[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1 to 3 As shown, a hot air cold riveting device includes a machine base 10 and a housing 1a covered on the machine base 10. It also includes a rotary worktable 20, a positioning fixture 30, and a riveting mechanism 40. The rotary worktable 20 is disposed on the machine base 10, and the positioning fixture 30 is disposed on the rotary worktable 20 for positioning multiple workpieces 100. The riveting mechanism 40 includes a bracket 401, a translation component 41, a hot air component 42, and a riveting component 43. The bracket 401 is disposed on the machine base 10, and the translation component 41 is disposed on the bracket 401. The translation component 41 includes a translation cylinder 411 and a mounting plate 412. The translation cylinder 411 is disposed on the bracket 401, and the mounting plate 412 is slidably disposed on the bracket 401 and connected to the output end of the cylinder 411. The hot air component 42 and the riveting component 43 are both disposed on the mounting plate 412. Moreover, the mounting plate 412 is mounted on the bracket 401 via the guide rail 413, which can ensure the accuracy and stability of the translation of the mounting plate 412; the hot air assembly 42 and the riveting assembly 43 are arranged side by side on the translation assembly 41 to sequentially heat and rivet the workpiece 100 on the positioning fixture 30.

[0027] In this invention, preferably, the positioning fixture 30 has two stations for positioning the workpieces 100. First, one workpiece 100 is fixed on the positioning fixture 30. Then, the workpiece 100 is moved below the riveting mechanism 40 by the rotation of the rotary table 20. Next, another workpiece 100 is fixed on the other side of the positioning fixture 30. The translation component 41 drives the hot air component 42 to heat the riveted parts on the workpiece 100 located below the riveting mechanism 40. After the heating action is completed, the translation component 41 drives... The riveting assembly 43 moves to the riveting part on the workpiece 100 (the hot air assembly 42 moves away from the position simultaneously) to perform the riveting action, completing the hot air cold riveting action of the workpiece; after the rotary table 20 rotates, it drives the workpiece 100 to move away from under the riveting mechanism 40, and simultaneously moves another workpiece 100 to under the riveting mechanism 40, repeating the above-mentioned hot air heating and riveting action; after both workpieces 100 have completed the hot air cold riveting (using the rotation of the rotary table 20), the two workpieces 100 are unloaded respectively.

[0028] This invention uses a translation component 41 to sequentially drive a hot air component 42 and a riveting component 43 to heat and rivet the parts on the workpiece 100 that need to be riveted. The heating effect of the hot air component 42 facilitates the riveting of the riveting component 43, thereby enabling the riveting action to be completed quickly and accurately, improving the accuracy and efficiency of riveting. Moreover, the cooperation between the rotating worktable 20 and the positioning fixture 30 allows two or more workpieces 100 to be loaded at one time for sequential hot air cold riveting, reducing downtime and improving processing efficiency.

[0029] The hot air assembly 42 includes a first electric cylinder 421, a first lifting plate 422, a hot air module 423, and a hot air head 424. The first electric cylinder 421 is mounted on the mounting plate 412 of the translation assembly 41. The first lifting plate 422 is slidably mounted on the mounting plate 412 and connected to the output end of the first electric cylinder 421. The hot air module 423 is mounted on the first lifting plate 422. The hot air head 424 is connected to the hot air module 423 for blowing hot air onto the workpiece 100. When the hot air assembly 42 needs to heat the workpiece 100 with hot air, the first electric cylinder 421 drives the first lifting plate 422 to move down to the corresponding position, and the hot air head 424 also moves down to be close to the workpiece 100. The hot air module 423 heats the riveted parts on the workpiece 100 with hot air through the hot air head 424.

[0030] Similarly, the riveting assembly 43 includes a second electric cylinder 431, a second lifting plate 432, and a riveting head 433. The second electric cylinder 431 is mounted on the mounting plate 412 of the translation assembly 41. The second lifting plate 432 is slidably mounted on the mounting plate 412 and located next to the first lifting plate 422, and is connected to the output end of the second electric cylinder 431. The riveting head 433 is located at the lower end of the second lifting plate 432. When the riveting assembly 43 needs to rivet the workpiece 100, the second electric cylinder 431 drives the second lifting plate 432 to move down and drives the riveting head 433 to move down, and the riveting action is completed by the downward pressing action of the riveting head 433.

