[0029] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0030] The technical solution of the present utility model is further described below with reference to the accompanying drawings.

[0031] Figure 1-6 A device for pressing nuts into pipe fittings for a cart is shown, comprising: a flat loading mechanism 1, two sets of plugging mechanisms 2, a shaping mechanism 3, a first movable module 4, a second movable module 5 and a workbench 6. The workbench 6 is fixed with the flat loading mechanism 1, two sets of plugging mechanisms 2, the shaping mechanism 3 and the second movable module 5 in sequence from one end to the other end. The first movable module 4 is cooperatively arranged on the side guide rail of the workbench 6. The flat loading mechanism 1 moves the pipe fitting horizontally to the position to be grasped. After grasping the pipe fitting, the first movable module 4 moves successively to the positions of the plugging mechanism 2 and the shaping mechanism 3 to press nuts into the pipe fitting and process it into standard parts. The second movable module 5 moves the standard-processed pipe fitting to the next workstation.

[0032] like Figure 2 The flat loading mechanism 1 includes a positioning tool 11 and a loading and transferring cylinder 12. The positioning tool 11 is used to hold pipe fittings. The positioning tool 11 is placed on the telescopic end of the loading and transferring cylinder 12, and the loading and transferring cylinder 12 is installed on the workbench 6.

[0033] like Figure 3, two groups of plugging mechanisms 2 are arranged adjacent to each other on the left and right sides of the workbench 6. Each group of plugging mechanisms 2 includes an automatic feeding mechanism 21, a lifting cylinder 22, a plugging cylinder 23, a cylinder fixing seat 24, a front and rear telescopic cylinder 25, a front and rear sliding plate 27 and a positioning cylinder 29. The plugging mechanism 2 on the right side also includes a left and right telescopic cylinder 26 and a left and right sliding plate 28. The plugging cylinder 23 and the cylinder fixing seat 24 are both installed on the front and rear sliding plates 27 and are adjusted by the front and rear telescopic cylinder 25. The lifting cylinder 22, the front and rear telescopic cylinder 25, the front and rear sliding plates 27 and The positioning cylinders 29 are mounted on the left and right sliding plates 28 and are adjusted forward and backward by the left and right telescopic cylinders 26. When the pipe reaches the plugging position B, the positioning cylinders 29 on both sides press the pipe to keep it fixed. The front and rear telescopic cylinders 25 move the cylinder holder 24 and the plugging cylinder 23 backward to the designated position. The nut emerging from the flow channel of the automatic feeding mechanism 21 is pushed up to the plugging end of the plugging cylinder 23 by the lifting cylinder 22. When the pipe is sucked by the air pressure, the front and rear telescopic cylinders 25 move the cylinder holder 24 and the plugging cylinder 23 forward to the original plugging position B to plug the pipe. If the size of the pipe changes, the left and right or front and rear cylinders can be adjusted through the control system to meet the plugging requirements of pipes of different sizes and shapes.

[0034] The plugging cylinder 23 and cylinder fixing seat 24 in the plugging mechanism 2 can be disassembled and replaced with an oil pressure mechanism for plugging according to actual conditions, or a small punch can be used directly instead to meet the requirements of different plugging processes for different pipe products.

[0035] The shaping mechanism 3 is used to shape the pipe to the standard size after completing the previous plugging process, so as to meet the size requirements of the drawing. Figure 4 The system includes a telescopic cylinder 31, a sliding assembly 32, a fixed cylinder 33, a fixed block 34, and fixed bases 35, a horizontal cylinder 36, and a lifting cylinder 37, all located in the center of the processing station C. The fixed cylinder 33 is fixed to the sliding assembly 32, and the fixed block 34 is mounted on the telescopic end of the fixed cylinder 33. The telescopic cylinder 31 is adjusted forward and backward according to the size of the pipe. The cylinder body of the horizontal cylinder 36 is fixed to the telescopic end of the lifting cylinder 37, and the cylinder body of the lifting cylinder 37 is fixed to the fixed base 35. When the pipe reaches the processing station C, the fixed block 34 presses against the pipe, and the shaping rod on the horizontal cylinder 36 processes the pipe into a standard part.

[0036] like Figure 5The first movable module 4 includes a first clamping cylinder 41, a first clamping jaw 42, a shifting cylinder 43, a lifting cylinder 44 and a first sliding plate 45. When working, the first clamping jaw 42 is controlled by the first clamping jaw cylinder 41 and the shifting cylinder 43 to grab the pipe fitting. The cylinder body of the shifting cylinder 43 is fixed on the telescopic end of the lifting cylinder 44. The cylinder body of the lifting cylinder 44 is fixed on the first sliding plate 45. The first sliding plate 45 is cooperated with the side guide rail of the workbench 6, so that the pipe fitting is moved from the grabbing position A to the plugging position B and the processing position C successively.

[0037] like Figure 6 The second moving module 5 includes a telescopic cylinder 51, a second clamping cylinder 52, a baffle 53, a second clamping jaw 54 and a second sliding plate 55. The end of the telescopic cylinder 51 extends vertically downward, and the second clamping jaw cylinder 52 controls the second clamping jaw 54 to grab the pipe. The second sliding plate 55 is cooperated with the guide rail of the next workstation to move the pipe from the processing position C to the next workstation, realizing automatic loading of the next processing station. The baffle 53 is used to press the pipe to prevent it from shifting.

[0038] The working principle of this utility model:

[0039] When the pipe fitting flows from the front workstation to the flat loading mechanism 1 and is fixed on the position tooling 11, the loading and transferring cylinder 12 starts working to move to the grabbing position A of the first movable module 4, and the pipe fitting is clamped by the first clamping claw 42, and then transferred to the plugging mechanism 2; the positioning cylinder 29 presses the pipe fitting and keeps it fixed. At the same time, the cylinder fixing seat 24 together with the plugging cylinder 23 is moved backward to the specified position by the front and rear telescopic cylinders 25, and the nut coming out of the flow channel on the automatic feeding mechanism 21 is pushed to the plugging end of the plugging cylinder 23 by the lifting cylinder 22. When the pipe fitting is sucked by the air pressure, the entire cylinder fixing seat 24 together with the plugging cylinder 23 is returned to the original plugging position B to plug the pipe fitting; after plugging is completed, it is transferred to the processing position C through the first movable module 4, and the horizontal cylinder 36 shapes the pipe fitting; after shaping is completed, the second movable module 5 starts working to transfer the pipe fitting to the next workstation for subsequent processing.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
