Technical Field

[0001] The invention relates to the field of automobile air-conditioning parts processing, and in particular to an automobile air-conditioning carbon dioxide air cooler header automatic processing system. Background Art

[0002] A manifold is a pipe that collects branch fluids into a main pipe and is used in automotive air conditioners. During the processing of the manifold, it is necessary to punch holes in the long manifold.

[0003] For example, Chinese patent CN221715435U discloses a punching mechanism for the side wall of a condenser header, which supports the punching position of the condenser header with the help of a header anti-deformation support mechanism during punching to avoid flattening the condenser header during punching. However, it has the following defects:

[0004] The internal support mechanism is always in contact and friction with the manifold when moving inside the manifold, which not only causes more wear marks on the inner wall of the manifold and affects the product quality, but also pushes the manifold and causes the position of the manifold to shift, affecting the accuracy of the punching position. Summary of the invention

[0005] In order to overcome the disadvantage that the existing internal support mechanism is always in contact and friction with the header when moving inside the header, thus affecting product quality, the present invention provides an automated processing system for a header of a carbon dioxide air cooler for an automobile air conditioner.

[0006] The technical implementation scheme of the present invention is: an automated processing system for a collecting pipe of a carbon dioxide air cooler for an automobile air conditioner, comprising the following working steps: Step 1: placing the collecting pipe on the clamping platform of a punching machine for clamping and fixing; Step 2: internally supporting the inner wall of the collecting pipe through a punching auxiliary module; Step 3: punching the collecting pipe through a punching machine; Step 4: monitoring the punching position of the collecting pipe during the punching process through a punching auxiliary module.

[0007] More preferably, the punching auxiliary module includes: a mounting seat, which is mounted on one side of the clamping platform of the punching machine; a driving telescopic member 1, of which two are provided, and all of the driving telescopic members 1 are mounted on the mounting seat; a spring telescopic plate, of which two are provided, and the telescopic end of each driving telescopic member 1 is connected to the fixed end of a spring telescopic plate; an inner top plate, the telescopic ends of the two spring telescopic plates are commonly connected to the inner top plate, a through hole extending from top to bottom is provided on the inner top plate, and the inner top plate is arranged in an arc shape; a lifting control component, which is installed on the fixed end of one of the spring telescopic plates, and the lifting and lowering of the inner top plate is controlled by the lifting control component.

[0008] More preferably, the lifting control assembly comprises: a fixed block, which is mounted on a fixed end of one of the spring telescopic plates; a driving telescopic member 2, which is mounted on the fixed block; a push plate, and two push plates are provided at the telescopic end of the driving telescopic member 2; one corner of the push plate is an inclined surface; a driven rod, which is provided with two driven rods, and both of the driven rods are mounted on the lower surface of the inner top plate, and when the driving telescopic member 2 drives the push plate to move, the inclined surface of the push plate moves and pushes the driven rod upward, and the driven rod moves up along the inclined surface of the push plate while driving the inner top plate to move up, and the spring telescopic plate cooperates to telescope.

[0009] More preferably, the driven rod is configured such that the width of the lower half is smaller than the width of the upper half, so that the lower half of the driven rod is broken first.

[0010] More preferably, a connecting rope is connected between the upper half of the driven rod and the lower half of the driven rod.

[0011] More preferably, a notch is provided on the side of the driven rod, and the notch is located at the boundary between the upper half of the driven rod and the lower half of the driven rod.

[0016] Compared with the prior art, the present invention has the following advantages: the present invention designs a lifting inner top plate, so that the inner top plate does not contact the inner top wall of the collecting tube during the movement of the inner top plate in the collecting tube, thereby avoiding friction between the inner top plate and the inner top wall of the collecting tube. This not only reduces the wear of both, ensures that the inner top wall of the collecting tube is free of scratches and wear, and improves product quality, but also avoids the problem of position displacement of the collecting tube due to friction with the inner top plate, and ensures the alignment of the collecting tube during continuous punching.

