[0033] To make the above objects, features and advantages of the present invention more obvious and understandable, the specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0034] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0035] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or selectively exclusive embodiments from other embodiments.

[0036] Embodiment 1

[0037] Refer to Figures 1 to 7, which is the first embodiment of the present invention. This embodiment provides an integrated device for necking, chamfering, and cutting the pipeline of a refrigeration device, which includes a support assembly 100, comprising a chassis 101, a necking machine 102 and a chamfering machine 103 arranged on the surface of the chassis 101, and a slide rail 104 arranged on the surface of the chassis 101 for the necking machine 102 and the chamfering machine 103 to slide;

[0038] A clamping assembly 200, including a first rotating disk 201 rotatably connected to the chassis 101, a first chute 201a arranged inside the first rotating disk 201, a second rotating disk 202 arranged on the surface of the first rotating disk 201, a second chute 202a arranged inside the second rotating disk 202, a clamping block 203 arranged on the surface of the first rotating disk 201 away from the second rotating disk 202, and a slide rod 204 slidably connected to the clamping block 203;

[0039] A limiting cylinder 203a arranged on the outer wall of the clamping block 203 and capable of sliding inside the first chute 201a and the second chute 202a, a sliding cylinder 205 connected to the first rotating disk 201 and the second rotating disk 202, and a hose 206 connected between the sliding cylinder 205 and the limiting cylinder 203a;

[0040] A piston 207 arranged inside the sliding cylinder 205.

[0041] Among them, the chassis 101 adopts a cavity box body, and contains some other equipment required for processing inside; the upper surface of the chassis 101 is installed with a necking machine 102 and a chamfering machine 103. The necking machine 102 and the chamfering machine 103 can adopt the equipment for copper pipe processing on the market, which is the prior art here and will not be elaborated; at the same time, two necking machines 102 and two chamfering machines 103 are symmetrically arranged on the surface of the box body 101; the necking machine 102 and the chamfering machine 103 are arranged on the slide rail 104, so that the positions of the necking machine 102 and the chamfering machine 103 can be adjusted.

[0042] The first rotating disk 201 is rotatably installed on the upper surface of the chassis 101. A second rotating disk 202 is installed on the lower surface of the first rotating disk 201, and the second rotating disk 202 is rotatably connected to the chassis 101; the first chute 201a penetrates the first rotating disk 201, and the second chute 202a penetrates the second rotating disk 202, and as Figure 7 shown, the first chute 201a is a vertical chute, and the second chute 202a is an arc chute; a clamping block 203 is installed on the upper surface of the first rotating disk 201, as Figure 5As shown, the clamping block 203 is a sector structure and a cavity structure. A limiting cylinder 203a is fixedly installed on the lower surface of the clamping block 203. The limiting cylinder 203a passes through the first sliding groove 201a and the second sliding groove 202a. When the second rotating disk 202 rotates, the second sliding groove 202a will push the limiting cylinder 203a to slide along the inner wall of the second sliding groove 202a. At the same time, due to the limitation of the first sliding groove 201a, the limiting cylinder 203a slides along the inner wall of the first sliding groove 201a. Therefore, the clamping blocks 203 will approach each other. If the second rotating disk 202 rotates in the reverse direction, the clamping blocks 203 will move away from each other. Slide rods 204 are slidably installed on both side surfaces of the sector-shaped clamping blocks 203, and are arranged in a horizontal and vertical array with multiple ones, and the lengths of the slide rods 204 are different, forming an inner concave arc groove as shown in Figure 6 This design has the advantage that when the second rotating disk 202 rotates, it will cause the clamping blocks 203 to approach each other. Since the copper tube is a cylindrical structure, the outer wall surface will preferentially slide into the inner concave arc groove, and then the clamping blocks 203 approach each other to clamp the copper tube.

