[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] Reference Figures 1 to 7, which is the first embodiment of the present invention, provides an integrated device for shrinking, chamfering, and cutting refrigeration equipment pipes, comprising a support assembly 100, including a chassis 101, a shrinking machine 102 and a chamfering machine 103 provided on the surface of the chassis 101, and a slide rail 104 provided on the surface of the chassis 101 for the shrinking machine 102 and the chamfering machine 103 to slide;

[0038] The clamping assembly 200 includes a first rotating disk 201 rotatably connected to the chassis 101, a first slide 201a provided within the first rotating disk 201, a second rotating disk 202 provided on a surface of the first rotating disk 201, a second slide 202a provided within the second rotating disk 202, a clamping block 203 provided on a 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 is provided on the outer wall of the clamping block 203 and can slide along the first slide groove 201a and the second slide groove 202a, a slide cylinder 205 is connected to the first rotating disk 201 and the second rotating disk 202, and a hose 206 is connected between the slide cylinder 205 and the limiting cylinder 203a;

[0040] The piston 207 is provided inside the slide cylinder 205 .

[0041] Among them, the chassis 101 adopts a hollow box body, which contains some other equipment required for processing; the upper surface of the chassis 101 is installed with a shrinking machine 102 and a chamfering machine 103, wherein the shrinking machine 102 and the chamfering machine 103 can adopt the copper pipe processing equipment on the market, which is the existing technology and will not be repeated here; at the same time, the shrinking machine 102 and the chamfering machine 103 are symmetrically arranged on the surface of the box body 101. Two; the shrinking machine 102 and the chamfering machine 103 are arranged on the slide rail 104, so that the position of the shrinking machine 102 and the chamfering machine 103 can be adjusted.

[0042] The first rotating disk 201 is rotatably mounted on the upper surface of the chassis 101, and the second rotating disk 202 is mounted 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 sliding groove 201a passes through the first rotating disk 201, and the second sliding groove 202a passes through the second rotating disk 202, and Figure 7 As 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 shown in FIG. Figure 5As shown, the clamping block 203 is a fan-shaped structure, and the clamping block 203 is a cavity structure. A limiting cylinder 203a is fixedly installed on the lower surface of the clamping block 203, and the limiting cylinder 203a passes through the first slide groove 201a and the second slide groove 202a. When the second rotating disk 202 rotates, the second slide groove 202a will push the limiting cylinder 203a to slide along the inner wall of the second slide groove 202a. At the same time, due to the restriction of the first slide groove 201a, the limiting cylinder 203a slides along the inner wall of the first slide groove 201a; so the clamping blocks 203 will approach each other. If the second rotating disk 202 is reversed, the clamping blocks 203 will move away from each other; sliding rods 204 are slidably installed on both sides of the fan-shaped clamping block 203, and a plurality of sliding rods 204 are arranged in a horizontal and vertical array, and the lengths of the sliding rods 204 are different, forming a Figure 6 The advantage of the inward concave arc groove shown in this design is that when the second rotating disk 202 rotates, the clamping blocks 203 will approach each other. Since the copper tube is a cylindrical structure, the outer wall surface will first slide into the inward concave arc groove, and then the clamping blocks 203 will 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 limit cylinder 203a, and the other end is connected to the slide cylinder 205. A sliding piston 207 is provided inside the slide cylinder 205. The end of the slide 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 slide cylinder 205 is connected to the first rotating disk 201 and the second rotating disk 202. In this solution, the slide cylinder 205 passes through the second rotating disk 202 but does not pass through the first rotating disk 201. The advantage is that the slide 205 is fixedly connected to the second rotating disk 202. When the slide 205 is rotated, the clamping blocks 203 are pushed to approach each other at the same time. Subsequently, the slide bar 204 begins to contact the outer surface of the copper tube and begins to squeeze the copper tube. Subsequently, the slide bar 204 begins to move inside the clamping block 203. Subsequently, the internal gas of the clamping block 203 begins to flow inside the slide 205 and begins to push the piston 207 to slide. Subsequently, the piston 207 contacts the first rotating disk 201. Subsequently, the slide bar 204 no longer slides and clamps the copper tube. Then, according to demand, the necking machine 102 or the chamfering machine 103 is controlled to process the copper tube. If both necking and chamfering are required, the slide 205 can be rotated to adjust the clamped copper tube by 90 °, align with the necking machine 102 or the chamfering machine 103, and then process. If cutting is required, a truss can be set above the chassis 101, and a hydraulic system can be used on the truss to control the movement and lifting of the cutting machine; then the clamping assembly 200 is used to clamp the copper pipe, and then the hydraulic system is used to control the lifting of the cutting machine to cut the corresponding position. This existing technology is relatively mature and will not be described in detail.

