[0019] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-5 As shown, the utility model is a riveting device for a special wire tube.

[0021] The riveting device for the special wire tube described in this embodiment includes a frame 11, and a slide plate 13 is provided on the frame 11. The slide plate 13 is respectively provided with a first mounting seat 2, a second mounting seat 10 and a clamping mechanism 14. The first mounting seat 2 and the clamping mechanism 14 are located at both ends for clamping, and the second mounting seat 10 is located between the two. The workpiece 1 is located thereon. These three parts position and fix the workpiece 1. The structure of the first mounting seat 2 and the second mounting seat 10 matches the workpiece 1. The left riveting top 3 and the right riveting top 4 are respectively provided on both sides of the workpiece 1 in the vertical direction to rivet the workpiece 1; the right side of the right riveting top 4 is provided with a power assembly 8 to push it to move; the first guide rail 6 and the second guide rail 7 for movement are provided below the right riveting top 4. The first guide rail 6 is located below the slide plate 13 to adjust the position of the slide plate 13, and the second guide rail 7 is located above the first guide rail 6. The second guide rail 7 is used to adjust the left and right positions of the right riveting top 4. In this embodiment, a third guide rail 15 is also provided between the first guide rail 6 and the slide plate 13, which makes it more convenient to adjust the positions between the parts.

[0022] Furthermore, the clamping mechanism 14 includes a push block 1401, a push rod 1402 and a seat body 1403, and the push rod 1402 is also provided with a handle 12. The push rod 1402 is sleeved with the push block 1401, and sleeved and fixed on the seat body 1403, and the push block 1401 presses the workpiece 1, and the push rod 1402 is provided with a handle 12 for pushing and clamping on the outer side of the seat body 1403.

[0023] Furthermore, the power assembly includes a first gear 82 and a second gear 83, which are fixed on the gear seat 81. The first gear 82 has more teeth than the second gear 83, which saves effort. The gear shaft on the first gear 82 passes through the gear seat 81, and the other end is fixed on the right riveting press top 4. The shaft body 16 on the right riveting press top 4 is sleeved with a compression spring for buffering, and the other protruding end of the shaft body 16 is fixed below the second mounting seat 10 to guide the movement of the right riveting press top 4.

[0024] Furthermore, a hand wheel 9 is provided on the second gear 83, and the right riveting tip 4 is pushed forward and backward by rotating the hand wheel.

[0025] Furthermore, the riveting device for the special wire tube also includes a limit block 5, and the limit block 5 is used to position the riveting depth.

[0026] Furthermore, the slide plate 13 is provided with an adjustable inverted "T"-shaped groove, which can be used to adjust the position.

[0027] Furthermore, a cover 84 is provided above the first gear 82 and the second gear 83 .

[0028] When the riveting device of this special wire tube is used,

[0029] The device presses the workpiece 1 and the special-shaped pipe parts into one end of the first mounting seat 2, and then rivets four convex points around the workpiece 1 and the special-shaped pipe parts, which are stuck in the annular groove at one end of the first mounting seat 2. The workpiece 1 and the special-shaped pipe parts are not easy to fall out, and the fall-out force can be guaranteed to be above 1000N.

[0030] Pressing steps:

[0031] First, place the assembled workpiece 1 and the special-shaped pipe parts into the first mounting seat 2, and then place the other end into the second mounting seat 10 after positioning as required;

[0032] Clamp with push block 1401;

[0033] The hand wheel 9 is shaken to make the right riveting tip 4 move to the left through the second guide rail 7. After the left and right riveting tips contact the workpiece, the hand wheel is continued to be shaken to produce riveting. The workpiece is deformed by riveting to produce two convex points. The depth of riveting is determined by the limit block 5. The position of the limit block is adjusted as required to ensure that the convex point is pressed into the annular groove at one end of the first mounting seat 2. According to this method, the workpiece is reversed and the other two convex points are riveted to complete the riveting.

[0034] The above are preferred implementations of the present invention, which do not limit the protection scope of the present invention. Any modifications and improvements made by those skilled in the art based on the design ideas of the present invention should be regarded as within the protection scope of the present invention.
