workpiece, while supporting the metal wire on the side where the opening of the limiting groove faces downwards. This makes the metal wire more securely set on the outer periphery of the conveyor plate, reducing the possibility of the outer ring of the metal wire falling out of the limiting groove and causing separation.

[0020] Preferably, the feeding assembly includes a vibrating feeding plate and a conveyor frame. The discharge end of the vibrating feeding plate is higher than the horizontal plane where the metal wire is located. The conveyor frame is located between the conveyor plate and the vibrating feeding plate. The conveyor frame has a sliding groove through which the workpiece slides. The sliding groove is inclined downward from the end of the vibrating feeding plate toward the junction of the ends of the two metal wires.

[0021] The conveyor frame significantly reduces the distance between the vibrating feeder and the conveying components, allowing the workpiece to fall smoothly between the two metal wires, which helps improve the stability of the feeding process.

[0022] In summary, this utility model has the following beneficial technical effects:

[0023] The feeding assembly places the workpiece on two metal wires. The larger diameter portion of the workpiece restricts its descent, suspending it between the two wires. The wire diameter is smaller than the minimum diameter of the workpiece, allowing the two wires to carry the workpiece synchronously along their length, thus moving it from the feeding assembly to the unloading assembly. During this transfer, the detection assembly inspects the workpiece on the wires. The volume of the part of the wire in contact with the workpiece is much smaller than the workpiece's volume, thus greatly reducing obstruction and impact on the workpiece during inspection. This makes the processing status of each part of the workpiece more intuitive and easier to inspect. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1 as well as Figure 2 This utility model will be described in further detail.

[0028] This utility model discloses a steel wire inspection machine.

[0029] Reference Figure 1 as well as Figure 2 A steel wire inspection machine includes an inspection component, a feeding component, a conveying component, and a discharging component. The conveying component includes two metal wires 1 for transmission. The two metal wires 1 move from the feeding component to the discharging component. The two metal wires 1 are parallel to each other. The distance between the two metal wires 1 is less than the diameter of the smallest part of the workpiece 2. The metal wires 1 are set horizontally and are in a taut state. The inspection component is set between the feeding component and the discharging component.

[0030] The feeding assembly places the workpiece 2 on two metal wires 1. The larger diameter portion of the workpiece 2 restricts its downward movement, causing it to suspend between the two metal wires 1. The diameter of the metal wires 1 is smaller than the minimum diameter of the workpiece 2, allowing the two metal wires 1 to carry the workpiece 2 and move synchronously along the length of the wires 1, thus moving it from the feeding assembly to the unloading assembly. During the transfer, the detection assembly detects the workpiece 2 on the metal wires 1. The volume of the part of the metal wire 1 in contact with the workpiece 2 is much smaller than the volume of the workpiece 2, thus greatly reducing the obstruction and impact on the workpiece 2 during detection. This makes the processing status of the workpiece 2 more intuitive and easier to detect.

[0031] Reference Figure 1 as well as Figure 2 In this embodiment, the conveying assembly also includes two sets of conveying disks 3 and a drive motor. The end of the metal wire 1 is closed and sleeved on the periphery of one set of conveying disks 3, and the drive motor drives the conveying disks 3 to rotate.

[0032] Two metal wires 1 are sleeved on the peripheral walls of two sets of conveyor discs 3. The workpiece 2 is placed on the metal wires 1 on the side of the two sets of conveyor discs 3 that are close to each other. The conveyor discs 3 drive the metal wires 1 to reciprocate, and at the same time can straighten the metal wires 1.

[0033] Reference Figure 1 as well as Figure 2In this embodiment, the peripheral wall of the conveyor disk 3 has an annular limiting groove 5 for embedding the metal wire 1.

[0034] The setting of the limiting groove 5 makes the metal wire 1 securely sleeved on the peripheral wall of the conveyor plate 3, which helps to improve the stability of the metal plate conveying the metal wire 1, thereby improving the stability of the movement of the workpiece 2. In addition, supporting multiple workpieces requires a certain supporting force, and the limiting groove 5 makes the metal wire 1 more securely support multiple workpieces 2.