[0043] Furthermore, in order to make the slide rod 204 fit the surface of the copper tube more closely, a hose 206 is connected to the limiting cylinder 203a, and the other end is connected to a sliding cylinder 205. A sliding piston 207 is provided inside the sliding cylinder 205. One end of the sliding cylinder 205 close to the piston 207 is open, that is, the piston 207 will not be unable to slide due to air pressure. At the same time, the sliding cylinder 205 is connected to the first rotating disk 201 and the second rotating disk 202. In this solution, the sliding cylinder 205 passes through the second rotating disk 202 but does not pass through the first rotating disk 201. This design has the advantage that the sliding cylinder 205 is fixedly connected to the second rotating disk 202. When the sliding cylinder 205 rotates, it simultaneously pushes the clamping blocks 203 to start approaching each other. Then the slide rods 204 start to contact the outer surface of the copper tube and start to squeeze the copper tube. Then the slide rods 204 start to move into the clamping blocks 203. Then the gas inside the clamping blocks 203 starts to flow into the sliding cylinder 205 and starts to push the piston 207 to slide. Then the piston 207 abuts against the first rotating disk 201. Then the slide rods 204 stop sliding and clamp the copper tube. Then, according to requirements, control the necking machine 102 or the chamfering machine 103 to process the copper tube. If both necking and chamfering are required, the sliding cylinder 205 can be rotated to adjust the clamped copper tube by 90° and align it with the necking machine 102 or the chamfering machine 103, and then process it. If cutting is to be performed, a truss can be set above the chassis 101, and a hydraulic system is used on the truss to control the movement and lifting of the cutting machine. Then use the clamping assembly 200 to clamp the copper tube, and then use the hydraulic system to control the lifting of the cutting machine to cut the corresponding position. This existing technology is relatively mature and will not be elaborated too much.

[0044] Embodiment 2

[0045] Refer to Figures 1 to 8, which is the second embodiment of the present invention. The difference from the first embodiment is that four clamping blocks 203 are arranged in an array.

[0046] Among them, as Figure 2 shown, four clamping blocks 203 are arranged on the surface of the first rotating disk 201. The advantage of this design is that it can form a horizontal clamping and a vertical clamping. As Figure 1 shown, if only chamfering is required, it can be clamped horizontally, so that the first rotating disk 201 does not need to be rotated, which can improve the processing efficiency.

[0047] Preferably, a plurality of first moving channels 203b for the sliding rod 204 to slide are provided inside the clamping block 203, and the two first moving channels 203b are connected by a first air passage 203b-1; a receiving groove 203c is provided inside the clamping block 203, and the first moving channel 203b and the receiving groove 203c are connected by a second air passage 203c-1;

[0048] a first elastic member 203d is provided inside the first moving channel 203b;

[0049] the receiving groove 203c is connected to the sliding cylinder 205 through a hose 206.

[0050] Among them, as Figure 4 shown, a plurality of first moving channels 203b are arranged in an array inside the clamping block 203. The sliding rod 204 slides along the inner wall of the first moving channel 203b and is sealed to prevent air leakage. At the same time, in order to make the air pressure in each first moving channel 203b the same, the first moving channels 203b are connected to each other by a first air passage 203b-1. At the same time, a receiving groove 203c is provided inside the clamping block 203, and the receiving groove 203c is connected to the first moving channel 203b through a second air passage 203c-1. When the sliding rod 204 slides, gas exchange can occur between the first moving channel 203b and the receiving groove 203c, and then the inside of the receiving groove 203c is connected to the sliding cylinder 205 through a hose 206. A first elastic member 203d is fixedly installed at the bottom of the first moving channel 203b. The first elastic member 203d is a compression spring, and the other end of the first elastic member 203d is fixedly connected to the sliding rod 204. When the sliding rod 204 starts to press against the surface of the copper tube, at the same time, the first elastic member 203d starts to accumulate potential energy. When the copper tube is not pressed, the first elastic member 203d can reset the sliding rod 204.

[0051] Preferably, an airbag 203e is provided on the outer wall of the clamping block 203.

[0052] An airbag 203e is fixed to the outer wall of the clamping block 203. The advantage of this design is that when the two clamping blocks 203 approach each other, the airbag 203e also approaches. When the airbag 203e makes contact, there will be extrusion, which, in cooperation with the spring, provides a buffering effect for clamping.

[0053] Preferably, a third chute 201b is provided on the inner wall of the first rotating disk 201, and a first slider 207a that can slide along the inner wall of the third chute 201b is provided on the outer wall of the piston 207.

[0054] Here, it should be noted that the piston 207 penetrates through the first rotating disk 201 and the second rotating disk 202. The first rotating disk 201 is rotationally connected to the piston 207, and the second rotating disk 202 is fixedly connected to the piston 207. At the same time, a spiral upward third chute 201b is formed by inward concavity on the inner wall surface of the first rotating disk 201 in contact with the piston 207. A first slider 207a is fixedly installed on the outer wall of the piston 207. When the piston 207 moves towards the sliding cylinder 205, the first slider 207a slides along the inner wall of the third chute 201b. At the same time, since the piston 207 does not rotate, the first rotating disk 201 will rotate. Because the second rotating disk 202 does not rotate, the clamping blocks 203 begin to approach each other. That is, when the piston 207 moves towards the sliding cylinder 205, the second rotating disk 202 slides along the surface of the limiting cylinder 203a but does not detach, and at the same time, it can drive the clamping blocks 203 to approach each other to clamp the copper pipe. The advantage of this design is that when the piston 207 moves towards the sliding cylinder 205, the gas inside the sliding cylinder 205 will flow into the clamping block 203, and the air pressure will start to push the sliding rod 204 outwards. During the process of the sliding rod 204 being pushed outwards, the clamping blocks 203 are also approaching each other, so that the sliding rod 204 will be positioned along the surface of the copper pipe, and copper pipes with different radii can be clamped.

