[0013] A method for automated processing of cold chain refrigeration equipment accessories: The specific steps of the method are: S1. Place the metal tube with a larger diameter on the side of the nozzle adjustment block without a heating device and pass it through the fixing frame. Place the metal tube with a smaller diameter on the side of the nozzle adjustment block with a heating device and pass it through the fixing frame. At this time, start the motor through the control panel so that the motor drives the first screw rod to rotate forward, so that the position of the slide remains unchanged while the fixing frame moves in the opposite direction, and at the same time, tightens the metal tube and drives the metal tube to move in the opposite direction; S2. When the fixed frame drives the metal tube with a larger diameter and the metal tube with a smaller diameter to move closer to the nozzle adjusting block, the metal tube with a smaller diameter is heated by the heating device of the nozzle adjusting block. At the same time, the nozzle adjusting block is squeezed by the fixed frame, so that the port of the metal tube with a smaller diameter gradually expands until the metal tube with a larger diameter contacts the nozzle adjusting block and cannot move. At this time, the inner diameter of the port of the metal tube with a smaller diameter is the same as that of the port of the metal tube with a larger diameter, and finally welded.

At this time, the inner diameter of the port of the metal tube with a smaller diameter is the same as that of the port of the metal tube with a larger diameter, and the diameter of the metal tube connection is adjusted, so that the metal tubes of the two diameters can be welded together. Therefore, the connection of the metal tubes of the two diameters does not require the participation of connectors, which not only reduces the investment in material costs, but also avoids adjusting the size of the connectors.

[0015] 2. The present invention drives one end of the first transmission belt to rotate through the longitudinal groove on the first screw rod, so that the other end of the first transmission belt drives the active bevel gear to rotate, so that the driven bevel gear meshing with the active bevel gear drives the second transmission belt to rotate, so that the second screw rod on the second transmission belt rotates, so that the longitudinal groove on the second screw rod drives the active gear to rotate, so that the first transmission gear meshing with the active gear drives the driven gear to rotate, and then the lever on the driven gear drives the planetary bevel gear to revolve, so that the planetary bevel gear synchronously drives the auxiliary bevel gear and the transmission bevel gear to rotate, so that the transmission bevel gear drives the second transmission gear to rotate through the transmission shaft, so that the second transmission gear drives the gear ring to rotate, so that the gear ring meshing with the gear ring The planetary gears meshing with the ring drive the worm to rotate, which in turn causes the worm to drive the worm wheel to rotate, so that the worm wheel drives the third screw to rotate through the longitudinal groove on the third screw, and the third screw is meshed and sleeved with the fixed frame, so that the third screw rotates and gathers toward the central axis of the fixed frame, so that the clamping block on the third screw gathers toward the central axis of the fixed frame, so that the clamping block clamps the outer surface of the metal pipe, thereby achieving the purpose of tightening the metal pipe. While tightening the metal pipe, the pipe diameter at the connection of the metal pipe can be adjusted, so that the automated processing cycle of refrigeration equipment accessories is shortened, and at the same time, there is no need to separately control the tightening of the metal pipe and the adjustment of the pipe diameter, so that there is no need for multiple control elements to participate in the processing process, which not only reduces the cost but also avoids the difficulty of wiring.

[0016] The first transmission belt on the first screw rod is reversed, so that the fixed frame moves in the reverse direction. At the same time, since the embedded rod is engaged with the embedded hole, the fixed frame can continuously fix the metal pipe until the embedded rod is separated from the embedded hole. At this time, the metal pipe is also separated from the pipe mouth adjusting block. As the fixed frame continues to move in the reverse direction, the clamping rod is also separated from the clamping hole, so that the moving block is again engaged with the external thread of the first screw rod under the rebound of the spring, so that the moving block is translated in the opposite direction under the drive of the first screw rod, and the slide is driven to engage with the external thread of the first screw rod, so that the slide is translated under the reversal of the first screw rod, so as to achieve the purpose of translating the metal pipe, thereby facilitating the subsequent docking and welding of the metal pipe, further improving the degree of automated processing, and at the same time, without the participation of a large number of control components.

[0024] Specifically, in the process of adjusting the diameter of the metal pipe port, when the second screw rod 16 rotates, the slider 34 engaged with the second screw rod 16 translates under the limit of the slide groove 5, so that the sliders 34 at both ends of the slide 4 move toward each other, so that the fixing frame 35 on the slider 34 moves toward each other, and then the fixing frame 35 drives the metal pipe with larger diameter and the metal pipe with smaller diameter to move closer to the pipe mouth adjusting block 6, so that the metal pipe with smaller diameter is heated by the heating device of the pipe mouth adjusting block 6, and at the same time, the pipe mouth adjusting block 6 is squeezed under the drive of the fixing frame 35, so that the port of the metal pipe with smaller diameter gradually expands until the metal pipe with larger diameter contacts with the pipe mouth adjusting block 6 and cannot move.

