Description

Technical Field

[0001] This invention belongs to the field of automation equipment technology and relates to a gripping mechanism for complex-shaped stamped parts. Background Technology

[0002] During the production process, the lower corner hinge frame bracket needs to be gripped by a gripping mechanism. As a complex-shaped stamped part, the existing gripping mechanism for complex-shaped stamped parts has difficulty in limiting the lower corner hinge frame bracket to the center when gripping it. Its gripping accuracy is poor and its stability is average.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, Chinese patent discloses a lower support gripping robot [application number: 201811265183.4], which includes an electrical control box and a robotic arm. The electrical control box is equipped with a conveyor belt, and a PLC and a rotary motor and a servo motor connected to the PLC are installed inside the electrical control box. The robotic arm includes a base, which is located inside the electrical control box. Several rotating arms are connected to the base in sequence. Each rotating arm has a rotating shaft, and a suction cup is installed on the rotating shaft. The suction cup is connected to the PLC. A cylinder is also installed on the base, and the cylinder is connected to the PLC. A support is provided on the cylinder, and a positioning plate is provided on the support. An infrared sensor is provided on one side of the conveyor belt at the center position corresponding to the positioning plate. A positioning baffle is provided on one side of the support, and a top plate is provided on the positioning baffle. The top plate corresponds to the suction cup and the support, and several positioning pins are provided on the side of the top plate corresponding to the support. However, this solution is still not compatible with the lower corner hinge frame bracket during the gripping process. When gripping, it is still difficult to limit the lower corner hinge frame bracket to the center for gripping, resulting in poor gripping accuracy and relatively poor stability. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a gripping mechanism for stamped parts with complex shapes.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions:

[0006] A gripping mechanism for a complex-shaped stamped part includes a gripping and limiting base, a drive fixing plate on the gripping and limiting base, a lower corner hinge frame bracket limiting fixing assembly that can reciprocate linearly in the vertical direction below the drive fixing plate, a lifting drive component on the drive fixing plate, and the lifting drive component being connected to the lower corner hinge frame bracket limiting fixing assembly.

[0007] In the aforementioned gripping mechanism for a complex-shaped stamped part, the lower corner hinge frame bracket limiting and fixing assembly includes a lower corner hinge frame bracket limiting block disposed below the drive fixing plate. The lower corner hinge frame bracket limiting block has a lower corner hinge frame bracket snap-fit ​​component at its bottom, and the lower corner hinge frame bracket snap-fit ​​component is integrally formed with the lower corner hinge frame bracket limiting block.

[0008] In the aforementioned gripping mechanism for a complex-shaped stamped part, the lower corner hinge frame bracket clamping component includes two bracket clamping plates disposed at the bottom of the lower corner hinge frame bracket limiting block, and a rod seat alignment chamber is formed between two adjacent bracket clamping plates. The bracket clamping plates are provided with clamping interfaces.

[0009] In the aforementioned gripping mechanism for a complex-shaped stamped part, the clamping interface includes a clamping opening disposed within the bracket clamping plate, the clamping opening facing downwards, and the bracket clamping plate and the lower corner hinge frame bracket limiting block are integrally formed.

[0010] In the aforementioned gripping mechanism for a complex-shaped stamped part, a pivot alignment component is also provided at the bottom of the lower corner hinge frame bracket limiting block. The pivot alignment component is integrally formed with the lower corner hinge frame bracket limiting block, and the pivot alignment component and the bracket clamping plate are alternately arranged.

[0011] In the aforementioned gripping mechanism for a complex-shaped stamped part, the pivot alignment component includes a pivot alignment block disposed at the bottom of the lower corner hinge frame bracket limiting block. The pivot alignment block has an anti-interference opening facing downwards. The pivot alignment block and the lower corner hinge frame bracket limiting block are integrally formed. The pivot alignment block and the bracket clamping plate are staggered.

[0012] In the aforementioned gripping mechanism for a complex-shaped stamped part, the lifting drive component includes a cylinder mounted on a drive fixed plate, and a lifting connecting slide frame is mounted on the power shaft of the cylinder. The lifting connecting slide frame is connected to a limiting block of the lower corner hinge frame bracket.

[0013] In the aforementioned gripping mechanism for a complex-shaped stamped part, the gripping and limiting base is provided with a sliding plate limiting bracket, and the lifting connecting sliding plate frame passes through the sliding plate limiting bracket and slides in cooperation with the sliding plate limiting bracket.