[0055] It should be noted here that the initial state of the sliding rod 204 is set such that half of it is inside the first moving channel 203b and the other part is outside the clamping block 203. When the piston 207 moves towards the sliding cylinder 205, the clamping blocks 203 start to approach each other. At this time, since the acting force of the air pressure on each sliding rod 204 is the same, the height difference between the sliding rods 204 will be maintained, and they will be pushed out synchronously; the advantage of this design is that in the initial state, the arrangement of the sliding rods 204 forms an arc-shaped groove. When the copper tube just touches the sliding rods 204, the copper tube will move towards the inside of the arc-shaped groove, allowing the shortest sliding rod 204 to contact the surface of the copper tube first, which can achieve a preliminary positioning. Subsequently, the sliding rods 204 start to press the outer surface of the copper tube. Since the piston 207 continuously advances and the air pressure gives an outward force to the sliding rods 204, the sliding rods 204 in contact with the outer surface of the copper tube will no longer move, and the sliding rods 204 that have not contacted the surface of the copper tube will continue to move outwards, providing space for the inside. When all the sliding rods 204 stop moving, the air pressure reacts against the piston 207, and the piston 207 can no longer move, that is, the first slider 207a cannot slide inside the third sliding groove 201b, and the first rotating disk 201 no longer rotates. It can not only clamp copper tubes with different radii but also achieve the preliminary positioning of the copper tube, ensuring that although the radii of the copper tubes are different, their axes are the same, and there is no need to continuously adjust the heights of the necking machine 102 and the chamfering machine 103.

[0056] Furthermore, a driving rod 208 is provided inside the sliding cylinder 205, and a magnetic attraction rod 208a is provided on the outer wall of the driving rod 208;

[0057] A fixing rod 207b is provided on the outer wall of the piston 207;

[0058] A second elastic member 209 is provided inside the sliding cylinder 205.

[0059] Among them, in order to automate the overall device, a driving rod 208 is slidably arranged inside the sliding cylinder 205, and the driving rod 208 is connected to a driving motor. The advantage of this design is that by changing the position of the driving motor, the driving rod 208 can slide inside the sliding cylinder 205, changing the internal space, adjusting the position of the sliding rod 204, indirectly changing the size of the clamping space, and increasing the range of the radius of the clamped copper pipe. At the same time, a magnetic attraction rod 208a is fixedly installed at one end of the driving rod 208 inside the sliding cylinder 205. That is, when the magnetic attraction rod 208a is energized, it can attract metals or magnetic poles. This is the prior art and will not be elaborated here. Correspondingly, a fixing rod 207b is installed at one end of the piston 207 close to the inside of the sliding cylinder 205, and a magnetizable material can be selected for production. A second elastic member 209 is sleeved on the outer wall of the magnetic attraction rod 208a. The second elastic member 209 is a compression spring and is arranged between the piston 207 and the driving rod 208. When energized, the magnetic attraction rod 208a starts to attract the fixing rod 207b, and the fixing rod 207b drives the piston 207 to move towards the sliding cylinder 205, while squeezing the second elastic member 209. Subsequently, the copper pipe is clamped, and the internal air pressure acts on the piston 207 in the reverse direction, and the piston 207 stops moving. Then, the driving motor is started to drive the sliding cylinder 205 to rotate, which can control the rotation of the first rotating disk 201 and adjust the orientation of the copper pipe.

[0060] Preferably, a fourth sliding groove 205a is provided on the inner wall of the sliding cylinder 205;

[0061] Second sliders 207b-1 that can slide along the fourth sliding groove 205a are provided on the outer walls of both the fixing rod 207b and the driving rod 208.

[0062] Among them, a semi-circular fourth sliding groove 205a is provided on the inner wall of the sliding cylinder 205, and semi-circular second sliders 207b-1 are fixedly installed on the outer walls of the fixing rod 207b and the driving rod 208, which can ensure that when the driving rod 208 rotates, it can drive the first rotating disk 201 to rotate.

[0063] Preferably, an arc groove 207c is formed by concave-convex on the outer wall of the piston 207.

[0064] Among them, an arc groove 207c is formed by concave-convex on the surface of the piston 207 facing the upper end.