[0027] Specifically, in the process of adjusting the diameter of the metal tube port while tightening the metal tube, the longitudinal groove on the first screw rod 8 drives one end of the first transmission belt 12 to rotate, so that the other end of the first transmission belt 12 drives the active bevel gear 13 to rotate, so that the driven bevel gear 14 meshing with the active bevel gear 13 drives the second transmission belt 15 to rotate, so that the second screw rod 16 on the second transmission belt 15 rotates, so that the longitudinal groove on the second screw rod 16 drives the active gear 17 to rotate, so that the first transmission gear 18 meshing with the active gear 17 drives the driven gear 19 to rotate, and then the lever 20 on the driven gear 19 drives the planetary bevel gear 21 to revolve, so that the planetary bevel gear 21 synchronously drives the auxiliary bevel gear 22 and the transmission bevel gear 23 to rotate, so that the transmission bevel gear 23 drives the second transmission gear 26 to rotate through the transmission shaft 25, so that the second The transmission gear 26 drives the gear ring 28 to rotate, so that the planetary gear 29 meshing with the gear ring 28 drives the worm 30 to rotate, and then the worm 30 drives the worm wheel 31 to rotate, so that the worm wheel 31 drives the third screw rod 32 to rotate through the longitudinal groove on the third screw rod 32, and the third screw rod 32 is meshed and sleeved with the fixing frame 35, so that the third screw rod 32 rotates while gathering toward the central axis of the fixing frame 35, so that the clamping block 33 on the third screw rod 32 gathers toward the central axis of the fixing frame 35, so that the clamping block 33 clamps the outer surface of the metal pipe, so as to achieve the purpose of fastening the metal pipe. While fastening the metal pipe, the pipe diameter at the connection of the metal pipe can be adjusted, so that the automated processing cycle of refrigeration equipment accessories is shortened, and at the same time, there is no need to separately control the fastening of the metal pipe and the adjustment of the pipe diameter, so that there is no need for multiple control elements to participate in the processing process, which not only reduces the cost but also avoids the difficulty of wiring.

[0028] Example 3 See also Figure 3 , Figure 6 and Figure 8 The present invention provides a technical solution: an automated processing device and method for cold chain refrigeration equipment accessories, wherein an embedding rod 39 is fixedly connected to the top surface of the slide 4, the embedding rod 39 is embedded and sleeved with the embedding hole 27, and the embedding rod 39 is slidably sleeved with the fixing frame 35, and one end of the connecting rod 36 is fixedly connected to the bottom surface of the fixing frame 35, and a clamping rod 37 is slidably sleeved on the other end of the connecting rod 36, and a positioning ring 38 is fixedly sleeved on the outer surface of the clamping rod 37, and two positioning rings 38 are provided, and the two positioning rings 38 are located on both sides of the connecting rod 36.

[0029] Specifically, in the process of translating the metal pipe, the motor 7 is reversed by the control panel 2, so that the first screw rod 8 on the motor 7 is reversed. At this time, since the clamping rod 37 is engaged with the clamping hole 10, the position of the moving block 9 remains unchanged, so that the reversal of the first screw rod 8 cannot drive the moving block 9 to translate, so that the position of the slide 4 remains unchanged, and the first transmission belt 12 on the first screw rod 8 is reversed, so that the fixed frame 35 moves in the reverse direction. At the same time, since the embedded rod 39 is engaged with the embedded hole 27, the fixed frame 35 can continuously fix the metal pipe until the embedded rod 39 is separated from the embedded hole 27. At this time, the metal pipe is The tube is also separated from the tube mouth adjustment block 6, and as the fixed frame 35 continues to move backward, the clamping rod 37 is also separated from the clamping hole 10, so that the moving block 9 is re-engaged with the external thread of the first screw rod 8 under the rebound of the spring 11, so that the moving block 9 is driven by the first screw rod 8 to translate in the opposite direction, and drives the slide 4 to engage with the external thread of the first screw rod 8, so that the slide 4 translates under the reversal of the first screw rod 8, thereby achieving the purpose of translating the metal tube, thereby facilitating the subsequent docking and welding of the metal tube, further improving the degree of automated processing, and at the same time eliminating the need for a large number of control components.

