Technical Field

[0001] This invention relates to the field of automatic assembly technology, and in particular to a quick tightening mechanism. Background Technology

[0002] Threaded connections are a common type of connection in product assembly.

[0003] In traditional product assembly, the loosening or tightening of screws is entirely done manually. On the one hand, the labor intensity of workers is high and the influence of human factors is relatively large, often making it difficult to meet the technical requirements for tightening torque. On the other hand, manual operation seriously affects the assembly efficiency of the product.

[0004] The existing tightening mechanism has poor stability when clamping products, resulting in reduced tightening efficiency. Summary of the Invention

[0005] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide a fast tightening mechanism that can quickly and efficiently rotate, tighten, and unlock products, and can be adapted to a variety of products.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a quick tightening mechanism, characterized in that it includes a locking component, a tightening component, and a tightening drive component, wherein the tightening drive component is connected to the tightening component and can drive the tightening component to rotate, the locking component is rotatably mounted on the tightening component and connected to the locking drive component, and the locking drive component can drive the locking component to rotate, thereby clamping or releasing the product.

[0007] Furthermore, the tightening assembly includes a tightening gear, and the tightening drive assembly includes a tightening drive motor and a tightening drive gear. The output shaft of the tightening drive motor is connected to the tightening drive gear, and the tightening drive gear meshes with the tightening gear to form a meshing transmission.

[0008] Furthermore, the tightening gear has a tightening groove for placing the product.

[0009] Furthermore, the locking assembly includes a main rod, an upper rod, and a lower rod, all of which are rotatably mounted on a tightening gear. The upper and lower rods are arranged opposite each other, with one end connected to the main rod and the other end having a locking structure. There is a certain gap between the two locking structures for placing the product's tightening structure. The locking drive assembly includes a cylinder and a drive rod, with the piston rod of the cylinder connected to the drive rod and the free end of the drive rod connected to the main rod.

[0010] Furthermore, the tightening gear is also provided with a first tension spring rod, a second tension spring rod, a third tension spring rod, and a fourth tension spring rod. The first and second tension spring rods both pass through the main rod and are connected by a first tension spring. The main rod is also provided with an oblong hole, in which either the first or second tension spring rod is located. A fifth tension spring rod is provided on the upper rod, and the third and fifth tension spring rods are connected by a second tension spring. A sixth tension spring rod is provided on the lower rod, and the sixth tension spring rod is connected to the fourth tension spring rod by a third tension spring.

[0011] Furthermore, the tightening gear is rotatably mounted on the main frame, and the main frame is provided with multiple roller supports, each with a roller that contacts the tightening gear.

[0012] Furthermore, a dustproof plate is provided on the main frame, and a dustproof area is formed between the dustproof plate and the main frame, with the tightening drive gear located within the dustproof area.

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0024] Example 1

[0025] See appendix Figure 1 As shown, a quick tightening mechanism includes a main frame 9, on which a tightening component 2 is rotatably mounted. The tightening component 2 is provided with a locking component 1, which is used to lock the product structure to be tightened placed on the tightening component 2, thereby preventing the product from shifting or falling off. The main frame 9 is also equipped with a tightening drive component 3, which is connected to the tightening component 2. The tightening drive component 3 can drive the tightening component 2 to rotate the product structure to be tightened, thereby achieving a threaded connection.

[0026] See appendix Figure 3 , 4 As shown, the tightening assembly 2 includes a tightening gear 21 and a tension spring on it. The tightening gear 21 is rotatably mounted on the main frame 9, and a tightening groove 211 for placing the product is provided on the tightening gear 21. The locking assembly 1 includes a main rod 101, an upper rod 102, and a lower rod 103. The main rod 101 and the upper rod 102 are both rotatably mounted on the tightening gear 21, and the lower rod 103 is fixedly mounted on the tightening gear 21. The upper rod 102 and the lower rod 103 are arranged opposite to each other, and one end of the upper rod 102 is connected to the main rod 101. The connection is provided with a locking structure 104 on the other end and a locking structure 104 on the end of the lower rod 103. There is a certain distance between the two locking structures 104 for the product to be tightened structure to be placed. In this embodiment, the locking structure 104 is trapezoidal, but it can also be set to other shapes that can match the product to be tightened structure. When the product is placed in the tightening groove 211, the product to be tightened structure is located between the two locking structures 104 and contacts the locking structure 104 to achieve limiting and clamping.

[0027] See appendix Figure 2 As shown, the main frame 9 is also equipped with a locking drive assembly, which includes a cylinder 4 and a drive rod. The cylinder 4 is mounted on the main frame 9 and the piston rod is connected to the drive rod. The free end of the drive rod is connected to the main rod 101. When the drive rod drives the main rod 101 to rotate through the cylinder 4, the upper rod 102 will rotate, causing the locking structure 104 mounted on it to move closer to the lower rod 103. The distance between the two locking structures 104 is reduced. At this time, both locking structures 104 are in close contact with the structure to be tightened of the product, improving the clamping stability during the tightening process.