[0014] In the aforementioned gripping mechanism for a complex-shaped stamped part, the lifting connecting slide frame is provided with a rod abutment, which is staggered with the lower corner hinge frame bracket limiting block.

[0015] In the aforementioned gripping mechanism for a complex-shaped stamped part, the insert rod abutting member includes an insert rod abutting block disposed on a lifting connecting slide frame. The insert rod abutting block and the lower corner hinge frame bracket limiting block are staggered. The insert rod abutting block and the lower corner hinge frame bracket limiting block are respectively connected to the lifting connecting slide frame by fastening bolts.

[0016] Compared with existing technologies, the advantages of this invention are:

[0017] 1. When gripping the lower corner hinge frame bracket, this invention places the lower corner hinge frame bracket below the lower corner hinge frame bracket limiting and fixing component. At this time, the lifting drive is activated, which drives the lower corner hinge frame bracket limiting and fixing component to descend. The lower corner hinge frame bracket is limited by the lower corner hinge frame bracket limiting and fixing component, ensuring that the lower corner hinge frame bracket is completely limited to the center. The limiting accuracy and automation are high, the structure is simple, and the stability is reliable.

[0018] 2. This invention uses a pivot alignment block to align the pivot of the lower corner hinge frame bracket. The anti-interference opening can prevent collisions with other structures of the lower corner hinge frame bracket. The shape is well-matched to prevent collision interference. The pivot alignment block and the lower corner hinge frame bracket limiting block are integrally formed, resulting in high strength and long service life.

[0019] 3. When limiting the lower corner hinge frame bracket, the present invention uses the insert rod abutment block to abut and position the insert rod structure of the lower corner hinge frame bracket, preventing the insert rod structure of the lower corner hinge frame bracket from tilting upwards during the limiting process. The overall limiting accuracy is higher and more precise. The insert rod abutment block and the lower corner hinge frame bracket limiting block are respectively connected to the lifting connecting slide frame by fastening bolts, which is simple and convenient to disassemble and assemble, and facilitates maintenance and replacement by staff.

[0020] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, a gripping mechanism for a complex-shaped stamped part includes a gripping and limiting base 1. The gripping and limiting base 1 is provided with a drive fixing plate 2. Below the drive fixing plate 2, there is a lower corner hinge frame bracket limiting and fixing assembly 3 that can reciprocate linearly in the vertical direction. The drive fixing plate 2 is provided with a lifting drive 4, and the lifting drive 4 is connected to the lower corner hinge frame bracket limiting and fixing assembly 3.

[0028] In this embodiment, when gripping the lower corner hinge frame bracket, the lower corner hinge frame bracket is placed below the lower corner hinge frame bracket limiting and fixing component 3. At this time, the lifting drive component 4 is activated, which drives the lower corner hinge frame bracket limiting and fixing component 3 to descend. The lower corner hinge frame bracket is limited by the lower corner hinge frame bracket limiting and fixing component 3, ensuring that the lower corner hinge frame bracket is completely limited to the center. The limiting accuracy and automation are high, the structure is simple, and the stability is reliable.

[0029] Combination Figure 1-4 As shown, the lower corner hinge frame bracket limiting and fixing assembly 3 includes a lower corner hinge frame bracket limiting block 5 disposed below the drive fixing plate 2. The lower corner hinge frame bracket limiting block 5 has a lower corner hinge frame bracket snap-fit ​​6 at its bottom. The lower corner hinge frame bracket snap-fit ​​6 is integrally formed with the lower corner hinge frame bracket limiting block 5.

[0030] Specifically, when gripping the lower corner hinge frame bracket, the lower corner hinge frame bracket is placed below the lower corner hinge frame bracket limiting block 5. At this time, the lifting drive component 4 is activated, which drives the lower corner hinge frame bracket limiting block 5 to descend. The lower corner hinge frame bracket is limited by the lower corner hinge frame bracket locking component 6 on the lower corner hinge frame bracket limiting block 5, ensuring that the lower corner hinge frame bracket is completely limited in the center. The limiting accuracy and automation are high, the structure is simple, and the stability is reliable. The lower corner hinge frame bracket locking component 6 is integrally formed with the lower corner hinge frame bracket limiting block 5, which has high strength and long service life.