[0017] When the punching hole is offset, the lower half of the driven rod with a smaller width is broken by impact under the restriction of the ejection plate, so as to protect the inner top plate from being deformed by impact. Since the inner top plate needs to be customized according to the size of the manifold, the cost is relatively high, so the driven rod is replaced as a wearing part to reduce the production cost. At the same time, the distance between the inner top plate and the ejection plate changes, and a signal of the distance change is received by an infrared receiver, and an alarm is sent to the host control system, so that the staff can be informed of the situation in time and take corresponding measures.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1

[0025] An automated processing system for a manifold of a carbon dioxide air cooler for an automobile air conditioner comprises the following working steps: step one: placing the manifold on a clamping platform of a punching machine for clamping and fixing; step two: providing internal support to the inner wall of the manifold by means of a punching auxiliary module; step three: performing a punching operation on the manifold by means of the punching machine; and step four: monitoring the punching position of the manifold during the punching process by means of the punching auxiliary module.

[0026] like Figure 1-Figure 3 As shown, the punching auxiliary module includes:

[0027] A mounting base 1, wherein the mounting base 1 is mounted on one side of the clamping platform of the punching machine;

[0028] A driving telescopic member 2, wherein two driving telescopic members 2 are provided, and all of the driving telescopic members 2 are mounted on the mounting seat 1;

[0029] A spring telescopic plate 3, wherein two spring telescopic plates 3 are provided, and the telescopic end of each of the driving telescopic members 2 is connected to a fixed end of a spring telescopic plate 3;

[0030] An inner top plate 4, the telescopic ends of the two spring telescopic plates 3 are connected to the inner top plate 4, the inner top plate 4 is provided with a through hole 41 which passes through from top to bottom, the through hole 41 is located between the two spring telescopic plates 3, and the inner top plate 4 is arranged in an arc shape;

[0031] A lifting control component is installed on a fixed end of one of the spring telescopic plates 3.

[0032] The lifting control assembly comprises:

[0033] A fixed block 5, wherein the fixed block 5 is mounted on a fixed end of one of the spring expansion and contraction plates 3;

[0034] A second driving telescopic member 6, wherein the second driving telescopic member 6 is mounted on the fixed block 5;

[0035] Pushing plate 7, two pushing plates 7 are provided at the telescopic end of the driving telescopic member 2 6; one corner of the pushing plate 7 is an inclined surface;

[0036] The driven rod 8 is provided with two driven rods 8 , and the two driven rods 8 are both installed on the lower surface of the inner top plate 4 .

[0037] The driving telescopic member 1 2 and the driving telescopic member 2 6 are both electric push rods.

[0038] When the punching hole 41 is aligned with the punching position of the collector, the driving telescopic member 2 stops running, and then the driving telescopic member 2 6 is controlled to drive the push plate 7 to move, so that the inclined surface of the push plate 7 moves and pushes the driven rod 8 upward. The driven rod 8 moves up along the inclined surface of the push plate 7 while driving the inner top plate 4 to move upward. The spring telescopic plate 3 cooperates to telescope, so that the inner top plate 4 moves up to contact with the inner top wall of the collector, thereby supporting the inner top wall of the collector through the inner top plate 4, so as to avoid the problem of the collector being concave and deformed at the hole position when punching. The waste material punched out by the punching machine falls downward through the through hole 41.

[0039] Furthermore, since a row of holes needs to be punched on the collecting tube, the inner top plate 4 needs to be moved to different positions for internal support. Before the inner top plate 4 moves in the collecting tube, it is necessary to control the driving telescopic member 2 6 to retract so that the pushing plate 7 no longer pushes the driven rod 8. Under the rebound action of the spring telescopic plate 3, the inner top plate 4 moves down and breaks contact with the inner top wall of the collecting tube, so that the inner top plate 4 does not contact the inner top wall of the collecting tube during the movement of the inner top plate 4 in the collecting tube, thereby avoiding friction between the inner top plate 4 and the inner top wall of the collecting tube, which can not only reduce the wear of both, ensure that the inner top wall of the collecting tube is free of scratches and wear, and improve product quality, but also avoid the problem of position displacement of the collecting tube due to friction with the inner top plate 4, thereby ensuring the alignment of the collecting tube during continuous punching.

[0040] Example 2

[0041] On the basis of Example 1, Figure 1-Figure 4 As shown, the driven rod 8 is configured such that the width of the lower half is smaller than the width of the upper half, and the lower end of the driven rod 8 is a curved surface.

[0042] A connecting rope 9 is connected between the upper half of the driven rod 8 and the lower half of the driven rod 8 .