[0044] Example 2

[0045] Reference Figures 1 to 8, which is the second embodiment of the present invention, is different from the first embodiment in that: there are four clamping blocks 203 in the array.

[0046] Among them, such as Figure 2 As shown, four clamping blocks 203 are provided on the surface of the first rotating disk 201. The advantage of this design is that a horizontal clamping block and a vertical clamping block can be formed. Figure 1 As 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 processing efficiency.

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

[0048] A first elastic member 203d is provided inside the first movable channel 203b;

[0049] The receiving tank 203 c is connected to the slide cylinder 205 through the hose 206 .

[0050] Among them, such as Figure 4 As shown, a plurality of first movable channels 203b are arranged in an array inside the clamping block 203, and the slide rod 204 slides along the inner wall of the first movable channel 203b and is sealed to prevent air leakage; at the same time, in order to make the air pressure inside each first movable channel 203b the same, the first air channel 203b-1 is used to connect the first movable channels 203b to each other; 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 movable channel 203b through the second air channel 203c-1. When the slide rod 204 slides The first movable channel 203b and the accommodating groove 203c can exchange gas, and then the interior of the accommodating groove 203c is connected to the slide 205 through the hose 206; a first elastic member 203d is fixedly installed at the bottom of the first movable channel 203b, and the first elastic member 203d adopts a compression spring, and the other end of the first elastic member 203d is fixedly connected to the slide rod 204; when the slide rod 204 begins to squeeze the surface of the copper tube, the first elastic member 203d begins to accumulate potential energy at the same time. When the copper tube is no longer squeezed, the first elastic member 203d can reset the slide rod 204.

[0051] Preferably, an air bag 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 begins to approach. When the airbag 203e comes into contact, there will be squeezing, and cooperate with the spring to have a buffering effect on the clamping.

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

[0054] It should be noted that the piston 207 penetrates the first rotating disk 201 and the second rotating disk 202, and the first rotating disk 201 is rotatably connected to the piston 207, and the second rotating disk 202 is fixedly connected to the piston 207. At the same time, the inner wall surface of the first rotating disk 201 where the piston 207 contacts is concave to form a third chute 201b spiraling upward. The outer wall of the piston 207 is fixedly mounted with a first slider 207a. When the piston 207 moves toward the slide 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 rotates, and since the second rotating disk 202 does not rotate, the clamping blocks 203 begin to approach each other. That is, when the piston 207 moves toward the slide 205, the second rotating disk 202 slides along the surface of the limit cylinder 203a, but does not disengage, and can also drive the clamping blocks 203 to approach each other, clamping the copper tube. The advantage of this design is that when the piston 207 moves toward the slide 205, the gas inside the slide 205 will flow into the clamping block 203, and the air pressure will begin to push the slide rod 204 outward; in the process of the slide rod 204 being pushed outward, the clamping blocks 203 are also approaching each other, so that the slide rod 204 will fall along the surface of the copper tube, and can clamp copper tubes of different radii.

[0055] It should be noted here that the initial state of the slide rod 204 is that half of it is inside the first movable channel 203b and the other part is outside the clamping block 203. When the piston 207 moves toward the slide cylinder 205, the clamping blocks 203 begin to approach each other. At this time, since the air pressure exerts the same force on each slide rod 204, the slide rods 204 will maintain the original height difference and move outward synchronously. The advantage of this design is that in the initial state, the arrangement of the slide rods 204 forms an arc groove. When the copper tube just contacts the slide rod 204, the copper tube will move into the arc groove. The shortest slide bar 204 is first brought into contact with the copper tube surface to achieve a preliminary positioning. Subsequently, the slide bar 204 begins to pressurize the outer surface of the copper tube. As the piston 207 continues to advance, the air pressure exerts an outward force on the slide bar 204. Therefore, the slide bar 204 that is in contact with the outer surface of the copper tube no longer moves, while the slide bar 204 that is not in contact with the copper tube surface continues to move outward, thereby providing space for the interior. When all slide bars 204 are no longer 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 chute 201b, and the first rotating disk 201 no longer rotates. This can not only achieve the clamping of copper tubes of different radii, but also achieve the preliminary positioning of the copper tubes, ensuring that although the copper tubes have different radii, their axes are the same, without the need to constantly adjust the heights of the necking machine 102 and the chamfering machine 103.

