[0028] like Figure 1 and Figure 7 As shown, an embodiment of the present application provides a heat riveting mechanism for a distribution valve, comprising a workbench 1, on which a jig 2, a conveying mechanism 3, a pressing mechanism 4 and a heat riveting mechanism 5 are arranged, the jig 2 is used to place a distribution valve 6 with a plug 63 installed, the driving end of the conveying mechanism 3 is connected to the jig 2, the conveying mechanism 3 is used to convey the jig 2 to the working positions of the pressing mechanism 4 and the heat riveting mechanism 5, the pressing mechanism 4 is used to press the distribution valve 6 into the jig 2 and press the plug 63 onto the distribution valve 6, the heat riveting mechanism 5 is used to perform heat riveting on the sensor 61 and the valve core 62 components in the distribution valve 6,

[0029] like Figure 2 As shown, the pressing mechanism 4 includes a support frame 41, a vertically mounted first cylinder 42 and a pressing assembly 43. The first cylinder 42 is fixed on the support frame 41, and the driving end of the first cylinder 42 is connected to the pressing assembly 43. The pressing assembly 43 and the support frame 41 are slidably matched through a sliding assembly.

[0030] like Figure 2 As shown, the clamping assembly 43 includes a fixed component 431, an elastic component 432, a No. 1 clamping block 433 and a No. 2 clamping block 434. The elastic component 432 is installed on the fixed component 431, and the elastic component 432 is connected to the No. 1 clamping block 433. The No. 1 clamping block 433 is provided with a pressure head 435, and the pressure head 435 is provided with a through hole for accommodating the plug of the sensor 61. The No. 2 clamping block 434 is connected to the fixed component 431. The No. 1 clamping block 433 is used to clamp the distribution valve 6 in the fixture 2, and the No. 2 clamping block 434 is used to clamp the plug 63 onto the distribution valve 6.

[0031] Specifically, the distribution valve hot riveting mechanism is composed of a jig 2, a conveying mechanism 3, a pressing mechanism 4 and a hot riveting mechanism 5. First, the distribution valve 6 with the installed plug 63 in the jig 2 is moved to one side of the pressing mechanism 4 through the conveying mechanism 3. The first cylinder 42 of the pressing mechanism 4 drives the pressing assembly 43 to move toward the distribution valve 6 in the jig 2, wherein the first pressing block 433 of the pressing assembly 43 presses the distribution valve 6 in the jig 2, and the plugs of the sensor 61 in the distribution valve 6 are respectively extended into the through holes of the pressing head 435, and the pressing head 435 presses the sensor 61 against the housing. In the embodiment, the position of the second pressure block 434 is higher than the first pressure block 433. When the first pressure block 433 presses the housing of the distribution valve 6 into the jig 2, the second pressure block 434 presses the plug 63 flat on the housing of the distribution valve 6. Then, the conveying mechanism 3 conveys the jig 2 to one side of the hot riveting mechanism 5. The hot riveting mechanism 5 performs hot melting on the four retaining petals 611 on the outside of the sensor 61 in the distribution valve 6 to fix the sensor 61 in the housing. The hot riveting mechanism 5 then performs hot melting on the four rivet feet 621 on the outside of the valve core 62 to fix the valve core 62 and the silicone sleeve in the housing. Among them, the elastic component 432 includes a limit plate, two guide pillars and two springs. The two guide pillars are connected to the fixed component 431 through a guide sleeve. One end of the two guide pillars is connected to the limit plate, and the other end of the two guide pillars is connected to the first pressure block 433. One end of the spring abuts against the fixed component 431, and the other end of the spring abuts against the first pressure block 433. When the first pressing block 433 presses the distribution valve 6 , the spring acts as a buffer force on the first pressing block 433 .

[0032] In the above structure, the quality rate of the product after hot riveting is greatly improved by providing the pressing mechanism 4. The working efficiency of the whole hot riveting is also improved by the cooperation between the conveying mechanism 3, the pressing mechanism 4 and the hot riveting mechanism 5.

This arrangement facilitates driving the hot riveting assembly 55 to perform hot riveting on the sensor 61 and the valve core 62 in the housing.

[0035] like Figure 4 As shown, in one embodiment, the heat riveting assembly 55 of the heat riveting mechanism of the distribution valve includes a fixed plate 551 and a heat riveting controller 552, the fixed plate 551 is slidably matched with the fixed frame 52, the heat riveting controller 552 is provided with a first heat riveting component 553 and a second heat riveting component 554, and an elastic component 555 is provided between the first heat riveting component 553 and the fixed plate 551.

When the transmission mechanism 3 moves the distribution valve 6 to one side of the hot riveting mechanism 5, the second cylinder 54 drives the fixed plate 551 to drive the first hot riveting component 553 to move to the top of the valve core 62 according to the position of the valve core 62 in the shell, and then the electric cylinder drives the fixed frame 52 to drive the first hot riveting component 553 to move downward, and the elastic component 432 presses the valve core 62. The first hot riveting component 55 performs hot melting on the four rivet feet 621 on the outside of the valve core 62, fixes the valve core 62 and the silicone cap in the shell, and the elastic component 432 plays a buffering role on the valve core 62. After the hot melt is completed, the second air cylinder 54 cooperates with the electric cylinder to move the second hot riveting component 554 horizontally and downward to the sensor 61, and hot melts the four retaining petals 611 on the outside of the sensor 61 to fix the sensor 61 in the housing. Among them, the elastic component 432 includes a pressure plate, two guide pillars, two springs and two limit pillars. The two guide pillars pass through the fixed plate 551 and are connected to the pressure plate. The limit pillar passes through the fixed plate 551 and is sleeved on the guide pillar.

The four independently arranged rivet pins 001 facilitate the rapid heat-melting of the four rivet pins 621 of the valve core 62.

[0040] like Figure 5As shown, in one embodiment, the second heat riveting component 554 of the heat riveting mechanism of the distribution valve is a hollow cylinder 002, and a notch is provided on the side of the cylinder 002 close to the shell. The cylinder 002 is used to be mounted on the sensor 61 to perform heat melting on the four baffles 611 on the outside of the sensor 61.

[0041] Specifically, the cylinder 002 is sleeved on the sensor 61, and a notch is provided on one side of the cylinder 002 close to the shell. This arrangement can prevent the cylinder 002 from contacting the shell and affecting the shell.

[0043] Specifically, the linear module 31 drives the sliding plate 32 to move horizontally, and the sliding plate 32 drives the fixture 2 to move. This arrangement facilitates the transfer of the distribution valve 6 in the fixture 2.

[0044] like Figure 1 As shown, in one embodiment, a first sensor assembly 11 is provided on one side of the workbench 1 of the distribution valve heat riveting mechanism close to the conveying mechanism 3 , and the first sensor assembly 11 is used to detect whether the distribution valve 6 and the plug 63 have been installed on the fixture 2 .

[0048] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
