Description

Technical Field

[0001] The invention relates to the technical field of parts processing, in particular to an elastic bending parts processing device. Background Art

[0002] In the field of sheet metal processing, the clamping and deformation detection technology of elastic bending workpieces faces multiple challenges. Elastic bending workpieces are prone to deformation due to material characteristics during stamping and punching, which affects the accuracy of workpiece processing. The existing process has the following technical bottlenecks: 1. Insufficient control of the rebound effect of elastic materials; Elastic materials (such as cold-rolled steel plates and memory alloys) are prone to rebound after bending due to internal stress in the material, and traditional mechanical clamping devices are difficult to compensate for this deformation. Hot-rolled steel plates and other materials are more likely to cause angle deviation accumulation during the clamping process due to surface oxide layers and internal structural inhomogeneities, affecting processing accuracy.

[0003] 2. Lack of composite deformation detection methods; In the existing technology, workpiece processing and deformation detection are independent processes. The deformation is evaluated by a three-point bending test, and the torsion resistance is tested separately by a torsion testing machine. This discrete detection mode cannot achieve real-time monitoring during the processing, resulting in delayed quality feedback.

[0004] 3. Low intelligence level of adaptive clamping system Traditional clamping devices still rely on fixed fixtures (such as bolt-positioned mechanical clamps), and adjusting the clamping position requires disassembly and reassembly, which is time-consuming and prone to human errors.

[0005] In order to solve the above problems, the present application provides an elastic bending parts processing device, which is used to clamp and detect bending workpieces with a certain elasticity, improve the fixing efficiency of mechanical workpieces, and ensure processing efficiency. Summary of the invention

The detection part includes a plurality of first detection rods, and the plurality of first detection rods are evenly distributed along the width direction of the workpiece.

[0008] As an optimization, the two clamping parts are respectively a first clamping part and a second clamping part, the second clamping part is located on the upper side of the first clamping part, and the first clamping part and the second clamping part are respectively used to clamp the two ends of the bent workpiece.

[0009] As an optimization, the clamping assembly includes a connecting seat, two second telescopic rods and a clamping plate connected to the outer ends of the second telescopic rods, the second telescopic rods are connected between the connecting seat and the clamping plate, the connecting seat can move along the length direction of the adjustment seat, and the two clamping plates are respectively located on both sides of the workpiece.

DETAILED DESCRIPTION

[0023] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0024] like Figure 1 As shown, the elastic bending part processing device is used for positioning and clamping the bending workpiece, including a detection part and a clamping part for clamping the two ends of the workpiece, the clamping part includes a fixed seat 1, a first telescopic rod 2, an adjustment seat 3 and two clamping components, the first telescopic rod 2 is used to drive the adjustment seat 3 to move in a direction parallel to the end of the workpiece, and the two clamping components can move along the length direction of the adjustment seat 3; The detection part is arranged at the lower side of the bending part of the workpiece, and is used to detect the torsion and deformation of the workpiece. The detection part includes a plurality of first detection rods 4, and the plurality of first detection rods 4 are evenly distributed along the width direction of the workpiece.

[0025] The two clamping parts are used to clamp the two ends of the bending workpiece respectively. The clamping parts can adapt to the clamping needs of workpieces of different widths and lengths. When clamping, the clamping assembly is connected to the edge of the workpiece without affecting operations such as opening and stamping of the workpiece.

[0026] Since the bending part of the workpiece generally has a certain elasticity, the two ends of the workpiece are easy to twist in the same or opposite directions, causing the workpiece to deform. When one end of the workpiece is clamped and fixed, the bending part of the workpiece is inspected by the detection part to determine whether the workpiece needs to be corrected.

[0027] like Figure 1 As shown, the two clamping parts are respectively a first clamping part and a second clamping part, the second clamping part is located on the upper side of the first clamping part, and the first clamping part and the second clamping part are respectively used to clamp the two ends of the bent workpiece.

[0028] The clamping assembly includes a connecting seat 5, two second telescopic rods 6 and a clamping plate 7 connected to the outer end of the second telescopic rod 6, the second telescopic rod 6 is connected between the connecting seat 5 and the clamping plate 7, the connecting seat 5 can move along the length direction of the adjustment seat 3, and the two clamping plates 7 are respectively located on both sides of the workpiece.

[0029] The fixed ends of the two second telescopic rods 6 are fixedly connected to the connecting seat 5, so that one of the second telescopic rods 6 is located at the lower side of the workpiece, and the other second telescopic rod 6 is located at the outside of the workpiece. When the outer second telescopic rod 6 is extended, a clamping space is formed between the two clamping plates 7, which is convenient for placing the workpiece into the clamping space for clamping.

[0030] The clamping plate 7 is L-shaped and is disposed along two adjacent edges of the workpiece, so that the clamping plate 7 can stably clamp the edge of the workpiece without affecting the processing operation of the workpiece.

[0031] like Figure 1 and Figure 2 As shown, the second clamping part is provided with a second detection part, the second detection part comprises a third telescopic rod 8 and a plurality of second detection rods 9, the second detection rod 9 has the same structure as the first detection rod 4, and the third telescopic rod 8 is used to push the second detection part to move toward the workpiece; The second detection portion is disposed between two groups of clamping assemblies of the second clamping portion, and the third telescopic rod 8 is disposed parallel to the second telescopic rod 6 of the clamping assembly.

