Description

Technical Field

[0001] This utility model relates to an automatic flipping double-sided rivet processing structure, and in particular to an automatic flipping double-sided rivet processing structure, belonging to the field of rivet technology. Background Technology

[0002] A rivet is a nail-shaped object used to connect two parts with through holes. It typically consists of two parts: a rivet body and a rivet head. The principle of rivet operation is based on the structure of the rivet body. One side of the rivet passes through the workpiece to be connected, and then the rivet head is fitted onto the other side. Then, by applying a certain force, the tail of the rivet body is stretched, causing it to expand and fill the hole in the workpiece, thus tightly connecting and securing the two workpieces.

[0003] When riveting, the equipment sometimes needs to process both sides. During processing, the workpiece is placed on the processing plate for positioning before riveting. However, the existing equipment processes only one side of the workpiece, and then the worker flips the workpiece over for processing. When flipping it to the other side, it needs to be repositioned and fixed. The operation process is cumbersome and troublesome, which greatly reduces the processing efficiency of riveting.

[0004] Therefore, it is urgent to improve the rivet processing structure to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic flipping double-sided riveting processing structure. When double-sided riveting of a workpiece is required, one side is processed first. Then, the clamping frame holding the workpiece is flipped using a drive motor so that the other side faces upward. The riveting machine can then be used to rivet the workpiece, eliminating the need to change the position of the workpiece and fix it in place, thus greatly improving the processing efficiency of riveting.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: an automatic flipping double-sided rivet processing structure, comprising a base, with telescopic mechanisms provided on both sides of the upper surface of the base, the upper ends of the two telescopic mechanisms jointly supporting a flipping clamping frame, and a drive motor for driving the flipping clamping frame being provided on one side of one of the telescopic mechanisms; the flipping clamping frame includes symmetrically arranged support bars and clamping bars slidably connected to both ends of the inner side of the support bars, clamping mechanisms being provided on the inner side of the clamping bars, and a cavity being opened on the upper surface of the base, with a support structure for supporting the flipping clamping frame being provided in the cavity.

[0007] Preferably, the telescopic mechanism includes an electric telescopic rod disposed on both sides of the upper surface of the base and a connecting block disposed on the upper end of the electric telescopic rod, the drive motor being disposed on the outside of one of the connecting blocks, and a positioning mechanism being disposed on the inside of one of the connecting blocks.

[0008] Preferably, each of the two support bars is provided with a connecting rod that is rotatably connected to the connecting block on its outer side, and one of the connecting rods extends through to the outer side of the connecting block and is connected to the output end of the drive motor.

[0009] Preferably, both ends of the inner side of the support bar are provided with electric slide rails for driving the clamping bar to slide, and a synchronizing rod is provided between the two clamping bars.

[0010] Preferably, the clamping mechanism includes a fixing plate disposed on the upper and lower sides of the inner wall of the clamping strip, a miniature electric telescopic rod disposed on the fixing plate, and a clamping plate connected to the lower end of the miniature electric telescopic rod, wherein a rubber anti-slip pad is provided on the lower end surface of the clamping plate.

[0011] Preferably, a sliding groove is provided on one side of the inner wall of one of the connecting blocks, and the positioning mechanism includes a second micro electric telescopic rod disposed inside the sliding groove and a positioning plate connected to the telescopic end of the second micro electric telescopic rod, wherein the upper end face of the positioning plate contacts the lower end face of the support bar.

[0012] Preferably, the support structure includes a second electric telescopic rod disposed inside the cavity and a support block supported by the telescopic end of the second electric telescopic rod, and a rubber pad is disposed on the surface of the support block.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. In use, adjust the multiple clamping bars at both ends according to the length of the workpiece, then push the workpiece between the two fixed plates. Use the extension of the mini electric telescopic rod to clamp and fix both sides of the workpiece. Then use a riveting machine to rivet the current upper surface of the workpiece. After that, use the drive motor to drive the workpiece with the clamping and flipping frame to flip it so that the unprocessed side of the workpiece faces upward. Then use the riveting machine to rivet it. This eliminates the need to change the position of the workpiece and fix it in the middle, which greatly improves the processing efficiency of riveting.

[0015] 2. When the flip clamping frame is flipped, the second micro electric telescopic rod drives the positioning plate to retract into the sliding groove without affecting the flip clamping frame. After the flipping action is performed, the positioning plate is slid out again by extending the second micro electric telescopic rod. When the lower end face of the flip clamping frame flips to the state of contact with the upper end face of the positioning plate, the drive motor will stop, so that the flip clamping frame reaches the horizontal state after flipping.