[0030] The working principle and use process of the present invention are as follows: when it is necessary to process the accessories of the refrigeration equipment, the metal pipe with a larger diameter is placed on the side of the pipe mouth adjusting block 6 without the heating device and passes through the fixing frame 35, and the metal pipe with a smaller diameter is placed on the side of the pipe mouth adjusting block 6 with the heating device and passes through the fixing frame 35. At this time, the motor 7 is started through the control panel 2, so that the motor 7 drives the first screw rod 8 to rotate forward, so that the slide 4 on the first screw rod 8 is disengaged from the external thread on the first screw rod 8, and at the same time, the moving block 9 is driven by the first screw rod 8 to shrink into the slide 4, squeeze the spring 11 and disengage from the external thread on the first screw rod 8, so that the position of the slide 4 remains unchanged when the first screw rod 8 continues to rotate forward; During the continuous forward rotation of the first screw rod 8, the longitudinal groove on the first screw rod 8 drives one end of the first transmission belt 12 to rotate, so that the other end of the first transmission belt 12 drives the active bevel gear 13 to rotate, so that the driven bevel gear 14 meshing with the active bevel gear 13 drives the second transmission belt 15 to rotate, so that the second screw rod 16 on the second transmission belt 15 rotates, so that the longitudinal groove on the second screw rod 16 drives the active gear 17 to rotate, so that the first transmission gear 18 meshing with the active gear 17 drives the driven gear 19 to rotate, and then the lever 20 on the driven gear 19 drives the planetary bevel gear 21 to revolve, so that the planetary bevel gear 2 The auxiliary helical gear 22 and the transmission helical gear 23 are synchronously driven to rotate, so that the transmission helical gear 23 drives the second transmission gear 26 to rotate through the transmission shaft 25, so that the second transmission gear 26 drives the gear ring 28 to rotate, so that the planetary gear 29 meshing with the gear ring 28 drives the worm 30 to rotate, and then the worm 30 drives the worm wheel 31 to rotate, so that the worm wheel 31 drives the third screw rod 32 to rotate through the longitudinal groove on the third screw rod 32, and the third screw rod 32 is meshed and sleeved with the fixing frame 35, so that the third screw rod 32 rotates while converging toward the central axis of the fixing frame 35, so that the clamping block 33 on the third screw rod 32 converges toward the central axis of the fixing frame 35 The clamping block 33 clamps the outer surface of the metal tube to achieve the purpose of tightening the metal tube. When the second screw rod 16 rotates, the slider 34 engaged with the second screw rod 16 translates under the limit of the slide groove 5, so that the sliders 34 at both ends of the slide 4 move towards each other, so that the fixing frame 35 on the slider 34 moves towards each other, and then the fixing frame 35 drives the metal tube with a larger diameter and the metal tube with a smaller diameter to move closer to the nozzle adjusting block 6, so that the metal tube with a smaller diameter is heated by the heating device of the nozzle adjusting block 6. At the same time, the nozzle adjusting block 6 is squeezed under the drive of the fixing frame 35, so that the port of the metal tube with a smaller diameter gradually expands until the metal tube with a larger diameter is closed. It is in contact with the pipe opening adjustment block 6 and cannot move. At this time, the inner diameter of the metal pipe port with a smaller pipe diameter is the same as that of the metal pipe port with a larger pipe diameter. The pipe diameter at the connection of the metal pipes is adjusted, and the metal pipes of two pipe diameters can be welded together. Therefore, the connection of the metal pipes of two pipe diameters does not require the participation of connectors, which not only reduces the investment in material costs, but also avoids adjusting the size of the connectors. In summary, the pipe diameter at the connection of the metal pipes can be adjusted while the metal pipes are tightened, so that the automatic processing cycle of the refrigeration equipment accessories is shortened. At the same time, there is no need to separately control the tightening of the metal pipe and the adjustment of the pipe diameter, so that multiple control elements do not need to participate in the processing process, which not only reduces the cost but also avoids the difficulty of wiring. In the above process, when the clamp block 33 first tightens the metal tube, the transmission bevel gear 23 will not be able to rotate. At this time, the planetary bevel gear 21 indirectly driven by the second screw rod 16 rotates while revolving, so that the rotation of the second screw rod 16 is not affected by the tightening of the metal tube, so that the metal tube can still move in the opposite direction. In the process of the metal tube and the fixing frame 35 moving in the opposite direction, the embedding rod 39 will be inserted into the fixing frame 35 and fit into the embedding hole 27 on the transmission shaft 25. At the same time, the connecting rod 36 will drive the clamping rod 37 to insert into the slide 4 and clamp with the clamping hole 10 on the moving block 9. When the diameter of the metal tube is adjusted, the motor 7 is reversed by the control panel 2, so that the first screw 8 on the motor 7 is reversed. At this time, since the clamping rod 37 is engaged with the clamping hole 10, the position of the moving block 9 remains unchanged, so that the reversal of the first screw 8 cannot drive the moving block 9 to move horizontally, so that the position of the slide 4 remains unchanged, and the first transmission belt 12 on the first screw 8 is reversed, so that the fixing frame 35 moves in the reverse direction. At the same time, since the embedded rod 39 is engaged with the embedded hole 27, the fixing frame 35 can continuously fix the metal tube until the embedded rod 39 is separated from the embedded hole 27. At this time, the metal tube is also It is separated from the pipe mouth adjustment block 6, and as the fixing frame 35 continues to move backward, the clamping rod 37 is also separated from the clamping hole 10, so that the moving block 9 is re-engaged with the external thread of the first screw rod 8 under the rebound of the spring 11, so that the moving block 9 is driven by the first screw rod 8 to translate in the opposite direction, and drives the slide 4 to engage with the external thread of the first screw rod 8, so that the slide 4 is translated under the reversal of the first screw rod 8, so as to achieve the purpose of translating the metal pipe, thereby facilitating the subsequent docking and welding of the metal pipe, further improving the degree of automated processing, and completing the operation without the participation of a large number of control components.