[0031] Combination Figure 1 , Figure 3 As shown, the lower corner hinge frame bracket snap-fit ​​component 6 includes two bracket snap-fit ​​clamps 7 disposed at the bottom of the lower corner hinge frame bracket limiting block 5, and a rod seat alignment chamber 8 is formed between two adjacent bracket snap-fit ​​clamps 7. The bracket snap-fit ​​clamps 7 are provided with snap-fit ​​interface portions 9.

[0032] In this embodiment, when gripping the lower corner hinge frame bracket, the lower corner hinge frame bracket is placed below the lower corner hinge frame bracket limiting block 5. At this time, the lifting drive 4 is activated, which drives the lower corner hinge frame bracket limiting block 5 to descend. The bracket locking clamp 7 on the lower corner hinge frame bracket limiting block 5 limits the lower corner hinge frame bracket. The locking interface 9 facilitates the locking and fixing of the lower corner hinge frame bracket, allowing the insertion rod seat of the lower corner hinge frame bracket to enter the insertion rod seat alignment chamber 8, ensuring that the lower corner hinge frame bracket is completely limited in the center. The limiting accuracy and automation are high, the structure is simple, and the stability is reliable. The lower corner hinge frame bracket locking part 6 is integrally formed with the lower corner hinge frame bracket limiting block 5, which has high strength and long service life.

[0033] The card interface portion 9 includes a card opening 10 disposed in the bracket card clamping plate 7, the card opening 10 facing downwards, and the bracket card clamping plate 7 and the lower corner hinge frame bracket limiting block 5 are integrally formed.

[0034] In this embodiment, the snap-fit ​​opening 10 facilitates the snap-fit ​​fixing of the lower corner hinge frame bracket. The bracket snap-fit ​​clamp 7 and the lower corner hinge frame bracket limiting block 5 are integrally formed, resulting in high strength and long service life.

[0035] Combination Figure 1 , Figure 3 As shown, the bottom of the lower corner hinge frame bracket limiting block 5 is also provided with a rotating shaft alignment component 11. The rotating shaft alignment component 11 is integrally formed with the lower corner hinge frame bracket limiting block 5, and the rotating shaft alignment component 11 and the bracket clamping plate 7 are alternately arranged.

[0036] In this embodiment, the pivot alignment member 11 is used to align the pivot of the lower corner hinge frame bracket.

[0037] The pivot alignment component 11 includes a pivot alignment block 12 disposed at the bottom of the lower corner hinge frame bracket limiting block 5. The pivot alignment block 12 is provided with an anti-interference opening 13, which faces downward. The pivot alignment block 12 and the lower corner hinge frame bracket limiting block 5 are integrally formed. The pivot alignment block 12 and the bracket snap-fit ​​clamp 7 are staggered.

[0038] In this embodiment, the pivot alignment block 12 is used to align the pivot of the lower corner hinge frame bracket. The anti-interference opening 13 can avoid collision with other structures of the lower corner hinge frame bracket. The shape is suitable to prevent collision interference. The pivot alignment block 12 and the lower corner hinge frame bracket limiting block 5 are integrally formed, with high strength and long service life.

[0039] The lifting drive component 4 includes a cylinder 133 mounted on the drive fixed plate 2. The power shaft of the cylinder 133 is provided with a lifting connecting slide frame 14, which is connected to the lower corner hinge frame bracket limiting block 5.

[0040] In this embodiment, when it is necessary to raise or lower the lower corner hinge frame bracket limit block 5, the cylinder 133 is activated, and the power shaft of the cylinder 133 drives the lifting connecting slide frame 14 and the lower corner hinge frame bracket limit block 5 to rise or fall, which has a high degree of automation.

[0041] Combination Figure 1-2 As shown, the gripping and limiting machine base 1 is provided with a sliding plate limiting bracket 15, and the lifting connecting sliding plate frame 14 passes through the sliding plate limiting bracket 15 and slides in cooperation with the sliding plate limiting bracket 15.

[0042] In this embodiment, during the lifting and lowering process of the lifting connecting skateboard frame 14, the sliding cooperation between the lifting connecting skateboard frame 14 and the skateboard limiting bracket 15 plays a limiting role in the lifting connecting skateboard frame 14, preventing angular deviation and ensuring the accuracy of the limiting block 5 of the lower corner hinge frame bracket.