Detailed Implementation

[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] like Figures 1-5As shown, the automatic flipping double-sided rivet processing structure provided in this embodiment includes a base 1. Telescopic mechanisms 2 are provided on both sides of the upper surface of the base 1. The upper ends of the two telescopic mechanisms 2 jointly support the flipping clamping frame 3. A drive motor 4 for driving the flipping clamping frame 3 is provided on one side of one of the telescopic mechanisms 2. The telescopic mechanism 2 includes an electric telescopic rod 10 provided on both sides of the upper surface of the base 1 and a connecting block 11 provided on the upper end of the electric telescopic rod 10. The telescopic rod 10 can drive the flipping support frame 3 to rise or fall by telescopic extension, so that it can adapt to processing parts of various lengths. The drive motor 4 is provided on the outside of one of the connecting blocks 11, and a positioning mechanism 1101 is provided on the inside of one of the connecting blocks 11.

[0025] Furthermore, a sliding groove 18 is provided on one side of the inner wall of one of the connecting blocks 11. The positioning mechanism 1101 includes a second micro electric telescopic rod 19 disposed inside the sliding groove 18 and a positioning plate 20 connected to the telescopic end of the second micro electric telescopic rod 19. The upper end face of the positioning plate 20 contacts the lower end face of the support bar 5. When the flip clamping frame 3 is flipped, the second micro electric telescopic rod 19 drives the positioning plate 20 to retract into the sliding groove 18 without affecting the flipping of the flip clamping frame 3. After the flipping action is performed, the positioning plate 20 is again driven to slide out by the extension of the second micro electric telescopic rod 19. When the lower end face of the flip clamping frame 3 is flipped to the state of contact with the upper end face of the positioning plate 20, the drive motor 4 will stop, so that the flip clamping frame 3 reaches the horizontal state after flipping.

[0026] The flip-grip frame 3 includes symmetrically arranged support bars 5 and clamping bars 6 slidably connected to both ends of the inner side of the support bars 5. Each of the two support bars 5 has a connecting rod 12 rotatably connected to a connecting block 11 on its outer side. One of the connecting rods 12 extends through the outer side of the connecting block 11 and connects to the output end of the drive motor 4. By using the drive motor 4 to rotate the connecting rod 12, the flip-grip frame 3 can be flipped. Each end of the inner side of the support bar 5 has an electric slide rail 13 for sliding the clamping bars 6. A synchronizing rod 14 is provided between the two clamping bars 6 to ensure that the support bars 5 on both sides rotate synchronously.

[0027] A clamping mechanism 8 is provided on the inner side of the clamping bar 6. The clamping mechanism 8 includes a fixing plate 15 provided on the upper and lower sides of the inner wall of the clamping bar 6, a miniature electric telescopic rod 16 provided on the fixing plate 15, and a clamping plate 17 connected to the lower end of the miniature electric telescopic rod 16. A rubber anti-slip pad is provided on the lower end surface of the clamping plate 17. The rubber anti-slip pad can improve the clamping and fixing effect of the workpiece and will not damage the workpiece.

[0028] The upper surface of the base 1 has a cavity, and a support structure 9 for supporting the flip clamping frame 3 is provided in the cavity. The support structure 9 includes a second electric telescopic rod 21 set inside the cavity and a support block 22 supported by the telescopic end of the second electric telescopic rod 21. When the workpiece needs to be riveted, the second electric telescopic rod 21 rises, driving the support block 22 to rise and contact the lower end surface of the workpiece, thus providing support. A rubber pad is provided on the surface of the support block 22. The rubber pad can prevent the workpiece from being damaged during compression, and the support block 22 can be height adjusted so as not to affect the flipping action of the flip clamping frame 3.

[0029] like Figures 1-5 As shown, the principle of the automatic flipping double-sided rivet processing structure provided in this embodiment is as follows: In use, multiple clamping bars 6 at both ends are slidably adjusted according to the length of the workpiece. Then, the workpiece is pushed between two fixed plates 15. The extension of the micro electric telescopic rod 16 drives the clamping plate 17 to clamp and fix both sides of the workpiece. Then, the riveting machine is used to rivet the current upper surface of the workpiece. After that, the drive motor 4 drives the workpiece with the clamping and flipping clamping frame 3 to flip, so that the unprocessed side of the workpiece is flipped upward. Then, the riveting machine is used to rivet it.
