[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, an embodiment of the present application provides a heat riveting mechanism for a valve core of a distribution valve, comprising a workbench 1, on which a conveying mechanism 2 and a heat riveting mechanism 3 are arranged, the conveying mechanism 2 is used to move the distribution valve to one side of the heat riveting mechanism 3, and the heat riveting mechanism 3 is used to heat rivet three rivet feet on the periphery of the valve core in the distribution valve.

[0027] like Figure 2 As shown, the hot riveting mechanism 3 includes a second driving mechanism 31, a base 32, a frame 33, a lifting driving mechanism 34 and a hot riveting device 35. The base 32 is installed on the workbench 1, the second driving mechanism 31 is installed on the base 32, the driving end of the second driving mechanism 31 is connected to the frame 33, the frame 33 and the base 32 are slidably matched, the lifting driving mechanism 34 is installed at the top of the frame 33, the driving end of the lifting driving mechanism 34 passes through the frame 33 and is connected to the hot riveting device 35, and the hot riveting device 35 is slidably matched with the frame 33.

[0028] like Figure 4 As shown, the conveying mechanism 2 includes a first driving mechanism 21 and a sliding plate 22. The driving end of the first driving mechanism 21 is connected to the sliding plate 22. The sliding plate 22 is slidably matched with the workbench 1. A supporting frame 23, a rotating mechanism 24 and a jig 25 are provided on the sliding plate 22. The rotating mechanism 24 is installed on the sliding plate 22. The driving end of the rotating mechanism 24 passes through the supporting frame 23 and is connected to the jig 25. The rotating mechanism 24 is used to drive the jig 25 to rotate 180 degrees.

[0029] Specifically, the hot riveting mechanism of the valve core of the distribution valve is composed of a transmission mechanism 2 and a hot riveting mechanism 3. The distribution valve is placed in the fixture 25 of the transmission mechanism 2. The first driving mechanism 21 drives the sliding plate 22 to drive the rotating mechanism 24 and the fixture 25 to move horizontally to one side of the hot riveting mechanism 3. The second driving mechanism 31 of the hot riveting mechanism 3 drives the frame 33 to drive the hot riveting device 35 to move toward the fixture 25, so that the hot riveting device 35 is located above the fixture 25. Then the lifting driving mechanism 34 drives the hot riveting device 35 to move downward to hot-melt the three rivet feet on the periphery of the valve core, so that the valve core is fixed in the distribution valve. After the hot riveting mechanism 3 hot-melts and fixes the valve core on one side of the distribution valve, the rotating mechanism 24 drives the fixture 25 to rotate 180 degrees, and then the valve core on the other side of the distribution valve is located on one side of the hot riveting mechanism 3. The above operation is repeated, and the hot riveting mechanism 3 hot-rivets the valve core on the other side and fixes it in the distribution valve. Finally, the transmission mechanism 2 moves the distribution valve in the fixture 25 to the next working position.

[0030] The above structure, by setting the rotating mechanism 24 on the conveying mechanism 2, the rotating mechanism 24 drives the jig 25 to move. This arrangement greatly improves the hot riveting efficiency of the equipment and saves the time cost of manually rotating the jig 25.

[0031] like Figure 4 As shown, in one embodiment, the rotating mechanism 24 of the distribution valve core hot riveting mechanism includes a rotating cylinder 241, a connecting flange is provided on the support frame 23, a first bearing 242 and a second articulated bearing 243 are provided in the connecting flange, and the rotating axis of the rotating cylinder 241 passes through the first bearing 242 and the second articulated bearing 243 and is connected to the jig 25.

[0032] Specifically, since the heat riveting mechanism 3 needs to heat-smash the three riveting feet on the periphery of the valve core, the heat riveting pressure of the heat riveting mechanism 3 is increased. By arranging the first bearing 242 and the second hinge bearing 243 above the rotating cylinder 241, the bearing capacity of the rotating cylinder 241 is enhanced.

[0033] like Figure 4 As shown, in one embodiment, a limiting component 26 is provided at one end of the support frame 23 of the distribution valve core hot riveting mechanism close to the jig 25, and a limiting block 27 is provided at one end of the rotating axis of the rotating cylinder 241 close to the jig 25, and the limiting block 27 is used to cooperate with the limiting component 26 to limit the jig 25 after it rotates 180 degrees.

[0034] Specifically, when the rotating cylinder 241 drives the fixture 25 to rotate 180 degrees, the limiting component 26 will limit the limiting block 27, thereby limiting the rotating cylinder 241 from continuing to rotate.

[0035] like Figure 2 and Figure 3 As shown, in one embodiment, the heat riveting device 35 of the heat riveting mechanism of the valve core of the distribution valve includes a fixed frame 351 and a heat riveting assembly 352, the fixed frame 351 is slidably matched with the frame body 33, the heat riveting assembly 352 is installed at the bottom end of the fixed frame 351, and the fixed frame 351 is also provided with an elastic pressure plate 353 for pressing the distribution valve in the fixture 25, and the elastic pressure plate 353 is also provided with a fixing column 354 for pressing the valve core in the distribution valve.

