Description

Technical Field

[0001] The invention relates to the technical field of muffler processing, and mainly to an air conditioner muffler processing device and a processing method thereof. Background Art

[0002] During the operation of the air conditioner, the discontinuous flow of refrigerant in the pipe system will generate pulsation noise, causing excessive indoor noise, thus affecting the user experience. Therefore, installing a silencer in the pipe system can effectively reduce this pulsation noise.

[0003] like Figure 1 As shown, the muffler generally includes a muffler body 100 and an intake pipe 200. A cover 300 with holes is welded at one end of the intake pipe 200, and a plurality of through holes are opened on the intake pipe 200. The intake pipe 200 is assembled in the muffler body 100 and fixed by welding. The traditional production steps of the intake pipe of the muffler are: metal skin raw material - metal pipe forming machine pipe (including welding) - drilling machine hole (making through holes on the intake pipe) - cover (cover is welded and fixed on the intake pipe) - drilling machine hole (making through holes on the cover). The traditional production method of the intake pipe of the muffler still has at least the following problems:

[0004] 1. The cover is fixed on the intake pipe by welding, and separate welding equipment is required to weld and fix the cover and the intake pipe. After welding the cover and the intake pipe, they need to be transferred to the drilling equipment for drilling, resulting in high equipment investment cost and high labor cost.

[0005] 2. The step of making the intake pipe through hole is after the pipe is made. Since the intake pipe is a round tube and the round tube is relatively smooth, the intake pipe is easy to move during drilling, causing the position of the intake pipe through hole to shift. When drilling, the hollow intake pipe is squeezed and deformed when subjected to the external force of the drill bit, which will affect the quality of the intake pipe and result in a high defective rate.

[0037] Embodiment 1:

[0038] Please refer to Figure 2-6 , an air conditioner muffler processing device, including a machine tool 1, a rotating fixture 2 is arranged on the side wall of the machine tool 1, an X-axis moving module 3 is also arranged on the machine tool 1, a Y-axis moving module 4 is arranged on the slide of the X-axis moving module 3, the rotating fixture 2 is used to clamp the workpiece and can drive the workpiece to rotate, the X-axis moving module 3 and the Y-axis moving module 4 can respectively drive the workpiece to move on the X-axis and the Y-axis, the rotating fixture 2, the X-axis moving module 3 and the Y-axis moving module 4 are commonly used devices on the CNC machine tool 1, so no more detailed description is made in this application. A processing mechanism and an automatic loading mechanism arranged side by side with the processing mechanism are arranged on the slide of the Y-axis moving module 4. Specifically, the processing mechanism includes a base 5, a capping assembly 6 and a drilling assembly 7. The base 5 is set on the slide of the Y-axis moving module 4 through fasteners. The base 5 is an I-shaped structure with an assembly cavity 501 on each side. The capping assembly 6 and the drilling assembly 7 are respectively arranged in the assembly cavity 501, wherein the capping assembly 6 is used to cap one end of the intake pipe, and the drilling assembly 7 is used to drill the intake pipe after capping. The present application integrates the capping and drilling of the intake pipe into the same device, reducing the cost investment of the equipment and the labor cost investment.

[0039] Specifically, the capping assembly 6 includes a first connecting body 601 of a hollow structure, a driving motor 602 and a roller 603. The first connecting body 601 is a square tube. The first connecting body 601 is arranged in the assembly cavity 501 and is fixed by a fastener, that is, the fastener is assembled in the pedestal 5 from the top, and the bottom is in contact with the outer surface of the first connecting body 601, so that the first connecting body 601 can be fixed in the assembly cavity 501. The driving motor 602 is arranged in the first connecting body 601, and the roller 603 is arranged on the output shaft of the driving motor 602. The driving motor 602 can drive the roller 603 to rotate when it works, and the required capping is formed by the rotation and extrusion of the workpiece and the roller 603.

