[0025] The utility model provides Figures 1 to 5The double-station nut plugging machine shown includes a machine body 1, on which are provided a clamping mechanism 2, an inserting mechanism 13 and a spot welding mechanism 14. The clamping mechanism 2, the inserting mechanism 13 and the spot welding mechanism 14 are each provided in two groups, which are fixed by the two ends of the metal pipe fittings so that nut inserting, spot welding and other operations can be performed in the double station to realize combined processing.

[0026] The inserting mechanism 13 includes an inserting head, an electric cylinder and other structures, which facilitates the smooth insertion of the nut into the predetermined position of the metal pipe.

[0027] The spot welding mechanism 14 includes a laser welding gun and other structures, which can weld and fix the connection between the nut and the metal pipe.

[0028] In addition, a feeding mechanism 3 is provided at the clamping mechanism 2. The feeding mechanism 3 includes a vibration plate or a feeder and other structures. The nuts are arranged in a certain order and direction, and then automatically transported to a designated position to realize the feeding operation.

[0029] The clamping mechanism 2, the feeding mechanism 3, the inserting mechanism 13, the spot welding mechanism 14 and the plug nut operation are all existing common technologies and will not be described in detail here.

[0030] Considering that the clamping mechanism 2 of the existing nut plugging machine is usually only suitable for metal pipes of a single size and has general applicability, in order to improve the use efficiency, especially for cylindrical metal pipes of different sizes, the clamping mechanism 2 includes a clamping seat 4, and there are two clamping seats 4. The two clamping seats 4 are each provided with a V-shaped groove 5 at one end close to each other. The V-shaped groove 5 can be applicable to metal pipes of various sizes.

[0031] A pressure sensor is installed in the V-shaped groove 5 to monitor the clamping force in real time to ensure stable clamping of the metal pipe.

[0032] In addition, when the metal pipe is fixed between the two V-grooves 5, no matter what its diameter is, its center will naturally fall on the symmetrical center line of the V-groove 5, with an automatic centering function, so that it can be quickly aligned with the insertion mechanism 13 and improve processing accuracy.

[0033] Taking into account the existing method of clamping and fixing the metal pipe by moving two clamping seats 4 towards each other, the operator needs to hold the metal pipe and wait for a certain period of time, and since double-station synchronous processing is required, the metal pipe must be kept in a horizontal state and clamped and fixed at both ends at the same time, which is time-consuming and labor-intensive. In order to realize automatic lifting of the metal pipe and improve processing efficiency, a sliding channel 6 is opened at the bottom end of the clamping seat 4, and there are two sliding channels 6. Both sliding channels 6 are connected to the V-shaped groove 5, and a lifting assembly is provided between the corresponding two sliding channels 6. The lifting assembly includes a support plate 7 and a sleeve 8.

[0034] The support plate 7 includes a fixed section 701 and an insertion section 702, which are integrally formed. The insertion section 702 is plugged into the socket 8, and the fixed section 701 is slidably arranged inside the sliding channel 6. The width of the insertion section 702 is smaller than that of the fixed section 701, ensuring that the fixed section 701 and the socket 8 are stably matched, and the socket 8 has a larger opening at one end close to the support plate 7 (refer to FIG. Figure 5 ), so that the support plate 7 can be inserted into the sleeve 8

[0035] A circular groove 9 is provided at the top of the sliding channel 6, and an elastic telescopic rod 10 is fixedly connected to the inside of the circular groove 9. The support plate 7 is fixedly connected to the bottom end of the corresponding elastic telescopic rod 10, and the socket 8 is fixedly connected to the bottom end of the corresponding elastic telescopic rod 10. A strong spring is provided inside the elastic telescopic rod 10. After the metal pipe is placed, it will not shake at will. Since the opening of the socket 8 at the end close to the support plate 7 is large, even if the support plate 7 drops to a certain extent, it can be stably inserted into the inside of the socket 8.

[0036] There are two groups of lifting components, which are staggered. Figure 2 、 Figure 3 Even if there is a certain distance between the two clamping seats 4 and the insertion section 702 is not inserted into the interior of the socket 8, the two insertion sections 702 are staggered so that the metal pipe will not fall directly when placed between the two clamping seats 4.

[0037] During processing, the operator places the metal pipe on the lifting assembly, and the two ends fall on the two lifting assemblies respectively. The metal pipe is in a horizontal state. At this time, the operator has completed the loading operation and no auxiliary fixation is required afterwards.

[0038] Since the two corresponding insertion sections 702 are staggered, the metal pipe will not fall directly when it is located between the two clamping seats 4.

[0039] Then, the two clamping seats 4 move toward each other, the support plate 7 is inserted into the socket 8 and continues to move. When the metal pipe enters the position between the top of the V-shaped groove 5 and the support plate 7, as the two clamping seats 4 continue to move toward each other, they are squeezed by the metal pipe, and the lifting assembly adaptively slides downward, and the corresponding elastic telescopic rod 10 extends, thereby realizing automatic positioning of the metal pipe.

[0040] The utility model is suitable for metal pipes of various sizes by providing a clamping seat 4, a V-shaped groove 5 and a lifting assembly, and has an automatic centering function to ensure processing accuracy. At the same time, the metal pipe can be lifted so that the metal pipe is in a horizontal state. When positioning, the lifting assembly can adaptively slide downward to realize automatic positioning of the metal pipe, thereby improving the use efficiency of the double-station nut plugging machine.

[0041] The clamping mechanism 2 also includes structures such as an electric push rod, which is installed on the body 1. The two clamping seats 4 are fixedly connected to a docking block 11 at one end away from each other. A docking hole 12 is provided on the docking block 11. In actual use, a bolt is passed through the docking hole 12 to fix the docking block 11 on the telescopic end of the electric push rod, and the clamping seat 4 is driven to move by the electric push rod.