[0036] Specifically, the elastic pressure plate 353 includes a pressure plate, a guide column, a limit column and a spring. The guide column is connected to the fixing frame 351 and the pressure plate respectively. The limit column is sleeved on the guide column. One end of the spring is against the limit column, and the other end of the spring is against the pressure plate. The fixed column 354 on the pressure plate is used to fix the valve core. When the lifting drive mechanism 34 drives the hot riveting assembly 352 to move downward to hot rivet the valve core, the elastic pressure plate 353 first presses the distribution valve into the fixture 25, and the fixed column 354 on the pressure plate presses the valve core into the distribution valve. In this way, the hot riveting assembly 352 accurately heat-seals the three rivet feet on the periphery of the valve core to accurately fix the valve core in the distribution valve.

[0037] The above arrangement facilitates accurate hot melting of the three rivet feet on the periphery of the valve core, thereby fixing the valve core in the distribution valve.

[0038] like Figure 3 As shown, in one embodiment, the hot riveting assembly 352 of the hot riveting mechanism of the valve core of the distribution valve includes a heating controller 100 and three hot riveting heads 101, the heating controller 100 is connected to the three hot riveting heads 101, the three hot riveting heads 101 are spaced apart by a distance greater than the valve core, the bottom end surface of the hot riveting head 101 is a horizontal structure, and the three hot riveting heads 101 are used to hot-melt the three rivet feet on the outside of the valve core.

[0039] Specifically, the three hot rivet heads 101 correspond to three rivet feet respectively, and the end faces of the three hot rivet heads 101 are respectively horizontal planes. The heating controller 100 heats the three hot rivet heads 101, and the hot rivet heads 101 perform heat melting on the three rivet feet. Setting the end faces of the hot rivet heads 101 as horizontal planes facilitates heat melting and leveling the rivet feet, and facilitates the installation of the coil.

[0040] like Figure 2 As shown, in one embodiment, a photoelectric sensor assembly 355 for detecting whether a valve core is placed in the distribution valve is provided on the fixing frame 351 of the heat riveting mechanism of the distribution valve core, and a heat insulation plate 356 is provided between the photoelectric sensor and the fixing frame 351.

[0041] Specifically, the first photoelectric sensor assembly 355 is used to detect whether a valve core is placed in the distribution valve. This setting can prevent the hot riveting assembly 352 from performing hot melting operation on the distribution valve without a valve core, and can promptly remind the staff to handle it.

[0042] like Figure 1 As shown, in one of the embodiments, a second photoelectric sensor 4 for detecting whether a dispensing valve is placed in the jig 25 is also provided on the workbench 1 of the dispensing valve core heat riveting mechanism.

[0043] Specifically, a second photoelectric sensor 4 is provided on the workbench 1 at the same axis position as the fixture 25, and the second photoelectric sensor 4 is used to detect whether a dispensing valve is placed in the fixture 25. When there is no dispensing valve in the fixture 25, a signal is sent in time to remind the staff to handle it.

[0044] like Figure 2 and Figure 4 As shown, in one embodiment, the first driving mechanism 21 of the heat riveting mechanism of the valve core of the distribution valve is a first screw transmission mechanism, and the second driving mechanism 31 is a second screw transmission mechanism.

[0045] Specifically, the first screw transmission mechanism includes a No. 1 motor and a No. 1 screw, the driving end of the No. 1 motor is connected to the No. 1 screw, the No. 1 screw is connected to the sliding plate 22, the No. 1 motor drives the No. 1 screw to drive the sliding plate 22 to move toward the hot riveting mechanism 3. The second screw transmission mechanism includes a No. 2 motor and a No. 2 screw, the driving end of the No. 2 motor is connected to the No. 2 screw, the No. 2 screw is connected to the frame 33, the No. 2 motor drives the No. 2 screw to drive the frame 33 to move toward the transmission mechanism 2. This arrangement facilitates the movement of the drive transmission mechanism and the hot riveting mechanism 3.

[0046] like Figure 2 As shown, in one embodiment, the lifting drive mechanism 34 of the heat riveting mechanism of the valve core of the distribution valve is an electric cylinder, and a pressure sensor 36 for detecting the pressure value is arranged between the driving end of the electric cylinder and the heat riveting device 35.

[0047] The pressure sensor 36 is convenient for testing the pressure when the lifting drive mechanism 34 drives the heat riveting assembly 352 to move downward to perform heat riveting on the distribution valve.

[0048] like Figure 2 As shown, in one of the embodiments, the frame 33 of the heat riveting mechanism of the distribution valve core is provided with a displacement sensor 37 for detecting the moving distance of the heat riveting device 35 .

[0049] The displacement sensor 37 is convenient for testing the average distance that the heat riveting device 35 moves downward multiple times to perform heat riveting on the distribution valve.

[0050] 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. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