[0040] Specifically, the drilling assembly 7 includes a second connector 701 of a hollow structure and a mounting cap 702. The second connector 701 is a circular tube. The second connector 701 is arranged in the assembly cavity 501 and fixed by a fastener, that is, the fastener is assembled in the pedestal 5 from the top, and the bottom is in conflict with the outer surface of the second connector 701, so that the second connector 701 can be fixed in the assembly cavity 501. The second connector 701 is arranged in the assembly cavity 501 and fixed by a fastener. The mounting cap 702 is detachably connected to the second connector 701. A drilling head 703 is arranged on the mounting cap 702. The mounting cap 702 has a hexagonal shape, which is convenient for disassembly of the mounting cap 702. An external thread is arranged on the outer wall of one end of the second connector 701, and an internal thread matching the external thread is arranged on the inner wall of the mounting cap 702, that is, the mounting cap 702 and the second connector 701 are connected together by threaded cooperation. The threaded connection method has the advantage of convenient installation and disassembly.

[0041] The specifications of the drilling head 703 are various, such as 3.0 mm, 3.5 mm, etc., which are used to process cover holes of different diameters and can be selected according to actual production needs.

[0042] Specifically, the automatic feeding mechanism includes a material storage table 8, a feed hopper 9 and a first cylinder 10. The material storage table 8 is arranged on the machine tool 1. A material storage groove 801 is arranged on the material storage table 8 and passes through both ends of the material storage table 8. The feed hopper 9 is arranged above the material storage table 8. The first cylinder 10 is arranged outside the material storage table 8. A push rod 11 is arranged on the output shaft of the first cylinder 10, and the push rod 11 is located in the material storage groove 801. The air intake pipe stored in the feed hopper 9 can fall into the material storage groove 801, and enter the rotating fixture 2 to be clamped and fixed under the push of the push rod 11, so as to facilitate the subsequent processing of the workpiece.

[0043] The feed hopper 9 is composed of two baffles 901, four baffles 902, four screws 903 and several nuts 904. The baffles 901 are respectively arranged on both sides of the storage platform 8. The screw 903 is arranged between the two baffles 901 and fixed by nuts 904. The baffles 902 include straight baffles 902 and bent baffles 902. The baffle 902 at the front end is a bent baffle 902, and the baffle 902 at the rear end is a straight baffle. The baffle 902 is arranged on the screw 903 and fixed by nuts 904.

[0044] The baffle 901 and the baffle bar 902 together form a material bin 905. Due to the shape of the bent baffle bar 902, the space in the upper part of the material bin 905 is large and the space in the lower part is small. The lower end of the material bin 905 faces the material storage trough 801, and the width of the lower end of the material bin 905 is slightly larger than the width of the material storage trough 801, so that the workpieces in the material bin 905 can smoothly enter the material storage trough 801.

[0045] Specifically, a second cylinder 12 is provided at the front end of the feed hopper 9, that is, a second cylinder 12 is provided at the position of the bending baffle 902, and a top block 13 is provided on the output shaft of the second cylinder 12. The top surface of the top block 13 is an inclined surface. Since an obtuse angle is formed at the bending baffle 902, the workpiece placed on the bending baffle 902 may be stuck above the feed hopper 9 and will not fall. The second cylinder 12 drives the top block 13 to apply external force to the workpiece, so that the workpiece can fall into the storage trough 801 to prevent the material from getting stuck.

[0046] The present invention is an air conditioner muffler processing device, and its working principle is described in conjunction with the accompanying drawings:

[0047] The staff first places the workpiece to be processed horizontally into the feed hopper 9. Under the action of free fall, the workpiece at the bottom will fall into the storage trough 801, and the remaining workpieces will be stacked together. The X-axis moving module 3 and the Y-axis moving module 4 work to drive the automatic feeding mechanism to approach the rotating fixture 2. The first cylinder 10 works to drive the push rod 11 to push the workpiece, and the workpiece in the storage trough 801 is transported to the rotating fixture 2. The push rod 11 is reset, and the new workpiece falls back into the storage trough 801. The rotating fixture 2 clamps the workpiece and drives the workpiece to rotate. The X-axis moving module 3 and the Y-axis moving module 4 work to drive the rotating roller head to gradually approach the workpiece, and the rotation of the workpiece and the roller 603 is used to produce the cover. The X-axis moving module 3 and the Y-axis moving module 4 work to drive the drilling head 703 to gradually approach the workpiece and drill holes in the workpiece cover.
