Description

Technical Field

[0001] This utility model relates to the field of tapping machine technology, and in particular to a defective nut separation device for a tapping machine. Background Technology

[0002] Many existing fully automatic nut tapping machines are unable to screen out defective products during the production process, requiring manual screening later on. This is very troublesome and greatly increases labor costs and efficiency. The common separation method on the market is to adjust or replace the fixtures and taps as much as possible to reduce the defect rate. Although this can ensure a lower defect rate, it requires continuous debugging and monitoring of the equipment during processing, which is very laborious, and the defect rate is still very high.

[0003] In the existing technology, it is not convenient to separate defective products. Therefore, we propose a defective nut separation device for tapping machines to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the inconvenience of separating defective products, and to propose a defective nut separation device for a tapping machine.

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

[0006] A defective nut separation device for a tapping machine includes:

[0007] Separate shell;

[0008] The discharge hole, located at the bottom of the separation shell, is used to discharge defective products.

[0009] The first mounting block is fixedly mounted on the separation shell;

[0010] The rotating shaft is rotatably mounted on the first mounting block.

[0011] A connecting shaft, one end of which is fixedly connected to one end of a rotating shaft;

[0012] The inner plate, which is fixedly connected to the connecting shaft, is used to seal the material discharge hole;

[0013] The flipping mechanism, connected to the rotating shaft, is used to rotate the rotating shaft, thereby flipping the inner plate.

[0014] Preferably, the flipping mechanism includes a cylinder, and a U-shaped push block is mounted on the output shaft of the cylinder.

[0015] Preferably, a rotating shaft is rotatably mounted on the inner side of the U-shaped push block, and a connecting piece is fixedly mounted on the rotating shaft, with the connecting piece being fixedly connected to the rotating shaft.

[0016] Preferably, the inner side of the U-shaped push block has two rotating holes, and the outer side of the rotating shaft contacts the inner wall of the rotating holes.

[0017] Preferably, a second mounting block is fixedly mounted on the separation shell, and a connecting rod is rotatably mounted on the second mounting block, with one end of the connecting rod fixedly connected to the other end of the connecting shaft.

[0018] Preferably, a top cover is installed on the top of the separation shell.

[0019] Preferably, a side cover is installed on the side of the separation shell.

[0020] Preferably, a U-shaped frame is installed on one side of the separation shell, and multiple small holes are opened at the bottom of the U-shaped frame. A connecting bracket is fixedly installed on the outside of the U-shaped frame.

[0021] Compared with the prior art, the advantages of this utility model are:

[0022] When defective products enter the separation shell, the cylinder pushes the U-shaped push block to move, which in turn drives the connecting plate to move. The connecting plate then drives the rotating shaft to rotate, which in turn drives the connecting shaft to rotate. The connecting shaft then causes the inner plate to flip, opening the discharge hole. This allows the defective products to fall through the discharge hole, slide out of the inner plate, and be discharged directly from the separation shell. Then, the cylinder drives the U-shaped push block to return to its original position, resetting the inner plate and sealing the discharge hole. Finally, qualified products slide from the top of the inner plate to the U-shaped frame, thus separating the defective nuts.

[0023] This invention uses an inner plate in a cylinder rod flipping device to allow defective products to fall to the bottom of the device, and then restores the original state so that good products can slide smoothly through the inner plate into the good product area, thus achieving separation of defective products and saving labor.

[0029] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, and not all embodiments.

[0030] Example 1

[0031] Reference Figures 1-4 A defective nut separation device for a tapping machine, comprising:

[0032] Separate shell 1;

[0033] The discharge hole 2 is located at the bottom of the separation shell 1 and is used to discharge unqualified products.

[0034] The first mounting block 3 is fixedly mounted on the separation shell 1;

[0035] Rotary shaft 4 is rotatably mounted on the first mounting block 3;

[0036] One end of the connecting shaft 5 is fixedly connected to one end of the rotating shaft 4;

[0037] The inner plate 6 is fixedly connected to the connecting shaft 5 and is used to seal the material discharge hole 2;

[0038] The flipping mechanism is connected to the rotating shaft 4 and is used to rotate the rotating shaft 4, thereby flipping the inner plate 6.

[0039] In this embodiment, the flipping mechanism includes a cylinder 8, and a U-shaped push block 9 is mounted on the output shaft of the cylinder 8.

[0040] In this embodiment, a rotating shaft 10 is rotatably mounted on the inner side of the U-shaped push block 9, and a connecting piece 7 is fixedly mounted on the rotating shaft 10. The connecting piece 7 is fixedly connected to the rotating shaft 4.

[0041] In this embodiment, two rotating holes are provided on the inner side of the U-shaped push block 9, and the outer side of the rotating shaft 10 is in contact with the inner wall of the rotating hole.

[0042] In this embodiment, a second mounting block 15 is fixedly installed on the separation shell 1, and a connecting rod 16 is rotatably installed on the second mounting block 15. One end of the connecting rod 16 is fixedly connected to the other end of the connecting shaft 6.

[0043] In this embodiment, a top cover 11 is installed on the top of the separation shell 1.

[0044] In this embodiment, a side cover 12 is installed on the side of the separation shell 1.

[0045] In this embodiment, a U-shaped frame 13 is installed on one side of the separation shell 1, and multiple small holes are opened at the bottom of the U-shaped frame 13. A connecting bracket 14 is fixedly installed on the outside of the U-shaped frame 13.

[0046] This solution employs a defective product separation method. Before the finished workpiece falls into the finished product area, a device is installed to screen for defective products. This device is connected to the tapping machine system. Its feature is that the tapping torque parameter range is set through the machine tool system to determine the tapping accuracy and finished product quality of each set of nuts. Any product exceeding or falling below the set range is considered a defective product. The data is transmitted back to the system via a sensor, and then transmitted to the separation device. The separation device flips the inner plate of the device using a cylinder rod, allowing the defective products to fall below the device. Then, the device is restored to its original state, allowing the good products to slide smoothly through the inner plate into the good product area. This process is repeated.

[0047] In this embodiment, when a defective product enters the separation shell 1, the cylinder 8 pushes the U-shaped push block 9 to move. The U-shaped push block 9 drives the connecting piece 7 to move, the connecting piece 7 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the connecting shaft 5 to rotate, and the connecting shaft 5 drives the inner plate 6 to flip, so that the discharge hole 2 opens, allowing the defective product to fall from the discharge hole 2, slide out from the inner plate 6, and be discharged directly from the separation shell 1. Then, the cylinder 8 drives the U-shaped push block 9 to return to its original position, so that the inner plate 6 is reset and the discharge hole 2 is blocked. Then, the qualified product slides from the top of the inner plate 6 to the U-shaped frame 13, realizing the separation of the defective nut.

[0048] Example 2

[0049] The difference from Embodiment 1 is that the top of the inner panel 6 is provided with two protective plates, which prevent defective products from falling from the side when they slip off.

[0050] The rest is the same as in Example 1.

[0051] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