[0032] When the upper end of the workpiece is clamped, the upper end of the workpiece is located between the two clamping plates 7 of the second clamping part. The second detection part detects whether the distance between the workpiece and the adjustment seat 3 is the same. If the distances detected by the multiple second detection rods 9 are the same, it indicates that the workpiece has not been twisted. According to the size of the workpiece, the fixed extension distance of the third telescopic rod 8 can be set. If the values ​​detected by the multiple second detection rods 9 are the same when the extension distance is fixed, it means that the upper part of the surface workpiece has not been deflected. If the second detection rod 9 does not contact the workpiece after the third telescopic rod 8 is extended to the fixed extension distance, it indicates that the upper part of the workpiece has been deflected and the workpiece needs to be corrected.

[0033] like Figure 1 As shown, the adjustment seat 3 is provided with an adjustment slot 10 , and a driving screw is disposed inside the adjustment slot 10 . The driving screw is used to drive the clamping assembly to move, and a driving motor 11 is connected to the end of the driving screw.

[0034] The driving motor 11 is used to drive the driving screw rod. The driving screw rod and the driving motor 11 can also be replaced by other devices that can stably move the clamping assembly.

[0035] like Figure 6 and Figure 7 As shown, the first detection rod 4 includes a fixed rod 12 and a movable rod 13, one end of the movable rod 13 is slidably arranged inside the fixed rod 12, a supporting spring 14 for supporting the movable rod 13 is arranged inside the fixed rod 12, and a ball 15 is rotatably connected to the outer end of the movable rod 13; A distance sensor 16 is disposed inside the fixed rod 12 , and a detection end of the distance sensor 16 is disposed toward the movable rod 13 .

[0036] When the movable rod 13 contacts the workpiece, the distance sensor 16 is used to detect the retracted length of the movable rod 13. When the retracted lengths of the movable rods 13 of the plurality of first detection rods 4 are the same, the workpiece does not undergo deformation such as concavity, convexity or twisting in this direction.

[0037] like Figure 4 As shown, the clamping plate 7 of the second clamping part is provided with an electromagnet 17, and the electromagnet 17 is arranged toward the upper part of the workpiece. When the workpiece is twisted or deformed, the electromagnet 17 attracts the workpiece so that the upper part of the workpiece is quickly positioned for easy clamping.

[0038] When the electromagnet 17 is energized, the upper part of the workpiece can be quickly magnetically sucked outward, so that the workpiece fits on the clamping plate 7, which can effectively counteract the material rigidity of the elastic workpiece and facilitate clamping of the workpiece. This process does not require manual resetting of the workpiece.

[0039] Directions: When the device is used, firstly, the distance between the two clamping components is adjusted by the driving motor 11 according to the width of the workpiece; The clamping assembly of the first clamping part is opened, the second telescopic rod 6 located on the outside is higher than the second telescopic rod 6 located on the inside, the two clamping plates 7 are arranged opposite to each other up and down, one end of the workpiece is horizontally extended between the two clamping plates 7, the second telescopic rod 6 is shortened, and the two clamping plates 7 clamp one end of the workpiece; The clamping assembly of the second clamping part is opened so that the upper part of the workpiece is located between the two clamping plates 7 of the clamping assembly; The bending part of the workpiece is detected by the first detection part, and the extension length of the movable rod 13 is detected by the distance sensor 16 to determine whether the bending part of the workpiece is deformed and twisted. When the extension length of the first detection rod 4 is different, the surface workpiece is twisted; The third telescopic rod 8 is extended, and the upper part of the workpiece is positioned and detected through a plurality of second detection rods 9 to determine the position of the upper part of the workpiece. When the extension lengths of the second detection rods 9 are different, it indicates that the workpiece is twisted or deformed; When the extension lengths of the first detection rod 4 are the same and the extension lengths of the second detection rod 9 are different, the upper part of the surface workpiece is deformed inward or outward, whether it is torsion or deformation, and the workpiece needs to be corrected after the workpiece is processed; The electromagnet 17 is energized to attract the workpiece, so that the upper part of the workpiece is quickly fitted with the clamping plate 7, the second telescopic rod 6 is shortened, the workpiece is clamped by the two clamping plates 7, and the upper part of the workpiece is pulled to the standard position; The workpiece is subjected to operations such as drilling and punching. After the processing is completed, the first clamping part and the second clamping part release the workpiece, and the workpiece can be removed.

[0040] If the edge of the workpiece is clamped and pushed outward by the clamping assembly, the edge of the workpiece is likely to deform, causing secondary damage to the workpiece and affecting the accuracy of the processing. By magnetically attracting the workpiece, the upper part of the workpiece can be evenly flipped outward, so that the upper part of the workpiece is evenly stressed, and then the upper part of the workpiece is pressed and positioned by the clamping assembly to ensure that the workpiece is evenly stressed.

The patent protection scope of the present invention includes but is not limited to the product form and style of the above-mentioned specific embodiments. Any elastic bending parts processing device that complies with the claims of the present invention and any appropriate changes or modifications made thereto by ordinary technicians in any corresponding technical field shall fall within the patent protection scope of the present invention.