[0031] Preferably, both the first lifting plate 422 and the second lifting plate 432 are mounted on the mounting plate 412 via slide rails 414, which can ensure the accuracy and stability of the vertical movement of the two plates and the components located on them.

[0032] More specifically, in combination Figure 4 As shown, the riveting joint 433 includes a fixing rod 4331 and a pressure rod 4332. The fixing rod 4331 is located at the lower end of the second lifting plate 432 and has a first through hole 4301 that penetrates its body laterally. The pressure rod 4332 has an insertion hole 4303 in the axial direction and a second through hole 4304 that penetrates its body and the insertion hole 4303 in the radial direction. The insertion hole 4303 is sleeved on the fixing rod 4331, and the pressure rod 4332 and the fixing rod 4331 are connected by a pin 4333 that passes through the first through hole 4301 and the second through hole 4303. Therefore, the pressure rod 4332 and the fixing rod 4331 can be easily disassembled and assembled. When the pressure rod 4332 needs to be replaced and maintained, or when different pressure rods 4332 (with different pressing surfaces to adapt to different riveting parts) need to be replaced, it is beneficial to quickly replace the pressure rod 4332.

[0033] Furthermore, the first through hole 4301 is a vertically extending waist-shaped hole, and the second through hole 4302 is a round hole; the side wall of the fixing rod 4331 is provided with a limiting step 4302, and the inner wall of the insertion hole 4303 is also provided with a limiting step (not shown). The lower part of the fixing rod 4331 is fitted with a spring 4334, which extends into the insertion hole 4303 so that the upper and lower ends of the spring 4334 respectively abut against a pair of limiting steps 4302, so that the pressure rod 4332 can be installed on the basis of the fixing rod 4331. At the same time, since the first through hole 4301 has a waist-shaped hole structure, the pressure rod 4332 can move relative to the fixing rod 4331, and the elastic action of the spring 4334 is used to realize the pre-pressing positioning of the pressure rod 4332, as well as the pressing action of the pressure rod 4332 after the spring 4334 is compressed.

[0034] In addition, such as Figure 1As shown, the hot air cold riveting equipment also includes a detection mechanism, which is set on the machine base 10 and includes at least a camera 50. The camera 50 can be set above the positioning fixture 30 via a support frame 501, and can visually detect the riveting effect of the workpiece 100.

[0035] Combination Figure 1 and Figure 5 As shown, the machine housing 1a includes a housing 11 and a door 12. The housing 11 is mounted on the machine base 10 and is provided with a guide rail. The door 12 includes a first lifting cylinder 121 and a door panel 122. The first lifting cylinder 121 is located inside the machine base 10. The door panel 122 is located at the output end of the first lifting cylinder 121 and can slide on the guide rail. After being driven by the first lifting cylinder 121, the door panel 122 is closed. When it is necessary to load or unload the workpiece 100, the first lifting cylinder 121 drives the door panel 122 to move upward so that the housing 11 has an opening 110 to complete the loading and unloading action. In addition, the door panel 122 is provided with a viewing window 1220 for observing the condition inside the machine housing 1a.

[0036] The housing 1a is equipped with a second lifting cylinder 141. The output end of the second lifting cylinder 141 is equipped with an inner partition 142. After the second lifting cylinder 141 drives the inner partition 142 to move down, it is used to separate the two workstations on the positioning fixture 30. Therefore, when one workpiece 100 is being heated by hot air and riveted, the heating effect of the hot air assembly 42 can be avoided from affecting the other workpiece 100. The inner partition 142 is set on the housing 11 through the guide rail and guide cylinder structure 143.

[0037] Furthermore, the door 12 and the inner partition 142 allow the components to be heated while isolating them from outside air as much as possible, quickly heating them to the specified temperature and maintaining it, which is beneficial for subsequent riveting operations.
