[0002] A gas pressure reducing valve comprises a valve bottom cup assembly and a valve stem assembly rotatably connected to the inner cavity of the valve bottom cup assembly. The valve stem assembly can close the inner cavity of the valve bottom cup assembly and the air inlet of the air inlet pipe, so as to cut off the gas from entering the inner cavity of the valve bottom cup assembly. Figure 4 The valve stem assembly includes a valve stem member and a rotating rod member that passes through a hole in the valve stem member. The rotating rod member is a core component of the valve stem assembly that realizes rotational connection to the inner cavity of the valve bottom cup assembly.

[0003] In the existing technology, the work of installing the rotating rod on the valve stem needs to be completed manually by the assembler. Specifically, the assembler needs to take the rotating rod, align the perforation hole and insert the rotating rod before completing the work of installing the rotating rod on the valve stem. Among them, since the dimensions of the rotating rod and the perforation are relatively small, the problems that exist in the process of manually installing the rotating rod on the valve stem are: 1. The probability of material loss during the material removal process of the rotating rod is high; 2. The process of aligning the perforation hole and inserting the rotating rod is laborious and requires a high labor intensity for the assembler. Utility Model Content

[0036] Reference Figures 1 to 3 The embodiment of the present invention is a rod insertion mechanism, which includes a frame 100, a material storage and conveying component 200, a moving alignment component 300 and a pushing and wearing component 400.

[0037] The storage and conveying assembly 200 is provided on the frame 100. The storage and conveying assembly 200 is provided with an abutment block 221 and a feeding channel 222 extending in the front and rear directions. The feeding channel 222 has an upwardly facing opening 222A. The abutment block 221 is located in front of the outlet of the feeding channel 222. A material taking gap S is provided between the outlet of the feeding channel 222 and the abutment block 221. The storage and conveying assembly 200 can store the rotating rod 720 and can drive the rotating rod 720 to move in the feeding channel 222 to abut against the abutment block 221, so that the front end of the rotating rod 720 is located in the material taking gap S and the rear end is located in the feeding gap S. Channel 222, the movable alignment component 300 is arranged on the frame 100, the movable alignment component 300 can clamp the front end of the rotating rod 720 through the material picking gap S, and can move the clamped rotating rod 720 away from the feeding channel 222 through the opening 222A, and then move it to a preset position to align with the through hole 711 of the valve stem 710, and the pushing and wearing component 400 is arranged on the movable alignment component 300. The pushing and wearing component 400 can push the rear end of the rotating rod 720 clamped by the movable alignment component 300, so that the front end of the aligned rotating rod 720 moves through the through hole 711 of the valve stem 710.

[0038] After the opening 222A is opened, the locking cam 720 is unlocked, and the locking cam 720 is unlocked, so that the locking cam 720 is unlocked. The front end of the rotating rod 720 moves through the through-hole 711 of the valve stem 710. It can be seen that the material storage and conveying component 200, the moving alignment component 300 and the pushing and inserting component 400 of the rod insertion mechanism of the present application cooperate with each other, which can replace the manual work of picking up materials, aligning the through-hole 711 and pushing and inserting the rotating rod 720. Therefore, on the one hand, compared with the traditional manual material picking process, the mechanical clamping and material picking process realized by the moving alignment component 300 has a lower probability of material loss; on the other hand, the process of aligning the through-hole 711 and the action of inserting the rotating rod 720 do not require manual participation, so the labor intensity of the assembler can be reduced.

[0039] The storage and conveying assembly 200 includes a vibration plate 210 and a direct vibration feeder 220 .

[0040] Reference Figure 1The vibration disk 210 is arranged on the frame 100, and the vibration disk 210 can store the rotating rod 720. The direct vibration feeder 220 is arranged on the frame 100. The direct vibration feeder 220 is provided with the above-mentioned abutment block 221 and the above-mentioned feeding channel 222. The direct vibration feeder 220 is connected to the vibration disk 210, wherein the direct vibration feeder 220 and the vibration disk 210 can work together to drive the rotating rod 720 on the vibration disk 210 to move to the feeding channel 222, and move in the feeding channel 222 to abut against the abutment block 221.

[0041] In some embodiments, the material storage and conveying assembly 200 only includes a vibration plate 210, which is arranged on the frame 100. The vibration plate 210 can store the rotating rod 720. The vibration plate 210 is provided with the above-mentioned abutment block 221 and the above-mentioned material delivery channel 222. The vibration plate 210 can work to drive the rotating rod 720 on the vibration plate 210 to move to the material delivery channel 222, and move in the material delivery channel 222 to abut against the abutment block 221.

[0042] In this embodiment, referring to Figure 1 and Figure 2 The direct vibration feeder 220 is provided with a baffle 500, which is located above the feeding channel 222 to close a portion of the opening 222A. The movable alignment component 300 can move the clamped rotating rod 720 away from the feeding channel 222 through the other portion of the opening 222A.

[0043] It is understandable that when the rotating rod 720 moves to abut against the abutting block 221 in the feeding channel 222 , the size of the rear end portion of the rotating rod 720 located in the feeding channel 222 corresponds to the size of the other partial opening 222A.

[0044] Through the above structure and the setting of the baffle 500 , the rotating rod 700 on the feeding channel 222 can be prevented from escaping through the above-mentioned opening 222A, thereby improving the stability of the rotating rod 700 when moving in the feeding channel 222 .