[0065] In this solution, the sliding cylinder 205 can only rotate and cannot move. Therefore, a bracket can be made inside the chassis 101, and the sliding cylinder 205 is connected to the bracket through a bearing to ensure that it can rotate but not move.

[0066] In summary, the copper tube is placed on the surface of the arc groove 207c by the robotic arm. Subsequently, the magnetic attraction rod 208a is energized, and the piston 207 starts to move. Then, the clamping blocks 203 start to approach each other to clamp the copper tube. Subsequently, the necking machine 102 and the chamfering machine 103 are adjusted to process the copper tube. That is, the two ends of the copper tube are first aligned with the necking machine 102. If necking is required at both ends, the two necking machines 102 are started together. Subsequently, the drive motor is started to flip the copper tube so that the two ends of the copper tube are aligned with the chamfering machine 103, and then chamfers are made at both ends.

[0067] Embodiment 3

[0068] Referring to Figures 1 to 12 , which is the third embodiment of the present invention. The difference from the first three embodiments is that the chamfering machine 103 includes a chamfering tool 301, and the chamfering tool 301 includes an inclined surface 301a.

[0069] Among them, the chamfering tool 301 of the chamfering machine 103 is selected as a chamfering tool with an inclined surface 301a. In the prior art, a three-edge chamfering tool can be used. The advantage of having an inclined surface is that when processing a batch of copper tubes with the same radius, the robotic arm first places the copper tube on the surface of the arc groove 207c, and then starts to energize. Using magnetic attraction, the piston 207 starts to slowly move towards the sliding cylinder 205. During this process, the chamfering machines 103 are controlled to approach each other. When the sliding rod 204 sliding on the outer surface of the clamping block 203 lifts the copper tube, the tip of the chamfering tool 301 of the chamfering machine 103 starts to extend into the copper tube. At this time, the inner wall of the copper tube starts to move along the inclined surface 301a. Finally, when the radius of the inclined surface 301a is the same as the inner diameter of the copper tube, the axis of the copper tube is collinear with the cutting circumferential axis of the chamfering machine 103. Subsequently, the clamping blocks 203 continue to approach, and the sliding rod 204 starts to fit the surface of the copper tube, forming the optimal clamping effect for the copper tube with this radius.

[0070] Preferably, this solution is as Figure 10As shown, the third chute 201b is arranged on the inner wall of the second rotating disk 202. At the same time, in order to reduce the friction between the first rotating disk 201 and the piston 207, the piston 207 does not contact the first rotating disk 201; to reduce the influence of the rotation of the second rotating disk 202 on the first rotating disk 201, a rubber ring is placed between the first rotating disk 201 and the chassis 101 here to increase the friction between the two sides; that is, when the magnetic attraction rod 208a is electrified, the piston 207 moves and the second rotating disk 202 rotates. At this time, since the chamfering knives 301 at both ends clamp the copper tube and the copper tube restricts the rotation of the clamping block 203, the second rotating disk 202 begins to push the clamping blocks 203 closer to each other. When the clamping blocks 203 can no longer move, the second rotating disk 202 can no longer continue to rotate. At this time, the clamping profile has been formed. Subsequently, the driving motor rotates when needed. It should be noted here that during the processing, chamfering must be the last step completed. The advantage of this design is that after the chamfering process is completed, the two chamfering knives 301 do not retract. At this time, the driving motor rotates in reverse, and the second rotating disk 202 rotates. The copper tube clamps the clamping block 203 and cannot rotate, so the clamping blocks 203 begin to move away from each other; then the robotic arm clamps the copper tube, removes the chamfering knives 301, takes away the processed copper tube, and places the next copper tube to be processed. Subsequently, the driving motor starts, and the second rotating disk 202 begins to rotate. The copper tube falls into the formed profile, and the processes of clamping, rotating, necking, rotating, chamfering, and blanking are carried out. The process is processed according to the actual situation.

[0071] Preferably, a hydraulic rod 302 is externally connected to the necking machine 102 and the chamfering machine 103.

[0072] A hydraulic rod 302 is externally connected to the necking machine 102 and the chamfering machine 103, so that the working process can be adjusted according to the specific situation.

[0073] In summary, when it is necessary to batch process copper tubes of different radii, the magnetic attraction is turned off, the second elastic member 209 resets the piston 207, and then the sliding rod 204 resets.

[0074] Importantly, it should be noted that the construction and arrangement of the present application shown in multiple different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who refer to this disclosure should easily understand that many modifications are possible without materially departing from the novel teachings and advantages of the subject matter described in this application (such as installation arrangements, use of materials, color, orientation changes, etc.).