[0028] See appendix Figure 3 , 4As shown, the tension spring part includes a tension spring rod and a tension spring. The tightening gear 21 is provided with a first tension spring rod, a second tension spring rod and a third tension spring rod. The first tension spring rod and the second tension spring rod both pass through the main rod 101 and are connected by the first tension spring 5. The main rod 101 is also provided with a waist-shaped hole 6. The first tension spring rod or the second tension spring rod is located in the waist-shaped hole 6. When the main rod 101 rotates, the rotation position can be limited by the waist-shaped hole 6 and the tension spring rod. The upper rod 102 is provided with a fifth tension spring rod. The third tension spring rod and the fifth tension spring rod are connected by the second tension spring 7, which can limit and reset the rotation of the upper rod 102 and the main rod 101.

[0029] A limiting plate is also provided on the tightening gear 21. The main rod 101, the upper rod 102 and the lower rod 103 are all located between the limiting plate and the tightening gear 21. The first tension spring 5 and the second tension spring 7 are both located on the side of the limiting plate away from the tightening gear 21. A limiting groove for placing product parts is provided on the limiting plate.

[0030] See appendix Figure 2 As shown, the tightening drive assembly 3 includes a tightening drive motor 31 and a tightening drive gear 32. The tightening drive assembly 3 is mounted on the main frame 9, and the output shaft of the tightening drive motor 31 is connected to the tightening drive gear 32. The tightening drive gear 32 meshes with the tightening gear 21 to form a meshing transmission. Alternatively, two tightening drive gears 32 can be configured, with both tightening drive gears 32 meshing with the tightening gear 21 and having tightening drive rods mounted on them. Each tightening drive rod has a drive wheel mounted on it, and the two drive wheels are connected by a drive belt. Using two tightening drive gears 32 provides greater stability than using only one tightening drive gear 32.

[0031] See appendix Figure 2 As shown, the main frame 9 is provided with multiple roller brackets 10, and rollers 11 are provided on the roller brackets 10. The rollers 11 are in contact with the tightening gear 21, which can reduce the friction of the tightening gear 21 rotation, and at the same time realize the functions of limiting and guiding.

[0032] See appendix Figure 1 As shown, a dustproof plate 12 is provided on the main frame 9, and a dustproof area is formed between the dustproof plate 12 and the main frame 9. The tightened drive gear 32 is located in the dustproof area, which can prevent the accumulation of impurities or dust on the toothed part through the dustproof plate 12, making it difficult for it to mesh and rotate.

[0033] This application applies to rod-shaped products, which can connect two products by threading a nut. The structure to be tightened is the nut, and the locking structure 104 is a stepped structure that can cooperate with the outer wall structure of the nut. After the locking structure 104 contacts and limits the nut, the tightening gear 21 can drive the nut to rotate and complete the tightening.

[0034] The bottom of the main frame 9 can also be equipped with a lifting mechanism and a horizontal moving mechanism, so that the tightening mechanism can be displaced to better match the product position. The lifting mechanism can be electric lifting or ball screw drive. After the product is in place, it drives the main frame 9 to rise, so that the product is located in the tightening groove 211. The structure to be tightened is located between the two clamping structures 104. The cylinder 4 drives the main rod 101 to drive the upper rod 102 to rotate, clamping the structure to be tightened. The tightening drive motor 31 drives the tightening gear 21 to rotate, driving the structure to be tightened to rotate and complete the tightening. At this time, the cylinder 4 drives the main rod 101 to drive the upper rod 102 to rotate, so that the upper rod 102 moves away from the structure to be tightened. The lifting mechanism drives the main frame 9 to fall, so that the main frame 9 moves away from the product.

[0035] Example 2

[0036] See appendix Figure 1 As shown, a quick tightening mechanism includes a main frame 9, on which a tightening component 2 is rotatably mounted. The tightening component 2 is provided with a locking component 1, which is used to lock the product structure to be tightened placed on the tightening component 2, thereby preventing the product from shifting or falling off. The main frame 9 is also equipped with a tightening drive component 3, which is connected to the tightening component 2. The tightening drive component 3 can drive the tightening component 2 to rotate the product structure to be tightened, thereby achieving a threaded connection.

[0037] See appendix Figure 3 , 4 As shown, the tightening assembly 2 includes a tightening gear 21 and a tension spring on it. The tightening gear 21 is rotatably mounted on the main frame 9, and a tightening groove 211 for placing the product is provided on the tightening gear 21. The locking assembly 1 includes a main rod 101, an upper rod 102, and a lower rod 103. The main rod 101, the upper rod 102, and the lower rod 103 are all rotatably mounted on the tightening gear 21. The upper rod 102 and the lower rod 103 are arranged opposite to each other and one end is connected to the main rod 101. The other end is provided with a locking structure 104. There is a certain distance between the two locking structures 104 for placing the product's structure to be tightened. In this embodiment, the locking structure 104 is trapezoidal, but it can also be set to other shapes that can match the structure to be tightened. When the product is placed in the tightening groove 211, the product's structure to be tightened is located between the two locking structures 104 and contacts the locking structure 104, thereby limiting and clamping it.