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

[0057] The outer wall of the piston 207 is provided with a fixing rod 207b;

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

[0059] Among them, in order to make the whole equipment automated, a driving rod 208 is set to slide inside the slide 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 along the inside of the slide 205, changing the internal space, and adjusting the position of the slide rod 204, indirectly changing the size of the clamping space, and increasing the range of the radius of the clamping copper tube. At the same time, the driving rod 208 is fixedly installed with a magnetic rod 208a at one end inside the slide cylinder 205, that is, when the magnetic rod 208a is energized, it can attract metal or magnetic poles. This is a prior art and will not be repeated here. Correspondingly, a fixed rod 207b is installed at one end of the piston 207 near the inside of the slide cylinder 205, which can be made of a material that can be magnetically attracted. A second elastic member 209 is sleeved on the outer wall of the magnetic rod 208a, which is a compression spring and is arranged between the piston 207 and the driving rod 208. When power is turned on, the magnetic rod 208a begins to attract the fixed rod 207b, and the fixed rod 207b starts to move toward the slide cylinder 205 with the piston 207, while squeezing the second elastic member 209. Subsequently, the copper tube is clamped, and the internal air pressure reacts on the piston 207, and the piston 207 no longer moves. Subsequently, the driving motor is started to drive the slide cylinder 205 to rotate, which can control the rotation of the first rotating disk 201 and adjust the direction of the copper tube.

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

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

[0062] Among them, a semicircular fourth sliding groove 205a is provided on the inner wall of the slide cylinder 205, and a semicircular second slider 207b-1 is fixedly installed on the outer wall of the fixed rod 207b and the driving rod 208, so as to ensure that when the driving rod 208 rotates, it can drive the first rotating disk 201 to rotate.

[0063] Preferably, the outer wall of the piston 207 is concave to form an arc groove 207c.

[0064] The surface of the piston 207 facing the upper end is concave to form an arc groove 207c.

[0065] In this solution, the slide 205 can only rotate but not move, so a bracket can be made inside the chassis 101, and the slide 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 using a robotic arm, and then the magnetic rod 208a is energized, the piston 207 starts to move, and then the clamping blocks 203 begin to approach each other to clamp the copper tube, and then the shrinking machine 102 and the chamfering machine 103 are adjusted to process the copper tube, that is, first align the two ends of the copper tube with the shrinking machine 102. If both ends need to be shrunken, the two shrinking machines 102 are started together; then 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 the two ends are chamfered.

[0067] Example 3

[0068] Reference Figures 1 to 12 , which is the third embodiment of the present invention, is different from the first three embodiments in that the chamfering machine 103 includes a chamfering knife 301, and the chamfering knife 301 includes a bevel 301a.

[0069] Among them, the chamfering knife 301 of the chamfering machine 103 uses a chamfering knife with a bevel 301a. A three-edged chamfering knife can be used in the prior art. The advantage of having a bevel is that when processing a batch of copper tubes with the same radius, the copper tube is first placed on the surface of the arc groove 207c with a robotic arm, and then the power is turned on. By using magnetic attraction, the piston 207 begins to move slowly toward the slide cylinder 205. During this process, the chamfering machines 103 are controlled to approach each other. When the slide rod 204 sliding on the outer surface of the clamping block 203 lifts the copper tube, the tip of the chamfering knife 301 of the chamfering machine 103 begins to extend toward the inside of the copper tube. At this time, the inner wall of the copper tube begins to move along the bevel 301a. Finally, when the radius of the bevel 301a is the same as the inner diameter of the copper tube, the axis of the copper tube is in line with the cutting circle axis of the chamfering machine 103. Then the clamping block 203 continues to approach, and the slide rod 204 begins to fit the surface of the copper tube, forming the optimal clamping effect for the copper tube of this radius.

[0070] Preferably, this solution is as Figure 10As shown, the third chute 201b is set 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 and the first rotating disk 201 do not contact each other. In order to reduce the impact of the rotation of the second rotating disk 202 on the first rotating disk 201, a circle of rubber is placed between the first rotating disk 201 and the chassis 101 to increase the friction between the two sides. That is, when the magnetic rod 208a is energized, the piston 207 moves and the second rotating disk 202 rotates. At this time, because the chamfering cutters 301 at both ends clamp the copper tube, the copper tube restricts the rotation of the clamping block 203, so 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 rotate. At this time, the clamping profile has been formed. The drive motor then rotates when needed. What needs to be noted here is that chamfering must be the last to be completed during the processing. The advantage of this design is that after the chamfering is completed, the two chamfering cutters 301 are not withdrawn. At this time, the drive motor reverses, the second rotary disk 202 rotates, and the copper tube is stuck in 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 cutter 301, takes away the processed copper tube, and puts in the next copper tube to be processed. Then the drive motor starts, the second rotary disk 202 starts to rotate, and the copper tube falls into the formed contour, clamping, rotating, shrinking, rotating, chamfering, and unloading. The process is processed according to actual conditions.

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

[0072] The hydraulic rod 302 is connected to the outside of the necking machine 102 and the chamfering machine 103, so that the work flow can be adjusted according to specific circumstances.

[0073] In summary, when the copper tubes with different radii need to be processed in batches, the magnetic attraction is turned off, the second elastic member 209 resets the piston 207, and then the slide rod 204 is reset.