[0043] Combination Figure 1 , Figure 4 As shown, the lifting connecting slide frame 14 is provided with a rod abutment 16, which is staggered with the lower corner hinge frame bracket limiting block 5.

[0044] In this embodiment, when limiting the lower corner hinge frame bracket, the insert rod abutment 16 abuts and positions the insert rod structure of the lower corner hinge frame bracket, preventing the insert rod structure of the lower corner hinge frame bracket from tilting upwards during the limiting process, resulting in higher overall limiting accuracy.

[0045] Combination Figure 1 As shown, the insert rod abutment 16 includes an insert rod abutment block 17 disposed on the lifting connecting slide frame 14. The insert rod abutment block 17 and the lower corner hinge frame bracket limiting block 5 are staggered. The insert rod abutment block 17 and the lower corner hinge frame bracket limiting block 5 are respectively connected to the lifting connecting slide frame 14 by fastening bolts.

[0046] In this embodiment, when limiting the lower corner hinge frame bracket, the insertion rod abutment block 17 abuts and positions the insertion rod structure of the lower corner hinge frame bracket, preventing the insertion rod structure of the lower corner hinge frame bracket from tilting upwards during the limiting process. The overall limiting accuracy is higher and more precise. The insertion rod abutment block 17 and the lower corner hinge frame bracket limiting block 5 are respectively connected to the lifting connecting slide frame 14 by fastening bolts, which makes disassembly and assembly simple and convenient, and facilitates maintenance and replacement by staff.

[0047] The working principle of this invention is:

[0048] When gripping the lower corner hinge frame bracket, the lower corner hinge frame bracket is placed below the lower corner hinge frame bracket limiting block 5. At this time, cylinder 133 is activated, and the power shaft of cylinder 133 drives the lifting connecting slide frame 14 and the lower corner hinge frame bracket limiting block 5 to move up and down. The degree of automation is high. The lower corner hinge frame bracket is limited by the bracket locking clamp 7 on the lower corner hinge frame bracket limiting block 5. The locking opening 10 facilitates the locking and fixing of the lower corner hinge frame bracket. The bracket locking clamp 7 and the lower corner hinge frame bracket limiting block 5 are integrally formed, with high strength and long service life. This ensures that the insertion rod seat of the lower corner hinge frame bracket enters the insertion rod seat alignment chamber 8, ensuring that the lower corner hinge frame bracket is completely limited in the center. The limiting accuracy and automation are high, the structure is simple, and the stability is reliable.

[0049] The pivot alignment block 12 is used to align the pivot of the lower corner hinge frame bracket. The anti-interference opening 13 can prevent collisions with other structures of the lower corner hinge frame bracket. The shape is well-matched to prevent collision interference. The pivot alignment block 12 and the lower corner hinge frame bracket limiting block 5 are integrally formed, which has high strength and long service life.

[0050] During the lifting and lowering process of the lifting connecting skateboard frame 14, the sliding cooperation between the lifting connecting skateboard frame 14 and the skateboard limiting bracket 15 plays a limiting role in preventing angular displacement and ensuring the accuracy of the limiting block 5 of the lower corner hinge frame bracket.

[0051] When limiting the lower corner hinge frame bracket, the insertion rod abutment block 17 abuts and positions the insertion rod structure of the lower corner hinge frame bracket, preventing the insertion rod structure of the lower corner hinge frame bracket from tilting upwards during the limiting process. The overall limiting accuracy is higher and more precise. The insertion rod abutment block 17 and the lower corner hinge frame bracket limiting block 5 are respectively connected to the lifting connecting slide frame 14 by fastening bolts, which is simple and convenient to disassemble and assemble, and facilitates maintenance and replacement by staff.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention.

[0053] Although this document frequently uses terms such as gripping and limiting base 1, drive fixing plate 2, lower corner hinge frame bracket limiting and fixing assembly 3, lifting drive component 4, lower corner hinge frame bracket limiting block 5, lower corner hinge frame bracket snap-fit ​​component 6, bracket snap-fit ​​clamping plate 7, insertion rod seat alignment chamber 8, snap-fit ​​interface 9, snap-fit ​​opening 10, rotating shaft alignment component 11, rotating shaft alignment block 12, anti-interference opening 13, cylinder 133, lifting connecting slide frame 14, slide plate limiting bracket 15, insertion rod abutment component 16, and insertion rod abutment block 17, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of the invention; interpreting them as any additional limitation would contradict the spirit of the invention.
