[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model aims to solve the problem that the degree of automation is relatively low and manual participation is usually required, which not only increases labor costs but also reduces production efficiency. At the same time, the clamping structure of the chain ring weaving is prone to wear after long-term use, which reduces the stability and efficiency of the clamping and causes the precision and quality of the chain ring weaving to decrease. Figure 1-Figure 3 The chain link weaving machine shown in the figure has an automatic turning unit inside, and includes a workbench 1, a through hole 11 is opened in the middle of the top surface of the workbench 1, and sliding columns 12 are fixedly connected on both sides of the through hole 11, and a rotating column 2 is rotatably arranged inside the through hole 11, and sliding grooves 21 are opened on both sides of the outer periphery of the rotating column 2, and the sliding grooves 21 are slidably connected to the through hole 11; when the chain link weaving machine is weaving chain links, when the chain material and the chain link are installed, one of them needs to be rotated ninety degrees before it can be installed.

[0027] When the rotating column 2 moves up and down, the sliding column 12 in the through hole 11 cooperates with the sliding groove 21, so that the rotating column 2 rotates along the shape of the sliding groove 21. The rotating column 2 rotates while moving up and down, and the chain links can be flipped when chaining.

[0028] The cam 32 is provided with a plurality of cams 34 on the top of the cam 32, and the cam 32 is provided with a plurality of cams 35 on the bottom of the cam 32. The cam 32 is provided with a plurality of cams 35 on the top of the cam 32. The cam 32 is provided with a plurality of cams 35 on the bottom of the cam 32.

[0029] Lubricating oil can significantly reduce the friction coefficient between the chain link and the clamp block 3, thereby reducing the heat and wear generated by friction, which is beneficial to extending the service life of the chain link and the clamp block 3. At the same time, it can reduce the vibration and shaking of the chain link during the clamping process, improve the clamping stability and clamping efficiency of the clamp block 3, and thus ensure the accuracy and quality of chain link weaving.

[0030] It should be noted that the chain link weaving machine includes a feeding mechanism for conveying chain materials and a cutting and bending mechanism. The above is a mature technology in the prior art, which is not shown in the figure and will not be repeated here. The feeding mechanism conveys the chain material to the top of the clamping block 3, and the cutting and bending mechanism cuts and bends the chain material. The bending block cooperates with the forming groove 32 to bend the chain into shape, and the clamping block 3 is in a closed state during bending.

[0031] It should also be noted that a rotating ring can be installed at the bottom of the rotating column 2, and the ring can be connected to the cutting and bending mechanism. The above is the existing technology, not shown in the figure, and will not be repeated here. When the cutting and bending machine is cutting, the rotating column 2 moves up and down, and the chain link flips to complete the flipping, and the chain material is connected to the formed chain link, thereby realizing the automatic flipping and weaving operation, without the need for human participation in the operation, reducing labor costs and improving work efficiency.

[0032] In the present invention, the second cylindrical rod 41 is fixedly connected to both sides of the rotating block 22, and tension springs 42 are provided on both sides of the rotating block 22. The two seven-shaped blocks 23 are fixedly connected to the first cylindrical rod 4 on one side away from each other, and the first cylindrical rod 4 and the second cylindrical rod 41 on one side are fixedly connected to the corresponding tension springs 42; under normal circumstances, the second cylindrical rod 41 pulls the first cylindrical rod 4 downward through the tension spring 42, and the tops of the seven-shaped blocks 23 on both sides are away from each other and form an open shape. When the chain material enters the forming groove 32, the bending block, the chain link and the clamping block 3 are in contact, and the seven-shaped blocks 23 are close to each other.

[0033] It should be noted that a cylindrical hole 5 is provided through the middle of the rotating column 2 and the rotating block 22; after the chain link is formed, it falls downward through the cylindrical hole 5, and a box for collecting the chain link can be placed under the workbench 1. The box is a prior art and is not shown in the figure, so it will not be described here.

[0034] In the present invention, the slide groove 21 is in a spiral shape; the top and bottom ends of the slide groove 21 are ninety degrees apart, and when the rotating column 2 moves up and down, the rotating column 2 can be rotated ninety degrees, thereby completing the flipping of the chain link.

[0035] In the present invention, a forming groove 32 is opened in the middle of one side of the two oil chambers 31 close to each other, and an oil outlet hole 33 connects the forming groove 32 and the oil chamber 31; the forming groove 32 is a groove body formed by the chain link, and the lubricating oil enters the forming groove 32 through the oil outlet hole 33 to lubricate the chain link and the forming groove 32.

[0036] It should be noted that a circular hole 35 is opened through the middle of the forming groove 32, and the circular hole 35 connects the forming groove 32 and the oil chamber 31. An elastic sheet 36 is fixedly connected to the inside of the circular hole 35. The elastic sheet 36 is elastic and is normally located inside the forming groove 32. When the chain link material is bent and formed, the bending block cooperates with the forming groove 32 so that the chain link is located in the forming groove 32 and contacts the elastic sheet 36. The elastic sheet 36 is pressurized inwardly, the pressure inside the oil chamber 31 increases, and the lubricating oil flows out from the oil outlet 33 to lubricate the chain link and the forming groove 32.

[0037] It should also be noted that there is a filling hole at the top of the oil chamber 31 for adding lubricating oil, and a sealing plug is installed in the filling hole. The above are all existing technologies and will not be repeated here.
