TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic processing equipment, in particular to an automatic net installing and diameter expanding machine. BACKGROUND

[0002] The liquid accumulator is an important component of the compressor, which plays a series of roles such as storage, gas-liquid separation, filtering, sound attenuation and refrigerant buffering, and is usually composed of a body, two end covers, a net rack and a branch pipe, etc. The net rack is positioned in the middle of the body. The existing technology usually adopts direct pressing during the pressing process of the two.

[0003] However, during the long-term assembly and processing of the liquid accumulator, it is found that the existing technology still has some disadvantages: 1. The net rack is directly pressed, but once a slight inclination occurs at the opening position of the body, the opening of the body will be deformed under forced pressing, and even a slight cracking phenomenon will occur, which will affect the product quality; 2. During the direct pressing process, the net rack will cause a certain diameter expansion of the body, and the deformation of the inner wall of the body will cause a lot of iron filings to fall off, which will affect the subsequent processing and even the use effect of the final product if the iron filings cannot be completely removed. SUMMARY

[0004] The purpose of the present application is to provide an automatic net installing and diameter expanding machine to solve the above-mentioned defects in the prior art.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 5 As shown, an automatic wire mesh expansion machine includes a frame 1, a mounting frame 2, a protective pressing mechanism 3, and a chip removal mechanism 4. The mounting frame 2 is fixedly installed on the upper end of the frame 1, and a fixed frame 5 is also provided at the bottom of the mounting frame 2. The protective pressing mechanism 3 is installed on the fixed frame 5 and is used to press the wire mesh 7 into the interior of the liquid storage container 6 in a directional manner. The chip removal mechanism 4 is also installed on the fixed frame 5 and is used to remove iron filings falling from the lower port of the liquid storage container 6.

[0022] In this embodiment, the protective pressing mechanism 3 includes a drive motor 301, a lower gear disc 302, and a pressing ball 303. The drive motor 301 is mounted on the bottom of the frame 1. A lead screw 304 is mounted on the output end of the drive motor 301. The other end of the lead screw 304 is rotatably mounted on the fixed frame 5. A slider 305 is threaded onto the lead screw 304. A mounting base 307 is connected to the slider 305 via two symmetrically arranged sliding rods 306. The pressing ball 303 is detachably mounted on the mounting base 307. The upper end of the lever 304 is also coaxially fixedly connected to a vertical rotating shaft 308. The lower gear 302 is fixedly installed on the vertical rotating shaft 308. A horizontal rotating shaft 309 is rotatably installed on the mounting bracket 2. A gear 310 that meshes with the lower gear 302 is installed at one end of the rotating shaft. A cam 311 is also installed in the middle of the horizontal rotating shaft 309. A C-shaped placement seat 312 is also fixedly installed on the mounting bracket 2. A positioning base 313 is slidably installed on the upper limit of the C-shaped placement seat 312. The liquid storage container body 6 is placed in the positioning base 313.

[0023] In this embodiment, the chip removal mechanism 4 includes an air source 41, an upper gear plate 42, and an air jet head 43. The air source 41 is installed on the upper end of the vertical rotating shaft 308. The air source 41 is connected to the air jet head 43 through a control valve 44 and an air guide pipe 45. The upper gear plate 42 is rotatably installed on the upper part of the vertical rotating shaft 308, and the upper gear plate 42 meshes with the gear 310.

[0024] It should be noted that the upper inner wall of the positioning base 313 is fitted with the outer wall of the liquid reservoir body 6.

[0025] In this embodiment, the press-fit ball 303 is also provided with a number of evenly distributed positioning rods 315 in a circumferential manner via a tension spring 314. The lower end of the press-fit ball 303 and the positioning rods 315 are both in cooperation with the grid frame 7.

[0026] It is worth noting that the lower end of the positioning base 313 is engaged with the outer edge of the cam 311, and the lower end of the positioning rod 315 is chamfered.

[0027] Furthermore, the jet path of the jet head 43 mates with the opening of the C-shaped placement seat 312 in the horizontal direction.

[0028] Working process and principle: In the process of using this invention, the liquid storage container body 6 to be pressed is first placed on the positioning base 313 with the constricted end facing down. The drive motor 301 is started so that its output end drives the lead screw 304 to rotate. While driving the slider 305 to move down, it also drives the lower gear plate 302 and the vertical rotating shaft 308 to rotate at the same time.

[0029] During the downward movement of slider 305, the sliding rod 306 and mounting base 307 drive the pressing ball 303 to move downward. The positioning rod 315 on the pressing ball 303 is inserted into the perforated mating point on the mesh frame 7 through the chamfered guide end. At the same time, the rounded end of the lower top of the pressing ball 303 is pushed into the circular concave structure in the middle of the mesh frame 7. At this time, the tension spring 314 is in a stretched state until all the positioning rods 315 are placed into the perforated mating point, ensuring that the mesh frame 7 is pressed into the upper port of the liquid storage body 6 in a vertical state. In this way, the mesh frame 7 is firmly pressed into the precise position inside the liquid storage body 6. The positioning base, under the cover of 313, ensures that the outer wall of the liquid storage body, i.e., the outer diameter, remains unchanged, and only the inner diameter of the pressing increases, i.e., the inner wall of the pressing path becomes thinner.

[0030] During the rotation of the lower gear plate 302, the cam 311 will be driven to rotate via the gear 310 and the transverse rotating shaft 309. The outer edge of the cam 311 will quickly vibrate and strike the lower end of the positioning base 313, thereby causing all the iron filings that fall off during the pressing process to return and be discharged from the constricted end of the liquid reservoir body 6. At the same time, the rotation of the gear 310 will drive the upper gear plate 42 to rotate synchronously, so that the airflow generated by the air source 41 will be ejected from the rotating jet head 43 through the control valve 44 and the air guide pipe 45, and pointed to the side of the opening of the C-shaped placement seat 312 in the same horizontal direction.

[0031] Based on the above, the present invention sets a protective pressing mechanism 3 and a chip removal mechanism 4 on the fixed frame 5. The output end of the drive motor 301 drives the lead screw 304 to rotate, which drives the slider 305 to move down, so that all the positioning rods 315 are placed into the punched mating area, ensuring that the mesh frame 7 is pressed into the upper port of the liquid storage container 6 in a vertical state. In this way, the mesh frame 7 is firmly pressed into the precise position inside the liquid storage container 6. The positioning base, under the cover of 313, ensures that the outer wall of the liquid storage container, i.e., the outer diameter, remains unchanged. Only the inner diameter of the pressing increases, i.e., the inner wall of the pressing path becomes thinner, avoiding slight tearing and ensuring product quality.

[0032] During the rotation of the lower gear plate 302, the cam 311 will rotate via the gear 310 and the transverse rotating shaft 309. The outer edge of the cam 311 will quickly vibrate and strike the lower end of the positioning base 313, thereby causing all the iron filings that fall off during the pressing process to return and be discharged from the constricted end of the liquid reservoir body 6. At the same time, the rotation of the gear 310 will drive the upper gear plate 42 to rotate synchronously, so that the airflow generated by the air source 41 will be ejected from the rotating jet head 43 through the control valve 44 and the air guide pipe 45, and pointed to the side of the opening of the C-shaped placement seat 312 in the same horizontal direction, thereby quickly removing the fallen iron filings.

[0033] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