[0038] See appendix Figure 2As shown, the main frame 9 is also equipped with a locking drive assembly, which includes a cylinder 4 and a drive rod. The cylinder 4 is mounted on the main frame 9 and the piston rod is connected to the drive rod. The free end of the drive rod is connected to the main rod 101. When the drive rod drives the main rod 101 to rotate through the cylinder 4, the upper rod 102 and the lower rod 103 will both rotate, causing the locking structure 104 to move closer to the structure to be tightened. At this time, both locking structures 104 are in close contact with the structure to be tightened of the product, improving the clamping stability during the tightening process.

[0039] See appendix Figure 3 , 4 As shown, the tension spring part includes a tension spring rod and a tension spring. The tightening gear 21 is provided with a first tension spring rod, a second tension spring rod, a third tension spring rod and a fourth tension spring rod. The first tension spring rod and the second tension spring rod both pass through the main rod 101 and are connected by the first tension spring 5. The main rod 101 is also provided with a waist-shaped hole 6. The first tension spring rod or the second tension spring rod is located in the waist-shaped hole 6. When the main rod 101 rotates, it can limit the rotation position through the waist-shaped hole 6 and the tension spring rod. The upper rod 102 is provided with a fifth tension spring rod. The third tension spring rod and the fifth tension spring rod are connected by a second tension spring 7. The lower rod 103 is provided with a sixth tension spring rod. The sixth tension spring rod and the fourth tension spring rod are connected by a third tension spring 8. It can limit and reset the rotation of the upper rod 102, the lower rod 103 and the main rod 101.

[0040] In this embodiment, both the upper rod 102 and the lower rod 103 are rotated. Compared with the method where only the upper rod 102 rotates and moves closer to the lower rod 103, this reduces the squeezing and damage to the product and allows for faster clamping.

[0041] A limiting plate is also provided on the tightening gear 21. The main rod 101, the upper rod 102 and the lower rod 103 are all located between the limiting plate and the tightening gear 21. The first tension spring 5 and the second tension spring 7 are both located on the side of the limiting plate away from the tightening gear 21. A limiting groove for placing product parts is provided on the limiting plate.

[0042] See appendix Figure 2 As shown, the tightening drive assembly 3 includes a tightening drive motor 31 and a tightening drive gear 32. The tightening drive assembly 3 is mounted on the main frame 9, and the output shaft of the tightening drive motor 31 is connected to the tightening drive gear 32. The tightening drive gear 32 meshes with the tightening gear 21 to form a meshing transmission. Alternatively, two tightening drive gears 32 can be configured, with both tightening drive gears 32 meshing with the tightening gear 21 and having tightening drive rods mounted on them. Each tightening drive rod has a drive wheel mounted on it, and the two drive wheels are connected by a drive belt. Using two tightening drive gears 32 provides greater stability than using only one tightening drive gear 32.

[0043] See appendix Figure 2As shown, the main frame 9 is provided with multiple roller brackets 10, and rollers 11 are provided on the roller brackets 10. The rollers 11 are in contact with the tightening gear 21, which can reduce the friction of the tightening gear 21 rotation, and at the same time realize the functions of limiting and guiding.

[0044] See appendix Figure 1 As shown, a dustproof plate 12 is provided on the main frame 9, and a dustproof area is formed between the dustproof plate 12 and the main frame 9. The tightened drive gear 32 is located in the dustproof area, which can prevent the accumulation of impurities or dust on the toothed part through the dustproof plate 12, making it difficult for it to mesh and rotate.

[0045] This application applies to rod-shaped products, which can connect two products by threading a nut. The structure to be tightened is the nut, and the locking structure 104 is a stepped structure that can cooperate with the outer wall structure of the nut. After the locking structure 104 contacts and limits the nut, the tightening gear 21 can drive the nut to rotate and complete the tightening.

[0046] The bottom of the main frame 9 can also be equipped with a lifting mechanism and a horizontal moving mechanism, so that the tightening mechanism can be displaced to better match the product position. The lifting mechanism can be electric lifting or ball screw transmission. After the product is in place, it drives the main frame 9 to rise, so that the product is located in the tightening groove 211. The structure to be tightened is located between the two clamping structures 104. The cylinder 4 drives the main rod 101 to drive the upper rod 102 and the lower rod 103 to rotate, clamping the structure to be tightened. The tightening drive motor 31 drives the tightening gear 21 to rotate, driving the structure to be tightened to rotate and complete the tightening. At this time, the cylinder 4 drives the main rod 101 to drive the upper rod 102 and the lower rod 103 to rotate, so that the upper rod 102 and the lower rod 103 are away from the structure to be tightened. The lifting mechanism drives the main frame 9 to fall, so that the main frame 9 is away from the product.