[0035] Reference Figure 1 as well as Figure 2 In this embodiment, the conveyor disk 3 is inclined, and the conveyor disks 3 in the same group extend downward from the end that is close to each other to the end that is far away from each other.

[0036] The conveyor plate 3 is tilted so that the opening of the limiting groove 5, which is used to support the metal wires 1 that are close to each other, faces upward, thereby supporting the metal wires 1 more stably and preventing the metal wires 1 from falling out of the limiting groove 5.

[0037] Reference Figure 1 as well as Figure 2 In this embodiment, the detection assembly includes multiple detection units 7 and a support frame 6 for supporting the detection units 7. The multiple detection units 7 are evenly distributed along the length direction of the metal wire 1. The multiple detection units 7 are set with an adaptive tilt angle corresponding to the direction of the feature to be detected. The support frame 6 extends to a position close to the workpiece 2.

[0038] The multi-directional detection unit 7 can simultaneously collect various parameters, meeting the needs of efficient and precise detection in large-scale production. Moreover, the tilted setting means that after fixing the detection unit 7 at a certain angle, it is not necessary to continue to rotate it, and the relevant parameters of the workpiece 2 can be detected without rotating the workpiece 2, which helps to improve the efficiency and quality of detection.

[0039] Reference Figure 1 as well as Figure 2 In this embodiment, the distance between the support frame 6 and the metal wire 1 at their close proximity is adjustable.

[0040] In this embodiment, a height adjustment component or a horizontal position adjustment structure can be provided to adjust the distance between the detection part 7 on the support frame 6 and the workpiece 2 on the wire 1, so that the inspection machine can adapt to the inspection of workpieces 2 of various models and sizes. The height adjustment component can be set as a guide rail slider structure in the vertical direction, and the horizontal position adjustment component can be set as a guide rail slider structure in the horizontal direction, thereby adjusting the position of the detection part 7.

[0041] Reference Figure 1 as well as Figure 2In this embodiment, the conveying component also includes a wire guide frame 8, which is located between the feeding component and the unloading component. The wire guide frame 8 is located on the side where the two metal wires 1 are far apart from each other. The wire guide frame 8 has a wire groove 9, which supports the metal wires 1.

[0042] The wire support frame 8 supports the side of the metal wire 1 that is not in contact with the workpiece 2, avoiding the workpiece 2, and at the same time supports the metal wire 1 on the side of the opening of the limiting groove 5 facing downward, so that the metal wire 1 is more firmly set on the outer periphery of the conveyor plate 3, reducing the possibility of the outer ring of the metal wire 1 falling out of the limiting groove 5 and causing separation.

[0043] Reference Figure 1 as well as Figure 2 In this embodiment, the feeding assembly includes a vibrating feeding plate 10 and a conveyor frame 11. The discharge end of the vibrating feeding plate 10 is higher than the horizontal plane where the metal wire 1 is located. The conveyor frame 11 is located between the conveyor plate 3 and the vibrating feeding plate 10. The conveyor frame 11 has a sliding groove 12 through which the workpiece 2 slides. The sliding groove 12 is inclined downward from the end of the vibrating feeding plate 10 toward the junction of the ends of the two metal wires 1.

[0044] The conveyor frame 11 significantly reduces the distance between the vibrating feeder 10 and the conveying assembly, allowing the workpiece 2 to fall smoothly between the two metal wires 1, which helps improve the stability of the feeding. The structure of the vibrating feeder 10 applied to the workpiece 2 is existing technology and will not be described in detail here.

[0045] The unloading component is a structure set at the tail end of the conveying component to receive the workpiece 2. It can be set as a simple receiving trough or as a material distribution trough, and corresponding push arms are set to push workpieces 2 of different masses into different troughs for differentiation.

[0046] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
