DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1:

[0026] Combine Figure 2 、 Figure 3 ,as well as Figure 4 As shown together, a positioning tool 3 includes a base plate 31, a positioning block 32 is provided on the base plate 31, and a positioning groove 321 is provided on the upper surface of the positioning block 32. The positioning groove 321 is used to place and position the screen plate 4 and the connecting piece 5 that need to be riveted together.

[0027] Combine Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 ,as well as Figure 7 As shown together, the sieve plate 4 has a sieve plate positioning surface 41, the connecting member 5 has a connecting member positioning surface 51, the positioning groove 321 is a through groove, one side wall of the positioning groove 321 is defined as a first positioning surface 3211, and the other side wall of the positioning groove is defined as a second positioning surface 3212. When the sieve plate 4 and the connecting member 5 are placed and positioned, the sieve plate positioning surface 41 abuts against the first positioning surface 3211, and the connecting member positioning surface 51 abuts against the second positioning surface 3212.

[0028] Preferably, four limiting blocks 33 are further provided on the bottom plate 31 . The four limiting blocks 33 together enclose a square area, and the positioning block 32 is provided in the square area.

[0029] Further preferably, since the screen plate 4 is relatively long, a support block 34 is further provided on the bottom plate 31 , and the support block 34 is used to support the screen plate 4 .

[0030] Combine Figure 6 as well as Figure 7 As shown together, the screen plate 4 has a first rivet hole 42 and a second rivet hole 43, and the connecting piece 5 has a rivet hole A 52 and a rivet hole B 53. When the screen plate 4 and the connecting piece 5 are placed and positioned, the first rivet hole 42 is aligned with the rivet hole A 52, and the second rivet hole 43 is aligned with the rivet hole B 53.

[0031] Combine Figure 5 As shown, preferably, a magnet placement hole 3213 is further provided at the bottom of the positioning groove 321. When the screen 4 and the connecting piece 5 are placed and positioned, a magnet is placed in the magnet placement hole 3213. Since the screen 4 and the connecting piece 5 are made of metal materials, such as iron or other metal materials, the screen 4 and the connecting piece 5 can be better adsorbed on the positioning block 32 under the action of the magnet.

[0032] Example 2:

[0033] Combine Figure 1 as well as Figure 2 As shown together, this embodiment discloses a riveting device, which includes the positioning tool 3 of the first embodiment. The riveting device includes a riveting machine 2, and the riveting machine 2 includes a riveting head 21. The positioning tool 3 is located below the riveting head 21.

[0034] Preferably, the riveting device further comprises a support frame 1, and the positioning tool 3 is arranged on the support frame 1. The bottom plate 31 of the positioning tool 3 is preferably detachably fixed on the support frame 1.

[0035] Further preferably, the support frame 1 is fixedly connected to the frame 22 of the riveting machine 2 .

[0036] The press riveting machine 2 is a purchased part. The structure, working principle, and working process of the press riveting machine 2 are common knowledge to those skilled in the art and will not be described in detail here.

[0037] The following describes in detail the process of riveting the screen plate 4 and the connecting piece 5 together using the riveting equipment of the present invention:

[0038] Combine Figure 1 as well as Figure 2As shown together, the bottom plate 31 of the positioning fixture 3 is placed on the support frame 1, and the bottom plate 31 is fixed to the support frame 1. The connecting member 5 is placed in the positioning groove 321 of the positioning block 32, and the positioning surface 51 of the connecting member is pressed against the second positioning surface 3212. Under the adsorption effect of the magnet, the connecting member 5 is positioned on the positioning block 32. Then, the screen piece 4 is placed in the positioning groove 321 of the positioning block 32, and when placing it, it is ensured that the first rivet hole 42 is aligned with the rivet hole A 52, and the second rivet hole 43 is aligned with the rivet hole B 53. At the same time, the positioning surface 41 of the screen piece is pressed against the first positioning surface 3211. Similarly, under the adsorption effect of the magnet, the screen piece 4 is positioned on the positioning block 32.

[0039] Take two rivets, defined as a first rivet 6 and a second rivet 7, and pass the first rivet 6 through the first rivet hole 42 and the rivet hole A 52, and pass the second rivet 7 through the second rivet hole 43 and the rivet hole B 53.

[0040] Then, the riveting machine 2 is started and begins to work, and the riveting head 21 of the riveting machine 2 moves downward, acting on the first rivet 6 and the second rivet 7 at the same time, completing the riveting of the screen plate 4 and the connecting member 5.

[0041] Such a riveting process can effectively avoid the problem in the prior art of first riveting the first rivet 6 and then riveting the second rivet 7, which causes the second rivet hole 43 and the rivet hole B 53 to be misaligned when the second rivet 7 is riveted, making it difficult for the second rivet 7 to pass through the second rivet hole 43 and the rivet hole B 53 at the same time, requiring multiple repair processes to complete the riveting, and the second rivet 7 becomes skewed after riveting, thereby effectively avoiding the possibility that the screen plate 4 and the connecting piece 5 cannot be used normally or are directly scrapped after riveting, thereby increasing the product yield, reducing the company's production costs, and improving the company's economic benefits.