[0045] The movable alignment assembly 300 includes a first driving member 310 , a mounting bracket 320 , a second driving member 330 and a clamping member 340 .

[0046] Reference Figure 1 and Figure 3The first driving member 310 is arranged on the frame 100, the mounting frame 320 is arranged on the first driving member 310, the pushing and wearing assembly 400 is arranged on the rear side of the mounting frame 320, the second driving member 330 is arranged on the front side of the mounting frame 320, and the clamping member 340 is arranged on the second driving member 330, wherein the clamping member 340 can clamp the front end of the rotating rod member 720 through the material taking gap S, the first driving member 310 can drive the clamping member 340 to move in the front and rear directions, and the second driving member 330 can drive the clamping member 340 to move in the up and down directions, so as to move the clamped rotating rod member 720 away from the material delivery channel 222 through the above-mentioned other part of the opening 222A, and then move it to a preset position to align with the through hole 711 of the valve stem member 710.

[0047] In this embodiment, the first driving member 310 and the second driving member 330 are both configured as cylinders, and the clamping member 340 is configured as a pneumatic clamping jaw. Of course, in some embodiments, the first driving member 310 and the second driving member 330 are both configured as electric push rods, etc., and the clamping member 340 is configured as an electric clamping jaw, etc.

[0048] The pushing and wearing assembly 400 includes a third driving member 410 , a fourth driving member 420 and a pushing member 430 .

[0049] Reference Figure 1 and Figure 3 The third driving member 410 is arranged on the rear side of the mounting bracket 320, the fourth driving member 420 is arranged on the third driving member 410, and the pushing member 430 is arranged on the fourth driving member 420, wherein the third driving member 410 can drive the pushing member 430 to move downward so that the pushing member 430 is at the same height as the rotating rod member 720 clamped by the clamp member 340, and the fourth driving member 420 can drive the pushing member 430 to move forward so that the pushing member 430 pushes the rear end portion of the rotating rod member 720 clamped by the clamp member 340 at the same height as the third driving member 410.

[0050] It is understandable that the third driving member 410 can drive the pushing member 430 to move upward, and the fourth driving member 420 can drive the pushing member 430 to move backward to prevent the clamping member 340 from passing through the material removal gap S to clamp the front end of the rotating rod 720.

[0051] In this embodiment, referring to Figure 1 The frame 100 is provided with a fixture 110 and a pressing assembly 600 . The fixture 110 can accommodate the valve stem 710 , and the pressing assembly 600 can press the valve stem 710 on the fixture 110 .

[0052] With the above structure, the pressing assembly 600 can press the valve stem 710 on the jig 110 to reduce the probability of the valve stem 710 detaching upward from the jig 110 when the rotating rod 720 penetrates the through hole 711 .

[0053] The pressing assembly 600 includes a fifth driving member 610 and a pressing member 620 .

[0054] Reference Figure 1 The fifth driving member 610 is provided on the frame 100 , and the pressing member 620 is provided on the fifth driving member 610 , wherein the fifth driving member 610 can drive the pressing member 620 to rotate so that the pressing member 620 presses the valve stem member 710 on the fixture 110 .

[0055] It is understandable that the fifth driving component 610 can also drive the pressing component 620 to rotate, so that the pressing component 620 avoids the valve stem component 710 and is placed on the fixture 110 .

[0056] In this embodiment, the fifth driving member 610 is configured as a rotary cylinder. Of course, in some embodiments, the fifth driving member 610 can be configured as a telescopic cylinder. The fifth driving member 610 can drive the pressing member 620 to move in the vertical direction to avoid the valve stem 710 from being placed on the jig 110, or to press the valve stem 710 against the jig 110.

[0057] In summary, refer to Figure 1 The working process of the rod insertion mechanism is as follows: 1. The straight vibration feeder 220 and the vibration plate 210 work together to drive the rotating rod 720 on the vibration plate 210 to move to the feeding channel 222, and move to abut against the abutment block 221 in the feeding channel 222; 2. The clamping member 340 clamps the front end of the rotating rod 720 through the material taking gap S; 3. The second driving member 330 drives the clamping member 340 to move in the up and down direction, and the first driving member 310 drives the clamping member 340 to move in the front and back direction, so as to move the clamped rotating rod 720 away from the feeding channel 222 through the above-mentioned other part of the opening 222A and move it to the fixture 1 10 to align with the through-hole 711 of the valve stem member 710; 4. the fifth driving member 610 drives the pressing member 620 to rotate, so that the pressing member 620 presses the valve stem member 710 on the jig 110; 5. the third driving member 410 drives the pushing member 430 to move downward, so that the pushing member 430 is at the same height as the rotating rod member 720 clamped by the clamp member 340; 6. the fourth driving member 420 drives the pushing member 430 to move forward, so that the pushing member 430 pushes the rear end portion of the rotating rod member 720 clamped by the clamp member 340 at the same height as the rotating rod member 720, so that the front end portion of the aligned rotating rod member 720 moves through the through-hole 711 of the valve stem member 710.

[0058] The present invention also provides a valve stem assembly installation device, which includes the above-mentioned rod insertion mechanism. Through the above-mentioned structure, the work of taking out the rotating rod 720, aligning the hole 711, and pushing and inserting can be automatically achieved.

[0059] Of course, the present invention is not limited to the above-mentioned embodiments.