[0043] A notch 81 is formed on the side of the driven rod 8 , and the notch 81 is located at the boundary between the upper half of the driven rod 8 and the lower half of the driven rod 8 .

[0044] An infrared receiver is arranged on the top horizontal plane of the push plate 7 , and an infrared transmitter is arranged on the inner arc surface of the inner top plate 4 .

[0045] In this embodiment, during the punching process of the collecting pipe, the inner top plate 4 moves up to contact the inner top wall of the collecting pipe. When the punching machine fails or the clamping platform fails or other factors fail, causing the punching position of the collecting pipe to shift, the punching head of the punching machine cannot be aligned with the through hole 41 up and down, so when the punching head of the punching machine punches downward, the punching head will hit the inner top plate 4, so the follower rod 8 is designed to have a lower half width that is smaller than the upper half, and because the inner top plate 4 can move up and down under the action of the spring expansion plate 3, the impact force of the punching head on the inner top plate 4 is transmitted to the driven rod 8, so that the lower half of the driven rod 8 with a small width is broken by the impact under the restriction of the push plate 7, protecting the inner top plate 4 from deformation by the impact. Since the inner top plate 4 needs to be customized according to the size of the collecting pipe, the cost is relatively high, so the driven rod 8 is replaced as a wearing part to reduce production costs.

[0046] Furthermore, when the inner top plate 4 moves up to contact the inner top wall of the manifold, the distance between the inner top plate 4 and the push plate 7 is a fixed value. An infrared receiver is arranged on the top horizontal plane of the push plate 7, and an infrared transmitter is arranged on the inner arc surface of the inner top plate 4, so as to monitor the distance between the inner top plate 4 and the push plate 7. When the above-mentioned fault occurs, when the inner top plate 4 is hit by the punching head of the punching machine and moves down, the distance between the inner top plate 4 and the push plate 7 changes, and a signal of the distance change is received by the infrared receiver, and an alarm is sent to the host control system, so that the staff can be informed of the situation in time and take corresponding measures.

[0047] Furthermore, by providing the connecting rope 9, the lower half of the driven rod 8 will be pulled by the connecting rope 9 when it breaks, so that the lower half of the driven rod 8 will not splash out at will, thereby avoiding damage to other parts or workers, and by the design of the notch 81, the breaking position of the driven rod 8 is as close as possible to the boundary between the upper half and the lower half, thereby ensuring that the connecting rope 9 can be effectively used to the greatest extent and preventing the broken part from splashing.

[0048] Example 3

[0049] On the basis of Example 2, Figure 1-Figure 3 As shown, a push plate 10 is connected between the two push plates 7 .

[0050] The lower end of the push plate 10 is curved, and the push plate 10 covers between the inner top plate 4 and the inner bottom wall of the collecting tube, and the push plate 10 does not contact the inner bottom wall of the collecting tube. The curved design of the lower end of the push plate 10 minimizes the gap between the push plate 10 and the inner bottom wall of the collecting tube, ensuring that the punching waste can be pushed out.

[0051] A caster 11 is respectively installed on the outer side of the fixed end of the two spring expansion plates 3. The casters 11 roll on the inner wall of the manifold, which not only plays a supporting role but also assists the movement of the spring expansion plates 3 and the inner top plate 4 inside the manifold.

[0052] In this embodiment, the push plate 10 is initially located on one side below the through hole 41. After the push plate 7 moves through the inclined surface to push the driven rod 8 upward, the push plate 7 continues to move. At this time, the driven rod 8 contacts the upper horizontal surface of the push plate 7 until the push plate 10 is located on the other side below the through hole 41. At this time, the push plate 7 stops moving, and then the punching operation is performed. The punched waste falls to one side of the push plate 10. After all holes are punched, all the punched waste is located on the same side of the push plate 10. When the push plate 10 retreats and moves out of the collecting pipe, all the punched waste is pushed out by the push plate 10, and the staff can place a collection box at the corresponding position to collect the punching waste.

[0053] Furthermore, the push plate 10 is covered between the inner top plate 4 and the inner bottom wall of the collecting tube, which can shield the punching waste and prevent the punching waste from splashing to the other side of the push plate 10, thereby ensuring that all the punching waste is located on the same side of the push plate 10, which is convenient for subsequent unified pushing and collection.
